Description

A kind of anti-stealing manhole cover of 180 ° of unlatchings of energy

Technical field

This utility model is related to a kind of road equipment technical field, specifically a kind of anti-stealing manhole cover of 180 ° of unlatchings of energy.

Background technology

Well lid, for covering road or family's middle-deep well, prevents people or object from falling, and the inconvenience management due to well lid adds again Upper part lawless person personnel, under the ordering about of interests, often result in the loss of well lid, and the loss of well lid not only causes public setting The destruction applied and easily pedestrian is damaged.Traditional anti-stealing manhole cover be connected by single screw connection hinge, hinge Chain is often exposed to outside, and antitheft and security performance is low and in use, the rotation of screw and vibrations can cause road surface Go wrong, well lid opening angle in opening process can be caused limited using screw connection hinge, due to be limited to screw with The connected mode well lid of hinge can not completely lie low on road surface, and the weight of itself can be to hinge in opening for such well lid Chain and screw produce shear pressure, thus reducing the service life of well lid；Need destruction road surface will also result in when changing well lid Unnecessary trouble.

Utility model content

The purpose of this utility model is to provide a kind of anti-stealing manhole cover of 180 ° of unlatchings of energy, to solve in above-mentioned background technology The problem proposing.

For achieving the above object, this utility model provides following technical scheme：

A kind of anti-stealing manhole cover of 180 ° of unlatchings of energy, including walling crib, well lid, hinge, slide rail, pin hole, spring arm and slide rail Groove；Described slide rail is fixedly mounted on the inner side of well lid, is provided with sliding rail groove in slide rail；Described hinge one end is hinged to well Circle, the other end connects to the sliding rail groove of slide rail, and hinge is slidably connected with slide rail；Described rail tips are provided with pin hole, Latch in the hole is provided with latch.

As further program of the utility model：Described spring arm is arranged on the inner side of well lid, and spring arm is provided with altogether Three.

As this utility model further scheme：It is provided with anti-slip veins outside described well lid.

Compared with prior art, the beneficial effects of the utility model are：

Hinge is arranged on inside well lid the anti-stealing manhole cover of 180 ° of unlatchings of instinct, in the invisible hinge in outside, and passes through Latch is locked, that is, enhance anti-theft and increased attractive in appearance again, and be capable of 180 ° of well lid by the cooperation of hinge and slide rail Unlatching.Well lid can be made in open manhole cover to lie low and to avoid the shearing force to hinge for the well lid self gravitation on road surface, thus Increased the service life of well lid, when in addition changing well lid, do not need destruction road surface to increased convenience.

Specific embodiment

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of making creative work The every other embodiment being obtained, broadly falls into the scope of this utility model protection.

Refer to Fig. 1～6, in this utility model embodiment, a kind of anti-stealing manhole cover of 180 ° of unlatchings of energy, including walling crib 1, well Lid 2, hinge 3, slide rail 4, pin hole 5, spring arm 7 and sliding rail groove 6；Described spring arm 7 is arranged on the inner side of well lid 2, spring Arm 7 is provided with three altogether, after well lid 2 covers, spring arm 7 be stuck in well seat interior along upper, be used for fixing well lid 1；Described cunning Rail 4 is fixedly mounted on the inner side of well lid 2, is provided with sliding rail groove 6 in slide rail 4；Described hinge 3 one end is hinged to walling crib 1, another End connects to the sliding rail groove 6 of slide rail 4, and hinge 3 is slidably connected with slide rail 4；Described slide rail 4 top is provided with pin hole 5, inserts It is provided with latch, pin hole 5 is used for locked hinge 3 with the cooperation of latch in pin-and-hole 5, thus locked well lid 2；Outside described well lid 1 Side is provided with anti-slip veins.

Operation principle of the present utility model is：

One end fixation of hinge 3 is hinged in walling crib 1, and walling crib 1 is fixedly mounted on road surface, then that hinge is another End connects to the sliding rail groove 6 of slide rail 4, inserts latch by the pin hole 5 of slide rail 4 upper end thus locked hinge, Jin Ersuo Dried-up well lid 2；Hinge 3 can enter line slip along slide rail 4.

Hinge is arranged on inside well lid by the anti-stealing manhole cover of 180 ° of unlatchings of instinct, that is, enhance anti-theft and increased U.S. again See, and be capable of the unlatching of 180 ° of well lid by the cooperation of hinge and slide rail.Well lid can be made to lie low in open manhole cover Avoid the shearing force to hinge for the well lid self gravitation on road surface, thus increased the service life of well lid.

It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and And in the case of without departing substantially from spirit or essential attributes of the present utility model, this practicality can be realized in other specific forms new Type.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, this practicality is new The scope of type is limited by claims rather than described above, it is intended that the containing of equivalency that will fall in claim All changes in justice and scope are included in this utility model.Any reference in claim should not be considered as limiting Involved claim.
