Description

Technical Field

[0001] The utility model relates to the technical field of civil air defense engineering, and in particular to a protective door for civil air defense engineering. Background Art

[0002] Civil air defense doors, as an important part of the people's safety protection project, undertake the key task of providing safe isolation and protection in emergency situations. However, there is a common problem in actual use: due to children's curiosity and playful nature, they may turn the wheel of the civil air defense door at will, causing themselves or others to be accidentally locked in the door. Since the design and manufacture of civil air defense doors focus on protection performance and stability, the door body is usually very thick. Once a child is locked in the door, the rescue process not only requires a lot of manpower and material resources, but may also have a certain impact on the child's psychology.

[0003] In order to solve this problem, Chinese patent CN219119097U discloses a design scheme for a sealed protective door for civil air defense projects. This scheme uses a combination of rotating parts and springs to enable the insertion rod to be disengaged from the outer frame under specific conditions, thereby achieving idling of the rotating parts, which can theoretically prevent children from accidentally rotating the door body. However, this design has certain defects in practical applications. Since the insertion rod needs to be inserted into the outer frame and a force is applied to the outer frame to generate a tangential force, the insertion rod is prone to deformation when it is subjected to the large force required for the rotation of the civil air defense door. Long-term deformation and stress concentration will significantly reduce the service life of the insertion rod, thereby affecting the stability and safety of the entire civil air defense door.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. The utility model is further described in combination with the drawings and embodiments:

[0023] like Figure 1-Figure 4As shown, a civil air defense project protection door includes a door body 100, on which two sets of locking mechanisms 2 are provided, and the two sets of locking mechanisms are connected together through a central connecting plate 33. Pushing mechanisms 4 are provided on both sides of the central connecting plate, and the pushing mechanisms can drive the central connecting plate to move left and right. Through the design of the two sets of locking mechanisms and the central connecting plate, efficient locking and unlocking of the protection door is achieved, and the safety and convenience of the door are improved.

[0024] In at least one embodiment, the locking mechanism includes an upper sliding sleeve 21 and a lower sliding sleeve 24, an upper plug rod 22 is slidably fitted in the upper sliding sleeve, a lower plug rod 25 is slidably fitted in the lower sliding sleeve, an upper connecting rod 23 is rotatably connected to the lower end of the upper plug rod, and a lower connecting rod 26 is rotatably connected to the upper end of the lower plug rod, and both the upper connecting rod and the lower connecting rod are rotatably connected to a fixed plate 29, and a middle connecting plate is installed between the two fixed plates, and the middle connecting plate moves to the left so that the upper plug rod moves vertically upward along the upper sliding sleeve, while the lower plug rod moves vertically downward along the lower sliding sleeve. This locking mechanism is cleverly designed, and the synchronous reverse movement of the upper and lower plug rods is achieved through the cooperation of the connecting rod and the middle connecting plate, further enhancing the locking effect of the door.

[0025] Furthermore, the fixing plate is provided with an upper hinge seat 27 and a lower hinge seat 28, the upper hinge seat is rotatably connected to an upper connecting rod, and the lower hinge seat is rotatably connected to a lower connecting rod. The design of the hinge seat enables the connecting rod to rotate flexibly, ensuring the smoothness of the locking mechanism.

[0026] Furthermore, the door body is provided with a first guide sleeve 31 and a second guide sleeve 32, wherein a central connecting plate is slidably matched in the first guide sleeve and the second guide sleeve. The setting of the guide sleeve ensures the accuracy and stability of the movement of the central connecting plate and prevents the occurrence of deviation and jamming.

[0027] In at least one embodiment, a rotating member 5 is provided on the central connecting plate, and the rotating member cooperates with the pushing mechanism.

[0028] Specifically, the rotating member includes a central rotating shaft 51, on which a push plate 52 is rotatably connected, and the push plate is provided with a first fastening bolt 53 and a second fastening bolt 54, and in cooperation with the push plate, an upper vertical threaded hole 55, a lower vertical threaded hole 56, a left horizontal threaded hole 57 and a right horizontal threaded hole 58 are provided. When the first fastening bolt and the second fastening bolt cooperate with the left horizontal threaded hole 57 and the right horizontal threaded hole 58, the push plate is parallel to the middle connecting plate; when the first fastening bolt and the second fastening bolt cooperate with the upper vertical threaded hole 55 and the lower vertical threaded hole 56, the push plate is perpendicular to the middle connecting plate. By cooperating between the fastening bolts and different threaded holes, the angle between the push plate and the middle connecting plate is adjusted.

[0029] Furthermore, the pushing mechanism includes a turntable 48, a mounting slot 47 is provided on the door body, a turntable is rotatably connected in the mounting slot, a support seat 41 is provided on the turntable, a rotating shaft 42 is provided on the support seat, and a thrust plate 43 is rotatably connected to the rotating shaft. The design of the turntable and the thrust plate enables the operator to easily push the center connecting plate left and right, achieving a labor-saving and efficient operating experience.

[0030] Further, such as Figure 2 As shown, when the first fastening bolt and the second fastening bolt are matched with the upper vertical threaded hole 55 and the lower vertical threaded hole 56, the push plate is perpendicular to the middle connecting plate, and the thrust plate is directly below the push plate. This configuration ensures that the thrust plate can effectively push the push plate, thereby driving the middle connecting plate and the locking mechanism to operate.

[0031] In at least one embodiment, a clamping seat 44 is provided on the door body, a slot 45 for accommodating the insertion of the thrust plate is formed in the middle of the clamping seat, and rubber protrusions 46 are provided on both sides of the slot, and the rubber protrusions can squeeze the thrust plate to limit the thrust plate from rotating around the rotating shaft. The design of the clamping seat and the rubber protrusions increases the stability of the thrust plate, prevents accidental rotation, and improves the safety of operation.

[0032] Working mode, ensure that the civil air defense project protection door is in a closed state. Check whether the locking mechanism and the pushing mechanism are intact and whether the components are flexible and movable. Adjust the push plate of the rotating member to a state perpendicular to the middle connecting plate. This is usually achieved by adjusting the first fastening bolt and the second fastening bolt on the push plate so that it cooperates with the upper vertical threaded hole and the lower vertical threaded hole on the middle connecting plate. Find the pushing mechanism on the door body, specifically the turntable and the thrust plate. Rotate the thrust plate to just below the push plate and push the thrust plate away from the door body. Due to the interaction between the thrust plate and the push plate, the push plate will move horizontally to the left, thereby driving the middle connecting plate to move to the left. The movement of the middle connecting plate will cause the upper plug rod in the locking mechanism to move vertically upward along the upper sliding sleeve, while the lower plug rod will move vertically downward along the lower sliding sleeve to complete the locking of the civil air defense project protection door.

[0033] If unlocking is required, first rotate the thrust plate 180° around the shaft so that it is located on the left side of the push plate. Push the thrust plate again in the direction away from the door body, and this time the push plate will move horizontally to the right under the action of the thrust plate. As the push plate moves to the right, the middle connecting plate will also move to the right, causing the upper plug rod to move vertically downward along the upper sliding sleeve, and the lower plug rod to move vertically upward along the lower sliding sleeve, thereby completing the unlocking of the civil air defense engineering protection door.

[0034] After locking or unlocking, be sure to check whether the locking mechanism is in place correctly to ensure the door is in a safe state. Regularly check and maintain the locking mechanism and push mechanism to keep them in good working condition.

[0035] The above shows and describes the basic principles, main features and advantages of the utility model.
