CN201556407U - Erhu with detachable instrument head - Google Patents

Abstract

The utility model discloses an Erhu with a detachable instrument head. The Erhu comprises an instrument barrel connected with one end of an instrument stem, and an instrument axis is arranged in the axial direction perpendicular to the instrument stem. The Erhu also comprises an instrument head with an inner cavity, internal threads are formed in the cavity, and external threads corresponding to the internal threads are formed at the other end of the instrument stem. A clamp device is arranged at the bottom of the external threads, so that when the external threads and the internal threads are tightly clamped, the direction of the instrument head and that of the instrument axis are the same. The Erhu with the detachable instrument head provided by the utility model utilizes the threads to connect the instrument head and the instrument stem, so that when the Erhu is in use, the instrument head and the instrument stem are connected into a whole, and when the Erhu is not used, the instrument head can be detached for storage, thereby avoiding the fracture of the instrument head caused by impact.

Description

The dismountable urheen of a kind of scroll head

Technical field

The utility model belongs to the musical instrument technical field, is specifically related to the dismountable urheen of a kind of scroll head.

Background technology

Musical instrument in use has unavoidably and collides with, and can bring damage in various degree.For the folk music urheen, the place of most fragile is a scroll head, because the junction of scroll head and qin bar is too thin, easily fracture especially behind the qin box of packing into, is walked on the road of jolting or being subjected to external force clashes, in these cases, often the most impaired is scroll head, and it can disconnect with the qin bar.

Summary of the invention

The purpose of this utility model provides the dismountable urheen of a kind of scroll head, has solved existing urheen scroll head and has fixed, and is clashed into easily when carrying and the problem that ruptures.

The technical scheme that the utility model adopted is, the dismountable urheen of a kind of scroll head, comprise the qin tube, one end of qin tube and qin bar is connected, perpendicular to the qin bar axially be provided with the qin axle, also comprise scroll head, the inside of scroll head is cavity, be provided with internal thread in the cavity, the other end of qin bar is provided with and the corresponding external thread of internal thread.

Characteristics of the present utility model are that also externally threaded bottom wherein is provided with gripping mechanism, and when making external thread and internal thread chucking, scroll head is identical with the direction of qin axle.

The beneficial effects of the utility model are, by scroll head and the qin bar of being threaded, during use scroll head and qin bar are connected as a single entity, and when not using scroll head are pulled down and deposit, thereby avoided scroll head to be clashed into and rupture.

Description of drawings

Fig. 1 is the structural representation of the dismountable urheen of the utility model scroll head;

Fig. 2 is the user mode synoptic diagram of the dismountable urheen of the utility model scroll head.

Among the figure, 1. qin tube, 2. qin bar, 3. scroll head, 4. qin axle, 5. internal thread, 6. external thread, 7. gripping mechanism.

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.

The structure of the dismountable urheen of the utility model scroll head, as shown in Figure 1, comprise qin tube 1, one end of qin tube 1 and qin bar 2 is connected, the other end of qin bar 2 is provided with external thread 6, perpendicular to qin bar 2 axially be provided with qin axle 4, also comprise innerly being the scroll head 3 of cavity, be provided with in the cavity and external thread 6 corresponding internal threads 5.The bottom of external thread 6 is provided with gripping mechanism 7, and when making external thread 6 and internal thread 5 chuckings, scroll head 3 is identical with the direction of qin axle 4.

When using urheen to play, as shown in Figure 2, scroll head 3 is screwed on the qin bar 2, the sensing after making scroll head 3 fixing is identical with qin axle 4, can play.When performance finishes, back out scroll head 3 and can deposit scroll head 3 separately, thereby avoided scroll head 3 owing to bump ruptures.Simultaneously, urheen, can join a plurality of scroll heads,, reach effect attractive in appearance, only need guarantee when making that the scroll head produced and qin screw thread can be inlayed to get final product as tap, head of the horse etc. for same.

The dismountable urheen of the utility model scroll head by scroll head and the qin bar of being threaded, during use is connected as a single entity scroll head and qin bar, when not using scroll head is pulled down and deposits, thereby avoided scroll head to be clashed into and rupture.
