Description

Technical Field

[0001] This invention relates to the field of auxiliary mobility technology for portable heavy-duty cabinet display devices, specifically a quick-installation load-bearing mobility device for heavy-duty cabinet equipment and its usage method. Background Technology

[0002] Existing heavy-duty case display equipment is quite heavy, making manual handling and long-distance dragging laborious. It is also prone to fatigue and damage after long-term use. Furthermore, the commonly used luggage handles on the market cannot meet the load-bearing requirements of heavy industrial cases, have poor connection structure stability, and are prone to detachment and breakage.

[0003] While competitors offer similar cabinet products, none have a dedicated upper and lower layered locking and linkage structure specifically designed for heavy-duty cabinet display devices. This means the cabinet cannot be used independently without the moving device, resulting in concentrated dragging force at a single point, poor load reduction, and a cumbersome assembly / disassembly process. Furthermore, the generic pull rod structure is easily copied and circumvented by competitors, failing to create a unique technological barrier. Therefore, the inventor proposes a quick-assembly, load-bearing moving device for heavy-duty cabinet equipment and its usage method. Summary of the Invention

[0004] The purpose of this invention is to provide a quick-assembly load-bearing mobile device for heavy-duty box-type equipment and its usage method. The device has a simple structure and reasonable design. The device uses a fixed buckle body to bear the entire vertical weight and vertical load-bearing tension of the heavy-duty box-type equipment, thereby distributing the force and reducing the burden of dragging. Then, the movable buckle body implements lateral locking and limiting of the heavy-duty box-type equipment to prevent the heavy-duty box-type equipment from shaking or falling off during dragging. This greatly reduces the burden of dragging heavy objects. At the same time, it has the advantages of being two-in-one and easy to assemble and disassemble, forming a unique technical barrier from the perspective of connection principle, and solving the problems mentioned in the above technical background.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a quick-assembly load-bearing moving device for heavy-duty box-type equipment. This device includes a main support frame and fixed load-bearing buckles and movable locking buckles respectively disposed at both ends of the main support frame. Two main support frames are provided, and a moving mechanism is provided at the end of each main support frame away from the movable locking buckle. The fixed load-bearing buckle includes a support base and a lower protruding beam fixed to the support base. A fixed buckle body is detachably mounted on the lower protruding beam. The fixed buckle body includes a load-bearing strip, a central protrusion fixed to the load-bearing strip, and two edge protrusions, wherein the two edge protrusions are symmetrically arranged. The movable locking buckle is located at both ends of the central protrusion; it includes a suspension plate and an upper protruding beam fixed to the end of the suspension plate away from the support base. The movable buckle body is detachably installed on the upper protruding beam. The structure of the movable buckle body is the same as that of the fixed buckle body. The suspension plate is set on the handle. Movable supports are fixed at both ends of the handle. An adapter groove is provided through the handle. The suspension plate is inserted into the adapter groove and is in contact with the inner wall of the adapter groove. The two movable supports are slidably set on the two main support frames respectively. The moving mechanism includes two rotating shafts and load-bearing wheels respectively installed on the two rotating shafts. The two rotating shafts are respectively set at both ends of the fixed load-bearing buckle.

[0006] Preferably, a first slot is formed on the lower protruding beam along its length direction. The load-bearing bar is inserted into the first slot and is in contact with the inner wall of the first slot to ensure that the load-bearing bar will not shake. Both sides of the first slot are provided with protruding outlets, and the two ends of the load-bearing bar pass through the two protruding outlets respectively. A first locking groove is provided on the side of the first slot away from the support base, and a positioning protrusion is fixed in the first slot. The first locking groove and the positioning protrusion are distributed on both sides of the first slot, and the central protrusion is inserted into the first locking groove.

[0007] Preferably, a central insertion hole is formed on the central boss, and edge insertion holes are formed on both edge bosses. The load-bearing connector on the heavy-duty box equipment has three matching cylindrical heads, which are inserted into the central insertion hole and the two edge insertion holes, so that the box equipment is just confined to the load-bearing bar.

[0008] Preferably, both ends of the support base are fixed with fixed supports, the two main support frames are respectively fixed to the upper end face of the two fixed supports, the ends of the two fixed supports that are far apart from each other are provided with shaft mounting holes, the two rotating shafts are respectively installed in the two shaft mounting holes, and the two rotating shafts can rotate on the two fixed supports respectively.

[0009] Preferably, a second slot is formed on the upper protruding beam along its length direction. The movable buckle body is in contact with the inner wall of the second slot. A second locking groove is provided at the center of the second slot. Since the structure of the movable buckle body is the same as that of the fixed buckle body, and its installation method is also the same as that of the fixed buckle body, the structure at the center of the movable buckle body is just inserted into the second locking groove, so that the movable buckle body is confined in the second slot and will not shake.

[0010] Preferably, the suspension plate and the upper protruding beam form an L-shape, with the upper protruding beam contacting and connecting with the upper end face of the handle.

[0011] Preferably, both ends of the suspension plate are fixed with positioning angles, and both positioning angles are in contact with the lower end face of the hanging handle. The upper protruding beam cooperates with the two positioning angles, so that the whole consisting of the suspension plate and the upper protruding beam can be suspended on the hanging handle.

[0012] Preferably, each of the two movable supports has a groove at one end near the fixed load-bearing buckle. The two main support frames are slidably disposed in the two grooves, and the two main support frames are in contact with the inner walls of the two grooves respectively. At the same time, the tops of the two main support frames are confined within the grooves and cannot be removed from the grooves, so as to prevent the main support frames from separating from the movable locking buckle.

[0013] Preferably, the end of the movable locking buckle away from the two main support frames is connected to a secondary support frame. The secondary support frame includes a support frame body fixed to the upper surface of the two movable supports. The support frame body is U-shaped, and a rubber sleeve is fixedly fitted to the end of the support frame body away from the two movable supports.

[0014] A method of using the aforementioned quick-assembly load-bearing mobile device for heavy-duty box-type equipment, the method comprising the following steps: ① When leaving the factory, the heavy-duty box equipment has two sets of symmetrically arranged load-bearing connectors for locking. Each set of load-bearing connectors has three cylindrical heads. The heads on the two sets of load-bearing connectors are inserted into the corresponding center holes and two edge holes, so that the two ends of the heavy-duty box equipment are respectively limited to the fixed buckle body and the movable buckle body. The two ends of the heavy-duty box equipment are respectively in contact with the fixed buckle body and the movable buckle body, so that the heavy-duty box equipment is suspended on the fixed buckle body and the movable buckle body.

[0015] ② The operator holds the rubber sleeve and tilts the entire device to a certain extent so that the two load-bearing wheels contact the ground. Then, the operator can pull the entire assembly consisting of the main support frame, the fixed load-bearing buckle, and the movable locking buckle, so that the entire assembly moves with the rolling of the two load-bearing wheels, thereby greatly reducing the load when operating heavy-duty box-type equipment.

[0016] ③ During the movement, the fixed buckle body bears the entire vertical weight and vertical load-bearing tension of the heavy box equipment, realizing the distribution of force and reducing the burden of dragging. Then, the movable buckle body implements lateral locking and limiting of the heavy box equipment to prevent the heavy box equipment from being dragged, shaking, loosening and falling off.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention provides a quick-assembly load-bearing moving device for heavy-duty box-type equipment and its usage method. The device includes a main support frame and fixed load-bearing buckles and movable locking buckles respectively disposed at both ends of the main support frame. Two main support frames are provided.

The fixed buckle body is detachably installed on the lower protruding beam. The movable locking buckle includes a suspension plate and an upper protruding beam fixed to the end of the suspension plate away from the support base. The movable buckle body is detachably installed on the upper protruding beam. The fixed buckle body bears the entire vertical self-weight and vertical load-bearing tension of the heavy-duty box-type equipment, realizing force distribution and labor-saving and load-reducing dragging. The movable buckle body implements lateral locking and limiting of the heavy-duty box-type equipment to prevent the heavy-duty box-type equipment from dragging, shaking, loosening and falling. It is suitable for widespread use.

[0018] 2. The fixed buckle body and the movable buckle body in this invention achieve a significant reduction in load when dragging heavy objects. The heavy-duty box equipment and this device can be used together or separately. No screws or tools are required for disassembly and assembly. The operation logic is simple and efficient, and the disassembly and assembly process is relatively convenient and highly practical.

[0019] 3. When using this invention, the load-bearing connecting parts on the heavy-duty box equipment are exclusive point structures pre-embedded at the factory. The load-bearing connecting parts are only compatible with the fixed buckle body and the movable buckle body of this device, and are not compatible with the luggage handles commonly used in the market. Moreover, the disassembly and assembly logic is unique, which can form an exclusive technical barrier from the perspective of connection principle. Attached Figure Description
