DETAILED DESCRIPTION

[0021] In order to more clearly illustrate the overall concept of the utility model, a detailed description is given below in the form of examples in conjunction with the accompanying drawings.

[0022] The examples are as follows:

[0023] The utility model provides Figure 1-5 A conference and exhibition service trolley shown in the figure comprises a trolley body 1, a limiting mechanism 2 respectively installed on the top of the trolley body 1, and an internal supporting mechanism 6;

[0024] The limiting mechanism 2 includes grooves 201 provided on both sides of the top of the cart body 1, the bottoms of the inner walls of the two grooves 201 are provided with first slide grooves 202, the inner walls of the two first slide grooves 202 are slidably provided with sliders 203, the tops of the two sliders 203 are fixed with limiting shafts 204, the outer walls of the two limiting shafts 204 are sleeved with limiting clamping strips 205, the tops of the two limiting clamping strips 205 are provided with connecting grooves 206, the inner walls of the two connecting grooves 206 are interspersed with fixing bolts 207, and the outer walls of one end of the two fixing bolts 207 pass through the inner walls of the two connecting grooves 206 and are threadedly connected to the inner walls of one side of the two limiting shafts 204, respectively. A rubber pad 208 is fixedly provided at one end of one side of the two limit clamping strips 205, and an electric telescopic rod 209 is fixedly provided at one side of the inner wall of the two first slide grooves 202. When the two limit clamping strips 205 slide on the limit shaft 204, the limit shaft 204 is limited by the inner wall of the limit clamping strip 205 so that it cannot be separated. At the same time, the upper and lower ends of the limit shaft 204 are both cylindrical, so that the limit clamping strip 205 can not only slide but also rotate thereon, which is convenient for the limit clamping strip 205 to rotate from the groove 201 so that it forms a certain angle with the cart body 1 to clamp the product. The rubber pad 208 on one side of the limit clamping strip 205 contacts the product to prevent the product from being worn.

[0025] Furthermore, the output ends of the two electric telescopic rods 209 are fixedly connected to one side of the two sliders 203 , respectively, and second slide grooves 3 are provided on both sides of the inner wall of the cart body 1 .

[0026] A first support plate 4 is slidably provided between the inner walls of the two second chutes 3, a second support plate 5 is hingedly provided on one side of the two first support plates 4, and the outer walls at both ends of the second support plate 5 are slidably connected to the inner walls of the two second chutes 3 respectively, the first support plate 4 and the second support plate 5 are hingedly connected to each other, when sliding out, the second support plate 5 rotates and falls to contact the ground, in an inclined state, which is convenient for loading and unloading exhibition products;

[0027] Furthermore, the supporting mechanism 6 includes limiting slots 601 provided at both ends of the bottom of the cart body 1 , and limiting blocks 602 are fixedly provided at both ends of the inner walls of the two limiting slots 601 .

[0028] The inner walls of the two limiting slots 601 are located on one side of the two limiting blocks 602, and support frames 603 are slidably provided. Rollers 604 are rotatably provided at the tops of the four support frames 603. A handle 7 is fixedly provided on one side of the outer wall of the cart body 1. When the first support plate 4 and the second support plate 5 slide in the second slide groove 3, the rollers 604 on the support frames 603 just contact their bottoms to support them, and rolling at the bottoms of the first support plates 4 and the second support plates 5 facilitates the adjustment of the position of the support frames 603, making its support more stable, and preventing them from escaping from the limiting slots 601 under the limiting position of the limiting blocks 602.

[0029] Working principle: When using the conference and exhibition service cart in this design, the product is supported by the first support plate 4 and the second support plate 5, and then the fixing bolt 207 is loosened so that the limiting card strip 205 can slide and rotate on the limiting shaft 204, and then slide it to the outside of the cart body 1, and rotate it ninety degrees to keep it vertical with the cart body 1, and then slide the limiting card strip 205 on the limiting shaft 204 to the inside of the cart body 1 so that its end with the rubber pad 208 is located at both ends of the product, and tighten the fixing bolt 207 to fix it, and at the same time start the electric telescopic rod 209 to slide with the slider 203 in the first slide groove 202, so that the limiting card strip 205 is stuck on both sides of the product to block and limit it. When it is not used later, it can be stored in the groove 201, so that the limiting mechanism 2 does not occupy external space, which is convenient for storage. The structure 2 is also not easy to loosen and shift, which improves stability. When loading and unloading products, the first support plate 4 and the second support plate 5 are slid out of the second slide groove 3. Since the second support plate 5 is hinged on the first support plate 4, during the movement, the two support frames 603 supported at the bottom of the second support plate 5 are blocked by the limit block 602, so that they cannot move together with it, thereby causing the second support plate 5 to lose support and tilt down, which is convenient for unloading. At this time, the support frame 603 originally supported at the bottom of the second support plate 5 is supported at the bottom of the first support plate 4, and the support frame 603 originally supported at the bottom of the first support plate 4 is also limited by the limit block 602 so that it will not continue to move. After loading the products later, the second support plate 5 is stored in the second slide groove 3. As the roller 604 rolls with it, the four support frames 603 can be supported at the bottom of the first support plate 4 and the second support plate 5 respectively, which is very convenient to use.
