Description

Technical Field

[0001] This utility model relates to the field of enclosed box technology, specifically to an anti-loosening locking mechanism for enclosed boxes. Background Technology

[0002] Collapsible crates are a special type of packaging container, mainly used in industrial and logistics fields. In order to quickly fix collapsible crates, a base and top cover adapted to the collapsible crate are usually used for fixation. For reference, see the relevant patent CN205023064U. Essentially, it is a rectangular space for storage formed by the cooperation of multiple collapsible panels and connecting plates.

[0003] From the perspective of portability and enhancing overall strength of collapsible crates: foldable collapsible crates are superior to fixed collapsible crates in terms of overall portability and practicality. However, due to their inherent structural characteristics, their strength is usually not high. If not properly secured, the entire crate can easily fall apart during transportation. Therefore, in addition to achieving portability, it is also necessary to consider adding locking devices to the top cover and base to ensure that these devices do not accidentally come apart. To this end, we provide an anti-loosening collapsible crate locking mechanism to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a locking mechanism for a panel box that prevents loosening, so as to solve the problems mentioned in the background art.

[0006] A locking mechanism for a panel box that prevents loosening includes a base plate, a base unit for locking the panel is provided on the top surface of the base plate, and a top cover unit that can be quickly fixed and disassembled is provided on the top surface of the base unit.

[0007] The base unit includes a base fixed to the top surface of the base plate, a bidirectional threaded rod rotatably connected inside the bottom surface of the base for quick adjustment, and a locking block slidably connected inside the base for limiting position.

[0008] The top cover unit includes a top cover disposed on the top surface of the base for sealing, and a sliding latch rod slidably connected inside the base for engaging the surrounding panel.

[0009] A further improvement of this utility model is that a surrounding box is movably connected to the top surface of the base, and multiple slots are provided on the side of the surrounding box.

[0010] A further improvement of this utility model is that: a turntable is fixedly connected to the side of the bidirectional threaded rod, a locking nut is threaded to one end of the outer surface of the bidirectional threaded rod, and two threaded sliders with opposite directions are threaded to the outer surface of the bidirectional threaded rod.

[0011] A further improvement of this utility model is that: a pull rod is movably connected to the side of the threaded slider, the locking block is movably connected to the side of the pull rod, and the locking block is engaged inside the locking slot.

[0012] A further improvement of the present invention is that: a slot is provided on the bottom surface of the top cover, the slot is engaged with the top of the outer surface of the enclosure box, and a bracket is fixedly connected to the bottom surface of the top cover.

[0013] A further improvement of this utility model is that: one end of the sliding lever is engaged inside another slot, a rack is fixedly connected to the side of the sliding lever, and an adjusting gear is movably connected to the side of the rack.

[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0023] The present invention will be further described in detail below with reference to embodiments:

[0024] Example 1: As Figure 1-5 As shown, this utility model provides a locking mechanism for a panel box that prevents loosening, including a base plate 1. The top surface of the base plate 1 is provided with a base unit 2 for locking the panel. The top surface of the base unit 2 is provided with a top cover unit 3 that can be quickly fixed and disassembled. The base unit 2 includes a base 21 fixed to the top surface of the base plate 1, a bidirectional threaded rod 24 rotatably connected to the bottom surface of the base 21 for quick adjustment, and a locking block 29 slidably connected to the bottom surface of the base 21 for limiting the position. The top surface of the base 21 is movably connected to a panel box 22, and the side of the panel box 22 is provided with multiple slots 23.

[0025] The top and bottom sides of the enclosure box 22 are provided with multiple latches 23. The inside of the latch 29 is provided with a limiting groove to prevent the latch 29 from moving excessively, and it is engaged in the internal latch rod of the base 21. The locking nut 26 can be removed to avoid affecting the normal operation of the bidirectional threaded rod 24. The surface of the bidirectional threaded rod 24 is provided with two sections of threads in opposite directions, and its middle part is fixed in the middle of the base 21 to ensure its stability.

[0026] A turntable 25 is fixedly connected to the side of the bidirectional threaded rod 24. A locking nut 26 is threadedly connected to one end of the outer surface of the bidirectional threaded rod 24. Two threaded sliders 27 with opposite directions are threadedly connected to the outer surface of the bidirectional threaded rod 24. A pull rod 28 is movably connected to the side of the threaded slider 27. A locking block 29 is movably connected to the side of the pull rod 28 and is locked inside the bayonet 23.

[0027] Two sets of threaded sliders 27 are installed on the outer surface of the bidirectional threaded rod 24 in opposite directions. At the same time, the pull rod 28 provided on the side of the threaded sliders 27 drives the locking block 29 to extend and retract inside the base 21.

[0028] In this embodiment, by installing the unfolded enclosure box 22 inside the preset slot on the top surface of the base 21, the locking nut 26 that limits the bidirectional threaded rod 24 is removed. The locking nut 26 is rotated by rotating the turntable 25. Under the action of the two opposite threads on the surface of the locking nut 26, the threaded slider 27 moves relative to each other. The movement of the threaded slider 27 will cause the pull rod 28 to change its own angle. Furthermore, the pull rod 28 pushes out the locking block 29, so that the locking block 29 is engaged inside the slot 23 at the bottom side of the enclosure box 22, thus limiting the enclosure box 22.

[0029] Example 2: As Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the top cover unit 3 includes a top cover 31 disposed on the top surface of the base 21 for sealing, and a sliding rod 34 slidably connected inside the base 21 for engaging the surrounding panel. The bottom surface of the top cover 31 is provided with a slot 33, which engages with the top of the outer surface of the surrounding panel box 22. A bracket 32 ​​is fixedly connected to the bottom surface of the top cover 31. One end of the sliding rod 34 is engaged inside another slot 23. A rack 35 is fixedly connected to the side of the sliding rod 34, and an adjusting gear 36 is movably connected to the side of the rack 35.

[0030] The bracket 32 ​​strengthens the overall strength of the slot 33. The sliding rod 34 passes through the inside of the slot 33. There are two sliding rods 34 in opposite directions. The two sliding rods 34 are designed to prevent excessive displacement. The top side of the adjusting gear 36 is provided with a fixing buckle that is fixed to the top surface of the base 21 by bolts.

[0031] In this embodiment, after the bottom surface of the enclosure box 22 is fixed, the bracket 32 ​​is installed on the top surface of the enclosure box 22, and the slot 33 is secured to the top of the outer surface of the enclosure box 22. At this time, the two racks 35 at the bottom of the outer surface of the adjusting gear 36 can be rotated to drive relative movement. One end of the sliding rod 34 passes through the slot 33 to fix the top side slot 23 of the enclosure box 22. At this time, the enclosure box 22 is firmly fixed, and the top surface of the adjusting gear 36 can be fixed with bolts to ensure that the top cover unit 3 will not fall off accidentally.

[0032] The working principle of the anti-loosening enclosure box locking mechanism will be explained in detail below.

[0033] like Figure 1-5As shown, the collapsible box 22 in its stored state can be placed between the base unit 2 and the top cover unit 3. At this time, the entire device is a regular flat cuboid, reducing its space occupation. When it is necessary to support the collapsible box 22, the base unit 2 can be used to quickly fix and lock the bottom surface of the collapsible box 22, and the top cover unit 3 can be used to fix the top surface of the collapsible box 22. Through the cooperation of the base unit 2 and the top cover unit 3, the overall stability of the collapsible box 22 is ensured.

[0034] The unfolded enclosure box 22 is installed inside the pre-set slot on the top surface of the base 21. At this time, the locking nut 26 that limits the bidirectional threaded rod 24 is removed. The locking nut 26 is rotated by rotating the turntable 25. Under the action of the two opposite threads on the surface of the locking nut 26, the threaded slider 27 moves relative to each other. The movement of the threaded slider 27 will cause the pull rod 28 to change its own angle. The pull rod 28 will push out the locking block 29, so that the locking block 29 is engaged inside the slot 23 at the bottom side of the enclosure box 22, thus limiting the enclosure box 22.

[0035] After the bottom of the enclosure box 22 is fixed, the bracket 32 ​​is installed on the top surface of the enclosure box 22, ensuring that the slot 33 can be engaged with the top of the outer surface of the enclosure box 22. At this time, the two racks 35 at the bottom of the outer surface of the adjusting gear 36 can be driven to move relative to each other by rotating the adjusting gear 36. One end of the sliding rod 34 passes through the slot 33 to fix the top side slot 23 of the enclosure box 22. At this time, the enclosure box 22 is firmly fixed. The top surface of the adjusting gear 36 can be fixed with bolts to ensure that the top cover unit 3 will not fall off accidentally.

[0036] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all modifications or improvements made without departing from the spirit and concept of the present invention are within the protection scope of the present invention.
