[0017] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings and embodiments. Obviously, the embodiments described 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 are within the scope of protection of the present invention.

[0018] like Figures 1 to 4 As shown, an armored thermal resistor cold processing sealing device includes a mounting frame 1. The mounting frame 1 can be any table or load-bearing object. When placing the cold processing box 2, it needs to be placed on the edge of the mounting frame 1 to facilitate subsequent fixed installation operations on the mounting frame 1.

[0019] A cold working box 2 is provided on the top of the mounting frame 1 .

[0020] The left and right sides and rear of the cold working box 2 are provided with limiting fixing components for fixing the cold working box 2. When the size of the mounting frame 1 is large, the cold working box 2 can be easily fixed at the corners of the mounting frame 1.

[0021] A sealing groove 3 is formed inside the cold working box 2 . A sealing strip 402 is fixedly connected to the outer surface of the connecting plate 401 , and the outer surface of the sealing strip 402 contacts the inner wall of the sealing groove 3 .

[0022] The inner wall of the sealing groove 3 is also provided with a rubber layer. The sealing groove 3 cooperates with the sealing strip 402 to form a closed channel, thereby achieving a sealing effect on the cold processing box 2.

[0023] A sealing assembly 4 is provided inside the cold working box 2 .

[0024] The sealing assembly 4 includes a connecting plate 401 plugged into the inner wall of the sealing groove 3 , and a sealing door 403 is fixedly connected to the outer surface of the connecting plate 401 .

[0025] The sealed door 403 can be made of transparent high-temperature resistant tempered glass, which makes it easy to observe the state of the armored thermal resistor inside the cold working box 2 through the sealed door 403.

[0026] A handle 404 is fixedly connected to the outer surface of the sealing door 403 .

[0027] Two handles 404 are provided to facilitate the movement of the entire sealing assembly 4, so as to facilitate the sealing assembly 4 to perform sealing operations on the cold processing box 2 and release the sealing state.

[0028] A clamping strip 5 is fixedly connected to the outer surface of the cold working box 2 , and a clamping slot 8 is provided inside the connecting frame 7 , and the clamping slot 8 and the clamping strip 5 slide.

[0029] The clamping strip 5 and the clamping slot 8 are both arranged in a T-shape, and the two can be easily engaged with each other to limit the position, thereby achieving a limiting effect on the connecting frame 7.

[0030] A limit hole 6 is defined inside the card strip 5 .

[0031] The outer surface of the clamping strip 5 is clamped with a connecting frame 7 .

[0032] The overall shape of the connecting frame 7 is U-shaped, and a layer of protective pad is provided on the inner wall of the connecting frame 7, which can effectively protect the edge of the mounting frame 1.

[0033] A limiting mechanism 9 is provided on the outer side of the connecting frame 7 .

[0034] The limiting mechanism 9 includes a limiting rod 901 slidably connected to the inner wall of the connecting frame 7 , and a pull tab 902 is fixedly connected to the outer surface of the limiting rod 901 .

[0035] An elastic member 903 is sleeved on the outer surface of the limiting insertion rod 901 , one end of the elastic member 903 is fixedly connected to the outer surface of the pull tab 902 , and the other end of the elastic member 903 is fixedly connected to the outer surface of the connecting frame 7 .

[0036] The elastic member 903 is made of a spring. By pulling the pull tab 902, the limiting rod 901 is moved away from the card strip 5, so that the limiting rod 901 is pulled out of the limiting hole 6. At the same time, the pull tab 902 will stretch the elastic member 903, thereby causing the elastic member 903 to deform and store a certain amount of elastic potential energy. When the pull tab 902 is released, the elastic member 903 will release the elastic potential energy, thereby driving the pull tab 902 and the limiting rod 901 to move in the opposite direction, so that the limiting rod 901 is reinserted into the limiting hole 6, thereby achieving a rapid reset effect of the limiting rod 901.

[0037] A fixing mechanism 10 is provided below the connecting frame 7 .

[0038] The fixing mechanism 10 includes an adjusting screw 101 threadedly connected to the inner wall of the connecting frame 7 , and one end of the adjusting screw 101 is fixedly connected to a knob 102 .

[0039] The outer surface of the knob 102 is provided with anti-slip grooves, which can increase the friction with the operator's fingers, thereby making it easier to save effort when turning the knob 102.

[0040] The other end of the adjusting screw 101 is fixedly connected to a limiting plate 103 .

[0041] The outer surface of the adjusting screw 101 is rotatably connected to a top block 104 , and the outer surface of the top block 104 contacts the bottom surface of the mounting bracket 1 .

[0042] A protective pad is provided on the top of the top block 104 , which can provide protection for the bottom of the mounting frame 1 when the mounting frame 1 is pressed tightly, thereby preventing the outer surface of the mounting frame 1 from being damaged.

[0043] A movable groove 105 is defined inside the top block 104 , and the inner wall of the movable groove 105 rotates with the outer surface of the limiting piece 103 .

[0044] Working principle: When the present invention is in use, if the sealing device needs to be disassembled, the knob 102 needs to be rotated first. At this time, the knob 102 will drive the adjusting screw 101 and the limiting piece 103 to rotate accordingly, and then the adjusting screw 101 drives the knob 102 and the limiting piece 103 to move downward along with the spiral. At the same time, the limiting piece 103 will drive the top block 104 to move downward along, so that the top of the top block 104 is separated from the bottom of the mounting frame 1, thereby releasing the fixed limit between the connecting frame 7 and the mounting frame 1, and then it is necessary to pull the pull tab 902 to drive the limiting rod 901 away The card strip 5 moves, so that the limit rod 901 is pulled out of the limit hole 6, and the connecting frame 7 is pushed forward or backward. At this time, the connecting frame 7 will drive the limit mechanism 9 and the fixing mechanism 10 to move accordingly, and then the connecting frame 7 will be removed from the card strip 5. At this time, the cold working box 2 can be removed from the mounting frame 1. When the cold working box 2 needs to be installed, only the direction operation is required, that is, first the cold working box 2 needs to be placed on the mounting frame 1, and then the card slot 8 needs to be aligned with the card strip 5. At the same time, the pull tab 902 needs to be pulled to drive the limit rod 901 to move outward. At this time, the connecting frame 7 is pushed horizontally in the front and rear directions along the edge of the mounting frame 1 to move the connecting frame 7 so that the card strip 5 is stuck in the card slot 8. After it is fully stuck, the pull tab 902 can be released. At this time, the stretched elastic member 903 will drive the pull tab 902 and the limit plug 901 to reset, that is, drive the pull tab 902 and the limit plug 901 to move close to the mounting frame 1 so that the limit plug 901 can be inserted into the limit plug hole 6. Then you need to rotate the knob 102. At this time, the knob 102 will drive the adjusting screw 101 and the limit piece 103 to rotate accordingly, so that the adjusting screw 101 can The movable knob 102 and the limiting piece 103 follow the upward movement of the spiral, and the limiting piece 103 will drive the top block 104 to follow the upward movement, so that the top of the top block 104 can be tightly pressed against the bottom of the mounting frame 1, so that it is convenient to quickly fix the mounting frame 1 and the connecting frame 7. Through the cooperation between the card strip 5, the connecting frame 7, the limiting mechanism 9 and the fixing mechanism 10, it is convenient to quickly fix and install the upper mounting frame 1, so that the entire sealing device can be disassembled and assembled. The disassembly and assembly process is relatively simple and fast, thereby improving the overall operating efficiency of the sealing device.
