[0040] Please refer to Figure 1 to Figure 2The present invention provides a keyboard drawer structure 100 with a pull-out linkage to eject a mouse tray, comprising a desktop bottom shell 1 and a keyboard tray 2 slidably connected to the desktop bottom shell 1, wherein the keyboard tray 2 can be pulled out or pushed into the desktop bottom shell 1. In the embodiment of the present invention, a slide rail 7 is connected between the desktop bottom shell 1 and the keyboard tray 2, and the slide rail 7 includes two parts, one part is mounted on the desktop bottom shell 1, and the other part is mounted on the keyboard tray 2. The two parts can slide relative to each other so that the keyboard tray 2 and the desktop bottom shell 1 can slide relative to each other. The keyboard tray 2 is used to place a keyboard 200, such as Figure 2 As shown, a keyboard slot 25 is provided on the keyboard tray 2 for accommodating the keyboard 200 , so that the keyboard 200 can slide on the keyboard tray 2 .

[0041] Preferably, the front side wall of the desktop bottom shell 1 of the present invention is provided with a drawer opening 12, and the keyboard tray 2 is pulled out or pushed in from the drawer opening 12. The drawer opening 12 can support the keyboard tray 2 and limit the shaking of the keyboard tray 2 in the left and right directions.

[0042] The keyboard tray 2 of the present invention is also rotatably connected to a mouse tray 3 that can be screwed into or out of the keyboard tray 2. The mouse tray 3 is used to place a mouse. The keyboard tray 2 of the present invention can have a receiving groove dedicated to accommodating the mouse tray 3, or the mouse tray 3 can be rotated and hidden at the bottom of the keyboard tray 2. When not in use, the mouse tray 3 is screwed into the keyboard tray 2 to save space and reduce the space occupied by the medical cart. When in use, the mouse tray 3 is screwed out of the keyboard tray 2 and the mouse can be placed on it for use.

[0043] Specifically, Figure 3 and Figure 4 As shown, a connection hole 21 is provided on one side of the keyboard tray 2 of the embodiment of the present invention, and a bearing 22 is installed in the connection hole 21. A rotating shaft 33 is provided on the mouse tray 3, and the rotating shaft 33 is installed in the bearing 22 and can rotate. In this way, through the action of the rotating shaft 33 and the bearing 22, the connection between the mouse tray 3 and the keyboard tray 2 is achieved on the one hand, and the rotation between the mouse tray 3 and the keyboard tray 2 is achieved on the other hand to achieve the effect of screwing in or out. The rotation connection between the rotating shaft 33 and the bearing 22 makes the rotation between the mouse tray 3 and the keyboard tray 2 smooth and stable.

[0044] Preferably, the keyboard tray 2 of the embodiment of the present invention is provided with a tray slot 23 at the bottom of the connection hole 21 area, and the mouse tray 3 is hidden in the tray slot 23 when it is screwed into the keyboard tray 2. The tray slot 23 is specially used to accommodate the mouse tray 3, achieving a hiding effect.

[0045] Preferably, when the mouse tray 3 is hidden in the tray slot 23, the bottom surface of the mouse tray 3 is higher than the bottom surface of the keyboard tray 2 or is flush with the bottom surface of the keyboard tray 2. That is, when the mouse tray 3 is stored in the tray slot 23, its bottom will not protrude from the bottom of the keyboard tray 2, so that the entire keyboard tray 2 can be pulled out or pushed into the desktop bottom shell 1.

[0046] Furthermore, the keyboard tray 2 of the embodiment of the present invention is provided with a limiting groove 24 on the side having the connecting hole 21, and the mouse tray 3 is provided with a limiting block 34. After the limiting block 34 is screwed into the limiting groove 24, the mouse tray 3 stops the original rotation direction.

[0047] The connection hole 21 of this embodiment is arranged at the edge of the keyboard tray 2, and the limiting groove 24 is arranged on the side of the connection hole 21, and two limiting grooves 24 are symmetrically arranged on both sides of the connection hole 21. The limiting groove 24 can prevent the mouse tray 3 from excessively rotating during the process of being screwed in and out.

[0048] A spring-loaded buckle 4 is connected between the front end of the keyboard tray 2 in the push-in direction and the desktop bottom shell 1 in the embodiment of the present invention, and the spring-loaded buckle 4 locks and fixes the keyboard tray 2 and the desktop bottom shell 1 or unlocks and loosens them.

[0049] Specifically, Figure 5 and Figure 6 As shown, the spring-loaded buckle 4 of the present invention includes a lock seat 41 arranged on the desktop bottom shell 1, and a lock buckle 42 arranged at the front end of the keyboard tray 2 in the pushing direction. The lock buckle 42 is locked and fixed with the lock seat 41 or unlocked and loosened.

[0050] The lock base 41 is integrated with a spring structure and a locking structure. When the lock buckle 42 and the lock base 41 are in the unlocked and loose state, if the lock buckle 42 is pushed by an external force and abuts against the lock base 41, the lock base 41 will buckle the lock buckle 42 to achieve locking and fixing; when the lock buckle 42 and the lock base 41 are in the locked and fixed state, if the lock buckle 42 is pushed by an external force again, the lock base 41 will unlock and loosen the lock buckle 42. In this way, when the keyboard tray 2 is to be used, the keyboard tray 2 is pressed inward, the lock base 41 unlocks and loosens the lock buckle 42, and the keyboard tray 2 is loosened from the desktop bottom shell 1, and then the keyboard tray 2 can be pulled out. When the keyboard tray 2 is used and wants to be stored, the keyboard tray 2 is pushed inward until the lock buckle 42 abuts against the lock base 41 and is locked and fixed. At this time, the keyboard tray 2 is locked and fixed to the desktop bottom shell 1 and cannot be directly pulled out.

[0051] like Figures 7 to 11As shown, the desktop bottom shell 1 of the keyboard drawer structure 100 of the present invention is further provided with a fixing spring 5 and an ejection spring 6, and the fixing spring 5 and the ejection spring 6 are located below the bottom surface of the keyboard tray 2. When the keyboard tray 2 is pulled out from the desktop bottom shell 1, the mouse tray 3 is disengaged from the fixing spring 5 and is pressed by the ejection spring 6 to rotate relative to the keyboard tray 2, as shown in FIG. Figure 8 When the keyboard tray 2 is pushed into the desktop bottom shell 1, the mouse tray 3 abuts against the fixing spring 5 and the ejection spring 6, and the mouse tray 3 is fixed by the fixing spring 5. Figure 7 as shown in .

[0052] The fixing spring 5 fixes the mouse tray 3 when the mouse tray 3 is stored in the keyboard tray 2. The ejection spring 6 automatically rotates the mouse tray 3 out of the keyboard tray 2 by elastic force when the keyboard tray 2 is pulled out of the desktop bottom case 1, thereby exposing the mouse tray 3 hidden in the keyboard tray 2.

[0053] The arrangement of the fixing spring 5 and the ejection spring 6 enables the keyboard tray 2 and the mouse tray 3 to have a linkage effect, that is, when the keyboard tray 2 is pulled out from the desktop bottom shell 1, the mouse tray 3 automatically rotates out following the outward movement of the keyboard tray 2. Figure 8 Fig. 9 As shown, the mouse tray 3 will not be automatically rotated out until the ejection spring 6 is out of contact with the mouse tray 3.

[0054] Specifically, Figure 7 As shown, the mouse tray 3 of the embodiment of the present invention comprises a top wall 31 and a side wall 32 arranged adjacent to each other. When the keyboard tray 2 is pushed into the desktop bottom shell 1, the fixing spring 5 abuts against the side wall 32, and the ejection spring 6 abuts against the top wall 31. The fixing spring 5 abuts against the side wall 32 of the mouse tray 3 to fix the mouse tray 3, and the ejection spring 6 abuts against the top wall 31 of the mouse tray 3 to accumulate elastic force for the mouse tray 3 to be pressed and rotated out.

[0055] The fixing spring 5 and the ejection spring 6 of the present invention can adopt various types of springs that can achieve the above functions, such as a spiral spring, a plate spring, a leaf spring, etc.

[0056] The linkage process of the keyboard tray 2 and the mouse tray 3 of the present invention is as follows:

[0057] 1. When the keyboard tray 2 and the mouse tray 3 are to be used, the keyboard tray 2 is pressed into the desktop bottom shell 1 by hand, and the spring-pressed buckle 4 will push out the keyboard tray 2 after being pressed, and the keyboard tray 2 is pulled outward, and the side wall 32 of the mouse tray 3 will gradually break away from the fixing spring 5. After the side wall 32 of the mouse tray 3 is completely out of contact with the fixing spring 5, the fixing spring 5 can no longer fix the mouse tray 3. At this time, under the elastic force of the ejection spring 6 acting on the top wall 31 of the mouse tray 3, the mouse tray 3 starts to rotate around the rotation axis 33 and automatically rotates out relative to the keyboard tray 2, as shown in FIG. Fig. 9 As shown, until the ejection spring 6 is out of contact with the top wall 31 of the mouse tray 3 and no longer automatically rotates out, at this time, if the mouse tray 3 is not completely rotated out, you can use your hands to help rotate the mouse tray 3 to the position shown in FIG. Fig.10 The fully rotated out position is shown in .

[0058] 2. When you want to store the keyboard tray 2 and the mouse tray 3 after use, push the keyboard tray 2 inwards. At this time, the mouse tray 3 will automatically rotate into the keyboard tray 2 under the action of the side of the desktop bottom shell 1 following the movement of the keyboard tray 2. The keyboard tray 2 continues to be pushed in, and the mouse tray 3 is further rotated in by hand, so that the mouse tray 3 gradually abuts against the fixing spring 5 and the ejection spring 6, until the spring-pressing buckle 4 is pressed again to clamp the keyboard tray 2. At this time, the fixing spring 5 will also support the side wall 31 of the fixed mouse tray 3, and the mouse tray 3 will not rotate out.

[0059] As an implementation method, Fig.11 As shown, the fixing spring 5 of the present invention is in the form of a sheet, one end of the fixing spring 5 is fixed on the desktop bottom shell 1, a sliding groove 11 is provided in the desktop bottom shell 1, the other end of the fixing spring 5 is accommodated in the sliding groove 11, and a protrusion 51 is provided in the middle of the fixing spring 5 for contacting with the side wall 32 of the mouse tray 3. The protrusion 51 contacts or breaks contact with the side wall 32 of the mouse tray 3, so that the distance between the two ends of the fixing spring 5 becomes longer or shorter, and the sliding groove 11 can match the change of the distance between the two ends of the fixing spring 5, and at the same time can prevent the non-fixed end of the fixing spring 5 from rotating left and right, so that the non-fixed end of the fixing spring 5 can only move up and down in the sliding groove 11.

[0060] As an implementation method, Figure 7 and Fig. 9 As shown, the ejection spring 6 of the present invention is in the form of a sheet, one end of the ejection spring 6 is fixed to the desktop bottom shell 1, and the other end of the ejection spring 6 is used to abut against the top wall 31 of the mouse tray 3. The non-fixed end of the ejection spring 6 abuts against the top wall 31 of the mouse tray 3, and can rotate around the fixed end to press the mouse tray 3 and force the mouse tray 3 to rotate and unscrew.

[0061] The present invention further provides a medical cart (not shown), comprising the above-mentioned keyboard drawer structure 100 for pulling out and popping out the mouse tray. Due to the keyboard drawer structure for pulling out and popping out the mouse tray, the mouse tray 3 of the medical cart of this embodiment can be stored to save space, and can be popped out in linkage with the keyboard tray 2.

[0062] The keyboard drawer structure 100 and the medical cart for pulling out and ejecting the mouse tray proposed in the embodiment of the present invention are configured such that the mouse tray 3 and the keyboard tray 2 are connected in a rotational manner so as to be screwed in or out. At the same time, a fixing spring 5 and an ejection spring 6 are also provided in the desktop bottom shell 1 to act on the mouse tray 3, so that when the keyboard tray 2 is pulled out from the desktop bottom shell 1, the mouse tray 3 is pressed by the ejection spring 6 and is screwed out relative to the keyboard tray 2; and when the keyboard tray 2 is pushed into the desktop bottom shell 1, the mouse tray 3 is fixed by the fixing spring 5. In this way, the mouse tray 3 can be stored and hidden in the keyboard tray 2 to save space, and when the keyboard tray 2 is pulled out, the mouse tray 3 is automatically screwed out from the keyboard tray 2, and there is no need to manually release the limit fixation of the mouse tray by the fixing spring 5, which saves manpower and facilitates operation.

[0063] The above description is only an example to clearly illustrate the present invention, and does not limit the patent scope of the present invention. It is impossible to list all the implementation methods here. All equivalent structural changes made by using the contents of the technical solution of the present invention under the concept of the present invention, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present invention.
