[0004] End seat door (22) is fixed on motor front end seat (21) by bolt (23), and end seat door (22) is rotatably clamped on inclined block (5) by handle (4).

[0005] The utility model has the advantages of the following structure:

[0006] 1The organic glass window assembly (7) is fixed on the door plate (2) of the end seat door (22) by means of countersunk screws (8) which are fixed not higher than the surface of the window frame (11), and the whole appearance is beautiful, easy to install, and convenient for replacement when the organic glass (10) is damaged.

[0007] 2The sealing gasket (9) in the organic glass window assembly (7) is processed from a whole rubber plate, without joints, which can better enhance the sealing of the end seat door (22); the inclined block (5) has an inclination on one side, which is clamped on the inclined block (5) by rotating the handle (4), effectively fixing the end seat door (22).

[0008] 3The size of the door frame window is 420mm (width) x 1070mm (height), which is convenient for maintenance personnel to explore the front end seat to maintain the commutator and replace the brush. The thickness of the organic glass in the organic glass window (10) reaches 4mm, and the observable part of the organic glass (10) accounts for about 40% of the door frame window area, which is high in strength and convenient for observing the state of the commutator and brush during motor operation.

[0009] 4The first channel steel (14), the second channel steel (15), the third channel steel (16), the fourth channel steel (17), the fifth channel steel (18), the first steel plate (12), and the second steel plate (13) are welded on the inner side of the door plate (2), which enhances the strength of the door plate, reduces vibration, and prevents deformation.
