The utility model discloses simple structure, convenient operation, it is can be planar 360 rotatory, solve the problem that receives angle and position constraint in the tube coupling, reduce the cost, improvement work efficiency.
Description
Technical field
The utility model relates to aeronautic measurement equipment technical field, is specifically related to a kind of chicksan for avigation piece.
Background technique
Electro-hydraulic servo actuator, English: Electro-hydraulicservoforactuator, be a hydraulic actuator, the hydraulic energy from hydraulic power can be converted to mechanical energy, the displacement transducer that also can be carried by product as required or position limit switch carry out servocontrol.For performing the order of master controller, the speed of control load, direction, displacement, power, feed back to master controller signal High power output simultaneously, and running position is accurate, the features such as volume is little.
In Aviation Industry, in actuator hydraulic pressure test in the past, adopt the Placement of straight joint and bend pipe, by the restriction of angle and position, pipeline connects complicated.
Therefore need to adopt a kind of new swivel joint, make them can planar 360 ° of rotation, solve during pipeline connects the problem being subject to angle and position limitation.
Summary of the invention
The purpose of this utility model is for above-mentioned Problems existing, provides a kind of structure simple, easy to operate, can planar 360 ° of rotation, solve pipeline connect in by the problem of angle and position limitation, minimizing cost, the chicksan of increasing work efficiency.
The purpose of this utility model realizes being made up of following aspect:
Chicksan, is characterized in that: include a wresting-in type joint, and wresting-in type joint is that mid diameter is little, the structure that two diameter is large, and having a sleeve pipe in middle cover, one end of sleeve pipe is compressed by nut, and nut is arranged on the central shaft of wresting-in type joint; Described sleeve pipe is fixedly connected with a swivel joint, swivel joint can rotate around wresting-in type joint axis with sleeve pipe, and is connected with wresting-in type joint.
In such scheme, the contact position between described sleeve pipe and wresting-in type joint is provided with two pairs of rubber rings, and its inner ring is seal ring, and outer ring is guard circle, is also provided with packing ring between sleeve pipe and nut.
In such scheme, described sleeve pipe has hole, the center hole of hole and wresting-in type joint connects, and docks with swivel joint.
In such scheme, the axis of described swivel joint and the axes normal of wresting-in type joint.
The beneficial effects of the utility model are:
The utility model structure is simple, easy to operate, can planar 360 ° of rotation, solve pipeline connect in by the problem of angle and position limitation, minimizing cost, increases work efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model example structure plan view;
In figure 1, wresting-in type joint, 2 nuts, 3 packing rings, 4 swivel joints, 5 sleeve pipes, 6 seal rings, 7 guard circles.
Embodiment
For better understanding skill Design Technology of the present utility model, be described below in conjunction with drawings and Examples.Following examples describe and are only exemplary and explanatory, do not have any restriction to the utility model protection domain.
Chicksan as shown in Figure 1, includes a wresting-in type joint 1, and wresting-in type joint 1 is that mid diameter is little, the structure that two diameter is large, and having a sleeve pipe 5 in middle cover, one end of sleeve pipe 5 is compressed by nut 2, and nut 2 is arranged on the central shaft of wresting-in type joint 1; Described sleeve pipe 5 is fixedly connected with a swivel joint 4, swivel joint 4 can rotate around wresting-in type joint 1 axis with sleeve pipe 5, and is connected with wresting-in type joint 1.
In the present embodiment, the contact position between described sleeve pipe 5 and wresting-in type joint 1 is provided with two pairs of rubber rings, and its inner ring is seal ring 6, and outer ring is guard circle 7, is also provided with packing ring 3 between sleeve pipe 5 and nut 2.
In the present embodiment, described sleeve pipe 5 has hole, and the center hole of hole and wresting-in type joint 1 connects, and docks with swivel joint 4.
In the present embodiment, the axis of described swivel joint 4 and the axes normal of wresting-in type joint 1.
Wresting-in type joint 1 is connected in actuator; swivel joint 4 can complete and the docking of pipeline on 360 ° of any directions; owing to have employed guard circle 7; make the working pressure of whole swivel joint rise to 31.5MPa, the test requirements document of the various hydraulic actuator of current Boeing and Airbus series can be met.
Protection domain of the present utility model is not limited to the above embodiments, and obviously, those skilled in the art can carry out various change and distortion to the utility model and not depart from scope and spirit of the present utility model.If these are changed and distortion belongs in the scope of the utility model claim and equivalent technologies thereof, then intention of the present utility model also comprises these changes and distortion.
