Description
Technical field
The utility model is related to racket threading equipment technical field, specially a kind of racket rotary positioning apparatus.
Background technology
Tennis racket, Badminton racket etc. have the ball of ring-type frame, are worn in frame using the racket string of tool elasticity and weave net
The striking surface of shape, and suitable degree of pulling-over state is presented in striking surface, the beginning can produce effective kicking function, and sportsman is easy to the palm
Spheroid heading after control batting, the pulling-over degree of striking surface depend on racket string in wear be configured to striking surface when, racket string
Tensile acts on formed tension numerical value, to enable wearing for racket string to knit easy and tension numerical value precisely, is usually
Racket threading operation is carried out using racket threader.
Typically in threading operation, it is required to first by frame by fixture stationary positioned, but for various multi-forms
Racket, the frame with different sizes, form mostly then is both needed to adjust the displacement of fixture for different frames, so that full
Foot difference size, the positioning of form frame, but when each displacement and positioning fixture, it is both needed to unscrew the locking of locking fixture in advance
Bolt, releases the positioning states of the fixture, when position needed for the fixture is moved to, then screws the lock bolt, makes the fixture
Positioning states are replied, it is operationally very cumbersome.
The content of the invention
In view of the above-mentioned problems, the utility model provides a kind of racket rotary positioning apparatus, its is easy to operate, is suitable for
Assemble various different sizes, the frame of form.
Its technical scheme is such, and it includes base, it is characterised in that be rotatably connected on the base by bearing
Two ends are fixed with symmetrical column on bottom plate, the bottom plate, and the column top is fixed with support block, the support block both sides
End face is provided with open slot, and the one end of connecting rod is articulated with the open slot, and the other end of the connecting rod is connected with clamping jaw,
The bottom plate between the column is provided with the kerve of elongated type, the kerve and slidably connects thread depressing mechanism, the branch
The end face center of bracer opposite side is provided with elongated guide groove, and L-shaped pushing block is slidably mounted on the guide groove, threading card
Pawl is installed on the pushing block, and the thread depressing mechanism includes briquetting, and described briquetting one end is rotatablely installed in the bottom by bearing pin
On groove, and the bottom slide guide of the bearing pin is installed in the kerve, and the other end of the briquetting is fixed with sleeve, rod set of stretching
Loaded in the sleeve, live conductor pawl is fixed at the top of the expansion link.
It is further characterized by, and the threading claw is in the arc bent along frame inner ring, and the threading claw is extremely
Few 5 tooth claws；The kerve at least two, and the thread depressing mechanism is slidably mounted on the kerve respectively.
The beneficial effects of the utility model are that being rotatably connected to two ends on bottom plate, bottom plate by bearing on base is fixed with
Support block, the one end of connecting rod is articulated with open slot, and the other end of connecting rod, which is connected with the bottom plate between clamping jaw, column, to be set
Have and thread depressing mechanism is slidably connected on the kerve of elongated type, kerve, the end face center of support block opposite side is provided with elongated guiding
Groove, L-shaped pushing block is slidably mounted on guide groove, and threading claw is installed on pushing block, and briquetting not only can be on kerve freely
Slide, and can freely be rotated on kerve by bearing pin, then can slide pushing block, edge by rotary bottom plate, in guide groove respectively
Kerve slides thread depressing mechanism and line ball pawl is raised or reduced by expansion link, so as to realize the various different sizes of assembling, shape
The frame of formula, it is easy to operate.
