[0028] The following is a combination of the appended examples of the present invention Figure 1-8 , clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.
[0029] Example:
[0030] like Figures 1 to 8As shown, the utility model discloses a folding combination lock, including a lock body and a folding assembly. The lock body includes a lock shell 1, a combination lock cylinder 21 arranged in the lock shell 1, and a male rod 25 arranged in the combination lock cylinder 21. The lock shell 1 has a combination rotation port 12 for exposing the combination lock cylinder 21. The male rod 25 can move linearly after the combination lock cylinder 21 is unlocked, and cannot be moved when the combination lock cylinder 21 is in a locked state. The combination lock cylinder 21 is a plurality of combination rings, which are rotated to select the corresponding number to unlock. In addition, the folding assembly includes a fixed section 3, a movable section 4, and a plurality of connecting sections 5 hinged between the fixed section 3 and the movable section 4. The fixed section 3 and the movable section 4 are respectively located at both ends of the combination lock cylinder 21. The connection between the fixed section 3, the movable section 4 and the movable section 4 is not much different from the prior art. The structure and coordination of the combination lock cylinder 21 and the male rod 25 are also prior art, so they are not elaborated in detail. In the present invention, the fixed section 3 is connected to one end of the lock housing 1, and a socket 11 is provided on the side wall of the lock housing 1. A locking piece 41 for inserting into the socket 11 is integrally formed on the movable section 4, wherein the male row 25 is fixedly connected to a button 24 on one end near the fixed section 3. The button 24 is used to be pressed when the password lock cylinder 21 is unlocked, thereby pushing the male row 25, and a return spring 6 for pushing the male row 25 toward the button 24 is provided on the other end of the male row 25. The male row 25 is fixedly connected to a limiting lock block 251 on one end near the return spring 6 for limiting the locking piece 41 from leaving the socket 11. The limiting lock block 251 no longer limits the locking piece 41 from leaving the socket 11 after the button 24 is pressed.
[0031] Specifically, the locking plate 41 is provided with a locking notch 411 for axial passage of the limiting locking block 251. Furthermore, the locking plate 41 also has a male rod passage slot 412 formed above the locking notch 411. The locking notch 411 is wider than the male rod passage slot 412. When the limiting locking block 251 is located within the locking notch 411, it cannot escape from the male rod passage slot 412. The male rod passage slot 412 is just wide enough to allow passage of the male rod 25. When the return spring 6 is in its initial state, the limiting locking block 251 is located within the locking notch 411, preventing the locking plate 411 from being removed from the socket 11. However, when the button 24 is pressed, the male rod 25 compresses the spring, causing the limiting locking block 251 to move away from the locking notch 411. At this point, the locking plate 41 can be removed from the socket 11 because the male rod passage slot 412 is wide enough for the male rod 25 to pass through.
[0032] Furthermore, the limiting lock block 251 is of a rectangular structure and is integrally formed on the male rod 25, which reduces the structural components of the present application, increases its manufacturing simplicity, and improves the connection strength and durability, ensuring that it is not easily damaged during long-term use, further enhancing the reliability and service life of the lock. In addition, the limiting lock block 251 is provided with an inclined surface 252 on the side facing the socket 11, and the locking piece 41 is provided with an insertion inclined surface 413 on the end away from the movable joint 4. This structure facilitates the direct insertion of the locking piece 41 into the socket when the button 24 is not pressed to push the male rod 25. The locking piece 41 cooperates with the inclined surface 252 on the limiting lock block 251 through the insertion inclined surface 413, and can push the male rod 25 to compress the spring until the male rod 25 passes through the male rod passage groove 412 and reaches the lock mouth 411. The reset spring 6 resets and pushes the limiting lock block 251 into the lock mouth 411 to form a lock.
[0033] In the present invention, a port holder 7 is fixedly connected to the end of the combination lock cylinder 21 near the movable joint 4 within the lock housing 1. This port holder 7 defines a receiving slot 71 corresponding to the socket 11 for inserting the locking piece 41. It also defines a movable opening 72 for passing the male rod 25. The provision of the receiving slot 71 and movable opening 72 within the port holder 7 ensures that the locking piece 41 and the male rod 25 can be inserted and moved accurately, preventing unnecessary movement. This precise design helps improve the lock's operational accuracy, reduces operational failures due to alignment issues, and thus enhances the user experience.
[0034] Furthermore, the port seat 7 is connected to a key cover 8 at the end away from the male row 25, and the reset spring 6 is located between the key cover 8 and the male row 25. There are grooves for accommodating the reset spring 6 on both the key cover 8 and the male row 25 to ensure the stability of the reset spring 6.
[0035] The specific structure of the key cover 8 connected to the port seat 7 is as follows: a connecting port 73 is opened on the side wall of the port seat 7, a pin 74 is provided in the connecting port 73 to be inserted into the key cover 8, and a blocking seat 22 is connected to the end of the password lock cylinder 21 close to the movable joint 4, and the blocking seat 22 includes a blocking arm 221 that is supported on the key cover 8. The blocking arm 221 is provided with two and is respectively located on both sides of the lock plate 41. The key cover 8 can be connected to the port seat 7 through the arrangement of the pin 74 and the blocking arm 221. The key cover 8 can be opened when the password lock cylinder is unlocked. When pressed, the internal structure of the password lock cylinder 21 is pushed through the blocking seat 22 so that the password can be set. Since it is not the content to be protected by this application, and the structure for resetting the password has been widely set in existing password lock cylinders, basically all password locks have the function of setting their own passwords. It is common knowledge for those skilled in the art, so it will not be described in detail here. In addition, the blocking arm 221 provides additional safety protection, avoids the shaking of the lock plate 41, and prevents the lock plate 41 from being pulled out without authorization, greatly enhancing the safety performance of the lock.
[0036] In the present invention, a button seat 23 is fixedly connected to the combination lock cylinder 21 at one end near the fixed section 3, wherein the fixed section 3 is rotatably connected to the outer wall of the button seat 23, and the male rod 25 penetrates into the button seat 23, wherein the button 24 is movably fitted in the button seat 23.
[0037] The working principle of the folding combination lock described in this application is as follows:
[0038] Unlocking process:
[0039] 1. Enter the correct password: The user first needs to enter the correct unlocking password on the combination lock cylinder 21. The combination lock cylinder 21 consists of several rotatable combination rings, which are unlocked by rotating the corresponding number.
[0040] 2. Press button 24 to operate male rod 25: When the password is correct, press button 24 at one end of fixed section 3, which is fixedly connected to one end of male rod 25. After pressing button 24, male rod 25 begins to move along its axial direction and compresses return spring 6.
[0041] 3. The limiting lock block 251 leaves the locking notch 411: As the male shank 25 moves, the limiting lock block 251 fixed thereon also moves together until the limiting lock block 251 completely exits the locking notch 411 on the locking plate 41. At this point, the locking plate 41 is no longer constrained by the limiting lock block 251.
[0042] 4. Pull out the locking piece 41: Since the locking piece 41 can move freely, the user can easily pull out the locking piece 41 from the socket 11 on the side wall of the lock housing 1, so that the male row 25 passes through the male row passing groove 412 on the locking piece 41 to complete the unlocking action.
[0043] Locking process:
[0044] 1. When the combination lock cylinder 21 is unlocked, align the lock piece 41 on the movable joint 4 with the socket 11 on the side wall of the lock housing 1 and insert it. The lock piece 41 can push the male row 25 to compress the spring by inserting the inclined surface 413 and cooperating with the inclined surface 252 on the limiting lock block 251 until the male row 25 passes through the male row passage groove 412 and reaches the lock hole 411. The reset spring 6 resets and pushes the limiting lock block 251 into the lock hole 411 to lock.
[0045] 2. Locked state: After the limiting lock block 251 returns to the lock port 411, the lock port piece 41 can no longer be pulled out of the socket 11, unless the correct password is entered again and the male rod 25 is operated by the button 24 to make the limiting lock block 251 exit the lock port 411, and then it can be unlocked.
[0046] This design not only simplifies the complex structure of traditional folding locks, but also improves the convenience of use and overall safety.
[0047] It should also be pointed out that the terms indicated in the present invention, such as: "front", "rear", "vertical", "horizontal", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as limiting the scope of protection of the present invention.
[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
