Description

Chain drive steering structure

The present invention relates to a chain steering structure, and more particularly to a structure capable of providing a chain carrying different sizes and performing a chaining operation.

Cycling is a popular leisure activity in recent years. It has the characteristics of environmental protection, sports and entertainment. It has also been promoted as a short-distance means in many developing countries to cope with the fate of the Earth's energy.

However, in bicycle riding, it is inevitable that a malfunction occurs, especially in long-distance riding, it is best to have maintenance tools to prevent accidental needs, then you can immediately carry out general maintenance and adjustment, in order to continue, no Enjoy outdoor activities intermittently.

In the faulty situation, the more difficult condition may be to replace the chain. At present, most of the conventional chain drivers have a chain body, the chain body has a groove, and one chain is provided on one side of the chain body. a shaft extending outwardly and coupled with a handlebar, wherein the chain is placed in the groove of the chain body through the structure, and the handlebar is operated to make the shaft penetrate the chain and link the chain The pin pushes out the chain and completes the chain work.

However, the above structure actually has the following disadvantages: the chain on the market is roughly divided into two types, one is a quarter chain, the connecting pin has a diameter of 2 mm, and the other is applied to a 9-11 speed chain, and the link is The pin diameter is 3 mm. However, many users will change the chain according to the occasion of riding a bicycle. For example, climbing a mountain road may require a 9-11 speed chain when riding a flat road. A quarter chain may be used in the segment. However, because the diameters of the two chains are different, the user needs to prepare two different types of chainers for chaining and chain loading, and carrying these chainers with some Tools such as pumping and digging a tire rod are bound to cause inconvenience to the user.

The object of the present invention is to solve the problem that the conventional structure needs to prepare a plurality of de-chainers, and the chain body of the present invention is provided with a steering portion, and the direction of the steering portion can be adjusted according to requirements to carry different types of chains. Perform a chaining operation.

The structure that can achieve the above object mainly comprises: a chainer body defining a plane end and a protruding end, the plane end being provided with an axial through hole and a depth mounting hole, and the protrusion The end is provided with a radial connecting hole; a latching assembly having a spring and a steel ball, which is installed in the mounting hole; and an operating wrench mounted on the connecting hole of the chain driver body, and The operating handle is provided with a chain lever; a hand piece is assembled to the through hole of the chain driver body, the hand piece extends from the bottom to the upper side, the shaft ring is provided with a ring groove, and the shaft core is drilled on the axial side a screw hole; a disassembling head mounted on the screw hole of the shaft; and a steering portion disposed in the groove of the shaft center, the steering portion having two adjacent and vertically connecting mounting plates Secondly, a steel bead having a hole for providing the cassette assembly is respectively disposed under the receiving plate, and the receiving plate, the flat end and the protruding end form a groove; and the groove is adjustable through the rotating portion; The width of the groove, and the steering portion is subjected to the click assembly The top is locked, so that the chain body carries the chains of different widths for the chain operation.

Through the above structure, the functions that can be obtained by the present invention are briefly described as follows: 1. The mounting plate can define a first receiving plate and a second receiving plate, the first receiving plate and the flat end and the protruding end The formed groove can accommodate the 9-11 speed chain; the second receiving plate can be accommodated with the groove formed by the flat end and the protruding end. The chain can therefore quickly adjust the steering portion so that the chain body carries the chains of different widths for the chaining operation.

In order to enable the reviewing committee to have a better understanding and recognition of the features and features of the present invention, the following preferred embodiments are illustrated with the following description: Referring to Figures 1 to 6, the steering structure of the present invention is The utility model mainly comprises: a chain body 10 defining a flat end 11 and a protruding end 12, the flat end 11 being provided with an axial through hole 111 and a mounting hole 112 having a depth, and the protruding end 12 Set A radial connecting hole; a latch assembly 20 having a spring 21 and a steel ball 22 mounted in the mounting hole 112; a hand piece 30 assembled to the through hole of the chain driver body 10 111. The hand piece 30 extends from the bottom to the top of the shaft 31. The shaft center 31 is provided with a ring groove 311, and a screw hole 312 is drilled in the shaft core 31. A disassembling head 40 is mounted on the shaft center. a screw hole 312; and a steering portion 50, which is sleeved in the groove 53 of the shaft core 31. The steering portion 50 has two adjacent and vertically connected receiving plates 51, and two under the receiving plate 51. A steel ball 22 for providing the cassette assembly 20 is respectively abutted, and the receiving plate 51, the flat end 11 and the protruding end 12 form a groove 53; an operating wrench 60 is mounted on the hole A connecting hole of the chain body 10, and the operating wrench 60 is provided with a chain lever;

Through the above structure, the mode of use of the present invention and the efficacies and advantages that can be obtained are briefly described as follows:

(1) Please refer to the first to sixth figures. When the user wants to disassemble the chain of different sizes, the width of the groove 53 can be adjusted through the rotating portion, and the turning portion 50 is locked by the latching assembly 20 to make the chain. The body 10 carries chains of different widths for chaining operations.

(2) Please refer to the first to second figures, wherein the receiving plate 51 defines a first receiving plate 511 and a second receiving plate 512, wherein the first receiving plate 511 and the flat end 11 The groove 53 formed by the protruding end 12 can accommodate the 9-11 speed chain, and the second receiving plate 512 can be accommodated with the groove 53 formed by the flat end 11 and the protruding end 12. Chain.

(3) Please refer to the third to sixth figures for the state of use of the present invention, which is mainly rotated from the second receiving plate 512 to the first receiving plate 511, and the rotating portion is first rotated so that the first receiving plate 511 faces the first The direction of rotation of the two receiving plates 512, because the rotating portion is pivoted on the axis 31 of the hand piece 30, has the effect of limiting the direction of rotation; and then passes under the first receiving plate 511 and the second receiving plate 512 The effect of the hole 52 and the steel ball 22 of the cassette assembly 20 is such that the steering portion 50 produces a locking effect, so that the steering portion 50 does not rotate, so the chain body 10 carries chains of different widths. By rotating the operating wrench 60, the chain lever withdraws the link pin of the chain from the completion of the chaining operation.

(4) Please refer to the second figure. In order to ensure that the receiving plate 51 can be securely fastened to the shaft core 31, the groove 311 can be fastened with a fastening member 54 so that the receiving plate 51 can be surely supported by the shaft center 31. The rotation does not leave.

In summary, the chain body 10 of the present invention is provided with a steering portion 50, which can carry different types of chains for chain operation according to the direction of the steering portion 50; and the structure of the chain has not been seen in books or Open use, in line with the requirements of the invention patent application, please ask the Bureau to understand the patent, as soon as possible to grant patents, to pray.
