Abstract
Description
Technical Field
[0001] This utility model relates to the field of bicycle accessories technology, and more specifically, to a bicycle front fork handlebar. Background Technology
[0002] The front fork is located at the front of the bicycle structure. Its upper end is connected to the handlebar assembly, the frame assembly mates with the head tube, and its lower end mates with the front axle assembly, forming the bicycle's steering system.
[0003] Existing technologies disclose some patent documents related to bicycle forks. Chinese patent application number CN202221809127.4 discloses a quick-release and disassembly structure for a bicycle stem and fork, including a head tube. A fork is internally connected to the head tube, and a fork stem is located at the top of the fork. A positioning groove is engaged internally by a third locking pin in the fork stem. A stop is located at the bottom of the positioning groove, and the bottom of the stop contacts the top of a spring, which is placed inside the fork stem. A positioning post is engaged internally in the positioning groove, and the middle of the positioning post engages with one end of a first locking pin. The other end of the first locking pin engages internally with one end of the stem. This invention has a simple structure, allowing for quick installation and disassembly of the stem, head tube, and fork without the need for any tools. It is simple to operate, reduces the disassembly and assembly process, lowers costs, and improves efficiency, ensuring both convenience and reliability of the assembled components.
[0004] In the aforementioned patent, the front fork handlebar uses a single threaded connection, resulting in poor installation stability. Therefore, we propose a bicycle front fork handlebar. Utility Model Content
[0005] 1. Technical problems to be solved
[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide a bicycle front fork handlebar. This utility model uses a stud threaded connection to a threaded hole. The rotation of the stud causes it to move upward within the threaded hole. The upward movement of the stud simultaneously pushes two inclined plates to move outward. The movement of the inclined plates pushes the vertical plate and the insert block to move outward, thereby allowing the insert block to be inserted into the insertion hole. The engagement between the insert block and the insertion hole facilitates the installation of the upright and the front fork body together, further optimizing the stability of the frame head tube, handlebar, and front fork body during installation.
[0007] 2. Technical Solution
[0008] To solve the above problems, the present invention adopts the following technical solution:
[0009] A bicycle front fork handlebar, comprising:
[0010] Frame head tube;
[0011] The handlebars are mounted on the head tube of the frame. A post is fixedly connected to the bottom of the handlebars. The post is movably inserted into the head tube of the frame and is threadedly connected to the head tube of the frame.
[0012] The fork body is threaded to the bottom of the head tube of the frame and is in contact with the column.
[0013] A fixing mechanism is provided on the front fork body and is connected to the upright.
[0014] In a preferred embodiment of this utility model, the fixing mechanism includes a movable component and two sets of locking components, both of which are disposed on the front fork body and are connected to each other.
[0015] In a preferred embodiment of this utility model, the moving component includes a threaded hole and a stud, the threaded hole being formed on the fork body, and the stud being threadedly connected to the bottom of the threaded hole.
[0016] As a preferred embodiment of this utility model, each set of the snap-fit components includes a mounting groove, a socket, a slide plate, a spring, a vertical plate, a plug, and a ramp. The mounting groove is formed on the front fork body, the socket is formed on the upright, the slide plate is slidably connected in the mounting groove, the spring is fixedly connected between the mounting groove and the slide plate, the vertical plate is fixedly connected to the slide plate, the plug is fixedly connected to the outside of the vertical plate and is movably inserted into the socket, and the ramp is fixedly connected to the inside of the vertical plate.
[0017] As a preferred embodiment of this utility model, guide rods are fixedly connected to both of the mounting slots, and the two sliding plates are slidably connected to the surfaces of the two guide rods respectively.
[0018] In a preferred embodiment of this utility model, the two springs are respectively located on the surfaces of the two guide rods.
[0019] 3. Beneficial effects
[0020] Compared with existing technologies, the advantages of this utility model are:
[0021] (1) When the head tube, handlebars and fork body need to be installed, the upright is first inserted into the head tube and the upright is threaded to the top of the head tube. Then the fork body is threaded to the bottom of the head tube. At this time, the upright and the fork body are in contact. Then the stud is threaded into the threaded hole. The stud moves upward in the threaded hole by rotating. The upward movement of the stud pushes the two swashplates to move outward. The movement of the swashplates pushes the vertical plate and the insert to move outward, so that the insert is inserted into the socket. The snap-fit between the insert and the socket makes it easy to install the upright and the fork body together, further optimizing the stability of the head tube, handlebars and fork body during installation.
[0022] (2) In this scheme, the guide rod is fixed to facilitate the sliding connection with the skateboard. The sliding cooperation between the guide rod and the skateboard facilitates the stable movement of the skateboard. Attached Figure Description
