CN2315622Y - Fixing base for medium drum - Google Patents

Abstract

The utility model relates to a fixing base for a medium drum, which is arranged on the side edge of a drum. An iron pipe hole used by an iron pipe to penetrate through is transversally arranged in the inner part of a fixing base. The top of the iron pipe hole is provided with a concave groove; an I-shaped block is arranged in the inner part of the concave groove; a cambered surface which is arranged on the bottom part of the I-shaped block contacts closely on the iron pipe; the both sides of the I-shaped block, in the inner part of the concave groove, are respectively provided with an elastic strip; a screw bolt is longitudinally arranged on the top of the fixing base. A screw arbor at the bottom of the screw bolt just contacts closely on the top of the I-shaped block to fix the iron pipe; when the screw bolt loosens, the iron pipe can bounce to the original position by adopting the elastic strip. Thus, the utility model is caused to maintain the advantages of fairly smooth motion of the iron pipe and no scratch of the iron pipe when the iron pipe moves.

Description

Middle drum holder

The utility model relates to a kind of middle drum holder, belongs to the fixedly device of musical instrument.

At present in the combined type musical instrument that uses, except that " big drum ", " side drum " reach " brass cymbals ", " middle drum " played the part of considerable role, and the structure of " the middle drum " of general traditional type is: the side in middle drum is provided with a holder, be provided with an iron pipe hole in holder, in inside, iron pipe hole one iron pipe be set, the fixed form of this iron pipe is to utilize a bolt directly to press iron pipe, with the location iron pipe, such structure has following shortcoming:

This kind makes the mode of iron pipe stationary positioned, is to utilize bolt to provide the location in the mode that its screw rod directly presses iron pipe, because the mode of the screw rod of bolt compressing iron pipe is directly to push up the compressing of pulling, thereby iron pipe sustained damage.

Therefore, the practicality of drum fixed seat structure is unsatisfactory in the above-mentioned traditional type, and the necessity that is improved is arranged.

The purpose of this utility model provides and a kind ofly makes iron pipe slide smooth and easy and be difficult for the middle bulging holder of scratch iron pipe.

The purpose of this utility model be achieved in that a kind of in the drum holder, be provided with one for the fixing iron pipe hole of iron pipe, wherein in the inner transverse of holder:

The top in the iron pipe hole of described holder inside is provided with a groove, in inside grooves one worker's type piece is set, and the bottom faces of this worker's type piece is a cambered surface, and this cambered surface is positioned at the place, top in iron pipe hole,

Between the both sides of worker's type piece and bottom portion of groove, be respectively equipped with an elastic strip in described inside grooves,

Vertically to be provided with a screw, a bolt is screwed togather top down by screw at described groove top, and the screw rod bottom ejection of bolt below is in the place, top of worker's type piece.

Above-mentioned middle bulging holder, wherein: described elastic strip is made with excellent power glue.

The utlity model has following advantage:

The top in iron pipe of the present utility model hole is provided with a groove, in inside grooves one worker's type piece is set, the cambered surface of worker's type piece bottom just can be pushed up and be pulled on iron pipe, in worker's type piece both sides and be positioned at inside grooves and be respectively equipped with an elastic strip, in addition in the holder top so that a bolt vertically to be set, the screw rod of this bolt below just can push up pulls in worker's type piece top with fixing iron pipe, after bolt unscrews, can utilize the elasticity pop into position of elastic strip, thereby move can keep iron pipe to adjust the time sliding suitablely, and also have the advantage on not scratch iron pipe surface.

Accompanying drawing below in conjunction with an embodiment further specifies concrete structure of the present utility model:

Fig. 1 is the stereo appearance figure of an embodiment of the utility model.

Fig. 2 is the three-dimensional exploded view of each parts among Fig. 1.

Fig. 3 is the stereographic map of the utility model application example.

Fig. 4 is the cut-open view of Fig. 1.

Fig. 5 is analysing and observe of Fig. 1 and action diagram thereof.

The utility model is a kind of middle drum holder (as shown in Figure 1, 2), holder 10 of the present utility model slightly is a rectangular body, this holder 10 is sides (as shown in Figure 3) of drum 20 in can being arranged at, inner transverse in holder 10 is provided with an iron pipe hole 11, and iron pipe hole 11 is to be used for fixing iron pipe 30 (as shown in Fig. 4,5);

One groove 12 is formed on the top in the iron pipe hole 11 of holder 10 inside, can be in groove 12 inside for worker's type piece 13 is set, and the bottom of this worker's type piece 13 is formed with cambered surface 14, and 14 of this cambered surfaces are positioned at the place, top in iron pipe hole 11;

Be positioned at groove 12 both sides inner and that be positioned at worker's type piece 13 and be respectively equipped with an elastic strip 15, this elastic strip 15 is to make with excellent power glue, has elasticity.

Be can be with vertical formation one screw 16, one bolts 17 in addition by the screwing togather top down of screw 16 in groove 12 tops, but and screw rod 18 bottoms of bolt 17 belows are ejection location, place, top in worker's type piece 13.Said structure is after combination and when using (as shown in Figure 4), insert the inside in iron pipe hole 11 when iron pipe 30 after, be slightly larger than the aperture of iron pipe 30 because of the aperture that is surrounded between iron pipe hole 11 and the cambered surface 14, when desire will clamp iron pipe 30, be to utilize top swivel bolt 17, so that the screw rod 18 of bolt 17 belows pushes away worker's type piece for 13 times, also can make two elastic strips, 15 bottoms push against the wall place, bottom (as shown in Figure 5) of groove 12 really, because of two elastic strips 15 are to have buffering elasticity, so can be positively the cambered surface 14 of worker's type piece 13 bottoms be pushed against down in the top of iron pipe 30, so have the advantage that is difficult for scratch iron pipe 30, again when bolt 17 is unscrewed, the top of worker's type piece 13 is not then replaced in the bottom of screw rod 18, utilize the elasticity pop into position of two elastic strips 15, it is suitable that iron pipe 30 can quite be slided when moving adjustment, also has the advantage that is difficult for scratch iron pipe 30 surfaces simultaneously.
