Specific embodiment:
The utility model is further described with specific embodiment below:
Embodiment one: referring to Fig. 1-3, such as Fig. 5-6:
A kind of wire breakage detector is provided with touch panel 2 and touching including the spacing block 1 being fixed on casing on spacing block 1
Bar 3 is provided with threading hole 4 in the outer end of feeler lever 3, and feeler lever 3 and spacing block 1 are rotation connection, and the outer end of feeler lever 3 can be in itself weight
Automatic sagging and touch panel 2 connects turning circuit under the action of power, and feeler lever 3 and touch panel 2 pass through electric wire and controller company respectively
It connects, controller judges whether to break according to the conducting situation between feeler lever 3 and touch panel 2 or the case where disconnection.
Wherein, feeler lever 3 is fixed on spacing block 1 by feeler lever screw 5, and feeler lever 3 can be around feeler lever screw 5 freely up and down
It swings；Touch panel 2 is fixed on spacing block 1 by touch panel screw 6, and touch panel 2 and touch panel screw 6 are in the conductive state, touch panel screw 6
It can be connected or insulate with sewing machine case.
Further, mounting hole 8 is provided on the spacing block 1, one end of feeler lever 3 is arranged in mounting hole 8 and passes through
Feeler lever screw 5 and spacing block 1 are rotatablely connected, and the other end of feeler lever 3 stretches out except spacing block 1.The feeler lever 3 and feeler lever screw 5
Conducting.
The touch panel 2 is L-shaped, and the vertical portion of touch panel 2 is fixed on spacing block 1 by touch panel screw 6, and horizontal position is in touching
The lower section of bar 3.
The working principle of the present embodiment:
During sewing, in the state that suture 7 is in tensioning (as shown in Figure 3), feeler lever 3 is by suture at this time
7 pulling force are in isolated state with touch panel 2 toward pull-up, feeler lever 3, i.e. circuit disconnects；In the state that suture 7 is in and loosens (such as
Shown in Fig. 2), at this time under gravity of the feeler lever 3 by itself, it is pressed on touch panel 2, feeler lever 3 and touch panel 2 are in the conductive state,
Using each needle of sewing as a cycle, each needle of sewing, the process that all tensile force changes at least once of suture 7, i.e.,
The change procedure that feeler lever 3 and touch panel 2 are all connected and disconnect at least once, is judged by controller, there is the change procedure
State, suture 7 are in the state that do not break normally.If suture 7 breaks, suture 7 without pulling force by feeler lever 3 toward pull-up, feeler lever 3
Under the gravity of itself, it is pressed on touch panel 2, feeler lever 3 and touch panel 2 are in constant conduction state, judged by controller,
Feeler lever 3 and touch panel 2 are in constant conduction state during continuous N needle, then judge that suture 7 is in broken string state.
The structure is pressed in it on touch panel 2 using the self gravity of feeler lever 3, as long as the weight of feeler lever 3 determines, suture 7
Tensile force size needed for pulling feeler lever 3 is also determining, the spring structure unlike used in the prior art, the pretightning force of spring
It is difficult to adjust, it is impossible to ensure that each device has identical pretightning force in batch production.And the structure does not use bullet
Spring can greatly promote its service life as conductor, spring it is high-frequency it is durable under, the service life is difficult to ensure.
Embodiment two: referring to fig. 4:
The basic structure of the present embodiment is the same as example 1, and difference is: the present embodiment increases pressure on feeler lever 3
Spring 9.
Shake serious phenomenon since some sewing machines exist in the process of running, and the feeler lever 3 in embodiment one according to
For gravity pressure by itself on touch panel 2, the shake of sewing machine itself can bring feeler lever 3 to shake on touch panel 2, even if suture at this time
Broken string, under the action of no suture tension, feeler lever 3 also can generate conducting with touch panel 2 and disconnect the signal of this alternation, cause
Inspection does not measure suture broken string, disabler.
For this problem, the present embodiment increases by a pressure spring 9 on feeler lever 3, and the shake for restraining sewing machine leads to feeler lever 3
Shake.As long as the tensile force of suture overcomes the gravity of feeler lever 3 and the pressure of pressure spring 9 that can pull up feeler lever 3 at this time.
Specific mounting structure is: being provided with pressure spring mounting hole on the spacing block 1 of 3 top of feeler lever, the setting of pressure spring 9 exists
In pressure spring mounting hole, one end of pressure spring 9, which is held out against, holds out against the upper plane in feeler lever 3 in the top surface of pressure spring mounting hole, the other end.
Embodiment three: referring to Fig. 7-11:
On the basis of example 1, the upper and lower position of touch panel 2 and feeler lever 3 is exchanged for the present embodiment.
Specifically:
The top of feeler lever 3 is arranged in the touch panel 2, when feeler lever 3 and touch panel 2 connect in the conductive state, not break
Linear state, feeler lever 3 is separated with touch panel 2 when being in an off state, for the state that breaks.
As shown in fig. 7, feeler lever 3 and touch panel 2 are in discrete state, i.e., under the gravity of the feeler lever 3 of the present embodiment itself
Circuit is in open circuit；As shown in fig. 6, the pulling force of suture 7 is by the past pull-up of feeler lever 3, so that feeler lever 3 under the tension of suture 7
It is contacted with touch panel 2, i.e., circuit is in the conductive state.Also with the periodic transformation of 7 tensile force of suture, so that feeler lever 3 and touching
Plate 2 is regular to be contacting and separating, and when suture 7 breaks, feeler lever 3 is in touch panel 2 always under the effect of gravity to be divided
From state, judged by controller, feeler lever 3 and touch panel 2, which are in, during continuous N needle is continuously turned off state, then judges suture 7
In broken string state.
Advantage of this embodiment is that the shake of feeler lever 3 is not even if sewing machine there are jitter phenomenon, causes feeler lever 3 to be shaken
It is enough to contact feeler lever 3 with feeler lever 2, therefore touch panel 2 can also be produced after breaking there is no suture 7 and lead on and off with feeler lever 3
The signal for this alternation opened, caused by disabler.
Specifically, the touch panel 2 is L-shaped, and the vertical portion of touch panel 2 is fixed on spacing block 1 by touch panel screw 6, horizontal
Portion is located at the top of feeler lever 3.Fluted 10 and strip groove 11 are set on the spacing block 1, and the vertical portion of touch panel 3 is arranged in groove
In 10, and the inner end of horizontal part is located in strip groove 11.
To sum up, gravity of the utility model based on feeler lever 3 itself can guarantee that lift required 7 tensile force of suture every time big
It is small consistent, and install simply, service life is secure.
Above-described embodiment is only one of preferred embodiment of the utility model, and the implementation of the utility model is not limited with this
Range, therefore: the equivalence changes that all shape, structure, principles according to the utility model are done should all be covered by the guarantor of the utility model
Within the scope of shield.
