Abstract
The utility model discloses a bidirectional self-locker, which comprises a driving shaft, a driven shaft, a pulling pawl, a self-locking block, a steel ball, a bearing and a mounting seat. One end of the driving shaft is integrally fixedly connected with the pulling pawl, and one end of the driven shaft is integrally fixedly connected with a self-locking block fixing chain. The bidirectional self-locker has the advantages that the bidirectional self-locker is simple in structure, small in volume and light in weight, realizes unidirectional transmission as the driven shaft can be in bidirectional automatic locking, is few in integral components and easy to be assembled, effectively reduces manufacturing and assembling costs, and is simple in transmission.
Description
Technical field
The utility model relates to a kind of mechanically operated from lock construction element, can two-wayly be automatically locked the realization folk prescription to the bidirectional self-locking device that rotates thereby relate in particular to a kind of driven shaft.
Background technique
At present, existing bidirectional self-locking device member mainly contains friction plate self-locking, automatically controlled self-locking and friction self-locking, and these are several from the equal complex structure of lock construction element, the self-locking poor reliability, and efficient is low; And can only satisfy the function of unidirectional self-lock, can not realize the function of driven shaft output terminal bidirectional self-locking.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model purpose is for a kind of simple in structure, two-way locked efficient bidirectional self-locking device of driven shaft output terminal energy is provided.
For achieving the above object, the utility model has been taked following technological scheme:
A kind of bidirectional self-locking device, comprise driving shaft, driven shaft, pusher dog, self-locking block, steel ball, bearing, fitting seat, driving shaft one end and pusher dog are connected to one, driven shaft one end and self-locking block fixed-link are one, the integral structure of driving shaft and pusher dog is connected by bearing with the integral structure of driven shaft and self-locking block, and place in the fitting seat, it is characterized in that: described self-locking block is being protruding structure on the cylinder of driving shaft one end, form four jagged grooves that are symmetrically distributed between self-locking block and the fitting seat.
In the technique scheme, described steel ball places in described four jagged grooves.
In the technique scheme, the both sides of the cylinder that described pusher dog is connected with driving shaft have the pawl of two projectioies.
Compared with prior art, the utlity model has following beneficial effect:
1. the element structure that is automatically locked of the present utility model is simple, has the characteristics of simple transmission, and whole composed component is few, assembly easily, and reduce the cost of making and assembling effectively;
2. the utility model transmission efficiency height, minimizing resistance heating, locked safer reliable can be widely used in automatic control or other mechanical transmission fields, have great economic benefit, and use should be widely promoted.

Specific embodiment
The utility model will be further described below in conjunction with Figure of description, but the utility model scope required for protection is not limited to the scope that mode of execution is described.
As shown in Figure 1 to Figure 3, a kind of bidirectional self-locking device, comprise driving shaft 1, driven shaft 2, pusher dog 3, self-locking block 4, steel ball 5, bearing 6, fitting seat 7, driving shaft 1 one ends and pusher dog 3 are connected to one, driven shaft 2 one ends and self-locking block 4 fixed-link are one, the integral structure of driving shaft 1 and pusher dog 3 is connected by bearing 6 with the integral structure of driven shaft 2 and self-locking block 4, and place in the fitting seat 7, it is characterized in that: described self-locking block 4 is being protruding structure on the cylinder of driving shaft 1 one ends, form four jagged spaces 41 that are symmetrically distributed between self-locking block 4 and the fitting seat.
Described steel ball 5 places in four jagged spaces 41.
The both sides of the cylinder that described pusher dog 3 is connected with driving shaft 1 have the pawl 31 of two projectioies.
Working principle is as follows:
As Fig. 2, when working method is that driving shaft 1 drives pusher dog 3 and rotates, and rotates together Yi Bian pusher dog 3 pushes drive steel ball 5 to self-locking block 4 again when driving driven shaft 2 by driving shaft 1, self-locking block 4 connects with driven shaft 2, thereby drive driven shaft 2 rotates together.
When driving shaft 1 is motionless, pusher dog 3 is also motionless, if rotate driven shaft 2, driven shaft 2 rotates with self-locking block 4, but this moment, steel ball 5 was stuck with fitting seat 7 with self-locking block 4, because self-locking block 4 is clockwise with to rotate counterclockwise direction all stuck by steel ball 5, thereby realize the bidirectional self-locking of driven shaft 2.
