Abstract
The utility model discloses a kind of enhanced rubber plug cocks, it includes plug cock ontology and copper skeleton, the central axis of the plug cock ontology is equipped with oiling through-hole, the top of the plug cock ontology has a primary seal lip, there is the sealing pair lip of an evagination, the copper skeleton to be arranged at the middle part of the plug cock ontology for the middle and lower part of the plug cock ontology；The copper skeleton is copper pipe section, the inner wall of the copper skeleton and upper and lower end face and the bulk sulfided bonding of the plug cock, and the outer wall of the copper skeleton is exposed；The outer diameter of the primary seal lip is gradually reduced and from up to down more than the outer diameter of the copper skeleton and the sealing pair lip；At the maximum outside diameter of the sealing pair lip guide sliding part is formed between the bottom outer side of the plug cock ontology.The rubber oil plug structural strength height of the utility model is filled in securely, and cracky, double sealing effect be not good.
Description
Technical field
The utility model is related to a kind of enhanced rubber plug cocks, belong to field of rubber technology.
Background technology
The main function of rubber oil plug is to be sealed, block to the hydraulic fluid port of oil cylinder, fuel tank.To ensure sealing effect, oil
Plug is installed with hydraulic fluid port majority using interference fit.It is difficult to install if interference is excessive, it strongly fills in, easily leads to plug cock breakage；If
Interference is too small, and is difficult to ensure complete sealing surface, and sealing effect is poor, Shortcomings.
Utility model content
Against the above deficiency, the utility model provides a kind of enhanced rubber plug cock.
Technical solution used by the utility model is：
A kind of enhanced rubber plug cock comprising plug cock ontology and copper skeleton are set on the central axis of the plug cock ontology
There are oiling through-hole, the top of the plug cock ontology that there is a primary seal lip, the middle and lower part of the plug cock ontology to have an evagination
Sealing pair lip, the copper skeleton are arranged at the middle part of the plug cock ontology；The copper skeleton be copper pipe section, the copper skeleton it is interior
Wall and upper and lower end face and the bulk sulfided bonding of the plug cock, the outer wall of the copper skeleton are exposed；The primary seal lip it is outer without leave
On be gradually reduced downwards and more than the copper skeleton and the sealing pair lip outer diameter；At the maximum outside diameter of the sealing pair lip with
Guide sliding part is formed between the bottom outer side of the plug cock ontology.
The utility model has the advantage of：The rubber oil plug of the utility model has copper skeleton, and structural strength is high, fills in jail
Gu not cracky；Have primary seal lip and secondary sealing lip, double sealing effect are good.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
Embodiment：
As shown in Figure 1, a kind of enhanced rubber plug cock comprising plug cock ontology (1) and copper skeleton (2), the plug cock sheet
The central axis of body (1) is equipped with oiling through-hole (3), and the top of the plug cock ontology (1) has a primary seal lip (4), described
There is the sealing pair lip (5) of an evagination, the copper skeleton (2) to be arranged in the plug cock ontology (1) for the middle and lower part of plug cock ontology (1)
Middle part；The copper skeleton (2) is copper pipe section, the inner wall of the copper skeleton (2) and upper and lower end face and plug cock ontology (1) sulphur
Change bonding, the outer wall of the copper skeleton (2) is exposed；The outer diameter of the primary seal lip (4) is gradually reduced and is more than institute from up to down
State the outer diameter of copper skeleton (2) and the sealing pair lip (5)；At the maximum outside diameter of the sealing pair lip (5) with the plug cock ontology
(1) guide sliding part (6) is formed between bottom outer side.
The rubber oil plug of the utility model has copper skeleton, and structural strength is high, fills in securely, not cracky；Has primary seal
Lip and secondary sealing lip, double sealing effect are good.
The above is preferred embodiments of the present invention, it is noted that for the ordinary skill of the art
For personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these are improved and profit
Decorations are also considered as the scope of protection of the utility model.
