Abstract

The utility model relates to a brake torsion spring which is used for a self-locking, a reset mechanism, a brake mechanism, etc. The utility model is characterized in that a hook horse whose size is bigger than a diameter of a steel wire of the torsion spring is arranged on one end part or both end parts of the torsion spring; the inner side of the hook horse is an arc matched with an inner diameter of the torsion spring. The utility model has the advantages than the utility model can bear larger braking force, the utility model needs small torque when the torsion spring is loosened, etc.

Description

Brake torsion spring
The utility model relates to a kind of Brake torsion spring.
At present, common Brake torsion spring utilizes the steel wire of torsion spring end to curve gib head, and its shortcoming is that bigger braking force can not be born in its end, though can adopt thicker steel wire to make torsion spring, can produce simultaneously and unclamp the bigger shortcoming of the required moment of torsion of torsion spring.
The purpose of this utility model is the deficiency at common Brake torsion spring, provides a kind of and can bear bigger braking force, again can be when unclamping torsion spring the less Brake torsion spring of required torque.
The utility model contains torsion spring, is provided with the hook horse in the end, one or both ends of torsion spring, and the hook horse is the size brake slipper bigger than the steel wire diameter of torsion spring, and its inboard is the arc that cooperates with the torsion spring internal diameter.
The utility model, the torsion spring end that the hook horse is set can be made into direct rod shape, and hook is provided with the jack that cooperates with torsion spring end straight-bar at once, and the torsion spring end all links by jack and hook horse.
The utility model, the connecting ground hook horse material of torsion spring end and hook horse different adopt welding, bonding, riveted joint or with mechanical link such as screw thread, pins.
The utility model has following advantage:
1, utilizes than the big hook horse of steel wire diameter as brake slipper, can bear braking force;
2, need not add heavy wire, make full use of the tensile strength of steel wire, simultaneously, when unclamping torsion spring, required torque is less.
The utility model is widely used in the mechanisms such as various simple self-lockings, playback, braking.
Following embodiment is further described the utility model in conjunction with the accompanying drawings.
Fig. 1, Fig. 2 are the utility model embodiment 1 structure principle charts, and wherein, Fig. 1 is a plan view, and Fig. 2 is a left view;
Fig. 3 is the utility model embodiment 2 a structure principle chart.
With reference to Fig. 1, Fig. 2, direct rod shape is made in an end 11 of the torsion spring 1 of present embodiment 1, and this more easily assembles, and links a hook horse 2 at the straight-bar position, and the hook horse is the size brake slipper bigger than steel wire diameter, and hook horse inboard 22 is the arc that cooperates with the torsion spring internal diameter.Hook is provided with the jack 21 that cooperates with torsion spring end straight-bar at once, and the torsion spring end is by jack and hook horse solder joint.Certainly, the connecting ground hook horse material of hook horse and torsion spring different also can be adopted bonding, riveted joint or with mechanical link such as screw thread, pins.
With reference to Fig. 3, present embodiment 2 is that with embodiment 1 difference embodiment 1 link a hook horse in an end of torsion spring, and embodiment 2 respectively links a hook horse according to the requirement of bi-directional braking in two ends of torsion spring according to the requirement of one-way brake.
The utility model, the requirement of its axially displaced trend when on axle, sliding according to torsion spring, torsion spring can be dextrorotation, also can be left-handed.

Claims (3)

1, a kind of Brake torsion spring contains torsion spring (1), it is characterized in that: the end, one or both ends (11,12) at torsion spring is provided with hook horse (2), and the hook horse is the size brake slipper bigger than the steel wire diameter of torsion spring, and its inboard (21) are the arc that cooperates with the torsion spring internal diameter.
2, Brake torsion spring according to claim 1, it is characterized in that: the described torsion spring end (11,12) that the hook horse is set is direct rod shape, described hook horse (2) is provided with the jack (21) that cooperates with torsion spring end straight-bar, and the torsion spring end links by jack and hook horse.
3, Brake torsion spring according to claim 2 is characterized in that: the binding of described torsion spring end and hook horse is adopted welding, bonding, riveted joint or with screw thread, pin binding.
