Description

Technical Field

[0001] The invention relates to a tool cabinet, in particular to an anti-overturning tool cabinet capable of preventing a plurality of drawers from being opened simultaneously. Background Art

[0002] At present, many tool cabinets have multiple layers of drawers, and tools are stored and retrieved by pulling out the drawers. When the drawers are closed, their center of gravity is located below the tool cabinet body, but when the drawers are open, their center of gravity will shift outward until it is outside the tool cabinet. The open drawers will form a torque on the tool cabinet body, and this torque will make the tool cabinet likely to overturn. When multiple drawers are open, the torque increases until it overturns. The overturning of the tool cabinet will cause the tools to fall and may also cause personal injury or death.

[0003] However, at present, in this type of tool cabinet with multiple drawers, the opening of each layer of drawers is independent of each other and does not interfere with each other. When taking tools, many people will open multiple drawers at the same time, which inevitably causes the tool cabinet to overturn.

[0004] The patent application with the invention patent application number 2022104006482 and the invention name of a drawer cabinet that prevents multiple drawers from being fully opened at the same time discloses a drawer cabinet, including a cabinet body, a drawer, a control rope and a fixed ring; a number of the drawers are slidably installed in the cabinet body, and a fixed ring is installed at the center of the back panel of each drawer; the control rope enters the cabinet body from the top of the cabinet back panel, passes through all the fixed rings in turn, and extends out of the cabinet body from the bottom of the cabinet back panel; the two ends of the control rope are respectively fixed on the cabinet back panel. However, the working condition of its limit block is unclear, and the control rope passes from the cabinet body to the outside of the cabinet body respectively, and is knotted outside the cabinet body, which affects the appearance. At the same time, there are safety hazards in the tool cabinet during movement. The control rope is in a loose state, which is not gentle enough when the drawer is pulled out, and there is also the problem of the control rope being entangled and knotted inside. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides an anti-overturning tool cabinet which can prevent multiple drawers from being opened at the same time, thereby avoiding opening multiple drawers at the same time and making the tool cabinet more stable.

For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0027] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. Example

[0028] like Figure 1-3 As shown, an anti-overturning tool cabinet that can prevent multiple drawers from being opened at the same time includes a cabinet body, a drawer that can slide on the cabinet body, and a bracket. The bracket is fixed to the cabinet body, a fixed wheel is fixedly installed on the bracket, and a moving wheel is fixedly connected to the drawer. The pull rope alternately passes around the fixed wheel and the moving wheel. After passing around the fixed wheel and the moving wheel, the pull rope still has a controlled length, and the controlled length is sufficient for one of the drawers to be opened.

[0029] like Figure 4-6 As shown in the figure, when a drawer is opened, the moving wheel moves with the drawer, thereby pulling the drawstring. When a drawer is fully opened, the control length after the drawstring is pulled is reduced to 0. At this time, if another drawer is to be opened, the moving wheel on the drawer must also pull the drawstring. Since the control length has become 0, the drawer must be pulled back to the drawstring on the originally opened drawer to open it. In this way, the originally opened drawer can be forcibly closed, avoiding the problem of two drawers being opened at the same time. Figure 7 shown.

[0030] When the drawer is not opened, the tension block is at the bottom. Figure 8 shown.

[0031] In order to avoid interference between the moving wheel pull rope and the drawer, the upper and lower positions of the fixed wheel are between the two drawers.

[0032] In order to make the force on the moving wheel more uniform, the moving wheel is located in the middle of the back plate of a drawer.

[0033] When fixing the pull rope, one end of the pull rope can be fixed on the moving wheel of the bottom drawer, or fixed on the back plate of the bottom drawer, or fixed on the fixed wheel of the bottom drawer, or directly fixed under the bracket, and the other end passes around the upper end surface of the bracket and is connected to the tension block, and the tension block tightens the pull rope. When the pull rope passes around the upper end surface of the bracket, a pulley can be set at the upper end surface to reduce friction.

[0034] In order to ensure that the tension block has a stable movement channel when the drawer is pulled out, a tension block slide groove is provided on the bracket, and the height of the tension block slide groove is greater than the thickness of the tension block.

[0035] In order to position the tension block, a positioning block is provided on the bracket to ensure that the length of the pull rope is sufficient for a drawer to be fully opened. The position of the positioning block can also be set to be adjustable. Example

[0036] On the basis of the first embodiment, the difference from the first embodiment lies in the different arrangement of the pull rope. Specifically, one end of the pull rope is fixed to the top drawer or the bottom drawer or its fixed wheel, and the other end is wound around the pull rope by a coil spring. When all drawers are closed, the control length is wound and contracted by the coil spring, and when a drawer is fully opened, the contracted control length in the coil spring is released, and the aforementioned technical effect can also be achieved.

[0037] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention.
