Referring to fig. 2 and 3, a second embodiment of the present application provides another tensioning adjustment mechanism for a tracked robot based on the tensioning adjustment mechanism for a tracked robot provided in the first embodiment of the present application. The second embodiment is only the preferred mode of the first embodiment, and the implementation of the second embodiment does not affect the implementation of the first embodiment alone.

Specifically, the tensioning adjustment mechanism for the crawler robot provided in the second embodiment of the present application is different in that the tensioning adjustment mechanism for the crawler robot is provided with a positioning assembly 10 on the support tube 1, the positioning assembly 10 includes a mounting plate 101, a positioning rod 102 is slidably connected to the mounting plate 101, a first spring 103 is sleeved on a surface of the positioning rod 102, and a pull disc 104 is fixedly mounted on a surface of the positioning rod 102; rotating assembly 11, rotating assembly 11 fixed mounting be in the one end of tensioning threaded rod 3, rotating assembly 11 includes rolling disc 111, rolling disc 111 rotates and is connected with fixed block 112, fixed mounting has connecting plate 113 on the fixed block 112, sliding connection has gag lever post 114 on the connecting plate 113, the one end fixedly connected with connection pad 115 of gag lever post 114 to the surface cover of gag lever post 114 is equipped with and pulls spring 116, spacing groove 117 has been seted up on rolling disc 111 to locating slot 118 has been seted up on rolling disc 111, spliced eye 119 has been seted up to the inside of fixed block 112, the inside sliding connection of spliced eye 119 has catch bar 120.

After the fixed block 112 is rotated, the push rod 120 can be pulled out from the inside of the fixed block 112, so that the space occupied by the push rod 120 is reduced.

The mounting plate 101 is fixedly mounted on the support tube 1, one ends of the positioning rod 102 and the limiting rod 114 are both arc-shaped ends, and the first spring 103 is located between the pull disc 104 and the mounting plate 101.

The first spring 103 pushes the pull disc 104, so that the pull disc 104 drives the positioning rod 102 to engage with the positioning slot 118.

The limiting groove 117 and the positioning groove 118 are both provided with a plurality of grooves, and the plurality of limiting grooves 117 and the plurality of positioning grooves 118 are uniformly distributed on the rotating disc 111.

A plurality of positioning grooves 118 may position the rotating disk 111 rotated at different angles.

One end of the positioning rod 102 is adapted to the positioning slot 118, and one end of the limiting rod 114 is adapted to the limiting slot 117.

The limiting rod 114 is clamped with the limiting groove 117, so that the limiting rod 114 can drive the rotating disc 111 to rotate synchronously when rotating.
