Description

Technical Field

[0001] This utility model relates to the field of sealing plug technology, specifically to a sealing plug for a driver's cab. Background Technology

[0002] With the development of the domestic harvester market, users have increasingly higher requirements for modern agricultural machinery. While ensuring high quality, it is also necessary to meet user needs as much as possible, and improving user driving comfort is a crucial aspect of this. The sealing issue has the greatest impact on the driver, but current solutions for cab sealing are not perfect. Most systems only offer partial sealing, which is costly and ineffective, allowing dust and noise to enter the cab, severely reducing comfort and providing a poor driving experience. The cab frame is welded from several irregularly shaped tubes. If the joints of these tubes are not sealed, dust will enter the cab, affecting the driver's experience. Therefore, it is essential to ensure that the joints of these tubes are completely sealed. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the purpose of this invention is to provide a sealing plug for a driver's cab, solving the problem of dust entering the cab due to unsealed pipe openings at the joints of irregularly shaped pipes.

[0004] This utility model is achieved through the following technical solution:

[0005] A sealing plug for a driver's cab includes a cover plate and a side frame. The cover plate and the side frame are perpendicularly arranged and form a cover shape. The side frame is fitted into the inner wall of the bottom of a shaped tube. The shaped tube is located at the four corners of the driver's cab frame. The shaped tube includes a rectangular frame portion that overlaps the side wall of the driver's cab and a convex column portion with rounded corners. The shape of the side frame is constructed along the cross-section of the bottom of the shaped tube, and correspondingly includes a rectangular portion and a convex circular portion. A rounded corner is provided between the rectangular portion and the convex circular portion for a smooth transition. The shape of the cover plate is consistent with the shape of the side frame and extends uniformly outward from the side frame, completely covering the bottom of the shaped tube. A wire through hole is provided in the corresponding convex circular portion area of ​​the cover plate.

[0006] Preferably, a wire hole cover is fitted around the inner wall of the wire hole.

[0007] Preferably, the side frame is made of a flexible material.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] This invention uses a sealing plug with the same cross-sectional shape as the bottom of a shaped tube, and its side frame is fitted into the inner wall of the bottom of the shaped tube, thereby preventing dust from entering the cab at the tube opening, ensuring a reliable seal. The cover plate has a wire hole for the air conditioning pipe to pass through the shaped tube, and a wire hole cover is used to block and seal the dust around the hole. This invention has a simple design and low cost. Attached Figure Description
