Abstract

The utility model provides a lockable anti-theft tubular well cover which comprises a base, a cover plate and a locking bolt. The lockable anti-theft tubular well cover is characterized in that a tubular well head is formed in the center of the base, a base locking screw hole is formed in an appropriate position of the base in a radius direction, base lock catches are arranged between the base locking screw hole in the base in a radius direction and the tubular well head, handles and exhaust vents are symmetrically arranged in the appropriate positions of the cover plate in a radius direction, a cover plate locking hole is formed in the cover plate in a radius direction, cover plate lock catches are arranged in the positions of the inner surface of the cover plate in a radius direction, and the cover plate lock catches and the base lock catches can be connected together by rotating the cover plate. The tubular well cover can be completely locked, and accidents caused due to the fact that water in a tubular well or on the ground rushes to the tubular well cover are avoided.

Description

But a kind of anti-theft pipe well lid of locking

Technical field

But the present invention relates to a kind of anti-theft pipe well lid of locking, by the interlocking of base snap close and cover plate snap close, can be fully locked, avoid in pipe well or the water on ground is washed the pipe well lid open and security incident occurs.

Background technology

Existing municipal pipe well lid is the quality compression pipe well mouth by well lid self, heavy, transportation inconvenience, although under normal circumstances, the pipe well lid generally can not be shifted, when vehicle spreading or large water slug are arranged, the possibility that displacement occurs the pipe well lid is just very large, several years ago in order to reduce the phenomenon of stealing the pipe well lid, the material that pipe well is covered is replaced with engineering plastics by cast iron in China, but the problem that may be shifted to the pipe well lid does not thoroughly solve.

because there are all deficiencies in urban drainage pipe network, in case run into rainstorm weather, urban sewerage and drainage all may go wrong, a large amount of rainwater may be collected in the part, the possibility washed open of pipe well cover is very large in this case, in case excess surface water, be easy to have an accident, when in July, 2012, Beijing suddenly rained cats and dogs, just occured a lot of because the casualty accident of pipe well lid displacement, when in March, 2013, Changsha suddenly rained cats and dogs, the accident that a pedestrian falls into pipe well just occurs in the Changsha Tianxin District, therefore, fundamentally solve because hydraulic blow causes the problem of pipe well lid displacement significant.

Summary of the invention

The problem of displacement occurs for rainwater impact tube well lid, but the invention provides a kind of anti-theft pipe well lid of locking.

the technical scheme that addresses the above problem is: but a kind of anti-theft pipe well lid of locking, comprise base (1), cover plate (2) and locking bolt (3), it is characterized in that: base (1) center arranges pipe well mouth (9), on base (1) radial direction, base locking screw (7) is established in the appropriate location, establish base snap close (5) between the base locking screw (7) of base (1) radial direction and pipe well mouth (9), on cover plate (2) radial direction, the appropriate location is symmetrical arranged handle (8) and steam vent (10), on cover plate (2) radial direction, cover plate locking hole (4) is set, the suitable radial location of cover plate (2) inner surface arranges cover plate snap close (6), together with rotation cover (2) can make cover plate snap close (6) and base snap close (5) is locked at.

Beneficial effect of the present invention: by the interlocking of base snap close and cover plate snap close, can be complete locked pipe well lid is avoided in pipe well or the water on ground is washed the pipe well lid open and security incident occurs.

The specific embodiment

By reference to the accompanying drawings but the anti-theft pipe well lid of a kind of locking of the present invention is done step explanation:

but a kind of anti-theft pipe well lid of locking, comprise base (1), cover plate (2) and locking bolt (3), it is characterized in that: base (1) center arranges pipe well mouth (9), on base (1) radial direction, base locking screw (7) is established in the appropriate location, establish base snap close (5) between the base locking screw (7) of base (1) radial direction and pipe well mouth (9), on cover plate (2) radial direction, the appropriate location is symmetrical arranged handle (8) and steam vent (10), on cover plate (2) radial direction, cover plate locking hole (4) is set, the suitable radial location of cover plate (2) inner surface arranges cover plate snap close (6), together with rotation cover (2) can make cover plate snap close (6) and base snap close (5) is locked at.

Described locking screw (7) is internal thread hole.

Described locking bolt (3) screw rod is external screw thread, and external thread length is identical with locking screw (7) thickness, and the nut of locking bolt (3) is hexagonal socket nut.

Described base snap close (5) is evenly distributed on the annulus of the upper suitable radius of base (1), and base snap close (5) both sides wire clamp angle b is not more than 60 °.

Described cover plate snap close (6) is evenly distributed on the annulus of the upper suitable radius of cover plate (2), and cover plate snap close (6) both sides wire clamp angle a is not more than 60 °.

The axis of the axis of the base locking screw (7) of described base (1) and the cover plate locking hole (4) of cover plate (2) overlaps when locked base snap close (5) and cover plate snap close (6) are complete.

Described base snap close (5) and cover plate snap close (6) are complete when locked, and locking bolt (3) is arranged on locking screw (7).
