Abstract
The utility model discloses an anti-explosion leakage-proof filter flask which comprises a body and an upper cover. Outer threads are formed at the opening of the body. Inner threads are formed on the inner side of the upper cover. The body and the upper cover are integrally connected through the outer threads and the inner threads. A groove for placing a seal ring is further formed at the opening of the body. The thread section of the outer threads is trapezoid. The thread section of the inner threads is trapezoid. The inner edge of the groove is higher than the outer edge of the groove. The outer diameter of the inner edge of the groove is larger than the inner ring diameter of the external seal ring. The anti-explosion leakage-proof filter flask has the advantages that threaded connection is achieved through the threads with the trapezoid thread sections, high pressure resistance is achieved, the threads are less prone to deformation, product service cycle is increased, the seal ring disposed in the groove is less prone to falling, and convenient mounting is achieved.
Description
Technical field
The utility model belongs to the filter flask field of filtering, particularly a kind of filter flask that can antiknock leakproof.
Background technology
Filter flask is in family, hotels and other places is widely used, filter flask comprises bottle and upper cover, bottle and upper cover are to be threaded connection all-in-one-piece, the rectangular shape in screw thread thread cross section that domestic filter flask is threaded at present, the pressure resistance that rectangle thread bears is very limited, once pressure is excessive, leaking or explosion just may appear in filter flask, in order to address this problem, someone proposed to realize and being threaded with the screw thread of triangle thread afterwards, this has improved pressure resistance to a certain extent, can bear larger pressure, but the most advanced and sophisticated stressed excessive distortion that is easy to of thread, can not meet operating needs, when the seal ring of existing filter flask is installed under inclination or inversion state simultaneously, easily drop, install and bring great inconvenience to filter flask.
The technical problems to be solved in the utility model is to provide the improvement filter flask that a kind of pressure resistance is strong and thread is not yielding, leak resistance is good.
Utility model content
For solving the problems such as above-mentioned prior art pressure resistance is little, leak resistance is poor, use is inconvenient, the utility model adopts following technical scheme:
The utility model provides a kind of antiknock leakproof filter flask, comprise bottle and upper cover, bottle mouth position at described bottle is provided with outside thread, be provided with negative thread in described upper cover inner side, described bottle, upper cover are threaded in aggregates by outside thread with negative thread, also be provided with the groove of placing seal ring at the bottle mouth position of described bottle, described externally threaded thread cross section is echelon form, the thread cross section of described negative thread is echelon form, the interior rock of described groove is higher than outer rock, and in described groove, rock external diameter is greater than the inner ring diameter of external seal ring.
As to improvement of the present utility model, intersection, all two sides of the internal structure external structure of described bottle is the transition of circular arc R angle.
As to further improvement of the utility model, intersection, all two sides of the internal structure external structure of described upper cover is the transition of circular arc R angle.
The beneficial effects of the utility model are: adopt the screw thread realization of echelon form thread to be threaded, pressure resistance is strong, and thread is not yielding, improve product operating cycles, and to the processing of seal ring standing groove, seal ring is difficult for dropping, and installs more convenient.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Fig. 2 is the structural representation in outside thread thread cross section in the utility model.
Detailed description of the invention
Describe preferred embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Refer to Fig. 1, a kind of antiknock leakproof filter flask, comprise bottle 1 and upper cover, be provided with outside thread 11 at the bottle mouth position of described bottle 1, be provided with negative thread 21 in described upper cover 2 inner sides, described bottle 1, upper cover 2 is threaded in aggregates by outside thread 11 with negative thread 21, also be provided with the groove 12 of placing seal ring at the bottle mouth position of described bottle 1, the thread cross section of described outside thread 11 is echelon form, the thread cross section of described negative thread 21 is echelon form, the concrete schematic diagram in outside thread thread cross section refers to Fig. 2, negative thread thread cross sectional shape is the same with outside thread, the pulling force that the thread of echelon form can bear is larger, pressure resistance is stronger, and the screw thread thread cross section of traditional filter flask is rectangle or leg-of-mutton, pressure resistance is all limited, after pressure acquires a certain degree, be easy to leak even explosion, the interior rock of described groove is higher than outer rock, in described groove, rock external diameter is greater than the inner ring diameter of external seal ring, seal ring will be fastening be enclosed within groove on rock, when installation, filter flask is in tilting or inversion state, seal ring is difficult drop-off also, and the inside and outside rock height of traditional groove is the same, filter flask is in the time tilting or be inverted, seal ring is easy to drop, give to install and use and bring very large inconvenience.
In the utility model, the intersection, all two sides of internal structure external structure of described bottle 1 is the transition of circular arc R angle, the intersection, all two sides of internal structure external structure of described upper cover 2 is the transition of circular arc R angle, intersection, all two sides all adopts the transition of circular arc R angle, can effectively improve the pressure resistance of filter flask, harsher environment can satisfy condition.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, suitable variation or modification that any person of an ordinary skill in the technical field does it, all should be considered as not departing from patent category of the present utility model.
