[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] The present invention provides a valve straight-through connector that is convenient for quick connection. Figure 1-Figure 5 As shown, it includes a pipe 1 and a straight joint 3; a straight joint 3 is installed on one side of the pipe 1, a stop block 5 is fixed on the outside of one end of the pipe 1, and a connecting structure 2 is provided at the connection between the pipe 1 and the straight joint 3; a dustproof structure 4 is provided on the outside of the connection between the pipe 1 and the straight joint 3.

[0027] In a further preferred embodiment of the present invention, Figure 1-Figure 5As shown: the connection structure 2 includes an extrusion block 201, an extrusion ring 202, an extrusion groove 203, a threaded sleeve 204, a sealing ring 205 and a sealing groove 206. The extrusion groove 203 is opened inside one end of the straight-through joint 3, and the extrusion ring 202 is installed inside the extrusion groove 203. The extrusion block 201 is arranged at one end of the pipeline 1, and the threaded sleeve 204 is installed on the outside of one end of the straight-through joint 3. A sealing groove 206 is opened inside one end of the threaded sleeve 204, and a sealing ring 205 is installed inside the sealing groove 206. One end of the extrusion block 201 squeezes the extrusion ring 202 into the interior of the extrusion groove 203, and a sealed connection is formed between the extrusion block 201 and the extrusion ring 202. The extrusion ring 202 and the sealing ring 205 are made of rubber. The inner side of the threaded sleeve 204 is provided with an internal thread, and the outer side of one end of the pipeline 1 is provided with an external thread. A threaded connection is formed between the threaded sleeve 204 and the pipeline 1, and the threaded connection makes it more convenient during installation.

[0028] Specifically, in this embodiment: when connecting the valve and the pipeline 1, one end of the straight joint 3 is threadedly connected to one end of the valve. After the connection is completed, the extrusion ring 202 is installed into the inside of the extrusion groove 203, and the sealing ring 205 is installed into the inside of the sealing ring 205. After the installation is completed, the pipeline 1 and the straight joint 3 are aligned. After the alignment is completed, the extrusion block 201 is inserted into the inside of the extrusion groove 203. After the insertion is completed, the threaded sleeve 204 is rotated. As the threaded sleeve 204 rotates, the threaded sleeve 204 moves at one end outside the straight joint 3. Since the outer side of one end of the pipeline 1 is provided with an external thread, as one end of the threaded sleeve 204 is threadedly connected to one end of the pipeline 1, the pipeline 1 and the straight joint 3 are connected, making it more convenient to install and connect the pipeline 1 and the straight joint 3.

[0029] When the pipe 1 and the straight connector 3 are connected, one end of the threaded sleeve 204 just rests against one side of the block 5. When the pipe 1 and the straight connector 3 are connected, the extrusion block 201 will squeeze the extrusion ring 202 to complete the initial sealing, and when one end of the threaded sleeve 204 rests against one side of the block 5, one end of the threaded sleeve 204 will drive the sealing ring 205 to rest against one side of the block 5 to complete the re-sealing. Therefore, after the pipe 1 and the straight connector 3 are connected, the connection is not prone to water leakage, thereby completing the sealing work.

[0030] In a further preferred embodiment of the present invention, Figure 1-Figure 5As shown: the dustproof structure 4 includes a hoop 401, a bolt 402, a nut 403, a dustproof ring 404 and a dustproof groove 405. The dustproof groove 405 is opened at one end of the threaded sleeve 204 and the outside of the block 5. The hoop 401 is sleeved on the outside of one end of the threaded sleeve 204. A dustproof ring 404 is fixed inside the hoop 401. A bolt 402 is inserted into the top of the hoop 401. A nut 403 is provided at one end of the bolt 402. The nut 403 is installed on the outside of one end of the bolt 402. A threaded connection is formed between the nut 403 and the bolt 402. Two groups of dustproof rings 404 are provided, and the two groups of dustproof rings 404 are symmetrically distributed inside the hoop 401.

[0031] Specifically, in this embodiment, when the threaded sleeve 204 completes the connection between the pipe 1 and the straight connector 3, the clamp 401 is sleeved on the outside of the threaded sleeve 204 and the block 5. After the sleeve is installed, the bolt 402 is inserted into the inside of the top of the clamp 401. After the insertion is completed, the nut 403 is installed on the outside of the bolt 402. After the installation is completed, as the nut 403 rotates on the bolt 402, the clamp 401 is fixed. When the clamp 401 is fixed, the dust ring 404 is squeezed into the inside of the dustproof groove 405 to perform a dust-proof work, so that after the pipe 1 and the straight connector 3 are connected, there will be no dust accumulation at the connection to affect the connection effect, thereby completing the dust-proof work.

[0032] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
