Description

Technical Field

[0001] The utility model relates to the technical field of steel door leaves, and in particular to an upper and lower blocking process structure of a steel door leaf. Background Art

[0002] The appearance of steel doors on the market is very similar to anti-theft doors. In terms of anti-theft performance, standard anti-theft doors have thick steel plates and strong impact resistance, and they implement the national mandatory standards; while steel doors implement the company's own standards. Steel doors are widely used indoors and outdoors in various buildings. Steel doors used outdoors are normally used for multiple purposes. They need to be made of galvanized steel plates, and each reinforcement is welded and strengthened with oxygen shielded welding, and waterproof thresholds (or bottom seals), anti-theft pins, and high-quality UV-resistant coatings are installed to adapt to the harsh working environment of outdoor sun and rain. The existing technology has the following problems:

[0003] When most of the existing steel door leaves are closed with the door frame, the top and bottom of the door leaf may not be well sealed with the door frame due to the uneven processing of the door frame. When the door leaf is closed forcefully, the door leaf and the door frame may vibrate violently. When the user opens the door without paying attention and slams the door or a naughty child kicks the door, the door leaf will directly hit the wall, causing the door frame to vibrate and the connection with the wall to loosen, and the door leaf may be damaged due to the strong impact on the wall.

[0010] 1. The utility model provides a technical structure for sealing the upper and lower parts of a steel door leaf, and adopts the cooperation of the door leaf body, the push plate, the door frame body, the sealing groove, the rotating block and the spring in the scheme. If the door leaf body is pushed hard to close, the push plate first contacts the sealing groove provided on the inner wall of the door frame body to provide a certain shock absorption when closing the door leaf body, so as to prevent the door frame body from vibrating due to excessive force when closing the door leaf body, and damage the connection between the door frame body and the wall. After the door leaf body is completely closed, the spring reset slider pushes the rotating block, and the rotating block pushes the push plate to tightly adhere to the inner wall of the sealing groove, so that the door leaf body and the door frame body are completely sealed at the top and bottom, and the problem that the top and bottom of the door leaf may not be well sealed with the door frame due to the uneven processing of the door frame is solved.

[0020] When closing the door leaf 2, the sealing plates 4 at the top and bottom of the door leaf 2 are close to the top and bottom of the inner wall of the door frame 1, and provide a certain degree of shock absorption to the door leaf 2 and the door frame 1 when the door is closed vigorously. When opening the door, if the force of pushing the door is too great, the door leaf shock-absorbing blocks 3 on the upper and lower sides of the front side of the door frame 1 will shock the door leaf 2, and the limited door leaf 2 can only rotate to a right angle on the inner wall of the door frame 1.

[0021] like Figure 2-4 As shown, the utility model provides a steel door leaf upper and lower blocking process structure, the door leaf 2 includes a door leaf body 21, the front and rear sides of the door leaf body 21 are respectively fixedly connected with handles 22, the front middle part of the door leaf body 21 is provided with a cat's eye 23, the sealing plate 4 includes a sealing plate slide plate 41, the rear side of the sealing plate slide plate 41 is provided with a slide groove 42, the left and right sides of the inner wall of the slide groove 42 are respectively slidably connected with sliders 43, the opposite surfaces of the two sliders 43 are fixedly connected with springs 44, the ends of the two springs 44 away from the sliders 43 are respectively fixedly connected to the left and right sides of the inner wall of the sealing plate slide plate 41, the rear sides of the two sliders 43 are rotatably connected with rotating rods 45, the two rotating rods 45 are rotatably connected with a rotating block 46 on the side away from the slider 43, and the rear side of the rotating block 46 is fixedly connected with a push plate 47, and the door frame 1 includes a door frame body 11, and the top and bottom of the inner wall of the door frame body 11 are respectively provided with sealing grooves 12;

[0022] When the door leaf main body 21 is closed, if the door leaf main body 21 is pushed hard to close, the push plates 47 at the top and bottom of the door leaf main body 21 first release the sealing groove 12 opened on the inner wall of the door frame main body 11, and the push plates 47 press the rotating block 46 to rotate the rotating rods 45 on both sides. The rotating rods 45 rotate and push the sliding block 43 to slide on the inner wall of the sliding groove 42 opened on the sealing plate slide plate 41, and squeeze the spring 44. The spring 44 has a reset effect, so that when closing the door leaf main body 21, there is a certain shock absorption to prevent the door frame main body 11 from vibrating due to excessive force when closing the door leaf main body 21, and the connection between the door frame main body 11 and the wall is damaged. After the door leaf main body 21 is completely closed, the spring 44 resets the sliding block 43 to push the rotating block 46, and the rotating block 46 pushes the push plate 47 to tightly stick to the inner wall of the sealing groove 12, so that the door leaf main body 21 and the top and bottom of the door frame main body 11 are completely sealed.

[0023] like Figure 5As shown, the utility model provides a steel door leaf upper and lower blocking process structure, the door leaf shock-absorbing block 3 includes a shock-absorbing block bottom plate 31, a shock-absorbing block slide groove 32 is opened on the left side of the shock-absorbing block bottom plate 31, and the inner wall of the shock-absorbing block slide groove 32 is slidably connected with shock-absorbing block sliders 33 on the upper and lower sides respectively, and the left sides of the two shock-absorbing block sliders 33 are slidably connected with shock-absorbing block rotating rods 34, and the two shock-absorbing block rotating rods 34 are rotatably connected with the middle rotating shaft 39 on the side away from the shock-absorbing block slider 33, and the opposite sides of the two middle rotating shafts 39 are fixedly connected with second springs 35, and the inner walls of the two middle rotating shafts 39 are rotatably connected with second rotating rods 36 on the side away from the shock-absorbing block rotating rods 34, and the two second rotating rods 36 are rotatably connected with the second sliders 37 on the side away from the middle rotating shaft 39, and the left sides of the two second sliders 37 are movably connected with shock-absorbing blocks 38, and the outer walls of the two second sliders 37 are slidably connected to the inner walls of the shock-absorbing blocks 38;

[0024] When the door leaf main body 21 is opened, the door leaf main body 21 rotates on the inner wall of the door frame main body 11. When the door leaf main body 21 rotates past a right angle and continues to rotate, the front side of the door leaf main body 21 squeezes the shock-absorbing blocks 38 on the upper and lower sides. The shock-absorbing blocks 38 are squeezed and the second slider 37 slides on the inner wall of the shock-absorbing blocks 38 and the second rotating rod 36 rotates to push the middle rotating shaft 39. The middle rotating shaft 39 squeezes the second spring 35 and drives the shock-absorbing block rotating rod 34 to rotate and push the shock-absorbing block slider 33 to slide on the inner wall of the shock-absorbing block slide groove 32 opened on the shock-absorbing block bottom plate 31. The second spring 35 has a reset effect, so that when the door leaf main body 21 is opened with a large force, it performs a certain shock absorption and does not rotate directly until it hits the wall and causes damage to the door leaf main body 21.

[0025] The following is a detailed description of the working principle of the upper and lower blocking process structure of the steel door leaf.

[0026] like Figure 1-5As shown, when the door leaf body 21 is closed, if the door leaf body 21 is pushed hard to close, the push plates 47 at the top and bottom of the door leaf body 21 first release the sealing groove 12 opened on the inner wall of the door frame body 11, and the push plates 47 press the rotating block 46 to rotate the rotating rods 45 on both sides. The rotating rods 45 rotate and push the sliding block 43 to slide on the inner wall of the sliding groove 42 opened on the sealing plate slide plate 41, and squeeze the spring 44. The spring 44 has a reset effect, so that when the door leaf body 21 is closed, it has a certain shock absorption effect to prevent the door frame body 11 from vibrating due to excessive force when closing the door leaf body 21, and the connection between the door frame body 11 and the wall is damaged. After the door leaf body 21 is completely closed, the spring 44 resets the sliding block 43 to push the rotating block 46, and the rotating block 46 pushes the push plate 47 to tightly adhere to the inner wall of the sealing groove 12, so that the door leaf body 21 is completely sealed with the top and bottom of the door frame body 11. When the door leaf body 21 is opened, the door leaf body 21 rotates on the inner wall of the door frame body 11. When the door leaf body 21 rotates past a right angle and continues to rotate, the front side of the door leaf body 21 squeezes the shock-absorbing blocks 38 on the upper and lower sides. The shock-absorbing blocks 38 are squeezed and the second slider 37 slides on the inner wall of the shock-absorbing blocks 38 and the second rotating rod 36 rotates to push the middle rotating shaft 39. The middle rotating shaft 39 squeezes the second spring 35 and drives the shock-absorbing block rotating rod 34 to rotate and push the shock-absorbing block slider 33 to slide on the inner wall of the shock-absorbing block slide groove 32 opened on the shock-absorbing block bottom plate 31. The second spring 35 has a reset effect, so that when the door leaf body 21 is opened with a large force, it performs a certain amount of shock absorption and does not rotate directly until it hits the wall and causes damage to the door leaf body 21.

[0027] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
