Abstract
The utility model is suitable for an interior sleeve pipe technical field. The utility model discloses an inner sleeve of a PTFE non-standard thread, which comprises a sleeve main body (1), wherein the sleeve main body (1) is tubular, a thread (11) is arranged outside the sleeve main body, and an inverted trapezoidal groove (111) is arranged in the middle of the thread (11); the beneficial effects of the utility model reside in that: the distance between the threads is wider than that of the standard threads, and the threads are provided with inverted trapezoidal grooves, so that the meshing force between the threads is increased; the material is polytetrafluoroethylene, and has strong corrosion resistance and toughness.
Description
Technical Field
The utility model relates to an interior sleeve pipe technical field, in particular to interior sleeve pipe of nonstandard screw thread of PTFE.
Background
In the existing life, the inner sleeve is taken as a component and is widely applied to the fields of equipment such as machinery, chemical engineering, aviation, electrical and electronic, national defense industry, advanced science and technology, medical sanitation, electrical insulation and the like.
At present, all inner sleeves used are standard threaded inner sleeves, and are made of silica gel or other common plastics; the novel screw is arranged on mechanical equipment, the meshing force between standard threads is general, the novel screw is often loosened and fallen off, the corrosion resistance and the toughness of the novel screw are poor, and the novel screw is easy to damage.
SUMMERY OF THE UTILITY MODEL
The utility model mainly solves the technical problem of providing an inner sleeve of PTFE non-standard thread, which is not easy to fall off and loose when being arranged on mechanical equipment; and has strong corrosion resistance and toughness.
In order to solve the problems, the utility model provides an inner sleeve of a PTFE non-standard thread, which comprises a sleeve main body, wherein the sleeve main body is tubular, the outer part of the sleeve main body is provided with a thread, and the middle of the thread is provided with an inverted trapezoidal groove; the pitch of the threads is wider than a standard thread pitch; the sleeve main body is used for being installed on mechanical equipment; the sleeve main body is made of polytetrafluoroethylene.
Furthermore, when the sleeve main body is arranged on mechanical equipment, the space between the threads is wider than the space between the standard threads, so that the meshing force between the threads is increased, and the toughness of the threads is enhanced due to the inverted trapezoidal grooves of the threads; finally, the sleeve body is tightly combined with the mechanical equipment.
Furthermore, the sleeve main body is made of polytetrafluoroethylene, and has strong corrosion resistance and toughness.
When the sleeve is used, when the sleeve main body is arranged on mechanical equipment, the space between the threads is wider than the standard thread space, so that the meshing force between the threads is increased, and the toughness of the threads is enhanced due to the inverted trapezoidal grooves of the threads; finally, the sleeve body is tightly combined with the mechanical equipment.
The beneficial effects of the utility model reside in that: the distance between the threads is wider than that of the standard threads, and the threads are provided with inverted trapezoidal grooves, so that the meshing force between the threads is increased; the material is polytetrafluoroethylene, and has strong corrosion resistance and toughness.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, and it is obvious that the drawings in the description are some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to the drawings without creative efforts.
Fig. 1 is a schematic cross-sectional view of the present invention.
Fig. 2 is a front view schematically illustrating the present invention.
The objects, features and advantages of the present invention will be further explained with reference to the accompanying drawings.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some embodiments, not all embodiments, of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1 and 2, the PTFE non-standard threaded inner sleeve comprises a sleeve main body 1, wherein the sleeve main body 1 is tubular, a thread 11 is arranged outside the sleeve main body 1, and an inverted trapezoidal groove 111 is arranged in the middle of the thread 11; the pitch of the threads 11 is wider than the standard thread pitch; the sleeve main body 1 is used for being mounted on mechanical equipment; the sleeve main body 1 is made of polytetrafluoroethylene.
Specifically speaking: when the sleeve main body 1 is used for being installed on mechanical equipment, the space between the threads 11 is wider than the standard thread space, so that the meshing force between the threads is increased, and the toughness of the threads 11 is enhanced due to the inverted trapezoidal grooves 111 of the threads 11; finally, the sleeve body 1 is tightly combined with the mechanical equipment.
Referring to fig. 1 and 2, when the sleeve body 1 is used for being mounted on mechanical equipment, because the distance between the threads 11 is wider than the standard thread distance, the engagement force between the threads is increased, and the inverted trapezoidal grooves 111 of the threads 11 enhance the toughness of the threads 11; finally, the sleeve body 1 is tightly combined with the mechanical equipment.
Referring to fig. 1 and 2, the sleeve body 1 is made of polytetrafluoroethylene, and has high corrosion resistance and toughness.
The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: it is to be understood that modifications may be made to the above-described arrangements in the embodiments or equivalents may be substituted for some of the features of the embodiments without departing from the spirit or scope of the present invention.
