Problems solved by technology

[0003]At present, the existing domestic chain adjuster production process is traditional, the product shape is old and bulky, the tensile strength is small, the safety factor is low, and it is inconvenient to use
At the same time, the existing chain adjusters often only clamp the chains inside the adjuster for fixing, which is less safe. In the process of use, it is easy to cause the chain to fall off from the inside of the adjuster slot and cause accidents, which has a high security risks

Embodiment 1

[0036] According to an embodiment of the present invention,

[0037] see Figure 1-10 , a croissant chain adjuster, comprising an adjuster body 1, the outer walls of both sides of the adjuster body 1 are provided with fixing holes 2, and the circumferential inner wall of the fixing hole 2 is fixedly connected with a fixing ring 5, the adjuster One side of the outer wall of the body 1 is fixedly connected with a clamping arm 4, and the number of the clamping arms 4 is two groups. The cross-section is chain-shaped, and the inside of the card slot 3 is clamped with a chain body 7. The side of the regulator body 1 is a streamlined structure, and the inside of the card slot 3 is provided with a protection component. Since the regulator body 1 The cross-section of the regulator body 1 is H-shaped, and the side of the regulator body 1 is designed as a streamlined structure, so the overall performance of the regulator body 1 can be enhanced, and its tensile strength is also increased...

Embodiment 2

[0039] see Figure 4-7 , the protection assembly includes a slot 18 opened on one side of the clamping arm 4, the inside of the slot 18 is plugged with a pull column 13, the inside of the slot 18 is provided with an elastic assembly, the The outer circumferential wall of the pull column 13 is provided with a first groove 8, the specification of the first groove 8 is the same as the outer width specification of the chain body 7, and the inner walls of both sides of the first groove 8 are provided with Clamping groove 17, the outer circumferential wall of the chain body 7 is wrapped in the inside of the clamping groove 17, and one side of the clamping arm 4 is provided with a guide assembly for limiting the position of the pulling column 13, The chain body 7 can be effectively fixed by the protection assembly, which prevents the chain body 7 from falling off during the process of being snapped into the card slot 3. The outer circumferential wall of the body 7 is wrapped inside,...

Embodiment 3

[0041] see Figure 4 , 6 , the guide assembly includes a first rectangular slot 9 opened on the outer wall of one side of the clamping arm 4, the four inner walls of the first rectangular slot 9 are fixedly connected with a connecting rod 10, and one end of the outer wall of the connecting rod 10 A guide ring 12 is fixedly connected, and a connecting column 11 is inserted into the inside of the guiding ring 12. One end of the connecting column 11 forms a fixed connection with the drawing column 13, and the drawing column 13 is far away from the connecting column. One end of 11 is provided with a pressing assembly, and the provided guide assembly can ensure that the pulling action of the pulling column 13 can run stably.

Abstract

The invention discloses a claw chain regulator. The claw chain regulator comprises a regulator body, fixing holes are formed in the outer walls of the two sides of the regulator body, fixing rings are fixedly connected to the inner walls of the circumferences of the fixing holes, two sets of clamping arms are fixedly connected to the outer wall of one side of the regulator body, clamping grooves are formed in the outer walls of the tops of the two sets of clamping arms, the cross section of each clamping groove is in a chain shape, a chain body is clamped in each clamping groove, the side edge of the regulator body is of a streamline structure, and a protection assembly is arranged in each clamping groove. The arranged protection assemblies can effectively fix the chain bodies, the situation that the chain bodies fall off in the process of being clamped into the clamping grooves is avoided, the clamping grooves formed in the inner walls of the two sides of first grooves wrap the circumferential outer walls of the chain bodies, and the fixing effect of the protection assemblies on the chain bodies is further guaranteed.

Description

technical field [0001] The invention relates to the field of chain adjusters, in particular to a croissant chain adjuster. Background technique [0002] Chain adjusters are mainly used for length adjustment of lifting chains or chain slings to adjust the length of the chain to make the operation more flexible. The chain adjuster is mainly forged, usually made of high-quality alloy steel. Its outstanding features are wear resistance, high temperature resistance, low ductility, and will not elongate after being stressed. It has a long service life and is suitable for large-scale , Frequently used occasions. [0003] At present, the existing domestic chain adjusters have traditional production techniques, and the products are old and bulky, with low tensile strength, low safety factor and inconvenient use. At the same time, the existing chain adjusters often only clamp the chains inside the adjuster for fixing, which is less safe. In the process of use, it is easy to cause th...
