[0022] In order to make the technical concept and advantages for the invention to achieve its invention purpose clearer, the technical solution of the present utility model will be further described in detail below with reference to the attached drawings. It should be understood that the following embodiments are only used to explain and illustrate the preferred implementation modes of the present utility model, and should not constitute a limitation to the scope of protection required by the patent of the present utility model. Embodiment
[0023] Refer to Figures 1-7 , for the portable, collapsible and stowable folding chair trailer of the present utility model, its body includes a trailer platform A and a folding chair B. The trailer platform A is composed of a fixed pipe shaft 7 and a sliding pipe shaft 5 for installing wheels 2 which are nested and connected to form the axle and wheel part of the trailer; two wide-mouth V-shaped left and right frame bodies made of square steel (thickened rectangular steel pipe) are opposite to each other, with their front ends hinged, and the other ends are respectively connected to the fixed pipe shaft 7 forming the axle or the two sliding pipe shafts 5 on both sides of the fixed pipe shaft to form a stowable trailer frame 1. The two rear legs of the folding chair B are respectively fixed on the two sliding pipe shafts 5 on both sides of the fixed pipe shaft 7, and a longitudinal sliding groove 4 for the front leg of the folding chair B is provided on a section of the two wide-mouth V-shaped left and right frame bodies forming the frame and connecting the fixed pipe shaft 7.
[0024] The sliding pipe shaft 5 and the fixed pipe shaft 7 are nested and slidably connected to each other, and a round pipe shaft positioning steel ball 6 is provided at the connection. A towing connector is provided at the front end of the trailer frame 1. The other ends of the two wide-mouth V-shaped left and right frame bodies made of square steel are respectively arranged on the fixed pipe shaft 7 through the frame axle connecting pipe 16 and are slidably connected relative to the fixed pipe shaft 7. The frame axle connecting pipe 16 is an active joint, which facilitates the left and right sliding of the left and right frame bodies along the fixed pipe shaft 7.
[0025] Alternatively, the other ends of the two wide-mouth V-shaped left and right frame bodies made of square steel are respectively hinged to the two sliding pipe shafts 5 on both sides of the fixed pipe shaft 7. When the folding chair is stored, the left and right frame bodies move towards the middle along the fixed pipe shaft 7 together with the sliding pipe shafts 5 and the wheels (simultaneously with the two rear legs of the folding chair). At this time, the front legs of the folding chair B are stored backward and towards the middle from the longitudinal sliding groove 4.
[0026] For the portable collapsible folding chair trailer described above, the two wide-mouth V-shaped left and right frame bodies at the front end of the trailer frame 1 are hinged through a cylindrical towing pipe 3, and a towing connection hole is provided thereon; an auxiliary load-bearing universal wheel 9 is provided below the front end of the trailer frame 1. Embodiment
[0027] The portable collapsible folding chair trailer of the present utility model includes a trailer platform A (which can be stored together with the folding chair) and a folding chair B. The trailer platform A is composed of a stainless steel rectangular pipe and a stainless steel fixed pipe shaft 7 to form a frame. Stainless steel sliding pipe shafts 5 are installed at both ends of the fixed pipe shaft 7 in a matching manner. Wheels 2 are installed on the stainless steel sliding pipe shafts 5. The stainless steel sliding pipe shafts 5 and the fixed pipe shaft 7 are cooperated through round pipe shaft positioning marbles 6. The front end of the frame platform A is hinged through a stainless steel cylindrical towing pipe 3, and an auxiliary load-bearing universal wheel 9 is provided below the front end of the trailer frame 1. A longitudinal sliding groove 4 for the front legs of the folding chair B is provided at a section of the two wide-mouth V-shaped left and right frame bodies that connect the fixed pipe shaft 7. The folding chair B is composed of a folding bracket 10 and a canvas seat cover 11.
[0028] A multi-vehicle series towing pipe 8 can be provided in the middle of the fixed pipe shaft 7. Multiple vehicles can be connected in series and towed in a line, which is convenient for shopping. The wheels are pneumatic rubber wheels with a load capacity of more than 100 kg. The trailer platform can be hung and towed with various types of wheelchairs and ordinary two- or three-wheeled electric vehicles through a stainless steel round towing pipe. Adding a small front-wheel single-wheel electric vehicle can turn it into a small electric tricycle.
[0029] The stainless steel sliding pipe shaft 5 can slide left and right on the stainless steel fixed pipe shaft 7, and the round pipe shaft positioning marble 6 can fix the sliding distance of the stainless steel sliding pipe shaft 5. The auxiliary load-bearing universal wheel 9 plays a role in flexible steering during towing.
[0030] Such as Figures 3-7As shown in the figure, the four chair legs of the folding chair B can move telescopically forward, backward, left and right on the portable trailer platform A. In the figure, the reference numeral 12 is the unfolding position of the front chair leg, 13 is the unfolding position of the rear chair leg, 14 is the retracting position of the front chair leg, and 15 is the retracting position of the rear chair leg. The two front legs of the folding moon recliner can slide back and forth along the longitudinal sliding groove 4 of the chair legs on the trailer platform until they are pulled out of the groove. The two rear chair legs fixed on the stainless steel sliding tube shaft 5 can rotate 270 degrees in the reverse direction along the stainless steel fixed tube shaft 7 when the chair is retracted, so that the folding chair B and the trailer platform A are completely folded and integrated, thus facilitating storage.
[0031] The main body of the portable, collapsible and foldable chair trailer of the present utility model is composed of a trailer platform and a folding chair. After the recliner is stored and rotated 270 degrees in the reverse direction, it can be completely folded, with a small volume, convenient for storage and easy to carry. It can be matched with various types of wheelchair towing, can be towed by a wheelchair and can be placed under the wheelchair after being completely folded and stored, solving the problem that there is nowhere for the disabled caregiver to sit.
[0032] The above description is only the preferred embodiment of the present utility model and does not constitute a limitation to the present utility model. Under the guidance of the prior art, those skilled in the art can make other modifications to the implementation of the present utility model without creative work. Any modification made within the spirit and principle of the present utility model or any simple replacement or equivalent replacement using the conventional technical means in the art shall be included in the protection scope of the present utility model.
