Embodiment Construction
[0024] Below in conjunction with accompanying drawing and specific embodiment the present invention will be described in further detail:
[0025] see figure 1 with figure 2 , a hammer and pressure ring pressure plate includes a pressure plate body 1 , a pressure spring 2 , a screw rod 3 and a nut 4 .
[0026] Such as figure 2 As shown, the pressing plate body 1 is installed on the pedal hammer bottom plate 5 through the pressing spring 2 . Specifically, the upper end of the stepping hammer bottom plate 5 is affixed with a clip spring mounting post 6, the clip spring mounting post 6 is vertically arranged and fixed with the stepping hammer bottom plate 5 by screws, and the clip spring mounting post 6 can be a threaded post so that it can be connected with the clip spring. 2. The connection is more reliable; the lower part of the pressure plate body 1 forms a compression spring connection column 11, and an annular groove is reserved when the lower part of the pressure plate...

The invention discloses a tread hammer pressing ring pressing plate comprising a pressing plate body, a pressing spring, a screw and a nut; the pressing plate body is installed on a tread hammer bottom plate through the pressing spring, the middle of the upper end of the pressing plate body is sunken downwards to form a spherical groove, a groove used for preventing rotation is formed in the spherical groove, and an oblong hole is further formed in the bottom of the spherical groove in a penetrating mode; one end of the screw is fixedly connected to the tread hammer bottom plate, and the otherend of the screw penetrates through the oblong hole and vertically extends upwards; and the nut is in threaded connection with the upper end of the screw, a spherical surface is formed at the bottomof the nut and matched with the spherical groove, and an anti-rotating block is arranged on the spherical surface of the nut and matched with the groove. The tread hammer pressing ring pressing platein the invention is novel in structure, good in stability and convenient to use.
Description
technical field [0001] The invention relates to a stepping hammer, in particular to a stepping hammer pressure ring pressing plate. Background technique [0002] The front end of the pedal hammer is equipped with a locking mechanism, which is used to clamp the pressure ring of the drum, so that the pedal hammer is fixed on the drum. Generally, the pedal locking mechanism mainly includes an upper pressing plate and a backing plate arranged at the front end of the treading hammer bottom plate, wherein the middle part of the upper pressing plate is hinged to the pedal hammer bottom plate through a shaft, and a torsion spring is set on the shaft, and one end of the torsion spring rests on the The lower end surface of the rear end of the upper pressing plate and the other end are against the bottom plate of the pedal hammer, so that the front end of the upper pressing plate is pressed downwards, and the bass drum pressure ring is clamped between the upper pressing plate and the b...
