Abstract
The invention discloses a bolt special for a transmission device. The bolt comprises a head portion, a screw rod and an outer bearing rod. A bearing cavity is formed in the head portion, and a ring of internal threads is arranged in the bearing cavity; the screw rod is connected with the head portion, and external threads are arranged on the screw rod; the outer bearing rod is fixed to the head portion through the internal threads, and the end of the outer bearing rod serves as an operation portion; the operation portion is in a flat shape, and a machining groove is formed in the inner side of the flat-shaped operation portion; and the machining groove is a cross-shaped groove body. The bearing cavity is formed in the head portion of the bolt, and the outer bearing rod is fixed to the bearing cavity; the operation length of the bolt is extended through the outer bearing rod, and the machining groove in the end of the outer bearing rod is the cross-shaped groove body; and a hexagonal sleeve tool or a straight-line or cross tool can be used in the machining groove and is convenient to dismount and mount. The bolt has the advantages of being simple in structure and convenient to use.
Description
Technical field
The present invention relates to transmission device field, be specifically related to a kind of dedicated transmission bolt.
Background technique
Bolt, is widely used in various machinery.During use, by the part that bolt through which floor needs links together, the head of bolt is clamped in part surface, the other end nut check of bolt, but bolt is when urgent or loading torque, need prevent bolt from rotating with the head of professional tool clamping bolt or specialized designs limit structure and realize the urgent of bolt, but for putting in professional tool because arrangement space is too little or arrange the place of position-limit mechanism, just there is the problem cannot tightened because self idle running in bolt.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of dedicated transmission bolt, the head of bolt arranges a carrying cavity, external bearer bar is fixed on described carrying cavity, extended by the working length of external bearer bar by bolt, the processing groove of external bearer boom end is cross cell body, available Hexagonal jacket instrument, also can with a word or cross instrument, conveniently detachable; There is structure simple, feature easy to use.
For achieving the above object, technological scheme of the present invention is as follows:
A kind of dedicated transmission bolt, comprising:
One head, offers a carrying cavity in described head, arrange a circle internal thread in described carrying cavity,
One screw rod be connected with head, described screw rod is provided with outside thread,
One external bearer bar, described external bearer bar is fixed on described head by internal thread, and described external bearer boom end is an operation unit;
Described operation unit is a flat, is provided with processing groove inside flat, and described processing groove is cross cell body.
In a preferred embodiment of the invention, described internal thread is contrary with described externally threaded hand of spiral.
In a preferred embodiment of the invention, described head is hexagonal boss or corner boss.
By technique scheme, the invention has the beneficial effects as follows:
The head of bolt arranges a carrying cavity, external bearer bar is fixed on described carrying cavity, extended by the working length of external bearer bar by bolt, the processing groove of external bearer boom end is cross cell body, available Hexagonal jacket instrument, also can with a word or cross instrument, conveniently detachable; There is structure simple, feature easy to use.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of the plan view of external bearer bar of the present invention.
Embodiment
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
See figures.1.and.2, a kind of dedicated transmission bolt, comprising:
One head 100, offers a carrying cavity 200 in described head 100, arrange a circle internal thread 201 in described carrying cavity 200,
One screw rod 300 be connected with head 100, described screw rod 300 is provided with outside thread 301,
One external bearer bar 400, described external bearer bar 400 is fixed on described head 100 by internal thread 201, and described external bearer bar 400 end is an operation unit 401;
Described operation unit is a flat, is provided with processing groove 402 inside flat, and described processing groove is cross cell body 403.
In a preferred embodiment of the invention, the hand of spiral of described internal thread 201 and described outside thread 301 is contrary.
