They do not indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meanings.

[0031] This embodiment provides a split-type password lock, which separates the password device and the handle. During the manufacturing process, there is no need to set the positions of various parts according to the specifications of different panels, saving design time and design costs.

[0032] like Figure 1 As shown, the split-type password lock includes a handle and a password device, wherein the password device is arranged above or below the handle, and the password device includes a password disk 1, an opening knob 2, a lock body and a password mechanism 3. The password disk 1 is connected to the password mechanism 3 to dial the password mechanism 3, and the password mechanism 3 is connected to the lock body to drive the lock body to rotate. The password mechanism 3 is arranged in the cavity formed by the opening knob 2, and the opening knob 2 can drive the password mechanism 3 to rotate as a whole to unlock or lock.

[0033] The split combination lock provided in this embodiment separates the combination mechanism from the handle, eliminating the need to adjust the placement of components according to panel specifications during manufacturing, saving design time and cost. During unlocking or locking, combination dial 1 activates combination mechanism 3, which is connected to the lock body. This allows unlocking to be achieved simply by moving combination dial 1 and opening knob 2.

[0034] Preferably, in this embodiment, Figure 2As shown, the password mechanism 3 includes a rotating shaft 31, a password wheel assembly 32, and an inner end cap 33. One end of the rotating shaft 31 is drivingly connected to the password disk 1, and the other end of the rotating shaft 31 passes through the password wheel assembly 32 and connects to the inner end cap 33. It should be noted that the opening knob 2 drives the entire password wheel assembly 32 to rotate only when the password is correct. If the password is incorrect, the opening knob 2 cannot move the password wheel assembly 32 and it rotates accordingly. The function of the rotating shaft 31 is to rotate the password wheel assembly 32 to align or scramble the password, thereby achieving the purpose of locking or unlocking.

[0035] Preferably, in this embodiment, Figure 2 and Figure 3 As shown, the opening knob 2 includes a lock gate, which in turn includes a limit gate 21 and a cylindrical pin 22. The limit gate 21 is elastically supported by the opening knob 2. When the opening knob 2 is rotated, the cylindrical pin 22 can squeeze or release the limit gate 21, causing it to come into contact with or disengage from the code wheel assembly 32. The limit gate 21 includes a working portion and a contact portion. The contact portion abuts the cylindrical pin 22 and is supported by the opening knob 2. The working portion can rotate the code wheel assembly 32 as a whole, thereby driving the lock body fixedly connected to the code wheel assembly 32. The contact portion of the limit gate 21 fits in contact with the cylindrical pin 22, preventing the cylindrical pin 22 from disengaging from the limit gate 21 during operation. A guide surface is provided at the bottom end of the working portion to allow the limit gate 21 to extend into the code wheel assembly 32.

[0036] Optionally, in order to support the limit gate 21, a support plate 23 supporting the limit gate 21 is provided in the chamber formed by the opening knob 2 in this embodiment, and the two support plates 23 are symmetrically arranged. The limit gate 21 is supported on the support plates 23 by a support spring 24, and the working part of the limit gate 21 passes between the two support plates 23 to drive the password wheel assembly 32 to rotate as a whole. Furthermore, a first groove is provided in the chamber formed by the opening knob 2, and a second groove is provided at the contact portion where the limit gate 21 contacts the cylindrical pin 22. The cylindrical pin 22 abuts against the first groove and the second groove, respectively, and the cylindrical pin 22 can be disengaged from the first groove. When the cylindrical pin 22 is clamped by the first groove and the second groove, the top surface and bottom surface of the cylindrical pin 22 respectively fit in the first groove and the second groove.

[0037] Optionally, in this embodiment, refer to Figure 2 and Figure 5 A first rotating gear 34 is mounted on one end of the rotating shaft 31. A second rotating gear 11 is fixedly mounted on the combination wheel 1. The first rotating gear 34 meshes with the second rotating gear 11. When the combination wheel 1 is rotated, the second rotating gear 11 rotates with it. The first rotating gear 34, meshing with the second rotating gear 11, then drives the rotating shaft 31 to rotate, thereby aligning or disrupting the combination wheel assembly 32.

[0038] In this embodiment, continue to refer to Figure 2 The code wheel assembly 32 includes flat washers 321, an adjustment knob 322, and a code wheel 323. The flat washers 321 and code wheel 323 are arranged in an alternating pattern. The rotating shaft 31 passes through the flat washers 321 and code wheel 323 and connects to the inner end cap 33. The code wheel 323 is provided with a slot for the limit gate 21. Specifically, the limit gate 21 extends into the slot of the code wheel 323, enabling the opening knob 2 to rotate the code wheel assembly 32 as a whole. The adjustment knob 322 includes a curved adjustment plate and an adjustment shaft. One end of the adjustment shaft is fixed to the curved adjustment plate, while the other end passes through the inner end cap 33. The inner end cap 33 is provided with a curved hole 331 for the adjustment shaft to rotate. The adjustment plate is located at the end of the rotating shaft 31 near the code disk 1. When the code device is installed, the code can be set by rotating the adjustment knob 322. When the code needs to be changed, the adjustment knob 322 is used to reset the code. This embodiment uses the combination wheel assembly of the Master lock. The specific structure of the combination wheel assembly is prior art and will not be described in detail here.

[0039] like Figure 4 As shown, the inner end cover 33 is fixedly connected to the opening knob 2 by the mounting screw 7. When the password is forgotten or the adjustment is made incorrectly during operation when unlocking, and the corresponding password cannot open the split-type combination lock, the mounting screw 7 on the inner end cover 33 can be removed to expose the combination wheel assembly 32. After finding the correct password, the screw can be tightened. It can be used repeatedly to increase the service life of the combination lock.

[0040] In order to limit the movement of the code disk 1, the code device in this embodiment further includes a limit steel ball 4 and a limit spring 5. A limit hole 25 is provided on the side wall where the opening knob 2 contacts the code disk 1. The limit spring 5 is disposed in the limit hole 25. The limit steel ball 4 abuts against the code disk 1 and the limit spring 5, respectively. Figure 5 As shown, the side wall of the combination disk 1 that contacts the opening knob 2 is circumferentially provided with a plurality of spherical grooves 12. The spherical grooves 12 cooperate with the limiting steel balls 4 to position the combination disk 1. When the combination disk 1 is rotated to align or scramble the combination, the spherical grooves 12 limit the limiting steel balls 4 to prevent the combination disk 1 from rotating.

[0041] Optionally, in this embodiment, the password device also includes a base 6, one end of the base 6 extends into the cavity formed by the opening knob 2, and the other end is fixed to the door panel. The base 6 is used to fix the password device as a whole on the door panel to ensure that the split password lock can be used normally.

[0042] The unlocking process of the split combination lock is as follows:

[0043] The user manually rotates the code disk 1, and the code disk 1 rotates the code wheel device, thereby rotating the code wheel to achieve code alignment. After the code is aligned, the code wheels overlap to form a slot for the limit gate 21 to be inserted. At this time, the opening knob 2 is turned, and the opening knob 2 is rotated to force the cylindrical pin 22 to disengage from the first groove. The cylindrical pin 22 will now press the limit gate 21 down into the slot, and then the opening knob 2 is turned. At this time, the opening knob 2 will drive the code wheel assembly 32 to rotate as a whole, thereby achieving the purpose of unlocking.

[0044] The locking process of the split password lock is as follows:

[0045] The user manually turns the opening knob 2. When the opening knob 2 is turned to the right position, the cylindrical pin 22 enters the first groove. At this time, the password disk 1 is turned to rotate the password wheel device, thereby turning the password wheel to scramble the password (i.e., scramble the password wheel), thereby achieving the purpose of locking.

[0046] This embodiment also provides a door body, including a door panel, on which is provided a split-type password lock provided in this embodiment.

[0047] Furthermore, the above are only preferred embodiments of the present invention and the technical principles employed. Those skilled in the art will appreciate that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments, and substitutions are possible for those skilled in the art without departing from the scope of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments and may include many other equivalent embodiments without departing from the scope of the present invention. The scope of the present invention is determined by the scope of the appended claims.
