Description
Technical Field
The utility model relates to a gas meter connector, in particular to a gas meter connector of an indoor gas pipeline, and belongs to the technical field of gas pipe connection.
Background
In order to realize the overall tightness detection of an indoor gas pipeline, the Chinese patent document with the patent number of CN201320735675.1 discloses a pressure measuring meter connector which comprises a nut, wherein a pressure measuring meter connector body is arranged in the nut in a penetrating manner, the middle part of the pressure measuring meter connector body is transversely provided with a valve core device, the valve core device comprises a valve core body transversely arranged in the pressure measuring meter connector, one end of the valve core body is provided with a nut in a matching manner, and a second gasket is arranged between the valve core body and the nut; the technical scheme of this patent is through the valve inside device that connects body one side to set up at the pressure gauge, can test the atmospheric pressure size in the gas pipeline to adjust the test gas pipeline internal gas pressure. However, in order to avoid interference when the valve core device is assembled with the nut, the meter connector cancels a pressure measuring interface step and adopts a metal retainer ring structure instead. And the check ring type structure is complex to assemble, the operation difficulty is high and the safety is low. On the other hand, the size of the assembly retainer ring needs to be reserved when the retainer ring type structure is installed, the size of the connector body is large, and the cost is high.
Disclosure of Invention
The utility model aims to provide the gas meter connector which not only properly solves the problem of nut assembly interference but also is convenient to assemble through structural optimization aiming at the defects in the prior art.
In order to achieve the purpose, the technical scheme of the utility model is as follows: a gas meter connector comprises a tubular connector main body, wherein one end of the connector main body is provided with an expanding step ring for pressing and holding a nut, and a pressure measuring interface for installing a valve core radially extends out of the middle part of the connector main body in the length direction;
one end of the nut is provided with a reducing pressing ring, the reducing pressing ring is provided with a pair of radial notches for dividing the reducing pressing ring into two semicircular arcs, and the maximum opening distance of the pair of radial notches is larger than the outer diameter of the diameter expanding step ring;
the outer surface of one of the two semi-circular arcs is provided with an inner inclination angle which enables the reducing pressing ring of the nut to be inserted through the radial gap in a sliding mode.
Therefore, when the nut is assembled, the reducing pressing ring of the nut is inclined relative to the joint body, is obliquely inserted into the radial gap along the surface with the inward inclination angle, and vertically presses and holds the diameter expanding step ring of the joint body, so that the nut is very convenient.
Therefore, the beneficial effects of the utility model are as follows: the problem of assembly interference can be properly solved only through the offset radial gap of the nut without a retainer ring structure, the structure is simple, the assembly is convenient, and the safety is guaranteed; the size of the assembly check ring is not required to be reserved during installation, the length of the meter connector body is reduced, materials are saved, and cost is reduced.
The utility model has the further perfection that: the pressure measuring connector is provided with an inner hole with a conical section for installing the valve core, and the outer end of the pressure measuring connector is provided with a threaded port for screwing the plug cover.
The utility model has the further perfection that: the axial outer surface of the nut is formed by hexagonal sections and ring ends.
The utility model has the further improvement that: the inner inclination angle is 20-25 °

Detailed Description
Example one
As shown in fig. 1, the gas meter connector for an indoor gas pipe of the present embodiment is composed of a nut 1, a connector body 2, a valve core 3, a plug 4, and a gasket 5.
As shown in figure 2, one end of the joint main body 2 in a tubular shape is provided with an expanding step ring 2-1 used for pressing and holding a nut, the middle part of the joint main body 2 in the length direction radially extends out of a pressure measuring interface 2-2, the pressure measuring interface 2-2 is provided with an inner hole with a conical section used for installing a valve core 3, and the outer end is provided with a threaded port 2-3 used for screwing a plug cover 4.
As shown in figures 3 to 5, the axial outer surface of the nut 1 is composed of a hexagonal section 1-4 and a ring end 1-5, the other end far away from the ring end is provided with a reducing pressing ring 1-3, the reducing pressing ring 1-3 is provided with a pair of radial gaps 1-2 dividing the reducing pressing ring into two semicircular arcs, and the maximum opening distance of the pair of radial gaps 1-2 is larger than the outer diameter of the expanding step ring 2-1.
The outer surface 1-1 of one of the two semi-circular arcs has a 20-25 DEG inclination angle for sliding the expanding step ring 2-1 of the joint body 2 through the radial gap 1-2. Namely, the end surface of the nut 1 is asymmetric at two sides of the radial gap 1-2, one side is horizontal, and the other side forms an included angle of 20-25 degrees with the horizontal plane.
