Description

Technical Field

[0001] The utility model relates to a flexible tarpaulin fixer, belonging to fixed parts. Background Art

[0002] Among the current domestic three-wheel electric vehicle models, some have a fixed cab frame structure, and this type of vehicle has no doors. The cab frame can block sunlight and wind and rain.

[0003] However, the lack of doors in the cab frame causes the drivers and passengers to be exposed to the wind on windy days, presenting certain safety hazards and being not very user-friendly to the drivers and passengers.

[0004] Installing doors requires modifying the cab frame, which also involves changes to the fixed structure and may damage the cab frame structurally.

[0005] To protect from wind and rain, installing a flexible tarpaulin can solve the problem of wind and rain. However, as for how to fix the tarpaulin to the existing cab frame structure, currently it is all fixed by drilling holes and threading ropes, which is rather difficult for consumers. Content of the Utility Model

[0006] The utility model provides a flexible tarpaulin fixer to solve the problem of fixing a flexible tarpaulin used as a shielding curtain for the cab frame of an electric tricycle.

[0007] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0008] A flexible tarpaulin fixer,

[0009] comprising an outer fixing cylinder and an inner fixing cylinder. A slot is provided on the side surface of the outer fixing cylinder, penetrating through the outer wall to both end holes;

[0010] The inner fixing cylinder is embedded in the outer fixing cylinder. A screw hole is formed on the side wall of the outer fixing cylinder on one side of the slot, and a hand-tightening bolt is arranged in the screw hole. The end of the hand-tightening bolt abuts against the inner fixing cylinder. The flexible tarpaulin and the thin-layer mechanism of the fixing parts are inserted into the outer fixing cylinder from the slot, and the outer axial surface of the inner fixing cylinder abuts against the flexible tarpaulin and the thin-layer mechanism of the fixing parts to fix the flexible tarpaulin and the thin-layer mechanism of the fixing parts.

[0011] According to the flexible tarpaulin fixer described above, the thin-layer mechanism of the fixing parts is the edge structure of the doorless roof of a three-wheel electric vehicle. An arc-shaped water trough is formed by the downward depression on the inner side of this edge structure. The side of the screw hole of the outer fixing cylinder faces upward, and the flexible tarpaulin and the thin-layer mechanism of the fixing parts are inserted between the lower side surface of the inner fixing cylinder and the inner wall of the outer fixing cylinder.

[0012] According to the flexible tarpaulin fixer described above, the outer fixing cylinder and the inner fixing cylinder are made of metal pipe fittings, and the edges of the slot of the outer fixing cylinder are rounded and polished smoothly.

[0013] According to the flexible tarpaulin fixator described above, a positioning concave is provided on the inner fixing cylinder towards the side of the screw hole, and the bottom surface of the positioning concave is a plane.

[0014] According to the flexible tarpaulin fixator described above, it is characterized in that a through hole is provided on the inner fixing cylinder towards the side of the screw hole, the end of the bolt passes through the through hole, and limits are respectively arranged on the inner and outer sides of the inner fixing cylinder, and the bolt can rotate in the through hole of the bolt cylinder.

[0015] The advantages of the present utility model are as follows:

[0016] The flexible rainproof tarpaulin is fixed to the top edge of the tricycle canopy by extrusion, and the effective fixation can prevent the rainproof tarpaulin from falling off;

[0017] By fixing the device with standardized bolts, the fixing speed is fast, and it is convenient for disassembly, replacement and maintenance. Description of the Drawings

Detailed Embodiments

[0024] The content of the present utility model will be further described below:

[0025] The specific content of the present utility model will be further described below:

[0026] The flexible tarpaulin fixator of the present utility model includes an outer fixing cylinder 1 and an inner fixing cylinder 2. A slot 11 is provided on the side of the outer fixing cylinder 1, which penetrates the outer wall to both end holes.

[0027] In this device, the fixed cylinder 2 is embedded in the outer fixed cylinder 1. On the side wall of the outer fixed cylinder 1 on one side of the slot 11, a screw hole 12 is opened. A hand-tightening bolt 3 is arranged in the screw hole 12. The end of the hand-tightening bolt 3 abuts against the fixed cylinder 2. The flexible tarpaulin and the thin-layer mechanism of the fixing parts are inserted into the outer fixed cylinder 1 from the slot 11. The outer axial surface of the fixed cylinder 2 abuts against the flexible tarpaulin and the thin-layer mechanism of the fixing parts to fix the flexible tarpaulin and the thin-layer mechanism of the fixing parts.

[0028] The thin-layer mechanism of the fixing parts of this device is the edge structure of the roof without doors of a three-wheeled electric vehicle. The inner side of this edge structure is concave to form an arc-shaped water chute. The side of the screw hole 12 of the outer fixed cylinder 1 faces upward. The flexible tarpaulin and the thin-layer mechanism of the fixing parts are inserted between the lower side of the fixed cylinder 2 and the inner wall of the outer fixed cylinder 1.

[0029] The outer fixed cylinder 1 and the fixed cylinder 2 are made of thin metal pipe fittings. The edges of the slot 11 of the outer fixed cylinder 1 are chamfered and polished smoothly to avoid scratching and damaging the tarpaulin and causing it to rupture.

[0030] On the side of the fixed cylinder 2 of this device facing the screw hole 12, a positioning concave 21 is provided. The bottom surface of the positioning concave 21 is a plane. The bolt is embedded in this positioning concave to prevent sliding when fixing the fixed cylinder.

[0031] Or on the side of the fixed cylinder 2 of this device facing the screw hole 12, a through hole is provided. The end of the bolt passes through this through hole and limits are respectively set on the inner and outer sides of the fixed cylinder 2. The bolt can rotate in the through hole. This structure can prevent the separation between the fixed cylinder and the hand-tightening bolt and improve the fixing effect.

[0032] This device can fix all the edge positions of the tarpaulin at the edges of the roof without doors of a three-wheeled electric vehicle, avoiding the sagging of the clamping positions. The fixing effect is good.

[0033] This utility model can effectively fix the flexible tarpaulin at the door of the tricycle shed frame with a water chute, realizing the effective fixing of the flexible curtain; it is suitable for the installation of the flexible curtain of the existing tricycle shed frame.
