Detailed Implementation

[0021] This utility model is as follows Figures 1 to 5 As shown, a multi-functional door for cleanrooms includes a mounting frame 10, a first lifting door 20, a first lifting drive mechanism 30, a first guide mechanism 40, a second lifting door 50, a second lifting drive mechanism 60, and a second guide mechanism 70, wherein:

[0022] The first lifting drive mechanism 30 and the second lifting drive mechanism 60 are distributed in parallel on the mounting frame 10. The first lifting door 20 is installed at the output end of the first lifting drive mechanism 30, and the second lifting door 50 is installed at the output end of the second lifting drive mechanism 60. The first lifting door 20 and the second lifting door 50 are located side by side on the mounting frame 10 in a liftable manner. The first lifting door 20 is connected to the first guide mechanism 40, and the second lifting door 50 is connected to the second guide mechanism 70.

[0023] When it is necessary to open or close the multi-functional door, the first lifting drive mechanism 30 and the second lifting drive mechanism 60 are activated. The first lifting drive mechanism 30 drives the first lifting door 20 to rise and fall, and the second lifting drive mechanism 60 drives the second lifting door 50 to rise and fall. During the lifting process, the first guide mechanism 40 guides the first lifting door 20, and the second guide mechanism 70 guides the second lifting door 50.

[0024] The first lifting drive mechanism 30 and the second lifting drive mechanism 60 are distributed in parallel on the mounting frame 10, respectively driving the first lifting door 20 and the second lifting door 50. This allows the two doors to rise and fall synchronously, realizing the overall opening and closing of the door; or they can be controlled independently according to actual needs, flexibly adjusting the size and method of opening the door, improving the convenience of entering and exiting the cleanroom. The first lifting door 20 and the second lifting door 50 are located side by side on the mounting frame 10, which makes full use of space and prevents the door from occupying too much lateral space when opening, making it suitable for cleanroom environments with limited space. The first lifting door 20 is connected to the first guide mechanism 40, and the second lifting door 50 is connected to the second guide mechanism 70, ensuring that the first lifting door 20 and the second lifting door 50 move along a predetermined trajectory during the lifting process, avoiding door shaking or deviation, ensuring that the lifting process of the first lifting door 20 and the second lifting door 50 is smooth, and reducing the impact on the airflow and environment in the cleanroom.

[0025] The first lifting drive mechanism 30 and the second lifting drive mechanism 60 both include a lifting drive motor 31, a gear 32 and a rack 33. The lifting drive motor 31 is mounted on the mounting frame 10, the gear 32 is sleeved on the output end of the lifting drive motor 31, and the rack 33 meshes with the gear 32. The rack 33 of the first lifting drive mechanism 30 is fastened to the first lifting door 20, and the rack 33 of the second lifting drive mechanism 60 is fastened to the second lifting door 50.

[0026] The door is raised and lowered using a gear 32 and rack 33 transmission method. The lifting drive motor 31 drives the gear 32 to rotate, and the gear 32 meshes with the rack 33 to achieve the raising and lowering of the door. This transmission method has the characteristics of high transmission accuracy, which can accurately control the door's raising and lowering height and speed, meeting the requirements of cleanrooms for the accuracy of door opening and closing.

[0027] The first guide mechanism 40 and the second guide mechanism 70 both include a guide rod 41 and a slider 42. The guide rod 41 is vertically arranged on the mounting frame 10, and the slider 42 is slidably sleeved on the guide rod 41. The slider of the first guide mechanism 40 is fastened to the first lifting door 20, and the slider of the second guide mechanism 70 is fastened to the second lifting door 50.

[0028] The guide rod 41 is vertically mounted on the mounting frame 10, and the slider 42 is slidably fitted onto the guide rod 41. This structure provides smooth guidance for the lifting and lowering of the first lifting door 20 and the second lifting door 50. The slider 42 slides on the guide rod 41, reducing friction between the first and second lifting doors 20 and 50 and the mounting frame 10, making the lifting and lowering of the first and second lifting doors 20 and 50 easier and smoother, while also reducing noise. The first guide mechanism 40 and the second guide mechanism 70 enhance the stability of the first and second lifting doors 20 and 50 during the lifting process, preventing them from tilting or swaying due to external forces, thus ensuring the normal use and safety of the first and second lifting doors 20 and 50.

[0029] The slider 42 is vertically through-featured with a groove 421 that matches the guide rod 41; a first connecting block 43 is provided between the slider 42 of the first guide mechanism 40 and the first lifting door 20, and a second connecting block is provided between the slider 42 of the second guide mechanism 70 and the second lifting door 50.

[0030] The slider 42 is vertically connected to the guide rod 41 by a groove 421 that matches the guide rod 41, ensuring that the slider 42 can slide accurately on the guide rod 41, thereby further improving the accuracy and stability of the guide.

[0031] An observation window 51 is provided at the middle position of the first lifting door 20 and the middle position of the second lifting door 50. The observation window is made of sealed glass. An upper mounting seat 411 is provided at the upper end of the guide rod 41, and a lower mounting seat 412 is provided at the lower end of the guide rod 41. The upper mounting seat 411 is detachably located on the upper side of the mounting frame 10, and the lower mounting seat 412 is detachably located on the lower side of the mounting frame 10.

[0032] An observation window 51 is provided between the first lifting door 20 and the second lifting door 50, which allows staff to observe the situation inside the clean room without opening the door, reducing the number of times the door is opened, reducing the impact of outside air on the clean room environment, and also improving work efficiency.

[0033] The lower surface of the upper mounting base 411 and the upper surface of the lower mounting base 412 are both flat. The upper and lower surfaces of the slider 42 are also flat. The upper surface of the slider 42 can rise to abut against the lower surface of the upper mounting base 411, and the lower surface of the slider 42 can descend to abut against the upper surface of the lower mounting base 412. This planar contact method can play a buffering role, reduce the impact force between the slider 42 and the mounting base, and extend the service life of the equipment.

[0034] The lower surface of the upper mounting base 411 forms a first limiting surface 4111 for limiting the upward movement of the slider 42, and the upper surface of the lower mounting base 412 forms a second limiting surface 4121 for limiting the downward movement of the slider 42. By using the first limiting surface 4111 and the second limiting surface 4121, the first lifting door 20 and the second lifting door 50 can be effectively prevented from exceeding the normal lifting range, protecting the first lifting door 20 and the second lifting door 50 from damage, and improving the safety and reliability of the equipment.

[0035] The usage method and principle of this type of multifunctional door used in cleanrooms are as follows:

[0036] When it is necessary to open or close the multi-functional door, the first lifting drive mechanism and the second lifting drive mechanism are activated. The first lifting drive mechanism drives the first lifting door to rise and fall, and the second lifting drive mechanism drives the second lifting door to rise and fall. During the lifting process, the first guide mechanism guides the first lifting door, and the second guide mechanism guides the second lifting door.

[0037] The key design feature of this invention is that the first lifting drive mechanism and the second lifting drive mechanism drive the first lifting door and the second lifting door respectively. This allows the two doors to rise and fall synchronously, realizing the overall opening and closing of the door; they can also be controlled independently according to actual needs, flexibly adjusting the size and method of opening the door, thus improving the convenience of entering and exiting the clean room. The first lifting door is connected to the first guide mechanism, and the second lifting door is connected to the second guide mechanism, ensuring that the lifting process of the first and second lifting doors is smooth and reducing the impact on the airflow and environment in the clean room.

[0038] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
