The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0031] like Figures 1-4 As shown, this embodiment provides an adjustable anti-collision device for connecting the hospital bed 6 and the equipment cart 7.

[0032] The adjustable anti-collision device includes a telescopic rod assembly 1, a locking assembly 2, a universal assembly 3, and a gripping assembly 4. The telescopic rod assembly 1 includes a first telescopic rod 11 and a second telescopic rod 12. The first telescopic rod 11 has a telescopic channel along its extension direction. One end of the second telescopic rod 12 is inserted into the telescopic channel. By adjusting the insertion depth of the second telescopic rod 12 within the first telescopic rod 11, the overall length of the telescopic rod assembly 1 can be adjusted. Simultaneously, the locking assembly 2 is fitted at the junction of the first telescopic rod 11 and the second telescopic rod 12 to lock or release them, thus achieving both fixed and adjustable length of the telescopic rod assembly 1. Optionally, both the first telescopic rod 11 and the second telescopic rod 12 are elliptical cylindrical structures, so that the second telescopic rod 12 moves only along the extension direction of the first telescopic rod 11, avoiding relative rotation between them that could affect the use of the adjustable anti-collision device.

[0033] The gripper assembly 4 is connected to the universal joint assembly 3. The gripper assembly 4 can rotate through the universal joint assembly 3. Both the universal joint assembly 3 and the gripper assembly 4 include two units, with the two universal joint assemblies 3 and the two gripper assemblies 4 arranged in a one-to-one correspondence. One universal joint assembly 3 is connected to the free end of the first telescopic rod 11, and the other universal joint assembly 3 is connected to the free end of the second telescopic rod 12. The gripper assembly 4 is used to grip the hospital bed 6 or the equipment cart 7. Thus, the two gripper assemblies 4 can grip the hospital bed 6 and the equipment cart 7 respectively, and the gripping direction of the gripper assembly 4 can be adjusted through the universal joint assembly 3, making it convenient to use.

[0034] This adjustable anti-collision device, through the cooperation of the universal joint component 3 and the gripping hand component 4, can easily lock and grasp the hospital bed 6 and the equipment cart 7. Furthermore, by adjusting the length of the telescopic rod component 1, the hospital bed 6 and the equipment cart 7 can be kept at a suitable distance, thus preventing collisions caused by insufficient clearance between the hospital bed 6 and the equipment cart 7 during movement. This also prevents the life support equipment on the equipment cart 7 from malfunctioning and endangering the patient. Optionally, one, two, or more adjustable anti-collision devices can be installed between the hospital bed 6 and the equipment cart 7 to meet actual usage needs.

[0035] like Figure 2 and Figure 3 As shown, the gripper assembly 4 includes a gripper body 41, grippers 42, a knob 43, and a fastener 44. The gripper body 41 is connected to the universal joint 3, and the grippers 42 are hinged to the gripper body 41, allowing the grippers 42 to be selected relative to the gripper body 41. The knob 43 is threaded through the gripper body 41 and grippers 42 and connected to the fastener 44. By adjusting the knob 43 and the fastener 44, the distance between the gripper body 41 and grippers 42 can be adjusted and locked, facilitating the gripper body 41 and grippers 42 to clamp the railing of the hospital bed 6 or the frame of the equipment cart 7. Optionally, the gripper assembly 4 also includes a protective sleeve 46, which covers both the gripper body 41 and grippers 42. The protective sleeve 46 prevents the gripper body 41 and grippers 42 from making rigid contact with the hospital bed 6 or equipment cart 7, reducing wear and extending the service life of the adjustable anti-collision device. Alternatively, the protective sleeve 46 of the clamp 41 and the protective sleeve 46 of the gripper 42 are provided with anti-slip textures on opposite sides. The anti-slip textures can prevent the gripper assembly 4 from sliding relative to the bed 6 or the equipment cart 7, thereby avoiding collisions caused by sudden relative movement of the bed 6 and the equipment cart 7 during movement.

[0036] Meanwhile, the gripper assembly 4 also includes an elastic element 45. The two ends of the elastic element 45 are connected to the gripper body 41 and the gripper 42 respectively. The elastic element 45 makes the gripper 42 always have a tendency to move closer to the gripper body 41. Thus, when the gripper assembly 4 is used to grasp the hospital bed 6 or the equipment cart 7, after the medical staff manually pulls the gripper body 41 and the gripper 42 apart, the elastic element 45 can elastically pull the gripper 42, so that the gripper 42 automatically moves closer to the gripper body 41 to hold the hospital bed 6 or the equipment cart 7. This makes it convenient for the medical staff to adjust the knob 43 and the fastener 44 to lock the hospital bed 6 or the equipment cart 7.

[0037] Furthermore, the universal assembly 3 includes a universal ball sleeve 31, a universal connector 32, and a locking member 33. The universal ball sleeve 31 is connected to the free end of the first telescopic rod 11 or the second telescopic rod 12. The universal ball sleeve 31 has a universal ball groove. The ball head of the universal connector 32 is rotatably disposed within the universal ball groove. The connecting rod of the universal connector 32 is connected to the gripper assembly 4. Thus, through the cooperation of the universal ball sleeve 31 and the universal connector 32, the gripping angle of the gripper assembly 4 can be adjusted to facilitate the use of the adjustable anti-collision device. The locking member... The locking member 33 is threaded to the universal ball sleeve 31, and one end of the locking member 33 can pass through the universal ball sleeve 31 and abut against the ball head. Thus, when using the adjustable anti-collision device, the locking member 33 can be adjusted as needed. That is, when the ball head is locked by the locking member 33 to fix the relative position of the universal ball sleeve 31 and the universal connector 32, it can ensure that the hospital bed 6 and the equipment cart 7 are relatively stationary. When the ball head is released by the locking member 33 to allow the universal connector 32 to rotate relative to the universal ball sleeve 31, the relative position of the hospital bed 6 and the equipment cart 7 can be adjusted.

[0038] like Figure 2 and Figure 4 As shown, the locking assembly 2 includes a first locking cover 21, a second locking cover 22, a latching member 23, and a latching rod 24. One end of the first locking cover 21 is hinged to the second locking cover 22, allowing the first locking cover 21 to rotate relative to the second locking cover 22. This allows the first locking cover 21 and the second locking cover 22 to clamp or disengage the first telescopic rod 11 and the second telescopic rod 12. The latching member 23 is rotatably mounted on the first locking cover 21, and the latching rod 24 is mounted on the second locking cover 22. The latching member 23 can engage with the latching rod 24, bringing the first locking cover 21 and the second locking cover 22 closer together to lock the first telescopic rod 11 and the second telescopic rod 12, thereby fixing the first telescopic rod 11 and the second telescopic rod 12 and ensuring that the length of the telescopic rod assembly 1 does not change. Specifically, the latching member 23 has a C-shaped latch, through which it can engage with the latching rod 24.

[0039] Furthermore, the adjustable anti-collision device also includes a digital display rangefinder 5, which is mounted on the first telescopic rod 11. The rangefinder 5 measures and displays the length of the telescopic rod assembly 1, allowing medical personnel to view it in real time and preventing length changes in the telescopic rod assembly 1 due to the locking assembly 2 not locking the first telescopic rod 11 and the second telescopic rod 12, thus ensuring the functionality of the adjustable anti-collision device. Optionally, the second telescopic rod 12 is provided with a length indicator 121 along its extension direction. Through the interaction of the length indicator 121 and the digital display rangefinder 5, medical personnel can accurately and quickly adjust the telescopic rod assembly 1 to a preset length.

[0040] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
