Problems solved by technology

In order to improve the safety of mechanical pin locks, the usual practice is to increase the number of pin groups and change the shape of the key cross section. For example, the current key cross section has "one" shape, "Y" shape, "ten" shape, crescent shape and other shapes. , the number of tumbler groups is 4-12 groups, which on the one hand increases the number of parts of the pin lock and the difficulty of processing and assembling, and increases the processing cost. On the other hand, due to the working principle of the pin lock, its safety is not high, which is very Easy to be opened by criminals

Embodiment 1

[0018] Such as figure 1 , 2 As shown in, 3, and 4, a rotatable lock cylinder 1 is installed in the lock body 3. The lock cylinder is a "T"-shaped stepped shaft. The upper cylinder of the "T"-shaped stepped shaft is provided with a key hole 14 and The large cylinder on the upper part of the "T"-shaped stepped shaft matches the stepped hole on the lock body. The lower end of the small cylinder of the "T"-shaped stepped shaft protrudes from the lower end of the lock body, and is positioned axially by the axial positioning device 6. The axial positioning device can adopt the prior art shaft spring retainer or The lower end of the T"-shaped stepped shaft is fixed with a washer and a fixing screw, so that the upper part of the lock cylinder passes through the stepped hole, and the lower part is passed through the shaft spring ring or washer and the fixing screw, which will serve as the "T"-shaped step of the lock cylinder The shaft is fixed in the lock body along the axial direction....

Embodiment 2

[0023] Such as Figure 5 As shown, on the basis of Embodiment 1, the structure of the protrusions of the internal coding has been changed, and the rest is the same as Embodiment 1.

[0024] The changes are explained as follows. The protrusion of the inner code is composed of a through hole opened in the radial direction of the small cylinder, a pin shaft 4-1 installed in the through hole, and a compression spring 15 sleeved on the pin shaft. A small cylinder extends from the left end of the pin shaft. There is an annular boss on the outer circle of the surface, and the compression spring 15 is sleeved on the upper pin shaft between the annular boss and the small cylinder, and on the inner wall of the annular cavity 5 on the lock body, and the pin The corresponding position of the end face of the left end of the shaft is provided with a recess that matches the end face of the pin shaft. When the special key is inserted and turned, the left side of the pin will move to the right ...

Abstract

The invention relates to a lock, especially a new type of pinless mechanical lock and a special key. The lock includes a lock body, a lock core installed in the lock body and a lock core guard, and is characterized in that the lock core is a "T" shaped ladder There is a key hole on the large cylinder in the "T"-shaped stepped shaft, and the large cylinder on the "T"-shaped stepped shaft matches the stepped hole on the lock body, and the small "T"-shaped stepped shaft The lower end of the cylinder protrudes from the lower end of the lock body and is positioned by an axial positioning device. The annular cavity formed between the small cylinder and the lock body is on the inner wall of the lock body along the axial direction of the annular cavity. There are more than 2 outer coded protrusions arranged, and more than 2 inner coded protrusions are distributed on the small cylinder of the "T" shaped stepped shaft in the annular cavity, and the key blocking plate is installed on the "T" In the large cylinder in the shaped stepped shaft and the stepped hole on the lock body matched with the large cylinder. The lock has the characteristics of few parts, low production cost, good safety and the like.

Description

Technical field [0001] The invention relates to a lock, in particular to a new type of non-ball mechanical lock and a special key. Background technique [0002] At present, all mechanical locks opened with a key are composed of a lock body and a rotatable lock cylinder installed in the body. A key hole for inserting the key is opened on the lock cylinder, and multiple sets of marbles are installed in the lock cylinder and the lock body. And spring, each set of marbles is composed of two marbles of different lengths. On one side of the lock body, a lead seal is used to seal the pin and spring in the lock core and the lock body. The corresponding key is opened with a corresponding pit. When the key is inserted into the key hole, the pin contacts the corresponding pit. The ball moves along the axis of the ball to different positions, so that the contact surface of the lock cylinder and two of the multiple sets of pins installed in the lock body is exactly on the contact surface bet...
