Technical Field

[0001] This utility model belongs to the field of advertising equipment technology, and in particular relates to an advertising tool with a telescopic structure. Background Technology

[0002] In daily campus management and activities, publicity tools are an important carrier for conveying information.

[0003] However, existing campus publicity tools have the following shortcomings:

[0004] Poor size adaptability: Most promotional tools are designed with a fixed size. When different sizes of display boards are needed, display racks of different sizes must be replaced, which not only increases equipment costs but also reduces the efficiency of promotional preparation.

[0005] Fixed display angles: The display angles of existing promotional tools are mostly non-adjustable or require cumbersome adjustment steps. The flow of people on campus is flexible (such as the entrance to the cafeteria, the entrance to the playground, and the corridor of the teaching building). Fixed angles make it difficult to ensure that people from different directions can clearly obtain the promotional information, which affects the promotional effect.

[0006] Therefore, it is necessary to provide a new advertising tool with a telescopic structure to solve the above-mentioned technical problems. Utility Model Content

[0007] The technical problem solved by this utility model is to provide a promotional tool with a telescopic structure that can be flexibly extended to adapt to display panels of different sizes, can quickly adjust the display angle, take into account both convenient movement and stable fixation, and can firmly fix the display panel.

[0008] To solve the above-mentioned technical problems, the publicity tool with a telescopic structure provided by this utility model includes: a support mechanism, a telescopic mechanism, an adjustment mechanism, and two pressing mechanisms;

[0009] The support mechanism includes an I-shaped base, a circular part, a support rod, a fixed plate, and a horizontal plate. The bottom of the I-shaped base is fixedly equipped with four self-locking casters with brakes. The circular part is located in the middle of the I-shaped base. The support rod is rotatably mounted on the top center of the circular part. The fixed plate is fixedly sleeved on the support rod. The horizontal plate is fixedly mounted on the top of the support rod.

[0010] The telescopic mechanism includes a display panel, two long telescopic sleeves, four long telescopic rods, four corner blocks, four short telescopic rods, two short telescopic sleeves, and four tension springs. The display panel is positioned above the horizontal plate. The two long telescopic sleeves are respectively positioned at the top and bottom of the display panel. The lower long telescopic sleeve is connected to the horizontal plate with fixing bolts. The four long telescopic rods are slidably installed inside the two long telescopic sleeves. The four corner blocks are fixedly installed at one end of the four long telescopic rods. The four short telescopic rods are fixedly installed on the sides of the four corner blocks that are close to each other. The two short telescopic sleeves are respectively fitted onto the four short telescopic rods. The four tension springs are respectively positioned inside the two long telescopic sleeves and the two short telescopic sleeves. The two ends of the four tension springs are fixedly connected to the corresponding long telescopic rods and short telescopic rods.

[0011] As a further embodiment of this utility model, the adjusting mechanism includes a fixed sleeve, an L-shaped pull rod, a circular plate, a return spring, and multiple insertion holes. The fixed sleeve is fixedly installed on the top of the fixed plate, the L-shaped pull rod is slidably installed inside the fixed sleeve, the circular plate is fixedly sleeved on the L-shaped pull rod, and the return spring is sleeved on the L-shaped pull rod. The two ends of the return spring are respectively fixedly connected to the top of the circular plate and the inner wall of the fixed sleeve. The multiple insertion holes are all opened on the circular part, and the multiple insertion holes are arranged in a ring, with the bottom end of the L-shaped pull rod inserted into the corresponding insertion hole.

[0012] As a further embodiment of this utility model, the clamping mechanism includes a T-shaped plate, an adjusting screw, a pressure plate, a knob, two fixing blocks, and a positioning bolt. The T-shaped plate is hinged to the back of the long telescopic sleeve, the adjusting screw is threaded onto the T-shaped plate, the pressure plate is rotatably mounted on one end of the adjusting screw, the knob is fixedly mounted on the other end of the adjusting screw, both fixing blocks are fixedly mounted on the back of the long telescopic sleeve, and the positioning bolt is mounted on the two fixing blocks, with the positioning bolt penetrating the T-shaped plate.

[0013] As a further embodiment of this utility model, baffles are fixedly installed on the two long telescopic sleeves and the two short telescopic sleeves, and the baffles are in contact with the display panel.

[0014] As a further embodiment of this utility model, a plurality of rolling balls are installed on the circular part, the rolling balls are distributed around the outside of the insertion hole, and the top of the rolling balls is in contact with the fixing plate.

[0015] As a further embodiment of this utility model, two limiting rods are fixedly installed on the pressure plate, and the limiting rods pass through the T-shaped plate and are slidably connected to the T-shaped plate.

[0016] Compared with related technologies, the advertising tool with a telescopic structure provided by this utility model has the following beneficial effects:

[0017] 1. This utility model achieves size adjustment by setting a telescopic mechanism. When the long telescopic sleeve and the short telescopic sleeve are pulled, the long telescopic rod and the short telescopic rod slide along the sleeve body and stretch the tension spring. After the display panel is placed, it is released, and the tension spring resets and drives the telescopic component to clamp the display panel. It can be adapted to campus publicity posters of different specifications, reduce equipment costs, and improve publicity preparation efficiency.

[0018] 2. This utility model features an adjustment mechanism. By cooperating with the reset spring and the annular insertion hole, pulling up the L-shaped pull rod releases the angle lock, rotating the support rod adjusts the display direction, and releasing the L-shaped pull rod automatically inserts into the corresponding insertion hole to complete the fixation. The angle can be quickly adjusted according to the direction of pedestrian flow on campus (such as the entrance of the canteen or the direction of the playground stands) to ensure that the promotional information can be clearly obtained by pedestrians from multiple directions.

[0019] 3. This utility model uses a pressing mechanism to adjust the screw by turning a knob, which pushes the pressure plate to press the display panel. The limiting rod ensures that the pressure plate moves only in a straight line to avoid deviation. Attached Figure Description

[0028] Please refer to the following: Figures 1 to 6 ,in, Figure 1 A schematic diagram of the overall structure of the promotional tool with a telescopic structure provided by this utility model; Figure 2 This is a schematic diagram of the support mechanism in this utility model; Figure 3 This is a schematic diagram of the telescopic mechanism in this utility model; Figure 4 This is a cross-sectional view of the medium-length telescopic sleeve of this utility model; Figure 5 This is a cross-sectional view of the adjustment mechanism in this utility model; Figure 6 This is a schematic diagram of the clamping mechanism in this utility model. The promotional tool with a telescopic structure includes: a support mechanism, a telescopic mechanism, an adjustment mechanism, and two clamping mechanisms;

[0029] The support mechanism includes an I-shaped base 1, a circular part 2, a support rod 3, a fixing plate 4, and a horizontal plate 5. The bottom of the I-shaped base 1 is fixedly equipped with four self-locking casters with brakes. The circular part 2 is located in the middle of the I-shaped base 1. The support rod 3 is rotatably mounted on the top center of the circular part 2. The fixing plate 4 is fixedly sleeved on the support rod 3. The horizontal plate 5 is fixedly mounted on the top of the support rod 3.

[0030] The telescopic mechanism includes a display panel 6, two long telescopic sleeves 7, four long telescopic rods 8, four corner blocks 9, four short telescopic rods 10, two short telescopic sleeves 11, and four tension springs 12. The display panel 6 is positioned above the horizontal plate 5. The two long telescopic sleeves 7 are respectively positioned at the top and bottom of the display panel 6. The lower long telescopic sleeve 7 is connected to the horizontal plate 5 with fixing bolts. The four long telescopic rods 8 are slidably installed inside the two long telescopic sleeves 7. The four corner blocks 9 are respectively fixedly installed at one end of the four long telescopic rods 8. The four short telescopic rods 10 are respectively fixedly installed on the side of the four corner blocks 9 that are close to each other. The two short telescopic sleeves 11 are respectively fitted onto the four short telescopic rods 10. The four tension springs 12 are respectively positioned inside the two long telescopic sleeves 7 and the two short telescopic sleeves 11. The two ends of the four tension springs 12 are respectively fixedly connected to the corresponding long telescopic rods 8 and short telescopic rods 10.

[0031] like Figure 5As shown, the adjustment mechanism includes a fixed sleeve 13, an L-shaped pull rod 14, a circular plate 15, a return spring 16, and multiple insertion holes 17. The fixed sleeve 13 is fixedly installed on the top of the fixed plate 4. The L-shaped pull rod 14 is slidably installed inside the fixed sleeve 13. The circular plate 15 is fixedly sleeved on the L-shaped pull rod 14. The return spring 16 is sleeved on the L-shaped pull rod 14. The two ends of the return spring 16 are fixedly connected to the top of the circular plate 15 and the inner wall of the fixed sleeve 13, respectively. Multiple insertion holes 17 are all opened on the circular part 2. The multiple insertion holes 17 are arranged in a ring and the bottom end of the L-shaped pull rod 14 is inserted into the corresponding insertion hole 17.

[0032] By pulling the L-shaped lever 14 to compress the reset spring 16, the bottom end of the L-shaped lever 14 is disengaged from the insertion hole 17. After rotating the support rod 3 to the desired angle, the L-shaped lever 14 is released, and the reset spring 16 resets and pushes the L-shaped lever 14 into the corresponding insertion hole 17, thereby achieving rapid adjustment and fixation of the display angle.

[0033] like Figure 6 As shown, the clamping mechanism includes a T-shaped plate 18, an adjusting screw 19, a pressure plate 20, a knob 21, two fixing blocks 22, and a positioning bolt 23. The T-shaped plate 18 is hinged to the back of the long telescopic sleeve 7. The adjusting screw 19 is threaded onto the T-shaped plate 18. The pressure plate 20 is rotatably mounted on one end of the adjusting screw 19. The knob 21 is fixedly mounted on the other end of the adjusting screw 19. Both fixing blocks 22 are fixedly mounted on the back of the long telescopic sleeve 7. The positioning bolt 23 is mounted on the two fixing blocks 22 and passes through the T-shaped plate 18.

[0034] Adjust the angle of the T-shaped plate 18 by loosening the positioning bolt 23, tighten the positioning bolt 23 to fix the T-shaped plate 18, and then turn the knob 21 to drive the adjusting screw 19 to push the pressure plate 20 to press the display panel 6, thereby achieving a stable fixation of the display panel 6.

[0035] like Figure 1 and Figure 3 As shown, baffles 24 are fixedly installed on the two long telescopic sleeves 7 and the two short telescopic sleeves 11, and the baffles 24 are in contact with the display panel 6.

[0036] The baffle 24 positions the display panel 6 to prevent it from shifting laterally during telescopic adjustment or movement, thus ensuring a stable display position.

[0037] like Figure 5 As shown, a plurality of balls 25 are mounted on the circular part 2. The balls 25 are distributed around the outside of the insertion hole 17, and the top of the balls 25 is in contact with the fixing plate 4.

[0038] The rolling ball 25 converts the sliding friction between the fixed plate 4 and the circular part 2 into rolling friction, reducing frictional resistance and making the support rod 3 drive the fixed plate 4 and the display panel 6 to rotate more smoothly, reducing the operating force when adjusting the angle.

[0039] like Figure 6 As shown, two limiting rods 26 are fixedly installed on the pressure plate 20. The limiting rods 26 pass through the T-shaped plate 18 and are slidably connected to the T-shaped plate 18.

[0040] The limit rod 26 restricts the rotation of the pressure plate 20, ensuring that when the adjusting screw 19 rotates, the pressure plate 20 only moves in a straight line, thus preventing the pressure plate 20 from shifting and causing the display panel 6 to be unstable.

[0041] The working principle of the advertising tool with a telescopic structure provided by this utility model is as follows:

[0042] First step: Unlock the self-locking universal wheel brake at the bottom of the I-shaped base 1. The student pushes the tool to the target site (such as the playground for sports meet publicity). After arriving, step on the brake to fix the universal wheel and prevent the tool from moving in the flow of people on campus.

[0043] Second step: According to the size of the display panel 6, pull the two long telescopic sleeves 7 and the short telescopic sleeve 11 outward to allow the internal tension spring 12 to store energy. Then, place the display panel 6 between the two long telescopic sleeves 7 and the short telescopic sleeve 11, and release the long telescopic sleeves 7 and the short telescopic sleeve 11. Under the action of the tension spring 12, the two long telescopic sleeves 7 and the short telescopic sleeve 11 are clamped on the display panel 6.

[0044] Third step: Flip the T-shaped plate 18 so that it fits tightly against the long telescopic sleeve 7. Then, fix it by passing the positioning bolt 23 through the two fixing blocks 22 and the T-shaped plate 18. Then, turn the knob 21 and adjust the screw 19 to push the anti-slip pressure plate 20 to press the display panel 6 and fix the display panel 6.

[0045] Fourth step: Pull up the L-shaped lever 14, compress the return spring 16, and disengage the bottom end of the L-shaped lever 14 from the socket 17. Push the support rod 3 to rotate the display panel 6 (with the ball 25 assisting in the sliding), and adjust it to face the direction of campus pedestrian flow (such as the cafeteria entrance facing the entrance). Release the L-shaped lever 14, reset the return spring 16, and insert the bottom end of the L-shaped lever 14 into the corresponding socket 17 to complete the angle fixation.
