[0027] Figure 6 This is a schematic diagram of the structure of the stop block in this utility model.

[0028] A tool cart with drawer anti-multiple-opening effect includes: a base plate 1, with wheels 2 below the base plate 1, a handle 3 and a drawer cabinet 4 above the base plate 1, multiple sets of equidistantly distributed mounting grooves 5 and anti-multiple-opening limiting components fixedly connected to both sides of the inner wall of the drawer cabinet 4, drawers 6 slidably connected to the mounting grooves 5, lifting grooves 7 provided on both sides of the inner wall of the drawer cabinet 4, lifting blocks 8 slidably connected in the lifting grooves 7, the number of lifting blocks 8 being equal to the number of drawers 6, a connecting rod 9 fixedly connected between two adjacent sets of lifting blocks 8 in the middle, the anti-multiple-opening limiting component including a limiting member 10, a wing plate 11 and a linkage member 12, the wing plate 11 being rotatably connected to the limiting member 10, the linkage member 12 being rotatably connected to the limiting member 10, and stops 13 fixedly connected to both sides of the drawer cabinet 4, the positions of the stops 13 corresponding to the wing plates 11.

[0029] When stationary, the wing plate 11 is located between the stop block 13 and the inner wall of the drawer cabinet 4. During the process of pulling out the drawer 6, the wing plate 11 rotates and disengages from the stop block 13. Through the limiting member 10 and the linkage member 12, the adjacent wing plate 11 and the drawer 6 are locked. At the same time, due to the action of the connecting rod 9, the lower lifting block 8 moves downward, and the lower anti-multiple opening limiting component restricts the lower drawer 6 from being pulled out.

[0030] The drawer 6 includes a main body 61 and a slot 64. The main body 61 has sliding parts 62 on both sides, which are slidably connected to the mounting groove 5. A first partition plate 63 is fixedly connected to the middle of the main body 61. The slots 64 are equidistantly distributed on both sides of the inner wall of the main body 61 and on both sides of the first partition plate 63. A second partition plate 65 is inserted into the slot 64.

[0031] The slot 64 can be inserted into multiple second partitions 65 at different positions, dividing the internal space of the main body 61 into sections of different sizes to accommodate the placement needs of different items inside.

[0032] The limiting component 10 includes a fixed base 101, which is fixedly connected to the inner wall of the drawer cabinet 4. A sliding strip 102 is fixedly connected to the inner side of the fixed base 101. A first T-shaped block 103 and a second T-shaped block 105 are slidably connected on the sliding strip 102. Positioning plates 104 are fixedly connected to the upper and lower sides of the first T-shaped block 103. The first T-shaped block 103 and the second T-shaped block 105 are fixedly connected.

[0033] The first T-block 103 and the second T-block 105 slide along the sliding bar 102, which serves to link and control the locking function.

[0034] The airfoil 11 is located between the first T-block 103 and the second T-block 105. The airfoil 11 includes an airfoil body 111. A rotating seat 112 is fixedly connected to the airfoil body 111. The rotating seat 112 is rotatably connected to the fixed seat 101. A first push plate 113 and a second push plate 114 are provided on both sides of the rotating seat 112. The first push plate 113 is close to the first T-block 103, and the second push plate 114 is close to the second T-block 105.

[0035] When drawer 6 is pulled out, the wing-shaped plate body 111 disengages from the stop block 13 and is driven to rotate, causing the first push plate 113 to rotate around the rotating seat 112 and touch the first T-shaped block 103, causing it to slide along the sliding strip 102 and drive the linkage 12 to rotate; when drawer 6 is closed, the wing-shaped plate body 111 is pushed by the stop block 13 and re-enters its inner side, the second push plate 114 touches the second T-shaped block 105, and the first T-shaped block 103, the second T-shaped block 105 and the wing-shaped plate body 111 return to the original position before the drawer 6 was pulled out.

[0036] The linkage 12 is located between the first T-block 103 and the positioning plate 104. The linkage 12 includes a linkage body 121. A first rotating shaft 122 and a second rotating shaft 125 are provided on the linkage body 121. The first rotating shaft 122 is rotatably connected to the fixed base 101, and the second rotating shaft 125 is rotatably connected to the lifting block 8. A third push plate 123 and a fourth push plate 124 are provided on both sides of the first rotating shaft 122. The third push plate 123 is close to the first T-block 103, and the fourth push plate 124 is close to the positioning plate 104.

[0037] When the wing-shaped plate body 111 touches the first T-shaped block 103, it slides along the sliding bar 102. The first T-shaped block 103 touches the third push plate 123, causing the linkage body 121 to rotate, so that the lifting block 8 slides along the lifting groove 7, thereby locking the anti-multiple opening limit components in other positions, preventing the corresponding drawer 6 from being opened. When the drawer 6 is closed, the positioning plate 104 touches the fourth push plate 124, causing the linkage body 121 to rotate, so that the lifting block 8 slides along the lifting groove 7, thus releasing the lock.

[0038] The stop block 13 includes a stop block body 131. A triangular end 132 is provided on the side of the stop block body 131 facing the inside of the drawer cabinet 4. A limiting groove 133 is provided between the stop block body 131 and the triangular end 132. Rounded corners 134 are provided on both sides of the limiting groove 133.

[0039] When the airfoil body 111 is located inside the stop block 13, that is, within the limiting groove 133, the arc angle 134 makes the airfoil body 111 enter the limiting groove 133 more smoothly and reduces wear.

[0040] The working principle of the tool cart with drawer anti-multiple-opening effect provided by this utility model is as follows:

[0041] When stationary, the wing plate 11 is located between the stop block 13 and the inner wall of the drawer cabinet 4. During the process of pulling out the drawer 6, the wing plate 11 rotates and disengages from the stop block 13. Through the limiting member 10 and the linkage member 12, the adjacent wing plate 11 and the drawer 6 are locked. At the same time, due to the action of the connecting rod 9, the lower lifting block 8 moves downward, and the lower anti-multiple opening limiting component restricts the lower drawer 6 from being pulled out.

[0042] Compared with related technologies, the tool cart with drawer anti-multiple-opening function provided by this utility model has the following beneficial effects:

[0043] With the cooperation of the anti-multiple opening limit assembly consisting of limit member 10, wing plate 11 and linkage member 12, and the lifting groove 7, lifting block 8, connecting rod 9 and the stop blocks 13 on both sides of drawer 6, when any drawer is pulled open, the other drawers 6 will be locked by the anti-multiple opening limit assembly at the corresponding position and cannot be pulled open, thus preventing the dangerous situation of multiple drawers being pulled open at the same time, causing the center of gravity of the tool cart to become unstable and tip over.

[0044] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
