Detailed Description

In order to make the technical problems, technical solutions and advantageous effects to be solved by the present application clearer, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly or indirectly connected to the other element.

It will be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like, refer to an orientation or positional relationship illustrated in the drawings for convenience in describing the present application and to simplify description, and do not indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the present application.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.

A quick-release type handlebar tube connecting device is disclosed, referring to fig. 1 to 3, and comprises a vertical tube 1 and an anchor ear 11 which extends outwards along the vertical tube 1 and clamps a handlebar tube, wherein a pre-locking assembly 2 for locking and unlocking the handlebar tube is arranged on one side of the anchor ear 11, and a locking mechanism 3 for further locking and unlocking the pre-locking assembly 2 is arranged on the vertical tube 1.

The handlebar pipe peg graft in staple bolt 11, treat after the handlebar pipe is transferred to suitable position, earlier through the preliminary fixed with the handlebar pipe of pre-lock subassembly 2, the rethread will be locked mechanism 3 with the pre-lock and fix extremely, guarantee the quick installation of handlebar pipe with this, and on the same hand, treat that it is perhaps not hard up to dismantle the handlebar pipe, only need to with locking mechanism 3 unblock, rethread not hard up pre-lock subassembly 2, realize the quick dismantlement of handlebar pipe just so, just compare traditional bolt and nut's connected mode, not only convenient to use person realizes the self-dismounting fast, and can solve the easy rotten drawback of bolt and nut, do further guarantee for car owner's the riding.

Specifically, the pre-locking assembly 2 comprises a screw 21 penetrating through the hoop 11 and in threaded connection with the locking mechanism 3, and a nut 22 is arranged at one end, far away from the locking mechanism 3, of the screw 21.

The pre-locking assembly 2 realizes the tightness of the hoop 11 by twisting the screw 21, and the screw 21 is twisted by hands of a user by utilizing the arrangement of the screw cap 22.

Specifically, the locking mechanism 3 comprises a connecting rod 31 rotatably connected to the stand pipe 1 and an eccentric wheel structure 32 rotatably connected to the connecting rod 31, and the connecting rod 31 is in threaded connection with the pre-locking assembly 2.

The eccentric turns, causing a difference in the section in contact with the surface of the stem 1, thus pulling the connecting rod 31 and the tightness between the screw 21 and the stem 1, for the convenience of the user.

Specifically, the eccentric wheel structure 32 extends outwards to form a handle 33. The handle 33 is designed to facilitate rotation of the eccentric wheel and manual adjustment.

Specifically, the side of the vertical pipe 1 is provided with a mounting groove 34 for accommodating the locking mechanism 3. By means of the installation groove 34, installation and hiding of the locking mechanism 3 are facilitated, and meanwhile the overall attractiveness of the handlebar tube connecting device is effectively improved. And a gasket 6 is arranged between the mounting groove 34 and the eccentric wheel mechanism to prevent the friction loss of the inner wall of the mounting groove 34.

Specifically, the end of the stand pipe 1 is provided with an inclined surface 4. The inclined surface 4 is arranged, so that the abrupt arrangement between the hoop 11 and the stand pipe 1 can be eliminated, the ornamental value of the end part of the whole stand pipe 1 is improved, and when the side edge of the handle 33 is tightly attached to the inner wall of the installation groove 34, the surface of the handle 33 is flush with the surface of the inclined surface 4.

Specifically, the riser 1 is provided with a limiting assembly 5 for limiting the displacement of the handle 33. By means of the limiting assembly 5, the phenomenon that in the riding process, due to the vibration of the stand pipe 1, the handle 33 is loosened, and therefore the displacement of the eccentric wheel structure 32 is influenced is avoided.

Specifically, the limiting component 5 includes a bolt 51 sliding in the stand pipe 1 and a limiting groove 52 arranged on one side of the handle 33, and a spring 7 is sleeved on one side of the bolt 51; when the handle 33 presses the plug 51, the plug 51 is connected with the limiting groove 52 in cooperation with the pressing of the spring 7.

In the embodiment, after the screw 21 is rotated by the nut 22 to pre-lock the hoop 11, the handle 33 rotates the eccentric wheel structure 32 to lock the hoop 11 for the second time, and then the plug 51 is squeezed by the handle 33, so that the spring 7 is elastically deformed, and after the plug 51 is deviated to one side, the plug 51 returns under the pulling of the spring 7, and is inserted into the limiting groove 52 on one side of the handle 33, so as to limit the displacement of the handle 33.

The above-mentioned embodiments are merely illustrative and not restrictive, and those skilled in the art can make modifications to the embodiments without inventive contribution as required after reading the present specification, but only protected by the patent laws within the scope of the claims of the present application.
