[0041] The buckle self-locking structure according to some embodiments of the present application comprises a fixing member 1 and a buckle member 2. The fixing member 1 comprises a fixing body part 11 and a protruding limiting part 12, and a plug-in space 10 is formed between the protruding limiting part 12 and the fixing body part 11. The fixing body part 11 is further provided with a locking hole 110. The buckle member 2 is provided with a plug-in part 211 and an elastic locking part 212. The plug-in direction of the plug-in part 211 is perpendicular to the elastic deformation direction of the elastic locking part 212. The plug-in part 211 is adapted to be inserted into the plug-in space 10, so that the plug-in part 211 is limitedly matched with the protruding limiting part 12. The elastic locking part 212 is adapted to be inserted into the locking hole 110, so that the elastic locking part 212 is limitedly matched with the fixing body part 11. Thus, the self-locking fixed matching effect between the fixing member 1 and the buckle member 2 is realized.

[0042] For example, referring to Figures 1 to 6 As shown in the drawings, in an embodiment of the present application, the buckle self-locking structure is applied to a shelf 100. The shelf 100 can comprise a support column 101 and a shelf plate body 102. At least one set of buckle self-locking structures is arranged on the shelf. Specifically, the support column 101 is provided with the fixing member 1 of the buckle self-locking structure, and the shelf plate body 102 is provided with the buckle member 2 of the buckle self-locking structure (the fixing member 1 is part of the structure of the support column 101, and the buckle member 2 is part of the structure of the shelf plate body 102). During the matching assembly of the support column 101 and the shelf plate body 102, the self-locking fixed matching effect between the fixing member 1 and the buckle member 2 enables the support column 101 and the shelf plate body 102 to be fixedly assembled without the need for connecting members such as bolts and screws.

[0043] In addition, in other embodiments, the buckle self-locking structure can be arranged on the shelf in the form that the support column 101 is provided with the buckle member 2 of the buckle self-locking structure, and the shelf plate body 102 is provided with the fixing member 1 of the buckle self-locking structure.

[0044] It should be noted that in some other embodiments of the present application, the buckle self-locking structure can also be independently arranged. That is, the shelf 100 comprises a support column 101, a shelf plate body 102 and at least one set of buckle self-locking structures. The buckle self-locking structure comprises a fixing member 1 and a buckle member 2. One of the fixing member 1 and the buckle member 2 is assembled on the support column 101, and the other of the fixing member 1 and the buckle member 2 is assembled on the shelf plate body 102. The fixing member 1, the buckle member 2, the support column 101 and the shelf plate body 102 are all independent parts. The support column 101 and the fixing member 1 or the buckle member 2 form an integral whole by assembly, and the shelf plate body 102 and the buckle member 2 or the fixing member 1 form an integral whole by assembly.

[0045] It should be noted that the following embodiments are described by taking the fixing member 1 provided with the buckling self-locking structure and the placing plate body 102 provided with the buckling member 2 as examples, but the present application is not limited thereto.

[0046] Referring to Figure 1 , the X direction shown in Figure 1 is the length direction of the shelf 100, the Y direction is the width direction of the shelf 100, and the Z direction is the height direction of the shelf 100. In combination with Figures 3 to 6 , the insertion direction of the insertion part 211 is configured to be arranged along the length direction of the support column 101, and the elastic deformation direction of the elastic locking part 212 is configured to be arranged along the thickness direction of the support column 101. It should be understood that the X direction shown in Figure 3 is the thickness direction of the support column 101, the Y direction is the width direction of the support column 101, and the Z direction is the length direction of the support column 101.

[0047] In combination with Figures 1 to 6 , the fixing body part 11 of the fixing member 1 can be part of the support column 101, wherein the protruding limiting part 12 can include a first limiting plate body 121 and at least one second limiting plate body 122, and the second limiting plate body 122 is connected perpendicularly between the first limiting plate body 121 and the fixing body part 11 to form a strip-shaped groove 10a. For example Figure 4 , in this embodiment, the protruding limiting part 12 includes one first limiting plate body 121 and two second limiting plate bodies 122, and the two second limiting plate bodies 122 are connected perpendicularly between the first limiting plate body 121 and the fixing body part 11, so that two insertion spaces 10 configured as strip-shaped grooves 10a are formed in the width direction of the support column 101, i.e. the two strip-shaped grooves 10a are arranged in sequence in the width direction of the support column 101.

[0048] , the strip-shaped groove 10a extends along the height direction of the support column 101, and in the width direction of the support column 101, the opening of one strip-shaped groove 10a is arranged towards the left side, and the opening of the other strip-shaped groove 10a is arranged towards the right side, i.e. in the arrangement direction of the two strip-shaped grooves 10a, the two strip-shaped grooves 10a are arranged back to back. It should be understood that the two strip-shaped grooves 10a are arranged in sequence in the width direction of the support column 101, and the arrangement direction can also be understood as the width direction of the support column 101.

[0049] , and referring to Figure 6As shown, the buckling member 2 can include a first plate body 21, which is provided with a plug-in notch 210 configured as a "U" type, and a part of the edge of the plug-in notch 210 constitutes a plug-in portion 211 of the buckling member 2, wherein the plug-in portion 211 is formed with two sub-plug-in portions 2111 configured as plate shapes. In the process of assembling the support column 101 and the storage plate body 102 (i.e. in the process of assembling the fixing member 1 and the buckling member 2), each sub-plug-in portion 2111 is respectively inserted into the corresponding strip-shaped groove 10a. In this way, in the thickness direction of the support column 101, the first limiting plate body 121 is located on the side of the sub-plug-in portion 2111 away from the fixed main body portion 11, i.e. the sub-plug-in portion 2111 is clamped between the first limiting plate body 121 and the fixed main body portion 11. Therefore, when the plug-in portion 211 of the buckling member 2 is plugged into the plug-in space 10 of the fixing member 1 in the thickness direction of the support column 101, the relative position of the fixing member 1 and the buckling member 2 can be limited, i.e. the movement of the storage plate body 102 relative to the support column 101 in the thickness direction of the support column 101 is limited.

[0050] At the same time, when the two sub-plug-in portions 2111 configured as plate shapes are respectively inserted into the two plug-in spaces 10 configured as strip-shaped grooves 10a, in the width direction of the support column 101, when one sub-plug-in portion 2111 abuts against the groove bottom surface of the corresponding strip-shaped groove 10a, the movement of the storage plate body 102 relative to the support column 101 in the width direction of the support column 101 towards the left side is limited, and when the other sub-plug-in portion 2111 abuts against the groove bottom surface of the corresponding strip-shaped groove 10a, the movement of the storage plate body 102 relative to the support column 101 in the width direction of the support column 101 towards the right side is limited. Therefore, when the storage plate body 102 and the support column 101 of the shelf 100 are assembled by the buckling and self-locking structure, when the plug-in portion 211 of the buckling member 2 is plugged into the plug-in space 10 of the fixing member 1, at least the movement of the storage plate body 102 relative to the support column 101 in the thickness direction and the width direction of the support column 101 is limited.

[0051] It needs to be explained that in some embodiments of the present application, the number of plug-in spaces 10 is configured to be multiple, and the plug-in part 211 is configured to have multiple sub-plug-in parts 2111, each of which is plugged and matched with a corresponding plug-in space 10, and the arrangement direction of the multiple plug-in spaces 10 is perpendicular to the plug-in direction and the elastic deformation direction. In this way, in the plugged and matched state of the buckling piece 2 and the fixing piece 1, the relative position relationship between the buckling piece 2 and the fixing piece 1 is further limited. Taking the buckling piece 2 applied to the storage plate body 102 and the fixing piece 1 applied to the support column 101 as an example, in the case that the multiple sub-plug-in parts 2111 are plugged and matched with the corresponding plug-in spaces 10, the buckling piece 2 is limited and matched with the fixing piece 1 through the multiple sub-plug-in parts 2111, thereby reducing the risk of the storage plate body 102 rotating around the length direction of the support column 101, so as to further improve the stability of the shelf 100.

[0052] In addition, the first plate body 21 is further provided with an elastic locking part 212 configured as an elastic sheet 2120, when the elastic sheet 2120 is adapted to extend into the locking hole 110 provided in the fixing main body part 11, part of the structure of the elastic sheet 2120 is located in the locking hole 110, and the inner circumferential wall of the locking hole 110 and the elastic sheet 2120 are limited and matched, thereby limiting the relative position of the buckling piece 2 and the fixing piece 1. The elastic deformation direction of the elastic sheet 2120 is perpendicular to the plug-in direction of the plug-in part 211, in the embodiment, the plug-in direction of the plug-in part 211 is parallel to the length direction of the support column 101, and the elastic deformation direction of the elastic locking part 212 is parallel to the thickness direction of the support column 101. Therefore, when the elastic locking part 212 extends into the locking hole 110 of the fixing piece 1, at least the movement of the storage plate body 102 relative to the support column 101 in the length direction of the support column 101 is limited when the storage plate body 102 and the support column 101 are assembled by the buckling and self-locking structure.

[0053] It needs to be explained that in the above embodiment, the first plate body 21 of the buckling piece 2 is provided with the plug-in notch 210 to form the plug-in part 211, and is also provided with the elastic locking part 212 configured as the elastic sheet 2120, so that the plug-in part 211 and the elastic locking part 212 are integrally formed on the first plate body 21 of the buckling piece 2. For example, the plug-in notch 210 is punched out in the first plate body 21 to form the plug-in part 211, and the elastic sheet 2120 is punched out, so that the plug-in part 211 and the elastic locking part 212 both have high structural strength.

[0054] Referring to Figure 6As shown, in some embodiments of the present application, the buckling member 2 can further comprise a second plate body 22, which is connected to the first plate body 21 and forms an included angle between the first plate body 21 and the second plate body 22. The second plate body 22 is provided with an avoiding gap 220 to form a circumferential limiting portion 221, and the protruding limiting portion 12 is adapted to pass through the avoiding gap 220. When the fixing member 1 and the buckling member 2 are assembled, the circumferential limiting portion 221 is adapted to abut and limit the protruding limiting portion 12, thereby further limiting the relative position relationship between the fixing member 1 and the buckling member 2, improving the connection reliability of the fixing member 1 and the buckling member 2, and reducing the risk of separation of the fixing member 1 and the buckling member 2.

[0055] For example, the second plate body 22 and the first plate body 21 can be an integral part, which is bent to form an included angle between the first plate body 21 and the second plate body 22. Figure 6 As shown, the second plate body 22 is perpendicular to the first plate body 21. The second plate body 22 is provided with an avoiding gap 220 configured as a "U" shape, and the avoiding gap 220 is in communication with the insertion gap 210. When the insertion portion 211 of the buckling member 2 is inserted into the insertion space 10 of the fixing member 1, the protruding limiting portion 12 passes through the avoiding gap 220, and the circumferential limiting portion 221 formed by the edge structure of the avoiding gap 220 is arranged around the protruding limiting portion 12, and the circumferential limiting portion 221 is adapted to abut and limit the protruding limiting portion 12, thereby limiting the relative position relationship between the fixing member 1 and the buckling member 2, improving the connection reliability of the fixing member 1 and the buckling member 2, reducing the risk of separation of the fixing member 1 and the buckling member 2, and thus improving the stability of the shelf 100 using the buckling self-locking structure of the present application.

[0056] In combination with Figure 5 and Figure 6 As shown, when the buckling member 2 is applied to the commodity plate body 102, the first plate body 21 of the buckling member 2 is the side plate of the commodity plate body 102, and the second plate body 22 of the buckling member 2 is the bottom plate of the commodity plate body 102. In addition, in some embodiments of the present application, the fixing member 1 can further comprise a protruding support portion 3, which is arranged on the fixing main body portion 11 and is adapted to abut and limit the buckling member 2 along the insertion direction of the insertion portion 211.

[0057] For example, in the application of the support column 101 in the shelf 100, the protruding support part 3 can be arranged below the locking hole 110 in the length direction of the support column 101 (which can also be understood as the height direction of the shelf 100), and when the elastic locking part 212 extends into the height position of the locking buckle 2 relative to the fixed part 1, the protruding support part 3 abuts below the buckle 2, so that the protruding support part 3 has the effect of supporting the buckle 2. For example, in some embodiments of the present application, the second plate body 22 of the buckle 2 is adapted to abut and limit the protruding support part 3, thereby limiting the relative position of the buckle 2 in the length direction of the support column 101. Therefore, when the buckling self-locking structure is applied to the shelf 100, the design of the protruding support part 3 improves the support ability of the support column 101 to the display plate body 102, thereby facilitating the improvement of the carrying capacity of the display plate body 102.

[0058] In addition, referring to Figure 6 In some embodiments of the present application, the buckle 2 is provided with a plug-in gap 210 configured as a "U" shape to form a plug-in part 211, and the upper edge of the plug-in part 211 is adapted to abut and limit the protruding limiting part 12 when the plug-in part 211 is plug-in matched with the fixed part 1. In this way, the protruding limiting part 12 is not only used to limit the movement of the display plate body 102 in the thickness direction and the width direction of the support column 101 relative to the support column 101, but also used to limit the movement of the display plate body 102 in the length direction of the support column 101 downward relative to the support column 101. In some embodiments of the present application, in the length direction of the support column 101, the protruding limiting part 12 and the protruding support part 3 both play a supporting role to the display plate body 102, which improves the support ability of the support column 101 to the display plate body 102, thereby facilitating the improvement of the carrying capacity of the display plate body 102.

[0059] It should be noted that in some embodiments described above, for example, the buckle 2 is provided with a plug-in gap 210 configured as a "U" shape to form a plug-in part 211, and the plug-in space 10 is a strip-shaped groove 10a, so that the plug-in part 211 has two sub-plug-in parts 2111 configured as plates. By inserting the two sub-plug-in parts 2111 configured as plates into the two plug-in spaces 10 configured as strip-shaped grooves 10a respectively, the plug-in matching effect of the buckle 2 and the fixed part 1 is achieved.

[0060] However, the present application is not limited thereto. In some other embodiments of the present application, the buckle 2 can include a buckle main body part, and the plug-in part 211 includes a connecting body and a plug-in body, wherein the connecting body is connected between the buckle main body part and the plug-in body, and the plug-in body is spaced apart from the buckle main body part. Referring to Figure 4As shown, the protruding limiting part 12 includes a first limiting plate body 121 and two second limiting plate bodies 122, and the two second limiting plate bodies 122 are connected between the first limiting plate body 121 and the fixed main body part 11, wherein the two second limiting plate bodies 122 are in a spaced state, so that a plug-in space 10 is formed between the two second limiting plate bodies 122. In this way, when the plug-in body extends into the plug-in space 10, the first limiting plate body 121, the two second limiting plate bodies 122, and the fixed main body part 11 can all limit the plug-in body. And in the height direction of the protruding limiting part 12, the upper surface of the first limiting plate body 121 is also adapted to abut against the connecting body. It should be noted that the first plate body 21 mentioned in some of the above embodiments can be the buckle main body part of the buckle.

[0061] In some of the above embodiments, the elastic locking part 212 is configured as an elastic piece 2120. However, the present application is not limited thereto. In some other embodiments of the present application, for example, the elastic locking part 212 can include an elastic locking pin and an elastic driving member, and the elastic locking pin is movably assembled to the buckle main body part through the elastic driving member. It can also be understood that, under the action of the elastic driving member, the elastic locking pin can perform axial extension and retraction movement, so that the elastic locking pin can extend into the locking hole 110 provided in the fixed main body part 11.

[0062] It should be noted that, according to the buckle self-locking structure of the present application, the fixed part 1 is provided with a locking hole 110, and the buckle part 2 is provided with an elastic locking part 212. Under the driving action of the elastic force of the elastic locking part 212 itself, the elastic locking part 212 can automatically extend into the locking hole 110, so that the fixed part 1 and the buckle part 2 realize the function of self-locking. In this way, not only the assembly process is simplified, but also the complexity of operation is significantly reduced.

[0063] In addition, in some embodiments of the present application, the locking hole 110 is configured as a through hole, and the locking hole 110 has a first through opening and a second through opening which are communicated. The elastic locking part 212 is arranged to be able to enter the inside of the locking hole 110 through the first through opening, so as to realize the automatic locking function between the fixed part 1 and the buckle part 2. At the same time, the design of the second through opening allows the user to apply an external force to the elastic locking part 212 through the opening, so that the elastic locking part 212 is moved out of the locking hole 110, thereby releasing the locked state between the fixed part 1 and the buckle part 2, so that the two can be separated. Specifically, when the fixed part 1 and the buckle part 2 are in a locked state, the elastic locking part 212 enters the locking hole 110 from the first through opening side. Since the locking hole 110 is designed as a through hole, the user can apply force from the second through opening side opposite to the first through opening, so as to promote the elastic locking part 212 to exit from the locking hole 110, thereby achieving the effect of mutual unlocking of the fixed part 1 and the buckle part 2, so that the fixed part 1 and the buckle part 2 can be disassembled.

[0064] Referring to Figure 4 As shown in the drawings, in some embodiments of the present application, the fixed body part 11 is also provided with at least two locking holes 110, and these locking holes 110 are symmetrically arranged based on the protruding limiting part 12, which significantly improves the versatility of the fixed body part 11. For example, in combination with Figure 1 and Figure 3 As shown, when the storage plate body 102 is assembled with the support column 101 on the left side of the shelf 100, the elastic locking part 212 arranged on the left side of the storage plate body 102 extends into the locking hole 110 of the support column 101 on the left side; on the contrary, when the storage plate body 102 is assembled with the support column 101 on the right side of the shelf 100, the elastic locking part 212 arranged on the right side of the storage plate body 102 extends into the locking hole 110 of the support column 101 on the right side. Through this design, the fixing part 1 arranged in the support column 101 can flexibly adapt to support columns 101 in different positions, without the need to design different parts for the support column 101 arranged on the left side or the right side of the shelf 100, which not only reduces production costs, but also improves the versatility of the support column 101 and reduces the installation difficulty of the support column 101 and the storage plate body 102.

[0065] In summary, during the assembly process of the shelf 100 equipped with the locking and self-locking structure of the present application, the insertion part 211 of the locking part 2 is inserted into the insertion space 10 of the fixing part 1, which at least restricts the relative movement of the storage plate body 102 and the support column 101 in the thickness direction and the width direction of the support column 101, and when the elastic locking part 212 extends into the locking hole 110, it at least restricts the relative movement of the storage plate body 102 and the support column 101 in the length direction of the support column 101, thereby achieving the locking and fixing effect of the relative position relationship between the storage plate body 102 and the support column 101. Therefore, for the shelf 100 equipped with the locking and self-locking structure of the present application, no additional connecting parts are required during the assembly process of the shelf 100, which not only reduces the required parts of the shelf 100, thereby reducing the cost of the shelf 100, but also improves the assembly efficiency of the shelf 100.

[0066] In addition, the locking and self-locking structure can also be applied to products that need to be provided with the locking and self-locking structure. For example, the locking and self-locking structure is applied to a bed, which can include a bed leg column and a bed plate. The bed leg column is provided with the fixing part 1 of the locking and self-locking structure, and the bed plate is provided with the locking part 2 of the locking and self-locking structure. Through the fixed cooperation of the fixing part 1 and the locking part 2, the bed leg column and the bed plate are fixed and assembled without the need for connecting parts such as bolts and screws.

[0067] Any combination of the technical features in the above-described embodiments can be made, and for the sake of brevity, not all possible combinations are described, however, it is to be understood that the application embraces all such possible combinations.

[0068] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be pointed out that for ordinary skilled persons in the art, some modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
