Technical Field
The utility model relates to a dustproof quick-operation joint.
Background
The existing button type quick coupling is mainly used for quick connection between pipelines. The button type quick connector can be controlled to be connected with and disconnected from an external conduction pipe through a button lock on the button type quick connector, and has the advantages of being simple to operate and rapid to disassemble and assemble, so that the button type quick connector is widely applied to pressure detection of a pneumatic system and a hydraulic system. The button type quick connector is provided with a mounting hole and a movable button lock mounted in the mounting hole, and due to the fact that a certain gap is reserved between the button lock and the wall of the mounting hole, external dust easily enters the interior of the connector through the gap, and the connector is damaged.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a dustproof quick-operation joint, its is rational in infrastructure, and has dustproof function, is favorable to prolonging quick-operation joint's life.
In order to achieve the purpose, the technical scheme of the utility model is to design a dustproof quick joint, which comprises a joint connecting part, a joint body connected with the joint connecting part, and a button lock arranged on the joint body;
a fluid channel is arranged in the connector connecting part, one end of the connector connecting part extends to the inner cavity of the connector body, a valve seat with an inner hole is arranged at the end part of the connector connecting part, a valve core is connected in the inner hole of the valve seat in a sliding manner, and a valve core reset spring fixedly connected with the valve core is arranged in the fluid channel;
the outer wall of the joint body is provided with a mounting hole, the axis of the mounting hole is perpendicular to the axis of the joint body, the mounting hole is communicated with the inner cavity of the joint body, the button lock comprises a button body and a locking portion, the button body is arranged in the mounting hole, the locking portion is integrally connected to the bottom of the button body, the locking portion extends to the inner cavity of the joint body, a button reset spring is connected between the bottom of the locking portion and the inner wall of the joint body, the locking portion is provided with a through hole for an external pipe fitting to pass through, a raised arc-shaped fixture block is arranged at the bottom of the through hole, an annular dust-proof groove is formed in the outer wall of the button body, a dust-proof ring is arranged in the annular dust-proof groove, and the dust-proof ring abuts against the inner wall of the mounting hole.
Preferably, the dustproof slot is arranged close to the bottom of the button body.
The utility model has the advantages and the beneficial effects that: the dustproof quick connector is reasonable in structure, has a dustproof function, and is beneficial to prolonging the service life of the quick connector.
During the use, the arc fixture block that sets up in the locking portion through-hole is used for the joint fixed with the outside pipe fitting of connecting this body coupling to the accessible is pressed the button body and is relieved the locking to outside pipe fitting. Because leave certain clearance between the pore wall of button body and mounting hole, the dust is inside through this clearance entering joint body very easily, lead to causing the damage to quick-operation joint, quick-operation joint's life has seriously been influenced, consequently, set up annular dust-proof groove on the outer wall of button body, and set up the dust ring that supports in the mounting hole inner wall in annular dust-proof groove, it is inside through the clearance entering joint body between button body and the mounting hole to block outside dust by the dust ring, thereby be favorable to prolonging quick-operation joint's life.
Drawings
Fig. 1 is a schematic diagram of the present invention.
Detailed Description
The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
The utility model discloses the technical scheme who specifically implements is:
as shown in fig. 1, a dust-proof quick coupling includes a coupling member 1, a coupling body 2 coupled to the coupling member 1, and a push button lock installed at the coupling body 2;
a fluid channel 3 is arranged in the connector connecting part 1, one end of the connector connecting part 1 extends to an inner cavity of the connector body 2, a valve seat 4 with an inner hole is arranged at the end part of the connector connecting part 1, a valve core 5 is connected in the inner hole of the valve seat 4 in a sliding manner, and a valve core reset spring 6 fixedly connected with the valve core 5 is arranged in the fluid channel 3;
the outer wall of the connector body 2 is provided with a mounting hole, the axis of the mounting hole is perpendicular to the axis of the connector body 2, the mounting hole is communicated with an inner cavity of the connector body 2, the button lock comprises a button body 7 and a locking portion 8, the button body 7 is arranged in the mounting hole, the locking portion 8 is integrally connected to the bottom of the button body 7, the locking portion 8 extends to the inner cavity of the connector body 2, a button reset spring 9 is connected between the bottom of the locking portion 8 and the inner wall of the connector body 2, the locking portion 8 is provided with a through hole for an external pipe fitting to pass through, the bottom of the through hole is provided with a convex arc-shaped fixture block 10, the outer wall of the button body 7 is provided with an annular dust-proof groove, a dust-proof ring 11 is arranged in the annular dust-proof groove, and the dust-proof ring 11 supports against the inner wall of the mounting hole.
