[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A clean room door comprises a door panel, a first connecting structure arranged between the upper part of the door panel and a door frame, and / or a second connecting structure arranged at the lower part of the door panel, wherein the first connecting structure and / or the second connecting structure are used to realize the rotation of the door panel and have a tendency to rotate and close after the door panel is opened, the first connecting structure comprises a first rotating shaft, the second connecting structure comprises a second rotating shaft, and the axis center lines of the first rotating shaft and the second rotating shaft coincide and are located in the vertical plane where the door panel is located.

[0007] According to some preferred implementation aspects of the present invention, the bottom of the first rotating shaft is fixedly connected to the top of the door panel and rotates with the door panel; the top of the first rotating shaft extends upward to the door frame. That is, the upper part of the door panel is fixedly connected to the first rotating shaft, and the first rotating shaft is connected to the door frame through the first rotating shaft. When the door panel rotates, the first rotating shaft rotates along its axis.

[0008] According to some preferred implementation aspects of the present invention, a rotating member is provided at the top of the first rotating shaft, a supporting member is provided on the door frame, the top of the first rotating shaft passes through the supporting member, and the rotating member is located above the supporting member. Both ends of the supporting member are connected to the door frame. The door panel can be lifted and rotated at the upper part of the door panel through the rotating member and the supporting member.

[0009] According to some preferred embodiments of the present invention, the support member has a lowest point in a horizontal position, and extends from the lowest point to both sides and upward, and the extension direction is located in the plane where the door frame is located. The lowest point of the support member is a line or a plane, and its extension direction is perpendicular to the vertical plane where the door panel is located.

[0010] According to some preferred implementation aspects of the present invention, the support member is used to have a tendency to move toward the lowest point when the rotating member is located at a position other than the lowest point of the support member. The purpose of setting the support member and the rotating member is that when the rotating member moves to a position other than the lowest point, the rotating member has a tendency to move toward the lowest point of the support member under the action of the gravity of the door panel, and by utilizing this tendency, the door panel can be automatically closed without relying on an additional door closer. When the rotating member moves to the lowest point, the door is closed.

[0011] According to some preferred embodiments of the present invention, the support member includes two symmetrically arranged inclined plates, and the angle between the inclined plates and the horizontal plane is 5-30°, that is, the support member gradually rises from the middle to both sides, and the first rotating shaft passes through the lowest point (middle) of the support member to achieve the above-mentioned rotating member having a tendency to move toward the lowest point.

[0012] According to some preferred implementation aspects of the present invention, the two inclined plates have a mounting portion on one side away from each other, and the mounting portion is used to be connected to a door frame.

[0013] According to some preferred implementation aspects of the present invention, a dust cover for covering the supporting member and the rotating member is installed on the mounting portion.

[0014] According to some preferred embodiments of the present invention, a cross bar is arranged on the top of the first rotating shaft, the rotating members are arranged at both ends of the cross bar, and the size of the support member is larger than the area where the two rotating members rotate one circle. The rotating members are rotatably arranged at the ends of the cross bar and are symmetrically arranged to be evenly stressed. The projection of the support member on the horizontal plane is rectangular or circular. The first rotating shaft passes through the center of the support member.

[0015] According to some preferred embodiments of the present invention, the crossbar and the first rotating shaft are vertically arranged, and the first rotating shaft rotates along its axis to drive the crossbar to rotate in a horizontal plane and drive the rotating member to rotate on the supporting member.

[0016] When the rotating member is at the lowest point, the clean room door is in a closed state, the door panel and the door frame are in the same vertical plane, and the horizontal position of the first rotating shaft and the door panel is at the lowest. When the door needs to be opened, force acts on the door panel, the door panel rotates, the first rotating shaft rotates, the cross bar rotates, and the rotating member is driven to rotate on the support member, moving from the lowest point to both sides, and the horizontal position of the rotating member, the first rotating shaft and the door panel is raised. At this time, the projections of the door panel and the door frame on the horizontal plane are set at an angle, and the clean room door is in an open state. When the force acting on the door panel is removed, driven by the deadweight of the door panel, based on the structural setting of the support member, the rotating member automatically moves to the lowest point of the support member, drives the door panel to gradually close through the first rotating shaft, and the clean room door returns to the closed state.

[0017] According to some preferred embodiments of the present invention, the second connection structure includes a first connection body arranged at the lower part of the door panel and a second connection body arranged on the door frame, the lower part of the second rotating shaft is connected to the second connection body, the upper part of the second rotating shaft extends upward into the first connection body, and the first connection body moves synchronously with the door panel. That is, the first connection body is fixed at the lower part of the door panel and rotates with the door panel, while the second rotating shaft and the second connection body are fixed, and the second rotating shaft rotates relative to the first connection body. The second connection structure is used to support the door panel, and also has the function of automatically closing the door, so that the clean room door can be automatically closed after it is opened.

The end of the elastic member is located in the sleeve to prevent the elastic member from directly contacting the second rotating shaft, and the elastic member and the second rotating shaft from getting stuck when the first connecting body rotates. The height of the notch is greater than the diameter of the sleeve to prevent the sleeve from driving the second rotating shaft to move upward and causing it to fall off the second connecting body.

[0020] Preferably, the edge of the notch is arc-shaped to prevent the second shaft from getting stuck with the elastic member or the sleeve when the first connector rotates. Preferably, the notch is formed by cutting off half of a portion of the second shaft, that is, in the closed state, the side of the notch opposite to the sleeve is a plane, so that the first connector can be easily returned to the original position through the notch and the elastic member to achieve automatic door closing.

[0021] According to some preferred implementation aspects of the present invention, the second rotating shaft includes a fixing portion for fixing with the second connecting body and a rotating portion for cooperating with the elastic member, the notch is provided on the rotating portion, and the rotating portion is accommodated in the first accommodating groove. The fixing portion is (quasi) rectangular or polygonal to fix the second connecting body and the second rotating shaft to prevent the second rotating shaft from rotating. During installation, driven by the deadweight of the door panel, the lower portion of the second rotating shaft is inserted into the corresponding hole of the second connecting body.

[0022] According to some preferred implementation aspects of the present invention, the door frame includes two columns and a crossbeam located between the tops of the two columns, the first connection structure is arranged between the door panel and the crossbeam, the lower end of one of the columns has a support seat, and the second connection structure is arranged between the door panel and the support seat. The support seat is formed by extending the lower end of the column toward the door panel, and has the same extension direction as the crossbeam.

[0023] According to some preferred embodiments of the present invention, the edge of the door panel has a sealing mechanism, such as a sealing ring or a sealing strip.

[0024] According to some preferred implementation aspects of the present invention, the clean room door has a closed state and an open state. In the closed state, the door panel and the door frame are located in the same vertical plane. In the open state, the projections of the door panel and the door frame on the horizontal plane are arranged at an angle. In the open state, the door panel can realize two-way door opening and closing and automatic door closing by the dead weight of the door panel under the action of the first connection structure and the second connection structure.

[0025] The present invention also provides a clean room comprising the clean room door as described above.

[0026] Due to the implementation of the above technical solution, the present invention has the following advantages compared with the prior art: the clean room door of the present invention eliminates the traditional door lock and other door closers, and realizes the rotation of the door panel and the opening and closing of the door by setting the first connection structure and the second connection structure.

DETAILED DESCRIPTION

[0038] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0039] like Figure 1-9 As shown, the clean room of this embodiment is provided with a clean room door 1. The clean room door 1 includes a door panel 2, a first connecting structure 41 arranged between the upper part of the door panel 2 and the door frame 3, and a second connecting structure 42 arranged at the lower part of the door panel 2. The first connecting structure 41 and the second connecting structure 42 are used to realize the rotation of the door panel 2 and have a tendency to rotate and close after the door panel 2 is rotated and opened. The main body of the door panel 2 is metal, and a handle 8 and a transparent observation window 7 are also arranged on the door panel 2. The edge of the door panel 2 has a sealing mechanism, such as a sealing ring or a silicone sealing strip 9. The door frame 3 includes two columns 31 and a crossbeam 32 located between the tops of the two columns 31. The first connecting structure 41 is arranged between the door panel 2 and the crossbeam 32, and the lower end of one of the columns 31 has a support seat 69, and the second connecting structure 42 is arranged between the door panel 2 and the support seat 69. The support seat 69 is formed by extending the lower end of the column 31 toward the door panel 2, and is in the same extension direction as the crossbeam 32.

[0040] The first connection structure 41 includes a first rotating shaft 51, a cross bar 54 disposed at the upper end of the first rotating shaft 51, rotating members 52 located at both ends of the cross bar 54, and a supporting member 53 fixed to the door frame 3. The supporting member 53 is connected to the door frame 3 at both ends close to the column 31. The top of the first rotating shaft 51 passes through the supporting member 53, and the rotating member 52 is located above the supporting member 53. The door panel 2 can be lifted and rotated at the upper part of the door panel 2 by the rotating member 52 and the supporting member 53.

[0041] The bottom of the first rotating shaft 51 is fixedly connected to the top of the door panel 2 through the mounting member 56, and rotates with the door panel 2; the top of the first rotating shaft 51 extends upward into the door frame 3. That is, the upper part of the door panel 2 is fixedly connected to the first rotating shaft 51, and the first rotating shaft 51 is connected to the door frame 3 through the first rotating shaft 51. When the door panel 2 rotates, the first rotating shaft 51 rotates along its axis.

[0042] The support member 53 has a lowest point in the horizontal position, and extends from the lowest point to both sides and upward, and the extension direction is located in the plane where the door frame 3 is located. The support member 53 is used to have a tendency to move toward the lowest point when the rotating member 52 is located at a position other than the lowest point of the support member 53. The lowest point of the support member 53 is a line or a surface, and its extension is perpendicular to the vertical plane where the door panel 2 is located. The purpose of setting the support member 53 and the rotating member 52 is that when the rotating member 52 moves to a position other than the lowest point, the rotating member 52 has a tendency to move toward the lowest point of the support member 53 driven by the gravity of the door panel 2. By utilizing this tendency, the door panel 2 can achieve automatic door closing without relying on an additional door closer. When the rotating member 52 moves to the lowest point, the door closing is completed.

[0043] Specifically, the support member 53 includes two symmetrically arranged inclined plates, and the angle between the inclined plates and the horizontal plane is 5-30°, that is, the top surface of the support member 53 gradually rises from the middle to both sides, and the first rotating shaft 51 passes through the lowest point (middle) of the support member 53 to achieve the above-mentioned rotating member 52 having a tendency to move toward the lowest point.

[0044] The crossbar 54 and the first rotating shaft 51 are arranged vertically. The first rotating shaft 51 rotates along its axis to drive the crossbar 54 to rotate in the horizontal plane, and drives the rotating member 52 to rotate on the support member 53. The rotating member 52 is rotatably arranged at the end of the crossbar 54, and is symmetrically arranged to be uniformly stressed. The size of the support member 53 is larger than the area where the two rotating members 52 rotate one circle. Preferably, the projection of the support member 53 on the horizontal plane is rectangular or circular. The first rotating shaft 51 passes through the center position of the support member 53.

[0045] The two inclined plates have a mounting portion 55 on one side away from each other, and the mounting portion 55 is used to be connected to the door frame 3. Preferably, a dust cover for covering the support member 53 and the rotating member 52 is installed on the mounting portion 55.

[0046] The second connecting structure 42 includes a second rotating shaft 63, a first connecting body 61 disposed at the lower part of the door panel 2, and a second connecting body 62 disposed on the support seat 69 of the door frame 3, wherein the second connecting body 62 is located below the first connecting body 61. The axis lines of the first rotating shaft 51 and the second rotating shaft 63 coincide with each other and are located in the vertical plane where the door panel 2 is located.

[0047] The lower part of the second rotating shaft 63 is connected to the second connecting body 62, and the upper part of the second rotating shaft 63 extends upward into the first connecting body 61, and the first connecting body 61 moves synchronously with the door panel 2. That is, the first connecting body 61 is fixed to the lower part of the door panel 2 and rotates with the door panel 2, while the second rotating shaft 63 and the second connecting body 62 are fixed, and the second rotating shaft 63 rotates relatively with the first connecting body 61. The second connecting structure 42 is used to support the door panel 2, and also has the function of automatically closing the door, so that the clean room door 1 can be automatically closed after it is opened.

[0048] An elastic member 64 is arranged in the first connecting body 61, and a first receiving groove for receiving part of the second rotating shaft 63 and a second receiving groove 65 for receiving the elastic member 64 are provided in the first connecting body 61, and a fixing member 66 is arranged at the end of the second receiving groove 65, and one end of the elastic member 64 acts on the second rotating shaft 63, and the other end acts on the fixing member 66. When the door panel 2 rotates to open, the first connecting body 61 rotates, and the elastic member 64 is compressed by the second rotating shaft 63, so that the elastic member 64 has an elastic restoring force, and its two ends act on the second rotating shaft 63 and the first connecting body 61 respectively, so that the door panel 2 has a tendency to close automatically, and the automatic closing is realized.

[0049] The second rotating shaft 63 has a notch 67 on one side facing the elastic member 64, and the elastic member 64 has a sleeve 68 at one end close to the second rotating shaft 63, and a part of the sleeve 68 is accommodated in the notch 67. The sleeve 68 is closed at one end close to the second rotating shaft 63. The edge of the notch 67 is arranged in an arc shape to prevent the second rotating shaft 63 from being stuck with the elastic member 64 or the sleeve 68 when the first connecting body 61 rotates.

[0050] Preferably, the notch 67 is formed by cutting off half of a portion of the second rotating shaft 63, that is, in the closed state, the surface of the notch 67 opposite to the sleeve 68 is a plane, so that the first connecting body 61 can be easily returned to the original position through the notch 67 and the elastic member 64 to achieve automatic door closing.

[0051] The end of the elastic member 64 is located in the sleeve 68 to prevent the elastic member 64 from directly contacting the second rotating shaft 63, and the elastic member 64 and the second rotating shaft 63 are stuck when the first connecting body 61 rotates. The height of the notch 67 is greater than the diameter of the sleeve 68 to prevent the sleeve 68 from driving the second rotating shaft 63 to move upward and cause it to fall off the second connecting body 62.

[0052] The second rotating shaft 63 includes a fixing portion 631 for fixing with the second connecting body 62 and a rotating portion 632 for cooperating with the elastic member 64. The notch 67 is provided on the rotating portion 632, and the rotating portion 632 is accommodated in the first accommodating groove. The fixing portion 631 is arranged in a (quasi) rectangular or polygonal shape to fix the second connecting body 62 and the second rotating shaft 63 to prevent the second rotating shaft 63 from rotating. During installation, the lower portion of the second rotating shaft 63 is inserted into the corresponding hole of the second connecting body 62 under the weight of the door panel 2.

[0053] The clean room door 1 in this embodiment has a closed state and an open state. In the closed state, the door panel 2 and the door frame 3 are located in the same vertical plane. In the open state, the projections of the door panel 2 and the door frame 3 on the horizontal plane are arranged at an angle. In the open state, the door panel 2 can realize two-way door opening and closing and automatic door closing by the dead weight of the door panel 2 under the action of the first connection structure 41 and the second connection structure 42.

[0054] The opening and closing process of the clean room door 1 in this embodiment is as follows: when the rotating member 52 is at the lowest point, the clean room door 1 is in a closed state, the door panel 2 and the door frame 3 are located in the same vertical plane, and the first rotating shaft 51 and the door panel 2 are at the lowest horizontal position. When the door needs to be opened, force acts on the door panel 2, pushing the door panel 2 to rotate, the first rotating shaft 51 rotates, the cross bar 54 rotates, and drives the rotating member 52 to rotate on the support member 53, moving from the lowest point to both sides, and the horizontal positions of the rotating member 52, the first rotating shaft 51 and the door panel 2 are raised. At this time, the projections of the door panel 2 and the door frame 3 on the horizontal plane are set at an angle, and the clean room door 1 is in an open state.

[0055] When the force acting on the door panel 2 is removed, driven by the deadweight of the door panel 2 and based on the structural setting of the support member 53, the rotating member 52 automatically moves to the lowest point of the support member 53, and drives the door panel 2 to gradually close through the first rotating shaft 51, and the clean room door 1 returns to the closed state.

[0056] Since the level of the door panel 2 will be increased during the door opening process, the clean room door 1 in this embodiment is also suitable for places with uneven ground. At the same time, the sealing strip 9 at the bottom of the clean room door 1 is thicker to ensure the sealing effect.

[0057] The clean room door 1 of this embodiment cancels the traditional door lock and other door closers, and realizes the rotation of the door panel 2 and the opening and closing of the door by setting the first connection structure 41 and the second connection structure 42. At the same time, the first connection structure 41 and the second connection structure 42 can realize the tendency of the door panel 2 to rotate and close after it is rotated and opened, so that the clean room door 1 of the present invention can be opened and closed in both directions, and can be automatically closed after opening, ensuring the sealing performance; when people enter and exit, they do not need to touch the handle 8 or other devices to open the door, and can open the door by pushing the door panel 2 with various parts of the body inside and outside the clean room. At the same time, based on the structure of the clean room door 1 in this embodiment, it can be installed near any column 31, and the installation can be selected according to the actual situation to realize the door opening to the left or right.

[0058] It should be noted that the first connecting structure and the second connecting structure in this embodiment both have the effect of enabling the door panel to close automatically after being opened. In other embodiments, the first connecting structure can be selected to have only a rotating shaft and the second connecting structure to have the effect of automatic door closing, or the second connecting structure can be selected to have only a rotating shaft and the first connecting structure to have the effect of automatic door closing, which are also within the scope of protection of the invention of this application.

[0059] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the contents of the present invention and implement them accordingly. They cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
