[0006] A reducer housing with a dustproof sealing structure comprises an outer shell, a cover body is installed on the top of the outer shell, a connecting assembly is arranged between the bottom of the cover body and the top of the outer shell, and limiting assemblies are arranged on both sides of the cover body, a reducer body is installed in the inner cavity of the outer shell, the left end of the reducer body is connected to the input shaft, and the right end of the reducer body is connected to the output shaft, the input shaft and the output shaft both extend out of the outer shell, and dustproof sealing assemblies are arranged on the outer sides of the input shaft and the output shaft, and the dustproof sealing assembly comprises two fixing rings, the two fixing rings are respectively sleeved on the outer sides of the input shaft and the output shaft, and baffle covers are installed on the outer sides of the two fixing rings, and baffle cylinders are arranged inside the two baffle covers and outside the input shaft and the output shaft, and the two baffle cylinders are installed on the outer side of the outer shell, the outer side of the baffle cylinder is connected to a first sealing ring, and the inner side of the baffle cover is connected to a plurality of second sealing rings.
[0007] By adopting the above technical solution, during use, dust needs to pass through the two second sealing rings and the first sealing ring in a folded line path to enter the interior of the retaining cylinder, which increases the difficulty of dust entering the retaining cylinder, and further increases the difficulty of dust entering the interior of the outer shell. It can effectively prevent a large amount of dust from entering the interior of the outer shell, thereby improving the dustproof effect of the reducer housing.
[0008] Optionally, bolts are screwed between the two blocking covers and the fixing ring.

[0017] By adopting the above technical solution, when it is necessary to release the fixing effect of the limit rod on the connecting block, the L-shaped pull rod is pulled outward, and the L-shaped pull rod drives the mounting plate to move outward and stretches the reset spring. The mounting plate moves and drives the limit rod to move outward at the same time until the limit rod is separated from the limit groove.

The connection assembly 8 includes two groups of connection blocks 802, which are respectively fixedly mounted at the two ends of the top of the housing 1. Both ends of the bottom of the cover body 6 are provided with connection grooves 801 for plugging and matching with the connection blocks 802. The connection blocks 802 are plugged into the connection grooves 801, so that the cover body 6 and the housing 1 are more closely connected.
[0031] Please refer to the attached figure in the instruction manual Figure 1 and Figure 3 , limit assemblies 9 are provided on both sides of the cover body 6, and the limit assemblies 9 include two sets of fixing plates 901, and the two sets of fixing plates 901 are respectively fixedly installed at the two ends of the top of the cover body 6, and the inner cavities of the two sets of fixing plates 901 are slidably penetrated with L-shaped pull rods 903, and the two sets of L-shaped pull rods 903 are installed with mounting plates 904 on the side away from the center of the cover body 6, and the outer walls of the two sets of L-shaped pull rods 903 are sleeved with reset springs 902, and the reset springs 902 are located between the fixing plates 901 and the mounting plates 904. The two sets of mounting plates 904 are connected to the limiting rods 906 on the side close to the center of the cover body 6, and the outer sides of the connecting blocks 802 are provided with limiting grooves 905 that are plugged and matched with the limiting rods 906. When it is necessary to release the fixing effect of the limit rod 906 on the connecting block 802, pull the L-shaped pull rod 903 outward, the L-shaped pull rod 903 drives the mounting plate 904 to move outward and stretch the return spring 902. The mounting plate 904 moves and drives the limit rod 906 to move outward at the same time until the limit rod 906 is separated from the limit groove 905.
[0032] Please refer to the attached figure in the instruction manual Figure 1 and Figure 3 , both sides of the cover body 6 are provided with reserved holes 10 that match the limiting rod 906. Thus, the limiting rod 906 can smoothly pass through the reserved holes 10 and be inserted into the limiting groove 905.
[0033] Please refer to the attached figure in the instruction manual Figure 1 and Figure 2The inner cavity of the housing 1 is provided with a reducer body 5, the left end of the reducer body 5 is connected with an input shaft 2, the right end of the reducer body 5 is connected with an output shaft 3, both the input shaft 2 and the output shaft 3 extend out of the housing 1, and dustproof seal components 4 are provided on the outside of the input shaft 2 and the output shaft 3, and the dustproof seal components 4 include two fixing rings 401, the two fixing rings 401 are respectively sleeved on the outside of the input shaft 2 and the output shaft 3, and the outside of the two fixing rings 401 are provided with blocking covers 406, and the two blocking covers 406 are screwed with bolts 402 between the fixing rings 401. It is convenient to disassemble the blocking covers 406 and clean the inside regularly.
[0034] Please refer to the attached figure in the instruction manual Figure 1 , a retaining cylinder 403 is arranged inside the two retaining covers 406 and outside the input shaft 2 and the output shaft 3, and the two retaining cylinders 403 are installed on the outer side of the housing 1, and the outer side of the retaining cylinder 403 is connected with a first sealing ring 404, and the inner side of the retaining cover 406 is connected with a plurality of second sealing rings 405, and the number of the second sealing rings 405 is set to two, and the two second sealing rings 405 are symmetrically distributed about the center of the first sealing ring 404. Dust needs to pass through a folded line path to enter the interior of the retaining cylinder 403, thereby increasing the difficulty of dust entering the interior of the housing 1.
[0035] Working principle: During use, the blocking cover 406 is installed on the fixing ring 401 by means of bolts 402. Dust needs to pass through the two second sealing rings 405 and the first sealing ring 404 in a folded line path to enter the blocking cylinder 403, which increases the difficulty for dust to enter the blocking cylinder 403, and further increases the difficulty for dust to enter the interior of the outer shell 1. It can effectively prevent a large amount of dust from entering the interior of the outer shell 1, and through the setting of the sealing gasket 7, the sealing performance when the outer shell 1 and the cover body 6 are connected is increased, thereby further improving the dustproof effect.
[0036] When the reducer body 5 inside the housing 1 fails, the staff holds the two L-shaped pull rods 903 and pushes the two L-shaped pull rods 903 to move outward and away from each other. When the L-shaped pull rods 903 move, they drive the mounting plate 904 to move outward and stretch the reset spring 902. When the L-shaped pull rods 903 move, they drive the limit rod 906 to move until the limit rod 906 is separated from the limit groove 905, thereby releasing the fixing effect of the limit rod 906 on the connecting block 802. At this time, the L-shaped pull rod 903 is pulled upward, and the L-shaped pull rod 903 drives the cover body 6 to move upward. The cover body 6 moves upward to separate the connecting groove 801 from the connecting block 802, and the cover body 6 can be removed from the top of the housing 1. The staff then checks and repairs the reducer body 5.
[0037] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
