Detailed Description
The invention will be described in further detail with reference to the following detailed description and accompanying drawings: referring to fig. 1 to 4, the oil pipe sealing head comprises a sealing pipe 1, wherein a flange part 10 is arranged at one end of the sealing pipe 1;
further comprising a mounting seat 2, said mounting seat 2 cooperating with said flange portion 10 such that it is fixed at the one end of said sealing tube 1.
A cover member 3 is rotatably provided on the mount 2; a sealing element 4 is sleeved outside the sealing tube 1, one end of the sealing element 4 is pressed and limited between the mounting seat 2 and the sealing tube 1, the other end of the sealing element 4 forms a sealing lip 40 which is inwardly contracted, and the cover component 3 is elastically biased by a torsion spring 5 so that sealing is formed between the sealing lip 40 and the end surface of the cover component 3.
In the structure, the oil pipe sealing joint is simple and convenient to assemble, only three parts of the mounting seat 2, the sealing element 4 and the cover component 3 need to be installed, in addition, the sealing element is compressed between the mounting seat 2 and the sealing pipe 1 and is sealed through the extended sealing lip 40, and the sealing performance of the sealing element 4 to the cover component is greatly improved.
Specifically, the cover member 3 and the mounting seat 2 are rotatably supported through a rotating shaft 100, the torsion spring 5 is sleeved outside the rotating shaft 100, one end of the torsion spring 5 abuts against the middle of the cover member 3, and the other end of the torsion spring 5 abuts against the side wall of the mounting seat. A limiting groove 30 is formed in the middle of the cover member 3, and one end of the torsion spring 5 is located in the limiting groove 30.
Preferably, one end of the sealing element 4 is provided with a stop ring 41, a stop groove 11 is provided on the side wall of the mounting seat 2, and the stop ring 41 is located in the stop groove 11, so as to further prevent the axial displacement of the sealing element 4 and prevent it from falling out; furthermore, an annular support portion 12 is convexly disposed on the lower end surface of the sealing tube 1, and the support portion 12 abuts against the sealing lip 40. By the support portion 12 abutting against the seal lip 40, support can be further provided to the seal lip 40, and deformation of the seal lip 40 during use is prevented, so that the sealing effect is further improved.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The foregoing embodiments and description of the invention have been provided in the present application for the purpose of illustrating the principles of the invention and is subject to various changes and modifications without departing from the spirit and scope of the invention. All such variations and modifications are intended to be within the scope of the claimed invention.
