[0012] As a preferred embodiment, when the inner inclined surface is used to unlock the locking rod, the movable end of the torsion spring moves from the unlocking position side to the locking position side, which is connected to the center of rotation of the locking turntable by the fixed end.

[0013] After adopting the above technical solution, the effect of this utility model is as follows: The medical bed board locking device includes a bed board. At least two insertion rods are provided at the end of the bed frame. A sleeve corresponding to the position of the insertion rod is provided on the bed board. The insertion rod is inserted into the sleeve. A locking rod protrudes from the bed frame. A pressing part pressing against the bed frame and a locking part that locks against the vertical surface of the bed frame are provided at the bottom of the bed board. A locking turntable cooperating with the locking rod is rotatably mounted on the locking part. The locking turntable has an opening groove, one side of which is a locking position, and the other side is an unlocking position. A control knob controlling the rotation of the locking turntable to the locking or unlocking position is provided on the outer side of the bed board. A locking knob located at the locking position on the locking turntable is... The locking structure uses a locking lever. The inner side of the bed board has a fixed plate that blocks the locking turntable. The fixed plate has a notch for the locking lever to engage, which corresponds to an opening slot. The fixed plate also has a limiting structure that restricts the locking turntable's rotation to either the locking or unlocking position. The locking turntable itself has a retaining structure to maintain its position in either the locking or unlocking position. First, align the sleeve on the bed board with the insert rod and insert it. Simultaneously, manually turn the control knob to move the locking turntable to the unlocking position, where the locking lever engages in the opening slot. Then, turn the control knob again to move the locking turntable to the locking position to complete the locking. To unlock, simply turn the knob to the unlocking position and then pull up the bed board to complete disassembly. This device allows for locking of the bed board via a control knob, making it convenient and quick to use.

[0014] Furthermore, the locking structure includes a locking hook located at the locking position on the locking turntable, which cooperates with the locking rod. The locking turntable has an inner side at the unlocking position that cooperates with the locking rod to guide unlocking. In this way, the locking hook can hook the locking rod, thereby restricting the lifting and lowering movement of the bed board. Then, through the cooperation of the insert rod and the sleeve, it is simple and reliable. The inner side releases the constraint of the locking hook, so the bed board can be pulled out smoothly.

[0015] Furthermore, since the limiting structure includes an arc-shaped slot on the fixed plate, and the locking turntable is provided with a rotating column that is constrained in the arc-shaped slot when rotating, the rotating column is located at both ends of the arc-shaped slot and corresponds to the locking position and the unlocking position respectively; by the rotating column contacting both ends of the arc-shaped slot, it is ensured that the locking position and the unlocking position can be accurately positioned, and the locking turntable can be ensured to rotate accurately.

[0016] Furthermore, the retaining structure includes a torsion spring, which is located between the fixed plate and the locking turntable and is fitted inside the locking turntable. The fixed end of the torsion spring is fixedly installed on the fixed plate, and the movable end of the torsion spring is fixedly installed on the locking turntable. When the turntable is in the locking position, the movable end is located on one side of the line connecting the fixed end and the rotation center of the locking turntable. When the turntable is in the unlocking position, the movable end is located on the other side of the line connecting the fixed end and the rotation center of the locking turntable. The torsion spring can withstand the rotation of the locking turntable, ensuring that when the turntable is rotated to the unlocking or locking position, the torsion spring and the arc-shaped slot always maintain the corresponding position, facilitating manual assembly and disassembly.

[0017] Furthermore, a locking guide block is provided on the outside of the locking hook. The locking guide block has a locking guide slope that guides the locking rod into the locking hook when it is inserted. When the locking guide slope is in the locking position, it is located in the middle of the notch. When the locking guide slope is guiding, the movable end of the torsion spring is always located on the locking position side of the line connecting the fixed end and the rotation center of the locking turntable. In this way, when the bed board is directly aligned with the insertion rod and inserted, the locking guide slope of the locking guide block guides the locking rod, while the locking rod is restricted in the notch, forcing the locking turntable to rotate, thereby squeezing the locking rod into the opening groove inside the locking hook. At the same time, the torsion spring resets the locking turntable to the locking position, automatically completing the locking and improving the usage effect.

[0018] Furthermore, the locking turntable is equipped with an unlocking guide block at the unlocking station. The unlocking guide block has an unlocking guide slope that guides the locking rod into the opening groove during insertion. The inner side has an inner slope corresponding to the unlocking guide slope. The inner slope guides the locking rod to slide out and unlock. The unlocking guide slope is located in the middle of the notch when in the unlocking station. Therefore, when in the unlocking station, the locking rod can be guided and squeezed out by the inner slope to complete the unlocking. Alternatively, when the bed board is inserted at the unlocking station, the unlocking guide slope can also be squeezed and guided by the locking rod, causing the locking turntable to rotate and the locking rod to accurately enter the opening groove, thus improving the usage effect.

[0019] Furthermore, when the unlocking guide ramp is inserted into the guide, the movable end of the torsion spring moves from the unlocking position side to the locking position side, which is connected to the center of rotation of the locking turntable. Thus, when the bed board is inserted into the insert rod at the unlocking position, the locking rod squeezes the unlocking guide ramp into the opening groove, and the locking turntable automatically rotates to the locking position through the torsion spring, automatically locking and improving the usage effect.

[0020] Furthermore, when the inner inclined surface is used to unlock the locking rod, the movable end of the torsion spring moves from the unlocking position side to the locking position side along the line connecting the fixed end and the rotation center of the locking turntable. When the bed board is pulled out, the locking rod presses down on the inner inclined surface, thereby causing the locking turntable to rotate. The locking turntable automatically rotates to the locking position through the torsion spring and automatically locks, making the next installation convenient and quick. Attached Figure Description

[0029] The present invention will be further described in detail below through specific embodiments.

[0030] like Figures 1 to 6As shown, a locking device for a medical bed board 1 includes a bed board 1. At least two insertion rods 2 are provided at the ends of the bed frame 25. The bed board 1 has sleeves 3 corresponding to the positions of the insertion rods 2, and the insertion rods 2 are inserted into the sleeves 3. A locking rod 4 extends from the bed frame 25. The bottom of the bed board 1 has a pressing part 5 that presses against the bed frame 25 and a locking part 6 that engages with the vertical surface of the bed frame 25 for locking. A locking turntable 7, which cooperates with the locking rod 4, is rotatably mounted on the locking part 6. The locking turntable 7 has an opening groove 8, one side of which is a locking position. On the other side is the unlocking station. The outer side of the bed board 1 is provided with a control knob 9 for controlling the locking turntable 7 to rotate to the locking station or the unlocking station. The locking turntable 7 is provided with a locking structure that cooperates with the locking rod 4 at the locking station. The inner side of the bed board 1 is provided with a fixing plate 10 that covers the locking turntable 7. The fixing plate 10 is provided with a notch 11 for the locking rod 4 to be inserted. The notch 11 corresponds to the opening slot 8. The fixing plate 10 is provided with a limiting structure that limits the rotation of the locking turntable 7 to the locking station or the unlocking station. The locking turntable 7 is provided with a holding structure that keeps the locking turntable 7 in the locking station or the unlocking station.

[0031] In this embodiment, the locking structure includes a locking hook 12 located at the locking position on the locking turntable 7. The locking hook 12 cooperates with the locking rod 4. The locking turntable 7 is provided with an inner side 13 at the unlocking position to guide the unlocking of the locking rod 4. The locking hook 12 can hook the locking rod 4, restricting the lifting and lowering of the locking rod 4, thereby restricting the lifting and lowering movement of the bed board 1. With the cooperation of the insert rod 2 and the sleeve 3, it is simple and reliable. The inner side 13 can release the constraint of the locking hook 12, so that the bed board 1 can be pulled out smoothly.

[0032] like Figure 6 As shown, the limiting structure includes an arc-shaped slot 14 on the fixed plate 10. The locking turntable 7 is provided with a rotating column 15 that is constrained in the arc-shaped slot 14 when rotating. When the rotating column 15 is located at both ends of the arc-shaped slot 14, it corresponds to the locking position and the unlocking position respectively. When the locking turntable 7 rotates, it will drive the rotating column 15 to rotate. The rotating column 15 contacts both ends of the arc-shaped slot 14 to ensure that it can accurately position the locking position and the unlocking position, ensuring that the locking turntable 7 rotates accurately and preventing over-rotation.

[0033] like Figure 4 and Figure 5As shown, the retaining structure includes a torsion spring 16, which is located between the fixed plate 10 and the locking turntable 7 and is fitted inside the locking turntable 7. The fixed end 18 of the torsion spring 16 is fixedly installed on the fixed plate 10, and the movable end 19 of the torsion spring 16 is fixedly installed on the locking turntable 7. When the turntable is in the locking position, the movable end 19 is located on one side of the line connecting the fixed end 18 and the rotation center of the locking turntable 7. When the turntable is in the unlocking position, the movable end 19 is located on the other side of the line connecting the fixed end 18 and the rotation center of the locking turntable 7. The locking turntable 7 is provided with a mounting groove 17 for mounting the torsion spring 16. By rotating the locking turntable 7, the movable end 19 of the torsion spring 16 is controlled to rotate, ensuring that when the turntable is rotated to the unlocking or locking position, the torsion spring 16 releases its elastic force and cooperates with the arc-shaped slot 14 to always maintain the corresponding position, which is convenient for manual installation and removal.

[0034] like Figure 4 As shown, a locking guide block 20 is also provided on the outside of the locking hook 12. The locking guide block 20 is provided with a locking guide slope 21 that guides the locking rod 4 into the locking hook 12 when it is inserted. When the locking guide slope 21 is in the locking position, it is located in the middle of the notch 11. When the locking guide slope 21 guides, the movable end 19 of the torsion spring 16 is always located on the locking position side of the line connecting the fixed end 18 and the rotation center of the locking turntable 7. When the bed board 1 is directly aligned with the insertion rod 2 and inserted, the locking rod 4 is guided by the locking guide slope 21 of the locking guide block 20. At the same time, the locking rod 4 is restricted in the notch 11, which forces the locking turntable 7 to rotate, thereby squeezing the locking rod 4 into the opening groove 8 inside the locking hook 12. At the same time, the torsion spring 16 causes the locking turntable 7 to return to the locking position, automatically completing the locking. The locking is quick and improves the use effect.

[0035] like Figure 5 As shown, the locking turntable 7 is provided with an unlocking guide block 22 at the unlocking station. The unlocking guide block 22 is provided with an unlocking guide slope 23 that guides the locking rod 4 into the opening groove 8 when inserted. The inner side 13 is provided with an inner slope 24 corresponding to the unlocking guide slope 23. The inner slope 24 guides the locking rod 4 to slide out and unlock. When the unlocking guide slope 23 is in the middle of the notch 11 at the unlocking station, the locking rod 4 can be guided and squeezed out by the inner slope 24 to complete the unlocking. Alternatively, when the bed board 1 is inserted at the unlocking station, the unlocking guide slope 23 can also be squeezed and guided by the locking rod 4 to rotate the locking turntable 7 and accurately lock the locking rod 4 into the opening groove 8, improving the usage effect.

[0036] In this embodiment, when the unlocking guide ramp 23 is inserted into the guide, the movable end 19 of the torsion spring 16 moves from the unlocking position side to the locking position side of the line connecting the fixed end 18 and the rotation center of the locking turntable 7. In this way, when the bed board 1 is inserted into the insert rod 2 at the unlocking position, the locking rod 4 squeezes the unlocking guide ramp 23 into the opening groove 8, and the locking turntable 7 automatically rotates to the locking position through the torsion spring 16 and automatically locks, avoiding the need for manual turning of the control knob 9 and improving the usage effect.

[0037] Furthermore, when the inner inclined surface 24 guides the locking rod 4 to unlock, the movable end 19 of the torsion spring 16 moves from the unlocking position side of the line connecting the fixed end 18 and the rotation center of the locking turntable 7 to the locking position side; when the bed board 1 is pulled out, the locking rod 4 presses down on the inner inclined surface 24, thereby causing the locking turntable 7 to rotate. The locking turntable 7 automatically rotates to the locking position through the torsion spring 16 and automatically locks, making the next installation convenient and quick.

[0038] The working principle of this embodiment is as follows: First, the control knob 9 is manually rotated to the locking or unlocking position. Then, the insertion rod 2 is aligned and inserted through the sleeve 3 as a guide. When in the locking position, the locking rod 4 contacts the locking guide block 20, pressing the locking guide slope 21, causing the locking turntable 7 to rotate. The locking rod 4 is then inserted into the opening slot 8. Next, the torsion spring 16 drives the locking turntable 7 back to the locking position, and the locking hook 12 hooks the locking rod 4, completing the locking. When in the unlocking position, the locking rod 4 contacts the unlocking guide block 22, pressing the unlocking guide slope 23. After entering the opening slot 8, the locking turntable 7 automatically rotates to the locking position through the torsion spring 16, completing the locking. When it is necessary to remove the bed board 1, it is rotated to the unlocking position, and the locking rod 4 presses the inner slope 24 for guide extrusion, completing the unlocking.

[0039] The above-described embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Any modifications and alterations to the technical solution of the present utility model without departing from its design spirit shall fall within the protection scope defined by the claims of the present utility model.
