Specific embodiment
Embodiment 1
As shown, a kind of screw connected headstock gear of small-sized hatchcover, including cabin 7, small-sized hatchcover 2 are hinged on cabin 7,
U-shaped piece 5 is equipped on the small-sized hatchcover 2, described U-shaped piece 5 is equipped with nut locating ring 4, is also equipped with bayonet lock in U-shaped piece 5
17；
Pin hole seat 10 is installed, the pin hole seat 10 is equipped with pin hole 8, and pin shaft 11 is mounted in pin hole 8, institute on the cabin 7
It states and is welded with bolt 12 on pin shaft 11, the bolt 12 is equipped with the card slot 18 being stuck in bayonet lock 17, and locking nut 9 is mounted on spiral shell
On bolt 12, the two sides of the locking nut 9 are equipped with rotational handle 13；The surrounding in the cabin 7 is additionally provided with rhone 19, described
Rhone 19 is connect with vessel sewage pipe.
The bottom of small-sized hatchcover 2 is equipped with hatchcover sealing ring 1, and U-shaped piece 5 of two sides are separately installed with the first pull ring 3 and
Two pull rings 6.The end of the bolt 12 is additionally provided with cotter-pin hold 16, is equipped with split pin 14 in the cotter-pin hold 16.Cabin
Headlamp 22 is also equipped on the inside of room 7,22 side of headlamp is equipped with push switch 21.
Working principle of the present invention is as follows:
The connection in cabin and hatchcover: cabin 7 is hinge jointing type with hatchcover 2, and the two is linked together by positioning pin, hatchcover 2
The angular range that can be rotated around the positioning pin in cabin is 0 ° ~ 180 °.Hatchcover sealing ring 1 on hatchcover 2 is rubber material,
It is mainly used to seal hatch 7, while the surrounding in cabin 7 is additionally provided with rhone 19, when rainy, rainwater is along 19 row of rhone
Vessel sewage pipe is arrived out, is avoided the pollutants such as rainwater from entering cabin by above two mode, is caused dismantling device, measurer, object
The generations such as material and spare part are corroded and are scrapped.
Hatchcover locking: rotating 180 ° around 7 positioning pin of cabin for hatchcover 2, so that hatchcover 2 is just covered on cabin 7, this
When hatchcover 2 on sealing ring 1 abut against cabin 7, play preliminary sealing.
Pin hole seat 10 is welded on cabin 7, there is pin hole 8 in pin hole seat 10, for assembling pin shaft 11, pin shaft 11 and bolt 12
Welding together, bolt 12 is to be threadedly coupled with locking nut 9, symmetrical rotational handle 13 is welded on locking nut 9,
Two handles are rendered as 180 ° and are arranged symmetrically.
Bolt 12 on cabin 7 is mentioned, the U-shaped mouth being fitted into U-shaped piece 5 on hatchcover 2, clockwise operation rotation hand
Handle 13 plays final locking effect until locking nut 9 is tightly fitted on the nut locating ring 4 on U-shaped piece 5.Operation rotation
The dynamics of handle 13 cannot be too big, avoids the screw thread between bolt 12 and locking nut 9 from being crushed skidding, causes screw thread cannot
Locking.
Nut locating ring 4 is the design of counterbore circular groove type, and closer to U-shaped piece 5 of symmetrical line position, U-shaped piece 5 of thickness is got over
It is thin.Nut locating ring 4 plays self-positioning effect, it is ensured that when hatchcover 2 is locked, ensure that the locked position of bolt and nut begins
It is eventually vertical direction, ensure that screw bolt and nut interaction force remains as the axial location of screw bolt and nut, not will cause spiral shell
The abnormal conquassation of line.
It is worn when U-shaped piece or bolt 12 occurs plastic deformation and is elongated or 9 lower end surface of locking nut is worn
Reason, the threaded connection between bolt 12 and locking nut 9 can loosen, and cannot lock hatchcover well.It at this time can be further
Operation rotational handle 13 realizes the locking of hatchcover, keeps away so that locking nut 9 is tightly fitted on nut locating ring 4 clockwise
Exempt from rainwater to enter cabin and corrode the dismantling device in cabin, measurer, material or spare part etc..
The speed of above-mentioned locking process is slow, repeatedly opens and closes sometimes, at this time if locked using locking nut 9
It is tight and open, it is clear that can inefficiency, therefore, the present invention is also equipped with bayonet lock 17 in U-shaped piece 5, by will be on bolt 12
Card slot 18 be hooked in bayonet lock 17, hatchcover 7 can also be blocked into locking, need to open the cabin be only need press after by bolt 12 from
Bayonet lock 17 pulls open, and hatchcover 2 is made to lose constraint, can both open hatchcover 2.
Hatchcover is opened: when the equipment such as winch, warping winch and windlass on ship deck need Quick overhaul, can be beaten
Open the cabin lid 2, takes out required dismantling device, measurer, material or spare part etc..Operate rotational handle 13, bolt 12 counterclockwise at this time
Threaded connection between locking nut can unclamp, and until locking nut 9 can be withdrawn from U-shaped piece 5 of U-shaped mouth, lift cabin
Hatchcover is turned over 180 ° until against cabin wall surface by the first pull ring 3 and the second pull ring 6 on lid 2, and hatchcover is opened completely at this time
It opens, dismantling device required for taking out, measurer, material or spare part etc..
It is furnished with cotter-pin hold 16 on bolt 12, a pin rod in the split pin 14 on cotter-pin hold 16 is up curved
Song, another pin rod 16 are bent down, be can avoid locking nut 9 and are split away off from bolt 12, when removing tool at night, in order to
Prevent cabin 7 is pitch-dark from not seeing, therefore the present invention is also also equipped with headlamp 22 on the inside of cabin 7, when needing to open, control is pressed
21 opening and closing compress switch to control the opening and closing of headlamp 22.
In addition to the implementation, the present invention can also have other embodiments.It is all to use equivalent substitution or equivalent transformation shape
At technical solution, fall within the scope of protection required by the present invention.
