Technical Field
[0001] The utility model relates to the technical field of furniture equipment, in particular to a foldable sound insulation door. Background Art
[0002] Soundproof doors are mainly used for sound insulation in places with high sound insulation requirements. The door panels are mainly made of new galvanized steel plates, and the interior uses professional sound insulation materials, damping sound insulation panels, sound insulation cotton, etc. as sound insulation fillers. They are usually suitable for large offices, entertainment venues, hospital operating rooms, recording studios, etc., and soundproof doors installed in some larger scenes need to be folded for easy transportation.
[0003] Some equipment on the market adopts a door body arrangement including a first door body and a second door body, and the first door body and the second door body are rotatably connected; a group of T-shaped slots are opened at one end of the first door body facing the second door body, and a T-shaped block is slidably arranged in the T-shaped slot, and a slot for inserting the T-shaped block is opened at one end of the second door body facing the first door body; when the T-shaped block is inserted into the slot, the T-shaped block is located in the slot and the T-shaped slot at the same time, so that the door body cannot rotate, and sliding the T-shaped block out of the slot can make the first door body and the second door body rotate relative to each other, thereby facilitating the transportation of the soundproof door.
[0004] However, in actual use of the above-mentioned device, the limiting T-shaped block may be worn after long-term use, causing the door to slide out of the slot when it is hit, causing the connection between the two door bodies to rotate, resulting in poor sound insulation effect; in view of this, we propose a foldable soundproof door. Utility Model Content
[0005] The purpose of the utility model is to provide a foldable soundproof door to solve the problems raised in the above background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a foldable soundproof door, comprising a left door, a connecting piece is fixedly connected to the front of the left door, a right door is arranged on one side of the connecting piece, a limiting structure is arranged on one side of the left door, the limiting structure comprises a placement groove, a placement groove is opened on one side of the left door, a through groove is opened on the front of the left door, a spring is fixedly connected to one side of the inner wall of the placement groove, a limiting groove is opened at the bottom of the through groove, one end of the spring is fixedly connected to a movable block, an annular groove is opened on the outer surface of the movable block, a movable part is sleeved inside the movable block, and a fixed groove is opened on one side of the right door.
[0007] Preferably, the fixing groove corresponds to the placement groove, and the size of the interior of the fixing groove matches the size of the movable block, so that the movable block can enter the interior of the fixing groove.
[0008] Preferably, the through slot and the limiting slot are communicated with the placement slot, and the through slot and the limiting slot are adapted to the movable member, which enables the movable member to move well inside the through slot and the limiting slot.
[0009] Preferably, the movable member is arranged inside the annular groove, and the size of the movable member is matched with the size of the annular groove, which allows the movable member to move inside the annular groove.
[0010] Preferably, an embedding groove is provided on one side of the left door, a small groove is provided on one side of the embedding groove, a long roller rod is provided on one side of the embedding groove, an embedding block is fixedly connected to one side of the right door, a large groove is provided on one side of the embedding block, an installation groove is provided on one side of the embedding block, a small spring is fixedly connected to one side of the inner wall of the installation groove, one end of the small spring is fixedly connected to a sliding block, and a small roller rod is rotatably connected to the bottom of the sliding block.
[0011] Preferably, the size of the long roller rod is matched with the size of the large groove, and the size of the small roller rod is matched with the size of the small groove, so that the small roller rod can be well inserted into the small groove.
[0012] Preferably, the size of the embedding block is matched with the size of the embedding groove, and rounded corners are provided on both sides of the inner walls of the large groove and the small groove, which can enable the long roller bar and the small roller bar to slide well into the large groove and the small groove.
[0013] Compared with the prior art, the utility model provides a foldable soundproof door, which has the following beneficial effects:
[0014] 1. In order to prevent the limit device from loosening during long-term use, the foldable soundproof door is configured to unfold the left door and the right door, and then move the movable part inside the limit groove to make the movable part slide out of the limit groove, so that the elastic force of the spring bounces the movable block into the fixed groove, and then the movable part is inserted into the limit groove. In this way, the left door and the right door can be well unfolded and are not prone to loosening, thereby achieving a better sound insulation effect.
[0015] 2. In order to achieve a better sealing effect at the connection between the door bodies, the foldable soundproof door allows the embedded block to enter the embedded groove when the left door and the right door are unfolded, wherein the small roller bar provided on one side of the embedded block contacts the long roller bar provided on one side of the embedded groove, which puts pressure on the small roller bar so that the slider compresses the small spring to contract, allowing the long roller bar to slide into the large groove. At the same time, the elastic force of the small spring causes the slider to push the small roller bar into the small groove, which makes it easier to unfold the left door and the right door when they are used, while also maintaining good sealing.
