[0007] In view of the defects in the prior art, the utility model provides a buckle to achieve the purpose of rapid assembly, improving assembly efficiency, and reducing labor intensity and labor costs.

[0008] The technical solution provided by the utility model is: a buckle, comprising a base plate, two clamping parts are arranged on the base plate, a first distance is arranged between the two clamping parts, and a protruding clamping block is arranged on one side of the two clamping parts away from each other;

[0009] The base plate is further provided with two limiting parts, the limiting parts are arranged in one-to-one correspondence with the clamping parts, and the limiting parts are arranged on the protruding side of the clamping block, the limiting parts extend to the bottom of the clamping block, and a second distance is arranged between the limiting parts and the clamping block;

[0010] The substrate is further provided with a positioning support portion arranged corresponding to the first spacing, the positioning sides of the positioning support portion are arranged on both sides of the clamping portion, and the arrangement direction of the positioning support portion is perpendicular to the arrangement direction of the clamping portion.

[0011] As an improvement, the clamping portion includes a vertical plate arranged in the width direction of the substrate and perpendicular to the substrate, and the clamping block is arranged at the end of the vertical plate and is arranged as a triangular protruding structure.

[0012] As a further improvement, the connecting end between the vertical plate and the base plate has a large thickness and gradually becomes thinner toward the clamping block.

[0013] As a further improvement, an arc-shaped connecting portion is provided between the vertical plate provided with the clamping block side and the base plate.

[0014] As an improvement, the limiting portion includes a limiting plate arranged in the width direction of the substrate and perpendicular to the substrate, and a bending portion is provided on the limiting plate.

[0019] By adopting the above-mentioned technical solution, the buckle provided by the utility model has the following beneficial effects:

[0020] Since the buckle includes a base plate, two clamping parts are arranged on the base plate, a first spacing is arranged between the two clamping parts, and a protruding clamping block is arranged on the side of the two clamping parts away from each other; two limiting parts are also arranged on the base plate, the limiting parts are arranged in a one-to-one correspondence with the clamping parts, and the limiting parts are arranged on the protruding side of the clamping block, the limiting parts extend to the bottom of the clamping block, and a second spacing is arranged between the limiting parts and the clamping block; the base plate is also provided with a positioning support part arranged corresponding to the first spacing, the positioning sides of the positioning support part are arranged on both sides of the clamping part, and the arrangement direction of the positioning support part is perpendicular to the arrangement direction of the clamping part Direction, based on the above structure, when the buckle is in use, the buckle is aligned with the clamping holes on the two parts to be connected, and at the same time, with the help of the first spacing, the clamping block on the clamping part is elastically deformed when passing through the two clamping holes, and resets after passing through, and completes the work of clamping into the clamping holes. At the same time, the limiting part also performs the limiting work, that is, the two parts to be connected are located between the clamping block and the limiting part, and the positioning support part will be positioned and matched with the inner walls of the two clamping holes, thereby realizing all-round (substrate height direction, width direction and length direction) positioning and matching, and the assembly effect of the two parts to be connected is good.

[0021] In summary, the use of this clip realizes the quick assembly of the two parts that need to be connected, simplifies the assembly process, has high assembly efficiency, does not require the aid of tooling, has high assembly accuracy, good positioning effect after assembly, and high positioning reliability. At the same time, it greatly reduces the labor intensity and cost of the staff.

[0022] Since the clamping part includes a vertical plate arranged in the width direction of the substrate and perpendicular to the substrate, the clamping block is arranged at the end of the vertical plate and is arranged as a triangular protruding structure; the connecting end of the vertical plate and the substrate has a large thickness and gradually becomes thinner toward the clamping block, so that the clamping is completed through the triangular protruding structure, and the elastic deformation and structural strength of the clamping part during clamping are ensured by the thickness change of the vertical plate.

[0023] Since an arc-shaped connecting portion is provided between the vertical plate provided with the clamping block side and the base plate, the problem of stress concentration and fracture at the connection between the vertical plate and the base plate can be avoided by the arc-shaped connecting portion.

[0024] Since the limiting portion includes a limiting plate arranged in the width direction of the substrate and perpendicular to the substrate, a bending portion is provided on the limiting plate, and the end of the bending portion is located below the clamping block and is provided with a second spacing, so that after clamping, the bending portion is abutted against the component to be connected, and the second spacing provides space for the elastic deformation of the bending portion.

[0025] Since the bent portion extends obliquely toward the bottom of the clamping block, it is beneficial to the reliability of the abutment and matching between the bent portion and the component to be connected.

[0026] Since the positioning support part includes a positioning plate arranged in the length direction of the substrate and located on both sides of the clamping part, inclined guide parts are provided at the two corners of the end of the positioning plate; a connecting reinforcement plate located within the first spacing is provided between the two positioning plates, so that the inclined guide part plays a guiding role when clamping into the clamping hole, the positioning plate is used to perform positioning cooperation with the clamping hole, and the structural strength of the two positioning plates during use is enhanced by the connecting reinforcement plate.

[0027] Since a through hole is provided on the substrate at a position corresponding to the first spacing, the connecting reinforcement plate extends into the through hole, thereby realizing connection among the connecting reinforcement plate, the substrate and the positioning plate, which helps to improve the structural strength of the positioning support part.

[0028] Since the base plate, the clamping part, the limiting part and the positioning support part are an integrally formed injection-molded part, they are easy to form, have high structural strength and are light in weight.

[0029] The utility model also provides a radiator to achieve the purpose of rapid assembly, improved assembly efficiency, reduced labor intensity and labor costs, and reduced overall weight of the radiator.

[0030] A radiator comprises a radiator body, a wind guide cover is arranged on one side of the radiator body, an upper water chamber and a lower water chamber are arranged at the top and the bottom of the radiator body respectively, a frame is arranged on both sides of the radiator body, a plurality of first clamping holes corresponding to each other are arranged on the side of the frame and the wind guide cover, the above-mentioned buckles are clamped in the two corresponding first clamping holes, when in the clamping state, the clamping block on the clamping part passes through the first clamping hole and abuts against the inner side surface of the frame, the positioning support part abuts against the inner wall of the first clamping hole, and the limiting part abuts against the wind guide cover;

[0031] The above-mentioned buckles are integrally formed at both ends of the upper water chamber and the lower water chamber, and a second clamping hole is provided on the frame at a position corresponding to the buckle. When in a clamped state, the thickness direction of the frame is clamped by the clamping block and the limiting portion on the clamping portion, and the positioning support portion rests on the inner wall of the second clamping hole.

[0032] By adopting the above-mentioned technical solution, the beneficial effects of a radiator provided by the utility model are as follows:

[0033] Through the snap-on assembly, the radiator body and the frame, as well as the frame and the air guide cover are quickly snapped together, which not only simplifies the assembly process and improves the assembly efficiency, but also does not require the aid of tooling during the assembly process, has high assembly precision, good positioning effect after assembly, and high positioning reliability.
