Abstract

This utility model relates to the field of cleanroom panel technology and discloses a splicable cleanroom panel. It achieves elastic self-locking during splicing by setting up slots, side grooves, locking slots, elastic locking tongues, and spring pieces. When the convex and concave grooves are molded together, the convex head first inserts into the concave shell, and the elastic locking tongue forms a reaction mold-closing with the convex head, causing the elastic locking tongue to also insert into the slot. The elastic locking tongue moves linearly laterally when entering the slot. When the elastic locking tongue touches the wedge-shaped inner wall formed between the side grooves, it is separated by the wedge-shaped inner wall and deforms, sliding into the side groove. As the elastic locking tongue moves into the side groove, the spring piece is pressed and squeezed by the inner wall of the side groove. When the elastic locking tongue continues to penetrate deeper into the side groove, causing the spring piece to reach the locking slot position, the spring piece is released from the squeezing restriction of the side groove and releases its elastic force, causing the spring piece to lock into the locking slot, thus achieving the effect of elastic self-locking.

Description

Technical Field

[0001] This utility model relates to the field of cleanroom panel technology, and in particular to a splicable cleanroom panel. Background Technology

[0002] Cleanroom panels, also known as purification panels, are composite panels made of materials such as color-coated steel sheets, stainless steel, and aluminum alloy sheets as the surface material. Cleanroom panels possess unique dustproof, antistatic, and antibacterial properties. They are widely used in cleanroom engineering fields with stringent indoor environmental requirements, such as electronics, pharmaceuticals, food, biology, aerospace, precision instrument manufacturing, and scientific research.

[0003] In existing technologies, traditional cleanroom panels achieve a snap-fit ​​effect through tongue and groove fitting. Since the cleanroom panels need to bear their own weight for a long time after splicing, they are prone to loosening due to fatigue. Especially in vibrating environments, the panels may sink, requiring complete disassembly for replacement, resulting in high maintenance costs. Furthermore, the tongue and groove joints require high-precision stacking, and gaps may appear due to misalignment during manual installation. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a modular purification panel with the advantages of self-locking and guiding positioning, thus solving the problems mentioned in the background.

[0005] This utility model provides the following technical solution: a splicable purification panel, including a splicing panel, the splicing panel including purification panel A and purification panel B, the splicing panel being spliced ​​from purification panel A and purification panel B, a sealing strip being provided between purification panel A and purification panel B, and protrusions and grooves being provided on both sides of purification panel A and purification panel B respectively, the protrusions and grooves being compatible.

[0006] Through the above structural design, the interplay between the convex groove and the recessed groove enables both elastic self-locking and precise positioning. When the convex groove of the purification plate B is inserted into the recessed groove of the purification plate A, the guide pin is inserted into the slot first. The guide pin is guided by the conical surface between the guide pin and the slot, which can accommodate any offset guide pin and forcibly guide the purification plate A and purification plate B to align, thus offsetting any slight offset during manual installation.

[0007] Preferably, the groove includes a protruding head and a female shell plate. The protruding head is located on one side of the purification plate A and the purification plate B. The female shell plate is located on the upper and lower sides of the protruding head. A female groove is formed on the side of the female shell plate near the protruding head. Guide pins are uniformly arranged in a linear array on the surface of the protruding head. The guide pins are generally conical. A slot is formed on one side of the protruding head. Lateral grooves are symmetrically formed inside the protruding head. A retaining groove is formed on one side of the lateral groove. The retaining groove is connected to the lateral groove and the slot.

[0008] With the above structural design, the convex groove allows the elastic locking tongue to deform elastically and penetrate into the side groove through the side groove and the locking groove, and the position of the spring piece is locked by the locking groove, so that the mold closing between the convex groove and the groove is mechanically self-locked.

[0009] Preferably, the groove includes a concave shell and a male shell piece. The concave shell is formed on the other side of the purification plate A and the purification plate B. The concave shell and the convex head are located symmetrically. The overall shape of the concave shell is adapted to the overall shape of the convex head. The male shell piece is located on the upper and lower sides of the convex head. The side of the male shell piece away from the concave shell is provided with male teeth. The shape and size of the male teeth are adapted to the female groove.

[0010] With the above structural design, after the male shell and female shell are molded together, the male tooth is inserted into the female groove to achieve an elastic snap-fit ​​effect, thus securing the positions of purification plate A and purification plate B.

[0011] Preferably, the inner wall of the concave shell is provided with guide holes in a linear and uniform manner. The guide holes are generally conical. The guide holes and guide pins are positioned correspondingly. The guide pins are matched in shape and size. The inner wall of the concave shell is symmetrically provided with elastic locking tongues. The elastic locking tongues are matched in shape and size with the slots. The end of the elastic locking tongues is made of elastic material.

[0012] With the above structural design, when the elastic locking tongue is located inside the lateral groove, the surface of the elastic locking tongue contacts and presses against the wedge-shaped inner wall. After it is in place, it locks the spring piece through the slot, forming a mechanical self-locking mechanism.

[0013] Preferably, after the groove and the groove are molded together, the end of the elastic locking tongue is located inside the side groove. The shape and size of the end of the elastic locking tongue are adapted to the side groove. The surface of the elastic locking tongue is provided with spring pieces in a linear array. The spring pieces are formed by bending stainless steel spring pieces. After the groove and the groove are molded together, the spring pieces are engaged with the slot.

[0014] With the above structural design, the spring is pressed and squeezed by the inner wall of the side groove. When the position of the elastic locking tongue continues to penetrate into the side groove and the spring reaches the slot position, the spring is released from the squeezing restriction of the side groove and the elastic force is released, so that the spring is stuck into the slot.

[0015] This utility model has the following advantages:

[0016] 1. This modular purification panel achieves elastic self-locking during connection through structural features such as slots, side grooves, locking slots, elastic locking tongues, and spring sheets. When the convex and concave grooves are molded together, the convex head first inserts into the concave shell, and the elastic locking tongue forms a reaction mold-closing with the convex head, causing the elastic locking tongue to also insert into the slot. The elastic locking tongue moves in a straight line when entering the slot. When the elastic locking tongue touches the wedge-shaped inner wall formed between the side grooves, it is separated by the wedge-shaped inner wall and deforms, sliding into the side groove. As the elastic locking tongue moves into the side groove, the spring sheet is pressed and squeezed by the inner wall of the side groove. When the elastic locking tongue continues to penetrate deeper into the side groove and the spring sheet reaches the locking slot position, the spring sheet is released from the squeezing restriction of the side groove and releases its elasticity, causing the spring sheet to lock into the locking slot, thus achieving the effect of elastic self-locking.

[0017] 2. This modular cleanroom panel achieves forced alignment during mold closing by incorporating a female shell, guide pins, male shell, and guide holes. Cleanroom panel A and cleanroom panel B are joined together via a convex groove and a concave groove. When the convex groove and concave groove are closed, the convex head first inserts into the concave shell, and the guide pin first inserts into the guide hole. The guide hole guides the precise alignment between the convex groove and the concave groove through a conical surface. The guide hole receives any offset guide pins and forces cleanroom panel A and cleanroom panel B to align, offsetting slight offsets during manual installation and achieving forced alignment during mold closing.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-2 A splicable cleanroom panel includes a splicing panel 1, which includes a cleanroom panel A11 and a cleanroom panel B12. The splicing panel 1 is formed by splicing cleanroom panels A11 and B12. In actual use, multiple cleanroom panels can be spliced ​​together. A sealing strip 13 is provided between cleanroom panels A11 and B12. The sides of cleanroom panels A11 and B12 are respectively provided with a protrusion 14 and a groove 15, which are adapted to each other.

[0027] In practical applications, this device achieves both elastic self-locking and precise positioning through the mutual cooperation between the protrusion 14 and the groove 15. When the purification plate A11 and purification plate B12 are spliced, the protrusion 14 of the purification plate B12 is inserted into the groove 15 of the purification plate A11. During insertion, the guide pin 24 first inserts into the slot 25. Guided by the conical surface between the guide pin 24 and the slot 25, the offset guide pin 24 can be received, forcibly guiding the purification plate A11 and purification plate B12 to align, offsetting slight offsets during manual installation. At the same time, the female shell plate 22 is pushed in from the outside of the male shell plate 32. Due to the lifting of the male shell plate 32, the female shell plate 22 undergoes slight deformation. When the positions of the female groove 23 and the male tooth 33 coincide, the male tooth 33 engages with the female groove 23, achieving an elastic locking effect. As pin 24 is inserted into slot 25, elastic locking tongue 35 simultaneously enters slot 25. Due to the wedge-shaped inner wall between the side grooves 26, the end of elastic locking tongue 35 is inserted into the side groove 26, and the spring piece 36 is compressed simultaneously, so that the spring piece 36 fits against the inner wall of the side groove 26 and together with the elastic locking tongue 35, it penetrates into the side groove 26. When the mold between the protrusion 14 and the groove 15 is in place, the spring piece 36 is located in the slot 27. Since the inner wall of the side groove 26 no longer applies pressure to the spring piece 36, the spring piece 36 deforms and springs up, locking into the slot 27, achieving the effect of elastic self-locking. When the purification plate A11 and purification plate B12 are separated due to the influence of the external environment, the spring piece 36 is locked into the slot 27, so that the purification plate A11 and purification plate B12 achieve a self-locking effect that becomes tighter with increasing tension.

[0028] Please see Figures 1-5The protrusion 14 includes a protrusion 21 and a female shell 22. The protrusion 21 is located on one side of the purification plate A11 and the purification plate B12. The female shell 22 is located on the upper and lower sides of the protrusion 21. A female groove 23 is opened on the side of the female shell 22 near the protrusion 21. Guide pins 24 are evenly arranged in a linear array on the surface of the protrusion 21. The guide pins 24 are generally conical. A slot 25 is opened on one side of the protrusion 21. Lateral grooves 26 are symmetrically opened inside the protrusion 21. A slot 27 is opened on one side of the lateral groove 26. The slot 27 is connected to the lateral groove 26 and the slot 25.

[0029] The protrusion 14 achieves a certain self-locking effect on the groove 15 through the female groove 23 and the locking groove 27. The protrusion 14 causes the elastic locking tongue 35 to undergo elastic deformation and penetrate into the side groove 26 through the side groove 26 and the locking groove 27, and locks the position of the spring piece 36 through the locking groove 27, so that the mold closing between the protrusion 14 and the groove 15 is mechanically self-locked, enhancing the stability of the connection.

[0030] Please see Figures 1-6 The groove 15 includes a concave shell 31 and a male shell plate 32. The concave shell 31 is opened on the other side of the purification plate A11 and the purification plate B12. The concave shell 31 and the protrusion 21 are located in symmetrical positions. The overall shape of the concave shell 31 is adapted to the overall shape of the protrusion 21. The male shell plate 32 is located on the upper and lower sides of the protrusion 21. The side of the male shell plate 32 away from the concave shell 31 is provided with a male tooth 33. The male tooth 33 and the female groove 23 are adapted to each other in shape and size.

[0031] After the male shell plate 32 and the female shell plate 22 are molded together, the male tooth 33 is inserted into the female groove 23 to achieve an elastic snap-fit ​​effect, which clamps the positions of the purification plate A11 and the purification plate B12, so that the purification plate A11 and the purification plate B12 have a preliminary self-locking effect after the mold is closed.

[0032] Please see Figures 1-6 The inner wall of the concave shell 31 is provided with guide holes 34 in a linear and uniform manner. The guide holes 34 are generally conical. The guide holes 34 and guide pins 24 are positioned correspondingly. The guide pins 24 are matched in shape and size. The inner wall of the concave shell 31 is provided with elastic locking tongues 35 symmetrically. The elastic locking tongues 35 are matched in shape and size with the slots 25. The end of the elastic locking tongues 35 is made of elastic material.

[0033] After the elastic locking tongue 35 enters the slot 25, it is separated by the wedge-shaped inner wall formed by the inner walls of the side groove 26, and enters the side groove 26 through elastic deformation. When the elastic locking tongue 35 is inside the side groove 26, the surface of the elastic locking tongue 35 contacts and is squeezed with the wedge-shaped inner wall. After it is in place, it locks the spring piece 36 through the slot 27, forming a mechanical self-locking.

[0034] Please see Figures 1-6After the protrusion 14 and the groove 15 are molded together, the end of the elastic locking tongue 35 is located inside the side groove 26. The shape and size of the end of the elastic locking tongue 35 are matched with those of the side groove 26. The surface of the elastic locking tongue 35 is provided with spring pieces 36 in a linear array. The spring pieces 36 are made of stainless steel spring pieces bent into shape. After the protrusion 14 and the groove 15 are molded together, the spring pieces 36 are engaged with the slot 27.

[0035] The spring piece 36 follows the elastic locking tongue 35 into the side groove 26. When it is squeezed by the inner wall of the side groove 26, the spring piece 36 is pressed and squeezed by the inner wall of the side groove 26. When the position of the elastic locking tongue 35 continues to go deeper into the side groove 26 and the spring piece 36 reaches the position of the slot 27, the spring piece 36 is released from the squeezing restriction of the side groove 26 and the elastic force is released, so that the spring piece 36 is locked into the slot 27, achieving the effect of elastic self-locking.

[0036] Working principle: In use, the purification plate A11 and purification plate B12 are joined together via the convex groove 14 and the recess 15. When the convex groove 14 and the recess 15 are closed, the protruding head 21 will first insert into the concave shell 31, and the elastic locking tongue 35 will form a reaction closing with the protruding head 21, so that the elastic locking tongue 35 will also insert into the slot 25. The guide pin 24 will first insert into the guide hole 34. The guide hole 34 guides the precise alignment between the convex groove 14 and the recess 15 through the conical surface. The guide hole 34 receives any offset. Guide pin 24 forces the alignment between purification plate A11 and purification plate B12, offsetting the slight offset during manual installation. At the same time, the female shell 22 is located outside the male shell 32 for mold closing operation. Due to the extrusion and lifting of the male shell 32, the female shell 22 is slightly offset and deformed upward. When the protrusion 14 and the groove 15 continue to close the mold, after the male tooth 33 is inserted into the female groove 23, the inner surface of the female shell 22 is in contact with the outer surface of the male shell 32, and the protrusion 14 and the groove 15 achieve an elastic snap-locking effect.

[0037] When the elastic locking tongue 35 enters the slot 25, it moves in a straight line. When the elastic locking tongue 35 touches the wedge-shaped inner wall formed between the side grooves 26, the elastic locking tongue 35 is separated by the wedge-shaped inner wall and deforms to slide into the side groove 26. When the elastic locking tongue 35 moves into the side groove 26, the spring piece 36 is pressed by the inner wall of the side groove 26 and squeezed. When the position of the elastic locking tongue 35 continues to penetrate into the side groove 26 and the spring piece 36 reaches the position of the slot 27, the spring piece 36 is released from the squeezing restriction of the side groove 26 and the elastic force is released, so that the spring piece 36 is locked into the slot 27, realizing the effect of elastic self-locking.
