[0029] Embodiment 1

[0030] With reference to the accompanying drawings, Figures 1-4 , an automatic gear reducer of the embodiment comprises a reducer body 100, the reducer body 100 comprises an output end 110, a body 120 and a tail end 130, the tail end 130 is provided with a mounting ring 131, a fan is arranged in the mounting ring 131, a power shaft in the body 120 is connected to the output end 110 at one end and extends through the body 120 to connect the fan in the tail end 130 at the other end, a protection assembly 150 is arranged at the ring opening of the mounting ring 131, an outer cover 140 is sleeved on the mounting ring 131, a ventilation opening 141 is arranged on the outer cover 140, and the outer cover 140 is detachably connected with the mounting ring 131.

[0031] The protection assembly 150 of the embodiment comprises an intermediate piece 151 and a movable rod 152, a plurality of threaded columns are arranged on the mounting ring 131, the two ends of the intermediate piece 151 are fixedly connected with the mounting ring 131, one end of the movable rod 152 is rotatably connected with the mounting ring 131 through a rotating shaft, and the other end of the movable rod 152 is provided with a through hole and locked on the threaded column through a screw.

[0032] The intermediate piece 151 of the embodiment comprises an intermediate ring 153 and a pull rod 154 symmetrically connected with the intermediate ring 153, the intermediate piece 151 is integrally formed, the intermediate piece 151 is fixedly connected with the mounting ring 131 through the pull rod 154, and a plurality of movable rods 152 are distributed around the intermediate ring 153.

[0033] A plurality of threaded holes 155 are arranged on the intermediate ring 153 of the embodiment, the threaded holes 155 one-to-one correspond to the movable rods 152, and the through hole of the movable rod 152 rotates around the rotating shaft along a track passing through the corresponding threaded hole 155.

[0034] The intermediate ring 153 of the embodiment is provided with a socket 156, the outer cover 140 is provided with a plug shaft 142, the outer cover 140 is sleeved on the mounting ring 131 and the plug shaft 142 is inserted into the socket 156, and the outer cover 140 is screw-connected with the mounting ring 131.

[0035] Working principle: because the reducer works for a long time, the end of the fan installed on the reducer will accumulate and attach impurities, affecting its heat dissipation performance, and long-term failure to clean up will cause the performance of the reducer to decline, so compared with the traditional reducer, the tail end 130 of the reducer of the design is provided with an outer cover 140, which can be cleaned by removing the outer cover 140 to clean the impurities attached to the outer cover 140. Because the outer cover 140 is removed, the entire fan is exposed, which is dangerous, so a protection assembly 150 is provided, wherein the middle piece 151 is integrated on the mounting ring 131 to ensure the integrity of the whole, and the movable rod 152 can be rotatably installed on the middle ring 153 or the threaded column, that is, before the outer cover 140 is installed, the movable rod 152 is detached from the connection of the middle ring 153, and the movable rod 152 is rotated to connect the threaded column at one end, which reduces the obstruction of the movable rod 152 to air flow, and also avoids the attachment of impurities on the movable rod 152, which is inconvenient for subsequent cleaning. Although there are few attachments on the top, when the outer cover 140 needs to be cleaned, the movable rod 152 needs to be connected to the middle ring 153 after the outer cover 140 is removed, which ensures the overall protection performance, and even if the outer cover 140 is being cleaned, the reducer can still be started to work.

[0036] The above-described embodiments only express certain embodiments of the present application, and the description is more specific and detailed, but it should not be understood as limiting the scope of the present application; It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which belong to the protection scope of the present application; Therefore, the protection scope of the present application patent should be subject to the appended claims.
