Description
Technical field
The utility model belongs to civil air defense constructions and installations field, particularly a kind of connector for people's air defense activity threshold.
Background technology
Civil air defense constructions and installations oral area is the inevitable passage of the inside and outside contact of engineering, is that civil air defense constructions and installations the most easily exposes and subjects to most to oppose the position destroyed, the thus inevitable significant points being also civil air defense constructions and installations and safeguarding.Closed guard gate is the important protective equipment in access.Closed guard gate's threshold divides fixing threshold and activity threshold: directly exceed shaping ground when fixing threshold is and breaks concrete; Activity threshold is that threshold flushes with ground in order to every day use aspect, and ground finished surface is with high, and threshold is in place wartime.
Activity threshold closed guard gate was in place for inspecting for acceptance before civil air defense constructions and installations is checked and accepted, until examination by after, owner by activity threshold dismounting to facilitate every day use.But the maintenance management at ordinary times of people's air defense activity threshold but seldom can put in place, specifically has following problem: 1, people's air defense activity threshold disassembles does not have effective shutoff to bolt hole, easily cause the shutoff of screw dust stratification; 2, civil air defense constructions and installations technical interior in summer is moist, the exposed easy corrosion of people's air defense activity threshold bolt hole in engineering; 3, not in place owing to safeguarding at ordinary times, the bolt causing closed guard gate's activity threshold to disassemble is lost.Above-mentioned 3 problems easily cause: 1, people's air defense activity threshold bolt hole blocking, and wartime, bolt cannot be screwed into; 2, people's air defense activity threshold bolt hole corrosion, wartime, bolt cannot be twisted firmly; 3, people's air defense activity threshold bolt is the safeguard component of the standardization of people's air defense safeguard factory, regularization, once lose, is difficult to find the bolt of applicable size to replace in the short time.If people's air defense activity threshold can not put in place in maintenance management, once conversion in wartime, will greatly have influence on the war readiness benefit of civil air defense constructions and installations.
Utility model content
The purpose of this utility model is for the problems referred to above, provides a kind of connector for people's air defense activity threshold, and after preventing people's air defense activity threshold from pulling down, bolt is lost, bolt hole corrosion and blocking.
The purpose of this utility model is achieved in that
For a connector for people's air defense activity threshold, comprise bolt and be embedded in the bolt sleeve of underground in advance, it is characterized in that:
Also comprise and be placed on metallic gasket on the screw rod of bolt and Cowhells packing ring;
The top of the hex bolts head of described bolt is provided with cross recess;
Described bolt sleeve comprises installing hole sleeve and accepting hole sleeve; The inwall of described installing hole sleeve is provided with internal thread and coordinates with the external screw thread of bolt, and the height of installing hole sleeve is not less than the height of screw rod; The internal diameter of described accepting hole sleeve is greater than external diameter maximum in hex bolts head, metallic gasket and Cowhells packing ring three, and it is highly greater than the summation of hex bolts head, metallic gasket and Cowhells packing ring three height; The bottom of described accepting hole sleeve and the top of installing hole sleeve are connected to form shoulder hole sleeve-shaped.
Wherein, the seal cover covered at accepting hole sleeve top is also comprised.
Wherein, described seal cover is mushroom, is made up of column connecting portion and arc surfaced top cover; The diameter of described column connecting portion equals the internal diameter of accepting hole sleeve; The basal diameter of described arc surfaced top cover is greater than the internal diameter of accepting hole sleeve.
The beneficial effects of the utility model are: after people's air defense activity threshold is pulled down, and this connector can install in-stiu encapsulation at threshold, prevents loss, and effectively prevent bolt hole corrosion and blocking simultaneously.

Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, set forth the utility model further.
As shown in Figure 1, a kind of connector for people's air defense activity threshold, comprises bolt 1, bolt sleeve 2, seal cover 3, metallic gasket 4 and Cowhells packing ring 5.
Metallic gasket 4 and Cowhells packing ring 5 are placed on the screw rod 12 of bolt 1.
As shown in Figures 2 and 3, the top of the hex bolts head 11 of bolt 1 is provided with cross recess 13.After in bolt 1 submerges bolt sleeve 2 completely, Phillips screwdriver is used to be back-outed by bolt 1 easily.
As shown in Figure 4 and Figure 5, bolt sleeve 2 comprises installing hole sleeve 21 and accepting hole sleeve 22.The bottom of accepting hole sleeve 22 and the top of installing hole sleeve 21 are connected to form shoulder hole sleeve-shaped.The inwall of installing hole sleeve 21 is provided with internal thread and coordinates with the external screw thread of bolt, and the height of installing hole sleeve 21 is not less than the height of screw rod 12.The internal diameter of accepting hole sleeve 22 is greater than external diameter maximum in hex bolts head 11, metallic gasket 4 and Cowhells packing ring 5 three, and it is highly greater than the summation of hex bolts head 11, metallic gasket 4 and Cowhells packing ring 5 three height.
As shown in Figure 6, seal cover 3, in mushroom, is made up of column connecting portion 31 and arc surfaced top cover 32.The diameter of column connecting portion 31 equals the internal diameter of accepting hole sleeve 22.The basal diameter of arc surfaced top cover 32 is greater than the internal diameter of accepting hole sleeve 22.For covering at the top of bolt sleeve 2, prevent dust stratification or water inlet in bolt sleeve 2, and its arc surfaced top cover 32 can prevent from tripping other people, improves safety.
When the utility model uses, first bolt sleeve 2 is embedded in underground.When needs people's air defense activity threshold 7 removed to facilitate pass in and out at ordinary times time, Cowhells packing ring 5, metallic gasket 4 are positioned in accepting hole sleeve 22 successively.Then, the screw rod 12 of bolt 1 is screwed in installing hole sleeve 21 through metallic gasket 4 and Cowhells packing ring 5 successively, till the top of the hex bolts head 11 of bolt 1 is lower than accepting hole sleeve 22 upper edge.Finally, seal cover 3 is covered on accepting hole sleeve 22.With this, bolt 1, metallic gasket 4 and Cowhells packing ring 5 and bolt sleeve 2 one_to_one corresponding are received, the situation effectively preventing each parts from losing because separately receiving occurs, and can also prevent dust stratification blocking or the situation because of corrosion of intaking in bolt sleeve 2 from occurring.
When people's air defense activity threshold 7 installed by needs, only seal cover 3 need be taken off, then with screwdriver, bolt 1 be tripped out, then metallic gasket 4 and Cowhells packing ring 5 are taken out successively.Then, be placed on the ground by people's air defense activity threshold 7, the installing hole of people's air defense activity threshold 7 is corresponding with bolt sleeve 2.Then, the screw rod 12 of bolt 1 overlaps upper metallic gasket 4 and Cowhells packing ring 5 from top to bottom successively, then tighten through stretching in installing hole sleeve 21 after the installing hole of people's air defense activity threshold 7 and packing ring 6 successively.So far, the fixing of people's air defense activity threshold 7 is completed.For making fixing more firm of people's air defense activity threshold 7, also can select to place accepting hole sleeve 22 in an external diameter with its quite, the packing ring 6 that the external diameter of internal diameter and screw rod 12 is suitable.
