Abstract
The utility model relates to the field of flange hand holes, in particular to a quick hand hole opening device characterized by including a hand hole cover, a pressure bearing belt, a lug bolt and a locking handle, wherein the pressure bearing belt is arranged at the top of the hand hole cover, one end of the pressure bearing belt is hinged with an overturn lug plate on a hand hole side wall, and a lug seat is arranged on a hand hole side wall at the other end of the pressure bearing belt; one end of the lug bolt is hinged with the lug seat, and the other end of the lug bolt is connected with the locking handle through screw threads; and an opening matched with the lug bolt is arranged at the other end of the pressure bearing belt. A sealing belt is arranged between the bottom of the hand hole cover and the upper edge of the hand hole. Compared with the prior art, the quick hand hole opening device has the benefits that a hand hole can be opened and closed more conveniently and quickly, the operation time is saved, the work efficiency can be effectively improved, and the labor intensity is reduced.
Description
Technical field
The utility model relates to flange hand hole field, relates in particular to a kind of hand hole device of opening soon.
Background technique
Mostly tank body in the past or the hand hole on the equipment are flanged connecting structure, and each unlatching all need be unclamped the bolt of fastening flange lid, when hand hole is closed then, bolt is screwed again, and operation is relatively lost time, and labor intensity is also bigger; The sealing of flange is destroyed easily in addition, causes that hand hole leaks.
Summary of the invention
The purpose of the utility model provides a kind of hand hole device of opening soon, overcomes the deficiency of existing technology, and is convenient to disassembly, practices thrift the time of switch hand hole, reduces labor intensity.
For solving the problems of the technologies described above, the technological scheme of the utility model is:
A kind of hand hole device of opening soon; Comprise hand hole cover, pressure-bearing band, ring ear snail bolt and set lever, the pressure-bearing band is located at the top of hand hole cover, and the upset otic placode on pressure-bearing band one end and the hand hole sidewall is hinged; The hand hole sidewall of the pressure-bearing band the other end is provided with the ear seat; One end and the ear seat of ring ear snail bolt are hinged, and the other end of ring ear snail bolt is threaded with set lever, and the pressure-bearing band the other end is provided with and encircles the opening of ear snail bolt coupling.
Be provided with sealing strip between the bottom of said hand hole cover and the upper edge of hand hole.
Compared with prior art, the beneficial effect of the utility model is: make opening and closing more convenient and quicker, the saving operating time of hand hole, can increase work efficiency effectively, reduce labor intensity.

Embodiment
Describe in further detail below in conjunction with the embodiment of accompanying drawing the utility model.
See Fig. 1, Fig. 2; It is a kind of structural representation of opening hand hole device embodiment soon of the utility model; Comprise hand hole cover 1, pressure-bearing band 9, ring ear snail bolt 5 and set lever 6, pressure-bearing band 9 is located at the top of hand hole cover 1, and the upset otic placode 3 on pressure-bearing band 9 one ends and the hand hole sidewall is hinged through bearing pin 1; The hand hole sidewall of pressure-bearing band 9 the other ends is provided with ear seat 4; One end and the ear seat 4 of ring ear snail bolt 5 are hinged through bearing pin 28, and the other end of ring ear snail bolt 5 is threaded with set lever 6, and pressure-bearing band 9 the other ends are provided with and encircle the opening of ear snail bolt 5 couplings.
Be provided with sealing strip between the upper edge of the bottom of hand hole cover 1 and hand hole 2.
When opening this hand hole, only need set lever 6 is unscrewed, ring ear snail bolt 5 is put down around bearing pin 28, hand hole cover 1 can be opened around bearing pin one 7 upsets like this.Hand hole cover 1 is got back on the hand hole 2 around bearing pin one 7 returning buckles again when closing hand hole, and ring ear snail bolt 5 is gone to the opening of pressure-bearing band 9 the other ends round bearing pin 28, and the set lever 6 of screwing can fastening hand hole cover 1, accomplishes a folding and operates.
Claims (2)
1. open the hand hole device soon for one kind, it is characterized in that, comprise hand hole cover, pressure-bearing band, ring ear snail bolt and set lever; The pressure-bearing band is located at the top of hand hole cover; Upset otic placode on pressure-bearing band one end and the hand hole sidewall is hinged, and the hand hole sidewall of the pressure-bearing band the other end is provided with the ear seat, and an end and the ear seat of ring ear snail bolt are hinged; The other end of ring ear snail bolt is threaded with set lever, and the pressure-bearing band the other end is provided with and encircles the opening of ear snail bolt coupling.
