The length of described locking bolt lengthening part 4 thinks that 2 times of the matched key total length are optimum.
A kind of key of U type bolt formula theftproof lock comprises that key body 5 and key 7, is characterized in that: also comprise the shank of the key 6, described the shank of the key 6 described key bodies 5 of connection and key are 7, and the length of described the shank of the key 6 and described U type bolt formula theftproof lock are complementary.
This theftproof lock that the utility model provides with very low cost, has greatly increased the difficulty that the burglar damages lockset, makes the car thief hang back, and has protected the safety of vehicle.
Description of drawings
Fig. 1 is a theftproof lock schematic diagram described in the utility model;
Fig. 2 is a key schematic diagram described in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated.
As shown in Figure 1: bolt formula theftproof lock of the present utility model has locking bolt 3, lockset is installed in an end of locking bolt 3, and the other end or be connected with lock bridge 2 by the rotation section perhaps is connected with lock bridge 2 with inserted mode, because lockset is installed in end points, keyhole can be touched by foreign object.Now, according to the technical solution of the utility model, change the shell length of locking bolt 3, the invariant position of lockset, in other words, increased the lengthening part 4 as the locking bolt in the technical solutions of the utility model, this lengthening part can be by welding, also can by with existing locking bolt 3 as an one piece machine-shaping, adopt existing material.Because lockset still is in original position, foreign object can't touch lock body, can't directly destroy lock core, so be difficult to open theftproof lock with external force.In order to open this theftproof lock, also need the shank of the key lengthening could normally be opened theftproof lock.
