Description
Technical field
The utility model relates to spring technical field more particularly to a kind of double shielding face torque springs.
Background technique
Torque spring is a kind of mechanical storage power structure, and torque spring passes through soft, the biggish elastic material of toughness to material
Distortion or rotation carry out storing power and utilization, make to be launched object with certain mechanical energy, while torque spring is all springs
More complicated one kind of design principle in classification, the variation of pattern is also quite active, thus while designing it is related it is theoretical also the most
It is cumbersome.
Torque spring is durings manufacture, storage, using etc., often by the corrosion of surrounding medium.Since spring exists
It is to play a role when work by elastic force, elastic force can change and loss of function after spring is corroded, and we have proposed one thus
Kind double shielding face torque spring.
Utility model content
Purpose of the utility model is to solve disadvantages existing in the prior art, and a kind of double shielding face proposed
Torque spring.
To achieve the goals above, the utility model adopts the technical scheme that
Design a kind of double shielding face torque spring, including spring body and rubber protecting jacket, the rubber protecting jacket set
It is located on spring body, the surface of the spring body is equipped with corrosion-resistant coating, and the surface of the corrosion-resistant coating is equipped with anti-skid chequer, institute
The inner wall and anti-skid chequer for stating rubber protecting jacket offset, and the surface of the rubber protecting jacket is equipped with wearing layer.
Preferably, the corrosion-resistant coating be epoxy zinc-rich layer, and corrosion-resistant coating with a thickness of 1.5mm.
Preferably, wearing layer includes layer of polyurethane, and the side of layer of polyurethane is bonded with cis-butadiene cement layer, the side of cis-butadiene cement layer
Be bonded with natural glue-line, the side of natural glue-line and the outside of rubber protecting jacket bond, wearing layer with a thickness of 2mm, and gather
The thickness ratio of urethane layer, cis-butadiene cement layer and natural glue-line is 2:4:4.
Preferably, the rubber protecting jacket be butyl rubber protective case, and rubber protecting jacket with a thickness of 3mm.
Preferably, the end diameter of the spring body is greater than the internal diameter of rubber protecting jacket.
The utility model proposes a kind of double shielding face torque spring, beneficial effect is: in the utility model, passing through
Rubber protecting jacket and corrosion-resistant coating protect spring body, while rubber protecting jacket reaches the mesh to corrosion-resistant coating protection
, so that spring body has etch-proof function, avoid the use of corrosion impact torque spring.
Detailed description of the invention
Fig. 1 be the utility model proposes a kind of double shielding face torque spring structural schematic diagram；
Fig. 2 be the utility model proposes a kind of double shielding face torque spring end structure illustration；
Fig. 3 be the utility model proposes a kind of double shielding face torque spring wearing layer structural schematic diagram.
In figure: spring body 1, rubber protecting jacket 2, wearing layer 3, anti-skid chequer 4, corrosion-resistant coating 5, layer of polyurethane 6, cis-butadiene cement
Layer 7, natural glue-line 8.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-3, a kind of double shielding face torque spring, including spring body 1 and rubber protecting jacket 2, rubber protection
Set 2 is set on spring body 1, and the surface of spring body 1 is equipped with corrosion-resistant coating 5, and corrosion-resistant coating 5 is epoxy zinc-rich layer, and
Corrosion-resistant coating 5 with a thickness of 1.5mm, rubber protecting jacket 2 is butyl rubber protective case, and rubber protecting jacket 2 with a thickness of
3mm, the end diameter of spring body 1 are greater than the internal diameter of rubber protecting jacket 2, are set in spring body 1 by rubber protecting jacket 2
On, to be protected to spring body 1, by the corrosion-resistant coating 5 of 1 side of spring body, thus prevent spring body 1 by
Corrosion, and then the use of spring body 1 is influenced, while rubber protecting jacket 2 protects corrosion-resistant coating 5, prevents corrosion-resistant coating 5
It is worn, etch-proof purpose is not achieved, rubber protecting jacket 2 is butyl rubber protective case, and butyl rubber has good bullet
Sexual function, therefore the setting of butyl rubber protective case will not influence the elastic property of spring body 1.
The surface of corrosion-resistant coating 5 is equipped with anti-skid chequer 4, and inner wall and the anti-skid chequer 4 of rubber protecting jacket 2 offset, rubber protecting jacket 2
Surface be equipped with wearing layer 3, wearing layer 3 include layer of polyurethane 6, the side of layer of polyurethane 6 is bonded with cis-butadiene cement layer 7, cis-butadiene cement
The side of layer 7 is bonded with natural glue-line 8, and the side of natural glue-line 8 and the outside of rubber protecting jacket 2 bond, the thickness of wearing layer 3
Thickness ratio for 2mm, and layer of polyurethane 6, cis-butadiene cement layer 7 and natural glue-line 8 is 2:4:4, passes through the anti-of 5 surface of corrosion-resistant coating
Sliding line 4, thus rubber protecting jacket 2 is fixed, it prevents rubber protecting jacket 2 mobile, rubber protecting jacket 2 is carried out by wearing layer 3
Protection, prevents that during use, rubber protecting jacket 2 being ground away, and layer of polyurethane 6 has very strong wear-resisting functions, Neng Gou
When object and layer of polyurethane 6 rub, layer of polyurethane 6 achievees the purpose that protect rubber protecting jacket 2, by cis-butadiene cement layer 7 and naturally
The setting of glue-line 8, since cis-butadiene cement layer 7 and natural glue-line 8 material are soft, so as to make rubber protecting jacket 2 keep elasticity and
Pliability, at the same can achieve the purpose that it is wear-resisting so that the time that rubber protecting jacket 2 uses is longer, so that rubber is protected
The guard time for covering 2 pairs of spring bodies 1 is longer.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
