Description

Technical Field

[0001] The utility model belongs to the technical field of clean doors, and in particular relates to a clean door for an operating room. Background Art

[0002] A clean door is a special door improved based on an ordinary door. It is generally installed inside clean workshops, hospitals and pharmaceutical factories. The installation of a clean door can reduce the amount of dust from the outside entering the room, thereby improving the cleanliness of the room. Clean doors are corrosion-resistant, high-strength, dust-free on the surface and beautiful in appearance, making them widely used in some occasions that require cleanliness.

[0003] A Chinese patent with announcement number CN221373352U discloses a clean door for a clean room, comprising a clean door body, a door frame being arranged on the surface of the clean door body, a sealing assembly being arranged between the clean door body and the door frame, sealing assemblies being arranged on all four sides of the clean door body, a hinge being installed on the back of the door frame, the clean door body being fixed to the door frame by means of the hinge, a shielding assembly being arranged on the back of the clean door body, the sealing assembly comprising a square groove being arranged at the lower end of the door frame, a rubber sealing block being slidably connected to the inner wall of the square groove, which solves the problem that sealing strips need to be arranged on all four sides of the clean door when ensuring the sealing property of the clean door, so as to ensure the sealing property, the sealing strips are generally fixed to the clean door with glue, and the viscosity of the glue is reduced after the door is opened and closed for many times and collides, which may cause the sealing strips to come unglued, thereby resulting in the problem of reduced sealing property of the clean door.

[0004] However, in actual use, since the clean door body rotates and closes around the door frame, the rubber sealing strip on the side of the clean door body close to the rotation center will first abut against the door frame when the door is closed. The local abutment at this point will drive the entire rubber sealing strip to shrink into the square frame, which will cause local fatigue of the rubber sealing strip, that is, the service life of the rubber sealing strip close to the rotation center is shorter, thereby affecting the service life of the entire rubber sealing strip. Utility Model Content

[0005] The utility model aims to provide an operating room clean door to solve the above-mentioned problem that the short service life of the existing rubber sealing strips locally affects the overall service life.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: an operating room clean door, comprising

[0007] The door frame has a groove on the inner side, and rubber sealing strips are installed horizontally on both the upper and lower sides of the groove;

[0008] The door body is rotatably mounted on the door frame and matched with the groove. The upper and lower sides of the door body are provided with sealing grooves, which are matched with the rubber sealing strips.

[0009] The principle and effect of this technical solution:

[0010] 1. Through the rubber sealing strips arranged horizontally up and down and the corresponding sealing grooves opened on the door body, the door body will not excessively press the rubber sealing strip when opening or closing, that is, there is no need to locally press or deform the rubber sealing strip, and the door opening or closing operation can be completed. Since the deformation times or deformation amount of the rubber sealing strip are reduced, the service life of the rubber sealing strip is increased.

[0011] 2. When the door is closed, the rubber sealing strip is placed in the sealing groove, making the gap line between the door and the door frame more complicated, which makes it difficult for dust and impurities to pass through, thereby improving the sealing effect.

[0012] The utility model is further configured as follows: a receiving groove is opened on the door frame, a telescopic spring is installed in the receiving groove, a rubber sealing strip is slidably inserted in the receiving groove, and the rubber sealing strip is fixed to the telescopic spring.

[0013] The principle and effect of the technical solution: the setting of the accommodating groove and the telescopic spring allows the rubber sealing strip to transitionally press or give way and buffer the accommodating groove of the door frame in a telescopic manner, that is, when the door body is closed, the telescopic spring can be driven to expand and contract by pressing the rubber sealing strip, thereby buffering the closing of the door body, and after the door body is closed, the rebound force of the telescopic spring will drive the rubber sealing strip to fully press against the accommodating groove, thereby improving the sealing effect, and when opening the door, the rebound force of the telescopic spring and the rubber sealing strip will drive the door body to leave the door frame, making it easier to open the door.

[0014] The utility model is further configured to include a side sealing unit, which includes a push plate, a panel, a side sealing plate and an elastic component. The panel is fixed on the door frame, and a sliding cavity connected to the outside is provided between the panel and the door frame. The elastic component is installed in the sliding cavity. The side sealing plate is slidably inserted in the sliding cavity and is connected to the elastic component. A guide sliding surface is formed on the side of the side sealing plate away from the groove. The push plate is slidably arranged on the door body and abuts against the side sealing plate.

[0015] The principle and effect of this technical solution: through the setting of the side sealing plate, the guide sliding surface and the elastic component, when the door body is closed, it can drive the side sealing plate to compress the elastic component by pressing the guide sliding surface, thereby making way for the rotation of the door body, and after the door body is closed, the side sealing plate will automatically reset under the drive of the elastic component, thereby blocking and abutting the door gap, and at the same time can improve the impact strength of the door body when it is closed, and through the setting of the push plate, when the door body needs to be opened, the operator can turn the door handle with one hand and push the push plate with the other hand so that the push plate drives the side sealing plate to be stored in the sliding cavity, thereby completing the two-way giving way of the side sealing plate to the movement of the door body.

[0016] The utility model is further configured as follows: the elastic component includes a guide rod and a compression spring, the guide rod is fixed in the sliding cavity, and the side sealing plate is slidably sleeved on the guide rod, the compression spring is sleeved on the guide rod and is located on the side of the side sealing plate away from the door body.

[0017] The principle and effect of this technical solution: by setting the guide rod, the sliding of the side sealing plate can be guided and limited, and by setting the compression spring, the side sealing plate will spontaneously move closer to the door body under the elastic force of the compression spring when no external force is applied, thereby achieving the function of automatic resetting.

[0018] The utility model is further configured to include an outward opening unit, which includes a pull plate and a connecting rod. A pull groove connected to the sliding cavity is opened on the door frame. The connecting rod is slidably fitted in the pull groove, and one end is connected to the side sealing plate, and the other end is connected to the pull plate. The pull plate is slidably fitted to the side of the door frame away from the panel.

[0019] The principle and effect of this technical solution: the side sealing plates are connected and transmitted through the connecting rod, so that the movement of the side sealing plates can also drive the movement of the dial plates, or be controlled to move by the dial plates. When people outside the door body need to enter the door body, the side sealing plates can be driven to leave the outside of the door body by controlling the dial plates, so that the door body can be opened normally.

[0020] The utility model is further configured such that: the paddle completely covers the paddle slot.

[0021] The principle and effect of this technical solution: by making the shift plate completely cover the shift groove, the connecting rod drives the shift plate to move without causing the shift groove to be exposed to the outside world, thereby improving the dustproof effect of the device and avoiding the situation where the dustproof function is reduced due to the setting of the outward opening unit.

[0022] The utility model is further configured as follows: a shielding cloth is arranged on one side of the door body away from the groove.

[0023] The principle and effect of the technical solution: the setting of the shielding cloth enables the observation window of the door body to be shielded or opened according to the use requirements, thereby providing a variety of options. BRIEF DESCRIPTION OF THE DRAWINGS
