Abstract
The invention discloses a pull-rod nut of a marching military drum, wherein the upper end of the pull-rod nut is provided with an upper bolt, the lower end thereof is connected with a pull rod, the pull-rod nut comprises a hexahedron and a tube body both which are integrally formed, screw threads are formed on the outer wall of the tube body and in the inner hole thereof, the tube screw threads on the upper end of the hexahedron are connected with a middle ring, upper bolts and screws pass through the screw threads on the upper pressing ring and connect into the inner hole on the upper end of the tube body, the screw threads on the upper end of the pull rod are connected with the outer wall of the tube body on the lower end of the hexahedron, and the lower end thereof is connected with the lower bolt which passes through the screw threads of the lower pressing ring and connects to the lower end of the pull rod. The pull-rod nut is installed on the lower end of the middle ring, connected with the upper bolt and the pull rod through the tube body, the pull rod is connected with the lower bolt so that the upper and lower pressing rings, and the middle ring are together tensioned and the upper and lower drum heads are further pressed, the installing difficulty is reduced, besides vibration influence among all parts is reduced by installing an elastic spacer and an annular elastic ring so that the connection structure of the middle ring, and the upper and lower pressing rings is more steady.
Description
Technical field
The present invention relates to a kind of nut, especially a kind of advance military drum pull-rod nut.
Background technique
The drum barrel outer wall of advance military drum is often provided with middle base, between middle base and the upper and lower trim ring of advance military drum, drum head is pressed on drum barrel by pull bar is arranged on and ensure that the stability of whole advance military drum.But middle base is arranged on drum barrel, drum barrel needs punching, destroy drum chamber, have impact on the performance tonequality of advance military drum.In order to avoid installing middle base on drum barrel, now a kind of longer pull bar of normal employing replaces middle base, concrete structure is: the two ends of pull bar are connected to a bolt, a bolt is connected with pull bar threaded upper ends with centre circle through upper trim ring, and another bolt is threaded with pull bar lower end through lower clamping ring.Such structure effectively prevent destruction drum chamber, by pull bar being fixed together upper and lower trim ring tightness adjustable, but such structure when mounted, and needing upper and lower trim ring to install together could tighten up upper and lower drum head simultaneously, inconvenience is installed, increases the work difficulty of assembly crewman; And upper and lower trim ring by means of only pull bar with simple cooperation of bolt realize straining, poor stability, especially use advance military drum play time, the impact that the joint of pull bar and bolt is shaken easily loosens, and affects the playing effect of advance military drum.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of simple installation and the strong advance military drum pull-rod nut of stability.
In order to solve the problems of the technologies described above, upper end of the present invention is connected with bolt, lower end is connected with pull bar, described advance military drum pull-rod nut comprises hexahedron and runs through the body be arranged in the middle part of described hexahedron, described hexahedron and described body are made into integration, all screw thread is formed with on described tube wall and in endoporus, the body being arranged in described hexahedron upper end is threaded in the tapped hole of advance military drum centre circle, described upper bolt screw rod is threaded in the endoporus of described body upper end through the upper trim ring of advance military drum, described pull bar threaded upper ends be connected to be positioned at described hexahedron lower end body outer wall on, lower end is connected with bolt, this lower bolt screw rod is threaded in described pull bar lower end through the lower clamping ring of advance military drum.
On described tube wall and the position being close to described hexahedron upper-end surface is formed with an annular slot, outside this annular slot, be set with a resilient pad.
Be formed with an annular groove in the middle part of described hexahedron lower end surface, this annular groove inner circumferential wall is coated with one deck annular resilient collar, on the outer wall of described pull bar upper end, depression is formed with an annular breach mated with described annular groove.
Described resilient pad and described annular resilient collar are made by rubber material.
The present invention is arranged on the centre circle lower end of advance military drum, upper bolt is connected by body inner hole thread, make together with trim ring strains with centre circle, and then compress upper drum head, to be threaded pull bar by body lower end, pull rod screw connects lower bolt, make together with lower clamping ring strains with centre circle, and then compress lower drum head, reduce installation difficulty, and by adding resilient pad between hexahedron and centre circle, between hexahedron and pull bar, add annular resilient collar decrease the impact shaken between each parts, make centre circle and upper, linkage structure between lower clamping ring is more stable.
Accompanying drawing explanation
Fig. 1 is the structural representation that advance military drum pull-rod nut of the present invention is arranged on advance military drum;
Fig. 2 is the structural representation of advance military drum pull-rod nut of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
See Fig. 1 and Fig. 2, advance military drum pull-rod nut upper end of the present invention is connected with bolt 1, lower end is connected with pull bar 2, described advance military drum pull-rod nut comprises hexahedron 3 and runs through the body 4 be arranged in the middle part of described hexahedron 3, described hexahedron 3 is made into integration with described body 4, on described body 4 outer wall and be all formed with screw thread in endoporus, the body 4 being arranged in described hexahedron 3 upper end is threaded in the tapped hole of advance military drum centre circle 5, described upper bolt 1 screw rod is threaded in the endoporus of described body 4 upper end through the upper trim ring 6 of advance military drum, described pull bar 2 threaded upper ends be connected to be positioned at described hexahedron 3 lower end body 4 outer wall on, lower end is connected with bolt 7, this lower bolt 7 screw rod is threaded in described pull bar 2 lower end through the lower clamping ring 8 of advance military drum.Connect upper bolt 1 by body 4 inner hole thread, make together with trim ring 6 strains with centre circle 5, and then compress and go up drum head, to be threaded pull bar 2 by body 4 lower end, pull bar 2 is threaded lower bolt 7, makes together with lower clamping ring 8 strains with centre circle 5, and then compress lower drum head, reduce installation difficulty.
