Detailed Description

The invention is further described with reference to the following examples.

Referring to fig. 1, the code adjusting structure of the combination lock provided by the embodiment includes a housing 1 and a code adjusting block 2 located in the housing 1. The combination lock comprises a combination assembly located within the housing 1.

Referring to fig. 2, the combination assembly includes an axle 31, a combination wheel 32, and a combination wheel 33. The code adjusting wheel 32 is sleeved outside the wheel shaft 31, and the code adjusting wheel 33 is sleeved outside the code adjusting wheel 32. The code wheel 32 is axially movable relative to the code wheel 33. A spring 4 is arranged between the head 311 of the wheel shaft 31 and the code wheel 32 close to the head 311, the spring 4 is sleeved outside the wheel shaft 31, and the spring 4 is in a compressed state.

Referring to fig. 3, the code adjusting block 2 includes an integrally formed code adjusting block body 21 and a sliding block 22. The code adjusting block body 21 and the sliding block 22 are both cylindrical (the code adjusting block body 21 and the sliding block 22 are penetrated). The slide block 22 is positioned at the upper end of the code adjusting block body 21. The cylindrical surface of the top of the sliding block 22 exceeds the upper end of the code adjusting block body 21. Referring to fig. 1, the lower end surface of the lowermost code wheel 32 is in contact with the cylindrical surface of the slider 22. The lower end of the modulation block body 21 is an operation end 211. The operating end 211 is provided with a dial hole 212, and the operating end 211 can be dialed by inserting a thin tip into the dial hole 212.

Referring to fig. 4, a channel 11 is formed in the inner wall of the housing 1, and the code adjusting block 2 is movably arranged in the channel 11 in a penetrating manner (see fig. 1). Referring to fig. 5, the hole formed through the housing 1 by the passage 11 is an operation hole 111. The wall of the channel 11 is provided with a sliding groove 112. The cylindrical end of the slider 22 is disposed in the sliding slot 112, and the central axis B of the slider 22 is perpendicular to the bottom wall of the sliding slot 112. The cylindrical surface of the slider 22 slidably contacts the side wall of the slide groove 112. The side walls of the upper and lower ends of the sliding chute 112 are arc surfaces 113, and the arc surfaces 113 correspond to the cylindrical surface of the sliding block 22.

Referring to fig. 1, when the code is not required to be adjusted, the code wheel 32 tends to move downward under the urging force of the spring 4 (not shown in fig. 1). The slider 22 of the code adjusting block 2 is restrained by a lower end arc surface 113 (see fig. 5) of the slide groove 112 and is held against a lower end surface of the code adjusting wheel 32 located at the lowermost end. At this time, the insertion block 321 of the code wheel 32 is located in the insertion slot 331 of the code wheel 33, that is, the code wheel 32 and the code wheel 33 are connected in a matching manner, and the code wheel 33 can drive the code wheel 32 to rotate around the axle 31. At this time, the operation end 211 of the code adjusting block 2 is flush with the opening of the operation hole 111.

Referring to fig. 5, the inner wall of the channel 11 is provided with a blocking notch 12 as a blocking structure. The blocking notch 12 is provided with a concave arc surface 121 and a stop surface 122. The concave cambered surface 121 corresponds to the shape of the cylindrical surface of the code adjusting block body 21. The stop surface 122 is a plane, and the angle between the stop surface 122 and the extending direction of the channel 11 (i.e. the pushed direction of the code adjusting block 2) is 50 °.

Referring to fig. 3, the code adjusting block 2 further includes a holding portion 23, and the holding portion 23 is integrally formed with the code adjusting block body 21. The holding portion 23 is located on the side of the code adjusting block body 21 close to the catching notch 12 (see also fig. 6 and 7), and the holding portion 23 is located on the side of the code adjusting block body 21 close to the code adjusting wheel 32. The holding part 23 is provided with a bearing surface 231, and the bearing surface 231 is tangent with the cylindrical surface at the top of the slide block 22. One end of the holding part 23 far away from the adjusting block body 21 is provided with a limiting protrusion 232.

The regulation password process of the password lock code regulation structure provided by the embodiment is as follows:

before adjusting the password, the password wheel 33 needs to be dialed to be correct, that is, the password wheel 32 is rotated until the limiting groove 322 is aligned with the limiting block 312 of the wheel shaft 31. At this time, the code wheel 32 can move along the longitudinal direction of the wheel shaft 31. The operating end 211 is pushed to move the code adjusting block 2 upwards (towards the upper side of fig. 1), so as to drive the code adjusting block 2 to move upwards, and the insertion block 321 of the code adjusting wheel 32 is separated from the insertion slot 331 of the password wheel 33, i.e. the matching connection between the code adjusting wheel 32 and the password wheel 33 is released. At this time, the adjusting block 2 is swung around the central axis B, the operating end 211 is swung to enter the blocking notch 12, and the operating end 211 is attached to the stopper surface 122 (as shown in fig. 6 and 7), so that the blocking notch 12 blocks the adjusting block 2, and the adjusting block 2 cannot be moved downward (downward in fig. 1) to be reset. At this time, the bearing surface 231 (see fig. 3) is attached to the lower end surface of the code wheel 32, and the side surface of the limit protrusion 232 is abutted by the side surface of the code wheel 32.

The urging force of the encoder wheel 32 (the urging force 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 converted into a pressing force of the operating end 211 against the stop surface 122. This pressure increases the coefficient of friction of the operating end 211 against the stop surface 122, thereby effectively seating the operating end 211 against the stop surface 122. Referring to fig. 7, a gap exists between the right side of the code adjusting block 2 and the inner wall of the channel 11, and the side surface of the limiting protrusion 232 is abutted by the side surface of the code adjusting wheel 32, so that the code adjusting block 2 cannot move rightwards, and the operating end 211 is stably kept in the blocking notch 12.

At this time, the operator can rotate the code wheel 33 to adjust the code. After the password is adjusted, the operation end 211 is shifted, so that the operation end 211 is moved out of the blocking notch 12. Then, the code adjusting block body 21 is swung until its central axis is parallel to the extending direction of the passage 11. At this time, the code adjusting wheel 32 pushes the code adjusting block 2 to move downwards under the action of the spring 4 until the cylindrical surface of the slide block 22 abuts against the arc surface 113 at the lower end of the sliding chute 112. At this time, the insertion block 321 of the code adjusting wheel 32 enters the insertion slot 331 of the code wheel 33, and the two are matched and connected again to complete the code adjusting operation.

The angle between the stop surface 122 and the extending direction of the channel 11 is 50 °, so that the portion of the operation end 211 entering the blocking notch 12 is suitable in size, and the operation end 211 and the stop surface 122 form an effective friction force, so that the blocking notch 12 can block the adjusting block 2 more effectively.

The cylindrical surface at the top of the sliding block 22 exceeds the upper end of the code adjusting block body 21, the cylindrical surface is in contact with the end surface of the code adjusting wheel 3, and the bearing surface 231 is tangent to the cylindrical surface at the top of the sliding block 22, so that the sliding block 22 can swing smoothly.
