[0046] Figure 1 is one of the three-dimensional structural diagrams of the buckle provided in the embodiment of the present application, such as Figure 1 As shown, the buckle includes a buckle body 100, which includes a fixing portion 110, at least one slot 120 and at least one limiting portion 130. The fixing portion 110 is suitable for fixing the part to be fixed 200, the slot 120 is suitable for snap-fitting with the socket 300, and the limiting portion 130 is suitable for limiting cooperation with the socket 300 to prevent the socket 300 from slipping out of the slot 120.

[0047] According to the buckle of the embodiment of the present application, the part to be fixed is fixed by adopting the snap-fitting cooperation between the card slot 120 and the card seat 300, which effectively simplifies the fixing method of the part to be fixed, avoids the problem of thread slippage when fixing with screws, and improves the stability of the fixation of the part to be fixed; by setting the limiting part 130 and the card seat 300 to limit the cooperation, so as to avoid the card seat 300 from slipping out of the card slot 120, the stability of the fixation of the part to be fixed is further improved.

[0048] It is understandable 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 slots 120 or more.

[0049] It can be understood that the buckle body 100 includes two card slots 120, and the two card slots 120 have the same shape and are symmetrically arranged; of course, the shapes of the two card slots 120 may also be different.

[0050] It can be understood that the part to be fixed 200 is a wire harness, specifically, the wire harness is a wire harness inside the refrigeration equipment; of course, the part to be fixed 200 can also be a pipeline or other parts to be fixed.

[0051] It is understandable that if Figure 1As shown, the fixing portion 110 includes a fixing cavity 111, and the fixing cavity 111 penetrates the buckle body 100 to form ports at the first end and the second end of the buckle body 100, respectively. The fixing cavity 111 is suitable for fixing the to-be-fixed member 200. The to-be-fixed member 200 is arranged in the fixing cavity 111 to achieve the fixation of the to-be-fixed member 200. The cross-sectional shape of the fixing cavity 111 is the same as the cross-sectional shape of the to-be-fixed member 200. In this embodiment, the cross-sectional shape of the fixing cavity 111 is circular, and of course, it can also be elliptical, rectangular or other shapes, which is specifically determined according to the cross-sectional shape of the to-be-fixed member 200.

[0052] It can be understood that the outer diameter of the wire harness is a fixed value, and the inner diameter of the fixing cavity 111 is a fixed value, that is, the inner diameters of any two places of the fixing cavity 111 are equal, so that after the wire harness is inserted into the fixing cavity 111, the inner wall of any place of the fixing cavity 111 is in contact with the wire harness, which improves the stability of the wire harness after being fixed. Of course, the inner diameter of the fixing cavity 111 can also gradually increase along the direction from the first end of the buckle body 100 to the second end of the buckle body 100.

[0053] It is also understandable that Figure 1 As shown, the wire harness is passed through the fixing cavity 111, and the buckle body 100 is integrally formed with the wire harness. Specifically, the buckle body 100 is integrally formed with the insulating layer of the wire harness. Such a setting further reduces the number of components and reduces the production cost.

[0054] It can be understood 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 achieve fixation of the wire harness.

[0055] It should be noted here that the structure of the fixing cavity 111 is not limited to a through hole, but may also be a slot, that is, the cross section of the fixing cavity 111 is C-shaped.

[0056] It is understandable that the buckle body 100 may be made of plastic or rubber so that the buckle body 100 has a certain elasticity and the opening 112 may be deformed during the opening and closing process.

[0057] It is understandable that if Figure 1 As shown, the fixing portion 110 further includes an opening 112, which is disposed on the side wall of the fixing cavity 111, and is communicated with the fixing cavity 111. The opening 112 extends in a direction from the first end of the buckle body 100 to the second end of the buckle body 100, and the length of the opening 112 is the same as the length of the fixing cavity 111. The opening 112 is suitable for the wire harness to enter the fixing cavity 111, and for the wire harness to be taken out of the fixing cavity 111.

[0058] It is understandable that if Figure 1 As shown, the side wall of the opening 112 is a plane. When the side wall of the opening 112 is not squeezed, the two side walls of the opening 112 are parallel to each other, that is, the width of any part of the opening 112 is equal; when the side wall of the opening 112 is squeezed, the two side walls of the opening 112 fit together. Of course, in order to facilitate the wire harness to enter the fixed cavity 111 through the opening 112, the side wall of the opening 112 can also be set as an inclined surface. When the side wall of the opening 112 is not squeezed, the width of the opening 112 gradually decreases from away from the fixed cavity 111 to close to the fixed cavity 111. The advantage of such a setting is that when the opening 112 is in an open state, it is convenient for the wire harness to enter the fixed cavity 111 through the opening 112.

[0059] It can be understood 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. When the opening 112 is in a closed state, the positioning protrusion is embedded in the positioning hole to achieve the positioning and matching of the two side walls of the opening 112. One or more positioning protrusions can be provided, the number of positioning holes is the same as the number of positioning protrusions, and the positions of the positioning holes correspond to the positions of the positioning protrusions one by one.

[0060] Understandably, Figure 2 This is the second schematic diagram of the three-dimensional structure of the buckle provided in the embodiment of the present application, such as Figure 2 As shown, the inner wall of the fixed cavity 111 is provided with a plurality of elastic contact pieces 113. During the process of the card holder 300 and the card slot 120 being engaged, the side wall of the opening 112 is squeezed, the width of the opening 112 is reduced, the inner diameter of the fixed cavity 111 is reduced, and the elastic contact piece 113 is deformed to fit closely with the outer peripheral surface of the wire harness, thereby fixing the wire harness in the fixed cavity 111. The deformation size of the elastic contact piece 113 is related to the outer diameter of the wire harness. When the outer diameter of the wire harness is small, the deformation of the elastic contact piece 113 is small; when the outer diameter of the wire harness is large, the deformation of the elastic contact piece 113 is large. By providing the elastic contact piece 113, the fixed cavity 111 can be adapted to wire harnesses of different outer diameters, thereby increasing the versatility of the buckle.

[0061] It is understandable that the material of the elastic contact piece 113 is the same as that of the buckle body 100 , and the elastic contact piece 113 and the buckle body 100 are integrally formed to simplify the buckle manufacturing process and reduce production costs.

[0062] It can also be understood that the material of the elastic contact piece 113 is different from that of the buckle body 100, and the friction coefficient of the elastic contact piece 113 is greater than the friction coefficient of the buckle body 100. This can increase the friction force between the elastic contact piece 113 and the wiring harness during contact, preventing relative movement between the wiring harness and the buckle.

[0063] It can be understood that the elastic contact piece 113 extends circumferentially along the inner wall of the fixing cavity 111, and the elastic contact piece 113 is annular or C-shaped. With such a structure, the contact area between the elastic contact piece 113 and the wire harness can be increased, and the stability of the wire harness when fixed can be improved. A 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. By providing a plurality of elastic contact pieces 113, the contact area between the elastic contact piece 113 and the wire harness can be further increased, and the stability of the wire harness when fixed can be improved. The distance between two adjacent elastic contact pieces 113 is equal, and the distance between two adjacent elastic contact pieces 113 is specifically determined according to the length of the fixing cavity 111.

[0064] It should be noted that the structure of the elastic contact member 113 is not limited to a ring shape or a C shape, and may also be a columnar body or a hemispherical shape.

[0065] Furthermore, in order to increase the contact surface between the elastic contact piece 113 and the wiring harness after deformation, the thickness of the side of the elastic contact piece 113 away from the inner wall of the fixing cavity 111 is less than the thickness of the side of the elastic contact piece 113 close to the inner wall of the fixing cavity 111, and the cross section of the elastic contact piece 113 is triangular or trapezoidal. During the process of the card holder 300 and the card slot 120 being engaged, the inner diameter of the fixing cavity 111 is reduced, the elastic contact piece 113 is squeezed and deformed, and the contact area between the elastic contact piece 113 and the wiring harness is increased, thereby preventing the wiring harness and the buckle from moving relative to each other.

[0066] Understandably, Figure 3 is a schematic diagram of a partial cross-sectional structure of a buckle provided in an embodiment of the present application, such as Figure 3 As shown, the buckle body 100 includes two slots 120, which are respectively located on both sides of the opening 112. The slots 120 extend in the direction from the first end of the buckle body 100 to the second end of the buckle body 100. The slots 120 are parallel to the fixing cavity 111, that is, the length direction of the slots 120 is the same as the length direction of the fixing cavity 111, and the cross section of the buckle is Ω-shaped. The two slots 120 are symmetrically arranged about the opening 112, and the heights of the two slots 120 are equal. With such a structural design, the buckle can be conveniently produced in large quantities, reducing the production cost of the buckle.

[0067] It should be noted that the height of the card slot 120 refers to the height of the card slot 120. Figure 3 The width of the slot 120 refers to the size of the slot 120 in the vertical direction. Figure 3 The horizontal dimension.

[0068] It should be noted that the length direction of the slot 120 may also be at a certain angle to the length direction of the fixed cavity 111, for example, the length direction of the slot 120 is perpendicular to the length direction of the fixed cavity 111. In this case, the side wall of the slot 120 needs to be provided with a strip hole for the wiring harness to pass through.

[0069] It is understandable that if Figure 3 As shown, the card slot 120 extends from the first end of the buckle body 100 to the second end of the buckle body 100, and the length of the card slot 120 can be equal to the length of the buckle body 100, or it can be less than the length of the buckle body 100, that is, the card slot 120 can pass through the buckle body 100. In this embodiment, the length of the card slot 120 is less than the length of the buckle body 100, so that the card slot 120 forms a positioning surface at the end away from the first notch 121, and the card connecting piece 310 abuts against the positioning surface during the process of being inserted into the card slot 120, thereby realizing the positioning of the card connecting piece 310, making the operation more convenient and improving the assembly efficiency.

[0070] The first notch 121 suitable for the card holder 300 to be inserted into the card slot 120 is formed at the first end of the buckle body 100 of the card slot 120. The first notch 121 is suitable for the card engaging piece 310 to be inserted into the card slot 120 and the card engaging piece 310 to slide out of the card slot 120. Furthermore, in order to facilitate the card engaging piece 310 to be inserted into the card slot 120, an inclined surface or a curved surface may be provided at the edge of the first notch 121 to increase the width of the first notch 121, so that the height of the first notch 121 is greater than the height of the card slot 120. In the process of inserting the card engaging piece 310 into the card slot 120, the card engaging piece 310 can be easily inserted into the card slot 120, the operation is simpler, and the assembly efficiency is improved.

[0071] It is understandable that if Figure 3 As shown, the width of the slot 120 gradually decreases along the direction from the first end of the buckle body 100 to the second end of the buckle body 100, so that the thickness of the side wall of the slot 120 gradually increases along the direction from the first end of the buckle body 100 to the second end of the buckle body 100. In the process of the snap-in piece 310 being snapped into the slot 120, since the positions of the two snap-in pieces 310 are fixed and the sum of the thickness of the side walls of the two slots 120 is constantly increasing, the two snap-in pieces 310 continuously squeeze the side walls of the two slots 120, so that the width of the opening 112 gradually decreases; as the depth of the snap-in piece 310 being snapped into the slot 120 increases, the amplitude of the two snap-in pieces 310 squeezing the side walls of the two slots 120 increases, and the snap-in fit between the buckle body 100 and the slot 120 becomes tighter.

[0072] It should be noted here that when the width of the slot 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 snap-on plates 310 can be a fixed value or a variable value. Regardless of whether the distance between the two snap-on plates 310 changes, it can be achieved that the greater the depth of the snap-on plates 310 inserted into the slot 120, the tighter the snap-on body 100 and the slot 120 can be snapped together.

[0073] It should also be noted that, in the case where two slots 120 are provided, the widths of the two slots 120 are gradually reduced along the direction from the first end of the buckle body 100 to the second end of the buckle body 100. Of course, the width of only one slot 120 may be gradually reduced along the direction from the first end of the buckle body 100 to the second end of the buckle body 100, and the width of the other slot 120 remains unchanged or changes less than the width of the previous slot 120.

[0074] It is understandable that the thickness of the slot 120 gradually decreases along the direction from the first end of the buckle body 100 to the second end of the buckle body 100. In the process of the snap-in piece 310 being snapped into the slot 120, although the thickness of the snap-in piece 310 is fixed, since the thickness of the slot 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 greater the depth of the snap-in piece 310 being snapped into the slot 120, the tighter the snap-in piece 310 and the slot 120 are snapped. Relative movement between the buckle and the base 300 is avoided.

[0075] It is understandable that if Figure 3 As shown, the limiting portion 130 includes a limiting block 131, which is arranged on the bottom wall of the card slot 120, and the limiting block 131 and the bottom wall of the card slot 120 are integrally formed. Of course, the limiting block 131 and the bottom wall of the card slot 120 can also be integrally formed, for example, a groove is arranged on the bottom wall of the card slot 120, and the limiting block 131 is embedded in the groove. Of course, the limiting block 131 and the bottom wall of the card slot 120 can also be connected by bonding or screws. The side of the limiting block 131 away from the first notch 121 has a limiting surface that is limited to the card holder 300, and the limiting surface is perpendicular to the bottom wall of the card slot 120. The limiting surface is suitable for limiting the card holder 300, preventing the card connector 310 from sliding out of the card slot 120, resulting in the separation of the buckle and the card holder 300, and improving the stability of the buckle and the card holder 300 during the card connection process. In this embodiment, the limiting block 131 is located at a side of the bottom wall of the slot 120 close to the first notch 121 . Of course, the limiting block 131 can also be disposed at other positions of the bottom wall of the slot 120 .

[0076] Furthermore, the height of the limiting surface is greater than or equal to the thickness of the engaging piece 310 . The advantage of such a setting is that even if the engaging piece 310 moves, the engaging piece 310 cannot cross the limiting surface, thereby preventing the engaging piece 310 from sliding over the upper part of the limiting block 131 .

[0077] It is understandable that if Figure 3 As shown, the side of the limit block 131 facing the first notch 121 has a guide surface 132 connected to the limit surface, and the guide surface 132 is inclined downward toward the first notch 121. The guide inclined surface can guide the card piece 310, making it convenient for the card piece 310 to slide into the card slot 120, reducing the obstruction of the limit block 131 to the card piece 310, and facilitating the assembly of the buckle and the card seat 300. The guide surface 132 can be an inclined surface or a curved surface.

[0078] Combine the following Figures 1 to 4 Describe a specific embodiment of the present application, such as Figures 1 to 4 As shown, the buckle includes a buckle body 100 , and the buckle body 100 may be made of plastic or rubber. The buckle body 100 includes a fixing portion 110 , two slots 120 and two limiting portions 130 .

[0079] The fixing portion 110 is suitable for fixing the part to be fixed 200. The fixing portion 110 includes a fixing cavity 111 and an opening 112. The fixing cavity 111 is a circular through hole structure. The fixing cavity 111 penetrates the buckle body 100 to form ports at the first end and the second end of the buckle body 100, respectively. The fixing cavity 111 is suitable for fixing the part to be fixed 200. The part to be fixed 200 is arranged in the fixing cavity 111 to achieve the fixation of the part to be fixed 200. The cross-sectional shape of the fixing cavity 111 is the same as the cross-sectional shape of the part to be fixed 200. In this embodiment, the cross-sectional shape of the fixing cavity 111 is circular. The outer diameter of the wiring harness is a fixed value, and the inner diameter of the fixing cavity 111 is a fixed value, that is, the inner diameters of any two places of the fixing cavity 111 are equal. The opening 112 is connected to the fixing cavity 111, and the opening 112 extends in the direction from the first end of the buckle body 100 to the second end of the buckle body 100, and the length of the opening 112 is the same as the length of the fixing cavity 111. The sidewalls of the opening 112 are planes. When the sidewalls of the opening 112 are not squeezed, the two sidewalls of the opening 112 are parallel to each other, that is, the widths of any part of the opening 112 are equal; when the sidewalls of the opening 112 are squeezed, the two sidewalls of the opening 112 fit together.

[0080] The inner wall of the fixed cavity 111 is provided with a plurality of elastic contact members 113. The material of the elastic contact members 113 is the same as that of the buckle body 100. The elastic contact members 113 and the buckle body 100 are integrally formed to simplify the manufacturing process of the buckle and reduce the production cost. The elastic contact members 113 extend circumferentially along the inner wall of the fixed cavity 111, and the elastic contact members 113 are annular. The plurality of elastic contact members 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 the distance between two adjacent elastic contact members 113 is equal, and the thickness of two adjacent elastic contact members 113 is equal. The thickness of the side of the elastic contact member 113 away from the inner wall of the fixed cavity 111 is less than the thickness of the side of the elastic contact member 113 close to the inner wall of the fixed cavity 111, and the cross section of the elastic contact member 113 is triangular.

[0081] The card slot 120 is suitable for engaging with the card holder 300. The buckle body 100 is provided with two card slots 120, which are respectively located on both sides of the opening 112. The card slot 120 extends from the first end of the buckle body 100 to the second end of the buckle body 100.

The two card slots 120 are symmetrically arranged about the opening 112, and the thickness of the two card slots 120 is equal.

[0082] The length of the card slot 120 is smaller than that of the buckle body 100 , and a positioning surface is formed at the end of the card slot 120 away from the first notch 121 . When the card connecting piece 310 is inserted into the card slot 120 , it abuts against the positioning surface, thereby positioning the card connecting piece 310 , making the operation more convenient and improving the assembly efficiency.

[0083] The card slot 120 forms a first notch 121 at the first end of the buckle body 100, which is suitable for the card holder 300 to be inserted into the card slot 120. The first notch 121 is suitable for the card connecting piece 310 to be inserted into the card slot 120 and the card connecting piece 310 to slide out of the card slot 120. The width of the card slot 120 gradually decreases along the direction from the first end of the buckle body 100 to the second end of the buckle body 100, so that the side wall thickness of the card slot 120 gradually increases along the direction from the first end of the buckle body 100 to the second end of the buckle body 100.

[0084] The limiting portion 130 is suitable for limiting the engagement with the card holder 300 to prevent the card holder 300 from sliding out of the card slot 120. The limiting portion 130 includes a limiting block 131, which is arranged on the bottom wall of the card slot 120, and the limiting block 131 is integrally formed with the bottom wall of the card slot 120. The limiting block 131 has a limiting surface that is limited to the card holder 300 on the side away from the first slot 121, and the limiting surface is perpendicular to the bottom wall of the card slot 120, and the limiting surface is suitable for limiting the card holder 300. The height of the limiting surface is greater than or equal to the thickness of the card connector 310. The limiting block 131 has a guide surface 132 connected to the limiting surface on the side facing the first slot 121, and the guide surface 132 is inclined downward toward the first slot 121. The guiding inclined surface can guide the card connector 310, and the guide surface 132 can be an inclined surface.

[0085] According to the buckle of the embodiment of the present application, the wiring harness is fixed by adopting a snap-fitting manner of the card slot 120 and the card holder 300, which effectively simplifies the fixing method of the wire harness, avoids the problem of thread slippage when fixing with screws, and improves the stability of the fixing of the wire harness; by setting a limiting portion 130 and the card holder 300 to limit the card holder 300 to prevent the card holder 300 from slipping out of the card slot 120, the stability of the fixing of the wire harness is further improved.

[0086] Figure 4 : is a schematic diagram of the assembly relationship between the fixing member, the buckle and the holder provided in the embodiment of the present application, Figure 5 is a schematic diagram of the structure of the fixed member, the buckle and the holder after separation provided in the embodiment of the present application, such as Figure 4 and Figure 5 As shown, the second aspect of the present application further provides a snap assembly, which includes a socket 300 and the snap described in any one of the above embodiments, and the socket 300 includes a snap-in piece 310, which is suitable for snapping into the slot 120 to achieve snap-fitting between the socket 300 and the slot 120.

[0087] It can also be understood that two clamping pieces 310 can be provided, and the two clamping pieces 310 can be symmetrically or asymmetrically arranged, as long as the width of the clamping groove 311 between the two clamping pieces 310 can be gradually increased along the direction from the first end of the buckle body 100 to the second end of the buckle body 100. The two clamping pieces 310 can be provided on the same fixing plate 400, or the two clamping pieces 310 can be connected by a connecting piece, and then connected to the fixing plate 400 by the connecting piece.

[0088] Of course, one clamping piece 310 may also be provided. In this case, the clamping seat 300 further includes a limiting protrusion, and the clamping slot 120 is provided with one limiting protrusion (not shown) and the clamping piece 310 are arranged at intervals. The clamping piece 310 and the clamping slot 120 are located on the same side of the buckle body 100, and the limiting protrusion is located on the other side of the buckle body 100. When the clamping piece 310 is inserted into the clamping slot 120, the other side of the buckle body 100 abuts against the limiting protrusion, and the limiting protrusion plays a limiting role on the buckle body 100.

[0089] It can also be understood that the card seat 300 includes two card plates 310, and the two card plates 310 are arranged at intervals to form a card slot 311 between the two card plates 310; the card slot 311 is engaged with the side wall of the card slot 120, and the width of the card slot 311 gradually increases along the direction from the first end of the buckle body 100 to the second end of the buckle body 100. In the process of the card plate 310 being engaged with the card slot 120, since the width of the card slot 311 gradually decreases, the greater the depth of the card plate 310 being engaged with the card slot 120, the more firmly the side wall of the opening 112 is engaged with the card slot 311. Of course, the width of the card slot 311 can also be a fixed value, that is, the card slot 311 is a rectangular slot, and the arc slot can also cooperate with the above-mentioned card slot 120, so that the greater the depth of the card plate 310 being engaged with the card slot 120, the more firmly the side wall of the opening 112 is engaged with the card slot 311.

[0090] It can also be understood that the thickness of the bottom wall of the card slot 120 gradually increases along the direction from the first end of the buckle body 100 to the second end of the buckle body 100. Since the distance between the clamping piece 310 and the fixing plate 400 is fixed, during the process of the clamping piece 310 being clamped into the card slot 120, the bottom wall of the card slot 120 is clamped between the clamping piece 310 and the fixing plate 400. Since the thickness of the bottom wall of the card slot 120 gradually increases along the direction from the first end of the buckle body 100 to the second end of the buckle body 100, the deeper the bottom wall of the card slot 120 is clamped between the clamping piece 310 and the fixing plate 400, the more tightly the buckle body 100 and the base 300 are clamped together.

[0091] The third aspect of the present application further provides a refrigeration device, which includes a refrigeration device body, a fixing plate 400, and the buckle described in any one of the above embodiments or the buckle assembly described in any one of the above embodiments; the fixing plate 400 is arranged inside the refrigeration device body, and the holder 300 is arranged on the fixing plate 400. By adopting the above buckle, the assembly efficiency of the refrigeration device is improved, the user experience is enhanced, and the product competitiveness is improved.

[0092] It should be noted that in this embodiment, the two clamping pieces 310 are symmetrically arranged, and the clamping pieces 310 are integrally formed or welded with the fixing plate 400. The refrigeration device may be a refrigerator, a freezer, a medicine box, a display cabinet or other refrigeration equipment.
