Description

Technical Field

[0001] This invention relates to the field of mechanical screen technology, specifically a multi-layer matrix mechanical screen. Background Technology

[0002] In order to accommodate people from multiple directions when using display screens, multi-layered mechanical screens are now often used to display information in multiple directions.

[0003] Chinese Patent Publication No. CN204348257U discloses a multi-layer multi-faceted rotating screen structure, which relates to the field of display screens. The structure includes a base on which a support shaft is vertically mounted, and multiple multi-faceted rotating screen structures are sleeved on the support shaft from bottom to top.

[0004] In this solution, when multiple screens are stacked together, a sufficiently long support axis is required, and all screens are mounted on the support axis. This is not convenient for different application scenarios. Depending on the number of screens to be stacked, support axes of different lengths are needed. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-layer matrix mechanical screen to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A multi-layer matrix mechanical screen includes a first frame and a second frame stacked together. A first screen is installed in the first frame, and a second screen is installed in the second frame. A base for maintaining balance is installed below the first frame. A rotation adjustment component for adjusting the relative angle between the first and second frames is connected between the first and second frames. The rotation adjustment component consists of a fixed seat fixedly connected to the upper end of the first frame and a rotating component assembled to the lower end of the second frame. The fixed seat and the rotating component are connected in a mating connection. The fixed seat has an assembly groove embedded in the end edge of the rotating component facing the rotating component. The rotating component has multiple sets of mounting holes. A rod is fixedly connected to the rotating component opposite to the assembly groove. The rod is adapted to the assembly groove. When the rod and the assembly groove are engaged, the axial relative rotation between the rotating component and the fixed seat is restricted. When the rod and the assembly groove are disengaged, the rotation restriction between the rotating component and the fixed seat is released.

[0008] As a further aspect of the present invention: the base includes a bracket, the bottom of the bracket is inlaid with a rubber pad layer, two sets of brackets are arranged parallel to each other on both sides of the lower end of the first frame, the upper end of the base is embedded with a groove, the lower end of the first frame is movably engaged in the groove, a connecting plate is fixedly connected between the two sets of brackets, and multiple threaded holes are provided through the lower end of the connecting plate.

[0009] As a further aspect of the present invention: the connecting plate and the groove are positioned opposite each other, the upper end of the connecting plate is flush with the bottom of the groove, and a reinforcing rib is installed between the side of the bracket and the lower end of the connecting plate.

[0010] As a further aspect of the present invention: the assembly groove includes an annular groove embedded at the edge of the end of the fixed seat with the axis of the fixed seat as the center. A plurality of blind holes are embedded in the annular groove. The blind holes are arranged in a circular array with the axis of the fixed seat as the origin. A separating wedge is fixedly connected in the annular groove between adjacent blind holes. The sides of the separating wedge facing the annular groove are all inclined surfaces. The insertion rod and the blind holes are correspondingly arranged.

[0011] As a further embodiment of the present invention: a sliding cylinder groove is embedded in the middle of the fixed base, and a baffle is provided at the upper opening edge of the sliding cylinder groove that tapers inward. The baffle and the sliding cylinder groove are concentrically arranged, and the diameter of the baffle is smaller than the diameter of the sliding cylinder groove. A cylinder is fixedly connected to the center of the end of the rotating member facing the fixed base. The cylinder and the baffle are slidably adapted. A sliding collar is fixedly connected to the periphery of the end of the cylinder that extends into the sliding cylinder groove. The sliding collar and the sliding cylinder groove are slidably adapted.

[0012] As a further aspect of the present invention: an elastic stop is movably embedded in the inner wall of the sliding cylinder groove. When the sliding collar moves from the bottom of the sliding cylinder groove to the side of the baffle and contacts the elastic stop, the elastic stop is squeezed into the inner wall of the sliding cylinder groove. When the sliding collar moves from the side of the baffle to the bottom of the sliding cylinder groove and contacts the elastic stop, the surface of the elastic stop and the surface of the sliding collar are movably attached.

[0013] As a further aspect of the present invention: the elastic stop block is rotatably connected to the inner wall of the sliding cylinder groove via a rotating shaft, the rotating shaft is disposed on the end of the elastic stop block away from the stop liner, and a torsion spring is connected between the rotating shaft and the sliding cylinder groove, the torsion spring causing the end of the elastic stop block away from the rotating shaft to rotate into the sliding cylinder groove.

[0014] As a further aspect of the present invention: the end of the elastic stop block near the stop liner is set as a plane, and the side of the elastic stop block facing the sliding cylinder groove is set as an arc-shaped surface.

[0015] As a further aspect of the present invention: symmetrical through-grooves are provided on both sides of the cylinder, the through-grooves are provided along the axial direction of the cylinder, and a sliding attachment is provided inside the cylinder in a sliding fit, the end of the sliding attachment away from the cylinder is slidably adapted to the inner wall of the sliding cylinder groove.

[0016] As a further aspect of the present invention: the sliding accessory includes a sliding pad that is slidably fitted in the sliding cylinder groove, a sliding column is fixedly connected to the center of the sliding pad, the sliding column is slidably fitted in the cylinder, and limit protrusions are symmetrically connected to both sides of the end of the sliding column away from the sliding pad, the limit protrusions and the strip groove are slidably adapted.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: In use, multiple first and second frames can be stacked sequentially as needed. The first frame can be stably placed by the base, while the second frame can be adjusted relative to the first frame by the cooperation between the rotating component and the fixed seat. In this way, the first and second screens on the first and second frames can face different directions, allowing them to face audiences from different directions during the display, which is convenient. The first and second frames can be stably placed. When adjusting, simply lift the second frame and the rotating component connected to its lower end upwards away from the fixed seat. At this time, the plug and the assembly slot can be disengaged. In this state, the rotating component and the assembly slot can be rotated relative to each other to adjust the relative angle of the first and second frames. After adjustment, the second frame is put down, and the plug on the rotating component falls and enters the assembly slot, thereby forming a limiting fit. The angle of the first and second frames can be fixed, the placement is stable, and the adjustment is very convenient. As needed, multiple layers can be stacked to accommodate displays from multiple directions. Attached Figure Description

Detailed Implementation

[0028] Please see Figures 1-7 In this embodiment of the invention, a multi-layer matrix mechanical screen includes a first frame 2 and a second frame 3 stacked together. A first screen 21 is installed in the first frame 2, and a second screen 31 is installed in the second frame 3. Multiple first frames 2 and second frames 3 can be stacked sequentially as needed. A base 1 for maintaining balance is installed below the first frame 2. A rotation adjustment component 4 for adjusting the relative angle between the second frame 3 and the first frame 2 is connected between the first frame 2 and the second frame 3. The rotation adjustment component 4 consists of a fixed base 41 fixedly connected to the upper end of the first frame 2 and a rotating component 4 assembled to the lower end of the second frame 3. The device consists of two components: a fixed base 41 and a rotating component 42, which are connected to each other. The fixed base 41 has an assembly groove 43 embedded in its end edge facing the rotating component 42. The rotating component 42 has multiple sets of mounting holes 4202. A plug rod 4201 is fixedly connected to the rotating component 42 at the position opposite to the assembly groove 43. The plug rod 4201 is adapted to the assembly groove 43. When the plug rod 4201 and the assembly groove 43 are engaged, the axial relative rotation of the rotating component 42 and the fixed base 41 is restricted. When the plug rod 4201 and the assembly groove 43 are disengaged, the rotation restriction between the rotating component 42 and the fixed base 41 is released.

[0029] In use, multiple first borders 2 and second borders 3 can be stacked sequentially as needed. The first border 2 is stably positioned via the base 1, while the second border 3, through the cooperation of the rotating component 42 and the fixed base 41, can adjust its relative tilt angle with the first border 2. This allows the first screen 21 and second screen 31 on the first border 2 and second border 3 to face different directions, facilitating presentations to audiences from different angles. Furthermore, the first border 2 and second border 3 are stably positioned; adjustments are only required by connecting the second border 3 to its lower end. When the rotating component 42 is lifted upwards and away from the fixed base 41, the insert rod 4201 and the assembly slot 43 can be disengaged. In this state, the rotating component 42 and the assembly slot 43 can be rotated relative to each other to adjust the relative angle of the first frame 2 and the second frame 3. After adjustment, the second frame 3 is lowered, and the insert rod 4201 on the rotating component 42 falls and enters the assembly slot 43, thus forming a limiting fit. The angle of the first frame 2 and the second frame 3 can be fixed, the placement is stable, and the adjustment is very convenient. As needed, multiple layers can be stacked to accommodate display in multiple directions.

[0030] The base 1 includes a bracket 11 with a rubber pad embedded in its bottom. Two sets of brackets 11 are arranged parallel to each other on both sides of the lower end of the first frame 2. A groove 12 is embedded in the upper end of the base 1, and the lower end of the first frame 2 is movably engaged in the groove 12. A connecting plate 13 is fixedly connected between the two sets of brackets 11. The connecting plate 13 and the groove 12 are positioned opposite each other, and the upper end of the connecting plate 13 is flush with the bottom of the groove 12. A reinforcing rib 14 is installed between the side of the bracket 11 and the lower end of the connecting plate 13. Different lengths of brackets 11 can be selected according to the number of stacked first frame 2 and second frame 3 to facilitate maintaining placement balance. The lower edge of the first frame 2 can be supported by the groove 12 and the connecting plate 13. The groove 12 can restrict and maintain the stability of the first frame 2. Multiple threaded holes can be provided through the lower end of the connecting plate 13 to facilitate the fixed assembly of the bottom of the first frame 2 and the connecting plate 13.

[0031] like Figures 4-7As shown, the assembly groove 43 includes an annular groove 4301 embedded at the end edge of the fixed base 41 with the axis of the fixed base 41 as the center. A plurality of blind holes 4303 are embedded in the annular groove 4301. The blind holes 4303 are arranged in a circular array with the axis of the fixed base 41 as the origin. A separating wedge 4302 is fixedly connected in the annular groove 4301 between adjacent blind holes 4303. The sides of the separating wedge 4302 facing the annular groove 4301 are all inclined. The insertion rod 4201 and the blind holes 4303 are correspondingly arranged. When the second frame 3 is stably positioned above the first frame 2, the insert rod 4201 is inserted into the blind hole 4303. This prevents the second frame 3 from rotating relative to the first frame 2. When angle adjustment is needed, the insert rod 4201 can be disengaged from the blind hole 4303 via the rotating component 42. When the end of the insert rod 4201 is no longer obstructed by the edge of the separating wedge 4302, the rotating component 42 and the fixed base 41 can be rotated relative to each other. After angle adjustment, the second frame 3 and the rotating component 42 are lowered. When the end of the insert rod 4201 contacts the side of the separating wedge 4302, it can be easily guided and inserted into the blind hole 4303, making the placement convenient and flexible.

[0032] The fixed base 41 has a sliding cylinder groove 44 embedded in its center. A retainer 45 is provided at the inwardly tapering edge of the upper opening of the sliding cylinder groove 44. The retainer 45 and the sliding cylinder groove 44 are concentrically arranged, and the diameter of the retainer 45 is smaller than the diameter of the sliding cylinder groove 44. A cylinder 4203 is fixedly connected to the center of the end of the rotating component 42 facing the fixed base 41. The cylinder 4203 and the retainer 45 are slidably fitted. A sliding collar 4204 is fixedly connected to the outer periphery of the end of the cylinder 4203 that extends into the sliding cylinder groove 44. The sliding collar 4204 is slidably fitted to the sliding cylinder groove 44. The rotating component 42 and the fixed base 41 can rotate relative to each other through the sliding fit of the cylinder 4203 and the retainer 45, and the sliding fit of the sliding collar 4204 and the sliding cylinder groove 44. This also prevents the cylinder 4203 from being excessively pulled out and falling off.

[0033] Furthermore, an elastic stop 46 is movably embedded in the inner wall of the sliding cylinder groove 44. When the sliding collar 4204 moves from the bottom of the sliding cylinder groove 44 toward the side of the retaining liner 45 and contacts the elastic stop 46, the elastic stop 46 is squeezed into the inner wall of the sliding cylinder groove 44. When the sliding collar 4204 moves from the side of the retaining liner 45 toward the bottom of the sliding cylinder groove 44 and contacts the elastic stop 46, the surface of the elastic stop 46 and the surface of the sliding collar 4204 are in movably fitted together, and the elastic stop 46 cannot be squeezed into the inner wall of the sliding cylinder groove 44. Normally, the sliding collar 4204 is located near the bottom of the sliding cylinder groove 44. When it is necessary to adjust the relative angle between the second frame 3 and the first frame 2, the second frame 3 and the rotating member 42 can be moved upward. When the cylinder 4203 on the rotating member 42 and the sliding collar 4204 move upward and pass the elastic stop 46, the elastic stop 46 is pressed against the inner wall of the sliding cylinder groove 44. After moving further away from the elastic stop 46, the elastic stop 46 pops out again. At this time, even if the second frame 3 and the rotating member 42 are put down, the elastic stop 46 can still cooperate to support the sliding collar 4204. This makes it safer and more convenient to rotate and adjust the angle. The elastic stop 46 is rotatably connected to the inner wall of the sliding cylinder groove 44 via a rotating shaft 4603. The rotating shaft 4603 is located at the end of the elastic stop 46 away from the retaining liner 45. A torsion spring connects the rotating shaft 4603 and the sliding cylinder groove 44. The torsion spring causes the end of the elastic stop 46 away from the rotating shaft 4603 to rotate into the sliding cylinder groove 44. Furthermore, the end of the elastic stop 46 near the retaining liner 45 is a flat surface 4602, and the side of the elastic stop 46 facing the inside of the sliding cylinder groove 44 is an arc-shaped surface 4601. When the sliding collar 4204 moves upward from the bottom of the sliding cylinder groove 44, it contacts the arc-shaped surface 4601 and, along the arc, squeezes and rotates the elastic stop 46, embedding it into the inner wall of the sliding cylinder groove 44. After passing the elastic stop 46, the elastic stop 46 returns to its original position under the action of the torsion spring, and the flat surface 4602 can be used to support the sliding collar 4204.

[0034] In the above solution, although flexible adjustments are possible, once the sliding collar 4204 moves close to the retaining liner 45, the elastic stop 46 pops out and is difficult to press back in. Therefore, if... Figures 4-9As shown, symmetrical through-grooves 4205 are provided on both sides of the cylinder 4203. The through-grooves 4205 extend along the axis of the cylinder 4203. A sliding attachment 47 is slidably fitted inside the cylinder 4203. The end of the sliding attachment 47 away from the cylinder 4203 is slidably adapted to the inner wall of the sliding cylinder groove 44. This arrangement allows for easy lowering of the second frame 3 and the rotating component 42 after angle adjustment. By moving the sliding attachment 47 upward, the end of the sliding attachment 47 away from the cylinder 4203 moves to fit against the lower surface of the sliding collar 4204. At this time, the end of the sliding attachment 47 away from the cylinder 4203 can press the elastic stop 46 into the inner wall of the sliding cylinder groove 44. Then, by moving the sliding attachment 47 and the sliding collar 4204 downward, the insertion rod 4201 can be aligned with the assembly groove 43 and inserted. This method is simple to use. When the sliding attachment 47 is not manually moved upward, it is located at the bottom of the sliding cylinder groove 44 and will not have any impact. In this solution, preferably, the distance between the elastic stop 46 and the stop liner 45 is less than the thickness difference between the end of the sliding attachment 47 and the sliding collar 4204, so that the end of the sliding attachment 47 and the sliding collar 4204 will not both pass through the elastic stop 46.

[0035] The sliding accessory 47 includes a sliding washer 4701 that slides within a sliding groove 44. A sliding post 4702 is fixedly connected to the center of the sliding washer 4701. The sliding post 4702 is slidably connected within the cylinder 4203. Limiting protrusions 4703 are symmetrically connected to both sides of the end of the sliding post 4702 away from the sliding washer 4701. The limiting protrusions 4703 and the strip groove 4205 are slidably adapted to each other. In use, the sliding post 4702 and the sliding washer 4701 can be moved upwards simply by using the limiting protrusions 4703. The operation is simple, the response speed is fast, and maintenance is convenient.
