Description
Technical field
The utility model relates to a kind of cam disk safety thick stick locking and tripper, belongs to field of mechanical technique.
Background technique
Hydraulic pressure or pneumatic system that a lot of safe thick sticks use realize locking and release, and not only cost is high owing to mechanism's very complicated, and rate of fault is high.
Summary of the invention
In order to overcome the deficiency of existing technology, the utility model provides a kind of cam disk safety thick stick locking and tripper,
Locking of a kind of cam disk safety thick stick and tripper comprise spring, by moving cam, actuating cam, tooth bar, safe thick stick, control rod, square guide rod and ratchet, connecting rod.
Firmly be connected with square guide rod and ratchet by moving cam, actuating cam firmly is connected with control rod, tooth bar and rod hinge connection, and safe thick stick and connecting rod are rigidly connected.
The utility model has the advantages that with simple mechanism and realize safe thick stick locking and release action.
Description of drawings
When combining accompanying drawing to consider; Through with reference to following detailed, can more completely understand the utility model better and learn wherein many attendant advantages easily, but accompanying drawing described herein is used to provide the further understanding to the utility model; Constitute the part of the utility model; Illustrative examples of the utility model and explanation thereof are used to explain the utility model, do not constitute the improper qualification to the utility model, like figure wherein:
Fig. 1 is the structural representation of the utility model.
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Embodiment
Obviously, the many modifications made based on the aim of the utility model of those skilled in the art and the variation protection domain that belongs to the utility model.
Embodiment 1: as shown in Figure 1, and a kind of cam disk safety thick stick locking and tripper, structure is formed: spring 1, by moving cam 2, actuating cam 3, tooth bar 4, safe thick stick 5, control rod 6, square guide rod 9 and ratchet 7, connecting rod 8;
The structure explanation: firmly be connected with square guide rod 9 by moving cam 2, an end of square guide rod 9 connects ratchet 7; Actuating cam 3 firmly is connected with control rod 6, and tooth bar 4 is hinged with connecting rod 8, and safe thick stick 5 is rigidly connected with connecting rod 8; Spring 1 is enclosed within on the square guide rod 9, and is positioned at by a side of moving cam 2, and ratchet 7 contacts with tooth bar 4, and connecting rod 8 is connected with safe thick stick 5.
Working principle: when pulling control rod 6 rotations, drive actuating cam 3 rotations; Because action of cam extruding is spurred square guide rod 9 and ratchet 7 also is moved to the left motion by moving cam 2 to left movement; Leave tooth bar 4 and realize safe thick stick release; Safe thick stick can be freely swung, realize safe thick stick release action.
After the release, when pulling control rod 6 to phase opposite direction rotation, then make by moving cam 2 under the pressure of spring 1, to move right, promote to compress the ratchet on the tooth bar 4, this hour rack is by locked, can not drivening rod 8 and safe thick stick 5, and both safe thick stick is locked.
As stated, the embodiment of the utility model has been carried out explanation at length, but as long as break away from the inventive point and the effect of the utility model in fact a lot of distortion can not arranged, this will be readily apparent to persons skilled in the art.Therefore, such variation also all is included within the protection domain of the utility model.
