Detailed ways

The present invention relates to a multi-link transmission device, [see Figure 1] mainly includes:

A control group 1 is used to control the structure of the transmission group 2. It is mainly composed of a bearing seat 11, a receiving block 12, a receiving hole 13, a control plate 14, a control hole 15 and a control end 16. At least one bearing seat 11 is provided. An assembly plate 111 can be provided on the top of the bearing seat 11 to be combined with the bottom of an article, and a receiving block 12 is pierced in the bearing seat 11, and a receiving hole 13 is provided in the receiving block 12, and the receiving hole 13 can correspond to a control The control hole 15 in the plate 14, the control plate 14 is set on the side of the bearing seat 11, and the transmission rod 21 of a transmission group 2 can pass through the receiving hole 13 and the control hole 15, and is locked on the control plate 14 , and the two ends of the control board 14 can be set as the control end 16 respectively, so that the transmission rod 21 can be controlled to rotate when the control end 16 is stepped on;

A transmission group 2, which can control multiple mechanisms by means of transmission, is mainly composed of a transmission rod 21, a rotating piece 22 and a plurality of connecting rods 23. The transmission rod 21 can be inserted into the receiving hole 13 of the control group 1 and control In the hole 15, the transmission rod 21 can be set as a polygonal rod body, and the receiving hole 13 and the control hole 15 can be matched to be a polygonal hole. By this, the control board 14 can be stepped on to control the transmission rod 21 The rotation is more stable, and at least one rotating piece 22 can be nested on the transmission rod 21, and then two connecting rods 23 can be pivotally connected on each rotating piece 22, and the other ends of the connecting rods 23 are then pivotally connected respectively. On a predetermined mechanism, to utilize connecting rod 23 to drive this mechanism. the

A plurality of wheel sets 3 can be controlled by means of transmission, and the other ends of the connecting rods 23 are respectively pivoted on the wheel sets 3 so that the connecting rods 23 can drive the wheel sets 3 to perform braking action. the

In the multi-link transmission device of the present invention, [please refer to Fig. 3], the transmission device can control multiple mechanisms to act at the same time. Two rotating pieces 22 are mainly assembled on the transmission rod 21 of the transmission group 2, and two connecting rods 23 are respectively arranged on the two rotating pieces 22, so that the four connecting rods 23 can respectively pivot the wheel set 3 , to complete the assembly of the wheel set 3 and the transmission set 2. In addition, [please refer to FIG. Each receiving block 12 is assembled in a bearing seat 11, and one of the two ends of the transmission rod 21 must pass through the receiving hole 13 and the control hole 15 on a control board 14 at the same time, and the transmission rod 21 is locked in the control hole 15 Inside, at last the assembling plate 111 on the bearing seat 11 at the two ends of the transmission rod 21 and the four wheel sets 3 are simultaneously locked on the bottom of a predetermined article, and then they can be used as a wheel set. The transmission device of the present invention can cooperate with all Combining items to increase or decrease the number of combined mechanisms, so it is assumed that six wheel sets 3 need to be used, three rotating pieces 22 need to be nested on the transmission rod 21, and eight wheel sets 3 need to be used if eight wheel sets 3 are used.
