Description

Technical Field

[0001] This utility model relates to the field of plywood boxes, specifically a plywood box with waterproof properties. Background Technology

[0002] Plywood crates are a type of wooden crate made of ordinary wood boards and plywood. They are wooden crates with wood for the frame and plywood for the top. Due to their flexibility in packing, adaptability to different loads, and reusability, plywood crates are used in machinery, chemical, electronics, hardware and other fields.

[0003] According to Chinese Patent Publication No. CN212638454U, a waterproof plywood box is disclosed. This utility model has a drying chamber at the bottom of the storage cavity, and a desiccant is placed inside the drying chamber. The corrugated board and the support board are provided with several through holes. The interaction between the several through holes can prevent the local space from being closed and promote the air circulation between the layers. So when local moisture occurs, it can quickly participate in the connection between the through holes and use the desiccant to dry it, thus preventing the inside from getting damp.

[0004] Regarding the aforementioned patent content, a cavity is created inside the bottom plate, and a desiccant is placed inside the cavity to achieve a drying effect. However, since the desiccant will become saturated after absorbing moisture for a long time, it needs to be replaced every once in a while. But when replacing the desiccant, the top plate needs to be removed, and then the corrugated cardboard and support plate inside the box need to be taken out in order to remove the desiccant inside the cavity. This removal process is quite troublesome, which makes it inconvenient to replace the desiccant quickly, thus reducing the efficiency of desiccant replacement. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a waterproof plywood box to solve the technical problem of the inconvenience of quickly replacing the desiccant.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waterproof plywood box, comprising a bottom plate, side plates on all four sides of the top of the bottom plate, a pop-out assembly inside the bottom plate, the pop-out assembly including a cavity inside the bottom plate, a spring and a push rod respectively installed on one side inside the cavity, a push plate connected to one end of the spring, a drying box slidably connected inside the cavity, and multiple through holes on the top of the drying box, a sealing plate installed on one side of the bottom plate by screws, and a pressure plate extending into the cavity on one side of the sealing plate.

[0007] By adopting the above technical solution, when it is necessary to disassemble the drying box to replace the desiccant, the sealing plate can be removed first. At this time, the pressure plate will no longer press the drying box, and the spring will be stretched.

[0008] Furthermore, a plywood is installed on one side of the side panel, and a water-based transparent varnish coating is provided on one side of the plywood, and a plastic film is provided on one side of the water-based transparent varnish coating.

[0009] By adopting the above technical solution, the water-based transparent varnish coating can prevent the penetration of humid air. At the same time, by using the water-based transparent varnish coating as an adhesive, a plastic film is attached to the outermost layer, which blocks humid air from the outside during normal use, thereby improving the waterproofness of the wooden box.

[0010] Furthermore, an oil felt is provided on the other side of the side plate, and the thickness of the plastic film is 0.1 mm.

[0011] By adopting the above technical solution and installing tar paper, the goods are not only waterproof, but also absorb moisture that may be present in the goods themselves and may generate water vapor under temperature changes.

[0012] Furthermore, a top plate is installed on the top of the side plate, and a clamping plate is installed between the top plate, the side plate, and the bottom plate by fastening bolts.

[0013] By adopting the above technical solution, the stability of the connection between the top plate, side plate, and bottom plate can be improved after the card plate is installed on the top plate, side plate, and bottom plate.

[0014] Furthermore, positioning blocks are provided around the top of the base plate, and positioning grooves are provided at the bottom of the side plate, with the positioning blocks located inside the positioning grooves.

[0015] By adopting the above technical solution, the positioning block can be inserted into the positioning groove, thereby positioning the side plate.

[0016] Furthermore, the top of the base plate is provided with multiple ventilation holes, and the number of ventilation holes is the same as the number of through holes.

[0017] By adopting the above technical solution, air can enter the drying box through the vents and openings, allowing the desiccant inside the drying box to absorb moisture from the air.

[0018] Furthermore, the sealing plate is detachably connected to the base plate by screws.

[0019] By adopting the above technical solution, the sealing plate can be installed on the base plate with screws, and the sealing plate can be easily disassembled later.

[0020] Furthermore, the push plate is slidably connected to the cavity, and one side of the push plate contacts one side of the drying box.

[0021] By adopting the above technical solution, the push plate can slide inside the cavity, and when the drying box moves into the cavity, it will push the push plate to move.

[0022] Furthermore, one end of the push rod contacts the push plate, and one side of the pressure plate contacts the other side of the drying box.

[0023] By adopting the above technical solution, the push rod can prevent the push plate from moving excessively, so that the through hole on the drying box can be aligned with the vent hole.

[0024] Furthermore, the bottom of the base plate is provided with a base on both sides, and the diameter of the vent hole is larger than the diameter of the through hole.

[0025] By adopting the above technical solution, the base can support the bottom plate, preventing the bottom plate from directly contacting the ground.

[0026] In summary, the present invention has the following main advantages:

[0027] This invention features a pop-out assembly. When the dry box needs to be disassembled for desiccant replacement, the screws can be unscrewed from the sealing plate and base plate. The sealing plate can then be removed, at which point the pressure plate no longer presses against the dry box, the spring stretches, and pushes the push plate, which in turn moves the dry box out of the cavity. The dry box can then be removed for desiccant replacement. After replacement, the dry box is inserted into the cavity. Next, the pressure plate on the sealing plate is inserted into the cavity, and the sealing plate is pushed, causing the pressure plate to push the dry box out. The dry box moves by pushing the push plate and compressing the spring. When the push rod contacts the push plate, the dry box can no longer move. At this point, the through hole and the vent hole are aligned. Then, the screw is screwed into the sealing plate and the bottom plate to fix the sealing plate. This allows the dry box to be firmly inserted into the cavity without popping out. This method also makes it easier to remove the dry box and replace the desiccant without removing the side plates and multiple corrugated plates or support plates to remove and replace the desiccant, thus improving the efficiency of desiccant replacement.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] The embodiments of this utility model will be described below based on its overall structure.

[0036] Example 1:

[0037] A waterproof plywood crate, such as Figures 1-5 As shown, the box includes a base plate 1, with side plates 3 on all four sides of the top of the base plate 1. A pop-out assembly 9 is located inside the base plate 1. A plywood 7 is installed on one side of each side plate 3, with a water-based transparent varnish coating 8 on one side and a plastic film 10 on the other. The water-based transparent varnish coating 8 prevents the penetration of humid air. The plastic film 10 is then attached to the outermost layer using the water-based transparent varnish coating 8 as an adhesive, thus blocking humid air during normal use and improving the box's waterproofness. An tar paper 11 is installed on the other side of each side plate 3. The plastic film 10 is 0.1 mm thick. The tar paper 11 provides waterproofing while also quickly absorbing moisture from the goods, which may contain moisture and easily generate condensation under temperature changes. Locking bolts are installed between the top plate 4 and the side plates 3, and between the base plate 1 and the side plates 3.

[0038] Specifically, the pop-out component 9 includes a cavity 901 formed inside the base plate 1. A spring 905 and a push rod 909 are respectively installed on one side of the cavity 901. One end of the spring 905 is connected to a push plate 904. A drying box 902 is also slidably connected inside the cavity 901. The drying box 902 is filled with desiccant to absorb moisture, thereby drying the inside of the wooden box. The top of the drying box 902 has multiple through holes 903. One side of the base plate 1 is connected by screws 905. 08 is equipped with a sealing plate 907, which is detachably connected to the base plate 1 by screws 908. The sealing plate 907 can be installed on the base plate 1 by screws 908, and it is convenient to remove the sealing plate 907 later. On one side of the sealing plate 907, there is a pressure plate 906 extending into the cavity 901. When it is necessary to remove the drying box 902 to replace the desiccant, the sealing plate 907 can be removed first. At this time, the pressure plate 906 no longer presses the drying box 902, and the spring 905 will be stretched.

[0039] Specifically, the top of the base plate 1 is provided with multiple vent holes 14, and the number of vent holes 14 is the same as the number of through holes 903. The vent holes 14 and through holes 903 correspond one-to-one so that air can enter the drying box 902 through the vent holes 14 and through holes 903, allowing the desiccant in the drying box 902 to absorb moisture from the air. The push plate 904 is slidably connected to the cavity 901, and one side of the push plate 904 contacts one side of the drying box 902 so that the push plate 904 can slide inside the cavity 901, while drying... When box 902 moves into cavity 901, it pushes push plate 904 to move. One end of push rod 909 contacts push plate 904, and one side of pressure plate 906 contacts the other side of drying box 902. Push rod 909 can prevent push plate 904 from moving excessively, so that through hole 903 on drying box 902 can be aligned with vent hole 14. Base 2 is provided on both sides of bottom of bottom plate 1. The diameter of vent hole 14 is larger than the diameter of through hole 903. Base 2 can support bottom plate 1 and prevent bottom plate 1 from directly contacting the ground.

[0040] Example 2:

[0041] Based on the above embodiment 1, in order to improve the stability between the top plate 4, the side plate 3 and the bottom plate 1, the following structure will be set.

[0042] See Figure 1 , Figure 2 and Figure 5 A top plate 4 is installed on the top of the side plate 3. A clamping plate 5 is installed between the top plate 4, the side plate 3 and the bottom plate 1 by fastening bolts 6. When the clamping plate 5 is installed on the top plate 4, the side plate 3 and the bottom plate 1, the stability of the connection between the top plate 4, the side plate 3 and the bottom plate 1 can be improved.

[0043] Example 3:

[0044] Based on the above embodiment 1, in order to facilitate the installation of side plate 3, it is necessary to position side plate 3, so the following structure will be set.

[0045] See Figure 2 and Figure 4 The bottom plate 1 has positioning blocks 13 on all four sides of the top, and the side plate 3 has a positioning groove 12 at the bottom. The positioning blocks 13 are adapted to the positioning groove 12 and are located inside the positioning groove 12 so that the positioning blocks 13 can be inserted into the positioning groove 12, thereby positioning the side plate 3.

[0046] The working principle of this utility model is as follows: First, the staff can install the card plate 5 on the top plate 4, side plate 3 and bottom plate 1 with the fastening bolts 6, which can improve the stability between the top plate 4, side plate 3 and bottom plate 1. At the same time, the water-based transparent varnish coating 8 can prevent the penetration of humid air. Meanwhile, the water-based transparent varnish coating 8 is used as an adhesive, and a plastic film 10 is attached to the outermost layer, so that humid air is blocked from the outside during normal use, thereby improving the waterproofness of the wooden box. The desiccant is set inside the drying box 902 to absorb the moisture in the air and improve the moisture-proof effect inside the wooden box.

[0047] When it is necessary to disassemble the desiccant box 902 for replacement, screw 908 can be unscrewed from the sealing plate 907 and the base plate 1. Then, the sealing plate 907 can be removed. At this time, the pressure plate 906 no longer presses against the desiccant box 902, and the spring 905 will stretch, pushing the push plate 904 to move. The push plate 904 then pushes the desiccant box 902 to move, causing the desiccant box 902 to move out of the cavity 901. Then, the desiccant box 902 can be removed for replacement. The replaced desiccant box 902 is inserted into the cavity 901, and then the sealing plate 906 is removed. The pressure plate 906 on 07 is inserted into the cavity 901 and pushes the sealing plate 907, causing the pressure plate 906 to push the drying box 902 to move. The drying box 902 pushes the push plate 904 to move and squeezes the spring 905. When the top rod 909 contacts the push plate 904, the drying box 902 can no longer move. At this time, the through hole 903 and the vent hole 14 are aligned. Then, the screw 908 is screwed into the sealing plate 907 and the bottom plate 1 to fix the sealing plate 907. In this way, the drying box 902 can be firmly inserted into the cavity 901 without popping out.
