DETAILED DESCRIPTION

[0024] As Figures 1-7 shown, the utility model provides a technical scheme: a civil air defence door frame mounting support, including bottom plate 1, bottom plate 1 top fixed mounting has support frame 2, support frame 2 top fixed mounting has support block 3, support block 3 outside set up for improving the fixed assembly 4 and movable assembly 5 of civil air defence door frame mounting stability, and movable assembly 5 includes: control motor 51, bevel gear one 52, bevel gear two 53, threaded rod 54, telescopic rod 55, fixed spring 56, fixed block 57, clamping block 58, movable spring 59, toothed plate 510, rotating shaft 511, reciprocating screw 512, limiting plate 513, insert strip 514.

[0025] The control motor 51 is fixedly installed on the top of the bottom plate 1. The control motor 51 is started to drive the bevel gear one 52 to rotate in the inside of the support block 3. When the bevel gear one 52 rotates, the bevel gear two 53 rotates, and the threaded rod 54 rotates. The control motor 51 output shaft surface is fixedly installed with the bevel gear one 52. The bevel gear one 52 is rotatably connected in the inside of the support block 3. The bevel gear one 52 outside is engaged with the bevel gear two 53. The bevel gear two 53 outside is fixedly installed with the threaded rod 54. When the extension rod 55 moves, the fixed block 57 and the clamping block 58 slide with the moving direction of the extension rod 55, so that the clamping block 58 is clamped on the surface of the civil defense door frame to be fixed. The threaded rod 54 penetrates through the support block 3. The threaded rod 54 surface is screw connected with the extension rod 55. The extension rod 55 is fixedly installed with the fixed spring 56 in the inside. The extension rod 55 surface is fixedly installed with the fixed block 57. The fixed block 57 is slidably connected with the clamping block 58 in the inside. When the clamping block 58 is clamped on the surface of the civil defense door frame, the extension rod 55 is resisted by the civil defense door frame to drive the extension rod 55 to shrink. When the extension rod 55 shrinks, the tooth plate 510 on the top of the fixed block 57 moves to the outer wall close to the limiting plate 513. The clamping block 58 is fixedly installed with the movable spring 59 on the inside. The clamping block 58 is fixedly installed with the tooth plate 510 on the top. The support block 3 outer wall is rotatably connected with the rotating shaft 511. The rotating shaft 511 is fixedly installed with the reciprocating wire rod 512 in the inside. The reciprocating wire rod 512 surface is screw connected with the limiting plate 513. The limiting plate 513 is slidably connected in the inside of the rotating shaft 511. The limiting plate 513 surface is fixedly installed with the plug strip 514. When the tooth plate 510 moves, the plug strip 514 on the surface of the limiting plate 513 is penetrated, so that the plug strip 514 is inserted on the surface of the tooth plate 510 to be limited. The impact force generated during the concrete pouring during the installation of the civil defense door frame is prevented. The connecting part between the support and the door frame is prone to looseness. The stability and fixing effect of the civil defense door frame installation are improved.

[0026] The fixed assembly 4 comprises a resisting plate 41, which resists the sliding of the sliding block 43 in the inside of the short plate 42 when the resisting plate 41 moves to the surface of the sliding block 43, and drives the rotation of the rotating shaft 511 when the sliding block 43 slides, thereby driving the rotation of the reciprocating lead screw 512. The resisting plate 41 is fixedly installed at the inner side of the fixed block 57. The outer side of the limiting plate 513 is fixedly installed with a resisting block 46, which resists and limits the shaking of the civil defense door frame, and the positioning block 47 is used for second clamping of the clamping block 58, so that the clamping effect of the clamping block 58 is not reduced due to the shaking of the civil defense door frame, the civil defense door frame is prevented from falling, and the safety and fixity during installation of the civil defense door frame are improved. The outer side of the limiting plate 513 is fixedly installed with the positioning block 47. The outer side of the supporting block 3 is fixedly installed with the short plate 42. The sliding block 43 is slidably connected in the inside of the short plate 42. The connecting spring 44 is fixedly installed in the inside of the short plate 42. The sliding block 43 is fixedly installed with the connecting spring 44. The sliding block 43 is fixedly installed with the sliding rod 45. The sliding rod 45 is slidably connected to the surface of the rotating shaft 511. The two groups of movable assemblies 5 are symmetrically arranged about the center line of the supporting block 3. The recess 580 is arranged at the inner side of the clamping block 58, so that the limiting effect of the clamping block 58 on the civil defense door frame is improved. The arc-shaped groove 5110 is arranged on the surface of the rotating shaft 511, so that the rotation of the rotating shaft 511 is driven by the sliding of the sliding rod 45.

[0027] When the civil defense door frame mounting bracket is used, the control motor 51 is started to drive the conical gear one 52 to rotate in the inside of the supporting block 3. The rotation of the conical gear one 52 drives the rotation of the conical gear two 53. The rotation of the conical gear two 53 drives the rotation of the threaded rod 54 and the movement of the telescopic rod 55 away from the outer side of the supporting block 3. The movement of the telescopic rod 55 drives the sliding of the fixed block 57 and the clamping block 58 in the moving direction of the telescopic rod 55, so that the clamping block 58 is clamped on the surface of the civil defense door frame for fixation. When the clamping block 58 is clamped on the surface of the civil defense door frame, the telescopic rod 55 is retracted under the resistance of the civil defense door frame. The retraction of the telescopic rod 55 drives the movement of the toothed plate 510 on the top of the fixed block 57 towards the outer wall of the limiting plate 513. The movement of the toothed plate 510 is penetrated by the fixed insertion strip 514 on the surface of the limiting plate 513, so that the insertion strip 514 is inserted into the surface of the toothed plate 510 for limitation. The insertion strip 514 prevents the connection part between the bracket and the door frame from being loose due to the impact force generated during concrete pouring during installation of the civil defense door frame, thereby improving the stability and fixation effect of the civil defense door frame installation.

[0028] When the door frame of the civil air defense door shakes during installation, the shaking force will drive the abutting plate 41 to move towards the surface close to the sliding block 43, when the abutting plate 41 moves to the surface of the sliding block 43, the sliding block 43 will abut and slide in the short plate 42, when the sliding block 43 slides, it will drive the slide rod 45 to slide on the surface of the rotating shaft 511, thereby driving the rotating shaft 511 to rotate, when the rotating shaft 511 rotates, it will drive the reciprocating screw rod 512 to rotate, when the reciprocating screw rod 512 rotates, it will drive the positioning block 47 and the abutting block 46 to move towards the inner side close to the fixed block 57, thereby abutting and limiting the civil air defense door frame during shaking through the abutting block 46, and secondarily clamping the clamping block 58 through the positioning block 47, preventing the clamping effect of the clamping block 58 from being reduced due to the shaking of the civil air defense door frame, so that the civil air defense door frame is prevented from falling, and the safety and fixity during installation of the civil air defense door frame are improved.

[0029] The above has made a detailed description of the utility model in general, but some modifications or improvements can be made on the basis of the utility model, which is obvious to those skilled in the art. Therefore, the modifications or improvements without departing from the spirit of the utility model are within the protection scope of the utility model.
