TECHNICAL FIELD
[0001] The utility model relates to foaming box technical field especially relates to a polyisocyanate foaming box. BACKGROUND
[0002] In the current packaging and transportation field, the functional requirements of various box bodies are increasingly diversified.
[0003] The traditional polyisocyanate foaming box has certain limitations in actual use. On the one hand, the internal space is usually of fixed size, which is difficult to flexibly adjust according to the actual size of the loaded articles, resulting in space waste or inability to accommodate when facing different volume articles, thereby reducing the use efficiency of the foaming box. On the other hand, the existing foaming box cover fixing method is relatively single, mostly relying on simple buckling or binding, which is easy to accidentally open due to bumping, vibration and other factors during transportation, and cannot ensure the sealing and stability of the articles in the box, causing great trouble for the transportation of some articles with high environmental requirements.
[0004] Therefore, we propose a polyisocyanate foaming box. CONTENT OF THE UTILITY MODEL
[0005] The main purpose of the utility model is to provide a polyisocyanate foaming box, in order to prevent the problem of space waste or inability to accommodate articles caused by the inability to flexibly adjust the internal space, and the problem of affecting the sealing and stability caused by the accidental opening of the box cover during transportation, thereby improving the use efficiency of the foaming box and better protecting the safety of the articles in the box, which can effectively solve the problems in the background art.
[0006] To achieve the above purpose, the technical scheme adopted by the utility model is as follows:
[0007] A polyisocyanate foaming box, comprising a lower box body, an inner box body and an upper box body, the inner box body is arranged on the upper end face of the lower box body, and the lower box body and the inner box body are of an integral molding structure, the lower box body is located directly below the upper box body, and the upper box body is slidingly arranged outside the inner box body, vertical support frames are arranged on the outer walls of both ends of the lower box body, the upper end faces of the support frames are fixedly connected with connecting plates, vertical moving frames slidingly matched with the connecting plates are arranged on the outer walls of both ends of the upper box body, a plurality of equidistant limiting grooves are radially arranged on the outer wall of one side of the connecting plate, a recess is radially arranged on the inner wall of one side of the moving frame, a limiting ball capable of being inserted into the limiting groove is arranged in the recess, and one end of the limiting ball is connected with the moving frame through an axially arranged spring.
[0008] Horizontal plates are arranged on the upper parts of the outer walls of both sides of the box body, first sliding grooves are formed in the two horizontal plates, a limiting frame is arranged outside the box cover, the bottom end of the limiting frame penetrates through the first sliding groove and is threadedly connected with an adjusting bolt.
[0009] By adopting the above technical solution, the upper and lower boxes are fixed in relative position through the cooperation of the movable frame and the connecting plate. When the upper box is pushed upward, the movable frame slides upward along the connecting plate. The limiting ball in the groove inside the movable frame will have outward pressure under the action of the spring. When it moves to the appropriate position, the limiting ball will be inserted into the corresponding limiting groove on the connecting plate under the action of the spring, thereby fixing the upper box at a certain height. In this way, the internal space of the foam box can be adjusted as needed.
[0010] When it is necessary to close the lid, align the lid with the opening of the upper box, and then push the two moving frames to slide horizontally in the same direction on the first slide. As the moving frames slide, the limiting frame is gradually constrained between the two moving frames. Finally, tighten the adjusting bolt to limit the lid. At this time, the lid is firmly fixed in the closed position to prevent the lid from opening accidentally and to ensure the sealing and stability of the foam box.
[0011] When it is necessary to open the lid, the operation is reversed. First, loosen the adjusting bolt, and then push the two moving frames to slide horizontally in opposite directions on the first slide groove. As the distance between the moving frames increases, the limiting frame is no longer constrained by the moving frames. At this time, the restriction on the lid is released, and the lid can be lifted freely to realize the opening operation of the foam box, which is convenient for placing or taking out items into the box.
[0012] Furthermore, a second sliding groove is provided inside the upper housing, and the second sliding groove is slidably connected to the inner housing.
[0013] By adopting the above technical solution, when it is necessary to change the relative position of the inner box and the upper box, a pushing or pulling force can be applied to the inner box along the direction of the second slide. The second slide is like a specific moving track planned for the inner box, ensuring that the inner box remains stable during the sliding process and will not deviate or shake.
[0014] Furthermore, the side walls of the inner casing are provided with sealing gaskets.
[0015] By adopting the above technical solution, when the foam box is in use, whether the upper box and the inner box are slidably fitted together via the second sliding groove, or the lower box and the inner box are fitted together as an integral structure, the sealing gasket is always tightly fitted to the box components in contact with it. During transportation or storage, the sealing gasket can prevent dust, moisture and other impurities from entering the inner box, thus protecting the items inside the box, maintaining the cleanliness and dryness of the environment inside the box, and extending the shelf life and service life of the items inside the box.
[0016] Furthermore, handles are provided on the middle of both sides of the upper housing.
[0017] By adopting the above technical solution, the handles set in the middle of both sides of the upper box greatly improve the convenience of operating the foam box. When it is necessary to move the foam box, the user can easily hold the handles on both sides with both hands. The handles are designed in the middle of both sides of the box, which is ergonomic and allows the user to maintain balance when applying force, reducing the risk of the box tilting or falling due to uneven force.
[0018] During handling, the handle provides users with a stable grip point, allowing them to exert force more efficiently to lift and move the foam box to a designated location. For example, when moving the foam box from one work area to another, users can easily control the direction and force of the box's movement using the handle. In addition, when adjusting the relative position of the upper and lower boxes, such as sliding the upper box upwards along the inner box to expand the internal space, the handle can also serve as a point of leverage, making it easier for users to push the upper box and making the operation easier and smoother.
[0019] Furthermore, casters are provided at the four corners of the bottom of the lower housing.
[0020] By adopting the above technical solution, the moving wheels play a key role when the entire foaming box needs to be moved. Since the moving wheels are installed at the four corners of the bottom of the box, this distribution method can evenly bear the weight of the box and ensure that the box remains stable during the movement.
[0021] In practice, users only need to apply a small pushing force to the foam box, and the moving wheels will roll around its axis. The rolling friction is much smaller than the sliding friction generated directly between the box and the ground, so the foam box can be easily moved on the ground. For example, adjusting the placement of the foam box in the workshop or moving it from the warehouse to the production area, even a heavy foam box can be moved relatively easily by one person with the help of the moving wheels. Moreover, the four moving wheels allow the foam box to turn flexibly. By controlling the direction of the pushing force, the movement trajectory of the foam box can be changed to adapt to different spatial layouts and handling needs.
[0022] Compared with the prior art, the present invention has the following beneficial effects:
[0023] (1) This utility model discloses a polyisocyanurate foam box. The upper and lower boxes are connected by a unique movable frame and connecting plate structure, which allows for easy fixing and adjustment of their relative positions. When the upper box is pushed upward, the movable frame slides smoothly along the connecting plate. The limiting ball in the groove maintains outward pressure under the action of the spring. At the moment it reaches the appropriate position, the limiting ball accurately engages with the corresponding limiting groove on the connecting plate, thereby firmly fixing the upper box at the required height. This design allows the internal space of the foam box to be changed at will according to the actual size of the loaded items, greatly improving the adaptability of the foam box to different items, avoiding the problem of wasted or insufficient space, and significantly improving the efficiency of the foam box.
[0024] (2) This utility model relates to a polyisocyanurate foam box. Regarding the lid fixing, a horizontal plate and a first sliding groove are installed on the upper part of the outer walls on both sides of the box body. Combined with the use of a limiting bracket and adjusting bolts, reliable lid fixing is achieved. When closing the lid, simply align the lid with the opening of the upper box body, push the two moving brackets to slide in the same direction within the first sliding groove, and the limiting bracket will be precisely constrained between the two moving brackets. Finally, tighten the adjusting bolts, and the lid will be firmly fixed in the closed position, effectively preventing accidental opening due to vibration or other factors during transportation, ensuring the sealing and stability of the foam box's interior. When opening the lid, the operation is reversed: first loosen the adjusting bolts, then push the moving brackets to slide in the opposite direction, releasing the limiting bracket constraint, and the lid can be freely lifted. The entire operation process is simple and convenient, ensuring both the reliability of the lid fixing and ease of use, providing great convenience for users. Attached Figure Description

Detailed Implementation
[0030] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0031] To prevent issues such as wasted space or insufficient room for items due to inflexible internal space adjustment, and to address the problem of accidental opening of the lid during transportation affecting sealing and stability, thereby improving the efficiency of foam boxes and better ensuring the safety of the items inside, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a polyisocyanurate foaming box includes a lower box body 1, an inner box body 2, and an upper box body 3. The inner box body 2 is disposed on the upper end face of the lower box body 1, and the lower box body 1 and the inner box body 2 are integrally formed. The lower box body 1 is located directly below the upper box body 3, and the upper box body 3 is slidably disposed outside the inner box body 2. Support frames 5 are vertically disposed on both ends of the outer wall of the lower box body 1. A connecting plate 6 is fixedly connected to the upper end face of the support frame 5. Movable frames 7 that slide with the connecting plate 6 are vertically disposed on both ends of the outer wall of the upper box body 3. A plurality of equally spaced limiting grooves 8 are radially disposed on one side of the outer wall of the connecting plate 6. A groove 9 is radially disposed on one side of the inner wall of the movable frame 7. A limiting ball 10 that can be inserted into the limiting groove 8 is disposed in the groove 9. One end of the limiting ball 10 is connected to the movable frame 7 via an axially disposed spring 11.
[0032] Both sides of the outer wall of the box body 3 are provided with horizontal plates 12, and each of the two horizontal plates 12 is provided with a first sliding groove 13. The box cover 4 is provided with a limit frame 14 on the outside. The bottom end of the limit frame 14 passes through the first sliding groove 13 and is threadedly connected with an adjusting bolt 15.
[0033] In use, the upper box 3 and the lower box 1 are fixed in relative position through the cooperation of the movable frame 7 and the connecting plate 6. When the upper box 3 is pushed upward, the movable frame 7 slides upward along the connecting plate 6. The limiting ball 10 in the groove 9 inside the movable frame 7 will have outward pressure under the action of the spring 11. When it moves to the appropriate position, the limiting ball 10 will be inserted into the corresponding limiting groove 8 on the connecting plate 6 under the elastic force of the spring 11, thereby fixing the upper box 3 at a certain height position. In this way, the internal space of the foam box can be adjusted as needed.
[0034] When it is necessary to close the lid 4, align the lid 4 with the opening of the upper box 3, and then push the two movable frames 7 to slide horizontally in the same direction on the first slide groove 13. As the movable frames 7 slide, the limiting frame 14 is gradually constrained between the two movable frames 7. Finally, tighten the adjusting bolt 15 to limit the lid 4. At this time, the lid 4 is firmly fixed in the closed position to prevent the lid 4 from opening accidentally and to ensure the sealing and stability of the foam box.
[0035] When it is necessary to open the lid 4, the operation is reversed. First, loosen the adjusting bolt 15, and then push the two moving frames 7 to slide horizontally in opposite directions on the first slide groove 13. As the distance between the moving frames 7 increases, the limiting frame 14 is no longer constrained by the moving frames 7. At this time, the restriction on the lid 4 is released, and the lid 4 can be lifted freely to realize the opening operation of the foam box, which is convenient for placing or taking out items into the box.
[0036] For example, such as Figure 4 As shown, the present invention also includes a second sliding groove 16 provided inside the upper housing 3, the second sliding groove 16 being slidably connected to the inner housing 2.
[0037] When in use, if it is necessary to change the relative position of the inner box 2 and the upper box 3, a pushing or pulling force can be applied to the inner box 2 along the direction of the second slide 16. The second slide 16 is like a specific moving track planned for the inner box 2, ensuring that the inner box 2 remains stable during the sliding process and will not deviate or shake.
[0038] For example, such as Figure 4 As shown, the present invention also includes a sealing gasket 17 provided on the side wall of the inner box 2.
[0039] When the foam box is in use, whether the upper box body 3 and the inner box body 2 are slidably engaged through the second sliding groove 16, or the lower box body 1 and the inner box body 2 are integrated, the sealing gasket 17 always fits tightly against the box parts in contact with it. During transportation or storage, the sealing gasket 17 can prevent dust, moisture and other impurities from entering the inner box body 2, thus protecting the items inside the box, maintaining the cleanliness and dryness of the environment inside the box, and extending the shelf life and service life of the items inside the box.
[0040] For example, such as Figure 1 As shown, the present invention also includes handles 18 provided on the middle of both sides of the upper box 3.
[0041] When in use, the handles 18 located in the middle of both sides of the upper box 3 greatly improve the ease of operation of the foam box. When it is necessary to move the foam box, the user can easily hold the handles 18 on both sides with both hands. The position of the handles 18 is designed in the middle of both sides of the box, which is ergonomic and allows the user to maintain balance when applying force, reducing the risk of the box tilting or falling due to uneven force.
[0042] During handling, the handle 18 provides users with a stable gripping point, allowing them to exert force more efficiently to lift and move the foam box to a designated location. For example, when moving the foam box from one work area to another, users can easily control the direction and force of the box's movement through the handle 18. In addition, when adjusting the relative position of the upper box 3 and the lower box 1, such as sliding the upper box 3 upward along the inner box 2 to expand the internal space, the handle 18 can also serve as a point of leverage, making it easier for users to apply force to push the upper box 3, making the operation easier and smoother.
[0043] For example, such as Figure 1 As shown, the present invention also includes casters 19 at the four corners of the bottom of the lower housing 1.
[0044] When in use, the casters 19 play a key role when the entire foaming box needs to be moved. Since the casters are installed at the four corners of the bottom of the box, this distribution can evenly bear the weight of the box and ensure that the box remains stable during the movement.
[0045] In actual operation, the user only needs to apply a small pushing force to the foam box, and the moving wheel 19 will roll around its axis. The rolling friction is much smaller than the sliding friction generated directly between the box and the ground, so the foam box can be easily moved on the ground. For example, adjusting the placement of the foam box in the workshop or moving it from the warehouse to the production area, with the help of the moving wheel 19, even a relatively heavy foam box can be moved relatively easily by a single person. Moreover, the setting of four moving wheels 19 allows the foam box to turn flexibly. By controlling the direction of the pushing force, the movement trajectory of the foam box can be changed to adapt to different spatial layouts and handling needs.
[0046] It should be noted that this utility model is a polyisocyanurate foam box. Hold the handles 18 in the middle of both sides of the upper box 3 with both hands and push the upper box 3 upward. At this time, the movable frame 7 on the outer wall of both ends of the upper box 3 slides upward along the connecting plate 6 on the upper end face of the support frame 5. The limiting ball 10 in the groove 9 inside the movable frame 7 is pressed outward under the action of the spring 11. When it moves to a suitable height, the limiting ball 10 is inserted into the corresponding limiting groove 8 on the connecting plate 6, fixing the upper box 3 and completing the adjustment of the internal space size.
[0047] When it is necessary to close the lid, place the lid 4 with the opening of the upper box 3, push the two movable frames 7 to slide horizontally in the same direction on the first slide groove 13 of the horizontal plate 12, so that the limit frame 14 is constrained between the two movable frames 7, tighten the adjusting bolt 15, fix the lid 4, and ensure that it is in the closed state.
[0048] When it is necessary to open the box cover, first loosen the adjusting bolt 15, push the two moving frames 7 to slide horizontally in opposite directions on the first slide groove 13, increase the distance between the moving frames 7, and when the limiting frame 14 is no longer constrained by the moving frames 7, the box cover 4 can be lifted freely.
[0049] To move the entire foaming box, apply a small pushing force to the box. The four corners of the bottom of the lower box 1 will roll around the axis, pushing the foaming box to move on the ground. By controlling the direction of the pushing force, flexible turning can be achieved to adapt to different spatial layouts.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
