Abstract

The utility model provides a roller chain clamping structure. The known roller chain clamping structure must be equipped with various clamping blocks, and has high cost and complex operations. The utility model provides the novel roller chain clamping structure that can clamp a plurality of specifications of chains, which is characterized in that a straining seat is provided with an empty cavity, the opening part of the empty cavity is smaller than the inside of the empty cavity, and is provided with a hole in which a compression bar with a spring is arranged, and a compaction bar is additionally arranged therein. A roller chain is put into the empty cavity, the compaction bar presses on one side of the roller chain under the action of the spring and the compression bar to press the other side of the roller chain on the wall of the empty cavity, after a force is applied on the straining seat, the compaction bar and the roller chain can not be pulled out of the opening together because the opening part of the empty cavity is smaller than the inside of the empty cavity, and the roller chain is then straightened and can bear load. Because when the compaction bar is matched with the roller chain, the diameter thereof is irrelevant to the diameter and pitch of the roller chain, the clamping structure can clamp a plurality of specifications of roller chains, is multi-purpose, and saves costs and labor.

Description

The roller chain clamp structure

Affiliated technical field

The utility model is about a kind of roller chain clamp structure.

Background technology

Known roller chain clamp structure as shown in Figure 1-Figure 3, it is made up of grip block 2 and tension seat 1, roller chain 3 places in the grip block 2.Application of force P on tension seat 1, roller chain 3 just is straightened, but and bearing load.Because the roller chain specification is various, grip block pitch H, diameter D are necessary identical with pitch h, the diameter d of roller chain, and both sides just can cooperate.So must be equipped with same various grip block, cost is higher, and operates loaded down with trivial details.

Summary of the invention

In order to overcome the deficiencies in the prior art, the purpose of this utility model provides a kind of novel roller chain clamp structure of energy clamping plurality of specifications.

The utility model is achieved in that it comprises the tension seat, it is characterized in that described tension seat is provided with a cavity, and the opening part of cavity is littler than cavity inside, and is provided with a hole, and hole mid-has the depression bar of spring, and other sets up a compressor arm.During operation, roller chain is put into cavity, compressor arm is pressed in a side of roller chain under the effect of spring and depression bar, the opposite side of roller chain is pressed on the wall of cavity.After the application of force on the tension seat, because the opening part of cavity is littler than cavity inside, compressor arm and roller chain can't be pulled out opening part together.Like this, roller chain just is straightened, but and bearing load.

The beneficial effects of the utility model are: because compressor arm is when cooperating with roller chain, the diameter of its diameter and roller chain and pitch have nothing to do, roller chain that can the clamping plurality of specifications, one-object-many-purposes, saved expense with manually.

The specific embodiment

(seeing Fig. 4 and Fig. 5) tension seat 4 is provided with a cavity 42, and its opening part 43 is littler than cavity inside.And be provided with a hole 41, and hole 41 mid-has the depression bar 6 of spring 5, and other sets up a compressor arm 7.During operation, roller chain 3 is put into cavity 42, compressor arm 7 is pressed in a side a point of roller chain 3 under the effect of spring 5 and depression bar 6, the b of the opposite side of roller chain, c point is pressed on the inwall of cavity 42, behind application of force P on the tension seat, because the opening part 43 of cavity is littler than cavity inside, compressor arm 7 and roller chain 3 can't be pulled out opening part together, like this, roller chain just is straightened, but and bearing load.

Because compressor arm is when cooperating with roller chain, the diameter of its diameter and roller chain and pitch have nothing to do (seeing Fig. 6 and Fig. 7), roller chain that can the clamping plurality of specifications, one-object-many-purposes, saved expense with manually.

Claims

1, a kind of roller chain clamp structure, it comprises the tension seat, it is characterized in that described tension seat is provided with a cavity, and the opening part of cavity is littler than cavity inside, and is provided with a hole, and hole mid-has the depression bar of spring, and other sets up a compressor arm.
