[0023] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0024] Reference Figure 1-4 The utility model provides an embodiment of a small tricycle body structure, including a frame 7, a carriage 4 is fixedly connected to the top right side of the frame 7, a knob 8 is rotatably connected to the left side of the carriage 4, a lead screw 9 is fixedly connected to the right side of the knob 8, a slide bar 13 is fixedly connected to the front and rear sides of the interior of the carriage 4, a limit plate 12 is fixedly connected to the right end of the slide bar 13, and an extension box 11 is slidably connected to the interior right side of the carriage 4.

[0025] Specifically, first, the knob 8 is turned to drive the screw 9 to rotate. Since the screw 9 is threadedly connected to the baffle 10, and the extension box 11 slides on the outside of the two slide bars 13, at the same time, the extension box 11 is limited by the limit plate 12, so that the rotation of the screw 9 drives the extension box 11 to move to the right, thereby adjusting the storage volume inside the car 4, thereby improving the practicality of the small tricycle.

[0026] The right part of the extension box 11 is rotatably connected to the baffle 10, the rear right side of the extension box 11 is slidably connected to the button 18, the left end of the button 18 is fixedly connected to the slide plate 17, the left side of the slide plate 17 is rotatably connected to the connecting rod 16, the left end of the connecting rod 16 is rotatably connected to the clamping block 14, and the rear end of the clamping block 14 is fixedly connected to the return spring 15.

[0027] Specifically, the button 18 is pressed to the left first, and the slide plate 17 is urged to move to the left. Since the slide plate 17 is rotatably connected to the connecting rod 16, and the connecting rod 16 is rotatably connected to the clamping block 14, the clamping block 14 is driven to move backward inside the extension box 11, and the return spring 15 is compressed, thereby releasing the baffle 10. Then, the user unloads the goods, resets the baffle 10, and then releases the button 18. Due to the elastic force of the return spring 15, the clamping block 14 is driven to move forward, thereby clamping the rear part of the baffle 10, so as to facilitate the subsequent user to unload the goods.

[0028] A seat 3 is fixedly connected to the upper part of the frame 7, a handlebar 2 is rotatably connected to the upper left side of the frame 7, a front wheel 1 is rotatably connected to the left side of the frame 7, two rear wheels 6 are rotatably connected to the right side of the frame 7, and two railings 5 ​​are fixedly connected to the top of the carriage 4.

[0029] Specifically, the frame 7 uses reinforced steel bars to help increase the load-bearing capacity of the frame 7, so that it can better cope with various road conditions and load conditions, improve the durability and stability of the vehicle, and through the triangular design, improve the stability of the entire vehicle body, so that the entire three-wheeled vehicle is more stable during driving.

[0030] The lead screw 9 passes through the carriage 4 and is threadedly connected to the middle of the extension box 11 , and the extension box 11 is slidably connected to the outside of the slide rod 13 .

[0031] Specifically, by rotating the knob 8 , the lead screw 9 is driven to rotate, thereby driving the extension box 11 to move to the right, so as to increase the structure of the carriage 4 .

[0032] The limiting plate 12 is slidably connected inside the extension box 11 .

[0033] Specifically, the limiting plate 12 plays a limiting role to prevent the extension box 11 from being separated from the carriage 4 during the process of moving the extension box 11 to the right.

[0034] The front periphery of the clamping block 14 is inserted into the rear of the baffle 10 , and the rear end of the return spring 15 is fixedly connected to the interior of the extension box 11 .

[0035] Specifically, the elastic force of the return spring 15 is used.

[0036] The slide plate 17 is slidably connected inside the extension box 11 .

[0037] Specifically, the slide plate 17 prevents the button 18 from being pushed out of the extension box 11 when the reset spring 15 pushes the block 14 to reset.

[0038] Working principle: When in use, first turn the knob 8 to drive the lead screw 9 to rotate. Since the lead screw 9 is threadedly connected to the baffle 10, and the extension box 11 slides outside the two slide bars 13, and at the same time, the extension box 11 is limited by the limit plate 12, so that the extension box 11 is driven to move to the right by the rotation of the lead screw 9, thereby adjusting the storage volume inside the compartment 4, thereby improving the practicality of the small tricycle;

[0039] When the cargo inside the carriage 4 needs to be unloaded, the button 18 is first pressed to the left to drive the slide plate 17 to move to the left. Since the slide plate 17 is rotatably connected to the connecting rod 16, and the connecting rod 16 is rotatably connected to the clamping block 14, the clamping block 14 is driven to move backward inside the extension box 11, and the return spring 15 is compressed to release the baffle 10. Then, the user unloads the cargo and resets the baffle 10, and then releases the button 18. Due to the elastic force of the return spring 15, the clamping block 14 is driven to move forward and clamp the rear part of the baffle 10, so as to facilitate the subsequent user to unload the cargo.

[0040] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
