Description

Technical Field

[0001] The utility model relates to the technical field of training display racks, in particular to an education and training display rack. Background Art

[0002] During the education and training process, the display stand is used as a teaching information display tool to display relevant teaching content and teaching highlights, allowing the trainees to understand the content more quickly.

[0003] At present, most display racks cannot be moved, and their use is limited and inconvenient. In order to facilitate the movement of the display rack, some display racks are provided with rollers at the bottom to facilitate the movement of the display rack. However, in actual use, the rollers cannot be locked well when the display rack stops moving. Since the display rack is a panel, it is easy to be overturned due to the unstable center of gravity caused by external force, resulting in the risk of using the display rack. For example: Chinese utility model patent with publication number CN215730719U discloses a teaching display stand with stable support. Although it has good support stability and is not easy to tip over, the display stand is not easy to move, and it takes time and effort to move, so it is not very convenient to use; Chinese utility model patent with publication number CN217347295U discloses an information display stand for smart campus teaching management. The display stand can be stably fixed when it is moved to the ground under the action of a support plate, a threaded sleeve and a spiral nail rod. It can be used on uneven terrain to prevent the display stand from being displaced or tipped over. However, the display stand is not suitable for use on conventional flat ground.

[0038] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0039] As shown~ Figure 4 As shown, the embodiment of the utility model application provides an education and training display stand, including: a base 1, a display stand body 2, rollers 3, a fixing seat 4 and a limiting member 5.

[0040] The display stand body 2 is arranged on the upper surface of the base 1, the roller 3 is arranged on the lower surface of the base 1, a fixed seat 4 is movably arranged on one side of the roller 3, and a limiting member 5 is arranged on one side of the fixed seat 4. The base 1 and the display stand body 2 on the base 1 can be driven to move by pushing the roller 3 to roll, and when the display stand body 2 on the base 1 is moved to a designated location, the limiting member 5 on the fixed seat 4 is released, and the fixed seat 4 moves downward to fit the ground, thereby reducing the phenomenon of the display stand tipping over due to unstable center of gravity due to collision and other factors during use, and improving the stability of the display stand.

[0041] Specifically,

[0042] The base 1 includes a horizontal plate 11 and bosses 12 arranged at both ends of the bottom of the horizontal plate 11. The display rack body 2 is arranged on the horizontal plate 11, and rollers 3 are respectively installed on the two bosses 12. The outer sides of the two rollers 3 are respectively provided with fixed seats 4. The lower surface of the boss 12 is provided with a mounting groove 121, and the upper end of the mounting groove 121 extends to the horizontal plate 11. The fixed seat 4 is telescopically arranged in the mounting groove 121, and the fixed seat 4 can be in contact with the ground or away from the ground. The limiting member 5 is arranged on one side of the fixed seat 4. When the display rack needs to be moved, the fixed seat 4 is kept away from the ground by the limiting member 5.

[0043] Furthermore, the fixing seat 4 includes a column 41 , the top end of which is connected to the top wall of the mounting groove 121 via a first spring 42 , and the lower end of which is connected to a supporting horizontal plate 43 .

[0044] Optionally, the fixing seat 4 also includes a slide plate 44, which is slidably disposed in the mounting groove 121, the upper end of the column 41 is connected to the slide plate 44, one end of the first spring 42 is connected to the top of the slide plate 44, and the other end is connected to the top wall of the mounting groove 121.

[0045] Optionally, a rubber layer 45 is provided on the lower surface of the supporting transverse plate 43 .

[0046] A limiting groove 122 is provided on the side wall of the boss 12 on one side of the installation groove 121. Specifically, the limiting groove 122 is provided on the outer side wall of the boss 12, and has through holes at both ends of the limiting groove 122. The sizes of the two through holes are smaller than the size of the limiting groove 122. The limiting groove 122 is connected to the installation groove 121 through the through hole at the left end. The limiting member 5 is disposed in the limiting groove 122.

[0047] The limiting member 5 includes a movable rod 51 , a pull ring 52 , a connecting plate 53 , a limiting column 54 and a second spring 55 .

[0048] The movable rod 51 is movably arranged in the limiting groove 122, one end of which passes through the right through hole to extend to the outside of the boss 12 and is connected to the pull ring 52 arranged on the outside of the boss 12, the other end of the movable rod 51 is connected to a side wall of the connecting plate 53, one end of the limiting column 54 is connected to the other side of the connecting plate 53, and the other end passes through the left through hole to extend into the installation groove 121, the size of the connecting plate 53 is larger than the size of the through hole, that is, the connecting plate 53 is limited in the limiting groove 122, and the second spring 55 is sleeved on the movable rod 51 in the limiting groove 122. Optionally, one end of the second spring 55 is connected to the connecting plate 53, and the other end is connected to the side wall of the limiting groove corresponding to the connecting plate 53.

[0049] During the setting, when the first spring 42 is not compressed, the elastic force of the first spring 42 can make the supporting horizontal plate 43 fit the ground. When the second spring 55 is not compressed, the elastic force of the second spring 55 can make the limiting column 54 protrude from the installation groove 121 and partially overlap with the cross bar 46. Optionally, the elastic force of the second spring 55 can make the limiting column 54 abut against the column 41. When it is necessary to move the supporting cross plate 43 away from the ground, pull the pull ring 52, and the pull ring 52 drives the movable rod 51 to move toward the outside of the boss 12, and the connecting plate 53 compresses the second spring 55. At this time, the limit column 54 does not protrude from the installation groove 121, and then the column 41 is pushed upward. When the cross bar 46 moves to above the limit column 54, stop pulling the pull ring 52. At this time, the limit column 54 is extended into the installation groove 121 through the restoring force of the second spring 55, thereby limiting the cross bar 46, that is, the cross bar 46 is restricted above the limit column 54, so that the supporting cross plate 43 is away from the ground and no longer fits the ground. At this time, the display rack body 2 can be pushed to drive the display rack to move through the roller 3. When it is moved to a designated location for training and demonstration, the pull ring 52 is pulled, and the pull ring 52 drives the movable rod 51 to move toward the outside of the boss 12, and the connecting plate 53 compresses the second spring 55, so that the limit column 54 does not protrude from the installation groove 121. At this time, since the cross bar 46 is not restricted by the limit column, the elastic potential energy of the first spring 42 is released, pushing the column 41 to move downward, so that the rubber layer 45 at the bottom of the supporting cross plate 43 fits with the ground.

[0050] In one embodiment, the display rack body 2 includes a support column 21 , a top plate 22 , a panel 23 and a storage platform 24 .

[0051] The two pillars 21 are symmetrically arranged at the two ends of the horizontal plate 11, and the top plate 22 is arranged at the top of the two pillars 21. One end of the pillar 21 is connected to the upper surface of the horizontal plate 11, and the other end is connected to the top plate 22. The panel 23 is slidably arranged between the two pillars 21, and the storage table 24 is arranged on the outer wall of the pillar 21.

[0052] As an implementation scenario, in this scenario, the sliding mode of the panel 23 can be driven by an existing driving mechanism, that is, the driving mechanism is connected to the panel driving, and the panel can move up or down under the drive of the driving mechanism. Exemplarily, the driving mechanism is a lifting cylinder, the movable end of the cylinder is connected to the panel 23, and the two ends of the panel 23 are slidably connected to the support 21.

[0053] As another implementation scenario, in this scenario, a slide rail is provided on the side wall opposite to the pillar 21, and both ends of the panel 23 are slidably connected to the pillar 21 through sliders. In this embodiment, thorns are provided in the slide rail. When in use, the panel 23 can be moved to a specified position by moving it up or down and positioned by the thorns on the slide rail.

[0054] In one embodiment, in order to further increase the stability of the display rack during use, in this embodiment, a reinforcing transverse plate 6 is disposed on the transverse plate 11 , and the reinforcing transverse plate 6 can be raised and lowered by a driving member 7 .

[0055] Optionally, the reinforcing horizontal plate 6 is arranged perpendicular to the horizontal plate 11. By setting the reinforcing horizontal plate, the contact area between the display rack and the ground can be increased, and the stability of the display rack can be further improved to prevent the display rack from being tilted due to unstable center of gravity caused by external force.

[0056] Optionally, a rubber layer is provided at the bottom of the reinforcing transverse plate 6 .

[0057] As an implementation scenario, in this scenario, the driving member 7 is a screw threadedly connected to the horizontal plate 11. Specifically, a threaded hole is provided at the middle position of the horizontal plate 11, and a screw is threadedly connected in the threaded hole. The lower end of the screw is connected to the reinforcement horizontal plate 6 below the horizontal plate 11, and the upper end of the screw is connected to a turntable. When in use, by rotating the turntable, the screw can drive the reinforcement horizontal plate 6 to move downward so that it contacts the ground.

[0058] As another implementation scenario, in this scenario, the driving member 7 adopts an electric telescopic rod, which is installed on the cross plate 11, and its movable end is connected to the reinforced cross plate 6. The reinforced cross plate 6 can contact the ground under the drive of the electric telescopic rod.

[0059] In one embodiment, the roller 3 may also be a universal wheel with a brake, and the stability of the display stand can be further improved by adding a fixing seat 4.

[0060] A method of using an education and training display stand:

[0061] After the display rack is moved to the designated location by the roller 3, first, the pull ring 52 is pulled, and the pull ring 52 drives the movable rod 51 to move toward the outside of the boss 12, and the connecting plate 53 compresses the second spring 55, so that the limit column 54 does not protrude from the installation groove 121. At this time, the cross bar 46 located above the limit column 54 loses the restriction of the limit column 54, and the elastic potential energy of the first spring 42 is released, pushing the column 41 to move downward, and the cross bar 46 also moves synchronously to the bottom of the limit column 54, supporting the rubber layer 45 at the bottom of the horizontal plate 43 to fit the ground, and then release the pull ring 52. Then, the reinforcing horizontal plate 6 is driven downward by the driving member 7 so that the bottom of the reinforcing horizontal plate 6 also fits the ground.

[0062] After the display rack is used, first, the reinforcing horizontal plate 6 is moved away from the ground through the driving member 7 and no longer in contact with the ground. Then, the pull ring 52 is pulled, and the pull ring 52 drives the movable rod 51 to move to the outside of the boss 12, and the connecting plate 53 compresses the second spring 55, so that the limiting column 54 does not protrude from the installation groove 121, and then the column 41 is pushed upward. When the cross bar 46 moves to the top of the limiting column 54, the pull ring 52 is stopped. At this time, the second spring 55 pushes the limiting column 54 to extend into the installation groove 121 and is located below the cross bar 46 through the restoring force of the second spring 55, so that the cross bar 46 is limited above the limiting column 54. At this time, the supporting horizontal plate 43 is away from the ground and no longer in contact with the ground, and then the display rack body 2 is pushed, and the roller 3 drives the display rack to move to the storage location.

[0063] Parts not described in detail in this embodiment are well-known techniques in the art.

[0064] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
