Description

Technical Field

[0001] The utility model belongs to the technical field of door handle bases, and in particular relates to a door handle base with a self-locking function. Background Art

[0002] In existing door lock technology, a door handle base typically consists of a front base and a rear base, with a mechanical transmission mechanism used to achieve locking. These traditional door lock designs often rely on complex mechanical structures, such as gears and shift forks, to achieve locking and unlocking operations.

[0003] However, these traditional designs have some obvious defects, especially in terms of ease of operation, safety, maintainability and appearance design. The defects of the existing technology mainly include:

[0004] Many traditional door locks require multiple steps to lock or unlock, increasing complexity and time-consuming operations. Due to their complex mechanical structure, traditional door locks can present more points of failure and potential safety hazards, such as the risk of unauthorized opening. Complex internal structures make maintenance and component replacement difficult and time-consuming, increasing maintenance costs. Traditional door lock designs are often limited by their internal mechanical structure, making them difficult to achieve modern designs and poorly compatible with various door styles. Many traditional door locks lack intuitive status displays, making it difficult for users to easily determine whether the door is locked from outside.

[0005] In view of this, we propose a door handle base with a built-in locking function to solve the above problems. It can lock and unlock through a mechanical limit and locking mechanism, greatly improving the convenience of operation. The compact structure and modular components make maintenance and replacement of parts simpler and faster. Utility Model Content

[0006] The present invention aims to solve the technical problems that many traditional door lock designs in the above-mentioned prior art require users to perform multiple steps to lock or unlock, which not only increases the time cost of user operation, but also increases the complexity of operation, the complexity of internal structure, maintenance difficulties and poor status display.

[0007] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] A door handle base with a self-locking function comprises a front base and a rear base, a transmission square support is provided between the front base and the rear base, and a square support transmission plate is rotatably connected in a slot of the transmission square support;

[0009] The center of the rear base is plugged with a rear support limit sleeve fixed on the outer side of the transmission square support.

The rear support limit sleeve is provided with a transmission pin A inserted into the slot and located above the square support transmission plate, and the top end of the transmission pin A is snapped into the lock switch B. The lock switch B is snapped and positioned above the rear support limit sleeve, and the lock switch B is used in conjunction with the lock switch A.

[0010] A front support limit sleeve is inserted into the center of the front base, which is fixed on the outer side of the transmission square support. The outer side of the front support limit sleeve is sequentially sleeved with the front base cover, spring C and front handle limit plate from front to back. The front support limit sleeve is provided with a transmission pin B inserted into the slot and located above the square support transmission plate, and the top of the transmission pin B abuts against the switch display transmission part. The switch display transmission part is snap-fitted and positioned above the front support limit sleeve, and a spring B is provided in the U-shaped slot on the switch display transmission part. A switch display is inserted into one side of the switch display transmission part.

[0011] The front and rear bases are connected by a drive bracket, which has a slot inside. A drive plate sits within the slot and rotates within the bracket. When the user operates the door handle, the plate rotates, driving the entire transmission mechanism.

[0012] Limit Control: The rear and front limit sleeves are fixed to the outer sides of the transmission support. These sleeves control the movement of the transmission support through internal springs and limit plates. When lock switches A and B are activated, drive pins A and B, respectively, act on the transmission plate, restricting or allowing rotation.

[0013] Locking mechanism: The top of drive pin A engages lock switch B. When lock switches A and B are operated simultaneously (for example, by pressing or pulling them simultaneously), the square support drive plate is locked, preventing the drive support from rotating, thus achieving the locking function. Conversely, when lock switches A and B are released, the square support drive plate can rotate freely, achieving the unlocking function.

[0014] Status display: The switch display transmission member can change the position of the switch display according to the rotation state of the square support transmission piece through the action of spring B, thereby displaying the open and closed state of the door lock.

[0015] Users can easily lock and unlock the door simply by operating lock switches A and B, eliminating the need for complex operations. Mechanical limit and locking mechanisms ensure door lock security and prevent unauthorized opening.

[0017] The fixing of the rear base and the rear decorative cover can hide and encapsulate the transmission square branch, making it less susceptible to external influences such as dust, moisture, etc. At the same time, the rear decorative cover can play a beautifying role, making the appearance of the door handle base more neat and coordinated.

[0018] Preferably, the rear handle limit piece is fixed to the rear base by screws, and the rear base surface cover, spring A and the rear handle limit piece are enclosed in an installation cavity surrounded by the rear decorative cover and the rear base.

[0019] The rear handle stop, rear base cover, and spring A are enclosed within the mounting chamber, protecting them from damage and reducing maintenance costs. The screw fastening system provides a stable connection, ensuring long-term reliability.

[0020] Preferably, a lock switch limit plate is provided on one side of the lock switch B, and a positioning bead is horizontally inserted on the lock switch B and contacts the lock switch limit plate.

[0021] The design of the lock switch limit piece and positioning bead of the lock switch B can accurately control the position of the lock switch B, ensure its correct operation and positioning, and improve the reliability and durability of the door lock.

[0022] Preferably, the lock switch A passes through the rear decorative cover and the rear handle limit plate and is inserted into the square groove on the rear side of the lock switch B. The square groove on the lock switch B passes through the through hole A at the upper end of the rear handle limit plate.

[0023] Lock switch A mates with the square slot of lock switch B. This design allows for precise engagement between lock switches A and B, ensuring smooth locking and unlocking operations. The square slot and through-hole A design help simplify installation while maintaining a compact structure.

[0024] Preferably, the front handle limiting piece is screwed to the front base, and the front base surface cover, spring C and the front handle limiting piece are enclosed in an installation cavity surrounded by the front base and the front decorative cover.

[0025] The packaging of the front handle limiter, front base cover, and spring C is similar to the aforementioned rear component packaging. This design can also protect internal components and improve the stability and durability of the overall structure.

[0026] Preferably, the switch display transmission member passes through the through hole B on the front handle limit plate and the front base cover and is then plugged and positioned with the switch display.

[0027] The switch display transmission member cooperates with the front handle limit plate and the front base cover. This design enables the switch display transmission member to be accurately positioned with the switch display, ensuring the accuracy and reliability of the status display.

[0028] Preferably, the switch display transmission member passes through the switch display and is fixed with a switch display color plate, which includes a red plate and a green plate arranged vertically.

[0029] By arranging the red and green plates up and down, the open and closed status of the door lock can be intuitively displayed, providing users with clear visual feedback and increasing safety in use.
