Description

 The invention relates to mechanical engineering, and in particular to devices for connecting devices, assemblies and mechanisms having a pneumatic or hydraulic actuator, to pneumatic or hydraulic sources through pipelines of a hose or hoses.

 Known devices for detachable connection of pipelines, hoses and hoses through a threaded sleeve, a bend, a fitting, a nipple with a nut and the like (State standards: GOST 8966-75 - GOST 8969-75 - Steel connecting parts with a cylindrical thread for pipelines R 1,6 MPa GOST 13954-74 - GOST 13977-74 - Pipe connections on the outer cone GOST 16039-70 - GOST 16078-70 - Pipe connections on the inner cone GOST 9833-73 - Rubber sealing rings of circular cross section for hydraulic and pneumatic devices) .

 The disadvantage of these devices is that in operation, the disconnection process requires an additional tool and takes a long period of time.

 Known devices for bayonet connection of pipelines, hoses and hoses, comprising a housing with pins installed on it, acting as a stopper, and an adapter with a locking spring telescopically connected to the housing (Political Dictionary, Moscow: Soviet Encyclopedia, 1977, p. 44, Bayonet ) is a prototype.

 The connection can be sealed with an o-ring or various gaskets. The adapter has a slot with a protrusion in which the housing pin-stop is located. Spontaneous disconnection of the connector is prevented by the force of the locking spring due to friction between the stopper pin and the protrusion surface in the adapter slot or by placing the stopper pin in the slot lock made in the form of a recess. To disconnect the connector, it is necessary to depress the spring and remove the pin stopper from the slot.

 The disadvantage of this connector is the low shear and shear strength of the stopper pins, as well as the low reliability of their sealing in the housing, and a decrease in spring stiffness can lead to depressurization of the connector, which reduces operational capabilities.

 Improving reliability and strength by increasing the stiffness of the spring and increasing the size of the pin-stopper, the slots in the adapter leads to an increase in the overall dimensions and weight of the connector, and also increases the force required to depress the spring.

The invention solves the problem of expanding operational capabilities, improving the reliability and strength of the connection with small overall dimensions of the connector, allows you to work in pneumatic or hydraulic systems with a pressure of up to 10 MPa (100 kgf / cm ³ ) and more.

 This object is achieved by the fact that in the quick-connect connector for pneumatic or hydraulic actuators containing a housing, a spring, a stopper button and an adapter telescopically sealed to the housing, the adapter has at least one protrusion, and the housing has an appropriate number of ledges, the stopper button is located in the button socket of the case and, preloaded by the spring, locks the adapter, which, when the stop button is pressed, has the ability to turn in any direction until it engages or disengages its protrusions with ledges corps.

 The invention is illustrated in the drawings.

 FIG. 8 is a sectional view of a connector with a coil spring along the locking plane of the adapter.

 FIG. 9 is a plan view of a connector housing with a coil spring.

 The connector consists of a housing 1, a spring 2, a stop button 3, an o-ring 4, an adapter 5. The adapter 5 has at least one protrusion 6 with a slot 7 and a neck 8, and on the housing 1 there are ledges 9 and adjusting jaws 10 corresponding to the number protrusions 6 on the adapter 5, and the width of the pharynx 10 is larger than the width of the protrusion 6, and the button socket 11 under one of the ledges 9.

 The adapter 5 through the pharynx 10 is telescopically mounted with the neck 8 in the opening of the housing with the sealing ring 4. The protrusions 6 of the adapter 5 are engaged with the ledges 9 of the housing 1 by turning the adapter in any direction when the stopper button 3 is pressed, and when the slot 7 is combined with the button socket 11 the adapter 5 is locked by the stopper button 3, which is pressed by the spring 2.

 To disconnect the connector, it is necessary to press the stop button 3, turn the adapter 5 in any direction until the tabs 6 of the adapter 5 with the ledges 9 of the housing 1 are disengaged and the adapter is removed from the connection with the housing 1 (Fig. 4).

This connector provides the ability to connect instruments, assemblies and mechanisms to pneumatic and hydraulic conductors with a working pressure of up to 10 MPa (100 kgf / cm ² ) or more. The connector is easy to operate, does not require much effort and an additional tool for performing operations - “connection” or “disconnection” due to the small stiffness of the spring, which creates an effort only to hold the stop button.

 There are no parts in the connector that are interconnected by press fit. The connector, depending on the required flow rate of the working fluid (gas, liquid), in order to reduce the overall dimensions, can be made with a leaf (Fig. 1) or screw (Fig. 7) spring. The degree of tightness of the connection is determined by the tolerances on the dimensions of the neck of the adapter, the holes of the housing and the diameters of the o-ring (O-rings, rubber, round section for hydraulic and pneumatic devices. Design and dimensions. GOST 9833-73).
