Description

Technical Field

[0001] The utility model belongs to the technical field of lock body drive boxes, and particularly relates to a lock body spur gear drive box. Background Art

[0002] The lock body drive box is a key component in the lock body. It is responsible for converting the input rotational motion into the linear motion of the lock core, thereby realizing the opening and closing of the lock.

[0003] Traditional lock body drive boxes adopt simple mechanical drive methods, such as helical gears or worm gears. These drive methods have relatively low drive efficiency and large energy losses. More space may be required to accommodate more drive components because they may need larger gears to transmit the same force, resulting in an increase in the overall volume. Due to the complex design or more components of traditional helical gears or worm gears, the difficulty of maintaining and replacing parts is relatively large, increasing the usage cost. Content of the Utility Model

[0004] The present invention aims to solve the technical problems of the traditional lock body drive box in the prior art, which are poor in terms of efficiency, space, and durability.

[0005] To achieve the above object, the utility model provides the following technical solutions:

[0006] A lock body spur gear drive box includes a cover plate and a bottom plate. Inside the space enclosed by the cover plate and the bottom plate, a toothed plate, a toothed sliding gasket fixedly connected to the toothed plate, a compression spring, a gear square rod, and a toothed drive rod are installed;

[0007] The gear square rod is connected to the upper cylinder and the cover plate, and a gear A for transmitting power is provided on the gear square rod;

[0008] The toothed plate is located below the cover plate and meshes with the gear A of the gear square rod for transmitting power;

[0009] The toothed drive rod is connected to the gear square rod and the bottom plate, and a gear B for transmitting power integrally formed therewith is provided on the toothed drive rod; The integrally formed toothed drive rod and gear B are more compact in structure and have no assembly gaps, thereby improving the overall strength and stability. Integrally formed components usually perform better in terms of wear resistance and impact resistance.

[0010] The toothed sliding gasket is located on the bottom plate and meshes with the gear B of the toothed drive rod to play a role in transmitting power.

[0011] Through the meshing of the gear A of the gear square rod with the toothed plate and the meshing of the gear B of the toothed drive rod with the toothed sliding gasket, the transmission of input power to output power is realized.

[0012] Preferably, the cover plate and the bottom plate are fixed by stud bolts.

[0013] Preferably, a gasket for filling the gap between the gear square rod and the toothed plate is sleeved on the outer side of the toothed transmission rod, which plays a role in sealing and shock absorption.

[0014] Preferably, one end of the compression spring is connected to the connecting toothed plate and the toothed sliding gasket, and the other end is connected to the groove on the bottom plate. The compression spring provides a preloading force, which helps to reduce the impact and noise when the gears mesh.

[0015] Preferably, the convex plate on the toothed plate passes through the rectangular hole on the cover plate, ensuring the correct position of the toothed plate during the transmission process and preventing deviation.

[0016] Preferably, when the gear square rod or the toothed transmission rod rotates, through the meshing of gear A and the toothed plate or the meshing of gear B and the toothed sliding gasket, the toothed plate or the toothed sliding gasket follows the movement to realize the opening and closing function of the lock. This meshing method realizes the power transmission from the gear square rod to the toothed plate and then to the toothed sliding gasket, making the opening and closing actions of the lock smooth and reliable.

[0017] Compared with the prior art, the technical effects and advantages of the present utility model are:

[0018] In this positive gear transmission box of the lock body, gear A is located on the gear square rod, which is used to receive external force and transmit it to the toothed plate. The design of the toothed plate enhances the structural stability and durability. At the same time, through the meshing with gear B of the toothed transmission rod, the power is transmitted to the toothed transmission rod. The integral molding design of the toothed transmission rod and gear B simplifies the structure, reduces the number of parts, improves the strength and stability. The toothed sliding gasket meshes with gear B of the toothed transmission rod to play a role in power transmission;

[0019] The opening and closing of the lock are realized through the meshing of gear A and the toothed plate, or the meshing of gear B and the toothed sliding gasket. This design makes the opening and closing actions of the lock smooth and reliable, simplifies the transmission mechanism, improves the compactness and reliability, and is convenient for automatic control and the improvement of work efficiency. The design of this positive gear transmission box of the lock body realizes the efficient transmission of power and the precise control of the lock through precise gear meshing and optimized structural design. At the same time, it also improves the overall durability, stability and operation convenience. Brief Description of the Drawings
