Description

Technical Field

[0001] The invention relates to the technical field of single-sided shelves, and in particular to a single-sided load-bearing anti-dumping shelf. Background Art

[0002] Single-sided load-bearing racks are a type of storage equipment widely used in warehousing and logistics. They are designed for storing various types of goods. Their design and structure enable them to be loaded on one side, thereby maximizing the use of warehouse space and improving storage efficiency. These racks are usually made of steel and are characterized by high strength and durability. They can be customized according to specific needs and are suitable for a variety of goods of different weights and sizes.

[0003] When the current single-sided load-bearing shelves are actually used and bear weight, when facing some heavier goods, such as steel pipes and steel materials, the force-bearing position of the shelf will tilt forward. This situation will seriously affect the stability of the shelf. When the shelf is subjected to impact force, it is very easy for the shelf to tip over, resulting in property loss and safety hazards. In addition, this type of shelf cannot achieve the desired stability while also being movable, resulting in poor flexibility of the shelf, which is extremely inconvenient when transportation or unloading is required.

[0012] Furthermore, another set of winding wheels is fixed to the transmission teeth through a shaft rod, and the top of one side of the transmission teeth engages with the force-bearing teeth, and the force-bearing teeth are limited to rotate above the inner bracket.

[0013] Furthermore, the inner bracket has a receiving groove near the stressed teeth, a threaded telescopic rod is slidably connected in the receiving groove, the thread of the threaded telescopic rod passes through the stressed teeth, and the top of the threaded telescopic rod is fixed to the outer bracket.

[0014] Furthermore, the pressure mechanism includes auxiliary teeth and a locking screw, the locking screw thread passes through the auxiliary teeth, the bottom of one side of the auxiliary teeth is meshed with main teeth, and one side of the main teeth is fixed to the rocker.

[0015] Furthermore, the two ends of the locking screw are respectively fixed with limit sliders, and both sets of limit sliders slide in the slide grooves on the sides of the inner bracket, and a pressure shaft is fixedly arranged on one side of a single set of limit sliders.

[0016] Furthermore, a force axis is provided on one side of the shelf plate close to the inner bracket, the force axis is located at the top of one end of the supporting tilt rod, the pressure axis is located at the top of the other end of the supporting tilt rod, and the rotation center of the supporting tilt rod is located close to the force axis.

[0019] The beneficial effects of the present invention are:

[0020] The present invention utilizes the movable connection effect between the shelf plate and the connecting rod, so that when the shelf plate is actually carrying loads, the effect of gravity will cause the shelf plate and the connecting rod to flip at a small angle, so that the entire shelf plate can be regarded as hanging on the connecting rod. This situation can effectively calibrate the gravity direction of the shelf plate and alleviate the overall stress condition of the device, preventing the center of gravity of the goods on the transmission shelf from tilting forward or backward, thereby effectively improving the overall stability of the device.

[0021] The present invention arranges a spring damping rod at the bottom of the shelf board so that the spring damping rod can provide a lateral limiting pulling force or pushing force at the bottom of the shelf board. When the shelf board is subjected to an impact force, the elastic action of the spring damping rod can effectively absorb and buffer the impact force, thereby reducing the shaking amplitude of the shelf board, further improving the stability of the shelf board, and preventing the shelf board from tipping over.

[0022] The present invention provides an adjustment mechanism and a moving mechanism. After shaking the hand wheel, on the one hand, the inner bracket can be driven to move upward on one side of the outer bracket as a whole, so that the roller contacts the ground, thereby achieving the effect of flexible movement of the device as a whole. On the other hand, the rotation of the transmission shaft can also drive the bottom of the spring damping rod to move horizontally on the inner bracket through the screw rod, thereby adapting the connection position between the top of the spring damping rod and the shelf board, so that no matter how it is adjusted, the bottom of the shelf board can always be subjected to the lateral limiting tension of the spring damping rod, thereby ensuring that the anti-dumping effect always exists.

[0023] The present invention provides a support tilting rod, one side of which is subjected to the downward pressure of the limit slider, so that the other side thereof is lifted upward, thereby pushing the middle position of the shelf board upward through the force-bearing axis, which can effectively share the gravity pressure of the shelf board, thereby protecting the connection effect between the shelf board and the connecting rod, and preventing the connection position of the shelf board and the connecting rod from being deformed by pressure after long-term use; BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0037] refer to Figure 1-Figure 8 , including two groups of outer brackets 1 and inner brackets 4, the inner brackets 4 move up and down between the outer brackets 1 and the shelf board 3 through the adjustment mechanism 5 inside thereof, the inner brackets 4 are transmission-connected with the outer brackets 1 through the adjustment mechanism 5, the tops of the two groups of outer brackets 1 are respectively fixed on the left and right sides of the connecting rod 2, the surfaces on both sides of the connecting rod 2 are movably connected to the shelf board 3 through the load-bearing shaft, and a shelf is arranged between the two groups of shelf boards 3;

[0038] The lower part of the shelf plate 3 is rotatably connected to the output end of the upper part of the spring damping rod 6 through an axle pin, and the lower part of the spring damping rod 6 moves laterally on the surface of the inner bracket 4 through an adjustment mechanism 5;

[0039] The outer bracket 1 is provided with two sets of rollers 91 for transverse sliding, and the rollers 91 are rotatably connected to the inner bracket 4 via a swing rod 95;

[0040] A support lever 7 is provided on one side of the inner bracket 4 close to the shelf board 3 through rotation of an axle rod. One side of the support lever 7 is movably connected to the shelf board 3 . The support lever 7 is limited on the surface of the inner bracket 4 by a pressure mechanism 8 .

[0041] In this embodiment, firstly, the single-sided support shelf is composed of two groups of outer brackets 1, a single group of connecting rods 2, two groups of shelf boards 3, two groups of inner brackets 4 and the cargo stacking racks between the shelf boards 3. Different from the traditional single-sided support shelf, the shelf boards 3 are movably connected to the connecting rods 2 through load-bearing bearings, so that the two groups of shelf boards 3 can be regarded as hoisted on the connecting rods 2, and some cargo such as steel pipes are stacked on the shelf boards 3. Under the action of gravity, the shelf boards 3 will tilt at a certain angle, thereby adapting to the direction of gravity, making the overall hoisting of the cargo more stable;

[0042] Furthermore, since the shelf board 3 and the connecting rod 2 are in an active state, a spring damping rod 6 is provided between the bottom of the shelf board 3 and the inner bracket 4 through an adjustment mechanism 5. Under normal circumstances, the telescopic end of the spring damping rod 6 is movably connected to the bottom of the shelf board 3. In this way, when the shelf board 3 is subjected to external impact or force shaking, the shaking amplitude will be elastically damped by the bottom spring damping rod 6, thereby reducing the shaking amplitude of the shelf board 3 and absorbing energy of the shaking, thereby further improving the stability of the shelf board 3, making it difficult for the shelf board 3 as a whole to tip over;

[0043] During normal use, the bottom surface of the inner bracket 4 is in contact with the ground, and the bottom of the roller 91 is also in contact with the ground, so that the inner bracket 4 is connected to the outer bracket 1 through the adjustment mechanism 5, and the shelf board 3 provides the basic support effect of a traditional single-sided support shelf. When the adjustment mechanism 5 drives the inner bracket 4 and the outer bracket 1 to move relative to each other, the inner bracket 4 is forced to move upward, so that the bottom surface of the inner bracket 4 is separated from the ground, so that the overall movement is driven by the roller 91, and the device has strong flexibility.

[0044] Since the shelf board 3 is suspended on the surface of the connecting rod 2, after long-term use, the contact position between the connecting rod 2 and the shelf board 3 may be deformed due to pressure, which may lead to damage to the device. Therefore, in actual use, the supporting tilting rod 7 is rotatably set at a side position of the inner bracket 4 close to the shelf board 3, the top of one end of the supporting tilting rod 7 is in contact with the shelf board 3, and the top of the other side is in contact with the pressure-applying mechanism 8, and the rotation center of the supporting tilting rod 7 is close to the contact position with the shelf board 3. In this way, when the supporting tilting rod 7 is subjected to force on the side close to the pressure-applying mechanism 8, the pressure causes the supporting tilting rod 7 to support the shelf board 3 like a lever, thereby sharing the force of the connecting rod 2, effectively protecting the use of the device, and preventing pressure deformation and damage.

[0045] refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 The adjusting mechanism 5 includes a transmission shaft 52 and a revolving assembly 56. One end of the transmission shaft 52 is fixedly connected to the handwheel 51. The surface of the transmission shaft 52 near the handwheel 51 drives the screw 54 to rotate at the bottom of the inner bracket 4 through the belt transmission assembly 53. The surface of the screw 54 is threadedly connected to the transmission block 55. The transmission block 55 is limited and slides at the bottom of the inner bracket 4. The transmission block 55 is rotatably connected to the bottom of the spring damping rod 6 through the side plate.

[0046] The cam 52 is then rotated to move the spring cam 60 from the bottom to the bottom of the rack 40. The cam 52 is then rotated to move the spring cam 60 from the bottom to the top of the rack 40. The cam 52 is then rotated to move the spring cam 60 from the bottom to the top of the rack 40. The cam 52 is then rotated to move the spring cam 60 from the bottom to the top of the rack 40.

[0047] refer to Figure 3 , Figure 4 , Figure 5 and Figure 6The winding assembly 56 includes two groups of winding wheels 561 and transmission teeth 563. The surfaces of the two groups of winding wheels 561 are wound with winding cables 562. The two groups of winding wheels 561 transmit power to each other through the winding cables 562. A single group of winding wheels 561 is fixed to one end of the transmission shaft 52, and the transmission shaft 52 is rotatably arranged inside the inner bracket 4. The other group of winding wheels 561 is fixed to the transmission teeth 563 through a shaft rod. The top of one side of the transmission teeth 563 engages with the force-bearing teeth 564, and the force-bearing teeth 564 are limited and rotated above the inner bracket 4. The inner bracket 4 is provided with a receiving groove 565 near the position of the force-bearing teeth 564. The receiving groove 565 is slidably connected with a threaded telescopic rod 566. The threaded telescopic rod 566 passes through the force-bearing teeth 564, and the top of the threaded telescopic rod 566 is fixed to the outer bracket 1.

[0048] In the present embodiment, the rotation of the transmission shaft 52 can directly drive the winding wheel 561 to rotate. After a single set of winding wheels 561 rotates, the cable 562 wound around its surface will be wound up or loosened, pulling the other set of winding wheels 561 on the top of the inner bracket 4 to rotate. At this time, the winding wheel 561 will directly drive the transmission gear 563 to rotate through the shaft rod, and the transmission gear 563 will mesh with the force-bearing gear 564, and the force-bearing gear 564 will be threadedly connected with the threaded telescopic rod 566. In this way, when the force-bearing gear 564 is limited to rotate above the inner bracket 4, the threaded telescopic rod 566 will telescope and slide up and down in the storage groove 565, thereby driving the inner bracket 4 to rise.

[0049] refer to Figure 5 The pressure mechanism 8 includes a secondary tooth 83 and a locking screw 84. The locking screw 84 is threaded through the secondary tooth 83. The bottom of one side of the secondary tooth 83 is meshed with a main tooth 82. One side of the main tooth 82 is fixed to the rocker 81. Limiting sliders 85 are fixed at both ends of the locking screw 84. Both sets of limiting sliders 85 are limited to slide in the slide groove on the side of the inner bracket 4. A pressure shaft 86 is fixed on one side of the single set of limiting sliders 85. A force shaft 87 is set on the side of the shelf board 3 close to the inner bracket 4. The force shaft 87 is located at the top of one end of the support tilting rod 7. The pressure shaft 86 is located at the top of the other end of the support tilting rod 7. The rotation center of the support tilting rod 7 is located near the force shaft 87.

[0050] The locking screw 84 is also limited to slide on one side of the inner bracket 4 by the limit sliders 85 at both ends, so that the locking screw 84 will also move up and down, thereby driving the pressure shaft 86 on one side of the limit slider 85 to move up and down. When the pressure shaft 86 moves downward, it will squeeze the top of one side of the supporting tilt rod 7. After being subjected to force, the other side of the supporting tilt rod 7 will lift the force shaft 87 on the side of the shelf board 3. On the contrary, the supporting tilt rod 7 releases the resistance to the shelf board 3. This effect can effectively share the force of the connecting rod 2 through the resistance of the supporting tilt rod 7, and effectively and evenly share the pressure of the shelf board 3 to the outer bracket 1 and the inner bracket 4, thereby further improving the structural stability.

[0051] refer to Figure 7 and Figure 8 The moving assembly 9 includes two groups of rollers 91 and a support seat 93. The axis of the roller 91 is rotatably connected to the bottom of the support seat 93 through a wheel shaft 92. The support seat 93 is slidably arranged in a transverse slide groove 94 provided at the bottom of the outer bracket 1, and a load-bearing bearing is movably arranged between the top of the support seat 93 and the inner bracket 4. The side of the wheel shaft 92 away from the support seat 93 is movably connected to a swing rod 95. The side of the swing rod 95 away from the wheel shaft 92 is movably connected to a rotating shaft 96. The rotating shaft 96 is fixed to the side of the bottom of the inner bracket 4.

[0052] In the present embodiment, during the rising process of the inner bracket 4, its bottom surface is separated from the ground. At this time, the rising of the inner bracket 4 will drive the rotating shaft 96 to rise, and the swing rod 95 movably connected to the rotating shaft 96 will push the axle 92 and the roller 91 to move to one side, so that the axle 92 drives the support seat 93 to slide in the horizontal slide groove 94 under the outer bracket 1, so that the roller 91 is first unfolded, and then the rotation effect drives the rollers 91 to align with each other. At this time, the outer bracket 1 or the shelf board 3 as a whole can be pushed normally, driving the device to move, effectively improving the flexibility of the shelf.

[0053] Working principle: First, by turning the hand wheel 51, the transmission shaft 52 is driven to rotate in the inner bracket 4. On the one hand, the transmission shaft 52 is connected with the screw rod 54 through the belt transmission assembly 53, so that the transmission block 55 moves on the surface of the screw rod 54, thereby driving the spring damping rod 6 to move horizontally below, and changing the height of the connection position between the spring damping rod 6 and the shelf board 3. At the same time, the two sets of winding wheels 561 are connected by the movable connection effect of the cable 562, so that the transmission shaft 52 can directly drive the winding wheel 561 to rotate. In this way, after the transmission meshing teeth 563 are driven to rotate by the winding wheel 561, the meshing effect between the meshing teeth 563 and the force-bearing meshing teeth 564 causes the threaded telescopic rod 566 to move up and down in the storage groove 565, thereby realizing the rise or fall of the inner bracket 4.

[0054] The inner bracket 4 will drive the rotating shaft 96 to rise synchronously during the rising process, and the swing rod 95 will push the wheel shaft 92 and the roller 91 to move to one side, and then the roller 91 will be stabilized under the sliding effect of the support seat 93 and the horizontal slide groove 94 at the bottom of the outer bracket 1, and then the roller 91 will contact the ground, and the shelf can be pushed flexibly at this time;

[0055] After the inner bracket 4 descends, its bottom surface will contact the ground, thereby cooperating with the outer bracket 1 to achieve a better supporting effect, thereby further improving stability;

[0056] After the installation is completed, the main gear 82 is driven to rotate by rotating the rocker 81. The meshing effect of the main gear 82 and the auxiliary gear 83 and the locking screw 84 sliding on the side of the inner bracket 4 through the limit slider 85 make the locking screw 84 move up and down. Here, it means that the locking screw 84 and the auxiliary gear 83 have a threaded transmission effect that drives the locking screw 84 to move. Then the pressure shaft 86 on one side of the limit slider 85 will press down the top of one side of the supporting tilt rod 7. The supporting tilt rod 7 rotates on the side of the inner bracket 4 close to the shelf board 3, so that the other side of the supporting tilt rod 7 will be lifted upward until it contacts the force-bearing shaft 87 on the side of the shelf board 3. At this time, part of the weight of the shelf board 3 will be lifted by the supporting tilt rod 7, thereby protecting the contact between the shelf board 3 and the connecting rod 2 and preventing damage to the device.
