The utility model discloses a quick-connect plug pliers, which can quickly disassemble a quick-connect piece (not shown) of a civil water purifying device. The quick-connect plug pliers comprise a lower pliers handle 1 and an upper pliers handle 2 which are mutually hinged, and the upper pliers handle 2 can rotate relatively.

The front end of the lower forceps handle 1 is fixed with a lower forceps head 3. In the present embodiment, the lower clamp head 3 is integrally formed with the lower clamp handle 1. The lower jaw 3 is provided with a lower jaw 31 penetrating in the vertical direction. In a specific application, the lower jaw 31 is used for inserting the body of the quick plug-in.

The front end of the upper clamp handle 2 is provided with a rotatable unlocking pressing plate 4. The upper tong handle 2 is pressed downwards against the unlocking pressure plate 4 by a first pressure spring 61. As shown in the drawing, a first pressure spring 61 is located at the front end of a hinge shaft of the upper caliper handle 2 and the unlocking pressing plate 4. The first pressure spring 61 is arranged between the upper plier handle 2 and the unlocking pressure plate 4, and the first pressure spring 61 enables the outer end of the unlocking pressure plate 4 to lean against the lower plier head 3. In the present embodiment, the unlocking pressing plate 4 is provided with a groove 42, and the end of the first compression spring 61 is inserted into the groove 42.

The unlocking pressure plate 4 is provided with a receiving cavity 43, the bottom 431 of which is provided with a middle jaw 41. A lever member 5 extending into the receiving chamber 43 and rotatably connected to the unlocking pressure plate 4. As shown in the drawings, one end of the lever member 5 is inserted into the receiving chamber 43, and a portion thereof is exposed from the receiving chamber 43, and the portion exposed from the receiving chamber is adapted to be engaged with the front end of the upper jaw handle. The lever 5 is provided with an upper jaw 51 penetrating in the vertical direction, and the upper jaw 51, the middle jaw 41 and the lower jaw 31 correspond to each other. In this embodiment, the front end of the unlocking pressing plate 4 is used for pressing the inner ring plate of the quick plug-in unit, and when the inner ring plate is sunken inwards, the locking plate inside is unlocked, so that the quick plug-in unit is in a detachable state. The upper jaw 51 is used for inserting the water pipe on the quick plug-in unit, and the lever member 5 can clamp the water pipe.

When the upper plier handle 2 is forced to press the front end against the rear end of the lever member 5, the front end of the lever member 5 tilts away from the lower plier head 3, and when the upper plier handle 2 is not forced to press the front end against the bottom wall of the receiving cavity 43. In this embodiment, a structure of the second pressure spring 62 is further adopted, one end of the second pressure spring 62 abuts against the rear end of the lever member 5, and the other end of the second pressure spring 62 abuts against the unlocking pressure plate 4. By providing the structure of the second pressure spring 62, the front end of the lever member 5 can be made to abut against the bottom wall of the receiving chamber 43. Normally, the front end of the lever 5 is always kept in contact with the bottom wall of the receiving chamber 43.

In the description of the present application, the constant holding means a state in which the related art feature is in when no external force is applied to the quick connect plug holder, and this state is releasable.

When specifically using, the body of fast plug-in components injects under in the jaw 31, unblock clamp plate 4 is along injecting on the interior crown plate of fast plug-in components, then hold the rear end of last pincers handle 2 and lower pincers handle 1 hard, make the binding clip, binding clip 3 acts on in opposite directions down, it first acts on first pressure spring 61 to go up the binding clip, first pressure spring 61 transmits the decurrent pressure of last binding clip for unblock clamp plate 4, unblock clamp plate 4 makes the front end of unblock clamp plate 4 compress tightly the interior crown plate of fast plug-in components under the effect of the pressure of first pressure spring 61, the interior crown plate invagination, its inside locking plate unblock. The rear end of the lever member 5 is also pressed down by the upper tong head, the front end of the lever member 5 clamps the water pipe which is spliced with the quick plug-in unit, the front end of the lever member 5 starts to move upwards, and the water pipe is pulled out from the quick plug-in unit.

In the present embodiment, the force of the first compression spring 61 against spring deformation is larger than the force of the second compression spring 62 against spring deformation.

In this embodiment, the rear end of the lever 5 is always separated from the front end of the upper jaw lever 2. In a specific application, when the inner ring plate of the quick plug-in unit is pressed to the bottom, the first compression spring 61 starts to contract under the action of the upper tong head pressure. The upper tong head is pressed down continuously to contact the rear end of the lever component. The contraction pressure of the second pressure spring 62 is smaller than the pressure of the upper tong head, the rear end of the lever component is pressed downwards, and the front end of the lever component starts to move upwards, so that two-stage work is formed.

In the description of the present application, the constant disconnection means a state in which the related art feature is in a state where no external force is applied to the quick connect plug jaws, and this state is releasable.

When no external force is applied to the upper clamp handle 2, the lever member 5 is inclined relative to the unlocking pressing plate 4. By adopting such a structure, the water pipe can be more easily pulled out.

In this embodiment, the lever member 5 includes a left rod 501 and a right rod 502, the left rod 501 and the right rod 502 are in a split structure, and the left rod 501 and the right rod 502 are both hinged to the unlocking pressing plate 4, the left rod 501 and/or the right rod 502 are movable in the direction of the hinge shaft thereof, the left rod 501 and the right rod 502 are disposed oppositely, and a space is formed between the left rod 501 and the right rod 502, the receiving cavity 43 is wide at the bottom and narrow at the top, and the left rod 501 and the right rod 502 contact the side wall 432 of the receiving cavity to reduce the space in the tilting process of the front end of the lever member 5. In this embodiment, the inside of the unlocking pressing plate 4 is a trapezoidal cavity, which has a narrow top and a wide bottom, and the lever component moves upward, during which the lever component is acted by the side wall of the unlocking pressing plate 4 to make the left rod 501 and the right rod 502 close to each other, so as to clamp the water pipe inserted into the quick plug-in unit. As another embodiment of the lever member 5, the left rod 501 and/or the right rod 502 may adopt an elastic deformation structure, which is elastically deformed when receiving a force of unlocking the side wall of the pressing plate 4, so that the distance between the left rod 501 and the right rod 502 can be changed.

In this embodiment, the lower jaw 31 is wider at the front and narrower at the back. The middle jaw 41 is wide in front and narrow in back. The upper jaw 51 is wide in front and narrow in back so as to adapt to quick inserts of different specifications. Typically, the lower jaw 31, the middle jaw 41, the upper jaw 51, etc. are large.

The above-mentioned embodiment is only the preferred embodiment of the present invention, and does not limit the protection scope of the present invention according to this, so: all equivalent changes made according to the structure, shape and principle of the utility model should be covered within the protection scope of the utility model.
