Stability, and the junction of pull rod 10 and the first turntable 9 and the first strut 6 is socketed with damped ring, more improves pull rod 10
Stability in lock state.
The present invention also provides the intersection shaft type brackets and its application method of a kind of musical instrument support, when operating when in use
The following steps are included:
Step 1: pull rod locking of the mechanism that unlocks 14 to the first turntable 9 and the second turntable 13: is pulled out manually
10, so that pull rod 10 is mobile to the outside of lantern ring 5, pulling force, top are applied to mandril 16 by connecting rod 15 while shifting outside pull rod 10
It is moved along guide sleeve 19 to the center of lantern ring 5 after 16 under tension of bar, mobile 17 synchronizing moving of drive fixture block of mandril 16, this mistake
Medial surface of the fixture block 17 far from neck bush 20 in journey, and to close at the central axis of neck bush 20, until fixture block 17 and guiding
19 deduction of set, stops drag pull rod 10, fixture block 17 is not contacted with neck bush 20 at this time, and the first turntable 9 and the second turntable 13 can
It relatively rotates；
Step 2: the bearing height of adjusting bracket: locking mechanism 14 unlocks to the first turntable 9 and the second turntable 13
Afterwards, apply upward power to support plate 2 with hand, lean on two the first sliding blocks 11 mutually along the first guide rail 3
Closely, two the second sliding blocks 12 are close to each other along the second guide rail 4, i.e. angle a becomes smaller in Fig. 1, and angle a becomes smaller so that the first strut 6 and
Two struts 7 are intended to vertical shape, i.e. support plate 2 increases, and after support plate 2 rises to required height, protect support plate 2 not
It is dynamic, and to pressing pull rod 10 on the inside of lantern ring 5, so that medial movement of the pull rod 10 to lantern ring 5, pass through company while shifting in pull rod 10
Bar 15 applies thrust to mandril 16, mandril 16 by after thrust along guide sleeve 19 to moving at the inner wall of lantern ring 5, the shifting of mandril 16
It is dynamic to drive 17 synchronizing moving of fixture block, during this fixture block 17 close to neck bush 20 medial surface, until teeth on fixture block 17 with
Teeth are intermeshed on neck bush 20, pull rod 10 are stopped drag, at this time since the direction of rotation of two neck bush 20 is on the contrary, therefore
Fixture block 17 plays locking effect to two neck bush 20, i.e., complete so that the first turntable 9 and the second turntable 13 can not relatively rotate
The adjusting of the height of pairs of support plate 2；
When needing the height by support plate 2 to turn down, pull rod 10 is pulled out to outside lantern ring 5, is released to the first turntable 9 and second
The locking of turntable 10, and support plate 2 is pushed, make two the first sliding blocks 11 mutually remote along the first guide rail 3 after 2 stress of support plate
From two the second sliding blocks 12 are located remotely from each other along the second guide rail 4, i.e. angle a becomes larger in Fig. 1, and angle a becomes larger so that the first strut 6 and
Two struts 7 are intended to horizontal, the i.e. reduction of support plate 2, and after support plate 2 drops to required height, guarantor's support plate 2 is not
It is dynamic, and complete to pressing pull rod 10 on the inside of lantern ring 5 so that the first turntable 9 and the second turntable 13 can not relatively rotate to support
The adjusting of the height of plate 2；
Step 3: the folding storage of bracket: after use, when needing to fold bracket, according in step 2
Described pulls out pull rod 10, first releases the locking to the first turntable 9 and the second turntable 13, so that the first turntable 9 and second
Turntable 13 is relatively rotatable to each other, to first 6 and the effect of 7 applied force of the second strut under the Gravitative Loads of support plate 2, so that
Two the first sliding blocks 11 are located remotely from each other along the first guide rail 3, and two the second sliding blocks 12 are located remotely from each other along the second guide rail 4, i.e. angle in Fig. 1
A becomes larger, and angle a becomes larger so that the first strut 6 and the second strut 7 are intended to horizontal, the i.e. reduction of support plate 2, in the reduction of support plate 2
During, as shown in Figure 1, Figure 2, Fig. 7 and Fig. 8, each telescopic sleeve 81 in speed-limiting device 8 to contract squeeze inside air
It is discharged from gas vent 82, under the action of baffle 83, the rate out of gas vent 82 is smaller, when support plate 2 declines too fast, passes through
Lantern ring 5 causes the pressure inside telescopic sleeve 81 to increase the pressure increase of telescopic sleeve 81, and gas vent 82 cannot be timely
81 inner air of telescopic sleeve is discharged, by newton third law of motion it is found that high pressure telescopic sleeve 81 inside passes through stretches
Heat-Shrinkable Tubings 81 apply opposition, to limit the decrease speed of lantern ring 5, realize the whereabouts speed limit to support plate 2, until
Support plate 2 falls to lowest part, completes the auto-folder to bracket；
During support plate 2 is highly turned up, each telescopic of the support plate 2 far from pedestal 1, in speed-limiting device 8
Pipe 81 does overhanging movement, so that the space inside speed-limiting device 8 becomes larger, internal pressure is lower, outside air from gas vent 82 into
Entering, baffle 83 rotates on the inside of the connection axial direction telescopic sleeve 81 of baffle 83 and 81 inner wall of telescopic sleeve under the action of air-flow,
It can be wherein the bead structure rolled on the inside of telescopic sleeve 81 at the free end edge of baffle 83, in this way convenient in air inlet
Preferably make 83 pivoting of baffle, gas vent 82 is not blocked, increases the air inflow of gas vent 82, thus when reducing height-regulating
Duration improves efficiency；
During the folding storage of bracket, using the self weight of support plate 2, apply the driving force of folding, and speed limit fills
Speed limit is played the role of in the whereabouts for setting 8 pairs of support plates 2, avoids the whereabouts of support plate 2 too fast, plays buffer function, improves safety,
Play a protective role to the people or object of support perimeter, and in the present invention in bracket without using the dough deformations such as spring portion
Part, therefore the service life is longer；
It, can be complete without additional power is applied to support plate 2 when highly turn down to lifter plate 2 in step 2
At, although when the height to support plate 2 is turned down, it cannot be efficient as when height-regulating, important function is played to safety,
It has also been ensured under the emergency cases such as the failure of locking mechanism 14 simultaneously, has caused security incident, reduce risk.
The basic principles, main features and advantages of the present invention have been shown and described above.The technology of the industry
For staff it should be appreciated that the present invention is not limited to the above embodiments, described in the above embodiment and specification is only this
The preference of invention, is not intended to limit the invention, and without departing from the spirit and scope of the present invention, the present invention also has

Air inflow, thus duration when reducing height-regulating；
During the folding storage of bracket, using the self weight of support plate (2), apply the driving force of folding, and speed-limiting device
(8) play the role of speed limit to the whereabouts of support plate (2), avoid the whereabouts of support plate (2) too fast, play buffer function.
