[0038] Reference below Figure 1-Figure 6 A multi-layer fixed structure clean door according to an embodiment of the utility model is described.

[0039] like Figure 1-Figure 6As shown, the multi-layer fixed structure clean door includes a door panel 100 and a door frame 200, and the door panel 100 is hinged on the door frame 200. It also includes a forged hinge 300, an elastic sealing strip 400 and a guide lock 500. One end of the forged hinge 300 is fixedly connected to the door frame 200, and the other end is fixedly connected to the door panel 100. When the door panel 100 is closed, it fits with the outer surface of the door frame 200. Specifically, the fitting part of the door panel 100 and the door frame 200 of this embodiment is the side of the door frame 200 parallel to the wall and protruding from the wall, and the door frame 200 adopts a four-side covering structure. When the door panel 100 and the door frame 200 are closed, the four sides of the door panel 100 and the four sides of the door frame 200 are in a fitting state, so that the door frame 200 and the door panel 100 are completely fitted, and the sealing effect is better.

[0040] The elastic sealing strip 400 is arranged around the periphery of the door panel 100. When the door panel 100 is closed, the elastic sealing strip 400 is deformed to fill the gap between the door panel 100 and the door frame 200. The elastic sealing strip 400 can adopt a segmented structure or an annular structure. The segmented elastic sealing strip 400 covers the periphery of the door panel 100, and the annular elastic sealing strip 400 is embedded in the groove of the door panel 100. In this embodiment, a segmented elastic sealing strip 400 is adopted. When the door panel 100 and the door frame 200 are closed, the elastic sealing strip 400 between the door panel 100 and the door frame 200 is elastically deformed to fill the connection gap between the door panel 100 and the door frame 200.

[0041] The guide lock member 500 is arranged between the door panel 100 and the door frame 200, and includes a guide latch 510 and an elastic lock pin 520. The guide latch 510 is arranged on one side of the door panel 100, and the elastic lock pin 520 is arranged on one side of the door frame 200. When the elastic lock pin 520 and the guide latch 510 are buckled, the elastic sealing strip 400 is deformed and compressed. Specifically, the locking positions of the guide latch 510 and the elastic lock pin 520 are adjustable, and are adjusted according to the thickness or aging degree of the elastic sealing strip 400. When the deformation capacity of the elastic sealing strip 400 is reduced after long-term use, the insertion depth of the guide latch 510 and the elastic lock pin 520 is adjusted so that the elastic sealing strip 400 is continuously fitted with the door panel 100 and the door frame 200.

[0042] The door frame 200 further includes a control component 600 which is embedded in the door frame 200 . The control component 600 is electrically connected to the guide lock element 500 . The control component 600 is used to control the elastic lock pin 520 to separate from the guide latch pin 510 .

[0043] In some embodiments of the present invention, Figure 1 and Figure 2As shown, the forged hinge 300 includes an L-shaped hinge 310 and a hinge hinge seat 320 . The hinge hinge seat 320 is welded to the surface of the door frame 200 , the L-shaped hinge 310 is welded to the door panel 100 , and the L-shaped hinge 310 is hinged to the hinge hinge seat 320 .

[0044] Specifically, when the door panel 100 and the L-shaped hinge 310 rotate around the hinge hinge seat 320, the door panel 100 and the L-shaped hinge 310 rotate synchronously, and the L-shaped hinge 310 and the door panel 100 are welded into a whole. Compared with the hinge structure of the existing clean door, the forged hinge 300 has a stronger connection stability and is widely used in the connection of the automobile door frame 200. It can avoid the displacement problem of the door panel 100 caused by the sinking of the hinge structure, and further improve the closing stability of the door panel 100 and the door frame 200.

[0045] In some embodiments of the present invention, Figure 5 As shown, the middle of the elastic sealing strip 400 is hollowed out, and an exhaust hole 410 is provided on one side of the elastic sealing strip 400 close to the middle of the door panel 100, and the exhaust holes 410 are arranged at equal intervals along the extending direction of the elastic sealing strip 400. Specifically, the exhaust holes 410 of the elastic sealing strip 400 on the four sides of the door panel 100 are all opened toward the middle of the door panel 100. When the door panel 100 is closed, the air in the internal cavity of the elastic sealing strip 400 can be discharged from the exhaust holes 410 during the deformation process, thereby improving the deformation performance of the elastic sealing strip 400.

[0046] In a further embodiment, the cross section of the elastic sealing strip 400 is square. The elastic sealing strips 400 on four sides are spliced ​​to form a whole, and the middle parts of the elastic sealing strips 400 are connected to each other, which is conducive to uniform deformation of the elastic sealing strips 400 on the four sides.

[0047] In some embodiments of the present invention, Figure 4 and Figure 6 As shown, a guide slope 521 is provided on the side of the elastic lock pin 520 facing the guide latch 510. When the guide latch 510 is pressed toward the elastic lock pin 520, the guide slope 521 guides the elastic lock pin 520 to move upward, so that the guide latch 510 is inserted. Specifically, when the guide latch 510 is inserted into the elastic lock pin 520, the component force of the guide latch 510 acting on the guide slope 521 causes the elastic lock pin 520 to move upward, so that the guide latch 510 is combined with the elastic lock pin 520 more quickly.

[0048] In a further embodiment, Figure 4 and Figure 6As shown, the guide latch 510 includes a roller 511 and a lock pin seat 512, the roller 511 is rotatably connected to the top of the lock pin seat 512, the roller 511 abuts against the guide slope 521, and when the guide slope 521 passes over the roller 511, the elastic lock pin 520 is inserted into the lock pin seat 512. Specifically, the roller 511 contacts the guide slope 521, converting the sliding friction into rolling friction, reducing the friction, and making the elastic lock pin 520 move upward more smoothly.

[0049] In some embodiments of the present invention, Figure 6 As shown, the lock pin seat 512 includes a base 512-1 and two fixing plates 512-2, the fixing plates 512-2 are fixedly connected to the base 512-1, the two fixing plates 512-2 are spaced apart to form a receiving cavity, and the tops of the two fixing plates 512-2 are rotatably connected to the roller 511. Specifically, when the elastic lock pin 520 passes over the roller 511, it is reset due to the loss of external force, and is inserted into the receiving cavity, so that the elastic lock pin 520 and the guide latch 510 are mutually engaged.

[0050] In some embodiments of the present invention, Figure 6 As shown, the roller 511 is detachably connected to the lock pin seat 512, and the diameter of the roller 511 is replaceable. Specifically, as the diameter of the roller 511 increases, the deformation of the elastic sealing strip 400 increases. As the diameter of the roller 511 decreases, the deformation of the elastic sealing strip 400 decreases. According to the use state of the elastic sealing strip 400, a suitable roller 511 is selected for adjustment.

[0051] In some embodiments of the present invention, the guide lock member 500 uses a solenoid valve structure to control the elastic lock pin 520 to unlock the guide latch pin 510. During the unlocking process, the elastic lock pin 520 is sucked by the solenoid valve, so that the elastic lock pin 520 is separated from the guide latch pin 510.

[0052] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, an observation window 110 is provided on the door panel 100 , and the observation window 110 is sealed and connected to the door panel 100 .
