The center of the positioning wheel (9) is provided with a mounting hole (905), and the end part of the connecting shaft 22 is directly inserted into the mounting hole 905, so that the connecting shaft 22 and the positioning wheel 9 are fixedly connected. In this embodiment, the bidirectional reset mechanism 6 is of an integrated structure. In addition, a positioning mechanism and a bidirectional reset mechanism can be separately and independently designed, and the positioning mechanism feeds back 5 gears of the independent brake controller: the "4" bit, the "3" bit, the "0" bit, the "2" bit, and the "1" bit.
The individual brake controller is provided with 5 gears: the positions of the drum wheel mechanism 2 and the positioning wheel 9 are fixedly connected through a connecting shaft 22, and the gears of the operating handle 1 correspond to the positioning grooves on the positioning wheel 9 one by one, so that the bidirectional reset mechanism 6 can clearly feedback 5 gears set by the single brake controller.
The working process and principle of the invention are as follows:
when the operation is not performed (in an initial state), the operation handle 1 is stopped at the "0" position, the operation handle 1 is in a vertical state, the protrusion 1001 on the reset lever 10 is engaged with the reset groove 904, and the positioning ball 19 of the positioning mechanism 15, 19, 21 is engaged with the second positioning groove 902 corresponding to the "0" position.
When the operating handle 1 is operated to the "4" position, the drum mechanism 2 and the cam mechanism 7 rotate synchronously, the corresponding micro switches 5 act synchronously, as shown in fig. 3, the positioning wheel 9 rotates counterclockwise until the protrusion 1001 on the reset rod 10 moves out of the reset groove 904 to the left arc (at this time, the second spring 17 is compressed), and the positioning ball 19 moves out of the second positioning groove 902 to the first positioning groove 901. After the operating handle 1 is released, because the positioning balls 19 are clamped in the first positioning grooves 901, the acting force exerted on the first positioning grooves 901 by the positioning balls 19 of the positioning mechanisms 15, 19 and 21 is greater than the acting force exerted on the reset rod 10 transmitted by the second rod 16 by the second spring 17, and therefore the positioning wheel 9 is locked in the "4" position by the positioning mechanisms 15, 19 and 21, and the operating handle 1 is stopped in the "4" position. At which time a manual reset is required.
Similarly, when the operating handle 1 is operated to the "1" position, the drum mechanism 2 and the cam mechanism 7 rotate synchronously, and the corresponding micro-switches 5 act synchronously, as shown in fig. 3, the positioning wheel 9 rotates clockwise until the protrusion 1001 on the reset rod 10 moves out of the reset groove 904 to the right arc (at this time, the first spring 13 is compressed), and the positioning ball 19 moves out of the second positioning groove 902 to the third positioning groove 903. After the operating handle 1 is released, the positioning ball 19 is clamped in the third positioning groove 903, and the acting force exerted on the third positioning groove 903 by the positioning ball 19 of the positioning mechanism 15, 19, 21 is greater than the acting force exerted on the reset rod 10 by the first spring 13, which is transmitted to the first rod 12, so that the positioning wheel 9 is locked in the position "1" by the positioning mechanism 15, 19, 21, and the operating handle 1 is stopped in the position "1". At which time a manual reset is required.
When the operating handle 1 is operated to the "3" position, the drum mechanism 2 and the cam mechanism 7 rotate synchronously, the corresponding micro switches 5 act synchronously, as shown in fig. 3, the positioning wheel 9 rotates counterclockwise until the protrusion 1001 on the reset rod 10 moves out of the reset groove 904 to the left bending point (at this time, the second spring 17 is compressed), and the positioning ball 19 moves out of the second positioning groove 902 to a position between the first positioning groove 901 and the second positioning groove 902. When the operating handle 1 is released, the acting force exerted on the positioning wheel 9 by the positioning balls 19 of the positioning mechanisms 15, 19 and 21 is smaller than the acting force exerted on the reset lever 10 by the second spring 17 and transmitted by the second rod 16, so that the reset lever 10 drives the positioning wheel 9 to rotate clockwise until the convex part 1001 on the reset lever 10 returns to the reset groove 904 and the positioning balls 19 return to the second positioning groove 902, and the positioning wheel 9 is positioned at the position of 0. Meanwhile, the drum wheel mechanism 2 and the cam mechanism 7 return along with synchronous rotation, the corresponding micro-switches 5 synchronously act and reset, the operating handle 1 stops at the position of 0, and the operating handle 1 is in a vertical state. It can be seen that when the operating handle 1 is manipulated to the "3" position, the operating handle 1 can be automatically reset to the "3" position when the external force is removed.
Similarly, when the operating handle 1 is operated to the "2" position, the drum mechanism 2 and the cam mechanism 7 rotate synchronously, and the corresponding micro-switches 5 act synchronously, as shown in fig. 3, until the protrusion 1001 on the reset rod 10 moves out of the reset groove 904 to the right bending point (at this time, the first spring 13 is compressed), and the detent ball 19 moves out of the second detent 902 to a position between the third detent 903 and the second detent 902. When the operating handle 1 is released, the acting force exerted on the positioning wheel 9 by the positioning balls 19 of the positioning mechanisms 15, 19 and 21 is smaller than the acting force exerted on the reset lever 10 by the first spring 13, which is transmitted by the first rod 12, so that the reset lever 10 drives the positioning wheel 9 to rotate counterclockwise until the protrusions 1001 on the reset lever 10 return to the reset groove 904 and the positioning balls 19 return to the second positioning grooves 902, and at this time, the positioning wheel 9 is positioned at the position "2". Meanwhile, the drum wheel mechanism 2 and the cam mechanism 7 return along with synchronous rotation, the corresponding micro-switches 5 synchronously act and reset, the operating handle 1 stops at the position of 2, and the operating handle 1 is in a vertical state. It can be seen that when the operating handle 1 is manipulated to the "2" position, the operating handle 1 can be automatically reset to the "2" position when the external force is removed.
While the present invention has been described with reference to the embodiments shown in the drawings, the present invention is not limited to the embodiments, which are illustrative and not restrictive, and it will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
