A tapered sealing body is arranged at a pipe opening, located in an inner cavity of the shell, of the pipe connector in a sliding mode, and the rear end of the tapered sealing body makes contact with the front end face of the cylindrical rotating handle and is limited in the radial direction through a limiting pin. A safety handle is hinged to the outer wall of the shell, the outer circumferential surface, located in front of the safety handle, of the shell is sleeved with a clamping sleeve in a sliding mode, and a pressure spring is arranged between the clamping sleeve and the shell. A plurality of round holes and steel balls are arranged on the circumferential surface of the front end of the shell at intervals, wherein the steel balls are arranged in the round holes, and annular grooves are formed in the positions, corresponding to the steel balls, of the outer circumferential surface of the ejector rod. The inner circumferential surface of the front end of the clamping sleeve makes contact with the steel balls in a rolling mode. The filling device has the advantage that the filling device can be rapidly connected with or separated from a filled device by rapidly compressing or releasing the steel balls.
Description
Technical field
The utility model relates to the Filling apparatus for gas or liquid, especially relates to and has the Filling apparatus that auto lock connects fast.
Background technique
At present, domestic existing Filling apparatus is the Filling apparatus that is threaded with load mechanism for detaching, and this structure is mainly made up of free flow coupling and housing, between the two, connects by screw thread.The deficiency of its existence is: adopt thread forms and be filled with device and be connected, connection speed is slower; Load removal gas circuit contacts by the rigidity between steel ball and piston rod that to realize gas circuit airtight, and required sealing load is larger, and sealing realizes comparatively difficulty; The function that what device possessed can discharge is filled with residual gas in device or liquid is in the time of operate miss, and the sealing mechanism that makes to be filled with in device can not normally seal, and causes to be filled with in device gas or leak of liquid is even lost its function.
Summary of the invention
The utility model object is to provide a kind of Filling apparatus that auto lock connects fast that has.
For achieving the above object, the utility model is taked following technical proposals:
Described in the utility model have a Filling apparatus that auto lock connects fast, comprises the housing of cylinder hollow structure, is arranged on the push rod at described housing front port place and the rotating cylindrical handle at rear port place, and is arranged on the pipe joint in housing sidewall; Slide and be provided with cone seal body in the mouth of pipe place that described pipe joint is positioned at housing inner chamber, described cone seal body rear end contacts with described rotating cylindrical handle front-end face and to pass through position limit pin radially spacing; On housing outer wall, be hinged with safety handle, be positioned at flip sleeve on the housing outer circumferential face in described safety handle front cutting ferrule is housed, between described cutting ferrule and housing, be provided with pressure spring; Housing front end side face interval has multiple circular holes and steel ball extremely in the inner, has annular groove at described push rod outer circumferential face corresponding to described steel ball place; Described cutting ferrule front end inner peripheral surface contacts with steel ball rolling.
The utility model advantage is by fast-holding and loosens described steel ball and can realize and be filled with the quick of device and be connected and removal, and load removal function and safety handle, again for the realization connecting fast provides guarantee.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the Filling apparatus with the quick connection of auto lock described in the utility model, comprise the housing 2 of cylinder hollow structure, be arranged on the push rod 6 at described housing 2 front port places and the rotating cylindrical handle 1 at rear port place, and be arranged on the pipe joint 5 on housing 2 sidewalls; Slide and be provided with cone seal body 3 in the mouth of pipe place that described pipe joint 5 is positioned at housing 2 inner chambers, described cone seal body 3 rear ends contact with described rotating cylindrical handle 1 front-end face and to pass through position limit pin 4 radially spacing; On housing 2 outer walls, be hinged with safety handle 10, be positioned at flip sleeve on housing 2 outer circumferential faces in described safety handle 10 fronts cutting ferrule 9 is housed, between described cutting ferrule 9 and housing 2, be provided with pressure spring 8; Housing 2 front end side face intervals have multiple circular holes and steel ball 7 extremely in the inner, offer annular groove at described push rod 6 outer circumferential faces corresponding to described steel ball 7 places; Described cutting ferrule 9 front end inner peripheral surfaces roll and contact with steel ball 7.
The utility model working principle is summarized as follows:
In the time of rotating cylindrical handle 1, make cone seal body 3 produce translation, control cone seal body 3 with housing 2 conical surface close contacts or separate, thereby realizing the opening and closing of load removal gas circuit.Pipe joint 5 one end are threaded connection on housing 2, and the other end is connected with source of the gas or liquid source by screw thread.Safety handle 10 is fixed on by bearing pin 11 on the fixed pedestal of housing 2, can only rotate around bearing pin 11 and can not translation.Produce moment of torsion by safety handle 10 jack-up with the torsion spring 12 of bearing pin 11 concentrics, and the automatically reseting of guarantee insurance handle 10.Cutting ferrule 9 is installed with housing 2 concentrics, the front end that back-up ring is arranged on housing 2 plays and stops that cutting ferrule 9 makes it can not come off from housing 2, pressure spring 8 one end are pressed on the shaft shoulder of housing 2, and the other end is pressed on the shaft shoulder of cutting ferrule 9, and the elastic force of pressure spring 8 automatically resets cutting ferrule 9.Be distributed in the some circular holes of housing 2 front end side face steel ball 7 is installed, steel ball 7 can carry out radial motion, the dimensional changes of circular hole is installed and can in housing 2, drop, the position of the circular hole circumferential variation control steel ball 7 of cutting ferrule 9 during by translation but be limited to.
While using this device, first, rotating cylindrical handle 1, is pressed on cone seal body 3 on housing 2 conical surfaces by screw thread transmission, and load removal gas circuit is closed, and guarantees the sealing of whole gas circuit.Press down safety handle 10 and make the cutting ferrule 9 mobile steel ball 7 that loosens backward, to be filled with device and insert housing 2 inner chambers, loosening cutting ferrule 9 makes it to automatically reset because of pressure spring 8 elastic force, cutting ferrule 9 is pressed into steel ball 7 to be filled with device and to clamp accordingly in groove, making to be filled with device is fixed on housing 2, loosen safety handle 10, safety handle 10 stops that cutting ferrule 9 makes it to retreat after attaching on housing 2 under the elastic force effect of torsion spring 12, to prevent the improper slip between cutting ferrule 9 and housing 2 under what fortuitous event in office, make Filling apparatus and be filled with between device all the time in safety locking state, guarantee to connect reliable and equipment and personal security.When inflation work, gas is in free flow coupling 5 enters housing 2, and pleasant road enters gas cylinder, and after having inflated, charging air inlet switch cuts out automatically.Rotating cylindrical handle 1, cone seal body 3 is pushed in screw thread transmission open, and cone seal body 3 departs from the conical surface of housing 2, and load removal gas circuit is opened, and the inner residual gas of housing 2 is discharged.After load is let out and has been removed, press down safety handle 10 cutting ferrule 9 is moved backward, loosen steel ball 7, can easily unload Filling apparatus.
