Description

Technical Field

[0001] This application relates to the field of gypsum board transportation technology, and in particular to a corner protection device for transporting paper-faced gypsum board. Background Technology

[0002] Currently, paper-faced gypsum board is made by using building gypsum as the main raw material, adding appropriate additives and fibers as the core, and using specially made paper as the surface. It is a type of board that is lightweight, soundproof, heatproof, has strong processing performance, and is easy to construct. In order to reduce the deformation of paper-faced gypsum board during transportation, it is usually stacked directly in the carriage of the transport vehicle for transport in bulk.

[0003] The existing technical solutions mentioned above have the following drawbacks: during transportation, the edges and corners of the stacked gypsum boards may collide with the inner wall of the carriage or other goods, causing the protective paper to tear, the gypsum core to be exposed or even crack, resulting in missing corners and broken edges, which interferes with the subsequent use of paper-faced gypsum boards. Utility Model Content

[0004] This application provides a corner protection device for transporting paper-faced gypsum board in order to protect the corners of the board during transportation.

[0005] The above-mentioned technical objective of this application is achieved through the following technical solution: A corner protection device for transporting paper-faced gypsum board includes a three-sided corner bracket consisting of a horizontal plate and two vertical plates, and a connecting structure connecting the three-sided corner bracket. The two vertical plates are perpendicular to each other and fixed to adjacent edges of the horizontal plate. Connecting grooves are provided at positions on the outer surfaces of the two vertical plates that are far apart from each other. The connecting grooves communicate with the side walls of the vertical plates, making the connecting grooves T-shaped. The connecting structure includes a fixed column, a telescopic plate slidably disposed inside the fixed column, and connecting rods disposed at the ends of the fixed column and the telescopic plate. The connecting rods are adapted to the connecting grooves and can be disposed in the connecting grooves. The telescopic plate slides along the axis of the fixed column, and the connecting rods are disposed at the two ends opposite to the fixed column and the telescopic plate.

[0006] By adopting the above technical solution, and by setting up a three-sided corner bracket and a connecting structure, the connecting structure includes a fixed column, a telescopic plate slidably set inside the fixed column, and a connecting rod set at the two ends opposite to the fixed column and the telescopic plate and adapted to the connecting groove. The three-sided corner bracket consists of a horizontal plate and two vertical plates that are perpendicular to each other and fixed to the adjacent edges of the horizontal plate. This allows the inner surface of the horizontal plate of the three-sided corner bracket to fit with the upper or lower surface of the stacked gypsum board, and the inner surface of the vertical plate to fit with the side wall of the gypsum board to wrap the edges and corners of the gypsum board and protect the edges and corners of the gypsum board. The outer surfaces of the two vertical plates are provided with connecting grooves at positions far apart from each other. The connecting grooves are connected to the side wall of the vertical plates in a T-shape. The connecting rod can be put into the connecting groove to realize the detachable connection between the connecting structure and the three-sided corner bracket, which facilitates the reuse of the protective structure. The telescopic plate can slide along the axis of the fixed column to adjust the overall length of the connecting structure, thereby installing two adjacent three-sided corner brackets at the edges and corners of the stacked gypsum board, thus protecting the edges and corners of the gypsum board during transportation.

[0007] Optionally, the fixed column end face is provided with a strip-shaped notch, the telescopic plate is adapted to the notch and is slidably disposed in the notch, the outer peripheral wall of the fixed column is rotatably sleeved with a drive cylinder at the end away from the connecting rod, the inner peripheral wall of the drive cylinder is provided with a thread at the end away from the connecting rod, the side wall of the telescopic plate is provided with a thread protruding from the peripheral wall of the fixed column, and the thread of the inner wall of the drive cylinder is screwed into the thread of the side wall of the telescopic plate.

[0008] By adopting the above technical solution, by opening a notch and setting a drive cylinder, the drive cylinder is rotatably sleeved on the outer peripheral wall of the fixed column away from the connecting rod, and the inner peripheral wall of the drive cylinder is provided with a thread away from the connecting rod. The side wall of the telescopic plate is provided with a thread that protrudes from the peripheral wall of the fixed column and engages with the thread of the inner wall of the drive cylinder. This allows the telescopic plate to fit with the notch and slide in the notch. When the drive cylinder rotates, it drives the telescopic plate to slide along the axis of the fixed column through the thread engagement, thereby adjusting the overall length of the connection structure to adapt to different sizes of gypsum board. At the same time, the drive cylinder restricts the sliding trajectory of the telescopic plate.

[0009] Optionally, the inner peripheral wall of the drive cylinder is coaxially provided with an annular rotating groove at the end near the connecting rod, and the peripheral wall of the fixed column is coaxially sleeved with a ring fitting adapted to the rotating groove at the end away from the connecting rod, and the ring fitting is rotatably disposed in the rotating groove.

[0010] By adopting the above technical solution, and by setting a ring, the ring and the rotating groove can rotate the drive cylinder to the end of the peripheral wall of the fixed column.

[0011] Optionally, a strip-shaped fixing groove is provided on the side of the connecting groove on the outer surface of the vertical plate away from the side wall of the vertical plate. The fixing groove is connected to the connecting groove and is slidably disposed in the fixing plate. The surface of the fixing plate is flush with the surface of the outer plate of the vertical plate, and the fixing plate can close the connecting groove.

[0012] By adopting the above technical solution, by opening a fixing groove and sliding a fixing plate in the fixing groove, the fixing plate can slide along the fixing groove. When the connecting rod is put into the connecting groove, the fixing plate can slide to the position of closing the connecting groove, restricting the connecting rod in the connecting groove and reducing the possibility of the connecting rod coming out of the connecting groove during transportation bumps and during the rotation of the drive cylinder.

[0013] Optionally, a limiting groove is provided on the side wall of the fixing groove, and a limiting member adapted to the limiting groove is provided on the end face of the fixing plate, and the limiting member is slidably disposed in the limiting groove.

[0014] By adopting the above technical solution, and by setting a limiting component, the limiting component and the limiting groove can restrict the sliding trajectory of the fixed plate, while reducing the possibility of the fixed plate separating from the fixed groove.

[0015] Optionally, the outer corners of the three-sided corner bracket are processed into chamfers.

[0016] By adopting the above technical solution, the chamfering of the outer corners of the three-sided corner brackets can make the outer corner edges smoother, eliminating the sharp parts of the outer corners. This reduces the chance of sharp outer corners scratching the hands and arms of workers when handling protective devices or loading and unloading plasterboard.

[0017] Optionally, one end of the outer peripheral wall of the drive cylinder is coaxially machined into a hexagonal shape.

[0018] By adopting the above technical solution, and by coaxially processing one end of the outer peripheral wall of the drive cylinder into a hexagonal shape, the outer peripheral wall of the drive cylinder can be formed into a hexagonal shape that facilitates the application of force, making it easier for workers to rotate the drive cylinder and improving the operational convenience when adjusting the length of the telescopic plate.

[0019] Optionally, when the length of the fully extended and retracted telescopic plate and the fixed column is greater than the length of the gypsum board, and the telescopic plate is completely located in the notch, the overall length of the fixed column and the telescopic plate is less than the width of the gypsum board.

[0020] By adopting the above technical solution, and by making the length of the fully extended and retracted telescopic plate and the fixed column greater than the length of the gypsum board, and the overall length of the fixed column and the telescopic plate less than the width of the gypsum board when the telescopic plate is completely in the notch, the connection structure can be adapted to the length of the gypsum board in the length direction and the width of the gypsum board in the width direction, thus meeting the connection protection requirements of the protection device in both the length and width directions of the gypsum board.

[0021] In summary, this application has the following technical effects: 1. By setting up a three-sided corner bracket and a connecting structure, the connecting structure includes a fixed column, a telescopic plate slidably set inside the fixed column, and a connecting rod set at the two ends opposite to the fixed column and the telescopic plate and adapted to the connecting groove. The three-sided corner bracket consists of a horizontal plate and two vertical plates that are perpendicular to each other and fixed to the adjacent edges of the horizontal plate. It can make the inner surface of the horizontal plate of the three-sided corner bracket fit with the upper or lower surface of the slab of paper-faced gypsum board, and the inner surface of the vertical plate fit with the side wall of the gypsum board to wrap the corners of the gypsum board and protect the corners of the paper-faced gypsum board. The outer surfaces of the two vertical plates are opened at positions far apart from each other. The connecting groove is connected to the side wall of the vertical plate in a T shape. The connecting rod can be put into the connecting groove to realize the detachable connection between the connecting structure and the three-sided corner bracket, which is convenient for the repeated use of the protective structure. The telescopic plate can slide along the axis of the fixed column to adjust the overall length of the connecting structure, thereby installing two adjacent three-sided corner brackets at the corners of the slab of paper-faced gypsum board, thus protecting the corners of the paper-faced gypsum board during transportation. 2. By setting a drive cylinder, the drive cylinder is rotatably sleeved on the outer peripheral wall of the fixed column away from the connecting rod, and the inner peripheral wall of the drive cylinder away from the connecting rod is provided with a thread. The side wall of the telescopic plate is provided with a thread that protrudes from the peripheral wall of the fixed column and engages with the thread of the inner wall of the drive cylinder. This allows the telescopic plate to fit with the notch and slide in the notch. When the drive cylinder rotates, it drives the telescopic plate to slide along the axis of the fixed column through the thread engagement, thereby adjusting the overall length of the connection structure to adapt to different sizes of gypsum board. At the same time, the drive cylinder restricts the sliding trajectory of the telescopic plate. 3. By setting chamfers at the outer corners of the three-sided corner brackets, the outer corner edges of the three-sided corner brackets can be made smoother, eliminating the sharp parts of the outer corners. This reduces the chance of sharp outer corners scratching the hands and arms of workers when handling protective devices or loading and unloading plasterboard. Attached Figure Description

[0024] The present application will be further described in detail below with reference to the accompanying drawings.

[0025] This application discloses a corner protection device for transporting paper-faced gypsum board, referring to... Figure 1 The protective device includes protective structures 1 installed at each corner of the stacked gypsum board, and connecting structures 2 for connecting the protective structures 1 on the same horizontal plane. The protective structures 1 can protect the corners of the stacked gypsum board during transportation, reducing the possibility of damage to the corners of the gypsum board due to bumps and collisions. The connecting structures 2 can detachably install and fix the protective structures 1, making it convenient for the protective structures 1 to be reused.

[0026] Combination Figure 1 and Figure 2 The protective structure 1 includes a three-sided corner bracket 11 consisting of a horizontal plate 111 and two vertical plates 112, and a fixed plate 15 slidably disposed on the outer surface of the three-sided corner bracket 11. The horizontal plate 111 and the vertical plates 112 are both square plates of the same specifications. The two vertical plates 112 are fixedly connected to the adjacent two edges of the horizontal plate 111, respectively. The surfaces of the vertical plates 112 are perpendicular to the surfaces of the horizontal plate 111, and the surfaces of the two vertical plates 112 are perpendicular to each other. The adjacent side walls of the two vertical plates 112 are fixedly connected to each other. The inner corner of the three-sided corner bracket 11 is adapted to the stack of gypsum board. The inner surface of the horizontal plate 111 is attached to the upper or lower surface of the stack of gypsum board, and the inner surface of the vertical plate 112 is attached to the side wall of the stack of gypsum board, thereby protecting the edges and corners of the gypsum board. The outer corner of the three-sided corner bracket 11 is processed into a chamfer to reduce the possibility of scratching the handling workers.

[0027] Combination Figure 1 and Figure 2 Both vertical plates 112 have connecting grooves 12 on their outer surfaces. These grooves are strip-shaped and their length is perpendicular to the surface of the horizontal plate 111. The connecting grooves 12 on the two vertical plates 112 are spaced apart from each other and spaced from the sidewalls of the connecting plates. The connecting grooves 12 are connected to the sidewalls of the vertical plates 112, making them T-shaped. A strip-shaped fixing groove 13 is formed on the side of the connecting groove 12 away from the sidewall of the vertical plate 112. The length of the fixing groove 13 is perpendicular to the length of the connecting groove 12, and it is connected to the connecting groove 12. The sidewall of the fixing groove 13 is flush with the end wall of the connecting groove 12. A fixing plate 15, a strip-shaped plate, is slidably disposed within the fixing groove 13. The surface of the fixing plate 15 is flush with the outer surface of the vertical plate 112, and the fixing plate 15 can close the connecting groove 12.

[0028] Combination Figure 1 and Figure 2The side wall of the fixing groove 13 is provided with a strip-shaped limiting groove 14. The length direction of the limiting groove 14 is parallel to the length direction of the fixing groove 13. The two end walls of the limiting groove 14 are flush with the end walls of the fixing groove 13 and the side walls of the connecting groove 12, respectively. The end face of the fixing plate 15 is provided with a limiting member 151 that is adapted to the limiting groove 14. The limiting member 151 is slidably disposed in the limiting groove 14. The limiting member 151 and the limiting groove 14 can restrict the sliding trajectory of the fixing plate 15 and reduce the possibility of the fixing plate 15 separating from the fixing groove 13.

[0029] Combination Figure 2 and Figure 3 The connecting structure 2 includes a fixed column 22, a telescopic plate 222 that is retractable and extendable within the fixed column 22, a connecting rod 21 located at the ends of the fixed column 22 and the telescopic plate 222 that are far apart from each other, and a drive cylinder 23 that is rotatably sleeved on the end of the peripheral wall of the fixed column 22. The fixed column 22 is a cylinder, and one end of the fixed column 22 has an inwardly facing strip-shaped notch 221. The telescopic plate 222 is a strip-shaped plate that fits into the notch 221, and the telescopic plate 222 can extend and retract along the axis of the fixed column 22 within the notch 221. The sidewall of the telescopic plate 222 is machined into a protruding arc surface, and the telescopic plate 222 is located in the notch 221. The telescopic plate 222 and the fixed column 22 form a complete cylinder. The connecting rod 21 is a cylinder. The end face of the fixed column 22 and the end face of the telescopic plate 222 are both fixed to the periphery of the connecting rod 21. The two sides of the telescopic plate 222 connected to the periphery of the connecting rod 21 are provided with a reinforcing part integrally formed with the telescopic plate 222 to enhance the connection strength between the telescopic plate 222 and the connecting rod 21.

[0030] Combination Figure 2 and Figure 3 The connecting rod 21, the fixed column 22, and the telescopic plate 222 are all T-shaped, and the connecting rod 21 is adapted to the connecting groove 12. The ends of the connecting rod 21, the fixed column 22, and the telescopic plate 222 can all be completely located in the connecting groove 12. The driving cylinder 23 is a cylinder, and the inner wall of the driving cylinder 23 is adapted to the peripheral wall of the fixed column 22. The driving cylinder 23 is away from the connecting rod 21. The inner peripheral wall of the driving cylinder 23 near the end of the connecting rod 21 is coaxially provided with an annular rotating groove 231. The peripheral wall of the fixed column 22 away from the connecting rod 21 is coaxially provided with a ring 223 adapted to the rotating groove 231. The ring 223 is rotatably disposed in the rotating groove 231. The ring 223 and the rotating groove 231 can rotate the driving cylinder 23 to be rotatably disposed at the end of the peripheral wall of the fixed column 22.

[0031] Combination Figure 2 and Figure 3The inner circumferential wall of the drive cylinder 23 is provided with a thread at the end away from the rotating groove 231, and the side wall of the telescopic plate 222 is provided with a thread protruding from the circumferential wall of the fixed column 22. The drive cylinder 23 is threadedly connected to the side wall of the telescopic plate 222. The rotation of the drive cylinder 23 drives the telescopic plate 222 to extend and retract in the notch 221 through the interlocking threads. At the same time, the drive cylinder 23 restricts the extension and retraction trajectory of the telescopic plate 222.

[0032] Combination Figure 2 and Figure 3 The protective structure 1 is installed at the corners of the stacked gypsum board. Two adjacent protective structures 1 are set in the connecting groove 12 by connecting rods 21. The connecting groove 12 is closed by fixing plate 15 to reduce the possibility of the connecting rods 21 separating from the connecting groove 12 when the drive cylinder 23 is rotated. Rotating the drive cylinder 23 causes the telescopic plate 222 to move closer to the bottom of the notch 221, so that the vertical plates 112 of the two adjacent triangular corner brackets 11 clamp the gypsum board, thus setting the protective structure 1 at the corners of the stacked gypsum board. The fully extended length of the telescopic plate 222 and the fixing column 22 is greater than the length of the gypsum board, and when the telescopic plate 222 is completely located in the notch 221, the overall length of the fixing column 22 and the telescopic plate 222 is less than the width of the gypsum board. The outer peripheral wall end of the drive cylinder 23 is coaxially machined into a hexagonal shape to facilitate the rotation of the drive cylinder 23.
