[0025] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0026] like Figure 1 to Figure 2 As shown, a detachable sealing device includes a base assembly weldment 1, an upper cover assembly weldment 2, and a plug-in box assembly weldment 3. The upper cover assembly weldment 2 is installed on the top of the base assembly weldment 1, and the plug-in box assembly weldment 3 is installed inside the base assembly weldment 1. The base assembly weldment 1 includes a base body 11, a base fixing seat 12, a base upper sealing rubber pad 13 and a base lower sealing rubber pad 14. The base body 11 is a hollow rectangular parallelepiped structure, and the plug-in box assembly weldment 3 is installed inside the base body 11. Two base fixing seats 12 are respectively installed on both sides of the bottom of the base body 11. The bottom of the base body 11 is installed to the base lower sealing rubber pad 14 through the base fixing seat 12, and the top of the base body 11 is installed to the upper cover assembly weldment 2 through the base fixing seat 12. The base upper sealing rubber pad 13 is also installed between the base body 11 and the upper cover assembly weldment 2.

[0027] In a preferred embodiment of the present invention, the upper and lower ends of one side of the base body 11 are respectively provided with a base upper limit hole 111 and a base lower limit hole 112, and the base upper limit hole 111 and the base lower limit hole 112 are used for detachable connection with the plug-in box assembly weldment 3.

[0028] In a preferred embodiment of the utility model, the sealing device has the advantage of being detachable: the plug-in box assembly weldment 3 can be removed from the base assembly weldment 1; it can also be fixed in the grooves of the upper limit hole 111 and the lower limit hole 112 of the base by the upper limit member 3231 and the lower limit member 3232.

[0029] In a preferred embodiment of the utility model, the upper cover assembly weldment 2 includes an upper cover body 21 and an upper cover fixing seat 22. Two upper cover fixing seats 22 are respectively installed on both sides of the bottom of the upper cover body 21. The upper cover body 21 is installed above the base body 11 through the upper cover fixing seats 22.

[0030] In a preferred embodiment of the present invention, the plug-in box weldment 3 includes a plug-in box body 31, a spring assembly 32 and a back cover assembly 33. The plug-in box body 31 is installed inside the base body 11, the spring assembly 32 is installed at one end of the plug-in box body 31, and the back cover assembly 33 is installed on one side of the spring assembly 32.

[0031] In a preferred embodiment of the utility model, the sealing device has the advantage of changing the installation point from inside to outside: the installation point of the base fixing seat 12 is previously inside the base body 11, which has the disadvantages of being difficult to install and poorly sealed after opening. Now it is improved to be installed outside the base body 11.

[0032] In a preferred embodiment of the utility model, the spring assembly 32 includes a mounting plate 321, a spring correcting plate 322, a rotating mechanism 323, a spring body 324, a spring fixing screw 325, and a limit screw 326.

[0033] In a preferred embodiment of the utility model, the sealing device has the advantages of tension spring over magnetic control: the rotating mechanism 323 is fixed by magnetism before, which has the disadvantage of demagnetization. When the maximum working temperature is exceeded, the magnetic material will demagnetize, resulting in irreversible loss, small magnetic force and poor effect. Now it is improved to a spring mechanism.

[0034] The upper and lower ends of the rotating mechanism 323 are respectively provided with an upper limit piece 3231 and a lower limit piece 3232. The upper limit piece 3231 is used in conjunction with the upper limit hole 111 of the base, and the lower limit piece 3232 is used in conjunction with the lower limit hole 112 of the base. In actual use, the upper limit hole 111 of the base and the lower limit hole 112 of the base are respectively detachably arranged with the upper limit piece 3231 and the lower limit piece 3232.

[0035] In a preferred embodiment of the utility model, the sealing device has the advantage of fixed point positioning: the upper limit member 3231 and the lower limit member 3232 are clamped in the grooves of the upper limit hole 111 and the lower limit hole 112 of the base to fix the plug-in box assembly; the two-point fixation is firmer, more balanced, and more evenly stressed than the one-point fixation.

[0036] In a preferred embodiment of the utility model, the rear cover assembly 33 includes a rear cover sealing gasket 331, a rear cover plate body 332, a rear cover sealing sleeve 333, and a rear cover fixing screw 334. The rear cover plate body 332 is installed to one side of the mounting plate 321 by four rear cover fixing screws 334, and a rear cover sealing gasket 331 is also installed between the rear cover plate body 332 and the mounting plate 321, and a rear cover sealing sleeve 333 is installed in the middle of the rear cover plate body 332.

[0037] In a preferred embodiment of the utility model, the sealing device has a sealing advantage and a protection level of IP67: glue is poured inside the base assembly weldment 1 to protect the circuit board seal; the upper limit hole 111 of the base is sealed with the upper sealing rubber pad 13 of the base; the lower limit hole 112 of the base is sealed with the lower sealing rubber pad 14 of the base; one side of the base assembly weldment 1 is finally sealed with the back cover rubber pad 331; the rotating mechanism 323 is sealed with the back cover sealing sleeve 333.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
