Abstract
The invention discloses a fastening bolt for a transmission device. The fastening 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 comprises a transition portion, a thread portion and an impaling portion; and the transition portion, the thread portion and the impaling portion are sequentially connected. External threads are arranged on the thread portion, and 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 bearing cavity is formed in the head portion of the bolt, and the outer bearing rod is fixed to the bearing cavity; through the outer bearing rod, the operation length of the bolt is extended; and the condition that due to too small arrangement space of the bolt, fixation cannot be carried out is avoided. The bolt for the transmission device 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 transmission device 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 transmission device 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, avoid the situation that bolt cannot be fixed because arrangement space is too little, 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 transmission device clamping 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 comprises a transition part, a screw section and puncture portion, described transition part, and screw section and puncture portion three connect successively, and described screw section 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.
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 operation unit is a rectangular block, and rectangular block is provided with processing groove.
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, owing to being provided with external bearer bar, in fact the head of bolt is extended, people are to outside carrier bar twisting operation time, drive the twisting of the bolt be connected with external bearer bar, avoid the problem occurring that bolt cannot be fixed because arrangement space is too little; Once bolt is fixed complete, then external bearer bar departs from bolt; The puncture portion arranging bolt end by quick for bolt access arrangement, can have 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.
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.
With reference to Fig. 1, a kind of transmission device clamping 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 comprises transition part 302, screw section 301 and a puncture portion 303, described transition part 302, and screw section 301 and puncture portion 303 three connect successively, and described screw section 301 is provided with outside thread,
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.
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 operation unit 401 is a rectangular block, rectangular block is provided with processing groove 402.
The head of bolt arranges a carrying cavity, external bearer bar is fixed on described carrying cavity, owing to being provided with external bearer bar, in fact the head of bolt is extended, people are to outside carrier bar twisting operation time, drive the twisting of the bolt be connected with external bearer bar, avoid the problem occurring that bolt cannot be fixed because arrangement space is too little; Once bolt is fixed complete, then external bearer bar departs from bolt; The puncture portion arranging bolt end by quick for bolt access arrangement, can have structure simple, feature easy to use.
More than show and describe basic principle of the present invention and major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
