Abstract
The invention discloses a hanging pipe type automobile rear axle vent plug, which comprises a plug body consisting of a plug rod and a plug head, wherein a first vent channel and a second vent channel which are communicated with each other are respectively arranged in the plug rod and the plug head, and the hanging pipe type automobile rear axle vent plug is characterized in that: the device also comprises a ventilation connecting rod and a soft hanging pipe, wherein a third ventilation passage is arranged in the ventilation connecting rod, one end of the soft hanging pipe is connected with one end of the ventilation connecting rod and is communicated with the third ventilation passage, and the other end of the ventilation connecting rod is connected with the plug head and is communicated with the second ventilation passage. The invention can not only prevent the rear axle from being polluted by the oil mist dropping out along the air duct in the rear axle, but also prevent the gear oil of the rear axle from deteriorating as the spray enters the rear axle along the air duct, and has the advantages of simple structure and convenient installation.
Description
Technical field
The present invention relates to vehicle rear axle ventilation plug.
Background technology
The effect of vehicle rear axle ventilation plug is when stopping up the back axle air extractor vent, also will keep the back axle and the external world to be in aeration status; Therefore; Existing vehicle rear axle ventilation plug generally includes the cock body that is made up of stopper rod and chock plug, becket and the loam cake that prevents the reverse inflow of extraneous dust granule, is respectively equipped with first air passage and second air passage that are interconnected in said stopper rod and the chock plug.Because its unreasonable structure, make it have following deficiency, 1, the mist of oil in the back axle very easily oozes and attached on the rear axle case along air passage, thus influence the cleaning and the outward appearance of back axle; 2, when back axle is paddled, the spray that splashes is prone to oppositely get in the back axle along air passage, causes the gear oil of back axle rotten, influences the service life of gear.
Summary of the invention
The objective of the invention is to above-mentioned deficiency provide a kind of simple in structure, easy for installation, not only can avoid that mist of oil oozes but also can prevent that spray from getting into the swing pipe formula vehicle rear axle ventilation plug in the back axle in the back axle.
The present invention includes the cock body that constitutes by stopper rod and chock plug; Be respectively equipped with first air passage and second air passage that are interconnected in said stopper rod and the chock plug; It is characterized in that: the soft swing pipe that the ventilation connecting rod that is provided with the 3rd air passage in also comprising and an end and ventilation connecting rod one end are connected and are communicated with the 3rd air passage, the other end of said ventilation connecting rod is connected with chock plug and is communicated with second air passage.
In the technique scheme, also comprise fixing hoop, an end of said ventilation connecting rod is connected with an end of soft swing pipe through fixing hoop.
In the technique scheme, said stopper rod also is provided with outside thread.
The present invention is through being provided with ventilation connecting rod and soft swing pipe; Can be easily the air passage exit end of cock body be moved to the place away from rear axle case; Thereby both can avoid in the back axle mist of oil to ooze and pollute back axle along air passage; Can prevent that again spray from getting in the back axle and to cause the gear oil of back axle rotten along air passage, has simple in structure, convenient installation.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the cock body structural representation.
Fig. 3 is a running condition scheme drawing of the present invention.
Among the figure: 1-cock body (11-stopper rod, 111-first air passage, 112-outside thread, 12-chock plug, 121-second air passage), 2-ventilation connecting rod (21-the 3rd air passage), the soft swing pipe of 3-, 4-fixing hoop, 5-rear axle case (51-back axle air extractor vent).
The specific embodiment
Further specify the present invention below in conjunction with accompanying drawing and embodiment.
Embodiment: the present invention includes the cock body 1, ventilation connecting rod 2, soft swing pipe 3 and the fixing hoop 4 that constitute by stopper rod 11 and chock plug 12; Wherein, Be respectively equipped with first air passage 111 and second air passage 121 that is interconnected in said stopper rod 11 and the chock plug 12; Said stopper rod 11 also is provided with outside thread 112, is provided with the 3rd air passage 21 in the said ventilation connecting rod 2, and said soft swing pipe 3 adopts rubber tube; The one of which end is connected and is communicated with the 3rd air passage 21 with ventilation connecting rod 2 one ends through fixing hoop 4, and the other end of said ventilation connecting rod 2 is connected with chock plug 12 and is communicated with second air passage 121.
During installation, earlier the outside thread 112 through stopper rod 11 is connected cock body 1 with the back axle air extractor vent 51 of rear axle case 5, and the place that then other end of soft swing pipe 3 is fixed on away from rear axle case 5 gets final product.
