[0019] A brake pad which can be conveniently installed, as shown in Figure 1 The arc-shaped framework 1 is fixedly connected with the friction lining 3 through the telescopic connecting device 2, the friction lining 3 is fixed on the outer side end face of the arc-shaped framework 1, the telescopic connecting device 2 is connected with the lining 11 of the arc-shaped framework 1 through the horizontal screw rod 21, and the telescopic connecting device 2 is connected by being inserted into the arc-shaped grooves 31 at the front end face and the rear end face of the friction lining 3 through the arc-shaped rod 24;

[0020] As shown in Figure 2 andFigure 3 As shown in the figure, the horizontal screw rod 21 moves through the lining 11 of the arc-shaped framework 1, that is, the horizontal screw rod 21 can rotate relative to the lining 11, and the threads on the horizontal screw rod 21 located in front of and behind the lining 11 are opposite in screw direction, and the two vertically placed moving columns 22 on the telescopic connecting device 2 are respectively threaded on the horizontal screw rod 21 in front of and behind the lining 11, and the upper end and lower end of the moving column 22 are fixedly connected to the lining 11 through the telescopic rod 4, and each moving column 22 is fixedly connected to the arc-shaped rod 24 through a plurality of connecting rods 23.

[0021] As shown in the figure, the horizontal screw rod 21 moves through the lining 11 of the arc-shaped framework 1, that is, the horizontal screw rod 21 can rotate relative to the lining 11, and the threads on the horizontal screw rod 21 located in front of and behind the lining 11 are opposite in screw direction, and the two vertically placed moving columns 22 on the telescopic connecting device 2 are respectively threaded on the horizontal screw rod 21 in front of and behind the lining 11, and the upper end and lower end of the moving column 22 are fixedly connected to the lining 11 through the telescopic rod 4, and each moving column 22 is fixedly connected to the arc-shaped rod 24 through a plurality of connecting rods 23. Figure 4 As shown in the figure, the horizontal screw rod 21 moves through the lining 11 of the arc-shaped framework 1, that is, the horizontal screw rod 21 can rotate relative to the lining 11, and the threads on the horizontal screw rod 21 located in front of and behind the lining 11 are opposite in screw direction, and the two vertically placed moving columns 22 on the telescopic connecting device 2 are respectively threaded on the horizontal screw rod 21 in front of and behind the lining 11, and the upper end and lower end of the moving column 22 are fixedly connected to the lining 11 through the telescopic rod 4, and each moving column 22 is fixedly connected to the arc-shaped rod 24 through a plurality of connecting rods 23.

[0022] When it is necessary to install the friction lining 3 on the arc-shaped framework 1, the horizontal screw rod 21 is first manually rotated so that the moving column 22 moves away from the lining 11, at this time, the two arc-shaped rods 24 on the telescopic connecting device 2 are away from the arc-shaped framework 1, at this time, the inner end surface of the friction lining 3 is abutted against the outer end surface of the arc-shaped framework 1, then the horizontal screw rod 21 is reversely rotated, at this time, the two moving columns 22 will move towards the lining 11, and at the same time, the arc-shaped rod 24 will be inserted into the arc-shaped groove 31 on the friction lining 3 through the connecting rod 23, realizing the connection of the arc-shaped framework 1 and the friction lining 3, at this time, the locking device on the telescopic rod 4 is locked, which can prevent the arc-shaped rod 24 from being separated from the arc-shaped groove 31 due to the rotation of the horizontal screw rod 21 during use, thereby affecting the use of the friction lining 3 and the arc-shaped framework 1.

[0023] At the same time, since the anti-skid column 111 is arranged on the end surface of the lining 11 in contact with the horizontal screw rod 21, the friction between the lining 11 and the horizontal screw rod 21 is increased, which can reduce the probability of self-rotation of the horizontal screw rod 21 and improve the safety performance.
