Locomotive fixed support structure

Abstract

This invention provides a motorcycle mounting bracket structure, comprising a frame including a base frame and a top frame. The base frame and top frame have signboard mounting units at each corner, creating an internal space between them. Each signboard mounting unit has corresponding guide slots for quick insertion and positioning of advertising signs. One end of the base frame has a multi-point positioning unit, including a first positioning element, a second positioning element, a third positioning element, and a support pad. Multiple locking rods and positioning ropes work together to securely fix the frame to the motorcycle's seat and armrests. The multi-point support configuration at the front, rear, and center effectively distributes stress and improves overall stability, preventing swaying or displacement during operation. Therefore, this motorcycle mounting bracket structure, through its multi-point positioning design, adjustable clamping mechanism, and quick signboard insertion structure, not only effectively improves stability and applicability but also offers practical advancements in advertising display and cargo carrying functions.

Claims

1. A locomotive fixing bracket structure, comprising a frame body, the frame body comprising: a bottom frame having four bottom frame supports forming a rectangular frame, and a crossbar provided at a predetermined position; and a top frame having four top frame supports forming a rectangular frame; wherein, The base frame and the top frame define a plurality of corner ends at each corner. A signboard unit is longitudinally arranged on the outer side of each corner end, allowing the base frame and top frame to be spaced apart and elevated by these signboard units, thus forming an internal space. Each signboard unit includes two mounting frames, respectively located on both sides of the corner end. Each mounting frame forms a U-shaped guide groove, with the opening of the guide groove facing the inner side of the frame, so that adjacent guide grooves correspond to each other. An advertising sign is inserted and positioned; one end of the base frame is provided with a multi-point positioning unit for fixing to a motorcycle seat. The multi-point positioning unit is located on one side of the base frame and includes two first positioning parts, two second positioning parts, a third positioning part, and a support pad; and a plurality of fastening rods are provided at the two corners of the base frame and the two corners of the cross frame. Each end of the fastening rod is provided with a connecting part, and each connecting part is respectively provided on the base frame and the cross frame, forming a fastening area.

2. The locomotive fixing bracket structure as described in claim 1, wherein a stop block is provided on the bottom surface of each corner end of the base frame, the stop block having a limiting surface corresponding to the bottom end of the guide groove to limit the insertion depth of the advertising stand.

3. The locomotive fixing bracket structure as described in claim 1, wherein each of the mounting brackets is integrally formed from an inner slot frame, a connecting section and an outer slot frame, one end of the inner slot frame is bent to connect to the connecting section, and the other end of the connecting section is bent to connect to the outer slot frame.

4. The locomotive fixing bracket structure as described in claim 1, wherein each of the first positioning members includes a first positioning block, the first positioning block having a first connecting portion and fixed to both sides of one end of the bottom of the base frame, each of the first positioning blocks having a first through hole for a first screw to pass through, and one end of the first screw having a first abutment, the two first positioning blocks being arranged in an outward V-shape; each of the second positioning members includes a second positioning block, the second positioning block having a second connecting portion, fixed to the base frame adjacent to the first positioning member and respectively disposed on both sides of the crossbeam, also arranged in an outward V-shape, each of the second positioning blocks having a second through hole for a second screw to pass through, and one end of the second screw having a second abutment; each of the third positioning members includes a third positioning block, the third positioning block having a third connecting portion, and Fixed to the base frame and located between the two first positioning members, and inclined towards the center, each of the third positioning blocks has a third through hole for a third screw to pass through. One end of the third screw has a third abutment. The first screws are respectively screwed with two first nuts corresponding to the first positioning blocks, the second screws are respectively screwed with two second nuts corresponding to the second positioning blocks, and the third screws are respectively screwed with two third nuts corresponding to the third positioning blocks. In use, the corresponding first abutment, second abutment, and third abutment can be rotated by loosening the corresponding first nuts, second nuts, and third nuts. The first abutment, second abutment, and third abutment are all of the rotary handle type structure, which presses against the rear side of the locomotive seat at a fixed point, and the clamping distance of the first positioning members, second positioning members, and third positioning members can be adjusted.

5. The locomotive fixing bracket structure as described in claim 1, wherein the two first positioning members are used to abut against the rear side edge of the locomotive seat; the two second positioning members are used to abut against the front side edge of the locomotive seat; the support pad is used to abut against the middle of the locomotive seat; and the third positioning member is used to abut against the rear position of the locomotive seat.

6. The locomotive fixing bracket structure as described in claim 1, wherein the locomotive is provided with a front handrail and a rear handrail at the front and rear positions of the fastening area corresponding to the fastening rods, and a positioning rope can be wrapped around the front handrail and the rear handrail; the two ends of the positioning rope are respectively provided with hooks for fastening to the fastening rods.

7. The locomotive mounting structure as described in claim 1, wherein the internal space is available for accommodating a storage box.
