Description

Technical Field

[0001] This utility model relates to the field of entrance door technology, and in particular to a prefabricated steel entrance door. Background Technology

[0002] The front door is an indispensable part of a residential building. It not only separates the interior space from the outside world, ensuring privacy and security, but also plays a crucial role in the comfort, ventilation, and sound insulation of the living environment. As the first barrier of the home, the design of the front door not only affects the appearance and overall atmosphere of the house, but also directly relates to the daily experience of the residents.

[0003] A search revealed that application number CN202223089354.7 discloses a prefabricated steel entrance door, including a door frame. A lower door panel is rotatably connected to the surface of the door frame via hinges. A door lock plate is detachably connected to the surface of the lower door panel. An upper door panel frame is rotatably connected to the surface of the door frame via hinges, and the upper door panel frame and the lower door panel are detachably connected. An upper door panel swivel is detachably connected to the surface of the upper door panel frame. A first connecting shaft is detachably connected to the upper door panel swivel and the upper door panel frame. A second connecting shaft is detachably connected to the upper door panel swivel and the upper door panel frame. The first connecting shaft and the second connecting shaft are movably connected.

[0004] In the aforementioned existing technical solutions, although the upper part of the entrance door can be rotated by folding down the upper door panel to open the door for ventilation, this design has a problem: when the upper part of the door is open, it cannot effectively prevent mosquitoes from entering, which will cause mosquitoes to fly into the room and affect the comfort of living.

[0005] Therefore, we propose a prefabricated steel entrance door. Utility Model Content

[0006] The present invention aims to solve the technical problems existing in the prior art and provide a prefabricated steel entrance door.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a prefabricated steel entrance door, comprising a door frame body and a door panel body. A ventilation opening is provided on the upper surface of the door frame body, and a ventilation door panel is rotatably connected to the inner cavity of the ventilation opening via a hinge. A fixed frame is fixedly installed on the front wall of the door frame body, and a mesh plate is provided inside the fixed frame. A mosquito net is fixedly connected to the inner wall of the mesh plate. The side wall of the mesh plate away from the door frame body has symmetrically provided mounting grooves on the left and right sides. Two actuating plates are respectively provided in the two mounting grooves, and disassembly and assembly mechanisms for disassembling and assembling the mosquito net are respectively provided on the two actuating plates. The disassembly and assembly mechanisms include a telescopic rod, a telescopic spring, and two insert rods.

[0008] As a preferred embodiment of this utility model, the position of the fixing frame corresponds to the position of the ventilation opening, and the inner wall of the fixing frame is flush with the edge of the ventilation opening.

[0009] As a preferred embodiment of this utility model, the outer walls of the two actuating plates are slidably connected to the inner walls of the mounting grooves.

[0010] As a preferred embodiment of this utility model, the two ends of the telescopic rod are respectively fixedly connected to the wall surface of the two actuating plates that are close to each other, and the telescopic spring is sleeved on the outside of the telescopic rod.

[0011] As a preferred technical solution of this utility model, the two insert rods are fixedly connected to the wall surfaces of the two actuating plates at opposite ends, and the other ends of the two insert rods extend through the mesh plate to the outside of the mesh plate, and the two insert rods are slidably connected to the mesh plate.

[0012] As a preferred technical solution of this utility model, the fixing frame is adapted to the mesh plate, and the upper and lower inner walls of the fixing frame are provided with positioning holes corresponding to the insertion rod, and the positioning holes are adapted to the insertion rod.

[0013] This utility model provides a prefabricated steel entrance door. It has the following advantages:

[0014] 1. This type of prefabricated steel entrance door allows for ventilation by opening the ventilation door panel when needed. The mosquito net effectively blocks mosquitoes from entering the room. When dust accumulates on the mosquito net surface and cleaning is required, the operator simply pushes the two lever plates on the mounting slot closer together, which in turn squeezes the telescopic rod and telescopic spring, providing sufficient space for the insertion rod. After the insertion rod disengages from the positioning hole, the mosquito net panel and mosquito net can be easily removed from the fixed frame for cleaning. This design greatly improves the convenience of installing and removing the mosquito net, simplifies the cleaning process, and ensures the long-term effective use of the mosquito net.

[0027] A type of prefabricated steel entrance door, such as Figure 1-4 As shown, the device includes a door frame body 10 and a door panel body 11. A vent 12 is provided on the upper surface of the door frame body 10. A ventilated door panel 13 is rotatably connected to the inner cavity of the vent 12 via a hinge. A fixed frame 14 is fixedly installed on the front wall of the door frame body 10. A mesh panel 15 is provided inside the fixed frame 14, and a mosquito net 16 is fixedly connected to the inner wall of the mesh panel 15. Installation grooves 17 are symmetrically provided on the side wall of the mesh panel 15 away from the door frame body 10. Two actuating plates 18 are respectively provided in the two installation grooves 17. Each of the two actuating plates 18 is equipped with a disassembly and assembly mechanism for disassembling and assembling the mosquito net 16. The disassembly and assembly mechanism includes a telescopic rod 19, a telescopic spring 20, and two insert rods 21. The position of the fixed frame 14 corresponds to the position of the vent 12. The inner wall of the fixed frame 14 is flush with the edge of the vent 12. The outer walls of the two actuating plates 18 are slidably connected to the inner wall of the mounting groove 17. The two ends of the telescopic rod 19 are fixedly connected to the wall surface of the two actuating plates 18 that are close to each other. The telescopic spring 20 is sleeved on the outside of the telescopic rod 19. The two insert rods 21 are fixedly connected to the wall surface of the two actuating plates 18 that are far from each other. The other ends of the two insert rods 21 extend through the mesh plate 15 to the outside of the mesh plate 15. The two insert rods 21 are slidably connected to the mesh plate 15. The fixed frame 14 is adapted to the mesh plate 15. The upper and lower inner walls of the fixed frame 14 are provided with positioning holes 22 corresponding to the insert rods 21. The positioning holes 22 are adapted to the insert rods 21.

[0028] The working principle of this utility model is as follows: When ventilation is needed, the ventilation door 13 can be opened. The mosquito net 16 effectively blocks mosquitoes from entering the room. When dust accumulates on the surface of the mosquito net 16 and needs to be cleaned, the operator only needs to push the two actuating plates 18 on the mounting slot 17 to bring them closer together, thereby squeezing the telescopic rod 19 and the telescopic spring 20, providing enough space for the insertion rod 21. After the insertion rod 21 is disengaged from the positioning insertion hole 22, the mosquito net 15 and the mosquito net 16 can be easily removed from the fixed frame 14 for cleaning. This design greatly improves the convenience of disassembling and assembling the mosquito net 16, simplifies the cleaning process, and ensures the long-term effective use of the mosquito net.
