Detailed Description
The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
1-6, The side plate connecting structure for expanding the carriage comprises a first mounting block 1, a second mounting block 2 and a connecting body 3, wherein the connecting body 3 is made of elastic materials, the connecting body 3 is connected with the first mounting block 1 and the second mounting block 2, the first mounting block 1 is connected with an upper plate, and the second mounting block 2 is connected with a lower plate; the lower surface of the first mounting block 1 is provided with a first supporting part 11, and the upper surface of the second mounting block 2 is provided with a second supporting part 21; when the side panels are unfolded, the first support 11 acts on the second support 21. When in actual use, the upper end of the upper plate and the lower end of the lower plate are hinged with the top plate and the bottom plate, and the side plates are driven to be unfolded by lifting the top plate.
In an embodiment, as shown in fig. 1 to 6, the second supporting portion 21 is a circular arc groove, and the first supporting portion 11 is a circular arc protrusion matching the circular arc groove. In the unfolding process, the first supporting part 11 is contacted with the second supporting part 21, and the upper plate and the lower plate are guided to be aligned accurately through the matching of the circular arc-shaped convex blocks and the circular arc-shaped grooves. In addition, the first mounting block 1 and the second mounting block 2 are connected by adopting the connecting body 3 supported by the elastic material, and the connecting piece damage caused by hard connection of the upper plate and the lower plate is avoided by utilizing the deformability of the elastic material. Meanwhile, the connecting body 3 connects the first mounting block 1 and the second mounting block 2, and the connecting body 3 provides opposite traction force for the first mounting block 1 and the second mounting block 2, so that the first supporting portion 11 acts on the second supporting portion 21. In addition, when bending, the upper plate and the lower plate are guided to fold by the traction force of the connector 3.
In one embodiment, as shown in fig. 1 to 6, the first supporting portion 11 and the second supporting portion 21 are hollow structures. The light-weight part has the function of light weight, and meanwhile, the material cost of the product is reduced.
In an embodiment, as shown in fig. 1 to 6, a first clamping groove 12 is formed on the first mounting block 1, a second clamping groove 22 is formed on the second mounting block 2, and the upper end and the lower end of the connector 3 are respectively clamped and fixed with the first clamping groove 12 and the second clamping groove 22.
In the above embodiment, as shown in fig. 1 to 6, the two sides of the openings of the first clamping groove 12 and the second clamping groove 22 are provided with the clamping strips 4 in a protruding manner, and the corresponding positions of the connecting body 3 are provided with the matched third clamping grooves 31.
