Abstract

The utility model discloses an improved lock rod structure, which is characterized in that the rod part of a lock rod is made of once rolling, so the lock rod presents a continuous peak shape and is suitable for locking various automobiles; if a key is discovered not to be carried before locking, a screw can be screwed out, and then a locking procedure is completed when the screw is inserted into a lock sleeve according to a locking program. The utility model has the advantages of simple manufacturing technique, time saving, labor saving, low cost, and good locking effect.

Description

Structure of lock rod

The utility model relates to a kind of improved Structure of lock rod, and it belongs to the automobile accessories field of components.

At present, social security is not good enough, burglar's wildness, the vehicle thefts rate also rises year by year, come out though existing automobile burglar turns the lock product, because of its manufacturing process complexity, its shaft have tens of sections etc. between pitch, every pitch need save the withdrawing feed during manufacturing, car system repeatedly, complex process, in addition, yield rate is low, cost is high, locking bar is easily loosening, easily injure automobile component, so the popularization rate is lower, and the anti-theft feature of general automotive lock is poorer.

The purpose of this utility model is that a kind of improved Structure of lock rod will be provided, and the pitch of locking bar by a rolling cut moulding of slitting mill, is made easily, and cost is low, the efficient height.

The purpose of this utility model is achieved in that once roll extrusion cutting, integrated thread pitch 11 on the shaft of locking bar 10, and it has suitable inclined-plane 13 and groove 14.

Owing to adopt such scheme, the utility model once gets final product the rolling cut moulding with pitch on the locking bar by slitting mill, has simplified manufacturing process, reduced cost, the yield rate height, it adapts to various model automobiles and uses, vehicle steering, brake plate (or throttle) can be locked, and not injure automobile component.

Below by accompanying drawing and embodiment the utility model is further described.

Fig. 1 is the known lock schematic diagram that turns.

Fig. 2 is present embodiment Structure of lock rod figure.

Fig. 3 is that present embodiment uses schematic diagram.

Among the figure: 10 locking bars, 11 pitches, 12 crutch portions, 13 inclined-planes, 14 grooves, 20 lock tubes, 21 lock tenons.

Referring to Fig. 2: the shaft of locking bar 10 is pressed into automatic roll cutting machine has successional shape of threads pitch 11, be provided with the crutch portion 12 of crooked shape along locking bar 10 ends, wherein the spacing of thread pitch 11 is dwindled than known locking bar, and have suitable inclined-plane 13 and a groove 14, so lock tube 20 in conjunction with the time can with the lock tenon 21 fix mutually, to reach sealed effect, simultaneously, because thread pitch 11 structure pitch of locking bar 10 are dwindled, can adapt to the various different automobile brake plate (or throttle) and the different spacing of steering wheel, it is closely sealed to enable to adjust suitable pitch, and does not injure other parts of car body.

In addition, when locking bar 10 and lock tube 20 before not sealed, when the lock car is not with key, can it slowly be screwed out, and then lock car with locking bar 10 by direction of rotation by normal procedure, like this, just can can't not lock antitheft because of inadvertent.

Claims (1)

1, a kind of Structure of lock rod, it is made up of locking bar and shaft pitch, and it is characterized in that has thread pitch (11) on the shaft of locking bar (10), and thread pitch (11) is and connects peak shape, and the peak side is inclined-plane (13) and groove (14).
