Description
Technical field
The invention belongs to electrification railway contact net part technical field, and in particular to a kind of run-resistant pipe cap.
Background technology
In parts of electrified railway contact network, pipe cap is mainly used in the closing of pipe part end.With the present invention most
Close prior art is " cantilever support device pipe cap（CN204020603U）" utility model patent.Using nylon injection-molding into
Type is manufactured, and is made up of body and bushing, bushing first is inserted into the mouth of pipe during installation, then installs body in bushing, passes through body pair
The effect of bushing realizes that bushing top edge is adjacent to pipe part inwall, and reduction pipe cap integrally comes off risk, but the pipe cap is difficult to
Installed using spanner class instrument, can only manual rotation body installed, cause install tightness it is low, make bushing top
The dynamics that edge is adjacent to pipe part inwall is small, only has bushing top edge to be adjacent to pipe part inwall after installation in addition,
Contact surface is small, or even the only linear contact lay of ring-type, therefore prevents that the reliability come off is not high.And during installation and removal
Easily there is body and bushing while the problem of rotating and can not control, the efficiency of loading and unloading is low.
The content of the invention
Present invention solves the technical problem that：A kind of run-resistant pipe cap is designed, the deficiency of prior art is overcome, not only loads and unloads
Efficiency high, and anticreep performance is good, it is ensured that the safety and stability of electrification railway contact net.
The technical solution of the present invention：A kind of run-resistant pipe cap, the pipe cap is by pipe cap main body and holds out against swivel nut and constitutes；
The outer wall lower end of the pipe cap main body is outward extended with outer circular edge, makes shape between the bottom outer wall of pipe cap main body and outer circular edge
Into an annular mounting groove, the outer wall top of pipe cap main body is in back taper, and is evenly distributed outside U-shaped breach, pipe cap main body
There is endless v groove in the middle part of wall, and make the bottom of endless v groove and the bottom insertion of U-shaped breach；The pipe cap main body
Endoporus bottom has internal thread, and the endoporus top of pipe cap main body has ring-type arc cam；Under the outer wall for holding out against swivel nut
Portion has external screw thread, and the outer wall top for holding out against swivel nut is in back taper, holds out against and interior hexagonal groove is formed with the lower surface of swivel nut；It is described
Swivel nut is held out against by external screw thread and the screw-internal thread fit spinning in the endoporus of pipe cap main body, and by holding out against on swivel nut outer wall
The ring-type arc cam that the back taper extruded tube cap main body endoporus top in portion has, makes the top of pipe cap main body along U-shaped breach
Separate and expanded outwardly using endless v groove as basic point, after making to hold out against swivel nut spinning in place by interior hexagonal groove, pipe cap master
The back taper on external wall top is deformed into cylinder and is close on pipe part inwall, and pipe cap main body and pipe part are fastened on
Together.
The outer wall top of the pipe cap main body and it is evenly distributed six U-shaped breach.
The top for holding out against swivel nut has lightening hole.
The present invention has the advantage that and effect compared with prior art：
1st, pipe cap main body is coordinated with holding out against swivel nut using screw thread, is held out against position for linear contact lay, is improved normal pressure, pipe cap master
At the top of body after being radially expanded, realize that face is engaged with tube wall, increase contact surface, improve friction effect, can substantially reduce
The risk that comes off of pipe cap, it is ensured that the safety and stability of electrification railway contact net.
2nd, swivel nut is held out against provided with interior hexagonal torque spanner interface, facilitates detaching products.Tightening moment, specification production are given simultaneously
The installation of product.

Embodiment
The specific embodiment of the present invention is described in detail with reference to accompanying drawing 1-5.
A kind of run-resistant pipe cap, by pipe cap main body 1 and holds out against swivel nut 2 and constitutes；The outer wall lower end of the pipe cap main body 1 is outside
Outer circular edge 8 is extended with, makes to form an annular mounting groove 3, pipe cap between the bottom outer wall of pipe cap main body 1 and outer circular edge 8
The outer wall top of main body 1 is in back taper, and is evenly distributed in the middle part of six U-shaped breach 7, the outer wall of pipe cap main body 1 with ring-type V
Type groove 6, and make the bottom of endless v groove 6 and the bottom insertion of U-shaped breach 7；The endoporus bottom tool of the pipe cap main body 1
There is internal thread 4, the endoporus top of pipe cap main body 1 has ring-type arc cam 5；The outer wall bottom for holding out against swivel nut 2 has
External screw thread 9, the outer wall top for holding out against swivel nut 2 is in be formed with interior hexagonal groove 10 on back taper, the lower surface for holding out against swivel nut 2；It is described
Hold out against swivel nut 2 and spinning is coordinated in the endoporus of pipe cap main body 1 by external screw thread 9 and the internal thread 4, and by holding out against swivel nut 2
The ring-type arc cam 5 that the endoporus top of back taper extruded tube cap main body 1 on outer wall top has, makes the top of pipe cap main body 1
Separate and expanded outwardly with endless v groove 6 for basic point along U-shaped breach 7, revolved when making to hold out against swivel nut 2 by interior hexagonal groove 10
It is attached to behind position, the back taper on the outer wall top of pipe cap main body 1 is deformed into cylinder and is close on the inwall of pipe part 12, by pipe cap master
Body 1 tightens together with pipe part 12.The top for holding out against swivel nut 2 has lightening hole 11.
In use, pipe cap main body 1 is sleeved on into the end of pipe part 12 by mounting groove 3 first, then using interior hexagonal
Torque spanner will hold out against the spinning of swivel nut 2 in the endoporus of pipe cap main body 1 by interior hexagonal groove 10, with the shifting for holding out against swivel nut 2
Dynamic, the back taper on its outer wall top starts the ring-type arc cam 5 that the endoporus top of extruded tube cap main body 1 has, and gradually makes pipe
The top of cap main body 1 is separated along U-shaped breach 7 and expanded outwardly with endless v groove 6 for basic point, is incited somebody to action when by regulation Tightening moment
After holding out against the spinning of swivel nut 2 in place, the back taper on the outer wall top of pipe cap main body 1 is deformed into cylinder and is close to the inwall of pipe part 12
On, pipe cap main body 1 is tightened together with pipe part 12, installation.
Above-described embodiment, simply presently preferred embodiments of the present invention, not for limiting the scope of the present invention, thus it is all with this
The equivalent variations that content described in invention claim is done, all should be included within scope of the invention as claimed.
