Detailed Description

The invention is further described below in connection with the following detailed description.

Referring to fig. 1 to 3, the split coded lock provided by the invention comprises a fixed shell 2 and a swinging shell 3, wherein the fixed shell 2 is arranged on a first opening and closing side 1 of a case. Referring to fig. 2 and 3, the swing case 3 is hinged to the fixed case 2, and the fixed case 2 is provided with a receiving chamber (not shown) capable of receiving the swing case 3.

In combination with fig. 4 and 5, a password component is arranged in the swinging shell 3, the password component comprises a wheel shaft, three password adjusting wheels 4 are sleeved outside the wheel shaft, and a password wheel is sleeved outside each password adjusting wheel 4. The combination of the password components can be found in chinese patent application 201610357962.1. The side wall of each code wheel 4 is provided with a containing notch 41. The swinging shell 3 is internally provided with a swinging plate 5, the swinging plate 5 is provided with three protruding parts 51, and each protruding part 51 is matched with one code adjusting wheel 4. The inner wall of the second opening and closing side 9 of the case is provided with a catch 91. The swing case 3 has an insertion column 31. In the locked state of the combination lock, the insertion post 31 is inserted into the lock catch 91, as shown in fig. 3.

Referring to fig. 4 and 5, two anti-sway sliders 14 are provided inside the sway case 3, and the anti-sway sliders 14 are slidably connected to the sway case 3. The swing piece 5 has a slip stopper 52, and the slip stopper 52 is located between the two swing stopper blocks 14. In the locked state of the combination lock, the anti-slip portion 52 is held against the anti-sway slide block 14 (see fig. 7), so that the anti-sway slide block 14 cannot slip inward, so that the anti-sway slide block 14 is kept partially exposed to the sway case 3 (as shown in fig. 3), the anti-sway slide block 14 is exposed to the inner wall of the accommodation cavity of the fixed case 2, which is partially stuck to the sway case 3, so that the sway case 3 cannot sway, so that the insertion column 31 of the sway case 3 is kept inserted into the lock catch 91, and the combination lock is in the locked state. The anti-swing slider 14 is in a Z shape, is compactly arranged in the swing casing 3, and can save the internal space of the swing casing 3 while playing an effective locking role.

Referring to fig. 6, a first elastic member and two second elastic members are disposed in the swing housing 3, the first elastic member is a first spring 6, the second elastic member is a second spring 7, and lower ends of the first spring 6 and the second spring 7 are both abutted against the bottom wall of the swing housing 3. The protruding portion 51 of the swing piece 5 is located between the first spring 6 and the second spring 7 (see fig. 5). The bottom wall of the swing case 3 is slidably provided with a drive pin 8 (see fig. 6), the drive pin 8 passes through the first spring 6, the first spring 6 abuts the drive pin 8 against an upper end contact slip stopper 52 (see fig. 5) of the drive pin 8, and thereby the drive pin 8 and the second spring 7 are jointly abutted against the swing piece 5 so that the protruding portion 51 is kept in contact with the side wall of the code wheel 4 (see fig. 7). When the combination wheel is dialed to the correct combination, that is, each protruding part 51 is aligned with the corresponding accommodating notch 41, at this time, the first spring 6 pushes the swinging piece 5 to swing until each protruding part 51 falls into the corresponding accommodating notch 41, during this process, the first spring 6 pushes the swinging piece 5 to swing until the sliding stop 52 does not abut against the sliding stop block 14 (see fig. 5), so that the sliding stop block 14 can slide inwards, and the part of the sliding stop block 14 exposed out of the swinging shell 3 slides into the swinging shell 3, at this time, the operator can swing the swinging shell 3, and the insertion column 31 is pulled out from the lock catch 91, so as to unlock.

Referring to fig. 2 and 3, a lock cylinder assembly is provided in the fixed housing 2, and the lock cylinder assembly includes a lock cylinder 12 and a transmission block 13, and the lock cylinder 12 and the transmission block 13 are engaged with each other so that the lock cylinder 12 and the transmission block 13 can be rotated synchronously. Referring to fig. 7 and 8, a transmission rod 10 is provided in the fixed housing 2, the transmission rod 10 is rotatably connected to the fixed housing 2, and the transmission rod 10 has a first transmission protrusion 101 and a second transmission protrusion 102. When the combination is not dialed to the correct combination, as shown in fig. 7, the receiving notch 41 is not aligned with the tab 51, and the lock cylinder 12 (not shown in fig. 7) is rotated to rotate the drive block 13 in direction a. The driving block 13 has a toggle portion 131 (refer to fig. 9), and during the rotation of the driving block 13, the toggle portion 131 pushes the first driving protrusion 101 to swing along the direction B by a certain angle (refer to fig. 7), so that the second driving protrusion 102 swings, and thus the second driving protrusion 102 pushes the driving pin 8 to slide upwards to the state shown in fig. 8, so that the driving pin 8 pushes the anti-sliding portion 52 to the state that the anti-sliding portion 52 does not abut against the anti-swing slider 14, and at this time, the anti-swing slider 14 can slide inwards, so that the part of the anti-swing slider 14 exposed to the swing case 3 slides into the swing case 3, so that the swing case 3 can swing, to unlock. The second spring 7 (not shown in fig. 8) is further compressed during the pushing of the slip stopper 52 by the driving pin 8.

The swing piece 5 is jointly abutted by the transmission pin 8 and the second spring 7, and the protruding part 51 of the swing piece 5 is positioned between the first spring 6 and the second spring 7, so that the swing piece 5 can swing in different directions according to a password unlocking mode or a lock core unlocking mode, the movement mode is flexible, the design is exquisite, and the internal structure of the coded lock is compact.

Referring to fig. 4 and 10, the stationary case 2 is provided with an opening button 11 as an opening member, and the opening button 11 is slidably connected to the stationary case 2. Two transmission pieces 15 are arranged in the fixed shell 2, the transmission pieces 15 are slidably connected with the fixed shell 2, and the transmission pieces 15 are provided with transmission grooves 151. The opening button 11 is provided with a pin hole 111, and the driving piece 15 is connected to the opening button 11 by a driving pin (not shown) passing through the pin hole 111 and the driving groove 151, and a driving pin center line F (F') in fig. 10 corresponds to the driving pin center line F in fig. 4. Referring to fig. 10, pressing the opening button 11 downward can drive the two transmission pieces 15 to slide inwards in opposite directions, so that the transmission piece 15 drives the anti-swing slider 14 to slide inwards until the part of the anti-swing slider 14 exposed out of the swing case 3 slides into the swing case 3, so that the swing case 3 can be swung to realize unlocking.

Wherein the drawings are for illustrative purposes only and are shown in schematic, non-physical, and not intended to be limiting of the present patent; for the purpose of better illustrating embodiments of the invention, certain elements of the drawings may be omitted, enlarged or reduced and do not represent the size of the actual product; it will be appreciated by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted.
