Abstract

The utility model discloses a foldable musical instrument frame, which comprises a first top tube (1), a second top tube (1'), a first bottom tube (10), a second bottom tube (10'), two outer supporting tubes (2) and two inner supporting tubes (8). Centers of the two outer supporting tubes (2) and the two inner supporting tubes (8) are mutually connected via a rotating shaft (5), a handle is arranged at one end of the rotating shaft (5), a limiting cover (9) is disposed at the other end of the rotating shaft (5), bearings are arranged at connection positions of the inner supporting tubes (8) with the rotating shaft (5), inner gears (3) are disposed at connection positions of the outer supporting tubes (2) with the rotating shaft (5), correspondingly, outer gears (6) are fixed on the rotating shaft (5), and the inner gears (3) mesh with the outer gears (6). The foldable musical instrument frame is convenient for adjusting the angle between each outer supporting tube and each inner supporting tube, and the height of the musical instrument frame can be conveniently adjusted according to needs of a player. In addition, the foldable musical instrument frame is convenient in use, stable in structure, easy to be folded and convenient in storage and carrying.

Description

Folding qin frame

Technical field

The utility model relates to a kind of support, especially a kind of folding qin frame.

Background technology

At present, the musical instrument that various volumes are bigger, all needs to be placed on the table top when it is played for the ease of playing as mellotron, Zheng, seven-stringed plucked instrument in some ways similar to the zither etc., therefore no matter is in school or in the family, is necessary for table top of the special outfit of qin.But move above-mentioned musical instrument if desired or carry above-mentioned musical instrument when going out, must move or carry relevant table top, cause very inconvenience of user.

At the problems referred to above, some collapsible qin framves have appearred at present, after launching, common collapsible qin frame is the X type of capitalization.Though existing collapsible qin frame has been realized folding, when the height of qin frame is adjusted, need adjust its angular setting and fixing cumbersome, and the structural instability of whole qin frame to the angle between the stay pipe that constitutes X-shaped qin frame.

Summary of the invention

The purpose of this utility model is to provide a kind of folding qin frame, and it is simple in structure, and is easy to use, Stability Analysis of Structures, and can adjust the angle between the qin frame stay pipe and the height of qin frame easily.

In order to reach above purpose, the technical scheme that the utility model adopted is: a kind of folding qin frame, comprise first push pipe, second push pipe, the first pin pipe, the crus secunda pipe, two outer stay pipes and two interior stay pipes, first push pipe, second push pipe, the first pin pipe and crus secunda pipe are parallel to each other, first push pipe interconnects by the two outer stay pipes and the first pin pipe, second push pipe interconnects by two interior stay pipes and crus secunda pipe, it is characterized in that: the center of stay pipe interconnects by rotating shaft in the two outer stay pipes and two, one end of its shaft is provided with handle, the corresponding other end is provided with the limited cover that is positioned at the outer stay pipe outside, the junction of interior stay pipe and rotating shaft is provided with bearing, the junction of outer stay pipe and rotating shaft is provided with annular wheel, be fixed with outer rotor in the corresponding rotating shaft, annular wheel and outer rotor are meshing with each other, rotating shaft is provided with register pin near a side of handle, and the register pin slip cap is in rotating shaft, and the lateral wall of corresponding outer stay pipe is provided with groove.

The utility model is also implemented by following measure:

The end of described first push pipe, second push pipe, the first pin pipe and crus secunda pipe is equipped with protective sleeve, and protective sleeve generally adopts rubber sleeve or plastic jacket.

The beneficial effects of the utility model are: by rotating shaft is set, are convenient to adjust the angle between outer stay pipe and the interior stay pipe, can adjust the height of qin frame easily according to player's needs, and easy to use; In addition, this qin shelf structure is stable, and is easily folding, is convenient to take in and carry.

Description of drawings

Fig. 1 is a right view of the present utility model;

Fig. 2 looks cut-open view for master of the present utility model.

Embodiment

Make the utility model with reference to attached Fig. 1 and 2.This folding qin frame, comprise first push pipe 1, second push pipe 1 ', the first pin pipe 10, crus secunda pipe 10 ', two outer stay pipes 2 and two interior stay pipes 8, first push pipe 1, second push pipe 1 ', the first pin pipe 10 and crus secunda pipe 10 ' are parallel to each other, first push pipe 1 interconnects by the two outer stay pipes 2 and the first pin pipe 10, second push pipe 1 ' interconnects with crus secunda pipe 10 ' by two interior stay pipes 8, it is characterized in that: the center of stay pipe 8 interconnects by rotating shaft 5 in the two outer stay pipes 2 and two, when qin frame in opened condition the time, be the X type between outer stay pipe 2 and the interior stay pipe 8, one end of its shaft 5 is provided with handle, be used to make rotating shaft 5 rotations, the corresponding other end is provided with the limited cover 9 that is positioned at outer stay pipe 2 outsides, limited cover 9 is used to limit rotating shaft 5 position in the horizontal direction, interior stay pipe 8 is provided with bearing 7 with the junction of rotating shaft 5, be for being rotationally connected between rotating shaft 5 and the interior stay pipe 8, outer stay pipe 2 is provided with annular wheel 3 with the junction of rotating shaft 5, be fixed with outer rotor 6 in the corresponding rotating shaft 5, annular wheel 3 is meshing with each other with outer rotor 6, when being rotating shaft 5 rotations, driving outer rotor 6 rotates, by the engagement of outer rotor 6 with annular wheel 3, outer stay pipe 2 is rotated thereupon, thereby internally the angle between stay pipe 8 and the outer stay pipe 2 is adjusted, the height of qin frame also changes thereupon, rotating shaft 5 is provided with register pin 4 near a side of handle, register pin 4 slip caps are in rotating shaft 5, and and be between the rotating shaft 5 and be rotationally connected, the lateral wall of corresponding outer stay pipe 2 is provided with groove, when register pin 4 is arranged in the groove, outer stay pipe 2 is fixed, this moment, outer stay pipe 2 was not with rotating shaft 5 rotations, the stability that has guaranteed to play qin frame in the process.

The end of described first push pipe 1, second push pipe 1 ', the first pin pipe 10 and crus secunda pipe 10 ' is equipped with protective sleeve, and described protective sleeve generally adopts rubber sleeve or plastic jacket.

When using this qin frame, at first, each stay pipe is opened, made rotating shaft 5 rotations, and drive outer stay pipe 2 rotations, the height of qin frame is adjusted, make it satisfy player's needs by handle.After reaching the use height, in the groove in the outer stay pipe 2 of register pin 4 insertions, whole qin frame is fixed, the player can play the musical instrument that is placed on the qin frame.After using end, register pin 4 is extracted in the groove of outer stay pipe 2, rotating shaft 5 makes outer stay pipe 2 rotations, angle in making between stay pipe 8 and the outer stay pipe 2 reduces gradually, until interior stay pipe 8 with outside stay pipe 2 overlap fully, thereby realized the folding of 2 qin framves, be convenient to taking in and carrying of qin frame.
