Abstract
The utility model discloses a kind of oil tank hatchcover opening and closing device, comprise handwheel, sleeve, location-plate, back shaft and helical axis, described helical axis lower surface is provided with screw, screw is furnished with bolt, helical axis bottom is arranged with thread bush, between thread bush and bolt, be provided with pad, pad external diameter is greater than the internal diameter of thread bush.The utility model has thread bush at helical axis lower end cover, is fixed, solve the technical problem that sleeve has the risk taken off by bolt and pad, and structure design is simple, very practical; The setting of thread bush, makes back shaft uniform force, adds stability, decreases the loss of back shaft simultaneously, reduces maintenance cost, adds the application life of product.
Description
Technical field
The utility model relates to a kind of rotary type oil tank hatchcover, the opening and closing device specifically on a kind of oil tank hatchcover, the helical axis more particularly on opening and closing device.
Background technology
As shown in Figure 1, in prior art, the helical axis lower end of oil tank hatchcover opening and closing device does not have bolt, if rotation hand wheel always, last sleeve has the risk taken off, this sleeve supports whole oil tank hatchcover lid, and this takes off danger close! Sleeve will drive lid, and it is very uneven for accepting.
Notification number CN 201794426 U discloses a kind of oil tank hatchcover opening and closing lifting gear, and disclose screw axis (being equivalent to the helical axis in the application) in literary composition, if this screw axis rotates always, last sleeve has the risk taken off.For addressing the aforementioned drawbacks, now provide a solution.
Utility model content
The purpose of this utility model is to provide a kind of oil tank hatchcover opening and closing device.
The purpose of this utility model can be achieved through the following technical solutions:
Oil tank hatchcover opening and closing device, comprises handwheel, sleeve, location-plate, back shaft and helical axis, and described helical axis lower surface is provided with screw, screw is furnished with bolt, helical axis bottom is arranged with thread bush, between thread bush and bolt, be provided with pad, and pad external diameter is greater than the internal diameter of thread bush.
The beneficial effects of the utility model: the utility model has thread bush at helical axis lower end cover, is fixed, solve the technical problem that sleeve has the risk taken off by bolt and pad, and structure design is simple, very practical; The setting of thread bush, makes back shaft uniform force, adds stability, decreases the loss of back shaft simultaneously, reduces maintenance cost, adds the application life of product.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is oil tank hatchcover opening and closing device elevation in prior art.
Fig. 2 is the utility model oil tank hatchcover opening and closing device elevation.
Fig. 3 is helical axis elevation.
Fig. 4 is oil tank hatchcover elevation.
Detailed description of the invention
Oil tank hatchcover opening and closing device, comprise handwheel 1, sleeve 3, location-plate 4, back shaft 6 and helical axis 2, as shown in Figure 4, location-plate 4 one end is weldingly fixed on the guide strip of coaming plate, base plate 5 is fixed on the bearing of coaming plate, as Fig. 2, back shaft 6 lower end is fixed on base plate 5, and sleeve 3 lower end is through location-plate 4, inside, sleeve 3 lower end is provided with lining 8, lining 8 is fixed on sleeve 3 by interior hexagonal holding screw 7 without a head, and back shaft 6 top is positioned at sleeve 3, and lining 8 is between back shaft 6 and sleeve 3.Back shaft 6 upper end is fixed with nut 16 by flush end holding screw 15, and helical axis 2 through nut 16, and is inserted in back shaft 6, and the material that helical axis 2 adopts is stainless steel, nut 16 be copper material, there is good anti-wear performance.Helical axis 2 upper end is provided with handwheel 1, and its top is also by single direction thrust ball bearing 14 with axle sleeve 10 is rotating is located at sleeve 3 upper end, and sleeve 3 upper end is also provided with plug 9.As Fig. 3, helical axis 2 lower surface is provided with screw 17, and screw 17 is furnished with bolt 12, and bolt 12 can be M14X40 bolt.Helical axis 2 bottom is arranged with thread bush 11, and thread bush 11 supports fixing by the bolt 12 screwing in helical axis 2 lower end, and between thread bush 11 and bolt 12, be also provided with pad 13, pad 13 external diameter is greater than the internal diameter of thread bush 11.
As Fig. 1, if people's rotation hand wheel 1 always, last sleeve 3 has the risk taken off, and this sleeve 3 supports whole oil tank hatchcover lid, and this takes off danger close.In order to prevent people's rotation hand wheel 1 always, the utility model has thread bush 11 at helical axis 2 lower end cover, is fixed by bolt 12 and pad 13.Solve the technical problem that sleeve 3 has the risk taken off, structure design is simple, very practical.
Meanwhile, because the wall built-up 18 on sleeve 3 connects oil tank hatchcover, time oil tank hatchcover rises, because the problem of center of gravity, oil tank hatchcover has the weight of side, under the Action of Gravity Field of side, back shaft 6 discontinuity, back shaft 6 can be made to contact with helical axis 2.After the utility model improves, back shaft 6 coordinates with thread bush 11, the setting of thread bush 11, makes back shaft 6 uniform force, adds stability, decrease the loss of back shaft 6 simultaneously, reduce maintenance cost, add the application life of product.
Above content is only to the utility model structure example and explanation; affiliated those skilled in the art make various amendment to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the structure of utility model or surmount this scope as defined in the claims, protection domain of the present utility model all should be belonged to.
