Detailed Description

Please refer to fig. 1 to 14, which are a structure diagram and a structure diagram of each component of the present utility model. As shown in the figure, the utility model comprises a shell A, a square bolt B, a lock core rotating shaft C, a handle rotating shaft D, a lock bolt control unit 1 and a reinforced triangular bolt unit 2, wherein the square bolt B, the lock core rotating shaft C and the handle rotating shaft D are arranged on the shell A; the lock plunger control unit 1 at least comprises a self-rotating plate 11, a first pushing plate 12, a second pushing plate 13, a butterfly plate 14, a first spring 15, a second spring 16, a third spring 17, a press button 18, an arc-shaped braking piece 19 and other elements. The self-axis rotary piece 11 is arranged between the square lock tongue B and the lock bolt control unit 1 below, is continuously bent, is provided with a fixing hole 111 for fixing to the casing a at the center, and is provided with a supporting part 112 at the lower end.

The first pushing piece 12 is disposed at one side of the handle rotation axis D, and is provided with a substantially L-shaped piece body, and a protruding point 121 is disposed at the rear.

The second pushing piece 13 is arranged below the first pushing piece 12, and one side of the second pushing piece is provided with a notch 131.

The butterfly piece 14 is disposed between the first pushing piece 12 and the second pushing piece 13, and has a fixing hole 141 for fixing to the casing a.

The first spring 15 includes a ring portion 151 to be fixed to the positioning column A1 of the housing a, and an upper holder 152 and a lower holder 153 extending from the ring portion 151. The upper supporting member 151 is supported by the second pushing plate 13, and the lower supporting member 153 is supported by the lower edge wall surface of the casing a.

The second spring 16 is provided below the butterfly piece 14, and includes a loop portion 161 fixed to the casing a, and a clip portion 162 extending from the loop portion 161 and having a substantially twisted shape.

The third spring 17 is provided below the butterfly piece 14, and includes a loop portion 171 fixed to the casing a, and a fastening portion 172 extending from the loop portion 171 and having a substantially continuous bent shape.

The reinforced triangular bolt unit 2 comprises a lock 21, a rod 22 pivotally connected to the lock 21, a reinforcing ring 23 sleeved on the rod 22, and a reinforcing screw 24 locked to the lock 21 and the rod 22.

Wherein, the lock head 21 is provided with a caulking groove 211, and a positioning hole 212 is arranged on the caulking groove 211; the stem 22 has a pivot portion 221 at one end, and a fixing hole 222 is formed in the pivot portion 221. When assembling, after the reinforcing ring 23 is sleeved on the pin joint part 221 of the rod column 22, the pin joint part 221 of the rod column 22 is sleeved on the caulking groove 211 of the lock head 21, and then the reinforcing screw 24 is locked in through the positioning hole 212 of the lock head 21, so that the reinforcing screw passes through the fixing hole 222 of the rod column 22, and the rod column 22 is locked and fixed on the lock head 21, so that the triangular lock tongue unit 2 achieves the reinforcing effect through the change of shape and structure.

By combining the elements, the multifunctional reinforced lock structure is formed. When the lock core rotating shaft C rotates, the shaft rotating piece 11 rotates to the closing position, the second pushing piece 13 does not act because the butterfly piece 14 pushes to the neutral position, and then the second pushing piece is used as a blocking piece of the handle rotating shaft D, so that the double fastening function is formed, and the protection and anti-theft effects of the lock are improved. And; the reinforced triangle bolt unit 2 can be combined by the lock head 21, the rod column 22, the reinforced ring 23 and the reinforced screw 24, so that the reinforced triangle bolt unit 2 can achieve the reinforcing effect through the change of shape and structure, and the lockset is further reinforced.

Please refer to fig. 15 and 16, which are operation status diagrams of the present utility model. As shown in the figure, when the square lock tongue B is pushed out by the rotation of the upper lock core shaft C, the self-rotating plate 11 is pushed, and the supporting part 112 below the self-rotating plate 11 drives the first push plate 12, so that the first push plate 12 pushes the handle shaft D, and the handle shaft D cannot rotate. Since the first spring 15 is disposed below the second push plate 13 on the positioning post A1, the first spring 15 can be used as a buffer-reducing element. When the square bolt B is rotated by the upper lock core rotation shaft C, the second push plate 13 is moved back from the shaft rotation plate 11 to the open position, and the second spring 16 and the third spring 17 are provided to spring back to the open position, so that the first push plate 12 is withdrawn from the handle rotation shaft D, and the handle rotation shaft D can be rotated freely. Therefore, the lock can achieve the double fastening effect, and the protection and anti-theft effects of the lock are improved.

When the arc brake piece 19 is rotated at the same time by pushing the dynamic pressure button 18, the arc brake piece 19 pushes the second push piece 13 through the second spring 16 to enable the first push piece 12 to push the handle rotating shaft D, so that the handle rotating shaft D cannot rotate, and meanwhile, the butterfly disk 14 blocks the first push piece 12, because the first push piece 12 is provided with an angled protruding point 121 at the rear, when the arc brake piece 19 is pushed to a closed position, the push rod and the shape on the arc brake piece 19 can have double fastening effect with the time difference of the two positions at the rear of the first push piece 12. So that when the upper square bolt B rotates, the position from the pivoting piece 11 to the closing is not moved to the disc 14, and thus the square bolt B cannot control the opening and closing actions of the lower first push piece 12.

The above description is only a preferred embodiment of the present utility model, and is not intended to limit the utility model, so that any equivalent substitutions and modifications can be made by those skilled in the art without departing from the scope of the present utility model.
