Abstract
The utility model discloses a car check bolt, including bolt body and screwed pipe, the bolt body is a bottom downward bulge shape external screw thread pole of six cylinder structures, bolt body, the screwed pipe outside is equipped with the external screw thread, is equipped with the internal thread hole with external screw thread pole looks adaptation in its top for make the bolt body fix the top at the screwed pipe, internal thread hole bottom portion is equipped with and orders about screwed pipe pivoted fixed orifices recess, be equipped with locking pad between bolt body bottom and the screwed pipe top surface. The utility model provides a check bolt jolts vibration and the brake repeated load when strikeing at the car still can keep fastening dress attitude down, and rusts at the nut, through separable bolt body when being difficult to dismantle, utilizes interior hexagonal recess in the screwed pipe to pass through the hexagonal spanner with the screwed pipe dismantlement of check bolt, and the effect is obvious, and is simple and convenient.
Description
Technical field
The utility model belongs to automobile manufacturing field, particularly a kind of automobile chek bolt.
Background technique
At present, my automobile possesses total amount always in continuous increase, automobile assemble time chassis time, in order to dismounting is convenient in maintenance in the future, the fastening means of chassis bolt plain bolt+nut substantially, but the fastening means of plain bolt+nut easily produces loosening under the alternate load of automobile when pitch and brake impact, and existing nut gets rusty easily when exposing to the weather, once rust stubbornly refuses only to dismantle inconvenience but also may cause bolt fracture of wire situation, affect the maintenance service efficiency of automobile.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide that a kind of reasonable in design, long service life, tightness are good, convenient disassembly and have the new automobile chek bolt of good locking functions.
Technological scheme:
A kind of automobile chek bolt, comprise bolt body and threaded pipe, described bolt body is six column structures, and the bottom of described bolt body protrudes shape one external thread rod downwards; Be provided with outside thread outside described threaded pipe, in its top, be provided with the interior threaded hole suitable with described external thread rod, in order to the top making described bolt body be fixed on described threaded pipe; The fixed hole groove that can order about described rotated threaded tubular is provided with bottom described interior threaded hole; Locking pad is provided with bottom described bolt body and between described threaded pipe top surface.
Described locking pad sidewall is cone ramp structure, and described cone inclined-plane is arranged downwards.
Described fixed hole groove is interior hexagonal groove.
Locking spring is provided with bottom described external thread rod and between described fixed hole groove.
Technique effect:
The utility model provides a kind of automobile chek bolt, and compared to the prior art, the utility model has following beneficial effect:
1, a kind of automobile chek bolt, comprise bolt body and threaded pipe, bolt body is six column structures, conveniently carries out tightening operation by instruments such as spanners, the bottom of bolt body protrudes shape one external thread rod downwards, and bolt body and threaded pipe become one structure; Outside thread is provided with, for needing in the tapped hole fixed or being undertaken clamping by nut outside threaded pipe.The interior threaded hole suitable with external thread rod is provided with, in order to the top making bolt body be fixed on threaded pipe in the top of threaded pipe; Be provided with the fixed hole groove that can order about rotated threaded tubular bottom interior threaded hole, fastened tools can be used to carry out screw threads for fastening; Be provided with locking pad bottom bolt body and between threaded pipe top surface, locking pad, by pressurized, effectively prevents loosening of bolt body.
Locking pad sidewall is cone ramp structure, bores inclined-plane and arranges downwards, and after cone inclined-plane pressurized, relaxation effect is better.
Fixed hole groove is interior hexagonal groove, is convenient to carry out operation that is fastening or dismounting by hexagon wrench.
Locking spring is provided with, further strengthening stud anti-loosing effect originally bottom external thread rod and between fixed hole groove.
The utility model can allow chek bolt automobile bumpiness vibration and brake impact time alternate load under still keep fastening dress state, and get rusty at nut, by separable bolt body when being difficult to dismantle, the interior hexagonal groove in threaded pipe is utilized to be dismantled by the threaded pipe of chek bolt by hexagon wrench, successful, simple and convenient.
