Detailed description of the invention
With reference to Fig. 1, a kind of doll carriage leg is by bending control apparatus, comprise for the S. A. 10 of leg by rotating, be fixedly installed on the adjusting joint 1 at S. A. 10 two ends, one is installed in go-cart in order to install the arthrodesis seat 2 of adjusting joint 1, adjusting joint 1 can rotate by opposed articulation permanent seat 2, a catch gear is provided with between adjusting joint 1 and arthrodesis seat 2, catch gear comprises one can along the locking piece 3 of the axial motion of adjusting joint 1, the release mechanism that one control locking piece 3 moves, locking piece 3 is provided with a snap device to lock the rotation between adjusting joint 1 and arthrodesis seat 2.
After taking above-mentioned structure, when needing the angle regulating leg to lean on, a hand shift release mechanism makes locking piece 3 depart from the contact with arthrodesis seat 2, another hand rotatable leg, by suitable angle, is unclamped release mechanism and is made the snap device of locking piece 3 and arthrodesis seat 2 clamping to lock the rotation between adjusting joint 1 and arthrodesis seat 2.
As preferred embodiment, snap device is one be arranged on the ratchet structure of locking piece 3 near arthrodesis seat 2 side, the pawl structures 21 matched with ratchet structure that arthrodesis seat 2 inside is provided with some annular distribution, ratchet structure can pawl structures 21 unidirectional rotation relatively.Wherein, ratchet structure comprises the ratchet 31 of some annular distribution, the plane of an inclination is arranged in the front of ratchet 31 and a vertical plane is arranged at its back side, an inclined-plane matched with the front of ratchet 31 is arranged in the front of pawl structures 21 and a vertical plane is arranged at its back side, the multi-angle leaned on for realizing leg regulates, ratchet 31 continuous distribution is on a periphery of locking piece 3, in like manner pawl structures 21 continuous distribution is on a periphery of arthrodesis seat 21, and ratchet 31 is consistent with the quantity of pawl structures 21, the front of ratchet 31 and the front face of pawl structures 21, the back side of ratchet 31 and the rear-face contact of pawl structures 21, and the concrete quantity of ratchet 31 and pawl structures 21 and size can determine according to the actual requirements.Automatically reset for convenience of locking piece 3 and keep the contact of ratchet structure and pawl structures 21, locking piece 3 is provided with a link slot 33 away from the side of arthrodesis seat 2, link slot 33 is provided with a spring 4, the side of spring 4 is arranged on adjusting joint 1, the contact between spring 4 compact lock gripping members 3 and arthrodesis seat 2.
After taking above-mentioned structure design, the inclined-plane in the front of ratchet 31 and pawl structures 21 makes between locking piece 3 and arthrodesis seat 2 can around a direction unidirectional rotation, and ratchet 31 and the vertical plane in the front of pawl structures 21 make can not rotate backward when locking piece 3 contacts with arthrodesis seat 2.
Certainly, according to actual conditions, the projection of some circle distribution that locking piece 3 is arranged of can also taking buckle structure matches with the shrinkage pool of some circle distribution that arthrodesis seat 21 is arranged the mode of clamping, inclined-plane is arranged in a certain face of its protrusions, accordingly, when certain one side that shrinkage pool is corresponding is arranged to cambered surface to make locking piece 3 contact with arthrodesis seat 2, locking piece 3 can only opposed articulation permanent seat 2 unidirectional rotation.
For realizing the unidirectional rotation between adjusting joint 1 and arthrodesis seat 2, the lateral wall of locking piece 3 is provided with some projections 32, the madial wall of adjusting joint 1 is provided with some screens grooves 11 matched with projection 32, such locking piece 3 can only move along the axial direction of adjusting joint 1, and can not rotate in relative adjustment joint 1.
For convenience of operation and the locking state removed between locking piece 3 and arthrodesis seat 2, release mechanism comprises the steel cable 6 that is movably arranged on pull bar 5 in the middle part of S. A. 10, one end is connected with pull bar 5, and the other end of steel cable 6 is arranged on locking piece 3.
As preferred embodiment, one end of steel cable 6 is provided with a steel ball 61, and release mechanism also comprises the sleeve 7 of an installation steel ball 61, locking piece 3 is provided with the mounting groove 34 of an installing sleeve 7; One end of steel cable 6 is provided with a coupling link 8, and the centre of coupling link 8 offers a connecting bore 81, and connecting bore 81 coordinates a screw rod to be connected on pull bar 5 by coupling link 8; The middle part of S. A. 10 is provided with a sliding tray 9, pull bar 5 is provided with mounting hole 51, and mounting hole 51 coordinates a screw rod pull bar 5 slip to be suspended on sliding tray 9.So only locking piece 3 just need be made easily to depart from the contact of arthrodesis seat 2 with pulling a lower link 5 thus locking piece 3 can rotate backward by opposed articulation permanent seat, and after releasing lever 5, under the effect of spring 4, locking piece 3 and arthrodesis seat 2 close contact make locking piece 3 not rotate backward by opposed articulation permanent seat 2.
The specific operation process of this product is as follows: when leg folds by bending, a hand pins pull bar 5, and pull bar 5 is toward intermediate active, and then drive locking piece 3 to throw off arthrodesis seat 2 by steel cable 6, another hand leans on by leg downwards, thus completes folding.Open leg by time, a direct hand is up carried, and leg is by just automatically opening.
In sum, this product is by the rotation locked between adjusting joint 1 and arthrodesis seat 2 of ratchet 31 and pawl structures 21, and locking effect is good, and can carry out the locking of multi-angle, and easy to use, structure is simple.
Certainly, the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
