Description
Technical field
The present invention relates to support technology field, more particularly to a kind of foldable A-frame.
Background technology
At present, in the market is many for camera, the tripod of video camera, and the main function of tripod is to fix camera
Material and regulation shooting angle, it is either all very important for amateur user or its effect of professional user.General tripod
Body is directly connected with pin axle sleeve, by the swing of body connecting portion, directly adjusts putting for tripod.It can not roll over
Folded to use, space-consuming is big, and inconvenience is brought to user's trip.
The content of the invention
It is an object of the invention to overcome the shortcomings of above-mentioned technology, and provide a kind of foldable A-frame.
The present invention to achieve the above object, using following technical scheme：
A kind of foldable A-frame, it is characterised in that：Including ball seat, three supporting legs, lock sleeve, locking jaw and connection
Bar, the ring week of the ball seat are uniformly provided with three grooves, and the top of three supporting legs is hinged by hinge and inside grooves respectively, and three
The top of individual supporting leg is respectively semicircle, and V-shaped groove is had on the top of three supporting legs, and the locking jaw is uniformly fixed respectively
On the lock sleeve, the connecting rod is fixed on the bottom of the ball seat, and the lock sleeve is enclosed in the connecting rod, described
The side wall of groove is provided with locking jaw via, and the locking jaw passes through from locking jaw via, the horizontal stroke on the top of the locking jaw
Rectangular triangle in the street.
Preferably, the plane on the top of the groove and the diameter parallel of ball seat vertical direction, the plane and ball seat of bottom
The axis of vertical direction is in obtuse angle.
The beneficial effects of the invention are as follows:Relative to prior art, the present apparatus is simple in construction, three supporting legs can the above be folded into
In groove, it is hidden into ball seat, is so readily transported carrying, can be flipped out when in use from groove, forms triangle branch
Support structure, due to special locking mechanism, self-locking is formed when locking jaw is entered in V-shaped groove during bending downwards, can be prevented
Three supporting legs oneself rotate.

Embodiment
Below in conjunction with the accompanying drawings and preferred embodiment describes the embodiment of the present invention in detail.As Figure 1-Figure 8, one
The foldable A-frame of kind, including 1, three supporting leg 2 of ball seat, lock sleeve 3, locking jaw 4 and connecting rod 5, the ring of the ball seat
Week is uniformly provided with three grooves 6, and the top of three supporting legs is hinged by hinge 7 with inside grooves respectively, the top of three supporting legs
Respectively semicircle, semicircle can be realized and is rotatably assorted with ball seat, spacing in order to be carried out to supporting leg, on the top of three supporting legs
V-shaped groove 8 is had, the locking jaw is uniformly fixed on the lock sleeve respectively, and the connecting rod is fixed on the ball seat
Bottom, certain gap is left between connecting rod and axle bed, the lock sleeve is enclosed in the connecting rod, and lock sleeve can be
Slided up and down in connecting rod, the side wall of the groove is provided with locking jaw via 9, and locking jaw via is corresponding with locking jaw, all for
Three, when lock sleeve upward sliding, the locking jaw passes through from locking jaw via, exposes from locking jaw via, now
Locking jaw can be entered in V-shaped groove if the V-shaped groove just rotating knife on the supporting leg top position, so as to be locked to supporting leg
Tightly.The rectangular triangle in rank street face on the top of the locking jaw, top is parallel surface, is contacted with locking jaw via on groove
Position is an inclined-plane, and locking jaw can be retracted from locking jaw via when retracting lock sleeve downwards, consequently facilitating withdrawing three
Supporting leg.
The plane on the top of the groove and the diameter parallel of ball seat vertical direction, plane and the ball seat vertical direction of bottom
Axis in obtuse angle.The structure can ensure the steadiness of three supporting legs.
During expansion, locking jaw is stuck in V-shaped groove, and locking jaw withstands V-shaped groove all the time under the action of the spring, ensures three branch
It is indeformable that leg forms gusseted.
During withdrawal, three supporting legs are moved upwards, and supporting leg overcomes the elastic force of spring to be recovered to upwards in groove.
The present apparatus is simple in construction, three supporting legs can the above be folded into groove, be hidden into ball seat, be so readily transported and take
It band, can be flipped out when in use from groove, form triangular support configurations, due to special locking mechanism, downwards bending
When form self-locking when locking jaw is entered in V-shaped groove, can prevent three supporting legs oneself from rotating.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
