Abstract
The utility model discloses a gas steering joint subassembly with stop device, including outer hexagon nut, interior hexagonal connector and 90 adapters, the inside of 90 adapters is provided with the internal thread, outer hexagon nut passes through interior hexagonal connector with in 90 adapters interior thread threaded connection, interior hexagonal connector with be provided with O shape circle between 90 adapters the inside spacing boss of second that is provided with of 90 adapters, highly being less than of spacing boss O shape circle's thickness, 90 adapters are in the internal thread bottom is provided with the surplus space that remains. The utility model discloses except adopting the brass material to increase structural strength, set up spacing boss of second and first spacing boss respectively in the position of O shape circle, sealing washer, both avoided because the too big damage that leads to O shape circle and sealing washer of installation moment of torsion, also can keep O shape circle and sealing washer at the best compression volume when the installation.
Description
Technical Field
The utility model relates to a gas connects technical field, especially relates to a gas steering joint subassembly with stop device.
Background
Household gas appliances often require the use of a steering joint due to installation space limitations. The inside steering joint more uses outside hexagon nut to join in marriage 90 adapter two segmentation structures of collocation again and uses sealed pad in the trade at present, and nut and adapter use the die-casting of zinc alloy material to form, but the zinc alloy material is more fragile, when installer uses great strength installation, leads to breaking easily and produces the gas leakage hidden danger. Therefore, in the industry, a nut and a steering joint are made of brass, but due to processing limitation, an inner hexagonal connector needs to be added on the basis of an original 90-degree adapter, and the inner hexagonal connector is connected with the 90-degree adapter through threads, and the rear end of the inner hexagonal connector is sealed through an O-shaped ring. Although the structure is strong, the phenomenon that the O-shaped ring is crushed by overlarge installation torque to cause air leakage occurs during actual installation.
The person skilled in the art is dedicated to solving the above technical drawbacks.
SUMMERY OF THE UTILITY MODEL
In view of the above-mentioned drawbacks of the prior art, the technical purpose of the present invention is to solve the problems mentioned in the background art.
For realizing the technical purpose, the utility model provides a gas steering joint subassembly with stop device, including outer hexagon nut, interior hexagon connector and 90 adapters, the inside of 90 adapters is provided with the internal thread, outer hexagon nut passes through interior hexagon connector with in 90 adapters interior thread threaded connection, interior hexagon connector with be provided with O shape circle between 90 adapters 90 the inside spacing boss of second that is provided with of adapter, spacing boss highly be less than the thickness of O shape circle, 90 adapters are in the internal thread bottom is provided with the surplus space, outer hexagon nut's inboard is provided with the sealing washer, the interior hexagon connector corresponds the tip of sealing washer is provided with first spacing boss.
Preferably, outer hexagon nut the hexagon socket head and 90 adapter all adopt the brass material to make.
The utility model has the advantages that:
the utility model discloses because above-mentioned structural design, except adopting the brass material to increase structural strength, set up spacing boss of second and first spacing boss respectively in the position of O shape circle, sealing washer, both avoided because the too big damage that leads to O shape circle and sealing washer of installation moment of torsion, also can keep O shape circle and sealing washer at the best compression volume when the installation.
Drawings
FIG. 1 is a schematic sectional view of the present invention;
FIG. 2 is a schematic plan view of the present invention;
fig. 3 is a schematic view of the three-dimensional structure of the present invention.
In the figure: the structure comprises an outer hexagon nut 1, a sealing ring 2, an inner hexagon connector 3, a first limiting boss 31, an O-shaped ring 4, a 590-degree adapter, a second limiting boss 51 and a remaining space 52.
Detailed Description
The conception, the specific structure and the technical effects of the present invention will be further described with reference to the accompanying drawings, so as to fully understand the objects, the features and the effects of the present invention.
Example (b):
as shown in fig. 1-3, a gas steering joint assembly with a limiting device, including outer hexagon nut 1, inner hexagon connector 3 and 90 adapter 5, the inside of 90 adapter 5 is provided with the internal thread, outer hexagon nut 1 is through the internal thread threaded connection in inner hexagon connector 3 and 90 adapter 5, be provided with O shape circle 4 between inner hexagon connector 3 and the 90 adapter 5, be provided with the spacing boss 51 of second in 90 adapter 5 inside, the thickness that highly is less than O shape circle 4 of spacing boss 51, 90 adapter 5 is provided with surplus space 52 in the bottom of internal thread, the inboard of outer hexagon nut 1 is provided with sealing washer 2, the tip that inner hexagon connector 3 corresponds sealing washer 2 is provided with first spacing boss 31.
Specifically, the hexagon nut 1, the inner hexagon connector 3 and the 90-degree adapter 5 are all made of brass.
Specifically, the height of the second limit boss 51 is lower than the thickness of the O-ring 4 when the O-ring is naturally installed, and as is known, the compression amount of the O-ring 4 is kept within a certain range, so that the sealing effect is ensured and the O-ring is not lost, therefore, after the second limit boss 51 is arranged, when the hexagon socket head 3 is rotatably installed to the bottom through the threads, the end face of the second limit boss 51 falls on the second limit boss, and the compression amount of the O-ring 4 is ensured to be in an optimal state.
Specifically, in order to provide sufficient deformation space for the compressed O-ring 4, a remaining space 52 is provided at the bottom of the internal thread of the 90 ° adapter 5.
Specifically, in order to ensure that the compression amount of the sealing ring 2 is within a reasonable range, the first limiting boss 31 is also arranged at the end part of the inner hexagonal connector 3, so that the inner hexagonal connector 3 is not damaged due to overlarge installation torque when being connected with a gas appliance.
The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the teachings of the present invention without undue experimentation. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
