Description
Technical field
The utility model is related to a kind of bolt, particularly a kind of through type ventilation bolt.
Background technology
At present, ventilation bolt mostly using through type ventilation device, does not avoid transmission case inner engine oil from directly splashing simultaneously on the market
Blocking ventilation bolt bore leads to bolt permeability, and the oily labyrinth of gear need to be designed in transmission case, transmission case inner space is caused to increase,
And if be inverted in complete machine transportational process, machine oil can be from ventilation bolt hole leakage inside transmission case, need to be outside ventilation bolt
Portion installs closed facility additional, and cost is caused to increase.
Utility model content
The purpose of this utility model be just to provide it is a kind of can effectively prevent oil leak and compact-sized through type ventilation bolt.
The purpose of this utility model is that technical solution in this way is realized, a kind of through type is ventilated bolt, the spiral shell
Bolt includes the bolt column that hollow and one end is equipped with right-angled intersection through-hole, and the other end of the bolt column is provided with nuts；
Gear oil machine structure is provided in the bolt column, one end is provided in the nuts and withstands on nuts inner end wall, other end top
Spring on gear oil machine structure.
Wherein, the gear oil machine structure includes the plain washer, O-ring and the steel ball that are successively set on from top to bottom in bolt column,
Limited step A and limited step B are provided on the bolt column wall, setting is jagged at shown limited step B, described
O-ring is located on limited step A, and the steel ball is located on limited step B, and one end of the spring withstands on plain washer upper surface.
It is manufactured for the ease of connection, the nuts is fixed on by riveting on bolt column one end.
By adopting the above-described technical solution, the utility model has, of simple structure and low cost, service-strong is excellent
Point is not only able to ventilate using it, and effectively prevent its oil leakage when being driven carton upside down, compact-sized, has saved biography
Dynamic case cost and space.
Description of the drawings
The description of the drawings of the utility model is as follows：
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings, but the utility model
These embodiments are not limited to, any improvement or replacement on the present embodiment essence spirit still falls within the utility model
Claim range claimed.
Embodiment 1：As shown in Figure 1, a kind of through type ventilation bolt, the bolt include hollow and one end and are handed over equipped with cross
The bolt column 2 of through-hole 1 is pitched, the other end of the bolt column 2 is provided with nuts 3；Gear oil is provided in the bolt column 2
Mechanism is provided with one end in the nuts 3 and withstands on 3 inner end wall of nuts, and the other end withstands on the spring 4 on gear oil machine structure.
Wherein, the gear oil machine structure includes the plain washer being successively set on from top to bottom in bolt column 3（5）, 6 and of O-ring
Steel ball 7 is provided with limited step A8 and limited step B9 on 2 inner wall of bolt column, is set at shown limited step B9
Jagged 10, the O-ring 6 is located on limited step A8, and the steel ball 7 is located on limited step B9, one end of the spring 4
Withstand on 5 upper surface of plain washer.
Wherein, the nuts 3 is fixed on by riveting on 2 one end of bolt column.
The utility model works in this way：Ventilation bolt is mounted on transmission case, when transmission case forward direction is placed, steel
Pearl 7 is placed on limited step B9, since bolt column lower part is closed, can block the lubricating oil of splashing, lubricating oil is avoided directly to fly
Splashing endoporus causes endoporus to go out bolt of ventilating by lubricating oil blocking or lubricating oil splash；The air pressure inside formed in transmission case is led to
The notch 10 for crossing limited step B9 is expelled directly out, while steel ball 7 also functions to condensation to oil gas.
When being driven carton upside down, steel ball 7 is contacted and is bonded with O-ring 6 under the effect of gravity, since O-ring 6 exists
It is bonded under the action of 4 pretightning force of spring with limited step A8 so that sealing, transmission case internal lubrication are formed at 6 position of O-ring
Oil can not be from ventilation bolt bore outflow.
