Description

A kind of adjustable bolt of screw-in depth
Technical field
The utility model is related to fastener areas more particularly to a kind of adjustable bolts of screw-in depth.
Background technology
It is common a kind of connection structure in existing machinery equipment to be bolted, and is primarily suitable for easy-to-dismount connector In, formed flexible connection, in the case where not destroying connected piece, easily connector can be dismantled, be conveniently replaceable or Person repairs.
In actual use, different connecting holes configures obstructed connection bolt.But in spiral shell of the prior art Bolt, in connection procedure, assembly crewman needs to select the bolt of different length according to the thickness of connector connector, meets it Requirement.This operation causes the defects of bolt uses, for the uncertain connection of connector thickness, is often required to take Different lengths bolt is repeatedly adapted to, and is then selected, and bolt length is subject to, using limitation, do not possess good versatility.
Utility model content
The purpose of this utility model is to provide a kind of adjustable bolt of screw-in depth, the company of suitable multi-thickness connector It connects, promotes versatility.
For this purpose, the utility model uses following technical scheme:
A kind of adjustable bolt of screw-in depth, including bolt head and outer bolt bar, one end of the outer bolt bar passes through Bolt head is concordant with bolt head other end face to be set, and other end extends outwardly, and the outer bolt bar is located at bolt head The one end in portion is arranged concentrically the blocking cap positioned at bolt head outer end face, and other end is provided with inner screw, the inner screw One end is screwed in inside outer bolt bar, and other end extends along outer bolt bar outer end, and one is provided between the blocking cap and inner screw Pipeline, the pipeline outside are provided with the compression spring between inner screw and blocking cap.
Wherein, outer circle of the naked leakage of the outer bolt bar in bolt head one end is provided with external screw thread, and inner wall whole process is provided with Internal thread.
Wherein, the pipeline is located at one end of blocking cap and is provided with spherical end cap.
Wherein, the inner screw is internally provided with the blind hole communicated with pipeline, and the outer circle of the inner screw is circumferentially evenly equipped with Several oil outlets being connected with blind hole.
Wherein, the outer bolt bar and bolt head integration machine-shaping.
Wherein, the length of the inner screw is 1.5 times of outer bolt pole length.
The beneficial effects of the utility model:A kind of adjustable bolt of screw-in depth, by inner screw inside outer shank of bolt Screw-in and back-out, be suitble to the connection of multi-thickness connector, and screw thread be formed simultaneously by outer bolt bar and inner screw and is connected It connects, is especially suitable for the connection with step orifice, improve bonding strength and reliability.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
The technical solution of the utility model is further illustrated with reference to Fig. 1 and by specific embodiment.
A kind of adjustable bolt of screw-in depth, including bolt head 1 and outer bolt bar 2, one end of the outer bolt bar 2 is worn Cross that bolt head 1 is concordant with 1 other end face of bolt head to be set, other end extends outwardly, and the outer bolt bar 2 is located at spiral shell One end of bolt head 1 is arranged concentrically the blocking cap 3 positioned at 1 outer end face of bolt head, and other end is provided with inner screw 4, blocking cap 3 It can prevent external dust or other sundries from entering 2 inner cavity of outer bolt bar, improve the cooperation of inner screw 4 and outer bolt bar 2.
One end of the inner screw 4 is screwed in inside outer bolt bar 2, and other end extends along 2 outer end of outer bolt bar, inner screw 4 screw in or screw out along 2 internal circumferential of outer bolt bar, reach the adjustable effect of depth.
A pipeline 5 is provided between the blocking cap 3 and inner screw 4,5 outside of pipeline is provided with positioned at 4 He of inner screw Compression spring 6 between blocking cap 3, compression spring 6 is with inner screw 4 to be welded to connect, and with blocking cap 3 to be freely connected, blocking cap 3 is inside During screw-in, inner screw 4 is formed outwardly against beneficial to the connection of inner screw 4, raising connection extruding force connects sealed reliable.
In the present embodiment, outer circle of the naked leakage of outer bolt bar 2 in 1 one end of bolt head is provided with external screw thread, and inner wall is complete Journey is provided with internal thread, is fixedly connected outside the formation of external screw rod bar 2 with connector, and inside forms the depth adjustment of inner screw 4.
In the present embodiment, one end that the pipeline 5 is located at blocking cap 3 is provided with spherical end cap 7, forms sealing, and pipeline 5 is led Pouring into for lubricating oil is used for, places and gets rusty between inner screw 4 and outer bolt bar 2.
In the present embodiment, the inner screw 4 is internally provided with the blind hole 41 communicated with pipeline 5, the outer circle of the inner screw 4 Circumferentially it is evenly equipped with several oil outlets 42 being connected with blind hole 41.
In the present embodiment, the outer bolt bar 2 and the integrated machine-shaping of bolt head 1 reduce processing program, improve and add Work efficiency rate.
In the present embodiment, the length of the inner screw 4 is 1.5 times of 2 length of outer bolt bar.
More than content is only the preferred embodiment of the utility model, for those of ordinary skill in the art, according to this reality With new thought, there will be changes, this specification content should not be construed as in specific embodiments and applications Limitation to the utility model.
