Description

Technical Field

[0001] This utility model belongs to the field of cleanroom technology, and more specifically, it relates to a guide rail bracket for a cleanroom pass-through window. Background Technology

[0002] A cleanroom is a specially designed room that eliminates airborne particles, harmful gases, bacteria, and other contaminants within a defined space, and controls the temperature, humidity, cleanliness, pressure, airflow speed and distribution, noise and vibration, lighting, and static electricity within a specific range. Regardless of changes in external air conditions, a cleanroom can maintain the originally set requirements for cleanliness, temperature, humidity, and pressure.

[0003] The main purpose of cleanrooms is to control particulate and microbial contamination to ensure product quality during the production process. Cleanrooms play a crucial role, especially in fields such as semiconductor manufacturing, biomedicine, precision machinery, and the food industry.

[0004] Currently, items are typically transferred into cleanrooms via windows, and sliding windows are a common type of window used in cleanrooms. However, this type of sliding window, such as... Figure 1 As shown, it includes window a and guide rail bracket b. After window a is installed, there is often a gap between the upper end of window a and guide rail bracket b, so that window a can be lifted up to realize the installation or removal of window a. This results in relatively weak sealing when closed, which can easily cause cleanroom contamination. Utility Model Content

Detailed Implementation

[0032] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] It should be noted that all directional indicators (such as up, down, left, right, front, back, upper end, lower end, top, bottom, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0034] See Figure 2 As shown, a guide rail bracket for a cleanroom pass-through window includes a square frame 1 for mounting the window and a sealing mechanism 2. The square frame 1 includes an upper guide rail 11, a lower guide rail 12, and connecting rods 13 disposed at the left and right ends of the upper guide rail 11 and the lower guide rail 12. The sealing mechanism 2 is disposed inside the upper guide rail 11, and the sealing mechanism 2 can press down the window in the closed state while sealing the gap between the window and the upper guide rail 11.

[0035] Furthermore, in this embodiment, see Figure 3 As shown, the sealing mechanism 2 consists of a fixed window sealing assembly 21 and a movable window sealing assembly 22.

[0036] Further, see Figure 4As shown, in this embodiment, the fixed window sealing assembly 21 includes a limiting bolt 211 that is vertically inserted into the upper guide rail 11 and can slide in the upper guide rail 11. A first connecting plate 212 is provided at the lower end of the limiting bolt 211. A first spring 213 is sleeved on the limiting bolt 211 between the first connecting plate 212 and the upper guide rail 11. Under the action of no external force, the first spring 213 has a tendency to drive the first connecting plate 212 to move downward. A first sealing gasket 214 is provided on the lower end surface of the first connecting plate 212.

[0037] Further, see Figure 5 and Figure 7 As shown, in this embodiment, the movable window sealing assembly 22 includes a second connecting plate 221, and a second sealing gasket 222 is provided on the lower end surface of the second connecting plate 221; a guide shaft 223 is provided on the upper end surface of the second connecting plate 221, which passes through the upper guide rail 11 and can slide in the upper guide rail 11; a connecting block 224 is provided on the upper end of the guide shaft 223; a second spring 225 is sleeved on the guide shaft 223 between the connecting block 224 and the upper guide rail 11; under no external force, the second spring 225 has a tendency to drive the connecting block 224 to move upward; a pressing module 226 is provided on the connecting block 224, which can press down the connecting block 224.

[0038] Furthermore, in this embodiment, see... Figure 6 As shown, the pressing module 226 includes a pressing block 2261 whose bottom surface contacts the upper surface of the connecting block 224. The pressing block 2261 is mounted on a support base 2263 and can move left and right via a linear guide rail 2262. A fixing block 2264 is provided at the left end of the pressing block 2261, and a third spring 2265 is provided on the surface of the fixing block 2264 opposite to the pressing block 2261. A lever 2266 is provided at the right end of the pressing block 2261, and the lever 2266 is hinged to a hinge seat 2267. During installation, the support base 2263 and the fixing block 2264 are fixed to the upper guide rail. At the upper end of 11, the hinge seat 2267 is fixed to the side wall of the connecting rod 13 on the right side. The lever 2266 should satisfy the following condition: as the lever 2266 rotates counterclockwise, its upper end can drive the lower pressure block 2261 to move to the left. At this time, as the lower pressure block 2261 moves to the left, the third spring 2265 is compressed. Therefore, when the lever 2266 releases the driving force on the lower pressure block 2261 to move to the left, under the rebound force of the third spring 2265, the lower pressure block 2261 moves to the right and drives the lever 2266 to rotate clockwise. In this embodiment, see... Figure 7As shown, a through hole is provided on the connecting rod 13 on the right side. As the lever 2266 rotates clockwise, the lower end of the lever 2266 can extend into the square frame 1 through the through hole, so that when the window is closed, the lever 2266 can be driven to rotate counterclockwise by squeezing.

[0039] In this embodiment, to enable the pressing block 2261 to move to the left, driving the connecting block 224 to move downwards, and to move to the right, releasing the pressure on the connecting block 224, the contact surface between the pressing block 2261 and the connecting block 224 is an inclined surface, with the inclination direction as follows: Figure 7 As shown.

[0040] Further, see Figure 8 As shown, in this embodiment, the guide shaft 223 is a stepped shaft, which includes a first stepped segment 2231 and a second stepped segment 2232. The outer diameter of the second stepped segment 2232 is smaller than the outer diameter of the first stepped segment 2231, and an external thread is tapped on the second stepped segment 2232. The connecting block 224 has stepped holes corresponding to the guide shaft 223. The stepped holes include a first hole segment 2241 and a second hole segment 2242. The diameter of the second hole segment 2242 is larger than that of the first hole segment 2241, and the diameter of the first hole segment 2241 is larger than the outer diameter of the second stepped segment 2232, but smaller than the outer diameter of the first stepped segment 2231. During connection, the second stepped segment 2232 extends into the second hole segment 2242 through the first hole segment 2241, and a nut is locked to connect the guide shaft 223 and the connecting block 224 together.

[0041] Further, see Figure 2 As shown, in this embodiment, a limiting block 3 is provided inside the lower guide rail 12, and a limiting hole 121 is opened inside the lower guide rail 12.

[0042] The working principle of this utility model is as follows:

[0043] See Figures 9-11 As shown in the figure (label A represents the fixed window; label B represents the movable window; label C represents the latch; label D represents the guide rail bracket), during installation, first place the fixed window into the upper guide rail 11, then lift it upwards. At this time, the first connecting plate 212 moves upwards under force, further compressing the first spring 213. After the lower end of the fixed window can be placed into the lower guide rail 12, stop lifting upwards and place the fixed window into the lower guide rail 12. Then release the fixed window. At this time, under the rebound force of the first spring 213, drive the first connecting plate 212 to move downwards, so that the first sealing gasket 214 fits tightly with the upper end of the fixed window, achieving a seal. Then install the upper limit block 3 to restrict the fixed window within the square frame 1, as shown.Figure 10 As shown, at this time, ensure that the side wall of the fixed window is tightly fitted with the left connecting rod 13; then, after installing the pin on the side wall of the movable window, place the upper end of the movable window into the upper guide rail 11 and lift it upwards to place the movable window into the lower guide rail 12, and then release the movable window.

[0044] When closing the active window, push it to the right. As the active window approaches closing, it presses against the lower end of the lever 2266 inserted into the square frame 1, causing the lever 2266 to rotate counterclockwise. This drives the upper end of the lever 2266 to move the lower pressure block 2261 to the left, compressing the third spring 2265. Simultaneously, the lower pressure connecting block 224 moves downward. When the active window is fully closed, the connecting block 224 moves to its lowest point, further compressing the second spring 225. The second sealing gasket 222 then fits tightly against the upper end of the active window, achieving a seal. Finally, insert the pin into the limiting hole 121. Figure 11 As shown.

[0045] When the movable window needs to be opened, the pin is pulled out from the limiting hole 121, and the movable window is pushed to the right. As the movable window moves to the left, the rebound force of the third spring 2265 drives the lower pressure block 2261 to move to the right, and the push lever 2266 rotates clockwise until the lower end of the lever 2266 abuts against the through hole on the square frame 1. At this time, the lower front end of the lever 2266 re-extends into the square frame 1. As the lower pressure block 2261 moves to the right, the connecting block 224 moves upward under the rebound force of the second spring 225, away from the upper end of the movable window, and releases its contact with the upper end of the movable window, thereby relieving the resistance to the movement of the movable window caused by the contact.

[0046] Finally, it should be noted that in actual use, to avoid gaps between adjacent sides of the two windows after they are closed, sealing strips should be affixed to the adjacent sides of the two windows. The sealing strips should not affect the opening and closing of the movable windows, but should maintain a seal when the windows are closed. Secondly, to prevent contaminants from entering the cleanroom when transferring items, a double-layer installation method can be adopted during installation. That is, two sets of guide rail brackets of this application are installed alternately, and then windows are installed on each set. When transferring items, first open the window on the external guide rail bracket, place the item between the two sets of guide rail brackets, close the window on the external guide rail bracket, then open the window on the internal guide rail bracket, take out the item, and close the window on the internal guide rail bracket.

[0047] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
