The utility model relates to a gas-fire security connecter with switches and automatic lock, comprising screw stuff and a steel bottle tie-in. The cavity is provided with a spring, a copper sphere, a seal glue circle, three heteromorphic O-shaped glue circle and the front part of the connection cover. An active insert core with a central venthole is arranged on the front part of the connection cover whose middle part is provided with switches and a pull board on the below part to let the active insert core move forwards or backwards. With the movement of the insert core, the open and close of the gas channel is realized. The back part of the steel bottle tie-in is provided with an automatic lock device and the automatic lock between the connection cover and the steel bottle tie-in is realized via the mutual cooperation between an active ring, a block slot on the back part of the tie-in, keys and the handle. The connecter has the advantages of convenient manipulation, easy connection, hermetic and credible and safe use.
Description
The utility model relates to gas cylinder and combustion gas tool interconnection technique field, particularly a kind of belt switch, self-locking gas safe connector.
Existing a kind of gas safe quick connector partly is made up of cylinder joint part and fast joint, cylinder joint partly comprises the steel cylinder plug, plug screw, cylinder joint, be contained in the turriform spring in plug screw Inner chamber, copper sphere, seal gasket, fast joint partly comprises the outer cover of opening, fittings body, interior top cover, steel ball and elastic spring, outer casing spring, interior sleeve spring, adapter sleeve, anterior and the central plunger tip that the band center roof vent is housed in place, cylinder joint rear portion at adapter sleeve, this plunger tip front end contacts with the sphere of copper sphere, its side is provided with a plurality of air admission holes, the plunger tip rear portion is threaded with adapter sleeve and is integral, and the plunger tip middle front part that is slidingly matched with cylinder joint is provided with three O type rubber seal.There is following weak point in this connector: 1. adapter sleeve is with after cylinder joint is connected, and blast tube is in normal open state, like this, finishes with gas and will close cylinder angle valve, and troublesome poeration, angle valve are also fragile.When 2. adapter sleeve was connected with cylinder joint, in general angle valve was in opening state, and copper sphere will bear 6kg pressure, will spend than great strength so back down copper sphere when the plunger tip insertion.3. because the cylinder joint rear portion is that cylinder is connected with plunger tip, also there is the gap between them, when adapter sleeve is subjected to can occur under the external force effect swing, three O RunddichtringOs of plunger tip middle front part, should seal and bear active force again, thereby easily make the sealing ring distortion, may cause gas leakage.
The purpose of this utility model be to provide a kind of easy to operate, connect light and handy, reliable sealing belt switch, self-locking gas safe connector.
The purpose of this utility model is achieved in that a kind of belt switch, self-locking gas safe connector, comprise the steel cylinder pad (1) that is connected with the cylinder angle valve gas outlet, plug screw (2), cylinder joint (3), be contained in the turriform spring (24) in cylinder joint (3) Inner chamber, copper sphere (23), seal gasket (4), three sealing O type cushion rubbers (21), and the adapter sleeve that is threaded with pressure regulator valve (18), this adapter sleeve (18) is anterior to be tightly connected mutually with three the sealing O type cushion rubbers (21) that are positioned at cylinder joint (3) rear portion, anterior blast tube Inner is equipped with the movable lock pin (5) of being with center roof vent at adapter sleeve (18), between adapter sleeve (18) front portion and the movable lock pin (5) back-moving spring (19) is housed; Described adapter sleeve (18) middle part is provided with switch (14), and its group pulled (17) and movable lock pin (5) back end in contact; Be provided with the self-locking mechanism (9) that is fastenedly connected with adapter sleeve (18) at cylinder joint (3) rear portion, its locking loose collar (7) is matched with the draw-in groove that is located at cylinder joint (3) rear portion.Described switch (14) is made up of handle (13), rotating shaft (15), sealing O type cushion rubber (16), group plate (17), rotating shaft (15) is tightly connected by sealing O type cushion rubber (16) and adapter sleeve (18), rotating shaft (15) top is provided with handle platform (11) and limited mouth (12), and rotating shaft (15) lower end is provided with dials plate (17).Described self-locking mechanism (9) is made up of button (10), locking jacket (6), locking loose collar (7), limiting plate (20), spring (8).
Advantage of the present utility model is: when 1. being in connection status, because air flue is provided with on-off switch, thus do not need to close angle valve finishing with gas, easy to operate.2. be connected light and handy between cylinder joint and the adapter sleeve.3. the cylinder joint posterior face is that the conical surface is connected with the locking jacket inner face, and no gap can not swung, and all supporting forces are born by the conical surface, and sealing O type cushion rubber 21 seals merely, can not produce distortion, so sealing is reliable, safe in utilization.
Fig. 1 is the structural representation of an embodiment of the utility model.
By following embodiment the utility model is further elaborated.
Referring to shown in Figure 1, a kind of switch of embodiment of the utility model, self-locking gas safe connector, include the steel cylinder pad 1, plug screw 2, the cylinder joint 3 that are connected with the cylinder angle valve gas outlet, at plug screw 2 inner chambers turriform spring 24, copper sphere 23, seal gasket 4 are housed, cylinder joint 3 rear portions are embedded with three sealing O type cushion rubbers 21; Adapter sleeve 18 anterior external cylindrical surfaces and cylinder joint 3 rear portions are slidingly matched, and its inner cylinder face is slidingly matched with the movable lock pin 5 of band central through hole, between the adapter sleeve 18 anterior Inner faces of cylinder and movable lock pin 5 external cylindrical surfaces back-moving spring 19 is housed; Be provided with switch 14 at adapter sleeve 18 middle parts, blast tube is carried out Push And Release, this switch 14 is made up of handle 13, rotating shaft 15, sealing O type cushion rubber 16, group plate 17, rotating shaft 15 is tightly connected with adapter sleeve 18 by two sealing O type cushion rubbers 16, rotating shaft 15 tops are provided with handle platform 11 and limited mouth 12, and rotating shaft 15 lower ends are provided with group plate 17 and contact with movable lock pin 7 rear ends; Cylinder joint 3 rear portions are provided with self-locking mechanism 9, it is made up of button 10, locking jacket 6, locking loose collar 7, limiting plate 20, spring 8, locking jacket 6 is fastening by bolt 22 and adapter sleeve 18, and locking loose collar 7 originally connects with the draw-in groove that is located at cylinder joint 3 rear portions.Cylinder joint 3 is connected with cylinder angle valve, adapter sleeve 18 is with after pressure regulator valve is threaded, when adapter sleeve 18 inserts cylinder joint 3, locking loose collar 7 locking cylinder joints 3, at this moment, dial plate 17 perpendicular to adapter sleeve 18 axis, promptly movable lock pin 5 moves after under back-moving spring 19 effects, copper sphere 23 compresses seal gasket 4, the blast tube locking.When needing ventilation, by means of limiting plate 20, handle 13 is rotated 90 ° of angles, at this moment, dial plate 17 and be parallel to adapter sleeve 18 axis, it is stirred front end and is provided with the movable lock pin 5 of a plurality of ventholes and drives copper sphere 23 reaches and open blast tube, at this moment, the limited mouth 12 of handle 13 leaves and the relative position of button 10 beads, removes to lock button 10 by handle platform 11, promptly locks loose collar 7 fastening cylinder joints 3.Locking loose collar 7 tops are equipped with spring 8 and are made locking loose collar 7 often be in locking state.
