In the description of the present application, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated.

1-2, The present application discloses a hidden security lock comprising

A base 1; the base 1 is provided with a first cavity 1a and a second cavity 1b, the first cavity 1a is communicated with the base 1 along the extending direction of the base 1, and the second cavity 1b is vertical to the first cavity 1a and is communicated with the first cavity 1 a; preferably, the base 1 is made of copper or aluminum, has a long strip shape and a thickness much smaller than its length, and is machined to form the first cavity 1a and the second cavity 1b by removing the material by machining.

A plug 2 and a drive shaft 3; the bolt 2 is inserted into the first cavity 1a, the driving shaft 3 is inserted into the second cavity 1b, and the driving shaft 3 is inserted into the second cavity 1b to drive the bolt 2 to move along the first cavity 1 a; preferably, teeth 21 are distributed along the length direction of the latch 2, the driving shaft 3 is a gear shaft, and the driving shaft 3 is meshed with the latch 2 after being inserted into the second cavity 1 b. The bolt 2 can be formed by die casting metal, or can be obtained by other casting methods, and can be obtained by shaping the bolt by machining. Similarly, the driving shaft 3 is formed by casting or by bar hobbing to obtain teeth, so as to form a gear shaft, and then the sizes and positions of the first cavity and the second cavity are appropriately adjusted according to the sizes of the bolt 2 and the gear shaft, so that the bolt 2 and the driving shaft 3 can be meshed after being respectively inserted into the first cavity and the second cavity, and the bolt 2 can be driven to linearly reciprocate by rotating the driving shaft 3 in the forward direction or the reverse direction (see the action principle of a gear-rack structure).

The lock cylinder also comprises a lock cylinder 4 and a lock cylinder seat 5; the lock cylinder 4 is arranged in the lock cylinder seat 5, and the lock cylinder 4 is connected with the driving shaft 3; specifically, the driving shaft 3 is embedded into a shaft hole formed in the lock cylinder 4, preferably, one end, connected with the lock cylinder 4, of the driving shaft 3 is a spline shaft, and the shaft hole is a spline hole corresponding to the spline shaft. The key 10 can be turned to drive the lock cylinder 4 to rotate only when the key 10 is inserted into the lock cylinder, and then the driving shaft 3 is driven to rotate, so that the bolt 2 is driven to linearly reciprocate in the first cavity.

In order to realize the installation of the safety lock, the embodiment also comprises a screw 9, and the frame 11 of the door and window is provided with an installation groove 111, for example, the hollow part of the aluminum profile of the aluminum alloy door and window can be used as the installation groove 111, and the safety lock part can be preloaded in the installation groove during the assembly.
