Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

As shown in fig. 1, 2, 3 and 4, the civil air defense door supporting device comprises a door frame 1 and a door plate 2, and is characterized in that a supporting shaft 3 is fixedly mounted on the door frame 1, the door plate 2 is rotatably mounted on the supporting shaft 3, a hollow groove 4 is formed in one downward end of the door plate 2, a rotating shaft 5 rotatably mounted on the door plate 2 is arranged in the hollow groove 4 and rotatably perpendicular to the supporting shaft 3, one end of the rotating shaft 5, facing the supporting shaft 3, extends out of the door plate 2 and is fixedly provided with a driven bevel gear 6, a driving bevel gear 7 meshed with the driven bevel gear 6 is fixed on the supporting shaft 3, a coaxial worm 8 is fixedly connected to one end, far away from the supporting shaft 3, of the rotating shaft 5, the worm 8 is rotatably mounted on the door plate 2, a turbine 9 is meshed below the worm 8, the turbine 9 is rotatably mounted on the door plate 2, and a supporting component is fixedly mounted, the supporting component includes and all offers the sleeve 10 of through-hole with terminal surface about turbine 9 fixedly connected with, the inside one end and the inside fixed connection of sleeve 10 that are equipped with turbine 9 of a plurality of lead screws 11 and lead screw 11 and keep away from turbine 9 that are equipped with of sleeve 10, the inside sliding connection of sleeve 10 has backup pad 22, rotate quantity and the position of installing a plurality of gear nuts 12 and gear nut 12 in backup pad 22 and a plurality of lead screw 11 one-to-one, lead screw 11's the other end pass backup pad 22 and with gear nut 12 between threaded connection, be fixed with supporting leg 13 in the one side that deviates from gear nut 12 in backup pad 22, supporting leg 13 is kept away from the one end of backup pad 22 and is stretched out sleeve 10 and downwardly extending, backup pad 22 rotates in the one side that deviates from supporting leg 13 and installs drive gear 14 and a plurality of gear nuts 12 between intermeshing, be fixed with on the one side that deviates from backup pad 22 A rotating rod 16 is horizontally arranged, an operating rod 17 is arranged on the rotating rod 16, one end of the operating rod 17, which is close to the twisting gear 15, is fixed with a bayonet lock meshed with the twisting gear 15, and the other end of the operating rod 17 extends to one side far away from the twisting gear 15.

This device is when using, and figure 1 is the state of people's air defense door when closing, and supporting leg 13 is horizontal position and pivot 5 parallel this moment, and supporting leg 13 can not lead to the fact the influence to closing of people's air defense door, sets up the subassembly of supporting leg 13 in dead slot 4 of door plant 2 below simultaneously, can not exert an influence to 2 overall structure of door plant, can not lead to the fact the influence to the protection quality of people's air defense door simultaneously yet. When the people's air defense door is opened, door plant 2 rotates and fixes initiative conical gear 7 on back shaft 3 motionless along back shaft 3, rotate rather than the driven conical gear 6 of meshing installation, it rotates to drive pivot 5, pivot 5 rotates and drives and rotate 5 fixed connection's of pivot worm 8, worm 8 rotates and drives the turbine 9 of meshing and rotate, turbine 9 anticlockwise rotation, supporting leg 13 of being connected with turbine 9 follows the rotation, make supporting leg 13 rotate to with 5 vertically positions of pivot, thereby make pivot 5 reach the effect of supporting the people's air defense door. Can effectually prevent that the articulated department of door plant 2 from causing the damage under the state that people's air defense door normally opened to guarantee that door plant 2 still can keep normal closing after long-time keeping open mode, can not cause unable the closing or produce not inclosed condition and appear. Adopt 8 worm wheel 9 structures of worm simultaneously and make 8 worm wheels that drive 9 rotate, because of it has reverse self-locking function, so can guarantee that supporting leg 13 can not produce the skew when supporting, can be stable support door plant 2. People's air defense door can install in the environment of difference when the installation, and different environment will make door plant 2 highly can't keep unanimous apart from ground, even door plant 2 integrative door plant of roof beam mountain also can be because the reason of construction can't guarantee when door plant 2 is opened that door plant 2 is apart from ground apart from the distance unanimous, so supporting leg 13 still can't guarantee door plant 2 if keep fixed distance can not receive the damage. The supporting leg 13 of the device passes through the sleeve 10 and is fixed on a supporting plate 22 which is connected with the sleeve 10 in a sliding way, a plurality of screw rods 11 are arranged in the sleeve 10, the screw rods 11 pass through the supporting plate 22, gear nuts 12 are connected on the screw rods 11 in a threaded way, the gear nuts 12 are rotatably arranged on the supporting plate 22, a driving gear 14 is rotatably arranged on the supporting plate 22, the driving gear 14 can drive the gear nuts 12, so that the gear nuts 12 can synchronously rotate, a twisting gear 15 is fixed on the driving gear 14, a rotating rod 16 is rotatably arranged on the twisting gear 15, an operating rod 17 is fixed on the rotating rod 16, a bayonet lock on the operating rod 17 can be clamped in teeth of the twisting gear 15, at the moment, the purpose of rotating the twisting gear 15 can be achieved by rotating the operating rod 17, the twisting gear 15 rotates to drive the driving gear 14 to rotate, the driving gear 14 drives the gear nuts 12 to rotate, so that the supporting plate, thereby the supporting leg 13 fixed on the supporting plate 22 reaches the purpose of moving up and down, thereby the supporting leg 13 can be adjusted to better support the door panel 2. Adopt 11 structures of lead screw itself to have self-locking function, can guarantee that supporting leg 13 can not produce when supporting and reciprocate, better support door plant 2.

The number of the plurality of screw rods 11 is four, and universal wheels 18 are mounted at one ends, far away from the sleeve 10, of the supporting legs 13.

Because the civil air defense door is generally comparatively thick and heavy, so need set up lead screw 11 into a plurality ofly and position four, can be better support door plant 2, more stable when supporting simultaneously. Set up universal wheel 18 in the below of supporting leg 13, when people's air defense door needs urgent closing, can directly close, because universal wheel 18's effect, so the slip that produces when closing can be fine make supporting leg 13 pack up, reduced the operation degree of difficulty when closing people's air defense door, speed when improving to close avoids producing danger.

A cylinder 19 is fixed below the rotating rod 16, the operating rod 17 penetrates through the cylinder 19, a baffle plate 20 is fixed on the operating rod 17, the baffle plate 20 can only move in the cylinder 19, a spring 21 is sleeved on the operating rod 17, and one end of the spring 21 and the other end of the baffle plate 20, which is in contact with the spring 21, are fixedly connected with the front of the cylinder 19.

The operating rod 17 can drive the twisting gear 15, the operating rod 17 needs to stretch and retract to operate when the operating rod is driven, the operating rod 17 can be operated conveniently, the spring 21 can save working strength, meanwhile, the pressure of the operating rod 17 when the twisting gear 15 is operated can be increased, and the operating rod 17 is guaranteed not to slip, so that danger is avoided. The operating rod 17 can be lengthened, the gear is prevented from rusting due to the reason of immobility for a long time and cannot normally operate, the length of the operating rod 17 is increased, operation can be easily performed by utilizing the lever principle, and a large amount of labor is saved.

The above-mentioned embodiments are not intended to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art without departing from the design concept of the present invention should be included in the protection scope defined by the claims of the present invention.
