Abstract

This invention is the invention of a single drawer system with a combination of keys. In which the system can open one drawer at a time, the principle of limiting the travel distance is designed The difference of the R2 and R1 distance of part number 14 is equal to the Y distance of part-number 10, then the parts are assembled as shown in Figure 5, where part number 8 is firmly attached to the shape steel. C, number 7, then part number 10 is inserted in the part - number 8 horizontally, and part number 11 is inserted in the groove of the part. No. 10 and spring press the No. 11 part to move down when no force is applied. Parts No. 11,12,13 and 15 are assembled and moved up and down within the No. 7 C-shaped steel. 17 Hold down all parts from falling out of the C-shaped steel, then take this set of the drawer opening system one by one together with the key set as shown in Figure 1 to get a key set. Lock for multiple drawers with a system that can open one drawer at a time.

Claims (5)

1. A set of locks for multiple drawers at the same time with a central lock system and a single drawer opening system. Which consists of padlock (1) bridge gear (2) bolt (3) bolt plate (4) bracket (5) number 3 bolt lock (6) C-shaped steel (C) (7) mechanical control plate (8) Spring (9) Sliding plate (10) Mechanism pivot (11) V-shape steel (V) (12) Movement on turtle housing (14) Turtle lock (15) Drawer attached (16) ) The end piece controller (17) is characterized by the use of the C-shaped steel lower end part controller. (C) (7) and then the wave iron (V) (12) slack the tip so that it flows freely into the C-shaped groove (7) to get the right height that the first set of turtles does not crush with. Ball bearing rail set, bottom drawer The mechanical slide plate assembly (10), the mechanical control plate (8), the mechanical spur (11) and the mechanical spring (9), the bolt (3) is connected to the bridge gear (2), mounted in the key (1) the lock. Bolt (6) secures the bolt (3) connects to the bolt plate (4) and attaches to the bracket (5). 2. Key to lock multiple drawers at the same time according to claim 1, with special characteristics Key holder can Removable and at the end of the cylinder is a rectangular shape connected to the bolt drive gear (4) that moves up-down and drives. The bridge gear (2) is connected to the bridge bolt (3) by moving in and out of the locking hole of part (8) in Figure 7. 3. A set of locks at the same time as mentioned in No. 1 or No. 2 has a distinctive tongue but Each door can be opened independently by means of a mechanical control plate (8) attached to a C-shaped steel (7) and a sliding plate. Mechanism (10) is inserted in the slider of the sliding plate (8) and the mechanism (11) is in the C-shaped groove (7) with the protruding axis in the groove of the sliding plate (10) and the wave iron. V (12) with the moving body on the t.turtle (15) and it can move up and down inside the C-shaped steel (7). The bottom part of the C-shaped steel (7) protects the internal parts of the C-shape from coming off outside and being pressed by a spring (9). 4. The combination of multiple locks referred to in any of Claims 1 to 3, where when the drawer is pulled out, the drawer part (16) moves out of the drawer, causing the lock. The turtle (14) rotates the pusher movement on the T. turtle (13) and the other parts upward move up to Y, then causes the mechanical slider (10) to move X distance horizontally and pivot. Mechanism (11) moves up within degrees. Of the sliding mechanism (10) is the distance Y to the end, making it impossible to open other drawers. Until the tongue is closed The torso (14) turns back to its original position and the spring (9) presses the previously moving part to move it. Down a distance Y in this stroke when turning the key will make the bolt (3) move into the lock slot of the plate. Mechanically controlled (8) the drawer will not open. 5. Multiple lock set as referred to in clause 1 to clause 4, any one of them is characterized by a central locking combination with a drawer opening system that can be opened individually.
