Description
Technical field
This utility model is related to town road infrastructure construction field, and more particularly, to one kind is opened by spring assistor
The well lid opening.
Background technology
Large scale well lid is heavier due to conducting oneself with dignity, generally more than 100 kilograms, opens very difficult inside well head.And be used for
The escaping exit well lid of pipe gallery is it is necessary to from internal quick unlatching, for solving this problem, develop following spring assist well
Lid.
Content of the invention
A kind of well opened by spring assistor providing for the drawbacks described above of prior art, this utility model
Lid, it is heavier due to conducting oneself with dignity to solve large scale well lid, opens very difficult problem inside the well head.
In order to achieve the above object, this utility model provides following technical scheme：
A kind of included by the well lid that spring assistor is opened：Removable cover, firm banking, spring assembly, support arm, L
Shape pull bar, hinge, described removable cover is connected with firm banking by hinge, draws further through stud connection support arm and L-shaped simultaneously
Bar, described spring assembly is linked with L-shaped pull bar and is connected with firm banking by hinge.
The beneficial effects of the utility model are：A kind of well opened by spring assistor that this utility model provides
Lid, with spring tension balance well lid deadweight, it is possible to achieve realize the unlatching of well lid, closing it is possible to pass through with the thrust of very little
Locking device it is allowed to well lid opening and closing either internally or externally, to ensure the requirement of the needs and safe anti-intrusion escaped.
In order to be able to be further understood that feature of the present utility model and technology contents, refer to new below in connection with this practicality
The detailed description of type and accompanying drawing, but accompanying drawing only provides and uses with reference to explanation, is not used for this utility model is any limitation as.
Brief description
Below in conjunction with the accompanying drawings, by describing in detail to specific embodiment of the present utility model, will make of the present utility model
Technical scheme and other beneficial effects are apparent.
Fig. 1 is a kind of structural representation of the well lid opened by spring assistor of this utility model.
Fig. 2 is a kind of structural representation of the well lid opened by spring assistor of this utility model.
Specific embodiment
For further illustrating the technological means and its effect that this utility model taken, below in conjunction with of the present utility model
Preferred embodiment and its accompanying drawing are described in detail. 2
Refer to Fig. 1, a kind of included by the well lid that spring assistor is opened：Removable cover 1, firm banking 2, spring
Device 3, support arm 4, L-shaped pull bar 5, hinge 6, described removable cover is connected with firm banking by hinge, simultaneously further through hinge
Connecting support arm and L-shaped pull bar, described spring assembly is linked with L-shaped pull bar and is connected with firm banking by hinge.
Removable cover 1 in off position when spring assembly 3 L-shaped pull bar 5 is rotated by hinge 6 be tightened up and be in pretension shape
State, when removable cover 1 needs to open, staff need to open safety lock and elect upwards.Spring assembly 3 shrinks and drives L-shaped
Pull bar 5 balance well lid deadweight, so as to rotating around hinge 6 and allowing support arm 4 promote removable cover 1, just can power-assisted be dug.Work as activity
Cover plate 1 is translated into and is completed self-locking during range.
Removable cover 1 closing process with aforementioned contrary, conducted oneself with dignity substantially by spring tension with well lid by the downward gravity of removable cover 1
Balance.Need staff closing assisted.Hinge 6 rotates and drives support arm 4 downwards, is associated with the L-shaped pull bar 5 linking around hinge
Axle 6 moves to backswing, pulls the gravity of spring assembly 3 balancing activity cover plate 1, and staff pushes down on by during to well lid closure state
Locked by locking device.
The above, specific embodiment only of the present utility model, but protection domain of the present utility model does not limit to
In this, any those familiar with the art, in the technical scope that this utility model discloses, can readily occur in change
Or replace, all should cover within protection domain of the present utility model.Therefore, protection domain of the present utility model should described to weigh
The protection domain that profit requires is defined.
