DETAILED DESCRIPTION

[0027] The utility model will be further explained below in combination with the drawings and embodiment.

[0028] First embodiment

[0029] Please combine with reference to Figure 1 , Figure 2 , Figure 3 , Figure 4 And Figure 5 Among them, Figure 1 A structure schematic view of a first embodiment of the mutual restriction type multi-drawer locking structure for a tool box provided by the utility model; Figure 2 For Figure 1 The structure schematic view of drawer shown; Figure 3 For Figure 1 The structure schematic view of the section of box body shown; Figure 4 For Figure 2 The A part enlarged schematic view shown; Figure 5 For Figure 3 The B part enlarged schematic view shown. A mutual restriction type multi-drawer locking structure for a tool box, comprising:

[0030] Box body 1;

[0031] Multiple drawers 2, multiple the drawer 2 all are arranged in the inside of box body 1, multiple the inside of drawer 2 all is set with two moving grooves 21, multiple the inside of moving groove 21 all is fixedly connected with pressing block 22, multiple the inside of moving groove 21 all is fixedly connected with positioning block 23;

[0032] A plurality of reset grooves 3 are arranged in the interior of the box 1, a reset block 31 is slidably connected in each of the plurality of reset grooves 3, a reset spring 32 is arranged at the bottom of each of the plurality of reset blocks 31 and located in the interior of each of the plurality of reset grooves 3, a plurality of connecting rods 33 are fixedly connected to the surface of each of the plurality of reset blocks 31, and a limiting block 34 is fixedly connected to one side of each of the plurality of reset blocks 31.

[0033] One end of the pressing block 22 is a slope, which is used to move downward along the slope of the pressing block 22 after the limiting block 34 contacts the pressing block 22.

[0034] The positioning block 23 is used to limit the drawer 2 after the limiting block 34 moves downward to one side of the positioning block 23, so that when one drawer 2 moves to one side for removal, the drawers 2 on other layers cannot move to one side.

[0035] The plurality of reset grooves 3 are arranged in the interior of the box 1, three of the plurality of reset blocks 31 are arranged in a group, and the three reset blocks 31 are connected by two connecting rods 33, so that when one reset block 31 moves downward, the other reset blocks 31 can be driven to move downward.

[0036] The limiting block 34 cooperates with the positioning block 23 to limit the drawer 2, so that when one drawer 2 moves to one side for removal, the drawers 2 on other layers cannot move to one side, and at the same time, the removed drawer 2 can be limited to prevent the drawer 2 from separating from the box 1.

[0037] The interior of each of the plurality of limiting blocks 34 is rotatably connected with a rotating rod 4, and the surface of each of the plurality of rotating rods 4 is fixedly connected with a rotating roller 5.

[0038] The rotating roller 5 is used to reduce the friction between the limiting block 34 and the pressing block 22 when the limiting block 34 moves to one side after contacting the slope of the pressing block 22.

[0039] Four moving wheels 6 are fixedly installed at the bottom of the box 1 and located at the four corners of the bottom of the box 1.

[0040] The moving wheels 6 are universal wheels, which are used to facilitate the movement of the box 1 to one side.

[0041] A handle 7 is fixedly connected to one side of the box 1, and a protective frame 8 is fixedly connected to the top of the box 1.

[0042] The handle 7 is used to move the box 1 to one side, and the protective frame 8 is used to protect the tools placed on the top of the box 1 from falling off when the box 1 is pushed to move.

[0043] The working principle of the mutual restriction type multi-drawer locking structure for a tool box is as follows:

[0044] When used, the drawer 2 of one layer is pulled to one side to drive the moving groove 21 to move on the surface of the limiting block 34 to one side, and when the surface of the limiting block 34 contacts the inclined surface of the pressing block 22, the limiting block 34 moves downward along the inclined surface, thereby driving the reset block 31 to move downward in the reset groove 3 while the reset spring 32 is extruded, and when the reset block 31 moves downward, the connecting rod 33 connects the other reset blocks 31 to move downward, so that the plurality of limiting blocks 34 move downward to contact the positioning blocks 23 to limit the drawers 2 of other layers.

[0045] When the drawer 2 is pushed back to reset, the reset spring 32 pushes the reset block 31 to reset the limiting block 34, thereby driving the connecting rod 33 to reset the other reset blocks 31, so that the other limiting blocks 34 are separated from the other positioning blocks 23, and at this time, the drawers 2 of other layers can be pulled out.

[0046] Compared with the related art, the mutual restriction type multi-drawer locking structure for a tool box has the following beneficial effects:

[0047] The mutual restriction type multi-drawer locking structure for a tool box is provided, the pressing block 22 cooperates with the positioning block 23, the reset groove 3, the reset block 31, the reset spring 32, the connecting rod 33 and the limiting block 34, so that when the drawer 2 of one layer is pulled out, the positioning blocks 23 of other layers are blocked by the limiting block 34, and after the drawer 2 is reset, the positioning blocks 23 are automatically separated from the limiting block 34, thereby enabling the multi-layer drawers 2 to be opened only simultaneously, and facilitating the staff to quickly pull out and push back the drawers, and facilitating the staff to use the tool box.

[0048] Second embodiment
