[0001] The invention relates to the technical field of storage devices, in particular to a transport mechanism for PLA straws. Background Art

[0002] PLA is the abbreviation of biodegradable plastic polylactic acid. Polylactic acid is a polymer obtained by polymerization of lactic acid as the main raw material. The raw material source is sufficient and renewable, mainly corn, cassava, etc. The production process of polylactic acid is pollution-free, and the product is biodegradable and can be recycled in nature, so it is an ideal green polymer material. Straws, or drinking straws, are cylindrical, hollow plastic products, and their main function is to drink beverages from cups. After production, PLA straws need to be packed and boxed for transportation.

[0003] Chinese patent CN214566804U, an environmentally friendly packaging carton, including a carton body with an opening upward, the carton body including an outer box body with an opening upward and an inner box body with an opening upward which is sleeved on the inner side of the carton body, a buffer partition is connected between the side surface of the outer box body and the side surface of the inner box body, and a collapse groove is formed between adjacent buffer partitions; a load-bearing grille is connected between the bottom surface of the outer box body and the bottom surface of the inner box body, and the collapse groove or the load-bearing grille is filled with degradable material particles.

[0004] However, this patent still has the following problems: the structure of the box lid is relatively weak, and because there is a gap between the box lids, its anti-extrusion performance is worse than that of the box body. As a result, during the transportation of PLA straws, the box lid is easily squeezed downward and contracted into the box body, which will then flatten the PLA straws, ultimately affecting the normal use of the PLA straws and causing resource waste. Summary of the invention

[0005] The purpose of the present application is to provide a transport mechanism for PLA straws. When the straws are transported, due to the close fit between the locking block and the locking port, and the tension of the spring, the cover is firmly fixed on the transport box, effectively preventing the cover from opening due to vibration or impact during transportation, and at the same time preventing the cover from being squeezed downward and contracted into the box to flatten the PLA straws, thereby effectively protecting the PLA straws during transportation.

[0006] To achieve the above-mentioned purpose, the present application provides a transportation mechanism for PLA straws, including a transportation box, a cover plate and a locking mechanism, wherein an installation slot is provided on the top of the transportation box, a hinge slot is provided on one side of the installation slot, and an insertion port is provided on the other side, a hinge shaft is provided in the hinge slot, a hinge block is provided on one side of the cover plate, and a mounting block is provided on the other side of the cover plate, the hinge block is hingedly arranged with the hinge shaft; the mounting block is adapted to the insertion port; the locking mechanism includes a locking block and a spring, telescopic slots are provided on both side walls of the mounting block, the locking block is arranged in the telescopic slot, and the side of the locking block located in the telescopic slot is connected to the inner wall of the telescopic slot by the spring; the side wall of the insertion port is provided with a locking port, and the locking block is adapted to the locking port; an unlocking mechanism is provided on the outer side wall of the transportation box, and the unlocking mechanism is used to compress the locking block into the telescopic slot to facilitate opening the cover plate.

[0007] As a further solution of the present invention: the unlocking mechanism includes an unlocking block and a pull plate, the unlocking block is arranged in the locking mouth and abuts against the side of the locking block inserted into the locking mouth; the side wall of the transport box is provided with an unlocking groove, the unlocking groove is provided with a sliding groove, the sliding groove is connected with the locking mouth, the pull plate is arranged in the unlocking groove, and one end of the pull plate passes through the sliding groove and is connected with the unlocking block, and the pull plate slides in cooperation with the sliding groove.

[0008] As a further solution of the present invention: a partition is arranged inside the transport box, and the partition divides the interior of the transport box into four areas. Guide grooves are provided on the inner wall of the transport box and the side wall of the partition. Limiting plates are arranged in the four areas, and guide blocks are arranged on both sides of the limiting plates. The guide blocks are slidably matched with the guide grooves, and the limiting plates limit the tops of the four areas.

[0009] As a further solution of the present invention: a grabbing groove is provided on the top of the limiting plate.

[0010] As a further solution of the present invention: the size of the limiting plate is adapted to the internal size of the four areas.

[0011] As a further solution of the present invention: a side of the locking block outside the telescopic slot is provided with a rounded corner, and the rounded corner faces the insertion port.

[0012] As a further solution of the present invention: a torsion spring is arranged between the hinge block and the hinge shaft.

[0013] As a further solution of the present invention: installation openings are provided on both sides of the transport box, and the installation openings are used to carry the transport box.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In the locked state, the cover is firmly fixed on the transport box due to the close fit between the locking block and the locking port and the tension of the spring, which effectively prevents the cover from opening due to vibration or impact during transportation. At the same time, it prevents the cover from being squeezed downward into the box to flatten the PLA straw, which can effectively protect the PLA straw during transportation.

[0016] 2. In the present invention, when it is necessary to open the cover plate, the operator first finds the unlocking slot on the side wall of the transport box and pulls the pull plate along the direction of the slide slot. Since the pull plate is connected to the unlocking block, this action will drive the unlocking block to move together. As the unlocking block moves, it gradually breaks away from the abutment relationship with the locking block. Under the elastic force of the spring, the locking block begins to retract inward and retreats into the telescopic slot. Once the locking block completely leaves the locking mouth, the cover plate is no longer restricted by the locking mechanism and can be easily opened. At the same time, since the pull plate is arranged in the unlocking slot, it is effectively prevented from being subjected to external pressure during transportation, thereby reducing damage.

[0017] 3. The present invention uses separation and limiting designs to keep the straws neatly arranged and firmly fixed during transportation, reducing the time for sorting and reloading caused by movement or scattering. At the same time, the limiting plate limits the top of the area, which can be used to stack straws of different quantities and specifications in the area, thereby improving the stability of the straws during transportation.

[0018] 4. The present invention can facilitate the movement or adjustment of the limit plate by setting the grabbing groove, thereby improving the overall work efficiency. By matching the size of the limit plate with the internal size of the four areas, it can ensure that the limit plate is firmly set at the designated position during transportation, preventing shaking or displacement caused by size mismatch, and improving the stability of straw transportation.

[0019] 5. The present invention provides rounded corners so that the locking block can slide into the locking opening more smoothly during the locking process, thereby reducing friction and resistance, thereby improving the locking efficiency and extending the service life of the equipment.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] like Figures 1 to 6 As shown, a transport mechanism for PLA straws includes a transport box 1, a cover plate 2 and a locking mechanism. A mounting groove 11 is provided on the top of the transport box 1, a hinge groove 12 is provided on one side of the mounting groove 11, and an insertion port 13 is provided on the other side. A hinge shaft 14 is provided in the hinge groove 12, a hinge block 21 is provided on one side of the cover plate 2, and a mounting block 22 is provided on the other side of the cover plate 2, the hinge block 21 is hingedly arranged with the hinge shaft 14; the mounting block 22 is adapted to the insertion port 13; when the PLA straws need to be placed in the transport box 1 for transportation, the cover plate 2 is rotated to open the top of the transport box 1 through the cooperation of the hinge block 21 and the hinge shaft 14, so as to facilitate the placement of the PLA straws.

[0030] The locking mechanism includes a locking block 23 and a spring 24. Telescopic grooves 221 are provided on the side walls of both sides of the mounting block 22. The locking block 23 is arranged in the telescopic groove 221, and the spring 24 is connected to the inner wall of the telescopic groove 221 on one side of the locking block 23 located in the telescopic groove 221; a locking opening 16 is provided on the side wall of the insertion port 13, and the locking block 23 is adapted to the locking opening 16; after the straw is placed, the side of the cover plate 2 with the mounting block 22 is placed into the insertion port 13. At this time, the locking blocks 23 on both sides of the mounting block 22 pop outward under the action of the spring 24 and match with the locking opening 16 on the side wall of the transport box 1 to complete the locking process.

[0031] In the locked state, due to the close fit between the locking block 23 and the locking opening 16, and the tension of the spring 24, the cover 2 is firmly fixed on the transport box 1, effectively preventing the cover 2 from opening due to vibration or impact during transportation, and at the same time preventing the cover 2 from being squeezed downward into the box body and flattening the PLA straws, thereby effectively protecting the PLA straws during transportation.

[0032] The outer side wall of the transport box 1 is provided with an unlocking mechanism, which is used to compress the locking block 23 into the telescopic slot 221 to facilitate opening the cover 2. The unlocking mechanism includes an unlocking block 3 and a pull plate 31, wherein the unlocking block 3 is arranged in the locking opening 16 and abuts against the side of the locking block 23 inserted into the locking opening 16; the side wall of the transport box 1 is provided with an unlocking slot 17, wherein a slide slot 18 is provided on the unlocking slot 17, wherein the slide slot 18 is communicated with the locking opening 16, wherein the pull plate 31 is arranged in the unlocking slot 17, and one end of the pull plate 31 passes through the slide slot 18 and is connected to the unlocking block 3, wherein the pull plate 31 and the slide slot 18 are slidably matched.

[0033] In the locked state, the locking block 23 is inserted into the locking opening 16 under the action of the spring 24, and abuts against the unlocking block 3 set in the locking opening 16. At this time, one end of the pull plate 31 passes through the slide groove 18 and is connected to the unlocking block 3, but the pull plate 31 itself does not hinder the closing or locking process of the cover plate 2. When the cover plate 2 needs to be opened, the operator first finds the unlocking groove 17 on the side wall of the transport box 1, and pulls the pull plate 31 along the direction of the slide groove 18. Since the pull plate 31 is connected to the unlocking block 3, this action will drive the unlocking block 3 to move together. As the unlocking block 3 moves, it gradually breaks away from the abutment relationship with the locking block 23. The locking block 23 begins to retract inward under the elastic force of the spring 24 and retreats into the telescopic groove 221. Once the locking block 23 completely leaves the locking opening 16, the cover plate 2 is no longer restricted by the locking mechanism and can be easily opened. At the same time, since the pull plate 31 is set in the unlocking groove 17, it is effectively avoided that the pull plate 31 is subjected to external pressure during transportation, reducing damage.

[0034] The transport box 1 is provided with a partition 4 inside, and the partition 4 divides the inside of the transport box 1 into four areas, which helps to store straws of different types, specifications or batches separately to avoid confusion and cross contamination.

[0035] The inner wall of the transport box 1 and the side wall of the partition 4 are provided with guide grooves 41, wherein limit plates 5 are arranged in four areas, guide blocks 51 are arranged on both sides of the limit plates 5, the guide blocks 51 are slidably matched with the guide grooves 41, and the limit plates 5 limit the tops of the four areas.

[0036] Through the separation and limiting design, the straws can be neatly arranged and firmly fixed during transportation, reducing the sorting and reloading time caused by movement or scattering. At the same time, the limiting plate 5 limits the top of the area, which can be used for the stacking height of straws of different quantities and specifications in the area, thereby improving the stability of the straws during transportation.

[0037] A grabbing groove 52 is formed on the top of the limiting plate 5 , and the size of the limiting plate 5 is adapted to the internal size of the four regions.

[0038] By providing the grabbing groove 52, the limiting plate 5 can be easily moved or adjusted, thereby improving the overall work efficiency. By matching the size of the limiting plate 5 with the internal size of the four regions, it can be ensured that the limiting plate 5 is firmly set at the designated position during transportation, preventing shaking or displacement caused by size mismatch, thereby improving the stability of straw transportation.

[0039] A rounded corner 231 is disposed on one side of the locking block 23 outside the telescopic slot 221 , and the rounded corner 231 faces the insertion opening 13 .

[0040] By providing the rounded corners 231 , the locking block 23 can slide more smoothly into the locking opening 16 during the locking process, thereby reducing friction and resistance, thereby improving the locking efficiency and extending the service life of the device.

[0041] A torsion spring 15 is provided between the hinge block 21 and the hinge shaft 14 .

[0042] By providing the torsion spring 15, after the cover plate 2 is unlocked, the cover plate 2 can be automatically opened, thereby improving the efficiency of installing and removing the straw.

[0043] Installation openings 19 are provided on both sides of the transport box 1 , and the installation openings 19 are used for carrying the transport box 1 .

[0044] The working principle of the present invention is as follows: when installing the straw, the cover plate 2 can be flexibly rotated to open the top of the transport box 1 through the cooperation of the hinge block 21 and the hinge shaft 14, so as to facilitate the insertion of the straw. After the straw is inserted, the locking block 23 in the locking mechanism automatically pops out and fits with the locking port 16 under the action of the spring 24, so as to achieve the firm locking of the cover plate 2 and protect the straw from vibration and extrusion. When necessary, the pull plate 31 is pulled by the unlocking mechanism, and the unlocking block 3 moves to retract the locking block 23, and the cover plate 2 can be easily opened after unlocking. The partition plate 4 in the transport box 1 separates four areas, and the limit plate 5 slides with the guide block 51 through the guide groove 41 to ensure that the straws are neatly arranged and firmly fixed. The torsion spring 15 is arranged between the hinge block 21 and the hinge shaft 14, so as to facilitate the automatic opening of the cover plate 2 after unlocking, thereby improving the operating efficiency. The mounting ports 19 on both sides facilitate the carrying of the transport box 1.
