According to the buckle provided by the embodiment of the application, the clamping groove 120 is used for clamping and matching with the clamping seat 300 to fix the to-be-fixed piece, so that the fixing mode of the to-be-fixed piece is effectively simplified, the problem of sliding wire caused by screw fixing is avoided, the fixing stability of the to-be-fixed piece is improved, and the limiting part 130 is used for limiting and matching with the clamping seat 300 to prevent the clamping seat 300 from sliding out of the clamping groove 120, and the fixing stability of the to-be-fixed piece is further improved.

It is understood that the buckle body 100 includes a slot 120, and the width of the slot 120 gradually decreases from the first end of the buckle body 100 to the second end of the buckle body 100. Of course, the buckle body 100 may also include two card slots 120 or a greater number of card slots 120.

It can be understood that the buckle body 100 includes two slots 120, and the two slots 120 have the same shape and are symmetrically arranged, and of course, the two slots 120 may have different shapes.

It will be appreciated that the to-be-fixed member 200 is a wire harness, specifically, the wire harness is a wire harness inside the refrigeration equipment, and of course, the to-be-fixed member 200 may be a pipeline or other to-be-fixed members.

It will be appreciated that, as shown in fig. 1, the fixing portion 110 includes a fixing cavity 111, and the fixing cavity 111 penetrates through the buckle body 100 to form ports at a first end and a second end of the buckle body 100, and the fixing cavity 111 is adapted to fix the to-be-fixed piece 200. The to-be-fixed piece 200 is arranged in the fixing cavity 111 in a penetrating way so as to fix the to-be-fixed piece 200. The cross-sectional shape of the fixing cavity 111 is the same as that of the to-be-fixed member 200, and in this embodiment, the cross-sectional shape of the fixing cavity 111 is circular, but may be elliptical, rectangular or other shapes, which is specifically determined according to the cross-sectional shape of the to-be-fixed member 200.

It can be understood that the external diameter of the wire harness is a fixed value, and the internal diameter of the fixing cavity 111 is a fixed value, that is, the internal diameters of any two positions of the fixing cavity 111 are equal, so that after the wire harness is clamped into the fixing cavity 111, the internal wall of any position of the fixing cavity 111 is attached to the wire harness, and the stability of the wire harness after fixing is improved. Of course, the inner diameter of the fixing cavity 111 may also gradually increase in a direction from the first end of the buckle body 100 to the second end of the buckle body 100.

It can be further understood that, as shown in fig. 1, the wire harness is inserted into the fixing cavity 111, the buckle body 100 and the wire harness are integrally formed, specifically, the buckle body 100 and the insulation layer of the wire harness are integrally formed, and by adopting such a setting mode, the number of components is further reduced, and the production cost is reduced.

It will be appreciated that the inner diameter of the fixing cavity 111 is smaller than the outer diameter of the wire harness, so that when the opening 112 is in a closed state, the wire harness can be tightly clamped in the fixing cavity 111 to fix the wire harness.

The structure of the fixing cavity 111 is not limited to the structure of the through hole, but may be a structure of a slot, that is, the cross section of the fixing cavity 111 is C-shaped.

It is understood that the material of the buckle body 100 may be plastic or rubber, so that the buckle body 100 has a certain elasticity, and the opening 112 may deform during the opening and closing process of the buckle body 100.

It will be appreciated that, as shown in fig. 1, the fixing portion 110 further includes an opening 112, the opening 112 is disposed on a side wall of the fixing cavity 111, the opening 112 is in communication with the fixing cavity 111, the opening 112 extends along a direction from the first end of the buckle body 100 to the second end of the buckle body 100, and a length of the opening 112 is the same as a length of the fixing cavity 111. The opening 112 is adapted for the wire harness to enter the fixing chamber 111 and for the wire harness to be taken out of the fixing chamber 111.

It will be appreciated that, as shown in fig. 1, the side walls of the opening 112 are planar, when the side walls of the opening 112 are not pressed, the two side walls of the opening 112 are parallel to each other, i.e. the width of any place of the opening 112 is equal, and when the side walls of the opening 112 are pressed, the two side walls of the opening 112 are attached. Of course, in order to facilitate the wire harness entering the fixing cavity 111 through the opening 112, the side wall of the opening 112 may be provided with an inclined surface, and when the side wall of the opening 112 is not pressed, the width of the opening 112 gradually decreases from a direction away from the fixing cavity 111 to a direction close to the fixing cavity 111.

It will be appreciated that one of the two side walls of the opening 112 is provided with a positioning protrusion, and the other of the two side walls of the opening 112 is provided with a positioning hole, and when the opening 112 is in the closed state, the positioning protrusion is embedded in the positioning hole to realize positioning fit of the two side walls of the opening 112. The positioning protrusions can be arranged in one or a plurality of positions, the number of the positioning holes is the same as that of the positioning protrusions, and the positions of the positioning holes correspond to the positions of the positioning protrusions one by one.

It can be understood that fig. 2 is a schematic diagram of a second perspective view of a buckle provided in an embodiment of the present application, as shown in fig. 2, a plurality of elastic contacts 113 are disposed on an inner wall of the fixing cavity 111, and during a process of clamping the clamping seat 300 and the clamping slot 120, a side wall of the opening 112 is extruded, a width of the opening 112 is reduced, an inner diameter of the fixing cavity 111 is reduced, and the elastic contacts 113 are deformed to be closely attached to an outer peripheral surface of the wire harness, so that the wire harness is fixed in the fixing cavity 111. The size of deformation of the elastic contact 113 is related to the outer diameter of the wire harness, when the outer diameter of the wire harness is smaller, the deformation of the elastic contact 113 is smaller, when the outer diameter of the wire harness is larger, the elastic contact 113 is larger, and the fixing cavity 111 can be matched with the wire harnesses with different outer diameters through the arrangement of the elastic contact 113, so that the universality of the buckle is improved.

It can be understood that the material of the elastic contact 113 is the same as that of the buckle body 100, and the elastic contact 113 and the buckle body 100 are integrally formed, so as to simplify the manufacturing process of the buckle and reduce the production cost.

It can be further understood that the material of the elastic contact 113 is different from that of the buckle body 100, and the friction coefficient of the elastic contact 113 is greater than that of the buckle body 100, so that the friction force between the elastic contact 113 and the wire harness in the contact process can be increased, and the wire harness and the buckle are prevented from moving relatively.

It can be appreciated that the elastic contact 113 extends along the circumferential direction of the inner wall of the fixing cavity 111, and the elastic contact 113 is annular or C-shaped. The plurality of elastic contact pieces 113 are arranged at intervals along the direction from the first end of the buckle body 100 to the second end of the buckle body 100, and by arranging the plurality of elastic contact pieces 113, the contact area between the elastic contact pieces 113 and the wire harness can be further increased, and the stability of the wire harness during fixing is improved. The distances between the adjacent two elastic contacts 113 are equal, and the distance between the adjacent two elastic contacts 113 is determined specifically according to the length of the fixing chamber 111.

The configuration of the elastic contact 113 is not limited to a ring shape or a C-shape, and may be a columnar body, a hemispherical body, or the like.

Further, in order to increase the contact surface with the wire harness after the elastic contact 113 is deformed, the thickness of the elastic contact 113 on the side far from the inner wall of the fixing cavity 111 is smaller than the thickness of the elastic contact 113 on the side near to the inner wall of the fixing cavity 111, and the cross section of the elastic contact 113 is triangular or trapezoidal. In the process of clamping the clamping seat 300 and the clamping groove 120, the inner diameter of the fixing cavity 111 is reduced, the elastic contact piece 113 is extruded to deform, the contact area between the elastic contact piece 113 and the wire harness is increased, and the wire harness and the buckle are prevented from moving relatively.

It can be understood that fig. 3 is a schematic diagram of a partial cross-sectional structure of a buckle according to an embodiment of the present application, as shown in fig. 3, the buckle body 100 includes two clamping grooves 120, the two clamping grooves 120 are respectively located at two sides of the opening 112, the clamping grooves 120 extend along a direction from a first end of the buckle body 100 to a second end of the buckle body 100, the clamping grooves 120 are parallel to the fixing cavity 111, i.e. a length direction of the clamping grooves 120 is the same as a length direction of the fixing cavity 111, and a cross section of the buckle is in an Ω shape. The two clamping grooves 120 are symmetrically arranged about the opening 112, the heights of the two clamping grooves 120 are equal, and the adoption of the structural design can facilitate mass production of the buckle and reduce the production cost of the buckle.

The height of the card slot 120 refers to the dimension of the card slot 120 in the vertical direction in fig. 3, and the width of the card slot 120 refers to the dimension of the card slot 120 in the horizontal direction in fig. 3.

It should be noted that, the length direction of the clamping groove 120 may also form a certain angle with the length direction of the fixing cavity 111, for example, the length direction of the clamping groove 120 is perpendicular to the length direction of the fixing cavity 111. In this case, the side wall of the card slot 120 needs to be provided with a bar-shaped hole for the wire harness to pass through.

It will be appreciated that, as shown in fig. 3, the slot 120 extends from the first end of the buckle body 100 to the second end of the buckle body 100, the length of the slot 120 may be equal to the length of the buckle body 100, and the length of the slot 120 may be smaller than the length of the buckle body 100, i.e. the slot 120 may extend through the buckle body 100. The length of the clamping groove 120 in this embodiment is smaller than that of the buckle body 100, so that the clamping groove 120 forms a positioning surface at one end far away from the first notch 121, and the clamping piece 310 is abutted to the positioning surface in the process of being clamped into the clamping groove 120, so that the positioning of the clamping piece 310 is realized, the operation is more convenient, and the assembly efficiency is improved.

The clamping groove 120 forms a first notch 121 at the first end of the clamping body 100, which is suitable for the clamping seat 300 to be clamped into the clamping groove 120, and the first notch 121 is suitable for the clamping piece 310 to be clamped into the clamping groove 120 and the clamping piece 310 to slide out of the clamping groove 120. Further, in order to facilitate the engagement of the engaging piece 310 into the engaging groove 120, an inclined surface or a curved surface may be provided at the edge of the first slot 121 to increase the width of the first slot 121, such that the height of the first slot 121 is greater than the height of the engaging groove 120. In the process of clamping the clamping piece 310 into the clamping groove 120, the clamping piece 310 can be easily clamped into the clamping groove 120, the operation is simpler and more convenient, and the assembly efficiency is improved.

It will be appreciated that, as shown in fig. 3, the width of the slot 120 gradually decreases from the first end of the buckle body 100 to the second end of the buckle body 100, so that the thickness of the sidewall of the slot 120 gradually increases from the first end of the buckle body 100 to the second end of the buckle body 100. In the process of clamping the clamping pieces 310 into the clamping grooves 120, as the positions of the two clamping pieces 310 are fixed and the sum of the thicknesses of the side walls of the two clamping grooves 120 is continuously increased, the two clamping pieces 310 continuously press the side walls of the two clamping grooves 120, so that the width of the opening 112 is gradually reduced, and as the depth of the clamping pieces 310 clamped into the clamping grooves 120 is larger, the width of the clamping pieces 310 pressing the side walls of the two clamping grooves 120 is larger, and the clamping body 100 is fastened in clamping fit with the clamping grooves 120.

It should be noted that, in the case that the width of the clamping groove 120 gradually decreases along the direction from the first end of the buckle body 100 to the second end of the buckle body 100, the distance between the two clamping pieces 310 may be a fixed value or may be variable, and the greater the depth of the clamping piece 310 clamped into the clamping groove 120, the more fastening the buckle body 100 is clamped and matched with the clamping groove 120 can be achieved no matter whether the distance between the two clamping pieces 310 is variable.

It should be further noted that, in the case where two card slots 120 are provided, the widths of the two card slots 120 are gradually reduced in a direction from the first end of the buckle body 100 to the second end of the buckle body 100. Of course, only one of the clamping grooves 120 may gradually decrease in width from the first end of the buckle body 100 to the second end of the buckle body 100, and the width of the other clamping groove 120 is unchanged or smaller than the width of the previous clamping groove 120.

It is understood that the thickness of the clamping groove 120 gradually decreases from the first end of the buckle body 100 to the second end of the buckle body 100. During the process of the locking tab 310 being locked into the locking groove 120, although the thickness of the locking tab 310 is fixed, the greater the depth of the locking tab 310 locked into the locking groove 120, the more tightly the locking tab 310 is locked with the locking groove 120, because the thickness of the locking groove 120 gradually decreases in a direction from the first end of the buckle body 100 to the second end of the buckle body 100. The relative movement between the buckle and the clamping seat 300 is avoided.

It should be understood that, as shown in fig. 3, the limiting portion 130 includes a limiting block 131, the limiting block 131 is disposed on the bottom wall of the card slot 120, the limiting block 131 and the bottom wall of the card slot 120 are integrally formed, and of course, the limiting block 131 and the bottom wall of the card slot 120 may be integrally formed, for example, a groove is disposed on the bottom wall of the card slot 120, and the limiting block 131 is embedded in the groove, and of course, the limiting block 131 and the bottom wall of the card slot 120 may be adhesively connected or screwed. One side of the limiting block 131, which is away from the first notch 121, is provided with a limiting surface in limiting fit with the clamping seat 300, the limiting surface is perpendicular to the bottom wall of the clamping groove 120, and the limiting surface is suitable for limiting the clamping seat 300 and preventing the clamping piece 310 from sliding out of the clamping groove 120, so that the clamping buckle is separated from the clamping seat 300, and the stability of the clamping buckle and the clamping seat 300 in the clamping fit process is improved. In this embodiment, the stopper 131 is located at a side of the bottom wall of the card slot 120 near the first notch 121, and of course, the stopper 131 may be disposed at other positions of the bottom wall of the card slot 120.

Further, the height of the limiting surface is greater than or equal to the thickness of the clamping piece 310, so that even if the clamping piece 310 is in a rectifying motion, the clamping piece 310 cannot pass over the limiting surface, and the clamping piece 310 is prevented from sliding over the upper portion of the limiting block 131.

It can be appreciated that, as shown in fig. 3, one side of the limiting block 131 facing the first notch 121 has a guiding surface 132 connected with the limiting surface, the guiding surface 132 is inclined downward toward the first notch 121, and the guiding inclined surface can guide the clamping piece 310, so that the clamping piece 310 can slide into the clamping groove 120 conveniently, the blocking of the limiting block 131 to the clamping piece 310 is reduced, and the assembly of the buckle and the clamping seat 300 is facilitated. The guide surface 132 may be an inclined surface or a curved surface.

The to-be-fixed piece 200 is arranged in the fixing cavity 111 in a penetrating way so as to fix the to-be-fixed piece 200. The cross-sectional shape of the fixing chamber 111 is the same as that of the member to be fixed 200, and the cross-sectional shape of the fixing chamber 111 in this embodiment is circular.
