Specific implementation mode

As shown in Fig. 1~5, show the anti-loose structure of collapsible guitar described in the utility model include a body 10, One first support bar 20, a second support bar 30 and two binding modules 40.Wherein：

The body 10 is in elongated rod shape, and the back side is equipped with two screw cap holes 11.

The first support bar 20 is in long strip-board shape, and is located at the back side of the body 10 at qin tail.The first support bar 20 two long side shapes correspond to the shape of 10 corresponding section of body, and in the first support bar 20 towards one end shape of scroll head Cheng Youyi recess portions 21.The first support bar 20 be equipped with perforative 1 first perforation 22, this first perforation 22 outer end have compared with One first groove 23 of large aperture.

The second support bar 30 is in long strip-board shape, and be located at the back side of the body 10 far from qin tail at, the second support bar 30 two long side shapes correspond to the shape of 10 corresponding section of body, and in the second support bar 30 towards the first support bar 20 one end is formed with a protrusion 31 of corresponding 21 shape of recess portion, and make the protrusion 31 just for be embedded in relatively the recess portion 21 it In.The second support bar 30 is equipped with perforative 1 second perforation 32, and the outer end of second perforation 32 has the one of larger aperture Second groove 33.

Two binding modules 40, for the first support bar 20 and the second support bar 30 to be locked together in the body 10 respectively On.Each binding modules 40 include a bearing 41, a nut 42 and a bolt 43.The bearing 41 includes can concentric phase To the outer collar bearing 410 and an inner bearing collar 411 of rotation, which is embedded in first groove 23 (or should Second groove 33) among, and make the aperture design of first perforation 22 (or second perforation 32) at more than the inner bearing collar 411 Outer diameter, to avoid interfere with the inner bearing collar 411 rotation.42 circumferential surface of nut has external screw thread for being locked on the screw cap hole Among 11, it is equipped with a screw hole 420 in the nut 42, has the hex slot 421 of larger interior diameter for six in the outer end of the screw hole 420 Gusset hand or other tools are inserted embedding in order to by its turn.The bolt 43 spiral shell for the inner bearing collar 411 across the bearing 41 For lock in the screw hole 420, the outer end of the bolt 43 has a head 430 of larger outer diameter, the head 430 completely it is heavy be set to this first Among groove 23 (or second groove 33), and the medial surface on the head 430 is formed with outer diameter and is less than the convex of the outer collar bearing 410 Edge 431 interferes with the outer collar bearing 410 rotation for being butted on the inner bearing collar 411, to avoid the head 430.The head 430 There is lateral surface a driver slot 432, the driver slot 432 to wait other tools embedding for copper coin, a word bottle opener ... in strip channel form Enter with by its turn.The periphery on the head 430 is formed with a short slot 433, and half ring 44 is hubbed at this with an axis bolt 434 On head 430, keep half ring 44 swingable among the short slot 433 or to swing to the head 430 be in 90 degree of vertical State, in order to which the bolt 43 is rotated (as shown in Figure 6) by user's force.

After screwing the bolt 43, the flange 431 of 430 medial surface of head will be butted on the inner bearing collar of the bearing 41 On 411 lateral surface, when the first support bar 20 or the second support bar 30 are swung, the bearing being provided thereon can be driven 41 outer collar bearing 410 is rotated relative to the inner bearing collar 411.In this way, the bolt 43 just will not be by the first support bar 20 or the Two supporting rods 30 drive rotation, and then make its can first and second supporting rod 20,30 have the effect of adjustment swing angle under, Also the being firmly combined with property with the body 10 can be taken into account.Especially, degree can be screwed by adjusting the bolt 43, to penetrate the axis It is appropriate to generate to control the first support bar 20 or the second support bar 30 and the packing degree of the body 10 to hold 41 connection Frictional force so that have locating effect.

As shown in fig. 7, the second embodiment of the anti-loose structure for collapsible guitar described in the utility model, structure Roughly the same with above-described embodiment, difference is only that the head 430 of the bolt 43 of second embodiment is that outer diameter is less than the outer shaft Carrier ring 410 it is cylindric, and medial surface is butted on the lateral surface of the inner bearing collar 411, and lateral surface has a driver slot 432, the drive Dynamic slot 432 is hex shaped groove inserted for hexagon wrench or other tools it is embedding in order to by its turn.

The preferred embodiment that these are only the utility model, is not intended to limit the utility model, for this field Technical staff for, various modifications and changes may be made to the present invention.Within the spirit and principle of the utility model, Any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
