Problems solved by technology

[0004] In addition, in public places such as hospitals, the chain device cannot be exposed. If it is overhauled and maintained, the entire guard plate must be opened, and the maintenance labor cost is high. However, if the maintenance frequency is reduced, there will be medical hidden dangers and medical accidents.

Embodiment 1

[0017] Embodiment 1 can be used in situations where the chains of bicycles and motorcycles are exposed. Such as Figures 1 to 5 As shown, Embodiment 1 of the present invention includes a casing 10 with an upper opening, and a vertical sprocket 11 in the middle, and the present invention has a symmetrical structure on the plane where the sprocket 11 is located. A horizontal shaft 9 is fixedly connected to the center of the sprocket 11 , and both ends of the horizontal shaft 9 are connected to the housing 10 in rotation. Both sides of the sprocket 11 are respectively provided with a horizontal bevel gear 12 fixed on the horizontal shaft 9 , and each of the horizontal bevel gears 12 meshes with a vertical bevel gear 13 . The upper part of the vertical bevel gear 13 is fixedly connected to a hollow shaft 8, at least the upper half of the hollow shaft 8 is a hollow structure, and the outer surface of the hollow shaft 8 is nested with one or more sleeve 17 structures, so The struc...

Embodiment 2

[0022] In embodiment 2, the technical features not mentioned in this embodiment are all the same as in embodiment 1. Such as Figure 6 As shown, the hole in the housing 10 at the push rod 6 is a light hole, the push rod 6 is located in the hole, a platform 22 is fixedly connected to the housing 10, and the handle 5 is connected to the platform 22 A torsion spring (not shown in the figure) is provided at the hinge, and the handle 5 is placed in a direction parallel to the push rod 6 through the elastic action of the torsion spring. The push rod 6 and the handle 5 are connected by a connecting rod 21, and the two ends of the connecting rod 21 are respectively hinged with the push rod 6 and the handle 5, wherein the hinge point between the connecting rod 21 and the handle 5 is connected with the handle 5 and the platform. The line connecting the hinge points between 22 is perpendicular to the axis of the handle.

[0023] When the pin 19 deviated, the handle 5 was rotated to pus...

Abstract

The invention discloses a chain inspecting and repairing tool, and belongs to the field of hardware tools. The chain inspecting and repairing tool is characterized in that the tool comprises a shell with an opening in the upper portion of the shell, and a vertical chain wheel is arranged in the middle of the tool; a horizontal shaft is fixedly connected with the center of the chain wheel; a horizontal bevel gear is arranged on each of two sides of the chain wheel; a hollow shaft is fixedly connected with the upper portion of each vertical bevel gear; an inspecting member is arranged in a cavity of the hollow shaft; a flexible shaft penetrates through the inside of a cavity in the middle of a vertical column of the inspecting member; a hollow screw is arranged on the shell, a push rod is arranged in a stepped hole of the hollow screw, and a handle is hinged to the outer end of the hollow screw. Compared with the prior art, the chain inspecting and repairing tool is characterized by being capable of efficiently and quickly inspecting and repairing chains.

Description

technical field [0001] The invention relates to a tool, in particular to a chain overhauling tool suitable for overhauling bicycles. Background technique [0002] Chain is an important power transmission part of mechanical equipment, widely used in various fields. After using for a period of time, the phenomenon that chain disconnection sometimes occurs, such as bicycles, motorcycles and the like, once disconnected when driving halfway, often cannot be connected by hand, which brings great inconvenience to users. [0003] The chain connects several chain pieces together through pins, each of the two ends of the pin protrudes from the outer chain piece, and the pin is pushed to one side under the action of external force, which will cause the chain to break . If the length of the pin protruding from the chain piece can be checked in time before use, if the pin is biased to one side, correct it in time, and the chain disconnection can be well avoided. [0004] In addition, ...
