Description
Technical field
The invention belongs to bolt field.
Background technology
With the fast development of China's economy, fastener is not only advanced in electronic product, machinery, computer, mobile phone, automobile etc.
Field is widely applied.Screw is a kind of conventional connector, because the vibrations of plant equipment cause the toner screw to influence
Equipment normal work, has a strong impact on the safety and stability of equipment.
On 2 24th, 1999, China Southwest Airline Company TY154M/B-2622 aircrafts were performing Chengdu to Wenzhou
During SZ4509 flight tasks, had an accident with hitting in Wenzhou Area, the comminuted disintegration of aircraft, 61 people are all wrecked on machine, investigation card
It is real, it is that nut is screwed out in flight course due to aircraft, connecting bolt comes off, causes the disabled of aircraft pitch passage and lose
Thing.Therefore, it is badly in need of a kind of bolt with locking anti-back function, to increase the safety and stability of equipment.
The content of the invention
It is an object of the invention to provide a kind of fastening bolt with anti-back function.
In order to achieve the above object, base case of the invention provides a kind of Anti-withdrawing bolt, including screw rod and is connected to
Nut on screw rod, also including check lock lever, the check lock lever is threaded rod, is equipped with the nut and screw rod and check lock lever phase
The screwed hole of matching, is provided with cavity of the aperture more than the aperture of screwed hole in the screw rod, be provided with the cavity equipped with A glue
First air bag and the second air bag equipped with B glue, the bottom of the check lock lever are provided with for puncturing the first air bag and the second air bag
Tartar, is provided with dumping mouthful in the screw rod.
The principle of this base case is：When fixing equipment is wanted, first, tighten screw rod and be fixed, then, rotation lock
Tight bar, check lock lever is moved down.As tartar and when the first air bag and the second balloon contacts, tartar is by the first air bag and the second air bag
Puncture so that the mixing of B glue in the A glue and the second air bag in the first air bag, be rotated further check lock lever, so as to by mixed A
Glue and B glue are extruded from dumping mouthful, so that screw rod is adhesive in equipment, form dual fixation.
The beneficial effect of this base case is：The aperture of cavity is set must be slightly larger than screwed hole, on the one hand can be more
It is convenient that air bag is installed, on the other hand also cause that mixed A glue and B glue there are enough spaces to be discharged from dumping mouthful.When to anti-
Pine requires equipment high, then tighten check lock lever, it is ensured that the safety and stability of equipment, to locking less demanding equipment,
Can not then tighten or remove check lock lever.Compared with traditional bolt, this programme can form dual fixation, and anti-loosing effect is good.
Scheme two：Scheme is preferred based on this, and also including pricker, the pricker is fixed on tartar.The setting of pricker,
Can ensure that the first air bag and the second air bag are punctured, simultaneously as check lock lever is downward spiral movement, therefore, rotation lock bar
Pricker can be driven to rotate, also act the effect for well mixing A glue and B glue, it is ensured that the final viscous force of glue.
Scheme three：Scheme is preferred based on this, and the lower end of the screw rod is provided with conehead.The setting of conehead, may be such that spiral shell
Bolt has the function of screw, using more convenient.
Scheme four：Scheme is preferred based on this, and the top of the check lock lever is provided with cross recess or plum blossom groove.Cross recess or
The setting of plum blossom groove, can more convenient rotation lock bar.
Brief description of the drawings
Fig. 1 is the structural representation of embodiment of the present invention Anti-withdrawing bolt.
Fig. 2 is the top view of embodiment of the present invention Anti-withdrawing bolt.
Fig. 3 is the structural representation of embodiment of the present invention Anti-withdrawing bolt.
Specific embodiment
Below by specific embodiment, the present invention is further detailed explanation：
Reference in Figure of description includes：Screw rod 10, dumping mouthful 101, conehead 20, check lock lever 30, cross recess 301, thorn
First 302, pricker 303, the first air bag 41, the second air bag 42.
As shown in Figure 1 and Figure 2, Anti-withdrawing bolt, the main spiral shell for including check lock lever 30, screw rod 10 and being connected on screw rod 10
Cap.The lower end of screw rod 10 is provided with conehead 20, may be such that bolt has the function of screw.Screwed hole is provided with screw rod 10 and nut,
Check lock lever 30 is threaded rod, and threaded rod coordinates with the mutual screw thread of screwed hole.The top of check lock lever 30 is provided with cross recess 301, can be square
Just by screwdriver rotation lock bar 30, it is of course also possible to according to circumstances be set to plum blossom groove.
As shown in figure 3, being additionally provided with cavity in screw rod 10, the bottom of cavity is respectively arranged with the first air bag 41 and the second air bag
42, built with A glue, the second air bag 42 is built with B glue for the first air bag 41.Dumping mouthful 101, dumping mouthful 101 are additionally provided with screw rod 10
Connected with cavity.The lower end of check lock lever 30 is provided with tartar 302, and the tartar 302 is tapered, is mainly used in puncturing A glue and B glue, makes
Obtain A glue and the mixing of B glue.Meanwhile, multiple prickers 303 are also provided with tartar 302, pricker 303 is obliquely installed.On the one hand, acupuncture
Can ensure that the first air bag 41 and the second air bag 42 are punctured, on the other hand, because check lock lever 30 is downward spiral movement, therefore,
Rotation lock bar 30 can drive pricker 303 to rotate, and also act the effect of the good mixing of A glue and B glue, it is ensured that glue it is final
Viscous force.The design of cavity needs to essentially consist in：The aperture of cavity can't cause cavity slightly larger than the aperture of screwed hole
Aperture much larger than screwed hole aperture, after need to ensuring that tartar 302 punctures the first air bag 41 and the second air bag 42, can will be mixed
A glue and B glue are extruded from dumping mouthful 101.
When specifically used, when fixing equipment is wanted, first, tighten screw rod 10 and be fixed, then, rotation lock bar 30,
Check lock lever 30 is moved down.When tartar 302 contacts with the first air bag 41 and the second air bag 42, tartar 302 is by the first air bag 41
Punctured with the second air bag 42 so that the B glue mixing in the A glue and the second air bag 42 in the first air bag 41, be rotated further check lock lever
30, so as to mixed A glue and B glue be extruded from dumping mouthful 101, so that screw rod 10 is adhesive in equipment, form double
Fix again.
By the aperture of cavity set must slightly larger than screwed hole, on the one hand can air bag more convenient to install, on the other hand also make
Obtaining mixed A glue and B glue has enough spaces to be discharged from dumping mouthful 101.When equipment high is required to locking, then will locking
Bar 30 is tightened, it is ensured that the safety and stability of equipment, to locking less demanding equipment, then can not tighten or remove locking
Bar 30.Compared with traditional bolt, this programme can form dual fixation, and anti-loosing effect is good.
Above-described is only embodiments of the invention, and the general knowledge such as known concrete structure and characteristic is not made herein in scheme
Excessive description.It should be pointed out that for a person skilled in the art, on the premise of structure of the present invention is not departed from, can be with
Some deformations and improvement are made, these should also be considered as protection scope of the present invention, these are implemented all without the influence present invention
Effect and practical applicability.This application claims protection domain should be defined by the content of its claim, in specification
Specific embodiment etc. records the content that can be used for explaining claim.
