Description

Technical Field

[0001] This utility model relates to the field of pearl cotton box technology, specifically to a pearl cotton box that is easy to transport. Background Technology

[0002] Polyethylene foam, also known as EPE pearl cotton, is a non-crosslinked closed-cell structure and a new type of environmentally friendly packaging material. It is composed of countless independent air bubbles created through the physical foaming of low-density polyethylene resin. This overcomes the shortcomings of ordinary foam, such as fragility, deformation, and poor resilience. It possesses numerous advantages, including water and moisture resistance, shock absorption, sound insulation, heat insulation, excellent plasticity, high toughness, recyclability, environmental friendliness, and strong impact resistance. It also exhibits excellent chemical resistance, making it an ideal substitute for traditional packaging materials.

[0003] A search revealed that Chinese patent application CN219155042U discloses a pearl cotton box for valve bodies with puncture-resistant properties. A first buffer protrusion secures a first spacer inside a first pearl cotton box to prevent it from falling out, and a second buffer protrusion secures a second spacer inside a second pearl cotton box. Spacers one and two prevent burrs from the valve body edge from puncturing the pearl cotton box. Simultaneously, the first and second buffer protrusions cushion the valve body, protecting it during transportation.

[0004] However, the following technical problems still exist when implementing the above technical solution: During transportation, it is necessary to fix it by wrapping it with tape. However, during transportation, the instrument will shake with the movement of the vehicle body, which will exert a pushing force on the lid. Over time, the tape will deform, causing the connection between the lid and the box to loosen. This may cause the lid and the box to separate and make it impossible to continue to seal and fix the instrument.

[0005] Therefore, providing a convenient pearl cotton box that can effectively prevent accidental opening during transportation and avoid items falling, being lost, or being damaged is a problem that this utility model urgently needs to solve. Utility Model Content

[0010] Preferably, a toggle block is fixedly provided on the plug-in plate.

[0011] Preferably, the fitting cavity is provided with a compression buffer mechanism for compressing and buffering items placed at different heights within the placement cavity.

[0012] Preferably, the compression buffer mechanism includes: multiple sets of mounting slots spaced apart in the fitting cavity, each set of mounting slots is fixedly provided with a sliding rod, the movable end of the sliding rod is vertically downward and the top end is fixedly provided with a compression plate that contacts the surface of the item placed in the placement cavity, and the sliding rod is fitted with a damping spring at both ends that abut against the inner top wall of the fitting cavity and the side wall of the compression plate, respectively.

[0026] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0027] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0028] Reference Figures 1-6 As shown, a transportable pearl cotton box includes: a box body 100 and a top cover 101 hinged to the box body 100. The box body 100 has a placement cavity 104, and the top cover 101 has a fitting cavity 105 that mates with the placement cavity 104. The box body 100 is provided with a locking mechanism 200 that locks the top cover 101 during transport to prevent items inside the box body from falling out.

[0029] The locking mechanism 200 includes: a locking member fixedly installed on the box body 100, and a plug rod 201 for cooperating with the locking member fixedly provided on the top cover 101.

[0030] In use, open the top cover 101 hinged to the box body 100, place the item to be transported into the placement cavity 104 of the box body 100, and utilize the cushioning properties of the pearl cotton to provide initial protection for the item. Close the top cover 101 onto the box body 100. At this time, the fitting cavity 105 on the top cover 101 and the placement cavity 104 of the box body 100 correspond to each other to form a closed space. Subsequently, insert the insertion rod 201 on the top cover 101 into the locking member on the box body 100. Through the cooperation of the locking member and the insertion rod 201, the top cover 101 is locked onto the box body 100, completing the closure of the pearl cotton box. During transportation, the locking mechanism 200 maintains a stable connection between the top cover 101 and the box body 100, preventing the top cover 101 from opening due to external forces such as bumps and vibrations, ensuring that the item inside the box body 100 will not fall out, and the pearl cotton material continuously provides cushioning protection for the item.

[0031] Reference Figures 2-5 As shown, the locking component includes: a fixing block 202 fixedly installed on the housing 100; a plug plate 205 rotatably mounted on the fixing block 202 via a rotating shaft 203; a torsion spring 204 fixedly sleeved on the rotating shaft 203 and abutting against the side wall of the plug plate 205; an clearance groove 207 for the plug plate 205 to rotate on the fixing block 202; a plug groove 208 for the plug rod 201 to be inserted on the fixing block 202; a limiting block 209 fixedly mounted at one end of the plug plate 205 for use with the plug rod 201; and a toggle block 206 fixedly mounted on the plug plate 205.

[0032] In the above scheme, after opening the top cover 101 and placing the item into the placement cavity 104, the top cover 101 is closed, aligning the insertion rod 201 with the insertion slot 208 on the fixing block 202. When the insertion rod 201 is inserted into the insertion slot 208, its front end presses against the limiting block 209, pushing the insertion plate 205 to rotate around the pivot 203. When the insertion rod 201 is fully inserted, the torsion spring 204 rebounds, driving the insertion plate 205 to rotate in the opposite direction, causing the limiting block 209 to engage with the groove or rear end of the insertion rod 201, achieving automatic locking. During transportation, the continuous elasticity of the torsion spring 204 ensures that the limiting block 209 fits tightly against the insertion rod 201, preventing the insertion rod 201 from coming out due to vibration or collision. When unlocking is required, the finger moves the lever 206, causing the insertion plate 205 to rotate around the pivot 203. The lever action of the lever 206 makes rotation easier, and the limiting block 209 quickly disengages from the insertion rod 201.

[0033] Reference Figure 6 As shown, the fitting cavity 105 is provided with a compression buffer mechanism 300 for compressing and buffering items placed at different heights in the placement cavity 104. The compression buffer mechanism 300 includes: multiple sets of mounting slots 301 spaced apart in the fitting cavity 105, each set of mounting slots 301 is fixedly provided with a sliding rod 302, the movable end of the sliding rod 302 is vertically downward and the top end is fixedly provided with a compression plate 303 that contacts the surface of the item placed in the placement cavity 104, and a damping spring 304 is sleeved on the sliding rod 302, with both ends abutting against the inner top wall of the fitting cavity 105 and the side wall of the compression plate 303 respectively.

[0034] In the above scheme, items of different heights are placed into the placement cavity 104 of the box 100. When the top cover 101 is closed, the compression plate 303 contacts the top of the item. As the top cover 101 closes, the item pushes the compression plate 303 to slide upward along the sliding rod 302, compressing the damping spring 304. The compression of the damping spring 304 generates elastic force, which acts in the opposite direction on the compression plate 303, making the compression plate 303 tightly adhere to the surface of the item. During transportation, when encountering vibration or impact, the damping spring 304 absorbs energy through compression and rebound, and the compression plate 303 always maintains stable compression of the item, preventing the item from shaking.

[0035] Reference Figures 1-3 As shown, the box body 100 has placement slots 102 on its mutually spaced side walls, and each set of placement slots 102 has a handle 103 rotatably mounted in it.

[0036] In the above design, the handle 103 is stored in the placement slot 102 on the side wall of the box 100. At this time, the pearl cotton box is flat, facilitating stacking and saving space. When the pearl cotton box needs to be moved, the handle 103 is manually rotated upwards from the placement slot 102 until it is horizontal, forming a handle structure for gripping. The user holds the handle 103 and applies force to lift the pearl cotton box for movement. During transport, the handle 103 maintains a stable connection with the box 100, ensuring safe handling. After transport, the handle 103 is rotated downwards to return it to the placement slot 102, restoring the pearl cotton box to its flat state for easy subsequent storage or stacking.

[0037] Reference Figures 1-3 As shown, the placement cavity 104 is provided with a buffer pad 107, and multiple sets of buffer protrusions 106 that penetrate the buffer pad 107 are fixedly arranged at intervals in the placement cavity 104.

[0038] In the above solution, the items to be transported are placed in the placement cavity 104, and the items are in direct contact with the spacer 107. The spacer 107 and the buffer protrusion 106 provide initial cushioning and support for the items. During transportation, when the pearl cotton box is subjected to external forces such as vibration and collision, the soft material of the spacer 107 absorbs part of the impact force, while the buffer protrusion 106 further disperses the external force through deformation, reducing the direct effect of external forces on the items and protecting the items in all aspects.

[0039] In summary, the pearl cotton box provided by this utility model is easy to transport. When in use, the top cover 101 hinged to the box body 100 is opened, exposing the placement cavity 104 of the box body 100. The spacers 107 and buffer protrusions 106 within the placement cavity 104 are ready to receive the items. The items to be transported are placed into the placement cavity 104, where the spacers 107 and buffer protrusions 106 provide initial cushioning and support, preventing direct collision between the items and the box body 100. If the items are of different heights, when the top cover 101 is subsequently closed, the compression buffer mechanism 300 within the fitting cavity 105 will activate, closing the top cover 101 so that the fitting cavity 105 on the top cover 101 corresponds and engages with the placement cavity 104 of the box body 100, forming a closed space. At the same time, the insertion rod 201 on the top cover 101 is inserted into the insertion slot 208 on the fixing block 202 of the box body 100. The insertion rod 201 presses against the limiting block 209 on the insertion plate 205, pushing the insertion plate 205 to rotate around the rotating shaft 203, and the torsion spring 204 is compressed. When the insertion rod 201 is fully inserted, the torsion spring 204 rebounds, causing the insertion plate 205 to rotate in the opposite direction, so that the limiting block 209 is locked into the insertion rod 201, completing the locking. During this process, if the items are of different heights, the compression plate 303 slides along the sliding rod 302, and the damping spring 304 is compressed to generate elastic force, so that the compression plate 303 fits tightly against the top of the item, achieving adaptive compression buffering. When the pearl cotton box needs to be moved, the handle 103 is rotated upward from the placement slot 102 on the side wall of the box body 100 to a horizontal position. The user holds the handle 103 to lift the pearl cotton box for movement. During transportation, the locking mechanism 200 relies on the elastic force of the torsion spring 204 and the cooperation of the limiting block 209 and the insertion rod 201. The top cover 101 is securely connected to the box body 100. The spacer 107, the buffer protrusion 106 and the compression buffer mechanism 300 work together to absorb vibration and impact, preventing items from shaking, shifting or colliding inside the box. The pearl cotton material also continuously provides cushioning protection for the items. After reaching the destination, the finger moves the lever 206 on the plug plate 205, causing the plug plate 205 to rotate around the pivot 203, overcoming the elastic force of the torsion spring 204, so that the limit block 209 disengages from the plug rod 201 and the plug rod 201 is pulled out from the plug slot 208.
