Description

Demolition head structure improvement

This creation is about the improvement of the disassembly head structure of a de-chaining device.

According to the conventional bicycle de-chaining device structure (refer to the fifth and sixth figures of the conventional de-chaining device and the disassembling operation diagram), a de-chaining device 70 is provided with a positioning notch 71 on one side thereof, and The opposite side of the positioning notch 71 is screwed to a circular grip handle 72, and the other end surface is screwed to a movable plug body 73. The end of the movable plug body 73 is provided with a round rod 74, and the other end surface is screwed and disassembled. The head 75; when the chain detaching action is to be performed, the circular grip handle 72 screwed by the detacher 70 is held by one hand, and the chain 76 is placed in the positioning yoke 71 of the detacher 70 and rotated. The dismounting head 75 moves it inwardly to urge the fixed chain 76, and then rotates the movable plug body 73 so that the round rod 74 is screwed inwardly against the shaft 77 of the chain 76 to disengage the shaft from the chain 76, and finally the disassembling head 75 Bend the shaft 77 to complete the detachment.

However, the conventional structure has the following disadvantages:

1. The dismantling head 75 of the conventional structure has a flat section. As shown in the sixth figure, when the shaft 77 of the bent chain 76 is pushed, an interference problem occurs with the chain 76, which causes the unlinking operation to be unsmooth.

The main purpose of this creation is to improve the problem that the above-mentioned dismantling head is not smooth. The main technique is to provide a circular arc angle at the end of the disassembling head so that the disassembling chain has a large moving angle when the chain is removed, so as to facilitate bending. The shaft of the chain works.

The structure that can achieve the above-mentioned functions mainly comprises: a de-chainer body, an operating hand and a disassembling head, the de-chaining body has a solid-chain groove and has a solid-chain plate, and the operation is performed. The snail is disposed at one side of the main body of the derailleur, and the operation handle has a movable portion, and the movable portion can be displaced in front and rear of the fixed chain slot, and the detaching head is disposed at the other end of the detacher body and the detaching The head is provided with a continuous perforation, and the front end of the disassembling head has a threaded section for screwing to the derailleur body to form a top abutting end; and the disassembling head is provided with an arc angle on one side of the threaded section to lift the disassembling head The bendable angle makes it easier to bend the chain shaft.

Therefore, with the technical means of this creation, a brief description of the efficacy of this creation can be found as follows:

1. The disassembly head of the present invention has an arc angle, so that the angle of the disassembly head bending the shaft can be improved, in other words, it is not easy to interfere with the chain, so that the bending chain shaft can be operated more smoothly.

In order to enable your review board to have a better understanding and recognition of the features and characteristics of this creation, the following preferred examples are listed below with the following description:

Please refer to the first to second figures. The structure of the disassembling head of the present de-chaining device is mainly composed of a de-chaining device body 10, an operating handle 20 and a disassembling head 30. The de-chaining body 10 has a The solid chain slot 11 has a solid chain plate 12, and the operation handle 20 is screwed to one side end of the derailleur body 10, and the operation handle 20 has a movable portion 21, and the movable portion 21 can be in the fixed chain slot. The front and rear displacements of the middle, the dismounting head 30 are disposed at the other end of the derailleur body 10, and the disassembling head 30 is provided with a consistent perforation 32. The front end of the disassembling head 30 has a threaded section for screwing to the derailleur body 10. A top abutting end 31 is formed; the dismounting head 30 is provided with an arc angle 33 on one side of the threaded section.

With the above structure, the usage of the creation and the available functions are briefly described as follows:

Please refer to the third and fourth figures to place the chain 50 on the dechainper body 10 In the solid chain groove 11, the chain 50 is supported by the fixed chain plate 12, and the detaching head 30 is rotated to displace the fixed end chain 31 toward the fixed chain plate 12, and then the handle 20 is rotated to move the movable portion 21 toward the detaching head. The abutting end 31 of the 30 moves, so that the strut 51 of the chain 50 is withdrawn, and finally the through hole 32 of the disassembling head 30 is aligned with the strut 51. Since the disassembling head 30 is provided with an arc angle 33, the disassembling head 30 can be bent. The angle makes the bending of the chain 50 shaft work more convenient.

Please continue to refer to the first and second figures. In order to make the de-linking operation smooth, the lower end of the original de-chainer body 10 is provided with a grip 40 for the user to hold, which makes the work more convenient.

Please continue to refer to the first and second figures. The movable end of the operation handle 20 is further provided with a round rod 22 for providing the push rod 51.

In order to make the disassembling head 30 of the present invention can be broken according to the strut 51 of the chain 50 of different sizes, the arc angle 33 of the disassembling head 30 can be set to be paid by the arc to the lateral abutting end 31. Expanded taper angle.

In summary, the present invention mainly provides an arc angle 33 through the section end of the disassembling head 30 so that the chain detaching head has a large movable angle during the chain detaching, so as to facilitate the bending of the chain 50; and the composition thereof The structure has not been seen in various books or publicly used, and it is in line with the requirements of the new patent application, so please ask the Bureau to give it a patent, and to pray.

The above description is only for the preferred embodiment provided by the present invention, and is not intended to limit the scope of implementation of the present invention.
