Abstract
Description
Technical Field
[0001] This utility model relates to a lock handle, specifically a lock handle device with short stroke and forward / backward movement indication. Background Technology
[0002] Currently, some locks feature pop-out handles; these are also known as handle-mounted flat locks. Handle-mounted flat locks are a type of door lock with a handle, commonly found on electrical cabinets. These cabinets are typically made of steel and are used to protect components, requiring this type of lock to prevent the cabinet door from being opened arbitrarily. These handle-mounted flat locks generally include a base, handle, pivot, and bolt assembly. The base contains a handle that opens or closes via a lock cylinder. For ease of operation, these handles, in addition to the lock cylinder, also include a button, latch, or hook for temporarily opening the handle. Other similar products utilize a combination of a handle-controlled sliding plate, a start dial, and an unlocking motor to achieve the temporary opening or closing function of the handle, such as the utility model disclosed in Chinese patent document CN213510050U, authorized on June 22, 2021, entitled "A Cabinet Lock Structure." The structural designs of these products and similar products are overly complex, leading to inconvenient production and assembly, high production costs, and a lack of clear locking / unlocking indicators. Summary of the Invention
[0003] To overcome the aforementioned shortcomings, the purpose of this utility model is to provide a lock handle device with short stroke and forward / backward movement indication, thereby solving the technical problems of existing similar products having overly complex structural designs, resulting in inconvenient production and assembly, high production costs, and a lack of unlocking or locking indicators. This objective is achieved through the following technical solution.
[0004] A lock handle device with short stroke and forward / backward movement indication is disclosed. The main body of the lock handle device is a handle. One end of the handle is hinged and fixed to a rotating shaft on one side of the handle groove inside the base. When the lock cylinder assembly in the lock cylinder hole at the other end of the handle is rotated, it drives the bottom bolt to move. At the same time, the handle locks itself or pops out of the handle groove inside the base. The key structural design point is that while the lock cylinder assembly is fixed to the handle by the lock cylinder mounting block at the bottom of the handle, the bolt at the bottom of the lock cylinder assembly moves through the lock cylinder mounting block and inserts into one side of the handle groove fixed to the base in the locked state. A moving block is provided in the lock cylinder mounting block on one side of the lock cylinder assembly above the bolt. One end of the moving block abuts against the lock cylinder mounting block by a spring, and the other end of the moving block inserts into or abuts against the hole or outer diameter of the lock cylinder assembly through the lock cylinder mounting block. The aforementioned moving block is located on either side of the lock cylinder hole in the handle, with the hinged side being the best. Compared to the existing lock cylinder assembly with corresponding hook blocks and other components in the press-fit shell at the bottom, this structure is more convenient to manufacture and assemble, has better stability, and occupies less space. The spring of the moving block is provided with a corresponding spring post or spring groove.
[0005] A red-green viewing window is provided on one side of the lock cylinder hole on the handle above the moving block. When the moving block is inserted into or abuts against the slot or outer diameter of the lock cylinder assembly through the lock cylinder mounting block, the red or green indicator areas on both sides of the top of the moving block are aligned with the red-green viewing window on the handle. Thus, the moving block's position and status can be clearly seen through the red-green viewing window on the handle.
[0006] The indicator area at one end of the moving block is located on the raised side edge above the spring. The other symmetrical end of the moving block has a raised round head post. The moving block is inserted into a slot on one side of the outer diameter of the lock cylinder assembly through the round head post, or abuts against the outer diameter of the other side of the lock cylinder assembly. Thus, the moving block's insertion into or abutting against the slot or outer diameter of the lock cylinder assembly through the round head post results in better stability and positioning. The end of the moving block can also adopt a bolt or rectangular protrusion shape.
[0007] The lock cylinder mounting block contains a downward-protruding cylindrical chamber for the lock cylinder assembly. The moving block and spring are housed in a groove on one side of the top cavity opening of the lock cylinder mounting block. The outer diameter skirt of the top cavity opening of the lock cylinder mounting block is integrated with the bottom of the handle, forming a single plane. This reduces the space occupied by the components and makes the bottom of the handle flatter.
[0008] This utility model has a reasonable and simple structural design, is convenient to produce, assemble and apply, and has simple and clear unlocking or locking indicators; it is suitable for use as a lock handle device with short stroke and forward and backward movement indicators, as well as for structural improvements of similar products.

[0016] The structure and use of this utility model will now be further described with reference to the accompanying drawings. Figures 1-6 As shown, the main body of the lock handle device is a handle 1. One end of the handle is hinged and fixed to a rotating shaft on one side of the handle groove inside the base. When the lock cylinder assembly 2 in the lock cylinder hole 101 at the other end of the handle rotates, it drives the bottom latch 3 to move. At the same time, the handle locks itself or pops out of the handle groove inside the base. Its specific structure is as follows: The lock cylinder assembly is fixed to the handle by the lock cylinder mounting block 4 at the bottom of the handle. The latch at the bottom of the lock cylinder assembly moves through the lock cylinder mounting block and inserts into one side of the handle groove fixed to the base while in the locked state. A moving block 5 is provided in the lock cylinder mounting block on one side of the lock cylinder assembly above the latch. One end of the moving block abuts against the lock cylinder mounting block through a spring 6. The other end of the moving block inserts into or abuts against the hole or outer diameter of the lock cylinder assembly through the lock cylinder mounting block. Meanwhile, a red-green viewing window 102 is provided on one side of the lock cylinder hole 101 on the handle above the moving block. When the moving block is inserted into or abuts against the slot or outer diameter of the lock cylinder assembly through the lock cylinder mounting block, the red indicator area 501 or green indicator area 502 on both sides of the top of the moving block is aligned with the red-green viewing window 102 on the handle.
[0017] The indicator area at one end of the aforementioned moving block is located on the raised side edge above the spring. The other symmetrical end of the moving block has a raised round head post 503. The moving block is inserted into a slot on one side of the outer diameter of the lock cylinder assembly through the round head post, or abuts against the outer diameter of the lock cylinder assembly on the other side. The chamber of the lock cylinder assembly is housed within the lock cylinder mounting block, protruding downwards in a cylindrical shape. The moving block and spring are positioned in a groove on one side of the top cavity opening of the lock cylinder mounting block. The outer diameter skirt of the top cavity opening of the lock cylinder mounting block is integrally connected to the bottom of the handle, forming the same plane.
[0018] In use, one end of the handle of the lock handle device is hinged and fixed to a rotating shaft on one side of the handle slot inside the base. The rotating shaft, extending from the bottom of the base, is rotated and locked to the cabinet door on which the lock handle device is installed via a steel bolt and other components. That is, when the key is inserted and the lock cylinder assembly is turned, the lock cylinder assembly causes the bolt to disengage from the base, and at the same time, the lock cylinder assembly pushes against the moving block and retracts into the lock cylinder mounting block. The green indicator area on the top of the moving block aligns with the red-green viewing window of the handle, and the handle automatically pops out. After the handle is used, it retracts into the base. Turning the lock cylinder assembly with the key causes the lock cylinder assembly to lock the bolt to the base. The round head of the moving block inserts into the slot of the lock cylinder assembly, and the red indicator area on the top of the moving block aligns with the red-green viewing window of the handle.
[0019] This lock handle device features a simple design and small footprint. Existing similar products require a large space to accommodate the red and green dot structure. This lock handle device, through optimization of the lock cylinder structure, allows for short-stroke movement within the existing space. In particular, when applied to existing charging stations, this lock handle device allows the red and green dots on the lock to indicate the open and closed states of the cabinet, while also enabling the handle to automatically pop up.
