Description

Technical Field

[0001] This utility model relates to the field of cargo or equipment transportation and storage technology, specifically a stackable box suitable for short-distance transfer and multi-layer storage of various goods and equipment. Background Technology

[0002] Stackable crates are commonly used in the transportation and storage of goods or equipment, and their core requirements focus on three aspects: stacking stability, ease of movement, and reliable lid connection. However, existing technologies for traditional stackable crates have several shortcomings: Firstly, a single container is quite heavy when fully loaded with goods or equipment, lacks a convenient moving structure, and manual handling is laborious and inefficient. Secondly, when multiple boxes are stacked, they are positioned by only the contact surfaces of the upper and lower boxes, without a special locking structure. During transportation or storage, the stack is prone to tipping over due to vibration or collision, posing a safety hazard. Third, the connection between the lid and the body of the container is mostly a simple fastening or rope binding, which is not stable enough. The lid is easy to fall off during transportation, resulting in damage to the internal goods or equipment. Fourth, although some movable boxes are equipped with wheels at the bottom, the wheels can affect the fit when stacked, further reducing stacking stability.

[0003] Based on the shortcomings of the existing technology, this utility model proposes a solution to simultaneously meet the requirements of convenient movement, solid stacking, and reliable lid connection. Utility Model Content

[0004] The purpose of this invention is to provide a stacking box to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A stackable box, comprising a box body and a box lid, wherein at least one box lid is equipped with multiple casters at the bottom, and a second buckle is fixedly installed on the outer walls at both ends of the box near the bottom, the second buckle being used to fix the box lid to the bottom of the box body, a first buckle is fixedly installed on the outer walls at both ends of the box body near the top, and a second protruding frame is integrally formed on the bottom end of the outer wall of the box body, the first buckle being adapted to the box lid and the second protruding frame.

[0006] As a further embodiment of this utility model: a first protruding frame is integrally formed at the top opening of the box body, and a first positioning groove adapted to the first protruding frame is provided at the bottom of the box cover.

[0007] As a further embodiment of this utility model: the bottom of the box is integrally formed with a second positioning frame, the outer contour of the second positioning frame being adapted to the inner contour of the top opening of the box.

[0008] As a further improvement of this utility model: the top of the box cover is provided with a second positioning groove, which is adapted to the second positioning frame.

[0009] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model is convenient and safe to move. By installing casters at the bottom of the lid, the lid can be used to cover the box and also as a trolley. The casters have a self-locking function. When moving, the casters can be unlocked to achieve 360° flexible turning, which is suitable for transporting in narrow spaces. After moving to the designated position, the casters can be locked to prevent the box from sliding accidentally. It combines flexibility and safety. When transporting a single box, there is no need to carry it. It can be pushed by the casters on the lid, which greatly saves manpower and improves the efficiency of transport.

[0010] 2. This utility model provides stable stacking and multi-layer compatibility: When multiple boxes are stacked, the second positioning frame of the upper box can be accurately embedded into the top opening of the lower box or the second positioning groove of the lower box cover to form physical positioning; with the locking cooperation of the first buckle and the second protruding frame, the dual fixation of "positioning + locking" can be achieved, and multiple boxes can be stacked stably.

[0011] 3. The lid of this utility model is firmly connected: the lid is initially positioned on the first protruding frame of the box opening through the first positioning groove; then the lid is locked by the first buckle, which can ensure that the connection is firm and there is no looseness. This not only prevents the lid from falling off during transportation, but also reduces dust from entering the box and protects the cleanliness of the goods. Attached Figure Description

[0020] Please see Figures 1-3 In this embodiment of the utility model, a stacking box includes several storage boxes. Each storage box consists of a box body 1 and a box cover 2. At least one storage box has multiple casters 3 installed at the bottom of its box cover 2. The casters 3 are omnidirectional wheels with self-locking function. The load-bearing weight of a single caster 3 is not less than 50kg. The wheel surface is made of wear-resistant rubber material and has quiet and shock-absorbing performance. The outer walls at both ends of the storage box are fixedly installed with second buckles 10 near the bottom. The second buckles 10 are used to fix the box cover 2 to the bottom of the box body 1. The outer walls at both ends of the box body 1 are fixedly installed with first buckles 4 near the top. The bottom of the outer wall of the box body 1 is integrally formed with a second protruding frame 7. The first buckles 4 are adapted to the box cover 2 and the second protruding frame 7.

[0021] By adopting the above-described solution, this utility model allows the lid 2 to be fixedly installed at the top opening of the box body 1 by utilizing the cooperation of the first buckle 4 and the lid 2. The upper box body 1 can be fixed to the top of the lower box body 1 by utilizing the cooperation of the first buckle 4 and the second protruding frame 7. By installing casters 3 at the bottom of the lid 2, the lid 2 can be used to cover the box body 1 and also as a trolley. By utilizing the cooperation of the second buckle 10 and the lid 2, the lid 2 with casters 3 at the bottom can be fixed to the bottom of the matching box body 1, thereby facilitating the movement of the box body 1 and other boxes 1 stacked on it, making it more convenient to use.

[0022] Specific combination Figures 1-3 In one embodiment of the present invention, a first protruding frame 5 is integrally formed at the top opening of the box body 1, and a first positioning groove 6 adapted to the first protruding frame 5 is provided at the bottom of the box cover 2.

[0023] The cooperation between the first frame 5 and the first positioning groove 6 facilitates the positioning and installation of the cover 2 at the top of the box body 1. After the cover 2 is fixed to the top of the box body 1 using the first buckle 4, the reliability of the cover 2 installation can be ensured.

[0024] Specific combination Figure 2 and Figure 3 In one embodiment of the present invention, the bottom of the box 1 is integrally formed with a second positioning frame 8, and the outer contour of the second positioning frame 8 is adapted to the inner contour of the top opening of the box 1.

[0025] With the setting of the second positioning frame 8, when multiple boxes 1 are stacked, the second positioning frame 8 at the bottom of the upper box 1 can be inserted into the top opening of the lower box 1, so that after the second protruding frame 7 is fastened with the first buckle, the reliability of the connection between the two stacked boxes 1 can be ensured.

[0026] Specific combination Figure 3 In one embodiment of this utility model, a second positioning groove 9 is provided on the top of the box cover 2. The second positioning groove 9 is adapted to the second positioning frame 8. Through the cooperation of the second positioning groove 9 and the second positioning frame 8, the box body 1 can be positioned and installed on the box cover 2, thereby improving the reliability of the two after locking and preventing the box body 1 from sliding on the box cover 2.
