Abstract
Disclosed is an oil passing bolt of a hydraulic switch, solving the problem that a conventional bolt is poor in sealing performance. The oil passing bolt comprises a bolt body. The bolt body is provided with an accommodating cavity. The surface of the bolt body is provided with an oil through hole communicating with the accommodating cavity. The accommodating cavity is internally provided with a positioning boss. The beneficial effects of the utility model are that the positioning boss is additionally arranged so that when the bolt is fitted with other parts, the other parts can be assembled conveniently and a very good positioning effect can be realized; and simultaneously, the sealing performance of the bolt can be guaranteed in a very good manner, and the phenomena of oil leakage and the like can be prevented.
Description
Technical field
The utility model relates to a kind of hydraulic selector, is specifically related to a kind of oil draining bolt of crossing of hydraulic selector.
Background technology
Brake lamp switch is motor vehicle prompting back vehicle when deceleration, brake, avoids occuring the safety device that traffic is knocked into the back.Existing brake light switch of motor vehicle all is mechanical switch, and its structure comprises the bolt of hollow, and bolt links to each other with barred body, is provided with the contact in the bolt, and is switched on or switched off the tactile bridge of contact, promotes to touch bridge joint logical push rod or lever and back-moving spring.When brake, push rod or lever move, and touch the elastic force conducting contact of bridge customer service spring, and stop lamp is bright; During releasing of brake, touch the bridge stop lamp that under the effect of spring force, resets and extinguish.Yet the brake of motor vehicle is very frequent, and mechanical type compressing formula is connected, and easily causes fatigue for a long time and causes contacting conduction property and descend, and affects the normal braking lamp to light, and causes potential safety hazard; Secondly the mechanical switch reaction is sensitive not, fails during brake in time so that stop lamp is lighted, and has potential safety hazard.And existing hydraulic switch, the internal structure of its bolt is fairly simple, and sealing property is bad, has the phenomenons such as leakage of oil, has potential safety hazard.
Summary of the invention
For solving the existing bad problem of bolt seal performance of background technology, the utility model provides a kind of oil draining bolt of crossing of hydraulic selector.
The technical solution of the utility model is: a kind of excessively oil draining bolt of hydraulic selector, comprise bolt body, and described bolt body is provided with containing cavity, and the surface of described bolt body is provided with the oil through that communicates with containing cavity, is provided with positioning boss in the described containing cavity.
As a kind of improvement of the present utility model, the inwall of described containing cavity is provided with step, and described positioning boss is located on the step.
Advance a kind of improvement as of the present utility model, described positioning boss is annular.
Advance a kind of improvement as of the present utility model, the head of described bolt body is provided with bending part.
The beneficial effects of the utility model are, have increased positioning boss, so that bolt is when cooperating with miscellaneous part, miscellaneous part can easily assemble, and plays good locating effect, can also well guarantee the sealing property of product simultaneously, avoids existing the phenomenons such as leakage of oil.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model embodiment.
Cutaway view when accompanying drawing 2 uses for the utility model.
Cutaway view when accompanying drawing 3 does not use for the utility model.
Accompanying drawing 4 is the enlarged drawing at A place in the accompanying drawing 3.
Among the figure, 1, bolt body; 2, containing cavity; 3, oil through; 4, positioning boss; 5, step; 6, bending part.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described further:
By Fig. 1 in conjunction with shown in Fig. 2,3,4, a kind of excessively oil draining bolt of hydraulic selector comprises bolt body 1, and described bolt body 1 is provided with containing cavity 2, the surface of described bolt body 1 is provided with the oil through 3 that communicates with containing cavity 2, is provided with positioning boss 4 in the described containing cavity 2.The beneficial effects of the utility model are, have increased positioning boss, so that bolt is when cooperating with the hydraulic selector assembly, the hydraulic selector assembly can easily assemble, play good locating effect, can also well guarantee the sealing property of product simultaneously, avoid existing the phenomenons such as leakage of oil.
The inwall of described containing cavity 2 is provided with step 5, and described positioning boss 4 is located on the step 5.Certainly in the utility model, step 5 numbers can be one, two or three, are used for laying the miscellaneous part of hydraulic selector.Described positioning boss 4 is annular.Such structure can effectively cooperate with other parts, realizes sealing.
The head of described bolt body 1 is provided with bending part 6.Such structure is more conducive to the fixing of hydraulic selector assembly.
Every technical staff's notice: although the utility model describes according to above-mentioned embodiment; but invention thought of the present utility model is not limited in this utility model; the repacking of any utilization inventive concept all will be included in this patent scope of patent protection.
