Description

Technical Field

[0001] This utility model relates to the field of PP board technology, specifically to a PP board with an adjustable structure. Background Technology

[0002] PP sheet, also known as polypropylene (PP) sheet, is a semi-crystalline material. It is harder and has a higher melting point than PE. Because homopolymer PP becomes very brittle above 0°C, many commercial PP materials are random copolymers with 1% to 4% ethylene or block copolymers with higher ethylene content.

[0003] According to Chinese Patent Publication No. CN222141716U, a PP plate with an adjustable structure is disclosed. When the main PP plate is extended or retracted, a telescopic cylinder at the rear end slides out the adjustable PP plate and sliding rod inside the sliding groove, facilitating the extension of the adjustable PP plate's position and length. This increases the convenience of use and improves the flexibility of the device during extension. However, in this technical solution, after the adjustable PP plate extends from the main PP plate, a cavity is created inside the main PP plate. Since this cavity lacks a supporting structure, the strength of the main PP plate is reduced, making it prone to deformation and affecting the overall performance of the PP plate. Therefore, we propose a PP plate with an adjustable structure. Utility Model Content

[0004] The purpose of this invention is to provide a PP board with an adjustable structure, which solves the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a PP plate with an adjustable structure, comprising a main PP plate and a secondary PP plate. The main PP plate has shrinkage cavities extending through both sides. Two secondary PP plates are respectively inserted into the two ends of the shrinkage cavities. A second fixing plate is fixedly installed on the inner wall of the shrinkage cavities. A bidirectional screw is movably threaded through the second fixing plate, and the bidirectional screw is rotatably connected to the second fixing plate via bearings. The two secondary PP plates are respectively threaded onto the two ends of the bidirectional screw. A groove is formed on the front of the main PP plate, and a rotating shaft extends through the inner wall of the groove. The rotating shaft is rotatably connected to the main PP plate via bearings, and the rotating shaft is drively connected to the bidirectional screw.

[0006] A fixed support plate is fixedly installed on the inner wall of the shrinkage cavity. From right to left, movable support plate one, movable support plate two, and movable support plate three are slidably connected to the inner wall of the shrinkage cavity near the auxiliary PP plate. A magnetic assembly one is installed between the fixed support plate and movable support plate one. A magnetic assembly two is installed between movable support plate one and movable support plate two. A magnetic assembly three is installed between movable support plate two and movable support plate three. A magnetic assembly four is installed between movable support plate three and the auxiliary PP plate.

[0007] Preferably, each of the magnetic groups one, two, three, and four includes magnetic strip one and magnetic strip two. The magnetic surfaces of magnetic strip one and magnetic strip two have opposite magnetic properties, and the magnetic properties of magnetic groups one, two, three, and four increase sequentially. By setting magnetic groups one, two, three, and four, movable support plates one, two, and three can move with the auxiliary PP plate and can detach from each other sequentially.

[0008] Preferably, limiting magnetic blocks are fixedly installed at the top ends of the movable support plate 1, movable support plate 2, and movable support plate 3. Limiting groove 1, limiting groove 2, and limiting groove 3 are formed at the top and bottom ends of the inner wall of the contraction cavity. The limiting magnetic blocks at the top ends of the movable support plate 1, movable support plate 2, and movable support plate 3 are slidably connected to the limiting groove 1, limiting groove 2, and limiting groove 3, respectively. An adsorption magnetic block is fixedly installed at one end of the inner wall of the limiting groove 1, limiting groove 2, and limiting groove 3. The magnetic properties of the adsorption magnetic block and the limiting magnetic block are opposite. By setting the limiting groove 1, limiting groove 2, and limiting groove 3, the movable support plate 1, movable support plate 2, and movable support plate 3 can be limited. By setting the adsorption magnetic block and the limiting magnetic block, the movable support plate 1, movable support plate 2, and movable support plate 3 can be fixed when contracting the cavity, thereby improving the stability of the movable support plate 1, movable support plate 2, and movable support plate 3.

[0009] Preferably, a knob is fixedly installed at one end of the rotating shaft, a bevel gear one is fixedly installed at the other end of the rotating shaft, and a bevel gear two is fixedly sleeved on the outer wall of the bidirectional screw, with the bevel gear one meshing with the bevel gear two.

[0010] Preferably, a fixing plate is rotatably sleeved on the outer wall of the rotating shaft via a bearing. The fixing plate is fixedly installed on the inner wall of the shrinkage cavity. By setting the fixing plate, the rotating shaft can be supported, thereby improving the stability of the rotating shaft during rotation.

[0011] Preferably, a limiting slide plate is fixedly installed on the outer wall of both auxiliary PP plates, and a limiting groove is formed on the inner wall of the shrinkage cavity. The limiting slide plate and the limiting groove are slidably connected. By setting the limiting slide plate and the limiting groove, the auxiliary PP plate can be limited in the shrinkage cavity, preventing the auxiliary PP plate from detaching from the main PP plate and ensuring the stability of the main PP plate and auxiliary PP plate when used together.

[0012] This invention provides a PP sheet with an adjustable structure. The PP sheet with the adjustable structure has the following advantages:

[0013] (1) The PP plate with the adjustable structure can enable the movable support plate 1, movable support plate 2 and movable support plate 3 to support the shrinkage cavity after the auxiliary PP plate extends, thereby ensuring the strength of the main PP plate during use, reducing the limitations of use, and solving the problem in the prior art that after the adjustable PP plate extends the main PP plate, a cavity is generated inside the main PP plate, and the cavity does not have a support structure, which leads to a reduction in the strength of the main PP plate and easy deformation, thus affecting the overall use effect of the PP plate;

[0014] (2) The PP plate with the adjustable structure can limit the secondary PP plate in the shrinkage cavity by setting the limiting slide plate and the limiting slide groove, so as to prevent the secondary PP plate from detaching from the main PP plate and ensure the stability of the main PP plate and the secondary PP plate in combination. The structure is simple and the practicality is strong. Attached Figure Description

In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] like Figure 1-8As shown, this utility model provides a technical solution: a PP plate with an adjustable structure, including a main PP plate 1 and a secondary PP plate 2. The main PP plate 1 has a shrinkage cavity 3 through both sides. There are two secondary PP plates 2, which are respectively inserted into the two ends of the shrinkage cavity 3. A fixing plate 26 is fixedly installed on the inner wall of the shrinkage cavity 3. A bidirectional screw 4 is movably passed through the fixing plate 26 and is rotatably connected to the fixing plate 26 through a bearing. The two secondary PP plates 2 are respectively threaded onto the two ends of the bidirectional screw 4. The main PP plate 1 has a groove 25 on the front side. A rotating shaft 20 passes through the inner wall of the groove 25 and is rotatably connected to the main PP plate 1 through a bearing. The rotating shaft 20 is drively connected to the bidirectional screw 4.

[0028] A fixed support plate 5 is fixedly installed on the inner wall of the shrinkage cavity 3. From right to left, movable support plate 1 6, movable support plate 2 7 and movable support plate 3 8 are slidably connected on the inner wall of the shrinkage cavity 3 near the auxiliary PP plate 2. A magnetic group 12 is installed between the fixed support plate 5 and the movable support plate 1 6. A magnetic group 2 13 is installed between the movable support plate 1 6 and the movable support plate 2 7. A magnetic group 3 14 is installed between the movable support plate 2 7 and the movable support plate 3 8. A magnetic group 4 15 is installed between the movable support plate 3 8 and the auxiliary PP plate 2.

[0029] A knob 24 is fixedly installed at one end of the rotating shaft 20, and a bevel gear 21 is fixedly installed at the other end of the rotating shaft 20. A bevel gear 22 is fixedly sleeved on the outer wall of the bidirectional screw 4, and the bevel gear 21 meshes with the bevel gear 22.

[0030] Specifically, in the above technical solution, when the length of the PP plate with the adjustment structure needs to be adjusted, the knob 24 can be directly rotated. The knob 24 drives the rotating shaft 20 to rotate, the rotating shaft 20 drives the first bevel gear 21 to rotate, the first bevel gear 21 drives the second bevel gear 22 to rotate, the second bevel gear 22 drives the bidirectional screw 4 to rotate, and the bidirectional screw 4 drives the two auxiliary PP plates 2 to extend outward into the shrinkage cavity 3, thereby increasing the overall length of the main PP plate 1. During the outward extension process, the auxiliary PP plates 2 will drive the movable support plate 1 6, the movable support plate 2 7, and the movable support plate 3 8 to slide in the shrinkage cavity 3, so that the movable support plate 1 6, the movable support plate 2 7, and the movable support plate 3 8 slide in the shrinkage cavity 3. Under the action of the limiting magnetic block 9 and the limiting slide grooves 10, 2, and 3, the support plate 3 8 can automatically disengage sequentially according to the extension length of the auxiliary PP plate 2. This allows the movable support plate 1 6, movable support plate 2 7, and movable support plate 3 8 to support the shrinkage cavity 3 after the auxiliary PP plate 2 extends, thereby ensuring the strength of the main PP plate 1 during use, reducing usage limitations, and solving the problem in the existing technical solution where, after the adjustment PP plate extends from the main PP plate, a cavity is generated inside the main PP plate, and the cavity lacks a supporting structure, resulting in reduced strength of the main PP plate, easy deformation, and thus affecting the overall performance of the PP plate.

[0031] Furthermore, magnetic groups 12, 13, 14 and 15 each include magnetic strip 1 and magnetic strip 2. The magnetic properties of the opposite sides of magnetic strip 1 and magnetic strip 2 are opposite, and the magnetic properties of magnetic groups 12, 13, 14 and 15 increase sequentially.

[0032] By setting up magnetic group 12, magnetic group 23, magnetic group 34 and magnetic group 45, the movable support plate 16, movable support plate 27 and movable support plate 38 can move along with the auxiliary PP plate 2 and can detach from each other in sequence.

[0033] Furthermore, limit magnets 9 are fixedly installed at the top of movable support plate 1 6, movable support plate 2 7, and movable support plate 3 8. Limiting grooves 1 10, 2 16, and 3 17 are opened at the top and bottom of the inner wall of the contraction cavity 3. The limit magnets 9 at the top of movable support plate 1 6, movable support plate 2 7, and movable support plate 3 8 are slidably connected to the limiting grooves 1 10, 2 16, and 3 17 respectively. Adsorption magnets 27 are fixedly installed at one end of the inner wall of the limiting grooves 1 10, 2 16, and 3 17. The magnetic properties of the adsorption magnets 27 and the limiting magnets 9 are opposite. By setting the limiting grooves 1 10, 2 16, and 3 17, the movable support plate 1 6, movable support plate 2 7, and movable support plate 3 8 can be limited respectively.

[0034] By setting up the adsorption magnetic block 27 and the limiting magnetic block 9, the movable support plate 1 6, movable support plate 2 7 and movable support plate 3 8 can be fixed when the contraction cavity 3 is in place, thereby improving the stability of the movable support plate 1 6, movable support plate 2 7 and movable support plate 3 8.

[0035] Furthermore, a fixing plate 23 is rotatably sleeved on the outer wall of the rotating shaft 20 via a bearing, and the fixing plate 23 is fixedly installed on the inner wall of the shrinkage cavity 3.

[0036] The fixed plate 23 can support the rotating shaft 20 and improve its stability during rotation.

[0037] Furthermore, the outer walls of the two auxiliary PP plates 2 are fixedly installed with limiting slide plates 18, and the inner wall of the shrinkage cavity 3 is provided with limiting slide grooves 19, and the limiting slide plates 18 and limiting slide grooves 19 are slidably connected.

[0038] By setting the limiting slide plate 18 and the limiting slide groove 19, the auxiliary PP plate 2 can be limited in the shrinkage cavity 3, preventing the auxiliary PP plate 2 from detaching from the main PP plate 1 and ensuring the stability of the combination of the main PP plate 1 and the auxiliary PP plate 2.

[0039] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art.
