[0029] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0031] like Figures 1 to 4 As shown, the present application provides a locking adjuster for an operating table screen frame, comprising a screen frame 2 and a locking device 1 for fixing the screen frame 2. The screen frame 2 comprises a fixing sleeve 21, a vertical rod 22 slidably connected to the fixing sleeve 21, and a transverse rod 23 provided on the vertical rod 22. A driving assembly 24 for adjusting the height of the vertical rod 22 is provided inside the screen frame 2.

[0032] The driving assembly 24 includes a screw rod 241 rotatably connected to the interior of the fixing sleeve 21 . The screw rod 241 is threadedly connected to the vertical rod 22 , and one end of the screw rod 241 extends to the outside of the fixing sleeve 21 .

[0033] In this embodiment, the locker 1 is first placed on the side rail of the operating bed, and then the fixing sleeve 21 is fixed by the locker 1. When the height of the screen frame 2 needs to be adjusted, the screw rod 241 is rotated. Since the screw rod 241 is threadedly connected to the vertical rod 22, and the vertical rod 22 is slidingly connected to the fixing sleeve 21, when the screw rod 241 is rotated, the vertical rod 22 moves up and down along the inside of the fixing sleeve 21, thereby driving the transverse rod 23 to move, so that the height of the transverse rod 23 and the vertical rod 22 is adjusted. Compared with the current adjustment method, it is more convenient and more efficient, and it also avoids the phenomenon of the screen frame 2 slipping during adjustment.

[0034] like Figure 2 As shown, the locker 1 includes a side rail connecting block 11 for connecting to the side rail of the operating bed, a first locking bolt 12 is threadedly connected to the lower end of the side rail connecting block 11, a connecting piece 13 is provided on one side of the side rail connecting block 11, the connecting piece 13 is used to connect to the fixing sleeve 21, the connecting piece 13 is columnar, and a mounting hole 14 is provided on the connecting piece 13 for the fixing sleeve 21 to pass through, a second locking bolt 15 is threadedly connected to one side of the connecting piece 13, and one end of the second locking bolt 15 extends to the inside of the mounting hole 14.

[0035] In this embodiment, the side rail connecting block 11 is first placed on the side rail of the operating bed, and after being moved to a suitable position, the first locking bolt 12 is screwed so that the first locking bolt 12 contacts the side rail, thereby fixing the position of the side rail connecting block 11. Subsequently, the fixing sleeve 21 is inserted into the mounting hole 14, and the second locking bolt 15 is screwed to fix the fixing sleeve 21, thereby realizing the installation of the screen frame 2 as a whole on the operating bed.

[0036] like Figure 2 As shown, a second tightening rod 151 is provided on the outer side of the second locking bolt 15 , and a first tightening rod 121 is provided on the outer side of the first locking bolt 12 .

[0037] In this embodiment, the second tightening rod 151 and the first tightening rod 121 are arranged so that the operator can more easily tighten the second locking bolt 15 and the first locking bolt 12 during operation.

[0038] like Figure 2 and Figure 3 As shown, the diameter of the mounting hole 14 is larger than the diameter of the fixing sleeve 21;

[0039] The outer side of the fixing sleeve 21 is provided with a positioning groove 212, and multiple groups of positioning grooves 212 are provided at equal intervals along the circumference of the fixing sleeve 21. The positioning grooves 212 are adapted to fit the second locking bolts 15.

[0040] A blocking piece 213 is provided on the outer side of the fixing sleeve 21 . The blocking piece 213 is arc-shaped and rotatably connected to the fixing sleeve 21 . The end face diameter of the blocking piece 213 is larger than the end face diameter of the connecting member 13 .

[0041] In this embodiment, after the fixing sleeve 21 is inserted into the mounting hole 14, the blocking piece 213 conflicts with the connecting piece 13 to prevent the fixing sleeve 21 from moving downward. Then, by screwing the second locking bolt 15, one end of the second locking bolt 15 is inserted into the positioning groove 212, so as to fix the fixing sleeve 21. The opening of the positioning groove 212 can prevent the second locking bolt 15 from causing squeezing damage to the outer wall of the fixing sleeve 21 when fixing the fixing sleeve 21. When it is necessary to adjust the rotation angle of the screen frame 2, the second locking bolt 15 is rotated to separate one end of the fixing sleeve 21 from the positioning groove 212, and then the fixing sleeve 21 can be directly rotated. After adjusting to the appropriate position, the second locking bolt 15 is tightened again to place one end of the fixing sleeve 21 in another set of positioning grooves 212. Under the obstruction of the blocking piece 213, the fixing sleeve 21 can be effectively prevented from slipping.

[0042] like Figures 4 to 6 As shown, guide grooves 211 are symmetrically provided inside the fixing sleeve 21 , and guide blocks 221 are symmetrically provided outside the vertical rod 22 . The guide blocks 221 are slidably connected to the guide grooves 211 .

[0043] In this embodiment, the cooperation between the guide groove 211 and the guide block 221 guides the vertical rod 22 , so that the vertical rod 22 is more stable when moving up and down.

[0044] like Figure 6 As shown, a connecting disk 242 is provided at one end of the screw rod 241, a rotating disk 243 is connected to the lower end of the connecting disk 242, and a handle 244 is provided at the lower end of the rotating disk 243;

[0045] The lower end of the rotating disk 243 is provided with connecting bolts 245 , and two groups of connecting bolts 245 are symmetrically provided. The rotating disk 243 and the connecting disk 242 are connected by the connecting bolts 245 .

[0046] In this embodiment, in the initial state, the connecting disk 242 and the rotating disk 243 are in a separated state. After the fixing sleeve 21 is inserted into the mounting hole 14 and fixed, the rotating disk 243 and the connecting disk 242 are connected by two sets of connecting bolts 245. The setting of the handle 244 and the rotating disk 243 allows the operator to rotate the screw rod 241 more conveniently, and the connection of the two sets of connecting bolts 245 makes the rotating disk 243 and the connecting disk 242 more stable to prevent falling off.

[0047] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
