DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in the field of surgical instrument trays without creative work are within the scope of protection of the utility model.

[0026] like Figure 1 , 2 As shown in Figure 3, the utility model provides an adjustable surgical instrument tray, a connecting frame 1: a rotating motor 12 is fixedly arranged at the lower inner end of the connecting frame 1, a limiting base 10 is fixedly arranged at the inner side of the connecting frame 1, a threaded shaft 13 is fixedly arranged at the output end of the rotating motor 12, two limiting plates 11 are fixedly arranged on the outer surface of the threaded shaft 13, the two limiting plates 11 are respectively located at the upper and lower ends of the limiting base 10, and four slide grooves 14 are opened at the upper end of the connecting frame 1; an adjusting adapter 6 is movably arranged on the outer surface of the threaded transmission device 2, a first support arm 7 is movably arranged on one side of the adjusting adapter 6, a second support arm 8 is movably arranged on one side of the first support arm 7, and a tray 9 is movably arranged at one end of the second support arm 8;

[0027] In order to achieve lifting and lowering by rotating the thread, a thread transmission device 2 that can achieve lifting and lowering by rotating the thread is provided on the inner side of the connecting frame 1. The thread transmission device is located outside the thread shaft and is used to adjust the height of the tray 9.

[0028] like Figure 3As shown, the threaded transmission device 2 includes a sliding block 21, which is movably arranged on the inner side of the connecting frame 1. The four sides of the sliding block 21 protrude outward and are movably connected to the four sliding grooves 14. A threaded groove 22 is provided on the inner side of the sliding block 21, and the threaded groove 22 is threadedly connected to the threaded shaft 13. The movement limit of the sliding block 21 can be achieved through the sliding block 21 and the sliding groove 14. The forward and reverse rotation of the rotating motor 12 is controlled by the lifting controller 5 through the threaded connection between the threaded shaft 13 and the threaded groove 22. When the rotating motor 12 drives the threaded shaft 13 to rotate, the sliding block 21 can be moved up and down. The setting of the sliding groove 14 prevents the sliding block 21 from rotating, thereby solving the problem of the trouble of medical staff in adjusting the height in the prior art.

[0029] Furthermore, in order to be able to adjust the position of the tray 9 by pulling, a pulling adjustment device 3 for adjusting the position by pulling is respectively provided between the adjusting adapter 6, the first support arm 7, the second support arm 8 and the tray 9, which is used to pull the second support arm 8 and the first support arm 7 to adjust the distance between the tray 9 and the connecting frame 1 to reduce the volume.

[0030] like Figure 4 As shown, the pulling and adjusting device 3 includes three slots 31, which are respectively arranged at the upper end of the first support arm 7, the lower end of the second support arm 8 and one side of the adjusting adapter 6. A limiting slot 33 is arranged on the inner wall of the slot 31, and first anti-slip pads 34 are fixedly arranged on both sides of the inner wall of the slot 31, and a rotating block 32 is fixedly arranged on the upper end of the second support arm 8, the upper end of the tray 9 and the lower end of the first support arm 7 respectively. Second anti-slip pads 35 are fixedly arranged on both sides of the rotating block 32, and a limiting shaft 36 passes through the inner side of the rotating block 32. Both ends of the limiting shaft 36 respectively pass through the limiting slot 33 and are movably connected between the limiting slots 33. By pulling the tray 9, the first support arm 7 and the second support arm 8 are driven to be straightened, thereby realizing the position adjustment of the tray 9. Because the two support arms are movably connected, when the tray 9 is recovered, the bending position can be moved upward to reduce the placement space of the support arms and prevent collision with medical staff.

[0031] The working principle is as follows: In the utility model, the connecting frame 1 is fixed by the chassis 4, and the position limit of the connecting frame 1 is achieved by the weight of the chassis 4. The lifting controller 5 controls the rotating motor 12, so that the sliding block 21 of the threaded transmission device 2 can be lifted up and down due to the rotation of the threaded shaft 13. An adjustment adapter 6 is provided on the outer surface of the sliding block to achieve lateral angle adjustment of the tray 9. The pulling adjustment device 3 is used to connect the first support arm 7, the second support arm 8 and the tray 9. Since the first support arm 7 and the second support arm 8 can be bent, the placement space is reduced and the risk of collision with medical staff is reduced.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
