[0025] Please refer to Figure 1-4 The bottom of the frame of the trolley frame 1 is provided with a material placing slot 9, and a lifting and supporting mechanism is installed at the bottom of the frame of the trolley frame 1 along the opening direction of the material placing slot 9. The lifting and supporting mechanism comprises two groups of lifting electric rods 3 which are symmetrically arranged at the bottom of the frame of the trolley frame 1 in pairs, and the telescopic ends of each group of lifting electric rods 3 are provided with side supporting plates 4, and a bottom supporting platform 5 which is opposite to the material placing slot 9 is provided between the two groups of side supporting plates 4. By controlling the telescopic ends of the lifting electric rods 3 to extend, the bottom supporting platform 5 is pushed down to keep it flush with the ground, so that the staff can intuitively move the furniture to the bottom supporting platform 5, without the need to move the furniture greatly, the transportation safety is better, and the transportation strength is lower. After the transportation is completed, it is only necessary to control the telescopic ends of the lifting electric rods 3 to retract to drive the bottom supporting platform 5 to move up, so that the furniture can be supported in the air for transportation.

[0026] A conical platform 10 is arranged at the front end of the frame of the bottom support platform 5, and a plurality of groups of guide rollers 11 are arranged at equal intervals inside the frame of the bottom support platform 5, and the roller shafts of the guide rollers 11 protrude from the surface of the bottom support platform 5. When transporting and loading furniture, the conical platform 10 is arranged on the top of the bottom support platform 5, so that the furniture can be easily pushed onto the bottom support platform 5. While pushing and loading the furniture, the roller pressure conveying of the guide rollers 11 can be used to conveniently push the furniture onto the bottom support platform 5, thereby reducing the control intensity of the staff.

[0027] The inner frame back plate of the trolley frame 1 is symmetrically installed with a back-supporting cushion 6, and the two sides of the inner frame of the trolley frame 1 are symmetrically provided with a clamping electric rod 7, and the outer side of the body of the clamping electric rod 7 is provided with a side-mounted bracket 71 fixedly connected to the trolley frame 1. The pressure cushion 84 and the back-supporting cushion 6 are both made of rubber pad material. After the furniture is moved to the transport rack, the back of the furniture is leaned against the back-supporting cushion 6, and the telescopic end of the clamping electric rod 7 is controlled to contract, so that the pressure cushion 84 in the pressure limiting mechanism 8 is translated and slid, and pressed on the front end of the furniture, forming a front-to-back clamping fixed state with the back-supporting cushion 6, thereby improving the safety and stability of furniture transportation.

[0028] The telescopic end of the clamping electric rod 7 is provided with a pressure limiting mechanism 8, which includes a central axis 81 installed at the top of the telescopic rod of the clamping electric rod 7, one end of the shaft of the central axis 81 is rotatably connected with a rotating sleeve 82, and a rotating swing arm 83 is provided on the outside of the sleeve of the rotating sleeve 82, and a pressure cushion 84 made of the same material as the back support cushion 6 is provided on the arm back plate of the rotating swing arm 83, the central axis 81 is a cavity structure, and an arm force pull rod 85 is inserted into the cavity of the central axis 81, a pull handle 86 is provided at one end of the arm of the arm force pull rod 85, and a guide slide 88 is provided at the other end of the arm of the arm force pull rod 85, a spline shaft 89 slidably connected to the central axis 81 is provided on the outside of the frame of the guide slide 88, a spline groove 810 matched with the spline shaft 89 is provided on the inner wall of the sleeve of the rotating sleeve 82, and a spline groove 810 matched with the spline shaft 89 is provided on the outer side of the arm of the arm force pull rod 85. The compression spring 87 is pressed against each other, and the arm force pull rod 85 is elastically pressed against the central axis 81 through the compression spring 87. After the furniture is transported and loaded, the pull handle 86 can be pulled to drive the guide slide 88 at the other end of the arm force pull rod 85 to slide and move the spline shaft 89 out of the spline groove 810 in the rotating sleeve 82 to release the locked engagement state. At this time, the rotating sleeve 82 is pushed to rotate and swing, so that the combination of the rotating swing arm 83 and the counter-pressure cushion 84 is transformed from a vertical state to a horizontal state, so as to clamp and limit the furniture to prevent it from tilting forward, falling off and sliding during transportation. After the adjustment is completed, the pull handle 86 is released, and the elastic force of the compression spring 87 is used to reset the arm force pull rod 85, so that the spline shaft 89 is re-inserted into the spline groove 810 to form a locked state, so that the rotating swing arm 83 and the counter-pressure cushion 84 remain in a horizontal state, and the furniture is counter-limited and fixed.

[0029] The working principle of the utility model is as follows: when the furniture is being transported for trade, the transport rack is pushed to the side of the furniture, and then the telescopic end of the lifting electric rod 3 is extended to push the bottom support platform 5 down and keep it flush with the ground, so that the staff can intuitively move the furniture to the bottom support platform 5, without the need to move the furniture significantly, and the transportation is safer and more flexible. After the transportation is completed, it is only necessary to control the telescopic end of the lifting electric rod 3 to retract and drive the bottom support platform 5 to move up, so that the furniture can be supported in the air for transportation. When the furniture is moved to the bottom support platform 5, the clamp is made to lean against the back support cushion 6, and the furniture is moved to the bottom support platform 5. The rotating swing arm 83 in the pressure limit mechanism 8 is combined with the pressure pad 84 to transform from a vertical state to a horizontal state. At this time, the telescopic end of the clamping electric rod 7 is controlled to contract, so that the pressure pad 84 in the pressure limit mechanism 8 can slide horizontally and be pressed against the front end of the furniture to form a front and rear clamping fixation form with the back support pad 6 to improve the safety and stability during furniture transportation. After transporting the furniture to the specified position, it is only necessary to control the clamping electric rod 7 to move the pressure limit mechanism 8 away, and control the lifting electric rod 3 to move the bottom support platform 5 down to be flush with the ground, so that the clamp can be conveniently transported and removed. The operation is simple and convenient, and the operation safety is better.
