[0023] like Figure 1-4As shown, this utility model provides a technical solution: a car body component assembly and fixing fixture, comprising: a support frame 1, a sliding groove adapted to a pull block 41 is provided on one side of the support frame 1, one end of a connecting rod 46 slides through one side of the inner wall of the sliding groove, the pull block 41 can move normally on the support frame 1 by providing the sliding groove, a fixture body 2 is provided on one side of the support frame 1, a swing rod 3 is movably connected to one side of the fixture body 2 via a rotating shaft, a limiting mechanism 4 is provided inside the support frame 1, the limiting mechanism 4 includes a pull block 41 that slides through one side of the support frame 1, a rotating rod 43 is fixedly connected to one end of the swing rod 3, one end of the rotating rod 43 movably passes through one side of the support frame 1 via a bearing, a movable groove adapted to a top block 44 is provided inside the support frame 1, the top block 44 can rotate normally inside the support frame 1 by providing the movable groove, one end of the rotating rod 43 is fixedly connected to the top block 44, and one side of the top block 44 is glued An anti-slip pad 45 is provided. A connecting rod 46 is fixedly connected to one side of the pull block 41. A spring 47 is sleeved on the outer surface of the connecting rod 46. One end of the spring 47 is welded to one side of the inner wall of the movable groove inside the support frame 1, and the other end of the spring 47 is welded to one side of the fixed plate 48. By setting the spring 47, the spring 47 provides sufficient elastic force so that the fixed plate 48 can actively return to its original position with the help of the elastic force of the spring 47. One end of the connecting rod 46 is fixedly connected to the fixed plate 48. A protrusion 49 is provided on one side of the fixed plate 48. The outer surface of the protrusion 49 contacts the outer surface of the anti-slip pad 45. By setting the protrusion 49 and the anti-slip pad 45, the contact between the protrusion 49 and the anti-slip pad 45 increases the friction between the fixed plate 48 and the top block 44, so that the top block 44 can be positioned within the support frame 1 with the help of the fixed plate 48, the anti-slip pad 45, and the protrusion 49. A fixing mechanism 42 is provided inside the support frame 1.

[0024] Example 2

[0025] like Figure 3-4As shown, the fixing mechanism 42 includes a locking plate 421 that slides through one side of the support frame 1. A sliding rod 422 is fixedly connected inside the fixing plate 48. A tension spring 423 is sleeved on the outer surface of the sliding rod 422. One end of the tension spring 423 is welded to one side of the inner wall of the limiting groove inside the locking plate 421, and the other end of the tension spring 423 is welded to one side of the limiting plate 424. By setting the tension spring 423, the tension spring 423 provides sufficient tension, so that the locking plate 421 can actively move out of the fixing plate 48 with the help of the tension of the tension spring 423. One end of 22 is fixedly connected to a limiting plate 424. A groove adapted to the clamping plate 421 is provided on one side of the fixing plate 48. By providing the groove, the clamping plate 421 can move normally into the fixing plate 48. A sliding hole adapted to the sliding rod 422 is provided on one side of the clamping plate 421, and a limiting groove adapted to the limiting plate 424 is provided on the other side of the clamping plate 421.

[0026] Working principle:

[0027] like Figure 1-4 As shown, during use, the clamp body 2 is adjusted according to the width of the car door, pushing the clamping plate 421 to move. The clamping plate 421 gradually moves out of the support frame 1 and gradually moves into the fixing plate 48. The clamping plate 421 slides on the outer surface of the slide rod 422 and the limiting plate 424. The tension spring 423 is affected by the thrust, and its shape gradually changes until it pushes the clamping plate 421 to move. When the fixing plate 48 is fixed inside the support frame 1, the spring 47 is in a state of deformation. When the fixing plate 48 is released from the fixing restriction, the spring 47 is no longer affected by the force, and its shape gradually returns to its original state. In the process of shape recovery, it drives the fixing plate 48 to move. The protrusion 49 follows the fixing plate 48. The movement disengages from the anti-slip pad 45 on the top block 44, the swing arm 3 releases its limit restriction, the swing arm 3 adjusts the position of the clamp body 2, and after the clamp body 2 opens to the appropriate degree, the position of the swing arm 3 remains unchanged, and the pull block 41 is pulled to move. During the movement of the pull block 41, the connecting rod 46 is moved, and during the movement of the connecting rod 46, the fixing plate 48 is moved. The protrusion 49 contacts the anti-slip pad 45 on the top block 44 again until the pull block 41 can no longer move. The clamping plate 421 actively moves out of the fixing plate 48 with the help of the tension spring 423 and inserts into the support frame 1 to fix the fixing plate 48. The swing arm 3 is limited again, and the door to be assembled is placed on the clamp body 2 for fixing.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
