[0021] Please refer to Figure 1-4 A reduction gearbox for a joint mechanism of a robot comprises a reduction gearbox body 1, a mounting hole 2 is provided on the reduction gearbox body 1, dustproof plates 3 are fixedly connected to the left and right sides of the reduction gearbox body 1, a protective strip 4 is fixedly connected to the outer side of the reduction gearbox body 1, observation windows 5 are provided at the middle positions of the front and rear sides of the reduction gearbox body 1, a threading groove 6 is provided at the lower end of the back side of the reduction gearbox body 1, and a limiting sleeve 7 is fixedly connected to the threading groove 6.

[0022] The mounting holes 2 are opened at four right angles of the reduction gearbox body 1, and three groups of mounting holes 2 that are not in the same plane are opened at the four right angles. Having multiple groups of mounting holes 2 that are not in the same plane provides more installation options and flexibility. Different combinations of mounting holes 2 can be selected according to actual needs and space limitations to better adapt to the design and environment of the robot. Since the structure of the robot may be affected by space limitations and other factors, having multiple groups of mounting holes 2 in different planes can help optimize the structural layout of the robot, making the overall design more compact and effective.

[0023] The left and right sides of the reduction gearbox body 1 are provided with heat dissipation grooves, and dustproof plates 3 are fixedly connected to the heat dissipation grooves, and a dustproof net is connected to the dustproof plate 3. The presence of the heat dissipation grooves helps to improve the heat dissipation effect of the reduction gearbox body 1. By arranging heat dissipation grooves on the left and right sides, the heat dissipation surface area can be increased, and the heat dissipation efficiency can be effectively improved to ensure that the reduction gearbox body 1 can maintain an appropriate temperature during operation. The addition of the dustproof plate 3 can effectively prevent dust, particulate matter and other impurities from entering the heat dissipation groove and the reduction gearbox body 1, which helps to maintain the cleanliness of the interior of the reduction gearbox body 1, reduce friction and wear, and extend the service life of the reduction gearbox body 1. The dustproof net is connected to the dustproof plate 3, which can filter tiny particles in the air more finely to prevent particles from entering the reduction gearbox body 1.

[0024] The outer side of the protective strip 4 is arranged in an arc-shaped structure. The protective strip 4 is made of rubber material. The rubber material has good elasticity and buffering properties, which can effectively absorb collision or impact force and reduce the damage or vibration caused by the robot colliding with external objects during operation. The arc-shaped protective strip 4 can better surround the outer contour of the robot and ensure a wider contact area with the surrounding environment, thereby reducing the possibility of accidental contact or damage to surrounding equipment, walls and other objects. The rubber protective strip 4 reduces the impact force during collision due to its soft characteristics, thereby reducing the risk of damage to the reduction box body 1.

[0025] The observation window 5 is made of a tempered glass plate. Compared with ordinary glass, tempered glass is stronger and has higher impact resistance, which means that even if it is hit or impacted with greater force, tempered glass is not easy to break or shatter, thereby providing higher safety. When tempered glass is broken by extreme force, it will break in small pieces instead of sharp fragments. These small pieces are usually blunt, reducing the risk of injury to the human body, so it has more advantages in terms of safety. Tempered glass has better heat resistance than ordinary glass. It can withstand higher temperature changes without breaking easily, so it is more reliable in environments that need to face temperature changes frequently. While maintaining its strength and safety, tempered glass still maintains good transparency, which means that the observation window can provide a clear view, allowing users to clearly observe the internal operation without worrying about the glass obstructing their view.

[0026] The limiting sleeve 7 is made of rubber material, and one end of the limiting sleeve 7 is set in a V-shaped structure. When the line of the reduction box body 1 passes through the threading groove 6, it can be limited by the limiting sleeve 7 to prevent the line from falling off during use.

[0027] The upper and lower surfaces of the reduction gearbox body 1 are fixedly connected with an acrylic label plate 8, and one end of the acrylic label plate 8 is set to an open structure. The open structure allows one end of the acrylic label plate 8 to be easily opened, which is convenient for users to replace the label content or perform maintenance. There is no need to remove the entire acrylic label plate 8. Only the opening part needs to be opened to conveniently replace the label, saving time and energy. The opening structure allows users to quickly view the internal information under the acrylic label plate 8, such as model, serial number, technical parameters, etc., without completely removing the acrylic label plate 8, which can improve operating efficiency, especially when information needs to be frequently checked or updated.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
