[0002] An aircraft maintenance toolbox is a box for placing various aircraft maintenance tools, mainly used for aircraft airframe structure and accessory repair, assembly and debugging, aircraft flight test, its fault diagnosis and troubleshooting, etc. A plurality of drawers are installed inside the aircraft maintenance toolbox. In order to avoid the phenomenon that the gravity distribution of the device is unbalanced and the toolbox topples over when multiple drawers are opened simultaneously during the use of the aircraft maintenance toolbox, the aircraft maintenance toolbox needs to be provided with an anti-multi-opening function. Some anti-multi-opening drawer-type aircraft maintenance toolboxes include a box body, a control box, a drawer locking mechanism, a power supply module, and each layer of tool drawers; a display screen and an input keyboard are installed on the upper side of the control box, and a controller, an unlocking drive circuit, and a memory are arranged inside the control box; the drawer locking mechanism includes a mechanism housing, an unlocking motor, a vertical linkage rod, and each locking structure spaced in front of the vertical linkage rod; the locking structure is used for misaligned locking of the corresponding lock plate through a locking hole. This anti-multi-opening drawer-type aircraft maintenance toolbox uses the locking structure to misaligned lock the corresponding lock plate, so that only one tool drawer can be pulled out at a time, preventing the center of gravity of the toolbox from moving forward too much and toppling; the precise control of the vertical displacement of the vertical linkage rod is realized by using a screw driving seat, a driving screw, and an unlocking motor, so as to accurately locate which tool drawer is unlocked. However, when this device controls the anti-multi-opening of the aircraft maintenance toolbox, it is realized by the cooperation of multiple electrical components, which results in a relatively high production cost of the aircraft maintenance toolbox and needs to be improved.

Detailed Description of the Preferred Embodiment

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-3 , this embodiment provides a technical solution: an anti - multiple - opening drawer - type aircraft maintenance toolbox, including a maintenance box 1 and an anti - multiple - opening mechanism 4;

[0021] Maintenance box 1: Inside it, there are evenly distributed tool drawers 2 slidably connected. Chute threes are opened on the front and rear walls of the tool drawer 2, and evenly distributed moving partitions 5 are slidably connected between two longitudinally adjacent chute threes. Jacks 7 are evenly opened on the rear walls of the tool drawers 2. Locking bolts 6 are threadedly connected to the upper rear ends of the moving partitions 5, and the rear ends of the locking bolts 6 are inserted into the adjacent jacks 7. By sliding the moving partition 5 horizontally along the chute three and then rotating the locking bolt 6 so that its rear end is inserted into the adjacent jack 7, the space inside the tool drawer 2 of the drawer - type aircraft maintenance toolbox can be adjusted according to the usage requirements, which is convenient to use;

[0022] Anti-multi-opening mechanism 4: It includes a first chute 41, a sliding seat 42, a movable clamping seat 43 and an L-shaped clamping seat 44. The first chute 41 is opened at the right end of the front side of the maintenance box 1. The inside of the first chute is slidably connected with evenly distributed sliding seats 42. Second chutes are opened on the front sides of the sliding seats 42. The inside of the second chutes are slidably connected with movable clamping seats 43. Symmetrically distributed L-shaped clamping seats 44 are provided on the front sides of the tool drawers 2. The L-shaped clamping seats 44 are all installed in cooperation with the adjacent movable clamping seats 43. Pull handles 3 are provided in the middle of the front sides of the tool drawers 2. The anti-multi-opening mechanism 4 further includes a contact seat 45, a telescopic column 46 and a spring 47. The contact seats 45 are all slidably connected inside the first chute. The two contact seats 45 located between two vertically adjacent movable clamping seats 43 are fixedly connected through the telescopic column 46 and the spring 47. The springs 47 are all movably sleeved on the outer ends of the adjacent telescopic columns 46. The anti-multi-opening mechanism 4 further includes a dial button 48. The dial buttons 48 are all arranged on the front sides of the movable clamping seats 43. The anti-multi-opening mechanism 4 further includes a limit seat 49. The limit seats 49 are symmetrically arranged at the right end of the front side of the maintenance box 1. The limit seats 49 are all installed in cooperation with the adjacent movable clamping seats 43. In the initial state of the device, the adjacent movable clamping seats 43 are vertically limited by the limit seats 49 and by means of the compression elastic force of the spring 47, so that the left ends of the movable clamping seats 43 are all located in the middle of the adjacent two L-shaped clamping seats 44. And at this time, if the movable clamping seat 43 moves horizontally, there will be no movable clamping limit phenomenon between it and the adjacent L-shaped clamping seat 44. During the use of the drawer-type aircraft maintenance toolbox, when the staff pulls out a certain tool drawer 2, first, the staff horizontally moves the dial button 48 to the right to drive the corresponding movable clamping seat 43 to slide to the right along the second chute, so as to release the vertical movement limit of the tool drawer 2. Then, the tool drawer 2 can be pulled out through the pull handle 3. During the rightward movement of the movable clamping seat 43 corresponding to the tool drawer 2, the inclined surface of the movable clamping seat 43 is in pressing contact with the adjacent contact seat 45. Through the inclined surface guidance, the gap between the two contact seats 45 adjacent to the movable clamping seat 43 at this time is reduced, so that the telescopic ends of the telescopic columns 46 and the springs 47 adjacent to them are stretched, resulting in the balance destruction of the fact that the left ends of the movable clamping seats 43 are all located in the middle of the adjacent two L-shaped clamping seats 44 formed by the compression elastic force of the spring 47, so that the movable clamping seats 43 corresponding to the remaining tool drawers 2 all move vertically towards the tool drawer 2. Furthermore, the movable clamping seat 43 is clamped with the L-shaped clamping seat 44 in this moving direction, and the horizontal movement of the movable clamping seat 43 that locks the remaining tool drawers 2 is limited, so that the remaining movable clamping seats 43 cannot be pulled out from the front side of the tool drawer 2. Furthermore, when a certain tool drawer 2 of the device is pulled out, the device can automatically lock the remaining tool drawers 2 during the pull, so as to achieve the anti-multi-opening effect of the drawer-type aircraft maintenance toolbox, which is convenient to use. The device can automatically lock the remaining drawers when a certain drawer of the aircraft maintenance toolbox is opened through elastic elements and mechanical transmission. The device does not need to use electrical components and has a low production cost.

[0023] The working principle of a multi-opening prevention drawer-type aircraft maintenance toolbox provided by the present utility model is as follows: In the initial state of the device, the vertical movement of adjacent moving clamping seats 43 is limited by the limit seat 49, and by means of the compression elastic force of the spring 47, the left ends of the moving clamping seats 43 are located at the midpoints between two adjacent L-shaped clamping seats 44. At this time, if the moving clamping seats 43 move horizontally, there will be no moving clamping and limiting phenomenon with the adjacent L-shaped clamping seats 44. During the use of the drawer-type aircraft maintenance toolbox, when a staff member pulls out a certain tool drawer 2, first, the staff member horizontally moves the knob 48 to the right to drive the corresponding moving clamping seat 43 to slide to the right along the second chute, thereby releasing the vertical movement limit of the tool drawer 2. Subsequently, the tool drawer 2 can be pulled out by pulling the handle 3. During the rightward movement of the moving clamping seat 43 corresponding to the tool drawer 2, the inclined surface of the moving clamping seat 43 is in extrusion contact with the adjacent contact seat 45. Through the inclined surface guidance, the gap between the two adjacent contact seats 45 at this time is reduced, causing the telescopic ends of the telescopic columns 46 adjacent to it and the spring 47 to stretch. As a result, the balance in which the left ends of the moving clamping seats 43 are located at the midpoints between two adjacent L-shaped clamping seats 44 formed by the compression elastic force of the spring 47 is damaged, causing the moving clamping seats 43 corresponding to the remaining tool drawers 2 to move vertically towards this tool drawer 2. Furthermore, the moving clamping seats 43 are clamped with the L-shaped clamping seats 44 in this moving direction, and the horizontal movement of the moving clamping seats 43 that lock the remaining tool drawers 2 is limited, so that the remaining moving clamping seats 43 cannot be pulled out from the front side of the tool drawer 2. Therefore, when a certain tool drawer 2 of the device is pulled out, the device can automatically lock the remaining tool drawers 2 against pulling, thereby achieving the effect of preventing multi-opening of the drawer-type aircraft maintenance toolbox, which is convenient to use. Slide the movable partition 5 horizontally along the third chute, and then rotate the locking bolt 6 so that its rear end is inserted into the adjacent jack 7, so that the space in the tool drawer 2 of the drawer-type aircraft maintenance toolbox can be adjusted according to the use requirements, which is convenient to use.

[0024] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present utility model.
