Abstract
The utility model relates to a long hinge on a piano cover plate. The long hinge comprises a first hinge component (1) and a second hinge component (2) which are provided with through holes (4) for installing screws, wherein a plurality of hinged shaft sleeves (3) which are staggered with each other are arranged between the first hinge component (1) and the second hinge component (2); and central holes of the hinged shaft sleeves (3) are sleeved on the same hinge shaft (5). The long hinge is characterized in that limit devices for preventing the hinge shaft (5) from moving out in the axial direction are arranged at two ends of the hinged shaft sleeves (3); and the axial limit devices are rivets, and the rivets are riveted at two ends of the hinged shaft sleeves, so that the hinge shaft can be prevented from moving out during the opening and closing of a piano top cover.
Description
Technical field
The utility model relates to a kind of hinge, particularly relates to the band andgudgeon chain on the piano cover plate.
Background technology
Band andgudgeon chain on the piano cover plate comprises first hinge member and second hinge member for the through hole of mounting screw at present; Be equipped with the hinge cover that staggers mutually between first hinge member and second hinge member; The centre bore axis of hinge cover all is located along the same line, the centre bore of hinge cover all is enclosed within on the hinge axis, but when the folding piano top cover, hinge axis is axially scurried out easily, can influence the stability of hinge like this, for these reasons, need a kind of hinge axis that can make badly and be limited to band andgudgeon chain on the piano cover plate in the hinge cover.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of hinge axis that can make to be limited in the hinge cover, the band andgudgeon chain on the piano cover plate that can shift out because of the folding piano top cover has not guaranteed its stability.
The technical solution of the utility model is: the band andgudgeon chain on a kind of piano cover plate, and it comprises first hinge member and second hinge member that is equipped with for the through hole of mounting screw; Be equipped with a plurality of hinge covers that stagger mutually between described first hinge member and second hinge member; The centre bore of described a plurality of hinge covers all is enclosed within on the same hinge axis; It is characterized in that: described hinge cover two ends are equipped be used to the stopping means that prevents that hinge axis from axially shifting out.
The utlity model has following advantage as can be seen according to such scheme: because the cover of the hinge on the band andgudgeon chain on this piano cover plate two ends are provided with the rivet for the fixed hinge axle, hinge axis is fixed in the hinge cover, can not shift out because of the folding piano top cover, so just guarantee the stability of the band andgudgeon chain on the piano cover plate.
As preferably, described stopping means is the rivet that is riveted on the outer end of two outermost end hinges covers, and rivet will prevent that hinge axis from shifting out, and guaranteed the stability of the band andgudgeon chain on the piano cover plate when the folding piano top cover like this.
As preferably, described stopping means is screw; Described screw screws in the hinge cover by the screwed hole on the outer end of two outermost end hinges cover, and screw screws in the hinge cover like this, and hinge axis just can not shift out the stability that has guaranteed the band andgudgeon chain on the piano cover plate when the folding piano top cover.
As preferably, the diameter of described rivet is 3 millimeters; The diameter of described hinge cover is 2.5 millimeters, and rivet just can be riveted in the hinge cover closely like this, can prevent that hinge axis from shifting out when the folding piano top cover, guaranteed the stability of the band andgudgeon chain on the piano cover plate.

The specific embodiment
Below in conjunction with accompanying drawing enforcement of the present utility model is further described.
Embodiment one: the band andgudgeon chain on a kind of piano cover plate, and it comprises first hinge member 1 and second hinge member 2 that is equipped with for the through hole 4 of mounting screw; The quantity of described through hole 4 is 40; Be equipped with a plurality of hinge covers 3 that stagger mutually between described first hinge member 1 and second hinge member 2; The centre bore of described a plurality of hinge covers 3 all is enclosed within on the same hinge axis 5; It is characterized in that: described hinge overlaps 3 two ends and is equipped be used to the stopping means that prevents that hinge axis 5 from axially shifting out.Described stopping means is the rivet 6 that is riveted on the outer end of two outermost end hinges cover 3.The diameter of described rivet 6 is 3 millimeters; The diameter of described hinge cover 3 is 2.5 millimeters.
Embodiment two: the band andgudgeon chain on a kind of piano cover plate, and it comprises first hinge member 1 and second hinge member 2 that is equipped with for the through hole 4 of mounting screw; The quantity of described through hole 4 is 40; Be equipped with a plurality of hinge covers 3 that stagger mutually between described first hinge member 1 and second hinge member 2; The centre bore of described a plurality of hinge covers 3 all is enclosed within on the same hinge axis 5; It is characterized in that: described hinge overlaps 3 two ends and is equipped be used to the stopping means that prevents that hinge axis 5 from axially shifting out.Described stopping means is screw 7; Screwed hole on the outer end of described screw 7 and two outermost end hinge covers 3 is spirally connected.
Below only be described with regard to most preferred embodiment of the present utility model, but can not be interpreted as it is limitations on claims.The utility model not only is confined to above embodiment, and its concrete structure allows to change.All various variations of doing in the protection domain of the utility model independent claims are all in the utility model protection domain.
