The change or adjustment of their relative relationship shall also be regarded as the scope of the present invention without substantially changing the technical content.

[0055] like Figures 1 to 14 As shown, the present invention provides an urban traffic tunnel 1 that takes into account the civil air defense system, filling the gap in the field of domestic underground traffic tunnels 1 that take into account the civil air defense system. On the basis of existing tunnels, it is proposed to meet both tactical and technical requirements and the needs of civil air defense project construction, and to meet defense requirements and design standards (such as Qingdao's requirements and standards), protective equipment atlases, quality inspection standards and protective project completion acceptance standards, so that the construction of underground traffic tunnel 1 facilities takes into account the needs of civil air defense and effectively improves the city's comprehensive protection capabilities.

[0056] The system of the present invention mainly has the following innovative features: 1. Regarding the travel of personnel and materials: maximize the improvement or utilization of the tunnel entrance 11, pedestrian tunnel 12 and vehicle tunnel 13 of the existing tunnel, and reasonably determine the position and form of the entrance and exit to realize the entry and exit of personnel and materials before the war; 2. Regarding the ventilation problem in the tunnel: without affecting the normal ventilation of the tunnel, the ways and measures to ensure the internal environment are taken. Therefore, an enlarged closed passage is set at the tunnel entrance, and a developed clean exhaust protection closed door 16 and an inlet and outlet air confidential closed door 17 are set at the same time. When opened, the ventilation is not affected, and when closed before the war, it can be switched to a clean ventilation and isolation protection mode; 3. Regarding the daily life needs inside the tunnel during pre-war protection: water pipes, cables and communication pipelines are reserved in advance at the tunnel entrance 11, pedestrian tunnel 12 and vehicle tunnel 13. At the same time, the water pipes, cables, exhaust pipes and communication pipelines at the entrance are reserved in advance. Corresponding protective and sealing measures are taken for the water trench to meet the living and protection needs of the protective space in the tunnel before the war; 4. The supporting facilities of wind, water, electricity, external command and communication inside the station project: by setting up chemical defense communication contact points in appropriate areas inside the tunnel to solve the problems of internal equipment coordination, personnel and material control, and external communication information reception and feedback; 5. In view of the influence of the slope of the entrance and exit road surface that is inconvenient to close and open the door: by developing entrance and exit civil air defense doors that can adapt to large two-way slopes to facilitate normal opening / closing of the door; 6. Regarding the problem of flood prevention inside the tunnel for pre-war protection: by developing civil air defense doors that integrate flood prevention, protection and ventilation functions, and combining them with actual operating conditions, the effect of flood prevention can be achieved; 7. In view of the high humidity and salinity in the coastal city environment: the surface of the developed civil air defense doors uses high-performance anti-corrosion coatings to increase the service life of the equipment and reduce maintenance costs.

[0057] Based on the above brief introduction to the content and R&D innovation of the present invention, the following further introduces in detail the content of the urban traffic tunnel 1 of the present invention which takes into account the civil air defense system.

[0058] An urban traffic tunnel 1 taking into account the civil air defense system, such as Figures 1 to 4 As shown, it includes a traffic tunnel 1, which is an existing conventional two-way tunnel. Corresponding pedestrian tunnels 12 and vehicle tunnels 13 are set between the two-way tunnels as needed to facilitate the passage of pedestrians and material vehicles.

[0059] The tunnel entrance 11 of the traffic tunnel 1 is retracted inward by 9 meters to 12 meters (preferably 10 meters) to form a retracted section. The retracted section of the traffic tunnel 1 is provided with a steel structure double-leaf civil defense door without a threshold. By retracting the tunnel entrance 11 inward, an installation space can be provided for the steel structure double-leaf civil defense door without a threshold, and the normal passage of the traffic tunnel 1 is ensured when it is opened, and a protective space is formed inside the traffic tunnel 1 when it is closed. Among them, the steel structure threshold-free double-leaf civil defense door includes a clean exhaust protection closed door 16 and an air inlet and exhaust confidential closed door 17. The clean exhaust protection closed door 16 is located on the side close to the outside of the traffic tunnel 1, wherein the clean exhaust protection closed door 16 can switch the mode of clean ventilation or isolation protection, and the air inlet and exhaust confidential closed door 17 can realize ventilation and wind guiding functions in the traffic tunnel 1 through a fan (the air inlet and exhaust confidential closed door 17 itself has an air inlet fan / exhaust fan); therefore, when the steel structure threshold-free double-leaf civil defense door is closed before the war, the air inlet and exhaust confidential closed door 17 realizes directional ventilation in the traffic tunnel 1 through a fan, and the clean exhaust protection closed door 16 can be switched to a clean ventilation form or an isolation protection mode.

[0060] At the same time, a temporary personnel sheltering area 14 and a temporary material sheltering area 15 are arranged on the wall of one lane of the traffic tunnel 1. There are multiple temporary personnel sheltering areas 14 and temporary material sheltering areas, which are adjacently staggered and used for the placement of temporary personnel and the storage of temporary materials before or during war. The pedestrian tunnel 12 and the vehicle tunnel 13 of the traffic tunnel 1 are both provided with a two-way force-protected closed door 18 to ensure the normal passage of pedestrians or vehicles when opened, and to shelter temporary personnel and materials when closed, and to facilitate the temporary evacuation of people or vehicles.

[0061] In the present air defense system, in order to facilitate the normal life of the people in the tunnel before or during the war, the tunnel entrance 11, the pedestrian tunnel 12 and the vehicle tunnel 13 of the traffic tunnel 1 are all reserved in advance with water pipes, cables and communication pipelines, and these water pipes, cables and communication pipelines take corresponding protective and sealed measures when passing through the protective and sealed walls (such as setting a two-way force-bearing protective sealed door 18 in the pedestrian tunnel 12 and the vehicle tunnel 13, setting a closed gate or isolation net in the corresponding water channel or pipeline, etc.), so as to ensure that the air defense space formed inside the traffic tunnel 1 before or during the war reaches a relatively safe protection level, meet the normal life of the people in the traffic tunnel 1, and maintain normal information communication with the outside world when necessary.

[0062] In this air defense system, the clean exhaust protection closed door 16, air inlet and exhaust confidential closed door 17, and two-way force protection closed door 18 developed have the following technical indicators: 1. The resistance level of nuclear weapons is 5 to 6; 2. The resistance level of conventional weapons is 5 to 6; 3. The chemical defense level is Class D; 4. The maximum allowable air leakage Qy≤5.28m at an overpressure of 50Pa. 3 / h; 5. The time for switching between peacetime and wartime functions is ≤20 minutes when there are no less than 4 operators or no less than 2 operators for each door; 6. The road surface adopts a threshold-free or trench-free step, and the structure realizes barrier-free passage; 7. Adaptation to civil engineering conditions: longitudinal slope ≤3%, door opening in the uphill direction; 8. Flood prevention function: flood prevention head ≤15 meters; 9. Ventilation performance of clean exhaust protection closed door 16: when the ventilation resistance of door leaf 20 valve group is ≤250Pa, the ventilation volume of door leaf 20 valve group is ≥20000m 3 / h.

[0063] In the present air defense system, the existing traffic tunnel 1 is sometimes set in a coastal location, so there is a situation of high humidity and salinity. The problem of equipment corrosion needs to be considered when developing the equipment. Therefore, the surfaces of the clean exhaust protection closed door 16, the air inlet and exhaust confidential closed door 17, and the two-way force protection closed door 18 of the present invention are coated with epoxy anti-corrosion coating or POZD high-performance anti-corrosion coating to increase the service life of the equipment and reduce maintenance costs. At the same time, the air defense system formed by the sealed door of the traffic tunnel 1 before or during the war can further improve the protection and air defense effects.

[0064] In this air defense system, if Figures 4 to 7 As shown, considering the extreme disaster problem of urban waterlogging, it is also necessary to comprehensively consider the flood prevention requirements when developing equipment. Therefore, the clean exhaust protection closed door 16 developed is also designed as follows: the clean exhaust protection closed door 16 is provided with a small flood prevention door system 2, which is used for people to pass through and is convenient for draining water outward to achieve the purpose of flood prevention inside the air defense system (i.e., inside the traffic tunnel 1). The small flood prevention door system 2 includes a small door 21 and a flood prevention door 22 opened under the door leaf 20 of the clean exhaust protection closed door 16. The number of small doorways 21 can be set on one or two door leaves 20 according to actual needs. The flood prevention door 22 is hinged on the door frame 19 of the small doorway 21 and can close the small doorway 21 in an airtight manner; the flood prevention door 22 is convenient for timely drainage when flooding occurs to prevent flooding in the traffic tunnel 1.

[0065] Regarding the locking function of the anti-flood door 22, a wrench-type door lock 23 is provided on the anti-flood door 22. The wrench-type door lock 23 is provided with a wrench and a lock, and the lock is directly controlled to be closed by the wrench. At the same time, a boss is also provided on the inner wall of the small door 21, and a sealing ring is provided on the boss. At the same time, the outer peripheral surface of the anti-flood door 22 is provided with a groove adapted to the boss, and a sealing ring is also provided in the groove. Therefore, after closing the anti-flood door 22, the groove of the anti-flood door 22 can be well adapted to the boss of the small door 21 to achieve a primary waterproof seal. At the same time, the sealing ring of the anti-flood door 22 and the sealing ring of the small door 21 can squeeze each other, thereby achieving a secondary waterproof seal. It can be seen from this that after closing the anti-flood door 22, a good sealing and waterproof effect can be achieved.

[0066] In this air defense system, if Figures 4 to 9 As shown, the tunnel entrance 11, pedestrian tunnel 12 and vehicle tunnel 13 of the traffic tunnel 1 can be used for traffic or pedestrians to pass through after the closed doors are opened. Therefore, the installation floors corresponding to the clean exhaust protection closed doors 16, air inlet and exhaust protection closed doors 17, and two-way force protection closed doors 18 adopted by this system are all designed without thresholds to facilitate barrier-free passage of pedestrians or vehicles. Based on this, in order to further improve the sealing between the closed doors and the ground in the traffic tunnel 1 after they are closed, so as to achieve a waterproof effect, the clean exhaust protection closed doors 16, air inlet and exhaust protection closed doors 17, and two-way force protection closed doors 18 are designed as follows: the clean exhaust protection closed doors 16, air inlet and exhaust protection closed doors 17, and two-way force protection closed doors 18 all include door frames 19 and double-leaf door panels 20 arranged on the door frames 19, and the bottom of the door frames 19 is provided with There is a lifting bottom beam mechanism 3, which includes a rotating member 31, a crank connecting rod 32 and a bottom beam 33; the rotating member 31 can be a manual operating member (such as a manual wrench or a hand wheel 72, etc.) or an electric operating member (such as a servo motor or a reduction motor, etc.), the rotating member 31 is arranged on the door frame 19, the crank end of the crank connecting rod 32 is connected to the rotating end of the rotating member 31, the bottom beam 33 is arranged at the connecting rod end of the crank connecting rod 32, and the bottom beam 33 is located between the vertical beams on both sides of the door frame 19. Therefore, under the limiting action of the two vertical beams, when the rotating member 31 rotates, the crank connecting rod 32 drives the bottom beam 33 to be pressed down and then pressed against the ground (the ground can be the geographical ground in the traffic tunnel 1, or the steel or metal plate at the bottom end of the door frame 19) to improve the sealing between the bottom beam 33 and the ground.

[0067] Regarding the lifting and lowering bottom beam mechanism 3, in order to improve the stability of the lifting and lowering movement of the bottom beam 33, the number of rotating parts 31 can be set to multiple, and the multiple rotating parts 31 are evenly distributed on the bottom beam 33, so that when the multiple rotating parts 31 work synchronously, the multiple crank connecting rods 32 can generate downward pressure on the bottom beam 33 and evenly distribute it on the bottom beam 33, thereby improving the stability of the downward movement of the bottom beam 33 to reduce the occurrence of movement jams. In addition, the bottom surface of the bottom beam 33 is also provided with a hollow rubber strip, and the cross section of the hollow rubber strip is wedge-shaped, so that in the process of the bottom beam 33 moving downward, the hollow rubber strip can improve the sealing between the bottom beam 33 and the ground by deforming itself, and at the same time, the wedge-shaped surface of the hollow rubber strip can increase the contact area between the bottom beam 33 and the ground, so as to further improve the sealing, thereby improving the waterproof effect after the installation of the closed door.

[0068] In this air defense system, if Figures 4 to 10As shown, the ventilation and exhaust functions in the traffic tunnel 1 are mainly realized by means of the clean exhaust protection sealed door 16 and the air inlet and exhaust confidentiality sealed door 17, wherein the air inlet and exhaust confidentiality sealed door 17 mainly directionalizes the wind in the traffic tunnel 1 through the air inlet fan and / or the exhaust fan, and the clean exhaust protection sealed door 16 can be switched to the clean ventilation mode or the isolation protection mode.

[0069] The following is an introduction to the structure of the clean exhaust protection sealed door 16 for switching between clean ventilation mode or isolation protection: the door leaf 20 of the clean exhaust protection sealed door 16 is provided with a ventilation window 4 and an electric protection sealing door 5, and the electric protection sealing door 5 is used to open or close the ventilation window 4 to control the ventilation condition of the traffic tunnel 1. The electric protective sealing door 5 includes a rotating drive member 51, a rotating shaft 52, a transmission rod 53, a pull rod 54, a slider 55, a slide rail 56 and a sealing plate 57. The rotating drive member 51 adopts a motor seat and a motor arranged on the motor seat. The rotating drive member 51 is arranged on the door leaf 20. The rotating shaft 52 rotates coaxially with the driving end of the rotating drive member 51. The rotating shaft 52 is relatively parallel to the door leaf 20 and is vertically arranged. The transmission rod 53 is connected to the rotating shaft 52 (the connection can be fixed by welding or pinning, etc.), the slide rail 56 is installed on the sealing plate 57 by screw locking, the slide rail 56 is distributed horizontally, the slider 55 is slidably connected to the slide rail 56, one end of the pull rod 54 is hinged to the end of the transmission rod 53, and the other end of the pull rod 54 is hinged to the slider 55. Therefore, the rotating driving member 51 works by driving the rotating shaft 52 and the transmission rod 53 to rotate synchronously, and the pull rod 54 pulls or pushes the slider 55 to slide adaptively on the slide rail 56, while driving the sealing plate 57 to rotate to open or close the ventilation window 4.

[0070] Regarding the electric protective closed door structure, in order to improve the stability of driving the cover plate 57 to flip and improve the wind resistance of the cover plate 57, it also includes two transversely distributed reinforcement rods 58, a sliding block 59 slidably adapted on the reinforcement rod 58, and a linkage rod 60 connected to the sliding block 59 and the slider 55 at both ends, so that when the rotating driving member 51 is working, under the rotation and traction of the pull rod 54, the sliding block 59 and the linkage rod 60 will slide simultaneously with the slider 55 to improve the stability of the flipping movement of the cover plate 57. Among them, the traction mechanism formed by the transmission rod 53, the pull rod 54, the slider 55, the slide rail 56 and the reinforcement rod 58 can be designed as one or more according to the high adaptability of the cover plate 57, so that the traction force on the cover plate 57 is uniform, thereby achieving the improvement of the stability of driving the flip cover plate 57, wherein the design of the reinforcement rod 58 can better improve the wind resistance of the cover plate 57 and improve the protective effect of the clean exhaust protective closed door 16.

[0071] In the present air defense system, since the ventilation window 4 is directly exposed to the outside world, the explosion-proof wave situation in wartime also needs to be considered during the design. Therefore, the present invention also carries out the following structural design on the explosion-proof wave capability of the ventilation window 4: the ventilation window 4 is provided with an explosion-proof wave valve assembly 41, and the explosion-proof wave valve assembly 41 is used to improve the protective performance of the clean exhaust protection closed door 16; the explosion-proof wave valve assembly 41 includes a plurality of explosion-proof wave valve units integrated on the ventilation window 4, and the explosion-proof wave valve unit includes an air supply channel and a wave-breaking pipe arranged in the air supply duct, and the air supply channel and the wave-breaking pipe are both in a cone shape, and the air supply channel is close to the traffic tunnel. 1 is provided with an elastic member at the end outside, which may be a spring, and the end of the elastic member is connected to the end of the wave-breaking pipe, and the spring is in a natural state; when the air flow velocity in the air supply channel is not greater than a threshold value, under the elastic force of the elastic member, the wave-breaking pipe does not close the air supply channel, so the gap between the wave-breaking pipe and the air supply channel is used for ventilation; when the air flow velocity in the air supply channel is greater than a threshold value, the wave-breaking pipe is affected by the air flow and overcomes the elastic force of the spring, moves in the air supply channel and closes the air supply channel, thereby preventing the explosion-proof wave generated outside the traffic tunnel 1 from entering the traffic tunnel 1, thereby playing a good role in mobile explosion-proof and protection.

[0072] It can be seen that the present invention arranges an explosion-proof wave unit on the ventilation window 4. When an explosion-proof wave is generated outside the war traffic tunnel 1, the ventilation window 4 of the clean exhaust protection closed door 16 of the present invention can quickly close the air supply channel. It not only has a high wave elimination rate, but also a fast reaction speed. According to experimental measurements, the pressure peak wave elimination rate of the closed door is 91%, the energy wave elimination rate is greater than 99%, and the residual pressure behind the valve is less than 0.03MPa.

[0073] In this air defense system, if Figures 4 to 11 As shown, since the traffic tunnel 1 is usually built according to the actual terrain, the tunnel entrance 11, the pedestrian tunnel 12, and the vehicle tunnel 13 may have ups and downslopes. Therefore, when the opening direction of the closed door is uphill, it will cause the closed door to be stuck when opening, because the closed door developed by this system also needs to consider the upslope problem in the opening direction. In this regard, the present invention designs the closed door as follows: a liftable door shaft mechanism 6 is provided between the door leaf 20 and the door frame 19 of the clean exhaust protection closed door 16, the air inlet and exhaust protection closed door 17, and the two-way force protection closed door 18. The liftable door shaft mechanism 6 can synchronously lift the door leaf 20 through the lifting door shaft 62, thereby overcoming the upslope problem in the door opening direction, so that the door can be opened smoothly, and the efficiency of opening or closing the door can be improved before or during the war, and the operation is convenient.

[0074] The liftable door axis mechanism 6 includes a plurality of door frame connection seats 61, a door axis 62, and a door leaf connection seat 64. The plurality of door frame connection seats 61 are connected to the door frame 19. The door axis 62 adopts a multi-section door axis 62. The multi-section door axis 62 is connected by a sleeve 63. The door axis 62 is fixedly connected to the plurality of door frame connection seats 61 (the fixed connection method can be welding or bolt fixing). The door leaf connection seat 64 is locked and connected to the side edge of the door leaf 20 by bolts. The door leaf connection seat 64 is provided with A plurality of sliding supports 65 are sleeved on the surface of the door shaft 62, and the plurality of sliding supports 65 are staggered with the plurality of door frame connecting seats 61; when the tunnel entrance 11, the pedestrian tunnel 12, and the vehicle tunnel 13 of the traffic tunnel 1 are uphill and downhill, when the clean exhaust protection closed door 16, the air inlet and exhaust protection closed door 17, and / or the two-way force protection closed door 18 are opened, the door leaf 20 and the door shaft 62 are lifted as the slope increases to reduce the possibility of the door getting stuck when opening.

[0075] Since the door shaft 62 of the present invention is connected in multiple sections through the sleeve 63, it is also necessary to consider the situation where the sliding support 65 slides out of the door shaft 62 or collides and interferes with the sleeve 63. The liftable door shaft mechanism 6 of the present invention also includes a limiting roller 66 mechanism. There are multiple limiting rollers 66, which are respectively arranged on the door frame connecting seat 61 at the end and the door frame connecting seat 61 close to the sleeve 63. The wheel surface of the limiting roller 66 is made of rubber material, and the wheel surface of the limiting roller 66 is against the outer peripheral surface of the door shaft 62, and the wheel axle of the limiting roller 66 is perpendicular to the door shaft 62; at the same time, limiting grooves are provided on both sides of the surface of the door shaft 62 on the limiting roller 66. When opening or closing the door, when the door leaf 20 moves up and down the slope, when the limiting groove cooperates with the limiting roller 66, the continued lifting and lowering movement of the door leaf 20 can be limited to prevent the door leaf 20 from continuing to lift and lowering and causing the sliding support 65 to slide out of the door shaft 62 or collide with the sleeve 63, thereby playing a role of limiting and protection.

[0076] In this air defense system, if Figures 4 to 14 As shown, the clean exhaust protection closed door 16, the air inlet and exhaust protection closed door 17, and the two-way force protection closed door 18 are all provided with a door leaf locking mechanism 7. When closing the clean exhaust protection closed door 16, the air inlet and exhaust protection closed door 17, and the two-way force protection closed door 18 before the battle, the door leaf 20 is manually or automatically closed through the door leaf locking mechanism 7, which can improve the closing efficiency and facilitate the operation.

[0077] The door leaf locking mechanism 7 includes a first commutator 71, a hand wheel 72, a first rotating rod 73, a second commutator 74, an upper sleeve assembly 75, an upper latch member 76, a lower sleeve assembly 77, and a lower latch member 78; the first commutator 71 and the second commutator 74 both adopt worm gear commutators; the first commutator 71 and the second commutator 74 are both arranged on the door leaf 20, the hand wheel 72 is connected to the turbine end of the first commutator 71, one end of the first rotating rod 73 is connected to the worm end of the first commutator 71, and the other end of the first rotating rod 73 is connected to the turbine end of the second commutator 74, the upper sleeve assembly 75 and the lower sleeve assembly 77 are respectively connected to the two worm ends of the second commutator 74, the upper latch member 76 is connected to the end of the upper sleeve assembly 75, and the lower latch member 78 is connected to the end of the lower sleeve assembly 77. Therefore, when the hand wheel 72 is rotated, the first commutator 71 can vertically transmit the rotation direction of the hand wheel 72 to the first rotating rod 73 through the internal worm gear structure. Similarly, when the first rotating rod 73 rotates, the second commutator 74 can vertically transmit the rotation direction of the first rotating rod 73 to the upper sleeve assembly 75 and the lower sleeve assembly 77 through the internal worm gear structure. The telescopic function of the upper sleeve assembly 75 and the lower sleeve assembly 77 is utilized to adjust the upper latch member 76 and the lower latch member 78 to move upward and downward respectively, so as to engage with the door frame 19 to achieve locking. When closing the sealed door before the battle, it can be achieved by a small number of operators, which has the advantages of simple and efficient operation and saving manpower.

[0078] In order to improve the stability of the closed door when it is locked, the door leaf locking mechanism 7 of the present invention is provided with two symmetrical groups of upper latch members 76 and lower latch members 78 at the two worm ends of the first commutator 71, and there are two upper latch members 76 and lower latch members 78 in each group. In order to facilitate the use of the hand wheel 72 to simultaneously drive the four upper latch members 76 to move up and down synchronously, the door leaf locking mechanism 7 also includes a second rotating rod 79, a third commutator 80, a fourth commutator 82, a third rotating rod 81, and the third commutator 80 and the fourth commutator 8 2 are all arranged on the door leaf 20, the two ends of the second rotating rod 79 are respectively connected to the worm end of the second commutator 74 and the worm end of the third commutator 80, the other worm end of the third commutator 80 is connected to the upper latch member 76 through the upper sleeve assembly 75, the two ends of the third rotating rod 81 are respectively connected to the turbine end of the third commutator 80 and the turbine end of the fourth commutator 82, and the two worm ends of the fourth commutator 82 are respectively connected to the upper latch member 76 and the lower latch member 78 through the upper sleeve assembly 75 and the lower sleeve assembly 77. Therefore, when the hand wheel 72 is turned, the lifting and locking functions of the plurality of upper latch members 76 and the lower latch members 78 are realized at the same time through the first commutator 71, the first rotating rod 73, the second commutator 74, the second rotating rod 79, the third commutator 80, the third rotating rod 81 and the fourth commutator 82, so that when closing the door before the battle, a small number of operators can be used to realize the door closing action, which has the effect of convenient and efficient operation.

[0079] Regarding the upper sleeve assembly 75 and the lower sleeve assembly 77 of the present invention, the structures of the upper sleeve assembly 75 and the lower sleeve assembly 77 are the same. Taking the upper sleeve assembly 75 as an example, the upper sleeve assembly 75 includes a threaded sleeve 751 and a threaded rod 752 that are threadedly matched. The end of the threaded rod 752 is connected to the worm end of the commutator (which may be the second commutator 74, the third commutator 80, or the fourth commutator 82), and the threaded sleeve 751 is connected to the upper latch member 76. Under the limiting action of the upper latch member 76 and / or the lower latch member 78, when the worm end of the commutator (which may be the second commutator 74, the third commutator 80, or the fourth commutator 82) rotates, the lifting and lowering functions of the upper latch member 76 and / or the lower latch member 78 can be controlled by the thread adjustment principle.

[0080] Regarding the upper latch member 76 of the present invention, a plurality of lock holes corresponding to the upper latch member 76 are opened on the top surface of the door frame 19. Under the driving action of the hand wheel 72, the upper latch member 76 cooperates with the corresponding lock holes through lifting movement, thereby achieving the function of locking the door. Among them, the upper latch member 76 includes a door top support 761, a driving rod 762, a lever 763 and an insertion rod 764. The door top support 761 is arranged at the top of the door leaf 20. The door top support 761 has an inner cavity. The inner bottom surface of the inner cavity is provided with a socket corresponding to the lock hole. One end of the driving rod 762 is connected to the upper sleeve assembly 75, and the other end of the driving rod 762 is plugged into the bottom surface of the door top support 761 and is located in the inner cavity. The middle part of the lever 763 is rotatably connected to the inner wall of the inner cavity. The lever 763 is located between the socket and the driving rod 762. One end of the lever 763 is hinged to the end of the driving rod 762, and the other end of the lever 763 is glued to one end of the insertion rod 764, and the other end of the insertion rod 764 is opposite to the socket. Therefore, according to the principle of lever 763, when the driving rod 762 rises, the lever 763 will drive the insertion rod 764 to be inserted into the socket and adapt to the corresponding lock hole on the door frame 19, thereby achieving the function of door lock. Conversely, when the driving rod 762 descends, the lever 763 will drive the insertion rod 764 to move upward to be stored in the inner cavity, and at the same time contact the door lock locking function, so it has the effect of simple and efficient operation.
