[0003] Therefore, a kite reel brake device solving the above problems is needed. SUMMARY

[0004] The utility model provides a kite reel brake device, through the cooperation of friction stroke adjustment groove and ball, the axial stroke of brake cover is increased, thereby the axial clamping force of friction assembly is increased, the friction of braking friction assembly is increased, and then the braking force of kite reel brake device is improved, so that the device can better adapt to high-frequency brake environment.

[0005] The technical scheme of the utility model is as follows:

[0006] The kite reel brake device comprises a main shaft for installing a winding reel, and further comprises:

[0007] The brake driving assembly comprises a support mounting seat, a pushing sleeve is rotatably installed on the support mounting seat, a brake cover is slidably installed on the support mounting seat, the brake cover is rotatably installed on the main shaft, a plurality of annularly arranged friction stroke adjustment grooves are arranged on the adjacent two end faces of the pushing sleeve and the brake cover, a ball is arranged in every two opposite friction stroke adjustment grooves, and a brake handle is clamped on the pushing sleeve.

[0008] The friction assembly is slidably installed on the main shaft and is arranged between the winding reel and the brake driving assembly.

[0009] As a preferred technical scheme, the groove depth and the groove width of each friction stroke adjustment groove on the pushing sleeve gradually increase in the clockwise direction, and the groove depth and the groove width of each friction stroke adjustment groove on the brake sleeve gradually increase in the counterclockwise direction.

[0010] As a preferred technical scheme, the brake cylinder is rotatably installed on the main shaft, the friction assembly comprises a clamping piece clamped in the brake cylinder, the brake cylinder is provided with a first compression friction plate and a second compression friction plate, the clamping piece is arranged between the first compression friction plate and the second compression friction plate, the brake cylinder and the clamping piece are sleeved on the main shaft, the first compression friction plate and the second compression friction plate are clamped on the main shaft, and reset elements are arranged between the brake cylinder and the first compression friction plate and between the first compression friction plate and the second compression friction plate.

[0011] As a preferred technical scheme, the first compression friction plate comprises a first compression piece, and a friction plate is arranged on each side of the first compression piece, the first compression friction plate comprises a second compression piece, and a friction plate is arranged on a side of the second compression piece opposite to the clamping piece.

[0012] As a preferred technical scheme, a rotating bearing is arranged between the main shaft and the brake sleeve.

[0013] With the above technical scheme, the kite wheel brake device has the following beneficial effects:

[0014] Since the kite wheel brake device comprises a brake driving assembly and a friction assembly, in the process of using the device, the main shaft is rotatably installed on the kite wheel support, the support mounting seat is connected with the kite wheel support, the winding wheel is connected with the brake sleeve, when it is necessary to brake and slow down the winding wheel, the brake handle is rotated, the pushing sleeve is rotated, the steel ball moves from one end to the other end in the corresponding friction stroke adjustment groove, the steel ball pushes the brake sleeve to move away from the winding disc along the main shaft, the brake sleeve drives the main shaft to move, the main shaft drives the friction assembly, and the friction assembly combines the winding disc and the main shaft, so that the winding disc is slowed down.

[0015] The arrangement of the steel ball also reduces the friction force between the brake sleeve and the pushing sleeve, and makes the braking of the winding disc more smooth and labor-saving.

[0016] Since the groove depth and groove width of the friction stroke adjusting groove on the pushing sleeve gradually increase in the clockwise direction, and the groove depth and groove width of the friction stroke adjusting groove on the brake sleeve gradually increase in the counterclockwise direction, when the brake handle is rotated clockwise, the friction stroke adjusting groove on the pushing sleeve pushes the ball to move from the deep groove of the friction stroke adjusting groove to the shallow groove part, so that the ball moves the brake sleeve away from the winding wheel.

[0017] Since the friction assembly includes the clamping piece, the first compression friction piece and the second compression friction piece, as the brake sleeve moves away from the winding wheel, the main shaft drives the brake cylinder to move, the clamping piece, the first compression friction piece and the second compression friction piece gradually adhere to each other, and the friction force makes the winding disc gradually slow down, so that the brake deceleration of the winding disc is realized, after the brake of the winding disc is completed, the brake handle is rotated counterclockwise, the ball moves to the shallow groove part of the friction stroke adjusting groove, and under the action of the reset element, the brake sleeve is reset, and the clamping piece, the first compression friction piece and the second compression friction piece are separated.
