[0027] The present utility model provides a snap-on plastic shell as Figure 1 shown, including a plastic shell body 1, and further including:

[0028] A sealing mechanism 2, which is arranged on the top of the plastic shell body 1 and is used for sealing the top of the plastic shell body 1.

[0029] In order to enable the plastic shell body 1 to be conveniently connected to the sealing mechanism 2, as Figure 1-2 and Figure 4 shown, the plastic shell body 1 includes a fixed shell 101. Both ends of the outer walls on both sides of the fixed shell 101 are provided with connecting grooves 103, and both ends of the inner walls of the fixed shell 101 are provided with fixed grooves 105. Through the connection between the connecting grooves 103 and the fixed grooves 105 and the sealing mechanism 2, the sealing mechanism 2 can stably seal the top of the plastic shell body 1.

[0030] In order to enable the sealing mechanism 2 to stably seal the fixed shell 101, as Figure 1-5As shown in the figure, the sealing mechanism 2 includes a cover plate 201. At both ends of the two sides of the bottom of the cover plate 201, clamping plates 202 are rotatably installed. The four clamping plates 202 are respectively movably connected with the four connecting grooves 103. At both ends of the inner top wall of the cover plate 201, adjusting screws 205 are provided. Threaded sleeves of the outer walls of the two adjusting screws 205 are respectively connected with connecting plates 206. The two connecting plates 206 are respectively movably connected with the inner walls of the two fixing grooves 105. The connection between the clamping plate 202 and the connecting groove 103 and the connection between the connecting plate 206 and the fixing groove 105 enable the cover plate 201 to be stably connected to the fixed housing 101.

[0031] To make the fixed housing 101 and the cover plate 201 closely connected, as Figure 2-4 shown, a convex block 102 is fixedly installed on the top of the fixed housing 101. The outer wall of the convex block 102 is movably connected with the inner wall of the cover plate 201. The area size of the top view cross-section of the inner wall of the fixed housing 101 is the same as the area size of the top view cross-section of the inner wall of the convex block 102. The connection between the convex block 102 and the cover plate 201 enables the cover plate 201 to stably seal the top of the fixed housing 101.

[0032] To make the connecting groove 103 and the clamping plate 202 closely connected, as Figure 2 and Figure 4-5 shown, plug-in plates 104 are fixedly installed on the inner walls of the four connecting grooves 103. Clamping grooves 203 are provided on the inner walls of the four clamping plates 202. The outer wall of the plug-in plate 104 is movably connected with the inner wall of the adjacent clamping groove 203. The front view vertical cross-sections of the plug-in plate 104 and the clamping groove 203 are both rectangular structures. The left view vertical cross-sections of the connecting groove 103 and the clamping plate 202 are both L-shaped structures. The connection between the plug-in plate 104 and the clamping groove 203 enables the clamping plate 202 to be closely connected to the connecting groove 103.

[0033] To conveniently adjust the connecting plate 206, as Figure 2-3 and Figure 5 shown, the sealing mechanism 2 includes movable grooves 204. There are two movable grooves 204, which are respectively opened at both ends of the inner top wall of the cover plate 201. The inner walls of the two movable grooves 204 are respectively rotatably connected with the two adjusting screws 205. The inner walls of the two movable grooves 204 are respectively movably connected with the top outer walls of the two connecting plates 206. The bottom surface of the fixing groove 105 is at the same height as the inner bottom surface of the fixed housing 101. The front view vertical cross-section of the connecting plate 206 is an L-shaped structure. The movable groove 204 can limit the movement of the connecting plate 206, enabling the connecting plate 206 to be stably adjusted, and further conveniently adjusting the connection state between the connecting plate 206 and the fixing groove 105.

[0034] When the device is in use, the cover plate 201 is sleeved onto the outer side of the protrusion 102 on the top of the fixed shell 101, so that the bottom of the cover plate 201 is used to fix the clamping plate 202 to the top of the inner wall of the four connecting grooves 103, and then the four clamping plates 202 are rotated from the horizontal state to the vertical downward state so that they can be tightly connected with the inner wall of the connecting groove 103, and at the same time, the plug-in plate 104 on the inner wall of the connecting groove 103 can be plugged into the clamping groove 203 on the inner wall of the adjacent clamping plate 202, and at the same time, the two connecting plates 206 can be moved along the inner wall of the adjacent movable groove 204 on the outside thereof by rotating the two adjusting screws 205. The cover plate 201 is connected to the fixed housing 101 by the fixing groove 105, and the fixing groove 105 is connected to the fixing groove 105. The fixing groove 105 is connected to the fixing plate 206, and the fixing groove 105 is connected to the fixing plate 206 ...

[0035] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
