Technical Field
[0001] This utility model relates to the field of hi-hat stand technology, specifically to a hi-hat stand pedal fixing device. Background Technology
[0002] The drum kit is a very important pitchless percussion instrument in a jazz band. It is usually composed of a bass drum, hi-hat, snare drum, tom-toms, and cymbals. The cymbals include hi-hat, ricochet, spiking cymbals, mud cymbals, Chinese cymbals, and alto cymbals. The hi-hat is fixed to the hi-hat stand. The upper part of the foot pedal is connected to the connecting rod inside the cymbal stand. The connecting rod is fitted with a cymbal core spring. When the player presses the pedal, the pedal will move the connecting rod up and down. The cymbal core spring will move and extend along with the movement of the connecting rod, thereby causing the two cymbals to strike each other and produce sound.
[0003] However, the connection between the pedal and the lever in the existing technology mostly adopts a direct chain drive structure, but it still has the following defects: the chain is prone to non-perpendicular friction due to angular deviation during the pulling process, which causes drive jamming, accelerated wear of parts, and the chain is prone to deformation or breakage after long-term use. In addition, the existing device lacks effective adjustment function, and users cannot flexibly adjust the pedal height according to the performance needs, resulting in a limited performance experience. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing a cymbal stand pedal fixing device, so as to achieve flexible adjustment of the pedal height while reducing pedal jamming.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] This utility model provides a pedal fixing device for a hi-hat stand, comprising: a gantry frame body, a cam component, a sawtooth adjustment assembly, and a pedal assembly;
[0007] The gantry frame body has a receiving space for accommodating the cam component. The cam component is rotatably disposed inside the receiving space. One end of the sawtooth adjustment assembly is rotatably connected to the cam component, and the other end is connected to the pedal assembly. The pedal assembly is disposed on the gantry frame body and can be stepped on and rotated relative to the gantry frame body. When the pedal assembly is stepped on and rotates relative to the gantry frame body, the pedal assembly drives the cam component to rotate through the sawtooth adjustment assembly, and the sawtooth adjustment assembly moves in the vertical direction.
[0008] In some embodiments, the cam component includes a cam body and a guide portion. One end of the guide portion is fixed to the cam body, and the other end is rotatably connected to the sawtooth adjustment assembly. When the sawtooth adjustment assembly is disposed on the guide portion, the sawtooth adjustment assembly is tangent to the arc of the cam body.
[0009] In some embodiments, the sawtooth adjustment assembly includes a first sawtooth component, a second sawtooth component, a connecting shaft, and a connecting rod. The first sawtooth component has a first sawtooth on the side facing the second sawtooth component, and the second sawtooth component has a second sawtooth on the side facing the first sawtooth component. The first sawtooth and the second sawtooth mesh. The bottom of the first sawtooth is rotatably connected to the connecting rod through the connecting shaft, and the connecting rod is rotatably connected to the pedal assembly.
[0010] In some embodiments, the saw tooth adjustment assembly further includes a locking bolt. The first saw tooth has a through-hole, and the second saw tooth has a through-hole that mates with the locking hole. The locking hole extends along the length of the first saw tooth, and the threaded hole extends along the length of the second saw tooth. The locking bolt passes through the locking hole and the threaded hole in sequence to lock the first saw tooth and the second saw tooth.
[0011] In some embodiments, the gantry frame body has a bearing hole, and the cam body is rotatably disposed inside the bearing hole via a bearing.
[0012] In some embodiments, the pedal assembly includes a large pedal, a small pedal, and a pedal bracket. The pedal bracket is disposed on the gantry frame body, the small pedal is fixed at one end between the pedals, one end of the large pedal is rotatably connected to the small pedal, and the other end is rotatably connected to the connecting rod.
[0013] In some embodiments, the system further includes a support leg and a fastener, wherein the support leg is disposed on the top of the gantry frame body and the fastener is sleeved on the support leg to lock the support leg to the gantry frame body.
[0014] Furthermore, the beneficial effects of this utility model are as follows:
[0015] This utility model adopts a scheme in which the cam body and the gantry body are rotated. This ensures that when the pedal assembly is stepped on, the guide part of the cam and the sawtooth adjustment assembly form a tangential contact, thus ensuring a precise power transmission path. This further ensures that the sawtooth adjustment assembly moves in a straight line in the vertical direction, thereby ensuring that the pull rod always moves in the vertical direction. This completely eliminates the frictional resistance caused by chain skewing, improves drive smoothness, and extends the service life of the components.
[0016] In addition, this utility model is provided with a sawtooth adjustment component with a sawtooth structure, and the sawtooth adjustment component includes a first sawtooth component and a second sawtooth component that mesh with each other. When it is necessary to change the height of the large pedal, the manual adjustment only needs to adjust the meshing sawtooth between the first sawtooth component and the second sawtooth component. At the same time, the gantry body and the pedal component adopt a split design, which is convenient for assembly and maintenance and adapts to the mechanical requirements of different performance scenarios.

[0022] like Figures 1-3 As shown, this utility model embodiment provides a cymbal frame pedal fixing device, including: a gantry frame body 2, a cam component, a sawtooth adjustment assembly, and a pedal assembly;
[0023] The gantry frame body 2 has a receiving space 22 for accommodating the cam component. The cam component is rotatably disposed inside the receiving space 22. One end of the sawtooth adjustment assembly is rotatably connected to the cam component, and the other end is connected to the pedal assembly. The pedal assembly is disposed on the gantry frame body 2 and can be stepped on and rotated relative to the gantry frame body 2. When the pedal assembly is stepped on and rotates relative to the gantry frame body 2, the pedal assembly drives the cam component to rotate through the sawtooth adjustment assembly, and the sawtooth adjustment assembly moves in the vertical direction. The cam component includes a cam body 4 and a guide portion 41. One end of the guide portion 41 is fixed to the cam body. 4. The other end is rotatably connected to the sawtooth adjustment assembly. When the sawtooth adjustment assembly is set on the guide part 41, the sawtooth adjustment assembly is tangent to the arc of the cam body 4. The sawtooth adjustment assembly includes a first sawtooth part 3, a second sawtooth part 31, a connecting shaft 33, and a connecting rod 34. The first sawtooth part 3 is provided with a first sawtooth on the side facing the second sawtooth part 31, and the second sawtooth part 31 is provided with a second sawtooth on the side facing the first sawtooth part 3. The first sawtooth and the second sawtooth mesh. The bottom of the first sawtooth is rotatably connected to the connecting rod 34 through the connecting shaft 33. The connecting rod 34 is rotatably connected to the pedal assembly.
[0024] The gantry frame body 2 serves as the main support structure, with a bearing hole 21 at its top and an internal bearing 42 for mounting the cam body 4. The cam component consists of the cam body 4 and a guide part 41. The end of the guide part 41 is rotatably connected to the sawtooth adjustment assembly, and the linearity of power transmission is ensured through an arc tangent design. The sawtooth adjustment assembly includes a first sawtooth component 3, a second sawtooth component 31, and a connecting shaft 33. The two sawtooth components achieve height adjustment through meshing teeth. A locking bolt 32 passes through a locking hole and a threaded hole, and the adjusted position is fixed by tightening. The pedal assembly consists of a large pedal 1, a small pedal 11, and a bracket. When stepped on, the small pedal 11 drives the large pedal 1 to rotate, which in turn drives the sawtooth adjustment assembly to move vertically via the connecting rod 34, ultimately causing the cam to rotate. The sawtooth adjustment assembly also includes a locking bolt 32. The first sawtooth member 3 has a through-hole locking hole, and the second sawtooth member 31 has a through-hole threaded hole that mates with the locking hole. The locking hole extends along the length of the first sawtooth member 3, and the threaded hole extends along the length of the second sawtooth member 31. The locking bolt 32 passes through the locking hole and the threaded hole in sequence to lock the first sawtooth member 3 and the second sawtooth member 31. In this embodiment, the device in this invention needs to be used in conjunction with the connecting rod inside the cymbal bracket. For example, the connecting rod and... The sawtooth assembly in this application is connected, and the connecting rod is on the same straight line as the first sawtooth piece 3 or the second sawtooth piece 31 in the sawtooth assembly. This application does not make specific limitations on this. When the performer steps on the pedal assembly, the pedal assembly will drive the connecting rod to move up and down. The cymbal core spring will move and extend along with the movement of the connecting rod, thereby driving the two cymbals to strike each other and produce sound. The specific operation is as follows: when the performer steps on the pedal, the force is transmitted to the sawtooth assembly through the connecting rod 34, driving the cam body 4 to rotate around the bearing 42. The arc surface of the cam body 4 cooperates with the guide part 41 to ensure the linear movement of the connecting rod. When the height needs to be adjusted, the locking bolt 32 is loosened, the meshing position of the first sawtooth piece 3 and the second sawtooth piece 31 is slid to the required scale, and then locked, so as to accurately fix the pedal height.
[0025] In one possible implementation, the gantry frame body 2 has a bearing hole 21, and the cam body 4 is rotatably disposed inside the bearing hole 21 via a bearing 42. In the above structure, the bearing 42 can effectively reduce the rotational friction of the cam body 4, extend the life of the device, and reduce the maintenance frequency.
[0026] In one possible implementation, the pedal assembly includes a large pedal 1, a small pedal 11, and a pedal bracket 12. The pedal bracket 12 is disposed on the gantry body 2, and the small pedal 11 is fixed at one end between the pedals. One end of the large pedal 1 is rotatably connected to the small pedal 11, and the other end is rotatably connected to the connecting rod 34. In the above structure, this application also provides a fixed small pedal 11 at the tail end of the large pedal 1, wherein the small pedal 11 is fixedly connected to the pedal bracket 12, so that when the performer steps on the large pedal 1, the heel position is supported by the small pedal 11, thereby further improving the operating comfort and response speed.
[0027] One possible implementation also includes a support leg 5 and a fixing member 6. The support leg 5 is located on top of the gantry body 2, and the fixing member 6 is sleeved on the support leg 5 to lock the support leg 5 to the gantry body 2. The support leg 5 and the fixing member 6 reinforce the gantry through a sleeve structure to prevent the support from shaking during performance. This implementation achieves high-precision, low-friction power transmission through mechanical linkage and modular design, meeting diverse performance needs.
[0028] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
