[0045] The present invention will be further described below with reference to the embodiments.

[0046] pass Figures 1-10 As can be seen, the screw sterilization box with a fixed opening and closing angle structure includes a cover plate 1 and a box body 2. The cover plate 1 is located at the upper section of the screw sterilization box, and the box body 2 is located at the lower section of the screw sterilization box. The rear end of the cover plate 1 and the rear end of the box body 2 are rotatably connected, which enables the rotation and opening of the cover plate 1.

[0047] The cover plate 1 is provided with a cover plate locking pull plate 103, and the box body 2 is provided with a box body locking fixing plate 209. The cover plate locking pull plate 103 and the box body locking fixing plate 209 can be locked together to prevent the disinfection box from being accidentally opened during turnover, which would cause the screws to fall off.

[0048] Rotary positioning posts 102 are provided on both sides of the rear end of the cover plate 1. A cover plate limiting groove 207 is provided at the rear end of the upper end of the box body 2. The two sides of the cover plate limiting groove 207 are located on the left and right sides of the box body 2, respectively. The cover plate limiting groove 207 is a longitudinally recessed long groove. A cover plate rotating support seat 203 is provided on the left and right sides of the rear end of the box body 2, respectively. The two sides of the cover plate limiting groove 207 are located inside the two cover plate rotating support seats 203.

[0049] The two cover plate rotating support seats 203 are respectively provided with cover plate rotating support holes 204 at the upper end of the cover plate limiting groove 207. The cover plate rotating support holes 204 are connected to the cover plate limiting groove 207 vertically.

[0050] Regarding the specific structure of the cover plate rotation support hole 204, in this patent, the cover plate rotation support hole 204 is a circular hole, which can increase the smoothness of the rotation of the rotation positioning column 102 when it rotates inside.

[0051] When the cover plate 1 is in the closed state, the two rotating positioning pins 102 are located inside the two cover plate rotating support holes 204 respectively. The two rotating positioning pins 102 are rotatably connected to the two cover plate rotating support holes 204. When the cover plate 1 is opened to a position parallel to the cover plate limiting groove 207, under the action of gravity, the rear end of the cover plate 1 will fall into the cover plate limiting groove 207, thereby achieving the limiting effect on the cover plate 1.

[0052] The diameter of the cover plate rotation support hole 204 is greater than the width of the cover plate limiting groove 207, the thickness of the rotation positioning post 102 is less than the width of the cover plate limiting groove 207, and the front and rear width of the rotation positioning post 102 is greater than the width of the cover plate limiting groove 207. With the above dimensions, the cover plate 1 can be opened smoothly and the rotation positioning post 102 can fall smoothly into the interior of the cover plate limiting groove 207.

[0053] For the disinfection of screws, in this patent, the cover plate 1 is provided with a longitudinally penetrating disinfection hole 101, the box body 2 is provided with a receiving cavity 212, the bottom of the receiving cavity 212 is provided with a receiving cavity bottom plate 21201, and the receiving cavity bottom plate 21201 is provided with a longitudinally penetrating disinfection hole 201.

[0054] The cover plate 1 has multiple disinfection holes 101, which are evenly distributed on the cover plate 1. The bottom plate 21201 of the receiving cavity also has multiple disinfection holes 201, which are evenly distributed on the bottom plate 21201 of the receiving cavity. This ensures that the disinfection steam can quickly enter every corner of the disinfection box during the screw disinfection process, thereby increasing the coverage area and disinfection efficiency of the steam entering the disinfection box during steam disinfection.

[0055] A screw fixing plate support 208 is provided on the outer side of the receiving cavity 212. A screw fixing plate 4 is provided at the upper end of the screw fixing plate support 208. The screw fixing plate 4 is provided with multiple screw placement holes 402.

Furthermore, a part of the screw fixing plate support 208 is located on the outer side of the screw placement cavity 206. The screw placement hole 402 is used to place small screws, and the screw placement cavity 206 is used to place large screws. Since large screws are less likely to fall out during handling, there is no need to set a separate screw placement hole 402 inside the screw placement cavity 206. This ensures convenient access to large screws during surgery and reduces the manufacturing cost of the sterilization box.

[0057] Regarding the specific structure of the screw placement hole 402, in this patent, multiple screw placement holes 402 are arranged into multiple groups on the screw fixing plate 4. The diameter of the screw placement holes 402 in each group is different. Screws with different outer diameters can be inserted through different diameter holes, which has a wide range of applications. Through a screw sterilization box, the placement, sterilization and use of screws of various specifications can be realized, which increases the convenience of use in surgery.

[0058] Regarding the specific structure of the screw fixing plate 4, in this patent, the screw fixing plate 4 is provided with multiple classification lines 401. The multiple classification lines 401 distinguish the screw placement holes 402 between each group. With the combined effect of setting screw placement holes 402 of different diameters and multiple classification lines 401, the doctor can quickly and accurately find the required screw during the operation, which is safe and shortens the time for picking up the screw, thereby ensuring the smooth progress of the operation.

[0059] Regarding the specific structure of the box 2, in order to facilitate the verification of the specific size of the screws, in this patent, a screw measuring slot 205 is provided at the leftmost position of the box 2.

A second screw placement slot 210 is provided on the screw fixing plate 4 at the right side of the first screw placement slot 20502. The second screw placement slot 210 is connected to the first screw placement slot 20502. The side of the second screw placement slot 210 is provided with a scale line 211.

[0060] When a secondary verification of the screw length is required, the screw length verification operation can be completed through the screw measuring slot 205.

[0061] The specific operation method is as follows: First, the inner end of the screw nut is placed in the nut positioning groove 20501, and the screw shaft is then placed into the first screw placement groove 20502 and the second screw placement groove 210. The screw length is verified by the scale line 211. The whole verification process is simple, quick and easy and the effect is intuitive.

[0062] Regarding the specific locking method between the cover plate 1 and the box body 2, in this patent, the cover plate locking lifting plate 103 is provided with a first through hole 10301, and the box body locking fixing plate 209 is provided with a second through hole 20901.

A first limiting post 303 is provided on the outer circumference of the connecting rod 304 between the spring 302 and the second limiting post 305. The first limiting post 303 and the spring 302 are slidably connected to the connecting rod 304. The first limiting post 303 is located on the upper outer side of the first through hole 10301. The connecting rod 304 is located inside the first through hole 10301. The second limiting post 305 is located on the lower outer side of the first through hole 10301. A through hole is provided on the right side of the second through hole 20901. The inner diameter of the through hole is larger than the outer diameter of the second limiting post 305. A locking support groove 20902 is provided on the lower left side of the second through hole 20901. The outer diameter of the locking support groove 20902 is larger than the outer diameter of the second limiting post 305.

[0063] In actual use, when it is necessary to lock the cover plate 1, firstly, rotate the cover plate 1 to fit the lower end of the cover plate 1 against the box body 2, press the locking pull post 301 to fit the first limiting post 303 against the cover plate 1, continue to press the locking pull post 301, the connecting rod 304 and the second limiting post 305 move downwards simultaneously, the connecting rod 304 and the second limiting post 305 pass through the through hole on the right side of the second through hole 20901, at this time, the second limiting post 305 is located below the second through hole 20901, and the spring 302 is under compression. Then, while pressing the locking pull post 301, move the locking pull post 301 to the left. The connecting rod 304 and the second limiting post 305 move to the left at the locking support groove 20902 on the lower left side of the second through hole 20901. Finally, release the locking pull post 301. The upper end of the second limiting post 305 is engaged with the lower end of the locking support groove 20902. At this time, the spring 302 is partially unfolded and is still in a compressed state, thereby achieving the closed locking between the cover plate 1 and the box body 2.

[0064] When it is necessary to open the cover plate 1, firstly, press the locking pull post 301. The connecting rod 304 and the second limiting post 305 move downwards simultaneously.
