Description

Technical Field

[0001] The present application relates to the field of front fork handlebar locking technology, and in particular to a handlebar locking device for an energy-saving power-assisted bicycle. Background Art

[0002] The existing front fork locking device on the market is locked by a hanging screw and a tungsten wire. Since the handlebar riser of a semi-recumbent tricycle has a bend and a universal joint in the middle, the device is not suitable for a semi-recumbent tricycle. Two new locking devices are needed to connect the universal joint to fix the handlebar and the front fork together to achieve the purpose of steering. Therefore, a new front fork locking device is designed to solve the problems existing in the prior art described above. Utility Model Content

[0003] The present application provides an energy-saving power-assisted bicycle handlebar locking device that adopts the following technical solution:

[0004] A handlebar locking device for an energy-saving power-assisted bicycle is characterized in that it includes: a steering extension rod, a locking upper seat, a tensioning ring, a bolt, a locking lower seat and a key strip. The locking upper seat and the locking lower seat are arranged in the tensioning ring and are respectively located at both ends of the tensioning ring. The steering extension rod is arranged at one end of the tensioning ring close to the locking lower seat. The tensioning ring and the steering extension rod are both provided with a key slot. The key strip is arranged in the key slot and connects the steering extension rod and the tensioning ring. The bolt passes through the steering extension rod, the locking upper seat and the tensioning ring in sequence and is threadedly connected and locked with the locking upper seat.

[0005] The energy-saving power-assisted bicycle handlebar locking device provided by the embodiment of the present disclosure can achieve the following technical effects:

[0006] The locking upper seat moves toward the tensioning ring as the bolt is tightened, expands the tensioning ring, and finally fixes the device on the inner wall of the front fork or handlebar vertical tube, thereby connecting the front fork and the handlebar with the universal joint to form a whole, and finally achieving the purpose of steering.

[0007] The above general description and the following description are exemplary and explanatory only and are not intended to limit the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0013] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, in the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0014] The following is combined with Figure 1-3 This application is described in further detail.

[0015] A handlebar locking device for an energy-saving power-assisted bicycle is characterized in that it includes: a steering extension rod 1, a locking upper seat 2, a tensioning ring 3, a bolt 4, a locking lower seat 6 and a key strip 5. The locking upper seat 2 and the locking lower seat 6 are arranged in the tensioning ring 3 and are respectively located at both ends of the tensioning ring 3. The steering extension rod 1 is arranged at one end of the tensioning ring 3 close to the locking lower seat 6. The tensioning ring 3 and the steering extension rod 1 are both provided with a key slot. The key strip 5 is arranged in the key slot and connects the steering extension rod 1 and the tensioning ring 3. The bolt 4 passes through the steering extension rod 1, the locking upper seat 2 and the tensioning ring 3 in sequence and is threadedly connected and locked with the locking upper seat 2.

[0016] During installation, put the lower stop seat 6 into one end of the tension ring 3, then place the steering extension rod 1 on the end of the tension ring 3 close to the lower stop seat 6, so that the key slots on the tension ring 3 and the steering extension rod 1 are aligned, and then knock the key bar 5 into the key slot and connect the steering extension rod 1 and the tension ring 3. Then put the upper stop seat 2 on the other end of the tension ring 3, and pass the bolt 4 through the steering extension rod 1, the upper stop seat 2 and the tension ring 3 in turn and connect and lock it with the upper stop seat 2. At this time, the upper stop seat 2 moves into the tension ring 3 as the bolt 4 is locked, and the tension ring 3 is expanded, and finally the device is fixed on the inner wall of the front fork or the handlebar vertical tube, so as to connect the front fork and the handlebar with the universal joint as a whole, and finally achieve the purpose of steering.

[0017] In one embodiment, a gear is provided at one end of the steering extension rod 1 away from the tensioning ring 3, and the gear is connected and fixed to the joint of the universal joint.
