[0001] This application relates to the field of removing localized deformation of metal, specifically to a stepless adjustable sheet metal repair tensioner. Background Technology

[0002] Sheet metal repair tensioners, widely used in automotive repair, metal processing, and other fields, function primarily to apply precise tension to deformed sheet metal parts through an adjustable traction mechanism to restore their original shape. In existing technologies, single-point and double-leg sheet metal repair tensioners often employ an arc-shaped groove combined with a positioning pin to adjust the tension angle. Specifically, the operator inserts the positioning pin into a pre-set hole or groove on the arc-shaped groove to fix the traction arm or support leg in a specific position.

[0003] The arc-shaped grooves need to be set at intervals, which limits the adjustment accuracy to the preset hole spacing, making it impossible to achieve stepless continuous adjustment and making it difficult to fine-tune the position of the traction arm or support, thus affecting the repair.

[0032] Example 1

[0033] See attached document Figure 1-6 As shown in the embodiment of this application, the continuously adjustable sheet metal repair tensioner of this embodiment includes:

[0034] The first connector 10 is provided with a strip groove 11 arranged along its length direction;

[0035] The second connector 20 has a sliding hole 21 and is sleeved on the first connector 10 through the sliding hole 21. The second connector 20 has an elastic locking arm 22 that extends into the strip groove 11 on the inner wall of the sliding hole 21.

[0036] A locking member 30 is installed on the second connector 20 and extends into the sliding hole 21. The locking member 30 can move on the second connector 20 to push the elastic locking arm 22 against the inner wall of the strip groove 11 to lock the second connector 20 onto the first connector 10, or move away from the elastic locking arm 22. The elastic locking arm 22 is released from the strip groove 11 so that the second connector 20 can slide along the length direction of the first connector 10.

[0037] In this embodiment, the continuously adjustable sheet metal repair tensioner is a double-leg sheet metal repair tensioner. The first connecting member 10 is a support beam, and the second connecting member 20 is a support leg. A pulling assembly 50 is installed on the support beam. Two support legs are sleeved on the support beam and are located on both sides of the pulling assembly 50. An abutment seat 40 is hinged to the end of each support leg.

[0038] When using the stepless adjustable sheet metal repair tensioner described in this embodiment, after connecting the pulling assembly 50 to the sheet metal surface to be repaired, move the locking member 30 away from the elastic locking arm 22. The elastic locking arm 22 is then released from locking, and the support leg can slide along the support beam to adjust the position of the two support legs. After adjusting the position of the support leg so that the support leg 60 is supported on the support plane, move the locking member 30 to push the elastic locking arm 22 against the inner wall of the strip groove 11 and lock the support leg on the support beam. This achieves stepless adjustment of the position of the support leg, allowing for fine-tuning of the position of the support leg and making it more convenient to use.

[0039] In one embodiment, the elastic locking arm 22 includes a locking arm mounted on the support member by an elastic element and located in the strip groove 11. In this embodiment, the elastic locking arm 22 is made of plastic so that the elastic locking arm 22 can be elastically deformed by the approach of the locking member 30 and then abut against and lock against the inner wall of the strip groove 11. After the locking member 30 moves away, the elastic locking arm 22 can return to its initial state and be released from locking with the first connecting member 10.

[0040] Based on the above, in this embodiment, the support leg is made of plastic, and the elastic locking arm 22 is integrally formed with the support leg, which facilitates production. At the same time, the use of plastic for the support leg can reduce the overall weight of the tensioner.

[0041] In one embodiment, a through hole is provided on the side wall of the support beam for the locking member 30 to pass through and extend into the strip groove 11, so that the locking member 30 extends into the interior of the strip groove 11 from the groove wall. Two elastic locking arms 22 are provided, and the locking member 30 is disposed between the two elastic locking arms 22. The locking member 30 moves and extends between the two elastic locking arms 22 to push the two elastic locking arms 22 away from each other and abut against the inner wall of the strip groove 11 to lock them, or moves away from the two elastic locking arms 22 to release the two elastic locking arms 22 from the inner wall of the strip groove 11.

[0042] Based on the above, the two elastic locking arms 22 are respectively provided with inclined surfaces 23 on the side that are close to each other, and the two inclined surfaces 23 are inclined in the direction that are close to each other on the side that is away from the groove opening of the strip groove 11. When the locking member 30 is gradually moved into the space between the two elastic locking arms 22, the locking member 30 pushes the two elastic locking arms 22 against the inner wall of the strip groove 11 through the inclined surfaces 23 and locks them.

[0043] In this embodiment, the inner wall of the strip groove 11 is provided with a slot 12, and the elastic locking arm 22 has a locking block 24 extending into the slot 12, and there is a gap between the locking block 24 and the inner wall of the slot 12, so as to ensure that the elastic locking arm 22 is locked with the slot 12 under the push of the locking member 30. As a preferred embodiment, the slots 12 are respectively provided on opposite sides of the inner wall of the strip groove 11.

[0044] In this embodiment, the locking member 30 is a bolt, and the second connecting member 20 is provided with a threaded hole. The locking member 30 is screwed into the threaded hole and extends into the strip groove 11. Tightening the locking member 30 causes it to move in the direction of entering the strip groove 11 and extend between the two elastic locking arms 22, pushing the two elastic locking arms 22 away from each other. Loosening the locking member 30 causes it to move out of the strip groove 11, and the two elastic locking arms 22 return to their initial state.

[0045] In another embodiment, the locking member 30 can also be a rod connected to the support member via an elastic member. The rod extends between the two elastic locking arms 22 under the action of the elastic member and locks the elastic locking arms 22 with the locking groove 12. The locking member 30 can move away from the two elastic locking arms 22 under the action of external force to release the locking arms 22 from the locking groove 12, so that the support beam and the support member can slide relative to each other to the adjusted position. After the external force is removed, the locking member 30 returns to the two elastic locking arms 22 under the action of the restoring force of the elastic member, locking the elastic locking arms 22 with the locking groove 12.

[0046] In this embodiment, the end of the support member is provided with two support feet 60, and each support foot 60 is hinged with the abutment seat 40. When the sheet metal repair tensioner is used, it can abut against the support plane through the four abutment seats 40 respectively, which is suitable for different repair surfaces.

[0047] Preferably, the support leg is omnidirectionally connected to the abutment seat 40, so that the abutment seat 40 can be flipped relative to the support leg while also rotating circumferentially relative to the support leg, making the adjustment more flexible.

[0048] Specifically, the support leg is provided with a ball head 261, and the abutment seat 40 is provided with a ball head groove. The ball head 261 is disposed in the ball head groove to realize the universal connection between the support leg and the abutment seat 40.

[0049] Preferably, the abutment seat 40 is provided with a strip-shaped hole 422 communicating with the ball head groove, and the ball head 261 extends into the ball head groove after passing through the strip-shaped hole 422. Referring to the accompanying drawings, the support member can move along its length direction within the strip-shaped hole 422 to realize the flipping of the abutment seat 40, and can move along the width direction of the strip-shaped hole 422 to realize the circumferential rotation of the abutment seat 40. By designing the strip-shaped hole 422, the hole wall of the strip-shaped hole 422 can limit the swinging or excessive wobble of the support member relative to the abutment seat 40 (i.e., the swinging or excessive wobble of the pulling member occurs).

[0050] In this embodiment, the support leg includes a support body 25 and a ball joint 26. The ball joint 26 includes a ball head 261 and a connecting portion 262, which is detachably connected to the support body 25. Specifically, one end of the support body 25 is provided with a nut, and the connecting portion 262 is provided with a threaded post, which is fastened to the nut.

[0051] Based on the structure of the aforementioned support member, the abutment seat 40 includes a base 41 and a fixing block 42. The upper end of the base 41 is provided with a first groove 411. The fixing block 42 is detachably installed on the base 41, and its lower end is provided with a second groove 421. The second groove 421 and the first groove 411 surround each other to form the ball head groove. After the connecting part 262 passes through the strip hole 422 and connects to the support member body, the fixing block 42 is then installed on the abutment seat 40 to realize the assembly of the abutment seat 40 and the support member.

[0052] In this embodiment, the base 41 and the fixing block 42 are fastened together by fasteners. Specifically, the base 41 is provided with a light hole 412 that passes through it, and the second fixing block 42 is provided with a threaded hole 423 corresponding to the light hole 412. After the fastener 43 passes through the light hole 412, it is tightened into the threaded hole 423 to realize the detachable connection between the base 41 and the fixing block 42.

[0053] The abutment seat 40 is fitted with an anti-slip sleeve 44, which reduces the probability of the abutment seat 40 sliding on the abutment plane when it abuts against the abutment plane; it can also block the light hole 412 and the fastener 43, improving the appearance.

[0054] To facilitate the alignment of the aperture 412 and the threaded hole 423, the fixing block 42 is provided with two positioning blocks 424, and the base 41 is provided with two positioning holes 413. The two positioning blocks 424 are respectively inserted into the positioning holes 413, so that when the fixing block 42 and the base 41 are assembled, the aperture 412 and the threaded hole 423 are aligned with the positioning blocks 424 and the positioning holes 413, which facilitates the assembly of the fixing block 42 and the base 41.

[0055] Example 2

[0056] Unlike Embodiment 1, in this embodiment, the first connector 10 is a handle, the second connector 20 is a pull assembly, and the end of the first connector 10 is also hinged with an abutment seat 40.

[0057] When using the sheet metal repair puller described in this embodiment, the pull assembly 50 is connected to the sheet metal repair surface. The handle and the pull assembly are unlocked so that the handle and the pull assembly 50 can slide relative to each other to adjust the position of the handle so that the abutment seat 40 abuts against the support plane. Then the handle and the pull assembly are locked together.

[0058] In this embodiment, the first connector 10 and the abutment seat 40 can adopt the same structure as in embodiment 1.

[0059] Of course, this utility model is not limited to the above-described embodiments.
