[0034] Embodiment 1

[0035] Please refer to Figures 1 to 7 , this embodiment provides a double snap - type anti - detachment structure, including a first main body 1 and a second main body 2. The first main body 1 is provided with a first installation plane 11 and a first contact surface 12, the second main body 2 is provided with a second installation plane 21 and a second contact surface 22. An adapted insertion component is provided between the first contact surface 12 and the second contact surface 22, a limiting component is provided between the first installation plane 11 and the second installation plane 21, and the limiting component is connected with an unlocking component;

[0036] When the second installation plane 21 is attached to the first installation plane 11 and moved to the installation position along the installation direction, the first main body 1 and the second main body 2 are fixedly connected through the adapted insertion component, and the limiting component can limit the second installation plane 21 from moving along the first installation plane 11 in the disassembly direction;

[0037] When it is necessary to separate the first main body 1 and the second main body 2, the limiting component is released through the unlocking component, so that the second installation plane 21 can move along the first installation plane 11 in the disassembly direction.

[0038] In this embodiment, the first mounting plane 11 and the first contact surface 12 of the first body 1 are perpendicular to each other, and the second mounting plane 21 and the second contact surface 22 of the second body 2 are perpendicular to each other. When assembling the first body 1 and the second body 2, the first mounting plane 11 of the first body 1 is attached to the second mounting plane 21 of the second body 2. Then, the first body 1 or the second body 2 is moved along the mounting direction. When the first contact surface 12 contacts the second contact surface 22, the first body 1 and the second body 2 are fixed to each other through the plug-in assembly. To prevent the first body 1 or the second body 2 from moving in the reverse direction of the mounting direction, that is, the disassembly direction, causing the two to separate from each other, a limiting component is provided between the first mounting plane 11 and the second mounting plane 21. The limiting component will not affect the assembly process of the first body 1 and the second body 2. After the assembly is completed, it limits the two to prevent accidental separation of the first body 1 and the second body 2.

[0039] When it is necessary to separate the first body 1 and the second body 2, the limiting component can be released through the unlocking component, so that the first body 1 or the second body 2 can move in the disassembly direction, thereby realizing the separation of the two, which is very convenient.

[0040] Setting the limiting component between the first mounting plane 11 and the second mounting plane 21 can effectively utilize the space without adding additional structural parts, and can better save costs.

[0041] In one implementation, the structure of the limiting component is improved to ensure the reliability of the locking between the two bodies. Specifically, the limiting component includes a matching buckle 131 and a slot. The first mounting plane 11 is provided with two slots, and the two slots are mirror-symmetrically arranged on both sides along the mounting direction. Each slot is provided with a connecting piece 13. Each connecting piece 13 includes an inner end and an outer end. Each connecting piece 13 is connected to the slot wall of the slot through the inner end. The buckle 131 is arranged on the top surface of the outer end of the connecting piece 13, and the slot 211 is correspondingly arranged on the second mounting plane 21 of the second body 2;

[0042] The buckle 131 can be moved below the first mounting plane 11 through the unlocking component, so that the buckle 131 is disengaged from the slot 211.

[0043] In this embodiment, for the convenience of description, the two sides in the installation direction are defined as the left and right sides. Two slots are provided on the first installation plane 11, and the two slots are arranged mirror-symmetrically on the left and right sides in the installation direction. Each slot is provided with a connecting piece 13 arranged along the length direction of the slot. Each connecting piece 13 includes an inner end and an outer end. Among them, the end of each connecting piece 13 close to the other connecting piece is the inner end, and the end of each connecting piece 13 away from the other connecting piece 13 is the outer end. Each connecting piece 13 is connected to the slot wall of the slot on the first installation plane 11 through the inner end. A buckle 131 is provided on the top surface of the outer end of each connecting piece 13. Each of the two second installation planes 21 of the second body 2 is provided with a slot 211 corresponding to the two buckles 131.

[0044] When the first body 1 and the second body 2 are in the assembled state, the two buckles 131 are respectively inserted into the corresponding slots 211, thereby preventing the first body 1 and the second body 1 from moving in the disassembly direction, thus ensuring the reliability and stability of the connection between the first body 1 and the second body 2.

[0045] When it is necessary to separate the first body 1 and the second body 2, an external force is applied to the connecting piece 13 through the unlocking component, so that the connecting piece 13 is bent and deformed, and drives the buckle 131 to move towards the inside of the first body 1, so that the buckle 131 sinks below the first installation plane 11, thereby moving the buckle 131 out of the slot 211. At this time, the first body 1 and the second body 2 can move in the disassembly direction to realize the separation of the two.

[0046] In one embodiment, the structure of the buckle 131 is improved to facilitate the assembly of the first body 1 and the second body 2. Specifically, the buckle 131 is provided with a guiding inclined surface 132 on the side facing the installation direction.

[0047] In this embodiment, when assembling the first body 1 and the second body 2, in order to prevent the buckle 131 from affecting the relative movement between the first body 1 and the second body 2, the buckle 131 is provided with a guiding inclined surface 132 on the side facing the installation direction. When the first contact surface 12 of the first body 1 moves towards the second contact surface 22 of the second body 2, the second contact surface 22 can push the buckle 131 towards the inside of the first body 1 through the guiding inclined surface 132, and the buckle 131 is restricted inside the first body 1 through the second installation plane 21, thereby avoiding the interference of the buckle 131 on the assembly process. When the first body 1 and the second body 2 move to the installation position, the buckle 131 returns to its original position under the elastic force of the connecting piece 13 and is inserted into the corresponding slot 211 of the second installation plane 21 to realize the limit.

[0048] In one embodiment, the structure of the unlocking component is improved to ensure that it is easy to unlock the limiting component through the unlocking component. Specifically, the unlocking component includes a pressing piece 14, and the pressing piece 14 is connected to the outer end of the connecting piece 3.

[0049] In this embodiment, in order to facilitate the user to apply force to the connecting piece 13 to move the buckle 131 out of the card slot 211, the unlocking component specifically includes a pressing piece 14. The pressing piece 14 is connected to the outer end of the connecting piece 13. An external force can be applied to the outer end of the connecting piece 13 away from the second installation plane 2 through the pressing piece 14, so that the connecting piece 13 is bent and deformed, and drives the buckle 131 to move towards the inside of the first main body 1, so that the buckle 131 sinks below the first installation plane 11, and the buckle 131 can be moved out of the card slot 211. At this time, the first main body 1 and the second main body 2 can move along the disassembly direction to realize the separation of the two.

[0050] In one embodiment, the structure of the unlocking component is improved to ensure that it is easy to unlock the limiting component through the unlocking component. Specifically, a side slot is provided on the side surface of the first main body 1, and the side slot communicates with the slot, and the pressing piece 14 is arranged in the side slot.

[0051] In this embodiment, in order to reduce the adverse effects of the outside world on the pressing piece 14, a side slot is provided on each of the two side surfaces of the first main body 1. Each side slot communicates with the adjacent slot, and the pressing piece 14 is arranged in the side slot. The pressing piece 14 is arranged along the length direction of the side slot. The upper end of the pressing piece 14 is connected to the outer end of the connecting piece 13, and the pressing piece 14 and the side surface of the connecting piece 13 form an "L" - shaped structure.

[0052] By applying a force towards the inside of the first main body 1 to the pressing pieces 14 on both sides of the first main body 1, the pressing pieces 14 move towards the inside of the first main body 1. The pressing pieces 14 can drive the connecting piece 13 to bend and deform, drive the buckle 131 to move towards the inside of the first main body 1, so that the buckle 131 sinks below the first installation plane 11, thereby moving the buckle 131 out of the card slot 211. At this time, the first main body 1 and the second main body 2 can move along the disassembly direction to realize the separation of the two.

[0053] In one embodiment, the structure of the pressing piece 14 is improved to ensure the convenience of operating the unlocking component. Specifically, a pressing block 141 is provided at the end of the pressing piece 14 away from the connecting piece 13, and the pressing block 141 protrudes from the side surface of the first main body 1.

[0054] In this embodiment, in order to facilitate applying force to the pressing piece 14, a pressing block 141 is provided at one end of the pressing piece 14 away from the connecting piece 13. The pressing block 141 protrudes from the side surface of the first main body 1, thereby facilitating the user to position the pressing piece 14 and making it convenient for the user to perform a pressing action.

[0055] Preferably, the first mounting plane 11 of the first main body 1, the connecting piece 13, the buckle 131, the pressing piece 14, and the pressing block 141 are of an integrally formed structure, which can effectively reduce the use of structural parts and achieve better cost control.

[0056] In one embodiment, the structures of the first main body 1 and the second main body 2 are improved to facilitate the positioning of the first main body 1 and the second main body 2 and provide a better limiting effect. Specifically, the first mounting plane 11 is provided with a guiding groove 15 arranged along the mounting direction, and the second mounting plane 21 of the second main body 2 is provided with a guiding protrusion 25 corresponding to the guiding groove 15. When connecting the first main body 1 and the second main body 2, the guiding protrusion 25 can be inserted into the guiding groove 15.

[0057] In this embodiment, by providing a guiding groove 15 arranged along the mounting direction on the first mounting plane 11 of the first main body 1 and a guiding protrusion 25 corresponding to the guiding groove 15 on the second mounting plane 21 of the second main body 2, when assembling the first main body 1 and the second main body 2, the guiding protrusion 25 and the guiding groove 15 can be used for alignment installation. At the same time, the adapted guiding protrusion 25 and guiding groove 15 can limit the left and right side directions of the first main body 1 and the second main body 2, further ensuring the stability and reliability of the assembly of the first main body 1 and the second main body 2.

[0058] Preferably, the cross-sectional shape of the guiding groove 15 along the width direction is in a "T" shape, and the cross-section of the guiding protrusion 25 along the width direction is adapted to the cross-sectional shape of the guiding groove 15. After assembling the first main body 1 and the second main body 2, the adapted guiding protrusion 25 and guiding groove 15 can limit the up and down directions of the first main body 1 and the second main body 2, further ensuring the stability and reliability of the assembly of the first main body 1 and the second main body 2.
