Abstract
The invention discloses a storage tank manhole which comprises a flange mounted on the side wall of a storage tank and a manhole cover parallelly arranged on one side of the flange. A catch holder is welded to the outer top wall of the manhole cover and is provided with a catch, the top of the catch is connected to an L-shaped catch moving rod, and the other end of the catch moving rod is inserted in a rod seat on the outer side wall of the flange and is of degree of freedom of rotation along an axial direction of the wall of the rod seat. The storage tank manhole is simple in structure and convenient to manufacture. By means of the L-shaped catch moving rod, connection structure between the flange and the manhole cover is strengthened, thus the storage tank manhole is more stable and safer in use.
Description
Technical field
The present invention relates to a kind of storage tank accessory, be specifically related to a kind of storage tank manhole.
Background technology
In pharmacy, chemical industry and other relevant industries, often to use many storage tanks, for the convenient internal washing to storage tank, in reservoir container, generally all can offer manhole device, with the manhole by this manhole device, internal tank is overhauled to box and clean.Manhole device is provided with manhole cover, and the opening ways of manhole cover is hinge-type and screw rod hoisting type, although the former is simple and convenient, safety performance is not high, although the latter's safety performance is high, operates cumbersomely, wastes time and energy.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, storage tank manhole a kind of simple in structure, safe and convenient to use is provided.
A storage tank manhole, comprises the flange being arranged on storage tank sidewall, and the manhole cover that is set in parallel in this flange one side; On the outer roof of described manhole cover, be welded with hook bar, hook bar is risen to the bait and is provided with hook, and the top of hook is connected on hook portable bar, and hook portable bar is L-type, the other end is inserted in the pole socket of flange lateral wall, and has along the degree of freedom of pole socket wall axial-rotation.
The opposite side of described manhole cover is provided with handle.
The present invention is simple in structure, easily manufactured, links up with the setting of portable bar by L-type, has strengthened the connection structure of flange and manhole cover, makes it more firm in use, safe.
