Abstract
The utility model relates to a bolt with a hole. A bolt body is provided with an axial oil guide hole in the axial direction of a bolt rod and provided with a radial oil guide hole in the radial direction, and the radial oil guide hole and the axial oil guide hole are communicated. The bolt is simple in structure, reasonable in design, and convenient to install and use; by adopting the structure that the oil guide holes are arranged inside the bolt body, the problem of 90-degree bending of an oil pipe can be effectively solved; the hexagonal bolt can provide stronger connection pre-tightening force to lead the connection to be reliable; and by adopting fine thread connection and a copper washer, the sealing property is good, the leakage of hydraulic oil can be effectively reduced, and the braking safety of vehicles can be improved.
Description
Technical field
The utility model relates to a kind of bolt, is a kind of eye bolt that oil pipe is connected with oil pump that is used for specifically.
Background technique
At present, the quality of the braking of automobile directly has influence on the Security of vehicle, and vehicle can produce bigger pressure in moment when braking, and because the variation of pressure is bigger, often the joining place at oil circuit produces leakage phenomenon, reduces the accuracy of braking.Simultaneously in the vehicle braked oil circuit, oil pipe is connected with pump, general common employing oil pipe directly links to each other with the hydraulic fluid port of oil pump, oil pipe connects when need carry out 90 degree bendings and turning to, can cause local compression excessive, easily produce obstruction and cause the oil circuit circulation not smooth, even can make oil pipe destroying infection proper functioning at the oil pipe bending part.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that exists in the above-mentioned technology, provides a kind of simple in structure, reasonable in design, easy for installation, and it is fastening, reliable that oil pipe is connected with oil pump, the eye bolt of good seal performance.
In order to achieve the above object, the technical solution adopted in the utility model is: described bolt body axially has axial oil guiding hole at bolt shank, radially also has radially oil guiding hole, and radially oil guiding hole communicates with axial oil guiding hole.
The utility model has the advantages that:
(1) simple in structure, reasonable in design, installation, easy to use, bolt body inside has the structure of oil guiding hole, can effectively solve oil pipe and connect 90 ° of bending problems;
(2) hexagon head bolt can provide bigger connection pretightening force, makes to connect reliably;
(3) use of connection of employing fine thread and copper washer makes favorable sealing property, can effectively reduce the leakage of hydraulic oil, increases the Security of car brakeing.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model work schematic representation.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
By Fig. 1-Fig. 2 as can be known, bolt body 1 described in the utility model axially has axial oil guiding hole 3 at bolt shank, radially also has radially oil guiding hole 2, and radially oil guiding hole 2 communicates with axial oil guiding hole 3.
Described bolt body 1 is a hexagon head bolt.
The utility model is in Fig. 1, and described bolt body 1 axially has axial oil guiding hole 3 at bolt shank, radially also has radially oil guiding hole 2, and radially oil guiding hole 2 communicates with axial oil guiding hole 3.Bolt head is the hexagon head form, and the nominal diameter of bolt has oil pump matrix tapped hole to determine.Screw thread 4 is a fine thread, and pitch is standard series, looks into thread standard and get final product after the bolt nominal diameter is determined.
Below in conjunction with Fig. 2 its working procedure is described: oil pipe is connected on the high-voltage tube assembly 5, eye bolt is screwed in the oil pump 7 matrix tapped holes by fine thread high-voltage tube assembly 5 is fixed, and make the axial oil guiding hole 3 of eye bolt corresponding with oil pump 7 oil outlets, radially oil guiding hole 2 is corresponding with high-voltage tube assembly 5 internal holes.All be added with copper washer 6 between high-voltage tube assembly 5 and bolt head and oil pump 7 matrixes simultaneously, the size of copper washer 6 matches with bolt, the copper washer 6 that connects when bolt is carried out pretension can guarantee to connect because of little distortion takes place in extruding that the end is not oozed, no leakage is pressed brake oil, has improved the reliability and the sealing that connect.During work, the oil that comes of oil pump 7 flow in the body of bolt to oil guiding hole 3 by bolt axis, because radially oil guiding hole 2 is connected with axial oil guiding hole 3, hydraulic oil flows out to high-voltage tube assembly 5 inside from oil guiding hole 2 radially, oil pipe connect with high-voltage tube assembly 5 on, thereby hydraulic oil flows in the oil pipe.Eye bolt when use installing and copper washer 6 be used.
Claims (2)
1. an eye bolt comprises bolt body (1), it is characterized in that: described bolt body (1) axially has axial oil guiding hole (3) at bolt shank, radially also has radially oil guiding hole (2), and radially oil guiding hole (2) communicates with axial oil guiding hole (3).
2. eye bolt according to claim 1 is characterized in that: described bolt body (1) is a hexagon head bolt.
