Description

Technical Field

[0001] This utility model relates to multiple technical fields such as tool carts, camping vehicles, and bicycle trailers, specifically a multi-functional tool cart that can be towed by bicycle or manually. Background Technology

[0002] As people's leisure and lifestyle habits change, outdoor activities such as cycling and camping are becoming increasingly diverse. Currently, camping vehicles and utility vehicles on the market exist independently, each with only one function. They can only be used independently and cannot be towed with a bicycle, limiting their operating distance. Moreover, manually towing them is extremely physically demanding. How to solve these problems is the challenge faced by this utility model. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a multi-functional tool vehicle that can be towed by bicycle or manually. It combines the versatility of a campervan and a tool trailer, and can be towed by bicycle or manually, offering excellent cost-effectiveness.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A multi-functional utility cart that can be towed by bicycle and manually includes a frame body and a connecting component. The frame body includes a base and four railings, namely two side rails, a front rail, and a rear rail. The two side rails are rotatably connected to the left and right sides of the base. The front rail and the rear rail are connected to the front and rear ends of the two side rails through a plug-in structure to form a frame. The frame body is provided with a rotatable and foldable pull handle. The connecting component is an irregularly shaped component, and its two ends are respectively connected to the pull handle and the bicycle frame, realizing the rotatable connection between the utility cart and the bicycle.

[0006] Furthermore, a front support leg is rotatably connected to the bottom front end of the frame body, and two tires are rotatably connected to both sides of the bottom of the frame body.

[0007] Furthermore, the pull handle includes a fixed rod, a rotating connector, and a pull rod. The fixed rod is fixed to the bottom front end of the frame body, and the fixed rod and the pull rod are rotatably connected through the rotating connector.

[0008] Furthermore, the rotating connector includes two connecting parts whose angles are adjustable relative to each other, with a control lock in the middle. The angle between the two connecting parts can be adjusted and locked arbitrarily by means of the control lock.

[0009] Furthermore, one end of the connector is provided with a locking ring for connecting to the bicycle frame, and the other end is provided with a rotating support column. The end of the pull rod is provided with a fisheye bearing. The rotating support column and the fisheye bearing cooperate to realize the rotating connection between the bicycle and the tool cart and allow for multi-angle adjustment.

[0010] Furthermore, the main body of the connector is integrally injection molded.

[0011] Furthermore, a cloth bag for carrying items is provided around the frame of the main body of the vehicle.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are:

[0013] (1) The multi-functional tool vehicle of this utility model realizes the functions of a campervan and a tool vehicle. It can be used independently and can be towed by bicycle or pushed and pulled by hand, with extremely high cost performance.

[0014] (2) The multi-functional tool cart of this utility model realizes the function of a trailer, and the special-shaped connecting parts make the towing and turning smooth.

[0015] In summary, this utility model's multi-functional tool cart has multiple uses and multiple ways of use, allowing consumers to enjoy the functionality of multiple different types of vehicles for the price of only one vehicle, resulting in extremely high cost-effectiveness, saving money and being environmentally friendly.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] refer to Figure 1-4 The diagram shows a structural schematic of a specific embodiment of a multi-functional tool cart that can be towed by bicycle and manually. It includes a frame body 10 and a connecting component 20. The frame body 10 includes a base 11 and four railings: two side rails 12, a front rail 13, and a rear rail 14. The base 11 is rotatably connected to the two side rails 12 on its left and right sides by screws. The front rail 13 and rear rail 14 are connected to the front and rear ends of the two side rails via a plug-in structure to form a frame. Specifically, the side rails 12 have insertion holes, and the front and rear rails are designed as U-shaped structures with their ends inserted into the insertion holes for fixation. A cloth bag 40 for carrying items is provided around the frame of the frame body 10. The front of the frame body 10 has a rotatable and foldable pull handle 30. The connecting component 20 is an irregularly shaped part, with both ends connected to the pull handle 30 and the bicycle frame, respectively, to achieve a rotatable connection between the tool cart and the bicycle.

[0026] The bottom front end of the frame body 10 is rotatably connected to a front support leg 15, and the bottom sides of the frame body 10 are rotatably connected to two tires 16.
