Sand belt adjusting mechanism

Abstract

The invention discloses a sand belt adjusting mechanism, which comprises two adjusting pieces connected separately with both ends of the sand belt. The adjusting piece comprises a fixing seat, a sliding cover and an adjusting bolt. The fixing seat is fixedly arranged on a drum cavity, and a connecting block is arranged on the fixing seat. A threaded hole is formed in the connecting block in a passing mode. The sliding cover is vertically slideably arranged on the fixing seat, and the end surface of the sliding cover is provided with a mounting plate connected with the end part of the sand belt. The upper part of the adjusting bolt is rotarily arranged on the sliding cover, a threaded rod at the lower part of the adjusting bolt is mounted on the connecting block, and through rotating the adjusting bolt, the sliding cover can be driven to move vertically relative to the fixing seat to realize elastic adjustment on the sand belt. The two adjusting pieces are arranged at two ends of the sand belt, two-direction adjustment on the sand belt can be realized, and in particular, through rotating the adjusting bolt, the sliding cover can be driven to move vertically relative to the fixing seat to realize elastic adjustment on the sand belt, the adjustment mode is linear, and calibration adjustment of the sand belt after deformation is facilitated.

Description

technical field [0001] The invention relates to a musical instrument accessory, in particular to a sand belt adjustment mechanism. Background technique [0002] In the existing sand belt drum, one end of the sand belt is fixedly connected to the drum cavity, and the other end uses a quick-fit wrench to realize the tightness adjustment of the sand belt, and then adjust the distance between the sand belt and the drum surface to achieve different timbres. The design can only make one loose and one tight adjustment to the sand belt, and cannot realize linear adjustment. After a long time of use, the sand belt will have a certain deformation. The existing adjustment mechanism is difficult to achieve calibration and adjustment of the sand belt, which reduces the Product quality affects the user experience. Contents of the invention [0003] The purpose of the present invention is to solve the above technical problems and provide a sand belt adjustment mechanism capable of reali...
