Detailed description of the invention
For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As Figure 1-4, the concealed anti-stealing manhole cover of a kind of lockset of the present embodiment, the well lid 2 comprising well seat 1 and be located in well seat 1, well lid 2 is double-decker, comprise upper cover plate 3 and lower cover 4, be provided with connection strengthening rib 5 between upper cover plate 3 and lower cover 4, on the left of well lid 2, be provided with vertical strip through-hole 6, in the well lid 2 on the left of strip through-hole 6, be provided with retaining mechanism; Retaining mechanism comprise into U-shaped connect 2 dead bolts, be located at the well seat sidewall lockhole corresponding with dead bolt, upper cover plate bottom surface is provided with 2 parallel fixed sleevings 9, back-moving spring is provided with in fixed sleeving 9, dead bolt 7 is provided with spring retainer block through the position after back-moving spring, between back-moving spring is located on the right side of spring retainer block and fixed sleeving 9, fix with fixed sleeving 9 inwall on the right side of it.
As shown in Figure 5, the supporting opener that the present embodiment provides, comprise montant 11, hook part 12 perpendicular to montant 11 is installed in lower end, the end bending of hook part 12 upwards, unlatching to U-shaped dead bolt and lockhole when rotating montant 11 to coordinate, through hole 6 length of bar shaped is greater than the length of hook part 12, its width can be a bit larger tham the diameter of montant 11, in addition, the horizontal length of hook part 12 should between the distance in the U-shaped portion center of circle when heart pins to retaining mechanism or opens in through-holes, to have facilitated the quick-fit of hook part 12 and dead bolt.The top of montant 11 arranges handle 13, when facilitating well seat 1 and well lid 2 to open, to the gripping of montant 11, and when both open, can upwards mention well lid 2 by handle 13 and hook part 12.
Specifically, the well lid 2 of the present embodiment is the double-decker of circle, and hinged with well seat 1 on the right side of it, when promoting well lid, the left side of well lid is driven by montant 11 to be moved, and rotates around jointed shaft, and what make well lid 2 opens and move safer stablizing.Well lid 2 is made up of upper cover plate 3 and lower cover 4, and the area of lower cover 4 is less than the area of upper cover plate 3, can avoid the problem of the compacted and very difficult unlatching of well lid 1.In order to improve the structural strength of well lid 2, the crisscross reinforcing rib of multiple tracks 5 being set between upper cover plate 3 and lower cover 4, relative to existing well lid, can reducing by the weight of more than 20%, save material, decrease manufacturing cost preferably.The left side of well lid 2 is provided with through hole 6, retaining mechanism is arranged between upper cover plate 3 on the left of through hole 6 and lower cover 4, by fixed sleeving 9, the dead bolt that 2 become U-shaped to connect is arranged on the bottom surface of upper cover plate 3, after can avoiding long-time use, fixed sleeving 9 is easily by rain erosion, and then affect the performance of dead bolt 7, to improve the stability of locking.
The right side of dead bolt 7 is provided with limiting plate 10, and limiting plate 10 has the effect of two aspects, and one is the stroke that can limit dead bolt 7 movement to the right, avoids its landing from fixed sleeving 9; Two is retaining mechanism to be set to concealed, avoids artificial destruction, improves its theftproof performance.Further, intake in fixed sleeving 9, affect its performance, sealing ring can also be set at the two ends of fixed sleeving 9.
During use, supporting opener of the present utility model is inserted from strip through-hole 6, rotate the dead bolt 7 that hook part 12 is aimed at U-shaped by montant 11, pull-up montant 11 thus end hook part 12 upwards bent and dead bolt 7 complete overlap joint, rotating montant 11 can drive dead bolt 7 to depart from from lockhole 8, thus opens, the retaining mechanism between well lid 2 and well seat 1 then by handle 13 carries well lid 2, namely can complete opening of electric power well, facilitate the maintenance of the equipment such as electric power.
Compare with existing anti-stealing manhole cover, retaining mechanism in the present embodiment is concealed setting, there is no conventional key and engagement mechanism, lockhole can not be produced buried dead by native stone etc. and cause the problem that well lid cannot be opened, or produce the corrosion of key operated place after long-time use, and then increase the cost safeguarding use, the defect shortening its application life.Meanwhile, this well lid adopts lockset concealed, and add the difficulty that it is opened by general tool, non-supporting opener of the present utility model is difficult to open, and can avoid the deficiency of existing anti-stealing manhole cover, possess anti-theft function just, opens convenient, application life.
The technology contents of the not detailed description of the utility model is known technology.
