Technical Field

[0001] The utility model relates to the technical field of torsion spring installation, in particular to a torsion spring assembly tool. Background Art

[0002] A torsion spring assembly tool is a tool used to install torsion springs on seat backs. A torsion spring is a spring used to provide support and comfort to the seat back. The function of a torsion spring assembly tool is to help correctly install the torsion spring in the corresponding position of the seat back. It usually has a special design and shape to easily fix the torsion spring in the correct position to ensure the stability and comfort of the seat back. The torsion spring assembly tool can improve assembly efficiency and reduce the possibility of errors or damage during installation.

[0003] In the prior art, for the installation of the seat back, employees generally use a screwdriver or a pry bar to determine the installation position and direction of the torsion spring, insert the narrower end of the torsion spring into the corresponding hole of the seat back, ensure that the annular portion of the torsion spring faces the correct direction, use the pry bar or the flat head of the screwdriver to insert it into the annular portion of the torsion spring, and apply appropriate pressure downward, while using the other hand to push the wider annular portion of the torsion spring into the hole of the seat back until the torsion spring is fully installed. However, when using a screwdriver or a pry bar for installation, since the end of the torsion spring and the surface of the screwdriver or the pry bar are sliding, one end of the screwdriver or the pry bar is used as a fulcrum to tilt the end of the torsion spring and then install it toward the inside of the seat, and the fulcrum end of the screwdriver or the pry bar or the end of the torsion spring installed is very easy to slip off. If one of them slips off, it is very easy to cause injury to the installer, increasing the risk of torsion spring installation, and also reducing the efficiency of torsion spring installation.

[0016] The following is a detailed description of the present invention in conjunction with the accompanying drawings and specific embodiments. Before describing in detail the technical solutions of each embodiment of the present invention, the nouns and terms involved are explained. In this specification, components with the same name or the same number represent similar or identical structures and are only for illustrative purposes.

[0017] like Figure 1-Figure 3 As shown, a torsion spring assembly tool comprises a main rod 10 and an assembly rod 20 installed at least at one end of the main rod 10, wherein the assembly rod 20 comprises a rod body 201 installed at the end of the main rod 10 and a clamping hole 202 opened at the end of the rod body 201 away from the main rod 10, the end of the torsion spring is clamped into the clamping hole 202 and is moved along with the clamping hole 202, wherein the number of the assembly rods 20 is preferably two, which are respectively located at the two ends of the main rod 10, and the rod body 201 is installed at the end of the main rod 10, By inserting the clamping hole 202 into the end of the torsion spring and applying force through the rod body 201 at the other end of the main rod 10, the clamping hole 202 limits the torsion spring, and the torsion spring can rotate in the clamping hole 202. By moving the rod body 201 at one end, the rod body 201 at the other end of the main rod 10 is driven to install the torsion spring in the car seat accordingly, avoiding the use of a screwdriver or a pry bar to slide on the surface of the torsion spring, which causes the torsion spring to easily slip from the surface of the screwdriver or the pry bar, thereby avoiding personal injury.

[0018] Embodiment 1:

[0019] The rod body 201 and the main rod 10 can be adjusted and fixed. The rod body 201 and the main rod 10 can be slid through each other. The rod body 201 and the main rod 10 are vertically arranged. The rod body 201 and the main rod 10 slide back and forth. The position between the rod body 201 and the main rod 10 can be fixed by bolt tightening, pin fixing and other similar methods, which is convenient for adjusting the position between the rod body 201 and the main rod 10 to adapt to different car seat adjustment uses.

[0020] Embodiment 2:

[0021] The rod body 201 is fixedly connected to the main rod 10 . The rod body 201 and the main rod 10 are integrally formed, or welded, to ensure the stability of the connection between the rod body 201 and the main rod 10 .

[0022] Embodiment three:

[0023] On the basis of Example 1 or Example 2, in order to improve the convenience of using the tool, the rod body 201 at one end of the main rod 10 can be set to extend out of one side of the main rod 10, and only the clamping hole 202 at one end of the rod body 201 is used to move the torsion spring, so as to avoid the distance that the other end of the rod body 201 extends from the main rod 10 affecting the interference with the car seat during the assembly process. The rod body 201 can be slidably adjustable with the main rod 10, that is, the installation method adopts the above-mentioned Example 1; the rod body 201 can be fixedly installed with the main rod 10, and can be welded or integrally formed, that is, the installation method adopts the above-mentioned Example 2.

[0024] like Figure 2 and Figure 3 As shown, the axial direction of the clamping hole 202 is arranged parallel to the main rod 10, so that when personnel use the main rod 10 to adjust the end of the torsion spring, the inclination angle of the main rod 10 is consistent with the toggling angle of the torsion spring.

[0025] like Figure 2 and Figure 3 As shown, the clamping hole 202 is in the shape of a water drop, and the arc-shaped part of the water drop is used to clamp the end of the torsion spring, and the tail end of the water drop is an open part, that is, the torsion spring enters the arc-shaped part from the open part of the clamping hole 202, which can play a role in moving the torsion spring; in addition to the water drop shape, the clamping hole 202 can also adopt other shapes, such as square holes, angular holes, triangular holes, and fan-shaped holes, and their corners are all rounded.

[0026] like Figure 3 As shown, a hand-held rod 30 is installed in the middle of the main rod 10, and the hand-held rod 30 can be conveniently held by people to improve the force effect of the hand on the torsion spring. Among them, the hand-held rod 30 can adopt the connection method between the rod body 201 and the main rod 10 in the above-mentioned embodiment one or embodiment two.

[0027] When in use, first move the rod body 201 at one end of the main rod 10 to the side where the torsion spring needs to be installed, then place the end of the torsion spring in the clamping hole 202, and rotate and adjust the main rod 10, the hand-held rod 30 or the rod body 201 at the other end until the installation end of the torsion spring is clamped into the car seat as the rod body 201 is adjusted. This can achieve the installation of the torsion spring, avoiding the use of a screwdriver or pry bar to slide on the surface of the torsion spring, which causes the torsion spring to easily slip from the surface of the screwdriver or pry bar, thereby avoiding personal injury.
