Abstract
The utility model relates to a plane volute spiral spring which includes a spring body; the tail end of the outmost ring of the spring body is provided with an outer hook; the outer side of the outmost ring is provided with a fixed ring; the outer hook is revealed on the fixed ring. As the outer hook is revealed, the plane volute spiral spring can be directly mounted during assembly and does not need to be mounted only after the fixed ring is dismounted like the existing plane volute spiral spring; in this way, the plane volute spiral spring is very conveniently arranged; and the outer ring of the spring can not pop out to cause body damage. The plane volute spiral spring is very conveniently maintained and exchanged.
Description
Technical field
The utility model relates to a kind of spring, especially a kind of plane scroll spring.
Background technique
Plane scroll spring claims clockwork spring again, is to form with the steel band coiling, and the one end is fixed, behind the other end action torque, and the distortion of material production bending elasticity.After active force disappeared, the elastic force of spring savings discharged and makes it to be returned to reset condition.
After existing plane scroll spring manufacturing is finished, in being assembled to applied equipment or mechanism before, need put a retainer ring at the outermost of spring, prevent that it from flicking.When assembling, this retainer ring must be taken off, then spring itself is assembled in corresponding apparatus or the mechanism.During specific operation, the direction of spring along its central shaft pushed in the cavity of ccontaining this spring, retainer ring is subjected to stopping of cavity outer wall and can not enters, and finishes assembling thereby break away from spring itself.
Such assembling is by manual mostly, but the time regular meeting misoperation takes place, might come off by retainer ring, and spring does not enter in the cavity fully.At this moment there is not the spring of retainer ring constraint to flick, if some brute spring with high moment of torsion will cause the workman injured.Even if do not cause personnel to injure, also need to assemble again, influence manufacturing efficiency.Moreover, when needing to change spring in maintenance or the maintenance, flick in the time of also will taking measures to prevent to take out spring and hurt sb.'s feelings, equally also very inconvenient.
Summary of the invention
In view of the above-mentioned defective of prior art, technical problem to be solved in the utility model provides a kind of safe plane scroll spring easy to assembly.
For achieving the above object, the utility model provides a kind of plane scroll spring, comprises the spring body, and the outmost turns end of spring body has outer hook, and this outmost turns outside is provided with retainer ring, and this outer hook exposes to this retainer ring.
Preferably, in the above-mentioned plane scroll spring, this retainer ring is positioned at the axial neutral position of spring body outmost turns, and should be at least one by outer hook, is positioned at any side of retainer ring vertically.
More preferably, in the above-mentioned plane scroll spring, this outer hook is two, is positioned at the both sides of retainer ring respectively vertically.
Perhaps, in the above-mentioned plane scroll spring, this retainer ring is positioned at an axial side position of spring body outmost turns, and is somebody's turn to do the opposite side that outer hook is positioned at retainer ring vertically.
Preferably, in the above-mentioned plane scroll spring, this outer hook is positioned at the axial neutral position of spring body outmost turns, and this outer hook is at least one, and this retainer ring is at least one, is positioned at any side of outer hook vertically.
More preferably, in the above-mentioned plane scroll spring, this retainer ring is two, is positioned at the both sides of outer hook respectively vertically.
Preferably, in the above-mentioned plane scroll spring, this outer hook is the end of splicing in this outmost turns; This retainer ring is steel band circle or iron wire loop.
According on the other hand of the present utility model, a kind of plane scroll spring also is provided, comprise the spring body, the outmost turns end of spring body has outer hook, and this outmost turns is fixed on the adjacent with it inner ring, so that outer hook exposes.
Preferably, in the above-mentioned plane scroll spring, this outmost turns is fixed on the adjacent with it inner ring with rivet, and perhaps this outmost turns is weldingly fixed on the adjacent with it inner ring.
The outer hook of plane scroll spring of the present utility model exposes, and can directly install during assembling, needn't retainer ring need be removed and could install as existing plane scroll spring, and therefore very convenient, the spring outer ring can not ejected yet and be caused personal injury.Maintenance and replacing are also very convenient.

Embodiment
The utility model is a kind of plane scroll spring.
Fig. 1 is to an embodiment who Figure 3 shows that this plane scroll spring, and it comprises spring body 1.Outmost turns 2 outsides at this spring body 1 are provided with a retainer ring 3, flick to limit this spring body 1.This retainer ring 3 can be a steel band circle as shown in the figure, or the iron wire loop (not shown).The end of outmost turns 2 has the outer hook 4 that is exposed at these retainer ring 3 outsides.Should outer hook 4 can be the end that splices at spring body 1, also can be with spring body 1 terminal integrally formed.Preferably, the width of this retainer ring 3 is less than the width of spring body 1.
In the present embodiment, this retainer ring 3 is on the outmost turns 2 neutral position vertically, and this outer hook 4 is divided into two, lays respectively at the both sides of this retainer ring 3 vertically.Mode as an alternative, this outer hook 4 also can only comprise one, is in any side of this retainer ring 3 on axially; Perhaps, this retainer ring 3 is in outmost turns 2 side on axially, and outer hook 4 is positioned at the opposite side of outmost turns on axial; Perhaps an outer hook 4 is positioned at axial neutral position, and two retainer rings 3 are in the both sides of outer hook 4 respectively.
In addition, if can will have the outmost turns 2 of outer hook 4 fix, reach the technique effect identical with retainer ring 3, can not use retainer ring 3.For example, the outmost turns 2 that forms this outer hook 4 can use rivet to be fixed on the adjacent with it inner ring (that is second of the ecto-entad circle).Also can adopt welding manner that this outmost turns 2 is fixed on the adjacent with it inner ring.
During assembling, shown in Fig. 4,5, this spring is installed in the housing 5, and housing 5 has mounting groove 6, outer hook 4 is directly inserted in the mounting groove 6 can finish installation, and retainer ring 3 still is retained on the spring body 1, needn't pull down.Adopt this sample loading mode assembling very convenient, spring can not flick in assembly process and cause personal injury.During replacing, also only need original spring is taken out and new the getting final product of packing into together with retainer ring, also very convenient.
Although by embodiment the utility model is explained above, the utility model be not limited to the foregoing description concrete structure and the feature that limits.Those of ordinary skill in the art can make various changes and modifications according to above-mentioned instruction, under the situation that does not break away from the claim protection domain.
