Abstract

The utility model relates to a bass drum jacking support universal regulator and belongs to the music instrument field. The utility model is characterized in that two pressure plates (a right one and a left one) are arranged in a reaming base. Radial semicircle through holes with same diameter of which the lower inner rim provided with inner rim teeth mesh with outer rim teeth on the top of connection shaft fixed with steel pipe are arranged on the relative coincident surface of the two platens along the radial direction respectively, radial teeth which mesh with the radial teeth on inner surface of the left platen are arranged on the other surface of the left platen near the outer rim. The left platen, the right platen and a gland bush are all fastened by a tightening bolt meshing with the locked knob on the meshing gland bush and the axis. The utility model has the advantages of simple and reasonable structure, three dimensional and fast adjustment and reliable quick location, thereby overcoming existing problems such as repeated and single adjustment of the prior drum jacking support regulator and ensuring music tune of drum in the whole band.

Description

Big drum ceiling hold universal adjustment device

Technical field

The utility model belongs to the musical instrument field, the employed big drum ceiling hold of especially a kind of frame drum universal adjustment device.

Background technology

Frame drum in the musical instrument is a kind of percussion instrument, beat the big drum hit and several eardrums of installing by support constitutes by stepping on this big drum, several eardrums of being installed all are fixed together with big drum, as required, at any time eardrum are carried out three-dimensional and regulate.The structure of currently used support is such: steel pipe is located respectively by clip and is packed on big drum and the eardrum, the free bearing of adjusting two upper and lower pendulum angles of steel pipe by locking knob is installed between these two steel pipes, and the angle that the left and right adjusting of eardrum is then needed to unclamp clip, rotate steel pipe can realize.The shortcoming of this structure is: 1. the regulatory function of eardrum is more single, and adjusting especially diametrically is very inconvenient, can not realize the adjusting of eardrum on three-dimensional simultaneously; 2. the free bearing location of adopting is unreliable, the easy bottom displacement of eardrum under drummer's knocking, and the integral body that influences eardrum and band is played happy the accent.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple in structure, and eardrum can carry out three-dimensional regulation at any time easily and locate reliable big drum ceiling hold universal adjustment device.

The utility model is achieved through the following technical solutions:

This big drum ceiling hold universal adjustment device, by steel pipe, clip, free bearing, locking knob constitutes, clip is installed on the steel pipe, it is characterized in that: a left side is installed in the free bearing, right two platens, the footpath of the relative coincidence face of these two platens upwards is shaped on the isometrical half-round cross hole of latus rectum respectively, the lower internal edge of these two isometrical half-round cross holes all be shaped on can with the made outer rim teeth in the coupling shaft upper end that steel pipe the is solidly installed inner edge teeth of interlock mutually, the card outer rim place of the another side of left side platen is shaped on radially teeth with the footpath, this radially teeth can with made radially teeth interlock mutually on the card in the gland, a left side, right platen, a fastening bolt of locking knob is realized fastening on the engageable gland that gland all covers by the axle center.

And, on the fastening bolt between gland and the left platen, a stage clip is installed.

Advantage of the present utility model and beneficial effect are:

1. adopt be connected outer rim teeth and of the formed inner edge teeth of the coincidence face through hole of left and right platen by locking knob unclamps or the mode of locking realizes free bearing and coupling shaft radially rotation or location, can ideally solve the problem of eardrum radiai adjustment inconvenience in the prior art, and one-piece construction is simple and practical, adjust efficient and conveniently, overcome the deficiencies in the prior art part fully.

2. adopt on another card of left platen with the interlock and by locking knob unclamps or the mode of locking can realize free bearing and coupling shaft axial wobble and location mutually of the radially teeth of the made radially teeth in footpath and gland, and teeth interlock mode locatees comparatively reliably, overcome the difficult problem of eardrum in the down easy bottom displacement of fiercely knocking of drummer.

3. the utility model one-piece construction advantages of simple, but three-dimensional regulation and regulate smooth and easy rapidly fast, accurate positioning is reliable and stable, has overcome existing bulging ceiling hold and has regulated single and problem such as adjustings repeatedly, and the integral body that has guaranteed eardrum and band is effectively played and is found pleasure in accent.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is further described, but is not limited to the concrete structure that present embodiment is narrated.

This big drum ceiling hold universal adjustment device, the syndeton of itself and big drum and eardrum (eardrum and big drum are all not shown in the present embodiment) is: the bottom of the steel pipe 1 that installs by clip 2 location with eardrum is packed on the free bearing 3, install a coupling shaft 6 with big drum by the steel pipe 7 that clip 8 location install, this coupling shaft and free bearing are installed.The structure of free bearing is such: be coaxially installed with left platen 9 and right platen 10 in the free bearing, the footpath of the relative coincidence face of these two platens upwards is shaped on the isometrical half-round cross hole of latus rectum respectively, lower internal edge at these two isometrical half-round cross holes all is shaped on the inner edge teeth, these inner edge teeth after the opposite face of left and right platen overlaps, can form an inner edge teeth circular hole and with made outer rim teeth cylinder 14 interlocks mutually in coupling shaft upper end; The card outer rim place of the another side of left side platen is shaped on radially teeth 11 with the footpath, this radially teeth can with made radially teeth interlock mutually on the cards in the gland 5, the locking knob 4 on a fastening bolt 13 engagement glands that left platen, right platen and gland all cover by the axle center is realized unclamping with fastening of above-mentioned several parts.One stage clip 12 is installed on the fastening bolt between gland and the left platen.

Principle of work of the present utility model is:

The axial wobble of the relative big drum of eardrum and location are that the mutual interlock by the made radially teeth of radially teeth made on the gland and left platen realizes.When locking knob unscrewed, radially teeth were thrown off mutual interlocking pattern under the effect of stage clip, realized the axial wobble of the relative eardrum of big drum; When locking knob screwed, radially the mutual interlock of teeth realized the location.

The axial rotation of the relative big drum of eardrum and location are the interlock realizations of outer rim teeth cylinder and the inner edge teeth circular hole that can form after the opposite face of left and right platen overlaps by coupling shaft upper end.When locking knob unscrewed, the gap increased between the left and right platen, made the inner edge teeth throw off the interlock of the outer rim teeth of coupling shaft, realized the relatively rotating of coupling shaft and free bearing (even also axial rotation of eardrum and big drum); When locking knob screwed, the faying face between the left and right platen was adjacent to, and progressively the be connected outer rim teeth of axle of inner edge teeth are fixed until interlock, realized the axial positioning of rotating of eardrum and big drum.
