[0034] At the same time, the side profiles of the door grooves corresponding to the small operating room door 2 and the bottom door 3 opened on the front of the JP cabinet 1 are all "convex" shaped, which are used to support the small operating room door 2 and the bottom door 3 to prevent the small operating room door 2 and the bottom door 3 from deviating toward the inside of the JP cabinet 1.

[0035] See also Figure 1 The interlocking assembly includes an interlock 5 and a door lock 6 which can simultaneously lock all the small operating room doors 2 and the bottom door 3.

[0036] Among them, the interlock 5 is vertically slidably installed at the center position of the front of the JP cabinet 1 through the installation sleeve 4, the door lock 6 is rotatably installed on the front of the JP cabinet 1 and located on both sides of the interlock 5, and the surface of the interlock 5 is slidably installed with a lock 7 fixedly connected to the JP cabinet 1.

[0037] See also Figure 3-4 The interlock 5 includes a first rod 51, a double-sided rack 52, a second rod 53 and a bottom bolt plate 54.

[0038] The upper and lower ends of the first rod 51 are welded with double-sided racks 52 , the second rod 53 is welded to the bottom end of the bottom double-sided rack 52 , and the bottom bolt plate 54 is welded to the bottom end of the second rod 53 .

[0039] Secondly, the second rod 53 is located inside the mounting sleeve 4 and is slidably connected to the mounting sleeve 4 .

[0040] Please refer to 3 or Figure 5 The door lock 6 includes a limit shaft rod 61 and a side door bolt plate 62 , and the side door bolt plate 62 is rotatably mounted on the surface of the limit shaft rod 61 .

[0041] There are four limiting shaft rods 61 symmetrically arranged, and each limiting shaft rod 61 is located on the transverse center line of the four small operating room doors 2 .

[0042] The side door bolt plate 62 is a plate body 621 with a flat surface on one side and an arc surface on the other side, and the arc surfaces of the two plate bodies 621 at the same height are opposite to each other. An axial hole 622 adapted to the limiting shaft rod 61 is opened on the plate body 621, and a plurality of meshing teeth 623 are integrally formed on the arc surface side of the plate body 621, and the meshing teeth 623 mesh with the double-sided rack 52.

[0043] When the double-sided rack 52 moves up and down, it will drive the four plates 621 to rotate synchronously at the same time.

[0044] See also Figure 3 or Figure 6 The locker 7 includes a lock box 71 fixed on the front of the JP cabinet 1 and a lock body 72 fixed on the surface of the No. 1 rod 51. A through hole vertically penetrating the lock box 71 is opened on the top of the lock box 71, and the No. 1 rod 51 vertically passes through the through hole and is slidably connected to the lock box 71.

[0045] Among them, the lock body 72 is located above the lock box 71, and a lock hole adapted to the lock body 72 is opened on the top of the lock box 71. The lock body 72 includes a movable plate 721 fixedly sleeved on the surface of the No. 1 rod 51, and a lock tongue 722 docked with the lock hole is fixedly installed at the bottom of the movable plate 721. Notch grooves 723 are opened on both sides of the movable plate 721.

[0046] Secondly, a No. 1 magnetic plate 55 is fixedly installed on the top of the No. 1 rod 51 , and a No. 2 magnetic plate 8 which attracts the No. 1 magnetic plate 55 is fixedly installed on the front of the JP cabinet 1 and above the No. 1 magnetic plate 55 .

[0047] It should be noted here that the specific working principle of the lock box 71 and lock body 72 structure used in the present application is similar to that of the door lock of the traditional JP cabinet, and both adopt the existing structure in the prior art, so they will not be described in detail in this article.

[0048] The working principle of the above embodiment is:

[0049] When locking, pinch the movable plate 721 and slide downward, and the movable plate 721 will move the interlock device 5 downward. As the interlock device 5 moves downward, the double-sided rack 52 in the interlock device 5 will simultaneously drive all the side door bolt plates 62 to rotate with their respective limiting shafts 61 as the center, so that the side door bolt plates 62 are rotated from a vertical state to a horizontal state, thereby moving the back side of the side door bolt plate 62 where the small operating room door 2 is located. When the lock tongue 722 is completely immersed in the lock box 71, the bottom door bolt plate 54 also moves to the front of the bottom door 3, thereby locking the bottom door 3. Finally, the lock core in the lock box 71 can be turned by the key to lock the lock tongue 722, thereby completing the door locking effect of all cabins.

[0050] When unlocking, the key is used to open the lock core in the lock box 71 to unlock the lock tongue 722. Under the mutual attraction between the No. 1 magnetic plate 55 and the No. 2 magnetic plate 8, the No. 1 magnetic plate 55 will automatically move up with the interlock 5, and then move all the side door bolt plates 62 to a vertical state again, thereby completing the unlocking operation of all cabin doors.

[0051] In the actual production process, a protective cover can be added to each door lock 6 on the front of the JP cabinet 1 to cover the meshing teeth 623 in the side door bolt plate 62, thereby reducing the entry of impurities into the meshing position of the meshing teeth 623 and the double-sided rack 52, thereby increasing the service life of the meshing teeth 623 and the double-sided rack 52. The shape of the large protective cover mentioned here is determined by the production personnel without affecting the normal operation of the meshing teeth 623 and the double-sided rack 52.

[0052] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
