detailed description

In the following, the present invention is further described with reference to the drawings and specific embodiments. It should be noted that, under the premise of no conflict, the embodiments described below or technical features can be arbitrarily combined to form a new embodiment. .

A portable musical instrument support frame shown in FIG. 1 includes a support portion 10, a support arm 20, and at least three legs 30; at least three legs 30 are disposed around a central axis of the support portion 10. At this time, at least three legs The legs 30 may be arranged in a circle, a square, etc., while at least three legs 30 are arranged at intervals; at least three of the legs 30 are rotatably mounted on the support portion 10, respectively, and can be in a close position and away from each other. Each of the legs 30 is formed with a first limiting surface 31; the supporting portion 10 is used to support a musical instrument, and at least three second limiting surfaces 11 are formed on the supporting portion 10, At least three of the second limiting surfaces 11 are arranged one-to-one with at least three of the legs 30, that is, each of the first limiting surfaces 31 is correspondingly provided with a second limiting surface 11; the second limiting surface 11 is used for Abutting with the first limiting surface 31 to limit the leg 30 to the first unfolding position; the support arm 20 is mounted on the leg 30 and can be collapsed when being folded on the leg 30 Between the position and the second extended position protruding to the outside of the leg 30; the support arm 2 A third limiting surface 21 is formed at 0; a fourth limiting surface 32 is formed on the leg 30 on which the support arm 20 is installed; the fourth limiting surface 32 is used for connecting with the third limiting surface The surface 21 abuts to limit the support arm 20 to the second extended position.

On the basis of the above structure, using the portable musical instrument support frame, at least three legs 30 are rotated to a first unfolded position far away from each other. At this time, the first limiting surface 31 and the second limiting surface 11 abut against each other. The support leg 30 is restricted to the first deployment position; the support arm 20 is rotated toward the outside of the support leg 30 and rotated to the second deployment position. At this time, the third limit surface 21 and the fourth limit surface 32 The abutment restricts the support arm 20 to the second unfolded position. In this way, the portable instrument support frame is unfolded, and then the bottom of the instrument is placed on the support arm 20, and the back of the instrument rests on the support portion 10; When the portable musical instrument supporting frame needs to be collapsed, the legs 30 are rotated to the close position close to each other, and the support arm 20 is rotated to the folded position of the legs 30 to reduce the overall volume of the portable musical instrument. And easy to carry.

It should be noted here that the above-mentioned support portion 10 may be a support case, a support rod, a support cylinder, or the like.

It can be known from the mechanical analysis that the triangular structure is the most stable. In this embodiment, preferably, the number of the legs 30 is three, and the three legs 30 are arranged in a circle around the central axis of the support portion 10, so, Stable support for musical instruments.

In order to achieve stable support for the musical instrument, the number of the supporting arms 20 is two, and the two supporting arms 20 are respectively installed on two adjacent legs 30 of the supporting arm 20; Abutting on the two support arms 20, the two support arms 20 support the instrument at the same time, which can improve the support stability; among them, in actual use, a non-slip structure can also be provided on the support arm 20 to prevent the instrument from opposing the support arm 20 The non-slip structure can be a mat made of an existing non-slip material, a non-slip protrusion provided on the support arm 20, or a non-slip groove pattern provided on the support arm 20.

In order to improve the overall non-slip performance of the portable musical instrument, it is preferred that a non-slip pad 40 is sleeved on the bottom of the leg 30; the non-slip pad 40 is a pad made of an existing non-slip material; The contact has frictional force, thereby preventing the leg 30 from moving relative to the external ground surface. Furthermore, the friction between the non-slip pad 40 and the external ground surface can be used as a force to restrict the rotation of the leg 30. In this way, the leg 30 can be freely adjusted. The opening angle further adjusts the overall height of the portable musical instrument support frame after being unfolded, which can be applied to musical instruments of different models and sizes.

Preferably, the non-slip pad 40 is an existing silicone pad; the non-slip pad 40 may also be a pad provided with non-slip protrusions, or may be a pad provided with non-slip grooves.

In order to prevent the musical instrument from sliding off the support arm 20 during the process of supporting the musical instrument, preferably, one end of the support arm 20 is mounted on the leg 30 and the other end forms a limiting portion 22; the limiting portion 22 is used for It is in contact with the bottom of the musical instrument. In this way, the stopper 22 is in contact with the musical instrument to prevent the musical instrument from moving relative to the support arm 20 and to prevent the musical instrument from falling off the support arm 20. It should be noted here that the above-mentioned limit The part 22 may be a limit block, a limit hook, a limit plate, and the like.

Specifically, the supporting portion 10 is formed with a supporting inclined surface 12 for supporting the back surface of the musical instrument. Thus, when the musical instrument is placed on the support arm 20, the musical instrument leans against the inclined surface. In actual use, a non-slip structure can also be provided on the support slope 12, and the non-slip structure can be a mat made of existing non-slip material, a non-slip protrusion or a non-slip groove.

In order to further reduce the overall volume of the portable musical instrument, further, the support portion 10 is formed as a storage area; the close position is located in the storage area, so that when at least three of the legs 30 are brought close together, The position directly below the support portion 10 is further reduced by adopting the position directly below the support portion 10.

Specifically, when at least three of the legs 30 are in the close position, at least three of the legs 30 collectively form a cylindrical shape.

The above embodiments are only preferred embodiments of the present invention, and the scope of protection of the present invention cannot be limited by this. Any insubstantial changes and substitutions made by those skilled in the art based on the present invention belong to the present invention. Claimed scope.
