Description

Technical Field

[0001] This utility model relates to the field of gas springs for concealed beds, specifically a gas spring for concealed beds. Background Technology

[0002] Even a small house needs all the essentials; a bed is the most basic requirement. Traditional beds, made of wood, are bulky, heavy, and difficult to move. Clearly, for a small house, such beds waste a lot of space. While folding beds are small and easy to move, their stability and comfort are poor, making them unsuitable for long-term sleeping. To make the most of every inch of space in a small house, a hidden bed has emerged. It offers the comfort of a traditional bed while folding away and hiding in the wall, saving space and gaining popularity. For hidden beds, gas springs are key to supporting and extending the entire bed.

[0003] Traditional gas springs used in concealed beds require disassembly and repositioning after installation if the extension length is insufficient. This inefficiency affects the adjustment efficiency. Furthermore, the gas spring's operation, based on the expansion and contraction of gas to control movement, makes its internal structure relatively fragile. Excessive force during folding of the concealed bed can easily damage the gas spring, shortening its lifespan. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a gas spring for a concealed bed. This solves the technical problem that when the gas spring is installed and its extension length is insufficient, personnel need to disassemble the gas spring from the bed to adjust its position, which affects the efficiency of adjusting the extension length of the gas spring.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a gas spring for a concealed bed is designed, including a cylinder, a piston rod is provided at one end of the cylinder, a connecting block is installed at the end of the cylinder away from the piston rod, a sliding rod and a screw are respectively provided on both sides of one end of the connecting block, the sliding rod is fixedly connected to the connecting block, the screw is rotatably connected to the connecting block, an adjusting plate is sleeved between the outer sides of the sliding rod and the screw, the sliding rod is slidably connected to the adjusting plate, the adjusting plate is threadedly connected to the screw, a connecting plate is connected to the adjusting plate through a connecting rod, a first mounting ear is installed at one end of the connecting plate, and a second mounting ear is provided at one end of the piston rod.

[0006] Preferably, a mounting plate is installed between the piston rod and the second mounting lug, and a buffer spring is sleeved on the outer side of the piston rod, with the two ends of the buffer spring connected to the cylinder and the mounting plate, respectively.

[0007] Preferably, a protective cylinder is installed on the outside of the mounting plate, the internal dimensions of the protective cylinder are adapted to the external dimensions of the cylinder, and the length of the protective cylinder is adapted to the length of the cylinder.

[0008] Preferably, a drive disk is mounted on the end of the screw, and the drive disk is hexagonal.

[0009] Preferably, a limiting plate is installed at the end of the slide rod, and the limiting plate is circular.

[0010] Preferably, the length of the slide bar is the same as the length of the screw, and the slide bar and the screw are symmetrically distributed on the connecting block.

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

[0012] 1. This utility model combines a cylinder, connecting block, slide rod, screw, adjusting plate, first mounting ear, piston rod, and second mounting ear. By turning the screw in conjunction with the slide rod to guide the adjusting plate, the distance between the first mounting ear and the cylinder is increased, thereby increasing the overall length of the gas spring. This further ensures that the bed can be opened and placed on the support surface when the gas spring extends or retracts, eliminating the need for personnel to disassemble and adjust the gas spring after installation, and further improving the efficiency of the installation of the concealed bed.

[0013] 2. The buffer spring in this utility model is designed so that when the folding force of the concealed bed is too large, the buffer spring is compressed, thereby converting the impact force of folding the concealed bed into the deformation of the buffer spring. This effectively avoids damage to the gas spring caused by excessive folding force of the concealed bed and further extends the service life of the gas spring.

[0014] 2. This utility model, through the setting of the protective cylinder, moves with the piston rod when it extends or retracts. When the piston rod is extended, the protective cylinder shields the buffer spring and the piston rod, not only preventing the buffer spring from being exposed on the outside and causing pinching injuries to personnel, but also protecting the piston rod and extending its service life. When the piston rod is folded, the protective cylinder is sleeved on the outside of the cylinder, thereby protecting the cylinder and further extending its service life. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0019] Example 1: A gas spring for a concealed bed, see [link / reference] Figures 1 to 2 The system includes a cylinder 1, with a piston rod 12 at one end and a connecting block 2 at the end of the cylinder 1 away from the piston rod 12. A sliding rod 21 and a screw 24 are respectively provided on both sides of one end of the connecting block 2. The sliding rod 21 is fixedly connected to the connecting block 2, and the screw 24 is rotatably connected to the connecting block 2. An adjusting plate 23 is sleeved between the outer sides of the sliding rod 21 and the screw 24, and the sliding rod 21 is slidably connected to the adjusting plate 23. The adjusting plate 23 is threadedly connected to the screw 24. A connecting plate 26 is connected to the adjusting plate 23 via a connecting rod. A first mounting lug 27 is installed at one end of the connecting plate 26. One end of the piston rod 12 is provided with a second mounting ear 11. During operation, the gas spring is installed between the fixed surface and the headboard via the first mounting ear 27 and the second mounting ear 11. When the gas spring is installed and adjusted, if the extension and retraction of the piston rod 12 cannot fully support the bed on the ground, the screw 24 is turned in conjunction with the slide rod 21 to guide the adjusting plate 23, thereby increasing the distance between the first mounting ear 27 and the cylinder 1, and thus increasing the overall length of the gas spring. This further ensures that the gas spring can fully support the bed on the support surface when it extends and retracts, thus eliminating the need for personnel to disassemble and adjust the installed gas spring, and further improving the efficiency of the concealed bed installation.

[0020] For details, see Figure 2 A mounting plate 13 is installed between the piston rod 12 and the second mounting ear 11. A buffer spring 3 is sleeved on the outside of the piston rod 12. The two ends of the buffer spring 3 are connected to the cylinder 1 and the mounting plate 13 respectively. By setting the buffer spring 3, when the folding force of the concealed bed is too large, the buffer spring 3 is compressed, thereby converting the impact force of folding the concealed bed into the deformation of the buffer spring 3. This can effectively prevent the excessive folding force of the concealed bed from damaging the gas spring and further extend the service life of the gas spring.

[0021] Further, see Figure 1A protective cylinder is installed on the outside of the mounting plate 13. The internal dimensions of the protective cylinder are adapted to the external dimensions of the cylinder 1, and the length of the protective cylinder is adapted to the length of the cylinder 1. With the setting of the protective cylinder, when the piston rod 12 extends or retracts, the protective cylinder moves with the piston rod 12. When the piston rod 12 is extended, the protective cylinder shields the buffer spring 3 and the piston rod 12, which not only prevents the buffer spring 3 from being exposed on the outside and causing injury to personnel, but also protects the piston rod 12 and extends the service life of the piston rod 12. When the piston rod 12 is folded, the protective cylinder is sleeved on the outside of the cylinder 1, thereby protecting the cylinder 1 and further extending the service life of the cylinder 1.

[0022] It is worth noting that, see Figure 1 The end of the screw 24 is equipped with a drive disc 25, which is hexagonal. The end of the slide rod 21 is equipped with a limiting disc 22, which is circular. The length of the slide rod 21 is the same as the length of the screw 24. The slide rod 21 and the screw 24 are symmetrically distributed on the connecting block 2. The hexagonal drive disc 25 facilitates the connection between the screw 24 and the screw 24 by a wrench, thereby facilitating the adjustment of the overall length of the gas spring by rotating the screw 24. The cooperation between the limiting disc 22 and the drive disc 25 can prevent the adjusting plate 23 from detaching from the slide rod 21 and the screw 24, thus avoiding affecting the installation of the gas spring.
