Description

Technical Field

[0001] This utility model relates to the field of plastic sealing technology, specifically to a plastic seal. Background Technology

[0002] Plastic seals are keyless locks designed to prevent tampering. They are typically used to seal and mark items, containers, and transport vehicles to ensure their security and integrity during transportation and storage. They prevent unauthorized opening, alteration, or theft of goods during transport and storage, guaranteeing the safety of sealed items and information. They also help clarify responsibility; any breach of the seal is easily detected, allowing for determination of unauthorized opening. Plastic seals can be categorized into embedded plastic seals, new reusable plastic seals, and compression-type plastic seals. Snap-on plastic seals consist of a snap-on body, a snap-on base, and a bottom cover. The snap-on body has a horizontal end cap at the top, a toothed divider at the center of the bottom, snap-on legs on both sides, and snap-on barbs at the bottom of the snap-on legs. The snap-on base has snap-on holes and divider holes that match the snap-on legs and divider. There are two locking grooves between the two holes at the top, and a snap-on barb cavity at the bottom of the snap-on hole. The bottom cover has a through hole in the center that matches the columnar protrusion at the bottom of the divider.

[0003] Chinese patent publication number "CN219642432U" discloses "An Embedded Plastic Seal, relating to the logistics and transportation field. To address the problem of deformation of the hook and barb when the buckle legs are pressed into the buckle hole, resulting in significant friction between the hook and barb and the inner wall of the buckle hole, making it difficult to install the upper buckle into the lower buckle, i.e., the difficulty in assembling the plastic seal," the patent includes an upper buckle and a lower buckle. The bottom wall of the upper buckle has two grooves and two buckle legs. The top wall of the lower buckle has a corresponding groove. The patent describes a plastic seal with two snap-fit ​​holes, a locking hole on the snap-fit ​​leg, a locking groove between the two snap-fit ​​holes, and a locking element between the locking groove. This patent improves the convenience of assembling plastic seals. However, when using the above patent, the locking element is moved by an internal spring, causing it to lock in the locking hole to achieve the purpose of locking. But this makes it impossible to remove the locking element from the locking hole when opening the plastic seal later, making the plastic seal difficult to open. Therefore, we propose a plastic seal. Utility Model Content

[0004] The purpose of this utility model is to provide a plastic seal to solve the problem mentioned in the background art. However, when the above-mentioned patent is used, the locking member is moved by the internal spring, so that the locking member will be stuck in the locking hole to achieve the purpose of locking. However, this will make it impossible to remove the locking member from the locking hole when opening the plastic seal later, thus making the plastic seal difficult to open.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a plastic seal, comprising a lower buckle, a fixing plate, and a mounting groove. The fixing plate is fixedly connected between the inner sidewalls of the lower buckle. The mounting groove is formed on the left and right sides of the front sidewall of the lower buckle. Buckle slots are formed on the top left and right sides of the lower buckle. Buckle legs are inserted into the inner cavity of the buckle slots. An upper buckle is integrally formed on the top of the buckle legs. An easy-break seam is formed on the upper side of the front sidewall of the buckle legs. Locking grooves are formed on the lower side of the left and right sidewalls of the buckle legs. A first guide slope is formed on the bottom of the buckle legs.

[0006] As a further description of the above technical solution: The upper left and right sides of the front sidewall of the lower buckle are provided with grooves, and the bottom of the inner cavity of the groove is inlaid with a first magnet.

[0007] As a further description of the above technical solution: The lower buckle has pins inserted into its top left front side and top right front side, and the ends of the pins are inlaid with second magnets. Protective covers are rotatably connected to both sides of the front sidewall of the lower buckle.

[0008] As a further description of the above technical solution: Large springs are fixedly connected to the left and right side walls of the fixed plate, and a connecting plate is fixedly connected to the end of the large springs.

[0009] As a further description of the above technical solution: The left and right side walls of the connecting plate are fixedly connected with locking components, and the left and right side walls of the locking components are provided with second guide slopes.

[0010] As a further description of the above technical solution: A small spring is fixedly connected to the front wall of the inner cavity of the mounting groove, a movable plate is fixedly connected to the end of the small spring, and a cutting plate is fixedly connected to the rear wall of the movable plate.

[0011] As a further description of the above technical solution: A pressing rod is fixedly connected to the middle of the front side wall of the movable plate, and the end of the pressing rod passes through the mounting groove and extends to the front side wall of the lower buckle.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This plastic seal is opened by manually pressing the pressing rod, which moves the movable plate, which in turn moves the cutting blade. The cutting blade then moves towards the easily broken seam, cutting it and causing the buckle leg to break. This allows the lower and upper buckles to separate quickly, making the plastic seal easier to open and improving its performance.

[0013] 2. This plastic seal, by flipping the protective cover, covers the pressing rod. At the same time, one side of the protective cover is inserted into the groove. Then, by inserting a pin, the pin locks the protective cover, thus protecting the pressing rod and preventing accidental activation. Finally, the first magnet attracts the second magnet, preventing the pin from falling off, thereby preventing accidental activation of the plastic seal during use. Attached Figure Description

[0019] This utility model provides a plastic seal that is easy to open, improves the effectiveness of the plastic seal, and prevents accidental activation during use. Please refer to [link / reference needed]. Figure 1-5 It includes a lower buckle 100, a fixing plate 200, and a mounting groove 300; Please see Figure 1-5The lower buckle 100 has buckle grooves 110 on the top left and right sides, and buckle legs 120 are inserted into the inner cavity of the buckle grooves 110. An upper buckle 130 is integrally formed at the top of the buckle legs 120. An easy-break seam 140 is formed on the upper side of the front side wall of the buckle legs 120. Locking grooves 150 are formed on the lower sides of the left and right side walls of the buckle legs 120. A first guide slope 160 is formed at the bottom of the buckle legs 120. Grooves 170 are formed on the upper sides of the left and right sides of the front side wall of the lower buckle 100. A first magnet 171 is embedded at the bottom of the inner cavity of the groove 170. A buckle 130 is inserted into the top left front side and top right front side of the lower buckle 100. The pin 180 has a second magnet 181 embedded at its end. The front side wall of the lower buckle 100 is rotatably connected to the protective cover 190. By flipping the protective cover 190, the protective cover 190 covers the pressing rod 340. At the same time, one side of the protective cover 190 is inserted into the groove 170. Then, by inserting the pin 180, the pin 180 locks the protective cover 190, thereby protecting the pressing rod 340 from accidental contact. Finally, the first magnet 171 attracts the second magnet 181, thus preventing the pin 180 from falling off. In summary, this avoids accidental activation of the plastic seal during use.

[0020] Please see Figure 1-3 A fixing plate 200 is fixedly connected between the inner walls of the lower buckle 100. An installation groove 300 is formed on the left and right sides of the front wall of the lower buckle 100. Large springs 210 are fixedly connected to the left and right side walls of the fixing plate 200. A connecting plate 220 is fixedly connected to the end of the large springs 210. Locking members 230 are fixedly connected to the left and right side walls of the connecting plate 220. Second guide slopes 240 are formed on the left and right side walls of the locking members 230. A small spring 310 is fixedly connected to the front wall of the inner cavity of the installation groove 300. A movable plate 320 is fixedly connected to the end of the small spring 310. The rear wall of the movable plate 320 is fixed... A cutting plate 330 is connected to the front side wall of the movable plate 320, and a pressing rod 340 is fixedly connected to the middle of the front side wall. The end of the pressing rod 340 passes through the mounting groove 300 and extends to the front side wall of the lower buckle 100. By manually pressing the pressing rod 340, the pressing rod 340 drives the movable plate 320 to move, which in turn drives the cutting plate 330 to move. The cutting plate 330 then moves towards the easy breakage seam 140, which cuts the easy breakage seam 140, thereby causing the buckle leg 120 to break. This allows the lower buckle 100 and the upper buckle 130 to be separated quickly.

[0021] In summary, this makes the plastic seal easier to open and improves its effectiveness.

[0022] In practical use, those skilled in the art first insert the latch leg 120 of the upper latch 130 into the latch groove 110 of the lower latch 100. At this time, the first guide slope 160 at the bottom of the latch leg 120 contacts the second guide slope 240 of the locking member 230, causing the locking member 230 to slide under the cooperation of the first guide slope 160 and the second guide slope 240, so that the locking member 230 does not obstruct the insertion of the latch leg 120. Then, when the latch leg 120 is fully inserted into the latch groove 110, the large spring 210 drives the connecting plate 220 to rebound, thereby causing the locking member 230 to be inserted into the locking groove 150, thus locking the latch leg 120. Then, by flipping the protective cover 190, the lock is secured. The cover 190 covers the pressing rod 340, and one side of the cover 190 is inserted into the groove 170. Then, by inserting the pin 180, the first magnet 171 attracts the second magnet 181, so that the pin 180 locks the cover 190. When removing the plastic seal, the cover 190 is unlocked by pulling out the pin 180. Then, the cover 190 is flipped over to expose the pressing rod 340. Finally, the pressing rod 340 is pressed manually, which moves the movable plate 320. The movable plate 320 then moves the cutting piece 330, which cuts the easy-break seam 140, causing the latch leg 120 to break. In this way, the plastic seal can be removed.
