Description

Technical Field

[0001] This utility model belongs to the field of screen technology, specifically relating to a stable sound-absorbing screen. Background Technology

[0002] Screens are not only practical pieces of furniture but also carry rich cultural significance. In modern life, screens are used not only for home decoration but also widely in offices, restrooms, and other settings. Screens are primarily used to block wind, obstruct views, and divide spaces. To achieve sound insulation, sound-absorbing panels are now often used instead of traditional screen panels, providing a degree of soundproofing.

[0003] Currently, in order to facilitate the movement of screens, most screen designs include casters at the bottom. However, the small contact area between the casters and the ground significantly reduces the stability of the screen, making it prone to displacement when pushed by external forces.

[0004] Therefore, in order to address the aforementioned technical problems, it is necessary to provide a stable sound-absorbing screen.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a stable sound-absorbing screen that can solve the problem of low stability of existing screens.

[0007] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows:

[0008] A stable sound-absorbing screen includes: multiple screen frames, multiple support mechanisms, and locking components.

[0009] Each of the aforementioned screen frames is equipped with a sound-absorbing panel, and each pair of adjacent screen frames are rotatably connected.

[0010] Multiple support mechanisms are respectively installed at the bottom of each screen frame. Each support mechanism includes a stable base, a pair of casters, and a pair of control arms. The stable base rotates at the bottom of the screen frame, and widened feet are fixed to both ends of the stable base. The casters rotate on the widened feet. The control arms slide on the side walls of the stable base. A control head is fixed to the end of the stable base near the casters, and the control head is slidably connected to the casters. A rack is fixed to the end of each control arm away from the control head. A connecting shaft is fixed to the bottom of the sound-absorbing panel, and a gear is fixed to one end of the connecting shaft inside the stable base. The racks are located on both sides of the gear and mesh with it. A locking assembly is installed between the stable base and the sound-absorbing panel to lock them together.

[0011] In one embodiment of this utility model, a hinge is connected between each two adjacent screen frames, and the two adjacent screen frames are rotatably connected by the hinge.

[0012] In one embodiment of this utility model, a rotating shaft is fixed at the bottom of the screen frame, a rotating collar is fixed at the top of the stable base, the rotating collar rotates on the rotating shaft, the connecting shaft is fixed at the bottom of the rotating shaft, and the stable base rotates on the rotating shaft through the rotating collar, thereby realizing a rotating connection between the stable base and the screen frame.

[0013] In one embodiment of this utility model, the locking assembly includes a pair of slots and a rod. The pair of slots are respectively carved on both sides of the rotating shaft. The rod slides on the stable base, with one end near the rotating shaft inserted into the slot. By inserting the rod into the slot, the stable base is fixed to the screen frame, preventing rotation between the stable base and the screen frame.

[0014] In one embodiment of this utility model, the insertion rod is connected to a control board outside the stable base. The control board drives the insertion rod to move and pull the insertion rod out of the slot.

[0015] In one embodiment of this utility model, a spring is installed between the end of the insertion rod away from the rotation axis and the inner wall of the stable base, and the spring force is used to push the insertion rod into the slot.

[0016] In one embodiment of the present invention, a second sliding groove is provided on both sides of the stable base, and a pair of control arms slide in the second sliding groove respectively. The control arms slide in the stable base through the second sliding groove.

[0017] In one embodiment of this utility model, a pair of third sliding grooves are carved on the side walls near both ends of the stabilizing base, and a pair of sliders are fixed on the side walls of the control head. The pair of sliders slide in the third sliding grooves respectively. The control head slides in the third sliding grooves through the sliders, thereby achieving a sliding arrangement with the stabilizing base. When the caster wheel rotates out of the stabilizing base, the control head is positioned on top of the caster wheel and is positioned in the third sliding grooves through the sliders, thereby providing support for the caster wheel.

[0018] In one embodiment of this utility model, a sliding rod is fixed in the middle of the control head, and a control plate is fixed on the universal wheel. A first sliding groove is carved into the control plate, and the control head slides in the first sliding groove. The control head slides in the first sliding groove through the sliding rod, thereby realizing a sliding connection with the universal wheel. When the control head slides in the stable base and drives the universal wheel to rotate, the sliding rod also slides in the first sliding groove at the same time.

[0019] In one embodiment of this utility model, the bottom of the widened support leg is provided with an anti-slip layer to prevent slipping.

[0020] Compared with the prior art, the present invention provides a stable sound-absorbing screen, which, through relevant structural design, makes the sound-absorbing screen easy to move while effectively improving the stability of the screen. Attached Figure Description

Detailed Implementation

[0029] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0030] like Figure 1-5 As shown, a stable sound-absorbing screen in one embodiment of the present invention includes: multiple screen frames 1, multiple support mechanisms 2, and a locking assembly 206.

[0031] like Figure 1-5 As shown, sound-absorbing panels 101 are installed inside multiple screen frames 1, and each pair of adjacent screen frames 1 are rotatably connected. Multiple support mechanisms 2 are installed at the bottom of each screen frame 1. Each support mechanism 2 includes a stable base 201, a pair of casters 205, and a pair of control arms 207. The stable base 201 rotates at the bottom of the screen frame 1, and widened legs 204 are fixed to both ends of the bottom of the stable base 201. The pair of casters 205 rotate on the pair of widened legs 204. The pair of control arms 207 slide on the side walls of the stable base 201. A control head 210 is fixed to the end of the stable base 201 near the casters 205, and the control head 210 is slidably connected to the casters 205. A pair of control arms 207 each have a rack 209 fixed to the end furthest from the control head 210. A connecting shaft 221 is fixed to the bottom of the sound-absorbing plate 101, and a gear 208 is fixed to one end of the connecting shaft 221 inside the stabilizing base 201. A pair of racks 209 are respectively located on both sides of the gear 208 and mesh with each other. A locking assembly 206 is installed between the stabilizing base 201 and the sound-absorbing plate 101 to lock the stabilizing base 201 and the sound-absorbing plate 101 together.

[0032] Specifically, after moving the screen to the desired location, first unlock the screen frame 1 and the stable base 201 using the locking assembly 206. Then, slightly lift the screen frame 1 and rotate the stable base 201 180 degrees. During the rotation of the stable base 201, a pair of racks 209 rotate on the gear 208. Since the gear 208 is fixed to the bottom of the screen frame 1, when the stable base 201 rotates the racks 209, the gear 208 simultaneously causes the racks 209 to slide towards each other within the stable base 201. The racks 209 are then driven by the control arms 207 to slide the control heads 210 at both ends towards the gear 208. The control heads 210 drive the casters 205 to rotate into the stable base 201, causing the casters 205 to rotate into the stable base 201. After lowering the screen frame 1, the widened legs 204 can directly contact the ground to support the sound-absorbing panel 101. Then, the screen frame 1 and the stable base 201 are locked together by the locking assembly 206. Thus, when the screen frame 1 does not need to be moved, it is supported on the ground by the stable base 201, thereby improving the stability of the screen.

[0033] Additionally, when moving the screen to another location, first unlock the screen frame 1 and the stable base 201 using the locking assembly 206, then slightly lift the screen frame 1 and rotate the stable base 201 180 degrees in the opposite direction. This causes the control head 210 to rotate the caster wheel 205 out of the stable base 201, and then lock the screen frame 1 and the stable base 201 together using the locking assembly 206, thus bringing the caster wheel 205 into contact with the ground. The screen can then be moved. When the stable base 201 rotates 180 degrees, the control head 210 will either fully rotate the caster wheel 205 into or out of the stable base 201.

[0034] like Figure 1-3 As shown, a hinge 102 connects each pair of adjacent screen frames 1, allowing for rotatable connection between them. A rotating shaft 202 is fixed to the bottom of the screen frame 1, and a rotating collar 203 is fixed to the top of the stable base 201. The rotating collar 203 rotates on the rotating shaft 202, and a connecting shaft 221 is fixed to the bottom of the rotating shaft 202. The stable base 201 rotates on the rotating shaft 202 via the rotating collar 203, thus achieving a rotatable connection with the screen frame 1.

[0035] like Figure 2-4As shown, the locking assembly 206 includes a pair of slots 219 and a rod 217. The slots 219 are respectively carved into both sides of the rotating shaft 202. The rod 217 slides on the stabilizing base 201, with one end near the rotating shaft 202 inserted into the slot 219. By inserting the rod 217 into the slot 219, the stabilizing base 201 is fixed to the screen frame 1, preventing rotation between the stabilizing base 201 and the screen frame 1.

[0036] like Figure 2-4 As shown, the insertion rod 217 is located outside the stable base 201 and connected to a control plate 218. The control plate 218 drives the insertion rod 217 to move, pulling the insertion rod 217 out of the slot 219. A spring 220 is installed between the end of the insertion rod 217 away from the rotating shaft 202 and the inner wall of the stable base 201. The elastic force of the spring 220 is used to push the insertion rod 217 into the slot 219.

[0037] like Figure 4-5 As shown, the stabilizing base 201 has second sliding grooves 214 on both side walls. A pair of control arms 207 slide in the second sliding grooves 214, and the control arms 207 slide in the stabilizing base 201 through the second sliding grooves 214. A pair of third sliding grooves 216 are carved on the side walls near both ends of the stabilizing base 201. A pair of sliders 215 are fixed on both side walls of the control head 210, and the pair of sliders 215 slide in the pair of third sliding grooves 216. The control head 210 slides in the third sliding grooves 216 through the sliders 215, thus achieving a sliding arrangement with the stabilizing base 201. When the caster wheel 205 rotates out of the stabilizing base 201, the control head 210 is positioned on top of the caster wheel 205, and is positioned in the third sliding grooves 216 through the sliders 215, thus providing support for the caster wheel 205.

[0038] like Figure 4-5 As shown, a slide rod 213 is fixed in the middle of the control head 210, and a control plate 211 is fixed on the caster wheel 205. A first groove 212 is carved into the control plate 211, and the control head 210 slides within the first groove 212. The control head 210 slides within the first groove 212 via the slide rod 213, thus achieving a sliding connection with the caster wheel 205. When the control head 210 slides within the stable base 201, causing the caster wheel 205 to rotate, the slide rod 213 also slides simultaneously within the first groove 212. An anti-slip layer is provided at the bottom of the widened support leg 204 to prevent slippage.

[0039] The working principle is as follows: After the screen is moved to the desired location, the control board 218 first drives the insertion rod 217 to be pulled out of the slot 219, thereby unlocking the screen frame 1 and the stable base 201. Then, the screen frame 1 is slightly lifted and the stable base 201 is rotated 180 degrees. After the stable base 201 is rotated 180 degrees, the insertion rod 217 is aligned with the slot 219 on the other side of the rotating shaft 202. At this time, the elastic force of the spring 220 pushes the insertion rod 217, causing the insertion rod 217 to be inserted back into the slot 219, thus locking the screen frame 1 and the stable base 201.

[0040] During the rotation of the stabilizing base 201, a pair of racks 209 rotate on the gear 208. Since the gear 208 is fixed to the bottom of the screen frame 1, when the stabilizing base 201 rotates the racks 209, the gear 208 simultaneously causes the racks 209 to slide towards each other within the stabilizing base 201. The racks 209 are driven by the control arms 207 to slide the control heads 210 at both ends towards the gear 208. The control heads 210 slide in the first groove 212 via the slide rod 213, thereby causing the casters 205 to rotate into the stabilizing base 201. After the screen frame 1 is lowered, the widened legs 204 can directly contact the ground, supporting the sound-absorbing panel 101. Thus, when the screen frame 1 does not need to move, it is supported on the ground by the stabilizing base 201, thereby improving the stability of the screen.

[0041] When the screen needs to be moved to another location, first unlock the screen frame 1 and the stable base 201 using the locking assembly 206, then slightly lift the screen frame 1 and rotate the stable base 201 180 degrees in the opposite direction. This causes the control head 210 to rotate the caster wheel 205 out of the stable base 201, thereby making the caster wheel 205 contact the ground, and then the screen can be moved.

[0042] It will be apparent to those skilled in the art that this disclosure is not limited to the details of the exemplary embodiments described above, and that this disclosure can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of this disclosure is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this disclosure. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0043] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
