Description
Technical field
The utility model relates to tripod universal structure technical field, axle construction during particularly a kind of tripod is universal.
Background technique
Tradition foot rest axis is adjusted up and down only, shooting for microshot and special angle has narrow limitation, and existing universal axis can cause axis to do unnecessary displacement when locking and unclamping the adjustment of doing in the vertical plane, the composition when thereby influence is taken, and the locking of the rotation in the universal axis vertical plane is by knob controlling with unclamping, when not locking fully, easily cause the damage of dentate body, in order to improve known above-mentioned every defective, the utility model is to provide a kind of universal middle axle construction of foot rest, the universal adjustment of axis can be realized, when adjusting, other orientation can not be influenced.
Summary of the invention
The purpose of this utility model is to solve deficiency of the prior art, provides a kind of axis universally to adjust, and do not influence when adjusting the tripod in other orientation of axis universal in axle construction.
To achieve these goals, the utility model can be decomposed into three funtion parts, promptly comprises the locking of rotation and locking, axis body in the rotation of mechanism's horizontal plane and locking, the mechanism's vertical plane and loosens.
The rotation of mechanism's horizontal plane and locking: solid of rotation is arranged in the upper body by cone match, by the locking that is positioned at down the knob on the body and the rotation and the locking that loosen the horizontal plane of realizing solid of rotation.
Rotation and locking in mechanism's vertical plane: cooperate the outer ratchet wheel that is located on the mandrel and be set in the clutch of the inner ratch gear on the supporting base by the inclined-plane, thereby effectively control the orientation of supporting base in vertical plane, and can bear certain external force moment.
The locking of axis body with loosen: by perforating on the supporting base be positioned at the acting in conjunction of the knob on the supporting base, may realize to the effective locking of axis body with loosen.
Axle construction during a kind of tripod is universal, the locking and the loosening mechanism that comprise rotation in the rotation of horizontal plane and lockable mechanism, the vertical plane and lockable mechanism, axis body, the rotation of horizontal plane and lockable mechanism are fixed on the tripod platform, by the folder bearing be sheathed on solid of rotation fixing with vertical plane in rotation is connected with lockable mechanism, pass through to press from both sides bearing hole simultaneously and fix universal axis.
The rotation of described horizontal plane and lockable mechanism comprise that solid of rotation is arranged in the foot rest upper body by cone match, upper and lower displacement by back-up ring restriction solid of rotation, can only rotate, and the knob that is positioned at down on the body acts on the solid of rotation by briquetting, and knob loosens, and solid of rotation can rotate freely, the knob locking, then solid of rotation is locked, can not rotate, thus the adjustment in first orientation of realization axis.
Rotation in the described vertical plane and lockable mechanism comprise that the folder bearing is sheathed on solid of rotation, wear two outer cone tooths in the folder bearing, more than three be located on the mandrel, when under the cam member effect, locking, promoting two outer cone tooths by briquetting moves forward, with the conical tooth engagement in the folder bearing, under the effect of locking component, two outer cone tooths are embraced to mandrel, have eliminated the gap between each part, thereby have fixed the spatial position of folder bearing, reached and in vertical plane, rotated and effective locking, the folder bearing can only be rotated with respect to solid of rotation, and can not move horizontally, thereby realizes the adjustment in second orientation of axis.
The locking of described axis body and loosening mechanism comprise that axis is arranged in the hole of supporting base, act on the axis by briquetting by the knob that is positioned at the supporting base middle part, during the knob locking, axis is then effectively locked, when knob loosens, axis then can axially be adjusted along the hole, thereby realizes the adjustment in the 3rd orientation of axis.
Axle construction during a kind of tripod is universal, comprise foot rest upper body, following body, a solid of rotation, a grip slipper, a mandrel, two outer cone tooths and a Middle shaft assembly, upper body, following body, a solid of rotation are in Middle shaft assembly, and mandrel, two outer cone tooths are in grip slipper.
Described grip slipper and Middle shaft assembly are rotation and lockable mechanism, the locking of axis body and the parts of loosening mechanism in the rotation on fixed level plane and lockable mechanism, the vertical plane.
Beneficial effect
Axle construction during the tripod that the utility model provides is universal can realize the universal adjustment of axis, does not influence the universal middle axle construction of tripod in other orientation of axis when adjusting.

Embodiment
Fig. 1 is the general illustration of the universal middle axle construction of the utility model tripod.
For convenience of explanation, the utility model can be decomposed into three funtion parts, promptly comprises the locking and the loosening mechanism of rotation in the rotation of horizontal plane and lockable mechanism, the vertical plane and lockable mechanism, axis body.
Axle construction comprised the upper and lower body of foot rest, a solid of rotation, a grip slipper, a mandrel, two outer cone tooths and a Middle shaft assembly during tripod was universal.
Grip slipper and Middle shaft assembly comprise rotation and lockable mechanism, the locking of axis body and the parts of loosening mechanism in the rotation on fixed level plane and lockable mechanism, the vertical plane.
The rotation of horizontal plane and keying structure, as Fig. 2, shown in Figure 3:
Solid of rotation 1 is arranged in the foot rest upper body 2 by cone match, upper and lower displacement by back-up ring 3 restriction solid of rotation, can only rotate, and the knob 4 that is positioned at down on the body 6 acts on the solid of rotation 1 by briquetting 5, and knob 4 loosens, and solid of rotation 1 can rotate freely, knob 4 lockings, then solid of rotation 1 is locked, can not rotate, thus the adjustment in realization axis 12 first orientation.
Rotation and keying structure in the vertical plane.As Fig. 4, Fig. 5, shown in Figure 6:
Folder bearing 7 is sheathed on solid of rotation 1, wear two outer cone tooths 8 in the folder bearing 7, more than three be located on the mandrel 9, when under cam member 10 effects, locking, promoting two outer cone tooths 8 by briquetting 11 moves forward, with the conical tooth engagement in the folder bearing 7, under the effect of locking component, two outer cone tooths 8 are embraced to mandrel 9, have eliminated the gap between each part, thereby have fixed the spatial position of folder bearing 7, reached and in vertical plane, rotated and effective locking, folder bearing 7 can only be rotated with respect to solid of rotation 1, and can not move horizontally, thereby realizes the adjustment in 12 second orientation of axis.
The locking of axis body with loosen structure, as shown in Figure 7:
More than; axis can be realized the adjustment in level, vertical and flexible three orientation in this mechanism; promptly realized the function of universal axis; and do not do any unnecessary displacement; the adjustment in one of them orientation does not influence other orientation; and by cam-locked with loosen; the locking of Vertical direction is finished with loosening by cam member; have only two clear and definite location; promptly can only locking or loosen fully; avoid boring that tooth does not mesh fully and the profile of tooth that causes is damaged, and by the safety lock protection, avoid misoperation and machinery equipment is damaged.Play the effect of protection foot rest body.
