Summary of the invention

The present invention has overcome the technical problem that exists in the above-mentioned existing technology; A kind of locking mechanism that three legs are locked in advance is provided; The utilization of this mechanism makes between photography is carried out, to move to bring the user greatest convenience, and all are pulled button and can under relaxed state, run; Save the time that button is pulled in locking, also can not cause running trouble because of stretching out of pin pipe again.

Technological scheme of the present invention is achieved in that

A kind of tripod locking mechanism of trying to be the first; Comprise center tube and three legs; It is characterized in that: rotate in the lower end of center tube and be provided with a locking plate, locking plate evenly is provided with three leaf wedge lock sheets for being horizontally disposed with on the locking plate periphery; The thickness of lock sheet is thick by being thinned to along the locking plate circumferencial direction, is provided with every leg inboard and the lock sheet locking slot of wedging mutually.

As preferably, described locking slot is arranged on the foot pad of leg bottom.

It is cross setting that button is pulled in locking on the leg in the past, and its corresponding cocked, locking action also is horizontal; Tripod with one five joint is an example, and it has the locking in 12 joints to pull button usually, and all is that horizontal Dan Li pulls button; Just to have to do earlier 12 actions of releasing in order using, to do 12 fastening actions after right rear foot tube stretches out again, if move for stealing the show; Once just must repeat to do 24 actions again; Seeming, some is wordy time-consuming, and unsatisfactory, especially can not satisfy the needs of catching a good shot fast; As preferably, described leg is to be connect by some joint pin pipe boxes to form, be provided with between the adjacent pin pipe of per two joints one be used to lock pull button, described to pull button be along the setting of pin length of tube direction, and the adjacent from top to bottom button of pulling overlaps successively.Above-mentioned pulling detained the chain button of pulling that quick locking mechanism provides vertical setting; And pull button and ride over the next one and pull and buckle for last one; As long as making to stir during the joint in locking goes up one most when pulling button, what other several linked to each other and touch pulls button and also can glide with gesture and answer gesture to fall down, with the locking joint.Otherwise and when opening the joint, pull button as long as upwards stir the next one, taking advantage of a situation up just can make all pull button all to open, thereby makes joints open.

Pull for the ease of disposable all on the leg and to tip row in and open or locking action,, pull between the button for adjacent two, pull button and ride over the next one and pull on the position of button 1/4～1/2 length for last one as preferably.

Adopted the design philosophy of the present invention of technique scheme to be:

The present invention rotates the locking plate that is provided with a tri-lobed at the tripod root of a central tube, and 120 degree are to climb; Whenever climbing lock sheet all is that single face is thinner; And tripod legs is received the length at the end entirely, adorns the position of lock sheet just, also just in time is the position of lock sheet cross-section facing to foot pad; And the locking slot of corresponding moulding crosscut shape is arranged on foot pad; Three leaf lock sheeies of locking plate are through being cooked clockwise 120 degree rotations, and the thin actinal surface of three leaf lock sheeies has got into the locking slot of three foots pad respectively, and three legs progressively thickening with the progressively inclination of groove of sheet that all be locked locked this moment; As it is just released to do counterclockwise 120 degree, and other all pull that button all can be in relaxed state and needn't be to its fastening.

Beneficial effect of the present invention is following:

1, through the utilization of this locking mechanism of trying to be the first, between photography is carried out, to move and can give the greatest convenience of user, all are pulled button and can run under the relaxed state, can not cause running trouble because of stretching out of leg again.

2, as long as counterrotating 120 degree are tried to be the first just to lock and thrown off, it is very fast again because of the stretching, extension that makes the leg shank at relaxed state that all pull button.

3, use this locking mechanism of trying to be the first after, exactly fast locking chain pull the button function all can be abandoned need not, and the time tried to be the first again another 70%.
