Description

Technical Field

[0001] This application relates to the field of musical instrument technology, and more specifically, to a strap buckle and a strap. Background Technology

[0002] Many musical instruments, such as guitars and basses, typically have strap pins mounted on the instrument and strap buckles on the strap. The strap pins pass through the strap buckles to secure and carry the instrument. However, in these technologies, the mounting holes on the strap buckles for engaging with the guitar tailpiece are usually of a fixed size, causing significant inconvenience for users in assembling and removing the straps. Utility Model Content

[0003] This application provides a strap buckle and a strap to solve at least one of the above-mentioned technical problems.

[0004] The strap buckle of this application embodiment is used to connect with the strap pin, including:

[0005] The housing has a mounting hole formed on its inner side and a mounting cavity formed inside;

[0006] Two engaging components are provided, each including an engaging member and an elastic member. The engaging member includes a snap-fit ​​side and a connecting side opposite to the snap-fit ​​side. The two engaging members are slidably disposed in the mounting cavity. The two snap-fit ​​sides extend into the mounting hole and form snap-fit ​​grooves for engaging the strap studs. The elastic member connects the corresponding connecting side and the sidewall of the mounting cavity. The snap-fit ​​side is provided with a guide surface inclined toward the snap-fit ​​groove, and the guide surface is at least partially located in the mounting hole.

[0007] Two unlocking components, each comprising a button side and an actuating side opposite to the button side, are slidably disposed in the mounting cavity. The button side protrudes from the outer side wall of the housing, and the actuating side is coupled to the engaging component. When the two unlocking components are pressed into the mounting cavity, they push the two engaging components away from each other against the elastic force of the elastic element, thereby widening the engaging groove and allowing the strap pin to disengage from the engaging groove.

[0008] The strap buckle provided in this application allows for easy connection between the strap buckle and the strap pin. Simply attach the buckle's mounting hole to the strap pin and press it inward. The strap pin will then press against the guide surface and slide along it. At this point, the two locking parts will overcome the elastic force of the elastic element and slide away from each other under the push of the strap pin, thereby opening the locking groove and allowing the strap pin to enter the locking groove. When disassembly is required, simply press the two unlocking parts to disengage the strap pin from the locking groove, thus reducing the difficulty of assembling and disassembling the strap pin and the strap buckle.

[0009] In some embodiments, the housing includes a bottom shell and a top cover, the bottom shell forming a mounting groove, the engaging assembly and the unlocking element being disposed within the mounting groove, and the top cover being fixedly disposed on the bottom shell and closing the mounting groove to form the mounting cavity.

[0010] Thus, the housing is divided into two parts: a bottom shell and a top cover, which facilitates the installation of the locking and unlocking components.

[0011] In some embodiments, the bottom shell forms a first slide rail and a second slide rail on the bottom surface of the mounting groove. The engaging member is slidably disposed in the mounting cavity via the first slide rail, and the unlocking member is slidably disposed in the mounting cavity via the second slide rail. The guide of the first slide rail is substantially perpendicular to the guide of the second slide rail.

[0012] Thus, the first and second slide rails are set vertically, which facilitates the arrangement of the locking and unlocking components and helps to optimize the space occupied in the installation cavity.

[0013] In some embodiments, the first slide rail includes a first segment, the bottom shell includes an elastic element seat disposed on one side of the bottom shell and first limiting ribs located on both sides of the elastic element seat, the elastic element seat and the first limiting ribs defining the first segment, and the engaging member includes a limiting strip located on the engaging side, the limiting strip being slidably embedded in the first segment.

[0014] Thus, the elastic element holder can be used to connect the elastic element and also to limit the first slide rail, realizing the dual function of the elastic element holder.

[0015] In some embodiments, the bottom shell includes two second defining ribs disposed on one side of the bottom shell, the two second defining ribs defining the second slide rail, and the actuating side being slidably embedded in the second slide rail.

[0016] Thus, by defining the second slide rail with two second limiting ribs and using it to slide the unlocking component, the connection structure between the unlocking component and the housing is simplified.

[0017] In some embodiments, the first slide rail includes a second segment connected to the first segment, the bottom shell includes four third limiting ribs, the third limiting ribs are connected to the corresponding second limiting ribs at the ends away from the outer side wall to limit the sliding range of the unlocking member, two third limiting ribs located on the same side of the mounting hole are arranged opposite to each other, two third limiting ribs located on opposite sides of the mounting hole define the second segment, and the buckle side is slidably embedded in the second segment.

[0018] Thus, the third limiting rib is used not only to limit the sliding range of the unlocking component, but also to limit the sliding direction of the buckle side, realizing the multi-purpose function of the third limiting rib.

[0019] In some embodiments, the strap buckle further includes a silicone pad that is attached to the outer surface of the bottom shell.

[0020] In this way, the silicone pad can isolate the strap buckle from the instrument body, preventing the strap buckle from colliding with the instrument due to vibration during performance, thus avoiding abnormal noise.

[0021] In some embodiments, the actuating side is provided with two first inclined surfaces opposite to the button side, the first inclined surfaces being substantially parallel to the axis of the mounting hole, and the two first inclined surfaces forming an outwardly projecting angle. The latching side includes two second inclined surfaces opposite to each other, the second inclined surfaces pressing against adjacent first inclined surfaces and being substantially parallel to adjacent first inclined surfaces. The engaging member is configured such that when the button side is pressed into the housing, the first inclined surfaces push the second inclined surfaces to slide the engaging member, thereby expanding the latching groove.

[0022] In this way, by using the first and second inclined surfaces in combination to push the latching side from the action side, the wear on the action side and the latching side can be reduced. At the same time, it can simplify the structure of the engaging and disengaging parts and reduce the difficulty of processing.

[0023] In some embodiments, the snap-fit ​​side is provided with an inwardly recessed arc surface, and the arc surfaces of the two snap-fit ​​sides are arranged opposite to each other.

[0024] In this way, using two opposing arc surfaces to fix the strap pins helps to make the strap buckle more stable.

[0025] Another embodiment of the strap in this application includes the strap buckle described in any of the above claims.

[0026] Additional aspects and advantages of embodiments of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of embodiments of this application. Attached Figure Description

[0039] Many musical instruments, such as guitars and basses, typically have strap pins attached to the instrument and U-shaped strap buckles on the strap. The strap pins pass through the strap buckles to secure and carry the instrument. However, this method of securing the strap can easily cause the connection between the strap pins and the strap buckles to detach when the player moves significantly, thus affecting the quality of the performance and potentially damaging the instrument.

[0040] Please see Figure 1This application provides a shoulder strap, including a shoulder strap buckle 100. The shoulder strap buckle 100 includes a housing 10, two engaging components 20, and two unlocking components 30. The housing 10 has a mounting hole 13 on its inner side and a mounting cavity 14 inside. The engaging components 20 include engaging members 21 and elastic members 22. The engaging members 21 include a buckling side 211 and a connecting side 212 opposite to the buckling side 211. The two engaging members 21 are slidably disposed in the mounting cavity 14. The two buckling sides 211 extend into the mounting hole 13 and form engaging grooves 323 for engaging shoulder strap studs 200. The elastic members 22 connect the corresponding connecting side 212 and the side of the mounting cavity 14. The wall, the buckle side 211 is provided with a guide surface 2114 inclined towards the snap-fit ​​groove 323, the guide surface 2114 is at least partially located in the mounting hole 13; the unlocking member 30 includes a button side 31 and an action side 32 opposite to the button side 31, the two unlocking members 30 are slidably disposed in the mounting cavity 14, the button side 31 protrudes from the outer side wall of the housing 10, and the action side 32 is coupled with the snap-fit ​​member 21; when the two unlocking members 30 are pressed into the mounting cavity 14, the two unlocking members 30 push the two snap-fit ​​members 21 to overcome the elastic force of the elastic member 22 and slide away from each other, so as to expand the snap-fit ​​groove 323 and allow the strap pin 200 to disengage from the snap-fit ​​groove 323.

[0041] The strap buckle 100 provided in this application, when it is necessary to connect the strap buckle 100 and the strap pin 200, only needs to fasten the mounting hole 13 of the strap buckle 100 onto the strap pin 200 and press it inward. The strap pin 200 can then press against the guide surface 2114 and slide along the guide surface 2114. At this time, the two locking parts 21 will overcome the elastic force of the elastic part 22 and slide away from each other under the push of the strap pin 200, thereby opening the locking groove 323 and allowing the strap pin 200 to enter the locking groove 323. When it is necessary to disassemble, only the two unlocking parts 30 need to be pressed to make the strap pin 200 disengage from the locking groove 323, which reduces the difficulty of disassembling and assembling the strap pin 200 and the strap buckle 100.

[0042] Specifically, stringed instruments such as electric guitars, basses, acoustic guitars, violins, violas, cellos, and some wind instruments such as certain models of saxophones typically include a strap and strap pins 200. The strap supports the weight of the instrument, reducing strain on the player's arms and shoulders, allowing for easier playing. Strap pins 200 are accessories used to secure the strap. They are usually installed at the neck and bottom (or sides) of the instrument to firmly attach the strap. In this embodiment, a guitar is used as an example instrument.

[0043] In this embodiment, two sets of engaging components 20 and two sets of unlocking components 30 are arranged at intervals around the mounting hole 13, and the sliding direction of the engaging components 20 is perpendicular to the sliding direction of the unlocking components 30. Openings 15 are provided on opposite sides of the outer wall of the housing 10, and the button side 31 of the unlocking component 30 extends from the outer wall through the opening 15.

[0044] Furthermore, the side wall of the mounting hole 13 is provided with an annular groove, and the mounting cavity 14 is connected to the mounting hole 13 through the annular groove. The snap-fit ​​side 211 of the snap-fit ​​part 21 extends into the mounting hole 13 from the annular groove.

[0045] Please see Figure 2 In this embodiment of the application, the strap nail 200 includes a fixed end 210, a connecting section 220 and a top end 230. The fixed end 210 is used to attach to the outer surface of the instrument and connect to the instrument. One end of the connecting section 220 is connected to the fixed end 210 and the other end is connected to the top end 230. The fixed end 210, the connecting section 220 and the top end 230 are generally cylindrical. The diameters of the fixed end 210 and the top end 230 are basically the same, and the diameter of the connecting section 220 is smaller than that of the fixed end 210 and the top end 230.

[0046] In other embodiments, the diameter of the fixed end 210 may be smaller than the diameter of the top end 230 but larger than the diameter of the connecting section 220.

[0047] Please see Figure 1 Furthermore, when the strap buckle 100 is connected to the strap pin 200, the snap-fit ​​groove 323 snaps into the connecting section 220. That is, the width of the snap-fit ​​groove 323 is greater than or equal to the diameter of the connecting section 220, but less than the diameter of the fixed end 210 and the top end 230.

[0048] Furthermore, the guide surface 2114 is a conical surface, so that the thickness of the buckle side 211 gradually decreases from the end near the connecting side 212 to the end away from the connecting side 212. The thickness of the end away from the connecting side 212 is less than or equal to the thickness of the connecting section 220, thereby providing an inclination to assist the strap pin 200 to directly enter the strap buckle 100 without other operations.

[0049] The connecting side 212 is a columnar structure arranged along the sliding direction of the engaging member 21. The elastic member 22 is a columnar spring, with one end of the spring connected to the inner wall of the mounting cavity 14 and the other end sleeved on the connecting side 212.

[0050] Please see Figure 3 In some embodiments, the housing 10 includes a bottom shell 11 and a top cover 12. The bottom shell 11 forms a mounting groove, and the engaging assembly 20 and the unlocking member 30 are disposed in the mounting groove. The top cover 12 is fixedly disposed on the bottom shell 11 and closes the mounting groove to form a mounting cavity 14.

[0051] Thus, the housing 10 is divided into two parts: the bottom shell 11 and the top cover 12, which facilitates the installation of the locking assembly 20 and the unlocking component 30.

[0052] Specifically, in this embodiment, the bottom shell 11 is in the shape of an annular groove, the top cover 12 is in the shape of a plate, the bottom shell 11 is detachably connected to the top cover 12 by fasteners, and a mounting hole 13 is formed in the middle of the bottom shell 11. The bottom shell 11 and the top cover 12 enclose each other to form a mounting groove.

[0053] Furthermore, a first groove 111 is provided on each of the opposite sides of the outer side wall of the bottom shell 11, and a second groove 121 is provided on the top cover 12 corresponding to the first groove 111. The first groove 111 and the second groove 121 are joined together to form an opening 15 for the pusher to pass through.

[0054] In this embodiment of the application, the unlocking member 30 is M-shaped, and the unlocking member 30 is provided with limiting parts 322 on both sides. When the card is in the initial position, the limiting parts 322 abut against the inner edge of the opening 15, so that the unlocking member 30 can be dislodged from the opening 15.

[0055] Please see Figure 1 and Figure 4 In some embodiments, the bottom shell 11 forms a first slide rail 112 and a second slide rail 113 on the bottom surface of the mounting groove. The engaging member 21 is slidably disposed in the mounting cavity 14 via the first slide rail 112, and the unlocking member 30 is slidably disposed in the mounting cavity 14 via the second slide rail 113. The guide of the first slide rail 112 is substantially perpendicular to the guide of the second slide rail 113.

[0056] Thus, the first slide rail 112 and the second slide rail 113 are arranged vertically, which facilitates the arrangement of the engaging component 20 and the unlocking component 30 and helps to optimize the space occupied in the mounting cavity 14.

[0057] Specifically, in this embodiment, the first slide rail 112 and the second slide rail 113 are arranged vertically, and the mounting hole 13 is located at the intersection of the first slide rail 112 and the second slide rail 113. When the two unlocking members 30 slide toward the mounting hole 13, they push the two locking members 21 to slide in a direction away from the mounting hole 13.

[0058] In some embodiments, the first slide rail 112 includes a first segment 1121, the bottom shell 11 includes an elastic element seat 114 disposed on one side of the bottom shell 11 and first limiting ribs 115 located on both sides of the elastic element seat 114, the elastic element seat 114 and the first limiting ribs 115 defining the first segment 1121, and the engaging member 21 includes a limiting strip 213 located on the engaging side, the limiting strip 213 being slidably embedded in the first segment 1121.

[0059] Thus, the elastic element seat 114 can be used to connect the elastic element 22 and to limit the first slide rail 112, realizing the dual function of the elastic element seat 114.

[0060] Specifically, in this embodiment of the application, the first slide rail 112 includes a first segment 1121 and a second segment 1122 connected together, wherein the limiting strip 213 is slidably disposed in the first segment 1121 and the engaging side is slidably disposed in the second segment 1122.

[0061] Furthermore, in this embodiment, an elastic element seat 114 is provided in the middle of one side of the bottom shell 11. The elastic element seat 114 is rectangular in shape, and one end of the elastic element 22 can be locked in the elastic element seat 114.

[0062] Furthermore, the bottom shell 11 is also provided with a first limiting rib 115. The first limiting rib 115 is provided from the outer side wall of the bottom shell 11 along the sliding direction of the engaging member 21. There are two first limiting ribs 115 on the same side as the elastic member seat 114. The two first limiting ribs 115 and the two side walls of the elastic member seat 114 respectively enclose to form two first segments 1121 respectively provided on both sides of the elastic member seat 114.

[0063] In this embodiment of the application, the limiting strip 213 is a strip-shaped structure that is provided outward from the locking member 21 along the sliding direction of the locking member 21. There are two limiting strips 213, which are respectively provided on both sides of the connecting side 212 and are slidably embedded in the two first segments 1121.

[0064] In some embodiments, the bottom shell 11 includes two second limiting ribs 116 disposed on one side of the bottom shell 11, the two second limiting ribs 116 defining a second slide rail 113, and the working side 32 being slidably embedded in the second slide rail 113.

[0065] Thus, by defining the second slide rail 113 by the two second limiting ribs 116 and using it to slide the unlocking member 30, it is beneficial to simplify the connection structure between the unlocking member 30 and the housing 10.

[0066] Specifically, in this embodiment, the second limiting rib 116 is a rib-shaped structure. The second limiting rib 116 is arranged from the inner side of the edge of the opening 15 along a direction perpendicular to the first limiting rib 115. There are four second limiting ribs 116, which are respectively arranged on both sides of the mounting hole 13. There are two second limiting ribs 116 on the same side of the mounting hole 13. The two second limiting ribs 116 on the same side of the mounting hole 13 are respectively arranged on both sides of the opening 15. The two second limiting ribs 116 on the same side of the mounting hole 13 enclose to form a second slide rail 113. The working side 32 is slidably embedded in the second slide rail 113.

[0067] In some embodiments, the first slide rail 112 includes a second segment 1122 connected to the first segment 1121, and the bottom shell 11 includes four third limiting ribs 117. The third limiting ribs 117 are connected to the corresponding second limiting ribs 116 at the ends away from the outer side wall to limit the sliding range of the unlocking member 30. Two third limiting ribs 117 located on the same side of the mounting hole 13 are arranged opposite to each other, and two third limiting ribs 117 located on opposite sides of the mounting hole 13 define the second segment 1122. The snap-fit ​​side 211 is slidably embedded in the second segment 1122.

[0068] Thus, the third limiting rib 117 is used not only to limit the sliding range of the unlocking part 30, but also to limit the sliding direction of the buckle side 211, realizing the multi-purpose function of the third limiting rib 117.

[0069] Specifically, in this embodiment, the third limiting rib 117 is a rib-shaped structure. The third limiting rib 117 is arranged from the edge of the second limiting rib 116 away from the opening 15 inward along a direction perpendicular to the second limiting rib 116. There are four third limiting ribs 117, which are respectively arranged on both sides of the mounting hole 13. There are two third limiting ribs 117 on the same side of the mounting hole 13. The two second limiting ribs 116 on the same side of the mounting hole 13 are respectively arranged on both sides of the opening 15 and in opposite directions. The two third limiting ribs 117 on the same side of the mounting hole 13 enclose to form the second slide rail 113, and the snap-fit ​​side 211 is slidably embedded in the third slide rail.

[0070] Please see Figure 5 In some embodiments, the strap buckle 100 also includes a silicone pad 40, which is attached to the outer surface of the bottom shell 11.

[0071] In this way, the silicone pad 40 can isolate the strap buckle 100 from the instrument body, preventing the strap buckle 100 from colliding with the instrument due to vibration during performance, thus avoiding abnormal noise.

[0072] Specifically, in this embodiment, the silicone pad 40 is arranged in a ring around the mounting hole 13. A mounting groove is provided on the outer surface of the bottom shell 11, and the silicone pad 40 is disposed within the silicone pad 40.

[0073] In some embodiments, the silicone pad 40 may also be made of other materials, such as foam or rubber, depending on the actual needs. This will not be elaborated further here.

[0074] In this embodiment, the silicone pad 40 is adhesively attached to the outer surface of the bottom shell 11. In other embodiments, the silicone pad 40 and the bottom shell 11 can be connected by a detachable fastener.

[0075] Please see Figure 1 and Figure 6 In some embodiments, the action side 32 is provided with two first inclined surfaces 321 opposite to the button side 31. The first inclined surfaces 321 are substantially parallel to the axis of the mounting hole 13. The two first inclined surfaces 321 form an outwardly protruding included angle. The latching side 211 includes two second inclined surfaces 2112 opposite to each other. The second inclined surfaces 2112 press against the adjacent first inclined surfaces 321 and are substantially parallel to the adjacent first inclined surfaces 321. The engaging member 21 is configured such that when the button side 31 is pressed into the housing 10, the first inclined surfaces 321 push the second inclined surfaces 2112 to make the engaging member 21 slide, thereby expanding the latching groove 323.

[0076] Thus, by using the first inclined surface 321 and the second inclined surface 2112 in cooperation to enable the action side 32 to push the latching side 211, it is beneficial to reduce the wear of the action side 32 and the latching side 211, and at the same time, it is beneficial to simplify the structure of the engaging part 21 and the unlocking part 30 and reduce the processing difficulty.

[0077] Specifically, in this embodiment, the first inclined surface 321 and the second inclined surface 2112 are both perpendicular to the bottom surface of the bottom shell 11. The two first inclined surfaces 321 are arranged opposite each other on the working side 32 to form a 90° angle, and the corresponding second inclined surface 2112 is parallel to the first inclined surface 321.

[0078] In this embodiment of the application, when the two unlocking members 30 are pressed inward, the first inclined surface 321 presses against the second inclined surface 2112 and moves toward the mounting hole 13. Under the push of the first inclined surface 321, the second inclined surface 2112 drives the locking member 21 to move away from the mounting hole 13 along the direction perpendicular to the moving direction of the unlocking member 30.

[0079] In this embodiment, the engaging side is further provided with two pushing parts 2111, which are respectively provided on both sides of the engaging side. The second inclined surface 2112 is provided at the end of the pushing part 2111 away from the engaging side. The pushing part 2111 extends into the second slide rail 113 from between the two third limiting ribs 117 and presses against the first inclined surface 321 of the action side 32. When the unlocking member 30 presses inward to the end point, the pushing part 2111 slides along the direction of the first slide rail 112 to press against the third limiting rib 117.

[0080] In some embodiments, the snap-fit ​​side 211 is provided with an inwardly recessed arc surface 2113, and the arc surfaces 2113 of the two snap-fit ​​sides 211 are arranged opposite to each other.

[0081] In this way, using two opposing arc surfaces 2113 to fix the strap pins 200 helps to make the strap buckle 100 more stable.
