[0003] Existing plastic boxes have a fixed internal space after injection molding. When storing different objects, it is inconvenient to adjust the internal space of the plastic box according to the size of the objects, making it inconvenient to use.

[0004] Therefore, this application provides a space-adjustable multifunctional plastic box to solve the above problems. Utility Model Content

[0005] This application provides a space-adjustable multifunctional plastic box, which aims to solve the problem mentioned in the background art that the internal space of existing plastic boxes is fixed after injection molding, making it inconvenient to adjust the internal space of the plastic box according to the size of different objects when storing them, thus causing inconvenience in use.

[0006] To achieve the above objectives, this application provides the following technical solution: a multi-functional plastic box with adjustable space, comprising a box body, a box cover on the top of the box body, and an adjustment mechanism inside the box body;

[0007] Preferably, to address the problem that existing plastic boxes have a fixed internal space after injection molding, making it inconvenient to adjust the internal space according to the size of different objects, the adjustment mechanism includes an operating groove located at the center of the bottom surface inside the box. A dual-axis motor is positioned at the center of the operating groove, and a threaded rod is fixedly connected to the output end of the dual-axis motor. A movable block is positioned outside the threaded rod, and a connecting block one is fixedly connected to the top of the movable block. An adjusting rod is positioned inside the connecting block one, and a connecting block two is positioned outside one end of the adjusting rod. A lifting block is fixedly connected to the top of the connecting block two, and the lifting block is slidably connected to the box. The dual-axis motor drives the threaded rod to rotate inside the operating groove, and the threaded rod is threadedly connected to the movable block, thereby allowing the movable block to rotate. The block slides inside the operating slot under force, moving the block and driving the top connecting block one to move. Connecting block one is rotatably connected to the adjusting rod, causing the adjusting rod to rotate around connecting block one as the pivot point. One end of the adjusting rod is rotatably connected to connecting block two, causing connecting block two to be forcefully pushed to slide the lifting block inside the box. The sliding fixed block compresses the spring and damper on the side, causing the fixed block to separate from the fixed slot, pushing the partition plate two, causing the partition plate two to drive the sliding block to slide outside the guide rod. The distance between the partition plates two can be adjusted according to the size of the object. The fixed block is subjected to the rebound force of the spring and damper, causing the fixed block to insert into the fixed slot, thus fixing the partition plate two. This allows for easy adjustment of the internal space of the box and easy adjustment of the partitions according to the size of the stored objects. It is convenient to adjust and use, simple and quick to operate, and easy to use.

[0008] Preferably, to address the issue of ease of use of the movable block, the threaded rod is rotatably connected to the operating groove, and the threaded rod is threadedly connected to the movable block. Two sets of movable blocks are symmetrically arranged inside the operating groove, and the movable block is slidably connected to the operating groove. The threaded rod is rotatably connected to the operating groove, and the threaded rod is threadedly connected to the movable block. The external threads of the threaded rod are opposite in direction, thereby allowing the movable block to slide within the operating groove under force, which can improve the stability of the movable block's movement.

[0009] Preferably, in order to solve the problem of convenient space adjustment, one end of the adjusting rod is rotatably connected to connecting block one, and the other end of the adjusting rod is rotatably connected to connecting block two. Both ends of the adjusting rod are rotatably connected to connecting block one and connecting block two respectively, so as to facilitate the raising and lowering of the lifting block, conveniently adjust the internal space of the box, and make it easy to use.

[0010] Preferably, to address the issue of convenient adjustment of the second partition plate, the top of the lifting block is fixedly connected to the first partition plate, and a guide rod is fixedly connected inside the slot at the bottom of the first partition plate. Multiple sets of sliding blocks are slidably connected to the outside of the guide rod, and the second partition plate is fixedly connected to both sides of the multiple sets of sliding blocks. The second partition plate drives the sliding blocks to slide outside the guide rod set in the bottom slot of the second partition plate, thereby facilitating the adjustment of the distance between the second partition plates and making it convenient to use.

[0011] Preferably, in order to solve the problem of fixing the first partition plate and the second partition plate, the top of the second partition plate is provided with a sliding groove, and a fixing block is slidably connected inside the sliding groove. The top sides of the first partition plate are provided with a number of fixing grooves that are adapted to the fixing blocks. The fixing blocks are inserted into the fixing grooves. By inserting the fixing blocks into the fixing grooves, the second partition plate and the first partition plate can be easily fixed, which is convenient to use.

[0012] Preferably, in order to solve the problem of convenient operation of the fixing block, a spring is fixedly connected between the side of the fixing block and the sliding groove, and a damper is fixedly connected between the side of the fixing block and the sliding groove. The spring is set outside the damper. When the fixing block slides inside the sliding groove, the fixing block compresses the spring set on the side. The fixing block can be easily restored to its original shape by means of the spring.

[0013] This adjustment mechanism uses a dual-axis motor to drive a threaded rod to rotate inside the operating slot. The threaded rod is threadedly connected to a moving block, causing the moving block to slide within the operating slot. The moving block moves a top-mounted connecting block, which is rotatably connected to an adjusting rod, causing the adjusting rod to rotate around the connecting block. One end of the adjusting rod is rotatably connected to a second connecting block, causing the second connecting block to slide a lifting block inside the housing. This slides a fixed block, compressing a spring and damper on its side, separating the fixed block from the fixed slot. This pushes a second partition plate, causing it to slide a sliding block outside the guide rod. The distance between the second partition plates can be adjusted according to the size of the objects. The fixed block, subjected to the rebound force of the spring and damper, engages with the fixed slot, thus fixing the second partition plate. This allows for easy adjustment of the internal space of the housing and convenient adjustment of the partitions according to the size of the stored objects. It is easy to adjust and use, simple and quick to operate, and convenient to use. Attached Figure Description
