Problems solved by technology

[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

Embodiment Construction

[0012] Below in conjunction with accompanying drawing and specific embodiment the present invention will be described in further detail:

[0013] see Figure 1 to Figure 3 The sand belt adjustment mechanism of the present invention includes two structurally consistent adjustment members that are symmetrically arranged on the drum cavity and respectively connected to the two ends of the sand belt. The two-way adjustment of the sand belt can be realized by adopting two adjusting parts arranged at both ends of the sand belt.

[0014] The adjusting member includes a fixing base 1, a sliding cover 2 and an adjusting bolt 3, the fixing base 1 is fixedly installed on the drum cavity, specifically, the fixing base 1 is fixedly connected with the drum cavity by two bolts. The fixing base 1 is also provided with a connecting block 4 , and a threaded hole matching the adjusting bolt 3 is formed through the connecting block 4 .

[0015] The sliding cover 2 can be slidably installed on t...

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...
