[0002] Purification workshops, commonly known as clean rooms or clean workshops, are specialized environments designed to control pollutants in the air, such as dust, microorganisms, chemical gases, etc. They are essential in many industries, especially in the fields of pharmaceuticals, semiconductor manufacturing, biotechnology, and high technology. Clean doors are often used in purification workshops, and the installation of clean doors requires the use of door frames.

[0003] In the traditional clean door frame, the main body of the door frame is composed of upper and lower frame beams and left and right door columns, which provide the basic support structure of the door. The sealing strip is installed on the inner side of the door frame, usually made of rubber or synthetic materials, to ensure good sealing when the door is closed. The threshold is the crossbeam at the bottom of the door frame, which helps stabilize the bottom of the door and improve the sealing. The fixings are used to fix the door frame to the wall, such as bolts or welded parts, to ensure the stability of the door frame. The decorative strips are installed on the door frame for beauty and to cover the seams.

[0004] However, traditional clean door frames often need to be assembled and welded, which requires high technical skills of welders. In addition, welding slag can easily enter the interior of the door frame during welding, and without point positioning during welding, it is easy to bend and be uneven, affecting the internal aesthetics of the door frame. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1 - Figure 2 The utility model provides an embodiment: a clean door frame connection structure, including an upper beam 1, a side beam 2 is arranged at the bottom of the upper beam 1, an upper plate 3 is fixedly connected inside the upper beam 1, and a side plate 4 is fixedly connected inside the side beam 2. Insert plates 5 are provided inside the upper plate 3 and the side plate 4, and sockets 6 are fixedly connected on the surfaces of the upper plate 3 and the side plate 4. The sockets 6 are slidably connected inside the insert plates 5, and sealing grooves 7 are provided inside the upper beam 1 and the side beam 2. A buffer component is provided inside the upper beam 1, and the buffer component is used to buffer the external impact of the upper beam 1.

[0025] Specifically, in actual production, when it is necessary to weld the upper beam 1 and the side beam 2, first insert the socket 6 on the surface of the side panel 4 into the plug plate 5 inside the upper panel 3. At this time, the socket 6 and the plug plate 5 engage with each other to achieve the connection between the upper beam 1 and the side beam 2. The protruding area formed by this connection method can prevent welding slag from splashing in. The plug-in design enables welders to better calibrate the weldments when splicing door frames, thereby improving production efficiency. From the appearance point of view, this design ensures the beauty of the interior of the door frame.

[0026] Reference Figure 3 The buffer assembly includes a pressure plate 8, multiple pressure plates 8 are fixedly connected to the inside of the upper beam 1, and the multiple pressure plates 8 are symmetrical inside the upper beam 1. The side walls of the pressure plates 8 are fixedly connected to fixed platforms 9, and multiple slides 11 are slidably connected to the inside of the pressure plates 8. A slider 15 is slidably connected to the inside of the slide 11. A spring 10 is arranged between the slide 11 and the fixed platform 9. One end of the spring 10 is fixedly connected to the inside of the fixed platform 9, and the other end of the spring 10 is fixedly connected to the inside of the slide 11. The multiple slides 11 are symmetrical to each other on the side walls of the pressure plate 8. Tension springs 14 are arranged between the slides 11. The side wall of the slider 15 is rotatably connected to a connecting rod 12, and one end of the connecting rod 12 is rotatably connected to a connecting shaft 13. The outer wall of the connecting shaft 13 is rotatably connected to another connecting rod 12, and the other connecting rod 12 is rotatably connected to the side wall of another slider 15.

[0027] Specifically, when the door frame is affected by external force, a relative impact force will quickly be generated between the pressure plates 8. During this process, the connecting rod 12 between the pressure plates 8 will rotate on the side wall of the slider 15, and its own inclination angle will continue to change with the action of external force. The driving force generated by the connecting rod 12 will drive the slider 15 to slide inside the slide 11. When the slide 11 is subjected to force, it can slide smoothly on the side wall of the pressure plate 8. Since the spring 10 is located between the fixed platform 9 and the slide 11, it has a certain tension. At the same time, the tension spring 14 exerts a pulling force on the slides 11 on both sides. Under the joint action of these two forces, the impact force exerted on the door frame can be effectively buffered after multiple transfers. In this way, the stability of the door frame under vibration or other impact forces can be greatly enhanced, ensuring that the door frame can maintain a good condition in various complex usage environments.

[0028] Working principle: When the upper beam 1 and the side beam 2 need to be welded together, first insert the socket 6 on the surface of the side plate 4 into the plug plate 5 inside the upper plate 3. At this time, the connection between the upper beam 1 and the side beam 2 can be achieved by engaging the socket 6 and the plug plate 5. The protruding area can effectively prevent welding slag from splashing in, and the plug-in design allows welders to better splice the door frame to calibrate the weldment, which improves production efficiency. The appearance ensures the beauty of the interior of the door frame. When the door frame is affected by external force, a relative impact force will be generated between the pressure plates 8. At this time, the connecting rod 12 between the pressure plates 8 will rotate on the side wall of the slider 15 and change its own inclination angle. The driving force of the connecting rod 12 drives the slider 15 to slide inside the slide 11. After the slide 11 is subjected to force, it can slide on the side wall of the pressure plate 8. Due to the tension of the spring 10 between the fixed platform 9 and the slide 11 and the tension of the tension spring 14 on the slides 11 on both sides, this impact force is buffered after being transferred multiple times to enhance the stability of the door frame under vibration or other impact forces.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
