The support rod sleeve 3 is equipped with a snap-fit ​​component. The inner end of the snap-fit ​​component is used to snap onto the lifting support rod 6.

[0025] In this embodiment, the top and bottom of the spare plate 21 are provided with sliding grooves 211 along the length direction, and the vertical cross section of the sliding groove 211 is T-shaped. The sliding limiting component 18 includes a fixed rod 181, a swing arm 182, a connecting rod 183 and a locking block 184. The fixed rod 181 is fixed to the top or bottom of the inner end of the main plate 2. One end of the swing arm 182 is rotatably sleeved on the top of the fixed rod 181. The other end of the swing arm 182 is vertically fixedly connected to the connecting rod 183. The other end of the connecting rod 183 is rotatably connected to the locking block 184. The locking block 184 is slidably disposed in the sliding groove 211.

[0026] In this embodiment, the top side of the lifting support rod 6 is provided with a through insertion hole 11. An insertion rod 8 is rotatably inserted into the insertion hole 11. The inner end of the insertion rod 8 located inside the insertion hole 11 is fixed to the outer side of the fixed bracket 7. The outer end of the insertion rod 8 located outside the insertion hole 11 is provided with a threaded section. A retaining ring 9 is fixedly sleeved on the insertion rod 8 inside the threaded section. When the retaining ring 9 abuts against the inner side of the lifting support rod 6, a fixing nut 10 is threadedly sleeved on the threaded section located outside the insertion hole 11. Rotating the insertion rod 8 can adjust the display angle of the main board 2, and locking is applied by the fixing nut 10.

[0027] In this embodiment, the outer side of the lifting support rod 6 is provided with several slots 12 vertically at equal intervals. The top of the support rod sleeve 3 near the slot 12 is provided with a limiting groove 13. The locking assembly includes a support frame 14, a pull rod 16, a spring 17 and a locking block 15. The support frame 14 is fixed on the support rod sleeve 3 outside the limiting groove 13. The pull rod 16 is movably inserted into the support frame 14, and the locking block 15 is fixed on the inner end of the pull rod 16 inside the support frame 14. A spring 17 is connected between the locking block 15 and the support frame 14. The spring 17 is sleeved on the pull rod 16. The outer end of the pull rod 16 is fixed with a pull bar. When the spring 17 is in its natural state, the locking block 15 passes through the limiting groove 13 and is inserted into one of its slots 12.

[0028] In this embodiment, the top of the locking block 15 is a horizontal plane, and the bottom of the locking block 15 is set as an inclined surface with a lower outer surface and a higher inner surface. The slot 12 is set as an inclined groove that cooperates with the inclined surface of the locking block 15. The engagement design of the slot 12 and the locking block 15 facilitates height adjustment. The elastic potential energy of the spring 17 keeps the locking block 15 engaged in the slot 12, ensuring that the lifting support rod 6 will not automatically descend after the height is adjusted.

[0029] In this embodiment, magnetic absorbing pieces 22 are rotatably provided on both sides of the back of the backup plate 21. When the backup plate 21 is located between two main plates 2, the outer ends of the two magnetic absorbing pieces 22 are used to magnetically connect to the back of the main plates 2 at both ends respectively.

[0030] Working Principle: During use, the display device is first assembled according to the size of the drawing to be displayed. When the drawing size is small, the spare plate 21 is manually slid to the back of the two main plates 2, and the spare plate 21 is in a retracted state. When the drawing size is large, the support adjustment components 1 on both sides are pulled outwards, causing the two main plates 2 to move to the sides and pushing the spare plate 21 forward, so that the spare plate 21 and the two main plates 2 are on the same vertical plane. The magnetic suction pieces 22 on both sides of the back of the spare plate 21 are rotated, so that the outer ends of the magnetic suction pieces 22 are magnetically fixed to the back of the corresponding main plate 2. At this time, the spare plate 21 is in the use state. Then, the main plate 2 is fixed to the fixed bracket 7 by the fixing screw 19. The outer end of the plug-in rod 8 is inserted into the plug-in hole 11 by external force, and the threaded section of the plug-in rod 8 is connected by the fixing nut 10. Then, the height of the main plate 2 is adjusted according to the required height. When it needs to be raised, the two lifting support rods 6 are pulled upwards to the required height by external force. When the lifting support rods 6 move upwards, the slot 12... The locking block 15 is pressed and moved outward away from the lifting support rod 6. The locking block 15 compresses the spring 17 and retracts. When the lifting support rod 6 moves to the required height, the spring 17 rebounds and presses the locking block 15 into the corresponding height slot 12. When the main board 2 needs to be lowered, the two pull rings are pulled simultaneously by external force. The pull rings drive the pull rod 16 away from the support rod sleeve 3. The movement of the pull rod 16 causes the locking block 15 to move away from the slot 12. The movement of the locking block 15 compresses the spring 17 and retracts. At this time, the lifting support rod 6 can be pushed down to the required height by external force. Then, the force applied to the pull rod 16 is removed. At this time, the spring 17 rebounds and pushes the locking block 15 into the corresponding height slot 12. Then, the angle of the display device is adjusted as needed. The main board 2 is rotated to the required angle by external force. Then, the fixing nut 10 is tightened by external force and brought closer to the lifting support rod 6 until the fixing nut 10 is tightly attached to the outside of the lifting support rod 6 to fix the fixing bracket 7. At this time, the drawings can be attached to the main board 2 and the spare board 21 by magnetic snap for display and viewing.

[0031] This utility model, through the combined design of two main boards 2 and a backup board 21, can quickly adjust the display area according to the actual size of the drawings. Whether it is a small partial drawing or a large overall planning drawing, it can be flexibly displayed. At the same time, the height of the main board 2 can be adjusted according to the support adjustment component 1. Construction personnel can rotate the fixed bracket 7 according to the actual situation to adjust the display angle of the main board 2, ensuring that the drawing content is easy to display and view, and improving the convenience and efficiency of viewing drawings during the construction process.

[0032] The above description is only a preferred embodiment of the present utility model and does not limit the scope of the present utility model.
