[0035] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0036] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0037] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0038] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0039] The quick-release device provided in the embodiment of the present application is installed between two objects that need to be assembled together, and is used to realize convenient disassembly and assembly between the two objects. The application scenarios of the quick-release device provided in the embodiment of the present application include but are not limited to: the quick-release device is installed on a display to connect the display body and the mounting seat; the quick-release device is installed on a spliced ​​bracket to connect two mutually spliced ​​bracket units; the quick-release device is installed on a lamp to connect the lamp body and the mounting seat.

[0040] Please also read Figures 2 to 4 , the quick release device provided in the embodiment of the present application is now described. The quick release device includes a first connecting member 1, a second connecting member 2 and a third connecting member 3, wherein the first connecting member 1 is connected to a first object, and the second connecting member 2 is connected to a second object. A hook beam 11 is provided on the first connecting member 1, and a hook holding body 21 is provided on the second connecting member 2. The second connecting member 2 has a first state and a second state relative to the first connecting member 1 in a first direction. In the first state, the hook holding body 21 is hooked with the hook beam 11 and mutually restricts movement in the second direction. In the second state, the hook holding body 21 is disengaged from the hook beam 11 and is allowed to move relative to each other in the second direction. The first direction and the second direction are perpendicular to each other. There is a force between the third connecting member 3 and the second connecting member 2, and the force can switch the second connecting member 2 from the second state to the first state.

[0041] By using the cooperation between the hook beam 11 and the hook body 21, the movement of the first connection member 1 and the second connection member 2 in the second direction can be restricted. Moreover, since the hook body 21 is hooked with the hook beam 11 in the first state, the hook body 21 is separated from the hook beam 11 and is allowed to move relative to each other in the second direction in the second state, that is, when the position state of the first connection member 1 relative to the second connection member 2 is switched from the first state to the second state, the hook body 21 will be separated from the hook beam 11. Therefore, on the basis of the cooperation between the hook beam 11 and the hook body 21, the force generated between the third connection member 3 and the second connection member 2 is used to switch the second connection member 2 from the second state to the first state, thereby restricting the second connection from being in the second state in an unexpected situation.

[0042] When disassembly is required, it is only necessary to apply force to the second connecting member 2 to move the second connecting member 2 along the first direction and switch from the first state to the second state. At this time, the hook body 21 is disengaged from the hook beam 11, and the second connecting member 2 can move along the second direction, so that the first connecting member 1 can be disassembled from the second connecting member 2.

[0043] Compared with the prior art, the quick-release device provided in the present application is based on the cooperation between the first connecting member 1 and the second connecting member 2 through the hook beam 11 and the hook holding body 21. By setting the third connecting member 3, a force is generated between the third connecting member 3 and the second connecting member 2 so that the hook beam 11 and the hook holding body 21 are reliably hooked and held, thereby avoiding accidental separation of the hook beam 11 and the hook holding body 21, thereby improving the reliability of assembly. Moreover, when disassembling, it is only necessary to push the second connecting member 2 hard to detach it from the first connection. The entire disassembly and assembly process is simple and quick, and there is no need to use a button structure or additional auxiliary tools, thereby improving the disassembly and assembly efficiency.

[0044] The first connecting member 1 is fixedly connected to the first object, and the methods of fixed connection include but are not limited to bolting, bonding, and welding. Similarly, the second connecting member 2 is fixedly connected to the second object, and the methods of fixed connection include but are not limited to bolting, bonding, and welding.

[0045] The end surface of the first connecting member 1 used to cooperate with the second connecting member 2 is assumed to be the first matching surface 10 , and the end surface of the second connecting member 2 used to cooperate with the first connecting member 1 is assumed to be the second matching surface 20 .

[0046] In another embodiment of the present application, please refer to Figure 2 The third connecting member 3 is arranged between the first connecting member 1 and the second connecting member 2, and the third connecting member 3 is in contact with the first connecting member 1 (specifically the first mating surface 10), the second connecting member 2 is provided with a first magnetic component 22, and the third connecting member 3 is provided with a second magnetic component 30, the first magnetic component 22 and the second magnetic component 30 are arranged side by side in the first direction, and the magnetic properties of the first magnetic component 22 and the second magnetic component 30 are the same.

[0047] The first connecting member 1 , the second connecting member 2 and the third connecting member 3 are all plate-shaped structures, and the first connecting member 1 , the third connecting member 3 and the second connecting member 2 are stacked in sequence.

[0048] The second connecting member 2 is provided with a second mounting groove, and the first magnetic component 22 can be placed in the second mounting groove. The third connecting member 3 is provided with a third mounting groove, and the second magnetic component 30 can be placed in the third mounting groove.

[0049] Two groups of first magnetic components 22 are arranged at intervals along the second direction on the second connecting member 2, and correspondingly, two groups of second magnetic components 30 are arranged at intervals along the second direction on the third connecting member 3, and each group of first magnetic components 22 corresponds to each group of second magnetic components 30 in the first direction. It should be noted that each group of first magnetic components 22 and each group of second magnetic components 30 corresponding thereto have the same magnetic properties.

[0050] A magnetic component with the same magnetic properties is arranged between the second connecting member 2 and the third connecting member 3. By utilizing the mutual repulsion effect of the magnetic components with the same magnetic properties, the second connecting member 2 and the third connecting member 3 tend to move away from each other in the first direction. Since the third connecting member 3 is in contact with the first connecting member 1, it is equivalent to the first connecting member 1 and the second connecting member 2 tending to move away from each other in the first direction, thereby enabling the second connecting member 2 to switch from the second state to the first state.

[0051] In another embodiment of the present application, the third connecting member 3 is arranged between the first connecting member 1 and the second connecting member 2, and the third connecting member 3 is in contact with the first connecting member 1 (specifically the first mating surface 10), and an elastic member is provided between the second connecting member 2 and the third connecting member 3, and the expansion and contraction direction of the elastic member is the first direction, thereby also making the first connecting member 1 and the second connecting member 2 tend to move away from each other in the first direction.

[0052] In another embodiment of the present application, the elastic member may specifically be a spring, a metal spring or an elastic block made of an elastic material.

[0053] In another embodiment of the present application, please refer to Figure 2 and Figure 3 , the cooperation between the hook beam 11 and the hook holding body 21 is similar to the cooperation between the hanger and the clothes drying rod. Specifically, the hook holding body 21 includes a connecting portion 210 and a hook portion 211, and the hook portion 211 is formed by bending one end of the connecting portion 210 toward the other end of the connecting portion 210, and the other end of the connecting portion 210 is connected to the second connecting member 2. The first connecting member 1 is provided with a through groove 12 that penetrates the first connecting member 1, and the two ends of the hook beam 11 are connected to the two side walls of the through groove 12, and when the first connecting member 1 is installed on the first object, there is a gap between the hook beam 11 and the first object, and the gap can be passed through by the hook portion 211 of the hook holding body 21. The hook holding body 21 penetrates the through groove 12, and the hook portion 211 passes through the gap, so that the hook holding body 21 is hung on the hook beam 11.

[0054] In other embodiments, the hook beam 11 can also be provided with connecting rods at both ends, the connecting rods are connected to the first connecting member 1, and the hook beam 11 is hung on the first connecting member 1 through the connecting rods, and the hook portion 211 of the hook holding body 21 passes through the hook beam 11 and is hooked on the hook beam 11.

[0055] The hook beam 11 is provided on the first connecting member 1 by opening a through groove 12 , so that the first connecting member 1 and the second connecting member 2 can be more compactly matched.

[0056] When the hook beam 11 is provided on the first connecting member 1 by opening a through groove 12, a contact block 13 is provided on the first mating surface 10 of the first connecting member 1. The contact block 13 is located in the through groove 12 and connected to the hook beam 11. The contact block 13, the hook beam 11 and the groove wall of the through groove 12 are jointly enclosed to form a hook groove 14. The hook groove 14 can only be inserted into the end of the hook portion 211, and the hook groove 14 plays a limiting role on the hook portion 211.

[0057] In another embodiment of the present application, please refer to Figure 3 , Figure 5 and Figure 6 A first inclined surface 2110 is provided on the hook portion 211, and a second inclined surface 110 is provided on the hook beam 11. When the hook holding body 21 moves to the process of the hook portion 211 and the hook beam 11 being hooked and engaged, when the displacement distance of the second connecting member 2 in the first direction is not enough, the first inclined surface 2110 on the hook portion 211 can slide along the second inclined surface 110 on the hook beam 11 to the hook groove 14, which is conducive to the hook portion 211 being smoothly placed in the hook groove 14.

[0058] In another embodiment of the present application, see Figure 2 and Figure 5 , the second connecting member 2 has the aforementioned second state and third state relative to the first connecting member 1 in the second direction. In the third state, the hooking body 21 and the hooking beam 11 are misaligned in the first direction. The "the hooking body 21 and the hooking beam 11 are misaligned in the first direction" described here means that when the hooking body 21 or the hooking beam 11 is moved in the first direction, the hooking body 21 cannot be hooked and matched with the hooking beam 11. A guide structure is provided between the second connecting member 2 and the third connecting member 3, and the guide structure is used to provide a guide for the movement of the second connecting member 2 in the second direction.

[0059] The process of hooking and cooperating between the hook beam 11 and the hook holding body 21 includes two processes: alignment and hooking. The second connecting member 2 moves from the third state to the second state along the second direction, and the hook holding body 21 is aligned with the hook beam 11 in the first direction. The second connecting member 2 continues to move from the second state to the first state along the first direction, and the hook holding body 21 is hooked with the hook beam 11. The process of unhooking the hook beam 11 from the hook holding body 21 can be deduced in reverse. The description of "the hook holding body 21 and the hook beam 11 are aligned in the first direction" here means that when the hook holding body 21 or the hook beam 11 is moved in the first direction, the hook holding body 21 can be hooked and cooperated with the hook beam 11.

[0060] By providing a guide structure between the second connecting member 2 and the third connecting member 3 , the movement of the second connecting member 2 in the second direction can be limited.

[0061] In another embodiment of the present application, please refer to Figure 2The guide structure includes a slideway 23 and a slide bar 31 respectively arranged on the second connecting member 2 and the third connecting member 3, and the slide bar 31 can slide and cooperate with the slideway 23 along the second direction.

[0062] An insertion groove 24 is provided on the second mating surface 20 of the second connecting member 2 for the third connecting member 3 to be inserted. The cross-section of the insertion groove 24 in the first direction is "U"-shaped. Slide grooves 230 are provided on the inner walls on both sides of the insertion groove 24 to form a slideway 23. The third connecting member 3 is inserted into the insertion groove 24 along the second direction, and the slide bar 31 is inserted into the slide groove 230. This can provide a guiding effect on the movement of the second connecting member 2 in the second direction, and can avoid the second connecting member 2 and the third connecting member 3 from being detached to increase the assembly steps.

[0063] It should be added that the height of the slide groove 230 on the slide 23 in the first direction is greater than the height of the slide bar 31, and the height difference between the two can at least ensure that in the second state, the hook portion 211 will not abut against the hook beam 11 when moving along the second direction, that is, the lowest end of the hook portion 211 is level with the top end of the hook beam 11.

[0064] In addition, a through slot 32 is provided on the third connection, through which the hook body 21 passes, and the hook body 21 passes through the third connection member 3 through the through slot 32 to cooperate with the hook beam 11 on the first connection member 1. Moreover, the width of the through slot 32 in the second direction is greater than the width of the hook body 21, and the width difference between the two can at least ensure that in the third state, when the hook portion 211 moves along the first direction, it will not abut against the hook beam 11.

[0065] In another embodiment of the present application, please refer to Figure 2 A fixing structure for fixing the first connecting member 1 and the third connecting member 3 is provided between the third connecting member 3 and the first connecting member 1. Fixing the third connecting member 3 and the first connecting member 1 by the fixing structure can improve the stability of the overall structure of the quick release device.

[0066] In another embodiment of the present application, see Figure 2 The fixing structure includes a third magnetic component 15 and the aforementioned second magnetic component 30, the third magnetic component 15 is arranged on the first connecting member 1, the second magnetic component 30 and the third magnetic component 15 are arranged side by side in the first direction, and the second magnetic component 30 and the third magnetic component 15 have opposite magnetic properties. The first connecting member 1 and the third connecting member 3 can be fixed by using two sets of magnets with opposite magnetic properties.

[0067] The first connector 1 is provided with a first mounting groove for placing the third magnetic components 15. The number of the third magnetic components 15 corresponds to the number of the second magnetic components 30, and the third magnetic components 15 correspond to the second magnetic components 30 in the first direction.

[0068] In another embodiment of the present application, please continue to refer to Figure 2 A limiting structure is provided between the first connecting member 1 and the third connecting member 3 , and the limiting structure is used to limit the movement of the third connecting member 3 relative to the first connecting member 1 along the second direction.

[0069] During the switching process of the second connecting member 2 from the second state and the third state, it needs to move along the second direction. At the same time, in order to ensure that the guiding structure can provide guiding effect on the movement of the second connecting member 2 in the second direction, a limiting structure is set to limit the third connecting member 3 to follow the movement of the second connecting member 2 in the second direction.

[0070] In another embodiment of the present application, please continue to refer to Figure 2 The limiting structure includes a limiting block 33 and a limiting groove 16. The limiting block 33 is arranged on the third connecting member 3, and the limiting groove 16 is arranged on the first connecting member 1. The limiting block 33 can be inserted into the limiting groove 16 along the first direction. When the third connecting member 3 is attached to the first connecting member 1, the limiting block 33 is inserted into the limiting groove 16, thereby limiting the movement of the third connecting member 3 along the second direction.

[0071] In practical applications, the second connecting member 2 and the third connecting member 3 are pre-assembled into a whole. When the first object and the second object are disassembled and assembled using the quick-release device provided in the embodiment of the present application, it is only necessary to assemble the whole with the first connecting member 1.

[0072] The assembly process of the second connecting member 2 and the third connecting member 3: the first magnetic component 22 is installed in the second installation groove of the second connecting member 2, the second magnetic component 30 is installed in the third installation groove of the third connecting member 3, the third connecting member 3 is inserted into the insertion groove 24 along the second direction, and the slide bar 31 is inserted into the slide groove 230 of the slide rail 23, and finally the connecting part 210 of the hook body 21 is passed through the through groove 32 of the third connecting member 3 and installed on the second connecting member 2.

[0073] The assembly process of the quick release device: the third magnetic component 15 is installed in the first installation groove of the first connecting member 1, and the second connecting member 2 and the third connecting member 3 are integrally moved closer to the first connecting member 1 until the third connecting member 3 is fitted with the first connecting member 1. At the same time, the limit block 33 on the third connecting member 3 is inserted into the limit groove 16, the second magnetic component 30 is fixed to the third magnetic component 15 by magnetic attraction, and the hook body 21 is inserted into the through groove 12. Then, the second connecting member 2 is pressed hard in the first direction to make the second connecting member 2 approach the first connecting member 1, and it is in the third state at this time. Then, the second connecting member 2 is pushed in the second direction until the hook portion 211 is aligned with the hook beam 11 (hook groove 14), and it is in the second state at this time. Finally, the second connecting member 2 is released, and under the repulsive force of the first magnetic component 22 and the second magnetic component 30, the second connecting member 2 is pushed away from the first connecting member 1, and the hook portion 211 is hooked with the hook beam 11, and it is in the first state at this time.

[0074] The disassembly process of the quick-release device can be deduced in reverse, and will not be repeated here.
