The purpose of this utility model is achieved by the following schemes:

A land rowing vehicle, comprising universal wheels, a left pedal, a vehicle frame, a right pedal, a right rowing rod, a vehicle seat, a right rear wheel, a left rear wheel and a left rowing rod, is characterized in that: The front end is equipped with universal wheels, and the two sides of the rear end of the frame are respectively equipped with right rear wheels and left rear wheels. The right pedal and the right rowing rod drive the right rear wheel to rotate, and the left pedal and the left rowing rod drive the left rear wheel. The wheels rotate, and the left and right rear wheels use the same speed or differential speed to realize the straight running or turning of the land rowing vehicle. the

Four rollers are respectively installed on the described left pedal and the right pedal, which can slide back and forth in the groove of the vehicle frame, and are connected with the left chain and the right chain by the pull rod on the pedal respectively. the

The right rowing rod and the left rowing rod are connected and fixed on the vehicle frame with pins respectively, and can swing back and forth; the lower ends of the two rowing rods are all provided with chute, wherein the chute of the right rowing rod is connected with the outer part of the right pedal. The protruding pin constitutes a moving pair, and the chute of the left rowing rod and the outward extending pin of the left pedal constitute a moving pair; in addition, the upper ends of the right rowing rod and the left rowing rod are respectively equipped with brake handles, together with the left and right brake discs, Constitutes the braking system of a land rowing vehicle. the

Described right rear wheel, left rear wheel are independent structures respectively, and single-stage flywheel is housed respectively on its rotating drum. the

The vehicle seat is installed on the rear portion of the vehicle frame, and the vehicle seat can be adjusted. the

One end of the right return spring is connected with the vehicle frame, and the other end is connected with the right rowing rod; one end of the left return spring is connected with the vehicle frame, and the other end is connected with the left rowing rod. the

The land rowing vehicle adopting the above scheme has the effect of rowing a boat in water, realizes the feasibility of rowing on land, not only achieves the effect of fitness and entertainment, but also can be used as a simple means of transportation. the

Description of drawings

Below, the utility model will be further described in conjunction with the accompanying drawings, and those skilled in the art can further understand the features and advantages of the utility model from the description. the

Figure 1, a three-dimensional schematic diagram of a land rowing vehicle;

Figure 2, a three-dimensional schematic diagram of the rear structure of the car body;

Detailed ways

As shown in accompanying drawing 1, the three-dimensional schematic diagram of the land rowing vehicle shown in this example has shown the feature of land rowing vehicle, promptly comprises universal wheel 1, vehicle frame 3, left pedal 2, right pedal 4, Parts such as right row bar 5, left row bar 21, vehicle seat 9 and left rear wheel 17, right rear wheel 10. The utility model left foot pedal 2 moves back and forth in the double bar track, drives the left chain 18 that is installed on the left chain disc 19 to move back and forth, and the chain drive drives the left rear wheel 17 to run, and the right rear wheel is the same. The left row bar 21 and the left pedal 2 constitute a slider mechanism, and the right row bar and the right pedal are the same. In this way, both hands and feet can be used to drive, and hands and feet can also be driven independently. the

As shown in accompanying drawing 2, left rear wheel 17, right rear wheel 10 are respectively independent structures: right single-stage flywheel 11 is housed on the drum of right rear axle 13; Left single-stage flywheel 15 is housed on the drum of left rear axle 16 , The flywheel has the function of one-way transmission of power, so that the two rear wheels can move straight forward at the same speed; turn at different speeds or turn around at 180 degrees or circle at 360 degrees. The brake handle on the bar and the brake discs 12, 14 constitute a braking system. The vehicle seat 9 can be adjusted back and forth to meet the needs of people of different body types. the

As can be seen from the above examples, the utility model has the following advantages:

1. The land rowing vehicle retains the rowing action and has the function of entertainment and fitness. 2. The two rear wheels have the same structure, but the driving mode is independent of each other, and the steering is realized by using the differential speed between the two rear wheels, and the steering is more flexible. 3.
