In addition, the three-dimensional spatial dimensions of length, width and depth should be included in actual production.

[0041] In order to make the purpose, technical scheme and advantage of the utility model more clear, the embodiments of the utility model will be described in further detail below in combination with the drawings.

[0042] The utility model provides a prevent loose structure for musical instrument, through the mutual cooperation of musical instrument installation structure and anti loosening structure, the screw and adjustable angle key are separated, so that the screw can be prevented from rotating when the adjustable angle key rotates, the purpose of preventing the screw from loosening is achieved, when the bolt is subjected to external force, the reverse force can be provided through the deformation of the spring and the preload formed by the compression of the spring, and the occurrence of loosening is delayed.

[0043] Figures 1 to 7 The whole structure schematic diagram of the embodiment of the utility model for prevent loose structure for musical instrument is shown, please refer to Figures 1 to 7 The main structure of the embodiment includes:

[0044] Musical instrument installation structure, including:

[0045] Support ring 12 is arranged in the hole position of the surface of the musical instrument shell 11. Specifically, the support ring 12 is used for supporting the rotation of the adjustable angle key 13;

[0046] Adjustable angle key 13 is mutually nested with the support ring 12. Specifically, the adjustable angle key 13 is used for adjusting the pitch and tone,

[0047] Step hole 14 is arranged on the top surface of the adjustable angle key (13). Specifically, the step hole 14 is used for containing the screw 21 and the spring 23;

[0048] Anti loosening structure, including:

[0049] Screw 21 penetrates the step hole 14. The screw 21 is used for cooperating with the nut 22 to complete locking and limiting;

[0050] Nut 22 is fixed to the inner bottom surface of the musical instrument shell 11, the nut 22 is connected with the screw 21, and the nut 22 is nested on the outer side of the screw 21;

[0051] Spring 23 is nested on the outer side of the nut 22, and the two ends of the spring 23 are respectively abutted with the step hole 14 and the head of the screw 21;

[0052] The length and position of the nut 22 are set to separate the screw 21 and the spring 23, to prevent large-area contact between the screw 21 and the spring 23, and to avoid synchronous rotation of the screw 21 and the spring 23.

[0053] It is better to abut one end surface of the nut 22 against the head of the screw 21 to completely separate the screw 21 and the spring 23.

[0054] Specifically, the screw 21 penetrates the stepped hole 14, and the screw 21 is connected with the nut 22, and the spring 23 is sleeved on the periphery of the nut 22, so that the spring 23 can separate the screw 21 and the adjustable angle key 13, so that the screw 21 can be prevented from rotating simultaneously when the adjustable angle key 13 rotates. The spring 23 is preloaded during installation, and the spring 23 will not interfere with the screw 21 due to deformation under stress.

[0055] That is, a certain pressure or torque is applied to deform and store elastic energy. The preloading force causes the spring 23 to generate a certain compression force, so that when the screw 21 is subjected to an external force, it can provide a reverse force to delay loosening. The spring 23 can deform to a certain extent when subjected to an external force. This deformation makes the contact surface of the spring 23 contact the screw 21 more tightly, increases the resistance of the spring 23 to the screw 21, and improves the anti-loosening effect.

[0056] Further, the two ends of the spring 23 are polished into flat surfaces 231.

[0057] Specifically, the flat surface 231 is designed to avoid interference between the end surface of the spring 23 and the screw 21 or the adjustable angle key 13, so that the screw 21 and the adjustable angle key 13 do not rotate together.

[0058] Further, the embodiment also includes an abutting structure, which comprises:

[0059] The threaded rod 31 is fixed at the end of the screw 21. Specifically, the threaded rod 31 is used to cooperate with the threaded compression ring 32 to complete reverse locking;

[0060] The threaded compression ring 32 is connected with the threaded rod 31. Specifically, the threaded compression ring 32 is threaded along the threaded rod 31;

[0061] The annular cylinder 33 is fixed with the threaded compression ring 32. Specifically, the annular cylinder 33 is used to drive the first friction surface 34 to shift and abut against the second friction surface 35;

[0062] The first friction surface 34 is arranged on the top surface of the annular cylinder 33; and

[0063] The second friction surface 35 is arranged on the bottom surface of the nut 22.

[0064] Specifically, the first friction surface 34 and the second friction surface 35 are in contact to increase the friction. The screw rod 31 is screwed in the opposite direction to the screw 21.

[0065] The threaded compression ring 32 is connected to the threaded rod 31, and the threaded compression ring 32 drives the annular cylinder 33 and the first friction surface 34 to move forward until the first friction surface 34 is in abutment with the second friction surface 35. Since the threaded rod 31 is screwed in the opposite direction to the screw 21, the threaded compression ring 32 is rotated in the opposite direction to the nut 22.

[0066] When the adjustable angle button 13 is rotated and the nut 22 is loose, the threaded compression ring 32 is rotated in the opposite direction to directly compress the nut 22, avoid loosening, and the two friction surfaces are in contact to increase the friction, further reducing loosening.

[0067] Although the utility model has been described above with reference to the embodiments, various improvements can be made and equivalent parts can be replaced without departing from the scope of the utility model. In particular, as long as there is no structural conflict, the features of the embodiments disclosed in the utility model can be combined in any way, and the combinations are not exhaustively described in the specification only for the purpose of saving space and resources. Therefore, the utility model is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
