Description
Technical field
The utility model relates to a kind of manhole latching device.
Background technology
The manhole facility be applied at present, of a great variety, fashionable, provide conveniently for the modern times are edible, medicine company is industrial.Widely used is in such applications the maximum of genus quick opening manhole, but major part all adopts opening presser type and handle nut to carry out locking to be connected in these quick opening manholes used at present, pressing plate and handle nut contact surface are plane-type contact, existing clamping part is clamping lever nut and opening briquetting is plane contact, screw thread in armrest handle carries out the motion clamping of screw pair, in long-term switch uses, planar end and the relative corner angle thereof of opening briquetting can wear and tear, and because of the pressure change in tank body in using, as the pressure increases, the reaction thrust of manhole cover strengthens, depression bar is caused to be out of shape (depression bar and opening briquetting are weld togethers).When the reason of these two aspects makes to produce relative motion between handle nut and opening briquetting, very likely come off, exist along with in tank body pressure raise time, the Light deformation in tank body part place, have influence on pressing plate and nut, will skid and cause pressing plate obscission, finally cause safety misadventure.
Summary of the invention
The utility model is intended to the defect overcoming prior art, provides a kind of manhole latching device, ensures that the use of manhole is safer, more reliable, can also bear certain pressure simultaneously.
In order to solve the problems of the technologies described above, the utility model is achieved in that
A kind of manhole latching device, is characterized in that: it comprises manhole mounting ring, manhole plate, depression bar, clamping screw, opening briquetting, handle nut, connecting panel and three fixed mounts;
Manhole plate covers on manhole mounting ring top;
Three fixed mounts are U-board, and U-board is made up of with the transverse slat being connected two pieces of riser lower ends two pieces of risers be arranged in parallel, and riser all has hole;
Side lateral connection first fixed mount of manhole mounting ring, opposite side vertically connects the second fixed mount by one piece of connecting panel, and the 3rd fixed mount is located at manhole plate top;
Depression bar is a circular arc knee, and its one end and middle part to be located at respectively between the second fixed mount and two pieces of risers of the 3rd fixed mount and to be bolted, and the depression bar other end is with the opening briquetting of an annular arrangement, and this opening briquetting upper end is concave ball surfaces;
Clamping screw one end is through being bolted the two pieces of risers being located at the first fixed mount after opening briquetting, and the other end of clamping screw is positioned at opening briquetting top;
Handle nut is located at opening briquetting top and is connected with opening briquetting by the clamping screw in opening briquetting, and the counterface of handle nut bottom is the spherical shape corresponding with opening briquetting upper end concave ball surfaces.
Described manhole latching device, is characterized in that: locating bush is equipped with in the depression bar one end be located in the second fixed mount.
Described manhole latching device, is characterized in that: the junction of manhole plate and manhole mounting ring is provided with seal ring.
Described manhole latching device, is characterized in that: be bolted between connecting panel and the second fixed mount or be welded to connect.
The beneficial effects of the utility model are: have more accurate polarization after being coordinated by sphere-contact, there will be the phenomenon of skidding and getting loose in no instance, when being namely the pressure increase in tank body, also can ensure can not skid between handle nut and opening briquetting, can not produce relative fortune, such manhole locking improves the reliability and safety that just ensure that production.
Simultaneously such improvement also can meet has the manhole of certain pressure also can use this technology, and the structure of the manhole before opened soon can only use at ambient pressure, can exceed normal pressure or middle pressure also can use after improvement.
After improving, the locking mechanism of manhole is simple, is easy to manufacture, uses the features such as more reliable, safer.
The lock portion present situation of all manholes can be replaced completely, serve more widely need manhole equipment above.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the main apparent direction of the utility model.
