Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present application relates to a mounting column that mounts a column that supports a support arm that supports a telephone mounting table, for example, on a desk so as to be rotatable and axially connectable.

2. Description of the Related Art Conventionally, a mounting column having a supporting arm that supports a telephone mounting table or the like is rotatably mounted on a desk so as to be connectable in the axial direction. Is fitted to the fitting shaft or the fitting cylinder, and the support pipe and the fitting shaft or the fitting cylinder are attached by engaging the guide hole in the circumferential direction and the locking screw to rotate the shaft. It was configured to prevent slipping in the direction.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention According to the above-described conventional mounting column, a locking screw and a guide hole for rotatably mounting the column pipe to a desk or the like are exposed to the outside to significantly impair the posture, There are inconveniences such as the protrusion of the locking screw is an obstacle and the locking screw is easily loosened.

Means for Solving the Problems Therefore, the present application, in order to improve the inconvenience of the above, below the upper portion fixed to the lower inner circumference of the support pipe that supports the support arm, and fitted in the mounting pipe, and A hollow connecting cylinder integrally formed with a lower part formed on the lower surface on an inclined surface, and inserted into the connecting cylinder to lead out from the lower surface of the connecting cylinder, and a screw portion is formed on the derived lower part, and a pillar is provided on the upper end. A screw shaft having a head that can be rotated in the pipe, an upper inclined surface that is loosely fitted to the lead-out portion of the screw shaft, and that is joined to the inclined surface on the upper surface, and the upper inclined surface is on the lower surface. Locking pieces each having a lower inclined surface inclined in the opposite direction,
An interlocking column for a telephone mounting table or the like, which is equipped with a connecting member that is screwed into the threaded portion of the screw shaft and that has a nut formed on the upper surface with an inclined surface that joins with the lower inclined surface of the locking piece. And in the above,
The connecting tube is so that the mounting columns can be connected in the axial direction.
A strut is provided between an upper portion fixed to the inner surface of the lower portion of the strut pipe and a lower portion having an inclined surface formed on the lower surface, and the lower portion, the locking piece and the nut can be fitted into the strut pipe, respectively. Preferably, the support pipe has an outer diameter, and the support pipe is rotatably attached to the outer periphery thereof through upper and lower spacing rings with a support arm provided in a cantilever shape on the outer side of the upper portion, and A rotation restricting means for restricting rotation of the outer cylinder is provided between the outer cylinder and the support pipe.

However, for example, in the case where the mounting column is erected on the mounting pipe buried in the corner of the desk, use a tool such as a screwdriver with the lower part of the connecting member fitted to the mounting pipe from above. Rotate the screw shaft from above the support pipe. Then, the nut also tries to rotate together with the screw shaft, but the inclined surface of the nut abuts the lower inclined surface of the locking piece and the rotation of the nut is restricted. It is sandwiched between the inclined surface of the connecting cylinder and the inclined surface of the nut, and if the screw shaft continues to rotate, the locking piece will
It receives a component force in the direction of inclination due to the connection with each inclined surface of the connecting tube and nut, and slides sideways, and the side surface of the locking piece presses against the inner surface of the mounting pipe, which causes the support pipe to pass through the connecting member. Fixed to the mounting pipe. And in the above, the connecting cylinder, the upper portion fixed to the inner surface of the lower portion of the strut pipe,
When a flange is provided between the lower part having a slanted surface on the lower surface, and the lower part, the locking piece and the nut each have an outer diameter capable of being fitted in the strut pipe, By the same action, the support pipes can be sequentially connected in the axial direction.

Embodiments Embodiments of the present invention will be described in detail below with reference to the drawings. A is for mounting the support pillar of the present application, for example, on the outside of the support pipe (2) having an inner diameter substantially equal to that of the mounting pipe (1) embedded in the corner of the desk board B of the desk, and on the side of the upper end of the telephone mounting base. An outer cylinder body (5) having a support arm (4) supporting (3) mounted in a cantilever shape is attached to a pair of upper and lower spacing rings (6) a,
(6) Shows a support member that is rotatably fitted by b, and the rotation of the support pipe (2) and the outer cylinder body (5) is
It is regulated by the engagement between the head of the screw (7) provided on the strut pipe (2) and the engaging projection (8) protruding from the inner surface of the outer tubular body (5). The upper gap holding ring (6) a has a stepped notch (9) on the outer peripheral edge of the upper surface, and the lower gap holding ring (6) b has a stepped notch on the inner peripheral edge of the lower surface.

Is a collar part (1) that fits into the hollow part (10) on the outer periphery of the intermediate part.
2), the upper portion of the collar portion (12) is fitted into the lower end portion of the strut pipe (2) by press fitting or welding, and the lower portion of the collar portion (12) is the mounting pipe (1). )
A hollow connecting cylinder (14) having an outer diameter that fits in the lower surface and an inclined surface (13) formed on the lower surface, and the head contacts the upper surface of the connecting cylinder (14) through a washer (15). A screw shaft (17) having a threaded portion (16) provided in the lower portion of the lead-out portion while the contact portion is inserted into the connecting cylinder (14) and the lower portion is led out from the inclined surface (13). And has a through hole (18) in which the lead-out portion of the screw shaft (17) is loosely fitted, and is joined to the inclined surface of the connecting cylinder (14) on its upper surface. A locking piece (2) having an upper inclined surface (19) and a lower inclined surface (20) inclined in the opposite direction to the above inclined surface on the lower surface.
1) and a short shaft body, the threaded portion (16) of the screw shaft (17) is screwed into the shaft core portion, and the inclined surface (20) of the locking piece (21) is attached to the upper surface. It is composed of a nut (23) having an inclined surface (22) to be joined, and at the lower end of the screw shaft (17), a bulging portion (2) for preventing the nut (23) from slipping off.
4) is provided. Reference numeral (25) denotes a cap fitted to the upper ends of the support pipe (1) and the mounting pipe (2), and the notch (9) of the upper gap holding ring (6) a is provided on the lower surface of the disk-shaped top. ) To a peripheral rib (26) fitted to the upper outer peripheral edge of the mounting pipe (1) and a fitting rib (27) fitted to the inner circumference of the upper end of the support pipe (2) to the mounting pipe (1).
