Abstract
This utility model provides a novel strengthen lock used by railway transportation, which comprises a lock rod and a lock body assembly, the lock body is consisted of a lock body, steel balls, springs and a plug cap, namely the double-spring and double-steel-ball locking structure is arranged inside the lock body, both ends of the double spring connectively cooperates with the steel ball and the plug cap respectively, and the steel ball locks closely and cooperates with the ring groove of the lock rod. The utility model has the following beneficially positive effects: the head of the locking rod cannot be easily drawn to a groove to cause the secondary sealing execution when the sealing execution is destroyed if the material of the locking rod is relatively soft because of the adoption of the double-steel-ball locking, which makes the locking force more powerful and the locking capability better and safer.
Description
Technical field
The utility model relates to a kind of novel reinforced lock of envelope reinforced lock, particularly railway transportation of executing, and is suitable for the disposable envelope operation of executing.
Background technology
Existing railway reinforced lock, its lock body are the locking modes that adopts the inside groove spring, because unstability, the machine of material material are subjected to that extraneous factor influences, its difficult quality guarantee, make its locking performance be difficult to assurance.
Visitor in the invention
The purpose of this utility model is to overcome the defective of existing railway with reinforced lock, designs the novel reinforced lock of the more superior railway transportation of its performance.
The purpose of this utility model is to realize according to following structure: comprise by locking bar, lock body assembly constituting, the lock body assembly is made up of lock body, steel ball, spring, plug, its architectural feature is: be provided with the two steel ball locking mechanisms of dual spring in the lock body, the two ends of dual spring are connected cooperation with steel ball, plug respectively, and steel ball is locked with the annular groove on the locking bar and cooperated.
The described diplopore that has on lock body is equipped with steel ball and spring, and shuts spring with plug in the hole.
Described locking bar and lock body adopt matched in clearance.
The utlity model has following useful good effect: when the locking bar material was soft partially, owing to adopt two steel balls lockings, when destruction was executed envelope, the locking bar head was difficult for being drawn as groove and produces secondary and execute envelope; Two steel ball lockings make locking force bigger, and the locking performance is better, safer.
Description of drawings
Fig. 1 is a not locking states structure chart of the present utility model.
Fig. 2 is the locking states structure chart of Fig. 1.
Code name implication among the figure: the annular groove on 1 locking bar, 2 lock bodies, 3 steel balls (two), 4 springs (two), 5 plugs (two), 6 locking bars
The specific embodiment
With reference to Fig. 1, Fig. 2, the utility model comprises by locking bar, lock body assembly and constituting, the lock body assembly is made up of lock body 2, steel ball 3, spring 4, plug 5, its architectural feature is: be provided with dual spring 4 locking mechanisms in the lock body, the two ends of dual spring 4 are connected cooperation with steel ball 3, plug 5 respectively, and steel ball 3 is locked with the annular groove 6 on the locking bar 1 and cooperated.On lock body 2, have the diplopore (not shown), steel ball 3 and spring 4 are housed in the hole, and shut spring 4 with plug 5.Locking bar 1 can rotate in lock body 2.Spring 4 energy compressive strains in the lock body assembly, and steel ball 3 can not come off and can transmit the deformation force of spring 4 on locking bar 1 when supporting locking bar 1 contacts.Dual spring 4 in lock body relies on certain angle that steel ball 3 is produced elastic force, realizes the locking performance by the annular groove 6 that two steel balls 3 block on the locking bar 1.
Claims (3)
1. novel reinforced lock of railway transportation, comprise by locking bar, lock body assembly and constituting, the lock body assembly is made up of lock body, steel ball, spring, plug, it is characterized in that: be provided with the two steel ball locking mechanisms of dual spring in the lock body, the two ends of dual spring are connected cooperation with steel ball, plug respectively, and steel ball is locked with the annular groove on the locking bar and cooperated.
