Abstract

The utility model provides an adjustable number type puzzle lock for valve which relates to the field of lockset. The utility model comprises a lock body, a locking pressboard and a fixed link. The adjustable number type puzzle lock for valve is characterized in that a lock pin is arranged in the body of the puzzle lock. A letter disc compounded by plastic iron and a disc core pressed by zinc alloy are assembled as the lock body by a harness. A three digits cipher composed by three number letter discs, the locking pressboard and the fixed link of the lock are matched with each other so that the head of the switch screw rod of the valve is locked. The lock has the advantages of convenient and fast opening and various lock numbers. One lock with jack per line is only appeared in every one thousand locks. High-strength materials are adopted by the lock body, the locking pressboard and the fixed link so that the lock is not easy to cut off and break open, and the lock is safe and reliable. A new cipher is built by adjusting numbers to lock once the cipher is leaked.

Description

Adjustable number formula valve coded lock

The utility model relates to field of lockset, specifically a kind of adjustable number formula valve coded lock.

Existing valve lock mostly is iron chains greatly and adds common padlock, uses extremely inconvenient.Though part special service valve door lock is arranged, all to use key operatedly, fastness is not enough, and even more serious is that common lockset keyhole is stopped up by sand-lime easily, or is frozen at the northern area lock core winter and can not opens and cause damage.

The purpose of this utility model is at above-mentioned defective, provides a kind of keyhole can not be plugged, and lock core can not be frozen in, the safe and reliable coded lock that energy need not be key operated.

The utility model is to realize by following technical scheme: use the letter disk of moulding iron and being composited, the dish core of kirsite compacting, form a password with three number letter disks, the unlatching of control coded lock is used with the pass.For easy to use, in case password is revealed, when needing the change password, can adjust number voluntarily, use the new password of determining to lock.Convenient, feasible.

This lock is made up of lock body, locking pressure plate, fixed rod seat three parts.One sets of numbers letter disk is housed in the lock body, number letter disk ABS plastic, the iron ring that liner 0.5 cold-reduced sheet is made, compound through zinc-plated and plastics, the figure disc core adopts the kirsite compacting, and the outer ring is established ten five equilibrium locating slots, 36 degree and is done the letter disk location and use.Lock core adopts wear-resistant plastic, by fixed cover its combo is become lock body.The lock body upper end is locking pressure plate and helical teeth bar, and the lower end is fixed bar, base, screw, locknut, fastens the valve screw head by locking pressure plate, and fixed rod seat adds screw lock is secured on the valve block.Height according to all kinds of valve screws does not wait, but helical teeth bar easy on and off regulate, two bars all use 25 * 5 band steels to make, through Overheating Treatment, chromium plating, intensity height, fastness are good, difficult pincers break, pry open, insure reliable.

The utility model has the advantages that with three number letter disks and form different passwords, each is organized password and has nothing in common with each other, and has only a jack per line in 1,000 locks, cryptographic capabilities is very reliable, and is easy to use, as long as remember password, start or stop also can be avoided losing the trouble of bringing because of key freely.This lock has adjustable number structure, needs to change original code in case reveal because of personnel change or password, can adjust one group of password of number array Cheng Xin voluntarily, and is convenient rapid.The intensity of this lock is higher, so performance substantially exceeds existing lockset.

The utility model concrete structure is provided by following examples and accompanying drawing.

Accompanying drawing 1 is a structure chart of the present utility model.

Accompanying drawing 2 is adjustable combination lock cored structure figure of the present utility model.

Accompanying drawing 3 is a user mode schematic diagram of the present utility model.

This lock mainly is made up of locking pressure plate (1), lock body (14), (8) three parts of fixed bar.Through Overheating Treatment, the helical teeth bar (2) of chromium plating is made with 25 * 5 band steels, and both sides are the helical teeth shape, is connected with locking pressure plate (1) electric welding.Be equipped with three in the lock body (14) and mould the letter disk (6) that iron is composited, the password letter disk that kirsite dish core (7) is formed this lock.Load onto wear-resistant plastic lock core (3), two ends are formed lock body with fixed cover (4), (5) with it.Fixed bar (8) is made with 25 * 5 band steels, be connected with base (9) electric welding, by screw (10), locknut (11) lock body is fixed on valve seat (16) appropriate location, again locking pressure plate (1) is fastened valve screw (15) head, helical teeth bar (2) pushes lock body (14), then password is pulled out unrest, locking finishes.As long as password is just pulled out, extract helical teeth bar (2) out during unlatching, throw off locking pressure plate (1) and get final product.

This lock interchangeable password is extracted helical teeth bar (2) out, tightening pin (12), and trip spring structure (13) unloads fixed jacket (5), then three letter disks (6) is also unloaded.According to the password that redefines, letter disk is adjusted the position, load onto dish core (7), load onto fixed jacket (5), push helical teeth bar (2) again, pin (12) is with fixed jacket lock jail, the password adjustment finishes, and can lock, open according to new password later on, has realized the purpose of transposing password.

Claims

1. adjustable number formula valve coded lock that comprises lock body, locking pressure plate, fixed bar, it is characterized in that using the letter disk of moulding iron and being composited, the dish core that kirsite is pressed into, three figure place passwords formed by three number letter disks and lock core is fitted to each other complete lock body by fixed cover, lock body two ends pack into locking pressure plate, helical teeth bar, fixed bar base.

2. according to the described adjustable number formula valve coded lock of claim, it is characterized in that pinning letter disk, when unblanking with pinning, spring structure, pin withdraws from, unload fixed jacket, letter disk, thus letter disk can adjust the position and form new password, finish the action of changing password.

3. adjustable number formula valve coded lock according to claim 1 is characterized in that the helical teeth bar with making through heat treated 25 * 5 band steels, and both sides are the helical teeth shape.
