Description
Technical field
The utility model provides a kind of jazz's big drum draw-tube simple and easy quick locator card fixing apparatus; Especially refer to that it technically is provided with bite on the interior bar of draw-tube; Cooperate with the fixing sheet that is provided with in the outer tube with corresponding bite; And see through the pin packing and should fix sheet, the bar engaging is positioned in the outer tube in making, but reaches the purpose of the instrument of exempting from and rapid traverse.
Background technology
Big drum has simple and honest music, is the key player in the band, and the big drum of general two pedal sees through the user and tramples a wherein pedal; Directly its drumstick of transmission is beaten a drum, and when the user tramples another pedal again, then can beat a drum by kinematic link drive drumstick; The structure of the two pedal connecting rod of general big drum mainly is made up of a universal joint and a draw-tube, and the bar socket is formed in this draw-tube one outer tube and again, when user's desire is adjusted the length of connecting rod; Need this interior bar relative length in this outer tube of adjustment; And the screw of packing screw by this outer tube top be screwed into, make the bottom of packing screw be urged to masthead face in this, reach fixing purpose after the adjustment length.Yet above-mentioned structure has following shortcoming in use:
One, it is big to trample the jarring forces of drumstick pedal, if simple use screw locks and in the process of transmission, produces vibrations easily and get loose, cause uncertain and uncontrollable rhythm of beating a drum of transmission and power, and then quality is played in influence.
Two, screw must see through wrench or other hand tools and assist locking and unclamp when locking, and is quite inconvenient in the process of adjustment or assembling.
Summary of the invention
For improving above-mentioned problem, the purpose of the utility model is to provide a kind of jazz's big drum draw-tube simple and easy quick locator card fixing apparatus, and it is simple in structure, and operation and dismounting are convenient, does not need extra use hand tool rapid traverse to adjust.
For realizing above-mentioned purpose, the utility model discloses the simple and easy quick locator card fixing apparatus of a kind of jazz's big drum draw-tube, it is characterized in that including:
One outer tube, the internal diameter of this outer tube are sexangle and the below has a storage tank;
Bar in one, bar is the hexagon prism of this outer tube diameter of cooperation and is placed in this outer tube in this, bar is provided with one first bite towards the outside surface of this storage tank in being somebody's turn to do again; And
One clamping device; This clamping device includes one and fixes a sheet and a pin; This fixing sheet is located in this storage tank; And this fixing sheet is provided with one second bite that cooperates with this first bite, and this pin is inserted in this outer tube by a perforation of this outer tube side, thereby and a packing this fixings sheet of being provided with of this pin so that this second bite fixes the packing face that reaches fixing this outer tube and be somebody's turn to do interior bar purpose with this first bite interlock.
Wherein, this first bite and this second bite are the tooth-shape structure that cooperatively interacts.
Wherein, this first bite and this second bite are the texture structure that cooperatively interacts.
Wherein, this first bite and this second bite are the arcuate structure that cooperatively interacts.
Wherein, the both side edges of this fixing sheet has the lead hypotenuse of this fixing sheet below of this pin entering of a guiding with this fixing sheet of packing respectively.
Wherein, this pin more comprises one and forms the slack side of step structure with this packing face.
Through said structure, the simple and easy quick locator card fixing apparatus of jazz's big drum draw-tube of the utility model is provided with bite in interior bar, and in outer tube, the fixing sheet with corresponding bite is set; But the packing face packing that sees through the pin insertion fixes sheet is close to interior bar, the bite of bar and the mutual interlock fixing of the bite that fixes sheet, bar and outer tube in can fixing really in making; Also be not easy in the use to get loose; Moreover, when adjusting the length of interior bar and outer tube, only need pin be retreated to slack side as if needs; After the bite that fixes sheet is not fitted with interior bar bite; Bar and adjust distance in can fast moving, reaching does not need the extra use hand tool can the rapid traverse adjustment, solves and uses problems such as hand tool inconvenience and screw are prone to get loose in use in the past.

Embodiment
Consult Fig. 1 to shown in Figure 7, the utility model provides a kind of jazz's big drum draw-tube simple and easy quick locator card fixing apparatus, mainly is the draw-tube that is installed between big drum as shown in Figure 1 two pedals, includes:
One outer tube 1, the internal diameter of this outer tube 1 are the storage tank 10 that sexangle and below have rectangle;
One clamping device 3, this clamping device 3 include one and fix a sheet 31 and a pin 33, and this fixing sheet 31 is located in this storage tank 10; And this fixing sheet 31 is provided with one second bite 311 that cooperates with this first bite 21, and the both side edges of this fixing sheet 31 has the hypotenuse of leading 313 respectively again, wherein; This pin 33 is a stairstepping; Include a slack side 331 and a packing face 332, this pin 33 is inserted by the perforation 11 of this outer tube 1 side again, and then gets in this outer tube 1; And lead hypotenuse 313 along this of this fixing sheet 31 and insert this fixing sheet 31 belows; And should fix sheet 31 with this packing face 332 packings on this pin 33, and then this second bite 311 and this first bite, 21 interlocks are fixed, reach fixing this outer tube 1 with should in the purpose person of bar 2.Wherein, this first bite 21 can be tooth-shape structure, texture structure or the arcuate structure person who cooperatively interacts with this second bite 311.
By this; When the user need adjust the length of draw-tube; Only need this pin 33 is smoked (like Fig. 4 and shown in Figure 5); Make this slack side 331 of this pin 33 be resisted against this fixing sheet 31 belows, this moment, this second bite 311 of this fixing sheet 31 did not fit with this first bite 21, and should be able in this outer tube 1, move by interior bar 2 this moment; When the user should in bar 2 when in this outer tube 1, being adjusted to suitable length; Only need this pin 33 is pressed into (like Fig. 6 and shown in Figure 7); Make this fixing sheet 31 of this packing face 332 packings of this pin 33, make this fixing sheet 31 be close to bar 2 in this, and then this second bite 311 and these first bite, 21 mutual interlocks are fixed; These interior bar 2 certain engagings are positioned in this outer tube 1, but reach the purpose of the instrument of exempting from and rapid traverse.
