Abstract
The invention discloses a novel pin shaft fixing bolt. The novel pin shaft fixing bolt comprises a free part (11), a closing part (12) and a spring part (13), wherein the free part (11) is inserted into a pin shaft (2); the closing part (12) is used for preventing the bolt (1) from dropping out of the pin shaft (2); the spring part (13) is used for providing elasticity for the bolt (1); the middle part of the bolt (1) is bent to form the spring part (13); the two ends of the bolt (1) are positioned at the same side of the spring part (13) after being bent, wherein one end is bent inwards to form the closing part (12), and the other end acts as the free part (11). The novel pin shaft fixing bolt disclosed by the invention is normally closed in both a working state and a nonworking state, is automatically closed after being inserted into a pin shaft hole and does not cause drop of the bolt due to human negligence; even when the bolt is scraped by an external force, the opening of the bolt can also be automatically closed after the external force disappears as long as a needle pin is not pulled out, so the pin shaft hardly falls off; an inward angle is formed after the closing part has contact with the free part, so the pin shaft can be inserted quite easily and also hardly drops out.
Description
Technical field
The present invention relates to a kind of latch, be specifically related to a kind of Novel pin shaft and admittedly use latch.
Background technology
Along with the development of science and technology, equipment gradually moves towards maximization, integration, causes construction equipment to continue to increase.There are parts much more very to need bearing pin to connect in the middle of equipment, and it needs dismounting in transition or shipping process, the fixing of such bearing pin, dismantle, the problem of occurring as soon as is installed.If fastening can cause the set-up time long, bad dismounting, if by fixed forms such as current Spring Cards, easily destroyed in severe use environment again, thus, commonly use a kind of installation at present simple, it is difficult to drop, the latch of low cost, use this tradition bearing pin fixed form, as shown in Figure 3, Fig. 3 is tradition bearing pin duty, when off working state safety pin end does not hang on hook, open under elastic force, safety pin pin is after interfering with extraneous part, or artificial carelessness does not makes hook hang up properly, spring can flick, cause the security incident that safety pin pin drops.
Summary of the invention
The problem existed for above-mentioned prior art, the present invention provides a kind of Novel pin shaft admittedly with latch, solves existing Spring Card and touch the security incident problem causing bearing pin to be scurried out that comes off with other parts.
To achieve these goals, the technical solution used in the present invention is: a kind of Novel pin shaft is admittedly with latch, including for inserting freedom portion in bearing pin, limiting the closure that latch comes off from bearing pin and the spring providing elastic force for latch；Bending in the middle part of latch as spring, be positioned at the same side of spring after the two ends bending of latch, wherein one section bends inwards as closure, and the other end is as freedom portion.
Further, the described spring bending number of turns is 2-3 circle.
Further, the end of described closure contacts with freedom portion.
Further, the described freedom portion end is wedge shape.
Further, described latch material is steel material.
Further, after described closure contacts with freedom portion, institute is 30-45 degree in angle.
Compared with prior art: duty of the present invention or off working state are normally closed, automatically close after inserting pin shaft hole, latch will be caused due to human negligence to come off；Even if in the case of by external force scratching, so long as not directly being extracted by needle pin, after external force disappears, latch opening also can close automatically, bearing pin difficult drop-off；Closure forms inside angle with freedom portion after contacting, make to be very easy to during insertion, be not easy again to exit simultaneously.

In figure: 1, latch, 11, freedom portion, 12, closure, 13, spring, 2, bearing pin, 3, workpiece.
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.
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, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of protection of the invention.
As it is shown in figure 1, latch 1 of the present invention is steel wire, including for inserting freedom portion 11 in bearing pin 2, limiting the closure 12 that latch 1 comes off from bearing pin 2 and the spring 13 providing elastic force for latch 1；Bend in the middle part of latch 1 as spring 13, being positioned at the same side of spring 13 after the two ends bending of latch 1, wherein one section bends inwards as closure 12, and the other end is as freedom portion 11, it is 2-3 circle that spring 13 bends the number of turns, the most cost-effective while ensureing to provide enough elastic force.
As shown in Figure 2, during use, it is inserted in the hole of bearing pin 2 by freedom portion 11, elastic force effect by spring 13, closure 12 closes automatically, after Guan Bi, its end contacts with freedom portion 11, and closure 12 contacts with freedom portion 11 and effectively prevent the generation of the unexpected dropping situations of latch 1, it is ensured that workpiece 3 connects the safety used.
Freedom portion 11 end is wedge shape, after closure 12 contacts with freedom portion 11, institute is 30-45 degree in angle, facilitate the installation of latch 1, when freedom portion 11 is inserted in the hole of bearing pin 2, closure 12 touches bearing pin 2, in there being certain angle after contacting with freedom portion 11 due to closure 12, along with deepening continuously of freedom portion 11, closure 12 automatically springs open, portion 12 to be closed fully passes over bearing pin 2, by the elastic force effect by spring 13, closure 12 closes automatically, during dismounting latch 1, the artificial external force giving closure 12 outside, then latch 1 is outwards extracted from the hole of bearing pin 2, the present invention is normally closed contact condition with freedom portion under off working state and closure in working order, security performance is high.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, and without departing from the spirit or essential characteristics of the present invention, it is possible to realize the present invention in other specific forms.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, the scope of the present invention is limited by claims rather than described above, it is intended that all changes fallen in the implication of equivalency and scope of claim included in the present invention.Should not be considered as limiting involved claim by any reference in claim.
The above; it is only presently preferred embodiments of the present invention; not in order to limit the present invention, every any trickle amendment, equivalent and improvement made above example according to the technical spirit of the present invention, within should be included in the protection domain of technical solution of the present invention.
