Abstract
The utility model discloses a three-type traveling combined drum, which comprises a combined drum group and a middle ring plate made of carbon fiber, wherein a pressing ring of a big combined drum in the combined drum group is fixedly connected with the middle ring plate through a screw rod, the front end of the middle ring plate is also provided with two grooves for inserting a back frame connecting rod, and the back frame connecting rod is fastened through a bolt after being inserted into the grooves; the middle part of the front end of the middle ring plate is inwards sunken to form a notch, two middle ring rings made of carbon fiber are hung in the notch, the pressing ring of the middle and small coupling drums in the coupling drum set is fixedly connected with the middle ring rings through a screw rod, and the two middle ring rings are fixedly connected through bolts. The three-type traveling combined drum of the utility model replaces the drum lug through the middle ring plate and the middle ring, so that the structure between the drum cavity and the drum head is tighter, and the drum cavity is prevented from being perforated, so that the drum cavity vibrates better; the middle ring plate and the middle ring are made of carbon fiber, so that the weight is reduced compared with a large number of lugs, and the drum is convenient for players to use.
Description
Technical field
The utility model relates to one and to advance musical instrument, and especially a kind of three types are advanced connection drum.
Background technology
In existing connection drum of advancing, drum chamber, drum head, trim ring and drum ear are drawn together in the bulge of each connection, drum head is pressed in drum chamber by trim ring, drum ear is fixed in drum chamber by bolt, and trim ring is connected by screw rod with drum ear again, and then each connection drum is connected with backrest bolt by drum chamber or drum ear again.When drum ear is arranged in drum chamber, need, to drum chamber perforate, to affect the vibration of drum chamber; And a large amount of uses of drum ear, add the overall weight of connection drum of advancing, increase the burden of player; In addition, in existing connection drum of advancing, each connection drum is all realized by bolt with the connection of backrest, and dismounting is constant.
Summary of the invention
The technical problems to be solved in the utility model be to provide a kind of structure strong and quality is light three types are advanced connection drum.
In order to solve the problems of the technologies described above, the utility model comprises connection drum group and girth sheets in being made up of carbon fibre, described middle girth sheets have multiple for joining the through hole that in bulging group, large connection drum is seated at wherein, drum chamber, drum head and trim ring are drawn together in described large bulge, drum head is pressed in drum chamber by trim ring, trim ring is affixed by multiple screw rod and middle girth sheets, and described centre circle front edge of board is also provided with two grooves inserted for backrest connecting links, is fastened by bolts after described backrest connecting link insertion groove again.
Cave inward in the middle part of described centre circle front edge of board and be formed with recess, be mounted with in described recess two by carbon fibre make in ring, two described middle rings have one for joining the mesopore that the medium and small drum of drum group is seated at wherein, drum chamber, drum head and trim ring are drawn together in described little bulge, drum head is pressed in drum chamber by trim ring, trim ring is affixed with corresponding middle ring by multiple screw rod, is also bolted connection between two described middle rings.
The beneficial effects of the utility model are: three types of the present utility model advance connection drum by middle girth sheets and middle ring alternative drum ear, make the structure between drum chamber and drum head more tight, and drum chamber avoids perforate, drum chamber is vibrated better; Middle girth sheets and middle ring adopt carbon fibre to make, and relative to weight saving a large amount of bulging ears, are convenient to player's use.

Fig. 2 is the plan structure schematic diagram after the utility model removes connection drum group;
Fig. 3 is the main TV structure schematic diagram after the utility model removes connection drum group.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
See Fig. 1 to Fig. 3, three types of the present utility model advance connection bulge draw together connection drum group 1 and by carbon fibre make in girth sheets 2, described middle girth sheets 2 have multiple for joining the through hole 3 that in bulging group 1, large connection drum is seated at wherein, drum chamber, drum head and trim ring are drawn together in described large bulge, drum head is pressed in drum chamber by trim ring, trim ring by multiple screw rod and middle girth sheets 2 affixed, described middle girth sheets 2 front end is also provided with two grooves 4 inserted for backrest connecting link, and described backrest connecting link is fastened by bolts after inserting groove 4 again.
Described middle girth sheets 2 front center caves inward and is formed with recess, be mounted with in described recess two by carbon fibre make in ring 5, what be connected with middle girth sheets 2 in order to middle ring 5 more closely stablizes, can also be reinforced by bolt between, two described middle rings 5 have one for joining the mesopore 6 that bulging group of 1 medium and small drum is seated at wherein, drum chamber is drawn together in described little bulge, drum head and trim ring, drum head is pressed in drum chamber by trim ring, trim ring is affixed with corresponding middle ring 5 by multiple screw rod, also be bolted connection between two described middle rings 5.
Three types of the present utility model advance connection drum by middle girth sheets 2 and the alternative drum ear of middle ring 5, make the structure between drum chamber and drum head more tight, and drum chamber avoids perforate, drum chamber is vibrated better; Middle girth sheets 2 and middle ring 5 adopt carbon fibre to make, and relative to weight saving a large amount of bulging ears, are convenient to player and use.
In sum, content of the present utility model is not limited in the above-described embodiment, and those skilled in the art can propose other embodiment within technological guidance's thought of the present utility model, but these embodiments are all included within scope of the present utility model.
