Description

Technical Field

[0001] The utility model relates to the technical field of airtight doors, in particular to a clean fireproof airtight door. Background Art

[0002] The airtight door is a sliding door that integrates airtightness, sound insulation, heat preservation, pressure resistance, dust prevention, fire prevention and radiation protection. It is generally used in hospitals, food factories, industrial plants and other places with high requirements for sound insulation, heat insulation and airtightness.

[0003] There are usually three ways to seal the bottom of a sliding airtight door. One is to set a track, and the other is to set a slide. The two methods are similar. The bottom of the door body is connected to the track or slide, which can not only support the door body, but also play a certain sealing role. Another method is to suspend the door body, and a sealing strip is set at the bottom of the door body.

[0004] For example, a medical automatic translation airtight door disclosed in Chinese patent CN220705549U realizes sealing and support of the bottom of the door body by setting a slide groove at the bottom, and connecting the bottom of the door body in the slide groove;

[0005] Another example is an induction electric translation airtight door disclosed in Chinese patent CN217028603U, which is provided with a track at the bottom, and the bottom of the airtight door plate is slidably connected with the track to achieve support and sealing of the airtight door plate;

[0006] Another example is a translational airtight door disclosed in Chinese patent CN206053728U. The translational airtight door is achieved by providing a sealing strip at the bottom, which is in contact with the ground, so as to seal the airtight door panel.

[0007] However, the above two sealing methods for the bottom of the door body have the following defects while solving the problem:

[0008] In the form of a slide groove provided at the bottom of the door body, the slide groove is located below the ground, so dust is easily accumulated in the slide groove, and the slide groove is narrow and difficult to clean. If it is not cleaned in time, it will affect the movement of the door body; in the form of a track provided at the bottom of the door body, the track protrudes above the ground. If it is used in a hospital, wheelchairs and medical beds will often pass by, which will not only affect the passage of wheelchairs and medical beds, but also crush and deform the track; in the form of a sealing strip provided at the bottom of the door body, when the door body slides horizontally, the friction between the sealing strip and the ground will cause irreversible wear and a short service life. Utility Model Content

[0009] The purpose of the utility model is to solve at least one of the technical defects described in the background technology.

[0010] To this end, one purpose of the utility model is to propose a clean fireproof airtight door, aiming to solve the problem that the slide groove or slide rail arranged under the airtight door in the prior art is prone to dust accumulation or deformation due to crushing and trampling, resulting in the door body being unable to move, or the bottom sealing strip is easily worn and has a short life.

[0011] In order to achieve the above-mentioned purpose, an embodiment of the utility model on one hand provides a clean fireproof airtight door, including a top frame, a door body, a lifting plate and a cover, characterized in that a slide groove is fixedly connected to the lower part of the interior of the top frame, a positioning plate is fixedly connected to the top of the door body, one side of the positioning plate is rotatably connected to a roller, the positioning plate is slidably connected to the inside of the slide groove through the roller, a storage groove is provided at the bottom of the door body, a positioning groove is provided at the top of the door body, the positioning groove and the storage groove are connected, a positioning rod is fixedly connected to the top of the lifting plate, the positioning rod is slidably inserted in the positioning groove, a sealing strip is fixedly installed at the bottom of the lifting plate, the top end of the positioning rod is fixedly connected to a traction rod, a support bar is fixedly connected to the lower part of the interior of the top frame, the traction rod is overlapped on the top of the support bar, and a slope is provided at one end of the support bar, and a cover is fixedly installed on the front side of the top frame.

[0012] Preferably, any of the above schemes is that a positioning block is fixedly connected to the lower part of the interior of the top frame, the positioning block is located on the side of the support bar with a slope, and a guide plate is fixedly connected to the top of the positioning block close to the support bar, and the guide plate is located above the slope, ensuring that the sealing strip can descend smoothly and is fully sealed with the ground.

[0013] Preferably, any of the above schemes is provided with a limiting groove at the bottom of the lifting plate, and the sealing strip is slidably inserted in the limiting groove, so as to facilitate the replacement of the sealing strip.

[0014] Compared with the prior art, the advantages and beneficial effects of the utility model are:

[0015] 1. When the door is opening, the sealing strip does not contact the ground, and there is no protrusion or depression on the bottom of the door, which will not affect the opening and closing of the door. The bottom sealing strip rarely rubs against the ground, resulting in less wear and tear, which extends the service life of the sealing strip.

[0016] 2. When closing the door, the guide plate can provide downward pressure on the traction rod, thereby ensuring that the lifting plate and the sealing strip can smoothly descend to contact the ground to achieve sealing. The structure is simple and reliable, which improves practicality.

[0017] 3. By setting a limit groove at the bottom of the lifting plate, the sealing strip can be slidably connected in the limit groove. When the sealing strip is aged and corroded, it is convenient to replace the sealing strip.

A support bar 12 is fixedly connected to the lower part of the top frame 1. The traction rod 34 is overlapped on the top of the support bar 12, and the support bar 12 supports the traction rod 34. At this time, the lifting plate 3 is located inside the storage groove 23, and the sealing strip 32 does not contact the ground, and a slope 121 is provided at one end of the support bar 12. When the traction rod 34 slides along the slope 121 to the bottom of the support bar 12, the lifting plate 3 descends, so that the sealing strip 32 at the bottom contacts the ground to achieve a sealing effect. A cover 4 is fixedly installed on the front side of the top frame 1.

[0032] Specifically, a first sealing plate 14 is fixedly connected to the bottom of one end of the top frame 1, and a sealing gasket is provided on one side of the first sealing plate 14. The door body 2 moves toward the direction of the first sealing plate 14 to close the door, and when one side of the door body 2 contacts the side of the first sealing plate 14, the side sealing of the door body 2 is achieved.

[0035] Specifically, Figure 2 and Figure 3 As shown, a plurality of threaded tubes 16 are fixedly connected inside the top frame 1, and a plurality of through holes 41 are opened at positions corresponding to the threaded tubes 16 on one side of the cover 4. The cover 4 can be fixedly installed on the front side of the top frame 1 by using screws to penetrate the through holes 41 and threadably connect with the threaded tubes 16.

[0036] Embodiment 2:

[0037] like Figure 3 As shown, on the basis of Example 1, a positioning block 13 is fixedly connected to the lower part of the interior of the top frame 1, and the positioning block 13 is located on the side of the support bar 12 with a slope 121, and a guide plate 131 is fixedly connected to the side of the top of the positioning block 13 close to the support bar 12, and the guide plate 131 is located above the slope 121. When the door body 2 is closed, the traction rod 34 reaches the top of the slope 121 and the bottom of the guide plate 131, and then continues to close the door body 2. The traction rod 34 is restricted by the guide plate 131 and can only move downward at an angle, which can avoid the problem of the lifting plate 3 and the sealing strip 32 being stuck in the storage groove 23 and not falling, and the guide plate 131 can provide downward pressure on the traction rod 34, so that the sealing strip 32 can be close to the ground to ensure air tightness.

At this time, the traction rod 34 rises along the slope 121 to the top of the support bar 12, and the traction rod 34 pulls the lifting plate 3 upward through the positioning rod 33, so that the lifting plate 3 and the sealing strip 32 enter the storage groove 23, so that the sealing strip 32 does not contact the ground during the opening process of the door body 2;

[0044] When closing the door, the motor 5 drives the door body 2 to approach the first sealing plate 14, and the traction rod 34 slides in the direction of the guide plate 131. When the traction rod 34 enters between the slope 121 and the guide plate 131, the traction rod 34 descends along the slope 121, so that the lifting plate 3 and the sealing strip 32 descend. After the door body 2 is closed, the sealing strip 32 contacts the ground to achieve sealing.

[0045] Compared with the prior art, the present invention has the following beneficial effects:

[0046] 1. When opening the door, the traction rod 34 rises along the slope 121 to the top of the support bar 12, and the traction rod 34 pulls the lifting plate 3 upward through the positioning rod 33, so that the lifting plate 3 and the sealing strip 32 enter the storage groove 23, so that the sealing strip 32 does not contact the ground during the opening of the door body 2. When closing the door, when the door body 2 is about to be closed, the traction rod 34 descends along the slope 121, so that the lifting plate 3 and the sealing strip 32 descend. After the door body 2 is closed, the sealing strip 32 contacts the ground to achieve sealing, so that there is no protrusion or depression at the bottom of the door body 2, which will not affect the opening and closing of the door body 2, and the bottom sealing strip 32 rarely rubs against the ground, so that the wear is small, thereby extending the service life of the sealing strip 32.

[0047] 2. By setting the guide plate 131, and the guide plate 131 is located above the slope 121, when the door body 2 is closed, the guide plate 131 can provide downward pressure on the traction rod 34, thereby ensuring that the lifting plate 3 and the sealing strip 32 can smoothly descend and contact the ground to achieve sealing. The structure is simple and reliable, and the practicality is improved.

[0048] 3. By setting a limiting groove 31 at the bottom of the lifting plate 3, the sealing strip 32 is slidably connected in the limiting groove 31. When the sealing strip 32 is aged and corroded, it is convenient to replace the sealing strip 32.
