Abstract
The utility model provides a handle rotation device for umbrella handle-shaped kid bicycle, comprising a plurality of push handles [1], a plurality of joints [3], and a plurality of push rods [6] fixedly connected with the joints [3]. The joint [3] is rotationally connected with the push handle [1] and a locking mechanism is arranged between the joint [3] and the push handle [1]. The utility model is characterized in that the locking mechanism is formed in the way that a plurality of radial spline positioning slots with radial openings are arranged around the joint [3]. A locking block [2] is positioned in the chamber of the push handle [1] and is connected or contacted with the operating mechanism of the locking block. Through the change of the working position of the locking block, the fiction between the push handle and the joint while in relative rotation is reduced and the corresponding components are invulnerable to be damaged, thus the service life is prolonged.
Description
The utility model relates to a kind of children trolley, particularly the connecting device of the handle of umbrella-type go-cart and pushing hands bar.In the prior art, the handle of perambulator, particularly umbrella handle vehicle generally with between the push rod of go-cart is captiveed joint, can not relatively rotate, a kind of rotating umbrella handle handle be arranged in rotation process, friction back locking mutually between the tooth of tumbler and connecting element, make its tooth bar very easily damage, shorten service life.
The purpose of this utility model is to provide a kind of rotation regulating mechanism of baby carriage push handle bar of long service life.
The technical solution of the utility model is: a kind of handle rotating mechanism of umbrella-type pram, the pushing hands bar that comprises handle handle, joint, is connected to one with described joint, described joint be inserted in the described handle handle or described fitting sleeve on described handle handle and be rotatably connected between the two, be provided with lockout mechanism between described joint and the described handle handle; Described lockout mechanism is that the circumferencial direction of joint upper edge joint has a plurality of spline positioning grooves that are radial and radial opening, be provided with locking block in the inner chamber of described handle handle, described locking block has two control positioies, first control position is a lock-out state, and this moment, locking block was inserted in the spline positioning groove; Second control position is a released state, and this moment, locking block broke away from the spline positioning groove; There is the locking block stage clip that makes locking block be tending towards first control position on the top on the described locking block; Described locking block is connected with the locking block operating mechanism or contacts.
The utility model compared with prior art has following advantage:
When locking block operating mechanism operational lock piece moves, can make locking block conversion control position between first control position and second control position, conversion control position by locking block, make the little and not fragile corresponding parts of handle handle friction force when rotating, long service life with respect to joint.
The utility model will be further described below in conjunction with drawings and Examples:
Accompanying drawing 1 is the main cutaway view of locking block under released state of embodiment one of the present utility model;
Accompanying drawing 2 is the B-B direction cutaway view of accompanying drawing 1;

Accompanying drawing 8 is the D-D direction cutaway view of accompanying drawing 7; Wherein:
[1], handle handle; [2], locking block; [3], joint; [4], skewback; [5], button; [6], pushing hands bar; [7], skewback inclined-plane; [8], locking block inclined-plane; [9], skewback stage clip; [10], connect rivet; [11], locking block stage clip; [12], operating block; [13], pin; [14], guide groove; [15], spline positioning groove;
Embodiment: referring to accompanying drawing, a kind of handle rotating mechanism of umbrella-type pram, the pushing hands bar [6] that comprises handle handle [1], joint [3], is connected to one with described joint [3], described joint [3] is inserted in the described handle handle [1] or described joint [3] is enclosed within described handle handle [1] and goes up and be rotatably connected between the two, is provided with lockout mechanism between described joint [3] and the described handle handle [1];
Referring to accompanying drawing 7 and accompanying drawing 8, described lockout mechanism is that the circumferencial direction of joint [3] upper edge joint has a plurality of spline positioning grooves [15] that are radial and radial opening, is provided with locking block [2] in the inner chamber of described handle handle [1].Described locking block [2] has two control positioies, and first control position is lock-out state (referring to accompanying drawing 8 and an accompanying drawing 4), and locking block this moment [2] is inserted in the spline positioning groove [15]; Second control position is released state (referring to accompanying drawing 6 and an accompanying drawing 2), and locking block this moment [2] breaks away from spline positioning groove [15]; Described locking block [2] is gone up the top the locking block stage clip [11] that makes locking block [2] be tending towards first control position; Described locking block [2] is connected with the locking block operating mechanism or contacts.
Referring to accompanying drawing 1 and accompanying drawing 3, described locking block operating mechanism is to be provided with skewback [4] in the outer end of joint [3], the axial connection rivet [10] of the centre by being positioned at joint [3] between described skewback [4] and the described joint [3] is in axial sliding connection mutually, be with on the described connection rivet [10] that skewback stage clip [9] and its both ends are against respectively that joint [3] is gone up and skewback [4] on; Contact by the inclined-plane between described skewback [4] and the described locking block [2], described skewback [4] contacts with the button [5] of the outer end that is exposed at handle handle [1] or is connected.When pressing button [5], skewback [4] can promote locking block [2] by contacted inclined-plane and vertically move, thereby carries out evolution between first control position and second control position.The inclined-plane contact also has the gap between elimination joint [3] and the handle handle [1], makes both not feel the advantage of becoming flexible.
Described inclined-plane be engaged to rare following three kinds of forms, for example described locking block [2] is provided with locking block inclined-plane [8], described locking block inclined-plane [8] contacts with skewback [4]; Perhaps described skewback [4] is provided with skewback inclined-plane [7], and described skewback inclined-plane [7] contacts with locking block [2].Perhaps described locking block [2] is provided with locking block inclined-plane [8], and described skewback [4] is provided with skewback inclined-plane [7], and described locking block inclined-plane [8] contacts with skewback inclined-plane [7], and promptly belongs to this type of form shown in accompanying drawing 1 and the accompanying drawing 3.
