Description

Nut lock for movable apparatus

The utility model relates to the lockset that movable equipment is used.

Some small-sized movably equipment are as 3 horsepowers, 12 horsepower diesels, motor and so on, in light weight because of it, easily move, be easy to stolenly, particularly ineffective small business of defence measure or rural area are arranged on open-air agricultural machinery and implement, stolen phenomenon often takes place, both influenced production, brought economic loss again, in the lockset of prior art, safe-guard door lock, lock are of a great variety, but the lockset that the locking mini-plant is used also still belongs to vacancy.

The purpose of this utility model is to avoid the defective of prior art and provides a kind of mobile device with anti-theft feature to lock with anti-theft nut.

The utility model has following accompanying drawing.

Fig. 1 is the utility model structural representation.

Fig. 2 is the A-A sectional view of Fig. 1.

Fig. 3 is the B-B sectional view of Fig. 1.

In conjunction with above-mentioned accompanying drawing the utility model is described in detail.

Referring to Fig. 1～3, mobile device has a lock body (1) that is equivalent to nut with anti-theft nut lock, lock core (4), pellet shot from a slingshot (6), spring (10) are housed in the lock body (1), and pellet shot from a slingshot (5) is a location lock core (4), according to the needs of lock core (4) rotational angle, offer the arc groove of pellet shot from a slingshot.Stage clip (13) resets lock core, and all seal with stifle (11) in aperture, pellet shot from a slingshot hole.Lock body also is processed with screw and pin-and-hole on (1), and screw, pin-and-hole and lock core hole constitute the three-dimensional apertures that interpenetrates, the i.e. hole of X, Y, three directions of Z.Screw is a through hole, is threaded with bolt (2), and bolt (2) head is processed into flat department.Must allow lock core (4) be positioned at lock core hole during pin hole processing and go to the opening position, therefore when pin-and-hole is processed into after, because both vertical relations, the head of lock core (4) just formation has the arc surface of high plush copper.Pin (3) is housed in the pin-and-hole, and pin (3) is Yi Bian cut an inclined-plane, and the flat department on this inclined-plane and the bolt (2) matches, and relies on the plane that should coincide to make the lock body (1) of spinning on bolt (2) can't rotate the purpose that dismounting reaches locking device (8).The another side of pin (3) has breach, and the inner is fixed with little spring (12), and available technique for sticking solves.

Must be when originally being locked in locking mobile device (8) by fixing equipment or building or heavy frame (9) facility.Bolt (2) is passed the ready-made through hole of frame (9) and mobile device (8), press pin (3) when locking, the inclined-plane of pin (3) and the flat department plane of bolt (2) are matched, the plush copper of lock core (4) is advanced pin (3) gap position with regard to commentaries on classics is located pin, key can be transferred to, and machinery equipment (8) is promptly locked.Nut on the bolt (2), packing ring (7) axial restraint machinery equipment (8) is utilized original 4 fot screws of machinery equipment, as long as 1 of repacking utilizes this lock to lock.

When unblanking, inject key rotation lock core (4), make the plush copper of lock core (4) produce pin (3) breach, pin (3) is just overhanging under little spring (12) effect, at this moment just can take out pin (3), releasing is to the effect of bolt (2), and lock body (1) can turn break away from bolt (2), just machinery equipment (8) can be taken out then.

Cause and can't unblank in order to prevent dust from entering lock core hole, therefore available rubber glue lock core hole is torn during unlatching and is got final product.

Mobile device by the utility model design is locked with anti-theft nut, for light-duty movably equipment provides a kind of lock, has avoided unnecessary economic loss, promotes production development, has increased the newcomer for lockset family simultaneously.

Claims (3)

1, a kind of mobile device is locked with anti-theft nut, comprise lock body (1), lock core (4) is housed in the lock body (1), pellet shot from a slingshot (6), spring (10), silently (11), the pellet shot from a slingshot (5) of location lock core (4) and the stage clip (13) that lock core (4) is resetted, it is characterized in that this lock body (1) has screw and pin-and-hole, they and lock core hole constitute the three-dimensional apertures that interpenetrates, the bolt (2) of the flat department of head is housed in the screw, the pin (3) on band breach and inclined-plane is housed in the pin-and-hole, its plush copper of rotational lock core (4) can pass in and out pin (3) breach, and the inner of pin (3) is fixed with little spring (12).

2, anti-theft nut lock as claimed in claim 1 is characterized in that the flat department of bolt (2) head and pin (3) inclined-plane match.

3, anti-theft nut lock as claimed in claim 1 is characterized in that also being equipped with on the bolt (2) nut, packing ring (7).
