Abstract
The utility model relates to vertical piano trundles, which can be braked and locked and consist of wheels and a wheel carrier. The wheels are movably connected in the wheel carrier frame at the lower part of the wheel carrier; the wheels are provided with a wheel hole; the wheel carrier is provided with a wheel carrier hole corresponding to the wheel hole; and a butterfly lock bolt connects the wheel and the wheel carrier by the wheel holes and the wheel frame holes. The trundles for vertical piano provided by the utility model can rotate freely when the bolts are loosened and cannot move when the bolts are screwed up, which improve the stability of the piano.
Description
Technical field
The utility model relates to a kind of improvement of upright piano caster, particularly a kind of upright piano caster of energy braking and locking.
Background technology
Because upright piano is the musical instrument object that a kind of weight is heavier, volume is bigger, it moves fully by the slip of the castor that is installed in the piano bottom and is undertaken, because the device of brakeless locking on the existing upright piano caster, cause the upright piano poor stability, position after the placement very easily changes, and causes certain potential safety hazard.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of upright piano caster that solves the energy braking and locking of upright piano poor stability.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of upright piano caster of energy braking and locking, comprise wheel and wheel carrier, wheel is movably connected in the wheel frame-saw of wheel carrier bottom by wheel shaft, wheel is provided with the wheel hole, wheel carrier is provided with and takes turns corresponding wheel carrier hole, hole, and bolt is connected wheel and wheel carrier by the wheel hole with the wheel carrier hole, and bolt is a butterfly type clamping screw.
The upright piano caster that the utility model provides owing to connect wheel and wheel carrier with bolt, unclamps bolt wheel is freely rotated, even the wheel that tights a bolt can't move, has improved the stability of upright piano.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a structure left view of the present utility model.
Embodiment
As shown in Figure 1 and Figure 2, a kind of upright piano caster of energy braking and locking, comprise wheel 1 and wheel carrier 2, wheel 1 is movably connected in the wheel frame-saw 4 of wheel carrier 2 bottoms by wheel shaft 3, wheel 1 is provided with the wheel hole, wheel carrier 2 is provided with and takes turns corresponding wheel carrier hole, hole, and bolt 5 is connected wheel 1 and wheel carrier 2 by the wheel hole with the wheel carrier hole, and bolt 5 is a butterfly type clamping screw.
When the piano needs are mobile, unclamp butterfly type clamping screw 5, wheel 1 can freely rotate; When piano moves to assigned address, do not need to tighten butterfly type clamping screw 5 when mobile, fixedly wheel 1, it can't be moved get final product.
