[0002] Civil air defense door frames are door frames used in civil air defense projects, typically at the entrances and exits of air defense facilities such as air raid shelters and basements. These door frames typically feature special designs and functions to ensure safe and rapid entry and exit of personnel in emergency situations. Installation of these door frames typically requires the installation of support agents. Support frames for civil air defense doors and windows are structures used to support and secure them, and their design and installation are crucial to ensuring their stability and safety.

A support frame is fixedly installed in the civil defense door frame body, and the support frame includes a positioning member, the positioning member is passed through the locking through hole, and one end of the positioning member is located between the two vertical plates, and a synchronization rod is fixedly connected to the end of the positioning member located between the two vertical plates, and a first support rod perpendicular to the synchronization rod is fixed to the lower end of the synchronization rod, and two second support rods are connected to the positioning member, and the second support rods are respectively located on both sides of the civil defense door frame body, and the end of the second support rod away from the positioning member is fixedly connected to the first support rod. It can firmly support the civil defense door frame, and it is not easy for the verticality and horizontality of the civil defense door frame to fail to meet the requirements. However, in actual use, the device supports and fixes the main body through the first support rod and the second support rod. However, when supporting the ground with a slope, it cannot be adjusted well, and thus cannot meet the use requirements of the device. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a civil defense door frame installation support frame, which aims to improve the problem that when supporting the sloped ground, it cannot be adjusted well and thus cannot meet the use requirements of the device.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a civil defense door frame mounting support frame, comprising an outer frame and two adjusting plates, the left and right ends of the front side of the outer frame are rotatably connected to a rotating column, the front sides of the two rotating columns are fixedly connected to the rotating plate, and a convex groove is provided on the side away from the two rotating plates, and the middle parts of the left and right sides of the outer frame are fixedly connected to a threaded locking block, the inner walls of the two threaded locking blocks are threadedly connected to a threaded rotating column, and the adjacent sides of the two threaded rotating columns are fixedly connected to a limiting column, and the outer walls of the two limiting columns are respectively slidably connected to the corresponding convex grooves, and the front sides of the two adjusting plates are equidistantly fixed with multiple adjusting locking plates, and the adjacent sides of the two rotating plates are rotatably connected to a rotating page through a torsion spring, and the outer wall of the rotating page is fixedly connected to the support plate, and the left and right bottom sides of the outer frame are provided with a mounting mechanism.

[0006] Through the above technical solution, the angles of the two rotating plates can be adjusted, so that the threaded screw and the corresponding adjustment locking plate are rotationally locked, and then the ground with different slopes can be adjusted, so that the support plate can support the ground under the rotation connection of the torsion spring.

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] Reference Figure 1 and Figure 2The left and right sides of the outer frame 1 are fixedly connected with a screw thread locking block 6, and the inner walls of the two screw thread locking blocks 6 are threadedly connected with a screw thread rotating pin 7. The adjacent sides of the two screw thread rotating pins 7 are fixedly connected with a limiting pin 8. The outer walls of the two limiting pins 8 are respectively slidably connected with the corresponding convex grooves 5. The front sides of the two adjusting plates 9 are equidistantly fixed with a plurality of adjusting locking plates 10. The adjacent sides of the two rotating plates 4 are rotatably connected with a rotating page 11 through a torsion spring. The outer wall of the rotating page 11 is fixedly connected to the support plate 12. The left and right bottom sides of the outer frame 1 are provided with a mounting mechanism 2.

[0038] Specifically, by rotating the two threaded pins 7, the locking state between them and the threaded locking block 6 is released. The purpose of this step is to allow the threaded pin 7 to slide freely inside the convex groove 5. When the locking state is released, we can slide the threaded pin 7 to make it move smoothly inside the convex groove 5 together with the limiting column 8. During the sliding process, by adjusting the angles of the two flip rotating plates 4, we can make it reach the angle we need. The implementation of this step depends on the special design of the flip rotating plate 4, which allows us to adjust its angle within a certain range to adapt to different ground slopes. When the angle of the flip rotating plate 4 is adjusted, we slide it again The threaded screw 7 is screwed into the corresponding adjustment locking plate 10. Then, we rotate the threaded screw 7 to form a rotation lock between it and the adjustment locking plate 10, thereby fixing the position of the two rotating plates 4. At this time, the entire device has completed the preliminary adjustment and fixation. Next, when the device is affected by the slope of the ground, the turning page 11 and the support plate 12 are connected by torsion spring rotation, which can automatically change the angle. This change enables the device to better adapt to the slope of the ground, thereby achieving a supporting effect. In this way, we can accurately adjust the support for the ground with different slopes, avoiding the normal use of the door frame affected by changes in the ground slope.

[0040] The two locking plates 201 on the rear side of the two adjustment plates 9 are respectively engaged with the corresponding locking grooves 204. After the engagement is completed, the multiple spring locking plates 205 are released. At this time, the fixing plate 206 on the front side will be engaged with the locking groove 202 on the rear side of the corresponding locking plate 201 and locked. This step further ensures the stability of the component installation, making it less likely for the component to loosen or fall off during use. If disassembly is required, only the reverse operation steps need to be followed. This installation and disassembly method not only simplifies the operation process, but also reduces the difficulty of operation, making it easy for the operator to cope with it. In addition, this locking mechanism also has the advantage of convenient transportation and handling. Due to the simple installation and disassembly process, we can quickly disassemble the components when needed for easy transportation and handling, which greatly saves time and labor costs and improves work efficiency.
