[0002] The anti-slip hand brake is composed of a housing, a base, a hand wheel, a functional handle, a driving shaft, a chain winding shaft, a ratchet, a gear, a gear, a clutch, a chain, a locking mechanism, etc. These components together give the anti-slip hand brake a variety of functions and characteristics. Specifically, the hand brake has the functions of braking, relieving, force adjustment braking and locking anti-slip, which enable it to effectively control and manage the movement state of the machine in various working environments. In addition, the anti-slip hand brake also has the characteristics of large braking force, compact structure, and light weight, which make it highly efficient and convenient in design and use.

It is convenient to quickly install the active shaft and the key wheel, and the detachable structure is convenient for the maintenance of the active shaft and the key wheel.

[0011] According to the anti-slip hand brake anti-rust active shaft composition structure, the number of the key hole 1 and the number of the key hole 2 are both three, which is convenient for rapid positioning and installation.

[0012] According to the anti-slip hand brake anti-rust active shaft composition structure, the axis center lines of the key hole 1 and the key hole 2 coincide with each other, which facilitates the rapid positioning, installation and removal of the connecting key.

[0013] According to the anti-slip hand brake anti-rust driving shaft composition structure, a circular groove is formed in a circular array on the side wall of one end of the end shaft, so as to facilitate the tightening and confirmation of torque by special tooling and prevent the failure of the thread caused by insufficient tightening of the thread.

[0014] According to the anti-slip hand brake anti-rust driving shaft composition structure, the number of the circular grooves is four, which is convenient for the fastening installation between the end shaft and the optical axis.

The optical axis 102 in the driving shaft mechanism 1 passes through the clutch 10 and the ratchet 11 and is rotatably connected to the clutch 10 and the ratchet 11. When braking is required, the driving shaft 101 is installed with the external rotating parts through the threaded groove 8, and the driving shaft 101 is driven to rotate through the external rotating parts. The rotation of the driving shaft 101 drives the optical axis 102 and the key wheel 9 to rotate, and the key wheel 9 rotates to drive the clutch 10 to make axial movement. The clutch 10 makes axial movement to transmit the torque to the gear 2, and the gear 2 drives the external gears to mesh and rotate, thereby achieving a braking effect. At the same time, the driving shaft mechanism 1 is fastened to the end shaft 3 through the first thread 5, the second thread 6 and the thread glue 7, so that when the driving shaft mechanism 1 rotates, the driving shaft mechanism 1 can be prevented from loosening, which effectively extends the service life of the driving shaft mechanism 1 and improves the stability of the overall structure.

[0029] The outer surface of one end of the driving shaft 101 in the driving shaft mechanism 1 is provided with a key hole 12 in the form of an annular array, and the outer surface of the key wheel 9 is provided with a key hole 2 13.

At the same time, the driving shaft mechanism 1 is fastened to the end shaft 3 through the first thread 5, the second thread 6 and the thread glue 7, so that when the driving shaft mechanism 1 rotates, the driving shaft mechanism 1 can be prevented from loosening, effectively extending the service life of the driving shaft mechanism 1, and the contact area between the driving shaft mechanism 1 and the inner wall of the gear 2 is reduced through the plane 4. At the same time, the plane 4 has a certain repair effect, so that the rust between the gear 2 and the driving shaft mechanism 1 can be cleaned to avoid rust between the gear 2 and the driving shaft mechanism 1, thereby improving the stability of the overall structure.
