Abstract

The utility model relates to a door-lock anti-destruction device for a railway communication signal box-type machine room. The adopted technicial scheme is as follows: the device comprises a lock knob, a lock case, a lock pin and an outer lock, wherein a hole allowing the lock knob to pass through is formed on the lock case; the lock case is connected on the lock pin and can turn over around the lock pin; the lock knob and the lock pin are fixed on a door plate on the outer side of a thievery prevention lock for a door of the railway communication signal box-type computer room; and after the lock case turns over, the lock knob passes through the upper hole of the lock case, the outer lock is inserted into the lock knob, and then the door-lock anti-destruction device is in a locking protection status. The door lock destruction prevention device can cover the keyhole of the thievery prevention lock (inner lock) of the door of the machine room so as to avoid the artificial destruction from directly contacting with the thievery prevention lock; and an outer lock is arranged on the door-lock anti-destruction device to ensure that the door-lock anti-destruction device has a dual-lock structure, so that the difficulty of door opening by artificial destruction is increased, i.e. the door anti-destruction time is prolonged .

Description

The door lock destruction prevention device of the box machine room of a kind of Source of Railway Communication and Signalling

Technical field

The utility model relates to a kind of lock, particularly relates to the door lock destruction prevention device of the box machine room of a kind of Source of Railway Communication and Signalling.

Background technology

Along with the particularly fast development of Line for Passenger Transportation construction of high-speed railway, the signal box house of traditional construction brick mix structure, owing to reasons such as being subjected to specialty, line condition, weather makes construction period long, the on-the-spot workload of installing, debugging, open of indoor equipment is big, time is long, the development need of incompatibility railway construction.And the box room system integrated technology of employing Source of Railway Communication and Signalling, promptly make machine room in factory, carry out indoor equipment installation, preliminary debugging, extremely on-the-spot installation of whole Transporting then, system debug and the mode of opening become a kind of technological revolution measure of high speed railway construction development.

At present, the box machine room of Source of Railway Communication and Signalling is a unmanned, and the door of machine room adopts the theftproof lock that exposes keyhole mostly, because artificial deliberately destruction, foreign matters such as iron wire, waddy are inserted in the keyhole of safe-guard door lock, cause the door of not opening, when particularly being badly in need of entering machine room inside and carrying out plant maintenance, be difficult to open machine room in short time, the equipment Emergency Maintenance that occasions a delay is handled.If foreign matters such as iron wire, waddy can not be taken out from the keyhole of theftproof lock, can only open door in the mode of destroying theftproof lock even destruction door body, cause very the large economy loss, even can not enter machine room inside and carry out plant maintenance and influence railway and normally move because of the long period.

The utility model content

Technical problem to be solved in the utility model is, the door lock destruction prevention device of the box machine room of a kind of Source of Railway Communication and Signalling is provided, it not only can cover in the keyhole of the theftproof lock (internal lock) of machine room door, make artificial destruction can not directly touch theftproof lock, on the door lock destruction prevention device, be provided with an external lock, make the lock of machine room door be set to double-lock structure, increased the difficulty that door is opened in artificial destruction, tamper-proof time of promptly having improved door.

The technical scheme that the utility model adopted is: include lock nose, lock box, lock pin, external lock, have the hole of passing for the lock nose on the lock box; Lock box is connected on the lock pin, and can be around the upset of lock pin; Lock nose, lock pin are fixed on the outside door-plate at the box machine room door of Source of Railway Communication and Signalling theftproof lock place; After the lock box upset, the lock nose passes hole on the lock box, and external lock inserts in the lock nose, and this moment, the door lock destruction prevention device promptly was in the locking guard mode.

In the technique scheme, described external lock is preferably cylinder lock.

The utility model is installed in the outside of box machine room door theftproof lock (internal lock), is fixed on the door by self-plugging rivet.The destruction prevention device agent structure adopts steel plate to make a box-packed structure, and the theftproof lock of machine room door is covered on the box-like destruction prevention device fully from the outside.Box-like destruction prevention device is provided with a cylinder lock (external lock), behind the unlatching external lock, can turn over the lock box of opening destruction prevention device downwards, exposes the keyhole of internal lock, opens internal lock again, the machine room door can be opened.

The beneficial effect of structure described in the utility model is: 1, destruction prevention device agent structure, adopt steel plate to make a box-packed structure, the theftproof lock of machine room door is covered in the box-like destruction prevention device fully, make artificial destruction can not directly touch the keyhole position of theftproof lock (internal lock); 2, be provided with an external lock on the destruction prevention device, make the lock of machine room door be set to double-lock structure, the tamper-proof time .3, the destruction prevention device that have improved door are simple in structure, if low price. artificially the external lock keyhole is blocked and do not opened, the sawed-off external lock lock ring of instruments such as available hacksaw can be opened the lock box of destruction prevention device. and external lock adopts cylinder lock, low price, even destroy, the used time is short, economic loss is little.

The specific embodiment

Make a detailed description below in conjunction with the door lock destruction prevention device of accompanying drawing the box machine room of a kind of Source of Railway Communication and Signalling of the present utility model.

As shown in Figure 1 and Figure 2, the door lock destruction prevention device of the box machine room of a kind of Source of Railway Communication and Signalling, it is installed in the outside of box machine room door theftproof lock (internal lock), is fixed on the door by self-plugging rivet.It comprises that lock nose 1, lock box 2, lock pin 3, external lock 4 form, and wherein locks nose 1, lock box 2, lock pin 3 and is made by steel plate, has the hole of passing for lock nose 15 on the lock box 2, and lock box 2, lock pin 3 link together by the steel bearing pin, and lock box 2 can be around 3 upsets of lock pin.Lock nose 1, lock pin 3 directly are fixed on the outside door-plate at box machine room door theftproof lock place by self-plugging rivet.After lock box 2 upwards overturn, lock nose 1 passed hole 5 on the lock box 2, external lock 4 was inserted in the lock noses 1 again, and this moment, the door lock destruction prevention device promptly was in the locking guard mode.

Fig. 3, Figure 4 shows that the utility model closed rear elevation of locking.The utility model covers on the theftproof lock of machine room door in the box-like destruction prevention device fully, makes artificial destruction can not directly touch the keyhole position 6 of theftproof lock (internal lock).

Fig. 5 has shown the installation site on the box machine room door of the utility model.7 are the utility model door lock destruction prevention device.

Be a kind of mounting means of door lock destruction prevention device shown in the accompanying drawing, also can be with the installation direction Rotate 180 degree among the figure, promptly external lock (cylinder lock) 4 below, lock box 2 upwards upset is opened.In like manner, also can rotate 90 or 270 degree installs.
