Embodiment

Shown in referring to Fig.1~Fig. 2, the utility model discloses a kind of unenhanced level framves of quick self modulation, including shell 1, guarantor Shield 2 and support leg 3.

Above-mentioned shell 1 is spherical shell, bottom flat, upper opening.

Two battle pins 40 are oppositely arranged on the inner wall of 1 opening of above-mentioned shell.Annulus 41 is provided on battle pin 40.Annulus 41 Periphery wall on be oppositely arranged two annular distances 42.Battle pin 40 is inserted into annular distance 42, enables annulus 41 with the central shaft of battle pin 40 It is rotated freely centered on line.Annulus 41 can also be two a quarter rings, and battle pin 41 and annular distance 42 are separately positioned on its both ends.

The internal perisporium of above-mentioned annulus 41 is oppositely arranged two platform pins 43, and the central axis of center axis and battle pin 40 hangs down Directly.It is provided with table top 44 on platform pin 43, offers platform hole on table top 44, in 43 insert stand hole of platform pin, enables table top 44 with platform It is rotated freely centered on the central axis of pin 43.Table top 44 can be regular shape, can also be irregular shape.40 He of battle pin The intersection point of platform pin 43 overlapped with the center of gravity of table top 44 or positioned at table top 44 center of gravity on the extended line of table top 44.

The upper surface of above-mentioned table top 44 is provided with fixed seat 45, is located at the center of table top 44.Fixed seat 45 is for solid Determine scanner 5.

The plane perpendicular of above-mentioned table top 44 is provided with plumbing bar 46, and diameter is less than opposite 2 points of the shortest distance of table top 44. The free end of plumbing bar 46 is provided with hypophysis 47, and shell 1 does not contact.The center of gravity of table top 44 and the center of gravity of hypophysis 47 are respectively positioned on vertical On the central axis of bar or the extended line of central axis.The gravity of hypophysis 47 is at a distance from the center of gravity to the center of gravity of hypophysis of table top 44 Product much larger than scanner 5 product of the gravity at a distance from the center of gravity to the center of gravity of hypophysis of table top 44.Hypophysis 47 can be Sphere coordinates with the shell 1 of spherical shell shape, can increase the deflection angle allowed.

Restricted bar 60 is arranged in the bottom of above-mentioned shell 1, is threaded through at the center of 1 bottom of shell.Limit the two of bar 60 End is respectively arranged with restriction plate 61 and handle 64, and restriction plate 61 is located inside shell 1, and handle 64 is located at outside shell 1.Restriction plate 61 be concave arc panel, and cambered surface radius is identical with the maximum radius of 47 movement locus of hypophysis, i.e. hypophysis 47 and its rotation center Maximum distance.It is provided with friction pad in the concaved circular cambered surface of restriction plate 61, towards hypophysis 47.Restriction plate 61 and shell 1 it is interior Spring 62 is provided between bottom surface, spring 62 is in compressive state.Spring 62 can be set on limitation bar 60.Handle 64 and shell The catch 63 being fixed on limitation bar 60 is provided between the outer bottom of body 1, catch 63 is so that spring 62 is pushing restriction plate 61 When moving upwards, the concaved circular cambered surface for making restriction plate 61 is overlapped with the largest motion track of hypophysis 47 just, so that shell 1 is askew Restriction plate 61 also can carry out good braking to hypophysis 47 when tiltedly.In use, handle 64 is pulled down, hypophysis 47 is i.e. towards vertical Direction rotates；The hypophysis 47 of release handle 64, swing stops because of the frictional force of restriction plate 61；Handle 64 is pulled down again, is hung down Body 47 continues towards vertical direction rotation；Repeating the above steps can be such that hypophysis 47 quickly stops in the vertical direction, at this time Release handle 64 can also fix hypophysis 47.

Above-mentioned protective cover 2 is arranged in the opening of shell 1, is spherical shell shape.It is uniformly provided in the circumferential wall of protective cover 2 4 light holes 20 are sector wide at the top and narrow at the bottom.Protective cover 2 can protect scanner 5 not to be damaged under complicated external environment Wound；Fan-shaped light hole 20 wide at the top and narrow at the bottom can ensure still there is good light extraction gap in the case that shell 1 is crooked.

The flat position in 1 bottom of shell is arranged in above-mentioned support leg 3, at least there are three.Support leg 3 being capable of adjusting angle Degree reduces the requirement to environment.

The foregoing description of the disclosed embodiments enables professional and technical personnel in the field to realize or use this practicality new Type.Various modifications to these embodiments will be apparent to those skilled in the art, and determine herein The General Principle of justice can be realized in other embodiments without departing from the spirit or scope of the present utility model.Cause This, the utility model is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein The widest range consistent with novel point.
