Sliding door, cab including sliding door and engineering machine

Abstract

The invention discloses a sliding door, a cab including the sliding door and an engineering machine. The sliding door comprises a door frame, a door plate and a sealing assembly arranged between the door frame and the door plate, wherein the sealing assembly comprises a brush and a rubber strip, the brush is close to an external space of the sliding door, and the rubber strip is close to an internal space of the sliding door. On one hand, the door frame can be in flexible contact with the door plate through the brush arranged between the door frame and the door plate, sliding of the sliding door is not affected, and sliding smoothness of the sliding door can be ensured; on the other hand, the brush and the rubber strip form a dual-sealing structure, the brush close to the external space of the sliding door plays wind-proof, dustproof and snow-proof effects and the rubber strip close to the internal space of the sliding door further plays a waterproof effect to tightly seal guiding rails between the door frame and the door plate, upper and lower guiding rail sealing during vehicle door closing is achieved, and the good wind-proof, dustproof, snow-proof and waterproof effects are played. In addition, the whole structure is safe, reliable, low in cost and convenient to maintain and replace.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a sliding door, a cab including the sliding door, and engineering machinery. Background technique [0002] Compared with the rotary hinged door, the sliding door can greatly reduce the size of the door opening space, improve the stress state of the body, and provide the occupants with a more comfortable way of entering and exiting the cab, and is increasingly used in construction machinery cabs. widely. [0003] At present, the sliding doors of construction machinery cabs at home and abroad generally adopt straight-rail sliding doors. Since the straight-rail sliding doors do not need to change the track, the corresponding sealing method cannot use the sealing strip rubber bubble of the track-changing sliding door. Compression sealing method. Therefore, how to provide a sealing structure with good windproof, dustproof, snowproof and waterproof effects for the guide rail of t...
