Description
Technical field
The invention belongs to ship equipment technical fields, are related to a kind of safety manhole lid.
Background technique
The cover board of existing manhole cover is generally cast iron flat, because cast iron flat itself is than heavier, and staff exists
There is no safeguard procedures when being opened and closed, once the landing so cover board is accidentally dropped, easily causes personal injury to operator, therefore have
Necessity improves.
Summary of the invention
The purpose of the present invention is be directed to the above-mentioned problems in the prior art, provide it is a kind of can cover board open situation
Lower offer support avoids that unexpected safety manhole lid occurs.
Object of the invention can be realized by the following technical scheme: a kind of safety manhole lid, including by being parallel to each other
Front panel and squab panel, and the left coaming plate and right coaming plate that are parallel to each other surround the square tube shape manhole to be formed, be stamped on manhole with
The squab panel cover board hinged by hinged shaft, it is characterised in that: further include support frame, support frame includes two framves being parallel to each other
Bar, and with two hack lever one end support rods connected vertically, set respectively on the side that the left coaming plate is mutually stood erect with right coaming plate
There is the gap slot that shape is identical and slot bottom is triangular in shape, two hack lever other ends pass through pin shaft respectively and are hinged on two gap slots
On, and pin shaft is parallel with support rod, and vertical with left coaming plate and right coaming plate, and two pin shafts are set between two gap slots respectively
There is torsional spring, further includes the spring catch for being fixed on support rod one end, the left coaming plate is equipped with jack, and torsional spring can drive support
Frame is overturn around pin shaft, and is against two hack levers respectively on two gap slot side cell walls, at this time the high Access Opening of support rod
Top, and be supported on cover board bottom surface, hack lever and cover board bottom surface angle are greater than 90 ° at this time, pin shaft overturning support can be also surrounded,
Make support rod constantly close to front panel, and reduce hack lever constantly with cover board bottom surface angle, and by pulling spring catch to make spring
Pin end is inserted in jack and fixing support rack.
After cover board is opened, torsional spring can drive support frame to overturn around pin shaft, be against two hack levers respectively and lack at two
On the cell wall of mouth slot side, at this time at the top of the high Access Opening of support rod, therefore even if cover board accidentally turns over down, it can also be supported on support rod
On, hack lever and cover board bottom surface angle are greater than 90 ° at this time, so that support is more stable, and can use support rod conduct and help
Hand lever access manhole uses, and when needing lid closing lid plate, surrounds pin shaft overturning support, and by pulling spring catch to make spring catch end
Portion is inserted in jack and fixing support rack, thus can convenient cap closing lid plate, and cover close after manhole will not be had an impact.
In a kind of above-mentioned safety manhole lid, when the support frame is by spring catch and fixed jack cooperation, institute
The support rod stated is bonded with front panel.
Therefore structure is more compact, avoids having an impact manhole inside after lid closes.
In a kind of above-mentioned safety manhole lid, the support rod other end also is provided with spring catch, and sets in right coaming plate
There is the jack with the cooperation of the spring catch of the support rod other end.
Therefore connection is more stable.
In a kind of above-mentioned safety manhole lid, activity is cased with sheath on the support rod, and sheath can be around support
Rod axis rotation.
Therefore facilitate and used as handrail.
Compared with prior art, the present invention has the advantage that
After cover board is opened, torsional spring can drive support frame to overturn around pin shaft, be against two hack levers respectively and lack at two
On the cell wall of mouth slot side, at this time at the top of the high Access Opening of support rod, therefore even if cover board accidentally turns over down, it can also be supported on support rod
On, hack lever and cover board bottom surface angle are greater than 90 ° at this time, so that support is more stable, and can use support rod conduct and help
Hand lever access manhole uses, and when needing lid closing lid plate, surrounds pin shaft overturning support, and by pulling spring catch to make spring catch end
Portion is inserted in jack and fixing support rack, thus can convenient cap closing lid plate, and cover close after manhole will not be had an impact.

Specific embodiment
Following is a specific embodiment of the present invention in conjunction with the accompanying drawings, technical scheme of the present invention will be further described,
However, the present invention is not limited to these examples.
As depicted in figs. 1 and 2, a kind of safety manhole lid of the present invention, including the front panel 11 and squab panel by being parallel to each other
12, and the left coaming plate 13 and right coaming plate 14 that are parallel to each other surround the square tube shape manhole 1 to be formed, it is stamped on manhole 1 and squab panel
12 by the hinged cover boards 2 of hinged shaft, further include support frame, and support frame includes two hack levers being parallel to each other 3, and with two framves
3 one end of bar support rod 31 connected vertically, is respectively equipped with that shape is identical and slot on the side that left coaming plate 13 is mutually stood erect with right coaming plate 14
Bottom gap slot 15 triangular in shape, two 3 other ends of hack lever pass through pin shaft 32 respectively and are hinged on two gap slots 15, and pin shaft
32 is parallel with support rod 31, and vertical with left coaming plate 13 and right coaming plate 14, and two pin shafts 32 respectively with two gap slots 15 it
Between be equipped with torsional spring, further include the spring catch 33 for being fixed on 31 one end of support rod, left coaming plate 13 is equipped with jack 16, and torsional spring energy band
Dynamic support frame is overturn around pin shaft 32, and is against two hack levers 3 respectively on two 15 side cell walls of gap slot, is supported at this time
High 1 top of Access Opening of bar 31, and be supported on 2 bottom surface of cover board, hack lever 3 and 2 bottom surface angle of cover board are greater than 90 ° at this time, can also enclose
Around 32 overturning support of pin shaft, make support rod 31 constantly close to front panel 11, and subtracts hack lever 3 constantly with 2 bottom surface angle of cover board
It is small, and by pulling spring catch 33 that 33 end of spring catch is made to be inserted in jack 16 simultaneously fixing support rack.
Further, when support frame is by spring catch 33 and the fixed cooperation of jack 16, support rod 31 and front panel 11 are pasted
