[0020] The present invention has the following advantages:
[0021] 1. The earthquake emergency life-saving bed provided by the present invention has a structure in which, when an earthquake occurs, the pendulum drives the vertical rod to swing. The vertical rod pulls the plug block out of the slot member via the upper pull rope, causing the rotating plate to rotate toward the bed body. After the rotating plate rotates, it can form a stable triangular support structure with the bed body and the support plate. Rolling stones are not easily accumulated on the rotating plate. At the same time, the earthquake emergency life-saving bed can respond to earthquakes without relying on electrical structures, and can be used for long-term standby, which is safe and reliable.
[0022] 2. The earthquake emergency life-saving bed provided by the present invention has a rotating plate slidably connected to a sliding plate. During the process of the rotating plate rotating toward the bed body, the sliding plate slides in a direction away from the first end of the rotating plate, and finally the sliding plate abuts against the bed body. The provision of the sliding plate can reduce the length requirement of the rotating plate, thereby preventing the bed body from overturning due to the rotating plate being too long.
[0023] 3. The earthquake emergency life-saving bed provided by the present invention has a sliding plate slidably arranged inside the rotating plate. The connection between the sliding plate and the rotating plate is not easy to accumulate dust, which can ensure that the structure can work normally under long-term standby conditions. The worm gear and the worm shaft can provide stable transmission. By flipping up the rotating plate under the cover, the sliding plate can be retracted into the rotating plate through the transmission relationship, which is convenient to use.
[0024] 4. In the earthquake emergency life-saving bed provided by the present invention, when an earthquake occurs, the cooperation between the ratchet teeth and the mixing piece prevents the rotating plate from accidentally opening, thereby further ensuring the safety of trapped persons.
[0025] 5. In the earthquake emergency life-saving bed provided by the present invention, the lower pull rope is connected to the rotating plate and the clamping block respectively, and the clamping block is simultaneously connected to the first clamping slot and the second clamping slot to fix the bed body and the bed board. When the rotating plate rotates, the lower pull rope drives the clamping block to slide out of the first clamping slot, and the bed board rotates relative to the bed body, and the trapped person slides into the bed body, where he can be further protected and awakened.
[0026] 6. In the earthquake emergency life-saving bed provided by the present invention, when the environment in which the trapped person is located deteriorates, the collapsed floor applies pressure to the rotating plate, allowing the rotating plate to continue rotating and eventually abut against the bed body. The provision of the safety assembly enables the rotating plate to rotate in stages, thereby preventing the rotating plate from accidentally injuring the trapped person and ensuring the stability of the interior space of the earthquake emergency life-saving bed.

[0037] Example
[0038] refer to Figure 1-Figure 3 The earthquake emergency life-saving bed provided by the embodiment of the present invention includes:
[0039] Bed 10;
[0040] The bed board 20 is connected to the bed body 10;
[0041] The support plate 30 is fixedly connected to one side of the bed body 10. The support plate 30 is located above the bed body 10 and is fixedly mounted with a fixed shaft 31. The axial direction of the fixed shaft 31 is consistent with the length direction or width direction of the bed body 10. A connecting portion is provided on the upper portion of the support plate 30. The connecting portion is rotatably connected to the first end of the vertical rod 70. The second end of the vertical rod 70 is fixedly connected to the pendulum 71.

[0043] The upper pull rope 50 has a first end connected to the vertical rod 70 and a second end connected to the insertion block 51. A locking portion is fixedly provided on the support plate 30, and a connecting groove 33 suitable for inserting the insertion block 51 is provided on the locking portion. The slot member 41 and the locking portion are suitable for being fixedly connected through the insertion block 51. The upper pull rope 50 is suitable for pulling the insertion block 51 out of the slot member 41 when the pendulum 71 swings, so that the rotating plate 40 rotates toward the bed body 10.
[0044] The support plate 30 is fixedly connected to one side of the bed body 10, and a rotating plate 40 is rotatably provided on the support plate 30. The upper part of the support plate 30 is rotatably connected to a vertical rod 70. One end of the vertical rod 70 is connected to a pendulum 71. An upper pull rope 50 is connected to the vertical rod 70. The other end of the upper pull rope 50 is connected to an insert block 51. The insert block 51 passes through the connecting groove 33 on the support plate 30 and is inserted into the slot member 41 of the rotating plate 40, thereby achieving a fixed connection between the support plate 30 and the rotating plate 40. When an earthquake occurs, the pendulum 71 drives the vertical rod 70 to swing, and the vertical rod 70 pulls the insert block 51 out of the slot member 41 through the upper pull rope 50, causing the rotating plate 40 to rotate toward the bed body 10. After the rotating plate 40 rotates, it can form a stable triangular support structure with the bed body 10 and the support plate 30 (which can abut against the wall). Rolling stones are not easily accumulated on the rotating plate 40. At the same time, the earthquake emergency life-saving bed provided by this embodiment can respond to earthquakes without relying on electrical structures, can be used for long-term standby, and is safe and reliable.
[0045] For further reference, Figure 2 The support plate 30 is provided with a reversing portion suitable for adjusting the pulling direction of the upper pull rope 50, which can be a reversing sleeve 32. The upper pull rope 50 is wound around the reversing sleeve 32 and then connected to the insert block 51.
[0046] In this embodiment, the structure of the bed body 10 is not specifically limited. It only needs to provide stable support for the bed board 20 during daily use. As an implementation method, it can be a square box structure. The length direction of the bed body 10 refers to the direction of the line connecting the head and the foot of the bed body 10, and the width direction refers to the direction of the line connecting the other two side ends of the bed body 10.
[0047] In this embodiment, the support plate 30 is fixedly connected to one side of the bed body 10. The connection position of the support plate 30 and the bed body 10 is not specifically limited here. As one embodiment, the support plate 30 is fixedly connected to the head of the bed, and the axial direction of the fixed axis 31 is consistent with the width direction of the bed body 10; as another embodiment, the support plate 30 is fixedly connected to a side wall adjacent to the head of the bed, and the axial direction of the fixed axis 31 is consistent with the length direction of the bed body 10. Furthermore, a baffle 11 is provided at at least one end of the head and foot of the bed body 10.
[0048] In this embodiment, the structure of the connecting portion is not specifically limited. After being connected to the vertical rod 70, the pendulum 71 can swing freely. As an embodiment, the connecting portion is a ball head 73, and a ball bowl 72 is fixedly provided at the first end of the vertical rod 70, and the ball head 73 is clamped in the ball bowl 72; as another embodiment, refer to Figure 2 The connecting portion is a ball bowl 72 , and a ball head 73 is fixedly provided on the first end of the vertical rod 70 , and the ball head 73 is snapped into the ball bowl 72 .
[0049] It should be noted that in this embodiment, the rotating plate 40 can abut against the bed 10 during the rotation process. The rotating plate 40 can directly abut against the bed 10, or the rotating plate 40 can be connected to other structures, and the rotating plate 40 cooperates with the structure to achieve abutment with the bed 10.
[0050] In a preferred embodiment, the rotating plate 40 is slidably connected to a sliding plate 42 . The sliding plate 42 is adapted to slide away from the first end of the rotating plate 40 and extend outward from the rotating plate 40 during the rotating plate 40 rotates toward the bed 10 .
[0051] In this embodiment, the rotating plate 40 is slidably connected to the sliding plate 42. During the process of the rotating plate 40 rotating toward the bed body 10, the sliding plate 42 slides in a direction away from the first end of the rotating plate 40, and finally the sliding plate 42 abuts against the bed body 10. The setting of the sliding plate 42 can reduce the length requirement of the rotating plate 40 (referring to the distance between the first end and the second end of the rotating plate 40), thereby preventing the rotating plate 40 from overturning the bed body 10 due to its excessive length.
[0052] In this embodiment, there is no specific limitation on the setting position of the sliding plate 42. It can be set on the side of the rotating plate 40 away from the bed body 10, or it can be set on the side of the rotating plate 40 facing the bed body 10. As a preferred embodiment, the rotating plate 40 is a hollow plate, and the sliding plate 42 is slidably set inside the rotating plate 40.
[0053] In this embodiment, the sliding plate 42 is slidably arranged inside the rotating plate 40. The connection between the sliding plate 42 and the rotating plate 40 is not easy to accumulate dust, which can ensure that the structure can still work normally under long-term standby conditions.
[0054] In this embodiment, the structure for achieving the sliding connection between the sliding plate 42 and the rotating plate 40 is not specifically limited. As an embodiment, the second end of the rotating plate 40 (i.e., the end opposite to the first end of the rotating plate 40) is provided with a groove, and the adapted sliding plate 42 is directly placed in the groove. During the rotation of the rotating plate 40 toward the bed body 10, the sliding plate 42 partially slides out of the groove by its own gravity; as another embodiment, reference is made to Figure 1 and Figure 2The rotating plate 40 is a hollow plate, and the sliding plate 42 is slidably arranged in the rotating plate 40. A through hole is provided at the first end of the rotating plate 40, and a threaded hole is opened on the first end of the sliding plate 42. The first end of the sliding plate 42 faces the first end of the rotating plate 40, and a threaded rod 43 adapted to the threaded hole partially passes through the through hole of the rotating plate 40 and is threadedly connected to the sliding plate 42. A worm gear 431 is fixedly provided at one end of the threaded rod 43 away from the second end of the rotating plate 40. The fixed shaft 31 is a worm shaft adapted to the worm gear 431, and the worm gear 431 is engaged with the worm shaft. The worm gear 431 is suitable for driving the threaded rod 43 to rotate when the rotating plate 40 rotates toward the bed body 10, so that the sliding plate 42 is rotated out in a direction away from the first end of the rotating plate 40.
[0055] In this embodiment, the threaded rod 43 partially passes through the rotating plate 40 and is threadedly connected to the sliding plate 42. A worm gear 431 is fixedly provided at one end of the threaded rod 43 away from the second end of the rotating plate 40. The fixed shaft 31 is a worm shaft adapted to the worm gear 431. The worm gear 431 engages with the worm shaft. When the rotating plate 40 rotates toward the bed body 10, the threaded rod 43 with the worm gear 431 rotates, causing the sliding plate 42 to be rotated out in the direction away from the first end of the rotating plate 40. This structure can provide stable transmission, and by flipping up the rotating plate 40 under the cover again, the sliding plate 42 can be retracted into the rotating plate 40 based on the transmission relationship, which is convenient to use.
[0056] Based on the above embodiment, in a preferred embodiment, reference Figure 2 A number of ratchet teeth 44 with the same rotation direction are evenly arranged on the rotating part, and a mixing piece 34 is slidably provided on the support plate 30. A first elastic piece 341 is connected between the support plate 30 and the mixing piece 34. The first elastic piece 341 is suitable for making the mixing piece 34 be stuck between the two ratchet teeth 44 to prevent the rotating plate 40 from rotating away from the bed body 10. An operating rod 342 is connected to the mixing piece 34, and the operating rod 342 is suitable for controlling the operating rod 342 to disengage from the ratchet teeth 44.
[0057] In this embodiment, when the rotating plate 40 rotates toward the bed body 10, the ratchet teeth 44 can push the mixing piece 34 away, so that the rotating plate 40 can be smoothly covered. When the rotating plate 40 rotates away from the bed body 10, it is necessary to use the operating rod 342 to disengage the mixing piece 34 from between the two ratchet teeth 44, otherwise the rotating plate 40 cannot be rotated. When an earthquake occurs, the cooperation between the ratchet teeth 44 and the mixing piece 34 prevents the rotating plate 40 from accidentally opening, further ensuring the safety of trapped people.
[0058] In this embodiment, the structure of the first elastic member 341 is not specifically limited. As an embodiment, it can be a compression spring. For details, refer to Figure 2A blind groove is provided on the support plate 30 below the ratchet teeth 44, and a compression spring is placed in the blind groove. A mixing piece 34 is provided above the compression spring, and the compression spring is suitable for pushing the mixing piece 34 into between the two ratchet teeth 44. The side wall of the mixing piece 34 is connected to an operating rod 342, which extends from the support plate 30 toward one end of the bed body 10. The connection between the mixing piece 34 and the ratchet teeth 44 can be disconnected by pressing down the operating rod 342.
[0059] In this embodiment, the connection between the bed board 20 and the bed body 10 is not specifically limited. As one embodiment, the bed board 20 is fixedly connected to the bed body 10. As another embodiment, the first end of the bed board 20 is rotatably connected to the upper part of the first end of the bed body 10, and the second end of the bed board 20 faces the second end of the bed body 10. The second end of the bed board 20 is provided with a first card slot 21, and the second end of the bed body 10 is provided with a second card slot 12, and the second card slot 12 is opposite to the first card slot 21. The bed board 20 and the support plate 30 are connected through a card block 61, and the first end of the card block 61 faces the first card slot 21, and the second end of the card block 61 faces away from the first card slot 21. A lower pull rope 60 is connected between the second end of the card block 61 and the rotating plate 40, and the lower pull rope 60 is suitable for driving the card block 61 to slide out of the first card slot 21 when the rotating plate 40 rotates toward the bed body 10.
[0060] In this embodiment, the pull-down rope 60 is connected to the rotating plate 40 and the block 61 respectively, and the block 61 is connected to the first slot 21 and the second slot 12 at the same time to fix the bed body 10 and the bed board 20, wherein the bed body 10 is a square box-shaped structure with an open top. When the rotating plate 40 rotates, the pull-down rope 60 drives the block 61 to slide out of the first slot 21, and the bed board 20 rotates relative to the bed body 10. The trapped person slides into the bed body 10 and can be further protected and awakened.
[0061] Furthermore, a reversing portion suitable for adjusting the pulling direction of the lower pull rope 60 is provided on the support plate 30 and / or the bed body 10 , and specifically may be a fixed pulley 35 .
[0062] In this embodiment, the structure of the second card slot 12 is not specifically limited. As an embodiment, it can be a through slot, and the card block 61 passes through the second card slot 12 and is engaged with the first card slot 21. As another embodiment, refer to Figure 3 The second card slot 12 is a blind slot, and the bottom of the second card slot 12 is provided with a through hole suitable for the lower pull rope 60 to pass through. The lower pull rope 60 can pull the card block 61 toward the bottom of the second card slot 12. At this time, the card block 61 is pulled out of the first card slot 21, and the bed board 20 rotates toward the bottom of the bed body 10.
[0063] Furthermore, a second elastic member 121 is connected between the block 61 and the second slot 12. The second elastic member 121 is suitable for pushing the block 61 into the first slot 21. Specifically, the second elastic member 121 can be a compression spring, one end of which abuts against the bottom of the second slot 12 and the other end abuts against the block 61. The provision of the second elastic member 121 can facilitate the resetting of the bed board 20. Figure 3 To reset, the lower pull cord 60 is pulled to completely retract the block 61 into the second slot 12. After the bed board 20 is reset, the lower pull cord 60 is released, and the block 61, under the action of the second elastic member 121, partially re-enters the first slot 21, completing the secure connection between the bed board 20 and the bed frame 10. Furthermore, the block 61 must overcome the force of the second elastic member 121 to operate, facilitating the daily use of the earthquake emergency life-saving bed.
[0064] Based on the above embodiment, in a preferred embodiment, a pull-down cord 60 is adapted to prevent the plane of the rotating plate 40 from abutting the bed 10 when the rotating plate 40 rotates toward the bed 10. One end of the pull-down cord 60 is connected to the rotating plate 40, and the other end is connected to the clamping block 61. By properly setting the length of the pull-down cord 60, the pull-down cord 60 can be gradually tightened in the early stages of the rotation of the rotating plate 40 toward the bed 10, ultimately restricting the rotating plate 40 from further rotation, preventing the rotating plate 40 from abutting the bed 10 immediately, and preventing the rotating plate 40 from causing damage to the limbs of the trapped person extending from the bed board 20.
[0065] It should be noted that the connection between one end of the lower pull rope 60 and the rotating plate 40 means that one end of the lower pull rope 60 is connected to the rotating plate 40, and it is sufficient to achieve a pulling effect on the lower pull rope 60 during the rotation of the rotating plate 40. It is not strictly limited to that one end of the rotating plate 40 needs to be fixed to the rotating plate 40. Figure 3 The end of the pull-down rope 60 may be wound around the fixed shaft 31 , and then connected to the clamping block 61 after passing through the rotating portion of the rotating plate 40 .
[0066] On the basis of the above embodiment, in a preferred embodiment, a safety component 62 is provided in the middle section of the pull-down rope 60 , and the safety component 62 is suitable for disconnecting when the tension of the pull-down rope 60 is too large.
[0067] In this embodiment, when the environment in which the trapped person is located deteriorates, the collapsed floor applies pressure to the rotating plate 40, so that the rotating plate 40 can continue to rotate and eventually abut against the bed body 10. The setting of the safety component 62 can enable the rotating plate 40 to rotate in stages, thereby avoiding accidental injury to the trapped person by the rotating plate 40 and ensuring the stability of the internal space of this embodiment.
[0068] In this embodiment, the structure of the safety component 62 is not specifically limited. As one embodiment, the safety component 62 can be a pair of magnets, each magnet is connected to an adjacent section of the pull-down rope 60; as another embodiment, the safety component 62 includes a first stress block 621 and a second stress block 622, and the first stress block 621 and the second stress block 622 are clamped together. When the tension of the pull-down rope 60 is too large, the first stress block 621 and the second stress block 622 are disconnected. Specifically, the stress block can be a wooden block.
[0069] Based on the above specific implementation, the working process of the earthquake emergency life-saving bed in this embodiment is as follows:
[0070] refer to Figure 1 After the earthquake occurs, the pendulum 71 drives the vertical rod 70 to swing, and the upper pull rope 50 connected to the vertical rod 70 pulls the plug 51 out of the slot member 41, and the rotating plate 40 starts to rotate around the fixed shaft 31. The worm gear 431 engaged with the fixed shaft 31 drives the threaded rod 43 to rotate, and the sliding plate 42 threadedly connected to the threaded rod 43 partially slides out of the rotating plate 40. At the same time, the lower pull rope 60 connected to the rotating plate 40 drives the card block 61 to be pulled out of the first card slot 21, and the bed board 20 rotates toward the bottom plate of the bed body 10. After the rotating plate 40 rotates a certain angle, the lower pull rope 60 is tightened and limits the rotating plate 40 from further rotation. After collapse occurs, the safety component 62 set in the middle section of the lower pull rope 60 is broken, and the rotating plate 40 continues to rotate, and finally the sliding plate 42 abuts against the bed body 10. Ratchet teeth 44 are arranged on the rotating part of the rotating plate 40. The ratchet teeth 44 cooperate with the mixing piece 34 provided on the support plate 30, so that the rotating plate 40 can only rotate in one direction without human interference, thereby preventing the rotating plate 40 from accidentally opening when the bed 10 overturns.
[0071] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
