Description
Technical field
The utility model relates to a kind of well lid, is specifically related to a kind of anti-stealing manhole cover.
Background technology
In urban construction, because bury and safeguard the needs of underground pipeline underground in the future, under the road surface, need to arrange blow-off line well, gas pipeline well and electric power, communication cable operation well etc., the well lid that arranges at the well head of these wells is mostly by the cast iron manufacturing, because anti-theft effect is poor, usually stolen by the unprincipled fellow, seriously jeopardize contact vehicle and pedestrian's the security of the lives and property, become a big hidden danger in city.For addressing the above problem, occurred some anti-stealing manhole covers in recent years, but majority or anti-theft effect are not good enough or complex structure or difficult the unlatching yet.
The utility model content
The purpose of this utility model is to provide a kind of anti-stealing manhole cover, is intended to solve problems such as complex structure, poor, the difficult unlatching of anti-theft effect.
The technical solution of the utility model is such:
Anti-stealing manhole cover comprises wellhead receptacle and the well lid that is positioned on the wellhead receptacle, and described well lid dorsal edge is provided with first clamp, and wellhead receptacle is provided with first draw-in groove of described first clamp of plug-in mounting; Become position, 180 ° of angles to be provided with a protruding block in described well lid dorsal edge with described first clamp, described protruding block is provided with a through hole, and described wellhead receptacle is being provided with second draw-in groove with described through hole corresponding position; Also be provided with an opening on the described well lid;
Be provided with a spring in the described through hole, this spring one end is fixed in the described through hole, and the other end is connected with second clamp; The described well lid back side is connected with a swingle by bearing, and described swingle and described opening are on same longitudinal axis; Be connected with chain between described swingle and described second clamp.
The beneficial effects of the utility model have: 1, in whole opening process, artificial needs two steps: use opener rotation swingle and mention well lid, unlatching work is simple and convenient; 2, open well lid and need special-purpose opener, good anti-theft effect; 3, this anti-stealing manhole cover has only increased a few parts such as spring, clamp, bearing, swingle, so overall structure is simple, and cost and maintenance cost are low; In sum, this uses novel easy and simple to handle, good anti-theft effect, simple in structure.
Description of drawings
Fig. 1 is structure chart of the present utility model;
Fig. 2 is vertical view of the present utility model;
Fig. 3 is the structure chart of opener.
The specific embodiment
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
With reference to figure 1,2,3, a kind of anti-stealing manhole cover comprises wellhead receptacle 1 and the well lid 2 that is positioned on the wellhead receptacle 1; Described well lid 2 dorsal edge are provided with first clamp 4, and wellhead receptacle 1 is provided with first draw-in groove 3 of described first clamp 4 of plug-in mounting; Be provided with a protruding block 5 in described well lid 2 dorsal edge with position, 4 one-tenth 180 ° of angles of described first clamp, described protruding block 5 is provided with a through hole (not shown), and described wellhead receptacle 1 is being provided with second draw-in groove 6 with described through hole corresponding position; Also be provided with an opening 7 on the described well lid 2;
Be provided with a spring 8 in the described through hole, these spring 8 one ends are fixed in the described through hole, and the other end is connected with second clamp 9; Described well lid 1 back side is connected with a swingle 12 by bearing 11, and described swingle 12 and described opening 7 are on same longitudinal axis; Be connected with chain 10 between described swingle 12 and described second clamp 9.
The concrete connected mode of its middle (center) bearing 11 and swingle 12 can for: described swingle 12 upper ends are passed described bearing 11 and are positioned on the described bearing 11, and the inwall of described bearing 11 is fixedlyed connected with the outer wall of swingle 12.
Optimize, described opening 7 is provided with a seal cover (not shown), prevents that opening 7 from being stopped up by foreign matter.
Optimize, described second clamp 9 to be shaped as chamfer trapezoidal, the italicized item of described right-angled trapezium is used for inserting second draw-in groove 6, when closing well lid 1, with well lid 1 past pressing down, promoting described second clamp 9 behind the inclined-plane pressurized of described second clamp 9 shrinks in through hole, after described second clamp 9 is contracted to through hole fully, well lid 1 falls to both allocations, afterwards, second clamp 9 is ejected and snaps in second draw-in groove 6 by described spring 8, and this prioritization scheme is simplified and closed the operation of well lid, effectively promotes operating efficiency.
During concrete enforcement, described chain 10, bearing 11, swingle 12, spring 8, second clamp 9 are made by stainless steel, prevent from that above-mentioned parts are exposed to for a long time corrosion takes place in the wet environment, effectively prolong the application life of well lid 1.
In addition, for optimizing structure, described opening 7 be shaped as circle, can certainly be other geometric figure shapes.
With reference to figure 3, with described well lid 2 matching used openers 20, comprise stock 21 and the insert 22 that is positioned at stock 21 lower ends, described insert 22 bottoms have groove 23, the shape of described insert 22 and described opening 7 shapes are complementary, so the shape of the shape of groove 23 and described swingle 12 upper ends is complementary; Be that reply opens the intensity of well lid 2, described stock 21 and insert 22 are made by stainless steel, can certainly be made by other high-intensity materials.
The concrete opening process of whole anti-stealing manhole cover is as follows, and behind the insert 22 insertion openings 7 with opener 20, the groove 23 of insert 22 bottoms snaps in the upper end of swingle 12, then by rotating the rotation of opener 20 driven rotary bars 12; The rotation of swingle 12 is progressively tightened up chain 10, the chain 10 that progressively tightens up forces spring 8 compressions, the compression of spring 8 drives the indentation in the through holes of second clamp 9, and second clamp 9 is up carried well lid 2 after being fully retracted to the through hole, and the unlatching work of whole anti-stealing manhole cover is so far finished.
The above only is preferred embodiment of the present utility model, not in order to limiting the utility model, all any modifications of doing within spirit of the present utility model and principle, is equal to and replaces and improvement etc., all should wrap in the utility model scope.
