Abstract
Description
Technical Field
[0001] This utility model relates to the field of building technology, and in particular to a cleanroom-use adhesive-free inner arc plate assembly. Background Technology
[0002] A cleanroom is a specially designed room that removes pollutants such as airborne particles, harmful air, and bacteria from a defined space and controls indoor temperature, cleanliness, indoor pressure, airflow speed and distribution, noise and vibration, lighting, and static electricity within a specific range.
[0003] In related technical solutions, the corners of cleanroom wall panels are connected using traditional arc-shaped transition structures. These arc-shaped transitions require a large amount of sealant at the contact points with the cleanroom panels. However, over time, the sealant, limited by the environment and its own quality, may peel off, leading to decreased sealing and contamination of the cleanroom. Utility Model Content
[0004] This invention provides a cleanroom-use, glue-free inner arc plate assembly, which can solve at least one of the above-mentioned technical problems.
[0005] To address the aforementioned technical problems, one or more embodiments of this utility model provide a cleanroom-use adhesive-free inner arc-shaped sheet assembly, comprising an interlocking base and an arc-shaped shielding sheet. The base includes two mutually perpendicular flat plates, which are respectively attached to two walls to be connected. The two plates are connected by an inclined plate, with the angle between the inclined plate and the flat plates being 45 degrees. A connecting rod is provided between the two flat plates, with one end connected to the inclined plate and the other end extending vertically away from the inclined plate. A hook is connected to the end of the connecting rod. The arc-shaped shielding sheet includes an arc-shaped sheet with a slot at its center along its own arc direction. The slot is located on the outer arc surface of the arc-shaped sheet, and the slot has an inner cavity extending through both ends along the axial direction of the arc-shaped sheet. The slot has an opening communicating with the inner cavity along the radial direction of the arc-shaped sheet towards the side away from the center of the arc-shaped sheet. The size of the opening is smaller than the size of the hook and the inner cavity. Extended pieces are provided on both sides of the opening, forming a flared opening to guide the insertion of the hook. Flexible soft rubber portions are fixed to both ends of the arc-shaped sheet along its own arc direction.
[0006] The beneficial effects of one or more of the above technical solutions are as follows:
[0007] Compared to existing technologies that use only arc-shaped pieces and adhesive bonding, this solution combines a base and an arc-shaped shielding piece. The flat plate of the base can be fixed to two wall panels by screws, and the screw connection position is covered by the arc-shaped shielding piece to achieve hidden screw fixing, without affecting the overall waterproofing of the inner arc-shaped piece assembly, and reducing the probability of rust at the screw connection position.
[0008] Furthermore, this solution facilitates physical structural pressure through the rebound of the arc-shaped sheet, and allows for the placement of flexible rubber sections at both ends of the arc-shaped sheet along its own arc direction. The tight contact between the rubber sections and the wall surface achieves a seal, thereby avoiding the use of sealant. Attached Figure Description

Detailed Implementation
[0014] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.
[0015] like Figures 1-4As shown, one or more embodiments of this utility model provide a cleanroom-use adhesive-free inner arc plate assembly, including a base 31 and an arc-shaped shielding plate 32 that are interlocked. The base 31 includes two mutually perpendicular flat plates 312, which are respectively attached to two walls to be connected. The two flat plates 312 are connected by an inclined plate 311, and the angle between the inclined plate 311 and the flat plate 312 is 45 degrees. A connecting rod 314 is provided between the two flat plates 312. One end of the connecting rod 314 is connected to the inclined plate 311, and the other end extends vertically away from the inclined plate 311. A hook 315 is connected to the end of the connecting rod 314. The arc-shaped shield 32 includes an arc-shaped piece 321. The arc-shaped piece 321 has a slot 322 at its center along its arc direction. The slot 322 is located on the outer arc surface of the arc-shaped piece 321. The slot 322 has an inner cavity 324 extending through both ends of the slot 322 along the axial direction of the arc-shaped piece 321. The slot 322 has an opening in the radial direction of the arc-shaped piece 321, facing away from the center of the arc-shaped piece 321, communicating with the inner cavity 324. The size of the opening is smaller than the size of the hook head 315 and the inner cavity 324. Extended pieces 323 are provided on both sides of the opening, forming a flared opening to guide the insertion of the hook head 315. Flexible soft rubber portions 325 are fixed to both ends of the arc-shaped piece 321 along its arc direction.
[0016] See Figure 1 The diagram shows an inner arc plate assembly 3 connected between two mutually perpendicular wall panels (i.e., the first wall panel 1 and the second wall panel 2 shown in the figure). It can be seen that the two mutually perpendicular flat plates 312 on the base 31 are respectively attached and fixed to the wall surfaces of the two wall panels, and at this time, there is a gap between the inclined plate 311 and the two wall surfaces at the included angle.
[0017] Specifically, the base 31 and the arc-shaped baffle 32 are two completely separate manufactured parts, connected only by the insertion of the hook 315 and the slot 322, thus facilitating the reuse of the entire inner arc-shaped piece assembly 3. The base 31 and the arc-shaped baffle 32 are both integrally molded structures, ensuring their structural strength. As a specific structural form, both the base 31 and the arc-shaped baffle 32 are injection-molded integral structures.
[0018] Specifically, the connecting rod 314 is a straight rod, and its extension direction is perpendicular to the surface direction of the inclined plate 311. One end of the connecting rod 314 is fixed to the inclined plate 311, and the other end extends away from the inclined plate 311. In the cross-section perpendicular to the extension direction of the connecting rod 314, the largest cross-sectional dimension of the hook head 315 is larger than the cross-sectional dimension of the connecting rod 314. Correspondingly, in this embodiment, the opening size of the slot portion 322 is smaller than the size of the hook head 315 when not under pressure. When the hook head 315 is aligned with the opening, pressing the arc-shaped piece 321 will cause the wedge-shaped surface of the hook head 315 to be squeezed to expand the opening, thereby allowing the hook head 315 to be fully inserted into the inner cavity 324 of the slot portion 322. After the hook head 315 is inserted into the inner cavity 324 of the slot portion 322, the opening position is reset, the end of the connecting rod 314 fills the opening position, and the opening position stops the end of the hook head 315 near the connecting rod 314 to prevent the hook head 315 from retracting.
[0019] In this embodiment, each of the two flat plates 312 is provided with a screw hole 313 for connecting to the wall panel, and the screw hole 313 is used for screws to pass through. Specifically, the screw hole 313 on the two flat plates 312 is the same length from the inclined plate 311, thereby ensuring that the two flat plates 312 are evenly stressed and fixed to the corresponding wall panel positions. The number of screw holes 313 on each flat plate 312 can be single or multiple, which can be set by those skilled in the art.
[0020] In this embodiment, the inclined plate 311 extends along a first direction to connect two flat plates 312 respectively, and the connecting rod 314 is located at the center of the inclined plate 311 along the first direction. Specifically, the central axis of the connecting rod 314 coincides with the center of the inclined plate 311 along the first direction.
[0021] In this embodiment, the outer circumferential surface of the connecting rod 314 has a threaded section. Specifically, when the outer circumference of the connecting rod 314 uses a threaded section, the thread protrusion can be used to limit the connecting rod 314 to the opening position. That is, the structure of the hook 315 prevents itself from retracting from the inner cavity 324 and the opening of the slot portion 322, and the presence of the thread prevents the connecting rod 314 from further inserting into the opening and the inner cavity 324, thereby achieving the positioning of the hook 315.
[0022] In this embodiment, the end of the hook head 315 away from the inclined plate 311 has two sides arranged in a wedge shape.
[0023] Specifically, the two sides are wedge-shaped surfaces, and the sharp corners formed by the two wedge-shaped surfaces extend in a direction away from the plate 312 and the connecting rod 314. The distance between the two wedge-shaped surfaces gradually increases in the direction close to the connecting rod 314 and connects with the connecting rod 314.
[0024] In this embodiment, the arc-shaped piece 321 is an elastic piece. Specifically, the arc-shaped piece 321 can be a plastic piece, or other materials can be used while meeting the elasticity requirements; this can be determined by those skilled in the art. The soft rubber part 325 can be made of rubber or silicone.
[0025] Working principle: When using this device, first fix the base 31 at the 90-degree inner corner formed by the two wall panels, so that the plate 312 is fixed to the wall panel by screws.
[0026] Then, align the hook 315 at the top of the connecting rod 314 with the opening on the arc-shaped baffle 32, and push the arc-shaped baffle forcefully onto the connecting rod 314, so that the hook 315 is squeezed into the inner cavity 324 of the slot 322 from the flared mouth and the opening in sequence. At this time, the two ends of the arc-shaped piece 321 along its own arc direction are pressed tightly against the wall surface of the wall panel, and the two ends of the arc-shaped piece 321 along its own arc direction respectively make close contact with the wall surface through the soft rubber part 325, achieving the effect of physical compression and flexible sealing.
[0027] The above specific embodiments should not be construed as limiting the scope of protection of this utility model. For those skilled in the art, any alternative improvements or modifications made to the embodiments of this utility model shall fall within the scope of protection of this utility model.
[0028] Any aspects of this utility model not described in detail are known to those skilled in the art.
