Description
Technical field
This utility model relates to sewing, cord technical field, particularly to a kind of bottom line shuttle and assembling thereof
Structure.
Background technology
On sewing, lock-type chain stitch, general locking-type line is formed when common sewing machine or cord are sewed
Mark is intertwined to form by string-hooking mechanism by bottom line and upper thread.Upper thread can by outside tower line continuous long time
Between supply, bottom line is then wound around on the peg or spindle in bobbin case, limited length, must manually after making to be finished
Change peg or spindle.Existing industrial flat bed sewing machine is required for shutting down replacing peg or spindle after a period of operation and supplements bottom line,
So can be substantially reduced the production efficiency of equipment, traditional way is to change peg or spindle with based on manual labour, because of
This labor intensity is high, and speed is slow, inefficiency.
Such as Patent No.: the shuttle structure shown in " 201320382202.8 ", the peace of the most this kind of shuttle
Dress is such, and bobbin case and peg or spindle are arranged in a storage tank, and storage tank center is provided with one and fixes axle, fixing
Shaft head is provided with necking part, and bobbin case surface is provided with a slide block that can be slided by elastic mechanism, and slide block includes base
Base plate and opening, porose on substrate plate, in necking part card hand-hole, when opening is closed, substrate plate slides and makes contracting
Cervical region offsets with bore edges at horizontal direction, makes bobbin case be limited in storage tank；When opening is pulled, base
Base plate opposite direction is slided, and makes necking part unclamp with hole, now, can be taken out with peg or spindle by bobbin case, carry out peg or spindle
Replacing；Since it is desired that pull opening, so being typically only capable to shutdown to carry out manual replacing, this reduces effect
Rate.
Utility model content
This utility model overcomes the deficiency in the presence of above-mentioned prior art, it is provided that a kind of novel bottom line
Shuttle, this shuttle is by arranging elastic rod to form elastic buttonhole at axis hole so that it is can consolidate in use
It is scheduled on bearing pin；When requiring replacement, only need to gently exert oneself just can extract；Need not need the most as before
Manually pull opening, provide a kind of faster more efficient way to the dismounting of shuttle.
The technical solution of the utility model is achieved in that
A kind of bottom line shuttle, including the bobbin case of inner hollow, bobbin case includes panel and along faceplate perimeter to face
Plate the same side extend side plate, it is characterized in that: be provided with axis hole at the heart in the panel, be horizontally set with at axis hole to
A few bearing pin to being inserted in axis hole plays the elastic rod of restriction effect.
As preferably, at axis hole, two elastic rods it are horizontally set with.
As preferably, two elastic rods are spaced and parallel setting.
As preferably, the diameter being smaller than axis hole between two elastic rods.When bearing pin is inserted permissible
Elastic rod deformation is forced to be opened.
As preferably, described elastic rod is that metal is made.
As preferably, also including substrate, substrate covers and is fixed on panel, is correspondingly provided with logical on substrate
Hole, is provided with the caulking groove communicated with through hole by through hole, and described elastic rod is arranged in caulking groove.Take this kind
Mode so that elastic rod is convenient to be installed, and can be convenient for changing when elastic failure again.
As preferably, caulking groove has two, is equipped with an elastic rod in each caulking groove.
As preferably, substrate is detachable connection with panel.Such as substrate can be screwed in face
On plate.
As preferably, also including the peg or spindle for winding bottom line, peg or spindle is arranged in bobbin case, and peg or spindle includes using
In wearing hollow windings's post of bearing pin and being arranged on the disk at hollow windings's post two ends, hollow windings's post and panel
Axis hole be oppositely arranged.
The assembling structure of a kind of bottom line shuttle, including a bearing pin being fixedly installed and bottom line shuttle as above
Son, the head of bearing pin is arranged with draw-in groove, and when bearing pin is located in axis hole, elastic rod is stuck in draw-in groove；Bobbin case
When departing from bearing pin, elastic rod deformation and disengaging draw-in groove.
Have employed design starting point of the present utility model, the theory of technique scheme and provide the benefit that:
This utility model provides a kind of novel bottom line shuttle, and this shuttle is by arranging elastic rod at axis hole
To form elastic buttonhole so that it is resistance can be overcome when assembling and pin bearing pin；When requiring replacement, only
Need to gently exert oneself just can extract；Need not need manually to pull opening the most as before, carry to the dismounting of shuttle
Supply a kind of more efficient quick way.
Specifically, the axis hole of bobbin case being directed at bearing pin and inserts, the insertion of bearing pin outwards makes elastic rod deformation
Expansion, and by the elastic force produced by bearing pin clamping.
