Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example

[0023] Depend on Figure 1-4 Provided is a filter disassembly and assembly mechanism for an air conditioning box of a fresh air system, comprising an air conditioning box filter body 1;

[0024] At least two sets of spring engaging mechanisms 2 are assembled on the outer periphery of the air conditioning box filter body 1;

[0025] The spring engaging mechanism 2 comprises a base 20, a limit block 21 is installed in the middle section of one side of the base 20, the limit block 21 forms a rectangular cavity and two sliders 22 are slidably arranged in the cavity, the two sliders 22 are respectively located at the two ends of the limit block 21 and a compression spring 23 is installed on the inner side of the two sliders 22;

[0026] One side of the base 20 is also equipped with two blocks 201 , which are located at both ends of one side of the base 20 and have cavities formed therein. The other ends of the two sliders 22 are respectively inserted into the cavities of the blocks 201 on the same side.

[0027] In this embodiment, the handle 27 is first pulled outward, and through the two connecting rods 25 rotatably connected to the handle 27 and the two first mounting plates 24 rotatably connected on one side of the two connecting rods 25, when the handle 27 moves outward, the two sliders 22 are driven to slide inward at the same time, and the compression spring 23 installed on the inner side is squeezed, so that the compression spring 23 is in a taut state, and then the clamping ring 11 set on one side of the air-conditioning box filter body 1 is aligned with the rectangular opening 28 set above the clamping block 201 and inserted, and then the clamping ring 11 is released. When hand 27 is pulled, the elastic force of compression spring 23 and external tension are used to make the taut compression spring 23 expand outward and push the slider 22 on one side to slide toward block 201, so that one end of block 201 is inserted into the snap ring 11 in rectangular opening 28 for snapping and fixing, thus completing the installation of air-conditioning box filter body 1. When it is to be disassembled, only the handle 27 needs to be pulled again to make the slider 22 cancel the limit on the snap ring 11, so that the air-conditioning box filter body 1 can be easily disassembled, thereby reducing the maintenance time and the maintenance cost.

[0028] It should be noted that the two sets of spring locking mechanisms 2 need to be installed inside the air conditioning box, so that the air conditioning box filter body 1 can be assembled between the two sets of spring locking mechanisms 2, which is convenient for quick disassembly and installation.

[0029] Specifically, refer to Figure 1 One side of the limit block 21 is provided with two openings, and one side of the two sliders 22 is equipped with two first mounting plates 24. The two first mounting plates 24 on the same side are respectively located within the travel range of the opening on one side of the limit block 21. A connecting rod 25 is connected between the two first mounting plates 24 on the same side through a rotating shaft. The two connecting rods 25 are arranged opposite to each other and a handle 27 is installed between the two connecting rods 25.

[0030] In this embodiment, the two ends of the connecting rod 25 are respectively connected to the two first mounting plates 24 and the two second mounting plates 26 through a rotating shaft. When the handle 27 drives the connecting rod 25, the other end of the connecting rod 25 will drive the slider 22 to move. At the same time, through the restriction of the opening on one side of the limit block 21, the moving distance of the slider 22 is affected by the size of the opening stroke range.

[0031] Specifically, refer to Figure 1-2 Two second mounting plates 26 are respectively installed on both sides of the handle 27, and the two second mounting plates 26 on the same side are connected to the connecting rod 25 on the same side through a rotating shaft.

[0032] In this embodiment, two second mounting plates 26 are distributed and installed on both sides of the handle 27, and the two connecting rods 25 are connected to the two second mounting plates 26 on the same side through the rotating shaft.

[0033] Specifically, refer to Figure 1 One side of the limit block 21 is equipped with two positioning blocks 211 , and one end of the handle 27 is sleeved in the two positioning blocks 211 .

[0034] In this embodiment, one end of the handle 27 is hollowed out, and the two positioning blocks 211 are just sleeved by one end of the handle 27 to limit the handle 27 .

[0035] Specifically, refer to Figure 2 A stop block 212 is installed in the cavity of the limit block 21, and the other ends of the two compression springs 23 are hooked with one side of the stop block 212 respectively.

[0036] In this embodiment, one end of the two compression springs 23 is hooked with one end of the stop block 212 , and the stop block 212 can limit the two compression springs 23 .

[0037] Specifically, refer to Figure 3-4 Two clamping rings 11 are respectively installed on both sides of the air conditioning box filter body 1, and a rectangular opening 28 is provided on one side of the clamping block 201, and the clamping ring 11 is inserted into the rectangular opening 28.

[0038] In this embodiment, the two clamping rings 11 arranged on both sides of the air-conditioning box filter body 1 are of detachable design. By aligning the clamping ring 11 with the rectangular opening 28, the handle 27 can be loosened to allow one end of the slider 22 to be inserted into the clamping ring 11, thereby limiting the position of the air-conditioning box filter body 1.

[0039] When the user uses the device, he first pulls the handle 27 outward, and through the two connecting rods 25 rotatably connected to the handle 27 and the two first mounting plates 24 rotatably connected to one side of the two connecting rods 25, when the handle 27 moves outward, the two sliders 22 are driven to slide inward at the same time, and the compression spring 23 installed on the inner side is squeezed, so that the compression spring 23 is in a taut state, and then the clamping ring 11 set on one side of the air conditioner filter body 1 is aligned with the rectangular opening 28 set above the clamping block 201 The filter body 1 of the air conditioner box is installed in the position where the filter 1 is fixed. When the filter 1 is to be removed, the handle 27 can be pulled again to allow the slider 22 to cancel the limit on the retaining ring 11, thereby easily removing the filter body 1 of the air conditioner box.
