[0020] 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.
[0021] See also Figure 1-4 In this embodiment, a closed door with a double-pass sealing four-side compression and locking system includes a door frame 1, a sealed door body 3 and a fixed box 6. A clamping mechanism is arranged on the outside of the sealed door body 3. Sealing plates 2 are fixedly installed on the left and right side walls of the inner cavity of the door frame 1. The sealed door bodies 3 are rotatably installed on the front sides of the two sealing plates 2. A handle 4 is fixedly installed on the front side of the sealed door body 3. A password lock 5 is fixedly installed on the front side of the sealed door body 3. The fixed box 6 is fixedly installed on the inner top wall of the door frame 1.
[0022] Among them, the number of fixed boxes 6 and the number of clamping mechanisms are both set to two, and the two fixed boxes 6 and the two clamping mechanisms are respectively located at the top and bottom of the sealing door body 3, which can play the role of clamping the top and bottom of the sealing door body 3, thereby making the sealing effect better.
[0023] The electrical components in the present invention are all electrically connected to an external main controller, and the main controller can be a conventional known device for controlling a computer, etc. The circuits and controls involved in the present invention are all prior art and will not be elaborated on here.
[0024] Among them, fixing rods are fixedly installed on the opposite sides of the two fixed boxes 6, and the opposite sides of the two fixing rods are fixedly connected to the inner top wall and the inner bottom wall of the door frame 1 respectively, so as to achieve the purpose of supporting the fixed box 6, so that the fixed box 6 will not shake during use and can remain stable.
[0025] Specifically, by providing a clamping mechanism, the sealing door body 3 can be compressed, so that the sealing door body 3 is better sealed when in use, thereby reducing damage to personnel. By providing a sealing plate 2, its function is to seal the gap from the left and right sides, so that it will not be airtight after closing the sealing door body 3.
[0026] like Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, the clamping mechanism includes a motor 71 fixedly mounted on the left side wall of the inner cavity of the fixed box 6, the output shaft of the motor 71 is fixedly mounted with a worm 72 through a coupling, a support rod 73 is rotatably mounted on the inner top wall of the fixed box 6, a worm wheel 74 is fixedly mounted on the outer surface of the support rod 73, the outer surface of the worm 72 is meshed with the outer surface of the worm wheel 74, a driving gear 75 is fixedly mounted on the outer surface of the support rod 73, a screw rod 76 is rotatably mounted between the inner top wall and the inner bottom wall of the fixed box 6, a driven gear 77 is fixedly mounted on the outer surface of the screw rod 76, the outer surface of the driving gear 75 is meshed with the outer surface of the driven gear 77, a connecting block 78 is threadedly connected to the outer surface of the screw rod 76, and a pressure plate 79 with one end penetrating through and extending to the outside of the fixed box 6 is fixedly mounted on the right side of the connecting block 78.
[0027] Among them, the inner bottom walls of the two fixed boxes 6 are fixedly installed with limit plates, and the right sides of the two limit plates are provided with sliding grooves. The left sides of the two connecting blocks 78 are fixedly installed with sliders, and the outer surfaces of the sliders are slidably connected to the inner walls of the sliding grooves. When they are in action, they can limit the two connecting blocks 78, so that the two connecting blocks 78 can only move up and down when in use.
[0028] The two sealing plates 2 are both located at the rear side of the pressure plate 79 , so that when the pressure plate 79 presses the sealing door body 3 , the sealing plates 2 will not affect it.
[0029] It should be added that the two motors 71 are controlled by the same controller, so that the two motors 71 can be operated simultaneously, and the threads on the outer surfaces of the two screw rods 76 are in opposite directions.
[0030] Among them, a through groove is opened on the inner bottom wall of the fixed box 6, and the size of the through groove is adapted to the size of the pressure plate 79, so as to facilitate the removal of the pressure plate 79 from the fixed box 6, so that the pressure plate 79 can press the sealing door body 3.
[0031] Specifically, by providing a motor 71, a worm 72, a support rod 73, a worm wheel 74, a driving gear 75, a screw 76, a driven gear 77, a connecting block 78 and a pressure plate 79, the sealing door body 3 can be squeezed, so that the sealing door body 3 is better sealed when in use, and the sealing door body 3 can also be made safer after closing, thereby improving the sealing and safety of the closed door with a double-pass sealing four-side clamping and locking system.
[0032] The working principle of the above embodiment is:
[0033] When it is necessary to tighten the sealing door body 3, the sealing door body 3 needs to be closed first, and then the two motors 71 are started at the same time, so that the two motors 71 respectively drive the two worm gears 72 to rotate clockwise at the same time, and the two worm gears 72 respectively drive the two worm wheels 74 to rotate clockwise at the same time, and the two worm wheels 74 respectively drive the two support rods 73 to rotate clockwise at the same time, and the two support rods 73 respectively drive the two driving gears 75 to rotate clockwise at the same time, and the two driving gears 75 respectively drive the two driven gears 77 to rotate clockwise at the same time, and the two driven gears 77 respectively drive the two screw rods 76 to rotate clockwise at the same time, and the two screw rods 76 respectively drive the two connecting blocks 78 to move to the opposite side at the same time, and the two connecting blocks 78 respectively drive the two pressing plates 79 to move to the opposite side at the same time, and when the two pressing plates 79 move to the sealing door body 3 to be pressed, the two motors 71 are turned off at the same time, thereby completing the pressing work of the sealing door body 3.
[0034] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
[0035] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
