When the main body frame is contacted with the ground to move, the front wheel drives the driven wheel to rotate through a transmission device such as a belt or a gear, the tail end of a brake rod connected with the surface shaft of the driven wheel rotates by taking the axis of the driven wheel as the center of a circle, the middle part of the brake rod is sleeved in the limit frame, therefore, the front end of the brake rod does telescopic motion, the front end of the brake rod is abutted against the front wheel after the tail end of the brake rod advances a certain distance to the front wheel, the front wheel is braked under the action of friction force, at the moment, the rear vehicle continues to advance, so that the front connecting rod and the rear connecting rod are jacked up to be triangular, the integral back of the caterpillar is supplied in appearance, when the rear vehicle moves to a position capable of pushing the front vehicle, the brake rod continuously rotates to drive the brake rod to rotate, and the tail end principle that the front end of the brake rod is separated from the front wheel by the front wheel, the front connecting rod drives the front vehicle to advance at an accelerated speed under the gravity of the balance weight, so that the whole effect is that the rear part of the caterpillar advances at a uniform speed, and the front part stops, advances at an accelerated speed, stops and advances at an accelerated speed.

Preferably, the front end of the brake rod is provided with a friction plate, the tail end of the friction plate is positioned in the cavity of the front end of the brake rod, and the tail end of the friction plate is connected with the inner wall of the cavity of the front end of the brake rod through a spring. Through the spring, the defect that the front end of the brake rod is too tight to prop against the front wheel, so that the friction force is too large to lock and the brake rod cannot move forwards continuously can be avoided.

Preferably, the transmission device is a belt or a gear. And mature parts are adopted, so that the cost is saved.

Preferably, a power device and a switch for controlling the power device are arranged in the rear vehicle, the power device is connected with the rear wheel, and the power device is a motor-battery device or a clockwork spring device. The rear vehicle can be manually pushed, a power device can be arranged to automatically advance, and a spring or a motor is arranged to enable young children to remotely observe the rear vehicle when the rear vehicle advances, so that the rear vehicle is more interesting.

The invention perfectly realizes the discontinuous advancing device through a simple structure, reproduces the motion state of the caterpillar, can cultivate the interest of children to the creatures, fills the blank of the toys and has good economic value.

Detailed Description

Example 1

The following describes embodiment 1 of the present invention in further detail with reference to fig. 1, 2 and 3:

an intermittent advancing device comprises a main body frame structure, wherein the main body frame structure comprises a front vehicle 4 and a rear vehicle 5, the front vehicle 4 is connected with a front connecting rod 3 through a rotating shaft, the rear vehicle 5 is connected with a rear connecting rod 2 through a rotating shaft, the front connecting rod 3 and the rear connecting rod 2 are mutually connected through the rotating shaft, a counterweight 8 is arranged on the front connecting rod 3, a front wheel 6 is arranged at the bottom of the front vehicle 4 through the rotating shaft, a rear wheel 7 is arranged at the bottom of the rear vehicle 5 through the rotating shaft, the front wheel 6 is connected with a driven wheel 9 through a transmission device 11, the driven wheel 9 is connected with the tail end of a brake rod 10 through the rotating shaft, the brake rod 10 is sleeved in a limiting frame 12, the limiting frame 12 is of a hollow frame shape and is fixed on the inner surface of the front vehicle 4, the front end of the brake rod 10 abuts against the surface of the front wheel 6 when the driven wheel 9 rotates to the position, the front end of the front wheel is separated from the surface of the front wheel 6 when the tail end rotating shaft is far away from the front wheel. The front end of the brake rod 10 is provided with a friction plate 13, the tail end of the friction plate 13 is positioned in the cavity of the front end of the brake rod 10, and the tail end of the friction plate 13 is connected with the inner wall of the cavity of the front end of the brake rod 10 through a spring 14.
