Description

Technical Field

[0001] This utility model belongs to the technical field of strap connectors, and relates to a quick-release buckle connector for musical instrument straps. Background Technology

[0002] Strap buckles are widely used connectors in musical instrument straps, bags, and safety equipment. Currently, common strap connectors on the market can be mainly divided into the following two categories:

[0003] 1. Ordinary leather strap buckles have a simple structure, with holes drilled in the leather strap or metal rings set in the leather strap to form a strap buckle. The strap buckle is fastened to the strap pins on the instrument. When the instrument is used or the contact area is subjected to severe vibration, pulling or impact, the strap buckle on the strap is easy to come off the strap pins due to the lack of locking force, which can lead to connection failure, falling and damaging the instrument, posing a significant safety hazard.

[0004] 2. Manual locking buckles on the market use a slider on the buckle body, which requires the user to actively slide to unlock. The locking structure is complex, with more parts, and the unlocking operation is troublesome. In case of emergency, it is difficult to unlock and separate quickly.

[0005] Therefore, there is an urgent need in this field for a self-locking strap buckle that is structurally sound, has a reliable locking mechanism, and is easy to operate. Utility Model Content

[0006] This utility model provides a quick-release buckle connector for musical instrument straps, aiming to solve the problems of existing musical instrument strap connectors having complex structures, unreliable buckles that are easy to fall off, and inconvenient operation for unfastening.

[0007] To achieve the above objectives, this utility model provides a quick-release locking connector for musical instrument straps, including a insert hanger and a locking plate. The locking plate is placed on the insert hanger. One side of the insert hanger is elastically connected to one side of the locking plate. The other side of the insert hanger has a connecting hole. The middle of the insert hanger has a U-shaped groove that communicates with the connecting hole. The locking plate has a locking hole, and one inner wall of the locking hole is located at the position where the U-shaped groove and the connecting hole communicate.

[0008] Preferably, a pin is provided between the side end of the insert and the lock plate, and a torsion spring is provided in the middle of the pin, with the two ends of the torsion spring abutting against the inner sides of the insert and the lock plate respectively.

[0009] Preferably, the locking plate has a pressing part near the pin.

[0010] Preferably, an extended boss is integrally connected to the other side of the locking plate, and the extended boss is movable within the connecting hole.

[0011] Preferably, a rubber pad is attached to the back of the insert holder.

[0012] The advantages of this utility model over the prior art are:

[0013] This utility model provides a quick-release locking connector for musical instrument straps, which is used to attach to mushroom-shaped nails. First, the connector enters through the connecting hole on the insert body, lifting the outer protrusion. The torsion spring is compressed. Continuing to slide, the insert body enters the U-shaped slot and disengages from the outer protrusion into the locking hole, forming a locking state using the U-shaped slot and the locking hole. Pressing down on the pressing part creates an escape angle between the insert body and the locking plate. Reverse sliding causes the insert body to disengage from the U-shaped slot and emerge from the connecting hole, thus releasing the strap. The entire structure is simple, allowing for quick locking and unlocking, easy operation, and effectively preventing the strap from falling off and damaging the instrument.

[0014] To more clearly illustrate the structural features and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0023] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0024] To achieve the above objectives, this utility model provides a quick-release locking connector for musical instrument straps, see reference. Figure 1-5 As shown, it includes a insert hanger 1 and a locking plate 2. The locking plate 2 is placed on the insert hanger 1. One side of the insert hanger 1 is connected to one side of the locking plate 2 by an elastic shaft. The other side of the insert hanger 1 is provided with a connecting hole 12. The middle of the insert hanger 1 is provided with a U-shaped slot 11, which is connected to the connecting hole 12. The locking plate 2 is provided with a locking hole 23. One side of the inner wall of the locking hole 23 is located at the position where the U-shaped slot 11 and the connecting hole 12 are connected.

[0025] Existing musical instruments (taking guitar as an example) are equipped with a strap. Two mushroom-shaped pins 5 are fixedly installed on the top and bottom of the guitar body. The traditional connection between the strap and the mushroom-shaped pins is a hard-press connection. Disassembly also requires external force to bend them apart, which can easily damage the mushroom-shaped pins 5. The manual unlocking method using a sliding rail slider is complex in structure, troublesome in operation, and difficult to separate quickly. In this embodiment, the outer diameter of the head of the mushroom nail 5 is larger than the inner size of the U-shaped slot 11 and smaller than the inner size of the locking hole 23. The outer diameter of the shaft of the mushroom nail 5 is smaller than the inner size of the U-shaped slot 11. In this way, the shaft of the mushroom nail 5 can move into the U-shaped slot 11, and the head of the mushroom nail 5 will hang on the U-shaped slot 11. Since one side of the inner wall of the locking hole 23 is located at the through position of the U-shaped slot 11 and the connecting hole 12, the locking hole 23 can prevent the head of the mushroom nail 5 from coming out of the U-shaped slot 11. In this way, the entire mushroom nail 5 is locked and connected to form a stable lock. Of course, one end of the strap passes through the connecting hole 12 and connects with the insert hanging body 1, which will not affect the mushroom nail 5 from being fitted into the connecting hole 12.

[0026] Specifically, a pin 3 passes through the side end of the insert hanger 1 and the locking plate 2. A torsion spring 4 passes through the middle of the pin 3. The two ends of the torsion spring 4 are respectively pressed against the inner side of the insert hanger 1 and the locking plate 2 to facilitate the automatic reset of the locking plate 2. A pressing part 22 is provided near the pin 3 on the locking plate 2. An extended boss 21 is integrally connected to the other side of the locking plate 2. The extended boss 21 is movable in the connecting hole 12. The addition of the extended boss 21 can increase the structural area of ​​the edge of the locking plate 2 and the extended boss 21 in the connecting hole 12. The extended boss 21 is preferably trapezoidal in shape. In the locked state of the locking plate 2, there is a gap between the outer wall of the extended boss 21 and the inner wall of the connecting hole 12. However, the gap is much smaller than the head of the mushroom nail 5, so that the head of the mushroom nail 5 can accurately hit the edge of the locking plate 2 and the position of the extended boss 21 each time it enters the connecting hole 12, and quickly engage. A rubber pad 6 is attached to the back of the insert hanger 1.

[0027] Locking process:

[0028] When it is necessary to connect the shoulder strap, hold the insert bracket 1 and push the insert bracket 1 along the connecting hole 12 of the lock plate 2 until it contacts the mushroom pin 5. Figure 1 (The dotted circular part) The head of the mushroom nail 5 first contacts the edge of the locking plate 2 and the outer protrusion 21. As the insert hanger 1 continues to advance, the head of the mushroom nail 5 squeezes the edge of the locking plate 2 and the outer protrusion 21, forcing the locking plate 2 to overcome the elastic force of the torsion spring 4 and rotate upward around the pin 3. The insert hanger 1 and the locking plate 2 form a certain angle (e.g., Figure 1 As shown), space is made for the insertion of the mushroom nail 5. The insert bracket 1 is then pushed forward, allowing the mushroom nail 5 to enter along the U-shaped slot 11. When the shaft of the mushroom nail 5 is inserted to the designated depth in the U-shaped slot 11, the head of the mushroom nail 5 just moves into the locking hole 23. The locking plate 2 is not subjected to any upward force. Under the action of the torsion spring 4, the locking plate 2 will quickly press down along the pin 3, producing a "click" sound. At this time, the angle between the insert bracket 1 and the locking plate 2 is zero (as shown). Figure 3 As shown), the mushroom-shaped nail 5 is mechanically locked in the U-shaped slot 11 and locking hole 23 and cannot be pulled out, thus achieving a reliable connection of the mushroom-shaped nail 5. Figure 5 (The dotted circle section) completes the strap locking of mushroom stud 5.

[0029] Unlocking process:

[0030] When disconnection is required, press down on the pressing part 22 of the locking plate 2 with your finger, causing the locking plate 2 to rotate upward against the elastic force of the torsion spring 4. The insert bracket 1 forms a certain angle with the locking plate 2. Push the insert bracket 1 so that the U-shaped slot 11 moves away from the rod of the mushroom nail 5, and the head of the mushroom nail 5 will disengage from the locking hole 23. Continue to push it so that the head of the mushroom nail 5 is located below the edge of the locking plate 2 and the outer protrusion 21. At this time, the mushroom nail 5 is located in the connection hole 12. Continue to press down on the pressing part 22, and the mushroom nail 5 can be easily disengaged from the connection hole 12, achieving quick unlocking (see...). Figure 1 Once the pressing part 22 is released, under the action of the torsion spring 4, the angle between the insert hanging body 1 and the locking plate 2 is zero, and it returns to the natural waiting position.

[0031] In summary, this utility model provides a quick-release locking connector for musical instrument straps. The connector is connected to the mushroom-shaped nail 5. First, the insert pendant 1 enters the extended boss 21 through the connecting hole 12 on the insert pendant 1, and the torsion spring 4 is in a compressed state. Continuing to slide the insert pendant 1, it will enter the U-shaped slot 11 and disengage from the extended boss 21 to enter the locking hole 23. The U-shaped slot 11 and the locking hole 23 form a locking state. Pressing down the pressing part 22 causes the insert pendant 1 to form an escape angle with the locking plate 2. Sliding in the opposite direction, the insert pendant 1 will disengage from the U-shaped slot 11 and come out from the connecting hole 12, forming an unfastened state. The whole structure is simple, can realize quick locking and unlocking, is easy to operate, and effectively prevents the strap from falling off and damaging the instrument.

[0032] Of course, this embodiment can be used on musical instrument straps, and can also be used on other items such as bags, safety protective equipment, etc.
