Description

Technical Field

[0001] This utility model belongs to the field of folding display board technology, and in particular relates to a folding display board. Background Technology

[0002] Folding display panels are portable display devices characterized by their simple structure, ease of assembly, and portability. They are widely used in various exhibitions, commercial activities, and promotional events. Folding display panels refer to display panels whose components are combined by folding to form a retractable and foldable display structure. Folding display panels are small in size and lightweight, making them easy to carry and transport. Their simple structure allows for quick and convenient assembly, requiring no complex tools or professional personnel.

[0003] The problem with existing technology is that when existing folding display panels are unfolded for display, the unfolding angle is not supported and fixed, which may cause the frame to slip and rotate freely, resulting in an excessive unfolding angle and the problem of tipping over. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a folding display board that has the advantages of supporting and fixing the unfolding angle of the frame and being able to adjust the unfolding angle. This solves the problem that when existing folding display boards are unfolded for display, the unfolding angle is not supported and fixed, which may cause the frame to slip and rotate freely, resulting in an excessively large unfolding angle and tipping over.

[0005] This utility model is implemented as follows: a folding display board includes a frame, display boards, and pulleys. There are two frames, and the ends of the two frames that are close to each other are rotatably connected. There are two display boards, which are respectively disposed inside the two frames. There are four pulleys, which are evenly disposed on the left and right sides of the lower end of the two frames. A fixing and adjusting device is provided at the rear of the frame, and the left and right ends of the fixing and adjusting device are rotatably connected to the ends of the two frames that are far apart from each other.

[0006] The preferred fixing and adjusting device of this utility model includes a support component, an adjusting component, and a positioning component. The support component is disposed behind the two frames, the adjusting component is disposed inside the support component, and there are two positioning components, which are respectively disposed at the upper and lower ends inside the adjusting component. By setting up the fixing and adjusting device, the two frames are fixed, the angle of the two frames after unfolding is fixed, and the unfolding angle is adjusted to prevent the two frames from being unfixed and rotating at will during placement, which would cause the unfolding angle to be too large and cause the frame to tip over.

[0007] The preferred support assembly of this utility model includes a first support rod, a telescopic rod, and a second support rod. The first support rod is located at the left end of the frame and is rotatably connected to the frame. The telescopic rod is located inside the first support rod and extends out of the first support rod at its right end, and is slidably connected to the first support rod. The second support rod is located at the right end of the frame and is rotatably connected to the frame at its right end. The left end of the second support rod is rotatably connected to the end of the telescopic rod that extends out of the first support rod. By setting up the support assembly, the angle of the two frames when unfolded is supported, thereby maintaining the unfolding angle and preventing the frames from expanding arbitrarily.

[0008] As a preferred embodiment of this utility model, the upper surface of the support rod is provided with a plurality of adjustment grooves. The plurality of adjustment grooves are evenly arranged and all penetrate the support rod. By providing a plurality of adjustment grooves on the upper surface of the support rod, it is used to cooperate with the positioning component and to adjust the extension and retraction length of the telescopic rod.

[0009] The preferred adjustment component of this utility model includes a box and a tension spring. The box is disposed inside the left end of the support rod and is slidably connected to the support rod. The right side surface of the box is fixedly connected to the left end of the telescopic rod. The tension spring is disposed inside the upper end of the support rod and its left and right ends are fixedly connected to the right surface of the box and the left surface inside the support rod, respectively. By setting the adjustment component, the angle of the frame unfolding can be adjusted, thus providing support while adjusting the unfolding angle of the frame.

[0010] The preferred positioning component of this utility model includes a movable rod, a locking head, and a push spring. There are two movable rods, each disposed at one end inside the box. The upper and lower ends of the two movable rods are fixedly connected to the upper and lower surfaces of the inner end of the box, respectively. The locking head is sleeved on the surfaces of the two movable rods and slidably connected to them, with one end extending out of the box. There are also two push springs, each sleeved on the surfaces of the two movable rods. The upper and lower ends of the two push springs are fixedly connected to the inner surface of the box and the locking head, respectively. This positioning component, in conjunction with the adjustment groove, serves to fix the telescopic rod, providing a secure hold after adjustment to a suitable unfolding angle.

[0011] As a preferred embodiment of this utility model, the card head extending from the box body has chamfers on both the left and right sides. By having chamfers on the end of the card head extending from the box body, the card head can cooperate with the inner wall of the adjustment groove to squeeze and move when pressed down.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model solves the problem that when existing folding display panels are unfolded for display, the frame may not be fixed and may slide freely due to the lack of support and fixation at the unfolding angle, resulting in the frame being unable to be fixed and thus causing the unfolding angle to be too large and the panel to tip over. This is achieved by setting up a frame, display panel, pulley, fixing and adjusting device, support component, support rod one, telescopic rod, support rod two, adjusting component, box body, tension spring, positioning component, moving rod, locking head, push spring and adjusting groove in combination.

[0014] 2. This utility model uses a fixing and adjusting device to fix the two frames and the angle of the two frames after they are unfolded. It also has the function of adjusting the unfolding angle, so as to prevent the two frames from being unfixed and rotating at will when placed, which would cause the unfolding angle to be too large and cause them to tip over.

[0020] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0021] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1 to 4As shown, the present invention provides a folding display board, including a frame 1, a display board 2, and pulleys 3. There are two frames 1, which are rotatably connected to each other at their close ends. There are two display boards 2, which are respectively disposed inside the two frames 1. There are four pulleys 3, which are evenly disposed on the left and right sides of the lower end of the two frames 1. A fixing adjustment device 4 is provided at the rear of the frame 1, and the left and right ends of the fixing adjustment device 4 are rotatably connected to the ends of the two frames 1 that are far apart from each other.

[0023] refer to Figure 2 and Figure 3 The fixed adjustment device 4 includes a support component 41, an adjustment component 42, and a positioning component 43. The support component 41 is located behind the two frames 1. The adjustment component 42 is located inside the support component 41. There are two positioning components 43, which are respectively located at the upper and lower ends inside the adjustment component 42.

[0024] The above solution is adopted: by setting a fixing and adjusting device 4, the two frames 1 are fixed and the angle of the two frames 1 after unfolding is fixed. At the same time, the unfolding angle is adjusted to prevent the two frames 1 from being unfixed and rotating at will when placed, which would cause the unfolding angle to be too large and cause them to tip over.

[0025] refer to Figure 2 The support assembly 41 includes a first support rod 411, a telescopic rod 412, and a second support rod 413. The first support rod 411 is located at the left end of the frame 1 and is rotatably connected to the frame 1. The telescopic rod 412 is located inside the first support rod 411 and extends out of the first support rod 411 at its right end, and is slidably connected to the first support rod 411. The second support rod 413 is located at the right end of the frame 1 and is rotatably connected to the frame 1. The left end of the second support rod 413 is rotatably connected to the end of the telescopic rod 412 that extends out of the first support rod 411.

[0026] The above solution is adopted: by setting up a support component 41, the angle of the two frames 1 is supported, thereby maintaining the angle of the frames and preventing the frames 1 from expanding arbitrarily.

[0027] refer to Figure 2 and Figure 3 The upper surface of the support rod 411 has several adjustment grooves 5, which are evenly arranged and all pass through the support rod 411.

[0028] The above solution involves creating several adjustment grooves 5 on the upper surface of the support rod 411, which cooperate with the positioning component 43 and adjust the extension length of the telescopic rod 412.

[0029] refer to Figure 3The adjustment component 42 includes a housing 421 and a tension spring 422. The housing 421 is located inside the left end of the support rod 411 and is slidably connected to the support rod 411. The right side surface of the housing 421 is fixedly connected to the left end of the telescopic rod 412. The tension spring 422 is located inside the upper end of the support rod 411, and its left and right ends are fixedly connected to the right surface of the housing 421 and the left surface inside the support rod 411, respectively.

[0030] The above solution is adopted: by setting the adjustment component 42, the angle of the frame 1 can be adjusted, which has the function of adjusting the angle of the frame 1 while providing support.

[0031] refer to Figure 3 and Figure 4 The positioning component 43 includes a moving rod 431, a locking head 432, and a push spring 433. There are two moving rods 431, both of which are located inside one end of the box body 421. The upper and lower ends of the two moving rods 431 are fixedly connected to the upper and lower surfaces of the inner end of the box body 421, respectively. The locking head 432 is sleeved on the surface of the two moving rods 431 and is slidably connected to the two moving rods 431. One end of the locking head 432 extends out of the box body 421. There are two push springs 433, which are sleeved on the surface of the two moving rods 431, respectively. The upper and lower ends of the two push springs 433 are fixedly connected to the inner surface of the box body 421 and the locking head 432, respectively.

[0032] The above solution involves setting a positioning component 43 to cooperate with the adjustment groove 5 to fix the telescopic rod 412, thus fixing it after adjusting it to a suitable unfolding angle.

[0033] refer to Figure 4 The card head 432 extends out of the box body 421 and has chamfers on both the left and right sides.

[0034] The above solution is adopted: by opening a chamfer at one end of the card head 432 extending out of the box body 421, it can cooperate with the inner wall of the adjustment groove 5 to squeeze and move when the card head 432 is pressed down.

[0035] The working principle of this utility model:

[0036] In use, the two frames 1 are rotated open. Simultaneously, the ends of support rod 1 411 and support rod 2 413, which are far apart, rotate on the left and right sides of frame 1. At the same time, the ends of telescopic rod 412 and support rod 2 413, which are close together, are pulled and rotated open to parallel, thus limiting the unfolding angle. When adjusting the unfolding angle, the two locking heads 432 are pressed together, causing them to move inwards towards the box 421 on the surface of the moving rod 431. Simultaneously, the push spring 433 is compressed. After the locking heads 432 are pressed until the chamfered edge is fully inserted into the adjustment groove 5, the tension spring 433... 22. Pull the box 421 to the right, while simultaneously pressing the chamfer of the locking head 432 inside the adjusting groove 5, causing the locking head 432 to be pressed and moved into the box 421. As the box 421 moves to the right, it drives the telescopic rod 412 to move to the right within the support rod 1 411, while simultaneously pushing the support rod 2 413 to increase the unfolding angle of the frame 1. After adjusting to the appropriate position of the adjusting groove 5, the locking head 432 and the adjusting groove 5 are no longer pressed, and the push spring 433 will rebound to push the two locking heads 432 into the corresponding adjusting groove 5 to position the telescopic rod 412, thereby completing the adjustment.

[0037] In summary, this folding display panel, through the coordinated use of a frame 1, display panel 2, pulleys 3, fixing and adjusting device 4, support assembly 41, support rod one 4111, telescopic rod 412, support rod two 413, adjusting assembly 42, box body 421, tension spring 422, positioning assembly 43, moving rod 431, locking head 432, push spring 433, and adjusting groove 5, solves the problem that existing folding display panels, when unfolded for display, may cause the frame to slip and rotate freely due to the lack of support and fixation at the unfolding angle, resulting in an excessively large unfolding angle and tipping over.
