Abstract
The utility model discloses a locking device of a rack, which comprises a fixed sleeve and a control rod, wherein the fixed sleeve comprises a connection seat and a base which is integrated with the connection seat, a shaft seat is arranged on the base, the connection seat is fixed on a fixed rod or a foot pipe, the control rod comprises a cam and a handle, wherein the cam is pivoted on the shaft seat, a compaction block is arranged between the cam and a mobile rod, the long diameter of the cam is larger than the distance between the cam shaft center and the compression block, the short diameter of the cam is less than the distance between the cam shaft center and the compaction block. The locking device has the advantages of more stable locking without abrading the mobile rod, which avoids the trouble of dropping a turn knob in the convey procedure. Simultaneously, the use is quietly simple and rapid and the time is saved compared with the prior turn knob which is rotated by hand.
Description
Technical field
The utility model relates to a kind of support, especially relates to a kind of locking device of support.
Background technique
The various light unitses and the audio frequency apparatus that use on the stage, generally all need support with these device support, the structure of existing support comprises base, fixing rod and motion bar, fixing rod is arranged on the base, be provided with locking device between fixing rod and the base, motion bar stretches in the fixing rod, also is provided with locking device between motion bar and the fixing rod.Existing locking device is a knob, screw thread by knob transmits thrust reaches locking to the extruding of motion bar purpose, this locking mode exists following problems: the double-screw bolt part surface of contact of one knob is less, easily motion bar is caused wearing and tearing, even push up flat, its two, after the locking, because knob double-screw bolt part and motion bar are to contact, motion bar in use has and rocks defective; Its three, in transportation process, when knob is not locked, drop out easily, cause entire bracket to use; Its four, in use needing to revolve multi-turn could lock and loosen, and allows the user feel very painstaking.
Summary of the invention
Technical problem to be solved in the utility model provide a kind of locking effect good, use the locking device of center rest more.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of locking device of support, comprise fixed cover and controlling rod, it is characterized in that described fixed cover comprises the connecting base of setting and the pedestal that is wholely set with connecting base, described pedestal is provided with axle bed, described connecting base is fixed on fixing rod or the pin pipe, comprise cam and handle on the described controlling rod, described camshaft is connected on the described axle bed, between described cam and the motion bar compact heap is set, the long diameter of described cam is greater than the distance between described cam axle center and the compact heap, and the short diameter of described cam is less than the distance between described cam axle center and the compact heap.
Described connecting base becomes cone table shape or cylindric.
Described connecting base is provided with pin hole.
Described connecting base is provided with ring shaped slot, and described ring shaped slot is set on the fixing rod wall.
On the described pedestal platform is set, described compact heap is placed on the described platform, and the relative side with cam of described compact heap is the plane, and the opposite side of described compact heap is to match with described motion bar in cambered surface or plane.
Described cam is erected at described axle bed by pin.
The lower end of described handle is provided with the strip thrust that is parallel to each other more than at least two.
Compared with prior art, the invention has the advantages that when upwards pulling handle, the cam rotation, the long diameter portion branch of cam rotates, the long diameter parts of cam separates with compact heap, the short diameter parts of cam does not produce extruding with compact heap, and motion bar can move up and down under the effect of external force like this, regulates the height of support with this.When motion bar is adjusted to suitable position, pull handle downwards, the long diameter parts of cam upwards rotates, its with the compact heap extruding, adjustable pipe is fixed.Being provided with of compact heap can increase the area of contact between itself and the motion bar, increases frictional force, and locking effect is better.This locking device can not cause wearing and tearing to motion bar, and locking is more stable, has avoided the trouble that knob drops out in the transportation process, uses very simply, quick simultaneously, and the knob of comparing in the past that rotates by hand has been saved the time.
Pedestal is provided with ring shaped slot, and ring shaped slot is set on the fixing rod wall.Pedestal is fixed on the fixing rod very easy, and assembling is also very quick on the production line.
Be placed with compact heap on the platform, the relative side with cam of compact heap is the plane, and the opposite side of compact heap is to match with described motion bar in cambered surface or plane.Compact heap can increase and motion bar between surface of contact, increase frictional force, more firm after motion bar is fixing, also avoid thrust directly to push motion bar and cause wearing and tearing.
The lower end of handle is provided with the strip thrust that is parallel to each other more than at least two.The strip thrust can increase the frictional force between handle and the hand, can not skid.
