Description

Handlebar clamping device

The utility model relates to a handlebar clamping device applied to a bicycle. Background technique

The traditional bicycle handlebar is fixedly connected with the vertical pipe. The structure can not adjust the position of the handlebar according to the user's needs or preferences, such as the height of the lower part, the front and rear position, the angle of the handlebar and the horizontal plane, and thus cannot meet the market demand. There are some adjustment devices for adjustable handlebars on the market. Chinese Patent No. 01271320.1 discloses a handlebar. The top of the standpipe is provided with a bundle of rings. The bolts pass through the sides of the bundle ring, and the upper end of the bolt is hinged with an eccentric locking handle. The eccentric locking handle tightens or loosens the bolt, so that the collar can clamp or loosen the handlebar flat tube. This structure can adjust the angle of the handlebar to the horizontal plane, but can not adjust the front and rear position of the handlebar, and it is easy to cause the handlebar to flatten or The bundle ring is worn, and the long-term use may cause the clamp to be tight. Chinese Patent No. 200910039137.7 discloses a handlebar position adjustment mechanism including the upper cover, the lower cover and the handlebar riser of the handlebar, and the side of the upper cover and the lower cover. By the locking device locking, the clamping sections of the upper and lower covers and the handlebar riser are provided with anti-slip structures, such as embossed teeth, which solves the adjustment The vertical height, front and rear positions, handlebar angle with the horizontal plane of the problem, but easy to wear, when the wear parts in contact with rain, easy to rust corrosion, replacement handlebar seem cumbersome, inconvenient. The aforementioned handlebars also have problems with grip discomfort, especially when the bicycle is traveling on uneven road surfaces, and strong bumps may cause numbness in the arms.

The present invention will be further described below in conjunction with the accompanying drawings.

The handlebar clamping device comprises a front extension 1, a clamping member 2, a fixing pin 3 and a lever 8, as shown in Fig. 1, the fixing pin 3 is placed in the clamping member 2, the fixing pin 3 and the clamping member 2 An elastic rubber pad 6 is disposed between the clamping member 2 and an upper cover 21 and a lower cover 22. The upper and lower covers are hinged on one side, and the clamping member 2 is fixed to the vertical pipe 4 by screws 5 and fixed. The pin 3 is locked, and the rear end of the front extension 1 is provided with two locking portions 11 respectively. The two locking portions 11 are respectively disposed on two sides of the clamping member 2, and the two ends of the elastic rubber pad 6 on the surface of the fixing pin 3 are respectively By the bolt locking, the front end of the front extension 1 locks the lever 8 by bolts.

The clamping member 2 can also be fixed on the vertical pipe by the eccentric locking device of the patent 201010160174.6, and the eccentric locking device is locked, so that the position of the handlebar can be adjusted more conveniently and quickly.

Similarly, the front end of the front extension 1 and the locking portion 11 can also be locked with an eccentric locking device for quick disassembly. In order to make the handlebar clamping device more beautiful, or to loosen the fixing pin 3, the elastic rubber pad 6 is prevented from slipping out, and a detachable end cover 7 is provided at both ends of the fixing pin 6, and the diameter of the large end of the end cap 7 is smaller than that of the fixing pin 3. The outer diameter is large, and the elastic rubber pad 6 is at Between the end caps 7 at both ends of the fixing pin 6.

The elastic rubber pad 6 is formed in a hollow cylindrical shape. As shown in FIG. 4, the structure is integral and the installation is convenient. It can also be set as a hollow cylinder surrounded by the film 9. As shown in Fig. 5, it is surrounded by a plurality of films 9 into a hollow cylindrical shape. When mounted on the handlebar holding device, the film 9 is pasted one by one. On the inner surface of the clamping member 2, the film 9 is enclosed into a hollow cylindrical structure, and then the fixing pin 3 is inserted into the fixing pin 3, and then the clamping member 2 is locked. In this manner, the position of the film 9 is substantially fixed, which does not cause The case where the film 9 is displaced during the installation process. Alternatively, the film 9 may be placed around the outer surface of the fixing pin 3, grasped by hand, and then locked into the holding member 2 to be locked. The material of the elastic rubber pad 6 is preferably a wear-resistant plastic material, such as rubber, silica gel, Teflon material, etc. These materials have the advantages of shock absorption, durability, replacement, and low cost, especially when driving on a bicycle. On the uneven road surface, the elastic properties of these materials have a good shock absorbing effect, which can avoid or reduce the discomfort and fatigue of the arm.

In order to better fix the protruding member 1, the clamping member 2 and the fixing pin 3, a concave-convex structure may be provided on the inner surface or the outer surface of the elastic rubber pad 6, and the outer surface of the fixing pin 3 and the inner surface of the clamping member 2 may be fixed. The shape of the inner surface of the locking portion 1 corresponds to the shape of the inner and outer surfaces of the elastic rubber pad 6. Of course, the inner and outer surfaces of the elastic rubber pad 6 may not have a concave-convex structure.

The most preferred manner is that the inner and outer surfaces of the elastic rubber pad 6 are provided with a concave-convex structure, the outer surface of the fixing pin 3 engaged with the inner and outer surfaces of the elastic rubber pad 6, the inner surface of the clamping member 2, and the front extension 1 are locked. The shape of the inner surface of the joint portion is matched with the corresponding portion of the elastic rubber pad 6, as shown in FIG. 2-5, the concave-convex structure is a groove or a tenon disposed parallel to the axial direction, and the cross-section may be corrugated or serrated. , rectangular or other irregular concave and convex shape, preferably rectangular tooth shape, the fixing pin 3, the clamping member 2, the protruding member 1 and the elastic rubber pad 6 are more closely matched, and the friction between each other is larger, and the locking is more Firm.

Another embodiment of the handlebar gripping device, as shown in FIG. 6, the inner surface of the gripping member 2 and the inner surface of the latching portion 11 of the front extension member 1 are respectively convexly fitted with the outer surface of the fixing pin 3, and are clamped. The hollow cylindrical elastic rubber pad 6 is sandwiched between the front protruding member 1 and the fixing pin 3. The inner and outer surfaces of the hollow cylindrical elastic rubber pad 6 are smooth surfaces, and the elastic rubber pad 6 has a deforming function. Therefore, although the elastic member 6 is provided in the clamping member 2, the protruding member 1 and the fixing pin 3, the inner surface of the clamping member 2 and the inner surface of the locking portion 11 of the protruding member 1 are both fixed to the fixing pin 3. The outer surface is unevenly fitted, but the elastic rubber pad 6 is not excessively thick, preferably 1 mm to 5 mm, and other structural features are the same as those of the foregoing embodiment.
