Abstract
The utility model discloses a kind of swinging screen, the technical solution of the utility model is, it includes retaining spring, puller bolt body, is set with a metal extension spring in retaining spring, the both ends of metal extension spring are fixed on pre-embedded bolt；The end of puller bolt body is hemispherical, and the concave pad matched somebody with somebody with puller bolt body phase is shaped as：Concave spherical with hemisphere with diameter.The beneficial effects of the utility model are：Due to the tension linear of metal spring and antifatigue better than India-rubber spring.By improving, the life-span of swinging screen composite spring is improved, and holds out against rational in infrastructure, stress more science, and service life is longer.
Description
Technical field
Swinging screen is the utility model is related to, particularly a kind of Novel remote vibrating screen.
Background technology
The retaining spring of swinging screen is originally that gum part adds pre-embedded bolt, because the hunting frequency of swinging screen is high, swings
Amplitude is big；The stretching frequency and stretch range of retaining spring are all big, cause rubber parts meeting fatigue and aging, it is easy to be broken, make
It is shorter with the life-span, it is unfavorable for the performance of the production efficiency of swinging screen；The structure of the puller bolt of present swinging screen is complex,
It generally requires and a centre bore is provided with the body of bolt, after recycling a pin to squeeze into centre bore, completes puller bolt
It is fixed, such connected mode, cause the complicated and processing cost of puller bolt higher；And the body of bolt is by upper and lower exciting
The influence of power, pin is easy to break, influences the service life of puller bolt.
The content of the invention
The purpose of this utility model is a kind of swinging screen rational in infrastructure, using effect is good of design.
The technical solution of the utility model is a kind of swinging screen, and it includes retaining spring, puller bolt body, and its feature exists
In：A metal extension spring is set with retaining spring, the both ends of metal extension spring are fixed on pre-embedded bolt；The end of puller bolt body
To be hemispherical, the concave pad matched somebody with somebody with puller bolt body phase is shaped as：Concave spherical with hemisphere with diameter.
The beneficial effects of the utility model are：Due to the tension linear of metal spring and antifatigue better than India-rubber spring.It is logical
Improvement is crossed, the life-span of swinging screen composite spring is improved, and holds out against rational in infrastructure, stress more science, and service life is longer.
Brief description of the drawings
Fig. 1 is the structural representation of retaining spring described in the utility model；
Fig. 2 is the structural representation of puller bolt body described in the utility model.
Embodiment
Embodiment is described in detail with reference to the figures above：
A kind of swinging screen special purpose spring, it includes retaining spring 1, and it includes puller bolt body, and one is set with retaining spring
Individual metal extension spring 2, the both ends of metal extension spring are fixed on pre-embedded bolt 3；The end of puller bolt body 11 is hemispherical 22, with top
The concave pad 33 that the tight body of bolt matches is shaped as：Concave spherical with hemisphere with diameter
The internal sleeve of retaining spring of the present utility model, i.e. India-rubber spring is equipped with an extension spring, and the both ends of extension spring are fixed on pre-
Bury on bolt, be easy to the installation of whole special purpose spring；Puller bolt screw thread boom end in the present embodiment is raised sphere, concave pad
For the concave spherical with raised sphere with diameter.No matter bolt is vertically to hold out against or holding out against with certain angle, can be ensured
Hold out against effect.
Above-described embodiment is only intended to clearly illustrate example, and is not the restriction to embodiment.For institute
For the those of ordinary skill in category field, other various forms of changes or change can also be made on the basis of the above description
It is dynamic.There is no necessity and possibility to exhaust all the enbodiments, and the obvious change or change thus extended out
Within the dynamic protection domain created still in the utility model.
