Description

Technical Field

[0001] This utility model relates to the field of folding handcart technology, specifically to a folding handcart pad structure. Background Technology

[0002] When camping outdoors, folding trolleys are often used to collect camping supplies in a centralized manner for easy carrying. To ensure that the items are placed stably at the bottom of the trolley, a mat needs to be laid at the bottom of the trolley.

[0003] The existing folding trolley floor mainly consists of multiple support plates and connecting hinges installed between adjacent support plates. Although the floor can stably place items at the bottom of the trolley after unfolding, the lack of effective restraint between adjacent support plates makes it easy for the floor to bulge due to relative rotation between the two support plates during use. This results in an uneven bottom of the trolley, which not only affects the stable placement of items but also reduces the utilization rate of the trolley's internal space. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] like Figures 1-3 As shown, a trolley pad structure in this embodiment includes individual support plates 1, with no fewer than five individual support plates 1. Connecting hinges 2 are installed between adjacent individual support plates 1 in a staggered manner. Two limiting components 3 are symmetrically installed between two adjacent individual support plates 1. Each limiting component 3 includes a limiting groove 301, a boss 302, a linkage plate 303, a sleeve rod 304, a pull ring 305, a sliding column 306, a rotating block 307, a spring 308, and a limiting groove 309. After each individual support plate 1 is opened, the first thing to do is to use the pull ring 305. Under the action of 5, the linkage plate 303 is pulled outward relative to the corresponding single support plate 1. At this time, the spring 308 is in a stretched state. Then, the linkage plate 303 is rotated 180° to ensure that the boss 302 is aligned with the limiting groove 301. Then, simply release the pull ring 305, and the sliding column 306 will be reset under the action of the spring 308. When the sliding column 306 is reset, it will insert the boss 302 into the limiting groove 301, so that the two adjacent single support plates 1 are reliably limited under the action of the linkage plate 303, the boss 302 and the limiting groove 301.

[0024] like Figures 1-3 As shown, in this embodiment, the sleeve rod 304 is mounted on a single support plate 1, and the spring 308 is installed inside the sleeve rod 304. The sleeve rod 304 is mainly used to ensure the stable sliding of the sliding column 306 and to provide a mounting base for the spring 308. A rotating block 307 is connected to the end of the spring 308 facing away from the sleeve rod 304, and a sliding column 306 is connected to the end of the rotating block 307 facing away from the spring 308. The spring 308 is mainly used to realize the automatic reset of the sliding column 306 after sliding. The linkage plate 303 is installed on the sliding column 306 facing away from the rotating block 307. At the end, the pull ring 305 is installed on the outer wall of the linkage plate 303, directly opposite the slide column 306. The boss 302 is reserved on the linkage plate 303 on the side opposite to the slide column 306. The first limiting groove 301 is opened on one single support plate 1, and the second limiting groove 309 is opened on another single support plate 1. When the two adjacent single support plates 1 are in a folded state, the boss 302 is inserted into the second limiting groove 309. At this time, the linkage plate 303 and the boss 302 are in an idle state, which can ensure convenient folding between the two adjacent single support plates 1.

[0025] like Figures 1-3As shown, in this embodiment, the dimensions of the boss 302 match the dimensions of the first limiting groove 301 and the second limiting groove 309. The first limiting groove 301 and the second limiting groove 309 are symmetrically distributed relative to the sliding column 306. The boss 302 and the first limiting groove 301 cooperate to achieve reliable positioning between two adjacent single support plates 1. The boss 302 and the second limiting groove 309 cooperate to ensure convenient folding between two adjacent single support plates 1. One end of the spring 308 is inserted into the sleeve rod 304, and the other end of the spring 308 is inserted into the rotating block 307. The rotating block 307 is rotatably connected to the sliding column 306. The sliding column 306 and the sleeve rod 304 are slidably engaged. The rotating block 307 can ensure that the sliding column 306 can rotate relative to the sleeve rod 304 while being pulled, avoiding the disadvantage of the spring 308 torturing and failing when the sliding column 306 rotates.

[0026] The specific implementation process of this embodiment is as follows: In use, firstly, each individual support plate 1 is opened, and then, under the action of the pull ring 305, the linkage plate 303 is pulled outward relative to the corresponding individual support plate 1. At this time, the spring 308 is in a stretched state. Then, the linkage plate 303 is rotated 180° to ensure that the boss 302 is aligned with the limiting groove 301. Then, simply release the pull ring 305, and the sliding column 306 will be reset under the action of the spring 308. When the sliding column 306 is reset, it will insert the boss 302 into the limiting groove 301, so that the two adjacent individual support plates 1 are reliably limited under the action of the linkage plate 303, the boss 302 and the limiting groove 301, avoiding the disadvantage of relative rotation and bulging of the two adjacent individual support plates 1 after the pad is opened, making the items in the trolley more stable, and at the same time making full use of the internal space of the trolley.
