Description

Technical Field

[0001] This application relates to the field of furniture technology, and in particular to lightweight metal wardrobe frames that are easy to move. Background Technology

[0002] Many families now choose lightweight metal wardrobe frames that take up less space. Unlike traditional wooden wardrobes, they no longer require multiple people to lift them and carry them safely. Simply remove the bolts on the metal wardrobe frame to disassemble it into multiple metal tubes for easy transport.

[0003] However, frequent disassembly and installation of bolts can easily lead to slippage and failure due to wear. Furthermore, since there are many metal tubes in the metal wardrobe frame, disassembly and installation require more time for those unfamiliar with the specific structure. This undoubtedly increases the time cost for operators. In addition, the weight of multiple stacked metal tubes is also considerable, requiring more physical effort from the movers. If multiple metal tubes are moved in batches, it will require even more back-and-forth movements, wasting even more time. Utility Model Content

[0004] This application proposes a lightweight metal wardrobe frame that is easy to transport. It has the advantages of allowing the frame rods to be shortened to reduce the overall length, the height frame rods to be deflected to reduce the overall height, the width frame rods to be shortened to reduce the overall width, and the height frame rods to be able to press the casters down to contact the ground for rolling transport when deflected. This solves the problem that existing metal wardrobe frames need to be completely disassembled before transport.

[0005] To achieve the above objectives, this application adopts the following technical solution: a lightweight metal wardrobe frame that is easy to move, comprising four corner positioning posts and multiple length frame rods, width frame rods, and height frame rods that make up the frame; the length frame rods, width frame rods, and height frame rods have the same structure; the length frame rod includes a storage tube and an extension tube, the end of the extension tube near the storage tube is provided with an external thread section, the end of the storage tube near the extension tube is provided with an internal thread section, and the external thread section and the internal thread section are threadedly connected; a positioning crossbar is provided between the two positioning posts in the width direction, the positioning crossbar is provided with two symmetrical sleeves, the top of both sides of the sleeves is provided with two symmetrical hinge plates, and the bottom of the height frame rod is hinged to the hinge plates; the two ends of the width frame rod are provided with symmetrical clamps that connect to the two height frame rods.

[0006] Preferably, the inner diameter of the receiving tube is greater than the outer diameter of the external thread section, and the inner diameter of the internal thread section is greater than the outer diameter of the extension tube.

[0007] Preferably, the length frame rod is horizontally positioned between two positioning posts in the length direction, and a T-shaped positioning rod is movably provided at the end of the extension tube cavity on the length frame rod away from the receiving tube, which is connected to the nearby positioning post.

[0008] Preferably, the inner cavity of the end of the extension tube away from the receiving tube has a T-shaped cross-section, and the axial cross-section of the T-shaped positioning rod has a T-shaped cross-section.

[0009] Preferably, the connection method between the clamp and the height frame rod is the same as the connection method between the T-shaped positioning rod and the length frame rod.

[0010] Preferably, a hanging rod is provided between two opposite width frame rods in the length direction, and symmetrical sleeves are provided at both ends of the hanging rod. The sleeves are hollow semi-circular and are fastened to the width frame rods.

[0011] Preferably, two symmetrical mounting plates are provided on both sides of the length frame rod near the positioning column, and a rotating rod is provided on the side of the mounting plate away from the length frame rod, and a caster wheel is provided at the bottom of the rotating rod.

[0012] Preferably, a spring is sleeved on the outer side of the rotating rod, the top end of the spring is connected to the top of the rotating rod, and the bottom end of the spring is connected to the top of the mounting plate.

[0013] Preferably, a magnet is provided below the top of the rotating rod, and the magnet is located at the top of the mounting plate.

[0014] The lightweight metal wardrobe frame provided in this application is designed to be easy to move. By setting the frame rods as retractable storage tubes and extension tubes, the metal wardrobe frame can be reduced in height, width and length when it is moved. This reduces the overall frame volume and eliminates the need to completely disassemble the metal frame before moving it, thus improving the ease of handling.

[0015] Meanwhile, after reducing the volume, the frame rods in the height direction can be rotated around the hinge point of the hinge plate, causing the frame rods in the height direction to tilt to the bottom of the frame, further reducing the height of the metal frame. At this time, the tilted frame rods will press against the top of the rotating rod, causing the rotating rod to move downwards and drive the casters below to extend and contact the ground. This allows the entire metal frame to be dragged directly during transportation, with the casters on the ground rolling for transport, further improving the convenience of transportation.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0020] Example 1 Please see Figures 1 to 3 The lightweight metal wardrobe frame is easy to move and includes four corner positioning posts 1 and multiple length frame rods, width frame rods and height frame rods that make up the frame. These structures form the three-dimensional structure of the metal wardrobe frame.

[0021] The length frame bar, width frame bar, and height frame bar have the same structure.

[0022] See Figure 1 , Figures 3 to 5The length frame rod includes a receiving tube 3 and an extension tube 4. The end of the extension tube 4 near the receiving tube 3 is provided with an external thread section 41, and the end of the receiving tube 3 near the extension tube 4 is provided with an internal thread section 31. The external thread section 41 and the internal thread section 31 are threadedly connected, so that the extension tube 4 can be movably sleeved in the receiving tube 3 through the threaded connection between the external thread section 41 and the internal thread section 31. This allows the extension tube 4 to adjust its length protruding from the receiving tube 3 by rotation, thereby adjusting the length of the length frame rod, the width frame rod, and the height frame rod.

[0023] See Figures 4 to 5 The inner diameter of the receiving tube 3 is greater than the outer diameter of the external thread section 41, and the inner diameter of the internal thread section 31 is greater than the outer diameter of the extension tube 4, so that the internal thread section 31 will not hinder the free movement of the extension tube 4, and the external thread section 41 can also freely enter the inner cavity of the receiving tube 3.

[0024] See Figures 1 to 3 The length frame rod is horizontally set between two positioning posts 1 in the length direction, so that the movers can rotate the extension tube 4 on the length frame rod to move the extension tube 4 inward to the storage tube 3, shortening the length of the entire length frame rod, or move the extension tube 4 outward to the storage tube 3, extending the length of the entire length frame rod. Thus, the length of the metal wardrobe frame can be shortened during handling, making it easier to move, and the length of the entire length frame rod can be extended back after handling. A positioning crossbar 2 is fixedly connected between the two positioning posts 1 in the width direction.

[0025] See Figure 4 A T-shaped positioning rod 42 is movably sleeved at the end of the extension tube 4 on the length frame rod away from the receiving tube 3. The end of the T-shaped positioning rod 42 away from the extension tube 4 is fixedly connected to the nearby positioning post 1 by bolts.

[0026] See Figure 4 The inner cavity of the extension tube 4 at the end away from the receiving tube 3 has a T-shaped cross section, and the axial cross section of the T-shaped positioning rod 42 has a T-shaped cross section, which allows the extension tube 4 at this point to rotate, and is restricted by the T-shaped positioning rod 42, so that it will not detach from the nearby positioning post 1.

[0027] See Figures 1 to 3Two symmetrical sleeves 6 are movably sleeved on the positioning crossbar 2. Two symmetrical hinge plates 61 are welded to the top of both sides of the sleeves 6. The height frame rod is vertically set above the positioning crossbar 2. The bottom of the height frame rod is hinged to the hinge plate 61, so that the sleeves 6 can drive the height frame rod to move in the width direction, thereby controlling the width between the two height frame rods on the same positioning crossbar 2. It also allows the height frame rod to deflect with the hinge point with the hinge plate 61 as the base point, so that the height frame rod can deflect and shrink in width, further reducing the three-dimensional volume of the entire metal wardrobe frame.

[0028] See Figure 1 , Figure 5 Multiple horizontally arranged width frame rods are set between two height frame rods on the same positioning crossbar 2. The two ends of the width frame rods are movably connected with symmetrical clamps 5. Two clamps 5 are fixedly sleeved on two height frame rods respectively. The connection method between the clamps 5 and the height frame rods is the same as the connection method between the T-shaped positioning rod 42 and the length frame rods. This allows the extension tube 4 on the width frame rod to be length-adjusted within the storage tube 3, thereby adjusting the length of the width frame rod to adjust the width between the two height frame rods on a single positioning crossbar 2. When the width frame rod needs to be adjusted in height, the bolts on the clamps 5 can be loosened, thereby changing the clamps 5 from a fixed sleeve to a movable sleeve. At this time, the width frame rod can be adjusted in height on the height frame rods.

[0029] See Figure 1 , Figure 6 A hanging rod 10 is installed between two opposite width frame rods in the length direction. The two ends of the hanging rod 10 are fixedly connected to symmetrical sleeves 11. The sleeves 11 are hollow semi-circular. The sleeves 11 on both sides are respectively locked onto the two width frame rods on the horizontal sides, so that the two ends of the hanging rod 10 are connected to the width frame rods on both sides through the sleeves 11 on both sides. This prevents the width frame rods on both sides from moving away from the hanging rod 10, so that the height frame rod cannot deflect. When transporting, after the hanging rod 10 is quickly removed, the width frame rods on both sides are no longer restricted. At this time, the height frame rod can deflect.

[0030] Example 2 Please see Figures 1 to 4 , Figure 7 Based on Embodiment 1, two symmetrical mounting plates 7 are welded to the two sides of the length frame rod near the positioning column 1. A rotating rod 81 is movably sleeved on the side of the mounting plate 7 away from the length frame rod. A caster wheel 8 is movably connected to the bottom of the rotating rod 81, so that when the caster wheel 8 is on the ground, the metal wardrobe frame can push and drive the caster wheel 8 to roll, thus completing the rapid transportation.

[0031] See Figure 7The axial cross-section of the rotating rod 81 is T-shaped. A spring 9 is sleeved on the outside of the rotating rod 81. The top end of the spring 9 is fixedly connected to the top of the rotating rod 81, and the bottom end of the spring 9 is fixedly connected to the top end of the mounting plate 7. Under normal conditions, the caster wheel 8 is raised upwards away from the ground, so that the spring 9 can drive the rotating rod 81 to rise, thereby driving the caster wheel 8 to rise and leave the ground. Thus, under normal conditions, the caster wheel 8 will not contact the ground and roll. At this time, the bottom end of the positioning column 1 contacts the ground, ensuring the stability of the metal wardrobe frame.

[0032] After reducing the volume of the metal wardrobe frame, the height frame rod can be rotated with the hinge point of the hinge plate 61 as the base point, causing the height frame rod to tilt to the bottom of the frame, further reducing the height of the metal frame. At this time, the length of the width frame rod is adjusted so that the tilted height frame rod can be pressed against the top of the rotating rod 81, causing the rotating rod 81 to move downward, driving the universal wheel 8 below to extend out (at this time, the spring 9 is compressed) and contact the ground. This allows the entire metal frame to be dragged directly during transportation, with the universal wheel 8 rolling and transporting it, further improving the convenience of transportation.

[0033] It should be noted that during the handling process, when facing uneven road surfaces, the caster wheel 8 has a corresponding degree of freedom in the height direction, which allows it to move up and down under the action of the spring force of the spring 9 and the uneven ground. This allows the caster wheel 8 to adapt to more handling road environments and further improve the convenience of handling. During the upward movement of the caster wheel 8, it will push the height frame rod that is in contact with it, causing the height frame rod to suddenly deflect upward and temporarily detach from the rotating rod 81, and then fall down again to hit the rotating rod 81, so that the caster wheel 8 can still move downward and contact the ground.

[0034] See Figure 1 , Figure 3 The mounting plates 7 on the two length frame rods are opposite each other, so that the height frame rod can press on the rotating rod 81 when it deflects. When the caster 8 contacts the ground, the distance between the bottom of the positioning post 1 and the ground is greater than the diameter of the caster 8, so that the metal wardrobe frame can adapt to the ground with a greater height difference during transportation.

[0035] Example 3 Please see Figures 1 to 4 , Figure 7Based on Embodiment 2, a magnet 71 is provided below the T-shaped top of the rotating rod 81. The magnet 71 is fixedly connected to the top of the mounting plate 7. The rotating rod 81 is made of a metal that can be attracted by a magnet. When the height frame rod is pressed on the rotating rod 81, this part of the height frame rod and the top of the rotating rod 81 can be close to the magnet 71, so that the magnet 71 attracts them, increasing the downward force of the caster wheel 8. Thus, when the caster wheel 8 lifts up on uneven ground, the attraction of the magnet 71 can offset part of the upward force of the rotating rod 81, thereby further reducing the lifting height of the caster wheel 8. This avoids the problem of the caster wheel 8 lifting too high, causing the bottom of the positioning post 1 to contact the ground and be blocked by the ground, resulting in the stopping of the transport. At the same time, it also reduces the upward deflection of the height frame rod, improving safety.
