Aiming at the defects in the prior art, the invention aims to solve the technical problem that when the conventional quick mounting device for the engine transmission chain is ejected into a pin shaft, a chain link is easy to move, so that the ejection direction is deviated, and the chain is damaged.
In order to solve the above technical problem, the present invention provides a device for quickly mounting a transmission chain of an engine, comprising: a rotating shaft, a connecting rod, a base, a screw rod, a top rod and a clamping plate,
the handle is triangular and hollow; the front end of the upper part of the handle is provided with a base which is cylindrical, the interior of the base is provided with a threaded hole, the rear end of the connecting rod is provided with a screw rod, the screw rod is screwed into the threaded hole of the base, the connecting rod is provided with a through hole, a rotating shaft penetrates into the through hole,
the handle is characterized in that a push rod is installed at the front end of the screw rod, a support is arranged at the rear part of the upper surface of the handle, a avoiding hole coaxial with the push rod is formed in the support, a clamping plate is hinged to the support and provided with an angle and can rotate along a hinge rod, and positioning teeth are arranged on the upper surface of the handle between the support and the base and are two vertical plates with semicircular notches.
Further, the clamping plate is a loose-leaf.
Further, the length of the handle is 8-12 cm.
Furthermore, limiting pins are arranged at two ends of the rotating shaft to prevent the rotating shaft from falling off.
The invention has the beneficial effects that:
the chain link dismounting and mounting device has the advantages that the structure is simple, the chain is convenient to dismount and mount, and the chain link can be clamped by the clamping plate before the ejector rod pushes the shaft pin, so that the action stability of the ejector rod is kept, and the success rate of dismounting and mounting the chain link is improved.
Drawings
FIG. 1 is a schematic perspective view of a quick mounting device for an engine drive chain according to the present invention;
fig. 2 is a schematic cross-sectional view of the quick mounting device for the transmission chain of the engine according to the present invention.
In the figure: 1. the device comprises a rotating shaft, 2, a connecting rod, 3, a base, 4, a handle, 5, a clamping plate, 6, avoidance holes, 7, positioning teeth, 8, a push rod, 9 and a screw rod.
Detailed Description
The details of the present invention are described below with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, a quick mounting device for a transmission chain of an engine comprises: a rotating shaft 1, a connecting rod 2, a base 3, a screw 9, a mandril 8 and a splint 5,
as shown in fig. 2, the handle 4 is triangular and hollow; the front end of the upper part of the handle 4 is provided with a base 3, the base 3 is cylindrical, the interior of the base 3 is provided with a threaded hole, the rear end of the connecting rod 2 is provided with a screw 9, the screw 9 is screwed into the threaded hole of the base 3, the connecting rod 2 is provided with a through hole, the rotating shaft 1 is penetrated in the through hole,
the front end of the screw rod 9 is provided with an ejector rod 8, the rear part of the upper surface of the handle 4 is provided with a bracket, the bracket is internally provided with a avoidance hole 6 which is coaxial with the ejector rod 8, the bracket is articulated with a splint 5, the splint 5 has an angle and can rotate along an articulated rod,
the upper surface of the handle 4 between the support and the base 3 is provided with positioning teeth 7, and the positioning teeth 7 are two vertical plates with semicircular gaps.
In practical applications, the cover 5 is a hinge.
In practical application, the length of the handle 4 is 8-12 cm.
In practical application, limiting pins are arranged at two ends of the rotating shaft 1 to prevent the rotating shaft from falling off.
The working principle of the invention is as follows:
the quick installation device for the transmission chain of the engine is a tool for cutting off or connecting the chain. When the device is used for quickly mounting the transmission chain of the engine, the engine is preferably horizontally placed for convenient operation. The correct holding method of the quick installation device for the engine transmission chain is that one hand is used for transversely holding, the handle 4 is tightly clamped by fingers, the chain is clamped between the positioning teeth 7, then the clamping plate 5 is pressed tightly, the upper ejector rod 8 is aligned to the connecting pin of the chain, and the other hand is used for slowly rotating the ejector rod 8. The feel is the best of what the top will be when it is cut and installed. However, there is a principle that the shaft pin is never completely pushed away. The pin is seen on the surface to be a cylinder which is actually a point hyperbolic curve, namely, two ends are thick and the middle is thin, and if the pin is completely pushed away, no point violence means can be installed. Meanwhile, the pin preferably protrudes a little bit on the inner side of the chain, and is enough to be 0.5mm, so that the other end can be easily hung when the pin is connected, and the connection operation is convenient. It should be noted that the rotation of the connected section is usually slightly unsmooth, and the connected section needs to be pulled back and forth several times by hand.
In conclusion, the chain link clamping device has a simple structure, is convenient to disassemble and assemble a chain, and can clamp the chain link by using the clamping plate before the ejector rod pushes the shaft pin, so that the action stability of the ejector rod is kept, and the success rate of disassembling and assembling the chain link is improved.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. The directional indicators such as front, back, left, right, end, front, etc. are only used for describing the structure, but not for limitation. It should be understood by those skilled in the art that the foregoing embodiments are merely illustrative of the technical spirit and features of the present invention, and the present invention is not limited thereto but may be implemented by those skilled in the art.
