Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of manufacturing guitar and electric guitar strap buttons, in particular to a guitar strap safety buckle. Background Art
[0002] A guitar is a commonly used instrument in live performances. When using it to accompany singing, a strap is needed to carry it on the performer. The connection of the strap on the guitar requires the use of a safety buckle, and the connection between the strap and the guitar is achieved by buckling the safety buckle on the guitar endpin.
[0003] Since the end of the guitar endpin for connecting the strap has a larger volume than the root and has a structure similar to a coronal groove, some safety buckles for connecting the strap use two circular holes with different diameters and connected to each other. After the safety buckle is sleeved from the end of the guitar endpin, the smaller-diameter circular hole is then sleeved in the middle of the guitar endpin. Finally, a limiting component is arranged between the two circular hole structures to limit their connectivity, so as to realize the connection between the safety buckle and the guitar endpin. Although the safety buckle with the above structure can achieve the connection effect with the guitar endpin, if there are defects in the limiting effect of the limiting component on the connectivity of the two circular hole structures with different diameters, the strap is likely to become loose during the performance of the performer, resulting in the guitar falling off. To avoid the phenomenon of the strap becoming loose, the limiting components set on some safety buckles for connecting guitar straps will adopt complex structures to pursue the purpose of firm connection. The operation process of setting the limiting component at the designated position is also relatively complex. And sometimes the safety buckle also needs to be removed from the guitar to facilitate the placement of the guitar. If the connection firmness of the limiting component is too strong, the operation of removing the safety buckle from the guitar endpin will be very laborious. Summary of the Utility Model
[0004] Aiming at the above technical deficiencies, the utility model provides a safety buckle that can quickly connect and disconnect between the safety buckle and the guitar endpin by squeezing the limiting plate to turn up the guitar endpin, so that the guitar endpin enters the matching space, thereby connecting the guitar strap to the guitar endpin, with simple operation.
[0005] To achieve the above object, the utility model is realized through the following technical solutions:
[0006] The utility model discloses a guitar strap safety buckle, which comprises a fastener body, one end of which is provided with a belt threading ring with a belt threading opening, a limiting groove is arranged inside the fastener body, the end of the limiting groove away from the belt threading ring is stepped, a limiting plate is connected inside the end of the limiting groove close to the belt threading ring, the limiting plate is connected to the fastener body through a connecting component, the limiting plate rotates with the end connected to the connecting component as the rotation center to form an opening for the guitar tail nail to pass through, a recess is arranged at the end of the limiting plate away from the connecting component, the recess and the end of the limiting groove away from the belt threading ring form a matching space for matching outside the guitar tail nail to realize the connection between the fastener body and the guitar tail nail, and the cross-sectional shape of the end of the limiting groove close to the belt threading ring is the same as the cross-sectional shape of the part of the other end of the limiting groove close to the opening side.

[0008] Furthermore, a groove is provided on the wall surface of the fastener body outside the inner cavity, and shaft columns that fit in the groove are provided on both sides of the middle part of the limit plate. The two pins of the torsion spring extend in the same direction to the inner cavity space close to the outside of the shaft column, and one of the pins is pressed against the surface of the shaft column.
[0009] Furthermore, a first limit block is provided on the end wall of the inner cavity away from the connecting shaft and the groove side, and one of the pins of the torsion spring extends into the inner cavity space outside the first limit block, and a second limit block is provided on the end of the shaft column away from the limit plate, and the other pin of the torsion spring extends into the inner cavity space outside the second limit block.

[0012] Furthermore, the outer walls on both sides of the fastener body are provided with an anti-slip pattern.
[0013] The beneficial effects of the utility model are:
[0014] When the safety buckle is installed on the guitar tail nail, it is squeezed on the guitar tail nail through the limiting plate, so that the opening formed by the turning up of the limiting plate and the limiting groove form enough space for the end of the guitar tail nail to enter the matching space. After the guitar tail nail enters the matching space, the safety buckle and the guitar tail nail are connected. Since the end of the guitar tail nail is too large, the guitar tail nail is restricted by the limiting plate after entering the matching space, and the guitar tail nail can only slide in the limiting groove and cannot be separated from the limiting groove, thereby realizing the connection of the guitar strap to the guitar tail nail. The operation is simple, and the safety buckle and the guitar tail nail can be quickly connected and separated. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode
[0027] The utility model discloses a safety buckle for a guitar strap. As Figures 1 - 5 shown in combination, the safety buckle includes a fastener body 1. One end of the fastener body 1 is provided with a strap-passing loop 101 with a strap-passing opening. A limiting groove 102 is arranged inside the fastener body 1. The end of the limiting groove 102 far from the strap-passing loop 101 is stepped. A limiting plate 2 is connected inside the limiting groove 102 near the strap-passing loop 101. The limiting plate 2 is connected to the fastener body 1 through a connecting component 3. The end of the limiting plate 2 connected by the connecting component 3 rotates as the rotation center to form an opening 5 for the guitar tailpin to pass through. A recessed part 201 is arranged at the end of the limiting plate 2 far from the connecting component 3. The recessed part 201 and the end of the limiting groove 102 far from the strap-passing loop 101 form a fitting space 4 for fitting outside the guitar tailpin to realize the connection between the fastener body 1 and the guitar tailpin. The cross-sectional shape of the end of the limiting groove 102 near the strap-passing loop 101 is the same as that of the part near the opening 5 on the other end.
[0028] It should be noted that when the safety buckle is installed on the guitar endpin, the end with the larger cross-sectional shape of the limiting groove 102 of the safety buckle is pressed against the end of the guitar endpin. During the process of the safety buckle being pressed against the end of the guitar endpin, the limiting plate 2 will be squeezed on the guitar endpin, causing the opening 5 formed by the flipping of the limiting plate 2 and the limiting groove 102 to form enough space for the end of the guitar endpin to enter the fitting space 4. After the safety buckle enters the fitting space 4, a connection is formed between the safety buckle and the guitar endpin. However, due to the overly large volume of the end of the guitar endpin, the guitar endpin entering the fitting space 4 is restricted by the limiting plate 2. Under the action of the connection assembly 3, the part where the recessed portion 201 is located presses on the stepped surface of the limiting groove 102 and cannot flip up to form the opening 5 by itself, so that the guitar endpin can only slide within the limiting groove 102 outside the recessed portion 201 and cannot disengage from the limiting groove 102. Then, the guitar strap (not shown in the figure) is threaded into the strap opening of the strap loop 101, thereby realizing the connection of the guitar strap to the guitar endpin, and the operation is simple. When removing the safety buckle from the guitar endpin, the safety buckle is moved to the position of the guitar endpin where the fitting space 4 is away from the recessed portion 201, so that enough space is formed outside the recessed portion 201 for the limiting plate 2 to flip up. Then, the limiting plate 2 is flipped up to enlarge the opening 5, and the opening 5 and the limiting groove 102 form enough space for the end of the guitar endpin to pass through, and the safety buckle can be removed from the guitar endpin, thus realizing the quick connection and disconnection between the safety buckle and the guitar endpin.
[0029] As a further preference of the above embodiment, as Figures 6 - 8 Combined with the figure shown, the connection assembly 3 includes a connecting shaft 301, a torsion spring 302 and an end cap 303. One end of the limiting plate 2 is provided with a connecting portion 202 protruding outside the limiting plate 2. The connecting shaft 301 is in through-fit with the through-hole 203 in the middle of the connecting portion 202. The two side wall surfaces of the fastener body 1 close to the connecting portion 202 are provided with fitting holes 103. The two ends of the connecting shaft 301 are connected to the fastener body 1 through the end caps 303 fitted in the fitting holes 103. The fastener body 1 outside the two sides of the limiting groove 102 is provided with an inner cavity 104, and a torsion spring 302 located in the inner cavity 104 is sleeved on the part of the connecting shaft 301 between the connecting portion 202 and the end cap 303.
[0030] Among them, the connection between the limiting plate 2 and the fastener body 1 is realized through the cooperation of the connecting shaft 301 and the end cover 303. The limiting plate 2 uses the connecting shaft 301 to achieve the purpose of rotating with one end as the rotation center. Thus, when the safety buckle is installed on the guitar tail pin, the limiting plate 2 will be squeezed by the guitar tail pin and rotate and turn up in the direction away from the limiting groove 102 with the end where the connecting shaft 301 is located; during the process of the limiting plate 2 turning up, it is necessary to overcome the elastic recovery effect of the torsion spring 302. After the guitar tail pin enters the fitting space 4, the elastic recovery effect of the torsion spring 302 makes the limiting plate 2 swing back in the direction close to the limiting groove 102, and the recessed part 201 of the limiting plate 2 presses on the stepped limiting groove 102, thereby buckling the safety buckle outside the guitar tail pin; when removing the safety buckle from the guitar tail pin, the operator only needs to turn up the limiting plate 2 by overcoming the elastic recovery effect of the torsion spring 302 to form enough space between the opening 5 and the limiting groove 102, then the safety buckle can be removed from the guitar tail pin, and the operation is simple and convenient.
[0031] Preferably, as Figure 7 and Figure 8 Combined as shown, on the wall surface of the fastener body 1 outside the inner cavity 104, there is a groove 105. On both sides of the middle part of the limiting plate 2, there are shaft posts 204 fitted in the groove 105. The two feet 304 of the torsion spring 302 extend in the same direction into the space of the inner cavity 104 close to the outside of the shaft post 204, and one of the feet 304 presses on the surface of the shaft post 204.
[0032] Among them, during the process of the limiting plate 2 turning up, the feet 304 of the two torsion springs 302 extend into the space of the inner cavity 104 close to the outside of the shaft post 204, and one of the feet 304 of the torsion spring 302 presses on the surface of the shaft post 204 of the limiting plate 2, which is equivalent to increasing the force arm to make it more labor-saving and more convenient to turn up the limiting plate 2.
[0033] For a further preference of the above preferred solution, as Figure 9 shown, on the end wall surface of the inner cavity 104 away from the connecting shaft 301 and the groove 105 side, there is a first limiting block 106. One of the feet 304 of the torsion spring 302 extends into the space of the inner cavity 104 outside the first limiting block 106. At the end of the shaft post 204 away from the limiting plate 2, there is a second limiting block 107. The other foot 304 of the torsion spring 302 extends into the space of the inner cavity 104 outside the second limiting block 107.
[0034] Among them, since the torsion spring 302 needs to be twisted by the contact between the pin 304 and the wall of the inner cavity 104 when the limit plate 2 rotates, so as to form an elastic restoring force to reverse the rotation of the limit plate 2, the contact between the pin 304 and the wall of the inner cavity 104 is easy to form a sliding contact when the torsion spring 302 is twisted, and when the torsion spring 302 is connected to the connecting shaft 301 between the end cover 303 and the connecting part 202, the entire torsion spring 302 may not be able to completely cover the end cover 303 and the connecting part 202. In addition to the connecting shaft 301 between the connecting parts 202, the torsion spring 302 will slide between the end cover 303 and the connecting part 202 when the limiting plate 2 rotates. The above two situations will cause the pin 304 to deviate from the inner cavity 104 and the torsion spring 302 cannot be deformed. The first limiting block 106 can limit one of the pins 304 of the torsion spring 302, and the second limiting block 107 can limit the other pin 304, thereby preventing the two pins 304 from deviating from the inner cavity 104.
[0035] As a further preference of the above embodiment, Figure 10 and Figure 11 As shown in combination, the end wall of the limiting plate 2 at the opening 5 is provided with a protrusion 205, the cross-sectional shape of the protrusion 205 in the vertical direction is triangular, and the cross-sectional shape of the end of the protrusion 205 near the opening 5 is the same as the cross-sectional shape of the end of the limiting plate 2 near the opening 5.
[0036] Among them, when the limiting plate 2 is flipped up to form the opening 5 and the guitar tail nail moves from the end with a larger cross-sectional area of the opening 5 and the limiting groove 102 to the end with a stepped shape, since the limiting plate 2 needs to contact the end of the guitar tail nail, the protrusion 205 will guide through its inclined surface, so that the end of the guitar tail nail can move toward the opening 5 side along the inclined surface on the protrusion 205, making the action of pressing the safety buckle from the end of the guitar tail nail smoother.
[0037] As a further preference of the above embodiment, Figure 11 As shown, a paddle 206 is provided on the end surface of the limit plate 2 away from the connecting component 3. The cross-sectional shape of the paddle 206 is a broken line and extends obliquely in a direction away from the connecting component 3. An accommodating space 207 for a finger force point is formed between the paddle 206 and the limit plate 2.
[0038] When removing the safety buckle from the guitar tail nail, the operator can put his fingers into the accommodating space 207 to form a fulcrum on the pick 206, which makes it convenient for the operator to pull the pick 206 to pull the limiting plate 2 to flip up in a direction away from the limiting groove 102.
[0039] As a further preference of the above embodiment, Figure 1As shown, anti-slip patterns 108 are provided on the outer walls on both sides of the fastener body 1.
[0040] Among them, when the safety fastener is installed on or removed from the guitar endpin, the anti-slip patterns 108 can facilitate the operator to pick up the fastener body 1 and make the convenient operation more stable.
[0041] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
