Description

Technical Field

[0001] This utility model relates to the field of poster holder technology, specifically a poster hanging stand. Background Technology

[0002] Poster stands are used to display posters and information. Common poster stands are V-shaped, board-shaped, and X-shaped structures.

[0003] Posters come in a variety of materials, including paper, plastic, and fabric. Paper posters are often pasted on, while plastic and fabric posters require a hanging frame.

[0004] When hanging a poster, it needs to be laid flat. The poster can be hung on the four corners of the X-shaped frame by using the pre-set hooks at the four corners. Most of the current X-shaped frames use rigid rods, while some use elastic rods, such as spring steel, which can bend slightly when subjected to external force to enhance the stability of the poster when it is spread out.

[0005] However, the elastic rod has a limited range of deformation, and it cannot adapt to large changes in the size of the poster image by deforming the elastic rod alone. Utility Model Content

[0006] (I) Technical Issues

[0007] The present invention aims to at least solve the problem that the elastic support rod of the X-shaped frame in the prior art cannot adapt to changes in the size of the poster image when needed by changing the support tension without significant changes.

[0008] (II) Technical Content

[0009] This solution provides a poster hanging frame, achieved through the following specific technical means: including...

[0010] The base serves as the foundation for the entire structure.

[0011] A base plate is installed on the top of the support, and four sets of support rods are connected circumferentially to the base plate;

[0012] The support rod is formed by connecting a rigid rod head and a spring rod. The head end of the rigid rod head is hinged to the base plate, and a hook is fixed to the front side of the tail end of the spring rod.

[0013] The support angle adjustment mechanism is set on the base plate and connected to multiple sets of rigid rods. It is used to control the change of the angle between the multiple sets of elastic rods and the base plate when no force is applied, that is, to control the spacing between the tail ends of the multiple sets of elastic rods.

[0014] Preferred technical solution 1: The support angle adjustment mechanism includes a worm gear fixed to the end of a rigid rod and a worm rotatably installed at the center of the base plate. Four sets of worm gears connected to four sets of support rods surround the worm and mesh with the worm at the same time.

[0015] Preferred technical solution 2: A protruding arm is fixed on both the left and right sides of the base. The rear end of the protruding arm is rotatably connected to the top of the stand. The base drives the protruding arm to rotate on the stand to change the display angle of the poster.

[0016] Preferred technical solution 3: In order to maintain stability, the rear end of each group of protruding arms is rotatably sleeved on the internal threaded sleeve fixed on one side of the top of the stand;

[0017] At the same time, the bolt head of the bolt screwed into the internal thread sleeve presses down on the convex arm. By tightening the bolt, the convex arm can be pressed and fixed, thereby fixing the posture of the base plate.

[0018] Preferred technical solution four: A handle is connected between the two sets of bolts, and the bolts are driven simultaneously by the handle.

[0019] (III) Technical Effects

[0020] The above structure gives this solution the following advantages:

[0021] 1. It can adapt to large changes in poster size, and can also provide supporting tension to the poster using small deformations;

[0022] 2. The display angle is adjustable; Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-2 The poster hanging frame includes a stand 1, a base 5, and a support angle adjustment mechanism 7, wherein:

[0031] The bottom of the stand 1 is placed on the ground. The support provided by the weight of the stand 1 ensures that the center of gravity of the poster hanging stand is always directly above the stand 1, preventing the center of gravity from shifting too much and causing it to tip over.

[0032] The base plate 5 is installed on the top of the stand 1, and four sets of support rods 6 are connected circumferentially to the base plate 5. The support rods 6 include rigid rod heads 61 and elastic rods 62. The mounting shaft fixed at the head end of the rigid rod head 61 is rotatably connected to the base plate 5. At the same time, the tail end of the rigid rod head 61 is fixed to the head end of the elastic rod 62, and a hook is fixed on the front side of the tail end of the elastic rod 62. The pre-set hanging holes at the four corners of the poster are respectively hung on the hooks at the tail ends of the four sets of elastic rods 62.

[0033] In one embodiment: the hook can be replaced by a clip, which is hinged to the end of the spring bar 62.

[0034] An angle adjustment mechanism 7 is set on the base plate 5 and is simultaneously connected to multiple sets of rigid rod heads 61. It is used to control the angle change between the multiple sets of elastic rods 62 and the base plate 5 when no force is applied. In other words, it is used to control the spacing between the tail ends of the multiple sets of elastic rods 62, so that the rectangle formed by the tail ends of the four sets of elastic rods 62 is close to the size of the rectangle of the poster image, preferably slightly larger, so that it can provide support tension for the poster after it is hung up, ensuring that the poster unfolds.

[0035] In one embodiment:

[0036] Please see Figure 2 , Figure 3The support angle adjustment mechanism 7 includes a worm wheel 71 fixedly sleeved on the mounting shaft and a worm 72 rotatably mounted at the center of the base plate 5. The four sets of worm wheels 71 connected to the four sets of support rods 6 surround the worm 72 and mesh with the worm 72 at the same time. The rotation of the worm 72 controls the change of the angle between the multiple sets of support rods 6 and the base plate 5.

[0037] The rear end of the worm 72 passes through the central hole of the base plate 5 and forms a handle 73 at the tail end, which makes it convenient for the person holding it to rotate the worm 72. The cooperation between the worm 72 and the worm wheel 71 can not only adjust the position of the spring rod 62 according to the size of the poster, but also allow multiple sets of support rods 6 to be folded together when not in use to reduce the volume.

[0038] In one embodiment:

[0039] Please see Figure 2 , Figure 3 , Figure 4 On both the left and right sides of the base 5, there are protruding arms 51. The rear end of the protruding arms 51 is rotatably connected to the top of the stand 1. The base drives the protruding arms 51 to rotate on the stand 1 to change the display angle of the poster. Specifically:

[0040] Each set of protruding arms 51 is rotatably sleeved on an internally threaded sleeve 11 fixed on one side of the top of the stand 1. At the same time, the bolt head of the bolt 2 screwed into the internally threaded sleeve 11 presses down on the protruding arm 51. By tightening the bolt 2, the protruding arm 51 can be pressed and fixed, thereby fixing the posture of the base plate 5. The two sets of bolts 2 are facing each other and the bolt heads are close together. When changing the posture of the base plate 5, the two sets of bolts 2 must first be loosened to release the pressing and fixing of the protruding arm 51. Then the protruding arm 51 can be rotated to drive the base plate 5 to adjust its posture.

[0041] In one embodiment:

[0042] Please see Figure 3 , Figure 4 A socket 21 is provided at the head of the bolt 2. A sliding rod 3 slides linearly in the socket 21. At the same time, a handle 4 is connected between the outer ends of the two sets of sliding rods 3. The handle 4 is a U-shaped handle, with both ends fixed to the outer ends of the two sets of sliding rods 3 respectively. By holding the middle of the U-shaped handle and swinging it up and down, the two sets of bolts 2 can be rotated simultaneously to loosen or tighten at the same time.

[0043] The sliding rod 3 allows the bolt 2 to slide in the socket 21 to adapt to changes in the distance between the two bolts 2 when the bolt 2 is loosened or tightened.

[0044] During use, this solution requires daily maintenance of each component according to the established maintenance plan to ensure its working condition.
