[0019] The specific embodiments of the utility model are further described below. It should be understood that the description of the utility model herein is not used to limit the protection scope of the utility model.

[0020] As Figures 1 to 2As shown, it is a structure schematic view of the buckle beneficial to improve the durability provided by the first embodiment of the utility model. The buckle beneficial to improve the durability includes a plate fixed part 10 and a contraction part 20 fixed on the plate fixed part 10. It is conceived that the buckle beneficial to improve the durability should also include some other functional components, such as a base for fixing the buckle beneficial to improve the durability and a sheet metal part clamped in the buckle beneficial to improve the durability, etc., which are prior art known by those skilled in the art and will not be described here.

[0021] The plate fixed part 10 is used for clamping and fixing a plate, such as a sheet metal part, etc. The plate fixed part 10 includes a fixed main body 11 and two abutting blocks 12 fixed on the fixed main body 11.

[0022] The fixed main body 11 is in U-shaped structure, thereby facilitating the insertion of the sheet metal part to be fixed into the fixed main body 11.

[0023] The two abutting blocks 12 are located at one end of the opening end of the fixed part main body 11 and are symmetrically arranged on both sides of the U-shaped fixed main body 11. The cross section of the abutting block 12 can be arranged in a trapezoidal shape. One side of the long bottom edge of the trapezoid is fixedly connected with the fixed part main body 11 to ensure the connection strength between the abutting block 12 and the fixed part main body 11. When the sheet metal part is clamped and fixed in the fixed main body 11, one side of the trapezoidal short edge of the two abutting blocks 12 abuts against the two sides of the sheet metal part respectively, thereby fixing the sheet metal part.

[0024] The contraction part 20 includes two contraction main bodies 21 fixedly connected on both sides of the fixed main body 11, two limiting blocks 22 arranged on the free end of the contraction main body 21 respectively, and two limiting openings 23 located on one side of the limiting block 22 respectively.

[0025] The two contraction main bodies 21 are inclinedly arranged in an inverted "eight" shape on the fixed main body 11 and form an A-shaped structure with the fixed part main body 11. Specifically, the included angle between the contraction main body 21 and the fixed part main body 11 can be adjusted according to the size of the buckle beneficial to improve the durability and the thickness and clamping force of the fixed sheet metal part. When the clamped sheet metal part is thicker and easier to clamp, the contraction main body 21 only needs to be slightly contracted to make the abutting block 12 clamp the sheet metal part placed in the fixed main body 11, so the included angle between the contraction main body 21 and the fixed main body 11 can be about 5-15 degrees, such as 10 degrees. Figure 1When the clamped sheet metal part is thin or the required clamping force is large, the included angle between the contraction body 21 and the fixed body 11 can be appropriately increased, for example, to about 15-45 degrees. Figure 2 The included angle between the contraction body 21 and the fixed body 11 is adjusted according to the clamping requirement, so that the deformation of the buckle for improving the durability is small when clamping, thereby increasing the durability of the buckle for improving the durability. When the buckle for improving the durability is used, the plate to be fixed is first inserted into the fixed body 11, and then the buckle for improving the durability is inserted into the clamping groove of the fixed base (not shown) for fixing the buckle for improving the durability from one end of the fixed body 11. The clamping groove can be a rectangular clamping groove suitable for the size of the buckle for improving the durability. During the insertion of the buckle for improving the durability into the clamping groove, the contraction body 21 and the fixed body 11 are inclinedly arranged, and the distance between the two contraction bodies 21 is greater than the width of the clamping groove, so that the clamping groove can squeeze the contraction body 21 to contract during the insertion, thereby driving the fixed body 11 to contract, so that the two abutting blocks 12 can abut against the plate placed in the fixed body 11 from both sides.

[0026] The limiting block 22 is fixedly arranged at the free end of the contraction body 21. When the buckle for improving the durability is inserted and fixed in the clamping groove of the fixed base, the limiting block 22 is used to prevent the buckle for improving the durability from slipping out of the clamping groove of the base.

[0027] The limiting opening 23 is arranged on the side of the limiting block 22 facing the plate fixing part 10, and the opening width thereof can be adapted to the thickness of the base for fixing the buckle for improving the durability. The limiting opening 23 is arranged obliquely on the side opposite to the limiting block 22, thereby forming a guide inclined surface, so that when the buckle for improving the durability is inserted into the clamping groove on the base, the clamping groove can be slidably arranged at the limiting opening 23 along the contraction body 21, thereby fixing the buckle for improving the durability.

[0028] Compared with the prior art, the buckle beneficial to improve the durability comprises a plate fixing portion 10 and a contraction portion 20 fixed on the plate fixing portion 10. The plate fixing portion 10 comprises a fixed main body 11 and two fixed top blocks 12 fixed on the fixed main body 11. The contraction portion 20 comprises two contraction main bodies 21 fixedly connected on the two sides of the fixed main body 11 respectively. The fixed main body 11 is in U-shaped structure. Compared with the A-shaped structure, the deformation and damage of the buckle in the opening and closing process are smaller. The two contraction main bodies 21 are inversely "eight" shaped and are inclinedly arranged on the fixed main body 11 and form A-shaped structure with the fixed main body 11, so that the opening width of the locking portion 20 is greater than that of the fixed main body 11, so that the buckle beneficial to improve the durability can clamp the plate fixed on the fixed main body 11 only by a small contraction distance, thereby improving the durability of the buckle beneficial to improve the durability.

[0029] As shown in Figure 3 , it is a structure schematic view of a buckle beneficial to improve the durability provided by the second embodiment of the utility model. The buckle beneficial to improve the durability comprises a contraction portion 30 and a plate fixing portion 40 fixedly arranged in the inside of the contraction portion 30.

[0030] The contraction portion 30 comprises a contraction main body 31, two limiting blocks 32 arranged on one end of the contraction main body 31 and two limiting openings 33 arranged on the two sides of the main body 31 respectively.

[0031] The contraction main body 31 is in A-shaped structure. The opening distance of the opening end of the A-shaped structure of the contraction main body 31 is greater than the width of the clamping groove for fixing the buckle beneficial to improve the durability. When the buckle beneficial to improve the durability is used, the contraction main body 31 is inserted into the clamping groove of the fixed base from the closed end of the A-shaped structure. Under the extrusion of the clamping groove, the opening end of the contraction main body 31 is contracted, that is, the opening angle of the contraction main body 31 is smaller, so that the plate fixing portion 40 fixed on the contraction main body 31 can be closed to clamp the plate arranged in the plate fixing portion 40.

[0032] The limiting blocks 32 are arranged at the end of the opening end of the contraction main body 31, and when the buckle beneficial to improve the durability is inserted into the clamping groove of the base, the limiting blocks 32 are used for preventing the buckle beneficial to improve the durability from slipping out of the clamping groove.

[0033] The two limiting ports 33 are respectively located on one side of the two limiting blocks 32. The limiting ports 33 are inclined on the side opposite to the limiting blocks 32, thereby forming an inlet slope. When the buckle that improves durability is inserted into the slot of the base, the side wall of the slot is engaged in the limiting port 33, thereby fixing the buckle that improves durability in the slot.

[0034] The plate fixing part 40 is located inside the shrink body 31 and includes two fixing bodies 41 symmetrically arranged on the shrink body 31, and two abutting blocks 42 respectively arranged on the fixing bodies 41.

[0035] The two fixing bodies 41 are respectively spaced apart on both sides of the shrinking body 31, thereby forming a U-shaped clamping groove between the two fixing bodies 41 to accommodate the sheet metal parts.

[0036] The abutment block 42 is located on one side opposite to the two fixed bodies 41, which further reduces the distance between the two fixed bodies 41, so that the shrinking body 31 can compress the two abutment blocks 42 together with only a small amount of shrinkage, thereby forming a strong clamping force on the sheet metal part.

[0037] like Figures 4 to 5 The diagram shown is a structural schematic of a buckle that improves durability according to the third embodiment of this utility model. The buckle that improves durability includes a shrinkable portion 30 and a plate fixing portion 60 fixedly disposed inside the shrinkable portion 30.

[0038] The contraction section 50 also has an A-shaped structure, and its function and principle are the same as those of the contraction section 30, so it will not be described in detail here.

[0039] The plate fixing part 60 is located inside the shrinking part 50, and includes two positioning parts 61 fixedly disposed on one side of the closed end of the shrinking part 50, and two clamping parts 62 disposed on one side of the open end of the shrinking part 50 corresponding to the positioning parts 61.

[0040] The positioning portions 61 are spaced apart on the contraction portion 50, forming a U-shaped groove between the two positioning portions 61 to facilitate the positioning and accommodating of the sheet metal part. An arc-shaped protrusion 611 is also provided on each of the two positioning portions 61 on opposite sides. The arc-shaped protrusion 611 significantly reduces the contact area between the positioning portion 61 and the sheet metal part compared to planar contact when the durable-enhancing buckle is in the clamping state, thereby increasing the clamping force of the positioning portion 61 on the sheet metal part. Figure 5As shown, one side of the positioning part 61 can also be directly provided with an arc shape to achieve the same effect as the arc-shaped protrusion 611.

[0041] Two clamping parts 62 are correspondingly and spacedly arranged on one side of the opening end of the contraction part 50. The clamping part 62 comprises a clamping body 621 fixedly connected with the contraction part 50, and a stopper 622 arranged on the clamping body 621.

[0042] The two clamping bodies 621 are obliquely arranged on the contraction part 50 and have an outer "8" structure. The two stoppers 622 are symmetrically arranged on opposite sides of the two clamping bodies 621. When the buckle facilitating the improvement of durability is used, the contraction part 50 is inserted into the clamping groove of the base, so that the contraction part 50 is contracted, thereby driving the two clamping parts 62 to approach each other until the stopper 622 fixes and clamps the metal plate inserted into the positioning part 61, at this time, the arc-shaped protrusion 611 further extrudes the metal plate. Therefore, the plate fixing part 60 can constitute double fixation to the plate.

[0043] The above is only a preferred embodiment of the present application, and is not used to limit the protection scope of the present application. Any modification, equivalent replacement or improvement within the spirit of the present application is covered within the protection scope of the present application.
