Description

Musical instrument frame capable of preventing transverse swinging Technical Field The utility model relates to the technical field of musical instrument frames, in particular to a musical instrument frame capable of preventing transverse swinging. Background The musical instrument frame is a daily household supporting device for musical instruments such as electronic musical instruments and zither, and because the musical instrument frame occupies indoor space, the existing household musical instrument frame is designed into a detachable assembly structure, and the musical instrument frame is assembled when in use, but not disassembled and stacked when in use. However, the cross rod and the upright rod of the traditional piano frame are directly connected by 90-degree radial penetration of the round tube and then are fixed by screws, but the connection mode can be unstable along with the prolonging of the service life and the increasing of the disassembly and assembly times, and particularly the transverse round tube is easy to enable the whole piano frame to swing left and right after being inserted in the vertical round tube, so that the support of the piano body is unstable. Therefore, how to design a musical instrument frame, on the basis of ensuring the original detachable function, the connection mode of the upright rod and the transverse rod is optimized, and the relative torsion displacement of the upright rod and the transverse rod after the upright rod and the transverse rod are prevented from being connected, so that the musical instrument frame becomes a technical problem to be solved urgently by the person in the field. Disclosure of utility model The utility model aims to solve the defects of the prior art and provides a musical instrument frame capable of preventing transverse swinging, which adopts a connecting mode that a transverse square tube is inserted into a vertical round tube, the relative torsion displacement of the square tube and the round tube is avoided, so that the stability of the musical instrument frame is improved, and the musical instrument frame is simple in structure, low in cost and easy to realize. The utility model provides a musical instrument frame of preventing transversely swaing, it is X to define the direction of transversely swaying, the direction is Y to the musical instrument frame fore-and-aft direction, vertical direction is Z to, musical instrument frame includes two risers that Z set up, the upper portion and the lower part of these risers all have seted up the square hole that link up along Y to, all peg graft in the square hole that link up has the square pipe of upper side and lower side of two risers, the both ends of these square pipe of upper side and lower side all peg graft along X to and along Z to fix in the square hole that link up inside, prevent musical instrument frame take place transversely swaying on XZ vertical plane by the inner wall in square hole that links up with the outer wall in square pipe of upper side and lower side. Preferably, the two ends of the upper square pipe and the lower square pipe are fixedly inserted with connecting blocks, a counterforce block with the side length larger than that of the through square hole is buckled and fixed on one opening end of the through square hole, a fastening bolt penetrates through the counterforce block along the Y direction and is rotationally connected with the counterforce block, and a threaded section of the fastening bolt penetrates through and is meshed with the connecting blocks. Preferably, the bottom of the lower pipe is rotatably connected with a plurality of casters. The utility model has the advantages and technical effects that: According to the transversely-swinging-preventing musical instrument frame, the upper square tube and the lower square tube are inserted and positioned in the through square hole of the vertical tube along the X direction, the upper square tube and the lower square tube are fixed with the Y direction of the vertical tube through the counter-force block, the fastening bolt and the connecting block, in addition, the outer walls of the upper square tube and the lower square tube are matched and inserted in the through square hole of the vertical tube, the upper square tube and the lower square tube are restrained on the XZ vertical plane through the inner wall of the through square hole, so that the upper square tube and the lower square tube are prevented from being uncontrollably twisted on the vertical tube, the aim of transversely swinging the musical instrument frame can be achieved even if the fastening bolt is not completely screwed, and the transversely-swinging-preventing musical instrument frame is obviously superior to the connecting mode of the bolt fixing after the double round tubes are mutually inserted in the prior art.
