Description

Technical Field

[0001] The utility model relates to the technical field of quick-disassembly structures, in particular to a quick-disassembly structure and a combination cabinet. Background Art

[0002] Generally, there is a combination cabinet composed of multiple cabinets. Most of the cabinets are fixed on the appropriate installation panels of the cabinets with bolts, screws and other locking parts. This means that when a cabinet needs to be replaced, it is necessary to use disassembly tools to remove these fixed bolts and screws before the cabinet can be replaced. At the same time, these locking parts generally pass through the inner side of the cabinet's storage space or are located on the side of the cabinet against the wall. Due to the installation position, it is inconvenient for the operator to disassemble the locking parts, which makes it time-consuming and labor-intensive to remove the bolts and screws, and the replacement of the cabinet is very troublesome.

[0007] The quick-release structure has an assembled state, in which the card connector is limited in the inner cavity by the first limiting section.

[0008] In one embodiment of the present invention, the first mounting seat includes a first limiting panel and a first mounting panel, the first limiting panel and the first mounting panel enclose a avoidance space, the limiting panel section is provided with a limiting screw hole connected to the avoidance space, a part of the structure of the clamping rod passes through the limiting screw hole and the clamping joint is exposed on the first limiting panel.

[0009] In one embodiment of the present invention, the first quick-release assembly also includes a guide plate, which is arranged in the avoidance space, and the guide plate is provided with a guide screw hole connected to the limiting screw hole, and the guide screw hole is coaxially arranged with the limiting screw hole; the guide plate is provided with a nut on the side facing away from the first limiting panel, and the nut is coaxially arranged with the guide screw hole.

[0010] In one embodiment of the present utility model, the clamping rod section includes a first clamping section and a second clamping section, the cross-sectional area of ​​the first clamping section is smaller than the cross-sectional area of ​​the second clamping section, and the cross-sectional area of ​​the guide screw hole is smaller than the cross-sectional area of ​​the limiting screw hole; the size of the first clamping section matches the size of the guide screw hole, and the size of the second clamping section matches the size of the limiting screw hole.

[0011] In one embodiment of the present invention, the second mounting seat includes a second limiting panel, a second mounting panel, and a limiting plate, wherein the second limiting panel and the second mounting panel together form the inner cavity capable of accommodating the limiting plate, the second limiting panel and the limiting plate are provided with the limiting groove, and the limiting plate and the second mounting panel together form the limiting channel;

[0012] In the assembled state, the card connector is limited in the limiting channel, and the limiting plate applies a force on the card connector toward the second installation panel.

[0013] In one embodiment of the present invention, an elastic member and a guide rod are provided on the side of the second limiting panel facing the limiting plate, the guide rod passes through the limiting plate, and the two ends of the elastic member are respectively connected to the second limiting panel and the limiting plate, so that the limiting plate can move along the axial direction of the guide rod within the installation space; the minimum distance between the limiting plate and the second installation panel is less than the height of the clamping joint, so that the elastic member applies a force on the limiting plate toward the second installation panel.

[0014] In one embodiment of the present invention, the side wall of the second limiting panel is provided with a guide window connected to the installation space, part of the structure of the limiting plate passes through the guide window to be exposed to the installation space, and the limiting plate abuts against the inner wall of the guide window.

[0018] In the technical solution of the present invention, the quick-release structure can quickly combine two cabinets equipped with the quick-release structure, and is easy to disassemble. Specifically, when it is necessary to quickly assemble two cabinets, the card joint of the card joint column can pass through the second limiting section of the limiting groove and enter the inner cavity of the second mounting portion, and then any cabinet is moved to make the card joint section pass through the second limiting section and enter the first limiting section. Because the cross-sectional area of ​​the card joint is larger than the cross-sectional area of ​​the card joint section, the card joint is blocked by the second mounting seat after the cabinet is moved, and the quick-release structure enters the assembly state; if the assembly state needs to be released, it is only necessary to move the cabinet in the opposite direction. At this time, the card joint reaches the second limiting section of the limiting groove. At this time, the card joint loses the obstruction of the second mounting seat and can be easily released from the assembly state. This means that when it is necessary to replace the cabinet of the combined cabinet, it is no longer necessary to use disassembly tools. The fixed connection relationship between any two cabinets can be released by directly pushing the cabinet, which saves time and effort, is simple to operate, and improves the efficiency of cabinet replacement.

[0032] To achieve the above purpose, the quick release structure includes a first quick release component and a second quick release component, such as Figures 1 to 5As shown, the first quick-release assembly includes a first mounting seat for connecting to a cabinet and a clamping column 10 provided on the outer wall of the first mounting seat. The clamping column 10 includes a clamping rod section 101 and a clamping joint 102 provided at one end of the clamping rod section 101. The cross-sectional area of ​​the clamping joint 102 is larger than the cross-sectional area of ​​the clamping rod section 101. The first quick-release assembly includes a second mounting seat for connecting to another cabinet. The second mounting seat is provided with a limiting groove 20B communicating with the inner cavity of the second mounting seat. The limiting groove 20B includes a first limiting section and a second limiting section. The shape of the first limiting section is adapted to the clamping rod section 101, and the shape of the second limiting section is adapted to the clamping joint 102.

[0033] The quick-release structure has an assembled state. In the assembled state, the card connector 102 is limited in the inner cavity by the first limiting section.

[0034] When the second fixing portion 20B is in the locked position, the locking member 102 is released and the locking member 103 is locked.

[0035] The first quick-release assembly includes a first mounting base for connecting to a cabinet and a clamping column 10 provided on the outer wall of the first mounting base. The first mounting base is installed on the cabinet by means of a locking member such as a screw, bolt, or latch. The locking member can be selected according to different cabinets and is not limited here. A through-hole structure is provided on one side of the first mounting base for the clamping column 10 to pass through. The clamping column 10 is screwed onto the first mounting base. The clamping column 10 includes a clamping rod section 101 and a clamping joint 102 provided at one end of the clamping rod section 101. Part of the structure of the clamping rod section 101 and the clamping joint 102 are exposed to the first mounting base. The cross-sectional shape of the clamping rod section 101 and the clamping joint 102 can be square, circular, etc., and is not limited here. Preferably, it is circular. In this case, the opening shape of the through-hole of the first mounting base is also circular to match the cross-section of the clamping rod section 101. Furthermore, the cross-sectional area of ​​the clamping joint 102 is larger than the cross-sectional area of ​​the clamping rod section 101.

[0036] The first quick-release assembly includes a second mounting base for connecting to another cabinet. The second mounting base is secured to the cabinet using a locking member such as a screw, bolt, or latch, matching the securing method of the first mounting base. A retaining groove 20B is provided on one side of the second mounting base, communicating with the inner cavity of the second mounting base. It will be understood that the second mounting base is positioned opposite the first mounting base so that the connector 102 can pass through the retaining groove 20B and enter the inner cavity of the second mounting base. Specifically, the limiting groove 20B includes a first limiting section and a second limiting section, the opening shape of one end of the first limiting section is circular, the opening shape between the two ends is square, and the opening shape of the second limiting section is circular, wherein the first limiting section and the second limiting section are connected using a rounded transition, the opening of the second limiting section is adapted to the shape of the card joint 102 and the cross-sectional area is larger than the cross-sectional area of ​​the card joint 102, to ensure that the card joint 102 can smoothly pass through the second limiting section and enter the inner cavity of the second mounting seat, and then move the cabinet body so that the card rod section 101 reaches the end of the first limiting section away from the second limiting section. At this time, the inner wall of the circular end can contact more card rod sections 101 with the same circular cross-sectional shape. When the card joint 102 passes through the second limiting section and enters the inner cavity of the second mounting seat, the cabinet is moved again to limit the card rod section 101 to the first limiting section, and the assembly state is entered, and the assembly of the two cabinets is completed. Of course, in the case of multiple cabinets, multiple quick-release structures can be used, and the first quick-release component and the second quick-release component of any quick-release structure can be arranged relative to each other, which is not limited here.

[0037] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the first mounting seat includes a first limiting panel 11 and a first mounting panel 14. The first limiting panel 11 and the first mounting panel 14 enclose a avoidance space. The limiting panel section 111 is provided with a limiting screw hole 111A connected to the avoidance space. Part of the structure of the clamping rod is passed through the limiting screw hole 111A and the clamping joint 102 is exposed on the first limiting panel 11.

[0038] In this embodiment, the first quick-release assembly also includes a first limiting panel 11 and a first mounting panel 14. The first limiting panel 11 includes a limiting panel section 111 and a bent section 112 provided at both ends of the limiting panel section 111. The bent sections 112 at both ends and the first mounting panel 14 are reserved with multiple mounting holes, which can be installed on the cabinet by means of locking parts such as screws, bolts or latches. The first limiting panel 11 and the first mounting panel 14 are combined to form a avoidance space. The limiting panel section 111 is provided with a limiting screw hole 111A connected to the avoidance space. The opening shape of the limiting screw hole 111A is circular, so that the clamping rod section 101 can pass through the limiting screw hole 111A and enter the avoidance space. The first limiting panel 11 and the first mounting panel 14 can preliminarily fix the clamping column 10 to prevent it from loosening.

[0039] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the first quick-release assembly also includes a guide plate 12, which is arranged in the avoidance space. The guide plate 12 is provided with a guide screw hole 12A connected to the limiting screw hole 111A, and the guide screw hole 12A is coaxially arranged with the limiting screw hole 111A; the guide plate 12 is provided with a nut 13 on the side facing away from the first limiting panel 11, and the nut 13 is coaxially arranged with the guide screw hole 12A.

[0040] In this embodiment, the first quick-release assembly further includes a guide plate 12, which is disposed in the avoidance space and is parallel to the limiting panel segment 111. The guide plate 12 is provided with a guide screw hole 12A communicating with the limiting screw hole 111A. The opening shape of the guide screw hole 12A is set to be circular. At the same time, the guide screw hole 12A and the limiting screw hole 111A are coaxially arranged to ensure that the connecting rod segment 101 can pass through the guide screw hole 12A and the limiting screw hole 111A in sequence. A nut 13 is provided on the side of the guide plate 12 facing away from the first limiting panel 11. The nut 13 is welded and fixed to the guide plate 12. The nut 13 and the guide screw hole 12A are coaxially arranged to ensure that the connecting rod segment 101 can enter the nut 13 and be completely fixed by the nut 13. It can be understood that the connecting rod segment 101 is screwed into the avoidance space through the limiting screw hole 111A until it is screwed into the nut 13 in a straight line, which effectively prevents the connecting rod segment 101 from having an angle deviation and a problem of being screwed in and stuck.

[0041] In one embodiment of the present invention, Figure 4 As shown, the clamping rod segment 101 includes a first clamping segment 1011 and a second clamping segment 1012, the cross-sectional area of ​​the first clamping segment 1011 is smaller than the cross-sectional area of ​​the second clamping segment 1012, and the cross-sectional area of ​​the guide screw hole 12A is smaller than the cross-sectional area of ​​the limiting screw hole 111A; the size of the first clamping segment 1011 matches the size of the guide screw hole 12A, and the size of the second clamping segment 1012 matches the size of the limiting screw hole 111A.

[0042] In this embodiment, the clamping rod segment 101 is configured as a cylindrical straight rod as a whole. The clamping rod segment 101 includes a first clamping segment 1011 and a second clamping segment 1012. The cross-sectional area of ​​the first clamping segment 1011 is smaller than the cross-sectional area of ​​the second clamping segment 1012. The cross-sectional area of ​​the guide screw hole 12A is smaller than the cross-sectional area of ​​the limiting screw hole 111A. The opening shapes of the guide screw hole 12A and the limiting screw hole 111A are both circular. The size of the first clamping segment 1011 matches the size of the guide screw hole 12A. The second clamping segment 1012 is smaller than the cross-sectional area of ​​the second clamping segment 1012. The size of 012 matches the size of the limiting screw hole 111A to ensure that the small-diameter first clamping section 1011 can easily enter the large-diameter limiting screw hole 111A. As the first clamping section 1011 is screwed in, the second clamping section 1012 passes through the limiting screw hole 111A. When the first clamping section 1011 continues to be screwed in through the guide screw hole 12A and enters the nut 13, the rod diameter of the second clamping section 1012 is larger than the aperture of the guide screw hole 12A. At this time, the second clamping section 1012 abuts against the guide plate 12, and the clamping column 10 is completely fixed.

[0043] In one embodiment of the present invention, Figure 3 As shown, the second mounting base includes a second limiting panel 20, a second mounting panel 21 and a limiting plate 22. The second limiting panel 20 and the second mounting panel 21 enclose an inner cavity that can accommodate the limiting plate 22. The second limiting panel 20 and the limiting plate 22 are provided with limiting grooves 20B. The limiting plate 22 and the second mounting panel 21 enclose a limiting channel 20A.

[0044] In the assembled state, the card connector 102 is limited in the limiting channel 20A, and the limiting plate 22 applies a force on the card connector 102 toward the second installation panel 21 .

[0045] In this embodiment, the second mounting seat includes a second limiting panel 20, a second mounting panel 21 and a limiting plate 22. The second limiting panel 20 has the same shape as the first limiting panel, including a limiting plate section and a bent section 112 at both ends of the limiting plate section. The limiting plate section and the bent section 112 are bent and connected. The bent sections 112 at both ends and the second mounting panel 21 are provided with a plurality of reserved mounting holes, which can be installed on another cabinet by means of locking members such as screws, bolts or latches. The second limiting panel 20 and the second mounting panel 21 are enclosed to form an inner cavity. The second limiting panel 20 has a limiting groove 20B connected to the inner cavity so that the clamping rod section 101 and the clamping joint 102 can enter the cavity; a curved limiting plate 22 is provided in the inner cavity, and the limiting plate 22 The limiting groove 20B is arranged to be aligned with the limiting groove 20B of the second limiting panel 20, and the limiting plate 22 and the second installation panel 21 are enclosed to form a limiting channel 20A. The card joint 102 can move in the limiting channel 20A. When entering the assembly state, the limiting plate 22 can apply a force toward the second installation panel 21 to the card joint 102 through some elastic parts such as springs 202, elastic arms and other structures, so that the two sides of the card joint 102 respectively abut the second installation panel 21 and the limiting plate 22. Under the action of the elastic parts, the card joint 102 is pressed tightly and thus clamped in the limiting channel 20A, preventing the card joint 102 from moving after the quick-release structure enters the assembly state, thereby preventing the two connected cabinets from moving relative to each other.

[0046] In one embodiment of the present invention, Figure 3 As shown, an elastic member and a guide rod 201 are provided on the side of the second limiting panel 20 facing the limiting plate 22, and the guide rod 201 passes through the limiting plate 22. The two ends of the elastic member are respectively connected to the second limiting panel 20 and the limiting plate 22, so that the limiting plate 22 can move along the axial direction of the guide rod 201 in the inner cavity; the minimum distance between the limiting plate 22 and the second mounting panel 21 is less than the height of the card joint 102, so that the elastic member applies a force on the limiting plate 22 toward the second mounting panel 21.

[0047] In this embodiment, an elastic member and a guide rod 201 are provided on the side of the second limiting panel 20 facing the limiting plate 22. Two reserved holes are provided at one end of the limiting plate 22 for the guide rod 201 to pass through. At the same time, the distal end of the guide rod 201 has a semicircular clamping head with a cross-section larger than the rod diameter of the guide rod 201. A pressure is applied to the limiting plate 22 so that the limiting plate 22 can be assembled with the guide rod 201 with the help of the reserved holes, so that the guide rod 201 passes through the limiting plate 22; the elastic member is provided between the limiting plate 22 and the second limiting panel 20, and at the same time, the two ends of the elastic member can abut the second limiting panel 20 and the limiting plate 22. By virtue of the elastic force of the elastic member, the limiting plate 22 can be moved along the axial direction of the guide rod 201, so that it can abut the clamping joint 102. Before the card connector 102 enters the limiting channel 20A, the minimum distance between the limiting plate 22 and the second mounting panel 21 is less than the height of the card connector 102, so that after the card connector 102 enters the limiting channel 20A, the card connector 102 can in turn squeeze the limiting plate 22. Under the action of this squeezing force, the elastic member is compressed. At the same time, the elastic member in turn applies a force to the limiting plate 22 on the second mounting panel 21, thereby ensuring that the card connector 102 is pressed tightly and that the elastic member can apply a greater force to the limiting plate 22. It is understandable that the smaller the minimum distance between the limiting plate 22 and the second mounting panel 21, the greater the force exerted by the elastic member on the limiting plate 22 after the card connector 102 enters the limiting channel 20A, because the deformation of the elastic member will also increase. A reasonable size for this distance can be obtained through a limited number of experiments and is not limited here. At the same time, arranging the elastic member between the second limiting panel 20 and the limiting plate 22 can avoid position interference with the clamping joint 102 and prevent the clamping joint 102 from being stuck in movement.

[0048] In one embodiment of the present invention, Figure 5 As shown, the side wall of the second limiting panel 20 is provided with a guide window 20c communicating with the inner cavity, and part of the structure of the limiting plate 22 passes through the guide window 20c to be exposed to the inner cavity, and the limiting plate 22 abuts against the inner wall of the guide window 20c.

[0049] In this embodiment, a guide window 20c is provided on the side of the second limiting panel 20 away from the guide rod 201, and the opening shape of the guide window 20c is set to be square. The partial structure of the end of the limiting plate 22 away from the two reserved holes is penetrated by the guide window 20c so that it is exposed in the inner cavity. In the assembled state, the limiting plate 22 can abut the inner wall of the guide window 20c.

[0050] In one embodiment of the present invention, the elastic member is configured as a spring 202 , and both the second limiting panel 20 and the limiting plate 22 are provided with spring positioning columns 203 , and both ends of the spring 202 accommodate the spring positioning columns 203 .

[0051] In this embodiment, the elastic member is configured as a spring 202. Compared to structures such as elastic arms, the spring 202 has a wider range of options, making it easier to select a model of spring 202 suitable for the quick-release structure. Two spring positioning posts 203 are provided on both the second limiting panel 20 and the limiting plate 22. Each spring positioning post 203 of the second limiting panel 20 is aligned with a spring positioning post 203 of the limiting plate 22. Each spring 202 has two opposing spring positioning posts 203 at each end. The spring positioning posts 203 not only facilitate the limited installation of the spring 202, but also guide the deformation of the spring 202, preventing the spring 202 from deforming along non-axial directions and avoiding the problem of insufficient force on the limiting plate 22. It is understandable that there is no limit on the number of springs 202 and spring positioning posts 203, and actual needs can be met.

[0052] The present invention also proposes a combination cabinet, which can be a small shoe cabinet or a large combination cabinet for use in the kitchen. There is no limitation here, as long as it can connect multiple combination cabinets. The combination cabinet includes at least two cabinet bodies and at least one quick-release structure. The cabinet body is provided with a receiving space and a receiving slot connected to the receiving space. The first mounting seat is limited to the receiving slot of one cabinet body, and the second mounting seat is limited to the receiving slot of the other cabinet body. It is ensured that the first mounting seat and the second mounting seat of the same quick-release structure are arranged in alignment. The combination cabinet has an assembled state. In the assembled state, the quick-release structure is in an assembly state. At this time, the two combination cabinets are assembled and fixed. If the assembled state of the cabinet body needs to be released, the cabinet body can be moved so that the card connector 102 passes through the second limiting section. No additional disassembly tools are required for disassembly. The specific structure of the quick-release structure refers to the above embodiment. Since the combination cabinet adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0053] The above are only preferred embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
