Problems solved by technology
[0004] like figure 1 As shown, the extension spring device in the existing pedal hammer generally includes extension spring block I1a, extension spring I2a and extension spring tension adjustment mechanism I3a; extension spring block I1a is directly fixedly connected with the adjustment square shaft through bolts; extension spring tension adjustment mechanism I3a Including screw rod 31a and two locking nuts 32a, the outer lower part of the column is made into a fixed plate 4a with a screw hole, the screw rod 31a is vertically threaded in the screw hole of the fixing plate 4a, and the two locking nuts 32a are installed on On the screw rod 31a, and two lock nuts 32a are placed on the upper and lower ends of the fixed plate 4a to lock the screw rod 31a on the fixed plate 4a; the extension spring I2a is hooked between the extension spring block I 1a and the screw rod 31a ; When the tension of extension spring I2a needs to be adjusted, loosen the two locking nuts 32a, then turn the screw rod 31a to adjust the position, and after the adjustment is in place, the screw rod 31a is locked on the fixed plate 4a by the two locking nuts 32a, wherein During the rotation of the screw 31a, since the tension of the tension spring I2a is very large, it takes a lot of force to complete the adjustment, and the position of the tension spring tension adjustment mechanism I3a is close to the ground, and the operating space is small, which is not conducive to adjustment. And it is inconvenient to use, which will give users a poor experience and reduce the market competitiveness of the product

The invention discloses a treading hammer tension spring device which comprises a tension spring block, a tension spring and a tension spring tension adjusting mechanism, and the tension spring is connected between the tension spring block and the tension spring tension adjusting mechanism. The tension spring tension adjusting mechanism comprises a shell, a mounting plate, a rotating shaft, a wormwheel, a worm and a steel wire rope; the shell is rotationally connected with the stand column. The mounting plate is fixedly connected inside the shell; the rotating shaft is rotatably and transversely mounted on the mounting plate; the worm wheel is coaxially and fixedly connected to the end part of the rotating shaft; the worm is rotatably mounted on the mounting plate, one end of the worm ismatched with the worm wheel for use, and the other end of the worm penetrates through the shell and extends outwards; the other end of the steel wire rope penetrates through the shell and is connectedwith the tension spring; the worm is rotated to drive the worm wheel and the rotating shaft to rotate so as to drive the steel wire rope to wind around the rotating shaft, and tension adjustment of the tension spring is achieved. The device is suitable for various types of treading hammers, and has the characteristics of reasonable structure, simplicity and convenience in installation, convenience in operation and the like.
Description
technical field [0001] The invention relates to a stepping hammer, in particular to a stepping hammer extension spring device. Background technique [0002] The drum kit is a jazz drum, which is a very important percussion instrument in a jazz band. A hi-hat with a pedal and other parts. [0003] Wherein the playing of big drum usually needs to be provided with stepping hammer to hit the drum surface to perform, and stepping hammer generally mainly comprises base plate, column, pedal, chain, adjusts square shaft, connecting block, tup and extension spring device. Specifically, there are two columns and they are symmetrically fixed on the front end of the bottom plate; the tail end of the pedal is hinged on the bottom plate, and the front end is connected to the connecting block through a chain; the connecting block is fixed on the adjusting square shaft; the adjusting square shaft is rotatably installed on the Between two uprights; the hammer head is fixedly connected to t...
