[0001] The invention relates to the technical field of explosion-proof doors, in particular to a high-sealing safety explosion-proof door. Background Art

[0002] Explosion-proof doors are explosion-proof protective equipment designed to resist accidental explosions in equipment outside industrial buildings, ensure the safety of personnel and the integrity of equipment inside industrial buildings, protect against the impact of explosion shock waves and effectively prevent the continuation of explosion hazards.

[0003] Most of the existing explosion-proof doors are connected by a rotating shaft and opened by rotating. The strength of the rotating shaft is much smaller than the strength of the door body. This means that when the explosion-proof door is subjected to impact force, the pressure of the impact force mainly acts on the rotating shaft, causing the explosion-proof door to collapse.

[0004] For example, in the "A Highly Sealed Safety Explosion-Proof Door for Electromagnetic Starters for Mines" published in Chinese Patent Publication No. CN 218644163 U, the door body is connected by a hinge shaft. No matter how strong the door body is, the hinge shaft is a weak point, and the collapse problem described above will occur.

[0005] To this end, the present application proposes a highly sealed safety explosion-proof door to solve the problem that the connection of the explosion-proof door is easily damaged as mentioned in the above background technology. Summary of the invention

At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the present invention. Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0047] like Figure 1-Figure 12 As shown, the present invention provides a high-sealing safety explosion-proof door, including a supporting mechanism 1, a fixed door assembly 2 and a movable door assembly 3.

[0048] The supporting mechanism 1 includes an outer frame 101 , and a track groove 102 is circulated on the inner wall of the outer frame 101 . The track groove 102 supports the movable door assembly 3 and enables the movable door assembly 3 to move along a predetermined track, so as to improve the stability of the movable door assembly 3 .

[0049] The fixed door assembly 2 includes a fixed door body 201, which is installed on one side of the inner part of the outer frame 101. The outer frame 101 and the fixed door body 201 form a whole, thereby ensuring the strength of the fixed door body 201 to prevent the fixed door body 201 from tipping over after being impacted, thereby improving safety. The side of the fixed door body 201 is provided with a receiving groove 202 extending into the inner part of the fixed door body 201, so that the movable door assembly 3 is limited by the cooperation of the receiving groove 202 and the track groove 102.

[0050] The movable door assembly 3 includes a movable movable door 301, and both upper and lower sides of the movable movable door 301 extend into the interior of the track groove 102, so that the movable movable door 301 is limited and supported by the track groove 102, so that the movable movable door 301 moves along the track of the track groove 102. Both upper and lower sides of the movable movable door 301 are installed with movable slide rails 302. When the movable movable door 301 is pushed, the movable slide rails 302 can convert hard friction into rolling friction, thereby improving the flexibility of the movable movable door 301, so that the movable movable door 301 can be pushed by manpower.

[0051] The front and rear surfaces of the fixed door body 201 are flush with the front and rear surfaces of the outer frame 101. The track groove 102 and the storage groove 202 have the same width, so as to ensure that after the movable door 301 is installed, the front and rear surfaces of the movable door 301 can fit with the front and rear inner walls of the track groove 102 and the storage groove 202 respectively, thereby improving the sealing performance.

[0052] The outer frame 101 is pre-buried in the ground and the wall, and the strength of the entire explosion-proof door is improved by the strength of the concrete wall. When installed, the lower edge of the outer frame 101 is preferably slightly protruding from the ground to reduce the possibility of dust entering the track groove 102. After the movable door 301 is closed, the four sides are supported by the outer frame 101 and the fixed door body 201, so that compared with the transmission shaft support, the strength is higher and the ability to resist explosion impact is stronger.

[0053] In some embodiments, the upper and lower parts of the front and rear surfaces of the movable sliding door 301 of the present invention are provided with sealing strips 303, and the inner wall of the track groove 102 is provided with a sealing groove 103 adapted to the sealing strip 303, and the sealing strip 303 can slide inside the sealing groove 103. The track groove 102 is sealed by the cooperation of the sealing strip 303 and the sealing groove 103, so as to prevent the harmful gas from leaking through the movable slide rail 302, thereby improving the sealing performance of the explosion-proof door.

[0054] In some embodiments, a cushioning rubber pad 304 is provided on both sides of the movable movable door 301 of the present invention, so as to achieve a cushioning effect when the movable movable door 301 is opened and closed, and is used to protect the outer frame 101 and the movable movable door 301. A cavity is provided inside the cushioning rubber pad 304, and air punching holes 305 are provided on the upper and lower surfaces of the cushioning rubber pad 304. When the movable movable door 301 is closed or opened to the maximum, the cushioning rubber pad 304 will be compressed and squeezed into the cavity, so that the gas inside the cushioning rubber pad 304 is discharged through the air punching holes 305, reducing the rebound force of the cushioning rubber pad 304, and preventing the movable movable door 301 from opening or closing in place. At the same time, the airflow generated by the pressure of the cushioning rubber pad 304 can clean the floating dust inside the track groove 102.

[0055] In some embodiments, both sides of the bottom of the movable sliding door 301 of the present invention are provided with dust pushing components 306, and the bottom of the dust pushing components 306 is in contact with the inner bottom of the bottom track groove 102. Because the front and rear sides of the movable slide rail 302 overlap the inner wall of the track groove 102, and the left and right sides of the movable slide rail 302 are open. Therefore, dust easily enters the interior of the movable slide rail 302, causing the movable slide rail 302 to be inflexible in rotation. Therefore, the dust pushing components 306 are provided to block the two ends of the movable slide rail 302. At the same time, when the movable sliding door 301 is pushed, the dust pushing components 306 can also push the accumulated dust in the track groove 102 to the two sides of the track groove 102, so as to avoid the accumulated dust interfering with the movement of the movable slide rail 302.

[0056] It should be noted that the bottom of the side of the dust pushing component 306 of the present invention is a beveled blade, so that the dust cleaning ability of the end of the dust pushing component 306 is stronger, and when pushing the movable movable door 301, the force application point of the beveled blade is more concentrated, so that the movable slide rail 302 can move and push dust more easily in the track groove 102.

[0057] In some embodiments, the movable rail 302 of the present invention includes two parallel rails and a plurality of rollers installed in the rails, and each roller is close to each other. The pressure on the rail and the pressure on a single roller are reduced by reducing the gap between the rollers and increasing the number of rollers. The weight of the solid movable door 301 is prevented from bending the movable rail 302, and when the movable door 301 is impacted, the deformation resistance of the movable rail 302 and the flexibility of the movable rail 302 are improved.

[0058] In some embodiments, a locking mechanism 4 is provided on the movable door 301 of the present invention. The locking mechanism 4 includes a hand valve 401 protruding from the surface of the movable door 301 and a lock buckle 402 installed inside the movable door 301. The lock buckle 402 can be adjusted to extend and contract to cooperate with the inner wall of the track groove 102 by rotating the hand valve 401, so as to limit the movable door 301. When the hand valve 401 is rotated, the hand valve 401 drives the connecting rod or the worm to rotate, so that the lock buckle 402 can be extended and contracted to lock the movable door 301 or unlock the movable door 301. The locking mechanism 4 is a prior art, please refer to the existing explosion-proof door, and its specific structure and locking principle will not be described in detail.

[0059] In some embodiments, the side of the fixed door body 201 of the present invention is provided with a life-support pipeline 203 and a sewage pipeline 204 pre-buried in the wall, and the outer surface of one side of the fixed door body 201 is provided with a ventilation hole 205, and the ventilation hole 205 is connected with the life-support pipeline 203 and the sewage pipeline 204. When people are stranded in a confined space, such as an air-raid shelter, it is not possible to effectively provide life support for the stranded people only through the ventilation channel provided. Therefore, the life-support pipeline 203 is provided to extend from the wall to the outside world, and oxygen and clean water are transported to the confined space through the life-support pipeline 203, which can effectively maintain the vital signs of the stranded people and improve the success rate of rescue. Harmful gases can be extracted and centrally treated through the sewage pipeline 204 to avoid the discharge of harmful gases through the ventilation channel and cause large-scale environmental pollution. The wall can also effectively ensure that the life-support pipeline 203 and the life-support pipeline 203 will not be affected by the impact of the explosion.

[0060] In some embodiments, a check mechanism 5 is provided inside the connection between the life-support pipeline 203 and the fixed door body 201 of the present invention to prevent harmful gases from flowing back through the life-support pipeline 203 and causing pollution to the life-support system.

[0061] Specifically, the non-return mechanism 5 includes a blocking rib 501, a sealing ring 502, a sealing component 503 and an elastic member 504. A gap is left between the blocking rib 501 and the sealing ring 502 to form a movable space for the sealing component 503 and a compressed space for the elastic member 504. The blocking rib 501 is a support body with a gap, and the sealing ring 502 is a support body with a concave groove. The sealing component 503 and the elastic member 504 are both arranged between the blocking rib 501 and the sealing ring 502. The elastic member 504 is used to apply elastic force to the sealing component 503 so that the sealing component 503 can seal the sealing ring 502 when no external force is applied.

[0062] Specifically, the sealing component 503 includes a sealing plug matched with the sealing ring 502, a force plate and a connection between the sealing plug and the force plate. When the sealing component 503 is sealed, the elastic member 504 applies force to the force plate, so that the sealing plug and the force plate overlap the sealing ring 502 and the blocking rib 501 to form a seal. When the force plate is subjected to thrust, the force plate compresses the elastic member 504, so that a gap is left between the sealing ring 502 and the sealing plug for gas or liquid to pass through.

[0063] In some embodiments, the outer surface of the fixed door body 201 of the present invention is provided with a plurality of reinforcing ribs 206, and gaps are left between each reinforcing rib 206. When the fixed door body 201 is subjected to impact force, the reinforcing ribs 206 can effectively improve the strength of the fixed door body 201, and cooperate with the thickness of the wall surface of the fixed door body 201 itself to reduce the deformation amplitude of the fixed door body 201. It is used to prevent the fixed door body 201 from being excessively deformed, which makes the movable door 301 difficult to open.

[0064] In summary, the high-sealing safety explosion-proof door of the present invention is embedded in the concrete floor and wall by setting an outer frame 101 to improve the firmness during installation. At the same time, the fixed door body 201 is installed integrally with the outer frame 101, and the movable door 301 is limited by the track groove 102 and the storage groove 202. Therefore, after the movable door 301 is closed, the upper, lower and one side of the movable door 301 are supported by the outer frame 101, and the other side of the movable door 301 is supported by the fixed door body 201, thereby achieving the effect of improving the impact resistance of the explosion-proof door.

[0065] The present invention arranges a plurality of rollers close to each other to cooperate with the track bar to prevent the weight of the solid movable door 301 from bending the movable slide rail 302, and improves the deformation resistance of the movable slide rail 302 when the movable door 301 is impacted, thereby improving the flexibility of the movable slide rail 302.

[0066] The present invention arranges dust pushing components 306 on both sides of the movable slide rail 302 at the bottom of the movable movable door 301, so that when the movable movable door 301 is pushed to move, the dust pushing components 306 can push the dust accumulated in the track groove 102 to prevent the dust from being stuck between the movable slide rails 302, so that the movable movable door 301 can be pushed relatively easily.

[0067] The present invention provides reinforcing ribs 206 on the outer surface of the fixed door body 201 to enhance the anti-deformation capability of the fixed door body 201, thereby reducing the deformation amplitude of the fixed door body 201 when the fixed door body 201 is subjected to impact force, thereby preventing the movable door 301 from being unable to open due to excessive deformation of the fixed door body 201.

[0068] The present invention arranges a life-support pipeline 203 and a sewage pipeline 204 on the side of the fixed door body 201, and arranges a ventilation hole 205 on the fixed door body 201, and makes the ventilation hole 205 on the safe side. When the stranded personnel are blocked in the enclosed space, oxygen and clean water can be input into the enclosed space through the life-support pipeline 203, and harmful gases can be discharged through the sewage pipeline 204, so as to ensure the safety of the stranded personnel.

[0069] The present invention provides a sealing strip 303 on the outer surface of the movable door 301, and makes the sealing strip 303 cooperate with the sealing groove 103 to seal the mouth of the track groove 102, thereby preventing harmful substances from leaking from the bottom of the movable door 301, thereby achieving the effect of improving safety.

[0070] Therefore, the present invention effectively overcomes various shortcomings in the prior art and has high industrial utilization value.

[0071] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
