The fixing strength of the box body 3 is relatively high, and the box body 3 is not easily loosened.

[0037] As a possible implementation manner, the base 1 is provided with a mounting hole 52 communicating the groove 11 and the side wall of the base 1. The mounting hole 52 is provided with a connecting rod 54, and the connecting rod 54 is connected to the insertion plate 53. The connecting rod 54 can drive the insertion plate 53 to move relative to the groove 11. Specifically, a connecting groove 51 is provided in the base 1, and the mounting hole 52 is connected to the groove 11 through the connecting groove 51. At least part of the insertion plate 53 is accommodated in the connecting groove 51.

[0038] During actual implementation, the mounting hole 52 can be a threaded hole, and the connecting rod 54 can be a screw rod. When the connecting rod 54 rotates relative to the mounting hole 52, it drives the insertion plate 53 to linearly move relative to the groove 11 for insertion into the slot 24.

The stop block 61 is used to abut against the connecting plate 22 when the limiting protrusion 23 is connected in the groove 11 to limit the connecting plate 22 from moving away from the base 1.

[0040] In specific implementation, the stop block 61 includes a first part and a second part. The first part is used for sliding connection with the base 1; the second part is fixedly connected to one end of the first part away from the base 1, and the projected area of the second part on the base 1 is larger than the projected area of the first part on the base 1, that is, the cross-sectional shape of the stop block 61 can be L-shaped. The second part is used to abut against the connecting plate 22 when the limiting protrusion 23 is connected in the groove 11. The stop block 61 can further limit the connecting piece 2 and improve the installation stability of the box body 3.

A limiting slider 62 is provided in the limiting chute 63, and the limiting slider 62 can slide in the limiting chute 63; the stop block 61 is connected to the limiting slider 62 to be able to slide relative to the base 1.

[0042] In a specific implementation, in a direction parallel to the base 1, the cross-sectional area of ​​the end of the limiting slide 63 away from the box body 3 is larger than the cross-sectional area of ​​the end of the limiting slide 63 close to the box body 3. For example, the cross-sectional shape of the limiting slide 63 in a direction perpendicular to the base 1 can be a trapezoid. In this case, the limiting slide 63 can be called a dovetail slide. The cross-sectional area of ​​the end of the limiting slider 62 away from the box body 3 is larger than the cross-sectional area of ​​the end of the limiting slider 62 close to the box body 3. For example, the cross-sectional shape of the limiting slider 62 in a direction perpendicular to the base 1 can also be a trapezoid. In this case, the limiting slider 62 can be called a dovetail slider. In addition, the cross-sectional area of ​​the end of the limiting slider 62 away from the box body 3 is larger than the cross-sectional area of ​​the end of the limiting slide 63 close to the box body 3, so that the limiting slider 62 is limited in the limiting slide 63.

[0043] During specific implementation, an elastic member 64 is provided in the limiting slide groove 63 , one end of the elastic member 64 is connected to the inner wall of the limiting slide groove 63 , and the other end of the elastic member 64 is connected to the limiting slider 62 , and the elastic member 64 is used to drive the limiting slider 62 to slide in the limiting slide groove 63 .

[0044] As a possible implementation, the base 1 is provided with a mounting through hole, in which a fan 42 is provided, and the fan 42 is used to dissipate heat from the box body 3. A sealing ring 44 is provided at one end of the mounting through hole facing the box body 3, and the sealing ring 44 is used to abut against the box body 3. The sealing ring 44 is an annular structure, and can be made of rubber material, and fits with the lower surface of the box body 3 to play a sealing role, so that the fan 42 can draw the outside air into the box body 3, and then discharge it through the air outlet on the box body 3, thereby improving the heat dissipation effect of the fan 42. A mounting convex plate 41 is provided at one end of the mounting through hole away from the box body 3, and the mounting convex plate 41 has a gas through hole, and the gas through hole at least partially overlaps with the mounting through hole in the direction perpendicular to the base 1. The mounting convex plate 41 is provided with a filter screen plate 43, and the projection of the filter screen plate 43 on the base 1 covers the mounting through hole. The filter screen plate 43 can play a role of sealing and filtering, thereby filtering dust and impurities in the air, and also improving the heat dissipation effect of the fan 42.

[0045] In specific implementation, the mounting convex plate 41 can be made of a magnetic material, and the filter screen plate 43 can be made of a metal material. The filter screen plate 43 is magnetically connected to the mounting convex plate 41 to cover the mounting through hole, and the filter screen plate 43 is easy to disassemble and clean. There can be multiple mounting convex plates 41, for example, there are four mounting convex plates 41, each mounting convex plate 41 is arc-shaped, and multiple mounting convex plates 41 are arranged around the mounting through hole on the side of the base 1 away from the box body 3, and there is a gap between adjacent mounting convex plates 41; the bracket 45 of the fan 42 can be fixedly connected to the gap between two adjacent mounting convex plates 41 by bolts. Alternatively, the bracket 45 of the fan 42 can be fixedly connected to the hole wall of the mounting through hole to be fixedly connected in the mounting through hole.

[0046] As a possible implementation, there may be two connecting plates 22, and the two connecting plates 22 are arranged in parallel; there may be two connecting beams 21, and the two connecting beams 21 are arranged in parallel. Each connecting beam 21 is respectively connected to the two connecting plates 22, and the two connecting plates 22 and the two connecting beams 21 are connected to form a frame structure. The limiting protrusions 23 on the two connecting beams 21 are arranged in parallel. Correspondingly, there may be two grooves 11, and the two grooves 11 are arranged in parallel. The distance between the two grooves 11 is equal to the distance between the two limiting protrusions 23. There may also be two stoppers 61, and the two stoppers 61 are respectively located in the middle of both ends of the upper surface of the base 1, so that each stopper 61 corresponds to the middle of one connecting plate 22.

[0047] In the embodiment of the present application, when the connecting member 2 is installed on the base 1, first place the limiting protrusion 23 in the groove 11 to realize the limitation of the connecting member 2 in the left-right direction. Before that, move the stopper 61 first so that the stopper 61 does not prevent the limiting protrusion 23 from falling into the groove 11. When the limiting protrusion 23 is located in the groove 11, release the stopper 61. At this time, the stopper 61 is reset under the action of the elastic member 64 to limit the connecting plate 22, realizing the limitation of the connecting member 2 in the up-down and front-back directions. Then turn the connecting rod 54, and the connecting rod 54 cooperates with the mounting hole 52 to drive the plug plate 53 to move until the plug plate 53 is inserted into the slot 24 on the limiting protrusion 23 to limit the limiting protrusion 23, further realizing the limitation of the connecting member 2 in the up-down and front-back directions. At this time, the connecting member 2 is stably installed on the base 1, thereby improving the installation stability of the box body 3. When the box body 3 is installed, the sealing ring 44 on the base 1 fits with the lower surface of the box body 3, playing a role of sealing and guiding air, so that the fan 42 can draw the outside air into the box body 3, improving the heat dissipation effect.
