Description

Technical Field

[0001] This utility model belongs to the field of exhibition equipment technology, and specifically relates to an exhibition equipment with an adjustable support angle. Background Technology

[0002] Roll-up banners are widely used in conferences, exhibitions, sales promotions, and other occasions. They are one of the most frequently used, common, and portable display tools. The structure of a roll-up banner includes a box and an internal scroll. A base is installed at the bottom of the box, and a scroll pull-out port is located at the front of the upper edge of the box. An upward-facing support rod is installed at the middle of the rear of the upper edge of the box. When in use, the scroll is pulled out to form a vertical poster. The top of the poster is inserted and fixed to the top of the support rod, thus forming a vertical support. The bottom of the scroll has a spring tension. When fixed to the support rod, to balance the spring tension, the insertion hole at the bottom of the support rod is angled, keeping the support rod in a backward-tilting posture. However, existing methods for creating the insertion hole at the bottom of the support rod involve punching two holes—one upper and one lower—on the bent and welded box body, with the upper and lower insertion holes offset to achieve the tilt angle of the support rod; or punching the upper and lower insertion holes on a metal plate before the box body is bent and welded. The existing hole-making method has certain drawbacks. The processing accuracy is not good, and it cannot guarantee the positional correspondence between the upper and lower holes, resulting in a high scrap rate of the workpiece.

[0003] Furthermore, as the production standards of roll-up banner displays become increasingly internationalized, the requirements for poster verticality are becoming more stringent. With existing structures, the inconsistent tension of the scrolls leads to inconsistent tilt angles when the posters are erected. This results in poor aesthetics and uniformity when multiple roll-up banners are displayed simultaneously. Currently, when an inconsistent tilt angle is found among multiple posters, the only solution is to replace the poster with a new roll-up banner with similar scroll tension, and then reinstall and adjust it. This not only increases costs but is also time-consuming and labor-intensive, impacting the user experience of quickly setting up and displaying the banners. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an adjustable support angle display fixture. By setting an angle adjustment mechanism at the rear of the box, the angle of the support frame can be adjusted, thereby adjusting the upright angle of the poster and maintaining the verticality and consistency of the poster display.

[0005] The technical problem solved by this utility model is achieved through the following technical solution:

[0006] An adjustable support angle display device includes a box body, a support base, and a scroll. The support base is installed at the bottom of the box body, and the scroll is installed inside the box body. A scroll pull-out port is formed on the upper front edge of the box body. The device is characterized in that an adjustable support rod insertion mechanism is provided at the middle of the rear part of the box body. The adjustable support rod insertion mechanism includes a fixed plate, a lower insertion hole plate, and an upper insertion hole adjustment mechanism. The fixed plate is fixedly installed on the rear vertical surface of the box body. A lower insertion hole plate with a lower insertion hole is formed at the lower end of the fixed plate. The upper insertion hole adjustment mechanism includes an adjustment seat and an adjustment block. The adjustment seat is formed on the upper edge of the fixed plate. The adjustment block is adjustablely installed in the adjustment seat. Adjusting the adjustment block makes the axial position of the upper insertion hole and the axial position of the lower insertion hole eccentric in the front-rear position.

[0007] Furthermore, the adjusting seat is provided with a horizontal sliding groove, and the adjusting block is horizontally adjustable and inserted into the sliding groove of the adjusting seat. The adjusting block is provided with a vertical upper insertion hole. The adjusting block is horizontally slidably adjusted so that the axis position of the upper insertion hole is eccentric to the axis position of the lower insertion hole.

[0008] Furthermore, the side of the adjusting block is fitted with a horizontally forward-backward metal sleeve, which is fitted with a first adjusting bolt. The first adjusting bolt protrudes and is installed on the adjusting seat. Rotating the first adjusting bolt allows the adjusting block to move horizontally forward-backward.

[0009] Furthermore, the side of the adjusting block is provided with an inclined surface, and an inclined pressure block is installed in the adjusting seat. The inclined surface of the inclined pressure block contacts the inclined surface of the adjusting block. A second adjusting bolt is fixedly installed on the other side of the inclined pressure block. The second adjusting bolt is threaded onto the side of the adjusting seat. Rotating the second adjusting bolt tightens the adjusting block and thus compresses the adjusting block to move horizontally. A compression spring is installed in the adjusting seat on the side opposite to the inclined surface. When the second adjusting bolt is rotated to loosen the adjusting block, the adjusting block moves back horizontally under the pressure of the spring.

[0010] Furthermore, the adjusting block is horizontally slidably inserted into the adjusting seat, and a set screw is installed on the side of the adjusting seat. After adjusting the position of the adjusting block, the position of the adjusting block is fixed by the set screw.

[0011] Furthermore, the adjusting block is inserted into the adjusting seat, which has multiple spaced vertical positioning slots for locking, and the adjusting block has positioning teeth that engage with the positioning slots. The adjusting block is adjusted in a horizontal and backward manner on the adjusting seat by insertion.

[0012] Furthermore, the adjustment seat is equipped with a scale, and the adjustment block is equipped with a pointer, allowing the adjustment block to be precisely adjusted according to the scale position.

[0013] The advantages and beneficial effects of this utility model are as follows:

[0014] The adjustable support angle display fixture of this utility model has an adjustable support rod insertion mechanism at the middle of the rear of the box. The adjustable support rod insertion mechanism includes a fixed plate, a lower insertion hole plate, and an upper insertion hole adjustment mechanism. By adjusting the above-mentioned adjustment block, the axis position of the upper insertion hole is offset from the axis position of the lower insertion hole. When the bottom end of the support rod of the display fixture is inserted into the adjustable support rod insertion mechanism, the bottom end of the support rod is positioned at the lower insertion hole plate, and the upper part can be moved horizontally back and forth through the adjustment block, thereby adjusting the angle of the support rod. The upright angle of the poster on the scroll can be adjusted by adjusting the angle of the support rod.

[0015] The adjustable support angle display fixture of this utility model has a metal sleeve with a horizontal front-to-back direction on the side of the adjusting block.

Detailed Implementation

[0037] The present invention will be further described in detail below through specific embodiments. The following embodiments are only descriptive and not limiting, and should not be used to limit the protection scope of the present invention. Example

[0038] An adjustable support angle display fixture, such as Figures 1 to 5 As shown, the device includes a box body 1, a support base 4, and a scroll. The support base 4 is installed at the bottom of the box body 1, and the scroll is installed inside the box body 1. The two ends of the scroll are positioned with end caps 5 at both ends of the box body 1. The scroll installation structure is an existing structure and will not be described in detail. The support base 4 is installed at the bottom of the box body 1 via a rotating seat 3, which is also an existing structure. A poster 9 is attached to the scroll, and the upper end of the poster 9 is fixed to the horizontal bar 7 of the poster 9. A scroll pull-out outlet 2 is provided on the upper front edge of the box body 1. An adjustable support rod insertion mechanism 6 is provided at the middle of the rear of the box body 1. The adjustable support rod insertion mechanism 6 includes a fixing plate 12, a lower insertion hole plate 13, and an upper insertion hole adjustment mechanism 10. The fixing plate 12 is fixed to the rear vertical surface of the box body 1 with screws. A lower insertion hole plate 13 is provided at the lower end of the fixing plate 12, and the lower insertion hole plate 13 has a lower insertion hole position 14. The upper and lower edges of the fixing plate 12 have positioning edges, which are snapped onto the outer edge of the box body 1.

[0039] like Figures 6 to 10As shown, the upper insertion hole adjustment mechanism 10 includes an adjustment seat 11 and an adjustment block 16. The adjustment seat 11 is formed along the edge of the fixed plate 12, and has a horizontal sliding groove 19. The adjustment block 16 is horizontally adjustable and can be inserted into the sliding groove of the adjustment seat 11. The adjustment block 16 has a vertical upper insertion hole 15, and the adjustment seat 11 has a through groove 27 corresponding to the position of the upper insertion hole 15. The horizontal sliding adjustment of the adjustment block 16 causes the axis position 25 of the upper insertion hole 15 to be eccentrically positioned relative to the axis position 26 of the lower insertion hole 14. A horizontally forward-backward metal sleeve 18 is embedded in the side of the adjustment block 16. A first adjusting bolt 17 is mounted on the metal sleeve 18, which protrudes and is mounted on the adjustment seat 11. Rotating the first adjusting bolt 17 allows the adjustment block 16 to move horizontally forward-backward. Figure 10 The diagram shows the adjustment block 16 being adjusted to the horizontal rear.

[0040] The adjusting seat 11 is equipped with a scale 32, and the adjusting block 16 is equipped with a pointer 31. The adjusting block 16 is precisely adjusted according to the scale position. The position of the adjusting block 16 can be tested before leaving the factory, and the correspondence between the angle of the support rod 8 and the reference position of the adjusting block 16 is explained to facilitate quick adjustment by the user. Example

[0041] The upper insertion hole adjustment mechanism 10 adopts a wedge block adjustment structure. An inclined surface 21 is formed on the side of the adjustment block 16. An inclined surface pressure block 22 is installed inside the adjustment seat 11. The inclined surface of the pressure block 22 contacts the inclined surface of the adjustment block 16. A second adjustment bolt 24 is fixedly installed on the other side of the pressure block 22. The second adjustment bolt 24 is threaded onto the side of the adjustment seat 11 via a threaded seat 23. Rotating the second adjustment bolt 24 presses the adjustment block 16, thereby forcing the adjustment block 16 to move horizontally. A compression spring 20 is installed inside the adjustment seat 11 on the side opposite the inclined surface. When the second adjustment bolt 24 is rotated to release the adjustment block 16, the adjustment block 16 moves back horizontally under the spring pressure. This structure allows the second adjustment bolt 24 to be adjusted on the side of the adjustment seat 11, reducing the space occupied by the upper insertion hole adjustment mechanism 10 in the front-to-back direction, making it easier to store and carry. Figure 11 , 12 As shown. Example

[0042] The adjusting block 16 is horizontally slidably inserted into the adjusting seat 11. A set screw 28 is installed on the side of the adjusting seat 11. After adjusting the position of the adjusting block 16, the set screw 28 is used to fix the position of the adjusting block 16. The relative position of the upper insertion hole 15 and the lower insertion hole 14 can be achieved by manually adjusting the front and rear horizontal position of the adjusting block 16. The structure is simple. Figure 13 As shown. Example

[0043] The adjusting block 16 is inserted into the adjusting seat 11. The adjusting seat 11 has multiple vertical positioning grooves 30 arranged at intervals. The adjusting block 16 has positioning teeth 29 that engage with the vertical positioning grooves 30. The adjusting block 16 is inserted into the adjusting seat 11 to adjust its horizontal position. After the adjusting block (16) is pulled out upwards, its position is moved and then it is inserted back into the adjusting seat 11, which can adjust the relative position of the upper insertion hole 15 and the lower insertion hole 14.

[0044] When the bottom end of the support rod 8 of the display stand is inserted into the adjustable support rod insertion mechanism 6, the bottom end of the support rod 8 is positioned in the lower insertion plate 13. The horizontal back-and-forth position can be moved by the adjustment block 16, thereby adjusting the angle of the support rod 8. The support rod 8 can be a multi-section support rod 8 or a telescopic rod. The upper end of the support rod 8 is inserted into the horizontal bar 7 of the poster 9. The vertical angle of the poster 9 on the scroll can be adjusted by adjusting the angle of the lower part of the support rod 8. Since the strength of the scroll in each roll-up banner display stand box 1 is different, by adjusting the tilt angle of the support rod 8, the vertical surface of the poster 9 of the roll-up banner display stand can be kept consistent, and it should be as vertical as possible or slightly tilted backward to achieve an aesthetic display.
