[0003] However, similar solutions mentioned above use iron wire to wrap around both ends of the pipe for fixing, and pliers are needed to tie it during the fixing process. After long-term use, the binding becomes loose and needs to be fixed with a carrying workpiece, which causes inconvenience. In addition, excessive force during the binding process may damage the fixing protrusions at the connection, resulting in a poor seal.

DETAILED DESCRIPTION

[0020] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0021] like Figures 1 to 4As shown, a sealing pipe fitting for connecting a main engine to a wheel sensor conduit comprises a corrugated tube 1, a connecting assembly 4 and a clamping assembly 6. Both ends of the corrugated tube 1 are fixedly connected with connecting tubes 2, which can be stretched and compressed to adapt to the length of the sensor wire. The material of the connecting tube 2 is relatively hard and can support the connection to avoid damage to the sensor wire when tightening. The end of the connecting tube 2 away from the corrugated tube 1 is slidably connected with a connecting block 3. The inner right end of the connecting block 3 is fixed with an internal thread 31 for passing through the connecting tube 2 and fixing it with the connecting seat 401. The connecting assembly 4 is located on the corrugated tube 1. The right end of the connecting block 3 is provided with a connecting column 402, and the connecting assembly 4 includes a connecting seat 401, a connecting column 402, a supporting rod 403, a reset spring 404 and a clamping block 405. The right end of the connecting block 3 is threadedly connected with the connecting column 402, and the outer side of the connecting column 402 is fixed with an outer thread 423 adapted to the inner thread 31, so that the connecting block 3 is tightened on the outer side of the connecting column 402 to fix the connecting pipe 2 and the connecting assembly 4, and the connecting block 3 is connected with the connecting seat 401 by thread to form a disassembly structure, and the pipe fitting is conveniently connected to the connecting assembly 4 by threaded connection, so as to facilitate installation;

[0022] A fastening plate 421 is fixed to one side of the connecting column 402 close to the connecting block 3. Since the left diameter of the connecting block 3 is smaller than the right diameter of the connecting block 3, the fastening plate 421 is tightened inward as the connecting block 3 is screwed in, so that the fastening plate 421 is tightly connected to the connecting pipe 2, thereby improving the tightness of the connection. A rubber pad 422 is bonded to the inner side of the fastening plate 421 to further increase the friction between the connecting pipe 2 and the fastening plate 421 to prevent the connection from becoming loose over time.

[0023] A connecting seat 401 is fixed to the right end of the connecting column 402, and a support rod 403 is provided on the inner side of the connecting seat 401, a return spring 404 is provided on the outer side of the support rod 403, and a clamping block 405 is fixed on the inner side of the support rod 403. The support rod 403, the return spring 404 and the clamping block 405 are symmetrically arranged in two groups about the vertical center line of the connecting seat 401 to improve the stability of the clamping part, and the support rod 403 forms a telescopic structure through the return spring 404 and the clamping block 405, and is fixed by inserting between the two groups of baffles of the clamping block 405, so that installation and disassembly can be achieved without using tools, thereby facilitating installation and disassembly, which is conducive to convenient maintenance for maintenance personnel;

[0024] The snap-fit ​​assembly 6 is located on the right side of the connecting assembly 4, and the snap-fit ​​assembly 6 includes a first baffle 601, a support tube 602 and a second baffle 603, and a support tube 602 is arranged on the inner side of the connecting seat 401, the left end of the support tube 602 is fixed with the first baffle 601, and the middle part of the outer side of the support tube 602 is slidably connected with the second baffle 603, and the second baffle 603 is used to assist the clamping block 405 to move to the left side of the first baffle 601, so that the connecting assembly 4 is separated from the snap-fit ​​assembly 6, and the right end of the support tube 602 is snap-fitted with a fixing protrusion 5, which is used to fix with a sealing pipe fitting on the sweeper, and the connecting assembly 4 forms a disassembly structure with the fixing protrusion 5 through the snap-fit ​​assembly 6, and the clamping block 405 slides to the right side of the first baffle 601 to fix the connecting assembly 4 with the fixing protrusion 5. In this process, it is possible to avoid squeezing the fixing protrusion 5 vigorously, prevent damage to the fixing protrusion 5, and avoid poor sealing.

[0025] In summary, when the sealing pipe fitting of the main engine to the wheel sensor conduit is used, first, the support tube 602 is sleeved on the outside of the fixing protrusion 5, and the connecting block 3 is sleeved on the outside of the connecting tube 2, so that the connecting column 402 is screwed with the internal thread 31 through the external thread 423, and during the tightening process, the connecting block 3 compresses the fastening plate 421 inwardly, so that the side of the fastening plate 421 with the rubber pad 422 is tightly fitted with the connecting tube 2, and the support tube 602 is inserted into the right side of the connecting seat 401, and the first baffle 601 slides along the oblique edge of the block 405 until it slides to the right side of the first baffle 601, and the block 405 is lifted by the return spring 404 and contacts the support tube 602, and the block 405 It is stuck between the first baffle plate 601 and the second baffle plate 603 to fix it. When disassembling, hold the connecting seat 401 and slide it to the right, so that the blocking block 405 slides over the second baffle plate 603 along the hypotenuse, and pushes the connecting seat 401 to move to the left. Since the second baffle plate 603 is a sliding connection, the blocking block 405 pushes the second baffle plate 603 to move to the left and fits with the right side of the first baffle plate 601. At this time, the first baffle plate 601 and the second baffle plate 603 are in a fixed state, so the connecting seat 401 is continued to be dragged to the left, so that the blocking block 405 is disengaged from the second baffle plate 603 and the first baffle plate 601 in turn, thereby separating the corrugated tube 1 from the fixing protrusion 5, and the other side is installed and disassembled in the same way.
