Description

Technical Field

[0001] The utility model relates to the technical field of household articles, and particularly relates to an automatic lifting disposable article packaging box. Background Art

[0002] Disposable hand wipes and disposable examination gloves are widely used in medical places such as hospitals. These products usually adopt disposable plastic packaging to ensure hygiene and convenient use. However, when the number of paper towels or gloves is small, it may be difficult to extract the paper towels or gloves, which brings inconvenience to users. The patent with the publication number CN202665410U provides an automatic paper feeding tissue box, including a box body, characterized in that: a horizontal partition is arranged inside the box body, and an elastic member is arranged between the bottom of the horizontal partition and the bottom of the box body to gradually push the horizontal partition. Specifically, the elastic member is four springs arranged at the bottom corners of the horizontal partition, and the elastic force of these springs is proportional to the deformation amount, that is, the larger the deformation amount, the greater the elastic force. Therefore, when the tissue box is full of paper towels or gloves, the deformation amount of the springs is the largest, and the corresponding elastic force is also the largest, so as to generate a large pushing force on the paper towels or gloves. As the paper towels or gloves gradually decrease, the deformation amount of the springs decreases, and the elastic force also decreases accordingly. When the number of paper towels or gloves is large, due to the large pushing force of the springs, it may be difficult to smoothly extract the paper towels or gloves. Therefore, the solution of directly pushing the paper towels or gloves by springs alone cannot fully meet the actual use requirements. Content of the Utility Model

[0003] The purpose of the utility model is to provide an automatic lifting disposable article packaging box for the deficiencies of the prior art.

[0004] The specific technical solution is as follows:

[0005] An automatic lifting disposable article packaging box, comprising:

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts fall within the scope of protection of the present utility model.

[0024] It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other.

[0025] Next, the present utility model will be further described in conjunction with the accompanying drawings and specific embodiments, but it is not a limitation of the present utility model.

[0026] An automatic lifting disposable product packaging box provided in the present utility model, referring to Figures 1 - 3 , includes:

[0027] The box body 3, which has an opening at the upper part and is used for storing disposable products; and two arc-shaped slide rails 7 are respectively arranged on both sides inside the box body 3, and the two arc-shaped slide rails 7 on the same side are distributed in a horn shape, with the smallest distance at the lower end and gradually increasing upward distance;

[0028] The lid 1, which is detachably covered at the opening of the box body 3; an extraction port 2 is provided in the middle of the lid 1 for the user to extract disposable products; and

[0029] The pushing plate 4, which is located inside the box body 3, and two pulleys 5 are respectively arranged on both sides of the pushing plate 4. The pulleys 5 are abutted against the arc-shaped slide rails 7 under the action of the elastic member 10, and the arc-shaped slide rails 7 provide an upward component force to the pulleys 5, thereby driving the pushing plate 4 to push the disposable products upward.

[0030] Referring to Figure 1, specifically, in this embodiment, the box body 3 is made of environmentally friendly materials and has sufficient strength and rigidity to support the internal structure and disposable items, such as recyclable cardboard, biodegradable plastics, or bamboo fiber materials. The two arc-shaped slide rails 7 opened on the same side are distributed in a horn shape, with the smallest distance at the lower end to ensure that the contact area between the pushing plate 4 and the slide rail is maximized when the pushing plate 4 is at the bottom, thereby providing sufficient supporting force. The upward distance gradually increases to adapt to the spatial change during the rising process of the pushing plate 4 and ensure the smooth movement of the pulley 5 along the slide rail. The lid 1 is designed to be detachable for easy replenishment of disposable items. A drawing opening 2 is provided in the middle of the lid 1 with a moderate size, which can not only ensure the convenience of the user to draw disposable items but also prevent the excessive exposure of disposable items and maintain hygiene. The pushing plate 4 is located inside the box body 3, and two pulleys 5 are provided on each side. Under the action of the elastic member 10, the pulleys 5 always abut against the arc-shaped slide rails 7 to ensure the smooth movement of the pulleys 5 along the slide rails, while providing sufficient supporting force and guidance. The elastic member 10 is fixed inside the I-beam of the pushing plate 4, and the two ends are respectively fixed at the two ends of the inner wall of the longitudinal rod 9 of the I-beam. When the disposable item is taken out, due to the reduction of the weight on the pushing plate 4, the compression force of the elastic member 10 drives the pulley 5 and the pushing plate 4 to move upward on the arc-shaped slide rail. Through the movement of the pulley 5 on the slide rail, the automatic pushing function is realized to ensure that the disposable item is always in the best drawing position. The slide rail design with a horn shape distribution ensures the stability of the pushing plate 4 during the rising process. At the same time, wear-resistant materials are selected to make the pulley 5 to reduce the friction with the slide rail and extend the service life. The design of the drawing opening 2 provided in the middle of the lid 1 facilitates the user to quickly and hygienically draw disposable items, while ensuring the cleanliness and hygiene of the remaining items in the box body 3. This automatic lifting disposable item packaging box realizes the automatic pushing of disposable items through the ingenious design of the box body 3, slide rail, pushing plate 4, and elastic member 10, which not only improves the convenience of use but also ensures the hygienic safety of the product and is applicable to the packaging and use scenarios of various disposable items.

[0031] In this device, refer to Figure 2 and Figure 3, the pushing plate 4 includes an upper plate 11, a lower plate 12 and an I-shaped frame. The upper plate 11 and the lower plate 12 form the main body of the pushing plate 4. The upper plate 11 covers the upper part of the lower plate 12 through a clamping structure. The I-shaped frame is arranged between the two plates. They jointly bear the weight of the disposable products and ensure the matching with the internal structure of the box body 3. The longitudinal rod 9 of the I-shaped frame is a telescopic rod. The elastic member 10 is fixedly arranged at both ends of the inner wall of the longitudinal rod 9 and is used to drive the telescopic movement of the longitudinal rod 9. The telescopic rod is designed to adapt to the rise and fall of the pushing plate 4. The elastic member 10 inside it is fixed at both ends and can automatically adjust according to the load change of the pushing plate 4, driving the telescopic movement of the longitudinal rod 9, so as to realize the lifting of the pushing plate 4. The middle position of the longitudinal rod 9 is fixedly placed in the middle position of the slot 13 of the lower plate 12, which can provide a more balanced force distribution, ensure the stability of the pushing plate 4 during the lifting process, and reduce the possibility of tilting or shaking; and the length setting of the slot 13 of the lower plate 12 can not only accommodate the longitudinal rod 9, but also limit the cross bar 8 in the I-shaped frame, ensuring that the cross bar 8 will not have unnecessary displacement or tilt when the longitudinal rod 9 expands and contracts, and maintaining the integrity of the structure of the pushing plate 4. The pulley 5 is installed at the outer ends of the two cross bars 8 of the I-shaped frame and cooperates with the arc-shaped slide rail 7 inside the box body 3 to ensure the smooth movement of the pushing plate 4 during the lifting process; in addition, a buffer space for the telescopic movement of the longitudinal rod 9 is reserved in advance between the upper plate 11 and the lower plate 12. The pulley 5 always abuts against the slide rail under the action of the elastic member 10 and provides an upward component force. When the disposable products are taken out and the load of the pushing plate 4 is reduced, the restoring force of the elastic member 10 drives the telescopic rod to elongate, thereby driving the entire pushing plate 4 to rise, ensuring that the disposable products are always in a convenient extraction position close to the opening of the box body 3. The pulley 5 rolls on the arc-shaped slide rail 7 of the box body 3, providing a guiding function to ensure the stable rise and fall of the pushing plate 4 and prevent tilting or jamming during the lifting process.

[0032] Specifically, referring to Figures 2 - 3, a guide rod 14 is also vertically provided inside the box body 3. The guide rod 14 is vertically arranged inside the box body 3, in the same direction as the lifting direction of the push plate 4. The length of the guide rod 14 matches the lifting range of the push plate 4 to ensure that the push plate 4 is always guided and supported during the lifting process. Usually, the guide rod 14 is made of a material with certain strength and wear resistance, such as stainless steel or aluminum alloy, to ensure its stability and durability during long-term use. The surface is smooth-treated to reduce the friction when the sliding sleeve 6 slides; sliding sleeves 6 are provided on both sides of the push plate 4. The sliding sleeves 6 are slidably sleeved on the guide rod 14 to ensure the guiding and positioning of the push plate 4 during the lifting process. The inner diameter of the sliding sleeve 6 is slightly larger than that of the guide rod 14 to allow sliding but not too large to ensure the guiding effect. Among them, the material of the sliding sleeve 6 should have good wear resistance and self-lubricity, such as using materials like Teflon or high-density polyethylene, to reduce the friction with the guide rod 14 and extend the service life. Through the cooperation of the guide rod 14 and the sliding sleeve 6, the lifting movement of the push plate 4 is more stable. Even when carrying heavy disposable items, it can remain stable, avoiding jamming or damage caused by shaking or deviation, reducing the lateral shaking and friction of the push plate 4 during the lifting process, extending the service lives of the push plate 4, the guide rod 14, and the sliding sleeve 6, and reducing the maintenance cost.

[0033] Refer to Figure 3 , the elastic member 10 is a spring, and its elastic force is proportional to the deformation amount. When the push plate 4 presses down under the weight of the disposable item, the spring is compressed, the deformation amount increases, and the elastic force increases, providing an upward supporting force. As the push plate 4 moves upward, the deformation amount of the spring decreases, which means that the elastic force of the spring also decreases accordingly. This design ensures that no matter what position the push plate 4 is in, the spring can provide sufficient supporting force to make the push plate 4 lift and lower smoothly. And the spring in this device is designed with its spring stiffness and pre-compression amount carefully to ensure that when the disposable item is taken out, the spring provides an appropriate pushing force, neither too small to cause the push plate 4 to drop nor too large to make it difficult to extract the disposable item.

[0034] Specifically, refer to Figure 2, the tangent of the lowest end of the arc-shaped slide rail 7 has the largest angle with the bottom surface, which means that when the pushing plate 4 starts to rise, the upward component force provided by the slide rail is the largest; as the pushing plate 4 continues to rise, the deformation of the elastic member 10 (such as a spring) decreases, and the upward force it provides also decreases accordingly. The angle between the tangent above the set arc-shaped slide rail 7 and the bottom surface gradually decreases. Even if the deformation of the elastic member 10 decreases, through the guiding function of the slide rail, a consistent upward force in the vertical direction can be provided to ensure the force balance during the rising process of the pushing plate 4; the angle change design of the arc-shaped slide rail 7 enables the pulley 5 to always obtain a constant upward component force during the rolling process on the slide rail. Even if the elastic force of the elastic member 10 decreases with the decrease of the deformation, through the angle adjustment of the slide rail, the force balance during the rising process of the pushing plate 4 can be maintained, realizing smooth rising. That is, after the disposable item is taken out, the pushing plate 4 can also rise smoothly and accurately to the appropriate position.

[0035] The bottom of the box body 3 is provided with an anti-slip base. The anti-slip base is made of materials with a high coefficient of friction, such as rubber or silica gel, to ensure the stability of the packaging box on a smooth surface and reduce the risk of sliding. The base is designed with concave-convex patterns or sucker type to further enhance the grip and prevent the packaging box from accidentally sliding during transportation or use, improving the stability and safety of the automatic lifting disposable item packaging box. Especially when used on an uneven or smooth surface, it ensures the stability of the packaging box and avoids accidents caused by sliding.

[0036] Specifically, the lid 1 is provided with a locking mechanism to prevent accidental opening during transportation or storage. Through mechanical buckles, magnetic adsorption or electronic locks, etc., it is ensured that the lid 1 will not accidentally open due to external forces or vibrations in the closed state. This not only prevents the spillage of disposable items during transportation or storage, but also improves the safety of the product and avoids the pollution or loss of disposable items caused by accidental opening. At the same time, when designing, it is considered to be convenient for users to operate to ensure the convenience of locking and unlocking.

[0037] Working principle:

[0038] Initial state: The disposable item is placed on the pushing plate 4, the pushing plate 4 is at the bottom, and the elastic member 10 is pre-compressed;

[0039] Extraction process: After the user takes out the disposable item from the extraction port 2, the load on the pushing plate 4 is reduced, and the restoring force of the elastic member 10 drives the pushing plate 4 to rise;

[0040] Rising process: The pulley 5 rolls on the arc-shaped slide rail 7 to provide guidance. The angle change of the elastic member 10 and the arc-shaped slide rail 7 ensures the balance of the pushing force, and the pushing plate 4 rises smoothly;

[0041] Positioning: The pushing plate 4 rises to a position close to the opening of the box body 3, and the disposable item is in the best extraction position.

[0042] The above are only the preferred embodiments of the present utility model, and thus do not limit the implementation manners and protection scope of the present utility model. For those skilled in the art, it should be realized that all the equivalent replacements and obvious changes made by using the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
