The specific embodiment

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

Fig. 1 shows the internal construction of the utility model " U " type transformer anti-theft lock.In Fig. 1, lock body 8 middle parts are provided with a cavity, make lock body 8 become the two-way enclosed construction of " U " shape.Bolt 1 passes set through hole in lock body 8 tops and the through hole on the transformer cover plate 2, matches with the screwed hole 5 that is located at lock body 8 bottoms, and pad 3 and pad 4 lay respectively between the upper and lower faces and lock body 8 of transformer cover plate 2.The bottom of lock tube 6 is provided with the cavity that can hold bolt 1 head, and the external surface of top and lock body 1 is level mutually, and the middle part is provided with the arc surface cavity that can match with lock core 7, promptly flows glass formula structure, and the dead bolt 9 on the lock core 7 can insert the dead bolt hole 10 that is located on the lock body 8.

Fig. 2 shows the situation that lock core 7 matches with lock tube 6, and shown in the figure is that dead bolt 9 inserts the state that is in pinning in the dead bolt hole 10.

This kind structure, at first be to fasten transformer cover plate 2 with bolt 1, cover the top of bolt 1 with lock tube 6, for preventing that lock tube 6 is removed, match with the arc surface of lock core 7 with lock tube 6, push down the bottom of lock tube 6, with key rotation lock core 7, when dead bolt 9 was stuck in the lock tongue cavity 10, lock tube 6 promptly can not take out from lock body 8, thereby so bolt 1 can not be turned on the purpose that reaches antitheft.

For more reliable, bolt 1 can be made the non-standard bolt of interior five sides, is equipped with outer five side's special tools simultaneously in order to install, to dismantle handled easily.

Simultaneously, lock core 7 is arranged to cruciate flower shape, four row's pellets shot from a slingshot, it is three narrow one wide that four grooves are set to, the lock core of this kind structure is equivalent to four of common lock cores, the key that matches equally also is cruciate flower shape, and this kind cruciate flower key is difficult to imitated, has strengthened anti-theft effect.

Operation for convenience when taking out lock tube 6, is equipped with magnet, adsorbs lock tube 6 with magnet, can easily it be taken out from the cavity of lock body 8.

When the transformer needs are antitheft, " U " type transformer anti-theft lock is installed on the transformer cover plate 2, inserts in the cruciate flower shape lock core 7 and rotation, when hearing click clatter one with cruciate flower shape key, just can take out key, at this moment the dead bolt 9 of cruciate flower shape lock core 7 hangs upside down in dead bolt hole 10.When needs dismounting transformer anti-theft lock, make lock core 7 break away from lock body 8 and dead bolt hole 10 with cruciate flower shape key, open other part more successively and get final product.
