Description

Technical Field

[0001] This utility model relates to the field of latch technology, and in particular to a steel rotary latch. Background Technology

[0002] With the ever-increasing security requirements of modern access control systems and equipment, traditional lock and latch designs are gradually failing to meet increasingly stringent security demands. Many existing rotary latch devices, while capable of basic locking and unlocking functions, suffer from problems such as accidental operation, operational complexity, and unstable locking. These issues not only reduce equipment security but also negatively impact user experience and lifespan.

[0003] Traditional rotary latch designs mostly employ mechanical rotary structures. While these structures can perform the functions of rotary locking or unlocking, they often have the following shortcomings in practical applications:

[0004] 1. High risk of misoperation: In traditional designs, rotating structures often do not effectively limit the direction of rotation. Users are prone to incomplete unlocking or failure to lock due to incorrect operation direction or force, which in turn affects the security of the device.

[0005] 2. Inconvenient operation: Most existing rotary latches require users to apply a lot of force, or the operation steps are cumbersome, lacking intuitiveness and ease of use, which may increase the difficulty of operation for users, especially in emergency situations.

[0006] 3. Poor locking stability: Many traditional lock designs fail to adequately consider the cooperation between the bolt and the rotating structure during locking, which can easily lead to bolt jamming or incomplete locking, resulting in compromised equipment security.

[0007] 4. Susceptible to external interference: Existing rotating handles often lack sufficient protection and may protrude outwards when not in use, making them susceptible to external impacts or pressure, which can affect the lock's lifespan or operational performance.

[0008] Therefore, it is essential to invent a steel rotary latch. Utility Model Content

[0009] To address the aforementioned technical problems, this utility model provides a steel rotary latch, which solves the issues of high risk of misoperation, inconvenient operation, poor locking stability, and susceptibility to external interference inherent in existing latch structures. A steel rotary latch includes a lock box, a mounting plate, a rotating structure, a connecting handle, a rotating handle, and a positioning structure. The mounting plate is fixedly mounted on the outer side of the lock box and is also fixedly mounted on a door panel. The rotating structure is mounted on one side inside the lock box. The connecting handle is rotatably mounted on the outer side of the rotating structure and is fixedly mounted on the top of the connecting handle. The positioning structure is fixedly mounted on the other side inside the lock box.

[0010] The rotating structure includes a rotating base, a rotating shaft, a support platform, and a locking tongue. The rotating base is installed on one side inside the lock box, and the rotating shaft is rotatably installed inside the rotating base. The support platform is fixedly installed at one end of the rotating shaft, and a connecting handle is rotatably installed on its outer side. The locking tongue is fixedly installed at the other end of the rotating shaft.

[0011] The positioning structure includes an outer limiting frame, an inner limiting frame, an adsorption point, and an opening / closing lock. The outer limiting frame and the inner limiting frame are both fixedly installed on one side inside the lock box. The adsorption point is fixedly installed inside the gap between the outer limiting frame and the inner limiting frame, and the opening / closing lock is fixedly installed on one side inside the lock box, located at the center of the outer limiting frame and the inner limiting frame.

[0012] The rotating shaft inside the rotating structure can rotate inside the rotating seat, and the rotation of the rotating shaft can drive the locking tongue to rotate. The locking tongue is made of an "L"-shaped steel metal plate, and the locking tongue has two locking tongues, which are 90 degrees apart. In the locked state, the first locking tongue extends outward to lock. When the locking tongue rotates to the right, the first locking tongue disengages, and the second locking tongue rotates upward to lock. When the locking tongue rotates to the left, the first locking tongue disengages, and the second locking tongue does not enter the locked state. At this time, the latch is open, which has the following functions: ① Realizing the locking and unlocking functions: The rotating structure drives the locking and unlocking functions through the rotating shaft. 1. **The rotating bolt rotates to complete the locking and unlocking operation of the rotary latch, ensuring the safety of the door or equipment:** 2. **Supporting and transmitting rotational force:** The rotating base and rotating shaft in the rotating structure work together to support and transmit rotational force, enabling the rotating handle to effectively drive the connecting handle to rotate, thereby controlling the operation of the entire locking system; 3. **Ensuring stable bolt movement:** The support platform in the rotating structure fixes the rotating shaft, ensuring that the bolt can move smoothly and accurately during locking or unlocking, thus achieving a reliable locking effect; 4. **Preventing accidental opening:** The rotating structure is designed to rotate only in a specific direction, ensuring that the rotating handle must be turned in the correct direction when unlocking. This design effectively prevents accidental operation, avoids improper unlocking of the bolt, and ensures door security.

[0013] The rotating handle is made of a steel metal ring and can be turned manually. The rotating structure is rotated through the connecting handle. The rotating handle can be bent downward and embedded inside the positioning structure. It has the following functions: ① Controlling the rotation of the rotating structure: The rotating handle is connected to the rotating structure through the connecting handle, so that the rotating structure can rotate, thereby realizing the locking or unlocking operation; ② Providing convenient operation: The rotating handle is usually made of a steel metal ring and can be turned manually, providing a convenient manual operation method, so that users can easily operate the rotating structure when needed.

[0014] The overall shape of the positioning structure matches the rotating handle, and the positioning structure can stably place the rotating handle inside it through the adsorption points; the adsorption points are composed of several magnetic blocks; the lock is opened and closed by a key, which can make the rotating structure rotate or lock, and has the following functions: ① Stabilize the position of the rotating handle: The positioning structure, through the design of the adsorption points and the outer and inner limiting frames, can stabilize the position of the rotating handle, ensuring that the rotating handle will not shift during operation and avoiding misoperation; ② Increase operational safety: The lock is controlled by a key, which can effectively open and close the rotating structure, preventing unauthorized personnel from misoperating or illegally opening it, thus improving the security of the lock; ③ Accommodate the rotating handle: The positioning structure can accommodate the rotating handle, preventing the rotating handle from protruding outward when not in use, and avoiding damage or interference to the rotating handle caused by external impact or improper operation.
