Abstract
The utility model relates to a pump pin, relating to the field of connecting pieces on spinning equipment, comprising a long-shaft-shaped solid body, wherein any end of the body in the axial direction is provided with a limiting part; the body is at least provided with a first thread section matched with the pump shaft; the body is also provided with a second thread section matched with the pump shaft sleeve. The pump pin is simple in structure, convenient to grab and convenient to disassemble by tools, and has the advantages that a common positioning pin does not have. And the sectional thread on the structure can more firmly fix an object when in use and is not easy to move.
Description
Technical field
This utility model is related to the connector field on spinning equipment, more particularly to a kind of pump pin.
Background technology
Alignment pin acts on much in our productive life；Alignment pin plays the role of positioning：Frame for movement must in closure
Must accurately coordinate and can be only achieved complete connection effect, alignment pin just allows counter structure play the effect being accurately positioned；Positioning
Pin prevents the relative slip between two articles：In the cooperation of pump shaft and pump shaft sleeve, its Main Function is the cunning preventing between the two
Dynamic, it is to avoid to cause connecting staggered, prevent motor overload simultaneously.
Utility model content
, mainly solving the technical problems that providing a kind of pump pin, it is reasonable in design, structure is simple, solves for this utility model
Positioning between pump shaft and pump shaft sleeve and connectivity problem on spinning equipment.
For solving above-mentioned technical problem, the technical scheme that this utility model adopts is to provide a kind of pump pin, including length
The solid body of shaft-like, any one end in the axial direction of described body is provided with limiting section；On the body at least provided with
The first thread segment that pump shaft matches；The second thread segment being matched with pump shaft sleeve is additionally provided with described body.
Preferably, it is provided with transition linkage section between described first thread segment and the second thread segment.
Preferably, the diameter of described transition linkage section is less than the diameter of the first thread segment；Described first thread segment straight
Footpath is not more than the diameter of the second thread segment.
The beneficial effects of the utility model are：There is provided a kind of pump pin, its structure is simple, be easy to crawl and be also convenient for instrument tear open
Unload, there is the superiority that common alignment pin does not possess.And the segmented thread in its structure, can be more firm when using
Fixed object, is not likely to produce movement.
Brief description
Fig. 1 is a kind of structural representation of this utility model pump pin；
Fig. 2 is structural representation in overall structure for the pump pin；
In accompanying drawing, the labelling of each part is as follows：1st, square head cap；2nd, the second thread segment；3rd, the first thread segment；4th, transition connects
Connect section；5th, motor；6th, terminal pad；7th, universal joint；8th, pump shaft；9th, pump shaft sleeve.
Specific embodiment
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model
Can be easier to be readily appreciated by one skilled in the art with feature, thus make apparent clear and definite to protection domain of the present utility model
Define.
Refer to attached Fig. 1 and 2, this utility model embodiment includes：
A kind of pump pin, including the solid body of long shaft-like, as shown in figure 1, the body length selected in the present embodiment exists
60~65mm.Any one end in the axial direction of body is provided with limiting section, limiting section be diameter 13 ~ 15mm, thickness 5 ~ 7mm square
Head cap 1.On body at least provided with the first thread segment 3 matching with pump shaft, body is additionally provided with and matches with pump shaft sleeve
Second thread segment 2.It is provided with transition linkage section 4 between first thread segment 3 and the second thread segment 2.The diameter of transition linkage section 4 is less than
The diameter of the first thread segment 3, the diameter of the first thread segment 3 is not more than the diameter of the second thread segment 2.In the present embodiment, transition is even
Meet a diameter of 6 ~ 7mm of section 4, its axial length is 3mm；A diameter of 8 ~ 9mm of the first thread segment 3, its axial length is 32mm；
A diameter of 12 ~ 13mm of the second thread segment 2, its axial length is 10mm.
As shown in Fig. 2 when pump pin is that pump shaft 8, pump shaft sleeve 9 match, the overall order of connection from top to bottom is successively
Motor 5, terminal pad 6, universal joint 7, pump shaft 8, pump pin, pump shaft sleeve 9.Originally the fixing pump pin of non-threaded is after fracture, easily
It is stuck in pump shaft, causes the phenomenon that discharging is irregular, or produce thickness silk, or repeatedly break end.Now, on the pump pin of insertion axis body
Even if also increasing screw thread so that the fracture of pump pin does not fall out yet, more will not be stuck in pump shaft.
The foregoing is only embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model, every
The equivalent structure made using this utility model description or equivalent flow conversion, or directly or indirectly it is used in other phases
The technical field closed, is all included in the same manner in scope of patent protection of the present utility model.
