Abstract
The utility model relates to a universal air inlet joint for a pneumatic tool, which mainly comprises a hollow air inlet screw, a first sealing ring, a second sealing ring, a universal head, a screw sleeve, and an air inlet joint. The front end of the universal head is sheathed in the screw sleeve which is spirally connected with the rear end of the air inlet screw; the tail end of the universal head is exposed out of the screw sleeve and is spirally connected with the air inlet joint; a first and a second sealing sleeves are respectively arranged between the front end of the universal head and the tail end of the air inlet screw and between the tail end of the universal head and the air inlet joint; one end of the air inlet screw is arranged in a pneumatic tool body, and the air inlet joint is combined with an air pressure pipe. Through making use of multi-angle steering functions of the universal head in the screw sleeve, the air pressure pipe is caused to not to form obstruction to operation of the pneumatic tool, and the operation is convenient.
Description
The utility model relates to a kind of pneumatic tool, relates to or rather a kind of gas be introduced joint in the pneumatic tool from pneumatic tube.
Pneumatic tool A shown in the accompanying drawing 1, gas drives in pneumatic tube A1 enters pneumatic tool A, to improve operating efficiency.Yet pneumatic tool A now is at the place, body bottom of pneumatic tool A one joint A2 to be set in order to combine with pneumatic tube A1, and the front end of this joint A2 is screwed together in the pneumatic tool A, and tail end is exposed to the pneumatic tool A outside, is used in conjunction with pneumatic tube A1.The shortcoming that this combination came out is: because the joint A2 of conventional construction is a single structure body, front end is screwed together in the pneumatic tool A, in the time will using pneumatic tool A, need combine pneumatic tube A1 with the rear end of joint A2 and both are for axially linking, some is exposed to the pneumatic tool A outside joint A2, pneumatic tube A1 is combined in the extension that is equivalent to the A2 structure after joint A2 goes up, the user is when operation pneumatic tool A, because of combining between joint A2 and pneumatic tube A1 do not have flexibility, so can hinder operation, making it can't sidesway, need pneumatic tube A1 to be staggered as the operator, avoid its winding, because pneumatic tool A self is relatively heavier through hand commonly used, add joint A2 and pneumatic tube A1 to the obstruction in operator's work, thereby cause working efficiency not high.
The purpose of this utility model is a kind of air tool universal air input joint of design, and pneumatic tool can be turned to when operation flexibly, brings obstruction can for operator's operation, can by direction of operating pneumatic tube and hand be staggered at any time.
The purpose of this utility model is achieved in that a kind of air tool universal air input joint, one end is arranged in the pneumatic tool body, the other end is characterized in that in conjunction with pneumatic tube: the air inlet screw, first seal ring, second seal ring, Universal-head, swivel nut and the air input joint that comprise hollow; The Universal-head front end is set in the swivel nut, swivel nut and air inlet screw rear end are spirally connected, the Universal-head tail end is exposed to outside the swivel nut and with air input joint and is spirally connected, and described first, second stuffing box gland is separately positioned between Universal-head front end and air inlet screw tail end and between Universal-head tail end and air input joint; The air inlet screw is arranged in the described pneumatic tool body, and air input joint is in conjunction with described pneumatic tube.
Also include filter screen and jump ring, be arranged in the described air inlet screw front end.
The air tool universal air input joint of the utility model, air inlet screw with Universal-head is arranged in the air tool body, make universal joint can and the pneumatic tube of air inlet between be free angle and turn to, make the operator can freely rotate pneumatic tool, the pneumatic tube that can be attached thereto does not pin down.The air tool universal air input joint of the utility model, make combining between pneumatic tube, Universal-head and pneumatic tool body be beeline, the arm of force is the shortest, moment is minimum thereby the most laborsaving, and operator's application of force scope only relates to the pneumatic tool body, avoids being subjected to pullling of pneumatic tube.
Further specify technology of the present utility model below in conjunction with embodiment and accompanying drawing
Fig. 1 is the structural representation that pneumatic tool uses traditional jointing
Fig. 2 is the three-dimensional decomposition texture schematic representation of the universal air input joint of the utility model pneumatic tool
Fig. 3 is the three-dimensional schematic representation of the universal air input joint of the utility model pneumatic tool
Fig. 4 is the free angle go to action schematic representation of the universal air input joint of the utility model pneumatic tool
Fig. 5 is another embodiment's composite structure schematic representation of the universal air input joint of the utility model pneumatic tool
Addressed before Fig. 1 illustrates and repeated no more.
Also combination is referring to Fig. 3, Fig. 4 referring to Fig. 2, Fig. 3, and the universal air input joint 10 of pneumatic tool of the present utility model comprises air inlet screw 1, filter screen 2, jump ring 3, swivel nut 4, seal ring 5 and 7, Universal-head 6 and air input joint 8.One end is connected in the pneumatic tool A body, but the other end external gas pressure pipe A1.
During use, air inlet screw 1 front end spiral shell is located in the body of pneumatic tool A, pneumatic tube A1 then is connected with air input joint 8, make being connected between pneumatic tube A1, Universal-head 6 and pneumatic tool A body be beeline, when using operation pneumatic tool A to change its direction of operating, 6 of pneumatic tube A1 and Universal-heads can freely turn in the several angle scope, make pneumatic tube A1 can not produce skew because of the transformation of pneumatic tool A direction of operating, can avoid twining.And it is, the most laborsaving so the arm of force is the shortest, moment is minimum because being connected between pneumatic tube A1, Universal-head 6 and pneumatic tool A body is beeline.Operator's application of force scope only limits to the body of pneumatic tool A, avoids being subjected to pullling of pneumatic tube.Universal-head 6 is under the coating of swivel nut 4, and its steering angle is confined in the formed angular range of swivel nut 4 opening directions, so the operator can need not comprehend the position of pneumatic tube A1 fully when operation.
During enforcement, be connected with pneumatic tube A1 for making things convenient for air input joint 8, can adopt to be spirally connected, as the mode of structure of Fig. 2 to Fig. 4, also can adopt interlocking, inserted type as shown in Figure 5 connects.
In sum, the air tool universal air input joint of the utility model, but utilize the Universal-head of a various angle veer, its with pneumatic tool body bottom in combine and with after pneumatic tube combines, make and pneumatic tube between be various angle veer and use, so that operational convenience to be provided, can not be subjected to pining down of pneumatic tube.
