Problems solved by technology

[0008] However, the work of assembling each of the locking devices is quite cumbersome, and in addition to more assembly processes, the manufacturing precision and cost requirements are also relatively high, and the locking devices have many components, and the It is difficult to adjust the tight operation, so it has a considerable weight, which does not meet the market demand for lightweight bicycles

Embodiment Construction

[0025] First please refer to Figure 1 to Figure 5 , the structure of a head cup upper cover 10 with tight adjustment provided by the present invention is arranged between a head cup set 20 and a handle riser 30, and a front fork pipe 40 is coaxially arranged in series Each of the upper cover 10, the headset 20, and the inner diameter edge of the handle standpipe 30; wherein the upper cover 10 includes: a base 11, and a first screw 12 disposed in the base 11 And a second rotary member 13.

[0026] The headset 20 has an abutting block 21 and a bearing element 22 , the abutting block 21 is disposed above the bearing element 22 and partially abuts against it.

[0027] The base body 11 is hollow cylindrical with a predetermined height, and its inner diameter edge is divided by a first threaded portion 111 and a second threaded portion 112 which are mutually oppositely helical on the same central axis 113 .

[0028] The first screw 12 is screwed on the first threaded part 111, an...

Abstract

The invention provides a headset upper cover structure having a function of forcing regulation, which is arranged between a headset set and a handle upright pipe. The structure comprises a base which is provided with reversely screwed first and second threaded parts along coaxial line along the internal edge, a first whirling element which is threaded on the first threaded part and is capable of generating radial displacement in the spiral way so as to resist one end face thereof on the handle upright pipe, and a second whirling element which is threaded on the second threaded part and is capable of generating radial displacement in the spiral way so as to resist one end face thereof on the headset. When the base is rotated, the first and second whirling elements will synchronously generate corresponding radial displacement so as to change the distance between the end faces for performing the function of forcing regulation.

Description

technical field [0001] The present invention relates to an upper cover structure, in particular to a head cup upper cover structure with tight adjustment, which is used on the top of the head headset of a bicycle as an upper cover for the abutment function, so that the head headset and the front fork tube It can be used for relative rotation and at the same time has the function of tight adjustment. Background technique [0002] The headset structure is mainly installed between the head tube and the front fork to provide smooth rotation and make the steering and turning operations of the bicycle smoother; generally, the headset is equipped with balls, rollers or bearings. Install the head cup assembly between the head tube and the front fork, and then set a locking structure on the top of the front fork and the head tube to tighten the relative components in each of the head tube and the head tube, so as to provide the head tube and the front There is relative rotational mo...
