[0002] Pass-through windows, as an important isolation device, are widely used between cleanrooms and non-cleanrooms to safely and reliably transfer items and prevent contamination of the cleanroom environment. In hospitals, pharmaceutical factories, and biological laboratories, pass-through windows are used to transfer medicines, reagents, and instruments, effectively ensuring the cleanliness and safety of production and experimental processes. However, existing pass-through windows generally suffer from high costs in terms of manufacturing and maintenance. Their complex mechanical structure and easily damaged parts lead to high repair costs, and operators cannot quickly repair them, requiring professional maintenance personnel, thus increasing the overall cost of use.

[0003] Therefore, this application provides a linkage locking mechanism for the windows and doors on both sides of the transfer window to meet the requirements. Utility Model Content

[0004] The purpose of this application is to provide a linkage locking mechanism for the windows and doors on both sides of a pass-through window, which aims to solve the problems of high cost and high maintenance cost that pass-through windows generally have. The complex mechanical structure and vulnerable parts lead to high repair costs, and operators cannot repair them quickly. They need to be repaired by professional maintenance personnel, which increases the cost of use.

[0005] To achieve the above objectives, this application provides the following technical solution: a linkage locking mechanism for windows on both sides of a transfer window, including a transfer window, which is a frame that is open at both the front and back. Side frames are symmetrically arranged on the left and right sides of the transfer window, and windows are provided at both the front and rear ends of the transfer window. Both sets of windows are hinged to the right side frame. The left side of each window is connected to the left side frame via a limit lock. A locking mechanism is provided in the left side frame, and the locking mechanism is adapted to the window. The locking mechanism also includes a fixed plate, a connecting rod, a tension spring, and a rotating lock block. There are two sets of connecting rods, tension springs, and rotating lock blocks, which are staggered front to back. The connecting rods are hinged to the rotating lock blocks. The fixed plate is installed on the side frame. A tension spring connects the rotating lock blocks to the fixed plate. One set of rotating lock blocks is adapted to one end of the window, and the connecting rod hinged to this set of rotating lock blocks abuts against the other end of the window, so that the windows on both sides of the transfer window have a linkage effect.

[0006] Preferably, the rotating lock block is connected to a locking tongue for fixing and limiting the window door. The rotating lock block has a fixing hole and a connecting rod hole. A spring connecting block is provided between the fixing hole and the connecting rod hole. The rotating lock block is connected to the fixing plate through the fixing hole. The connecting rod is hinged to the rotating lock block through the connecting rod hole, which improves reliability and service life.

[0007] Preferably, the fixing plate is also provided with spring hooks, guide holes and locking blocks. There are two sets of spring hooks, guide holes and locking blocks, which are staggered front and back. The position and size of the locking blocks and fixing holes are matched. The connecting rod passes through the connecting rod hole and slides in the guide hole. The two ends of the tension spring are connected to the spring connecting block and the spring hook respectively, which makes the transfer window easier to install and maintain and reduces production costs.

[0008] Preferably, the spring hook is fishbone shaped, and the fixing plate is provided with a connecting rod baffle corresponding to the position of the connecting rod. The fixing plate is also provided with several threaded holes corresponding to the position of the spring hook, which extends the service life of the tension spring and reduces maintenance costs.

[0009] Preferably, the left side frame has through holes on both sides that are compatible with the connecting rod, and the left side frame also has rectangular holes that are compatible with the lock tongue, so that the windows on both sides of the transfer window have a linkage effect.

[0010] In summary, the technical effects and advantages of this utility model are as follows:

[0011] In this invention, by employing a spring-assisted locking mechanism and combining it with a connecting rod and rotating locking block design, the wear and jamming problems of simple mechanical linkage are effectively avoided, thereby improving the reliability and service life of the transfer window. Even under long-term and high-frequency use, it can ensure stable and reliable operation.

[0012] In this invention, the adjustable fishbone-shaped spring hook and the threaded hole for replacing the limit screw facilitate the adjustment and replacement of the tension spring, reduce maintenance costs and repair difficulty, and even if key components are worn, they can be repaired or replaced through simple operations, thus reducing maintenance costs.

[0020] 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. Example

[0021] refer to Figure 1-5 The transfer window linkage locking mechanism shown includes a transfer window 1, which is a frame that is open at the front and back. Side frames 3 are symmetrically arranged on the left and right sides of the transfer window 1. Window doors 2 are provided at both the front and rear ends of the transfer window 1. Both sets of window doors 2 are hinged to the right side frame 3. Limit locks 5 for locking the window doors 2 are provided on both sides of the left side frame 3. Locking mechanism 4 for linkage of the two sets of window doors 2 is also provided in the left side frame 3. Locking mechanism 4 also includes a fixed plate 41, a connecting rod 44, a tension spring 45 and a rotating lock block 46. There are two sets of connecting rod 44, tension spring 45 and rotating lock block 46, which are staggered front and rear. One end of the connecting rod 44 is hinged to the rotating lock block 46, and the other end of the connecting rod 44 passes through the side frame 3 and abuts against the other end of the window door 2.

[0022] As one implementation method in this embodiment, in order to enable the window door 2 of the transfer window 1 to be opened only on one side at a time, a locking tongue 461 is connected to the rotating lock block 46, and a locking block adapted to the locking tongue 461 is provided on the window door 2. A fixing hole 462 is also provided on the rotating lock block 46 for mounting the rotating lock block 46 on the fixing plate 41. A connecting rod hole 463 for mounting the connecting rod 44 is also provided on the rotating lock block 46, and two connecting rod holes 463 are provided side by side to facilitate the adjustment of the sensitivity of the linkage between the two windows 2 of the transfer window 1. A spring connecting block 464 is also provided on the rotating lock block 46 between the connecting rod hole 463 and the fixing hole 462.

[0023] As one implementation method in this embodiment, in order to reduce the production cost of the equipment, the fixing plate 41 is also cut and machined to form a spring hook 421, a guide hole 422 and a locking block baffle 423. The locking block baffle 423 is adapted to the size of the fixing hole 462. The connecting rod 44 slides in the guide hole 422 through the connecting rod hole 463. The two ends of the tension spring 45 are respectively connected to the spring connecting block 464 and the spring hook 421. The spring hook 421 is fishbone shaped, so that after the tension spring 45 has been used for a long time, its service life can be extended by adjusting its position on the spring hook 421. A threaded hole 425 is provided at the end of the spring hook 421, so that after the spring hook 421 has been worn irreparably for a long time, a screw can be installed in the threaded hole 425 to replace the effect of the spring hook 421, reducing the maintenance cost. In order to make the connecting rod 44 easier to install and position, the fixing plate 41 is provided with a connecting rod baffle 424 corresponding to the position of the connecting rod 44.

[0024] As one embodiment of this example, the left side frame 3 has through holes on both sides that are compatible with the connecting rod 44, and also has rectangular holes that are compatible with the locking tongue 461. The two doors 2 of the transfer window 1 can be linked by the locking mechanism 4. The transfer window 1 is also equipped with a disinfection device for disinfecting items.

[0025] The working principle of this utility model is as follows: During use, both doors 2 of the pass-through window 1 are closed and limited by the limit lock 5. The two doors 2 are located on opposite sides of the wall, with the left side being the living area side and the right side being the clean area side. Neither door 2 is limited by the locking tongue 461 on the rotating lock block 46. First, the limit lock 5 on the living area side is released, allowing the door 2 on that side to open directly. As the door 2 on the living area side opens, the rotating lock block 46 is no longer pressed by the connecting rod 44 on the living area side. The tension spring 45 on the clean area side pulls the rotating lock block 46. Under the action of the tension spring 45, the rotating lock block 46 rotates around the lock block baffle 423 on the fixed plate 41, causing the locking tongue 461 on the rotating lock block 46 to limit the window 2 on the clean area side. Even if the limit lock 5 on the clean area side is opened, the corresponding window 2 still cannot be opened. Then, the items to be transferred can be placed inside the transfer window 1 from the living area side. After that, the window 2 on the living area side is closed. When the windows 2 on both sides of the transfer window 1 are the same When closed, the locking mechanism 4 does not limit the window / door 2; it is only limited by the limit lock 5 on the side frame 3. After the window / door 2 on the living area side is closed, the items are disinfected by the disinfection equipment in the transfer window 1, and then the limit lock 5 on the clean area side is opened, so that it no longer limits the window / door 2 on the same side. Then the window / door 2 on the clean area side can be opened to take out the disinfected items. When the window / door 2 on the clean area side is opened, the connecting rod 44 on the clean area side no longer presses the rotating lock block 46, so that the rotating lock block on the living area side... 46. ​​The rotating lock block 46 is pulled by the tension spring 45. Under the action of the tension spring 45, the rotating lock block 46 rotates around the lock block baffle 423 on the fixed plate 41, so that the lock tongue 461 on the rotating lock block 46 limits the window 2 on the living area side. Even if the limit lock 5 on the living area side is opened, the corresponding window 2 still cannot be opened. Then, the staff can take out the disinfected items from the transfer window 1 from the clean area side. After that, the windows 2 on both sides are reset and closed to complete the transfer of items.

[0026] After prolonged use, when the tension of the tension spring 45 is insufficient, the position of the tension spring 45 on the spring hook 421 can be adjusted. Through the fishbone-shaped spring hook 421, the tension spring 45 can be adjusted multiple times, which improves the service life of the tension spring 45 and reduces maintenance costs. If the spring hook 421 is worn too badly after long-term use and cannot be repaired, a limit screw can be installed in the threaded hole 425 on the fixing plate 41 to replace the spring hook 421, thereby reducing maintenance costs.
