Description

Technical Field

[0001] This utility model relates to the field of patient transport bed technology, and in particular to a retractable sunshade curtain for a patient transport bed. Background Technology

[0002] A patient transport bed is a specialized medical bed used for transferring patients between beds, from the operating table to the ward, and from an ambulance. The use of transport beds has solved the difficulties of transferring patients from the operating table to the ward after surgery. Transport beds are characterized by multi-position lifting and lowering, flexible movement, and ease of operation, changing the traditional methods of patient transfer and making the process more convenient and faster. This reduces the difficulties and pain for doctors and nurses when transferring patients, and minimizes the pain and hardship caused by traditional manual patient transfers. They are widely used in major hospitals and are essential medical equipment.

[0003] In the prior art, Chinese Patent No. CN216496093U discloses a protective device for a patient transport bed and a transport bed, which can conveniently protect patients during transport, provide sun and rain protection, reduce the risk of patient injury during transport, improve patient satisfaction, and is easy to install and store. It can be directly loaded and used on existing transport beds without modification. When producing new transport beds, this device can be directly integrated as part of the bed body, making it more convenient to use. However, in practical applications, there is still a problem that the existing patient transport bed sunshade curtain has a fixed relative distance from the bed board, and there is a large gap between the existing sunshade curtain and the bed board. This makes the sunshade curtain relatively high above the ground, and when the transport bed is moved, the sunshade curtain is prone to colliding with objects that are not easily seen at a high position, causing damage to the sunshade curtain. Therefore, we disclose a telescopic sunshade curtain for a patient transport bed. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a telescopic sunshade for a patient transport bed to solve the problem of the non-adjustable height of the sunshade.

[0005] To achieve the above objectives, this utility model provides a retractable sunshade curtain for a patient transport bed, comprising a transport bed body. Two first sleeves are rotatably connected to one side of the transport bed body, and two first fixing frames are fixedly connected to the other side of the transport bed body. A second sleeve is movably engaged in the middle of each of the first fixing frames. Support rods are slidably connected to the middle of both the second and first sleeves. A first connecting rod is rotatably connected to the top of each support rod. A sunshade curtain is fixedly connected between the two first connecting rods. The sunshade curtain is located above the transport bed body. Several first limiting grooves are formed in the middle of each support rod, and one end of the support rod... A first limiting rod is slidably engaged with the middle of the support rod. One end of the first limiting rod extends outside the support rod and passes through the outside of the first sleeve. A first spring is fixedly connected to the upper end of the first sleeve. A second limiting rod is slidably engaged with the middle of the other end of the support rod. A second connecting rod is fixedly connected to the end of the second limiting rod that extends out of the first limiting groove and passes through the outside of the second sleeve. A second spring is fixedly connected to one end of the second connecting rod. One end of the first spring is fixedly connected to the second connecting rod. The two ends of the second connecting rod are fixedly connected to the second limiting rod and the first limiting rod, respectively.

[0006] Preferably, the second limiting rod is sleeved inside the second spring, and the first limiting rod is sleeved in the middle of the first spring.

[0007] Preferably, a third spring is fixedly connected to one end of the first fixing frame, a third limiting rod is fixedly connected to one end of the third spring, a second limiting groove is provided at the lower end of the second sleeve, and one end of the third limiting rod that passes through the first fixing frame is movably engaged with the second limiting groove.

[0008] Preferably, the third limiting rod is T-shaped.

[0009] Preferably, a limiting ring is fixedly connected to the lower end of the second sleeve, and limiting frames are fixedly connected to both sides of the bottom end of the transfer bed body. The lower end of the second sleeve is movably sleeved with the limiting frame. Preferably, a hole is opened at one end of the limiting frame, and the diameter of the hole is smaller than the diameter of the limiting frame and larger than the diameter of the second sleeve.

[0010] Preferably, a third connecting rod is fixedly connected to both ends of the first connecting rod, and a connecting strap is fixedly connected to the outer wall of the third connecting rod. The third connecting rod is T-shaped.

[0011] The beneficial effects of this utility model are as follows: By restricting the rotational position of the first sleeve through the transfer bed body, the transfer bed body restricts the position of the second sleeve through the first fixed frame. The height of the support rod is restricted by the second sleeve and the first sleeve, thereby restricting the height of the first connecting rod and the sunshade curtain. This allows the height of the sunshade curtain to be adjusted when shading the sun, and the height of the sunshade curtain relative to the ground can be adjusted when the transfer bed body is moved, making it convenient for workers to move the transfer bed body and reducing the occurrence of collisions and damage to the sunshade curtain. Pulling the third limiting rod to move it out of the inner cavity of the first fixed frame, and then placing the second sleeve in the first fixed frame, releasing the pull on the third limiting rod allows the third limiting rod to return to its original position under the action of the third spring and engage with the second limiting groove, restricting the position of the second sleeve in the first fixed frame. This effectively restricts the position of the second sleeve, thereby stabilizing the position of the sunshade curtain. Furthermore, the sunshade curtain can be moved to one side of the transfer bed body when not needed, preventing the sunshade curtain from affecting the use of the transfer bed body.

[0020] like Figures 1-3As shown, a retractable sunshade for a patient transport bed includes a transport bed body 1. Two first sleeves 2 are rotatably connected to one side of the transport bed body 1, and two first fixing frames 3 are fixedly connected to the other side of the transport bed body 1. A second sleeve 4 is movably engaged in the middle of the first fixing frame 3. Support rods 5 are slidably connected to the middle of both the second sleeve 4 and the first sleeve 2. A first connecting rod 6 is rotatably connected to the top of the support rod 5. A sunshade 7 is fixedly connected between the two first connecting rods 6. The sunshade 7 is located above the transport bed body 1. Several first limiting grooves 8 are opened in the middle of the support rod 5. A first limiting rod 9 is slidably engaged in the middle of one end of the support rod 5. One end of the first limiting rod 9 extends to the outside of the support rod 5 and passes through the outside of the first sleeve 2. A first spring 10 is fixedly connected to the upper end of a sleeve 2, and a second limiting rod 13 is slidably engaged with the middle of the support rod 5 at the other end. The second limiting rod 13 extends out of the first limiting groove 8 and passes through to the outside of the second sleeve 4, where a second connecting rod 11 is fixedly connected. A second spring 12 is fixedly connected to one end of the second connecting rod 11. One end of the first spring 10 is fixedly connected to the second connecting rod 11, and both ends of the second connecting rod 11 are fixedly connected to the second limiting rod 13 and the first limiting rod 9, respectively. The second limiting rod 13 is sleeved inside the second spring 12, and the first limiting rod 9 is sleeved in the middle of the first spring 10. In use, two first sleeves 2 are rotatably connected to one side of the transfer bed body 1, and two first limiting rods 13 are fixedly connected to the other side of the transfer bed body 1. A first fixed frame 3 has a second sleeve 4 movably engaged in its middle, restricting the rotational position of the first sleeve 2 by the transfer bed body 1. The first fixed frame 3 also restricts the position of the second sleeve 4. Support rods 5 are slidably connected to the middle of both the second sleeve 4 and the first sleeve 2. A first connecting rod 6 is rotatably connected to the top of each support rod 5. A sunshade curtain 7 is fixedly connected between the two first connecting rods 6, positioned above the transfer bed body 1. This restricts the height of the support rods 5 by the second sleeve 4 and the first sleeve 2, thereby limiting the height of the first connecting rod 6 and the sunshade curtain 7. The height of the sunshade curtain 7 can be adjusted for sunshade purposes, allowing the transfer bed body 1 to move with the sunshade curtain 7 positioned relative to the ground. The height is adjustable to facilitate the movement of the transfer bed body 1 by staff, reducing the risk of damage to the sunshade curtain 7 due to collisions. Several first limiting grooves 8 are provided in the middle of the support rod 5. A first limiting rod 9 is slidably engaged in the middle of one end of the support rod 5. The end of the first limiting rod 9 extending outside the support rod 5 passes through the outside of the first sleeve 2. A first spring 10 is fixedly connected to the upper end of the first sleeve 2. A second limiting rod 13 is slidably engaged in the middle of the other end of the support rod 5. The end of the second limiting rod 13 extending out of the first limiting groove 8 and passing through the outside of the second sleeve 4 is fixedly connected to a second connecting rod 11. A second spring 12 is fixedly connected to one end of the second connecting rod 11. One end of the first spring 10 is fixedly connected to the second connecting rod 11.The two ends of the second connecting rod 11 are fixedly connected to the second limiting rod 13 and the first limiting rod 9, respectively. When adjusting the height of the sunshade 7, pulling the second connecting rod 11 moves the first limiting rod 9 and the second limiting rod 13, disengaging them from the first limiting groove 8. Then, the support rod 5 is adjusted to a suitable height, and the pulling of the second connecting rod 11 is released, causing the first limiting rod 9 and the second limiting rod 13 to return to their original positions under the action of the first spring 10, thus limiting the adjusted height of the support rod 5.

[0021] As a preferred embodiment of this example, Figure 1 and Figure 3As shown, a third spring 16 is fixedly connected to one end of the first fixed frame 3, and a third limiting rod 17 is fixedly connected to one end of the third spring 16. A second limiting groove 18 is opened at the lower end of the second sleeve 4. One end of the third limiting rod 17, which passes through the first fixed frame 3, is movably engaged with the second limiting groove 18. The third limiting rod 17 is T-shaped. A limiting ring 19 is fixedly connected to the lower end of the second sleeve 4. Limiting frames 20 are fixedly connected to both sides of the bottom end of the transfer bed body 1. The lower end of the second sleeve 4 is movably engaged with the limiting frame 20. A hole is opened at one end of the limiting frame 20. The diameter of the hole is smaller than the diameter of the limiting frame 20 but larger than the diameter of the second sleeve 4. Both ends of the first connecting rod 6 are fixed. A third connecting rod 14 is fixedly connected to the first fixing frame 3. A connecting strap 15 is fixedly connected to the outer wall of the third connecting rod 14. The third connecting rod 14 is T-shaped and a third spring 16 is fixedly connected to one end of the first fixing frame 3. A third limiting rod 17 is fixedly connected to one end of the third spring 16. A second limiting groove 18 is opened at the lower end of the second sleeve 4. One end of the third limiting rod 17, which passes through the first fixing frame 3, is movably engaged with the second limiting groove 18, so that the third limiting rod 17 is pulled out of the inner cavity of the first fixing frame 3. Then, the second sleeve 4 is placed in the first fixing frame 3, and the pulling of the third limiting rod 17 is released, so that the third limiting rod 17 returns to its original position under the action of the third spring 16. The second sleeve 4 engages with the second limiting groove 18, restricting its position within the first fixed frame 3. This effectively limits the position of the second sleeve 4, thereby stabilizing the position of the sunshade 7. Furthermore, the sunshade 7 can be moved to one side of the transfer bed body 1 when not needed, preventing it from interfering with the use of the transfer bed body 1. The third limiting rod 17 is T-shaped for ease of use. A limiting ring 19 is fixedly connected to the lower end of the second sleeve 4. Limiting frames 20 are fixedly connected to both sides of the bottom of the transfer bed body 1. The lower end of the second sleeve 4 is movably sleeved with the limiting frame 20. One end of the limiting frame 20 has a hole with a diameter smaller than that of the limiting frame 20. The diameter of the first connecting rod 6 is greater than that of the second sleeve 4, so that after the second sleeve 4 is flipped to one side of the transfer bed body 1, it can be inserted into the limiting frame 20, thus restricting the position of the second sleeve 4. Both ends of the first connecting rod 6 are fixedly connected to the third connecting rod 14, and the outer wall of the third connecting rod 14 is fixedly connected to the connecting strap 15, so that the connecting strap 15 can be knotted and tied, thus fixing the relative position of the two first connecting rods 6, further fixing the position of the second sleeve 4 after it is placed on one side of the transfer bed body 1, reducing the situation where the sunshade 7 affects the use of the transfer bed body 1 when it is not in use. The third connecting rod 14 is T-shaped to prevent the connecting strap 15 from sliding.
