Description

Technical Field

[0001] The invention belongs to the technical field of paper packaging, and particularly relates to a light paper basket. Background Art

[0002] With the diversification and e-sales of products, more and more packaging boxes are widely used, and according to the different functions, the structure and function of cartons are also different. Packaging cartons are made of paper products and are used to package various items. Cartons are low-cost, easy to package, suitable for adding fillers, clean, etc., suitable for product factory packaging, item transportation, material sorting, etc.

[0003] Problems with existing technologies:

[0004] In the existing work of using large paper baskets for packaging and transportation, after the large paper basket is used once, there will be a lot of debris and sundries at the bottom of the inner part. When the paper basket needs to be put into use again, the sundries in the paper basket need to be cleaned. The traditional cleaning work mostly involves inverting the paper basket and shaking it to clean out the sundries gathered at the bottom. This inverted and shaking paper basket cleaning method is not easy to hold the basket and the flipping operation is inconvenient. In addition, since most of the existing paper baskets do not have the function of adjustable volume, the space occupied by them cannot be flexibly adjusted, thereby failing to solve the problem that the larger the paper basket, the more complicated the cleaning work. Summary of the invention

[0010] A ring body is fixedly connected to the inner center of the bottom basket seat through a support rod, and inner convex bodies are fixedly arranged in a circular array on the inner wall of the ring body.

[0011] The center rod is movably inserted through the bottom paperboard and the ring body in sequence, and the inner convex body is movably inserted into the interior of the straight groove. A baffle for limiting the moving distance is fixedly arranged at the bottom end of the straight groove.

[0012] Extension plates are symmetrically fixed on the outer walls of both sides of the bottom basket seat, and plug plates are movably assembled on the upper surfaces of the extension plates. Baffle bars are fixed on the upper surfaces of the extension plates, and a sinking groove for the baffle bars to be embedded is provided on one end surface of the plug plates, and an end stopper is integrally fixedly provided on one end of the plug plates.

[0013] The sub-screening plate is placed inside the bottom basket seat and below the center rod, and plug-in openings are symmetrically fixedly provided on the outer walls on both sides of the sub-screening plate, and one end of the plug-in plate is movably inserted into the plug-in opening.

[0014] The outer wall of the round paper basket is integrally fixed with a spiral branch channel, and the spiral branch channel is provided with oblique grooves equidistantly and spirally formed obliquely above the spiral branch channel.

[0015] A bottom ring body integrated with the spiral branch channel is arranged at the bottom of the outer wall of the round paper basket, and a top ring body integrated with the spiral branch channel is arranged at the top of the outer wall of the round paper basket.

[0016] An inner sliding bevel is symmetrically fixed on the inner wall of the outer circular basket, and the inner sliding bevel fits with the spiral branch. An oblique groove tooth is integrally fixed at the lower middle part of the inner sliding bevel, and the oblique groove tooth is movably embedded in the inner part of the oblique groove.

[0017] An inner extension groove is formed on the top outer wall of the outer circular basket, and handle bodies are symmetrically fixedly arranged on the outer walls on both sides of the inner extension groove.

[0018] Alignment stops are symmetrically fixedly arranged on both sides of the bottom of the bottom basket seat, and limit stops are fixedly arranged on both sides of the upper surface of the alignment stops, and one end of the alignment stops is provided with an entry slot for the handle body to pass through.

[0019] The technical effects achieved by the present invention are:

[0020] (1) The present invention places the bottom basket seat on the ground, and then controls the outer circular basket to rotate together with the circular paper basket, so that the circular paper basket and the bottom basket seat will rotate relative to each other. While the circular paper basket is rotating, the inner flap inside it will move up and down, so that the inner flap has an effect of up and down vibration. At this time, part of the debris on the upper surface of the inner flap will pass through the second through hole and the first through hole to be discharged from the circular paper basket, and the remaining part will fall on the surface of the bottom paper board. Then, with the help of the force of the rotating circular paper basket, the debris will be discharged through the first through hole again, and finally the cleaning work of discharging the debris can be easily realized. This process is convenient for cleaning large-volume paper baskets, and the operation of turning over and shaking the paper basket is omitted, making the cleaning work simple and fast.

[0021] (2) In the present invention, the screening plate is installed into the interior of the bottom basket seat, and then the plug plate is pushed in and inserted into the interior of the plug plate opening, thereby completing the fixed installation of the screening plate. Finally, the circular paper basket is rotated. During the process, objects with smaller particles will pass through through hole 2 and through hole 1 and finally fall into the interior of the screening plate. In this process, the relatively rotatable structure of the circular paper basket and the bottom basket seat can be used to achieve simple screening work, and two particles with large differences in particle size can be screened in advance, thereby increasing the function of the paper basket and making it suitable for storing and transporting a variety of items.

[0022] (3) The present invention first pulls the outer circular basket upward so that the inclined groove teeth leave the corresponding inclined grooves first, and then rotates the outer circular basket to make it rotate relative to the circular paper basket. At this time, the outer circular basket will simultaneously telescope with the circular paper basket. The portion of the outer circular basket extending from the top of the circular paper basket will increase the storage space of the paper basket, and vice versa. By utilizing the telescopic structure of the circular paper basket and the outer circular basket, the storage space of the paper basket can be flexibly changed, so that the paper basket has the characteristics of flexible and adjustable storage space, and can change its own occupied space according to the transportation volume of the corresponding items, and can save a certain amount of transportation space in the transportation work.

[0023] (4) In the present invention, when stacking multiple paper baskets, the portion of the top of the outer circular basket containing the inner extension groove is inserted into the interior of the bottom basket seat of another paper basket, and the handle body is passed through the slot opening. The paper basket located on the upper side is then rotated to rotate the handle body into the interior of the stacking stop. At this time, the extension plates at the bottom of the two paper baskets are just in a unified straight line. In terms of appearance, the multiple paper baskets after stacking are all oriented in the same direction, and the overall structure is more beautiful. In addition, the setting of the slot opening facilitates the rapid alignment and stacking of the two paper baskets, and the stacking stop can be used to hook the handle body, which can prevent the upper paper basket from tipping over and separating, thereby improving the stability of the multiple paper baskets after stacking.

DETAILED DESCRIPTION

[0034] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

[0035] like Figure 1-2As shown, a light paper basket comprises a round paper basket 1, a bottom basket seat 2 is rotatably mounted on the bottom end of the round paper basket 1, an outer round basket 3 is movably mounted on the outer surface of the round paper basket 1, an inner movable plate 4 is movably mounted on the inner bottom end of the round paper basket 1, and a screening plate 5 is detachably mounted inside the bottom basket seat 2.

[0036] Embodiment 1

[0037] See attached Figure 6 A bottom paperboard 105 is integrally fixedly provided at the bottom of the round paper basket 1, a through hole 106 is opened in a ring array on the surface of the bottom paperboard 105, a side spherical protrusion 107 is fixedly provided in a ring array on the edge of the upper surface of the bottom paperboard 105, and a blocking block 108 is fixedly provided in a ring array on the upper surface of the bottom paperboard 105, and the through hole 106 and the blocking block 108 are alternately arranged.

[0038] See attached Figure 6 and Figure 7 The inner movable plate 4 is placed above the bottom paperboard 105, and the surface of the inner movable plate 4 is provided with through holes 401 in a circular array. The blocking block 108 corresponds to the position of the through hole 401. The lower surface edge of the through hole 401 is fixedly provided with side spherical protrusions 402 in a circular array, and the side spherical protrusions 402 are in contact with the side spherical protrusion 1 107. A center rod 403 is fixedly connected to the center of the lower surface of the through hole 401, and a straight groove 404 is fixedly provided on the outer wall of the center rod 403 in a circular array.

[0039] See attached Figure 6 and Figure 7 A ring body 207 is fixedly connected to the inner center of the bottom basket seat 2 through a support rod 206, and an inner protrusion 208 is fixedly arranged on the inner wall of the ring body 207 in a circular array.

[0040] See attached Figure 7 The center rod 403 movably penetrates the bottom paperboard 105 and the ring body 207 in sequence, and the inner protrusion 208 is movably inserted into the interior of the straight groove 404. A baffle for limiting the moving distance is fixedly provided at the bottom end of the straight groove 404.

[0041] According to the above structure, the bottom basket seat 2 is placed on the ground, and then the outer circular basket 3 is controlled to rotate together with the circular paper basket 1. The circular paper basket 1 and the bottom basket seat 2 will rotate relatively, and the circular paper basket 1 will drive the bottom paperboard 105 at the bottom to rotate together, but the inner flap 4 located at the bottom end of the circular paper basket 1 will not rotate, so the bottom paperboard 105 will rotate relatively with the inner flap 4, and then under the contact guidance of the side spherical protrusion 2 402 and the side spherical protrusion 1 107, the inner flap 4 inside the circular paper basket 1 will move up and down while the circular paper basket 1 rotates. The reciprocating movement makes the inner flap 4 vibrate up and down, and at this time, part of the debris on the upper surface of the inner flap 4 will pass through the second through hole 401 and the first through hole 106 and be discharged from the round paper basket 1, and the remaining part will fall on the surface of the bottom paper board 105, and then with the help of the force of the rotating round paper basket 1, the debris will be discharged through the first through hole 106, and finally the cleaning work of the debris can be easily realized. This process is convenient for the cleaning work of large-volume paper baskets, eliminating the operation of turning over the paper basket and shaking it, making the cleaning work simple and fast.

[0042] The working principle of the present invention is as follows: after the round paper basket 1 is used for a period of time, a large amount of debris and sundries will usually gather at the bottom end thereof. At this time, the bottom basket seat 2 can be placed on the ground first, and then the outer round basket 3 can be controlled to rotate together with the round paper basket 1. At this time, the round paper basket 1 and the bottom basket seat 2 will rotate relative to each other, and the round paper basket 1 will drive the bottom paperboard 105 at the bottom thereof to rotate together. Since the center rod 403 penetrates the ring body 207 and the inner convex body 208 is inserted into the straight groove 404, the inner flap 4 at the bottom end of the round paper basket 1 will not rotate, and the bottom paperboard 105 will rotate relative to the inner flap 4. In addition, since the side spherical protrusion 202 and the side spherical protrusion 208 are inserted into the straight groove 404, the inner flap 4 at the bottom end of the round paper basket 1 will not rotate. The two protruding lateral arc surfaces 107 are arranged alternately and contact each other. Under the guidance of the two types of raised side arc surfaces, when the round paper basket 1 rotates, the inner flap 4 will reciprocate up and down inside the round paper basket 1, and the inner convex body 208 will reciprocate inside the straight groove 404 accordingly, and finally the inner flap 4 has an up and down vibration effect. At this time, part of the debris on the upper surface of the inner flap 4 will pass through the second through hole 401 and the first through hole 106 to be discharged from the round paper basket 1, and the remaining part will fall on the surface of the bottom paperboard 105, and then the force of the rotating round paper basket 1 will make this part of the debris be discharged through the first through hole 106 again, and finally the cleaning work of discharging the debris can be easily realized.

[0043] Embodiment 2

[0044] See attached Figure 4 and Figure 5The outer walls of both sides of the bottom basket seat 2 are symmetrically fixed with extension plates 201, and the upper surfaces of the extension plates 201 are movably assembled with plug plates 203. The upper surfaces of the extension plates 201 are fixed with stop bars 202, and one end surface of the plug plates 203 is provided with a sinking groove 204 for the stop bars 202 to be embedded, and one end of the plug plates 203 is integrally fixed with an end stop body 205.

[0045] See attached Figure 4 The sub-screening plate 5 is placed inside the bottom basket seat 2 and below the center rod 403 , and the outer walls on both sides of the sub-screening plate 5 are symmetrically fixed with plug-in openings 501 , and one end of the plug-in plate 203 is movably inserted into the plug-in opening 501 .

[0046] According to the above structure, firstly pull out the plug plate 203, then install the sieve plate 5 into the interior of the bottom basket seat 2, then push the plug plate 203 back in and insert it into the interior of the plug plate opening 501, and finally complete the fixed installation of the sieve plate 5, and finally rotate the circular paper basket 1 in the manner of the first embodiment, wherein objects with smaller particles will eventually fall into the interior of the sieve plate 5 through the second through hole 401 and the first through hole 106. In this process, the relatively rotatable structure of the circular paper basket 1 and the bottom basket seat 2 can be used to realize simple sieving work, and two kinds of particles with a large difference in particle size can be sieved in advance, thereby increasing the function of the paper basket and making it suitable for storing and transporting a variety of items.

[0047] The working principle of the present invention is: when it is necessary to use the round paper basket 1 to complete simple screening work, you only need to pull out the plug plate 203 first, and the stopper 202 will move inside the sinking groove 204 to limit the moving distance of the plug plate 203, then install the screening plate 5 into the bottom basket seat 2, and then push the plug plate 203 back in and insert it into the plug plate opening 501, finally completing the fixed installation of the screening plate 5, and then rotate the round paper basket 1 in the manner of Example 1, wherein objects with smaller particles will finally fall into the inside of the screening plate 5 through the second through hole 401 and the first through hole 106.

[0048] Embodiment 3

[0049] See attached Figure 3 A spiral branch channel 101 is fixedly arranged on the outer wall of the round paper basket 1, and oblique grooves 102 are spirally and equidistantly arranged obliquely above the spiral branch channel 101. A bottom ring body 103 integrated with the spiral branch channel 101 is arranged at the bottom of the outer wall of the round paper basket 1, and a top ring body 104 integrated with the spiral branch channel 101 is arranged at the top of the outer wall of the round paper basket 1.

[0050] See attached Figure 3The inner wall of the outer circular basket 3 is symmetrically fixed with an inner sliding bevel 303, and the inner sliding bevel 303 is in contact with the spiral branch 101. An oblique groove tooth 304 is integrally fixed at the lower middle part of the inner sliding bevel 303, and the oblique groove tooth 304 is movably embedded in the inside of the oblique groove 102.

[0051] According to the above structure, the outer circular basket 3 is first pulled upward to make the inclined groove teeth 304 leave the corresponding inclined grooves 102 first, and then the outer circular basket 3 is rotated to make it rotate relative to the circular paper basket 1, and the inner sliding inclined body 303 will move in contact with the spiral branch 101. At this time, the outer circular basket 3 will simultaneously move telescopically with the circular paper basket 1. The part of the outer circular basket 3 extending from the top of the circular paper basket 1 will increase the storage space of the paper basket, and vice versa. By utilizing the telescopic structure of the circular paper basket 1 and the outer circular basket 3, the storage space of the paper basket can be flexibly changed, so that the paper basket has the characteristics of flexible and adjustable storage space, and then the space occupied by itself can be changed according to the transportation volume of the corresponding items, and a certain amount of transportation space can be saved in the transportation work at the same time.

[0052] The working principle of the present invention is as follows: when the storage capacity of the paper basket needs to be changed, the outer circular basket 3 can be first pulled upwards to make the inclined groove teeth 304 leave the corresponding inclined grooves 102 first, and then the outer circular basket 3 is rotated to make it rotate relative to the circular paper basket 1, and the inner sliding inclined body 303 will move in contact with the spiral branch 101. At this time, the outer circular basket 3 will simultaneously telescope with the circular paper basket 1, and the portion of the outer circular basket 3 extending from the top of the circular paper basket 1 will increase the storage space of the paper basket, and vice versa.

[0053] Embodiment 4

[0054] See attached Figure 3 An inner extension groove 301 is formed on the top outer wall of the outer circular basket 3 , and handle bodies 302 are symmetrically fixedly provided on the outer walls on both sides of the inner extension groove 301 .

[0055] See attached Figure 8 The bottom sides of the bottom basket seat 2 are symmetrically fixed with alignment stops 209, and both sides of the upper surface of the alignment stops 209 are fixed with limit stops 211, and one end of the alignment stops 209 is provided with an entry slot 210 for the handle body 302 to pass through.

[0056] According to the above structure, when stacking multiple paper baskets, the portion of the top of the outer circular basket 3 containing the inner extension groove 301 is inserted into the interior of the bottom basket seat 2 of another paper basket, and the handle body 302 is passed through the slot entrance 210, and then the paper basket located on the top is rotated to rotate the handle body 302 into the interior of the stacking stop 209. At this time, the extension plates 201 at the bottom of the two paper baskets are just in a unified straight line. In terms of appearance, the orientations and positions of the multiple paper baskets after cumulative stacking are the same, and the overall structure is more beautiful. In addition, the setting of the slot entrance 210 facilitates the rapid alignment and stacking of the two paper baskets, and the stacking stop 209 can be used to hook the handle body 302, which can prevent the upper paper basket from tipping over and separating, thereby improving the stability of the multiple paper baskets after stacking.

[0057] The working principle of the present invention is as follows: when multiple paper baskets need to be stacked, the portion of the top of the outer circular basket 3 containing the inner extension groove 301 is inserted into the interior of the bottom basket seat 2 of another paper basket. During the process, the handle body 302 is passed through the slot opening 210, and then the paper basket located above is rotated to rotate the handle body 302 into the interior of the stacking stop 209. The limit stop 211 is used to limit the moving space of the handle body 302. At this time, the extension plates 201 at the bottom of the two paper baskets are just in the same straight line, and the stacking stop 209 can be used to hook the handle body 302 to prevent the upper paper basket from tipping over and separating.

[0058] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention.
