[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0031] like Figures 1 to 5As shown, this embodiment of the utility model provides a folding guardrail, which includes a first guardrail arm 10, a second guardrail arm 20, a guardrail horizontal tube 30, and a locking member 40. The first guardrail arm 10 and the second guardrail arm 20 are spaced apart along a first transverse direction. Both the first guardrail arm 10 and the second guardrail arm 20 can be swayed and set on the hospital bed. The swing axis of the first guardrail arm 10 and the swing axis of the second guardrail arm 20 are both parallel to the second transverse direction, which is perpendicular to the first transverse direction. The extension direction of the guardrail horizontal tube 30 is parallel to the first transverse direction. One end of the guardrail horizontal tube 30 is hinged to the upper end of the first guardrail arm 10. The other end of the tube 30 is hinged to the upper end of the second guardrail arm 20. The hinge axis of the guardrail horizontal tube 30 and the first guardrail arm 10 is parallel to the second lateral direction. The locking member 40 is disposed between the guardrail horizontal tube 30 and the first guardrail arm 10. The locking member 40 has an unlocked state and a locked state. When the locking member 40 is in the locked state, the locking member 40 restricts the swing of the first guardrail arm 10 relative to the guardrail horizontal tube 30, and the guardrail horizontal tube 30 is at its highest height. When the locking member 40 is in the unlocked state, the locking member 40 allows the first guardrail arm 10 to swing relative to the guardrail horizontal tube 30.

[0032] The folding guardrail provided in this embodiment includes a first guardrail arm 10, a second guardrail arm 20, a guardrail horizontal tube 30, and a locking member 40. Since the first guardrail arm 10 and the second guardrail arm 20 are spaced apart along the first transverse direction, and the swing axis of the first guardrail arm 10 and the swing axis of the second guardrail arm 20 are both parallel to the second transverse direction, when the locking member 40 is in the unlocked state, both the first guardrail arm 10 and the second guardrail arm 20 can swing relative to the guardrail horizontal tube 30 to realize the raising and lowering of the guardrail horizontal tube 30 relative to the hospital bed, and realize the switching between the folding guardrail in the folded state and the unfolded state. When the folding guardrail is in the unfolded state, the guardrail horizontal tube 30 is at its highest height. Since one end of the guardrail horizontal tube 30 is hinged to the upper end of the first guardrail arm 10 and the other end of the guardrail horizontal tube 30 is hinged to the upper end of the second guardrail arm 20, and the locking member 40 is located between the guardrail horizontal tube 30 and the first guardrail arm 10, when the folding guardrail is switched to the folding state, there is no need to bend over to operate the locking member 40. The locking member 40 can be switched to the unlocked state while standing. Then, by moving the locking member 40, the guardrail horizontal tube 30 is moved, so that the first guardrail arm 10 and the second guardrail arm 20 swing relative to the guardrail horizontal tube 30. The guardrail horizontal tube 30 rises and falls to realize the folding and unfolding of the folding guardrail.

[0033] Therefore, the folding guardrail provided in this embodiment can switch the locking member 40 between the locked and unlocked states as needed, realizing the folding and unfolding of the folding guardrail. It can provide stable support when the patient needs protection, and can be easily folded when the caregiver needs to approach the patient, thus improving the flexibility and safety of the use of the hospital bed.

[0034] like Figure 2 As shown, the locking element 40 includes a grip 41, which is movably fitted onto the guardrail horizontal tube 30. When the grip 41 moves relative to the guardrail horizontal tube 30, it allows the locking element 40 to switch between a locked and unlocked state. This design allows the user to switch the locking element 40 between the locked and unlocked states by moving the grip 41. Furthermore, after the locking element 40 is switched to the unlocked state, the user can maintain the grip on the grip 41 and move it to move the guardrail horizontal tube 30, causing the first guardrail arm 10 and the second guardrail arm 20 to swing relative to the guardrail horizontal tube 30. The guardrail horizontal tube 30 then rises and falls to fold and unfold the folding guardrail. This simple and intuitive operation ensures that even under highly stressful circumstances, caregivers can quickly adjust the folding guardrail, avoiding time delays caused by complex operations. This is of great significance for improving emergency response efficiency and ensuring patient safety.

[0035] like Figure 2 and Figure 3 As shown, the locking member 40 also includes a locking pin 42, which is movably disposed on the guardrail horizontal tube 30 along the extension direction of the guardrail horizontal tube 30. The first guardrail arm 10 has a locking groove 11. When the locking member 40 is in the locked state, the locking pin 42 extends into the locking groove 11 so that the guardrail horizontal tube 30 and the first guardrail arm 10 are engaged in the upper limit of the swing direction of the first guardrail arm 10. When the locking member 40 is in the unlocked state, the locking pin 42 and the locking groove 11 are separated, and the gripping member 41 is driven to engage with the locking pin 42. When the gripping member 41 moves relative to the guardrail horizontal tube 30, the gripping member 41 can drive the locking pin 42 to move along the extension direction of the guardrail horizontal tube 30. When the locking member 40 is in the locked state, the locking pin 42 extends into the locking groove 11 so that the guardrail horizontal tube 30 and the first guardrail arm 10 are engaged in the upper limit of the swing direction of the first guardrail arm 10. The locking engagement of the locking pin 42 and the locking groove 11 helps to improve the locking reliability of the locking member 40.

[0036] like Figures 2 to 5As shown, the gripper 41 is rotatably fitted onto the guardrail horizontal tube 30. A first limiting structure 50 is provided between the guardrail horizontal tube 30 and the gripper 41 to limit the position of the gripper 41 in the extending direction of the guardrail horizontal tube 30. The inner wall of the gripper 41 is provided with a transmission groove 411. The locking pin 42 has a transmission protrusion 421, which extends movably into the transmission groove 411 along its extending direction. A second limiting structure 60 extending along the extending direction of the guardrail horizontal tube 30 is provided between the guardrail horizontal tube 30 and the locking pin 42. When the gripper 41 rotates relative to the guardrail horizontal tube 30, the gripper 41 can drive the transmission protrusion 421 to move along the extending direction of the guardrail horizontal tube 30 through the transmission groove 411. By using the first limiting structure 50 and the second limiting structure 60, the accidental movement of the gripper 41 and the locking pin 42 in the non-operating state can be effectively prevented, ensuring the stability of the guardrail during use.

[0037] Furthermore, the position of the locking pin 42 can be adjusted by rotating the grip 41, which is simple and intuitive to operate. Even at night with insufficient light, caregivers can quickly and accurately adjust the guardrail, improving the safety and efficiency of nighttime care. It also reduces unnecessary movement and light interference, providing patients with a quieter and more comfortable resting environment, which helps patients recover at night and improves their sleep quality.

[0038] like Figures 2 to 4 As shown, the first limiting structure 50 includes a limiting protrusion 51 and a limiting groove 52. The limiting protrusion 51 is disposed on one of the guardrail horizontal tube 30 and the grip 41. The limiting groove 52 extends along the circumferential direction of the guardrail horizontal tube 30 and is disposed on the other of the guardrail horizontal tube 30 and the grip 41. The limiting protrusion 51 extends rotatably into the limiting groove 52 about the axis of the guardrail horizontal tube 30. By using the above-mentioned limiting protrusion 51 and limiting groove 52, the transmission reliability between the grip 41 and the locking pin 42 can be improved, and the movement of the locking pin 42 caused by accidental collisions or unintentional actions of the patient can be avoided, ensuring the safety of the patient. At the same time, it also reduces the time that nursing staff spend maintaining and inspecting the equipment, thus improving work efficiency.

[0039] like Figure 2 and Figure 3As shown, the locking pin 42 is disposed within the inner hole of the guardrail horizontal tube 30. The second limiting structure 60 includes a strip-shaped hole 61, which is disposed on the side wall of the guardrail horizontal tube 30 and communicates with the inner hole. The extension direction of the strip-shaped hole 61 extends along the first transverse direction. The transmission protrusion 421 is movably inserted through the strip-shaped hole 61 along the extension direction of the strip-shaped hole 61. The use of the strip-shaped hole 61 improves the stability of the movement of the locking pin 42 and prevents movement of the locking pin 42 due to accidental collisions or unintentional actions by the patient, ensuring patient safety. It also reduces the time nursing staff spend maintaining and inspecting the equipment, improving work efficiency.

[0040] like Figure 4 As shown, a sensing protrusion 4111 is provided on the inner sidewall of the transmission groove 411. The sensing protrusion 4111 is located in the area of ​​the transmission groove 411 that protrudes towards the first guardrail arm 10. The transmission protrusion 421 can cooperate with the sensing protrusion 4111. By providing the sensing protrusion, the user can perceive the state of the locking member 40 by touch when rotating the grip 41, without visual confirmation, which improves the convenience of operation in various environments. Especially at night or in poorly lit wards, nursing staff can quickly adjust the guardrail by touch, reducing operational errors.

[0041] like Figure 4 As shown, the sensing protrusion 4111 includes two sensing protrusions 4112 spaced apart in the extending direction of the transmission groove 411. When the locking member 40 is in the locked state, the transmission protrusion 421 is located between the two sensing protrusions 4112 of the sensing protrusion 4111. With the above-mentioned two sensing protrusions 4112, when the locking member 40 is in the locked state, the transmission protrusion 421 is located between the two sensing protrusions 4112 of the sensing part, and the state of the locking member 40 can be sensed by the tactile sensation generated by the cooperation between the transmission protrusion 421 and the sensing protrusion 4112, regardless of whether the gripping member 41 is rotated forward or backward.

[0042] like Figures 2 to 5 As shown, the gripper 41 includes a grip sleeve 412, which is rotatably fitted onto the guardrail horizontal tube 30. A first limiting structure 50 is disposed between the grip sleeve 412 and the guardrail horizontal tube 30. The gripper 41 also includes two first reinforcing ribs 413, which are arranged parallel to each other on the inner sidewall of the grip sleeve 412 and spaced apart in the first transverse direction. The inner wall of the grip sleeve 412 and the two first reinforcing ribs 413 together form a transmission groove 411. By using the inner wall of the grip sleeve 412 and the two first reinforcing ribs 413 to form the transmission groove 411, the structure of the gripper 41 is made lighter, and the structural strength of the gripper 41 is improved by the first reinforcing ribs 413, ensuring durability under frequent operation and heavy pressure, and reducing maintenance and replacement costs due to insufficient structural strength.

[0043] like Figures 2 to 5 As shown, the gripper 41 includes a grip sleeve 412, which is rotatably fitted onto the guardrail horizontal tube 30. A first limiting structure 50 is disposed between the grip sleeve 412 and the guardrail horizontal tube 30. The gripper 41 also includes a second reinforcing rib 414 disposed on the inner sidewall of the grip sleeve 412, extending along the circumferential direction of the guardrail horizontal tube 30. By providing the second reinforcing rib 414, the weight reduction of the gripper 41 structure is improved, and the structural strength of the gripper 41 is increased, ensuring durability under frequent operation and heavy pressure, and reducing maintenance and replacement costs due to insufficient structural strength.

[0044] like Figure 2 , Figure 3 as well as Figure 5 As shown, the locking component 40 also includes a reset component 43, which is disposed between the locking pin 42 and the guardrail horizontal tube 30 to apply a reset force to the locking pin 42 in a direction closer to the first guardrail arm 10. By providing the reset component 43, the locking pin 42 can be automatically reset after being released in a non-operational state, avoiding the locking pin 42 from jamming due to improper operation and improving the stability of the folding guardrail in use.

[0045] like Figure 2 , Figure 3 as well as Figure 5 As shown, the locking pin 42 includes a pin body 422 and a positioning boss 423. The pin body 422 is movably mounted on the guardrail horizontal tube 30 along its extension direction. The positioning boss 423 is located in the middle of the pin body 422. A reset member 43 is sleeved on the pin body 422, located on the side of the positioning boss 423 opposite to the first guardrail arm 10. One end of the reset member 43 abuts against the positioning boss 423, and the other end of the reset member 43 is connected to the guardrail horizontal tube 30. The locking pin 42 with the above structure improves the smoothness of its movement and the accuracy of its reset, reduces instability during adjustment, and provides patients with a more comfortable and safer nursing experience.

[0046] like Figure 2 , Figure 3 as well as Figure 5 As shown, a first guide block 31 and a second guide block 32 are detachably provided in the inner hole of the guardrail horizontal tube 30. The first guide block 31 and the second guide block 32 are located on both sides of the positioning boss 423 in the first lateral direction. The pin 422 is movably disposed in the inner hole along the extension direction of the guardrail horizontal tube 30 and is movably inserted through the first guide block 31 and the second guide block 32 along the extension direction of the guardrail horizontal tube 30. By providing the first guide block 31 and the second guide block 32, the stability of the movement of the locking pin 42 is improved.

[0047] like Figure 2 As shown, the first guardrail arm 10 includes a first mounting base 12 and a first swing arm 13, and the second guardrail arm 20 includes a second mounting base 21 and a second swing arm 22. The first mounting base 12 and the second mounting base 21 are spaced apart on the hospital bed along a first transverse direction. The first swing arm 13 is swingably mounted on the first mounting base 12, and the second swing arm 22 is swingably mounted on the second mounting base 21. The swing axis of the first swing arm 13 and the swing axis of the second swing arm 22 are both parallel to the second transverse direction. Using the above-described first guardrail arm 10 and second guardrail arm 20, it is easy to install the folding guardrail onto the hospital bed.

[0048] Using the folding guardrail provided in this embodiment, only one hand is needed to rotate the grip sleeve 412 to switch the locking member 40 between the locked and unlocked states. Then, while holding the grip sleeve 41, the user moves the grip sleeve 41 to move the guardrail horizontal tube 30, causing the first guardrail arm 10 and the second guardrail arm 20 to swing relative to the guardrail horizontal tube 30. This not only allows for folding and unfolding of the guardrail while standing, but also ensures the stability of the folding guardrail in different usage states, greatly saving space, improving efficiency, and offering a simple structure and convenient use. Furthermore, the design considers user experience, making operation more intuitive and convenient, representing a practical and user-friendly improvement for both caregivers and patients.

[0049] In this embodiment, when the grip sleeve 412 is rotated, the locking pin 42 moves to the right and compresses the reset member 43 under the action of the transmission groove 411. When the grip sleeve 412 is rotated about 45°, the locking pin 42 completely disengages from the locking groove 11. When the grip sleeve 412 is released, the reset member 43 returns to its original state. The reset member 43 pushes the locking pin 42 to the left. At this time, the locking pin 42 forces the grip sleeve 412 to return to its original state through the transmission groove 411. When the locking pin 42 and the locking groove 11 are not aligned, the locking pin 42 cannot continue to move to the left and into the locking groove 11. At this time, the locking member 40 is still in the unlocked state, and the guardrail horizontal tube 30 can still move freely up and down. If the guardrail horizontal tube 30 continues to move upward until the locking pin 42 and the locking groove 11 are on the same horizontal line, the locking pin 42 and the locking groove 11 are aligned. Under the force of the reset member 43, the locking pin 42 is locked into the locking groove 11, and the grip sleeve 412 returns to its original position. At this time, the locking member 40 is in the locked state, and the guardrail horizontal tube 30 cannot continue to move up and down.

[0050] Another embodiment of this utility model provides a guardrail bed, which includes the folding guardrail described above. Using the guardrail bed provided in this embodiment, when the locking member 40 is in the unlocked state, both the first guardrail arm 10 and the second guardrail arm 20 can swing relative to the guardrail horizontal tube 30 to achieve the raising and lowering of the guardrail horizontal tube 30 relative to the hospital bed, realizing the switching between the folded and unfolded states of the folding guardrail. When the folding guardrail is in the folded state, the guardrail horizontal tube 30 is at its highest height. Since one end of the guardrail horizontal tube 30 is hinged to the upper end of the first guardrail arm 10 and the other end of the guardrail horizontal tube 30 is hinged to the upper end of the second guardrail arm 20, and the locking member 40 is located between the guardrail horizontal tube 30 and the first guardrail arm 10, when the folding guardrail is switched to the folding state, there is no need to bend over to operate the locking member 40. The locking member 40 can be switched to the unlocked state while standing. Then, by moving the locking member 40, the guardrail horizontal tube 30 is moved, so that the first guardrail arm 10 and the second guardrail arm 20 swing relative to the guardrail horizontal tube 30. The guardrail horizontal tube 30 rises and falls to realize the folding and unfolding of the folding guardrail.

In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0053] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0054] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0055] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0056] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
