Description

The outer cylinder is formed with a grip sleeve of different thickness

The invention relates to a grip sleeve, and more particularly to a grip sleeve having different thicknesses formed on the outer cylinder.

Pressing, the grip sleeve is applied to the grip of the bicycle as a buffering application, and the transverse sectional view thereof is as shown in Fig. 6, and the conventional grip sleeve is disposed in an outer cylinder of the inner cylinder 51 having a circular shape. The inner cylinder 51 and the outer cylinder 52 are both round and round, and both are concentrically sleeved on the grip (not shown), in other words, the outer cylinder 52 and the inner cylinder 51. The center point of the grip is the point P2. With the above structure, the outer sleeve 52 of the grip sleeve is formed to have a uniform thickness for the rider to hold while riding.

However, when riding a bicycle, the rider grasps the grip with his hand to control the car, and needs to sensitively sense the condition of the car body and needs flexible maneuverability; on the other hand, the vibration of the car body at the time of riding is simultaneously transmitted to the car through the grip. The rider therefore needs cushioning that absorbs the impact force. However, the above two requirements for the structural thickness of the grip sleeve are opposite. In detail, the handling requirements are thinner for thickness, while the cushioning property requires a thicker structure. Therefore, the conventional thickness of the grip sleeve cannot meet the requirements of excellent handling and cushioning at the same time, and it is therefore necessary to develop a grip sleeve having different thicknesses in different orientations of the outer cylinder to meet the above requirements.

In view of this, how to improve the above problems is the primary problem to be solved by the present invention.

The main object of the present invention is to provide a grip sleeve having different thicknesses formed by an outer cylinder, which utilizes the mutual matching of the respective structural shapes and arrangement positions of the inner cylinder and the outer cylinder, so that the outer cylinders are formed with different thicknesses in different orientations. The grip sleeve has excellent cushioning and handling.

In order to achieve the foregoing objective, the present invention provides a grip sleeve having different thicknesses formed by an outer cylinder, comprising an outer cylinder having a circular tubular shape and an inner cylinder, wherein the outer cylinder axially penetrates a first hollow portion, the inner cylinder Forming a shape corresponding to the first hollow portion and passing through the first hollow portion, and inserting a second hollow portion axially through the inner tube, so that the grip sleeve can be sleeved on the second hollow portion a gripper; wherein the relative position of the outer cylinder and the inner cylinder and the shape of the two are matched to each other to form different thicknesses at different positions of the outer cylinder; and the two ends of the inner cylinder are respectively protruded The outer cylinder is formed to form two positioning ends, and a positioning ring is respectively disposed on the two positioning ends, thereby fixing the inner cylinder and the outer cylinder to the grip.

Preferably, in the transverse section of the grip sleeve, the outer cylinder, the second hollow portion, the inner cylinder and the outer portion of the first hollow portion are all perfectly rounded, and the axis of the inner cylinder is defined as a first mandrel, the axis of the second hollow portion is a second mandrel, the axis of the outer cylinder is a third mandrel, and the axis of the first hollow portion is a fourth mandrel; The second hollow portion is disposed at an offset from the axis of the inner cylinder such that an offset distance is formed between the second mandrel and the first mandrel, and the first hollow portion is disposed offset from the outer axis of the outer cylinder Wherein, an offset distance is formed between the fourth mandrel and the third mandrel, whereby the outer cylinder is formed with a thick portion and a thin portion at different positions.

Further, the third mandrel of the outer cylinder coincides with the position of the second mandrel of the second hollow portion.

In a second preferred embodiment, in the transverse section of the grip sleeve, the outer cylinder has an elliptical outer contour, and the first hollow portion of the outer cylinder forms an ellipse corresponding to the inner cylinder for The inner cylinder is bored and defines a long shaft and a short shaft; and the outer cylinder has a right outer contour, so that the outer cylinder is formed with a thin portion corresponding to the long axis of the first hollow portion, and corresponds to A thick portion is formed at a short axis of the first hollow portion.

Further, the axial center positions of the outer cylinder, the first hollow portion, the inner cylinder and the second hollow portion coincide.
