The common medium-sized tractor is provided with a safety protection frame or a safety cab which can be optionally installed, and the cab of the large-sized tractor is generally standard equipment. The driver's cab tends to be of a fully enclosed construction, most often with large glass windows to ensure a good field of view. The cab of the medium-sized tractor is generally provided with a heating device without air conditioning equipment, and the front window and the rear window of the cab can be opened to facilitate ventilation. The cab of a large tractor typically has heating and air conditioning equipment.
A sealing structure for operating a pull rod in a tractor cab has certain defects, and the sealing structure at the pull rod in the existing tractor cab with a certain model is shown in figure 1, wherein a pull rod assembly 1, a pull rod rubber ring 2, a floor 3 and a check ring 4 are included. The structure has the following defects: firstly, the sealing performance of a tractor cab is poor, dust is easy to enter the operation position, the comfort of a driver is affected, and the refrigerating effect of an air conditioner is poor; secondly, due to the fact that a gap exists between the check ring and the floor, the pull rod rubber ring and the floor are abraded due to repeated friction, the pull rod rubber ring can fall off, and therefore the sealing performance of the cab is poor.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem that the sealing performance of a pull rod in the existing tractor cab is poor, an improved sealing structure at the pull rod of the tractor cab is provided. The utility model discloses can solve the not good, unreliable problem of seal structure of pull rod department seal structure in the current tractor driver's cabin.
In order to achieve the purpose, the invention is realized by the following technical scheme:
the improved sealing structure at the pull rod of the tractor cab comprises a pull rod assembly and a floor, wherein the pull rod assembly penetrates through the floor.
Further, the pull rod assembly further comprises a pressing plate arranged above the rubber pad, and the pull rod assembly penetrates through the pressing plate.
And furthermore, bolts are matched with nuts to fix the pressing plate and the rubber pad on the floor at two sides of the pull rod assembly.
Further, a gap is arranged between the pressure plate and the pull rod assembly.
The beneficial technical effects are as follows:
the utility model discloses an improvement seal structure of tractor driver's cabin pull rod department improves the pull rod rubber ring among the prior art and is fixed in the floor for the rubber pad on, simultaneously with the clearance fit design of pull rod rubber ring among the prior art with the retaining ring do the utility model discloses the rubber pad that has the draw rod hole closes the interference fit of piece with the pull rod. The problem of among the prior art pull rod department seal structure sealed effect not good, seal structure is unreliable is solved.
The rubber pad with the pull rod hole is pressed by the pressing plate, the pressing plate and the rubber pad are fixed on the floor by the bolt matched nut, and the pull rod assembly and the pull rod hole on the rubber pad are in interference fit, so that on one hand, the pull rod assembly can pass through the part to be light-tight and airtight, and the better sealing effect is ensured; on the other hand, will produce wearing and tearing after long-term running-in between pull rod closes the piece and the rubber pad, and rubber pad after wearing and tearing will produce the clearance and make the pull rod hole increase and then destroy interference fit with the pull rod closes the piece, and the utility model discloses in adopt bolt cooperation nut to cover the clamp plate on the rubber pad, when producing the clearance, because the rubber pad has certain elasticity, produce the squeezing action to the rubber pad through the moment of torsion of adjusting lock nut for the rubber pad is to pull rod hole direction extrusion deformation, thereby makes the pull rod hole reduce and keeps the interference fit between rubber pad and the pull rod closes the piece, and the clearance that long-term wearing and tearing brought like this both can obtain the restoration, also provides the compensation for the rubber pad wearing and tearing, improves life.
