Abstract
The utility model discloses a kind of Spring balancer, including body, the body exterior, which is arranged with housing, the main shaft of the body, is connected with cone pulley, and the cone pulley includes upper surface, lower surface and the conical surface, and the upper surface is provided with through hole.The utility model uses the Spring balancer of said structure, increases the contact area of cone pulley and safety pin, it is ensured that cone pulley improves the security context of operator by safety pin locking.
Description
Technical field
The utility model is related to machinery manufacturing technology field, more particularly to a kind of Spring balancer.
Background technology
Spring balancer is to reach a power using the pulling force of wind spring inside Spring balancer and the weight of suspended matter product
Balance, the power of operator's very little can be allowed just can easily to allow suspended item to walk up and down or stop in Spring balancer
At an arbitrary position.As shown in figure 1, when needing to change load, the safety pin on balancer casing is sunk down into cone pulley in housing
Groove in, locking cone pulley.
When safety pin is sunk on cone pulley in top surface groove, influenceed by wind spring elastic force, safety pin is contacted with cone pulley
Part be also easy to produce deformation, it is impossible to locking cone pulley.Safety pin is relatively moved with cone pulley, and the steel wire rope on cone pulley is quickly drawn back
In balancer, steel wire rope is easy to lash neighbouring operator and equipment, causes to injure operator, damages machine and set
It is standby.
Utility model content
The purpose of this utility model is to provide a kind of Spring balancer, increases the contact area of cone pulley and safety pin, protects
Cone pulley is demonstrate,proved by safety pin locking, the security context of operator is improved.
To achieve the above object, the utility model provides a kind of Spring balancer, including body, the body exterior set
Provided with housing, cone pulley is connected with the main shaft of the body, the cone pulley includes upper surface, lower surface and the conical surface, the upper surface
It is provided with through hole.
It is preferred that, the safe pin connection of the through hole and the body.
It is preferred that, the conical surface is provided with the wind spring being connected with the main shaft.
It is preferred that, the housing is provided with worm screw, and the worm screw is connected with the wind spring.
It is preferred that, the drawstring that bottom connecting shackle is provided with grooving, the grooving is provided with the conical surface.
Therefore, the utility model uses the Spring balancer of said structure, increases the contact area of cone pulley and safety pin,
Ensure that cone pulley, by safety pin locking, improves the security context of operator.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.

Embodiment
Embodiment of the present utility model is described further below in conjunction with the accompanying drawings.
Fig. 3 is the schematic diagram of the utility model cone pulley embodiment, as shown in figure 3, a kind of Spring balancer, including body
101, be cased with housing 102, the main shaft 107 of body 101 being connected with cone pulley 103 outside body 101, cone pulley 103 include the conical surface 104, on
Through hole 201 is provided with end face 1051, lower surface 1052, upper surface 1051.Through hole 201 connects safety pin 202.The conical surface 104 is provided with
The wind spring 111 being connected with main shaft.Housing 102 is provided with worm screw 108, and worm screw 108 is connected with wind spring 111.The upper surface of cone pulley 103
1051st, lower surface 1052 is by bearing and main shaft 107, and main shaft 107 is connected with the worm screw 108 of housing 102.The conical surface 104 has rope
Drawstring is provided with groove 109, grooving 109, drawstring bottom is provided with suspension hook 110.
Below by the specific course of work of the present embodiment, the technical solution of the utility model is done and further retouched in detail
State.
During using Spring balancer, weight is hung by the suspension hook 110 of drawstring bottom, the deformation of wind spring 111 is driven, passes through rotation
Turn the pulling force of wind spring 111, stored energy in the regulation Spring balancer of worm screw 108.Drawstring in cone pulley 103 is adjusted according to need of work
Length, so as to adjust the height of weight.When changing load or needing constantly acting load height, safety pin 202 is inserted into recessed
In through hole 201 in groove 106.Safety pin 202 is deeply and through groove 106 and through hole 201, the fixation cone pulley 103 that can be consolidated,
Prevent that drawstring is quickly drawn back in the case of surprisingly shedding load suddenly, makes staff injured.
Therefore, the utility model uses the Spring balancer of said structure, increases the contact area of cone pulley and safety pin,
Ensure that cone pulley, by safety pin locking, improves the security context of operator.
Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model rather than it is limited
System, although the utility model is described in detail with reference to preferred embodiment, one of ordinary skill in the art should manage
Solution：It can still modify or equivalent to the technical solution of the utility model, and these are changed or equally replaced
Change the spirit and scope that can not also make amended technical scheme depart from technical solutions of the utility model.
