Description

Technical Field

[0001] This utility model relates to the field of rectangular tube technology, specifically to a rectangular tube that is easy to connect. Background Technology

[0002] Rectangular tubes are hollow, square-shaped steel pipes with lightweight, thin walls. They are also known as flat tubes, flat square tubes, or square-flat tubes, and are also called cold-formed steel profiles. They are made from Q235 hot-rolled or cold-rolled strip steel or coils, which are cold-bent and then high-frequency welded to form a square cross-section. Except for the increased wall thickness, the corner dimensions and edge straightness of hot-rolled extra-thick-walled square tubes reach or even exceed the level of resistance-welded cold-formed square tubes. While maintaining the same bending and torsional strength, they are lighter in weight. Therefore, they are widely used in building structures, machinery manufacturing, steel construction projects, shipbuilding, solar power generation supports, steel structure engineering, power engineering, power plants, agriculture and chemical machinery, and can also be used in glass curtain walls, automobile chassis and airports.

[0003] When using rectangular tubes, two rectangular tubes need to be joined and fixed together. However, the process of joining two rectangular tubes is cumbersome and requires staff to use external tools to complete the connection, which makes the connection of rectangular tubes inconvenient. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a rectangular tube that is easy to connect, which has the advantages of facilitating the connection of two rectangular tubes and solving the problem of inconvenience when connecting two rectangular tubes.

[0005] This utility model discloses a rectangular tube for easy docking, comprising a first tube body, a locking block on the left side of the first tube body, and a second tube body on the left side of the first tube body. A locking groove adapted to the locking block is formed on the right side of the inner cavity of the second tube body. Fixing components are provided on the front and back of both the first and second tube bodies. Each fixing component includes a connecting plate, the inner side of which is fixedly connected to the first tube body. A toothed plate is provided on the left side of the connecting plate, and limiting blocks are provided at the top and bottom of the toothed plate. A limiting plate is fitted onto the surface of the toothed plate, and the inner side of the limiting plate is fixedly connected to the second tube body. The top and bottom of the inner cavity of the limiting plate are provided with limiting grooves that match the limiting block. A frame is provided on the outer side of the limiting plate, and a pull rod is fitted inside the inner cavity of the frame. A pull ring is provided on the outer side of the pull rod, and a moving plate is provided on the inner side of the pull rod. A slider is provided on the top and bottom of the moving plate, and sliding grooves that match the sliders are provided on the top and bottom of the inner cavity of the frame. Springs are provided at the connection points between the top and bottom of the outer side of the moving plate and the frame. A slanted locking plate is provided on the inner side of the moving plate, and the inner side of the slanted locking plate engages with the toothed grooves on the toothed plate. This utility model is suitable for applications requiring adjustment of the first tube body. When the first tube body is docked and fixed, the first tube body first moves the connecting plate, which in turn moves the toothed plate. The toothed plate then inserts into the frame. The frame's limiting groove and limiting block cooperate with the toothed plate to move. During this movement, the teeth on the toothed plate push the inclined locking plate, which in turn moves the moving plate. The frame's sliding groove and slider cooperate with the moving plate to move it. The moving plate then compresses a spring, causing the locking block on the first tube body to engage with the locking groove on the second tube body. The spring's inertia then causes the moving plate to reset. The inclined plate is reset by moving the movable plate. When the inclined plate engages with the toothed groove on the toothed plate, it limits the movement of the toothed plate, thus enabling unidirectional movement. This makes fixing the first and second tubes more effective and convenient. When it is necessary to disassemble the first and second tubes, first pull the pull ring. The pull ring moves the pull rod outward, which in turn moves the movable plate and the inclined plate. When the inclined plate moves out of the toothed groove on the toothed plate, the first tube can be moved. When the toothed plate moves out of the limiting plate, the first and second tubes can be disassembled.

[0006] The present invention provides a rectangular tube that is easy to connect, wherein the left side of the first tube body is fixedly connected to the locking block by welding, and the surface of the locking block is in close contact with the locking groove.

[0007] The present invention provides a rectangular tube for easy connection, wherein the surface of the pull ring is covered with an anti-slip sleeve, and the inner cavity of the anti-slip sleeve is fixedly connected to the pull ring by an adhesive. The anti-slip sleeve can prevent the pull ring from slipping, thus preventing it from falling off when the user pulls it.

[0008] This utility model provides a rectangular tube for easy connection, wherein the inner side of the pull rod is fixedly connected to the movable plate by a connecting block, and the inner side of the pull rod is located at the center of the outer side of the movable plate. This utility model uses a connecting block to fix the connection between the pull rod and the movable plate, making the pull rod more stable when moving the movable plate, and avoiding the situation where the connection between the pull rod and the movable plate becomes loose, thus preventing the connection between the pull rod and the movable plate from breaking.

[0009] The present invention provides a rectangular tube that is easy to connect. The outer side of the limiting plate is fixedly connected to the frame by welding. The frame is located at the center of the outer side of the limiting plate. The connection between the frame and the limiting plate is fixed by welding. This makes the frame more stable when fixed on the limiting plate, avoiding the frame from shaking during use and thus preventing the unstable use of the components inside the frame.

[0010] The present invention provides a rectangular tube for easy docking, wherein the inclined surface of the inclined plate is not less than 45 degrees, and the inner side of the inclined plate is in close contact with the tooth groove on the toothed plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. When the first and second tubes need to be docked and fixed, the first tube first moves the connecting plate, which in turn moves the toothed plate. The toothed plate is then inserted into the frame. The frame's limiting groove and limiting block cooperate with the toothed plate to move. During this movement, the teeth on the toothed plate push the inclined locking plate, which in turn moves the moving plate. The frame's sliding groove and slider cooperate with the moving plate to move it. The moving plate then compresses a spring, causing the locking block on the first tube to engage with the locking groove on the second tube. The spring's inertia then... The movable plate is reset, which in turn drives the inclined plate to reset. When the inclined plate engages with the toothed groove on the toothed plate, it limits the movement of the toothed plate, thus enabling unidirectional movement. This method is more effective and convenient for fixing the first and second tubes. When it is necessary to disassemble the first and second tubes, first pull the pull ring. The pull ring drives the pull rod to move outward, which in turn moves the movable plate and the inclined plate. When the inclined plate moves out of the toothed groove on the toothed plate, the first tube can be moved. When the toothed plate moves out of the limiting plate, the first and second tubes can be disassembled.

[0013] 2. The present invention uses a connecting block to fix the connection between the pull rod and the moving plate, so that the pull rod is more stable when moving the moving plate, and avoids the connection between the pull rod and the moving plate from loosening, which could lead to the connection between the pull rod and the moving plate breaking.

[0014] The anti-slip sleeve prevents the pull ring from slipping, thus preventing it from falling off when the user pulls it.

[0015] The frame and the limiting plate are fixedly connected by welding, which makes the frame more stable on the limiting plate and avoids the frame shaking during use, thus preventing the unstable use of the components inside the frame. Attached Figure Description

Detailed Implementation

[0024] The following drawings will disclose several embodiments of this utility model. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these practical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0025] Please see Figures 1-6The present invention provides a rectangular tube for easy connection, comprising a first tube body 1, a locking block 5 on the left side of the first tube body 1, and a second tube body 2 on the left side of the first tube body 1. A locking groove 4, adapted to the locking block 5, is provided on the right side of the inner cavity of the second tube body 2. Fixing components 3 are provided on the front and back of both the first tube body 1 and the second tube body 2. Each fixing component 3 includes a connecting plate 301, the inner side of which is fixedly connected to the first tube body 1. A toothed plate 302 is provided on the left side of the connecting plate 301. Limiting blocks 303 are provided at the top and bottom of the toothed plate 302. A limiting plate 304 is fitted onto the surface of the toothed plate 302, the inner side of which is fixedly connected to the second tube body 2. Limiting grooves 3 adapted to the limiting blocks 303 are provided at the top and bottom of the inner cavity of the limiting plate 304. 06. A frame 305 is provided on the outer side of the limiting plate 304. A pull rod 307 is sleeved in the inner cavity of the frame 305. A pull ring 308 is provided on the outer side of the pull rod 307. A movable plate 3013 is provided on the inner side of the pull rod 307. A slider 3010 is provided at the top and bottom of the movable plate 3013. A groove 309 adapted to the slider 3010 is provided at the top and bottom of the inner cavity of the frame 305. A spring 3011 is provided at the connection between the top and bottom of the outer side of the movable plate 3013 and the frame 305. An inclined plate 3014 is provided on the inner side of the movable plate 3013, and the inner side of the inclined plate 3014 is engaged with the tooth groove on the toothed plate 302. When it is necessary to connect and fix the first tube 1 and the second tube 2, the first tube 1 first drives the connecting plate 301. The movement is achieved by connecting plate 301 driving toothed plate 302 to move. Toothed plate 302 is then inserted into frame 305. Limiting groove 306 and limiting block 303 within frame 305 cooperate with toothed plate 302 to move. During this movement, the teeth on toothed plate 302 push inclined plate 3014 to move, which in turn drives moving plate 3013. Sliding groove 309 and slider 3010 within frame 305 cooperate with moving plate 3013 to move. Moving plate 3013 drives spring 3011 to press, causing block 5 on first tube 1 to engage with slot 4 on second tube 2. The inertia of spring 3011 then causes moving plate 3013 to reset. The movable plate 3013 drives the inclined plate 3014 to reset. When the inclined plate 3014 is engaged in the toothed groove on the toothed plate 302, the toothed plate 302 can be limited, thus enabling the toothed plate 302 to move in one direction. This makes it more effective and convenient to fix the first tube 1 and the second tube 2. When it is necessary to disassemble the first tube 1 and the second tube 2, first pull the pull ring 308. The pull ring 308 drives the pull rod 307 to move outward. The pull rod 307 drives the movable plate 3013 and the inclined plate 3014 to move. When the inclined plate 3014 moves out of the toothed groove on the toothed plate 302, the first tube 1 can be moved. When the toothed plate 302 moves out of the limiting plate 304, the first tube 1 and the second tube 2 can be disassembled.

[0026] The left side of the first tube 1 is fixedly connected to the card block 5 by welding, and the surface of the card block 5 is in close contact with the card slot 4.

[0027] The surface of the pull ring 308 is covered with an anti-slip sleeve, and the inner cavity of the anti-slip sleeve is fixedly connected to the pull ring 308 by an adhesive. The anti-slip sleeve can prevent the pull ring 308 from slipping and prevent it from falling off when the user pulls the pull ring 308.

[0028] The inner side of the pull rod 307 is fixedly connected to the movable plate 3013 by a connecting block 3012, and the inner side of the pull rod 307 is located at the center of the outer side of the movable plate 3013. The connecting block 3012 can fix the connection between the pull rod 307 and the movable plate 3013, so that the pull rod 307 is more stable when moving the movable plate 3013, and avoids the connection between the pull rod 307 and the movable plate 3013 from becoming loose, which could lead to the connection between the pull rod 307 and the movable plate 3013 breaking.

[0029] The outer side of the limiting plate 304 is fixedly connected to the frame 305 by welding, and the frame 305 is located at the center of the outer side of the limiting plate 304. The connection between the frame 305 and the limiting plate 304 is fixedly connected by welding, so that the frame 305 is more stable on the limiting plate 304, avoiding the frame 305 from shaking during use, which would lead to the instability of the components inside the frame 305.

[0030] The inclined surface of the inclined plate 3014 is not less than 45 degrees, and the inner side of the inclined plate 3014 is in close contact with the tooth groove on the tooth plate 302.

[0031] When using this utility model: when it is necessary to connect and fix the first tube 1 and the second tube 2, the first tube 1 first moves the connecting plate 301, which in turn moves the toothed plate 302. At this time, the toothed plate 302 will be inserted into the frame 305. Then, the toothed plate 302 moves in conjunction with the limiting groove 306 and the limiting block 303 in the frame 305. During the movement of the toothed plate 302, the teeth on the toothed plate 302 will push the inclined locking plate 3014 to move. The inclined locking plate 3014 moves the moving plate 3013. The moving plate 3013 moves in conjunction with the sliding groove 309 and the slider 3010 in the frame 305. The moving plate 3013 drives the spring 3011 to press, and the locking block 5 on the first tube 1 engages with the locking groove 4 on the second tube 2. At this time, the spring... The inertia of 3011 drives the moving plate 3013 to reset, which in turn drives the inclined plate 3014 to reset. When the inclined plate 3014 is engaged in the toothed groove on the toothed plate 302, the toothed plate 302 can be limited, thus enabling the toothed plate 302 to move in one direction. This makes fixing the first tube 1 and the second tube 2 more effective and convenient. When it is necessary to disassemble the first tube 1 and the second tube 2, first pull the pull ring 308, which drives the pull rod 307 to move outward. The pull rod 307 drives the moving plate 3013 and the inclined plate 3014 to move. When the inclined plate 3014 moves out of the toothed groove on the toothed plate 302, the first tube 1 can be moved. When the toothed plate 302 moves out of the limiting plate 304, the first tube 1 and the second tube 2 can be disassembled.
