Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-4As shown, a filter-type floating blind-mating fluid connector plug includes a socket body 1, a connecting component 2 disposed on the inner wall of the socket body 1, and a filter component 3 disposed at one end of the socket body 1; the connecting component 2 includes a plug body 201, and a first sealing groove 202 is formed on the inner wall of the plug body 201, a first sealing ring 203 is disposed on the inner wall of the first sealing groove 202, a threaded head 204 is threadedly connected to the inner wall of the socket body 1, and a second sealing groove 205 is formed on the inner wall of the threaded head 204, a second sealing ring 206 is disposed on the inner wall of the second sealing groove 205; the filter component 3 includes... The device includes a housing 301, with a cover 302 detachably connected to the top of the housing 301. The outer wall of the cover 302 is provided with fixing bolts 303, and the inner wall of the cover 302 is provided with a third sealing groove 304. The inner wall of the third sealing groove 304 is provided with a third sealing ring 305. A filter screen 306 is fixedly connected to the bottom of the cover 302. A drain port 307 is fixedly connected to the bottom of the housing 301, and a threaded cap 308 is threadedly connected to the outer wall of the drain port 307. A sealing gasket 309 is provided on the inner wall of the threaded cap 308. A connecting pipe 310 is fixedly connected to one side of the housing 301.

[0025] With the above technical solution, when it is necessary to clean or replace the filter screen 306, it is only necessary to remove the fixing bolt 303 to separate the cover 302 from the mounting shell 301 and directly remove the filter screen 306 without disassembling the entire connector. The disassembly steps are few, the operation is simple, and it is easy to use. By removing the threaded cover 308 on the drain port 307, it is convenient to periodically discharge the deposited impurities without removing the filter screen 306. The plug body 201 and the socket body 1 form a primary seal through the first sealing ring 203, and the threaded connection between the threaded head 204 and the socket body 1, in conjunction with the second sealing ring 206, forms a secondary seal. The double seal enhances the sealing performance and effectively prevents fluid leakage. The mounting shell 301 is fixedly connected to one side of the socket body 1.

[0026] Specifically, one end of the plug body 201 extends into the socket body 1, and the outer wall of the plug body 201 fits against the inner wall of the socket body 1.

[0027] The above technical solution facilitates the floating blind insertion of the plug body 201 into the socket body 1, and the outer wall of the plug body 201 fits against the inner wall of the socket body 1, enhancing the sealing performance; the inner cavity of the socket body 1 matches the inner cavity of the plug body 201, facilitating fluid passage; the threaded head 204 slides on the plug body 201, facilitating connection, and the flange on the plug body 201 prevents the threaded head 204 from falling off, facilitating use during floating blind insertion.

[0028] Specifically, the inner wall shape and size of the first sealing groove 202 match the outer wall shape and size of the first sealing ring 203, and the inner wall of the first sealing groove 202 fits against the outer wall of the first sealing ring 203.

[0029] The above technical solution enhances the connection between the first sealing groove 202 and the first sealing ring 203. By providing the first sealing ring 203, the sealing performance at the connection between the socket body 1 and the plug body 201 is improved.

[0030] Specifically, the inner wall shape and size of the second sealing groove 205 match the outer wall shape and size of the second sealing ring 206, and the inner wall of the second sealing groove 205 fits against the outer wall of the second sealing ring 206.

[0031] The above technical solution enhances the connection between the second sealing groove 205 and the second sealing ring 206. When the threaded head 204 presses the plug body 201 against the socket body 1, the outer wall of the second sealing ring 206 fits against the plug body 201, thus enhancing the sealing performance.

[0032] Specifically, the mounting shell 301 is fixed to the shell cover 302 by fixing bolts 303, and one end of the fixing bolts 303 is threaded through the shell cover 302 and extends into the mounting shell 301 for connection.

[0033] With the above technical solution, there are multiple fixing bolts 303, which can effectively fix the cover 302 to the mounting shell 301, making it easy to install and disassemble.

[0034] Specifically, one end of the cover 302 extends into the mounting shell 301, and the outer wall of the cover 302 fits against the inner wall of the mounting shell 301.

[0035] Through the above technical solution, the outer wall of the cover 302 fits against the inner wall of the mounting shell 301, which enhances the sealing performance. The cover 302 is inserted into the mounting shell 301 for installation. The outer wall of the third sealing ring 305 on the cover 302 fits against the inner wall of the mounting shell 301, which enhances the sealing performance at the connection between the cover 302 and the mounting shell 301.

[0036] Specifically, the inner wall shape and size of the mounting shell 301 match the outer wall shape and size of the filter screen 306, and the inner wall of the mounting shell 301 fits snugly against the outer wall of the filter screen 306.

[0037] The above technical solution enhances the connection between the mounting housing 301 and the filter screen 306, making it easier for the filter screen 306 to be inserted into the mounting housing 301 for installation. The filter screen 306 can effectively intercept impurities in the fluid.

[0038] In use, when performing a blind insertion operation, one end of the plug body 201 is inserted into the inner cavity of the socket body 1. Initial positioning is achieved by the contact between the outer wall of the plug body 201 and the inner wall of the socket body 1. By rotating the threaded head 204, it is pushed along the internal thread of the socket body 1 until the threaded head 204 completely presses the plug body 201 against the socket body 1. At this time, the first sealing ring 203 is in contact with the inner wall of the socket body 1, enhancing the sealing performance. The second sealing ring 206 on the threaded head 204 is in contact with the plug body 201, forming a secondary seal. The double seal ensures no fluid leakage. The fluid enters the inner cavity of the mounting shell 301 from the connecting pipe 310, first passing through the filter screen 306, which is made of 400-mesh stainless steel sintered mesh. The filtered clean fluid enters the fluid passage of the plug body 201 through the flow channel of the socket body 1. When it is necessary to clean the deposited impurities, shut off the fluid system, remove the threaded cap 308 on the drain port 307, and the impurities will be discharged under gravity. When installing the threaded cap 308, place the sealing gasket 309 inside the threaded cap 308 and thread the threaded cap 308 onto the drain port 307. The sealing performance is enhanced by the sealing gasket 309. When the filter screen 306 needs to be thoroughly cleaned or replaced, remove the fixing bolts 303 and pull the cover 302 upwards by the handle to remove the filter screen 306, which is convenient for cleaning or replacing the filter screen 306. During installation, insert the cover 302 into the mounting shell 301 and fix the cover 302 to the mounting shell 301 using the fixing bolts 303 to complete the installation. This completes all the work. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
