Description

A kind of closed guard gate

Technical field

The utility model is related to Technology for Civil Air Defence Projects field, more particularly to a kind of closed guard gate.

Background technology

Civil air defense constructions and installations is typically all manufacturing products for both peacetime and wartime us engineering, usually has substantial amounts of personnel and equipment to come in and go out, wartime requirement is closed The closed guard gate of gateway, prevents shock wave and poison gas from entering inside civil air defense constructions and installations.

Existing is by rotating locking handwheel, to open closed guard gate, when rotating locking handwheel, mainly without threshold closed guard gate It is that, by the frictional force between human hand and locking handwheel to drive locking hand wheel rotating, human hand grips easy during locking hand wheel rotating Skid so that more time-consuming when driving locking handwheel.

Utility model content

The people of skidding occurs when being to provide a kind of reduction operating personnel's blocks rotation handwheel for the purpose of this utility model Anti- door.

Above-mentioned technical purpose of the present utility model technical scheme is that：

A kind of closed guard gate, including locking handwheel, the locking handwheel include center disk, coaxially set with the center disk Outer shroud, the connection outer shroud and some connecting rods of the center disk put, the center disk and the connecting rod are equal Set to be hollow, the connecting rod connects the center disk, the side wall of the outer shroud is provided with along the pitman shaft to setting Put and be communicated in be coaxially arranged with the first through hole of the connecting rod, the center disk on gear, the gear and be engaged with Some racks being inserted in respectively in the connecting rod, the rack coordinates with the connecting rod gap, and the gear axis are worn The center disk is rotationally connected with provided with one and one end wears out rotating shaft outside the center disk.

By using above-mentioned technical proposal, rotating shaft is to drive after pinion rotation, pinion rotation, the rack being engaged with Slid towards first through hole, until a part for rack is stretched out outside first through hole, human hand is located at first through hole by gripping Outer rack, it is more time saving and energy saving to promote locking hand wheel rotating by applying thrust to rack, while reducing the skidding of hand Phenomenon；After door is opened, rotating shaft can be rotated in the opposite direction, rack is returned in connecting rod, realize hiding for rack, together When, by the setting of rack, people's center of rotation disk can be made more laborsaving, it is easy to operate.

It is of the present utility model to be further arranged to：The madial wall of the connecting rod is provided with the first limited block, the rack Side wall be provided with and be used to contradict the locating piece of first limited block, when the locating piece contacts at first limited block When, the rack is passed outside the first through hole.

By using above-mentioned technical proposal, when locating piece contacts at the first limited block, a part for rack stretches out first Outside through hole, gripped for human hand to promote locking handwheel to rotate, so that positioning is realized, while the setting of the first limited block, it is to avoid tooth Bar is displaced outwardly again, so as to cause rack to leave the engagement range of gear so that rack can not be returned in connecting rod again.

It is of the present utility model to be further arranged to：The madial wall of the connecting rod is provided with the contradicted for the locating piece Two limited blocks, when the locating piece contacts at second limited block, the rack is returned in the connecting rod.

By using above-mentioned technical proposal, the setting of the second limited block provides positioning for rack, when locating piece contradicts second During limited block, rack is retracted into connecting rod, while one end when avoiding the rack from retracting away from first through hole and adjacent rack Collide.

It is of the present utility model to be further arranged to：It is provided with the center disk and contacts at the rack away from the gear End face the 3rd limited block.

By using above-mentioned technical proposal, the setting of the 3rd limited block is in order that rack is engaged in gear all the time, it is to avoid Hand promote rack with drive locking handwheel rotate when, rack shifts because of unbalance stress, the 3rd limited block limitation tooth Bar is offset towards the direction away from gear, rack and pinion is kept meshing relation.

It is of the present utility model to be further arranged to：The one end of the rack away from the gear is smooth section, described smooth Section is cylinder.

By using above-mentioned technical proposal, by setting smooth section, rack is slid out after first through hole, and smooth section is located at the Outside one through hole, facilitate human hand to grip, it is to avoid human hand is held on the tooth on rack, easily scratch skin on hand；By smooth section Cylinder is set to, cylindrical side wall does not have seamed edge, and the grip feeling of hand is more comfortable.

It is of the present utility model to be further arranged to：One end that the rotating shaft wears out the center disk is fixedly connected with and held Disk is held, the side wall of the gripping disk is provided with the gripping groove that some confession fingers are placed.

By using above-mentioned technical proposal, the contact area of disk, increase hand and rotating shaft, convenient operation are gripped by setting Personnel's drive shaft rotates；When rotation grips disk, finger is embedded in gripping groove, two madial walls of gripping groove are limited to finger Position effect, it is to avoid finger slippage, it is more time saving and energy saving.

In summary, the utility model has the advantages that：By the cooperation of gear and rack, when opening the door, rotation Rotating disk stretches out rack outside first through hole, and human hand is by gripping the rack stretched out outside first through hole, to promote locking handwheel Rotation, it is time saving and energy saving, reduce the skidding of hand, after door is opened, gear can be rotated in the opposite direction, rack is returned to In connecting rod, hiding for rack is realized；By setting locating piece and the first limited block, when locating piece contacts at the first limited block When, a part for rack is stretched out outside first through hole, is gripped for human hand to promote locking handwheel to rotate, so as to realize positioning, simultaneously The setting of first limited block, it is to avoid rack is displaced outwardly again, so as to cause rack to leave the engagement range of gear so that rack without Method is slid next time again.
