Description

Technical Field

[0001] This utility model belongs to the field of door lock technology, specifically relating to the lock body of a door handle lock. Background Technology

[0002] Door handle locks are a widely used door locking device in daily life, typically used in residences, offices, hotels, catering equipment, and various equipment cabinets to achieve the functions of opening, closing, and securing doors. Traditional door handle locks often have the following problems during use:

[0003] Most existing door handle locks use simple mechanical structures for their lock bodies. When users operate the door handle, it is easy for it to be over-rotated or deviate from the normal operating trajectory. This not only reduces the user experience but may also lead to accelerated wear of internal parts of the lock body, thereby affecting the lock's lifespan.

[0004] Many traditional door handle locks lack an effective positioning structure. With numerous parts and complex manufacturing processes, the lack of a proper positioning mechanism can lead to the door handle becoming loose or wobbly during operation. Over time, this loosening will worsen, causing a decline in lock performance and even compromising the security of unlocking.

[0005] Existing door handle locks typically lack clear tactile feedback, making it difficult for users to accurately determine the lock's position or operational status. This lack of feedback is particularly problematic in low-light conditions or when operating blindly, as it can easily lead to misoperation or security risks.

[0006] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Utility Model Content

[0007] In view of the technical problems mentioned in the background art, the purpose of this utility model is to provide a lock body for a door handle lock that uses positioning and matching connection to enable a single component of the door handle to have multiple functions, simplify the production process, make the structure more compact and reasonable, make the lock body move more accurately during use, and ensure that the door handle is more stable during movement, avoiding excessive rotation or deviation from the normal operating trajectory, and making the production and assembly of the door handle lock convenient, so as to solve the technical problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a door handle lock body, comprising a handle, a bolt, a base plate, a special-shaped fastening bolt, a spring washer, an arc-shaped opening and closing positioning block, a guide tube, a spring, a positioning ball, a flat washer, a lock nut, and a top cover. The handle is mounted on the bolt, and the bolt is mounted on the base plate. The handle has a special-shaped fastening bolt mounting positioning hole, a guide tube mounting hole, a guide tube mounting limit step, a lock nut, and a top cover cavity. The bolt has a cam portion that rises from low to high and a circular mounting body. The circular mounting body has a guide tube mounting hole, a positioning through hole, and a special-shaped bolt mounting and positioning through hole. The base plate has several mounting bolt through holes and a bolt mounting boss on its surface. One side surface of the bolt mounting boss has several positioning recesses and positioning plates. The positioning ball and the positioning recesses are positioned in cooperation.

[0009] The present invention has the following advantages: through multiple positioning and connection, the structure is simplified, making the connection of each component of the door handle more secure and reliable, the opening and closing action during actual use more accurate and free, and ensuring that the door handle is more stable during movement, avoiding damage caused by over-operation. The structure is simple and easy to assemble. Attached Figure Description
