Description
Technical field
The present invention relates to luggage accessory technical field more particularly to a kind of stepless locking case drawbars.
Background technology
Luggage is a kind of using very universal tool in living as daily people, especially with the luggage of pull rod.It is existing
The pull rod being made of handle, fixing pipe and telescopic moving pipe, wherein fixing pipe are generally comprised by the luggage for carrying pull rod in the market
It is provided between telescopic moving pipe for limiting location structure when telescopic moving pipe adjusts rod length.The location structure
The convex block and card slot generally positioned respectively by being provided with mutual cooperation clamping in fixing pipe and telescopic moving pipe.Although should
Kind can also realize the adjusting to rod length using the trolley case of the location structure form of convex block and card slot, but due to pull rod
In card slot be it is spaced, thus cause trolley case cannot be adjusted to according to the needs of users well one consumption
Person uses most comfortable rod length.
Invention content
It is an object of the invention to overcome the case drawbar of the prior art due to can not achieve stepless locking, therefore cannot make
Trolley case can be adjusted to a consumer using the deficiency of most comfortable rod length according to the needs of users, provide one
Kind can meet stepless locking case drawbar of the different consumers to rod length demand.
In order to achieve the above object, the present invention adopts the following technical scheme that：
A kind of stepless locking case drawbar, including fixed link, telescopic rod, handle and control assembly, wherein telescopic rod can
Telescopic slide it is arranged in the fixed link inner cavity, the fixed link intracavity sidewall is equipped with several tooth sockets, and the tooth socket is in
Annular, several tooth sockets are vertically uniformly arranged；Set on the telescopic rod there are two pitch wheel, the gear with
The tooth socket cooperates, and two gears are separately positioned on respective gear shaft, the two of the gear on the gear shaft
Side has been respectively fixedly connected with mounting rod；The control assembly includes button, drive link and latch segment, and the latch segment is arranged in institute
The both ends of gear shaft are stated, the latch segment is mutually clamped locking with the tooth socket, and the drive link is arranged in the mounting rod,
One end of the drive link, which is equipped with, touches block, and the other end of the drive link connects the button, the shake-up block and the lock
There is the inclined-plane being bonded to each other between tight block；When making drive link push by lower button, the shake-up block of the drive link lower end pushes away
It moves the latch segment to be caught in the tooth socket of fixed link side wall, when button, which bounces back, to be resetted, the shake-up block of drive link lower end is multiple simultaneously
Position simultaneously drives the latch segment to bounce back so that latch segment is detached with tooth socket.
Further, the gear is an integral molding structure with gear shaft.
Further, the latch segment is tapered, and the head of the latch segment is in arc surface.
Further, further include several mounting brackets for installing the mounting rod, the mounting bracket setting is in institute
It states in telescopic rod inner cavity, the mounting bracket includes outline border and link, and the outline border fits with the telescopic rod inner cavity, institute
It is in X-shaped to state link, and the link is equipped with the jack for being inserted into the mounting rod.
Further, the mounting bracket is polypropylene mounting bracket.
After adopting the above technical scheme, the invention has the advantages that：
1, when button is in releasing orientation, telescopic rod is connect by gear thereon with fixed link Telescopic sliding.When
When button is pressed, the shake-up block of drive link lower end moves down, and touches block slope driving latch segment and is caught in the tooth socket of fixed link side wall,
So that fixing locking between telescopic rod and fixed link, stepless locking is realized so that trolley case can come according to the needs of users
It is adjusted to a consumer and uses most comfortable rod length；When button, which bounces back, to be resetted, the shake-up block of drive link lower end moves up,
So that latch segment retraction so that latch segment is detached with tooth socket, and telescopic rod can pass through gear thereon and the scalable cunning of fixed link
Dynamic connection.
2, due to the gear size very little in telescopic rod, gear and gear shaft are made of one structure, gear can be increased
With the intensity of gear shaft, and convenient for manufacture installation.
3, due to having gap, latch segment that may be stuck in when stretching out between two upper and lower tooth sockets between tooth socket and tooth socket,
Latch segment is tapered and head is in arc surface, can be imported in the tooth socket on fixed link intracavity sidewall in order to latch segment so that
Telescopic rod and fixed rod locking.
4, since telescopic rod is thinner, its bending resistance is weaker after telescopic rod pull-out, and toughness is poor, is susceptible to bending
Situation.Mounting bracket is set in telescopic rod, and the outline border of mounting bracket can increase the thickness of telescopic rod corner, therefore improve and stretch
The bend resistance intensity of contracting bar, to improve toughness of the pull rod in elongation.On the other hand, four mounting rods of mounting bracket pair have
The effect of guide-localization.
5, polypropylene has good intensity, rigidity, hardness and heat resistance, and of low cost, is manufacture mounting bracket
Preferred material.
