An outer shell body 2 is arranged on the top of the bottom plate 1. A limit frame 3 is fixedly connected to the top of the bottom plate 1. A mounting plate 4 is fixedly connected to the bottom of the outer shell body 2. The rear end of the mounting plate 4 extends into the inner cavity of the limit frame 3 and is detachably connected to the inner cavity of the limit frame 3. An installation mechanism 5 is arranged in the inner cavity of the bottom plate 1;

[0025] The installation mechanism 5 includes positioning holes 501, which are opened on both sides of the top of the mounting plate 4. Accommodating grooves 502 are opened on both sides of the top of the inner cavity of the limit frame 3.

The bottom of the positioning block 503 extends into the inner cavity of the positioning hole 501 and is engaged with the inner cavity of the positioning hole 501.

[0026] As Figure 1As shown, the bottom plate 1 is used to support and fix the components at the top. After inserting the mounting plate 4 into the inside of the limit frame 3, it can limit the outer shell body 2 to a certain extent, preventing the outer shell body 2 from shifting in position on the top of the bottom plate 1. The mounting mechanism 5 can fix the mounting plate 4 inside the limit frame 3. Not only is the installation relatively convenient, but when it is necessary to disassemble and maintain the outer shell body 2, the outer shell body 2 can also be directly removed through the mounting mechanism 5, thereby saving manpower.

[0027] Embodiment 2

[0028] Referring to Figures 2-5 , this is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.

[0029] In this embodiment, a connecting rope 504 is fixedly connected to the top of the positioning block 503. A first spring 505 is sleeved on the surface of the connecting rope 504. The bottom of the first spring 505 is fixedly connected to the positioning block 503, and the top of the first spring 505 is fixedly connected to the top of the inner cavity of the receiving groove 502.

[0030] An activity groove 506 is opened on the front surface of the bottom plate 1. An activity plate 507 is slidably connected to the inner cavity of the activity groove 506. Auxiliary grooves 508 are opened on both sides of the back surface of the inner cavity of the activity groove 506. Connecting blocks 509 are fixedly connected to both sides of the back surface of the activity plate 507. The rear ends of the connecting blocks 509 extend into the inner cavity of the auxiliary groove 508 and are slidably connected to the inner cavity of the auxiliary groove 508.

[0031] A first guiding groove 510 is opened on the top of the activity plate 507. A second guiding groove 511 is opened on the top of the receiving groove 502. One end of the connecting rope 504 away from the positioning block 503 extends into the inner cavity of the auxiliary groove 508 and is fixedly connected to the connecting block 509. Guide wheels 512 are arranged in the inner cavities of the first guiding groove 510 and the second guiding groove 511. The connecting rope 504 is slidably connected to the surface of the guide wheels 512.

[0032] As Figures 2-5 shown, by pushing the activity plate 507, the connecting block 509 can cooperate with the connecting rope 504 and the guide wheels 512 to pull the positioning block 503, so that it moves upward inside the receiving groove 502. During the movement of the positioning block 503, the first spring 505 will be deformed due to the pressure, and the restoring elastic force of the first spring 505 can reset the positioning block 503, enabling it to enter the positioning hole 501 and engage with it, thereby achieving the purpose of installing the outer shell body 2.

[0033] Embodiment 3

[0034] Referring to Figure 3 and 4 , this is the third embodiment of the present utility model, and this embodiment is based on the previous two embodiments.

[0035] In this embodiment, a sliding groove 6 is formed at the bottom of the connecting block 509. A sliding block 7 is fixedly connected to the bottom of the inner cavity of the auxiliary groove 508. The top of the sliding block 7 extends into the inner cavity of the sliding groove 6 and is slidably connected to the inner cavity of the sliding groove 6.

[0036] A limiting post 9 is fixedly connected to the inner cavity of the sliding groove 6. The limiting post 9 is slidably connected to the inner cavity of the sliding block 7. A second spring 8 is sleeved on the surface of the limiting post 9. The front end of the second spring 8 is fixedly connected to the inner wall of the sliding groove 6, and the rear end of the second spring 8 is fixedly connected to the sliding block 7.

[0037] As Figure 3 and 4 shown, while the connecting block 509 moves, it will cooperate with the sliding block 7 to squeeze the second spring 8. The reset elastic force of the sliding block 7 can reset the movable plate 507 and the connecting block 509, and the limiting post 9 can limit the connecting block 509.

[0038] When in use, when the housing body 2 needs to be installed, first push the movable plate 507 backward. When the movable plate 507 moves, it can make the connecting block 509 cooperate with the connecting rope 504 and the guide wheel 512 to pull the positioning block 503, so that it moves upward inside the receiving groove 502. During the movement of the positioning block 503, the first spring 505 will deform due to the pressure. While the connecting block 509 moves, it will cooperate with the sliding block 7 to squeeze the second spring 8 and make it deform. Then move the housing body 2, insert the mounting plate 4 into the inner part of the limiting frame 3. After the insertion is completed, release the movable plate 507. At this time, the pressure on the first spring 505 and the second spring 8 disappears and they reset. The reset elastic forces of the two respectively drive the positioning block 503 and the connecting block 509 to reset, so that the positioning block 503 can enter the positioning hole 501 and be engaged with it, thereby achieving the purpose of installing the housing body 2.
