Snare wires adjustment device

Abstract

The present invention relates to a resonant adjustment device, comprising: a supporting body, a movable body, a sling connecting body, an opening and closing body, and a resonant mechanism. The movable body is movably connected to the supporting body, and the sling connecting body is connected to the movable body and has a hook portion and a contact portion. The opening and closing body can drive the movable body to move relative to the supporting body, so that the sling connecting body can move synchronously with the movable body. The two slings of the resonant mechanism are respectively connected to opposite sides of the resonant assembly of the resonant mechanism, and the slings cross the contact portion to hook onto the hook portion, so that the hooking space of the hook portion can accommodate a portion of the sling, and the other portion of the sling can simultaneously contact the contact portion. In this way, the resonant mechanism can be connected and disconnected from the sling connecting body without any hand tools, and the user can quickly disconnect the resonant mechanism from the sling connecting body by hand.

Claims

1. A reed adjustment device, comprising: a reed mechanism having a reed assembly and two straps connected to the reed assembly; and an adjustment mechanism comprising: a support body connected to a drum shell; a movable body movably connected to the support body, such that the movable body can move relative to the support body; and a strap connecting body capable of moving synchronously with the movable body, and having a hook portion and a contact portion, the hook portion forming a hooking space, wherein... The aforementioned sling connection body has a sling connection seat and a sling connection wheel. The sling connection seat is recessed to form two connection grooves, which are used to accommodate a portion of the sling, allowing a portion of the sling to contact the wall of the connection groove to form a contact portion. The sling connection wheel has a connection wheel shaft portion near the sling connection seat and a connection wheel portion away from the sling connection seat, and a hooking space is formed between the connection wheel shaft portion and the connection wheel portion, allowing the sling connection wheel to form a hook portion. It also includes an opening and closing body that can drive the movable body to move. The sling can cross the contact portion from the cord assembly and hook onto the hook portion, allowing the hooking space to accommodate a portion of the sling, and allowing another portion of the sling to simultaneously contact the contact portion.

2. The cord adjustment device as described in claim 1, wherein, The aforementioned sling connecting wheel is located between the two connecting grooves, and the height of the aforementioned sling connecting wheel at its highest point is lower than the height of the aforementioned connecting groove.

3. The cord adjustment device as described in claim 1, wherein, The aforementioned sling connection body further includes a sling pressure plate, a pressure plate screw, and a connecting wheel connector. A screw rod of the pressure plate screw passes through the sling pressure plate to connect to the sling connection seat, such that a screw head of the pressure plate screw and the sling connection seat are clamped together in the sling pressure plate. The sling pressure plate has a recessed pressure plate space on the side facing the sling connection seat. The connecting wheel connector has a connecting head located inside the pressure plate space and a connecting rod formed at one end of the connecting head. The connecting rod is located outside the pressure plate space and connects to the connecting wheel shaft.

4. The cord adjustment device as described in claim 3, wherein, The aforementioned sling connector has a first fixed seat surface that contacts the aforementioned sling pressure plate and a second fixed seat surface that forms the aforementioned connecting groove. The aforementioned connecting groove has a first turning surface adjacent to the aforementioned first fixed seat surface and a groove bottom surface spaced below the aforementioned second fixed seat surface. When the aforementioned sling is simultaneously placed inside the aforementioned hook space and inside the connecting groove, the aforementioned sling contacts the aforementioned first turning surface to form a first bend.

5. The cord adjustment device as described in claim 4, wherein, The connecting groove has a second turning surface on the side away from the first turning surface, and the sling contacts the second turning surface to form a second bend that is spaced apart from the first bend.

6. The cord adjustment device as described in claim 1, wherein, The movable body has a movable rod passing through the bearing body and a connecting rod intersecting the movable rod. The opening and closing body is recessed to form an opening and closing track into which the connecting rod can pass, and is pivotally connected to the bearing body, so that the opening and closing body can rotate relative to the bearing body about a rotation axis. The opposite sides of the opening and closing track are respectively provided as a track proximal end close to the rotation axis and a track distal end away from the rotation axis. A track wall surface that can contact the connecting rod is formed from the track proximal end toward the track distal end. When the opening and closing body rotates relative to the bearing body, the connecting rod can selectively move along the track wall to the track proximal end or the track distal end, thereby the connecting rod can move closer to or further away from the rotation axis, allowing the movable rod to move relative to the bearing body.

7. The cord adjustment device as described in claim 6, wherein, The aforementioned opening and closing body has an opening and closing pivot hole communicating with the aforementioned opening and closing track. The opening and closing pivot hole is adjacent to the near end of the aforementioned track. The aforementioned supporting body has a pivot rod that can be inserted into the aforementioned opening and closing pivot hole and a pivot rod groove formed by the recess of the aforementioned pivot rod. When the aforementioned linkage rod moves toward the near end of the aforementioned track through the rotating opening and closing body, the aforementioned linkage rod will enter the interior of the aforementioned pivot rod groove. When the aforementioned linkage rod moves toward the far end of the aforementioned track through the rotating opening and closing body, the aforementioned linkage rod will leave the interior of the aforementioned pivot rod groove.

8. The cord adjustment device as described in claim 6, wherein, The aforementioned opening and closing track is further provided with a track recess between the near end and the far end of the track. The track recess is used to accommodate a portion of the aforementioned linkage rod, so that the linkage rod can temporarily stop moving inside the aforementioned opening and closing track, and the aforementioned opening and closing body can drive the aforementioned movable body to move in multiple stages.

9. The cord adjustment device as described in claim 6, wherein, The aforementioned adjustment mechanism further includes a return spring, which is disposed between the bearing body and the movable body and can deform, so that the return spring can generate a return force acting on the movable body, so that the linkage rod can continuously contact the track wall through the return force.

10. The cord adjustment device as described in claim 6, wherein, The aforementioned adjustment mechanism further includes an adjustment body that can pass through the aforementioned linkage rod and be helically engaged with the aforementioned sling connection body, such that when the adjustment body rotates relative to the aforementioned movable body, the aforementioned sling connection body can selectively move closer to or further away from the aforementioned movable body.

11. The cord adjustment device as described in claim 6, wherein, The aforementioned linkage has a linkage member connected to the aforementioned movable rod and a wheel made of non-metallic material. The wheel is mounted on the end of the aforementioned linkage member and can contact the aforementioned track wall to reduce the friction between the aforementioned linkage and the opening / closing track.
