Description
[technical field]
The utility model relates to equipment locking field, is specifically related to the latch assembly of the frame drum drum in musical instrument field.
[background technology]
In musical instrument stand drum field, drum is arranged on drum pipe by drum snap close.Drum in the market latches in drum when being impacted, and easily and between drum pipe produces relative rotation; In order to avoid relatively rotating, drum snap close is designed to be fixedly connected with drum pipe, and now drum angle can not adjust again.It is very inconvenient to use, and brings many puzzlements to drummer or adjustment person.
[summary of the invention]
In view of this, the latch assembly that the utility model provides a kind of structure to improve, for locking the drum of frame drum, can easily adjust the angle of drum or the relative drum pipe of snap close simultaneously.
The utility model adopts following technical scheme, and the latch assembly of structure anti-rotation adjustable-angle again, comprises snap close in a tubular form and snap close lining, pipe fitting, set nut; There is snap close lining in snap close, in snap close lining, have pipe fitting; Snap close inner wall belt sawtooth, pipe sidewall is provided with the opening with its axis being parallel; Snap close lining inwall is provided with the convex tendon with its axis being parallel, and outer wall is provided with the sawtooth of energy and snap close inwall engagement, and snap close lining sidewall is provided with the opening with its axis being parallel; Pipe fitting outer wall is provided with at least one groove coordinated with snap close lining convex tendon; Set nut can be locked and unclamp snap close.
Preferably, described snap close lining two ends outer wall is provided with the flange higher than snap close lining sawtooth point circle.
Preferably, another snap close that the sidewall relative with latch openings is provided with axis and described snap close axes normal is latched in described in.
Advantageous Effects of the present utility model is:
1., during locking state, snap close and snap close lining are when locking state, and engagement each other, can prevent from occurring each other relatively rotating; By the cooperation of convex tendon and groove between snap close lining and pipe fitting, achieve the function of anti-rotation.During releasing orientation, the opening of snap close and snap close lining is opened, and snap close lining can rotate in snap close, can realize and snap close connect object and pipe fitting between angular setting.
2. the flange at snap close lining two ends can prevent snap close lining from deviating from from snap close when locking state.

The latch assembly STRUCTURE DECOMPOSITION schematic diagram of the adjustable-angle again of the anti-rotation in Fig. 1 embodiment one;
The C-C diagrammatic cross-section of the latch assembly releasing orientation of adjustable-angle again of the anti-rotation in Fig. 2 embodiment one;
The C-C diagrammatic cross-section of the latch assembly locking state of adjustable-angle again of the anti-rotation in Fig. 3 embodiment one.
[embodiment]
In order to make the technical scheme of this patent and technique effect clearly, be described in detail below in conjunction with the embodiment of drawings and Examples to this patent.
Embodiment one:
As Fig. 1 to Fig. 3, the latch assembly of the adjustable-angle again of the anti-rotation in the present embodiment, comprises snap close 1, snap close lining 2, pipe fitting 3, set nut 4.
Snap close 1 in a tubular form, inside pipe wall band sawtooth 1a, sawtooth can be double wedge or recessed tooth; Pipe sidewall is provided with the opening 1b with snap close axis being parallel, and opening two edges are provided with the lock ear 1c of Intermediate Gray screw, 1d; The sidewall relative with opening 1b is provided with the snap close 1e of fixing drum support bar (not shown), and the axis of snap close 1e and the axes normal of snap close 1, set nut 5 is located in the lock ear at snap close 1e edge.
Snap close lining 2 in a tubular form, inside pipe wall be provided with snap close lining 2 axis being parallel and run through the convex tendon 2a at snap close lining 2 two ends; Pipe outer wall is provided with the sawtooth 2b engaged with snap close 1 sawtooth 1a, if sawtooth 1a is recessed tooth, sawtooth 2b is exactly double wedge, and vice versa; Pipe sidewall is provided with the opening 2c with axis being parallel; Snap close lining 2 two ends outer wall is provided with the flange 2d higher than sawtooth 2b point circle.
Pipe fitting 3 outer wall be provided with at least 1 with snap close lining 2 convex tendon 2a coordinate groove 3a, the cross sectional shape of groove 3a and the cross sectional shape of convex tendon 2a suitable.
Set nut 4 comprises bolt 4a, pad 4b, wing nut 4c; Pad 4b is positioned at the screw exit outside lock ear 1c, and bolt 4a is successively through locking ear 1d, 1c, pad 4b, wing nut 4c.
When installing drum, because snap close 1 and snap close lining 2 exist opening, snap close lining 2 easily inserts in snap close 1, and pipe fitting 3 easily inserts snap close lining 2.Snap close lining 2 is inserted in snap close 1, two end boss 2d of snap close lining 2 expose snap close 1 edge, now can relatively rotate between snap close 1 and snap close lining 2, pipe fitting 3 is inserted in the assembly of snap close lining 2 and snap close 1, now pipe fitting 3 unit with grooves in outer wall 3a engages with snap close lining convex tendon 2a, can prevent relatively rotating between pipe fitting 3 and snap close lining 2; Now do not have between snap close lining 2 and pipe fitting 3 and relatively rotate, but snap close 1 and pipe fitting 3, still can relatively rotate between snap close 1 and snap close lining 2.Finally the support bar with drum is inserted in snap close 1e, tighten set nut 5, be fixed on snap close 1 by drum.Tighten set nut 4, the opening of snap close 1 and snap close lining 2 all draws in, and the sawtooth 1a of snap close 1 inwall and the sawtooth 2b of snap close lining 2 outer wall closely engages, and can prevent relatively rotating between snap close lining 2 and snap close 1.The flange 2d at snap close lining 2 two ends, at locking state, exposes snap close 1 edge, can prevent snap close lining 2 from deviating from from snap close 1.
Unscrew set nut 4, the opening of snap close 1 and snap close lining 2 all launches, and snap close lining 2 has movable space in snap close 1 inside, snap close lining 2 can rotate relative to snap close 1, therefore realizes the angular setting of drum relative to the angle of pipe fitting 3 by adjustment snap close 1.
Drum in the present embodiment can not be arranged in snap close 1e, also can be fixedly connected with snap close 1.The object fixing when snap close 1 is not drum, but during other products, and the latch assembly of the adjustable-angle again of the anti-rotation in the present embodiment can at other field, realize anti-rotation fastening and regulate the function of fixed object angle.
The foregoing is only the preferred embodiment of this patent, be not limited to this patent, for a person skilled in the art, this patent can have various modifications and variations.Within all spirit at this patent and principle, any amendment done, equivalent replacement, improvement etc., within the protection domain that all should be included in this patent.
