The utility model adopts the following technical scheme:

an auxiliary tool for quickly connecting a transmission roller chain comprises an adjusting rod and a hook claw, wherein the adjusting rod is connected with the hook claw through a guide sleeve arranged on the adjusting rod, and an adjusting nut matched with the adjusting rod is arranged on the outer side of the guide sleeve. Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses a collude the claw and match according to the model and the size of the roller chain of job site, make the installation of transmission roller chain simple and convenient more, reduced the work degree of difficulty, shortened operating time, improved work efficiency.

Further, the utility model discloses a preferred scheme is:

the maximum distance H from the vertical plane where the hook claw handle is located to the hook claw is smaller than the roller diameter of the roller chain; the maximum width M of the end surface of the hook solid body where the maximum distance H is located is smaller than the distance between two adjacent rollers of the roller chain.

The adjusting rod is provided with a left guide sleeve and a right guide sleeve respectively, the outer sides of the left guide sleeve and the right guide sleeve are provided with a left adjusting nut and a right adjusting nut respectively, and the left guide sleeve and the right guide sleeve are correspondingly fixed with a left hook claw and a right hook claw respectively.

The adjusting rod is a screw lever.

The two end surfaces of the hook claw handle part are respectively flush with the two end surfaces of the sleeve.

The adjusting rod is in clearance fit with the guide sleeve.

in the figure: an adjusting rod 1; a left adjusting nut 2; a left guide sleeve 3; a left hook claw 4; a right guide sleeve 5; a right adjusting nut 6; a right claw 7; a roller chain 8; a roller 801; a chain plate 802; the roller chain is articulated 9.

Detailed Description

The invention is further described below with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1: the utility model provides an appurtenance of high-speed joint transmission roller chain, by adjusting pole 1 and collude the claw and constitute, adjust pole 1 and be the screw that excels in of detaining entirely, the both ends of adjusting pole 1 are provided with left guide sleeve pipe 3 and right guide sleeve pipe 5 respectively, two guide sheathed tube inner walls are smooth, every guide sleeve pipe respectively with adjust pole 1 clearance fit, the left side of left guide sleeve pipe 3 is provided with left adjusting nut 2, the right side of right guide sleeve pipe 5 is provided with right adjusting nut 6, through adjusting left adjusting nut 2 and right adjusting nut 6, control left guide sleeve pipe 3 and the sliding displacement of right guide sleeve pipe 5 on adjusting pole 1 respectively.

In order to ensure that the hook claws can hook the rollers 801 of the roller chain 8 and cannot be clamped, the maximum distance H (namely, the section bc in the figure 1) from a vertical plane where each hook claw handle is located to the hook claw where each hook claw handle is located to the roller 801 of the roller chain 8 is smaller than the diameter of the roller 801 of the roller chain 8, the maximum width M (namely, the section ab in the figure 1) of the solid end face of the hook claw where the maximum distance H is located is smaller than the distance between two adjacent rollers 801 of the roller chain 8, and the maximum thickness of each hook claw is smaller than the shortest distance L (namely, the section ef in the figure 4) between two chain plates corresponding to the same section of the same roller chain 8.

The utility model discloses when using, through adjusting left adjusting nut 2 and right adjusting nut 6, adjust left side guide sleeve pipe 3 and right side guide sleeve pipe 5 to suitable position respectively, then collude claw 4 and the right side respectively and insert on the roller in the outside of two sections roller chains 8 with claw 7, then respectively left side adjusting nut 2 and right adjusting nut 6, make two adjusting nut move in opposite directions, left side adjusting nut 2 makes left side guide sleeve pipe 3 move right promptly, right side adjusting nut 6 makes right side guide sleeve pipe 5 move left, left side collude claw 4 and right side simultaneously and collude claw 7 and move along with the guide sleeve pipe at place separately respectively, make the interval between the tip of two sections roller chains 8 shorten to suitable position, correspond respectively the both ends of roller loose joint 9 with the end connection of two sections roller chains 8, constitute a complete roller chain. After the installation is finished, the left adjusting nut 2 and the right adjusting nut 6 are respectively adjusted, the two adjusting nuts move in opposite directions, and the left hook claw 4 and the right hook claw 7 are manually adjusted to appropriate positions, so that the device can be taken out from the roller chain.

The claw in this embodiment can make several specifications according to the specification model of the transmission roller chain on the operation site, and the roller chain that works as required selects correspondingly, and the connection of the roller chain is accomplished fast under the prerequisite of guaranteeing the installation quality.

The above is only the concrete implementation manner of the present invention, but the protection of the present invention is not limited thereto, and all the equivalent changes or replacements proposed to the technical features of the present technical solution, which can be considered by those skilled in the art, are covered within the protection scope of the present invention.
