Abstract
The utility model discloses an oiling bolt, including integrative head and the threaded rod that sets up, the oil filler point has been seted up to the threaded rod on being close to the periphery of head, the oil outlet has been seted up to the bottom of threaded rod, oil outlet and oil filler point are scaled up towards the oil outlet by the oil filler point through drainage groove UNICOM, the sectional area in drainage groove. The threaded rod on seted up oil filler point and oil outlet respectively, and oil filler point and oil outlet realize the UNICOM borrowing this structure through the drainage groove, the effect of realization oil addition that can be fine, and the oil filler point in this technical scheme is seted up on the periphery of threaded rod, so, twisting the bolt go into the object, can be fine general the oil filler point hide, avoid its influence that receives too much impurity dust, and the oil filler point be close to the head again and set up, consequently as long as back -out the bolt slightly, just can expose the oil filler point, realize the interpolation purpose.
Description
Technical field
The utility model relates to a kind of fit sealing part, and more particularly, it relates to a kind of plug screw.
Background technique
Bolt is by bolt head and screw rod (with an externally threaded cylindrical body) class fastening piece dimerous, for being fastenedly connected two mechanical machine part with through hole.Bolt daily life when in and in panel beating and machine tooling technical field in the middle of, be absolutely necessary, but in moister, the metal object that bolt is connected with it is easy to get rusty, bolt is caused to unload to get off, cause unnecessary trouble, affect working efficiency, delay the normal operation of machinery.
Application number is the Chinese patent " a kind of bolt " of 201310347208.6, disclose a kind of bolt, it is characterized in that, described bolt comprises: nut and screw rod, described nut is provided with through hole along axis, described screw rod is provided with oil-feed tank along axis, described oil-feed tank extends to described screw rod end, described oil-feed tank is communicated with described tapped hole, the described screw rod body of rod is provided with at least one oil outlet, although this scheme achieves the antirust object of oiling, but because through hole is directly in communication with the outside, make lubricant oil can by external environment condition to contamination and deterioration, through hole also easily puts aside upper impurity.
In order to solve the problem, application number is the Chinese patent " a kind of Novel bolt " of 201110368127.5, by with the addition of rubber stopper, the effect that lubricant oil is isolated from the outside, lubricant oil is made to remain clean, but this technological scheme one adds processing cost, two carry out rubber stopper is also easy to lose in the process used.
The technical program is intended to propose corresponding solution for the problems referred to above.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of structure simple and can avoids the oiling bolt of lubricant oil and the upper impurity of oil hole savings.
For achieving the above object, a kind of oiling bolt, comprises the head and threaded stem that are wholely set, described threaded stem near head circumferential surface on offer oil hole; The bottom of threaded stem offers oil outlet; Oil outlet and oil hole are by drainage trough UNICOM, and the sectional area of drainage trough is increased progressively towards oil outlet by oil hole.
This programme is set to further: the curved vibrational power flow of opening of described oil hole.
This programme is set to further: described oil hole at least includes two, and is uniformly distributed on the circumferential surface of threaded stem.
This programme is set to further: the inwall of drainage trough is provided with buffer structure.
This programme is set to further: described buffer structure is be arranged at drainage trough inwall receives layer.
By adopting technique scheme, due in the technical program, described threaded stem offers oil hole and oil outlet respectively, and described oil hole and oil outlet realize UNICOM by drainage trough, structure whereby, the effect of adding lubricant oil can well be realized, and the oil hole in the technical program is opened on the circumferential surface of threaded stem, so, bolt is being screwed into object, well described oil hole can be stashed, it is avoided to be subject to the impact of too much impurity dust, and described oil hole is offered near head, as long as therefore slightly bolt is back-outed, just oil hole can be exposed, realize adding purpose.
In addition because the sectional area of drainage trough is increased progressively towards oil outlet by oil hole, so at the technique effect that can play the well certain lubricant oil of savings, optimize the technical program further.
Above-mentioned technological scheme well can not only realize the technique effect that will realize required by the utility model, and its structure is simple, is easy to actual machining operation.
Accompanying drawing explanation
Fig. 1 is the stereogram of a kind of oiling screw embodiment of the utility model;
Fig. 2 is the sectional view of a kind of oiling screw embodiment of the utility model.
In figure: 1, head; 2, threaded stem; 3, oil hole; 4, oil outlet; 5, drainage trough; 6, layer is received.
Embodiment
Referring to figs. 1 through Fig. 2, a kind of oiling screw embodiment of the utility model is described further.
A kind of oiling bolt, comprises the head 1 and threaded stem 2 that are wholely set, described threaded stem 2 near head 1 circumferential surface on offer oil hole 3; The bottom of threaded stem 2 offers oil outlet 4; Oil outlet 4 and oil hole 3 are by drainage trough 5 UNICOM, and the sectional area of drainage trough 5 is increased progressively towards oil outlet 4 by oil hole 3.
Due in the technical program, described threaded stem 2 offers respectively oil hole 3 and oil outlet 4, and described oil hole and oil outlet 4 realize UNICOM by drainage trough 5, structure whereby, the effect of adding lubricant oil can well be realized, and the oil hole 3 in the technical program is opened on the circumferential surface of threaded stem 2, so, bolt is being screwed into object, well described oil hole 3 can be stashed, it is avoided to be subject to the impact of too much impurity dust, and described oil hole 3 is offered near head 1, as long as therefore slightly bolt is back-outed, just can expose oil hole 3, realize adding purpose.
In addition because the sectional area of drainage trough 5 is increased progressively towards oil outlet 4 by oil hole 3, so at the technique effect that can play the well certain lubricant oil of savings, optimize the technical program further.
Above-mentioned technological scheme well can not only realize the technique effect that will realize required by the utility model, and its structure is simple, is easy to actual machining operation.
And in the technical program, the curved vibrational power flow of opening of described oil hole 3, can have one to guide effect concrete enforcement operator when adding, optimize the technical program further.
And bolt is when producing, we can not ensure oil hole 3 towards, therefore the use of multiple oil hole 3 meeting person easy to use is set, therefore in the technical program, described oil hole 3 is set at least include two by spy, and be uniformly distributed on the circumferential surface of threaded stem 2, but described oil hole 3 offers that number is unsuitable too much can be impacted the bulk strength of bolt, therefore preferably adopts 2 in the technical program.
And be optimize oiling effect further, spy is provided with buffer structure on the inwall of drainage trough 5, prevent the lubricant oil in it from flowing away too fast, further optimization the technical program, wherein said buffer structure is be arranged at drainage trough 5 inwall receives layer 6, and this receives layer 6 that sea etc. can be adopted to have the material necessarily receiving effect.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
