Abstract

The utility model provides a rotary pushing handle mechanism for pram, comprising a push handle (8) shaped like an umbrella handle and a push rod (1), the rear part of which is inserted in a push handle sheath (4) at the front part of the push handle (8). The push rod (1) in the cavity of the push handle sheath (4) is provided with a retaining groove (6), and the push handle sheath (4) is provided with a retaining pin (9), wherein the retaining pin (9) is positioned in a retaining groove (6). A locking mechanism is arranged between the push rod (1) and push handle sheath (4) to lock the relative location of the push rod (1) and push handle sheath (4). When the locking mechanism is unlocked, the push handle sheath performs a circular motion around the push rod. The utility model has the characteristics of simple structure and convenient operation.

Description

The rotation handle mechanism of perambulator

Technical field

The utility model relates to the handle on a kind of perambulator, particularly perambulator.

Background technology

In the prior art, the handle of the handle of perambulator, particularly umbrella handle vehicle generally can not rotate, and this uses very inconvenient for go-cart person of differing heights and speech, and long-time same direction handle defensive position can fatigue.

Summary of the invention

The purpose of this utility model is to provide a kind of rotation handle mechanism of perambulator simple in structure, and this handle can rotate with respect to push rod.

The technical solution of the utility model is: a kind of rotation handle mechanism of perambulator, the handle, the push rod that comprise the handle of umbrella shape, the rear portion of described push rod is inserted in the handle cover of front portion of handle, push rod in the inner chamber of described handle cover is provided with position-limited trough, this position-limited trough is around external peripheral surface one circle of described push rod, described handle puts and is provided with position-limitting pin, and this position-limitting pin is positioned at described position-limited trough; Also be provided with the lockout mechanism of the relative position that is used to lock push rod and handle cover between described push rod and the handle cover.

The utility model compared with prior art has following advantage:

After making the lockout mechanism release, the handle cover can be made circular movement around push rod, and position-limitting pin is positioned at the position-limited trough of annular, makes the handle cover to make circular movement and can not make axial motion, then handle can rotate around push rod, and it is spacing to make when being locked in different positions this rotation be prevented.Of the present utility model simple in structure, easy to operate.

Accompanying drawing 1 is structure master's cutaway view of the present utility model;

Accompanying drawing 2 is the A-A place section-drawing of accompanying drawing 1; Wherein:

[1], push rod; [2], spring leaf; [3], stop pin; [4], handle cover; [5], fixing pin; [6], position-limited trough; [7], spacing head; [8], handle; [9], position-limitting pin; [10], button;

The specific embodiment

Referring to accompanying drawing 1 and accompanying drawing 2, a kind of rotation handle mechanism of perambulator, the handle [8], the push rod [1] that comprise the handle of umbrella shape, the rear portion of described push rod [1] is inserted in the handle cover [4] of front portion of handle [8], push rod [1] in the inner chamber of described handle cover [4] is provided with position-limited trough [6], this position-limited trough [6] that is to say to be the annular shown in accompanying drawing 1 and the accompanying drawing 2 that around external peripheral surface one circle of described push rod [1] slot cross-section of this position-limited trough [6] is semicircle.Described handle cover [4] is provided with position-limitting pin [9], and this position-limitting pin [9] is positioned at described position-limited trough [6]; Also be provided with the lockout mechanism of the relative position that is used to lock push rod [1] and handle cover [4] between described push rod [1] and the handle cover [4].

Be fixed with spacing head [7] in the rear portion inner chamber of described push rod [1], as shown in Figure 1, push rod [1] and spacing head [7] fixed by fixing pin [5].The rear portion of this spacing head [7] protrudes from the rear end oral area of push rod [1], and described position-limited trough [6] is positioned on the described spacing head [7].

Described position-limitting pin [9] is fixed on the handle cover [4], the middle part of described position-limitting pin [9] is arranged in described position-limited trough [6], make position-limitting pin [9] limit between handle cover [4] and the push rod [1] and move axially, but can relatively rotate between handle cover [4] and the push rod [1].

Described lockout mechanism is that push rod [1] is provided with elastomeric stop pin [3], this stop pin [3] is inserted in the lock hole of handle cover [4] after passing hole on the push rod [1], described handle cover [4] is provided with knob [10], and this button [10] is aimed at described stop pin [3].Described stop pin [3] is arranged on the spring leaf [2], and this spring leaf [2] is arranged in the inner chamber of push rod [1], and described stop pin [3] has two at least, and the lock hole of described handle cover [4] has one, and described button [10] is aimed at the lock hole on the handle cover [4].In accompanying drawing 1, when pressing the button [10], can make the lock hole on a stop pin [3] the disengaging handle cover [4], then can relatively rotate between handle cover [4] and the push rod [1], after rotating 180 degree, another stop pin [3] enters in the lock hole on the handle cover [4], has finished locking again, and is then locked between handle [8] and the push rod [1].Described stop pin [3] or lock hole can be provided with a plurality of, make that handle [8] can be locked on a plurality of different positions.
