Description

Technical Field

[0001] This invention belongs to the field of plastic products technology, specifically a plastic product recycling and transportation device. Background Technology

[0002] Plastic products are various items made primarily from plastics. They are characterized by their light weight, good chemical stability, excellent electrical and thermal insulation, wide distribution of mechanical strength, and high specific strength. According to the material, they can be divided into PET, HDPE, PVC, etc. According to the molding characteristics, they can be divided into thermosetting and thermoplastic. Production methods include compression molding, extrusion molding, etc. They are widely used in daily life and industrial fields, such as beverage bottles, plastic bags, and pipes. However, they also have environmental problems such as producing toxic gases when burned and being difficult to decompose naturally, causing pollution to the environment.

[0003] When recycling plastic products, transportation devices are required. Most current transportation devices consist of a container for storage and rollers for movement. However, there is no sealing mechanism between the container and the lid. If rain occurs during transportation, rainwater may seep into the container through the gaps and damage the plastic products. In addition, the internal space of the container is fixed, which is inconvenient when recycling different quantities of different plastic products. Finally, there is no fixing mechanism. The self-locking of the rollers alone cannot guarantee the stability of the device during loading and unloading, which affects the loading and unloading operation. Therefore, those skilled in the art have proposed a plastic product recycling and transportation device to solve the problems mentioned in the background art. Summary of the Invention

[0007] Preferably, the adjustment assembly includes an adjustment groove, an adjustment block, a fixing hole, a cavity, a top rod, and a fixing rod. The adjustment groove is formed on the inner walls of both sides of the housing. The adjustment block is fixedly connected to both sides of the partition and slidably connected to the adjustment groove. Several sets of fixing holes are provided and formed on the inner wall of the adjustment groove. The cavity is formed inside the partition and extends through the adjustment block. The inner ends of the top rod and the fixing rod are both hemispherical and movably connected to the cavity. The size of the fixing rod is adapted to the size of the fixing hole.

[0008] Preferably, the adjusting assembly further includes a second slide groove, a second slider, a second spring, a pull block, a third slide groove, a third slider, and a third spring. The second slide groove and the third slide groove are both formed on the inner wall of the cavity and are located on the outer periphery of the top rod and the fixed rod, respectively. The second slider is fixedly connected to the outer periphery of the top rod and slidably connected to the second slide groove. The second spring is sleeved on the outer periphery of the top rod and its two ends are fixedly connected to the top of the second slider and the inner wall of the top of the second slide groove, respectively. The third slider is fixedly connected to the outer periphery of the fixed rod and slidably connected to the third slide groove. The third spring is sleeved on the outer periphery of the fixed rod and its two ends are fixedly connected to the inner wall of the third slider away from the top rod and the inner wall of the third slide groove away from the top rod, respectively. The elastic force of the second spring is greater than the sum of the elastic forces of the two sets of third springs. The pull block is fixedly connected to the top of the top rod.

[0009] Preferably, a handle is fixedly connected to one side of the box, and mounting bases are fixedly connected to the bottom of each of the four corners of the box, with a movable component inside the mounting base.

[0010] Preferably, the movable component includes a slot, a support plate, a support, a rotating groove, and a rotating shaft. The slot is located at the bottom of the mounting base, the support plate is movably connected to the slot, the support is fixedly connected to the outer end of the support plate, the rotating groove is located on the inner walls of both sides of the slot, and the rotating shaft is fixedly connected to both sides of the inner end of the support plate and rotatably connected to the rotating groove.

[0011] Preferably, the movable component further includes a mounting block, rollers, insertion holes, and insertion rods. The mounting block is fixedly connected to one side of the support plate, the rollers are mounted on the mounting block, the insertion holes are provided in two horizontal sets and two vertical sets, the insertion holes penetrate the inner walls of both sides of the slot and the mounting block, and the insertion rods are provided in two sets and are adapted to the size of the insertion holes.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention features a sealing assembly. Before closing the lid, a first slider slides along a first groove to compress a first spring. During this process, a connecting rod drives a piston to slide synchronously along the air chamber with the first slider, drawing air from the sealing ring into the air chamber through a connecting hole. When the sealing ring deflates and is submerged in the mounting groove, the lid is closed. The first slider is then released, and the first spring rebounds, causing the piston to slide in the opposite direction along the air chamber via the first slider and connecting rod. Air from the air chamber is then sent to the sealing ring through the connecting hole. When the sealing ring expands to fit tightly against the sealing groove, it seals the connection between the lid and the body. This design effectively enhances the sealing performance at the lid-body connection, preventing rainwater from seeping into the box and damaging plastic products. 2. This invention features an adjustment component. Pulling the pull block upward causes it to move the second slider upward along the second groove via the top rod, compressing the second spring. When the top rod moves away from between the two sets of fixed rods, the third spring rebounds and moves the fixed rod towards the center of the cavity via the third slider. When the fixed rod moves out of the fixed hole and into the cavity, the position of the partition can be adjusted by sliding the adjustment block along the adjustment groove. After adjusting to the appropriate position, releasing the pull block causes the second spring to rebound and move the top rod downward via the second slider. When the top rod contacts the fixed rod, it pushes the fixed rod to both sides. When the fixed rod is inserted into the fixed hole at the current position, the partition is fixed in the current position. This design allows the device to adjust the internal space size, making it suitable for recycling different quantities of different plastic products. 3. This invention incorporates a movable component. The insertion rod is moved out of the insertion hole, and then the rotating shaft rotates along the slot, causing the support plate and support to rotate synchronously. When the mounting block and rollers rotate with the support plate to a position perpendicular to the ground, the insertion rod is inserted into the two sets of horizontal insertion holes and passes through the mounting block, thus fixing the rollers at the current angle. At this point, the device can be moved using the rollers. After moving to the designated position, the insertion rod is moved out of the insertion hole, and then the support plate is rotated in the opposite direction to a position perpendicular to the ground. The insertion rod is then inserted into the two sets of vertical insertion holes and passes through the mounting block, thus fixing the support plate at the current angle. The device can then be fixed in the current position using the support. This design allows the device to freely switch between moving and fixed postures, facilitating movement while maintaining stability during loading and unloading. Attached Figure Description

Detailed Implementation

[0015] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0016] As attached Figure 1 To be continued Figure 7 As shown: Example 1: The present invention provides a plastic product recycling and transportation device, including a box body 1, a box cover 2 rotatably installed on the top of one side of the box body 1, a sealing component 3 provided at the connection between the box cover 2 and the box body 1, the sealing component 3 including a sealing groove 31, a mounting groove 32, a sealing ring 33, an air chamber 34, a piston 35, a connecting hole 36, a first sliding groove 37, a first sliding block 38, a first spring 39 and a connecting rod 310, and a handle 6 fixedly connected to one side of the box body 1.

[0017] Furthermore, a sealing groove 31 is formed on the top surface of the housing 1, an installation groove 32 is formed on the bottom surface of the housing cover 2, a sealing ring 33 is made of rubber and is hollow inside, the sealing ring 33 is installed inside the installation groove 32 and, after expansion, matches the size of the sealing groove 31, an air chamber 34 is formed inside the housing cover 2, a piston 35 is slidably connected to the air chamber 34 and is sized to match, a connecting hole 36 is formed on one side of the inner wall of the air chamber 34 and communicates with the sealing ring 33, a first sliding groove 37 is formed on the top surface of the housing cover 2 and communicates with the end of the air chamber 34 away from the connecting hole 36, a first slider 38 is slidably connected to the first sliding groove 37, a first spring 39 is installed inside the first sliding groove 37 and its two ends are respectively fixedly connected to the side of the first slider 38 away from the air chamber 34 and the inner wall of the first sliding groove 37 away from the air chamber 34, and a connecting rod 310 is movably connected to the air chamber 34 and the first sliding groove 37 and its two ends are respectively fixedly connected to the first slider 38 and the piston 35.

[0018] As can be seen from the above, before closing the lid 2, the first slider 38 is slid along the first groove 37 to compress the first spring 39. During this process, the connecting rod 310 will drive the piston 35 to slide synchronously along the air chamber 34 with the first slider 38 and draw the air in the sealing ring 33 into the air chamber 34 through the connecting hole 36. When the sealing ring 33 deflates and is submerged in the mounting groove 32, the lid 2 is closed. Then the first slider 38 is released, and the first spring 39 rebounds, which can drive the piston 35 to slide in the opposite direction along the air chamber 34 through the first slider 38 and the connecting rod 310. At this time, the air in the air chamber 34 is sent to the sealing ring 33 through the connecting hole 36. When the sealing ring 33 expands to fit tightly with the sealing groove 31, the connection between the lid 2 and the body 1 can be sealed.

[0019] Example 2: This example is basically the same as the previous example, except that a partition 4 is provided inside the box 1, and an adjustment component 5 is provided at the connection between the partition 4 and the box 1. The adjustment component 5 includes an adjustment groove 51, an adjustment block 52, a fixing hole 53, a cavity 54, a top rod 55, a fixing rod 56, a second slide groove 57, a second slider 58, a second spring 59, a pull block 510, a third slide groove 511, a third slider 512, and a third spring 513.

[0020] Furthermore, the adjusting groove 51 is formed on the inner walls of both sides of the housing 1, the adjusting block 52 is fixedly connected to both sides of the partition 4 and slidably connected to the adjusting groove 51, several sets of fixing holes 53 are provided and formed on the inner wall of the adjusting groove 51, the cavity 54 is formed inside the partition 4 and passes through the adjusting block 52, the inner ends of the top rod 55 and the fixing rod 56 are both hemispherical and movably connected to the cavity 54, the size of the fixing rod 56 is adapted to the fixing hole 53, the second sliding groove 57 and the third sliding groove 511 are both formed on the inner wall of the cavity 54 and are respectively located on the outer periphery of the top rod 55 and the fixing rod 56, and the second slider 58 is fixedly connected to the outer periphery of the top rod 55. The second spring 59 is sleeved on the outer periphery of the top rod 55 and its two ends are respectively fixedly connected to the top of the second slider 58 and the inner wall of the top of the second slide groove 57. The third slider 512 is fixedly connected to the outer periphery of the fixed rod 56 and slidably connected to the third slide groove 511. The third spring 513 is sleeved on the outer periphery of the fixed rod 56 and its two ends are respectively fixedly connected to the inner wall of the third slider 512 away from the top rod 55 and the inner wall of the third slide groove 511 away from the top rod 55. The elastic force of the second spring 59 is greater than the sum of the elastic forces of the two sets of third springs 513. The pull block 510 is fixedly connected to the top of the top rod 55.

[0021] As can be seen from the above, when it is necessary to recycle two different quantities of two plastic products, pulling the pull block 510 upward causes it to drive the second slider 58 to slide upward along the second slide groove 57 via the top rod 55, thus squeezing the second spring 59. When the top rod 55 moves away from between the two sets of fixed rods 56, the third spring 513 rebounds and drives the fixed rod 56 to move towards the center of the cavity 54 via the third slider 512. When the fixed rod 56 moves out of the fixed hole 53 and into the cavity 54, the adjusting block 52 can be slid along the adjusting groove 51 to adjust the spacer. Adjust the position of plate 4 to a suitable position, then release the pull block 510. The second spring 59 will rebound and drive the push rod 55 downward through the second slider 58. When the push rod 55 contacts the fixed rod 56, since the elastic force of the second spring 59 is greater than the sum of the elastic forces of the two sets of third springs 513, the push rod 55 will push the fixed rod 56 to both sides and squeeze the third spring 513 through the third slider 512. When the fixed rod 56 is inserted into the fixed hole 53 at the current position, the partition plate 4 can be fixed in the current position.

[0022] Example 3: This example is basically the same as the previous example, except that the bottom of the four corners of the box 1 is fixedly connected to the mounting base 7. The mounting base 7 is provided with a moving component 8. The moving component 8 includes a slot 81, a support plate 82, a support 83, a rotating slot 84, a rotating shaft 85, a mounting block 86, a roller 87, a socket 88 and a plug rod 89.

[0023] Furthermore, a slot 81 is formed at the bottom of the mounting base 7, a support plate 82 is movably connected to the slot 81, a support 83 is fixedly connected to the outer end of the support plate 82, a rotating groove 84 is formed on both sides of the inner wall of the slot 81, a rotating shaft 85 is fixedly connected to both sides of the inner end of the support plate 82 and rotatably connected to the rotating groove 84, and the moving component 8 also includes a mounting block 86, a roller 87, a socket 88 and a rod 89. The mounting block 86 is fixedly connected to one side of the support plate 82, the roller 87 is mounted on the mounting block 86, the socket 88 is provided with two sets horizontally and two sets vertically, the socket 88 passes through the inner walls on both sides of the slot 81 and the mounting block 86, and the rod 89 is provided with two sets and is adapted to the size of the socket 88.

[0024] As can be seen from the above, the insertion rod 89 is removed from the insertion hole 88, and then the rotating shaft 85 is rotated along the rotating groove 84 to drive the support plate 82 and the support 83 to rotate synchronously. When the mounting block 86 and the roller 87 rotate with the support plate 82 to be perpendicular to the ground, the insertion rod 89 is inserted into the two sets of horizontal insertion holes 88 and passes through the mounting block 86, thereby fixing the roller 87 at the current angle. At this time, the device can be moved by the roller 87. After moving to the designated position, the insertion rod 89 is removed from the insertion hole 88, and then the support plate 82 is rotated in the opposite direction to be perpendicular to the ground. At this time, the insertion rod 89 is inserted into the two sets of vertical insertion holes 88 and passes through the mounting block 86, thereby fixing the support plate 82 at the current angle. At this time, the device can be fixed in the current position by the support 83.

[0025] Working principle: First, remove the insertion rod 89 from the insertion hole 88. Then, rotate the rotating shaft 85 along the rotating groove 84 to drive the support plate 82 and the support 83 to rotate synchronously. When the mounting block 86 and the roller 87 rotate with the support plate 82 to be perpendicular to the ground, insert the insertion rod 89 into the two sets of horizontal insertion holes 88 and pass through the mounting block 86, thereby fixing the roller 87 at the current angle. At this time, the device can be moved by the roller 87. After moving to the designated position, remove the insertion rod 89 from the insertion hole 88. Then, rotate the support plate 82 in the opposite direction to make it perpendicular to the ground. At this time, insert the insertion rod 89 into the two sets of vertical insertion holes 88 and pass through the mounting block 86, thereby fixing the support plate 82 at the current angle. At this time, the device can be moved by the roller 87. The device can be fixed in its current position by seat 83. Then, the plastic products to be recycled are placed in the box 1 for collection. After the box 1 is full, the first slider 38 slides along the first slide groove 37 to compress the first spring 39. During this process, the connecting rod 310 drives the piston 35 to slide synchronously along the air chamber 34 with the first slider 38 and draw the air in the sealing ring 33 into the air chamber 34 through the connecting hole 36. When the sealing ring 33 deflates and is submerged in the mounting groove 32, the box cover 2 is closed, and then the first slider 38 is released. The first spring 39 rebounds and drives the piston 35 to slide in the opposite direction along the air chamber 34 through the first slider 38 and the connecting rod 310. At this time, the air in the air chamber 34 is released. Air is sent to the sealing ring 33 through the connecting hole 36. When the sealing ring 33 expands to fit tightly with the sealing groove 31, the connection between the box cover 2 and the box body 1 is sealed. Then, the device is switched to the moving position to transport plastic products. When different quantities of two kinds of plastic products need to be recycled, the pull block 510 is pulled upward to make it drive the second slider 58 to slide upward along the second slide groove 57 through the top rod 55 and squeeze the second spring 59. When the top rod 55 moves away from the two sets of fixed rods 56, the third spring 513 rebounds and drives the fixed rod 56 to move towards the center of the cavity 54 through the third slider 512. When the fixed rod 56 moves out of the fixed hole 53 and into the cavity 54, the device can be used to transport plastic products. When the partition 4 is inside the cavity 54, the position of the partition 4 can be adjusted by sliding the adjusting block 52 along the adjusting groove 51. After adjusting it to match the number of plastic products, the pull block 510 is released, and the second spring 59 rebounds, which drives the top rod 55 to move downward through the second slider 58. When the top rod 55 contacts the fixing rod 56, since the elastic force of the second spring 59 is greater than the sum of the elastic forces of the two sets of third springs 513, the top rod 55 will push the fixing rod 56 to both sides and squeeze the third spring 513 through the third slider 512. When the fixing rod 56 is inserted into the fixing hole 53 at the current position, the partition 4 can be fixed in the current position, thereby completing the adjustment of the internal space size of the box 1.
