Abstract
The utility model discloses a kind of double tension springs, solve the problems, such as that installs fixture easily ejects double tension springs.It includes spring body, drag hook and the link arm being connected between spring body, centre bore is formed in the spring body, the drag hook is connect with spring body one end, the drag hook includes bending section and butting section, and the butting section is connected at the aperture between bending section and one end of spring body and passing through centre bore one end.Butting section is at the aperture of spring body centre bore one end, can resist the pressure that external devices penetrate spring body centre bore and apply to drag hook, it is ensured that whole using effect, protection external devices are not damaged.
Description
Technical field
The utility model relates to elastic component field, especially a kind of double tension springs.
Background technique
Tension spring is subject to the helical spring of axial tension, is worked using the screen resilience (pulling force) after stretching, to control machine
Movement, storage or saving energy, size of measuring force of part etc., are widely used in the fields such as mechanical device, electrical equipment.Double tension springs are
A kind of modified product of tension spring, such as patent No.: 201520576110.2, patent name: the Chinese patent of spring, it is practical open
A kind of double tension springs, damping effect poor the problems such as low for solving structural strength.However, this double tension springs are usually mounted to pacify
In clamps or other external devices, by taking installs fixture as an example, the column of installs fixture penetrates in spring body from link arm side, when
When by active force toward link arm direction, column is easy ejector spring body, withstands on that drag hook is interior or the drag hook that is staggered directly is pierced by, and leads
It causes double tension springs that can not play a role, or even column is made to crumble.
Summary of the invention
The purpose of this utility model: in order to overcome the drawbacks of the prior art, the utility model provides a kind of double tension springs, solution
Certainly installs fixture easily ejects the problem of double tension springs.
The technical solution of the utility model includes: including spring body, drag hook and the link arm being connected between spring body, in the spring body
Centre bore is formed, the drag hook is connect with spring body one end, and the drag hook includes bending section and butting section, and the butting section connects
It is connected between bending section and one end of spring body and passes through at the aperture of centre bore one end.
By adopting the above technical scheme, butting section is at the aperture of spring body centre bore one end, can be resisted external devices and be worn
The pressure for entering spring body centre bore and drag hook being applied, it is ensured that whole using effect, protection external devices are not damaged.
The further setting of the utility model: butting section is extended to from the side periphery of spring body through the center in centre bore aperture
On the other side periphery of spring body.
Using above-mentioned further setting, the butting section that is staggered inside penetrating into center hole is prevented.
The further setting of the utility model: the outer end of bending section is also extended with epitaxy part, and the epitaxy part is set to
Butting section side and pass through centre bore one end aperture at.
Further it is arranged using above-mentioned, epitaxy part, which can equally play, to be resisted external devices and penetrate spring body center pore pressure force
Effect, increase aperture can rest surface, further enhance abutment action.
The further setting again of the utility model: link arm include there are two straight line portion and curved portion, it is whole in " ("
Shape, the curved portion are set between two straight line portions, and two straight line portions are separately connected corresponding spring body.
Using above-mentioned setting further again, bottom is smooth, transitional good.
Detailed description of the invention
Fig. 1 is the main view of the utility model specific embodiment；
Fig. 2 is the left view of the utility model specific embodiment；
Fig. 3 is the perspective view of the utility model specific embodiment | (omitting right spring body and link arm)；
Wherein, spring body 1, drag hook 2, link arm 3, left spring body 11, right spring body 12, centre bore 13, bending section 21, butting section 22,
Epitaxy part 23, straight line portion 31, curved portion 32.
Specific embodiment
A kind of double tension springs as shown in FIG. 1 to FIG. 3, include spring body 1, drag hook 2 and the link arm 3 being connected between spring body 1,
Centre bore 13 is formed in spring body 1, for penetrating the column of external devices, drag hook 2 is connect with 1 one end of spring body, and 1 other end of spring body connects
Arm 3 in succession.Drag hook 2 includes bending section 21 and butting section 22, butting section 22 be connected to bending section 21 and spring body 1 one end it
Between and pass through 13 one end of centre bore aperture at.Butting section 22 is from the side periphery of spring body 1 through the center in 13 aperture of centre bore
It extends on the other side periphery of spring body 1, is equivalent to periphery cross center hole 13 aperture of the butting section 22 from 13 aperture of centre bore
On the periphery of the 13 aperture other side of center to center hole.Center of the butting section 22 through 13 aperture of centre bore is above 1 one end of spring body
Bending section 21 is connected, bending section 21 is in arc-shaped, is used for hanging object.Spring body 1 includes left spring body 11 and right spring body 12, left spring
Body 11 and right spring body 12 are arranged in parallel, and there are two being separately positioned in left spring body 11 and right spring body 12, link arm 3 connects the tool of drag hook 2
Between left spring body 11 and right spring body 12.When penetrating the column of external devices in left spring body 11 and right spring body 12, butting section is supported
On one end of column, column is prevented to be pierced by centre bore 13.
The outer end of bending section 21 is also extended with epitaxy part 23, and epitaxy part 23 is set to 22 side of butting section and passes through centre bore
At the aperture of 13 one end.Epitaxy part 23 increase aperture can rest surface, it is applicable vertical in 13 inside and outside device of penetrating into center hole
The lesser situation of column.In addition, there are gap between epitaxy part 23 and butting section 22, the two is not directly contacted with, for being inserted in suspension
Object in bending section 21.
Link arm 3 includes there are two straight line portion 31 and curved portion 32, and whole is in that " (" shape, curved portion 32 are set to two directly
Between line portion 31, two straight line portions 31 are separately connected corresponding left spring body 11 or right spring body 12.
