technical field

The invention relates to a fixing device, and in particular to a fixing device capable of fixing objects to objects of different sizes.

Background technique

The traditional way of fixing objects is mostly to use a rope or belt to pass through the object, attach the object to the target and then fasten the rope or belt to fix the object, because the length of the rope or belt is variable, so The target object can be a frame of a bicycle or other brackets with different sizes and shapes, and the application range is very wide. However, this fixing method often causes the object to fall because the rope body or the belt body is loose, and there is a problem that the object cannot be fastened for a long time. Therefore, some operators have developed a belt device, which utilizes the teeth on the belt to snap into the engaging portion to adjust the length of the belt so that it conforms to the size of the target object and then fixes the object. However, the belt device is a disposable item, and the teeth cannot be disengaged from the engaging portion after the fixed length, so the belt device must be cut off, causing inconvenience in use.

In addition, if the target object is the frame of a bicycle, because the bicycle is prone to shaking during riding, the belt device with limited bite force cannot be fastened to the frame, which may easily cause the object to fall off or shake accidentally The slack problem exists.

Then there is another kind of fixing device developed by the industry, which has a C-ring body and a screw lock device. The screw lock device connects the two ends of the C-ring, and the C-ring body can be pressed against the target by the action of the screw lock. In order to achieve the effect of fastening the object, this method can make the C-ring body continuously press the target object, so the fastening ability is strong, and it has the advantage that it is not easy to fall off in a shaking environment.

However, the fixed size of the C-ring body and the screw lock device of the above-mentioned fixing device is limited, so it cannot be applied to targets of various sizes, and the C-ring body is only suitable for tubular targets, once the shape of the target If it is changed, the fixed device will not work, and the diversity of use is still lacking. In addition, the screw lock device is not only heavy but also has too much metal locking force. If the tightening force of the screw lock device is too large when using the fixing device, the screw lock device may cause deformation and damage to the target or the C-ring body. If the tightening force of the screw lock device is too small, the problem of insufficient fastening capacity will easily occur, so there are still many inconveniences in use.

In view of this, how to increase the variety and convenience of the fastening device in use and make the fastening device have a good fastening ability has become the goal of the related industry.

Please refer to FIG. 4A and FIG. 4B, wherein FIG. 4A shows a schematic cross-sectional view of the action of the fixing device 100 of FIG. 1 applied to the target 110, and FIG. schematic diagram. When the knob 460 is moved along the axis I, it will drive the moving part 470 to move between the first position and the second position, as shown in Figure 4A, when the knob 460 is pulled up along the axis I, it will drive the moving part 470 to move up The engaging part 471 is engaged and fixed in the through hole 412 (see FIG. 2B ) and the through hole 421 (see FIG. 2B ), and drives the sun gear 441 to move along the axis I to separate from the planetary gear 442. At this time, the moving part 470 is located at the first Location. The ratchet arm 453 is separated from the second internal tooth 462 , so the ratchet arm 453 is not interfered by the knob 460 , that is, the ratchet arm 453 can rotate freely and the rotation of the bobbin 430 is not restricted.

Therefore, when the fixing device 100 is to be locked on the target object 110, the first end 310 can be separated from the protruding lip 280 first, and since the rotation of the bobbin 430 is not restricted at this time, the tension can be adjusted according to the size of the target object 110 Pieces 300 in length. Therefore, directly pull the first end 310 of the tension member 300 to rotate the spool 430 and release the tension member 300 , so that the length of the tension member 300 becomes longer to an appropriate length, and then surround the target 110 with the tension member 300 .
