[0022] The present invention will now be described in more detail with reference to the accompanying drawings. It should be noted that the description of the present invention with reference to the accompanying drawings is merely illustrative and not restrictive. Various embodiments can be combined with each other to form other embodiments not shown in the following description.

[0023] Please see Figures 1 to 3 The easily detachable connecting device provided by this utility model includes a connector 3, a first plug-in component 4, a second plug-in component 5, and a limiting component 6. The connecting device is suitable for fixing a first component 1 and a second component 2. The first component 1 has a first vertical mounting hole 11 and a first horizontal mounting hole 12 that are connected, and the second component 2 has a second vertical mounting hole 21 and a second horizontal mounting hole 22 that are connected.

[0024] The connector 3 has multiple connecting holes 31, and at least two connecting holes 31 overlap with the first vertical mounting hole 11 and the second vertical mounting hole 21 in the vertical direction; the first plug-in 4 has a first limiting hole 41, and part of the first plug-in 4 passes through one of the connecting holes 31 and is inserted into the first vertical mounting hole 11, and the first limiting hole 41 is aligned with the first horizontal mounting hole 12; the second plug-in 5 has a second limiting hole 51, and part of the second plug-in 5 passes through the other connecting hole 31 and is inserted into the second vertical mounting hole 21, and the second limiting hole 51 is aligned with the second horizontal mounting hole 22; the limiting member 6 includes a first limiting post 61, a second limiting post 62, and an elastic member 63, the elastic member 63 is fixed to both the first limiting post 61 and the second limiting post 62, and part of the first limiting post 61 can pass through the first horizontal mounting hole 12 and be inserted into the first limiting hole 41, and part of the second limiting post 62 can pass through the second horizontal mounting hole 22 and be inserted into the second limiting hole 51.

[0025] This utility model provides a connecting device that is easy to disassemble. By passing the first connector 4 through the connecting hole 31 and inserting it into the first vertical mounting hole 11, passing the second connector 5 through the connecting hole 31 and inserting it into the second vertical mounting hole 21, then passing the first limiting post 61 through the first horizontal mounting hole 12 and inserting it into the first limiting hole 41, and passing the second limiting post 62 through the second horizontal mounting hole 22 and inserting it into the second limiting hole 51, the first component 1 and the second component 2 can be fixed. By pulling out the first limiting post 61 and the second limiting post 62, and then pulling out the first connector 4 and the second connector 5, the first component 1 and the second component 2 can be disassembled. This connecting device is easy to install and disassemble and has high practicality.

[0026] It is conceivable that the connector 3 is made of a rigid material. Therefore, when fixing the first component 1 and the second component 2, the first connector 4 is passed through the connecting hole 31 and inserted into the first vertical mounting hole 11, and the second connector 5 is passed through the connecting hole 31 and inserted into the second vertical mounting hole 21. At this point, the first component 1, the second component 2, and the connector 3 can no longer move relative to each other. Next, the first limiting post 61 is passed through the first horizontal mounting hole 12 and inserted into the first limiting hole 41, and the second limiting post 62 is passed through the second horizontal mounting hole 22 and inserted into the second limiting hole 51. This restricts the axial movement of the first connector 4 and the second connector 5, thereby completely fixing the first component 1 and the second component 2. In addition, due to the presence of the elastic element 63, the first limiting post 61 will not detach from the first limiting hole 41, and the second limiting post 62 will not detach from the second limiting hole 51. When it is necessary to disassemble the first component 1 and the second component 2, the first limiting post 61 can be disengaged from the first limiting hole 41 and the second limiting post 62 can be disengaged from the second limiting hole 51 by manually or mechanically compressing the elastic element 63. At this time, the first connector 4 and the second connector 5 can be axially pulled out, thereby realizing the disassembly of the first component 1 and the second component 2.

[0027] It should be noted that the vertical direction is the axial direction of the first vertical mounting hole 11.

[0028] In addition, multiple connecting holes 31 are provided along the length of the connector 3, and different connecting holes 31 can fix the first component 1 and the second component 2 at different distances.

[0029] Specifically, the first connector 4 includes an integrally formed first snap-fit ​​portion 42 and a first plug-in portion 43. The diameter of the first snap-fit ​​portion 42 is larger than the diameter of the connecting hole 31. The first limiting hole 41 is located on the first plug-in portion 43, and the first plug-in portion 43 can pass through the connecting hole 31 and be inserted into the first vertical mounting hole 11. The second connector 5 includes an integrally formed second snap-fit ​​portion 52 and a second plug-in portion 53. The diameter of the second snap-fit ​​portion 52 is larger than the diameter of the connecting hole 31. The second limiting hole 51 is located on the second plug-in portion 53, and the second plug-in portion 53 can pass through the connecting hole 31 and be inserted into the second vertical mounting hole 21.

[0030] The first plug-in portion 43 is provided with a first limiting surface 44, the second plug-in portion 53 is provided with a second limiting surface 54, and the inner walls of at least two connecting holes 31 are provided with a third limiting surface 32. The first limiting surface 44 and the third limiting surface 32 abut against each other to align the first limiting hole 41 with the first horizontal mounting hole 12, and the second limiting surface 54 and the third limiting surface 32 abut against each other to align the second limiting hole 51 with the second horizontal mounting hole 22.

[0031] The first connector 4 and the second connector 5 have the same structure, so the following description will use the first connector 4 as an example. Since the diameter of the first snap-fit ​​part 42 is larger than the diameter of the connecting hole 31, when installed vertically downwards, the first snap-fit ​​part 42 can abut against the upper side of the connector 3, thereby restricting the vertical movement of the first connector 4. When the first snap-fit ​​part 42 abuts against the upper side of the connector 3, the first limiting hole 41 is exactly aligned with the first horizontal mounting hole 12.

[0032] In addition, the first limiting surface 44 extends along the vertical direction of the first plug-in portion 43. Therefore, when the first plug-in portion 43 is inserted into the connecting hole 31, the first limiting surface 44 can continuously abut against the third limiting surface 32, restricting the rotation of the first plug-in portion 43 and the first limiting hole 41, thereby facilitating the alignment of the first limiting hole 41 with the first horizontal mounting hole 12.

[0033] The first limiting post 61 and the second limiting post 62 are spaced apart, and the elastic member 63 is located between the first limiting post 61 and the second limiting post 62; the elastic member 63 is compressed or extended to change the distance between the first limiting post 61 and the second limiting post 62.

[0034] It is conceivable that during the process of fixing or disassembling the first component 1 and the second component 2, it is necessary to change the distance between the first limiting post 61 and the second limiting post 62. Specifically, the elastic element 63 can be a spring, leaf spring, or other elastic part. When the elastic element 63 is compressed, the distance between the first limiting post 61 and the second limiting post 62 decreases; when the elastic element 63 is extended, the distance between the first limiting post 61 and the second limiting post 62 increases.

[0035] To facilitate the compression of the elastic element 63, the limiting member 6 also includes two disassembly posts 64, which are respectively fixed to the first limiting post 61 and the second limiting post 62. The user can clamp the two disassembly posts 64 manually or with equipment to apply force to compress the elastic element 63, thereby facilitating the installation or removal of the limiting member 6.

[0036] The first limiting post 61 and the second limiting post 62 are cylindrical or cuboid in shape, and the first horizontal mounting hole 12, the second horizontal mounting hole 22, the first limiting hole 41, and the second limiting hole 51 are cylindrical or cuboid in shape.

[0037] It is conceivable that when the first limiting post 61 is cylindrical, the first horizontal mounting hole 12 and the first limiting hole 41 are also cylindrical. In this case, the first limiting post 61 can rotate around its axis to adjust the position of the disassembly post 64, thus facilitating the user to clamp the two disassembly posts 64 manually or with equipment at different workstations. When the first limiting post 61 is cuboid, the first horizontal mounting hole 12 and the first limiting hole 41 are also cuboid. In this case, the first limiting post 61 cannot rotate, resulting in better stability.

[0038] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
