[0001] The invention relates to the technical field of sheet metal repair tools, and in particular to a tensioner for sheet metal repair. Background Art

[0002] A tensioner is a tool specially used to repair dents in sheet metal (such as dents in sheet metal of automobile bodies, etc.), which restores the dented part of the sheet metal to its original state by physically pulling. In the existing technology, some tensioners include a support beam, two support legs, a pulling assembly, and two abutment seats, wherein the two abutment seats are connected to the two support legs one by one through a pivot rotation, and the abutment seats can be flipped relative to the corresponding support legs to adapt to abutting against the sheet metal surface (flat or curved surface). However, the inventors found in the market research and multiple tests of the above-mentioned tensioner that the abutment seat of the above-mentioned tensioner has a small degree of adjustability (can only be adjusted by rotating around the pivot axis), so the above-mentioned tensioner has the problem of being less applicable to sheet metal surfaces.

[0040] Reference Figures 1 to 8 An embodiment of the present invention provides a tensioner for sheet metal repair, which includes a support beam 100, a pulling assembly 200, a support leg 300 and an abutment seat 400.

[0041] The drawing assembly 200 is arranged on the support beam 100, and the drawing assembly 200 is used to draw the parts pre-arranged in the recessed place of the sheet metal. The support foot member 300 is provided with two, and the top end of the support foot member 300 is provided on the support beam 100. The two support foot members 300 are respectively arranged on both sides of the drawing assembly 200. The bottom end of the support foot member 300 is provided with a rod portion 811 and a ball head portion 812 connected and arranged up and down. The abutment seat 400 is provided with two, and the abutment seat 400 is provided with a connecting bar hole 421 and a ball head slot S1 arranged up and down. The two ball heads 812 are respectively rotatably arranged in the two ball head slots S1, and the ball head 812 can abut against the groove wall of the corresponding ball head slot S1 to limit the separation of the corresponding support foot member 300 and the corresponding abutment seat 400. The two rod portions 811 are respectively rotatably penetrated in the two bar holes 421, and the rod portions 811 can swing in the corresponding bar holes 421. Among them, the drawing assembly 200 is a prior art, so it is not described here.

[0042] It can be understood that the pulling assembly 200 is provided with a hook member 210 , and the pulling assembly 200 hooks and lifts the component pre-set in the recessed part of the sheet metal through the hook member 210 .

[0043] The process of restoring the depressed part of the sheet metal to its original state by pulling with a tensioner for sheet metal repair in the present application is as follows: 1. driving the two ball heads 812 to rotate in the two ball head slots S1 respectively, and the two rods 811 to swing in the two bar holes 421 respectively, so that the two abutment seats 400 are adaptively abutted against the sheet metal surface; 2. driving the pulling assembly 200 to hook up the component pre-set at the depressed part of the sheet metal, so that the depressed part of the sheet metal is deformed and restored to its original state under the action of the pulling force provided by the pulling assembly 200.

[0044] Through the above structure, on the one hand, the ball head 812 can rotate in the corresponding ball head slot S1, and the rod portion 811 can swing in the corresponding bar hole 421. In other words, the abutment seat 400 can be flipped relative to the corresponding support leg member 300 while it can still rotate relative to the corresponding support leg member 300. Therefore, compared with the traditional tensioner (the abutment seat of the traditional tensioner can only be flipped relative to the support leg member), the abutment seat 400 of the sheet metal repair tensioner of the present application is more adjustable and is suitable for more sheet metal surface conditions; on the other hand, in the process of driving the pulling assembly 200 to hook up the component pre-set in the sheet metal recess, the hole wall of the bar hole 421 can abut against the corresponding rod portion 811, so as to limit the swing or excessive deflection of the support leg member 300 relative to the abutment seat 400 (that is, the swing or excessive deflection of the pulling assembly 200), thereby ensuring the effect of deformation recovery at the sheet metal recess.

[0045] The abutting seat 400 includes a seat body 410 and a mounting block 420 .

[0046] Reference Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 as well as Figure 8 A groove 411 is provided on the top side of the seat body 100, and the mounting block 420 is detachably provided on the top side of the seat body 410. The mounting block 420 is provided with the above-mentioned strip holes 421 and the connecting holes 422 which are arranged in an upper and lower manner. The connecting holes 422 and the groove 411 together form the above-mentioned ball head groove S1. The ball head 812 can abut against the hole wall of the corresponding connecting hole 422 to limit the separation of the corresponding support leg member 300 and the corresponding abutment seat 400.

[0047] It can be understood that the seat body 410 is used to abut against a sheet metal surface.

[0048] Through the above structure, the seat body 410 and the mounting block 420 are disassembled and separated, so as to reduce the space occupied by the overall tensioner, and further reduce the transportation cost of the overall tensioner.

[0049] In this embodiment, refer to Figure 4The bottom of the groove 411 is provided with abutment blocks 500, and the two abutment blocks 500 are respectively abutted under the two ball heads 812. The abutment blocks 500 are made of elastic material.

[0050] Through the above structure, the abutment block 500 abuts against the bottom of the corresponding ball head 812. The abutment block 500 can provide a certain resistance when the corresponding ball head 812 moves, so as to reduce the situation where the abutment seat 400 flips and tilts toward the support leg 300 due to being too loose when the tensioner is moved.

[0051] The mounting block 420 is detachably disposed on the top side of the seat body 410. For details, refer to Figure 4 , Figure 6 as well as Figure 8 The top side of the seat body 410 is provided with a positioning groove 414 that cooperates with the mounting block 420, and the bottom of the positioning groove 414 is provided with the above-mentioned groove 411. The mounting block 420 is detachably inserted into the positioning groove 414 so that the groove 411 and the connecting hole 422 correspond.

[0052] Through the above structure, when the mounting block 420 is inserted into the positioning groove 414 , the groove 411 can correspond to the communicating hole 422 to jointly form the ball head groove S1 .

[0053] In this embodiment, refer to Figure 4 and Figure 6 A first hole 412 is provided at the bottom of the positioning groove 414, and the first hole 412 is a countersunk through hole. A second hole 423 is provided on the bottom side of the mounting block 420, and the second hole 423 is a threaded blind hole. A fastener 600 is passed through the first hole 412 and the second hole 423, and the fastener 600 is a bolt, wherein the fastener 600 can rotate to adjust the degree to which the mounting block 420 presses the ball head 812 against the abutment block 500 through the hole wall of the connecting hole 422; the first hole 412, the second hole 423 and the fastener 600 are all set to four.

[0054] Through the above structure, on the one hand, the seat body 410 and the mounting block 420 can be detachably connected; on the other hand, the degree to which the mounting block 420 presses the ball head 812 against the abutment block 500 through the hole wall of the connecting hole 422 can be adjusted, that is, the resistance provided by the abutment block 500 when the corresponding ball head 812 moves can be adjusted to meet the different requirements of different users.

[0055] In this embodiment, refer to Figure 2 , Figure 4 , Figure 5 as well as Figure 6 The seat body 410 is provided with an anti-skid cover 700 , and the anti-skid cover 700 blocks an opening of the first hole 412 that is connected to the outside, and the seat body 410 can abut against the sheet metal surface through the anti-skid cover 700 .

[0056] It can be understood that the other end opening of the first hole 412 which is a countersunk through hole corresponds to the second hole 423 which is a threaded blind hole, and one end opening needs to be connected to the outside for the fastener 600 to pass through and install.

[0057] Through the above structure, on the one hand, the seat body 410 can be abutted against the sheet metal surface through the anti-slip sleeve 700, so as to reduce the probability of the seat body 410 sliding on the sheet metal surface during the process of driving the pulling assembly 200 to hook up the component pre-set in the recessed part of the sheet metal; on the other hand, the first hole 412 is a countersunk through hole, and the second hole 423 is a threaded blind hole. The anti-slip sleeve 700 covers the end of the first hole 412 connected to the outside, that is, the fastener 600 is hidden, so as to prevent the user from observing the fastener 600, thereby improving the overall appearance of the tensioner.

[0058] In order to facilitate the positioning of the first hole 412 and the second hole 423, refer to Figure 6 and Figure 8 Two positioning blocks 424 are provided at the bottom side of the mounting block 420, and two positioning holes 413 are provided at the bottom of the positioning groove 414. The two positioning blocks 424 are respectively inserted into the positioning holes 413, so that the four first holes 412 and the four second holes 423 are arranged one by one.

[0059] In some embodiments, the positioning block 424 is disposed at the bottom of the positioning groove 414 , and the positioning hole 413 is disposed at the bottom side of the mounting block 420 .

[0060] In some embodiments, a positioning block 424 is provided at the bottom side of the mounting block 420 , and a positioning hole 413 is provided at the bottom of the positioning groove 414 .

[0061] In order to reduce the weight of the tensioner while ensuring the structural strength of the tensioner, refer to Figure 1 The seat body 410 and the support leg member 300 are integrally formed with a material-saving frame S2.

[0062] In some embodiments, only the abutment seat 400 is integrally formed with the material-saving frame S2.

[0063] The bottom end of the support leg 300 is provided with a rod portion 811 and a ball head 812 connected to each other. Figure 2 and Figure 6 , further comprising a connecting member 810, the connecting member 810 is provided with the above-mentioned rod portion 811 and the above-mentioned ball head portion 812, the bottom end portion of the foot member 300 is provided with a third hole 310, and the connecting member 810 is threadedly connected to the third hole 310 through the rod portion 811. Among them, the connecting member 810 is a ball head screw.

[0064] Through the above structure, the user can drive the connecting member 810 to rotate relative to the supporting leg member 300 according to the actual scenario to adjust the distance between the supporting leg member 300 and the abutting seat 400.

[0065] In this embodiment, refer to Figure 1 , Figure 2 , Figure 3 as well as Figure 5 The support beam 100 is provided with a plurality of locking notches 110 spaced apart along its length direction, a fourth hole 320, a fifth hole 330 and an opening 340 connecting the fourth hole 320 and the fifth hole 330 are provided at the top end of the support leg 300, the support leg 300 is slidably sleeved on the support beam 100 through the fourth hole 320, the fifth hole 330 is provided with a pressing piece 820 and an elastic piece, the elastic piece is a spring, the pressing piece 820 is provided with an avoidance notch 821, the hole wall of the fifth hole 330 is provided with a limiting groove 331, the pressing piece 820 is provided with a slidable limit groove 33 1, the elastic member abuts between the hole wall of the fifth hole 330 and the pressing member 820, the elastic member can drive the pressing member 820 to partially extend out of the fifth hole 330, and the pressing member 820 is inserted into a corresponding locking notch 110 through the opening 340 to limit the support leg member 300 from sliding along the length direction of the support beam 100, wherein pressing the portion of the pressing member 820 extending out of the fifth hole 330 can compress the elastic member and move the avoidance notch 821 to the opening 340, so that the support leg member 300 can slide along the length direction of the support beam 100.

[0066] It can be understood that the limiting block 822 can be slidably arranged in the limiting groove 331, and the groove wall of the limiting groove 331 can abut against the limiting block 822. On the one hand, it can prevent the elastic member from driving the pressing member 820 to completely escape from the fifth hole 330 to the outside; on the other hand, it can limit the distance that the pressing member 820 is driven to retract by pressing, so as to avoid the problem of damaging the elastic member due to excessive retraction of the pressing member 820.

[0067] It can be understood that the plurality of locking notches 110 are at least three locking notches 110 ; the portion of the pressing member 820 extending out of the fifth hole 330 is located outside.

[0068] Through the above structure, when the user presses the corresponding pressing piece 820 and drives the corresponding support leg piece 300 to slide along the length direction of the support beam 100 so that the two support leg pieces 300 have a suitable distance, the user can release the corresponding pressing piece 820 to allow the corresponding elastic piece to recover and drive the corresponding pressing piece 820 to partially extend out of the fifth hole 330 again, and allow the pressing piece 820 to be inserted into a corresponding locking notch 110 through the opening 340 to limit the support leg piece 300 from sliding along the length direction of the support beam 100 (i.e., lock the support leg piece 300 to the support beam 100).
