Detailed Description
The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings, it being understood that the preferred embodiments described herein are for illustration and explanation of the present utility model only, and are not intended to limit the present utility model.
Examples: as shown in fig. 1 and 2, the gas valve socket joint assembly comprises a gas valve socket 1, a gas valve joint 2, an anti-falling structure 4 and a sealing ring 3 arranged on the lower half part in the gas valve joint 2, wherein the inside of the sealing ring 3 is in a funnel shape with a wide upper part and a narrow lower part; the gas valve socket 1 is provided with a detention part and is connected with the sealing ring 3 through the detention part, the width of the detention part is smaller than the widest part in the sealing ring 3 and is larger than the narrowest part in the sealing ring 3, and the detention part is used for enabling the sealing ring 3 to be extruded and sleeved on the gas valve socket 1; the anti-falling structure 4 is arranged on the upper half part in the gas valve joint 2 and comprises two parts of pressing and clamping, wherein the clamping part is elastic and deformable when stressed and is used for limiting connection with the retention part of the gas valve socket 1, so that the plug-in connector and the joint can be fixedly connected with each other only by one plug-in action.
The connection process comprises the following steps: through the detention portion on the gas valve socket 1, will lock the cooperation with its inside anti-disengaging structure 4 after detention portion gets into gas valve joint 2, and detention portion's specific structure is as follows:
the detention part is a plurality of round convex rings which are connected outside the gas valve socket 1 in a smooth shape and concave parts which are formed by sequentially connecting the plurality of round convex rings.
As shown in fig. 1, the outer surface of the retention part is provided with a plurality of protrusions which are regular up and down, so that the protrusions can prop up the anti-drop structure 4 when entering, the effect of locking and limiting will be generated until the anti-drop structure 4 is recessed, and then the gas valve socket 1 can move forwards but cannot withdraw under the action of the anti-drop structure 4, thereby playing the role of anti-drop.
The structure of the anti-falling structure 4 has the following effect of locking and limiting with the external retention part of the gas valve socket 1:
the clamping part of the anti-falling structure 4 comprises a retaining ring 43 and a plurality of triangular teeth arranged on the inner wall of the retaining ring 43 in a circular equidistant array mode.
The setting through the retaining ring 43 can produce the locking spacing with the concave part of detention portion, specifically: the triangular teeth on the retaining ring 43 are in a flat state (as shown in a part enlarged position in fig. 2) in a normal state, and the inner caliber between the triangular teeth in the state is larger than the diameter of the convex part (round convex ring in a round shape) outside the retaining part, but the retaining ring 43 has elasticity, namely, when the triangular teeth are extruded by the convex part, the triangular teeth are bent downwards, when the convex part passes through the triangular teeth, the triangular teeth slightly elastically retract, and then the end parts of the triangular teeth are connected with the concave part between the convex part and the convex part in a low mode, so that the locking limiting effect (shown in a part enlarged position in fig. 1) is generated.
The sealing ring 3 is used for preventing the gas valve socket 1 from continuously moving forwards, so that the gas valve socket 1 can not move forwards and can not withdraw under the action of the anti-falling structure 4 and the sealing ring 3, the gas valve socket 1 is fixedly connected with the gas valve connector 2, and the sealing ring 3 has the following prevention function:
the length of the sealing ring 3 is greater than half of the length of the gas valve joint, the diameter of the widest part of the interior is four fifths of the diameter of the sealing ring 3, the diameter of the narrowest part is four fifths of the diameter of the widest part, and the length of the narrowest part is two fifths of the whole length of the sealing ring 3.
And because the inside of the sealing ring 3 is in a funnel shape with a wide upper part and a narrow lower part, namely, the detention part on the gas valve socket 1 enters the sealing ring 3 and is limited by the narrowest part, the gas valve socket cannot advance, but at the same time, the detention part entering the sealing ring 3 can be tightly extruded and connected with the inner wall of the sealing ring 3.
And because the gas valve joint 2 is provided with external threads corresponding to the internal sealing ring 3, the gas valve joint is connected with a nut through the external threads, and the retention part can be tightly extruded and connected with the sealing ring 3 after the nut is locked.
The structure and the process for quickly detaching the gas valve socket 1 from the gas valve joint 2 can be realized as follows:
the pressing part of the anti-falling structure 4 comprises a pressing buckle ring 41 and a limiting ring 42 sleeved outside the pressing buckle ring 41, the top of the pressing buckle ring 41 is provided with a blocking end which extends outwards and covers the limiting ring 42, and the limiting ring 42 is embedded in the joint of the top of the gas valve joint 2.
The limiting ring 42 can limit the pressing ring 41 to move downwards only by one end distance, and prevent the pressing ring 41 from falling out of the limiting ring 42, while the distance that the pressing ring 41 can move downwards is enough to contact with a plurality of triangular teeth of the retaining ring 43, and the triangular teeth continuously deform downwards, namely, the inner caliber formed by the plurality of triangular teeth on the retaining ring 43 is larger than the diameter of a detention part (a bulge part), so that the limitation of the triangular teeth on the detention part on the gas valve socket 1 is relieved, and the gas valve socket 1 can be pulled out from the gas valve connector 2, and the operation process is as follows: the blocking end of the pressing ring 41 is pressed to move downwards and keep the pressing ring, then the bottom end of the pressing ring 41 further expands the retaining ring 43, so that the pressing ring 41 is not contacted with the retention part of the gas valve socket 1, but when the gas valve socket 1 is separated and the pressing ring 41 is released, the retaining ring 43 elastically resets and drives the pressing ring 41 to move upwards, and the limiting ring 42 limits the pressing ring 41.
