Abstract
The utility model provides a locking device for a fastener, which comprises a bolt and a nut of a fastening stand-by piece. The utility model is characterized in that a lock seat is arranged between a fastening nut and the stand-by piece; a threaded hole and a locking hole are arranged on the lock seat, and the axial cords of the threaded hole and the locking hole are vertical to each other; a retaining nail hole which is communicated with the locking hole is arranged on one side of the locking hole, which is near the threaded hole. The retaining nail hole causes that the fastener which is bare can not rotate. Stand-by articles which are fastened are effectively protected from other people's theft and use. A user's economic loss is avoided. Simultaneously, lawbreakers are caused to have no opportunity to take advantage of. The behaviors of theft are fundamentally stopped. The utility model has the characteristics of simple structure, superior antitheft performance, convenient operation, etc., and is a really ideal locking device for a clamping device.
Description
Technical field
The utility model relates to a kind of locking device, the especially a kind of device that can lock or protect fastening piece,
Background technique
Usually in many cases, for anti-just in case, all to be equipped with required acknowledgment copy, as the spare tyre of automobile, the perhaps acknowledgment copy of other occasion etc.Owing to be subjected to the restriction in space, many acknowledgment copies can only be installed in the outside by fastening piece, and fastening piece itself is also exposed outside, and do not have any locking device and can prevent that fastening piece from can not turn.Therefore, the stolen incident of walking of above-mentioned standby object often taking place, cause than the large economy loss to the user, especially concerning the more expensive acknowledgment copy of price, more become the target of attack of stealer, therefore, is necessary prior art is improved.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of prior art, provides a kind of safe and reliable, and theftproof performance is good, the fastening piece locking closure that cost is low.
The utility model is realized by following technical proposal: it comprises the screw bolt and nut of fastening acknowledgment copy, it is characterized in that being provided with lock between tightening nut and the acknowledgment copy, lock is provided with vertical each other screw of its axis and lockhole, and is provided with the non-return nail hole that is communicated with lockhole at lockhole near screw one side.
Screw on the described lock is a through hole, and an end in hole is a nut bore, so that the fastening screw screw bolt and nut is placed in one.
Lockhole on the described lock is located at screw one side, and its axis is vertical each other with the screw axis, by fixing nail tapered end is housed in the lockhole.
The axis in described non-return nail hole is vertical mutually with the lockhole axis, the non-return nail that vertical setting is arranged in the hole, stretch out in the sour jujube groove that is placed on the nut lower end upper end of non-return nail, the lower end of non-return nail is provided with the maintenance spring, the middle-end of non-return nail is provided with dead bolt and puts groove, by stirring of dead bolt, make non-returnly to nail on, move down, thereby realize locking or unblanking nut.
The utility model compared with prior art has following advantage and effect: pass through such scheme; exposed fastening piece can't be rotated; effectively protected fastened standby article not usurped by other people; avoid economic loss of user; those lawless persons are had no exploits, fundamentally stop the pilferage behavior.Characteristics such as other the utility model also has simple in structure, and theftproof performance is superior, and is easy to operate, real is a kind of desirable fastening piece locking device.
