Description
Technical field
The present invention relates to the field engineering of piano, specifically, relate to a kind of mounting structure and installation method of caster of piano, be particularly useful for transparent piano.
Background technology
Piano volume is large, Heavy Weight, when it is moved to use location, wishes that it can be parked in there stably and arbitrarily not move, therefore needs to install in the below of piano base a kind of conveniently moving, park reliable and stable universal caster wheel.
Authorization Notice No. is that the Chinese patent of CN 2218671Y discloses a kind of universal caster wheel for piano, and it is made up of vertical shaft, wheel disc, ball bearing of main shaft, support, the transverse axis being located at support both sides and the roller be arranged on transverse axis; Wheel disc is boss shape, its central authorities have vertical shaft hole, form the sliding shaft sleeve of vertical shaft, its corner has the mounting hole for being connected with piano base, ball bearing of main shaft is arranged between wheel disc and support, its upper and lower end face is fixedly connected with support with wheel disc respectively, and vertical shaft is fixedly connected with the top of support with the inner sleeve of ball bearing of main shaft through the vertical shaft hole of wheel disc.The universal caster wheel of this structure when mounted, piano base reserves jack, wheel disc inserts in jack from below, screw screws in piano base through the mounting hole of wheel disc, thus wheel disc is fixed on piano base, again vertical shaft and wheel disc are fixed as one, thus by universal caster wheel integral installation on piano base.
In order to make the assembling of universal caster wheel simpler, be everlasting on vertical shaft and offer circular groove, the stopper ring of band annular jaggy is set with in circular groove, the periphery of stopper ring protrudes from the outer wall of vertical shaft, due to the existence of breach, need to apply enough large axial force, vertical shaft hole inner wall extruding stopper ring, breach can diminish, and the external diameter of stopper ring also can diminish; Accordingly, ring-shaped depression position is also set in vertical shaft hole; When wheel disc and vertical shaft are installed, by force vertical shaft is knocked in wheel disc from below, make stopper ring enter ring-shaped depression position in vertical shaft hole.Vertical shaft is stuck in ring-shaped depression position by stopper ring, realizes the axial location of vertical shaft.
There is following shortcoming in existing structure: 1. needs many screws a universal caster wheel firmly could be fixed, mounting or dismounting inconvenience.2. there is a kind of transparent piano in high-end piano market, its shell makes of all-transparent material, such as imitative crystal material, organism glass etc., and the inner structure of piano is very clear, both can, piano as musical instrument, also piano can be carried out collecting and appreciating as an art work; If be applied on transparent qin by existing this mounting structure, through transparent piano base, can see wheel disc, be arranged in the vertical shaft of wheel disc and many screws, pole unsightly, have impact on the overall artistic effect of transparent piano.
Summary of the invention
For the technical matters existed in prior art, the object of the invention is: mounting structure and installation method that the caster of piano of simple, the easy for installation and good looking appearance of a kind of structure is provided.
In order to achieve the above object, the present invention adopts following technical scheme:
A mounting structure for caster of piano, comprises caster of piano; Caster of piano comprises vertical shaft and is enclosed within the wheel disc on vertical shaft; The mounting structure of caster of piano also comprises installing sleeve; Installing sleeve comprises sleeve part and is positioned at the axial limiting step of upper end, sleeve part, and wherein, the lower end of sleeve part is provided with internal thread hole; Piano base is provided with the jack run through, and installing sleeve inserts jack from top to bottom, and axial limiting step withstands piano base from top; The outer wall of wheel disc is provided with outside thread, and wheel disc screws in the internal thread hole of installing sleeve from the bottom up.After adopting this structure, to be spun fastening by the screw thread up and down of installing sleeve and wheel disc, the installation of caster of piano can be realized, on the one hand, wheel disc no longer needs screw to be fixed on caster of piano, saves threaded connector, easy for installation, free-hand or by simple Allen key can realize install; On the other hand, wheel disc and vertical shaft wrap up, when this structure is applied on transparent piano by installing sleeve, the outside column structure only seeing bright and clean installing sleeve, tailored appearance is generous, shows details, be conducive to the class promoting transparent piano, make it to become an art work worthy of the name; Moreover even if repeatedly carry, this mounting structure is also not easily loose, durable.
Coordinating between sleeve part with jack is free-running fit.After adopting this structure, be convenient to sleeve part and insert jack, also avoid sleeve part to support bad by jack simultaneously, damage piano base.
The outer wall of sleeve part is cylindric, and the cross-sectional plane of axial limiting step is rectangle.After adopting this structure, piano leg is equipped with at the position that the top of piano base is corresponding with axial limiting step, and axial limiting step is placed in the reserved shape in piano underfooting and caves in accordingly cavity volume, because axial limiting step is rectangle, without relatively rotating between axial limiting step and piano pin, wheel disc and installing sleeve are also without relatively rotating.
The material of installing sleeve is corrosion-resistant steel.After adopting this structure, corrosion-resistant steel intensity is higher, has corrosion stability, durable; Corrosion-resistant steel presents silvering simultaneously, especially matches with transparent piano.
Wheel disc is boss shape; After wheel disc screws in installing sleeve, the distance between the lower end of installing sleeve and the projection of wheel disc is less than 5 millimeters.After adopting this structure, installing sleeve is as far as possible many to be wrapped up wheel disc, and profile is more attractive in appearance.
The lower end of piano base is provided with the depressed area of the projection holding wheel disc.After adopting this structure, more compact structure, outward appearance is cleaner and tidier.
Be provided with the vertical shaft hole holding vertical shaft in wheel disc, the lower end in vertical shaft hole is provided with inner hexagonal hole; When projecting in the horizontal plane, vertical shaft hole is positioned at inner hexagonal hole or vertical shaft hole is inscribed within inner hexagonal hole.After adopting this structure, available Allen key inserts inner hexagonal hole, carries out rotation install wheel disc.During projection, vertical shaft hole is positioned at inner hexagonal hole or vertical shaft hole is inscribed within inner hexagonal hole, and namely vertical shaft hole is less than inner hexagonal hole, is convenient to the vertical shaft corresponding to vertical shaft hole dimension smoothly by inner hexagonal hole position.
The lower end of the outer wall of sleeve part is provided with chamfering.After adopting this structure, be convenient to sleeve part and insert jack.
An installation method for caster of piano, uses the mounting structure of caster of piano; Comprise the steps: that installing sleeve is first inserted jack by a. from top to bottom; B. again wheel disc is screwed in from the bottom up in the internal thread hole of installing sleeve until screw; C. finally vertical shaft to be loaded from the bottom up in the vertical shaft hole of wheel disc, complete the installation of caster of piano.Adopt in this way, easy for installation.
In step b, Allen key is used to be tightened onto on installing sleeve by wheel disc.Adopt in this way, easy for installation, laborsaving, screw better effects if.
Generally speaking, tool of the present invention has the following advantages: be applicable to transparent piano, and profile is succinctly attractive in appearance; Easy for installation, quick; Save threaded connector; Not easily loose, durable, even if through repeatedly installing and removing, also not easily skid.
