Abstract
The utility model relates to a percussion instrument silencer, in particular to an adjustable support for a drum silencer, which comprises two hinge mounts hinged with each other, a supporting rod, a mounting seat and a rotation adjusting mechanism, wherein the right end of the supporting rod is provided with one pairs of mounting holes on the upper portion and one pairs of mounting holes on the lower portion, and is installed on the mounting seat through a rotating shaft and the rotation adjusting mechanism. The support is characterized in that each of two sides of the mounting seat extends to form a supporting arm, a plurality of mounting holes are arranged along the longitudinal direction of the supporting arm, a total length of the support varies when the supporting rod is installed in different mounting holes, the supporting rod also can be divided into two sections and the total length of the support can be further adjusted by means of controlling an overlap amount so that the support can be matched with drums with various diameters. The adjustable support for drum silencer has the advantages of being light in structure, flexible in rotation, and capable of adjusting the total length of the support. Adjustable supports in the same type can be matched with drums with various diameters. Accordingly product specification is reduced and production cost is lowered.
Description
Technical field
The utility model relates to a kind of percussion instrument quieter, relates in particular to a kind of support of frame drum exhaust box.
Background technology
Frame drum is a kind of Western percussion music of circle; Sound is very big when beaing performance; But student and the drummer this very big sound when carrying out frame drum exercise will produce the problem that disturbs residents, and application number is that 201110197121.6 Chinese invention patent application documents disclose a kind of frame drum exhaust box, and this exhaust box comprises rubber blanket, support bar and mount pad; Rubber blanket is installed on the back up pad; Back up pad is installed in the left end of support bar, and the right-hand member of support bar is installed in through two rotating shafts on the mount pad with rotation pushing mechanism, and it is the axle center rotation with a rotating shaft of right-hand member that this rotation pushing mechanism can make support bar.The support weak point of this exhaust box is: the total length of support is fixed, and is inconvenient to regulate, because frame drum varies; Diameter does not wait from 20cm-56cm, guarantee to be positioned at when silencing pad is propped up the center of eardrum, then the drum of different-diameter; Will dispose the different exhaust box of stent length, that rouses is of a great variety, causes the specification of exhaust box support also a lot; Can not be general, convenient inadequately during production; The support bar majority of similar products is to adopt square tube to make, and cost is higher.
Summary of the invention
The problem that the utility model will solve provides a kind of support of frame drum exhaust box, and this supporting structure is slim and graceful, adjustable length, can adapt to the frame drum of different model.
For addressing the above problem; The technical scheme that the utility model adopts is: the adjustable support of frame drum exhaust box, comprise two hinge seats that are hinged, support bar, mount pad and rotation governor motion, and the support bar right-hand member is established two pairs of mounting holes up and down; Support bar is installed on the mount pad through rotating shaft and rotation governor motion; It is characterized in that: a sway brace is respectively stretched out on the both sides of mount pad, is provided with a plurality of mounting holes on the sway brace along its length, in the time of in support bar is installed in different holes; The total length of support is just different, thereby adapts to the frame drum of different-diameter.
The another scheme of the utility model, about support bar is divided into two sections, about two sections can be fixed together through overlap joint, through the amount of lap of control different length, also can adjust the total length of support.
The further improvement of the utility model, the xsect of said support bar or side view are the U-shaped structure, and this compares slimmer and more graceful with rhs-structure; Said rotation governor motion comprises tommyhead bolt and the sleeve that has internal thread; The cross bar of tommyhead bolt is installed in the hole on the support bar and can freely rotates; A screwed end is connected with the sleeve that has internal thread; The other end of sleeve is provided with the polygonal head that can spanner cooperates, and sleeve is installed on the mount pad through self-aligning ball bearing, uses self-aligning ball bearing can make sleeve pipe when adjustment, can rotate freely, swing.During use the mount pad in the utility model is fixed on the inboard drum wall of frame drum, polygonal head passes bulging wall and reaches the bulging outside, uses spanner to rotate polygonal head and can promote support bar and rotate along rotating shaft.
Compared with prior art, the beneficial effect of the utility model is: structure is slim and graceful, rotates flexibly, and the total length of support can be regulated, and can be applicable to a kind of adjustable support of model and the frame drum of multiple different-diameter reduce product specification, reduces production costs.

Embodiment
Embodiment 1:
Shown in Fig. 1-3; The utility model comprises two hinge seats that are hinged 2, support bar 4, mount pad 11 and rotates governor motion; Support bar 4 right-hand members are established two pairs of mounting holes up and down; Support bar 4 is through rotating shaft 6 and rotation governor motion and 11 alive connections of mount pad, and a sway brace 10 is respectively stretched out on the both sides of mount pad 11, is provided with a plurality of mounting holes 8 on the sway brace 10 along its length; The xsect of support bar (4) or side view are the U-shaped structure; Said rotation governor motion comprises tommyhead bolt 7 and the sleeve 9 that has internal thread; The cross bar 5 of tommyhead bolt 7 is installed in the hole on the support bar 4 and can freely rotates; A screwed end is connected with the sleeve that has internal thread 9; The other end of sleeve 9 is provided with the polygonal head 13 that can spanner cooperates, and sleeve 9 holds through aligning ball journal 12 and is installed on the mount pad 11; Be welded on above the hinge seat 2 on the pallet 3 below the silencing pad 1, be welded on the support bar (4) below the hinge seat 2.
Diameter according to frame drum during use is different; Support bar 4 is installed in the different mounting hole 8; Make support total length with the drum big or small corresponding, silencing pad 1 can withstand the center of eardrum 15, the mount pad in the utility model 11 is fixed on the inboard of the bulging wall 14 of frame drum again; Polygonal head 13 passes bulging wall 14 and reaches the bulging outside, rotates polygonal head 13 with spanner and can promote support bar 4 and rotate freely along rotating shaft 5.
Embodiment 2:
As shown in Figure 4, the difference of present embodiment and embodiment 1 be support bar 4 be divided into about two sections, about two sections can be fixed together through overlap joint, through the amount of lap of control different length, also can adjust the total length of support.
The utility model promptly can use mounting hole different on the sway brace 10 8 to reconcile the total length of support separately; Also can use separately support bar 4 is divided into about two sections; Method through the control amount of lap is reconciled total length, can also use above-mentioned two kinds of schemes to reconcile the total length of support simultaneously.
