Abstract
The invention belongs to the technical field of light rail transportation, particularly relates to a quick locking mechanism, and aims to provide the quick locking mechanism capable of meeting the requirements, for safety, reliability, operation simplification and maintenance simplification of a locking mechanism, of a vehicle. The quick locking mechanism has the advantage that through the connections among such parts as a lock hook, a lock hook torsional spring, a lock shaft and a lock shaft torsional spring, an object to be maintained on a light rail transportation vehicle can be quickly locked or unlocked.
Description
Technical field
The invention belongs to railway technical field of transportation, particularly a kind of Quick locking mechanism.
Background technology
Along with the fast development of urban rail transit in China, the city of various places all increases railway traffic to alleviate the traffic congestion phenomenon in city in consideration.The fast development of rail vehicle, to the safety of self product, reliability, be easy to operation and maintenance aspect requirement also more and more higher.Locking mechanism, as parts vehicle needing quick release and locking, also needs to adapt to more and more higher requirement.
Summary of the invention
The object of this invention is to provide a kind of Quick locking mechanism, with meet vehicle to locking mechanism safety, reliability, be easy to the requirement of operation and maintenance aspect.
The present invention includes mount pad, latch hook, latch hook torsion spring, lock shaft holder, lock shaft torsion spring, lock shaft.When with key twisting lock shaft, the backstop on lock shaft is decontroled, latch hook automatic spring under the effect of latch hook torsion spring.Latch hook does backstop by the bulge-structure of latch hook oneself after ejecting, and ensures that lock maintains opening.When promoting latch hook arrival latched position, lock shaft resets under the effect of lock shaft torsion spring, blocks latch hook and carries out locking.Lock shaft remains on permanent position by lock shaft torsion spring, and when not having external force, latch hook cannot be opened voluntarily.
In a word, modular construction of the present invention, manufacturing process are all fairly simple, and manufacturing cost is also lower, and structural safety is reliable, and market prospects are good.

Fig. 2 is the lateral view of the embodiment of the present invention
Fig. 3 is front view and the top view (opening) of the embodiment of the present invention
Mark in figure:
1. mount pad, 2. latch hook, 3. latch hook torsion spring, 4. lock shaft holder, 5. lock shaft torsion spring, 6. lock shaft.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are specifically described:
With reference to accompanying drawing 1-3, embodiments of the invention: be fixed on mount pad 1 by the fixed axis on latch hook 2 through after latch hook torsion spring 3, latch hook torsion spring 3 one end is arranged on latch hook 2, and the other end is arranged on mount pad 1.By lock shaft torsion spring 5 through on lock shaft 6, put on a lock shaft holder 4 respectively from the two ends of lock shaft 6, then lock shaft fixed head 4 is fixed on mount pad 1.Lock shaft torsion spring 5 one end is fixed on the backstop place on lock shaft 6, and the other end is fixed on torsion spring mount pad 4.When with key turns lock shaft 6, lock shaft 6 rotates around the axis of rotation of self, and the backstop on lock shaft 6 leaves catch positions because rotating, latch hook 2 is opened under the effect of latch hook torsion spring 3 because not having backstop, after taking off key, the backstop on lock shaft 6 is stoped by the projection of latch hook 2 self, can not reset.When needing locking, promote latch hook 2, when latch hook 2 arrives locked position, the projection of latch hook 2 self can not continue the backstop stoping lock shaft 6, and the backstop of lock shaft 6 resets and remains on locked position under the effect of lock shaft torsion spring 5, latch hook 2 locking and can not opening voluntarily.
Claims (5)
