However, when using the merchandise storage rack, multiple workers are needed to lift and move it, as the current device lacks a movable structure, greatly increasing the workload of the workers and causing inconvenience.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an adjustable merchandise storage rack, including a frame, with a support frame installed at the bottom of the frame; a lifting mechanism is provided inside the bottom of the frame, and a limit component is provided on the inner side of the frame;

[0008] The lifting mechanism includes fixed boxes, which are symmetrically installed inside the bottom of the frame. A drive rod is rotatably connected between the fixed boxes. Threaded teeth are symmetrically welded to the outer sides of both ends of the drive rod, and trapezoidal blocks are threaded to the outer sides of the threaded teeth. A support rod is slidably connected inside the bottom of the fixed boxes. A wheel is installed at the top of the support rod, and a first retraction spring is sleeved on the outer side of the top of the support rod. A wheel is installed at the bottom of the support rod, and a handle is installed at one end of the drive rod.

[0009] Preferably, a support plate is installed on one side of the bottom end of the frame, and a slide rod is slidably connected inside the support plate. A second retraction spring is sleeved on the outside of the slide rod. A connecting plate is installed at the bottom end of the slide rod, and a protrusion is installed at the bottom end of the connecting plate. Circular grooves are opened on the outside of the handle, and the protrusions are inserted into the circular grooves.

[0010] Preferably, the limiting component includes a carrying plate, and the carrying plates are all disposed inside the support frame. The inner side of the support frame is symmetrically provided with sliding grooves. The two ends of the carrying plate are symmetrically installed with strips. A limiting box is installed between the carrying plate and the strips. A pull rod is slidably connected inside one end of the limiting box. A semi-circular plate is installed at one end of the pull rod. Limit frames are symmetrically installed on both sides of the limiting box. A moving rod is symmetrically slidably connected between the limiting box and the limiting frame. A moving plate is installed at one end of the moving rod. An insert is installed on one side of the moving plate. The insert is inserted into the inner side of the sliding groove. A third retraction spring is sleeved on the outer side of the pull rod.

[0013] Preferably, the carrier plate has symmetrical grooves on one side.

[0014] Preferably, the strip is slidably connected inside the groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: The adjustable merchandise storage rack is characterized by the following: the rotation of the drive rod drives the rotation of the threaded teeth, which in turn causes the trapezoidal block to slide inside the fixed box. At this time, the rotating wheel rolls on the slope of the trapezoidal block surface, and the support rod gradually moves downward. At this time, the first contraction spring contracts, which allows the two sets of wheels to lift the rack. The staff can then push the rack to move and transfer the device, thereby achieving the effect of quickly adjusting the lifting and lowering of the wheels. This facilitates the staff to move and transport the rack quickly, greatly improving the flexibility of the device and reducing the burden on the staff when transporting the rack. When the staff pushes the pull rod to slide inside the limit box, the semi-circular plate slides inside the limit box, which in turn squeezes the two sets of moving rods. The movement of the moving rods causes the moving plate to slide inside the limit frame, which in turn allows multiple sets of inserts to be inserted into the inner side of the slide groove. This enables the quick installation and removal of the display plate, allowing the staff to quickly adjust the assembly of the display plate according to the specifications of the merchandise, greatly improving the flexibility of the device.

[0016] 1. By rotating the handle lever to drive the drive rod, the rotation of the drive rod causes the threaded teeth to rotate, which in turn causes the trapezoidal block to slide inside the fixed box. The movement of the trapezoidal block compresses the rotating wheel, causing the wheel to roll on the slope of the trapezoidal block's surface. Simultaneously, the support rod gradually moves downwards, at which point the first compression spring contracts, allowing the two sets of wheels to lift the frame. The operator then pushes the frame to move and transfer the device, enabling rapid adjustment of the wheel height. This facilitates quick movement and transport of the frame, significantly improving the efficiency of the device's use. The flexibility reduces the burden on workers when moving the frame and brings convenience to workers during use. When workers pull the slide rod to slide inside the support plate, the connecting plate compresses the second contraction spring. At this time, the second contraction spring contracts. By releasing the slide rod and the restoring property of the second contraction spring, the protrusion can be quickly inserted into the circular groove, thereby achieving the effect of quickly fixing the limit handle rod. This can limit the adjusted drive rod and prevent the wheel and trapezoidal block from misaligning when the frame moves on bumpy roads, thus preventing the wheel from accidentally retracting.

[0017] 2. Workers place multiple sets of trays inside the frame. The trays insert into the sliding grooves, allowing workers to adjust the distance between them according to the product specifications. Then, workers push the pull rods to slide within the limiting box, causing a semi-circular plate to slide inside. At this point, the third retraction spring extends and resets, pressing the semi-circular plate against two sets of moving rods. The movement of the moving rods causes the moving plate to slide within the limiting frame. The fourth retraction spring extends, allowing multiple sets of inserts to engage with the inner side of the sliding groove. The tension generated by the third and fourth retraction springs presses against the semi-circular plate, enabling rapid installation and removal of the trays. This allows workers to quickly adjust the tray assembly according to product specifications, greatly improving the flexibility of the device, meeting the needs of various product sizes, saving space, and providing convenience for workers.

[0028] A support plate 210 is installed on one side of the bottom of the frame 1, and a slide rod 211 is slidably connected inside the support plate 210. A second retraction spring 212 is sleeved on the outside of the slide rod 211. A connecting plate 213 is installed at the bottom of the slide rod 211, and a protrusion 214 is installed at the bottom of the connecting plate 213.

The device is fixedly connected to the inner side of the bottom end of the frame 1. Through the reset property of the second retraction spring 212, the protrusion 214 can be quickly inserted into the circular groove 215, thereby achieving the effect of quickly fixing the limit handle 209. This can limit the adjusted drive rod 202, preventing the wheel 206 and trapezoidal block 204 from misaligning when the frame 1 moves on bumpy roads, thus preventing the wheel 208 from accidentally retracting. This greatly improves the stability of the device during use and brings practicality to the staff.

[0029] The limiting component 3 includes a carrying plate 301, which is disposed inside the support frame 101. The support frame 101 has symmetrically formed sliding grooves 302 on its inner side. Strips 303 are symmetrically installed at both ends of the carrying plate 301, and are slidably connected within the sliding grooves 302. A limiting box 304 is installed between the carrying plate 301 and the strips 303, and a pull rod 305 is slidably connected to one end of the limiting box 304. A semicircular plate 306 is installed at one end of the 5, and limit frames 307 are symmetrically installed on both sides of the limit box 304. A moving rod 308 is symmetrically slidably connected between the limit box 304 and the limit frame 307. A moving plate 309 is installed at one end of the moving rod 308, and a plug 310 is installed on one side of the moving plate 309. The plug 310 is inserted into the inner side of the slide groove 302. A third retraction spring 311 is sleeved on the outer side of the pull rod 305. A fourth retraction spring 312 is symmetrically installed between one side of the 09 and the limiting box 304, and sliders 313 are symmetrically installed on both sides of the semicircular plate 306.

At this time, the tension generated by the third retraction spring 311 and the pulling force generated by the fourth retraction spring 312 compress the semicircular plate 306, thereby achieving the effect of quickly installing and disassembling the carrier plate 301. In addition, the staff can quickly adjust the assembly of the carrier plate 301 according to the specifications of the goods, greatly improving the flexibility of the device during use, meeting the needs of placing various specifications of goods, saving space, and bringing convenience to the staff during use. A groove 315 is symmetrically opened on one side of the carrier plate 301. The design of the groove 315 makes it easy for the staff to operate the pull rod 305.

[0030] Working principle: Before using this adjustable merchandise storage rack, it is necessary to check the overall condition of the device to ensure it can function properly. Figure 1 - Figure 6As shown, when the operator rotates the two sets of handle levers 209, the handle levers 209 drive the drive lever 202 to rotate. The rotation of the drive lever 202 drives the threaded gear 203 to rotate, and the rotation of the threaded gear 203 causes the trapezoidal block 204 to slide inside the fixed box 201. The movement of the trapezoidal block 204 compresses the rotating wheel 206, causing the rotating wheel 206 to roll on the slope of the trapezoidal block 204. At this time, the support rod 205 gradually moves downward, and the first contraction spring 207 contracts, allowing the two sets of wheels 208 to lift the frame 1. The operator then pushes the frame 1 to move and transfer the device. By rotating the drive lever 202 in the opposite direction, the trapezoidal block 204 returns to its original position, and the first contraction spring 207 extends, causing the wheels 208 to quickly retract into the support frame 101. This allows for rapid adjustment of the lifting and lowering of the wheels 208, thus facilitating convenient... The device allows for rapid movement and handling of the frame 1 by staff, greatly improving the flexibility of its use and reducing the burden on staff during transport. This enhances convenience for staff during operation. When staff pull the slide bar 211, it slides within the support plate 210. At this time, the connecting plate 213 compresses the second contraction spring 212, causing it to contract. By releasing the slide bar 211 and utilizing the restoring property of the second contraction spring 212, the protrusion 214 can quickly engage with the circular groove 215, thus quickly fixing the limit handle 209. This limits the adjusted drive rod 202, preventing misalignment between the wheel 206 and the trapezoidal block 204 when the frame 1 moves on bumpy roads, and preventing the wheel 208 from accidentally retracting. This significantly improves the stability of the device during use and enhances its practicality for staff.

[0031] Workers place multiple sets of trays 301 inside the frame 1. The strips 303 are then inserted into the slide grooves 302. Workers can adjust the distance between the trays 301 according to the specifications of the goods. Workers then push the pull rod 305 to slide inside the limiting box 304. At this time, the semi-circular plate 306 slides inside the limiting box 304. The third contraction spring 311 extends and resets, causing the semi-circular plate 306 to press against the two sets of moving rods 308. The movement of the moving rods 308 causes the moving plate 309 to slide inside the limiting frame 307. At this time, the fourth contraction spring 312 extends. This allows multiple sets of insert blocks 310 to be inserted into the inner side of the slide groove 302. At this time, the tension generated by the third contraction spring 311 and the pulling force generated by the fourth contraction spring 312 compress the semi-circular plate 306, thereby achieving the effect of quickly installing and disassembling the carrier plate 301. As a result, the staff can quickly adjust the assembly of the carrier plate 301 according to the specifications of the goods, greatly improving the flexibility of the device during use, meeting the needs of placing goods of various specifications, saving space, and bringing convenience to the staff during use. The design of the groove 315 makes it easy for the staff to operate the pull rod 305.
