Detailed description of the invention
In order to make those skilled in the art be more fully understood that technical scheme, it is described in further detail with embodiment below in conjunction with the accompanying drawings.
The structure of the embodiment of lamp casing of the present invention and Varied clearance hinge is as shown in Figure 1, Figure 2 and Figure 3, figure includes 3, two back-moving springs of 2, two axis pin bases of 1, two positioning sleeves of two bearing pins, 5, hinge seat 6 of 4, two spring cappings, and upper casing 7 and lower casing 8.
In figure, Varied clearance hinge is by hinged to upper casing 7 and the lower casing 8 of lamp casing.Hinge seat 6 and the lower casing 8 of Varied clearance hinge are connected as a single entity, and hinge seat 6 is positioned at the middle part of side, lower casing 8 edge；The axis pin base 3 of Varied clearance hinge and upper casing are connected as a single entity, and axis pin base 3 is positioned at the two ends of upper casing 7 edge correspondence hinge seat 6.
The concrete structure of Varied clearance hinge is as follows.
Two axis pin bases 3, through axis pin base 3, are hinged on the two ends of hinge seat 6 by bearing pin 1.Bearing pin 1 is axially movable relative to axis pin base 3 and hinge seat 6, is provided with the detent mechanism that bearing pin 1 moves between bearing pin 1 and axis pin base 3.
Bearing pin 1 is provided with external screw thread 11 away from a section of hinge seat 6, and footpath, the externally threaded end is more than the diameter of optical axis, and the end of bearing pin 1 thread segment is provided with knob 12, for transmitting pulling force and the torsion that user manual operation produces.
The critical component of detent mechanism is the positioning sleeve 2 being arranged between bearing pin 1 and axis pin base 3, and the endoporus of positioning sleeve 2 is provided with female thread, and positioning sleeve 2 rotation set is on the external screw thread 11 of bearing pin 1.
Positioning sleeve 2 is provided with, away from the end of hinge seat 6, the semi-circular step 21 coordinated with axis pin base 3 end；The end of axis pin base 3 is provided with the semi-circular boss 31 corresponding with semi-circular step 21.Bearing pin 1 towards hinge seat 6 move axially time, semi-circular step 21 and semi-circular boss 31 are symmetrical in opposite directions also to be positioned；When bearing pin 1 away from hinge seat 6 moves axially, semi-circular step 21 can overlap with semi-circular boss 31 and position.
The centre at semi-circular boss 31 top of axis pin base 3 end is provided with lock tab 32；The centre of the semi-circular step 21 of positioning sleeve 2 is provided with the latch recess 22 matched with lock tab 32.When semi-circular step 21 and semi-circular boss 31 overlap, lock tab 32 enters latch recess 22.
Axis pin base 3 is built-in with back-moving spring 4, and back-moving spring 4 is set on positioning sleeve 2.The afterbody of positioning sleeve 2 is provided with spring capping 5, and the female thread of spring capping 5 is tightened on the external screw thread 23 of positioning sleeve 2 afterbody fixing connection.
When pulling the knob of bearing pin 1 end, positioning sleeve 2, spring capping 5 make moving axially of away from hinge seat 6 relative to axis pin base 3 together with bearing pin 1, and back-moving spring 5 is compressed.When the upper plane of the lock tab 32 that the lower plane of the semi-circular step 21 of positioning sleeve 2 end is higher than on axis pin base 3 end semi-circular boss 31, if turning knob 180 degree, latch recess 22 on semi-circular step 21 can be alignd with lock tab 32, at this moment knob is decontroled, lock tab 32 enters latch recess 22, and semi-circular step 21 overlaps with semi-circular boss 31.As shown in Figure 4, Figure 5.
Again pull the knob of bearing pin 1 thread head, and decontrol after rotating 180 degree, under the effect of back-moving spring 5, positioning sleeve 2, spring capping 5 make moving axially towards hinge seat 6 relative to axis pin base 3 together with bearing pin 1, back-moving spring 5 is released, and semi-circular step 21 and semi-circular boss 31 are symmetrical in opposite directions and position.
The inward at both ends of hinge seat 6 is provided with and coordinates reducing hole with bearing pin 1, and two reducing holes are coaxial.Reducing hole is divided into macropore section 61, taper hole section 62 and aperture section 63.After bearing pin 1 moves axially towards hinge seat 6, the bearing pin 1 macropore section 61 through reducing hole and taper hole section 62 enter aperture section 63, and bearing pin 1 is less with the fit clearance of aperture section 63.After bearing pin 1 away from hinge seat 6 moves axially, bearing pin 1 exits the aperture section 63 in reducing hole, returns to macropore section 61 by taper hole section 62, and bearing pin 1 is bigger with the fit clearance of macropore section 61.
The assembling process of the embodiment of the present invention.
The most first being assembled to by positioning sleeve 2 in the axis pin base 3 linked together with upper casing 7, the semi-circular step 21 of positioning sleeve 2 end assembled is symmetrical in opposite directions with the semi-circular boss 31 of axis pin base 3 end to be coordinated.
2. back-moving spring 4 is assembled in the cavity between positioning sleeve 2 and axis pin base 3, uses spring capping 5 to be screwed on the external screw thread of positioning sleeve 2 afterbody fixing, back-moving spring 4 is covered.
3., after two axis pin bases 3 of upper casing 7 all install, the hinge seat 6 linked together by lower casing 8 is placed between two axis pin bases 3, is screwed in positioning sleeve 2 by bearing pin 1, to revolve motionless.Just complete the assembling process of lamp casing.
The using method of the embodiment of the present invention.
1., after the upper casing of light fixture and lower casing are built, the semi-circular step 21 of positioning sleeve 2 end is just symmetrical in opposite directions with the semi-circular boss 31 of axis pin base 3 end to be coordinated, and is aligned in approximately the same plane.Bearing pin 1 is inserted into the aperture section 63 in hinge seat 6 reducing hole, and the aperture size of aperture section 63 is slightly larger than the external diameter of bearing pin 1, and bearing pin 1 just coordinates for small-gap suture with hinge seat 6, gap about about 0.1mm.
2. when light fixture parts to be changed need to open upper casing 7, being pulled up by bearing pin 1 with hands, bearing pin 1 drives positioning sleeve 2 to move axially together.When the upper plane of the lock tab 32 that the lower plane of the semi-circular step 21 of positioning sleeve 2 is higher than on axis pin base 3 semi-circular boss 31, rotating pin 1.After rotating 180 degree, being fallen by bearing pin 1, the lock tab 32 on semi-circular boss 31 just enters in the latch recess 22 on semi-circular step 21.Between bearing pin 1 with positioning sleeve 2 relative motionless, at this moment the bearing pin 1 aperture section 63 from the reducing hole of hinge seat 6 is extracted out and is returned in macropore section 61, and bearing pin 1 increases with the fit clearance of hinge seat 6, the most just can rotate upper casing 7 or the lower casing 8 of light fixture, and articulate is flexible.
3. after lower casing 8 and upper casing 7 close, bearing pin 1 is driven positioning sleeve 2 pull-up, rotate 180 degree, bearing pin 1 passes through the elastic reset of back-moving spring 4 to initial position with positioning sleeve 2, bearing pin 1 is inserted into the aperture section 63 in reducing hole by the taper hole section 62 in hinge seat 6 reducing hole, pull the adjustment of relative position between lower casing 8 with upper casing 7, it is achieved lower casing 8 is accurately positioned with upper casing 7.
Foregoing, only presently preferred embodiments of the present invention, not carry out scope restriction to the present invention.Those skilled in the art, according to the central scope of the present invention and spirit, can carry out corresponding flexible or amendment very easily.As hinge seat can arrange the straight hole coordinated with bearing pin, bearing pin is provided with the multidiameter shaft that the straight hole with hinge seat coordinates, and by the different-diameter section of multidiameter shaft and coordinating of hinge seat, reaches the Variable between bearing pin and hinge seat.Therefore protection scope of the present invention should be as the criterion with the covering scope of claim.
