Description

Fixing seat for switch box

This creation is related to the fixing seat, especially a kind of fixing seat used for the switch box.

Conventional switch boxes are mostly embedded directly in a recess in a wall during the construction of a building, so that the ends of the wires are allowed to be arranged in the switch box so as to facilitate the configuration of switches or sockets. However, under long-term use, the switch box is easily corroded and damaged due to environmental humidity, material life and other factors, so that it cannot be used in combination with a switch cover. If you want to replace the switch box, you need to knock or destroy the wall or the switch box to take out the original switch box, and the new switch box may not be stably fixed due to factors such as inappropriate size and changes in the notch structure of the wall. If it is arranged in the notch, problems such as difficult construction and poor bonding stability are caused.

Therefore, it is necessary to provide a novel and progressive fixing seat for a switch box to solve the above-mentioned problems.

The main purpose of this creation is to provide a fixed base for the switch box, which is easy to install, has a wide range of applications and is beneficial to the maintenance and replacement of the switch box.

In order to achieve the above purpose, the invention provides a fixed seat for a switch box, comprising: two frames, connected to each other and enclosing a frame opening, each of which includes at least one first locking portion extending toward the inside of the frame opening, The two frames can move relatively along a moving direction to change the size of the frame opening.

The following examples are only used to illustrate the possible implementation of this creation, but it is not intended to limit the scope of protection of this creation, and it will be described first.

Please refer to Fig. 1 to 7, it shows the first preferred embodiment of this creation, and the fixed seat 1 that is used for switch box of this creation comprises two frames 10, is connected with each other and surrounds a frame mouth 11, and each this frame 10 comprises At least one first locking portion 12 extending toward the inner side of the frame opening 11, the two frames 10 can move relative to each other along a moving direction M to change the size of the frame opening 11, so as to be suitable for installation openings of different sizes. The fixing seat 1 can be directly installed and abutted against the inner side wall of the old switch box 2 or an opening reserved on a wall 3 without removing the old switch box 2. The at least one first locking part 12 can be worn by a fastener to connect a switch cover 4, which is beneficial to the maintenance and replacement of the switch box 2 and has a wide range of applications.

Each of the frames 10 further includes two opposite arm portions 13 at intervals, and the two arm portions 13 of one of the two frames 10 overlap and connect with the other of the two frame 10 along a thickness direction, by The connection of the two frames 10 can have better structural strength. At least one of the two frames 10 further includes a guide portion 14, and the guide portion 14 of one of the two frames 10 can block the other of the two frames 10 in a direction transverse to the moving direction M. Firstly, the two frames 10 are prevented from skewing relative to each other during adjustment. Furthermore, each of the connecting parts 14 includes a plurality of blocking pieces 141, and the plurality of blocking pieces 141 are arranged on two opposite sides of the frame 10 in a width direction W, so as to stably clamp and guide the two arms. The portion 13 relatively slides along the moving direction M. As shown in FIG. In other embodiments, a connecting structure can also be provided between the two frames, such as but not limited to connecting rods, sleeves, concave-convex structures that can be buckled together, etc., and can also achieve an adjustable connection between the two frames The effect.

In this embodiment, the extension lengths of the two arm portions 13 of each frame 10 are the same; the two arm portions 13 of each frame 10 include a first arm portion 131 and a second arm portion 132, and each second arm portion 132 The arm portion 132 is provided with a guide portion 14 capable of receiving the first arm portion 131; each guide portion 14 includes two blocking pieces 141 completely aligned in the width direction W, and each blocking piece 141 It protrudes from a side of the second arm portion 132 facing the frame opening 11 , which has good assembly stability and can avoid interference and is conveniently installed in the switch box 2 . Preferably, the two frames 10 have the same shape and are integrally formed as a single component, which is easy to manufacture, has good structural strength and can greatly reduce production costs. In other embodiments, the number of the plurality of blocking pieces of each of the guiding parts can also be more than two.

At least one of the two frames 10 further includes at least one second locking portion 15 extending toward the outside of the frame opening 11, the at least one second locking portion 15 is used for at least one fastener 20 to pass through to connect to the wall Face 3, easy to assemble and good stability. With reference to Fig. 3 and Fig. 4, each of the second locking parts 15 is plate-shaped and extends obliquely relative to an opening direction of the frame opening 11; in detail, at least one of the two frames 10 further includes at least two cutouts. Groove 16, each of the second locking portion 15 includes a bending section 151 and a locking section 152 connected to the bending section 151, each of the opposite sides of the bending section 151 is respectively provided with a gap 16 , so that each of the bending sections 151 is easy to bend to adjust an inclination angle of the locking section 152 to meet different usage requirements. An angle θ is defined between the extending direction of the locking section 152 of each of the second locking parts 15 and the width direction W, and the angle θ is not greater than 90 degrees, whereby the second locking parts 15 can The inner wall of the opening to be fixed on the wall 3 will not protrude from the opening, as shown in Figure 6 and Figure 7, which has good aesthetics.

Each of the first locking parts 12 and each of the second locking parts 15 respectively includes a screw hole, a round hole or an elongated hole; each of the at least one first locking part 12 and the at least one second locking part of the frame 10 The locking parts 15 are located on the same side in the width direction W, and the opposite sides of each of the first locking parts 12 are respectively provided with a second locking part 15, so as to stably maintain the position of each of the first locking parts 12 To prevent displacement when a switch cover plate 4 is assembled. Preferably, the first arm portion 131 of at least one of the two frames 10 is provided with a second locking portion 15 capable of interfering with an end surface of the second arm portion 132 in the moving direction M and locking , so that the distance between the two frames 10 can be relatively close, and when each of the first arm portions 131 is locked on the inner side wall of the opening by the second locking portion 15, each of the second arm portions 132 Interposed between the first arm portion 131 and the switch box 2 , the assembly stability is good.

In use, the two frames 10 can be relatively close to be placed in the opening or/and the switch box 2, as shown in FIG. Connect to the inner side of the switch box 2, and lock the second locking parts 15 on the wall 3 with a plurality of fasteners 20, as shown in Figure 6, the switch cover can be further assembled 4. As shown in Figure 7, the operation is simple and the assembly stability is good.

Please also refer to the second preferred embodiment shown in FIGS. 8 to 10. In this embodiment, the extension lengths of the two arm portions 13a of each frame 10a are different, and the first arm portions of each frame 10a The extension length of 131a is greater than the extension length of the second arm portion 132a, so as to ensure that the guide parts 14a of the two frames 10a are misaligned and have better assembly stability; the guide parts 14a of each The plurality of blocking pieces 141a are at least partially disposed on two opposite sides of the frame 10a in the width direction W, so that each of the first arm portions 131a can slide along the moving direction M more smoothly.
