Description
Technical field
This utility model relates to a kind of piano field, particularly relates to a kind of Height Adjustable caster of piano.
Background technology
The caster for piano of prior art includes wheel, support, central shaft and socket axle sleeve on center shaft, wheel turns is connected on support, the lower end of central shaft is affixed with support, it is provided with a ball between upper end and the axle sleeve of central shaft, central shaft is rolled by ball and is rotatably assorted with axle sleeve, there is following defect in the caster for piano of said structure during actual use: rolls in axle sleeve owing to existing castor only relies on a ball, in piano frame moving process, ball is easy to deviate pre-centering position and cause ball stuck at axle sleeve and central shaft under the effect of piano frame gravity, thus cause the inconvenience that piano moves, and existing castor can not adjust height, when ground out-of-flatness, then need the height by adjusting different castor, so that piano is horizontal.
Summary of the invention
For solving above-mentioned technical problem, the purpose of this utility model is to provide a kind of simple in construction, Height Adjustable caster of piano easy to use.
For achieving the above object, this utility model is by the following technical solutions:
A kind of Height Adjustable caster of piano, including fixing seat, axostylus axostyle, roller and caster mount, the axis of described fixing seat is provided with centre bore, and the upper end of axostylus axostyle is located in this centre bore, and described roller is rotationally connected with on caster mount；The lower end of described axostylus axostyle is rotationally connected with the top of caster mount, the upper end edge of described axostylus axostyle its be axially arranged with at least one smooth restriction face, the bottom part ring of described fixing seat is provided with downwardly convex boss around axostylus axostyle, the side of this boss is provided with the screwed hole being through to fixing seat centre bore, connecting in this screwed hole and have adjustment screw, the root adjusting screw relies on the restriction face of axostylus axostyle to be fixed in the centre bore of fixing seat the upper end of axostylus axostyle.
The lower end of described axostylus axostyle is provided with bulge loop, and the bottom of axostylus axostyle is through the through hole at caster mount top, and bulge loop relies on the upper surface of through hole, and on the bottom of axostylus axostyle, connection has nut.
The lower surface of described bulge loop is provided with annular lubricant groove, is provided with lubricant grease in annular lubricant groove.
The restriction face of described axostylus axostyle is provided with the hole, location that a more than row is arranged from top to bottom, and described adjustment screw root relies in hole, location.
This utility model uses above technical scheme, has the advantage that caster of piano of the present utility model eliminates the design of ball, it is to avoid the phenomenon that ball is stuck, thus ensure that the convenience that piano moves.It addition, use adjustment screw to adjust the height of castor, structure is simpler, adjusts convenient.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, this utility model is described in further details；
Fig. 1 is the generalized section of a kind of Height Adjustable caster of piano of this utility model；
Fig. 2 is the cross sectional representation of axostylus axostyle.
Detailed description of the invention
As shown in Figure 1 or 2, this utility model includes that fixing seat 1, axostylus axostyle 2, roller 3 and caster mount 4, the axis of fixing seat 1 are provided with centre bore 11, and the upper end of axostylus axostyle 2 is located in this centre bore 11, and roller 3 is rotationally connected with on caster mount 4；The lower end of axostylus axostyle 2 is rotationally connected with the top of caster mount 4, the upper end edge of axostylus axostyle 2 its be axially arranged with at least one smooth restriction face 21, the bottom part ring of fixing seat 1 is provided with downwardly convex boss 12 around axostylus axostyle 2, the side of this boss 12 is provided with the screwed hole being through to fixing seat 1 centre bore 11, connecting in this screwed hole and have adjustment screw 5, the root of adjustment screw 5 relies on and is fixed in the centre bore 11 of fixing seat 1 with the upper end by axostylus axostyle 2 on the restriction face 21 of axostylus axostyle 2.
The lower end of axostylus axostyle 2 is provided with bulge loop 22, and the bottom of axostylus axostyle 2 is through the through hole at caster mount 4 top, and bulge loop 22 relies on the upper surface of through hole, and on the bottom of axostylus axostyle 2, connection has nut 6.The lower surface of bulge loop 22 is provided with annular lubricant groove, is provided with lubricant grease 7 in annular lubricant groove.Pass through said structure, it is possible to achieve relatively rotating between caster mount 4 and axostylus axostyle 2, and the design of lubricant grease 7 can reduce friction, is moved easily piano.
The restriction face 21 of axostylus axostyle 2 is provided with the hole, location 23 that a more than row is arranged from top to bottom, adjusts screw 5 root and relies in hole 23, location, such structure can effectively fixed axostyle 2 and limit the relative motion between axostylus axostyle 2 and fixing seat 1.
When needing the height adjusting castor, unclamp adjustment screw 5, then adjust the height and position of axostylus axostyle 2 so that the root adjusting screw 5 leans to corresponding hole, location 23, adjust screw 5 finally by locking, thus realize lifting the bearing height of piano.
