A protective device for a folding bicycle rod locking mechanism

Abstract

This invention discloses a protective device for the locking mechanism of a folding bicycle handlebar, belonging to the technical field of folding bicycle handlebars. It includes a protective sleeve and a locking ring. The protective sleeve consists of a C-shaped fixing sleeve and an arc-shaped insert plate disposed on the end face of the C-shaped fixing sleeve. The locking ring consists of a C-shaped locking ring and a quick-release buckle, which locks the C-shaped locking ring, the arc-shaped insert plate, and the handlebar together. By placing the protective sleeve above the folding point of the handlebar and the locking ring below the folding point, the bottom of the arc-shaped insert plate of the protective sleeve is locked to the handlebar, thus forming a rigid connection on the outside of the locking mechanism. This improves the rigidity of the folding point, reduces the stress on the locking mechanism, prevents breakage of the locking mechanism during vigorous riding, and avoids sudden damage to the handlebar. An arc-shaped washer is provided inside the cavity of the C-shaped locking ring; by replacing the arc-shaped washer with one of different thicknesses, the protective device can be adapted to different handlebar models.

Description

Technical Field

[0001] The invention relates to a protective device for a locking mechanism of a folding bicycle pole, belonging to the technical field of folding bicycle poles. Background Art

[0002] The difference between an electric scooter and an ordinary skateboard is that an electric scooter is driven by a motor, does not require physical effort, and can slide automatically. In order to save space, the handle of an electric scooter can generally be folded, which is called an electric scooter folding vehicle. Some existing electric scooters or other folding vehicles have design defects in the locking mechanism at the folding part of the handle. There will be no problems during normal driving, but when encountering intense riding, the hook of the locking mechanism at the folding part of the handle is easy to break, which will cause the handle structure to be suddenly damaged. Not only can the folding vehicle not drive normally, but the sudden damage may even cause personal injury.

[0003] Therefore, a protective device for a locking mechanism of a folding bicycle bar is designed. The protective device is installed at the folding part of the folding bicycle bar and is sleeved on the outside of the locking mechanism to serve as a reinforced connection of the locking mechanism and provide protection for the locking mechanism during intense riding. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a protective device for the locking mechanism of the folding bicycle pole, which solves the problem that when the folding bicycle is subjected to intense riding, the locking mechanism hook at the folding part of the pole is easy to break, resulting in sudden damage to the pole structure and endangering personal safety.

A locking screw hole is arranged at the interruption of the C-shaped fixing sleeve. The C-shaped fixing sleeve is sleeved on the vehicle rod above the folding part. The lower end of the arc-shaped insert plate extends below the folding part. The C-shaped fixing sleeve is locked and fixed to the vehicle rod by screwing a locking screw into the locking screw hole.

[0008] The locking ring is composed of a C-shaped locking ring and a quick-release buckle. A pair of mounting holes are provided at the interruption of the C-shaped locking ring, and a quick-release buckle is provided between the mounting holes.

DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0027] like Figure 1-Figure 5 As shown, a protective device for a locking mechanism of a folding bicycle rod comprises a protective cover 1 and a locking ring 2;

[0028] The protective cover 1 is composed of a C-shaped fixing cover 11 and an arc-shaped insert plate 12 arranged on the end surface of the C-shaped fixing cover 11. A locking screw hole 13 is arranged at the interruption of the C-shaped fixing cover 11. The C-shaped fixing cover 11 is sleeved on the vehicle rod 3 above the folding part. The lower end of the arc-shaped insert plate 12 extends below the folding part. The C-shaped fixing cover 11 is locked and fixed to the vehicle rod 3 by screwing a locking screw 14 into the locking screw hole 13.

[0029] The locking ring 2 is composed of a C-shaped locking ring 21 and a quick-release buckle 22. A pair of mounting holes 24 are provided at the interruption of the C-shaped locking ring 21, and the quick-release buckle 22 is provided between the mounting holes 24. An arc-shaped groove 23 corresponding to the arc-shaped plug plate 12 is provided in the cavity of the C-shaped locking ring 21. The C-shaped locking ring 21 is sleeved on the vehicle bar 3 below the folded part, and the arc-shaped groove 23 of the C-shaped locking ring 21 is sleeved on the arc-shaped plug plate 12. The C-shaped locking ring 21, the arc-shaped plug plate 12, and the vehicle bar 3 are locked and fixed by the quick-release buckle 22.

[0030] An arc-shaped gasket 4 is arranged in the cavity of the C-shaped locking ring 21, and a fixing ear hole 41 parallel to the end face of the C-shaped locking ring 21 is arranged on one side of the arc-shaped gasket 4. The fixing ear hole 41 of the arc-shaped gasket 4 is fixed to the end face of the C-shaped locking ring 21 by screws.

[0031] At least two arc-shaped inserting plates 12 are disposed on the end surface of the C-shaped fixing sleeve 11 .

[0032] The arc-shaped gasket 4 is arranged at the interruption of the C-shaped locking ring 21 .

[0033] The quick release buckle 22 is composed of a screw 221, a gasket 222, a nut 223, and a quick release handle 224. The head of the screw 221 is hinged to the quick release handle 224, and the other end passes through the gasket 222 and the installation hole 24 at the interruption of the C-shaped locking ring 21 in turn, and is tightened with the nut 223 on the other side.

[0034] A positioning screw hole 15 is provided on the side of the C-shaped fixing sleeve 11. A positioning screw 16 is screwed into the positioning screw hole 15 to fix the C-shaped fixing sleeve 11 to the vehicle rod 3 from the side.

[0035] The folding steps of the folding bicycle pole 3 installed with the present invention are as follows:

[0036] Step 1: If Figure 6 As shown, open the quick release buckle 22 on the C-shaped locking ring 21, take off the locking ring 2 downward, and release the arc-shaped plug plate 12 at the lower end of the C-shaped fixing sleeve 11;

[0037] Step 2: If Figure 7 As shown, the locking mechanism 5 at the folding position of the vehicle bar 3 is opened, and the vehicle bar begins to be folded. The protective cover 1 is fixed on the vehicle bar 3 above the folding position and is folded together with the vehicle bar 3 above.

[0038] It is only necessary to take off the locking sleeve 2 , and the protective device does not affect the normal folding of the vehicle bar 3 .

[0039] Working principle:

[0040] By arranging the protective cover 1 above the folding part of the bicycle bar 3, and putting the locking ring 2 below the folding part of the bicycle bar 3, the bottom of the arc-shaped plug plate 12 of the protective cover 1 is locked with the bicycle bar 3 through the locking ring 2, so as to form a rigid connection on the outside of the locking mechanism 5, which can improve the rigidity of the folding part, reduce the stress of the locking mechanism 5, prevent the locking mechanism 5 from breaking during intense riding, and avoid sudden damage to the bicycle bar 3;

[0041] An arc-shaped gasket 4 is arranged in the cavity of the C-shaped locking ring 21. By replacing the arc-shaped gasket 4 with different thicknesses, the protective device can be adapted to different types of vehicle rods 3, thereby expanding the applicable scope of the protective device.

[0042] The positioning screws 16 fix the C-shaped fixing sleeve 11 to the vehicle bar 3 from the side, further improving the fixing strength of the protective sleeve 1.

[0043] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention.
