Description

Technical Field

[0001] This utility model relates to a towing device, specifically a finished tricycle interconnected towing device. Background Technology

[0002] Existing tricycle towing devices come in a wide variety of specifications and styles, and rely on adjusting screws to adjust the fit width. Their dimensions are too large and varied, and their operation is complicated. When the front space of a vehicle with a cab is small, there are problems such as interference and incompatibility, and their applicability is not wide.

[0003] Currently, a utility model patent with publication number CN221113386U discloses a portable electric tricycle trailer connector, including a rear-end connection mechanism. The rear-end connection mechanism is fitted with a movable shaft, which passes through a fixed connecting rod and a crossbar and is connected to them by bolts. A wheel connection mechanism is installed on the crossbar away from the rear-end connection mechanism. By setting up the rear-end connection mechanism, the movable shaft, and the wheel connection mechanism, electric tricycles can be linked together one by one for movement. Workers only need to control the first vehicle to transport several vehicles, which is not only convenient and fast but also saves costs.

[0004] As can be seen from the above-disclosed technical content, as prior art, the utility model with announcement number CN221113386U connects electric tricycles one by one for movement by setting a rear connecting mechanism, a moving axle and a wheel connecting mechanism. However, the opening and closing of the fixing rod of this patent requires turning the adjusting rod. Since the two sides of the adjusting rod are threadedly connected to the nuts of the third mounting groove, the distance between the adjusting rod and the nuts can be adjusted by rotating the adjusting rod. The operation is cumbersome, time-consuming and not very convenient to use. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a prefabricated tricycle interconnected towing device, which can efficiently transfer prefabricated tricycles of different shapes and sizes, and effectively simplify the operation steps.

[0006] To achieve the above objectives, this utility model provides a finished tricycle interconnected towing device, comprising a hook, an inner liner, a clamp, a towing vertical tube, and a towing horizontal tube. The hook is fixedly connected to the clamp, which is movably connected to one end of the towing vertical tube via a pivot. The other end of the towing vertical tube is welded to the middle of the towing horizontal tube. One end of the towing horizontal tube is fixedly connected to a clamping arm two, and the other end of the towing horizontal tube is fixedly connected to a U-shaped seat. The U-shaped seat is movably mounted with a clamping arm one via a pivot. The ends of clamping arms one and two are provided with clamping sleeves that fit over the front axle of the tricycle. A parking mechanism is fixedly mounted in the middle of clamping arm two via fasteners, and the parking cable of the parking mechanism is fixedly connected to clamping arm one via fasteners.

[0007] In addition, the finished tricycle interconnected towing device proposed according to the above embodiments of this utility model may also have the following additional technical features:

[0008] As a further improvement of this utility model, the hook is provided with an inner lining.

[0009] As a further improvement of this utility model, the clamping arm one and clamping arm two have the same structure and are symmetrical to each other.

[0010] As a further improvement of this utility model, the dragging vertical tube, dragging horizontal tube, clamping arm one and clamping arm two are all made by cutting square tubes.

[0011] As a further improvement of this utility model, the hook is provided with reinforcing ribs on the outside.

[0012] By means of the above solution, this utility model has at least the following advantages: the opening and closing of clamping arm one and clamping arm two can be quickly controlled by the parking mechanism, without the need for rotation adjustment to adapt the width. The angle of the handbrake of the parking mechanism is automatically adapted directly. The parking mechanism has a built-in locking function, which greatly increases the versatility and ease of operation of the device. The opening width can be controlled by the combination of dragging the vertical tube, dragging the horizontal tube, clamping arm one and clamping arm two, reducing the overall size of the device. It can meet the needs of efficient transfer of all types of tricycles with different shapes and sizes, and effectively simplify the operation steps. Attached Figure Description

[0017] The following description, in conjunction with the accompanying drawings, describes the finished product of this utility model: a connected towing device for tricycles.

[0018] In Embodiment 1 of this application, as Figure 1 and Figure 2As shown, the finished product, a three-wheeled vehicle interconnected towing device (hereinafter referred to as "the present invention"), includes a hook 1, which is fixedly connected to a clamping plate 3. The clamping plate 3 is movably connected to one end of a towing vertical tube 4 via a rotating shaft. The other end of the towing vertical tube 4 is welded to the middle of a towing horizontal tube 5. One end of the towing horizontal tube 5 is fixedly connected to a clamping arm 2 8, and the other end of the towing horizontal tube 5 is fixedly connected to a U-shaped seat 6. The U-shaped seat 6 is movably mounted with a clamping arm 1 7 via a rotating shaft. The ends of the clamping arm 1 7 and the clamping arm 2 8 are provided with clamping sleeves 9 that fit over the front axle of the three-wheeled vehicle. A parking mechanism 10 is fixedly mounted in the middle of the clamping arm 2 8 via fasteners. The parking cable 11 of the parking mechanism 10 is fixedly connected to the clamping arm 1 7 via fasteners.

[0019] A portable electric tricycle trailer connector (hereinafter referred to as "the patent") with utility model announcement number CN221113386U connects electric tricycles one by one for movement by setting up a tail connection mechanism, a moving shaft and a wheel connection mechanism. However, the opening and closing of the fixing rod of the patent requires turning an adjusting rod. Since the two sides of the adjusting rod are threaded to the nuts of the third mounting groove, the distance between the adjusting rod and the nuts can be adjusted by rotating the adjusting rod. The operation is cumbersome, time-consuming and not very convenient to use. In contrast, the present invention quickly controls the opening and closing of the clamping arm 7 and the clamping arm 8 through the parking mechanism 10. There is no need to rotate to adjust the fitting width. The handbrake of the parking mechanism 10 is used to automatically adapt the angle. The parking mechanism 10 has a built-in locking function, which greatly increases the versatility and ease of operation of the device.

[0020] This second embodiment is basically the same in structure as the first embodiment, the difference being that, as Figure 2 As shown, the hook 1 has an inner liner 2 inside, which effectively prevents the hook 1 from scratching the car paint.

[0021] To further optimize the working efficiency of this application, the clamping arm 7 and clamping arm 8 have identical structures and are symmetrical to each other. To reduce production costs, the dragging vertical tube 4, dragging horizontal tube 5, clamping arm 7, and clamping arm 8 are all made by cutting square tubes. To improve the strength of the hook 1, the hook 1 is provided with reinforcing ribs on the outside.

[0022] When this utility model is used, its specific operation is as follows:

[0023] When efficient transfer of finished tricycles is required, one transfer vehicle typically tows 5-6 finished vehicles together for transfer. Before transfer, if the difference in front shock absorber width between the vehicles is too large and exceeds the parking brake travel, and the parking mechanism cannot tighten even when pulled to its maximum, the length of the steel cable of the parking mechanism 10 should be adjusted to increase the opening distance between clamping arm 7 and clamping arm 8 to achieve a suitable width. Under normal circumstances, no adjustment is required.

[0024] When using, such as Figure 3As shown, the rear clamping head 9 is placed on the front axle of the rear vehicle, the parking mechanism 10 is pulled, the cable or wire rope of the parking mechanism 10 is tightened, and the clamping arm 7 clamps, so that the clamping head 9 at the rear end of the clamping arm 7 and the clamping arm 8 is fixed to the front axle of the rear vehicle; the hook 1 with the inner liner 2 for protection is fastened to the footrest crossbeam of the rear tail door of the front vehicle, and the rear vehicles are connected in sequence.

[0025] During disassembly, press the front button of the parking mechanism 10 to release the self-locking mechanism, reset the parking mechanism 10, open the clamping arm 1 7 and clamping arm 2 8, remove the clamping sleeve 9 from the front wheel axle of the rear vehicle, remove the front hook 1 from the rear tailgate footrest crossbeam, and retract the towing mechanism.

[0026] In summary, the finished tricycle interconnected towing device of this utility model embodiment can quickly control the opening and closing of clamping arm 7 and clamping arm 8 through the parking mechanism 10. There is no need to rotate and adjust the fit width. The handbrake of the parking mechanism 10 is used to automatically adjust the angle. The parking mechanism 10 has a built-in locking function, which greatly increases the versatility and ease of operation of the device. The opening width is controlled by the combination of dragging the vertical tube 4, dragging the horizontal tube 5, clamping arm 7 and clamping arm 8, reducing the overall size of the device. It can meet the needs of efficient transfer of finished tricycles of different shapes and sizes, and effectively simplify the operation steps.

[0027] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the invention is limited to these examples; within the framework of the invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the invention as described above, which are not provided in detail for the sake of brevity. Any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the invention should be included within the scope of protection of the invention.
