Technical Field

The invention relates to the technical field of railway vehicle parts, in particular to an adjustable four-corner lock device for railway vehicles.

Background

The four-corner lock is a locking mechanism used by types of , the application is types, rail transit in China develops rapidly in the years, in the rail vehicles, a large number of locking mechanisms are needed to lock certain parts, and the four-corner lock is a locking mechanism used by the current rail vehicles in a type.

The action that used four corner lock of rail vehicle realized at present is that the spring bolt rotates 90 backs, along axial displacement section distances, accomplishes locking or unblank operation present four corner lock device has the limitation that was decided, use position kinds of four corner locks promptly, and the commonality is extremely poor, and the same position if the curb plate etc. is great by locking a tolerance, also can lead to unable locking, locks the rear side board and rocks, unable locking firmly.

Disclosure of Invention

Aiming at the technical problems in the prior art, the invention provides adjustable four-corner lock devices for railway vehicles, which can enable the four-corner lock devices to have an adjusting function within a fixed range of , can be universal at a plurality of positions and can greatly reduce the production cost of the railway vehicles.

The technical scheme for solving the technical problems includes that the adjustable four-corner lock device for the railway vehicle comprises an outer shell and a lock nut, a four-corner lock head, an inner lock sheet, an outer lock sheet, a pin and a lock cylinder are installed in the outer shell, a lock tongue is arranged at the end of the lock cylinder and fixedly connected with the lock cylinder through a nut, and a nut assembly hole capable of adjusting the assembly position of the lock tongue is formed in the lock tongue.

On the basis of the technical scheme, the invention can be further improved as follows.

And , the nut assembling holes are a plurality of round holes which are arranged side by side and can be penetrated by the nuts.

, the nut assembling hole is an elliptical hole.

Preferably, the length of the nut assembling hole is 30-50 mm.

And , forming the nut assembly hole into a long round hole.

Preferably, the length of the nut assembling hole is 30-50 mm.

The four-corner lock has the advantages that the universality is high, the four-corner lock is strong in single in the prior art, the four-corner lock with different specifications and models is designed according to different parts, the universality is high, the four-corner lock is multifunctional, the four-corner lock not only has axial displacement but also has radial displacement, so that the four-corner lock can be used for locking pieces with different tolerances and even different parts, the radial displacement of a lock tongue can be adjusted to realize multiple functions, the economy is realized, the material cost is saved, the four-corner lock is not required to be designed according to each part, the specification of the four-corner lock is unified to , the position of the lock tongue can be adjusted according to different radial displacements, and the lock full-vehicle locking.

Detailed Description

The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention.

In the description of the present invention, it should be further noted that unless otherwise expressly specified or limited, the terms "disposed," "mounted," and "connected" shall be construed , and for example, may be a fixed connection, a removable connection, or a body connection, a mechanical connection, a conduit connection, a direct connection, an indirect connection via an intermediary, and a communication between two elements.

As shown in fig. 1 and 2, the adjustable four-corner lock device for railway vehicles designed by the invention comprises an outer shell 9 and a lock nut 10, wherein a four-corner lock head 1, an inner lock piece 2, an outer lock piece 3, a pin 4 and a lock core 5 are arranged in the outer shell 9.

The end of the lock core 5 is provided with a bolt 6, and the bolt 6 is fixedly connected with the lock core 5 through a nut 7. And the bolt 6 is provided with a nut assembling hole 8 capable of adjusting the assembling position of the bolt 6. During the use, can adjust the position of spring bolt 6 as required, then pass nut pilot hole 8 with nut 7, screw up fixedly, can accomplish the adjustment of spring bolt 6 position.

The invention is characterized in that the bolt 6 is designed, and the bolt 6 is provided with a nut assembling hole 8 capable of adjusting the position of the bolt 6 to realize the adjustment of the assembly.

Example 1

As shown in fig. 3, the nut mounting hole 8 of the locking tongue 6 of the present embodiment is a plurality of round holes arranged side by side and capable of passing through the nut 7.

When in use, the outer shell 9 is firstly assembled on the assembling position of the lock body through the locking nut 10. Then according to the position condition by the part, adjust the position of spring bolt 6, guarantee can better locking by the part, adjust the back that finishes, according to the condition of position control a plurality of round holes that can wear to establish nut 7 of arranging side by side find out suitable hole and wear to establish nut 7, then screw up nut 7 and accomplish the assembly of spring bolt 6.
