Abstract
The invention discloses a rotary folding mechanism for a winch handle. The rotary folding mechanism for the winch handle comprises a handle support plate which is provided with a handle support. The handle support is provided with the handle. The handle comprises a handle mandrel which is sleeved with an outer handle shaft sleeve. A compression spring is arranged between the handle mandrel and the outer handle shaft sleeve. The handle mandrel is hinged to the handle support through a hinge pin and a split pin. The handle support is provided with a circular groove. The top end of the outer handle shaft sleeve is clamped in the circular groove when the handle is in a working state. The rotary folding mechanism for the winch handle has the advantages that the handle is fixed in the circular groove of the handle support through the compression spring, so that the handle is not prone to sliding out when working; after the handle stops working, in order to avoid scraping and colliding, the handle can be folded to be in a non-working state as long as the outer handle shaft sleeve is pulled to compress the spring and then rotated by 90 degrees. In this way, the probability of misoperation is lowered, and convenience is brought to personnel safety and production safety.
Description
Technical field
The present invention relates to a kind of capstan winch handle rotary folding mechanism, belong to towing equipment and manufacture field.
Background technology
Common industrial capstan winch handle in the time not using with use time state identical; be open mode; when capstan winch handle does not use so again; easily there is maloperation because touching artificially; cause the accident in personal security, and maloperation also easily easily causes that the location of capstan winch is inaccurate, impact production; bring great economic loss, be badly in need of now a kind of capstan winch handle safety method and change this situation.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point of the prior art, a kind of capstan winch handle rotary folding mechanism is provided, easy to operate, in the time not using, regain handle, reduce maloperation, eliminate safe hidden trouble.
Capstan winch handle rotary folding provided by the invention mechanism, it comprises handle support plate, is provided with handle bearing on handle support plate, on handle bearing, is provided with handle; Described handle comprises handle mandrel, and handle core outer shaft sleeve has handle outer shaft, between handle mandrel and handle outer shaft, is provided with Compress Spring; Described handle mandrel is hinged by bearing pin and spring cotter and handle bearing; On described handle bearing, be provided with circular groove, the top of handle core outer shaft sleeve is stuck in circular groove in the time that handle is in running order.
Optimize, above-mentioned capstan winch handle rotary folding mechanism, the interval of the tail end of its handle mandrel and handle outer shaft arranges the porose back-up ring of using.
Adopted above structure, the present invention has following beneficial effect:
Capstan winch handle rotary folding of the present invention mechanism, owing to having adopted above structure, has following beneficial effect: handle relies on Compress Spring to be fixed in handle bearing circular groove, while work, is difficult for skidding off with handle; After handle end-of-job, for fear of scratching, when handle is retracted into off working state, only need pull half-twist after handle outer shaft Compress Spring, reduce like this possibility of maloperation, bring facility to personal security and production safety.
Accompanying drawing explanation
In order to be illustrated more clearly in the present invention, below will be to by reference to the accompanying drawings embodiment being briefly described.
Fig. 1 is the structural representation of capstan winch handle rotary folding of the present invention mechanism;
Fig. 2 is the left view of Fig. 1.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
Referring to accompanying drawing 1,2, capstan winch handle rotary folding of the present invention mechanism, it comprises handle support plate 1, is provided with handle bearing 3 on handle support plate 1, is provided with handle 2 on handle bearing 3; Described handle 2 comprises handle mandrel 21, and handle mandrel 21 overcoats have handle outer shaft 22, between handle mandrel 21 and handle outer shaft 22, is provided with Compress Spring 7; Described handle mandrel 21 is hinged with handle bearing 3 by bearing pin 4 and spring cotter 6; On described handle bearing 3, be provided with circular groove 31, the top of handle outer shaft 22 is stuck in circular groove 31 in the time that handle 2 is in running order.The interval of the tail end of handle mandrel 21 and handle outer shaft 22 arranges porose with back-up ring 5.Handle of the present invention relies on Compress Spring to be fixed in handle bearing circular groove, while work, is difficult for skidding off with handle; After handle end-of-job, for fear of scratching, when handle is retracted into off working state, only need pull half-twist after handle outer shaft Compress Spring, reduce like this possibility of maloperation, bring facility to personal security and production safety.
Finally it should be noted that: above embodiment only, in order to technical scheme of the present invention to be described, is not intended to limit; Although the present invention is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
