Description

Technical Field

[0001] The invention relates to the technical field of bicycle handlebars, in particular to a foldable handlebar. Background Art

[0002] At present, existing bicycle handlebars often use an integrated tube body and cannot be folded, which brings certain problems to the transportation of bicycles. When the handlebars are installed on the body, the space required for bicycle transportation will be larger, which is inconvenient to transport. Therefore, when transporting bicycles, manufacturers generally do not install the handlebars on the body, and consumers are required to assemble the handlebars by themselves, and the manufacturer provides assembly guidance. On the one hand, this increases the burden on consumers, and on the other hand, it also increases the after-sales burden on manufacturers. Summary of the invention

[0003] The purpose of the present invention is to solve the problem of inconvenience in bicycle transportation caused by the existence of handlebars, and to provide a foldable handlebar. After the handlebar is installed on the bicycle body, the handlebar can be folded and shipped, which reduces the assembly burden of consumers and the after-sales burden of manufacturers.

[0004] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0005] A foldable handlebar comprises a handlebar body and a safety rod inserted into the handlebar body and detachably connected to the handlebar body, a locking mechanism is provided between the safety rod and the handlebar body, and the handlebar body comprises a central tube body and folding tubes arranged at the left and right ends of the central tube body and hinged to the central tube body.

[0006] Preferably, the central tube body includes a first circular tube and a first square tube arranged at the left and right ends of the first circular tube. The first square tube is provided with a tube avoidance hole adapted to the folding tube on the outer wall away from the first circular tube, and the hinge between the central tube body and the folding tube is located on the first square tube.

[0007] Preferably, the folding tube includes a second square tube hinged to the first square tube through a hinge and a second circular tube arranged at one end of the second square tube away from the first square tube.

[0008] Preferably, the hinged part is a bolt, and the safety rod includes two rod units, each of which includes a main support portion and an auxiliary support portion provided at one end of the main support portion. The two rod units are centrally symmetrically arranged, and avoidance holes adapted to the bolts are formed in the middle of the two rod units.

[0009] Preferably, the cross section of the overlap between the main support portion of one rod unit and the auxiliary support portion of another rod unit is a circular cross section adapted to the cross section of the second circular tube.

[0010] Preferably, the locking mechanism comprises a spring buckle arranged on the safety rod, and a through hole adapted to the spring buckle is provided on the outer wall of the handlebar body.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The central tube body of the handlebar body of the present invention is hinged with the folding tube, and the folding tube can be rotated 90 degrees, so that the handlebar body can be folded as a whole, which can reduce the space occupied by the handlebar; the safety rod is inserted into the handlebar body and is detachably connected to the handlebar body. When the axis center lines of the central tube body and the folding tube coincide with each other, the safety rod can be inserted into the handlebar body, and the handlebar body is maintained in a horizontal state through the safety rod. The locking mechanism can prevent the safety rod from falling off the handlebar body, thereby ensuring safety during use; after the safety rod is removed from the handlebar body, the folding tube can be rotated 90 degrees, so that the handlebar body is in a folded state, reducing the space occupied when installed on the bicycle body, facilitating transportation, and solving the problem of inconvenience in bicycle transportation caused by the existence of the handlebar. After the handlebar is installed on the bicycle body, the handlebar can be folded and shipped, which reduces the assembly burden of consumers and also reduces the after-sales burden of manufacturers.

[0018] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the application equally.

[0019] Example: As shown in the attached Figure 1-4As shown, the present invention is a foldable handlebar, comprising a handlebar body and a safety rod inserted into the handlebar body and detachably connected to the handlebar body, a locking mechanism is provided between the safety rod and the handlebar body, the handlebar body comprises a central tube body 1 and folding tubes 2 arranged at the left and right ends of the central tube body 1 and hinged to the central tube body 1, the folding tube 2 can rotate at least 90 degrees, the folding tube 2 can be adjusted from a state parallel to the central tube body 1 to a state perpendicular to the central tube body 1, when the folding tube 2 is parallel to the central tube body 1, the safety rod is passed through the folding tube 2 on the left from left to right in sequence, Tube 2, central tube body 1, and the folding tube 2 on the right can prevent the handlebar body from being deformed. The safety rod can be locked in the handlebar body by a locking mechanism to ensure the stability of the present invention when in use. After the safety rod is removed from the handlebar body, the folding tube 2 is rotated 90 degrees to put the handlebar body in a folded state, thereby reducing the space occupied when installed on the vehicle body and facilitating transportation. This solves the problem of inconvenience in transporting bicycles caused by the presence of the handlebar. After the handlebar is installed on the vehicle body, it can be folded and shipped, which reduces the assembly burden of consumers and the after-sales burden of manufacturers.
