Abstract
The utility model relates to a two-point locking type theft-proof cesspool cover. A gear and a gear rod are arranged on a cesspool cover, and the gear rod is expanded and contracted through rotating the gear arranged in a small hole arranged at the center of the surface of the cesspool cover. When the gear rod is expanded and contracted, the gear rod can extend into the lower edge of a station edge of a cesspool base, and can lock the cesspool cover. The cesspool cover can not be optionally taken out from the cesspool base, and inversely, the cesspool cover can be taken out. Because the utility model has simple structure, the purpose of the two-point locking type theft-proof cesspool cover can be obtained by slightly reforming the existing cesspool cover. The technology obviously overcomes the disadvantages of unreasonable and complex structure and easy pulling apart of the theft-proof cesspool cover of the prior art. The utility model is not only suitable for the antitheft of the cesspool, but also can be used for the locking of the manhole covers of a communication manhole mouth and other ground pit openings.
Description
The utility model belongs to urban ground engineering construction class, particularly a kind of 2 locking type Anti-theft cover for sewage well that are used for sink hole.
Effluent discharge was all discharged by underground pipeline during urban ground was built, every the street is equipped with several outfall, and block with well lid, well lid in the existing technology is in order to prevent artificial migration or to destroy and all adopt the locking way to be fixed, really played certain effect, but also there are many drawbacks, such as the cesspool cover of locking type, when opening, need to be equipped with fixed handle or special tool, well lid is also very easily opened by the people and is lost in addition, and a kind of 2 locking type Anti-theft cover for sewage well adopt fixedly teeth to stir ratch and just the technology of well lid pinning can be reported so far.
The utility model purpose is a kind of 2 the locking type Anti-theft cover for sewage well to go up shortcoming and provide in order to overcome.
This reality is novel to be achieved in that
It is that a retainer plate 7 is installed at existing well lid 2 backs, put a rotating Knucle-gear 4 again in the retainer plate centre, gear contacts with two ratch 3, after well lid being placed in above the well seat 6, be inserted into the hexagonal hole 5 interior and rotations of well lid 2 with six side's spanners, gear 4 is clockwise rotated, thus because of gear and ratch be interlocked make two rooted tooth bars to well seat direction extend and the platform of fill-in well seat along bottom, make well lid and well seat be fixed on one; Open well lid as need, then be rotated counterclockwise hexagonal hole, make the gear counter-rotating, ratch is return the original place, and well lid can take out.Thereby the task that realization the utility model proposes.
The utility model has the advantages that: be used for having installed fixedly ratch, gear additional at the well seat back side, only need handsetting gear during use, thereby ratch just can reach in the reinforcing rib well seat stand make along the below well lid and well seat each other one play the locking effect, overcome traditional well lid and well seat method fixedly the time, in addition, the utility model is because simple in structure, easily manufactured, can on existing manhole base, transform a little during use and just can use, thereby, can extensively promote the use of in municipal sewage well communication well head and other adit opening, ground well lid locking.
The utility model is provided by following examples:
Illustrated below in conjunction with accompanying drawing:
Accompanying drawing: 2 locking type Anti-theft cover for sewage well structural representations
The utility model is made up of reinforcing rib 1, well lid 2, ratch 3, gear 4, hexagonal hole 5, retainer plate 7.
It is to fix a retainer plate 7 at the back of well lid 2 with trip bolt 8, be carved with two road elongated slots on the retainer plate, respectively be placed with a ratch 3 in the elongated slot, have above the ratch this ratch of teeth of certain-length can be in elongated slot move left and right, be drilled with two circular holes in addition in the centre of retainer plate, wherein small sircle hole 5 is shaped as between hexagon and the well lid to connecting circular hole, and the major diameter circular hole is the step circular hole, big hole the inside is by putting a gear 4, and this gear and the teeth above the ratch can be together engaged; Gear center hole is that the hexagon circular hole of hexagonal hole and retainer plate top connects, firmly flexible in the elongated slot position in order to make about ratch, the spy has set up two road reinforcing ribs 1, reinforcing rib is the hollow strip, ratch is at interior retractable, two road reinforcing ribs are distributed in around the retainer plate in addition, vertical each other with above-mentioned twice reinforcing rib, different is that reinforcing rib is the entity shape.
When well lid is put into well seat 6 above after, be inserted into six side's spanners in six side's small sircle holes 5 of well lid 2, gear 4 up times are rotated, because of gear and ratch are interlocked, thereby two rooted tooth bars are extended to well seat stand rank 6 directions, and be inserted into the bottom of well seat stand along 6, well seat, well lid are fixed on simultaneously, open well lid as need, then be rotated counterclockwise six side's apertures, make the gear counter-rotating, ratch is return the original place, well lid can take out, thus the task that realization the utility model proposes.
The employed material of the utility model is a cast iron; Or plumbous material, reinforcing rib 8 can not established yet.
