Abstract
The utility model discloses a kind of outer door of water tank manhole, it is characterized in that lower header flushes the outer door of the water tank manhole in off position, water tank manhole external door inside configuration has doorframe structure and external door revolute axes configuration, limited location turning arm below the doorframe structure, there are two ' L ' shape support turning arms and detachable rotary shaft fixed seat in the external door revolute axes configuration, ' L ' shape supports turning arm external door rotary shaft and outward swinging door in succession, and detachable rotary shaft fixed seat is arranged on external door revolute axes configuration bottom.The present invention has used the motion principle of parallelogram, and the requirement to space is small, can effectively protect people's air defense hole, is suitable as the use of water tank external door.
Description
Technical field
The present invention relates to water tank manhole external door field, particularly belongs to a kind of outer door of water tank manhole.
Background technology
Water tank manhole is the passage for entering water tank maintenance for maintainer, above general water tank manhole installation water tank and side
Face.Long-term use of water tank manhole is it is found that problems with often occurs in water tank manhole：First, water tank manhole is outdoor peace
Often there is dead problem of becoming rusty in dress, long-term use；Second, the water tank manhole of outdoor installation is frequently encountered external force destruction, cause to draw
Send out water tank manhole deformation；Third, outer door occupancy peripheral space is big, fourth, the exploitation of traditional water tank manhole later-stage secondary is expanded
Difficulty is big when opening up electric and pneumatic formula automatic opening and closing door.The present invention provides a kind of water tank manhole outer door regarding to the issue above.
The content of the invention
The present invention provides a kind of water tank manhole outer door, and the water tank manhole for solving to find in above-mentioned technical background makes for a long time
Use produced problem.
The outer door of a kind of water tank manhole, it is characterised in that lower header is neat in off position for the outer door of the water tank manhole
Flat, water tank manhole external door inside configuration has doorframe structure and external door revolute axes configuration, the doorframe structure lower section limited location rotation
Arm, there are two ' L ' shapes support turning arms and detachable rotary shaft fixed seat, the support of ' L ' shape in the external door revolute axes configuration
Turning arm external door rotary shaft and outward swinging door in succession, detachable rotary shaft fixed seat are arranged on external door revolute axes configuration bottom.
It is a plurality of that ' L ' shape supports turning arm to share, and a plurality of ' L ' shapes support turning arm afterbodys have rotary sleeve, revolve
There is bearing in pivoted housing.
Compared with the prior art, beneficial effects of the present invention are as follows：
By carrying out decision design combination to door outside water tank manhole, solve what long-term use of water tank manhole often occurred
Problems with：First, water tank manhole is outdoor installation, often there is dead problem of becoming rusty in long-term use；Second, the water of outdoor installation
Case manhole is frequently encountered external force destruction, causes to trigger water tank manhole deformation；Third, outer door occupancy peripheral space is big；Four
It is that difficulty is big when the exploitation of traditional water tank manhole later-stage secondary extends electric and pneumatic formula automatic opening and closing door.The present invention uses
The motion principle of parallelogram, the requirement to space is small, can effectively protect people's air defense hole, is suitable as the use of water tank external door.
Brief description of the drawings
Fig. 1 is the structural side view of the present invention；
Fig. 2 is that ' L ' shape supports turning arm.
