Abstract
The utility model relates to a kind of universal hinge, particularly a kind of spherical universal hinged connecting device.In the static test Fixture Design stage, the steel plate design work controlling line of force direction can be omitted.Select this device with versatility.At test tool erection stage, according to the demand in line of force direction in test, first ball rod (1) is packed into No. 1 sleeve (2) and be connected completely with force application device afterwards.Adjust the opening direction of No. 1 sleeve (2), the direction of rotating sphere head rod (1), obtain the line of force direction needed.Secondly No. 2 sleeves (3) and No. 1 sleeve (2) are threaded connection, finally No. 2 sleeves (3) are connected with fixing device, the force direction realizing needing controls.
Description
Technical field
The utility model relates to a kind of universal hinge, particularly a kind of spherical universal hinged connecting device.
Background technique
In static test, masterpiece is needed to be used in specific direction, present stage, usually can realize this purpose by the steel plate welding different amount.Different tests, the direction of power effect is different, so just need to manufacture corresponding controlling party to steel plate, and steel plates of these welding do not possess reusing, waste time and energy, add manufacture cost, extend the test period, cause waste.
Summary of the invention
The purpose of this utility model: provide a kind of structure simple, can be hinged mode the universal of multi-angle control.
Technical solutions of the utility model are: described connection set comprises ball rod 1, No. 1 sleeve 2 and No. 2 sleeves 3, the bulb of ball rod 1 is positioned at No. 1 sleeve, the opening diameter of No. 1 this end of sleeve 2 is greater than the diameter in ball rod 1 bar portion, be less than the diameter of bulb, the other end of No. 1 sleeve 2 has internal thread, one end of No. 2 sleeves 3 has ball-and-socket 4, and No. 2 sleeves 3 are fixed in No. 1 sleeve 2 by screw-thread fit, and the bulb of ball rod 1 is positioned at ball-and-socket 4.
One as the technical program is improved, and on the sidewall of one end that No. 1 sleeve 2 contacts with ball rod 1 bar portion, has width and is greater than the opening 5 that bar portion diameter is less than bulb diameter.
The beneficial effect of the technical program: in the static test Fixture Design stage, can omit the steel plate design work controlling line of force direction.Select this device with versatility.At test tool erection stage, according to the demand in line of force direction in test, be connected completely with force application device after first ball rod 1 being packed into No. 1 sleeve 2.The opening direction of adjustment No. 1 sleeve 2, the direction of rotating sphere head rod 1, obtains the line of force direction needed.Secondly No. 2 sleeves 3 and No. 1 sleeve 2 are threaded connection, finally No. 2 sleeves 3 are connected with fixing device.The force direction realizing needing controls.
Accompanying drawing explanation
Fig. 1 is structural scheme of mechanism of the present utility model;
Fig. 2 is No. 2 tube-in-tube structure schematic diagram;
In figure: 1 is ball rod, 2 is No. 1 sleeve, and 3 is No. 2 sleeves, and 4 is ball-and-socket, and 5 is opening.
Embodiment
Below in conjunction with accompanying drawing, the technical program is described in further detail.
Ball rod 1 one end is cylindrical body, is connected with force application device by screw thread, and the other end is spheroid, and spheroid is sleeved in No. 1 sleeve 2.No. 1 sleeve 2 is hollow cylinder, and No. 1 sleeve two ends internal diameter is different, ensures that ball rod cylinder physical efficiency is passed and do not pass.There is internal thread one end that No. 1 sleeve 2 internal diameter is large, No. 1 sleeve 2 is in the little one end open 5 of internal diameter, the width of opening is greater than ball rod cylinder diameter, is less than ball rod spheroid diameter, ensures that the spheric end of the cylinder physical efficiency precession of ball rod 1 and ball rod can not precession.No. 2 sleeve 3 one end are cylindrical body, are connected with fixing device by screw thread, and the other end is ball-and-socket 4.Ball-and-socket 4 is a hemisphere, and the spheroid of the diametric fit ball rod 1 of spheroid is made, and ensures that spherical physical efficiency is enclosed within ball-and-socket, contacts with ball-and-socket face.
In use, be connected completely with force application device after first ball rod 1 being packed into No. 1 sleeve 2.The opening direction of adjustment No. 1 sleeve 2, the direction of rotating sphere head rod 1, obtains the line of force direction needed.Secondly No. 2 sleeves 3 and No. 1 sleeve 2 are threaded connection, finally No. 2 sleeves 3 are connected with fixing device.
Claims (2)
