Currently, the auxiliary facilities for product display mainly include display tables, display racks and display cabinets, among which display racks are the most widely used.

[0003] The patent document with application number 202111208469.0 discloses a glasses display stand, which includes a base, a shell and a plurality of pendants. The lower end of the shell is rotatably set on the base, and a connecting part is arranged on the side wall of the shell along the height direction. At least one connecting part is arranged at intervals around the circumference of the shell, and the pendant is arranged on the same side of the connecting part and is arranged at intervals along the height direction of the connecting part. An adjusting part for adjusting the inclination angle of the connecting part in the height direction is provided at the end of the connecting part. Support holes are provided on the side wall of the shell on both horizontal sides of each pendant, and the ear pads of the glasses are passed through and inserted into the support holes.

[0004] With respect to the above-mentioned related technologies, the inventor believes that the designed glasses display stand arranges multiple pairs of glasses in a vertical direction, which has a low space utilization rate in the vertical area, and the dust floating in the air can easily fall directly onto the glasses, affecting the display effect of the glasses. Summary of the invention

[0005] In order to reduce the negative impact of dust falling on exhibits and improve the space utilization rate in the vertical area where the display rack is located, the present application provides a highly reliable display rack, which adopts the following technical solution:

[0006] A high-reliability display rack comprises a rack body and a plurality of display units, wherein the plurality of display units are distributed in a vertical direction, and the display units comprise a bearing rack and a display frame;

[0007] The supporting frame is connected to the frame body;

[0008] The display frame is overlapped on the supporting frame, and the display frame is placed tilted downward.

[0009] By adopting the above technical solution, a highly reliable display rack is designed. The support frame is conveniently installed through the rack body, and the display frame is conveniently supported by the support frame. The space utilization rate in the vertical area can be improved by multiple display frames arranged in the vertical direction and inclined downward. In addition, since multiple display frames overlap in the vertical direction, the display frames in the upper space can provide dust shielding for the display frames in the lower space, thereby reducing the possibility of dust floating in the air directly falling on the exhibits, thereby improving the display effect of the exhibits.

[0010] Optionally, the supporting frame is fixedly connected to the frame body.

[0011] By adopting the above technical solution, the designed support frame fixedly connected to the frame body can provide structural stability of the support frame, thereby improving the position stability of the display frame and improving the safety of the exhibits placed in the display frame during display.

[0012] Optionally, it further includes a regulating unit, the regulating unit including a water tank and two sets of linkage parts;

[0013] The support frame is rotatably connected to the frame body, and a strip groove is provided on the support frame, and the water tank is installed on the frame body;

[0014] The linkage comprises a connecting pipe, a sliding plug, a mounting rod and a plurality of force transmission columns;

[0015] One end of the connecting pipe is connected to the water tank, and the other end is connected to the inner cavity of the hollow vertical rod of the frame body. The sliding plug is slidably connected to the inner cavity wall of the hollow vertical rod of the frame body, and the sliding plug is connected to the mounting rod;

[0016] A plurality of force transmission columns are distributed along the axial direction of the mounting rod, the force transmission columns are connected to the mounting rod, and the force transmission columns slide in the strip grooves.

[0017] By adopting the above technical solution, water is added to the water tank, and the water in the water tank applies force to the sliding plug through the connecting pipe. The sliding plug drives the mounting rod to rise along its own axis under the action of water pressure. While the mounting rod rises, it drives the force transmission column to slide along the opening direction of the strip groove, so that the supporting frame rotates around the rotation connection point between it and the frame body, thereby driving the display frame to complete the adjustment of the tilt angle until the angle of the display frame is appropriate, and then stop adding water to the water tank. When the customer takes out the exhibits from the display frame for viewing or purchasing, the total weight of the display frame and the exhibits inside it decreases, so the display frame tilts downward at an angle under the action of water pressure. The degree of tilting is reduced, and the water tank arranged at the lower end of the frame can also play a role in lowering the overall center of gravity of the high-reliability display frame, thereby reducing the possibility of the floor-standing frame tipping over. The designed adjustment unit provides a power source for the display frame to automatically adjust the tilt angle through the water tank, and can play a role of counterweight to reduce the possibility of the floor-standing frame tipping over. A water pressure-gravity dynamic feedback structure is formed through the connecting pipe, the sliding plug, the mounting rod and the force transmission column. The tilt angle of the display frame can be adjusted in real time according to the total weight of the exhibits in the display frame, so that the staff can find and replenish the goods in time, thereby improving the display effect of the display frame.

[0018] Optionally, the force transmission column includes an abutment section, an anti-tilt ring sheet and two support bars;

[0019] The mounting rod is hollow, and two opposite side walls of the mounting rod are connected with slide grooves, and the mounting rod is internally connected with multiple layers of support members along its own axial direction, and each layer of the support members includes two support sheets, and a gap is left between the two support sheets for the abutment section to pass through;

[0020] The anti-tilt ring piece is coaxially connected to the abutment section, and the anti-tilt ring piece moves axially along the mounting rod in the slide groove. The two support bars are evenly distributed along the circumference of the abutment section, and the support bars are connected to the abutment section.

[0021] By adopting the above technical solution, when it is necessary to adjust the inclination angle of a certain display frame separately, the abutting section is twisted, and the abutting section drives the anti-tilt ring piece and the two support bars to move with the abutting section itself as the axis, so that the two support bars are in a vertical state, and force is applied to the abutting section, and the abutting section drives the anti-tilt ring piece to move along the long side direction of the slide groove. At this time, the abutting section and the support bar can pass through the gap between the two support pieces to reach the adjacent upper or lower support member, and force is applied to the abutting section again to make the support bar abut against the support piece, thereby completing the individual inclination angle adjustment of the display frame; the designed force transmission column can realize the individual adjustment of the inclination angle of the display frame through the cooperation of the abutting section, the anti-tilt ring piece, the support bar and the support member.

[0022] Optionally, it further includes a control unit, the control unit including an adjustment cylinder, a force application rod, a rotating disk and a piston disk;

[0023] The regulating cylinder is provided with a plurality of water holes, the inner cavity of the regulating cylinder is connected with the inner cavity of the water tank through the water holes, the piston disc is slidably connected with the inner cavity of the regulating cylinder, and the bottom wall of the regulating cylinder is provided with an opening;

[0024] One side of the rotating disk is connected to the force applying rod, and the other side is in contact with the piston disk. The rotating disk and the piston disk can rotate relatively, and water outlet holes are provided on the rotating disk and the piston disk.

[0025] By adopting the above technical scheme, force is applied to the rotating disk through the force rod, and the rotating disk drives the piston disk to move, so that the piston rod moves along the axial direction of the adjusting cylinder, which will cause the volume of the accommodation space between the piston disk and the top wall of the adjusting cylinder to change. The water in the accommodation space and the water in the water tank flow through the water through the water hole, so that the water pressure generated by the water in the water tank changes. When the water in the water tank needs to be discharged, force is applied to the force rod, and the force rod rotates while driving the rotating disk to rotate until the water outlet hole on the rotating disk and the water outlet hole on the piston disk coincide with each other, and the water in the water tank and the accommodation space is discharged to the outside through the coincident water outlet hole; the designed control unit is convenient for controlling the movement of the rotating disk through the force rod, and convenient for driving the movement of the piston disk through the rotating disk, and cooperating with the piston disk to realize the discharge of water, and convenient for forming an adjustable accommodation space with the adjusting cylinder through the piston disk, thereby realizing the adjustment of the water pressure provided by the water tank.

A through hole is opened in the area of ​​the water suction pipe close to the bottom wall of the water tank, and a one-way valve is installed in the extended section of the water suction pipe passing through the water tank.

[0027] By adopting the above technical scheme, one end of the water suction pipe extending out of the water tank is extended into the water source, and the piston disk is driven by the force rod to move along the axial direction of the regulating cylinder toward the end away from the top wall of the regulating cylinder to generate a siphon force, so that the water in the water source is sucked into the water suction pipe through the one-way valve, and then the force rod is moved in the opposite direction, so that the water in the water suction pipe enters the water tank through the through hole, and the water filling action of the water tank is completed; when draining water, the piston disk is driven by the force rod to move along the axial direction of the regulating cylinder toward the end away from the top wall of the regulating cylinder to generate a siphon force, so that the water in the water tank enters the accommodating space through the through hole, and then force is applied to the force rod to connect the water outlet holes on the rotating disk and the piston disk, and the water in the accommodating space is discharged to the outside; the designed water suction pipe and one-way valve are convenient for cooperating with the control unit to realize the replenishment and discharge of water in the water tank.

[0028] Optionally, a shut-off valve is installed on the connecting pipe.

[0052] The implementation principle of a high-reliability display rack in Example 1 of the present application is as follows: a display frame 22 is sent from the rear end of the rack body 1 onto the carrier frame 21 until the display frame 22 abuts against the baffle bar. At this time, multiple display frames 22 are distributed along the height direction of the rack body 1, and the display frames 22 are tilted downward. While facilitating customers to observe and select exhibits, dust floating in the air can be blocked, thereby improving the space utilization rate in the vertical area where the floor-standing rack is located and reducing the negative impact of dust falling on the exhibits on the display effect.

[0053] Example 2

[0054] Reference Figure 3 , Figure 4 as well as Figure 5 The difference between Example 2 of the present application and the example is that: the support frame 21 is rotatably connected to the frame 1, and the rotation connection axis of the support frame 21 and the frame 1 is horizontally arranged, and a strip groove 211 is opened on the support frame 21. The high-reliability display rack also includes an adjustment unit and a control unit 5. The adjustment unit includes a water tank 3 and two sets of linkage parts 4. The water tank 3 is set on the frame 1, and the water tank 3 is located below the display frame 22.

[0055] Reference Figure 4 , Figure 5 as well as Figure 6 The linkage part 4 includes a connecting pipe 41, a sliding plug 42, a mounting rod 43 and a plurality of force transmission columns 44. One end of the connecting pipe 41 is connected to the bottom wall of the water tank 3, and the other end is connected to the hollow vertical rod. A shut-off valve 411 is connected to the flange on the connecting pipe 41. The sliding plug 42 is located in the hollow vertical rod, and the sliding plug 42 is slidably connected to the inner cavity wall of the hollow vertical rod of the frame 1.

[0056] Reference Figure 5 and Figure 6, the top wall of the sliding plug 42 is welded to the mounting rod 43. In this embodiment, there are three force transmission columns 44, which are distributed along the axial direction of the mounting rod 43. The force transmission column 44 includes a contact section 441, an anti-tilt ring piece 442 and two support bars 443. The mounting rod 43 is hollow, and a movable groove for the force transmission column 44 to move up and down is opened on the side of the mounting rod 43 close to the display frame 22. A strip groove 211 is opened on the L-shaped load-bearing angle steel, and the contact section 441 slides in the strip groove 211 along the opening direction of the strip groove 211. The contact section 441 and the anti-tilt ring piece 442 are coaxially welded; the two support bars 443 are evenly distributed along the circumference of the contact section 441, and the support bar 443 is welded to the contact section 441.

[0057] Reference Figure 5 , slide grooves 431 are welded on the two opposite inner side walls of the mounting rod 43, the setting direction of the slide groove 431 is consistent with the axial direction of the mounting rod 43, the anti-tilt ring 442 slides in the slide groove 431 along the axial direction of the mounting rod 43, and a plurality of layers of support members 432 are installed in the mounting rod 43 along its own axial direction. In this embodiment, the number of support members 432 is nine layers, and the nine layers of support members 432 are divided into three groups and are respectively arranged near three display frames 22. The support member 432 includes two support sheets 4321, which are respectively welded to the two opposite inner cavity walls of the mounting rod 43, and a gap is reserved between the two support sheets 4321 for the abutment section 441 to pass through.

[0058] Reference Figure 6 , Figure 7 as well as Figure 8 The control unit 5 includes an adjusting cylinder 51, a force applying rod 52, a rotating disk 53 and a piston disk 54. The adjusting cylinder 51 is a square cylinder. A plurality of water holes 511 are provided on the adjusting cylinder 51. In this embodiment, the number of the water holes 511 is two. The inner cavity of the adjusting cylinder 51 is connected with the inner cavity of the water tank 3 through the water holes 511. The piston disk 54 is slidably connected with the inner cavity wall of the adjusting cylinder 51. A accommodating space is formed between the piston disk 54 and the top wall of the adjusting cylinder 51, and an opening is set on the bottom wall of the adjusting cylinder 51.

[0059] Reference Figure 6 , Figure 7 as well as Figure 8 The top wall of the rotating disk 53 is welded to one end of the force rod 52, and the force rod 52 passes through the top wall of the adjusting cylinder 51 and is slidably connected to the top wall of the adjusting cylinder 51; the rotating disk 53 abuts against the piston disk 54 on the side away from the force rod 52, and two sliders are integrally connected to the piston disk 54. The rotating disk 53 is provided with an annular groove for the sliding of the sliders, so that the rotating disk 53 and the piston disk 54 can achieve relative rotation while maintaining abutment. In order to facilitate the discharge of water in the accommodating space, water outlet holes 55 are provided on the rotating disk 53 and the piston disk 54. After the water outlet holes 55 on the rotating disk 53 and the piston disk 54 are relatively rotated and aligned, the accommodating space is connected to the outside.

[0060] Reference Figure 6 , Figure 7 as well as Figure 8 In order to further facilitate the addition of water to and discharge of water from the water tank 3, two water suction pipes 6 are connected to the regulating cylinder 51. One end of the water suction pipe 6 is connected to the accommodating space through the water hole 511, and the other end passes through the bottom wall of the water tank 3 and extends to the outside. A through hole 61 is opened in the area of ​​the water suction pipe 6 close to the bottom wall of the water tank 3, and a one-way valve 62 is connected to the flange on the extended section of the water suction pipe 6 extending out of the water tank 3.

[0061] The implementation principle of a highly reliable display rack in Example 2 of the present application is as follows: push the display frame 22 onto the carrier frame 21, then place the exhibits in the display frame 22, then put the end of the water suction pipe 6 away from the adjusting cylinder 51 into the water, apply force to the force rod 52, the force rod 52 drives the piston rod to move toward the end away from the top wall of the adjusting cylinder 51 through the rotating disk 53, so that water is sucked into the water suction pipe 6, and then drive the force rod 52 in the reverse direction, so that the water in the water suction pipe 6 enters the water tank 3 through the through hole 61, the water in the water tank 3 applies force to the sliding plug 42 through the connecting pipe 41, the sliding plug 42 drives the supporting plate 4321 to move through the mounting rod 43, and the supporting plate 4321 drives the display frame 22 to rotate through the supporting bar 443, the abutting section 441 and the carrier frame 21 until the inclination angle of the display frame 22 is appropriate, stop absorbing water, and then push the frame 1 to the display position.

[0062] During display, if the customer takes the exhibit out of the display frame 22, the water pressure in the water tank 3 will push the sliding plug 42 up. While the sliding plug 42 rises, it drives the supporting frame 21 to rotate through the mounting rod 43 and the force transmission column 44, thereby changing the inclination angle of the display frame 22. By observing the inclination angle of the display frame 22, the staff can determine the amount of goods in the display frame 22 and replenish the goods in time.

[0063] When it is necessary to adjust the tilt angle of a certain display frame 22 separately, the display frame 22 is pulled out, and then the abutment section 441 is twisted. The abutment section 441 drives the anti-tilt ring piece 442 and the two support bars 443 to rotate with the abutment section 441 as the rotation axis until the support bar 443 is turned to be vertically distributed. At this time, the abutment section 441 and the support bar 443 pass through the gap between the two support pieces 4321, and the separate adjustment of the display frame 22 is completed.

[0064] When it is necessary to adjust the angle of the display frame 22 within a small range, force is applied to the force-applying rod 52, and the force-applying rod 52 drives the piston plate 54 to move along the long side direction of the adjustment cylinder 51 through the rotating plate 53. At this time, the water in the water tank 3 either enters the water tank 3 from the accommodating space or enters the accommodating space from the water tank 3, so that the force of the water in the water tank 3 acting on the sliding plug 42 changes, thereby fine-tuning the inclination angle of the display frame 22.

[0065] When it is necessary to discharge the water in the water tank 3, force is applied to the force rod 52 to make the piston disk 54 move toward the end away from the top wall of the regulating cylinder 51. The water in the water tank 3 enters the water suction pipe 6 through the through hole 61 and enters the accommodating space. Then the force rod 52 is twisted, and the force rod 52 drives the rotating disk 53 to rotate until the rotating disk 53 and the water outlet holes 55 on the piston disk 54 are facing each other. At this time, the water is discharged from the accommodating space to the outside through the water outlet holes 55.

[0066] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
