Background technology

General doll carriage or hand barrow all can be provided with the handle that promotes for the head of a family, the height of handle mainly is the foundation that is used as making according to the average height of being grown up, but in fact each head of a family's height must have cooresponding gap, when especially perambulator is sold to all over the world, each national height also has cooresponding gap, handle requirement for height to this type of perambulator is also inequality, but general manufacturer can't remove to assemble the handle of different length according to different selling spots, so the handle of this class regular length design and do not conform to practicality.

In order to solve the above problems, some manufacturer has developed the handle of scalable adjusting, it comprises push rod and the push-up handle with tube chamber, push-up handle directly is plugged in the tube chamber of push rod slidably, is provided with stop pin on the push-up handle slidably, has a plurality of lock holes on the push rod, during locking, the stop pin of push-up handle directly is inserted in the lock hole of a certain height and position of push rod, and when needs were regulated the relative position of push-up handle and push rod, push-up handle slided in push rod.Though this handle can be regulated length, texture ratio is more single, and operation inconvenience.

Summary of the invention

The utility model purpose is: the adjustable handle that a kind of novel structure, doll carriage easy to adjust are provided.

The technical solution of the utility model is: a kind of adjustable handle of doll carriage, comprise push rod and push-up handle, be equiped with locking piece in the tube chamber of described push-up handle, be connected with the adjusting latch hook by pin in the mounting groove of locking piece, an end of regulating latch hook is provided with lock tab, push-up handle is provided with through hole corresponding to the position of lock tab, at least be provided with two lock holes on the push rod, be provided with elastic component in the locking piece, elastic component is pressed on regulates the end that latch hook has lock tab, described adjusting latch hook has two mode of operations of the locking and unlocking, when the adjusting latch hook is in the lock state, lock tab is passed push-up handle under the effect of elastic component through hole inserts the lock hole of a certain position of push rod, when the adjusting latch hook is in released state, lock tab withdraws from all lock holes, and described push-up handle is provided with control mechanism, and control mechanism can realize regulating the release of latch hook;

Described control mechanism comprises the intraluminal traction piece that is installed in the control piece on the push-up handle and is arranged on push-up handle, one end of traction piece is connected with control piece, the mounting groove that the other end stretches into locking piece is connected with the end that the adjusting latch hook has lock tab, during the operation control piece, control piece drives the adjusting latch hook by traction piece and rotates around pin, makes lock tab withdraw from lock hole;

Described locking piece has two and be plugged in the bottom of two side levers of push-up handle respectively, and traction piece also has two, and the lower end of two traction pieces is connected with the adjusting latch hook of cooresponding locking piece respectively, and the upper end then is connected with same control piece.

The sidewall of described locking piece is provided with mounting hole, and elastic component is contained in the mounting hole, and the one end withstands the madial wall of push-up handle, and the other end withstands the adjusting latch hook;

Lock hole on the described push rod has four, and arranges at interval along the axis direction of push rod.

The utility model advantage is:

1. when regulating handle length, as long as operate control piece earlier, control piece drives the adjusting latch hook by traction piece and rotates around pin, make lock tab withdraw from lock hole, realize regulating the release of latch hook, spur or advance push-up handle again, when the lock hole of the arbitrary position on the through-hole alignment push rod of push-up handle, regulating latch hook rotates around pin under the elastic force effect of elastic component, the through hole that makes the adjusting projection pass push-up handle inserts this lock hole, so just realized the locking of push rod and handle, so the utility model is regulated very convenient.

2. the lock hole on the push rod is a plurality of in the utility model, so this handle has many grades of regulatory functions, uses with the people who is fit to different heights, has enlarged suitable crowd greatly.
