Description

Effectual protective airtight door shocks resistance

Technical Field

The utility model relates to a protective sealing door technical field especially relates to a protective sealing door that shock resistance is effectual.

Background

The large civil air defense engineering generally comprises a plurality of protection units, and in order to ensure that the loss of the protection function of one protection unit does not influence the exertion of the protection functions of other protection units in wartime, a communication port of each protection unit is provided with a protective airtight door capable of bearing in two directions respectively.

However, the existing protective door has certain defects:

1. the airtight door can lead to airtight door to cause the damage together with the door frame under meetting great impact force's effect for current airtight door has the relatively poor condition of effect of anti-impact force, causes the cycle of changing airtight door shorter, increases the cost of changing.

2. Meanwhile, when the airtight door is impacted, the impacting force can be completely concentrated on the airtight door, the impact force cannot be removed and converted, the airtight door can deform, and the airtight door is not tightly closed.

Disclosure of Invention

The utility model discloses aim at solving prior art's not enough, and provide an effectual protective airtight door shocks resistance.

The utility model discloses a realize above-mentioned purpose, adopt following technical scheme:

a effectual protection airtight door shocks resistance, including the door frame, the inside one side of door frame articulates there is the airtight door, the inside of airtight door is provided with the dead slot, the both sides at the inside top of dead slot are connected with the threaded rod through the bearing, the top fixedly connected with gear in the threaded rod outside, the outside threaded connection of threaded rod has the balancing weight, the inside top of balancing weight is seted up threaded hole, threaded rod bottom spiro union in threaded hole, the inside both sides of dead slot slide and are provided with the rack, and the rack is two sets of with the gear engagement that corresponds the both ends fixedly connected with crashproof board of rack, be provided with the spring between crashproof board and the airtight door.

Preferably, the gear is located between two sets of racks, and two sets of racks are arranged oppositely, so that the racks are driven to rotate conveniently.

Preferably, two groups of limiting sleeve blocks are fixedly connected to the middle positions of the two ends of the inner portion of the empty groove to limit the threaded rod.

Preferably, one side of the anti-collision plate opposite to the airtight door is respectively provided with a piston rod and a piston cylinder, and a piston on the piston rod is slidably arranged in the piston cylinder.

The beneficial effects of the utility model are that:

1. be provided with the crashproof board through one side at the sealed door, when the sealed door received the striking, the power of striking can all concentrate on the crashproof board, can promote the crashproof board and remove, and elasticity through the spring can carry out preliminary buffering to the impulsive force, and the piston rod slides in piston barrel is inside simultaneously, extrudees the gas of the inside of piston barrel, and gas can block the continuation removal of crashproof board.

2. Simultaneously, the anti-collision plate can drive the rack to move when moving, and the gear drives the threaded rod to rotate through the meshing of the rack and the gear, and the threaded rod drives the balancing weight to move upwards through the effect of the threaded hole, so that the force applied to the anti-collision plate is converted into the upward force of the balancing weight.

Drawings

Fig. 1 is a schematic structural view of the present invention;

fig. 2 is a top view of the anti-collision plate of the present invention;

fig. 3 is a front view of the present invention.

In the figure: 1-a door frame; 2-a gear; 3-a sealed door; 4-empty groove; 5-a rack; 6-a balancing weight; 7-a threaded rod; 8-a threaded hole; 9-a crash-proof plate; 10-a spring; 11-a piston cylinder; 12-a piston rod.

The following detailed description will be made with reference to the accompanying drawings in conjunction with embodiments of the present invention.

Detailed Description

The invention will be further explained with reference to the following figures and examples:

as shown in fig. 1-3, a protective airtight door with good impact resistance effect, including door frame 1, door frame 1 is inside one side-hinged airtight door 3, airtight door 3's inside is provided with dead slot 4, the both sides at the inside top of dead slot 4 are connected with threaded rod 7 through the bearing, the top fixedly connected with gear 2 in the threaded rod 7 outside, the outside threaded connection of threaded rod 7 has balancing weight 6, threaded hole 8 is seted up at the inside top of balancing weight 6, the bottom of threaded rod 7 extends to the inside of threaded hole 8, threaded connection between threaded rod 7 and the threaded hole 8, the inside both sides of dead slot 4 slide and are provided with rack 5, rack 5 meshes with corresponding gear 2, gear 2 is located between two sets of rack 5, two sets of rack 5 set up relatively, the both ends fixedly connected with crashproof board 9 of two sets of rack 5, be provided with spring 10 between crashproof board 9 and the airtight door 3.

Furthermore, two groups of limit sleeve blocks are fixedly connected to the middle positions of the two ends in the empty groove 4.

Furthermore, a piston rod 12 and a piston cylinder 11 are respectively arranged on one side of the anti-collision plate 9 opposite to the sealed door 3, and a piston on the piston rod 12 is arranged in the piston cylinder 11 in a sliding manner.

The working principle is as follows: at first crashproof board 9 is receiving the striking, crashproof board 9 removes and drives rack 5 and remove, rack 5 drives gear 2 and rotates, gear 2 drives threaded rod 7 and rotates, threaded rod 7 drives balancing weight 6 rebound through screw hole 8, make crashproof board 9 when receiving the striking, the displacement is little, prevent that airtight door 3 from receiving the impact under the effect of external force, it causes deformation to receive the impact, extrude spring 10 simultaneously, the elasticity that produces cushions the impact, piston rod 12 drives the piston and removes in the inside of piston barrel 11 simultaneously, to the inside gas compression of piston barrel 11, play the cushioning effect, further reduce the impact force.
