Abstract

The utility model relates to a fork type theft-proof lock for a car which is arranged on an automobile steering wheel, which is composed of a lock body, a lock tongue, an expansion rod, a handle tube, etc., and adopts a cross slot lock core. The handle tube and the telescopic rod are respectively welded with U-shaped hooks. I When the car is locked, the U-shaped hook on the handle tube butts on one end of the steering wheel. The U-shaped hook of the telescopic rod is forked on the other end of the steering wheel, and the expansion rod is strained outwards. So the automobile steering wheel can not rotate, and the theftproof purpose is achieved. The utility model can meet locking of the steering wheels of various cars with the advantages of simple structure, strong shifting prevention property, strong prying prevention property, low cost, and convenient installation and operation.

Description

Fork type theft-proof lock for car

The utility model relates to a kind of lockset, particularly a kind of anti-theft column lock that is contained on the vehicle steering.

Existing automobile generally adopts Door Lock and firing switch lock to carry out locking, because this two kinds of locksets anti-dialled, pick-proof is relatively poor, and its key transreplication, so cause a large amount of vehicles stolen, current, occurred some abroad and planted with infrared ray observing and controlling and electronically controlled burglary insurance device, but its complex structure, cost is higher, installs and uses trouble.

The purpose of this utility model provides a kind of simple in structure at above-mentioned defective exactly, the automobile steering wheel theftproof lock that anti-dial, pick-proof is strong, cost is low, easy to install.

The purpose of this utility model is achieved in that

The V shape automobile anti-theft lock, it is characterized in that: be by handgrip, lockset, the expansion link of band U type hook is formed pipe, wherein being welded with U type hook on the pipe, the expansion link stage casing is respectively equipped with the groove of number joint homotype, and a side of groove is a circular conical surface, and another side is a vertical surface, at the more piece groove stretching outermost block place of expansion link is the fastening grooves of two vertical angles to contact, and expansion link passes lock and is inserted in the pipe.Lockset is to be made of lock body, dead bolt, dead bolt spring and lock core.Expansion link, the pipe and two U type hooks on sheathing is arranged.

Expansion link of the present utility model and pipe selected for use the refined steel manufacturing; There is equally spaced groove in the expansion link stage casing, and is easy to use, the axis of dead bolt and the axis normal of locking bar, withstand the groove of expansion link with the head of dead bolt, thereby make whole dead bolt stressed, reach the tensile strength that strengthens locking mechanism, lock body adopts Zinc alloy die-casting process; Tapered end adopts the assembling of inner sealing structure by the tapered end pin, reaches anti-drilling, anti-and dials, pick-proof, prevents requirement such as foreign matter unlatching; Appearance adopts the soft technology of moulding of thick matter, prevent to damage auto meter and relevant position, and make outward appearance more graceful.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the location of expansion link, the interior assembly structure figure of sealed and tapered end.

Among the figure: 1. lock core; 2. dead bolt spring; 3. dead bolt; 4. lock body; 5. expansion link; 6. pipe; 7. handgrip; 8.U type hook A, 9.U type hook B; 10. key; 11. expansion link groove; 12. sheathing.

As shown in Figure 1, 2: handgrip 7 is to be made by rubber, and handgrip 7 is enclosed within on the pipe 6, and pipe 6 and U type hook A8 are made by steel pipe, and particularly round steel pipe is welded with U type hook 8 managing on 6, and lock body 4 is made for zinc alloy, is drilled with latch arm hole and dead bolt hole on it.Latch arm hole becomes 90 ° of angles with dead bolt hole, with riveting sleeve pipe 6 is fixed on the lock body 4.Expansion link 5 and U type hook B9 are made by carbon steel, and the stage casing of expansion link is processed with the number joint with ring-like valley gutter 11, and expansion link 5E is welded with U type hook B9.Pipe 6, U type hook A, B, 8,9; Sheathing 2 is housed on the expansion link 5.Dead bolt 3 is made for carbon steel rod, its end is tongue type inclined-plane, be mounted in the dead bolt hole of lock body 4, dead bolt is inserted under the effect of dead bolt spring 2 in the ring-like skewed slot of expansion link 5, pull back expansion link 5, under the effect of the circular conical surface of annular skewed slot (less than from the locking angle), move behind the dead bolt 3, can make expansion link 5 outside unilateral stretchings.When promoting expansion link 5 inwards, dead bolt 3 can't move forward being inserted under the effect of dead bolt spring 2 on the vertical surface of expansion link 5 ring-like grooves.Key 10 is inserted in to insert in the lock core 1 turns an angle, just can make dead bolt 3 withdrawals, at this moment, expansion link 5 is convenient to folding and unfolding from pushing inward on earth, during the lock car, with the end of U type hook A fork at bearing circle, U type hook B fork locks dead bolt with key 10 at the other end of putting to dish, outwards pulling expansion link 5 to maximum position withstands on windscreen and the dead angle that car body combines it, and can reach automobile can't steering wheel rotation and theft-proof purpose.This lock construction is simple, anti-to be dialled, pick-proof is strong, cost is low, easy to install, and higher burglary insurance is arranged.
