[0002] In civil air defense engineering buildings, the safety of civil air defense engineering buildings is very important. Therefore, some beams or planes in civil air defense engineering buildings often need to add supporting structures. These supporting structures can increase the stability of the beams and planes, making civil air defense engineering buildings safer.

[0003] Existing support structures for civil air defense projects mostly use support rods for support, but the height of the support rods can usually only be roughly adjusted, and it is easy for the support rod height to fail to meet the standard when adjusting the support rod height. Therefore, a support structure for civil air defense projects is needed that can not only quickly and roughly adjust the support rod height, but also finely adjust the support height. Utility Model Content

[0004] To this end, the utility model provides a civil air defense engineering support structure, which uses a support adjustment mechanism to solve the problem that the height of the support rod can usually only be roughly adjusted, and it is easy for the height of the support rod to fail to meet the standard when adjusting the height of the support rod.

[0009] Preferably, the trapezoidal block passes through the side hole and is slidably connected to the side hole.

[0010] Preferably, one end of the trapezoidal block extends into the height adjustment hole and is slidably connected to the height adjustment hole.

A support and adjustment component is provided inside the support seat 4, and the support and adjustment component includes a rotating shaft 7, which is arranged at the bottom of the support seat 4 and is slidably connected to the bottom of the support seat 4, and a gear 8 is fixedly sleeved on the outside of the rotating shaft 7. Support and adjustment gears are provided on both sides of the gear 8. The support and adjustment unit includes a rack 9, which is meshed with the gear 8, and a connecting plate 10 is fixedly connected to the top of the rack 9, and a trapezoidal block 11 is fixedly provided on one side of the connecting plate 10, and a spring 12 is fixedly connected between the two connecting plates 10;

[0028] In this embodiment, in order to achieve the purpose of coarse and fine adjustment of the height of the movable support rod 15, during coarse adjustment, the movable support rod 15 is lifted upward, and the movable support rod 15 moves and drives the top plate 17 to move, so that the top plate 17 is close to the support. At the same time, when the movable support rod 15 moves, the threaded rod 13 is pulled to move by the threaded sleeve 14, and the threaded rod 13 moves and pulls the support seat 4 to move, and the support seat 4 moves and drives the trapezoidal block 11 to move. When the trapezoidal block 11 moves, the inclined surface cooperates with the fixed sleeve 2 and the height adjustment hole 3, so that there is no obstruction when the top plate 17 moves upward, which is convenient for raising the position of the top plate 17 and convenient for coarse adjustment of the height of the top plate 17. During fine adjustment, the rotating wheel 16 is rotated, and the rotating wheel 16 drives the movable support rod 15 to rotate. The rotation of the movable support rod 15 is connected with the threaded sleeve 14 and the threaded rod 13 through the threaded connection, so that the movable support rod 15 moves longitudinally, and then the height of the top plate 17 is finely adjusted. Through the cooperation of coarse and fine adjustment, the accuracy of the support height of the top plate 17 is improved;

[0029] Among them, in order to achieve the purpose of facilitating the lowering of the height of the top plate 17, the present device adopts the following technical solutions: the connecting plate 10 is arranged inside the support seat 4 and is slidably connected to the support seat 4, the bottom of the connecting plate 10 passes through the obstacle avoidance groove 6 and is slidably connected to the obstacle avoidance groove 6, the trapezoidal block 11 passes through the side hole 5 and is slidably connected to the side hole 5, one end of the trapezoidal block 11 extends into the height adjustment hole 3 and is slidably connected to the height adjustment hole 3, the trapezoidal block 11 inside the height adjustment hole 3 is pushed so that 11 is moved out of the height adjustment hole 3, the trapezoidal block 11 moves through the connecting plate 10 so that the spring 12 contracts, and at the same time, when the connecting plate 10 moves, the rack 9 and the gear 8 cooperate to make the trapezoidal blocks 11 on both sides move synchronously relative to each other, so as to simultaneously release the restriction on the downward movement of the support seat 4 inside the fixed sleeve 2, thereby improving the convenience during use;

[0030] Among them, in order to achieve the purpose of rapid fine adjustment, the present device adopts the following technical scheme: the threaded sleeve 14 is sleeved on the outside of the threaded rod 13 and is connected to the threaded rod 13 by a thread, the threaded sleeve 14 is arranged inside the fixed sleeve 2 and is slidably connected to the fixed sleeve 2, the bottom of the movable strut 15 extends into the fixed sleeve 2 and is slidably connected to the fixed sleeve 2. During fine adjustment, the movable strut 15 is rotated by the rotating wheel 16, and the movable strut 15 rotates through the threaded connection between the threaded sleeve 14 and the threaded rod 13 to make the movable strut 15 move longitudinally, thereby finely adjusting the height of the top plate 17.

[0031] The use process of the utility model is as follows: when using the utility model, during rough adjustment, the movable support rod 15 is lifted upward, and the movable support rod 15 moves to drive the top plate 17 to move, so that the top plate 17 is close to the support. At the same time, when the movable support rod 15 moves, the threaded rod 13 is pulled to move through the threaded sleeve 14, and the threaded rod 13 moves to pull the support seat 4 to move, and the support seat 4 moves to drive the trapezoidal block 11 to move. When the trapezoidal block 11 moves, the inclined surface cooperates with the fixed sleeve 2 and the height adjustment hole 3 to make the trapezoidal block 11 slide toward the inside of the support seat 4, and the trapezoidal block 11 moves through the connecting plate 10 to make the spring 12 contract, so that there is no obstruction when the top plate 17 moves upward, which is convenient for raising the position of the top plate 17 and facilitating adjustment. The height of the top plate 17 is roughly adjusted. When the trapezoidal block 11 moves to the appropriate position, the trapezoidal block 11 corresponds to the height adjustment hole 3 at the corresponding position, and the contracted spring 12 uses the elastic force to make the connecting plate 10 drive the trapezoidal block 11 to pop out, so that the trapezoidal block 11 is inserted into the height adjustment hole 3, preventing the support seat 4 from descending inside the fixed sleeve 2, thereby improving the stability of the top plate 17 when supporting. During fine adjustment, the movable support rod 15 is rotated by the rotating wheel 16, and the movable support rod 15 rotates through the threaded connection between the threaded sleeve 14 and the threaded rod 13, so that the movable support rod 15 moves longitudinally, thereby finely adjusting the height of the top plate 17. Through the coordination of coarse and fine adjustments, the accuracy of the support height of the top plate 17 is improved.
