[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0021] like Figure 1-4As shown, this utility model provides a technical solution: a polyurethane foam structure for cushioning support, including a fixing plate 1 and a fixing plate 2. A rubber plate 101 is fixedly connected to the bottom end of the fixing plate 1, and a rubber plate 201 is fixedly connected to the top end of the fixing plate 2. Both the top end of the fixing plate 1 and the bottom end of the fixing plate 2 are provided with sliding grooves 203. Polyurethane foam 3 is slidably connected within the sliding groove 203 at the top end of the fixing plate 1, and polyurethane foam 4 is slidably connected within the sliding groove 203 at the bottom end of the fixing plate 2. Through the arrangement of the rubber plates 101 and 201, the bottom end of the polyurethane foam 3 and the top end of the polyurethane foam 4 can be cushioned and supported, preventing the polyurethane foam 3 from collapsing under the weight of the item and preventing the polyurethane foam 4 from being damaged or collapsed due to external pressure. This effectively protects the item within the groove 401, improves the cushioning support effect, and makes the item less prone to damage during transportation.
[0022] Furthermore, baffles 202 are fixedly connected to the top of fixed plate 1 and the bottom of fixed plate 2. Grooves 401 are provided at the top of polyurethane foam 3 and the bottom of polyurethane foam 4. A slot plate 5 is fixedly connected to the top of the baffle 202 at the top of fixed plate 1, and an insert plate 501 is fixedly connected to the bottom of the baffle 202 at the bottom of fixed plate 2. The insert plate 501 is inserted into the slot plate 5. A telescopic component 7 is provided on the side of fixed plate 1, and limiting components 8 are provided on both the left and right sides of the telescopic component 7. A limiting bracket 6 is fixedly connected to the side of fixed plate 2. By sliding polyurethane foam 3 and polyurethane foam 4 into the groove 203 at the top of fixed plate 1 and fixed plate 2 respectively, The baffle 202 in the bottom groove 203 facilitates the blocking and limiting of polyurethane foam 3 and polyurethane foam 4. At this time, the installation of polyurethane foam 3 and polyurethane foam 4 can be completed, and it is also convenient to replace polyurethane foam 3 and polyurethane foam 4 later. Then, by inserting the insert plate 501 into the slot plate 5, the telescopic component 7 is pulled to fix the limiting component 8 and the limiting frame 6, thereby completing the fixation between polyurethane foam 3 and polyurethane foam 4, so that the item is fixed in the groove 401. With the cooperation of the telescopic component 7 and the limiting frame 6, the item, polyurethane foam 3 and polyurethane foam 4 will not move or fall off between the fixing plate 1 and the fixing plate 2.
[0023] As one implementation method in this embodiment, such as Figure 1 , Figure 3 and Figure 4As shown, the telescopic assembly 7 includes a fixed frame, which is fixedly connected to the side end of the fixed plate 1. An outer plate 701 is rotatably disposed between the inner sides of the fixed frame. An inner plate 702 is inserted into the inner plate 701. A circular groove 703 is formed inside the inner plate 702. A circular rod 704 is fixedly connected to the bottom end of the inner plate 701. The circular rod 704 is inserted from the bottom end of the inner plate 702 into the circular groove 703. A circular plate 705 is fixedly connected to the top end of the circular rod 704. The outer end is fitted with a spring 706, and the top of the inner plate 702 has two sets of mounting grooves 7021. Each limiting component 8 is located in each mounting groove 7021. When the inner plate 702 is pulled, the inner plate 702 moves upward. The bottom end of the circular groove 703 cooperates with the circular plate 705 to press against the spring 706 and retract. At this time, when the inner plate 702 and the limiting component 8 are close to the limiting frame 6, the setting of the limiting component 8 facilitates the fixation between them and the limiting frame 6.
[0024] As one implementation method in this embodiment, such as Figure 2 and Figure 4 As shown, the limiting assembly 8 includes a second spring 801, which is fixedly connected to the inner side of the mounting groove 7021. A rectangular plate 802 is fixedly connected to the side of the second spring 801, and an insert 803 is fixedly connected to the side of the rectangular plate 802. The insert 803 is inserted into the outer end of the inner plate 702. The left and right sides of the limiting frame 6 are each provided with a slot 601, which is adapted to the insert 803. Since the top of each insert 803 is sloped, when the inner plate 702 moves towards the inner side of the limiting frame 6, the bottom of the limiting frame 6 presses against each insert 803. When the mounting slot 7021 moves inside, the rectangular plate 802 retracts by pressing against the second spring 801. When the side end of the insert block 803 is flush with the side end of the inner plate 702, the inner plate 702 can enter the limiting frame 6. When the insert block 803 passes through the insertion port 601, the second spring 801 pushes against the rectangular plate 802 and causes the insert block 803 to rebound, thus placing the insert block 803 inside the insertion port 601. This fixes the inner plate 702 to the limiting frame 6, thereby fixing the item between the first polyurethane foam 3 and the second polyurethane foam 4, facilitating cushioning support and transportation of the item.
[0025] Working principle: The rubber plate 101 and rubber plate 201 provide cushioning support for the bottom of polyurethane foam 3 and the top of polyurethane foam 4, improving the support stability of polyurethane foam 3 and polyurethane foam 4. This prevents polyurethane foam 3 from collapsing due to the weight of the item and polyurethane foam 4 from being damaged or collapsed due to external pressure. As a result, the items inside the slot 401 are well protected, and the cushioning support effect is improved, making the items less prone to damage during transportation.
[0026] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
