[0033] In order to more clearly illustrate the overall concept of the utility model, the following will be described in detail with reference to the accompanying drawings.

[0034] Example 1

[0035] The utility model relates to a kind of clean door with exempt from to glue sealing strip, as Figures 1-2 It is used to connect between clean door and glass 14 side edge;Including sealing strip main body 1 and inner ring sealing baffle assembly and outer ring sealing baffle assembly;Sealing strip main body 1 is square box type structure, inner ring sealing baffle assembly is connected in the inner side perimeter of sealing strip main body 1, outer ring sealing baffle assembly is connected in the outer side perimeter of sealing strip main body 1;The top surface of inner ring sealing baffle assembly and outer ring sealing baffle assembly is connected to form the arc action surface 10 with inner recess, and the center distance of arc action surface 10 and glass 14 end face has gap no more than 0.8mm;Inner ring sealing baffle assembly includes first sealing baffle 2, second sealing baffle 3 and third sealing baffle 4;First sealing baffle 2 is arranged above second sealing baffle 3 along the height direction of the cross section of sealing strip main body 1, and second sealing baffle 3 is arranged above third sealing baffle 4 along the height direction of the cross section of sealing strip main body 1.

[0036] As Figure 1 And Figure 2As shown, the entire clean door with the glue-free sealing strip 12 is in a square frame structure, which is to be able to be sleeved outside the glass 14, to realize the connection between the side edge of the glass 14 and the clean door. Specifically, in the embodiment 2, it can be known from the description of the components of the clean door that the clean door includes the clean door body 11 and the limiting profile 13, and the limiting profile 13 is filled in the clean door body 11. The limiting profile 13 can reserve a position for the glass 14. The glue-free sealing strip 12 is more precisely connected between the limiting profile 13 and the side edge of the glass 14. The sealing strip 12 includes a sealing strip body 1, an inner ring sealing stop component arranged in the inner ring of the sealing strip body 1, and an outer ring sealing stop component arranged in the outer ring of the sealing strip body 1. The inner ring sealing stop component is directly connected with the side edge of the glass 14, and the outer ring sealing stop component is directly connected with the limiting profile 13. By arranging the sealing strip 12, the traditional glueing between the clean door and the glass 14 to install the glass 14 can be avoided. The glue body is prone to cracking, deformation and other problems during long-term use. The solidification time of the glue is greatly affected by the external environment such as temperature. The solidification time is multiplied when the room temperature is below 20℃. After solidification, the surface shrinks seriously, which causes the clean door, the glass 14 and the glue body to be not in line, which is prone to dust accumulation, and does not meet the use requirements of the clean door. In the present application, when the glass 14 is installed on the clean door, the sealing strip 12 is inserted between the clean door and the side edge of the glass 14 to realize the installation of the glass 14, thereby avoiding the gluing process. Moreover, the inner ring sealing stop component is connected to the inner side of the sealing strip body 1, and the outer ring sealing stop component is connected to the outer side of the sealing strip body 1, which can quickly realize the installation between the side edge of the glass 14 and the clean door, which is convenient, time-saving and labor-saving, and facilitates disassembly and assembly.

[0037] In addition, the inner ring sealing stop component includes a first sealing stop 2, a second sealing stop 3 and a third sealing stop 4. The first sealing stop 2 is arranged above the second sealing stop 3 along the height direction of the cross section of the sealing strip body 1. The second sealing stop 3 is arranged above the third sealing stop 4 along the height direction of the cross section of the sealing strip body 1. The multiple sealing stops can further enhance the connection strength between the clean door and the glass 14. Moreover, the entire sealing strip 12 has elasticity, which can realize adaptive connection to different gaps between the clean door and the glass 14, that is, has good gap error adaptation capability, and can meet the sealing and dust accumulation effect for different gaps.

[0038] Moreover, the top surfaces of the inner ring sealing stop component and the outer ring sealing stop component are connected to form a concave circular arc acting surface 10. The center of the circular arc acting surface 10 is spaced apart from the end surface of the glass 14 by a gap of not more than 0.8 mm, which achieves a smooth transition effect between the clean door and the glass 14.

[0039] In a preferred embodiment, the outer ring sealing edge assembly includes a first sealing edge 5, a second sealing edge 6, and a third sealing edge 7; the first sealing edge 5 and the first sealing edge 2 are symmetrically arranged on both sides of the sealing strip body 1, the second sealing edge 6 and the second sealing edge 3 are symmetrically arranged on both sides of the sealing strip body 1, and the third sealing edge 7 and the third sealing edge 4 are symmetrically arranged on both sides of the sealing strip body 1.

[0040] like Figure 2 As shown, the outer ring sealing edge assembly and the inner ring sealing edge assembly are symmetrically arranged on the left and right sides of the sealing strip body 1. From top to bottom on the left side, the first sealing edge 5, the second sealing edge 6, the sealing wing 9 and the third sealing edge 7 are arranged in sequence. The first sealing edge 5 is symmetrically arranged with the first sealing edge 2 on the right side, the second sealing edge 6 is symmetrically arranged with the second sealing edge 3 on the right side, the sealing wing 9 is symmetrically arranged with the sealing wing 8 on the right side, and the third sealing edge 7 is symmetrically arranged with the third sealing edge 4 on the right side.

[0041] The first sealing edge 5 is symmetrically arranged with the first sealing edge 2 and has the same structure; the second sealing edge 6 is symmetrically arranged with the second sealing edge 3 and has the same structure; the third sealing edge 7 is symmetrically arranged with the third sealing edge 4 and has the same structure; and the sealing wing 9 is symmetrically arranged with the sealing wing 8 and has the same structure. Therefore, this application takes the inner ring sealing edge assembly as an example for detailed description:

[0042] In a preferred embodiment, the first sealing edge 2 has a tapered cross-section, and the size of the first sealing edge 2 gradually decreases from the side facing the sealing strip body 1 to the side facing outward.

[0043] like Figure 2 As shown, along the cross-section of the sealing strip 12, the sealing strip body 1 is in the middle. The sealing strip body 1 has a square structure. The top right side of the sealing strip body 1 is connected to the first sealing flange 2. It can be seen that the cross-section of the first sealing flange 2 has a conical structure. Figure 2As shown in the orientation, the left side of the first sealing baffle 2 is connected with the sealing strip body 1, the right end of the first sealing baffle 2 is outward, and the right end of the first sealing baffle 2 is used to connect with the side edge of the glass 14; the size of the first sealing baffle 2 from the left end to the right end in the height direction of the sealing strip body 1 gradually decreases; the first sealing baffle 2 is arranged in a narrow structure, so as to better adapt to the gap error, so that different gaps can meet and dust accumulation is not easy to achieve; and the top surface of the first sealing baffle 2 is in a circular arc structure, the top surface of the first sealing baffle 2 and the top surface of the first closed baffle 5 on the left side are connected to form an inwardly recessed circular arc action surface 10, when the sealing strip 12 is pressed into the gap between the clean door and the glass 14, there is a gap of not more than 0.8 mm between the circular arc action surface 10 and the end surface of the glass 14, to achieve the effect of smooth transition between the clean door and the glass 14.

[0044] Further, the top surface of the first sealing baffle 2 and the first closed baffle 5 is higher than the top surface of the sealing strip body 1 and can be connected to form an inwardly recessed circular arc action surface 10.

[0045] The top surface of the first sealing baffle 2 and the first closed baffle 5 is connected to form a complete surface, so the height of the top surface of the first sealing baffle 2 and the first closed baffle 5 is higher than the height of the top surface of the sealing strip body 1, so that the top surface of the first sealing baffle 2 and the first closed baffle 5 is connected as a whole and is higher than the top surface of the sealing strip body 1, forming an inwardly recessed circular arc action surface 10, which is convenient for pressing in the sealing strip 12, and the lowest position of the circular arc action surface 10 has a gap of not more than 0.8 mm with the end surface of the glass 14, achieving the effect of smooth transition.

[0046] As a preferred embodiment, the cross section of the second sealing baffle 3 is in a long strip structure, and the outward end of the second sealing baffle 3 has a circular chamfer.

[0047] The purpose of setting the circular chamfer of the second sealing baffle 3 is that the second sealing baffle 3 can move more smoothly with the side edge of the glass 14 during the pressing process, which is beneficial for rapid assembly.

[0048] As a preferred embodiment, the glue-free sealing strip 12 for clean door further comprises a sealing fin 8, which is arranged between the second sealing baffle 3 and the third sealing baffle 4, and the structure and size of the sealing fin 8 are the same as those of the second sealing baffle 3.

[0049] The sealing fin 8 corresponds to another separate second sealing baffle 3, so as to increase the number of the second sealing baffles 3, so as to increase the sealing effect between the first sealing baffle 2 and the third sealing baffle 4.

[0050] Furthermore, along the width direction of the cross-section of the sealing strip body 1, the dimensions of the sealing wing 8 and the second sealing stop 3 are both smaller than the dimensions of the first sealing stop 2; the dimensions of the sealing wing 8 and the second sealing stop 3 along the width direction of the cross-section of the sealing strip body 1 are greater than the distance between the sealing wing 8 and the second sealing stop 3 along the height direction of the cross-section of the sealing strip body 1.

[0051] like Figure 2 The diagram shows a cross-sectional view of the sealing strip 12. Located in the center of the diagram, perpendicular to the height of the sealing strip body 1 (i.e., the width of the sealing strip body 1), the length of the sealing wing 8 and the length of the second sealing baffle 3 are less than the length of the first sealing baffle 2. The length of the sealing wing 8 is greater than the distance between the sealing wing 8 and the second sealing baffle 3 along the height of the cross-section of the sealing strip body 1, and the length of the second sealing baffle 3 is greater than the distance between the sealing wing 8 and the second sealing baffle 3 along the height of the cross-section of the sealing strip body 1.

[0052] Moreover, the dimensions of the sealing wing 8 and the second sealing stop 3 along the width direction of the cross-section of the sealing strip body 1 are greater than the distance between the sealing wing 8 and the second sealing stop 3 along the height direction of the cross-section of the sealing strip body 1. This allows the sealing strip 12 to achieve an interference fit in different gaps, thus achieving a double seal that is not prone to air or water leakage.

[0053] Furthermore, the dimension of the third sealing edge 4 along the width direction of the cross-section of the sealing strip body 1 is greater than the dimension of the sealing wing 8 and the second sealing edge 3 along the width direction of the cross-section of the sealing strip body 1.

[0054] like Figure 2 As shown, along the width direction of the sealing strip body 1, the width of the third sealing edge 4 is greater than the width of the sealing wing 8, and the width of the third sealing edge 4 is greater than the width of the second sealing edge 3. This results in an extended and elastic third sealing edge 4 at the bottom of the sealing strip 12, which is less likely to fall off after being inserted into the gap and subjected to long-term vibration. This enhances the tightness of the connection between the entire sealing strip 12 and the side of the glass 14. Moreover, the longer length of the third sealing edge 4 can reduce the phenomenon of light transmission caused by incomplete black silkscreen printing due to excessive chamfering of the glass 14, thereby further enhancing the sealing effect.

[0055] Preferably, the distance between the first sealing edge 2 and the second sealing edge 3, and the distance between the second sealing edge 3 and the third sealing edge 4 are the same.

[0056] The sealing strip 12 of this application features a symmetrical design, eliminating the need to distinguish between the front and back during manufacturing and use. Furthermore, this sealing strip 12 employs a composite design, with a hard rubber center and a soft rubber outer layer, achieving the necessary hardness for pressing into gaps while also providing good elasticity on the outer side.

[0057] Example 2

[0058] This application also relates to a cleanroom door, such as Figure 3 As shown, the device includes a cleanroom door sealant strip that does not require glue, a cleanroom door body 11, a limiting profile 13, and a glass 14. The cleanroom door body 11 is provided with a glass 14 inside, and a limiting profile 13 is provided between the outer side of the glass 14 and the inner wall of the cleanroom door body 11. A sealant strip is connected between the limiting profile 13 and the side of the glass 14.

[0059] After the cleanroom door body 11 is manufactured, the limiting profile 13 on the outside of the glass 14 is placed inside, double-sided tape is applied, and then the glass 14, which is made of tempered glass, is placed inside. Finally, the sealing strip 12 is pressed in using a rubber pressure roller. The sealing strip 12 in this application is made of thermoplastic elastomer TPE.
