[0031] The utility model is further described below in conjunction with the accompanying drawings.

[0032] like Figures 1 to 6 The photovoltaic solar electric push rod shown includes a motor 1, a reduction gear set 2, a push rod assembly 3, an upper shell 4, a lower shell 5, a sealing gasket 6, and a fixing assembly 7.

[0033] The sealing gasket 6 is made of EPDM rubber, which fully utilizes the properties of EPDM rubber such as good compression rate, high and low temperature resistance, UV resistance, and high protection level, so that the upper shell 4 and the lower shell 5 of the utility model have good sealing and waterproof performance.

[0034] The motor 1 drives the push rod assembly 3 to work through the reduction gear set 2 . The motor 1 and the push rod assembly 3 are both fixedly arranged on the lower shell 5 , and the reduction gear set 2 is arranged inside the lower shell 5 .

[0035] A first lip 51 is fixedly provided at the upper end of the lower shell 5 near its periphery around the circumference. A sealing groove 52 is opened at the upper end of the lower shell 5. The first lip 51 is located at the periphery of the sealing groove 52. The lower part of the sealing gasket 6 is located in the sealing groove 52.

[0036] A second lip 41 is fixedly provided at the lower end of the upper shell 4 near its periphery and around the circumference. The upper shell 4 is fixed to the lower shell 5 by screws, and the upper end of the first lip 51 abuts against the lower end of the second lip 41, and the upper end of the sealing gasket 6 abuts against the lower end of the second lip 41. When the upper shell 4 is fixed to the lower shell 5 by screws, the lower part of the sealing gasket 6 is located in the sealing groove 52, and the upper end of the sealing gasket 6 abuts against the lower end of the second lip 41, thereby achieving sealing and waterproofing between the upper shell 4 and the lower shell 5 through the sealing gasket 6.

[0037] A protective cover 53 is fixedly disposed inside the lower shell 5 , and the reduction gear set 2 is fixedly disposed inside the protective cover 53 , thereby providing better protection for the reduction gear set 2 .

[0038] The push rod assembly 3 includes an outer cylinder 31, a screw rod 32, a nut 33, a telescopic cylinder 34, a sliding ring 35, and an end cover 36. The reduction gear group 2 drives one end of the screw rod 32 to rotate, and the center of the sliding ring 35 is buckled on the other end of the screw rod 32. The telescopic cylinder 34 is sleeved on the screw rod 32, and the sliding ring 35 is slidably set on the inner wall of the telescopic cylinder 34. The outer cylinder 31 is sleeved on the telescopic cylinder 34, and the nut 33 is screwed on the screw rod 32, and the nut 33 is slidably set on the inner wall of the outer cylinder 31. The specific structure is: a slide rail is opened on the inner wall of the outer cylinder 31, and the nut 33 is slidably set on the slide rail.

[0039] When the telescopic cylinder 34 and the screw rod 32 move relative to each other, the sliding ring 35 slides back and forth on the inner wall of the telescopic cylinder 34. When the telescopic cylinder 34 and the screw rod 32 rotate relative to each other, the sliding ring 35 rotates on the inner wall of the telescopic cylinder 34. Therefore, the utility model can realize stable telescopic movement of the telescopic cylinder 34 through the cooperation between the sliding ring 35 and the nut 33.

[0040] The end cover 36 is fixedly arranged at one end of the outer cylinder 31 away from the reduction gear set 2 , a through hole is opened at the center of the end cover 36 , one end of the telescopic cylinder 34 passes through the through hole, and a sealing ring is fixedly arranged between the end cover 36 and the telescopic cylinder 34 .

The reduction gear set 2 is fixedly connected to the fixing sleeve 71. One end of the outer cylinder 31 is fixedly connected to the fixing sleeve 71. When the screw rod 32 rotates, relative rotation with the fixing sleeve 71 is achieved through the bearing 72.

[0042] The purpose of fixing and screwing the bearing sleeve 73 on the screw rod 32 is that the strength of the planar contact surface between the bearing sleeve 73 and the screw rod 32 is relatively small. After the bearing sleeve 73 is fixed and screwed on the screw rod 32, most of the pressure on the screw rod 32 is dispersed to the threaded contact surface between the bearing sleeve 73 and the screw rod 32, thereby solving the problem of insufficient strength of the thread contact surface between the bearing sleeve 73 and the screw rod 32.

[0043] A first assembly ring 81 is fixedly provided on the upper shell 4 , and a second assembly ring 82 is fixedly provided on one end of the telescopic cylinder 34 away from the reduction gear set 2 . Both the first assembly ring 81 and the second assembly ring 82 are used for assembly with other equipment.

[0044] The working principle of the utility model is as follows: the motor 1 drives the reduction gear set 2 to work, the reduction gear set 2 drives the screw rod 32 to rotate, and then drives the nut 33 to slide along the inner wall of the outer cylinder 31, the nut 33 drives the telescopic cylinder 34 to reciprocate and extend, and the telescopic cylinder 34 drives other equipment to operate.

[0045] The above description does not limit the technical scope of the present invention.
