Description

Angle key anti-tick lock head

The utility model is a lock head and a key used for assembling high-grade locks such as safes, cash safes, money cabinets and luxury cars, and belongs to the category of non-electronic locks.

Xiaolan Town, Zhongshan City, China Dadong Metal Electrical Appliance Parts Factory applied for a utility model patent "An anti-tear lock" on July 7, 1999, and the patent number is 99236547.3. The utility model provides a novel lockset with good anti-dialing performance, low mutual opening rate, and difficult imitation of keys. However, the utility model patent still has certain weaknesses in its structure. (1) The spring installed on the anti-dialing plug-in unit expands outwards, which increases the wear and tear between the lock cylinder and the tapered end and reduces the durability of the lockset. (2) The anti-dialing plug-in unit enters the pin hole of the angle flange pin by the side pressure of the draw-in groove on the inner wall of the lock head. That is to say, at any time and under any circumstances, the pressure on the side of the rotating lock cylinder will be generated at any time, which correspondingly reduces the reliability of anti-dialing.

The purpose of this utility model is to provide an angle key anti-removal lock head, thereby solving the two problems in the above structure, improving the durability and anti-removal reliability of the lock, and making the product more perfect.

The utility model is improved on the basis of "a kind of anti-dialing lock head". The first step is to transform the anti-dialing plug-in with several cylinders and holes for placing springs on the lower end of the original cuboid into an anti-dialing insert on the top of the cuboid. The notch has several conical pins at the lower end of one side, and the hole for placing the spring is removed. The second step is to change the cylindrical hole on the side of the cylinder-shaped angle flange slingshot into a conical hole to match with some conical pins on the anti-dialing insert; the top of the angle flange slingshot has a cylindrical pin. Therefore, the utility model continues to use the angle flange marble, and the angle flange that cooperates with the angle key tooth flower is arranged on the angle flange marble, and the angle between the angle flange and the angle key in and out direction is greater than 0°, and the angle flange protrudes along the angle. The edge marbles are randomly distributed, and with the angle arrangement, the key tooth flower matching the angle flange can also be processed into an angle key. The 3rd step is to open a draw-in groove on the original lock head inner wall, and have a triangular or circular positioning groove or hole again on the corresponding orientation of the original draw-in groove. At the same time, there is a cylindrical positioning ball hole in the corresponding direction of the lock cylinder, and the force spring and steel ball are placed in the round hole, and the steel ball can fall into the triangular or circular positioning groove dug on the inner wall of the lock head. .

The advantages of the utility model are obvious: (1) the structure is more reasonable, the assembly is simple and easy, the operation is free, safe and reliable. (2) The structural change greatly reduces the frictional force between the lock cylinder and the lock end, and improves the durability of the entire lockset. (3) Further improve the reliability of anti-dipping locks, and the products are more perfect.

Further set forth the structure of the present utility model according to accompanying drawing below.

形卡槽9，在卡槽9的对应方位上开有三角形或圆形定位槽14；在锁芯1外壁开有一个圆柱形定位槽孔15，在定位槽孔15内放置加力弹簧16和钢珠17。它的第四个特点是在锁芯3的前端连接有防钻钢条18。According to the accompanying drawings, we can know that the anti-dialing lock head of the angle key is composed of a key 1, a lock head 2 and a lock cylinder 3, etc. Its first structural feature is a cuboid with a notch 5 on one side and a spring in the notch 5 8. The anti-dialing insert 10 with several conical pins 11 at the lower end of one side is embedded in one side of the lock cylinder 3, and the cylindrical angled flange pin 4 is embedded in the cylindrical pin at an angle of 90° with the anti-dialing insert 10 In the hole 6, there is a conical hole 12 on the side of the angle flange pin 4, and a cylindrical pin 13 is arranged on the top, and the top also can be flat-topped. Its second structural feature is that an angle key 1 is connected in the angle key groove 7 facing the cylindrical pin hole on the lock core 3, and the angle key 1 cooperates with the angle flange pin pin 4. Its third structural feature is that the inner wall of the lock head 2 has a

Shaped card slot 9 has a triangular or circular positioning slot 14 on the corresponding orientation of the card slot 9; a cylindrical positioning slot 15 is arranged on the outer wall of the lock core 1, and a force spring 16 and a force spring 16 are placed in the positioning slot 15. steel ball17. Its 4th feature is that the front end of lock core 3 is connected with anti-drilling steel bar 18.

The utility model emphatically solves two problems existing in the structure of "a kind of anti-dialing lock head". In our actual operation, when the angle key matched with the lock cylinder is inserted, the angle flange marble will be closely matched with the angle teeth of the key, and the up and down, left and right will be stacked in place, and the hole and the taper pin will prevent dialing. Alignment, the inward force of the spring on the anti-dialing plug-in makes the anti-dialing plug-in automatically inserted into the angle flange pin, and the upper end surface of the anti-dialing plug-in leaves the lock head slot, so that the lock can be rotated, that is, opened or unlocked; otherwise, when the angle When the key is pulled out of the lock cylinder, the relationship between the angle flange pins and the key angle, the angle flange pins rotate freely left and right, and the springs on the irregular angle flange pins are pressed down. At this time, the angle flange pins on the side Due to the relationship between the inclination of the conical hole and the force of the spring, the anti-dialing insert is pushed away from the conical hole, and the upper end surface of the anti-dialing insert enters the slot of the lock head to realize the locking function, and the lock cannot be rotated at this time , that is, the lock cannot be opened. In addition, the anti-dialing plug-in, the key structural part of the utility model, moves by the inward force of the spring to naturally press into the conical hole of the angled flange marble to reset, so that the lock cylinder can rotate. But after the key is taken out, the anti-dialing insert breaks away from the angle flange pins, and these angle flange pins are scattered and inconsistent, and any steel sheet or "master key" cannot open the lockset. Therefore, the lockset has excellent anti-removal performance and extremely low mutual opening rate, and is a high-grade lockset for anti-theft and anti-disclosure.
