This application has set up the combination mode that the sleeve pipe adds the steel cord core, has avoided the phenomenon of traditional nylon rope extension, and live time is lasting.

Description

Novel string tail rope

Technical Field

The utility model belongs to the technical field of stringed musical instrument technique and specifically relates to a novel string tail rope is related to.

Background

Violins can be roughly divided into violins, violas, cellos and bass violins, the quality of tone quality is the most fundamental identification of the violins, the timbre of the violins is greatly different due to the difference of materials, preparation methods, sizes, strings, paints and assembly, a given violin usually needs to be tuned to achieve the optimal timbre before use, a violin tail rope is a key part of tuning of the violins, a tailpiece is tied to a tailpiece through a tail post and a chord pillow, all tension forces from four strings are borne, most people think that the tail rope only pulls a tailpiece, is not a critical part, but the relationship between the tail rope and the panel is very close in reality, and the tail rope is another accessory which is directly contacted with the panel besides the bridge, if the quality of the tail rope is not too critical, other parts have good quality and are exquisite in manufacture, so that the quality of the violin is obviously reduced, and the playing effect of the violin is influenced.

In the fifties and sixties, tail ropes of violins are mostly made of cowhells, as an improvement, in the nineties, batch-produced 'nylon' tail ropes are mostly adopted, and the 'nylon' tail ropes have certain toughness and strength, but have the problem of lengthening the tail rope, are time-consuming and labor-consuming in the tuning process and frequently run, so that the violin player is very worried, and the inventor finds that a great number of violin manufacturers still adopt the 'nylon' tail ropes and have not solved the existing problems all the time.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a novel string tail rope.

To achieve the above object, the present invention adopts the following:

a novel string tail cord comprising: the device comprises a threaded screw, a nut, a rubber sleeve, a steel wire rope core and a sleeve; the rear half section of the threaded screw is provided with a hollow part, and the steel wire rope core is embedded into the hollow part; both ends of the steel wire rope core are connected with threaded screws; the steel wire rope core is sleeved with a sleeve, and two ends of the sleeve wrap the rear half part of the threaded screw; a nut is sleeved on the threaded screw, and an annular groove is formed in the nut; and a rubber sleeve is arranged in the groove.

Preferably, the sleeve is a heat-shrinkable rubber tube.

Preferably, the number of the rubber sleeves is three.

Preferably, the diameter of the hollow portion of the threaded screw is larger than the diameter of the wire rope core.

Preferably, the heat-shrinkable rubber tube is made of rubber.

The utility model has the advantages of it is following:

1. this application has avoided the direct contact of metal with the tailpiece to noise appears in avoiding.

2. This application has set up the combination mode that the sleeve pipe adds the steel cord core, has avoided the phenomenon of traditional nylon rope extension, and live time is lasting.

Detailed Description

In order to illustrate the invention more clearly, the invention is further described below with reference to preferred embodiments. It is to be understood by persons skilled in the art that the following detailed description is illustrative and not restrictive, and is not to be taken as limiting the scope of the invention.

In the description of the present invention, it should be noted that unless otherwise explicitly stated or limited, the terms "mounted," "connected" and "disposed" are to be construed broadly, and may for example be fixedly connected, disposed, detachably connected, disposed, or integrally connected and disposed. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1 to 3, a novel string tail rope comprises: the device comprises a threaded screw 1, a nut 2, a rubber sleeve 3, a steel wire rope core 4 and a sleeve 5; the rear half section of the threaded screw 1 is provided with a hollow part 101, the diameter of the hollow part 101 is slightly larger than that of the steel wire rope core 4, the steel wire rope core 4 is inserted into the hollow part 101 and is extruded by an extrusion machine in the prior art, and therefore the steel wire rope core 4 is fixed on the threaded screw 1.

Furthermore, both ends of the steel wire rope core 4 are connected with the threaded screws 1 in the above mode, and the two threaded screws 1 penetrate through the string pulling plate of the violin;

further, the sleeve pipe 5 is sleeved on the steel wire rope core 4, the sleeve pipe 5 is a heat-shrinkable rubber pipe, the heat-shrinkable rubber pipe is made of rubber materials, good sound insulation and a cushioning effect are achieved, the heat-shrinkable rubber pipe wraps the steel wire rope core 4, the rear half section of the threaded screw rod 1 is also wrapped, and when the sleeve pipe 5 wraps the rear half section of the threaded screw rod, the diameter of the sleeve pipe is larger than the maximum external thread diameter of the threaded screw rod.

Further, a nut 2 is sleeved on the threaded screw 1, and an annular groove 201 is formed in the nut 2; be provided with rubber sleeve 3 in the recess 201, the suit is in recess 201 in proper order for three in the quantity of rubber sleeve 3.

The working principle of the device is as follows: compare in traditional nylon rope tail rope, this application has avoided the direct contact of nut 2 with the tailpiece through setting up the rubber sleeve, sets up steel wire rope core 4 simultaneously, guarantees can not produce the phenomenon of lengthening because of the increase of live time.

Obviously, the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention, and it is obvious for those skilled in the art to make other variations or changes based on the above descriptions, and all the embodiments cannot be exhausted here, and all the obvious variations or changes that belong to the technical solutions of the present invention are still in the protection scope of the present invention.
