Description

Drawing of a kind of railway signal transformer tank anti-theft device buckled

Technical field

The utility model relates to a kind of accessory of railway signal transformer tank anti-theft device.

Background technology

Railway is distributed with many transformer tanks that control train signal device therefor is housed along the line at present.Its safety precautions mainly adopts snap close, lock nose to add the method for common padlock, and its theftproof performance is relatively poor.In order to strengthen protection, occurred some in recent years and cooperated the anti-theft device of existing signal transformer case.Generally all utilized the lock nose of existing signal transformer case and bolt to carry out work, lock nose self size of signal transformer case and installation dimension are ununified at present, and the casing of very most signal transformer case is that hinge type is connected with bolt, the lock nose curves semi-circular shape with round steel, its height has from tens millimeters to 30 millimeters, owing to can not change the signal transformer case, therefore require signal transformer case anti-theft device can be fit to existing signal transformer case and use comprehensively.

It is that 200620041216.3 of ZL are called the patent of " railway signal transformer tank anti-theft device " that State Intellectual Property Office of the People's Republic of China disclosed the patent No. on March 28th, 2007; its lock mode to the signal transformer case is a kind of typical mode; if but be used in casing and bolt be hinge type be connected the signal transformer case time; because bolt can rotate around twisted axis; the lock body that is connected on the bolt also can rotate around twisted axis; when the lock nose is shorter; the lock nose can not stop the lock body rotation; up to lock body whiz transformer case lid, lose protective effect to the signal transformer case.

Summary of the invention

The purpose of this utility model is; A kind of member is provided, cooperates signal transformer case anti-theft device to use, can stop the rotation of signal transformer case bolt, anti-antitheft device lock body loses protection to casing, strengthens antitheft effect.

The utility model is achieved in that drawing of a kind of railway signal transformer tank anti-theft device buckle, this draws and is buckled with a base plate, and a side of base plate is provided with bolt hole, and the opposite side of base plate is provided with lock nose groove, the both sides of lock nose groove are provided with pair of side plates, and side plate is provided with corresponding lock hole.

The bolt hole of described buckle is an elliptical aperture.

Described side plate is established 3 to 5 pairs of lock holes.

Bolt with the signal transformer case during use penetrates the described bolt hole of buckleing that draws, and the lock nose of signal transformer case case lid places described drawing in the lock nose groove of buckleing, and penetrates pin in suitable lock hole, adds lock body and pins the signal transformer case.

To casing and bolt is the signal transformer case that hinge type is connected, use on the unconventional nut in the method for aforementioned bolt and carry out when antitheft, use the utility model can prevent that the transformer tank bolt from rotating around twisted axis, and then prevent that lock body from rotating around twisted axis, improve its theftproof performance greatly.

Fig. 2 is the utility model Fig. 1 vertical view;

Fig. 3 is the utility model user mode structural representation.

Among the figure: base plate 1 bolt hole 2 lock nose grooves 3 side plates 4 lock holes 5 the utility model draw button 6 transformer tank case lids 7 transformer tank casings 8 lock bodies 9 lock noses 10 pins 11 bolts 12

The specific embodiment

The utility model will be further described below in conjunction with accompanying drawing:

Fig. 1 and Fig. 2 are embodiment of the present utility model, and the described button that draws is provided with base plate 1; One side of base plate 1 has bolt hole 2, adjusts for convenience, and it is oval that bolt hole 2 is preferably, and the size of bolt hole 2 should be mated with bolt 12; The opposite side of base plate 1 is provided with lock nose groove 3, and lock nose groove 3 is used for holding lock nose 10, and its width should be greater than the width of lock nose 10; Both sides at lock nose groove 3 are provided with pair of side plates 4, have lock hole 5 on the side plate 4, and lock hole 5 is corresponding in pairs the setting on biside plate 4, wear pin during for locking lock nose 10 and use.

As shown in Figure 3, it much is that transformer tank casing 8 is connected for hinge type with bolt 12 that existing signal transformer case has, transformer tank case lid 7 is provided with a lock nose 10 that curves with round steel, and an opening is arranged on the transformer tank case lid 7, does not therefore hinder bolt 12 to inner rotary; Cover transformer tank case lid 7 during utilization, forward bolt 12 to upright position, put the utility model and draw button 6, draw the bolt hole 2 of button 6 to be enclosed within on the bolt 12 the utility model, lock nose 10 on the transformer tank case lid 7 is placed in the lock nose groove 3, select suitable lock hole 5 to put on pin 11, cover upper lock body 9 tightens and gets final product.Because the utility model draws button 6 existence, bolt 12 can not rotate again, overcome that former there is something special follows bolt 12 rotations because of lock body down and lose lock function to the signal transformer case.
