Description

Technical Field

[0001] This invention relates to a detachable purification panel for cleanrooms. Background Technology

[0002] When assembling cleanroom panels, multiple panels need to be securely connected. Traditional methods for connecting panels often involve bolting, snap-fit ​​fastening, or simple adhesive bonding. However, bolting is cumbersome, and exposed bolts can lead to unevenness on the cleanroom surface; snap-fit ​​fastening is prone to loosening due to vibration during long-term use, resulting in insufficient connection strength; and adhesive bonding cannot achieve non-destructive assembly and disassembly.

[0003] Currently, some connection methods using pins and sockets have emerged in the market. However, existing pin connection structures often fail to ensure both secure locking and easy release, resulting in high time costs for cleanroom maintenance and replacement of purification panels. Therefore, corresponding technical solutions are needed to address these issues. Summary of the Invention

[0004] To overcome the aforementioned deficiencies of the prior art, the present invention provides a detachable purification panel for cleanrooms to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution of the present invention is to design a detachable purification panel for cleanrooms, comprising a first purification panel and a second purification panel arranged adjacent to each other. The first purification plate has a first connecting surface, on which a circular pin is provided. The outer wall of the circular pin is provided with a communicating axial groove and a circumferential groove, and the circumferential groove extends obliquely to the side away from the second purification plate. The second purification plate has a second connecting surface opposite to the first connecting surface. A rotating sleeve is rotatably mounted on the second connecting surface through a mounting hole. A torsion spring is provided between the rotating sleeve and the mounting hole. One end of the rotating sleeve has a insertion hole for inserting a circular pin, and the other end of the rotating sleeve has an operating hole. A locking pin is provided on the wall of the insertion hole. The side of the second purification plate has an operating port communicating with the operating hole, and the side of the second purification plate has a pin hole communicating with the mounting hole. A locking pin passes through the pin hole and abuts against the outer wall of the rotating sleeve. A radial protruding ring is provided on the outer wall of the locking pin. A sliding groove is provided on the wall of the pin hole to slide with the radial protruding ring. A compression spring is connected between the radial protruding ring and the end wall of the sliding groove. A locking hole for inserting the locking pin is provided on the outer wall of the rotating sleeve.

[0006] Preferably, the end of the locking pin away from the rotating sleeve is provided with a pull block.

[0007] Preferably, the side of the second purification plate is provided with a receiving groove for accommodating the pull block.

[0008] Preferably, the first connecting surface is provided with two sealing strips located on both sides of the circular pin.

[0009] Preferably, there are two circular pins on the first connecting surface, and the two circular pins are respectively located at both ends of the first connecting surface. There are two rotating sleeves on the second connecting surface, and the two rotating sleeves correspond one-to-one with the two circular pins.

[0010] Preferably, the operating hole is an internal hexagonal hole.

[0011] The advantages and beneficial effects of the present invention are as follows: It provides a detachable purification panel for cleanrooms, which has a reasonable structure, so that two adjacent purification panels can be tightly locked by the cooperation of a locking pin and an obliquely extending circumferential groove, and can be locked and reset and disassembled by the cooperation of a torsion spring, a locking pin and a compression spring. It has the advantages of compact structure, firm connection and convenient disassembly and assembly. Attached Figure Description

[0014] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0015] The specific technical solution of this invention is as follows: In one specific embodiment, such as Figure 1 and Figure 2 As shown, the present invention provides a detachable purification panel for cleanrooms, including a first purification panel 100 and a second purification panel 200 arranged adjacent to each other. The first purification plate 100 has a first connecting surface 101, on which a circular pin 102 is provided. The outer wall of the circular pin 102 is provided with a communicating axial groove 103 and a circumferential groove 104. The circumferential groove 104 extends obliquely along the side away from the second purification plate 200. The second purification plate 200 has a second connecting surface 201 opposite to the first connecting surface 101. A rotating sleeve 203 is rotatably mounted on the second connecting surface 201 through a mounting hole 202. A torsion spring 204 is provided between the rotating sleeve 203 and the mounting hole 202. One end of the rotating sleeve 203 has a insertion hole 205 for inserting a circular pin 102, and the other end of the rotating sleeve 203 has an operating hole 206. A retaining pin 207 is provided on the wall of the insertion hole 205. The side of the second purification plate 200 has a connection with the operating hole 206. The operation port 208 is connected to the second purification plate 200. The side of the second purification plate 200 is provided with a pin hole 209 that communicates with the mounting hole 202. A locking pin 210 that abuts against the outer wall of the rotating sleeve 203 is provided in the pin hole 209. A radial protruding ring 211 is provided on the outer wall of the locking pin 210. A sliding groove 212 that slides with the radial protruding ring 211 is provided on the hole wall of the pin hole 209. A compression spring 213 is connected between the end wall of the radial protruding ring 211 and the sliding groove 212. A locking hole for the locking pin 210 to be inserted is provided on the outer wall of the rotating sleeve 203.

[0016] Based on the above-mentioned approach, the working process and working principle of this invention are as follows.

[0017] Connection Process: When connecting the first purification plate 100 and the second purification plate 200, push the first purification plate 100 closer to the second purification plate 200. The circular pin 102 on the first purification plate 100 is aligned and inserted into the insertion hole 205 of the rotating sleeve 203. During insertion, the retaining pin 207 enters the axial groove 103 and slides inward along the axial groove 103. When the retaining pin 207 slides to the junction of the axial groove 103 and the circumferential groove 104, the first connecting surface 100 and the second connecting surface 201 are about to touch. Next, the operator inserts the operating tool 300 (such as an Allen wrench) into the operating port 208 and into the operating hole 206. Subsequently, the operating tool 300 is rotated, causing the rotating sleeve 203 to rotate in a predetermined direction. The rotating sleeve 203 drives the locking pin 207 on it to rotate synchronously, causing the locking pin 207 to slide from the axial groove 103 into the circumferential groove 104 and slide along the circumferential groove 104. Since the circumferential groove 104 extends obliquely away from the second purification plate 200, when the locking pin 207 slides along the oblique groove wall, the locking pin 207 abuts and presses against the groove wall of the circumferential groove 104. The obliquely extending groove wall converts the circumferential rotation of the locking pin 207 into axial thrust, thereby pulling the circular pin 102 in the opposite direction, causing the first purification plate 100 to move closer to the second purification plate 200, so that the first connecting surface 101 and the second connecting surface 201 are tightly fitted together, tightly pulling them together. At the same time, during the rotation of the rotating sleeve 203, the torsion spring 204 is torn and undergoes elastic deformation, accumulating elastic potential energy. When the rotating sleeve 203 rotates to the set angle and locks in place, the locking pin 210 will align with the locking hole on the rotating sleeve 203. At this time, under the elastic restoring force of the compression spring 213, the locking pin 210 moves along the slide groove 20212 toward the rotating sleeve 203, and its end inserts into the locking hole, thereby mechanically locking the rotating sleeve 203 in the current rotation position, preventing the rotating sleeve 203 from reversing, and ensuring a stable and tight connection between the first purification plate 100 and the second purification plate 200. After completion, the operator can remove the operating tool 300.

[0018] Disassembly process: When it is necessary to disassemble the first purification plate 100 and the second purification plate 200, the operator only needs to pull the locking pin 210 to move it away from the rotating sleeve 203. During this process, the radial convex ring 211 compresses the compression spring 213. When the locking pin 210 is completely pulled out of the locking hole, the rotating sleeve 203 loses its mechanical constraint. At this time, the torsion spring 204, which has undergone pre-elastic deformation, releases its elastic restoring force, automatically driving the rotating sleeve 203 to rotate in the opposite direction and return to its initial position. As the rotating sleeve 203 reverses and resets, the locking pin 207 will retract from the circumferential groove 104 into the axial groove 103. At this time, the first purification plate 100 is no longer under tension. The operator only needs to move the first purification plate 100 away from the second purification plate 200, so that the circular pin 102 slides out of the insertion hole 205, thus completing the quick disassembly and separation of the two purification plates.

[0019] In another specific embodiment, such as Figure 1 and Figure 2 As shown, the end of the locking pin 210 away from the rotating sleeve 203 is provided with a pull block 214.

[0020] By adopting the above solution, the operator can pull the locking pin 210 through the pull block 214, which helps to improve the operator's work efficiency.

[0021] In another specific embodiment, such as Figure 1 and Figure 2 As shown, the side of the second purification plate 200 is provided with a receiving groove 215 for accommodating the pull block 214.

[0022] The above solution allows the handle 214 to be fully embedded in the receiving groove 215, ensuring the flatness of the side surface of the second purification plate 200.

[0023] In another specific embodiment, such as Figure 1 As shown, the first connecting surface 101 is provided with two sealing strips 105 located on both sides of the circular pin 102.

[0024] By adopting the above solution, the sealing strip 105 can play a dual role: firstly, when the first purification plate 100 is pulled towards the second purification plate 200, the sealing strip 105 is deformed under pressure, which can effectively fill the splicing gap between the two plates and play an excellent role in isolation and sealing; secondly, the compressed sealing strip 105 itself can also provide a certain elastic reaction force to the connection, making the tension state more stable and further reducing the possibility of vibration and loosening.

[0025] In another specific embodiment, there are two circular pins 102 on the first connecting surface 101, and the two circular pins 102 are respectively located at both ends of the first connecting surface 101. There are two rotating sleeves 203 on the second connecting surface 200, and the two rotating sleeves 203 correspond one-to-one with the two circular pins 102.

[0026] The above solution is adopted: by setting corresponding circular pins 102 and rotating sleeves 203 at both ends of the first connecting surface 101 and the second connecting surface 201, the two large cleanroom panels can be locked together with multiple points of uniform force, which is beneficial to improving the overall structural strength after splicing.

[0027] In another specific embodiment, the operating hole 206 is an internal hexagonal hole.

[0028] The above solution allows a standard hex wrench to be directly engaged with the operating hole 206.

[0029] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
