technical field

The utility model relates to a combination lock technology, in particular to a code adjustment structure of a combination lock.

Background technique

The combination lock has a combination wheel, a code adjustment wheel and a code adjustment block. The operator can push the code adjustment block to drive the code adjustment wheel to move, so that the code adjustment wheel and the code adjustment wheel are disconnected and connected, and then the code can be adjusted. In the process of adjusting the cipher in the prior art, the operator must hold down the code adjustment block all the way to keep the code adjustment wheel from being connected with the cipher wheel, which makes the operation inconvenient. If the operator accidentally relaxes the code adjustment block during the code adjustment process, the code adjustment wheel and the code wheel will re-form a cooperative connection (the code adjustment wheel and the code wheel are linked), resulting in the adjusted code not being a substantially effective code. That is, the adjustment password becomes invalid.

Referring to FIG. 1 , when there is no need to adjust the password, the code adjustment wheel 32 tends to move downward under the thrust of the spring 4 (not shown in FIG. 1 ). The slider 22 of the code adjustment block 2 is limited by the arc surface 113 (see FIG. 5 ) at the lower end of the chute 112 , and keeps against the lower end surface of the code adjustment wheel 32 at the lowermost end. At this time, the plug 321 of the code adjustment wheel 32 is located in the slot 331 of the code wheel 33 , that is, the code code wheel 32 and the code wheel 33 are cooperatively connected, and the code wheel 33 can drive the code code wheel 32 to rotate around the wheel shaft 31 .

The code adjustment process of the combination code code adjustment structure provided by this embodiment:

Before adjusting the code, the code wheel 33 needs to be dialed until the code is correct, that is, the code adjustment wheel 32 is rotated until its limit groove 322 is aligned with the limit block 312 of the wheel shaft 31 . At this time, the code adjustment wheel 32 can move along the length direction of the wheel shaft 31 . Push the operating end 211 to move the code adjustment block 2 upwards (upward in FIG. 1 ), thereby driving the code adjustment block 2 to move upward, so that the insertion block 321 of the code adjustment wheel 32 is separated from the slot 331 of the code wheel 33, that is, Release the matching connection between the coding wheel 32 and the password wheel 33 . At this time, swing the code block 2 around the central axis B, so that the operating end 211 swings to enter the blocking notch 12, and the operating end 211 is attached to the stop surface 122 (as shown in Figures 6 and 7), so that the blocking notch 12 Block the coding block 2, so that the coding block 2 cannot be moved downward (to the bottom of Figure 1) to reset. At this time, the force-bearing surface 231 (see FIG. 3 ) is attached to the lower end surface of the code adjustment wheel 32 , and the side of the limit protrusion 232 is abutted by the side of the code adjustment wheel 32 .

The active force of the code adjustment wheel 32 (the thrust of the spring 4 ) mainly acts on the bearing surface 231 . Since the holding portion 23 is located on the side where the blocking notch 12 is located, the force acting on the bearing surface 231 is transformed into the pressure of the operating end 211 against the stop surface 122 . The pressure increases the coefficient of friction between the operation end 211 and the stop surface 122 , so that the operation end 211 is effectively attached to the stop surface 122 . 7, there is a gap between the right side of the code adjustment block 2 and the inner wall of the channel 11, and the side of the limit protrusion 232 is pressed by the side of the code adjustment wheel 32, so that the code adjustment block 2 will not move to the right, so that The operating end 211 is stably held in the blocking notch 12 .

At this time, the operator can turn the password wheel 33 to adjust the password. When the code is adjusted, the operating end 211 is moved to move the operating end 211 out of the blocking notch 12 . Then, the modulation block body 21 is swung until its central axis is parallel to the extending direction of the channel 11 . At this time, under the action of the spring 4 , the code adjustment wheel 32 pushes the code adjustment block 2 to move downward until the cylindrical surface of the slider 22 abuts against the arc surface 113 at the lower end of the chute 112 . At this time, the insert block 321 of the code adjustment wheel 32 enters the slot 331 of the code wheel 33, and the two are matched and connected again to complete the code adjustment operation.

The included angle between the stop surface 122 and the extending direction of the channel 11 is 50°, so that the size of the part where the operating end 211 enters the blocking notch 12 is suitable, and the effective friction force is formed between the operating end 211 and the stop surface 122, so that The blocking notch 12 can block the coding block 2 more effectively.

The cylindrical surface at the top of the slider 22 exceeds the upper end of the adjustment block body 21, and the cylindrical surface is in contact with the end surface of the adjustment wheel 3, and the bearing surface 231 is tangent to the cylindrical surface at the top of the slider 22, so that the swing of the slider 22 is smooth , smooth.
