For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0047] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0048] Reference Figure 1 to Figure 8, which is the first embodiment of the utility model, proposes a threshold-free, translationally-sliding, protective, and sealed civil defense door, with a trench on the ground, including: a frame 100, with a plurality of lock holes 110, for being set on a wall; a fan body 200, for being slidably set on the wall along a horizontal direction, and for sealing the frame body 100 after sliding; a plurality of lock pins 300, all of which are slidably set on the fan body 200 along a vertical direction. After the fan body 200 slides, the lock pins 300 are driven to correspond to the lock holes 110 one by one. After the lock pins 300 slide along the vertical direction, they are stuck in the lock holes 110.

[0049] In this embodiment, in order to solve the time-consuming and laborious problems of the installation of civil air defense doors in the related art, such as the need to find structural accessories in the warehouse or other locations and assemble thresholds, the frame 100 is connected to the wall through the door frame anchor hook, and multiple lock holes 110 are preset on the frame 100, without the need for the cumbersome fixing of the threshold, reducing the trouble of finding accessories and assembling on site. The fan body 200 is designed as a horizontal sliding mode, directly sliding along the wall, without the need for a threshold, to achieve a seamless seal with the frame 100, and the sealing effect is good after sliding, while also reducing the space occupied by the threshold. A number of lock pins 300 are set on the fan body 200, and these lock pins 300 slide in the vertical direction. When the fan body 200 slides, it drives the lock pin 300 to slide horizontally in the horizontal direction first, and the lock pin 300 corresponds to the lock hole 110 of the frame 100. After the lock pin 300 slides in the vertical direction, it slides into the lock hole 110 to complete the locking, ensuring the stable closure of the door, anti-theft and safety. This embodiment adopts a threshold-free design, direct wall-embedded installation of the frame 100, and a flat sliding seal of the fan body 200, which not only solves the cumbersome installation of traditional thresholds and eliminates the need to find additional accessories to assemble the threshold, saving time and effort and reducing the difficulty of installation, but also improves the overall safety and space utilization of the protective door, simplifies operation, and meets the convenience needs of modern life and public and residential areas.

[0050] Furthermore, the locking pin 300 has a first guiding inclined surface 310 . After the first guiding inclined surface 310 abuts against the locking hole 110 , the fan body 200 is driven to approach the frame body 100 , and after approaching, the frame body 100 is sealed.

[0051] In this embodiment, each lock pin 300 is provided with a first guide inclined surface 310. When the lock pin 300 contacts the lock hole 110, the first guide inclined surface 310 abuts against the inner wall surface of the lock hole 110. Through the natural angle of the inclined surface, the oblique force is used to guide the lock pin 300 during the sliding process, driving the fan body 200 to advance toward the frame body 100, that is, to slide longitudinally along the crystal direction and approach the frame body 100. With the push of the lock pin 300, the fan body 200 gradually approaches the frame body 100. This dynamic advancement process ensures that the gap between the frame body 100 and the fan body 200 is minimized, thereby achieving a close fit, improving the sealing effect, enhancing the sound insulation, dustproof and heat preservation, and meeting the efficient sealing requirements of modern door bodies. A sealing strip and a door leaf embedding strip are designed between the fan body 200 and the frame 100. The fan body 200 is close to the frame 100 to squeeze the sealing strip and the door leaf embedding strip. That is, when the door leaf is locked, the door leaf moves 20mm toward the door frame, so that the door leaf embedding strip is pressed 10mm into the door frame strip, thereby achieving a sealing effect. The introduction of the first guide slope 310 simplifies the operation process. When closing the door, the user only needs to push it lightly, and the slope of the lock pin 300 will automatically guide the fan body 200 to approach the frame 100. No additional force is required to complete the sealing, which reduces the complexity of the operation and improves the convenience of use.

[0052] Furthermore, the lock pin 300 has a guide groove 320, and the frame 100 has a protrusion 120. After the fan body 200 slides in the horizontal direction, the protrusion 120 is driven to be inserted into the guide groove 320. After being inserted, it is used to prevent the lock pin 300 from rotating.

[0053] In this embodiment, each lock pin 300 is designed with a guide groove 320, and a protrusion 120 is added to the frame 100. When the fan body 200 slides horizontally, the protrusion 120 meets the lock pin 300 and the fan body 200 is closed. The protrusion 120 is accurately inserted into the guide groove 320. After being inserted, the lock pin 300 is tightly combined with the protrusion 120 of the frame 100 to form a stable engagement. This structure prevents any unexpected rotation of the lock pin 300, and prevents the first guide inclined surface 310 and the wall of the lock hole 110 from not fitting after the lock pin 300 rotates, and the fan body 200 cannot be sealed. In this embodiment, the protrusion 120 blocks the unexpected rotation of the lock pin 300, further improving the overall stability and safety.

[0054] Furthermore, it also includes: a fixing member 400, which is arranged on the wall; a track 500, which is arranged on the fixing member 400; and a plurality of pulley blocks 600, which are arranged on the fan body 200, and the pulley blocks 600 are movably arranged on the track 500.

[0055] In this embodiment, the fixing member 400 is installed on the wall, and the track 500 is installed on the fixing member 400. The track 500 ensures the linearity of the horizontal sliding of the fan body 200. A plurality of pulley groups 600 are arranged on the fan body 200. The cooperation between the pulley groups 600 and the track 500 reduces friction, improves the smoothness of sliding, reduces noise, and increases service life.

[0056] Furthermore, both upper and lower ends of the frame 100 have locking holes 110, and the locking pin 300 includes: a screw rod 330, which has two screw rods 330, which are respectively slidably set on the fan body 200 along the vertical direction. After the two screw rods 330 slide, they are respectively inserted into the locking holes 110 at the upper and lower ends of the fan body 200, and the first guide slope 310 is located on the screw rod 330; a nut 340, which has two screw rods 330, which are respectively threadedly set. After the nut 340 rotates, it drives the screw rod 330 to slide; a driving member 350, which is set on the fan body 200, and the driving member 350 is used to drive the screw rod 330 to rotate.

[0057] In this embodiment, two screw rods 330 slide on the fan body 200 in the vertical direction. After the screw rods 330 slide, they are accurately inserted into the lock holes 110 at the upper and lower ends of the frame 100, ensuring the tight closure of the fan body 200 and the frame 100. The first guide slope 310 is located on the screw rod 330, so that the fan body 200 is close to the frame 100 after closing, so as to achieve sealing. Two screw nuts 340 are respectively threaded with the screw rod 330, and the screw nuts 340 are fixed on the driving member 350. After the screw nuts 340 rotate, the screw rod 330 is driven to slide in the vertical direction, and the sliding directions of the two screw rods 330 are opposite, which improves the closing efficiency of the door. The driving member 350 is set on the fan body 200 and directly interacts with the screw rod 330. The addition of the driving member 350 allows the screw rod 330 to rotate. The user only needs to operate the driving member 350 to complete the rotation of the screw rod 330, which improves the convenience of operation.

[0058] Furthermore, the driving member 350 includes: a rotating shaft 351, which is rotatably set on the fan body 200; a first bevel gear 352, which is set on the rotating shaft 351; the locking pin 300 also includes: a second bevel gear 360, which has two and is respectively set on the nut 340, and the second bevel gear 360 is meshed with the first bevel gear 352. After the first bevel gear 352 rotates, the two screw rods 330 are driven away from each other through the nut 340.

[0059] In this embodiment, the rotating shaft 351 provides force transmission, ensuring the stability and power source of the subsequent rotation operation. The first bevel gear 352 is set on the rotating shaft 351, and the rotation transmission is realized through the meshing of the first bevel gear 352 and the second bevel gear 360. A second bevel gear 360 is set on a nut 340. The two second bevel gears 360 are meshed with the first bevel gear 352. When the first bevel gear 352 rotates, the nut 340 is driven to rotate through the second bevel gear 360. After the nut 340 rotates, the two screw rods 330 are moved away from each other.

[0060] Furthermore, it also includes: a control member 700 rotatably disposed on the fan body 200 , and the control member 700 is used to control the rotation of the rotating shaft 351 .

[0061] In this embodiment, the control member 700 is directly mounted on the fan body 200, and the user can directly control the rotation of the shaft 351 through the control member 700, thereby simplifying the operation process. The rotation of the control member 700 can directly drive the shaft 351, thereby improving the convenience of operation, reducing the difficulty of operation, and enhancing the user's operating experience.

[0062] Furthermore, it also includes: a baffle 800, which is rotatably arranged on the ditch. After the baffle 800 rotates, it is used to open or close the ditch. It also includes: a first gear 900, which is rotatably arranged on the baffle 800; a second gear 1000, which is rotatably arranged on the ditch; a connecting rod 1100, one end of which is rotatably arranged on the first gear 900, and the other end of which is rotatably arranged on the second gear 1000. The fan body 200 has a guide bevel 210, and the baffle 800 has a second guide bevel 810 and a second guide bevel 820. After the fan body 200 slides, the guide bevel 210 is driven to abut against the second guide bevel 810 and the second guide bevel 820, and after abutting, the baffle 800 is driven to rotate.

[0063] In this embodiment, the rotation design of the baffle 800 realizes the opening and closing control of the trench. The trench can be opened or closed by simply rotating the baffle 800, which improves the convenience and practicality of the trench control. When the fan body 200 is opened, the baffle 800 closes the trench, keeps the ground flat, and improves the user experience. The first gear 900 is arranged on the baffle 800, and the second gear 1000 is arranged on the trench. The opening and closing of the trench is realized by the meshing of the first gear 900 and the second gear 1000. One end of the connecting rod 1100 rotates on the first gear 900, and the other end rotates on the second gear 1000. This connecting rod 1100 prevents the first gear 900 and the second gear 1000 from disengaging. The fan body 200 has a guide bevel 210, and the baffle 800 is designed with a second guide bevel 810 and a second guide bevel 820. After the fan body 200 slides, the guide bevel 210 abuts against the bevels of the second guide bevel 810 and the second guide bevel 820. After the abutment, the baffle 800 is driven to rotate and the trench is opened. An elastic member can be designed between the baffle 800 and the trench. When the fan body 200 is opened, the baffle 800 is directly closed automatically. Due to the elastic force of the elastic member, the baffle 800 will not be accidentally opened. Through this embodiment, not only the opening and closing control of the trench is optimized, but also the linkage between the fan body 200 and the baffle 800 is enhanced, the convenience of operation and the control accuracy are improved, the innovation and practicality of the design are reflected, and the high requirements of users for operation are met.
