Abstract
The invention discloses an adjusting pull pin. The adjusting pull pin comprises a pull pin sleeve and a pull pin shaft, wherein the pull pin shaft is sleeved with the pull pin sleeve and a spring, a pull pin nut is arranged on the pull pin sleeve, a connecting block is connected to the top end of the pull pin shaft through a chain link and installed on a rotary handle, and the rotary handle is installed on a fixed support. The pull pin structure can be placed in a narrow space, and axial movement of the pull pin shaft is achieved based on the lever principle, so that convenience is achieved, and efforts are saved.
Description
Technical field
The present invention is used for fitness equipments manufacturing technology field, provides a kind of adjustment and draws pin.
Background technique
Usually when space is enough, drawing pin only need directly pull at draws pin handle can realize drawing moving axially of bearing pin, thus reach the regulatory function of mechanism, when drawing pin need be arranged in a narrow space, then cannot conveniently realize drawing moving axially of bearing pin.
Summary of the invention
The object of the invention is to overcome above deficiency, provide a kind of structure simple, easy to use and labour-saving regulate draw pin.
Object of the present invention is achieved through the following technical solutions: a kind of adjustment draws pin, comprise and draw guide and draw bearing pin, guide inner sleeve is drawn to draw bearing pin, cover on bearing pin is drawn to have spring, draw guide to be provided with and draw pin nut, draw bearing pin top to be connected with contiguous block by chain link, contiguous block is installed on turning handle, and turning handle is installed on fixed support.
The present invention compared with prior art has the following advantages: the present invention be can be placed in narrow space draw pin structure, utilize lever principle to realize drawing moving axially of bearing pin, convenient and laborsaving.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of A-A in Fig. 1;
Number in the figure: 1-draws that guide, 2-spring, 3-draw bearing pin, 4-draws pin nut, 5-chain link, 6-contiguous block, 7-turning handle, 8-fixed support.
embodiment:
For making the object of the embodiment of the present invention, technological scheme and advantage clearly, be clearly and completely described to the technological scheme in the embodiment of the present invention below, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.The element described in one embodiment of the invention and feature can combine with the element shown in one or more other mode of execution and feature.It should be noted that for purposes of clarity, in explanation, eliminate expression and the description of unrelated to the invention, parts known to persons of ordinary skill in the art and process.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not paying creative work, belongs to the scope of protection of the invention.
A kind of mode of execution drawing pin is regulated as Fig. 1 and Fig. 2 shows the present invention, comprise and draw guide 1 and draw bearing pin 3, guide 1 inner sleeve is drawn to draw bearing pin 3, cover on bearing pin 3 is drawn to have spring 2, draw guide 1 to be provided with and draw pin nut 4, draw bearing pin 3 top to be connected with contiguous block 6 by chain link 5, contiguous block 6 is installed on turning handle 7, and turning handle 7 is installed on fixed support 8.
During use, rotate counterclockwise turning handle 7, drive contiguous block 6 to be rotated counterclockwise, pull bearing pin 3 by chain link 5, realize drawing moving axially of bearing pin, unclamp turning handle 7, can be resetted by spring 2 elastic force, thus realize the regulatory function of mechanism.
Although last it is noted that described the present invention and advantage thereof in detail above, be to be understood that and can carry out various change when not exceeding the spirit and scope of the present invention limited by appended claim, substituting and converting.And scope of the present invention is not limited only to the specific embodiment of process, equipment, means, method and step described by specification.One of ordinary skilled in the art will readily appreciate that from disclosure of the present invention, can use perform the function substantially identical with corresponding embodiment described herein or obtain and its substantially identical result, existing and that will be developed in the future process, equipment, means, method or step according to the present invention.Therefore, appended claim is intended to comprise such process, equipment, means, method or step in their scope.
