Abstract
The utility model provides an on-vehicle hydrogen tank valve of exchange formula and trachea butt joint locking structure, including valve and trachea joint, the valve have the round cross-section to be trapezoidal recess at its kneck, the trachea connector include connector dustcoat, jump ring, steel ball, spring and connector body, connector dustcoat cover on the connector body, the jump ring block on the connector body when the connector equipment, the steel ball place in the round hole of connector body, the spring housing on the connector body, the initial state is that the spring slightly bears the pressure, the connector body realize the gas circuit intercommunication with the valve butt joint. The structure has simple and convenient operation, firm and stable structure and convenient and rapid disassembly; the utility model discloses low cost is very practical.
Description
Technical Field
The utility model relates to a valve and gas circuit butt joint locking structure especially relate to an on-vehicle hydrogen tank valve of exchange and trachea butt joint locking structure.
Background
At present, the valve and the air pipe are connected by hand and are usually butted and screwed, the installation is difficult, the disassembly is difficult, and meanwhile, accidents are easy to occur.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides a safe, the operation of being convenient for, easily connect locking and easily dismantled locking structure.
The utility model provides a valve and gas circuit butt joint locking structure, include: the valve comprises a valve and a gas pipe connector, wherein a circle of groove with a trapezoidal section is formed at the interface of the valve, the gas pipe connector comprises a connector outer cover, a clamp spring, a steel ball, a spring and a connector body, the connector outer cover is sleeved on the connector body, the clamp spring is clamped on the connector body when the connector is assembled, the steel ball is placed in a circular hole of the connector body, the spring is sleeved on the connector body,
the spring is slightly compressed in the initial state,
the connector body is in butt joint with the valve to realize gas circuit intercommunication.
Compared with the existing butt joint structure of the valve and the air pipe, the structure can realize quick butt joint and locking of the valve and the air pipe; quick disassembly is also possible.
Drawings
FIG. 1 is a perspective exploded schematic view of an example of the present invention;
FIG. 2 is a schematic cross-sectional view of the operating state;
FIG. 3 is a schematic cross-sectional view of the separated state;
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The utility model discloses a preferred embodiment is shown in fig. 1 to fig. 3, an on-vehicle hydrogen tank valve of exchange formula and trachea butt joint locking structure, including valve (1) and trachea connector, the valve have the trapezoidal recess of round at the kneck, the trachea connector include connector dustcoat (2), jump ring (3), steel ball (4), spring (5) and connector body (7), connector dustcoat (2) cover on connector body (7), jump ring (3) block on connector body (7) when the connector equipment, steel ball (4) place in the round hole of connector body (7), spring (5) cover on the connector body.
The spring (5) is slightly compressed in the initial state.
The valve (1) and the connector body (7) are in butt joint to realize air passage intercommunication.
When the connector outer cover (2) moves backwards to extrude the spring (5), the steel balls (4) slide out of the connector body (7) for limiting; the whole connector is butted with the valve (1), the outer cover (2) of the air pipe connector is loosened, and the spring (5) rebounds to return the steel ball (4) to the original position; the steel ball (4) is clamped with the groove of the contact point of the valve (1), so that the locking purpose is achieved.
When the outer ring (2) of the connector moves backwards to extrude the spring (5) and the steel balls (4) slide out of the connector body (7) for limiting, the connector integrally retreats and is loosened from the valve (1), and the purpose of disassembly is achieved.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
Claims (3)
1. A switching type vehicle-mounted hydrogen tank valve and air pipe butt joint locking structure is characterized by comprising a valve and an air pipe connector, wherein a circle of groove with a trapezoidal section is formed in a joint of the valve, the air pipe connector comprises a connector outer cover, a clamp spring, a steel ball, a spring and a connector body, the connector outer cover is sleeved on the connector body, the clamp spring is clamped on the connector body when the connector is assembled, the steel ball is placed in a round hole of the connector body, the spring is sleeved on the connector body, and when the connector outer cover moves backwards, the spring extrudes the steel ball to slide out of a limit position of the connector body; the whole connector is butted with the valve, the outer cover of the air pipe connector is loosened, and the spring rebounds to return the steel balls to the original position; the steel ball is clamped with the groove of the contact point of the valve, so that the locking purpose is achieved; when the outer ring of the connector moves backwards to extrude the spring steel balls to slide out of the limit of the connector body, the connector integrally retreats and is loosened with the valve, and the purpose of disassembly is achieved.
2. The structure of claim 1, wherein the spring is under slight pressure in the initial state when the spring is fitted over the connector body.
3. The exchange type vehicle-mounted hydrogen tank valve and gas pipe butt joint locking structure as claimed in claim 1, wherein the connector body is characterized in that gas circuit intercommunication is realized by butt joint with the valve.
