Description
Technical field
A kind of bolt of present invention design, more particularly to a kind of pulling force regulating bolt.
Background technology
In machinery equipment field, it is often necessary to the spacing in adjustment equipment between two parts.For some precision equipments
Through frequently with special spacing adjusting device, the generally complicated cost of these special purpose devices is high；For degree of regulation requirement not
It is very high equipment, generally using manually adjusting by rule of thumb, regulation error is generally larger, and high to workman's technical requirements.
The content of the invention
The present invention proposes a kind of pulling force regulating bolt, and the regulation machinery that solution in the prior art can not be accurate and inexpensive is set
Between standby two parts the problem of spacing.
Pulling force regulating bolt, including upper bolt and lower bolt, the top of upper bolt are provided with connection screw thread, and bottom is provided with
The positioning key of protrusion；The bottom of the lower bolt is provided with connection screw thread, the axially disposed regulating tank for having spacing equal in top,
The positioning key of upper bolt can in regulating tank any adjusting position；The regulating tank is the top for being radially disposed at lower bolt；
The top of the lower bolt is set for hollow tubular.
The regulating tank includes being arranged above and below lower bolt tubulose side wall and axially disposed axial trough, the both sides of axial trough
It is arranged alternately multiple keyways being arranged circumferentially.
The keyway is provided with locked groove close to axial trough side.
The locked groove is set for ellipse.
The axial trough bottom is provided with the ring lock that can be moved up and down and be set in along axial trough on lower bolt.
The ring, which is locked, is provided with a locking key, and locking key is arranged in axial trough.
The locking key is set for ellipse, including two ends hollow out oval lock body and buried engraved at oval lock body two ends
Semicircle tapered end in sky；Oval lock body is ejected by spring supporting and part between semicircle tapered end.
The oval lock body is highly less than keyway and is highly less than locking key whole height.
The upper diameter of bolt is less than lower bolt annular diameters.
Compared with prior art, have the advantage that for：Using the regulating tank set between two, bolt up and down, pass through
The height of spacing and adjusting nut and bolt between regulating bolt connection, reaches the high precision pull regulation of bolt, ring lock
Setting can ensure that bolt prevents the positioning key of bolt from coming off after adjusting position, cause accident.
Brief description of the drawings
Fig. 1 is the structural representation of pulling force regulating bolt of the present invention；
Fig. 2 is the sectional view of locking key of the present invention.
Embodiment
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
There is the accompanying drawing used required in technology description to be briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments of invention, for those of ordinary skill in the art, without having to pay creative labor, may be used also
To obtain other accompanying drawings according to these accompanying drawings.
Be illustrated as a kind of embodiment of pulling force regulating bolt of the present invention, including upper bolt 1 and the lower bolt of spiral shell 2, upper bolt it is upper
Portion is provided with connection screw thread, and bottom is provided with the positioning key 11 of protrusion；The bottom of the lower bolt is provided with connection screw thread, top
The axially disposed regulating tank for having spacing equal, the positioning key of upper bolt can in regulating tank any adjusting position；It is described to adjust
It is the top both sides for being radially disposed at lower bolt to save groove；The top of the lower bolt is set for hollow tubular, and upper bolt bottom can
To be located in the tubulus of lower bolt.
Further, the regulating tank includes being arranged at lower bolt tubulose side wall and axially disposed axial trough 21, axle
The both sides of groove are provided with multiple keyways 22 being arranged circumferentially alternatively up and down.
Further, the keyway is provided with locked groove 23 close to axial trough side.
Further, the locked groove is set for ellipse.
Further, the axial trough bottom is provided with the ring lock that can be moved up and down and be set in along axial trough on lower bolt
24。
Further, the ring, which is locked, is provided with a locking key 25, and locking key is arranged in axial trough.
Further, the locking key is set for ellipse, including the oval lock body 251 of two ends hollow out and buried in ellipse
Semicircle tapered end 252 in the hollow out of shape lock body two ends；Pass through the support of spring 253 and part ejection ellipse between semicircle tapered end
Lock body.
Further, the oval lock body is highly less than keyway and is highly less than locking key whole height.
Further, the upper diameter of bolt is less than lower bolt annular diameters.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent substitution and improvements made etc. should be included in the scope of the protection.
