Abstract
The utility model provides a kind of rubber oil plug of good airproof performance, comprises plug cock main body, it is characterized in that, described plug cock body upper surface is provided with concave structure, and described plug cock main body side has certain inclination angle towards interior, and described inclination angle is less than 15 degree.The beneficial effect that the utility model has is, plug cock has concave structure, the extruding of plug cock both sides can be pinched when mounted and just can be pressed into plug cock mouth easily, because plug cock main body is that rubber material has elasticity and returns to the original form thus compress plug cock mouth during relieving, because plug cock main body side has certain inclination angle towards interior, inclination angle is less than 15 degree, thus plug cock sidewall more easily extrudes mutually with plug cock mouth, and sealability is better.
Description
Technical field
The utility model relates to rubber part products field, is specially a kind of rubber oil plug of good airproof performance.
Background technique
Jack, English (Jack) is the simplest crane gear of a kind of lifting highly little (being less than 1m).It has mechanical type and hydraulic type two kinds.Jack is mainly used in the department such as factories and miness, communications and transportation as Mechanical Help and other work such as lifting, support.Its light structure is firm, flexibility and reliability, and a people can carry and operate.Jack, as a kind of using scope instrument widely, have employed top quality cast, ensure that quality and the working life of jack.The component of jack are many, and its middle sleeve is exactly one of them, and on sleeve pipe, general plug cock clogs plug cock mouth, and existing plug cock is generally solid structure and structure is perfect not, clog in the process of plug cock mouth compare effort at use plug cock.
Model utility content
Technical problem to be solved in the utility model designs the rubber oil plug of a kind of structure good airproof performance simple, easy for installation.
For solving the problems of the technologies described above, the utility model provides a kind of rubber oil plug of good airproof performance, comprises plug cock main body, it is characterized in that, described plug cock body upper surface is provided with concave structure, and described plug cock main body side has certain inclination angle towards interior, and described inclination angle is less than 15 degree.
Preferably, described concave structure is blind hole; Described blind hole is positioned at plug cock body upper surface middle.
Preferably, described blind hole is cylinder type.
Preferably, described concave structure is groove; Described groove is positioned at plug cock body upper surface middle.
Preferably, described groove is square.
Preferably, described plug cock main body is that rubber material is made.
The beneficial effect that the utility model has is, plug cock has concave structure, the extruding of plug cock both sides can be pinched when mounted and just can be pressed into plug cock mouth easily, because plug cock main body is that rubber material has elasticity and returns to the original form thus compress plug cock mouth during relieving, because plug cock main body side has certain inclination angle towards interior, inclination angle is less than 15 degree, thus plug cock sidewall more easily extrudes mutually with plug cock mouth, and sealability is better.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is further described in detail.
Fig. 1 is the integrally-built sectional view of the utility model;
Fig. 2 is the integrally-built plan view of the utility model.
In figure, 1 is plug cock main body, and 2 is concave structure.
Embodiment
The rubber oil plug of a kind of good airproof performance as shown in Figure 1 and Figure 2, comprises plug cock main body 1, and plug cock body upper surface is provided with concave structure 2, concave structure 2 is blind hole or groove, plug cock main body side has certain inclination angle towards interior, and inclination angle is less than 15 degree, and plug cock main body is that rubber material is made.
Plug cock is quality of rubber materials, when installing and using, blind hole is provided with or groove is hollow-core construction due to plug cock body upper surface, just plug cock mouth can be pressed into easily by pinching the extruding of plug cock both sides, because plug cock main body is that rubber material has elasticity and returns to the original form thus compress plug cock mouth during relieving, because plug cock main body side has certain inclination angle towards interior, inclination angle is less than 15 degree, thus plug cock sidewall more easily extrudes mutually with plug cock mouth, sealability is better.
It should be noted last that, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
