Description

Technical Field

[0001] The present application relates to the technical field of clean doors, and in particular to a clean door for a dust-free space. Background Art

[0002] Clean doors are usually easy to clean, environmentally friendly, and have strong airtightness. They are suitable for various hospital construction, biomedical laboratories, food processing plants and other places with high requirements for cleanliness and airtightness. While being easy to clean, they can also reduce the breeding and reproduction of bacteria and viruses and reduce cross infection.

[0003] Some existing clean doors are usually equipped with sealing strips around the door frame when they are installed and used. When the door panel is closed, the sealing strip on the door frame is tightly squeezed to achieve sealing isolation of the internal space to keep it clean. However, after the door panel squeezes the sealing strip for a long time, the sealing strip is easily deformed and damaged, resulting in poor sealing effect. Utility Model Content

[0004] In view of the problem of poor sealing effect in the prior art, the utility model specially provides a dust-free space clean door.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] like Figure 1-4 As shown, the embodiment of the utility model discloses a clean door for a dust-free space, including a door frame 1 and a driving mechanism, a door panel 2 is slidably arranged on one side of the door frame 1, a slot 101 is arranged on the side of the door frame 1 close to the door panel 2, a mounting frame 4 is embedded in the slot 101, a sealing gasket 401 abutting against the door panel 2 is arranged on the mounting frame 4, a fixing rod 402 is fixedly arranged on one end of the mounting frame 4 located in the slot 101, a jack matched with the fixing rod 402 is arranged on the side wall of the slot 101, a spring 5 is sleeved on a section of the fixing rod 402 in the slot 101, two ends of the spring 5 abut against the mounting frame 4 and the door frame 1 respectively, a slide groove 102 communicating with the slot 101 is arranged on the side wall of the door frame 1, a slider 6 is slidably arranged in the slide groove 102, one end of the slider 6 located in the slide groove 102 is fixedly connected to the mounting frame 4, and one end of the slider 6 located outside the slide groove 102 is provided with an inclined surface abutting against the door panel 2, and the driving mechanism is arranged on the door frame 1.

[0024] In at least one embodiment, the driving mechanism includes an electric push rod 3, which is fixedly arranged on the top of the door frame 1. The door panel 2 is provided with a groove 201 for matching the electric push rod 3. The output shaft of the electric push rod 3 is connected and fixed to the door panel 2. When the staff starts the electric push rod 3, the electric push rod 3 drives the door panel 2 to slide horizontally along the door frame 1, which is convenient to operate.

[0025] In at least one embodiment, a group of pulleys 8 are rotatably arranged on both sides of the bottom of the door frame 1, and a second slide groove matched with the pulley 8 is provided at the bottom of the door panel 2. The pulley 8 arranged at the bottom of the door frame 1 can support the door panel 2 to avoid direct friction between the bottom of the door panel 2 and the door frame 1 when the door panel 2 slides horizontally, thereby avoiding damage. In addition, the abutment of the pulley 8 in the second slide groove facilitates the electric push rod 3 to push the door panel 2 to slide, thereby realizing the limitation of the door panel 2, and the operation is convenient.

[0026] In at least one embodiment, a countersunk hole is provided at one end of the slider 6 outside the slide groove 102, and a ball 7 is rotatably arranged in the countersunk hole. When the door panel 2 abuts against the inclined surface on the slider 6, the ball 7 on the slider 6 abuts against the door panel 2, thereby avoiding direct friction between the door panel 2 and the door frame 1 during the sliding process, thereby ensuring the service life of the clean door.

[0027] In at least one embodiment, the sliders 6 are in multiple groups and are arranged at intervals on the door panel 2. The multiple groups of sliders 6 drive the installation frame 4 to perform multi-point synchronous sliding, ensuring that the sealing gaskets 401 around the installation frame 4 are in synchronous contact with the door panel 2, thereby improving the sealing effectiveness of the door panel 2.

[0028] In at least one embodiment, an observation window 202 is fixedly provided on the door panel 2, and the staff can observe the situation inside the space through the observation window 202, so that the staff can understand the internal situation in real time.

[0029] In at least one embodiment, the sealing gasket 401 is fixedly connected to the installation frame 4 by adhesive, so as to ensure the connection stability between the sealing gasket 401 and the installation frame 4 and facilitate the staff to load and unload the sealing gasket 401.

[0030] When installing and using the clean door, the staff installs the door panel 2 at the entrance of the space through the door frame 1. When the door panel 2 needs to be opened and closed, the staff drives the door panel 2 to slide horizontally along the door frame 1 through the driving mechanism. In the process of opening the door panel 2, the door panel 2 abuts against the slider 6 on the door frame 1 when sliding. The inclined surface set on the slider 6 makes the door panel 2 squeeze the slider 6 to slide inward along the slide groove 102, thereby driving the installation frame 4 to slide in the card groove 101. At this time, the installation frame 4 squeezes the spring 5 on the fixing rod 402, so that the sealing gasket 401 on the installation frame 4 is separated from the door. The abutment of the plate 2 facilitates the opening of the door panel 2. When the door panel 2 is closed, when the driving mechanism drives the door panel 2 to slide and overlap with the door frame 1, the door panel 2 is disengaged from the abutment with the slider 6. At this time, the mounting frame 4 drives the sealing gasket 401 to slide axially along the fixed rod 402 under the compression of the spring 5, so that the sealing gasket 401 on the mounting frame 4 abuts against the door panel 2, and a tight fit is achieved under the action of the spring 5, thereby ensuring the sealing effect of the clean door. In addition, the arranged spring 5 enables the sealing gasket 401 to effectively abut against the door panel 2 within a certain deformation range, thereby extending the service life of the sealing gasket 401 and further improving the sealing effect.
