Description

A kind of racing lock

Technical field

The utility model relates to a kind of racing lock, particularly relates in a kind of racing lock and can identify whether original key is inserted into the device of position.

Background technology

Racing lock is a kind of known mechanical anti-theft lock in Chinese lockset industry, its advantage is: the lock gall just idle running when being twisted lock gall by unlocking tool violence by force and rotating, but lockset cannot be made to be unlocked, and only have the lockset when being rotated by original key twisting lock gall just can be unlocked, therefore, racing lock is a kind of known mechanical lock with better pick-proof performance in Chinese lockset industry.Shortcoming is: existing racing lock is when being opened by original key, when original key is not inserted into position, lock gall also can be rotated by original key twisting, certainly, when this original key is not inserted into position, even if lock gall is rotated also just idle running by twisting, therefore lockset is not unlocked.From feel, this shortcoming that existing racing lock exists cannot judge whether original key is inserted into position when user can be caused to use original key normally to open, this is very inconvenient for user, especially be in a hurry when hurrying to unblank, insert original key, reverse a few circle, lockset is not unlocked and just finds that original key is not inserted into position, time in a hurry, occur that this situation allows very much people unhappy, in addition, also there is severe compromise in this shortcoming, for door lock of registering one's residence, when user is on the trail of by lawless person, user is after running home, certainly be draw key as early as possible to open the door and to enter the room escape from danger, and in emergency circumstances this, people often key completely insert door lock be just eager twist key, and existing racing lock also exists the defect that the key when original key is not inserted into position also can twist lock gall rotation, this can cause user cannot recognize that key is not inserted into position from feel, user can be caused could not to open the door rapidly for a long time escape from danger of entering the room because of hand by mistake, this virtually pulls up to user to lawless person and provides the more time, for user, this is very unpractical, also there is severe compromise.

Summary of the invention

Technical purpose of the present utility model overcomes above-mentioned deficiency of the prior art, a kind of racing lock is provided, described a kind of racing lock has the performance whether identification original key is inserted into position, its performance is: when original key inserts keyhole when not being inserted into position completely, original key cannot twist lock gall and rotarily open lockset, and only having after original key is inserted into position completely, original key just can possess the condition that twisting lock gall rotarily opens lockset.

In order to solve the problems of the technologies described above, the utility model provides following technical scheme, specific as follows:

A kind of racing lock, comprise shell, lock gall, described outer casing inner wall is provided with lock gall locating slot, and described lock gall is located in described shell, and described lock gall is provided with positioning ejection subchannel, and be provided with location pellet in described positioning ejection subchannel, described lock gall is also provided with keyhole.

the beneficial effects of the utility model are:a kind of racing lock of the utility model has the performance whether identification original key is inserted into position, this technology has been filled up racing lock and has not been identified whether original key is inserted into the blank of the device of position, make the practicality of racing lock, safety further promoted, provide better basis for racing lock benefits the society.
