Description

Technical Field

[0001] This utility model relates to the field of cleanroom door installation and hanging technology, specifically a medical cleanroom door sunken hanger device. Background Technology

[0002] In medical, biopharmaceutical, and laboratory settings where environmental cleanliness and airtightness are extremely critical, medical cleanroom doors serve as key equipment for isolating areas of different cleanliness levels. Their sealing performance and operational stability directly impact the environmental quality and safety of the area. Traditional sliding medical cleanroom doors typically employ a specially designed technical solution for the sliding rails and rollers to achieve effective sealing when closed. During door closure, the sliding rail structure causes the door to sink 5-7mm and move inward 3-5mm, ensuring a tight seal between the sealing strip on the lower sill and the ground. Furthermore, the inner sealing strip of the door is pressed firmly against the subframe sealing strip, thus achieving the required seal.

[0003] However, the aforementioned sealing solution has significant technical limitations: when the door is opened, it needs to be lifted 5-7mm along the hanging rail to return to its normal sliding state, which generates a great deal of pulling force. This pulling force not only places higher demands on the power of the drive motor and the strength of the timing belt, but also imposes strict limitations on the weight of the door itself—due to the limited driving force of the motor, traditional solutions are unsuitable for special door panels such as ultra-heavy radiation shielding doors commonly used in operating rooms, as they cannot provide sufficient lifting power. In addition, long-term high-load operation will also accelerate the wear and tear of components such as the motor and timing belt, reducing the operational stability and service life of the equipment, and failing to meet the stringent reliability requirements of medical settings.

[0004] Therefore, there is an urgent need for a new type of medical cleanroom door hanger device that can effectively reduce the tensile load when the door is opened while ensuring sealing performance, and improve the adaptability and operational stability of the equipment to door panels of different weights. Utility Model Content

[0015] Preferably, a protective rubber strip is provided between the upper protective cover and the front protective cover.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: The medical cleanroom door recessed hanging device provided by this utility model has the following significant beneficial effects compared with the prior art:

[0017] 1. Through the cooperation of the guide rail (including the first guide rail, the second guide rail and the curved third guide rail) and the guiding mechanism, the clean door can sink and tilt inward during the closing process through the guide shaft, so that the bottom sill rubber strip of the door leaf is in close contact with the ground and the inner rubber strip is in close contact with the sub-frame rubber strip, ensuring the sealing effect of the door and meeting the stringent cleanliness requirements of the medical environment.

[0018] 2. The innovatively designed load-bearing mechanism (the concave-convex fit between the load-bearing wheel and the convex track) and guide rail door reversing device (the upper and lower hangers are hinged through the reversing shaft) make the door's downward and inward movements smoother during the door's reversing and movement by guiding the guide wheel along the reversing guide rail. This avoids the huge pulling force generated when the door needs to be lifted upwards when opening in traditional structures, effectively reducing the load on drive components such as motors and synchronous belts, and extending the service life of the equipment.

[0019] 3. The concave track of the load-bearing wheel is matched with the convex track of the support to ensure that the load-bearing wheel rolls stably along the track and avoids deviation;

[0020] The anti-fall mechanism (anti-fall wheel, anti-fall wheel axle, etc.) is embedded in the groove at the bottom of the convex track, which can prevent the door leaf from falling off accidentally and improve the safety of equipment operation.

[0021] The upper cover, front cover, and protective cover rubber strips effectively prevent dust and debris from entering the device, reduce component wear, and ensure long-term stable operation.

[0022] 4. Due to the reduced driving load, this device is not only suitable for ordinary airtight doors, but also meets the hanging requirements of heavy-duty radiation protection doors in scenarios such as operating rooms, thus broadening the application scope of medical clean doors and improving the versatility of the equipment.

[0023] 5. The first and second mounting holes on the connecting plate can be used to adjust the position of the upper hanger and the anti-falling fixing plate, respectively, which facilitates the installation, calibration and maintenance of the device and reduces the difficulty of construction.

The protective cover strip 9 can prevent dust from entering through the gap between the upper and front protective covers.

[0046] In the embodiments of this utility model, specifically, the working principle of this utility model is as follows: When the cleanroom door moves from the first guide rail 21 to the second guide rail 22, the load-bearing wheel moves along the variable guide rail and changes its direction of movement through the third guide rail 23. At this time, the guide wheel 41 changes its direction of movement, thereby causing the connecting plate 51 to change from an upright posture to an inclined posture, which in turn drives the load-bearing wheel 31 to change from an upright rolling posture to an inclined rolling posture. Since the upper hanger is fixedly connected to the connecting plate, the upper hanger also becomes inclined. The lower hanger changes its angle with the upper hanger through the variable shaft. Since the cleanroom door is connected to the lower hanger, under the influence of the cleanroom door's own weight, the lower hanger always remains perpendicular to the bottom surface. This utility model, by adding a guide wheel and a variable guide rail with variable track function, allows the variable shaft to change its angle when the door is lowered or tilted inward. When the door is open, the guide wheel and the guide rail are running normally. When the door is about to close, the variable guide rail changes its angle, forcing the guide wheel to change its angle along with the guide rail, causing the center of the steering shaft to change downward and inward. While ensuring the door's airtightness, it effectively reduces the motor load and improves the equipment's operational stability, thereby solving the door's sealing problem.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
