Abstract
The utility model provides a sealing plug used for a vacuum booster of a passenger car, comprising a sealing plug body (1). A circumferential groove (2) is arranged on the outer circumference of the sealing plug body (1) and is as deep as 2mm to 3mm; and the front end of the sealing plug body (1) has a conical structure. In the sealing plug, the circumferential groove is arranged on the outer circumference of the sealing plug body, and the sealing plug is firmly clamped on a shell of the vacuum booster by the groove, so that the sealing plug can be ensured to not drop in working, a front cavity of the vacuum cavity can be ensured to be thoroughly vacuumized, and the working stability and the reliability of the sealing plug can be enhanced, thereby realizing a good sealing effect and avoiding potential safety hazards in the prior art due to the dropping of the sealing plug in the working; and due to the conical structure of the front end of the sealing plug, the sealing plug can be assembled on the shell more conveniently and the operability of the sealing plug is improved.
Description
Technical field
The utility model relates to technical field of sealing technology, is specifically related to a kind of car vacuum booster and uses sealing plug.
Background technique
In brake system of car; Vacuum hose on the air inlet tracheae links to each other with the vacuum valve of automobile vacuum booster; The vacuum action of air inlet tracheae is on vacuum booster during engine running; Thereby reach the effect of braking, sealing plug is used to realize the seal action between vacuum valve seat and the vacuum booster.In concrete installation process, the excircle of sealing plug and vacuum booster housing seal, the sealing plug inner circumference be used to seal and vacuum hose between the gap.Sealing plug is the important safety part in the braking system, and the operating temperature range of its permission is-40 degrees centigrade to+100 degrees centigrade, can bear maximum temperature when braking work continuously and be+120 degree.
In the existing technology, the less stable of the fixed connection structure of sealing plug and vacuum booster, sealing plug is easy to break away from from vacuum booster, and its seal action in braking system lost efficacy, and had bigger potential safety hazard.Seal action based on sealing plug plays critical effect in Motor Vehicle Braking Procedure, obtain that sealability is good, working stability and the high sealing plug of reliability, is the technical problem that those skilled in the art are badly in need of solving.
The model utility content
To above defective, the utility model provides the car vacuum booster that a kind of working stability and reliability are high, sealability is superior and use sealing plug.
For realizing above-mentioned purpose, the utility model is realized through following technological scheme:
A kind of car vacuum booster is used sealing plug, comprises sealing plug body (1), and circumferential groove 2 is set on the excircle of sealing plug body 1, and the degree of depth of groove 2 is 2 to 3 millimeters, and the front end of sealing plug body 1 is a cone structure.
Preferably, the degree of depth of groove 2 is 2.5 millimeters.
Preferably, sealing plug is processed by the EPDM rubber material.
Compared with prior art, the utlity model has following beneficial effect:
A kind of car vacuum booster that the utility model proposes is with in the sealing plug; Sealing plug plays the effect of sealed vacuum power-assisted, makes to produce vacuum in the vacuum booster to realize braking effect, and circumferential groove is set on the excircle of sealing plug body; Sealing plug is stuck in securely on the housing of vacuum booster through groove; Guarantee that sealing plug does not come off when work, can guarantee thoroughly to be vacuumized in the preceding die cavity of vacuum booster, improved the working stability and the reliability of sealing plug; Thereby obtain good sealing effect, avoided the potential safety hazard that sealing plug comes off and produced in the course of the work in the existing technology.On the other hand, the Front-end Design of sealing plug is a cone structure, helps the assembly manipulation of sealing plug on housing more, has improved operability.
Description of drawings
According to embodiment and accompanying drawing the utility model is done further explain below.
A kind of car vacuum booster that Fig. 1 proposes for the utility model is with the three-dimensional structure diagram of sealing plug.
Fig. 2 is the sectional view of sealing plug among Fig. 1.
Reference character: 1, the sealing plug body; 2, groove.
Embodiment
A kind of car vacuum booster that proposes for the utility model shown in Figure 1 is with the three-dimensional structure diagram of sealing plug, and Fig. 2 is a kind of car vacuum booster of the utility model proposition sectional view with sealing plug.
With reference to accompanying drawing, the utility model embodiment's car vacuum booster is used sealing plug, comprises sealing plug body 1, and circumferential groove 2 is set on the excircle of sealing plug body 1, and the degree of depth of groove 2 is 2 to 3 millimeters, and preferred, the degree of depth of groove 2 is 2.5 millimeters.On the other hand.The front end of sealing plug body 1 is a cone structure.Sealing plug plays the effect of sealed vacuum power-assisted; Make and produce vacuum in the vacuum booster to realize braking effect; Circumferential groove is set on the excircle of sealing plug body, sealing plug is stuck on the housing of vacuum booster securely, guarantee that sealing plug does not come off when work through groove; Can guarantee thoroughly to be vacuumized in the preceding die cavity of vacuum booster; Improve the working stability and the reliability of sealing plug, thereby obtained good sealing effect, avoided the potential safety hazard that sealing plug comes off and produced in the course of the work in the existing technology.The Front-end Design of sealing plug is a cone structure, helps the assembly manipulation of sealing plug on housing more, has improved operability.
The material selection EPDM rubber material of sealing plug in the utility model, production process adopts die press technology for forming, and its manufacturing mechanism is less demanding, and is with low cost.Mould adopts the multimode cave mode of production in specific operation, and the production capacity of single secondary mould is high, adopts strip profiled member material loading; Material loading time and auxiliary time are short; Justifying pull-up during product stripping, stripping rate is fast, and manufacturing efficiency is high; The loss of heat energy consumption when reducing sulfuration simultaneously, the stability of assurance quality of product.Behind the sulfidization molding, directly wash out the cylindrical overlap with special-purpose stamping knife, interior round torn edges is operated, and has guaranteed the performance of sealing plug the colleague who has improved manufacturing efficiency.
Combine accompanying drawing that the utility model has been carried out exemplary description above; Obviously the realization of the utility model does not receive the restriction of aforesaid way; As long as adopted method design of the utility model and the various improvement that technological scheme is carried out; Or the design of the utility model and technological scheme are directly applied to other occasion without improving, all in the protection domain of the utility model.
