[0022] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-2 The detachable two-purpose tricycle comprises a front body 1, a rear body 2, two front wheels 3, a rear wheel 4, a handlebar 5 and a seat 6. The two front wheels 3 are respectively mounted on both sides of the front body 1, the rear wheel 4 is mounted on the rear body 2, the handlebar 5 is mounted on the front body 1, and the seat 6 is mounted on the rear body 2. The rear side of the front body 1 is fixedly connected with a first connecting rod 7, and the front side of the rear body 2 is fixedly connected with a second connecting rod 8. An installation connection mechanism 9 is provided between the first connecting rod 7 and the second connecting rod 8, and the installation connection mechanism 9 detachably connects the first connecting rod 7 and the second connecting rod 8 into one. Through the mutual cooperation of the installation connection mechanism 9, the first connecting rod 7 and the second connecting rod 8, the tricycle can separate the front body 1 and the rear body 2 and transform into a cart, which is convenient for pushing, turning and turning in a narrow area. In addition, a cart bucket 12 or a basket and other accessories are installed on the front body 1. After the three-wheeled vehicle is disassembled, the design of the cart bucket 12 in combination with the front body 1, the handlebars 5 and the front wheels 3 can form a two-wheeled cart for users to push objects. Users can choose to use the entire tricycle or the disassembled two-wheeled cart according to usage conditions, thereby increasing functionality and selectivity.

[0024] like Figure 3-4 As shown, the installation connection mechanism 9 includes an upper semicircular block 91, a lower semicircular block 92 and an inner threaded ring 93. The upper semicircular block 91 and the lower semicircular block 92 are opposite to each other and have the same size. The lower semicircular block 92 is integrally formed with the end of the first connecting rod 7. The upper semicircular block 91 is threadedly connected with the end of the second connecting rod 8. The surfaces of the upper semicircular block 91 and the lower semicircular block 92 are both provided with external threads adapted to the inner threaded ring 93. The inner threaded ring 93 is threadedly connected with the combined structure of the upper semicircular block 91 and the lower semicircular block 92. Rotating the inner threaded ring 93 to separate it from the upper semicircular block 91 and the lower semicircular block 92 can realize the separation of the first connecting rod 7 and the second connecting rod 8, and disassembling the tricycle is very simple to operate and has a simple structural design, which is easy to produce and process.

[0025] In addition, the first connecting rod 7 and the second connecting rod 8 are round rods with the same diameter, and the combined diameter of the upper semicircular block 91 and the lower semicircular block 92 is the same as that of the first connecting rod 7 and the second connecting rod 8 and can form a straight line to ensure the consistency and aesthetics of the connection. The surface of the inner thread ring 93 is provided with an anti-slip layer for easy rotation.

[0026] Furthermore, in order to increase the stability of the connection between the upper and lower semicircular blocks, the bottom of the upper semicircular block 91 is fixedly connected to a limiting block 94, and the top of the lower semicircular block 92 is provided with a limiting groove 95 adapted to the limiting block 94. The limiting block 94 is plugged into the limiting groove 95 to achieve mutual limitation of the upper and lower semicircular blocks. In conjunction with the internal threaded sleeve 93, the connection between the first connecting rod 7 and the second connecting rod 8 is more stable.

[0027] The surfaces of the first connecting rod 7 and the second connecting rod 8 are fixedly connected to the limiting ring 96. The limiting ring 96 on the first connecting rod 7 is located at the end of the first connecting rod 7 close to the lower semicircular block 92, and the limiting ring 96 on the second connecting rod 8 is located at the length of one inner thread ring 93 from the upper semicircular block 91. The surface of the second connecting rod 8 and between the limiting ring 96 and the upper semicircular block 91 are also provided with external threads adapted to the inner thread ring 93. The limiting ring 96 is used to limit the range of motion of the inner thread sleeve 93. The design of the inner thread ring 93 and the outer thread makes the disassembly process more intuitive and easy to operate, and the user can complete the operation without professional skills.

[0028] A headlight 10 is installed on the front side of the front body 1 of the vehicle, and an oblique support rod 11 is provided on the rear body 2 of the vehicle. The oblique support rod 11 is fixedly connected to the bottom of the second connecting rod 8 to increase stability.

[0029] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
