Description

Technical Field

[0001] This invention relates to the field of privacy protection and isolation for student beds, specifically to a student bed isolation device with privacy protection functions. Background Technology

[0002] A student bed isolation device with privacy protection is a device that provides students with private space and protects their personal privacy. Its main function is to ensure that students have adequate privacy in shared dormitories or collective living environments.

[0003] Existing devices typically use bed canopy frames to more effectively divide the space of student beds. By hanging curtains or drapes on the bed canopy frames, personal space is isolated. By wrapping curtains or drapes around the outside of the bed canopy frames, students' privacy is effectively protected, making it impossible for outsiders to see into the area inside the curtains or drapes.

[0004] However, due to prolonged use, the support rods on student beds wear out, age, or are used for other purposes, resulting in some support rods being missing around the perimeter of the beds. This makes it impossible to fully install the existing bed canopy frame used in privacy-protecting student bed isolation devices. Furthermore, the installation process for the existing bed canopy frame requires splicing the support rods together and inserting them one by one around the perimeter of the student bed, making the installation process complicated.

[0005] Furthermore, the widths of student beds in dormitories vary across different schools. Existing privacy-protecting bed partitions only accommodate beds of the same width, preventing beds of different widths from using the existing bed canopy frames and reducing their versatility.

[0006] To address this, a student bed isolation device with privacy protection features is proposed. Summary of the Invention

[0007] The purpose of this invention is to provide a student bed isolation device with privacy protection function to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a student bed isolation device with privacy protection function, comprising a crossbar and connecting columns, wherein the connecting columns are symmetrically fixedly connected to both sides of the crossbar, and the crossbar is provided with an extension adsorption component for adsorption to the wall and for telescopic movement, wherein:

[0009] The extended adsorption assembly includes a fixator, which is uniformly fixedly connected to the surface of the crossbar. Each of the connecting columns is fixedly connected to a columnar rod, and the columnar rod has a groove inside, with a telescopic rod slidably connected inside the groove.

[0010] The crossbar is equipped with a telescopic component for controlling its extension and retraction, wherein:

[0011] The telescopic assembly includes a connecting sleeve fitted onto the middle of the crossbar. A guide rod is fixedly connected to the outer wall of the connecting sleeve. A guide groove is formed inside the guide rod. A bevel gear rod is rotatably connected to one end of the guide groove near the connecting sleeve. A turntable is fixedly connected to one end of the bevel gear rod near the fixing device. A rotating rod is rotatably connected to one end of the guide groove near the turntable. A belt is driven to the surface of the rotating rod. Rotating rods are symmetrically rotatably connected to the inner wall of the guide rod. The belt is driven to the rotating rod near the turntable. A collar is fixedly connected to the surface of each rotating rod. A guide belt is driven to the collars. A fixing block is fixedly connected to the surface of the guide belt. A moving rod is slidably connected inside the guide groove. A moving groove is formed inside the moving rod. The end of the fixing block away from the belt is fixedly connected to the inner wall of the moving rod. A blocking block is fixedly connected inside the guide rod. Locking holes are evenly formed on the outer wall of the moving rod. A concave block is fixedly connected to the end of the guide rod away from the turntable. A cylinder is fixedly connected inside the concave block. A locking rod is rotatably connected to the surface of the cylinder.

[0012] As a further aspect of the present invention, the shape and dimensions of the end of the locking rod away from the cylinder match the shape and dimensions of the lock hole.

[0013] As a further embodiment of the present invention, the connecting sleeve located on the side away from the turntable is fixedly connected to the end of the moving rod away from the guide rod.

[0014] As a further embodiment of the present invention, the surface of the connecting column located on the side away from the fixing device is fixedly connected to the end of the telescopic rod away from the slide groove.

[0015] As a further embodiment of the present invention, a bevel gear is fixedly connected to the end of the bevel gear rod away from the turntable.

[0016] As a further embodiment of the present invention, a bevel gear is fixedly connected to the surface of the rotating rod.

[0017] As a further embodiment of the present invention, the bevel gear on the bevel gear rod meshes with the bevel gear on the rotating rod.

[0018] As a further embodiment of the present invention, the blocking block is positioned on the movement trajectory of the fixed block.

[0019] As a further embodiment of the present invention, the blocking block and the rotating rod below it slide within the motion groove.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. By evenly fixing the device to the horizontal bar and adhering it to the wall, the privacy-protecting student bed isolation device can be installed without the need for a support frame around the student bed. This avoids the problem of having to splice the support rods and insert them one by one around the student bed during the installation of existing privacy-protecting student bed isolation devices with bed canopies. This ensures that the installation process of the privacy-protecting student bed isolation device is simple for the operator.

[0022] 2. By sliding the telescopic rod inside the slide groove along with the moving rod, the operator can adjust the width of the privacy-protecting student bed isolation device according to the required width of the student bed. This avoids the problem that the bed canopy frame in the existing privacy-protecting student bed isolation device can only be adapted to student beds of the same width, making it impossible for student beds of different widths to use the bed canopy frame in the existing privacy-protecting student bed isolation device. This ensures the versatility of the privacy-protecting student bed isolation device.

Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0038] Please see Figures 1 to 10 As shown, this is an embodiment of the present invention: a student bed isolation device with privacy protection function, including a crossbar 1 and connecting columns 11, the connecting columns 11 being symmetrically fixedly connected to both sides of the crossbar 1, and the crossbar 1 being provided with an extension adsorption assembly for adsorption to the wall and for telescopic movement, wherein:

[0039] The extended adsorption assembly includes a fixture 21, which is uniformly fixedly connected to the surface of the crossbar 1. A columnar rod 22 is fixedly connected to the surface of the connecting column 11. A groove 23 is provided inside the columnar rod 22. A telescopic rod 24 is slidably connected inside the groove 23. The surface of the connecting column 11 located away from the fixture 21 is fixedly connected to the end of the telescopic rod 24 away from the groove 23.

[0040] Wherein: the fixing device 21 is evenly fixed on the horizontal bar 1 near the turntable 35. The end of the fixing device 21 away from the horizontal bar 1 is provided with a suction cup. The fixing device 21 is evenly fixedly connected to the surface of the horizontal bar 1 and the end of the fixing device 21 away from the horizontal bar 1 is adsorbed to the wall, which plays the role of fixing the horizontal bar 1. The suction cup on the fixing device 21 is made of rubber, which plays the role of enhancing the seal between the suction cup and the wall and the friction generated when the suction cup contacts the wall.

[0041] Even better: When the operator presses the suction cup on the end of the fixture 21 away from the crossbar 1 against the wall, the air inside the suction cup is squeezed out, thus creating a low-pressure area. The atmospheric pressure inside the suction cup adhering to the wall is lower than the outside atmospheric pressure. Because the high atmospheric pressure will move to the low atmospheric pressure area to balance the pressure difference, and the suction cup is a barrier between the outside atmosphere and the low-pressure area of ​​the suction cup, the pressure of the surrounding atmosphere firmly presses the suction cup against the wall. Through the suction cups on the fixtures 21 in the same horizontal straight line in the same vertical plane adhering to the wall, when the crossbar 1 is fixedly connected to the end of the fixtures 21 away from the suction cups on the fixtures 21, it is firmly fixed by the fixtures 21, so that the fixtures 21 are not pressed down by the weight of the crossbar 1 and the suction cups on the fixtures 21 fall off the wall.

[0042] Because the suction cup on the fixture 21 is made of rubber, when the operator presses the suction cup on the end of the fixture 21 away from the crossbar 1 against the wall, the rubber surface has a high coefficient of friction, which allows the rubber to provide greater friction when the suction cup contacts the wall. Under atmospheric pressure, this makes the suction cup adhere more firmly to the wall, reducing the occurrence of accidental slippage of the suction cup on the wall. At the same time, rubber is an elastic material that can better adapt to irregular surfaces, allowing the surface of the suction cup in contact with the wall to better contact the uneven wall surface. By using a rubber suction cup, the seal between the suction cup and the wall is enhanced, thereby improving the stability of the suction cup's adsorption. In addition, rubber has good durability and elasticity, which makes the suction cup more resistant to long-term use and deformation.

[0043] The crossbar 1 is equipped with a telescopic component for controlling its extension and retraction, wherein:

[0044] The telescopic assembly includes a connecting sleeve 31, which is fitted onto the middle of the crossbar 1. A guide rod 32 is fixedly connected to the outer wall of the connecting sleeve 31. A guide groove 33 is provided inside the guide rod 32. A bevel gear rod 34 is rotatably connected to the end of the guide groove 33 near the connecting sleeve 31. A turntable 35 is fixedly connected to the end of the bevel gear rod 34 near the fixing device 21. A bevel gear is fixedly connected to the end of the bevel gear rod 34 away from the turntable 35. A rotating rod 36 is rotatably connected to the end of the guide groove 33 near the turntable 35. A bevel gear is fixedly connected to the surface of the rotating rod 36. The bevel gear on the bevel gear rod 34 meshes with the bevel gear on the rotating rod 36. A belt 37 is driven to the surface of the rotating rod 36. A rotating rod 38 is symmetrically rotatably connected to the inner wall of the guide rod 32. The belt 37 is driven to the rotating rod 38 on the side near the turntable 35. A collar 39 is fixedly connected to the surface of each rotating rod 38. A guide belt 312 is driven to the collar 39. A fixing block 318 is fixedly connected to the surface of 312. A moving rod 310 is slidably connected inside the guide groove 33. A connecting sleeve 31 located on the side away from the turntable 35 is fixedly connected to the end of the moving rod 310 away from the guide rod 32. A moving groove 311 is opened inside the moving rod 310. The end of the fixing block 318 away from the belt 37 is fixedly connected to the inner wall of the moving rod 310. A blocking block 313 is fixedly connected inside the guide rod 32. The blocking block 313 is on the movement trajectory of the fixing block 318. The blocking block 313 and the rotating rod 38 below it slide in the moving groove 311. Locking holes 314 are evenly opened on the outer wall of the moving rod 310. A concave block 315 is fixedly connected to the end of the guide rod 32 away from the turntable 35. A cylinder 316 is fixedly connected inside the concave block 315. A locking rod 317 is rotatably connected to the surface of the cylinder 316. The shape and size of the end of the locking rod 317 away from the cylinder 316 match the shape and size of the locking hole 314.

[0045] Specifically: the fixed block 318 is designed to move the moving rod 310 along with the guide belt 312; the blocking block 313 prevents the fixed block 318 from sliding down with the guide belt 312 and prevents the moving rod 310 from moving to the furthest distance away from the turntable 35; the locking hole 314 and locking rod 317 prevent the moving rod 310 from sliding when it moves to the required width of the student bed away from the turntable 35; the guide rod 32 has a square slot at one end near the turntable 35, and the guide groove 33 is connected to the square slot in the guide rod 32. The square slot in the guide rod 32 prevents the moving rod 310 from sliding when it moves to the furthest distance near the turntable 35.

[0046] Even better: Since the fixed block 318 is fixed on the guide belt 312 and the end of the fixed block 318 away from the guide belt 312 is fixed to the moving rod 310, the guide belt 312 moves along with the fixed block 318 during the displacement process, which in turn moves the moving rod 310. As the fixed block 318 moves with the guide belt 312 and moves the moving rod 310 away from the turntable 35, the fixed block 318 will move along with the guide belt 312. When the guide belt 312 moves to the end of the guide belt 312 away from the turntable 35, the fixed block 318 fixed on the guide belt 312 will abut against the blocking block 313, so that the moving rod 310 remains stationary when the fixed block 318 abuts against the blocking block 313. At this time, the moving rod 310 moves to the farthest distance away from the turntable 35.

[0047] When the operator moves the moving rod 310 away from the turntable 35 to the required width of the student bed by rotating the turntable 35, the operator stops rotating the turntable 35 and rotates the locking rod 317, which is rotatably connected to the cylinder 316, away from the turntable 35, so that the bottom of the locking rod 317 is inserted into the locking hole 314 opened on the moving rod 310, thereby preventing the moving rod 310 from sliding.

[0048] When the operator moves the moving rod 310 toward the turntable 35 by rotating the turntable 35 in the opposite direction, the end of the moving rod 310 near the turntable 35 abuts against the end of the square slot in the guide rod 32 near the guide groove 33, so that the moving rod 310 no longer slides.

[0049] The working principle of the above implementation is as follows:

[0050] The initialization steps are as follows:

[0051] The operator presses multiple fasteners 21 against the wall to make them adhere to the wall, and fixes the crossbar 1 to the end of the multiple fasteners 21 away from the wall. At this time, the connecting sleeve 31 is in the middle of the crossbar 1, and the turntable 35 is located between the crossbar 1 and the wall.

[0052] The operation steps are as follows:

[0053] like Figures 1 to 8As shown, the operator rotates the turntable 35, causing the bevel gear rod 34 fixed on the turntable 35 to rotate. The rotation of the bevel gear rod 34 drives the bevel gear at the end of the turntable 35 away from the turntable 35 to rotate, which in turn rotates with the bevel gear fixed on the rotating rod 36. This causes the rotating rod 36 inside the guide rod 32 to rotate. During rotation, the rotating rod 36 causes the belt 37 on it to start driving, which in turn drives the rotating rod 38 closer to the turntable 35. The rotating rod 38 closer to the turntable 35, driven by the belt 37, begins to rotate inside the guide groove 33, causing the collar 39 fixed on the rotating rod 38 closer to the turntable 35 to rotate. As the rotating rod 38 near the turntable 35 rotates, it drives the guide belt 312 on the collar 39 near the turntable 35. During the transmission of the guide belt 312, the collar 39 on the rotating rod 38 away from the turntable 35 rotates. The rotating collar 39 on the side away from the turntable 35 drives the rotating rod 38 fixed thereto to rotate. Since the outer wall of the guide belt 312 is fixed to the fixed block 318 and the end of the fixed block 318 away from the guide belt 312 is fixed to the inner wall of the moving rod 310, the moving rod 310 moves together with the guide belt 312 under the fixation of the fixed block 318.

[0054] During the displacement of the moving rod 310, when the moving rod 310 moves away from the turntable 35, the fixed block 318 fixed on the guide belt 312 moves away from the turntable 35 via the guide belt 312, causing the moving rod 310 to move together with the guide belt 312. During this process, the moving groove 311 will slide past the blocking block 313 and the rotating rod 38 on the side away from the turntable 35 until the fixed block 318 and the blocking block 313 come into contact. At this time, the moving rod 310 moves to the farthest distance away from the turntable 35. Because the fixed block 318 and the blocking block 313 come into contact, the guide belt 312 fixed to the fixed block 318 no longer moves. At this time, the moving rod 310, which moves with the guide belt 312, stops moving and moves to the farthest distance away from the turntable 35. At this time, the operator stops rotating the turntable 35. The cessation of rotation of rod 5 keeps the bevel gear rod 34, rotating rod 36, belt 37, rotating rod 38, and collar 39 stationary. As the moving rod 310 begins to move away from the turntable 35 until the fixed block 318 is blocked by the blocking block 313, the operator rotates the turntable 35 to move the moving rod 310 away from the turntable 35 until it reaches the same width as the required student bed. The operator then stops rotating the turntable 35 and uses the cylinder 316 fixed on the concave block 315 at the end of the guide rod 32 away from the turntable 35 to rotate the locking rod 317 rotating on the cylinder 316 away from the turntable 35, causing the locking rod 317 to abut against the lock hole 314. Because the shape and size of the end of the locking rod 317 away from the cylinder 316 match the shape and size of the lock hole 314, the locking rod 317 is inserted into the lock hole 314, preventing the moving rod 310 from sliding.

[0055] When the moving rod 310 moves towards the side closer to the turntable 35, the operator rotates the turntable 35 in the opposite direction. The reverse rotation of the turntable 35 causes the belt 37 to move towards the turntable 35, causing the moving rod 310, which is fixed to the fixed block 318, to move towards the turntable 35 together. Since the guide rod 32 has a square slot at one end near the turntable 35, and the guide groove 33 is connected to the square slot in the guide rod 32, when the end of the moving rod 310 near the turntable 35 abuts against the end of the square slot in the guide rod 32 near the guide groove 33, the moving rod 310 retracts to its shortest state in the guide groove 33 towards the turntable 35.

[0056] like Figures 1 to 3 , Figures 9 to 10As shown, because the fixing device 21 is evenly fixedly connected to the crossbar 1, the column rod 22 is fixed to the connecting column 11 near the turntable 35, and the telescopic rod 24 is fixed to the connecting column 11 away from the turntable 35, when the moving rod 310 moves, because the end of the moving rod 310 away from the turntable 35 is fixed to the connecting sleeve 31 away from the turntable 35, the moving rod 310 will drive the crossbar 1, which is connected to it and away from the turntable 35, to move together through the connecting sleeve 31 away from the turntable 35. Then, through the connecting column 11 fixed to the crossbar 1, the telescopic rod 24 will move together with the moving rod 310. The displacement of the telescopic rod 24 causes the telescopic rod 24 to slide inside the slide groove 23, thereby achieving the effect of moving together with the moving rod 310.

[0057] By evenly fixing the device to the crossbar 1 with the fastener 21 and adhering it to the wall, the privacy-protecting student bed isolation device can be installed without the support frame around the student bed. This avoids the problem of having to splice the support rods and insert them one by one around the student bed during the installation of the existing privacy-protecting student bed isolation device with the bed canopy frame. This ensures that the installation process of the privacy-protecting student bed isolation device is simple for the operator.

[0058] By sliding the telescopic rod 24 inside the slide groove 23 together with the moving rod 310, it is ensured that the operator can adjust the width of the student bed isolation device with privacy protection function according to the required width of the student bed when using it. This avoids the problem that the bed canopy frame in the existing student bed isolation device with privacy protection function can only be adapted to student beds with the same width, making it impossible for student beds with different widths to use the bed canopy frame in the existing student bed isolation device with privacy protection function. This ensures the versatility of the student bed isolation device with privacy protection function.
