Description

Door lock device for railway carriage

Technical Field

The utility model relates to a rail vehicle equipment field relates to a novel locks of passenger train device particularly.

Background

Doors in rooms on railway cars require door locks to be installed to enable locking of the doors. Most of the existing door lock devices for railway passenger cars are designed more traditionally, and the door lock cannot be reliably locked from the inside. In a passenger car toilet or a key store, a person in a room needs to lock a door tightly to prevent a person from suddenly entering from the outside. The internal fixed locking ability of the existing door lock device is not enough, and the installation of the bolt in the interior of the door of the railway passenger car is very troublesome, so that the installation quantity is increased, and the door lock device is not installed together, so that the operation is more troublesome.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the main technical problem who solves provides a novel locks of passenger train has effectively improved inside fixed locking ability, and easy operation is convenient moreover, can install on doors such as passenger train's lavatory or storehouse.

In order to achieve the above object, the present invention provides the following technical solutions:

This novel locks of passenger train device includes the lock body, lock body internally mounted has lock core and spring bolt, the lock core is furnished with the key control spring bolt and stretches out and draws back, the spring bolt outside is furnished with the hasp board that the cross-section is "nearly" font, all open a plurality of mounting holes on lock body and the hasp board, the spring bolt extensible runs through whole hasp board, and the spring bolt passes the top of hasp board and opens and have columniform bolt hole, the hasp board is connected with columniform bolt through the chain, the diameter of bolt equals the diameter in bolt hole, and the length of bolt is greater than the length in bolt hole.

As a further optimization of the technical scheme, the lock body, the lock cylinder and the lock tongue are all made of stainless steel.

As a further optimization of the technical scheme, the lock catch plate and the plug pin are both made of stainless steel.

As a further optimization of the present solution, the chain is made of stainless steel, and the chain is connected with the locking plate and the latch by welding.

The beneficial effect of adopting above technical scheme is: this novel locks of passenger train can pass the mounting hole through the screw when installation and install the lock body on the door in passenger train room, fixes the hasp board in the suitable position on the door frame in passenger train room. The user can insert the key into the lock core to rotate the lock tongue to stretch in the lock catch plate to switch the door lock. And the people in the room can insert the bolt downthehole, fixes the spring bolt on the hasp board inside, lets outside personnel can't open the lock, and the operation is very simple, but very reliable. This novel door lock device of passenger train has effectively improved inside fixed locking ability, and easy operation is convenient moreover, can install on doors such as passenger train's lavatory or storehouse.

Detailed Description

The preferred embodiment of the novel door lock device for passenger train of the present invention is described in detail below with reference to the accompanying drawings.

Fig. 1 and fig. 2 show the specific implementation of the novel door lock device of the railway carriage:

combine fig. 1 and fig. 2, this novel locks of passenger train include lock body 1, 1 internally mounted of lock body has lock core 2 and spring bolt 3, lock core 2 is furnished with the key and controls spring bolt 3 and stretch out and draw back, 3 outsides of spring bolt are furnished with the hasp board 5 that the cross-section is "nearly" font, all opened a plurality of mounting holes 8 on lock body 1 and the hasp board 5, spring bolt 3 extensible runs through whole hasp board 5, and spring bolt 3 passes the top of hasp board 5 and opens and have columniform bolt hole 6, hasp board 5 is connected with columniform bolt 4 through chain 7, the diameter of bolt 4 equals the diameter of bolt hole 6, and the length of bolt 4 is greater than the length of bolt hole 6.

The lock body 1, the lock cylinder 2 and the lock tongue 3 are all made of stainless steel, and are firm, durable and good in corrosion resistance. The lock body 1, the lock core 2 and the bolt 3 are all the existing door lock device technologies, and are not repeated here. The lock catch plate 5 and the bolt 4 are both made of stainless steel, and are firm, durable and good in corrosion resistance. Chain 7 is made by the stainless steel, and is sturdy and durable, and corrosion resisting property is good, and chain 7 is connected with hasp board 5 and bolt 4 through the welding, and guarantee bolt 4 can run through and insert spring bolt 3.

This novel locks of passenger train can pass mounting hole 8 through the screw when installation and install lock body 1 on the door in passenger train room, fixes hasp board 5 in the door frame in passenger train room suitable position to guarantee spring bolt 3 can run through hasp board 5, lets bolt hole 6 expose completely in the outside of hasp board 5. The user can insert the key into the lock core 2 to rotate the bolt 3 to extend and retract in the lock catch plate 5 to switch the door lock. And the people in the room can insert bolt 4 in bolt hole 6 of spring bolt 3, fix spring bolt 3 on hasp board 5 inside, let outside personnel can't open the lock, and the operation is very simple, but very reliable. This novel door lock device of passenger train has effectively improved inside fixed locking ability, and easy operation is convenient moreover, can install on doors such as passenger train's lavatory or storehouse.

The above is only the preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many variations and modifications can be made without departing from the inventive concept, and these all fall into the protection scope of the present invention.
