Description

Technical Field

[0001] This utility model relates to the field of toolboxes, and in particular to a flip-type toolbox. Background Technology

[0002] With the increasing needs of people's lives and production, toolboxes have become increasingly widely used in daily life. Toolboxes generally have doors, allowing users to access the tools inside. Existing toolbox doors typically consist of two panels that open outwards. This opening method requires the panels to occupy space outside the toolbox, making it difficult to open in confined spaces. Additionally, there are folding or roller shutter doors, which, while convenient, are complex, expensive, and prone to damage. Based on these issues, our company previously developed a toolbox door (CN201333689Y) that is a top-opening door. While convenient and reliable, over time, the gap widens when the door is closed, and creaking noises frequently occur. To address this issue, our company further developed a toolbox flip-type door (CN 221646748 U). While this door solved the noise problem, it was found during use that with repeated pushing and pulling of the door over a long period, the lower edge of the connection between the door and the triangular connecting plate would loosen due to uneven stress over time. In severe cases, the entire door could even become loose, affecting its lifespan. Utility Model Content

[0003] The main technical problem solved by this utility model is to provide a flip-type toolbox that can ensure the long-term stability of the flip-up action and will not produce abnormal noise or loosening problems.

[0004] To solve the above-mentioned technical problems, the present invention provides a flip-type toolbox, which includes a box body and a flip-type door. The lower edge of the flip-type door folds outward to form a strip handle. The flip-type door is connected to the box walls on both sides of the box body through two symmetrically arranged flip-type drive mechanisms. Each flip-type drive mechanism includes a flipping arm and a horizontal guide rail. A rotating shaft is provided in the middle area of ​​the inner side of the box wall. One end of the flipping arm is rotatably hung on the inner side of the box wall through the rotating shaft. The other end of the flipping arm is provided with a hinge joint. The hinge joint is hinged to the middle of the corresponding side of the flip-type door. The horizontal guide rail is installed on the top of the corresponding side box wall. A guide wheel is installed in the horizontal guide rail. The axle of the guide wheel is fixed to the top of the flip-type door.

[0005] In a preferred embodiment of this utility model, the flip-door driving mechanism further includes an assist cylinder, the tail end of which is rotatably mounted on the box wall. The top end of the telescopic rod of the assist cylinder is movably connected to the flipping arm. A hinge shaft is provided at the connection position between the telescopic rod and the flipping arm. An arc-shaped clearance groove is provided on the box wall corresponding to the running trajectory of the hinge shaft. One end of the hinge shaft passes through the flipping arm and inserts into the arc-shaped clearance groove. When the flipping arm drives the hinge shaft to move to the lower end of the arc-shaped clearance groove, the guide wheel is located at the outer end of the horizontal guide rail, which is the closed state. When the flipping arm drives the hinge shaft to move to the top end of the arc-shaped clearance groove, the guide wheel is located at the inner end of the horizontal guide rail, which is the open state.

[0006] In a preferred embodiment of this utility model, a hollow groove is provided on the flipping arm near the hinge joint, and a pressure roller is installed in the hollow groove, with the wheel surface of the pressure roller pressing against the surface of the box wall.

[0007] In a preferred embodiment of this utility model, bullseye balls are symmetrically installed on both sides of the upper end of the flip door. The bullseye balls are installed below the guide wheel, and the rolling surface of the bullseye balls presses against the surface of the box wall.

[0008] In a preferred embodiment of this utility model, two vertical limiting blocks are symmetrically installed on both sides of the toolbox's bottom plate where they connect to the box wall. Each vertical limiting block has a rubber pad on its surface. When the flip door is closed, the lower edges of the flip door simultaneously abut against the two vertical limiting blocks. Rubber pads are installed on the abutting surfaces of the vertical limiting blocks.

[0009] The beneficial effects of this utility model are: This utility model is a further improvement on the flip-door drive structure of the company's existing products. By using the existing structure, on the one hand, the flip-door action can remain stable during long-term use without any squeaking noise. On the other hand, the uneven force on the connection position will not be caused by repeated lifting of the handle, effectively reducing the occurrence of local loosening at the connection position, and further improving the stability and service life of the door structure.

[0011] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0012] Please see Figures 1 to 4 The embodiments of this utility model include: A flip-type toolbox includes a box body and a flip-type door 1. The lower edge of the flip-type door 1 folds outward to form a strip handle 101. The flip-type door 1 is connected to the box walls 2 on both sides of the box body through two symmetrically arranged flip-type drive mechanisms. Each flip-type drive mechanism includes a flipping arm 4 and a horizontal guide rail 201. A rotating shaft 401 is provided in the middle area of ​​the inner side of the box wall 2. One end of the flipping arm 4 is rotatably hung on the inner side of the box wall 2 through the rotating shaft 401. The other end of the flipping arm 4 is provided with a hinge joint 402. The hinge joint 402 is hinged to the middle of the corresponding side of the flip-type door 1. The horizontal guide rail 201 is installed on the top of the corresponding side box wall 2. A guide wheel 103 is installed in the horizontal guide rail 201. The axle of the guide wheel 103 is fixed to the top of the flip-type door 1.

[0013] The flap drive mechanism also includes a power-assisted cylinder 3, the tail end of which is rotatably mounted on the box wall 2. The top end of the telescopic rod of the power-assisted cylinder is movably connected to the flip arm 4. By installing the power-assisted cylinder 3, on the one hand, the force required to open the flap door 1 can be reduced; on the other hand, during the opening process, the flap door 1 can be paused at any angle with the support of the power-assisted cylinder 3.

[0014] A hinge shaft 403 is provided at the connection position between the telescopic rod and the flipping arm 4. An arc-shaped clearance groove 202 is provided on the box wall 2 corresponding to the running trajectory of the hinge shaft 403. One end of the hinge shaft 403 passes through the flipping arm 4 and is inserted into the arc-shaped clearance groove 202. Thus, when the flipping arm 4 drives the hinge shaft 403 to move to the lower end of the arc-shaped clearance groove 202, the guide wheel 403 is located at the outer end of the horizontal guide rail 201, which is the closed state. When the flipping arm 4 drives the hinge shaft 403 to move to the top of the arc-shaped clearance groove 202, the guide wheel 403 is located at the inner end of the horizontal guide rail 201, and the entire flip door 1 is parallel to the bottom of the toolbox, which is the open state.

[0015] A perforated groove is provided on the tilting arm 4 near the hinge joint 402. A pressure roller 404 is installed in the perforated groove, and the wheel surface of the pressure roller 404 presses against the surface of the box wall 2. By installing the pressure roller 404, it can support the tilting arm 4 from both ends together with the rotating shaft 401, thereby improving the stability of the tilting arm 4 during rotation and preventing the tilting arm 4 from shaking and causing abnormal noise.

[0016] The upper sides of the flap door 1 are symmetrically equipped with bullseye ball bearings 102, which are installed below the guide wheel 103. The rolling surface of the bullseye ball bearings 102 presses against the surface of the box wall 2. In this way, during the flipping process, the bullseye ball bearings 102 and the guide wheel 103 work together to keep the distance between the flap door 1 and the box wall 2 constant, preventing the flap door 1 from swaying left and right, improving the stability of the flipping process, reducing noise, and extending the service life of the flap door 1.

[0017] Two vertical limiting blocks 5 are symmetrically installed on both sides of the bottom plate of the toolbox at the connection position with the box wall 2. Each vertical limiting block 5 has a rubber pad installed on its surface. When the flip door 1 is closed, the lower edge of the flip door 1 abuts against the two vertical limiting blocks 6 simultaneously. In this way, when the flip door 1 is closed, the vertical limiting blocks 5 can block the flip door 1 and prevent the flip door 1 from flipping inward, and the rubber pads can buffer the pressure at the abutment position.
