DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-6 The utility model provides a technical solution: a new type of tractor cab wiring harness sealing structure, including: a sealing box 1, a wiring harness mounting head 2, a sealing guide rod 3, a first spring 4, a wiring harness bin 5, a guide roller 6, a slide bar 7, a second spring 8, a mounting bin 9, a connecting groove 10, a connecting rod 11, a third spring 12, a pressing block 13, a hinged rod 14, a limiting rod 15, and a mounting block 16.

[0028] First, as attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 and attached Figure 4As shown in , when the wiring harness is installed, the wiring harness is first inserted into the interior of the upper wiring harness installation head 2 in the sealing box 1. Since the sealing guide rod 3 is arranged in an inclined state with respect to one end of the interior of the wiring harness installation head 2, the wiring harness drives the sealing guide rod 3 to slide in the interior of the wiring harness installation head 2, and at the same time, the wiring harness drives the first spring 4 sleeved on the outer side of the sealing guide rod 3 to be compressed, so that the sealing guide rod 3 and the wiring harness are fitted and connected together. At the same time, the sealing guide rod 3 is arranged in a circular array state with respect to the central circle of the wiring harness installation head 2, so that the fitting between the sealing guide rod 3 and the first spring 4 can provide a good sealing state. Since the wiring harness installation head 2 and the wiring harness bin 5 are arranged in a connected state, the wiring harness passes through the wiring harness installation head 2 and enters the interior of the wiring harness bin 5;

[0029] As attached Figure 1 and attached Figure 2 As shown in the figure, after the wire harness enters the interior of the wire harness bin 5, the guide rollers 6 at the left and right ends of the wire harness bin 5 are arranged in a corresponding state, so that the wire harness and the guide rollers 6 at the left and right ends of the wire harness bin 5 are fitted together. When the wire harness slides inside the wire harness bin 5, the upper sliding rod 7 in the wire harness bin 5 is slidably connected to the upper end of the guide roller 6, and the lower sliding rod 7 in the wire harness bin 5 is slidably connected to the lower end of the guide roller 6, so that the diameter of the wire harness drives the guide roller 6 to slide on the rod body of the sliding rod 7, thereby making the guide roller 6 The roller 6 compresses the second spring 8 sleeved on the outer side of the slide bar 7, so that the elastic force of the second spring 8 drives the guide roller 6 to slide inside the wire harness bin 5, so that the guide roller 6 fixes the wire harness, and the wire harness and the guide roller 6 are fitted together. When the wire harness slides inside the wire harness bin 5, the wire harness drives the guide roller 6 to rotate, so that the wire harness passes through the wire harness bin 5, and also passes through the lower wire harness installation head 2 in the sealing box 1, so as to prevent the wire harness from loosening or colliding, and also ensure that the wire harness is correctly arranged to avoid crossing;

[0030] As attached Figure 2 , Attachment Figure 3 , Attachment Figure 5 and attached Figure 6As shown in the figure, after the wiring harness is installed, since the mounting block 16 is fixedly installed at any position of the tractor cab, the sealing box 1 can be installed on the mounting block 16, so that the mounting block 16 is placed between the mounting bins 9 at the left and right ends of the sealing box 1, so that the limiting rod 15 on the mounting bin 9 is fitted with the side wall of the mounting block 16, so that the mounting block 16 drives the limiting rod 15 to slide inside the mounting bin 9, and then is rotatably connected with the limiting rod 15 and the upper end of the connecting rod 11 in an inclined state through the hinge rod 14, so that the limiting rod 15 drives the connecting rod 11 in the connecting bin through the hinge rod 14. The internal sliding of the connecting groove 10 also causes the connecting rod 11 to drive the third spring 12 inside the connecting groove 10 to be compressed. When the mounting bin 9 slides to a certain position on the rod body of the mounting block 16, the elastic force of the third spring 12 drives the connecting rod 11 to form a lifting structure. At the same time, the connecting rod 11 also drives the pressing block 13 to slide on the side wall of the mounting bin 9, and then the connecting rod 11 drives the limiting rod 15 through the hinged rod 14 to form a telescopic structure, so that the limiting rod 15 and the mounting block 16 are engaged together, thereby ensuring correct installation at the specified position.
