Description

Can stepless adjustment and the tripod of auto lock

The utility model relates to a kind of support that is used to support photography, shooting and mapping equipment, particularly a kind of can stepless adjustment and the tripod of auto lock.

Tripod is being used aspect photography and the shooting widely, tripod commonly used at present has following shortcoming: the mode that its supporting leg moves is close to two or three fixed boss by a controllable movable block and realizes, therefore this tripod provides two specific or three angles, limited the degrees of freedom of supporting leg, in addition, general photography, shooting with the frame head of tripod be circular arc or step type, and the frame head of surveying and drawing with tripod is the plane, and therefore two kinds of tripods can not be used with.

The purpose of this utility model provide a kind of supporting leg degrees of freedom big and can stepless adjustment and auto lock tripod.

The technological scheme that realizes above-mentioned purpose is: a kind of can stepless adjustment and the tripod of auto lock; have three supporting legs; supporting leg adjustment mechanism; the lowering or hoisting gear of fixedlying connected with supporting leg adjustment mechanism; the top of lowering or hoisting gear is equipped with conversion adapter; supporting leg adjustment mechanism comprises the housing that is hinged with the circular arc joint; the housing inboard is fixed with stop screw; this stop screw leans on mutually with the step of circular arc joint; be provided with the retaining plate of trough of belt in the housing; have roller in the groove of retaining plate, this roller can contact with the arc surface of circular arc joint, is provided with stage clip between retaining plate and the housing; this stage clip one end props up housing; the other end props up retaining plate, and the outside of housing is equipped with presses hand, and this retaining plate of pressing in hand and the housing flexibly connects.

After adopting technique scheme; tripod has supporting leg adjustment mechanism; retaining plate in the supporting leg adjustment mechanism, stage clip, roller and circular arc joint form a unidirectional self-lock mechanism; make supporting leg can only be inwards movable and outwards activity; press the active force that hand overcomes stage clip and make roller leave the arc surface of circular arc joint when pinning with hand; supporting leg just can freely loose, and moving range can stepless adjustment, and is very convenient.This structure makes the tripod user as long as a manual control is pressed the various states that hand just can be controlled supporting leg, makes the user the energy flower on taking pictures or photographing they be got twice the result with half the effort.

The embodiment who provides below in conjunction with accompanying drawing is described in further detail the utility model.

Fig. 1 is a perspective view of the present utility model;

Fig. 2 is the enlarged diagram of analysing and observe of supporting leg adjustment mechanism among Fig. 1;

Fig. 3 is the enlarged diagram of analysing and observe of lowering or hoisting gear among Fig. 1;

Fig. 4 is the enlarged diagram of analysing and observe of claw among Fig. 1.

As Fig. 1; shown in 2; a kind of can stepless adjustment and the tripod of auto lock; have three supporting legs 4; supporting leg adjustment mechanism 1; the lowering or hoisting gear 2 of fixedlying connected with supporting leg adjustment mechanism 1; the top of lowering or hoisting gear 2 is equipped with conversion adapter 5; supporting leg adjustment mechanism 1 comprises the housing 1-6 that is hinged with circular arc joint 1-5; housing 1-6 is hinged by mandrel 1-2 and circular arc joint 1-5; housing 1-6 inboard is fixed with stop screw 1-4; this stop screw 1-4 leans on mutually with the step of circular arc joint 1-5; be provided with the retaining plate 1-11 of trough of belt in the housing 1-6; have roller 1-7 in the groove of retaining plate 1-11, this roller 1-7 can contact with the arc surface of circular arc joint 1-5, is provided with stage clip 1-8 between retaining plate 1-11 and the housing 1-6; this stage clip 1-8 one end props up housing 1-6; the other end props up retaining plate 1-11, and the outside of housing 1-6 is equipped with presses hand 1-9, and this is pressed hand 1-9 and flexibly connects by the retaining plate 1-11 in pin 1-10 and the housing 1-6.Between housing 1-6 and the circular arc joint 1-5 nylon washer 1-3 phase contrast is arranged, mandrel 1-2 two ends are rotary with screw 1-1, and this screw 1-1 can adjust the damping force between housing 1-6 and the circular arc joint 1-5, and stop screw 1-4 can limit the rotation angle of supporting leg 4.Housing 1-6, stage clip 1-8, retaining plate 1-11, unidirectional self-lock mechanism of the common formation of roller 1-7 and circular arc joint 1-5, make supporting leg can only be inwards movable and outwards activity, when needing to regulate the angle of supporting leg 4, as long as pin the active force of pressing hand 1-9 and overcoming stage clip with hand, make retaining plate 1-11 live outer moving, roll the arc surface that 1-7 just leaves circular arc joint 1-5 in the groove of retaining plate 1-11, housing 1-6 just can rotate around circular arc joint 1-5, thereby make the supporting leg 4 of fixedlying connected with housing 1-6 can be free movable, the user can regulate the angle of supporting leg 4 as required.

As shown in Figure 3, lowering or hoisting gear 2 is by the lifting bar 2-1 that is fixed with tooth bar 2-9, pedestal 2-6, gear shaft 2-5 and the handle 2-3 of fixedlying connected with gear shaft 2-5 form, lifting bar 2-1 is inserted in the center hole of pedestal 2-6, on the center hole, the lower end respectively has a rubber ring 2-2 to match with lifting bar 2-1, there is flange 2-7 to match on the lifting bar 2-1 with groove 2-8 on the gear shaft 2-5, gear shaft 2-5 is meshed with tooth bar 2-9 on the lifting bar 2-1, handle 2-3 is fixedlyed connected with gear shaft 2-5 by pin 2-4, as long as handle with sleeve 2-3, gear shaft 2-5 is rotated, gear shaft 2-5 drives the tooth bar 2-9 that is meshed with it again and moves up and down, thereby makes the lifting bar 2-1 lifting of fixedlying connected with tooth bar 2-9.These lowering or hoisting gear 2 compact structures are particularly suitable on the little frame head in frame head space, owing to also have two rubber ring 2-2 to cooperate, in use feel is also fine.

Shown in Fig. 1,4, the lower end of supporting leg 4 is fixed with claw 3, claw 3 comprises sole cover 3-3 and sole 3-4, sole cover 3-3 is enclosed within on the axle of sole 3-4, also be rotary with screw 3-1 on the axle of sole 3-4, be provided with spring 3-2 between this screw 3-1 and the sole cover 3-3, the side of sole 3-4 has pin nail 3-6, and opposite side is equipped with rubber 3-5.Can change one side of landing ground during use by surface state, there is skewed slot to match on the sole 3-4 with sole cover 3-3, during conversion, 3-4 presses downwards sole, screw 3-1 pressure spring 3-2, when sole cover 3-3 and sole 3-4 cooperate skewed slot to break away from the time, rotation sole 3-4, turn over 180 and loose one's grip when spending, sole 3-4 automatically resets under the active force of spring 3-2 and compresses.This structure operation is simple, and adaptive capacity is strong, can be in various ground condition, and various angles provide solid and reliable support, are the indispensable annexes of professional person.

As shown in Figure 1; supporting leg 4 is made up of outer foot tube 4-1, internal pin 4-3 and adapter 4-2; internal pin 4-3 is enclosed among the outer foot tube 4-1; taking over the lower end that 4-2 is spun on outer foot tube 4-1, fixedlys connected with the housing 1-6 of supporting leg adjustment mechanism in the upper end of outer foot tube 4-1, and internal pin 4-3 top is enclosed among the outer foot tube 4-1; regulate the length that internal pin 4-3 stretches out outer foot tube 4-1 as required; just regulated the length of supporting leg 4, after mixing up, rotation is taken over 4-2 and is compressed internal pin 4-3 with fixing.The external diameter of sole 3-3 in the hole of internal pin 4-3 and the claw 3 matches, and rivets tightly with rivet.

The lifting bar 2-1 and the tooth bar 2-9 of conversion adapter 5 of the present utility model and lowering or hoisting gear 2 are pulled down, promptly can be used as the tripod of mapping usefulness.Thereby make the utility model both be applicable to shooting or photography, be applicable to mapping again, enlarged using scope.
