Abstract
The invention discloses a release preventing bolt. The release preventing bolt comprises a bolt, wherein a locking pin is inserted in a locking hole longitudinally penetrating through the bolt; and a release preventing ring and the locking pin are in fit locking. The bolt is a cylinder; a base is arranged at one end of the bolt; a taper port is formed in the other end of the bolt; and the locking hole longitudinally penetrating through the bolt and fitting the locking pin is formed in a pin body near the taper port. The release preventing bolt achieves an effect of preventing the locking pin from being released through the fit locking between the release preventing ring and the locking pin, can be recycled for many times, and is release preventing bolt with safety, convenience, economy and reliability.
Description
Technical field
The present invention relates to a kind of fastening means, especially a kind of anticreep latch.
Background technique
In installing engineering, mostly pinned connection is adopted between rod member, pinned connection has easily peace and tears open and the advantage of not fragile link, and what the anticreep measure of bearing pin was generally taked is insertion opening pin after the boring of its tail end, or is equipped with fastening nut etc. after bearing pin afterbody is processed into silk mouth.
But, adopt cotter pin mode, because the shank of cotter pin is made up of two blocks of semicircle materials, pulled open through after bearing pin, made it difficult drop-off, therefore when removing, cotter pin is not easily pulled down, particularly (be greater than 10mm) when the diameter of cotter pin is larger, be difficult to pull open cotter pin and reduce backed off after random directly by hand, while this cotter pin single use often.
Be equipped with the mode of fastening nut after adopting bearing pin afterbody processed filament mouth, there is the problems such as the easy corrosion of bearing pin silk mouth, breakage, be therefore also difficult to turnover and use.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of anticreep latch, has to be convenient to peace and to tear open and reusable advantage.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of anticreep latch, comprises latch, and stop pin inserts on latch and longitudinally runs through in the lockhole of latch, and anti-decylization and stop pin cooperatively interact and lock.
Latch is cylindrical body, and latch one end is provided with base, and the latch the other end is provided with cone mouth, and the shank of contiguous cone mouth has the lockhole coordinated with stop pin longitudinally running through latch.
One end of stop pin is provided with ring, and the other end of stop pin is taper, has anti-decylization in ring inner sleeve, and the external diameter of anti-decylization slightly larger than the external diameter of latch, but is less than the length of stop pin; The length of stop pin is slightly larger than the diameter of latch; Anti-decylization is high resilience and has the anti-decylization that certain shear resistance material is made.
Anti-decylization is the anti-decylization that spring steel is made.
Anticreep latch provided by the invention, is cooperatively interacted by anti-decylization and stop pin and locks, play the effect preventing stop pin from coming off, reusable several, is a kind of safety, convenient, economic locking pin reliably.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is plan view of the present invention;
Fig. 2 is right elevation of the present invention;
Fig. 3 is the present invention's anticreep annular strain view when using;
Fig. 4 is fundamental diagram of the present invention.
Embodiment
As depicted in figs. 1 and 2, the present invention includes latch 1, stop pin 2 inserts on latch 1 and longitudinally runs through in the lockhole 4 of latch 1, and anti-decylization 3 cooperatively interacts with stop pin 2 and locks.
Latch 1 is cylindrical body, and latch 1 one end is provided with base 1-1, and latch 1 the other end is provided with cone mouth 1-2, and the shank of contiguous cone mouth 1-2 has the lockhole 4 coordinated with stop pin 2 longitudinally running through latch 1.
One end of stop pin 2 is provided with ring 2-1, and the other end of stop pin 2 is taper, has anti-decylization 3 in ring 2-1 inner sleeve, and the external diameter of anti-decylization 3 slightly larger than the external diameter of latch 1, but is less than the length of stop pin 2; The length of stop pin 2 is slightly larger than the diameter of latch 1; Anti-decylization 3 is high resilience and has the anti-decylization that certain shear resistance material is made.
The anti-decylization that anti-decylization 3 is made for spring steel.When anti-decylization 3 becomes oval under External Force Acting (adult holds power), now become oval anti-decylization 3 major axis to be greater than the length (as shown in Figure 3) of stop pin 2, anti-decylization 3 can be walked around the plunger of stop pin 2 and be positioned at opposite side thus.When after the external force that comes loose, anti-decylization 3 recovers original toroidal, locked between latch 1 and stop pin 2, thus plays the effect preventing stop pin 2 from coming off.
As shown in Figure 4, working principle of the present invention is as follows:
After stop pin 2 being penetrated the lockhole 4 of latch 1, rotate anti-decylization 3 and make it walk around the cone mouth 1-2 of latch 1, then grasp anti-decylization 3 and make it be out of shape, then walk around the plunger of stop pin 2, after loosing one's grip.
Claims (4)
