[0025] The following is combined with Figure 1-2 This application is described in further detail.

[0026] The embodiment of the present application discloses a door frame for a civil air defense door. Figure 1 and Figure 2 The door frame of the civil air defense door includes an outer frame 1, which is arranged in a vertical direction. A grouting groove 2 is opened in the outer frame 1. A feed hole 5 is opened at the upper end of the outer frame 1. The feed hole 5 is used to communicate with a feed hopper, and the feed hole 5 is connected to the grouting groove 2.

[0027] Reference Figure 2 A vibrating rod 3 is slidably arranged in the grouting groove 2, and the length direction of the vibrating rod 3 is parallel to the length direction of the outer frame 1, and the sliding direction of the vibrating rod 3 is parallel to the length direction of the outer frame 1. A guide cylinder 8 is fixed to the bottom wall of the grouting groove 2, and the vibrating rod 3 is slidably arranged in the guide cylinder 8. The cross-sections of the vibrating rod 3 and the guide cylinder 8 are both rectangular. Through the sliding cooperation between the vibrating rod 3 and the guide cylinder 8, the sliding of the vibrating rod 3 is guided, and at the same time, the lower end of the vibrating rod 3 is not easy to abut against the cement slurry to affect its up and down sliding; a sliding component for driving the vibrating rod 3 to slide is arranged in the grouting groove 2.

[0028] When pouring cement slurry into the grouting groove 2 through the feed hopper, the vibrating rod 3 is driven to slide up and down through the sliding assembly. The vibrating rod 3 can drive the surrounding cement slurry to vibrate through friction, which helps to reduce the gaps and bubbles in the cement slurry in the grouting groove 2, improve the density of the cement slurry in the grouting groove 2, and ensure the strength of the outer frame 1 to a certain extent.

[0029] Reference Figure 2 In order to facilitate the sliding of the vibrating rod 3, the sliding assembly includes a cam 4, an abutment plate 12 and a rotating member. The cam 4 is rotatably arranged on the inner wall of the grouting groove 2, the rotation axis of the cam 4 is perpendicular to the sliding direction of the vibrating rod 3, the rotation axis of the cam 4 is perpendicular to the depth direction of the feed hole 5, and the cam 4 is located on one side of the vibrating rod 3; the abutment plate 12 is fixed on the top end of the vibrating rod 3, the abutment plate 12 is located above the cam 4 and abuts against the cam 4, the rotating member is arranged in the grouting groove 2, and the rotating member is used to drive the cam 4 to rotate.

[0030] Reference Figure 2In order to facilitate driving the cam 4 to rotate, the rotating part includes a rotating rod 6 and a fan blade 7. The rotating rod 6 is coaxially fixed on the cam 4, and the rotating rod 6 is rotatably connected to the inner wall of the grouting groove 2, so that the cam 4 rotates in the grouting groove 2 through the rotating rod 6; the rotating rod 6 is located below the feed hole 5, and a plurality of fan blades 7 are provided. The plurality of fan blades 7 are fixed at intervals along the circumference of the rotating rod 6, and the fan blades 7 are located on the side of the cam 4 away from the vibrating rod 3, and the fan blades 7 extend in the direction away from the rotating rod 6, and the fan blades 7 are used to abut against the cement slurry entering from the feed hole 5.

[0031] When cement slurry enters the grouting groove 2 from the feed hole 5, the cement slurry falls onto the fan blades 7 extending from the bottom, and the fan blades 7 begin to rotate under the action of the gravity of the cement slurry. Since there are multiple fan blades 7, the fan blades 7 can drive the rotating rod 6 to rotate continuously as the cement slurry continues to enter, and the rotating rod 6 drives the cam 4 to rotate. The outer wall of the cam 4 slides and abuts against the abutment plate 12, so that the abutment plate 12 drives the vibrating rod 3 to slide up and down under the action of its own gravity and the abutment of the cam 4, so that the vibrating rod 3 can drive the surrounding cement slurry to vibrate, which helps to reduce the gaps and bubbles in the cement slurry in the grouting groove 2, improve the density of the cement slurry in the grouting groove 2, and ensure the strength of the outer frame 1 to a certain extent.

[0032] Reference Figure 2 An elastic member 9 is fixed between the bottom wall of the guide cylinder 8 and the lower end of the vibrating rod 3. The elastic member 9 is a spring. The extension direction of the spring is parallel to the sliding direction of the vibrating rod 3. One end of the spring is fixed to the bottom wall of the guide cylinder 8, and the other end is fixed to the lower bottom wall of the vibrating rod 3. The spring is used to pull the vibrating rod 3 to slide in a direction away from the feeding hole 5. In other embodiments, the spring can be replaced by an elastic rope.

[0033] When the cam 4 pushes the abutment plate 12 to drive the vibrating rod 3 to slide upward, the vibrating rod 3 pulls the spring to stretch the spring. When the short side of the cam 4 abuts against the abutment plate 12, the vibrating rod 3 will move downward under the pull of the spring, ensuring that the abutment plate 12 is always in contact with the outer wall of the cam 4, thereby helping to ensure the reciprocating sliding of the vibrating rod 3.

[0034] Reference Figure 2 A plurality of vibrating blocks 10 are fixedly arranged on the outer walls of the two opposite sides of the vibrating rod 3. The plurality of vibrating blocks 10 on each side of the vibrating rod 3 are arranged at intervals along the length direction of the vibrating rod 3, and the vibrating blocks 10 are tilted downward away from the side of the vibrating rod 3. When the vibrating rod 3 slides, the vibrating blocks 10 are driven to move, and the vibrating blocks 10 help to compact the cement slurry and improve the density of the cement slurry.

[0035] Reference Figure 2A plurality of reinforcing plates 11 are fixed on the inner walls on the opposite sides of the grouting groove 2, the guide cylinder 8, the vibrating rod 3 and the cam 4 are all located between the reinforcing plates 11 on both sides, and the cam 4 and the rotating rod 6 are located above the plurality of reinforcing plates 11, so that the fan blades 7 are not easy to interfere with the reinforcing plates 11; the plurality of reinforcing plates 11 on each side of the grouting groove 2 are spaced apart along the length direction of the outer frame 1, and the side of the reinforcing plate 11 close to the vibrating rod 3 is tilted downward, and the plurality of reinforcing plates 11 on the opposite sides of the grouting groove 2 are staggered.

[0036] When cement slurry enters the grouting groove 2, it is easier to fall due to the action of the inclined reinforcing plate 11. At the same time, multiple reinforcing plates 11 on both sides are staggered to facilitate the passage of cement slurry, which can not only further enhance the strength of the outer frame 1, but also prevent the cement slurry from being easily blocked between the reinforcing plates 11 on the opposite sides.

[0037] The implementation principle of the embodiment of the present application is as follows: when in use, cement slurry is poured into the grouting groove 2 through the feed hopper, and the cement slurry entering the grouting groove 2 from the feed hole 5 falls onto the fan blades 7 below, driving the fan blades 7 to rotate. Since there are multiple fan blades 7, as the cement slurry continues to enter, the fan blades 7 can drive the rotating rod 6 to rotate continuously, and the rotating rod 6 drives the cam 4 to rotate. The outer wall of the cam 4 slides and abuts against the abutment plate 12, pushing the abutment plate 12 to drive the vibrating rod 3 to slide up and down, so that the vibrating rod 3 and the vibrating block 10 drive the surrounding cement slurry to vibrate, which helps to reduce the gaps and bubbles between the cement slurry in the grouting groove 2, improve the density of the cement slurry in the grouting groove 2, and ensure the strength of the outer frame 1 to a certain extent.

[0038] The remaining structures of the applicant's anti-door door frame are the same as those in the related art and will not be described in detail here.

[0039] The embodiment of the present application also discloses a civil air defense door, which includes the civil air defense door frame.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
