Technical Field

[0001] The utility model relates to the field of protection chains, in particular to a crawler type protection chain with a tensioning and adjusting device. Background Art

[0002] When adjusting the tension of the protection chain in the prior art, it is generally necessary to use external tools to adjust the tension of the protection chain. When adjusting the protection chain with the help of external tools, the operator often needs to spend a lot of effort, and it takes a long time to adjust the protection chain, which reduces the practicality of the protection chain. Summary of the invention

[0003] Based on the above technical problems, the utility model provides a crawler protection chain with a tensioning adjustment device, including a connecting block, a plurality of semicircular teeth, a plurality of sliding structures, a plurality of connecting rods and a plurality of chains, the plurality of semicircular teeth are all arranged above the inside of the connecting block, the plurality of sliding structures are respectively connected to the corresponding plurality of connecting rods, the plurality of connecting rods are respectively connected to the corresponding plurality of chains, and the sliding structure includes a cap and a limit rod that are connected to each other.

[0004] The upper part of the interior of the connection block comprises a plurality of grooves, each groove is provided with a spring, and each spring is respectively connected with a semicircular tooth.

[0005] The number of the grooves, the number of the springs and the number of the semicircular teeth are all the same.

[0006] The cap is circular.

[0007] The diameter of the cap is greater than the length of the interior of the connection block.

[0008] The beneficial effects of the utility model are:

[0009] When the utility model is in use, if the chain needs to be adjusted tighter, the operator pushes the cover cap 3 of the sliding structure inward to shorten the distance between the two cover caps 3, thereby driving the connecting rod 4 connected to the limiting rod 6 of the sliding device to move toward the connecting block 1, so that the distance between the chains 5 at both ends of the connecting block 1 is shortened, and the semicircular teeth 2 will fix the sliding structure at the position pushed by the operator to prevent the sliding structure from rebounding, so that the chain 5 will be adjusted tighter.

[0010] If the chain needs to be adjusted to be looser, the operator can remove the cover cap 3 of the sliding module by rotating it, disconnect the connection between the limit rod 6 of the sliding structure and the connecting rod 4, adjust the distance between the limit rods 6 to a larger value, and then reconnect the limit rod 6 to the connecting rod 4, so that the distance between the chains 5 at both ends of the connecting block 1 is increased, and the semicircular teeth 2 will fix the sliding structure at the position moved by the operator to prevent the sliding structure from rebounding, so that the chain 5 will be adjusted to be looser.

[0015] The utility model provides a crawler type protection chain with a tensioning adjustment device, comprising a connecting block 1, a plurality of semicircular teeth 2, a plurality of sliding structures, a plurality of connecting rods 4 and a plurality of chains 5, wherein the plurality of semicircular teeth 2 are arranged above the inside of the connecting block 1, the plurality of sliding structures are respectively connected to the corresponding plurality of connecting rods 4, the plurality of connecting rods 4 are respectively connected to the corresponding plurality of chains 5, and the sliding structure comprises a cap 3 and a limit rod 6 which are connected to each other.

[0016] The upper part of the connection block includes a plurality of grooves 7 , each groove 7 is provided with a spring 8 , and each spring 8 is connected to the semicircular tooth 2 respectively.

[0017] The number of the grooves 7 , the number of the springs 8 and the number of the semicircular teeth 2 are all the same.

[0018] The cover cap 3 is circular.

[0019] The diameter of the cap 3 is greater than the inner length of the connecting block 1 .

[0020] The limiting rod 6 is inside the connecting block 1 , and the cover cap 3 is on the surface of the connecting block 1 and is not connected to the connecting block 1 . Example

[0021] When the utility model is in use, if the chain needs to be adjusted tighter, the operator pushes the cover cap 3 of the sliding structure inward to shorten the distance between the two cover caps 3, thereby driving the connecting rod 4 connected to the limiting rod 6 of the sliding device to move toward the connecting block 1, so that the distance between the chains 5 at both ends of the connecting block 1 is shortened, and the semicircular teeth 2 will fix the sliding structure at the position pushed by the operator to prevent the sliding structure from rebounding, so that the chain 5 will be adjusted tighter.

[0022] If the chain needs to be adjusted to be looser, the operator can remove the cover cap 3 of the sliding module by rotating it, disconnect the connection between the limit rod 6 of the sliding structure and the connecting rod 4, adjust the distance between the limit rods 6 to a larger value, and then reconnect the limit rod 6 to the connecting rod 4, so that the distance between the chains 5 at both ends of the connecting block 1 is increased, and the semicircular teeth 2 will fix the sliding structure at the position moved by the operator to prevent the sliding structure from rebounding, so that the chain 5 will be adjusted to be looser.

[0023] As described above, the distance between the chains 5 can be quickly adjusted without using external tools, which makes the operation more convenient and improves time efficiency.

[0024] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The various components mentioned in the utility model are common technologies in the existing field.
