Description
Technical Field
The utility model relates to the technical field of power equipment, in particular to a seat mistake-proofing dismounting structure.
Background
The lawn vehicle seat is usually fastened by a step bolt, the bolt step is tightly pressed with the side surface of a seat mounting support lug to realize fastening, and the free rotation of the seat can be realized through a gap between a step shaft and a seat bottom plate hole. However, the existing technical scheme has the following defects: the bolt step may press against the seat pan during assembly rather than the seat lugs, causing the seat to fail to rotate, or the bolt reverse installation may also cause the seat to become locked, again causing the seat to fail to rotate.
SUMMERY OF THE UTILITY MODEL
In view of the above problems, the present invention is directed to a seat mis-assembly/disassembly prevention structure for preventing mis-assembly of a seat.
In order to solve the problems in the prior art, the technical scheme provided by the utility model is as follows:
a seat mistake proofing attaching and detaching structure comprising:
the frame is fixed with two oppositely arranged seat support lugs;
the seat bottom plate is fixed with bushings at two ends respectively; and
the step bolt, it wears to establish in proper order on bush, seat bottom plate and the seat journal stirrup, the fenestrate aperture on the seat journal stirrup is less than the external diameter of step portion of step bolt, the step bolt via locknut fastening is in on the seat journal stirrup, just seat extension board, bush with the step portion normal running fit of step bolt.
Furthermore, the seat support lug is arranged on the frame along the vertical direction, the seat bottom plate comprises a first plate at the middle part and a second plate arranged at two ends of the first plate and arranged downwards along the vertical direction, and the bushing is fixed on the second plate and axially extends along the horizontal direction.
Further, the bushing is fixed on one side of the second plate, which is far away from the first plate, and the seat support lug is arranged on one side of the second plate, which is close to the first plate.
Further, the axial length of the step part of the step bolt is greater than the sum of the axial length of the bushing and the thickness of the second plate.
Compared with the prior art, the utility model has the advantages that:
the lining is arranged on the seat bottom plate, so that the situation that the seat cannot rotate due to the fact that the step part of the step bolt abuts against the seat bottom plate can be avoided; the aperture of the through hole on the seat support lug is smaller than the outer diameter of the step part of the step bolt, so that the error installation of the step bolt can be avoided, and the installation efficiency is improved.

Detailed Description
The above-described scheme is further illustrated below with reference to specific examples. It should be understood that these examples are for illustrative purposes and are not intended to limit the scope of the present invention. The conditions used in the examples may be further adjusted according to the conditions of the particular manufacturer, and the conditions not specified are generally the conditions in routine experiments.
Referring to fig. 1-2, a schematic structural diagram of an embodiment of the present invention provides a seat mistake-proofing dismounting structure, which includes a frame 1, a seat bottom plate 3, and a step bolt 5, two seat lugs 2 are fixed on the frame 1, the two ends of the seat bottom plate 3 are respectively fixed with a bushing 4, the step bolt 5 sequentially penetrates through the bushing 4, the seat bottom plate 3, and the seat lugs 2, the aperture of a through hole on the seat lug 2 is smaller than the outer diameter of a step portion 5-1 of the step bolt 5, the step bolt 5 is fixed on the seat lug 2 via a locknut 6, and the seat bottom plate 3, the bushing 4 are rotationally matched with the step portion 5-1 of the step bolt 5.
In this example, the seat bottom plate 3 includes a first plate 3-1 in the middle and a second plate 3-2 disposed at both ends of the first plate 3-1 and disposed downward in the vertical direction on the frame 1 where the seat lugs 2 are disposed in the vertical direction, the first plate 3-1 is connected to a slide rail assembly 7 on the seat 8, and the bushing 4 is fixed on the second plate 3-2 and extends axially in the horizontal direction. In order to facilitate free rotation of the seat 8, the axial length of the stepped portion 5-1 of the stepped bolt 5 is greater than the sum of the axial length of the bushing 4 and the thickness of the second plate 3-2.
For the convenience of installation, the bush 4 is fixed on the side of the second plate 3-2 far away from the first plate 3-1, the seat support lug 2 is arranged on the side of the second plate 3-2 near the first plate 3-1, and the step bolt 5 is installed through the outer side of the second plate 3-2.
Referring to fig. 3, when the seat is installed, the step bolt 5 is inserted into the bushing 4, the seat pan 3 and the seat support lug 2 in sequence, and when the threaded portion of the step bolt 5 is inserted into the seat support lug 2, the step portion 5-1 is inserted into the bushing 4, so that the step portion 5-1 of the step bolt 5 does not abut on the seat pan 3 and the seat 8 cannot rotate. Referring to fig. 4, when misloading occurs, the step portion 5-1 of the step bolt 5 abuts on the seat stay 2 not to be inserted through the seat stay 2, thereby preventing misloading from occurring.
The above examples are only for illustrating the technical idea and features of the present invention, and the purpose of the present invention is to enable those skilled in the art to understand the content of the present invention and implement the present invention, and not to limit the protection scope of the present invention.
