Description

Technical Field

[0001] This utility model belongs to the field of packaging wooden box technology, and in particular, an adjustable packaging wooden box. Background Technology

[0002] Wooden crates are packaging boxes assembled from wood that has undergone fumigation and insect-proofing treatment. They are widely used for packaging hazardous materials, primarily as cushioning and insulation. Wood is widely used in the packaging industry due to its excellent cushioning properties, high strength, corrosion resistance, and good moisture absorption. Wooden crates are the most common type of wooden packaging container. However, the fixed internal volume of existing wooden crates makes it impossible to adjust their internal dimensions, which is inconvenient for loading items of varying sizes.

[0003] A search of Chinese patent documents (authorization announcement number CN218199365U) reveals that this utility model belongs to the field of packaging wooden box technology, and particularly relates to an adjustable packaging wooden box, including a base plate and connecting parts. A first side wall box is installed on the base plate; a second side wall box is detachably installed on the first side wall box; a box lid is installed on the second side wall box; the connecting parts are used for detachable connection between the first side wall box and the second side wall box; wherein there are multiple second side wall boxes, which are stacked, and adjacent second side wall boxes are detachably connected by the connecting parts. By using the first side wall boxes and an appropriate number of second side wall boxes as needed, the size of the wooden box can be adjusted. The detachable connection by the connecting parts ensures that changing the size of the wooden box does not affect the stacking of the packaging wooden boxes. Furthermore, compared with the prior art, the maximum space is not limited by the height of the threaded rod, improving the convenience of use and practical effect. This device can meet basic usage needs, but it cannot adjust its internal volume, making it inconvenient to load items of different volumes. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable packaging wooden box to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable packaging wooden box, comprising a box body for packaging, wherein the top of the box body is provided with two double-circular limiting grooves for limiting sliding;

[0006] Two springs are symmetrically connected inside each of the two double-circular limiting grooves. The ends of the four springs are connected to double-circular sliders for sliding. Damping is provided between the four springs and the double-circular limiting grooves. The four double-circular sliders are slidably disposed inside the double-circular limiting grooves. Six guide posts for limiting are welded inside the double-circular limiting grooves. The six guide posts completely penetrate the double-circular sliders. Connecting blocks for connection are welded to the bottom of each double-circular slider.

[0007] Preferably, each of the four connecting blocks has a rotating shaft rotatably mounted inside, and two of the connecting blocks have semi-circular grooves at their bottoms.

[0008] Preferably, two of the rotating shafts are connected to adjusting fixing plates, and the other two rotating shafts are connected to adjusting fixing brackets, with the ends of the adjusting fixing plates rotatably disposed inside the semi-circular groove.

[0009] Preferably, a rotating column is rotatably mounted on the end of both the adjusting fixing plate and the adjusting fixing frame away from the rotating shaft, and a mating block for fixing is installed on the outer periphery of the rotating column.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] This adjustable packaging crate benefits from the structure of the adjusting bracket and adjusting plate. Pulling down the mating block moves the adjusting bracket and adjusting plate closer to the goods, securing them in place. Compared to traditional adjustable packaging crates that cannot adjust their internal volume, this design allows for greater stability in securing the goods. Pulling out the triangular fixing strip allows the mating block to enter the mating groove, which is then inserted into the triangular groove to secure it. This increases adjustability and adapts to goods of different sizes, avoiding the need to customize new crates due to changes in goods specifications, thus reducing the variety of crates and inventory costs.

[0015] This adjustable wooden crate, thanks to its spring and double-circular slider structure, allows for automatic reset when no fixation is needed. The triangular fixing bar is pulled out of the triangular groove, the mating block separates from the groove, the spring causes the double-circular slider to separate, and the adjusting fixing plate and adjusting fixing bracket return to the inner top wall of the crate. This structure allows for easy operation. Attached Figure Description

Detailed Implementation

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0026] like Figures 1 to 5 An adjustable packaging wooden box is shown, including a box body 1 for packaging, and two double circular limiting grooves 2 are provided on the top of the box body 1 to limit sliding.

[0027] Two springs 201 are symmetrically connected inside each of the two double circular limiting grooves 2. The ends of the four springs 201 are all connected to double circular sliders 203 for sliding. Damping is provided between the four springs 201 and the double circular limiting grooves 2. The damping can be cylindrical / ring-shaped, adapted to the circular limiting grooves, and can provide damping force in the radial or axial direction. The structure is compact. The damping can absorb the vibration energy generated during the compression / tension of the springs 201 and avoid system resonance caused by the elastic oscillation of the springs 201. The damping is existing technology and is not an innovative direction for this adjustable packaging wooden box, so it will not be described in detail. The springs 201 are consumables and need to be replaced regularly to prevent the springs 201 from failing. Four double-circular sliders 203 are slidably disposed inside the double-circular limiting groove 2. Six guide posts 202 for limiting are welded inside the double-circular limiting groove 2. The six guide posts 202 completely penetrate the double-circular sliders 203. Connecting blocks 204 for connection are welded to the bottom of each double-circular slider 203. Rotating shafts 205 are rotatably installed inside each of the four connecting blocks 204. The bottom of two of the connecting blocks 204 is provided with semi-circular grooves. When the mating block 301 moves downward, the adjusting fixing plate 206 and the adjusting fixing bracket 207 respectively drive the two connecting blocks 204 and the double-circular sliders 203 to move closer. The double-circular sliders 203 drive the spring 201 to deform and the spring 201 to extend. When no fixation is required, the triangular fixing strip 103 is pulled out of the triangular groove 302, the mating block 301 separates from the mating groove 102, the spring 201 drives the double-circular sliders 203 to separate, and the adjusting fixing plate 206 and the adjusting fixing bracket 207 return to the inner top wall of the box 1.

[0028] Two of the rotating shafts 205 are connected to adjusting fixing plates 206, and the other two rotating shafts 205 are connected to adjusting fixing brackets 207. The end of the adjusting fixing plate 206 is rotatably set inside the semi-circular groove. The ends of the adjusting fixing plate 206 and the adjusting fixing bracket 207 away from the rotating shafts 205 are both rotatably mounted with rotating columns 3. The outer periphery of the rotating column 3 is equipped with a fixing block 301. The interior of the fixing block 301 is provided with a triangular groove 302 for connection. When the goods to be fixed are placed into the box 1, the fixing block 301 is pulled down. The fixing block 301 drives the adjusting fixing bracket 207 and the adjusting fixing plate 206 to move closer to the goods. The adjusting fixing plate 206 and the adjusting fixing bracket 207 fix the goods.

[0029] The inner bottom wall of the box body 1 is provided with multiple mating grooves 102 for mating with mating blocks 301. Triangular fixing strips 103 for adjustment and fixation are slidably installed inside the mating grooves 102. Multiple reinforcing strips 101 for reinforcing the box body 1 are installed on the outer periphery of the box body 1. A door for opening and closing is installed on the side of the box body 1. When the triangular fixing strips 103 are pulled out, the mating blocks 301 enter the mating grooves 102. The triangular fixing strips 103 are inserted into the triangular grooves 302 and the triangular grooves 302 are fixed, thereby increasing the stability of the goods being fixed by the adjusting fixing plate 206 and the adjusting fixing bracket 207.

[0030] Working principle

[0031] When using this adjustable wooden crate, first place the goods to be secured inside the crate body 1. Pull down the mating block 301. The mating block 301 moves the adjusting fixing bracket 207 and the adjusting fixing plate 206 closer to the goods. The adjusting fixing plate 206 and the adjusting fixing bracket 207 secure the goods. Pull out the triangular fixing strip 103. The mating block 301 enters the mating groove 102. Insert the triangular fixing strip 103 into the triangular groove 302 and fix the triangular groove 302. The adjusting fixing plate 206 and the adjusting fixing bracket 207 further secure the goods. To ensure the stability of the fixed object, when the mating block 301 moves downward, the adjusting fixing plate 206 and the adjusting fixing bracket 207 respectively drive the two connecting blocks 204 and the double circular slider 203 to move closer. The double circular slider 203 drives the spring 201 to deform and the spring 201 to extend. When no fixation is needed, the triangular fixing strip 103 is pulled out of the triangular groove 302, the mating block 301 separates from the mating groove 102, the spring 201 drives the double circular slider 203 to separate, and the adjusting fixing plate 206 and the adjusting fixing bracket 207 return to the inner top wall of the box 1.
