Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air-tight door equipment, in particular to an air-tight automatic door with reinforced buffer energy absorption and power-assisted starting function. BACKGROUND

[0002] The air-tight door is generally used in hospitals, food factories, industrial plants and other places with high requirements for sound insulation, heat insulation and air-tightness. The air-tight door uses a small-size high-power DC brushless motor, which can run for a long time without failure even if it is frequently opened and closed.

[0003] A medical operating room air-tight automatic door is disclosed in the utility model patent with publication number CN214035376U, which comprises a machine case and a door frame welded to the bottom outer wall of the machine case. Concave grooves are formed on the inner walls of the two sides and the bottom of the door frame, and a limiting plate is welded to the inner walls on both sides of the top end of the concave groove at the bottom of the door frame. A first sealing frame in "U" shape is embedded in the inner walls of the concave grooves on both sides of the door frame. Two sliding blocks are slidingly installed in the concave groove at the bottom of the door frame, and a connecting frame is welded to the outer walls of the bottom of each sliding block. A roller is connected to the outer wall on one side of the two connecting frames through a bearing. A door panel is arranged in the door frame, and the door panel is welded to the outer walls of the top ends of the two sliding blocks at both ends of the bottom of the door panel.

[0004] Although the above-mentioned air-tight door can perform air-tight closing operation, it has insufficient buffer performance at the closing position of the air-tight automatic door. If the staff is present at the closing position when the air-tight door is closing, the closing speed is too fast and may cause injury to the staff. In addition, the air-tight door is relatively slow to open due to its large weight, which reduces the convenience of opening the air-tight door. Therefore, an air-tight automatic door with reinforced buffer energy absorption and power-assisted starting function is needed to solve the above-mentioned problems. SUMMARY

[0005] The present application aims to provide an air-tight automatic door with reinforced buffer energy absorption and power-assisted starting function to solve the problems mentioned in the background.

Three groups of connecting windows are symmetrically and equidistantly arranged on the inner end surface of the gas-tight door housing, and a sliding rail sliding groove is formed at the center of the lower end surface of the gas-tight door housing. A support sliding groove is formed at the center of the upper end surface of the gas-tight door housing, and a connecting toothed plate is fixedly arranged on the inner end surface side wall of the support sliding groove. The gas-tight door housing is symmetrically provided with a gas pressure control module on the inner end surface, and a connecting handle is arranged at the front part of the side end surface of the gas-tight door housing. A positioning sliding plate is arranged at the front part of the upper end surface of the gas-tight door housing, and a guiding sliding groove is formed at the center of the inner end surface of the positioning sliding plate.

[0030] Embodiment 1

[0031] Please refer to Figures 1-6 The present application provides an embodiment: a reinforced buffer energy absorption and power-assisted starting function air-tight automatic door, comprising a guide buffer assembly 1, a positioning slot 2, a sealing assembly 3 and a connecting card 4,

[0032] The side end face of the guide buffering assembly 1 is symmetrically provided with a connecting plate 4 for connection, and a positioning slot 2 is uniformly and equidistantly arranged on the side end face of the connecting plate 4 near the top. The inner end face of the guide buffering assembly 1 is slidably connected with a sealing assembly 3,

[0033] The guide buffering assembly 1 comprises a reduction motor 11, a fixed gear 12, a motor clamping seat 13, a guide sliding shaft 14, a sealing plate 15, a connecting guide rail 16, a first buffering spring 17, a second buffering spring 18, a third buffering spring 19 and a support guide shaft 110.

[0034] The inner end face side of the connecting guide rail 16 is uniformly and equidistantly provided with three groups of guide sliding shafts 14, and the front end face of the connecting guide rail 16 is fixedly installed with the motor clamping seat 13. The inner end face of the motor clamping seat 13 is fixedly provided with the reduction motor 11, and the lower end face center of the reduction motor 11 is fixedly installed with the fixed gear 12. The inner end face of the connecting guide rail 16 is sequentially fixedly provided with the first buffering spring 17, the second buffering spring 18 and the third buffering spring 19 from bottom to top. The center of the rear end face of the connecting guide rail 16 is fixedly installed with the sealing plate 15, and the center of the inner end face of the connecting guide rail 16 is fixedly installed with the support guide shaft 110.

[0035] The sealing assembly 3 comprises a connecting handle 31, a limiting sliding block 32, a limiting spring 33, a positioning sliding plate 34, a guide sliding groove 35, a connecting tooth plate 36, a support sliding groove 37, an air-tight door shell 38, a sliding rail sliding groove 39, a connecting window 310, an air pressure control module 311 and an air pressure sensor 312. The inner end face of the air-tight door shell 38 is uniformly and equidistantly provided with three groups of connecting windows 310, and the lower end face center of the air-tight door shell 38 is provided with the sliding rail sliding groove 39. The center of the upper end face of the air-tight door shell 38 is provided with the support sliding groove 37, and the inner end face side wall of the support sliding groove 37 is fixedly provided with the connecting tooth plate 36. The inner end face of the air-tight door shell 38 is symmetrically provided with the air pressure control module 311, and the side end face near the front part of the air-tight door shell 38 is provided with the connecting handle 31. The upper end face near the front end of the air-tight door shell 38 is provided with the positioning sliding plate 34, and the inner end face center of the positioning sliding plate 34 is provided with the guide sliding groove 35. The side end face of the positioning sliding plate 34 is uniformly and equidistantly provided with three groups of limiting sliding blocks 32, and the front end face of the positioning sliding plate 34 is fixedly installed with the limiting spring 33 opposite to the guide sliding groove 35. The side end face of the air-tight door shell 38 away from the connecting handle 31 is symmetrically provided with the air pressure sensor 312.

[0036] The side end face of the fixed gear 12 is meshingly connected with the connecting tooth plate 36, and the side wall of the fixed gear 12 does not contact with the side wall of the support sliding groove 37. The subsequent reduction motor 11 can be conveniently meshed with the connecting tooth plate 36 through the fixed gear 12, which can provide sufficient power for the closure of the air-tight door shell 38 and improve the closure efficiency.

[0037] The limiting sliding block 32 is matched with the guide sliding shaft 14, the supporting guide shaft 110 is matched with the guide sliding groove 35, and the sealing assembly 3 is slidably connected to the lower end surface of the guide buffer assembly 1 through the matching of the limiting sliding block 32 with the guide sliding shaft 14 and the matching of the supporting guide shaft 110 with the guide sliding groove 35, so that the stability of the displacement of the airtight door shell 38 at the bottom of the connecting rail 16 is improved, and the precision of subsequent closing is improved.

[0038] The lengths of the first buffer spring 17, the second buffer spring 18 and the third buffer spring 19 increase in order from top to bottom, and the first buffer spring 17, the second buffer spring 18 and the third buffer spring 19 are coaxial with the guide sliding shaft 14, so that the airtight door shell 38 can be gradually energy-absorbing buffered in a stepped manner, and the safety of the closing of the airtight door shell 38 is improved.

[0039] The rear end surface of the limiting spring 33 is fixedly connected with the inner wall of the connecting rail 16, when the airtight door shell 38 is located at the middle part of the connecting rail 16, the limiting spring 33 is in a relatively static state, the airtight door shell 38 is forward, and the limiting spring 33 is elastically compressed, and vice versa.

[0040] The side wall of the airtight door shell 38 is sealingly connected with the inside of the sealing clamping plate 15, the inner end surface of the airtight door shell 38 is hollow, the hollow airtight door shell 38 can effectively improve the temperature insulation and sound insulation performance of the equipment, and the sealing clamping plate 15 can provide sufficient limiting space for the side wall of the airtight door shell 38, and the sealing property of the airtight door shell 38 after closing is improved.

[0041] Working principle: before use, the user can assemble the closure fittings of the airtight door shell 38 on the sealing card 15 and the side wall of the airtight door shell 38, respectively, to facilitate subsequent closing and limiting. When the airtight door shell 38 is closed, the user can start the reduction motor 11 through the external control device. At this time, the reduction motor 11 can drive the fixed gear 12 at the bottom to rotate. At the same time, when the fixed gear 12 rotates, the fixed gear 12 can drive the airtight door shell 38 as a whole to displace on the external slide rail through the meshing with the connecting tooth plate 36. At this time, the positioning slide plate 34 at the front of the airtight door shell 38 can slide and limit in the internal connecting guide rail 16, so as to guide the airtight door shell 38. When the airtight door shell 38 is about to displace to the sealing card 15, at this time, the first buffer spring 17 in the internal connecting guide rail 16 can first elastically absorb and buffer with the limiting sliding block 32 at the side of the positioning slide plate 34. With the displacement of the positioning slide plate 34, the second buffer spring 18 and the third buffer spring 19 can elastically buffer with the limiting sliding block 32 in turn. At this time, the reduction motor 11 interrupts the power transmission. Under the action of inertia, the airtight door shell 38 gradually reduces the closing speed through the multiple buffering of the first buffer spring 17, the second buffer spring 18, the third buffer spring 19 and the limiting spring 33, so that the airtight door shell 38 can be inserted into the sealing card 15 at a slower speed, facilitating the abutment and limiting of the closure fittings in the airtight door shell 38 and the sealing card 15. When opening, the user can contact the closure fittings through the external equipment. At this time, the first buffer spring 17, the second buffer spring 18, the third buffer spring 19 and the limiting spring 33 can assist the airtight door shell 38 to open through multiple elastic forces, so that the airtight door shell 38 can quickly and conveniently slide and open at the bottom of the connecting guide rail 16. At the same time, when the airtight door shell 38 slides to a certain distance, the limiting spring 33 can elastically pull the airtight door shell 38 to prevent the airtight door shell 38 from colliding with the internal connecting guide rail 16, thereby improving the protection of the airtight door shell 38. At the same time, the air pressure sensor 312 in the airtight door shell 38 can cooperate with the air pressure control module 311 to detect and regulate the air pressure in the room, thereby improving the overall adaptability of the equipment.

[0042] Although embodiments of the present application have been shown and described, it is to be understood that various modifications, substitutions, replacements and changes can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
