Abstract
It the utility model is related to a kind of spring.Including spring body and position limiting structure, the spring sheet is made up of at least three bung flange layers, the bung flange layer is provided with the through hole vertical with each bung flange layer, the hole heart of each through hole on each bung flange layer is on the same line, the position limiting structure includes rope and block body, the rope passes through through hole, and opposing through-bores rope can slide up and down, and it is fixed with block body on the rope between adjacent turns layer, length between adjacent block body is not more than the elastic maximum effective length that adjacent turns layer can reach, and the aperture of the through hole is less than block body maximum effective diameter.The spring structure sets advantages of simple, the generation for effectively preventing spring from leading to not reset beyond maximum effective length itself because of stress stretching, extends the service life of spring, while making is simple, and production efficiency is high, and good practical effect is easy to spread.
Description
Technical field
It the utility model is related to a kind of elastic component, and in particular to a kind of spring.
Background technology
Spring is to produce power using the deformation of itself or store the machine components of energy, and its major function has control machinery fortune
Dynamic, absorption vibration and impact energy, storage and output energy are as power and as load-sensing unit etc..Spring is widely used,
There is also deficiency, such as spring are excessive by pulling force, beyond the elastic range of itself, spring permanent deformation, nothing will result in
Method is recovered.Existing Chinese patent discloses a clock spring, the applying date：2014.12.03 application number：201420410692.2
The spring avoids spring because of stress excessive the problem of can not recovering, but this is complicated, makes difficult, and production cost is high.
Utility model content
For the deficiency in background technology, the utility model provides a kind of spring, and overcomes disadvantages described above.
Technical scheme is used by the utility model：A kind of spring, including spring body and position limiting structure, the bullet
Spring sheet is made up of at least three bung flange layers, and the bung flange layer is provided with the through hole vertical with each bung flange layer, on each bung flange layer
Each through hole the hole heart on the same line, the position limiting structure includes rope and block body, and the rope passes through through hole, and relatively
Through hole rope can be slided up and down, and block body is fixed with the rope between adjacent turns layer, and the length between adjacent block body is little
In the elastic maximum effective length that adjacent turns layer can reach, the aperture of the through hole is less than block body maximum effective diameter.
The tapered structure setting of block body.
Fluorescence material is coated with the outer surface of the block body.
The endurance of the rope is more than the gravity that can bear under spring body maximum effective length.
The position limiting structure is at least provided with two, and equidistant circle distribution.
The beneficial effects of the utility model are：Due to taking above-mentioned technical proposal, existing spring stress mistake is effectively improved
The problem of dividing stretching and causing spring permanent distortion, the spring structure sets advantages of simple, effectively prevents spring from being stretched because of stress
The generation for leading to not reset beyond maximum effective length itself, extends the service life of spring, while makes simple, production effect
Rate is high, and good practical effect is easy to spread.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is spiral layers 2 and the local job's state cut away view of block body 3 in Fig. 1.
1, spring body in figure；2nd, bung flange layer；3rd, through hole；4th, position limiting structure；5th, rope；6th, block body.
Embodiment
The utility model embodiment is described further below in conjunction with the accompanying drawings.
As shown in Figure 1 with Figure 2, a kind of spring, including spring body 1 and position limiting structure 4, the spring body 1 is by extremely
Few three bung flange layers 2 form, and the bung flange layer 2 is provided with the through hole 3 vertical with each bung flange layer 2, each on each bung flange layer 2
On the same line, the position limiting structure 4 includes rope 5 and block body 6 to the hole heart of through hole 3, and the rope 5 preferably selects steel wire
Rope, there is certain pliability and endurance is strong, and the rope 5 passes through through hole 3, and the rope 5 of opposing through-bores 3 can slide up and down, and
It is fixed with block body 6 on rope 5 between adjacent turns layer 2, the length between adjacent block body 6 is not more than 2 energy of adjacent turns layer
The elastic maximum effective length reached, block body 6 equidistantly distribute, and the aperture of the through hole 3 is less than the maximum effective diameter of block body 6.
The 6 tapered structure setting of block body, when the stress of rope 5 acts on, pyramidal structure, which is set, is easy to being stuck in for block body 6
In corresponding through hole 3, guide effect is played, using effect is good.
Fluorescence material is coated with the outer surface of the block body 6, it is more eye-catching, it is easy to look for.
The endurance of the rope 5 is more than the gravity that can bear under 1 maximum effective length of spring body, protects spring sheet
Body 1 is indeformable.
The position limiting structure 4 is at least provided with two, and equidistant circle distribution.
The stress of spring body 1 stretches, and when stress exceedes the scope that spring body 1 can bear, position limiting structure 4 plays pair
The protective effect of spring body 1, it can specifically be reached no more than adjacent turns layer 2 by the length between adjacent block body 6
The maximum effective length of elasticity, so when the length of spring body 1 is also not reaching to the limit, the stress of rope 5, on rope 5
Block body 6 blocks the stretching of bung flange layer 2, and whole power is born by rope 5, prevents spring body 1 from exceeding effective range, would not also make
Into the excessive situation for causing permanent deformation of the stress of spring body 1, extend spring service life.
The problem of the utility model effectively improves the too stretching of existing spring stress and causes spring permanent distortion, the bullet
Spring structure sets advantages of simple, the hair for effectively preventing spring from leading to not reset beyond maximum effective length itself because of stress stretching
It is raw, extend the service life of spring, while simple, production efficiency height is made, good practical effect is easy to spread.
Every technical staff's notice：Although the utility model describes according to above-mentioned embodiment, this
The invention thought of utility model is not limited to that utility model, any repacking with inventive concept, will all include this specially
In sharp scope of patent protection.
