Description
Technical field
The utility model relates to a kind of Sewing machines and backstitches touch switch.
Background technology
In traditional industrial sewing machine, automatically flat seam machine backstitch touch switch be arranged on the Sewing machines rear portion and with dial the line electromagnet and be arranged in parallel.This backstitches touch switch and comprises shake-up button, metal connecting rod and microswitch, and forms the T-shape that begins from microswitch substantially.Connecting rod extends to shank left side and concordant with the casing lower edge from microswitch.The shake-up button is installed in interlinking lever end as the surface plate of diameter 20mm.When operating personnel press when touching button, touch button and drive microswitch by connecting rod, produce the signal of telecommunication and transmit electric cabinet and backstitch electromagnet with control and carry out work.
Backstitching in the touch switch of above-mentioned structure,, influence operating efficiency so catch on cloth at work easily with the seam thing, and bar linkage structure is not attractive in appearance, also influences service life because metal connecting rod lower end connects the shake-up button of a 20mm.In addition, also usually need to be thrown light in the zone of sewing operation in the work of above-mentioned Sewing machines, this needs external power supply and light fixture usually, uses inconvenient.
Summary of the invention
A purpose of the present utility model provides a kind of compact conformation, can not disturb sewing operation backstitch the touch switch assembly.Another purpose is that throw light in the zone to sewing operation under the situation of dispense with outer connecting power and light fixture.
For achieving the above object, backstitch the touch switch assembly according to Sewing machines of the present utility model and comprise fine motion button, microswitch, housing and mounting bracket, described fine motion button and described microswitch become one and are installed in the described housing, and described housing is by being fixed on the described casing with the contiguous described mounting bracket that is provided with of the casing of Sewing machines.
The touch switch assembly that backstitches of structure is integrated in the less housing of size compact conformation like this.This assembly is installed in existing backstitching in the arrangement space of touch switch, but simple in structure and size is littler, and the Sewing machines casing that conveniently reclines is installed, and colludes cloth and seam thing in the time of can avoiding operating.
The described touch switch assembly that backstitches also comprises the fine motion guide rod that is arranged between described fine motion button and the described microswitch, and described fine motion button drives described microswitch by described fine motion guide rod.Described mounting bracket comprises horizontal component that extends perpendicular to shank and the sloping portion that extends along Sewing machines rear portion casing.
The also integrated light fixture that is equipped with in described housing.Described light fixture comprises light switch and illuminating lamp.By such layout, light fixture and touch switch are integrated in the housing, can low coverage is liftoff provide illumination to operating area, improve sewing visibility, and need not external light fixture, use convenient.
Described illuminating lamp is electrically connected to the power supply that backstitches electromagnet with by its power supply via described light switch.By such layout, the power supply that utilizes Sewing machines to carry is powered for illuminating lamp, and need not to provide in addition power supply, has further facilitated use.
Described illuminating lamp is light emitting diode (LED) illuminating lamp.The use electrical source consumption can energy savings at the LED of milliampere magnitude illuminating lamp.Described light fixture also comprises lens, with the light focusing of illuminating lamp at operating area.
Description of drawings
Describe basic structure of the present utility model and principle in detail below in conjunction with accompanying drawing:
Fig. 1 is the installation site front view that backstitches the touch switch assembly according to of the present utility model;
Fig. 2 is the decomposition view that backstitches the touch switch assembly according to of the present utility model.
The specific embodiment
As Fig. 1-shown in Figure 2,, backstitch the touch switch assembly and comprise mounting bracket 2 and be fixed on and backstitch touch switch housing 3 on the mounting bracket 2 according to an embodiment of the present utility model.Integrated fine motion button 5, fine motion guide rod 6, microswitch 7 and the light fixture of being equipped with in the touch switch housing 3 that backstitch at the cardinal principle rectangular shape.These parts can by be threaded, buckle connects or the like mode and is fixed on the housing 3.
Above backstitching the two ends bayonet socket of touch switch housing 3, be provided with the button guide groove, be used to install fine motion guide rod 6.Fine motion button 5 is buckled on the fine motion guide rod 6.When operation, when the user pressed fine motion button 5, it drove microswitch 7 by fine motion guide rod 6, backstitches signal thereby produce.This signal is delivered to electric cabinet, triggers electromagnet and backstitches operation.Certainly, also fine motion guide rod 6 can be set, and directly drive microswitch 7, but need bigger power to operate like this with fine motion button 5.The preferred setting has certain flexible fine motion guide rod 6.
Light fixture comprises lens 10, the printed circuit board (PCB) of LED lamp 9 (PCB) 8 and light switch 4 is housed on it.Lens 10 are arranged on fine motion button 5 belows.Printed circuit board (PCB) 8 is inserted in the two ends bayonet socket that backstitches touch switch housing 3.In the exemplary embodiment, printed circuit board (PCB) 8 is provided with 10 LED lamps 9.The quantity of LED lamp 9 and position can change according to actual needs.Light switch 4 is arranged on the top of fine motion button 5, is used to control the mains lighting supply of LED lamp 9.LED lamp 9 is electrically connected to the power supply that backstitches electromagnet with by its power supply via light switch 4.The LED lamp makes simple in structure in the original power supply top set power supply that backstitches electromagnet of Sewing machines like this.Perhaps, also can external mains lighting supply.Offering LED lamp 9 from power source voltage after components and parts dividing potential drop on the printed circuit board (PCB) 8 throws light on.
Make full use of original installing space according to the touch switch assembly that backstitches of the present utility model, and can have simultaneously to backstitch and touch function and illumination functions, and can not interfere the operation of Sewing machines.This assembly handled easily, effective lighting can also be carried out to the zone of sewing in energy savings and space.
Embodiment more of the present utility model below only are shown.According to the disclosed content of the utility model, those of ordinary skill in the art can easily expect some be equal to, replacement scheme, all should fall into the scope of the utility model protection.
