Abstract
The utility model is related to a kind of travel switch, including housing, it is characterised in that：A push rod being movably arranged in housing, a T-shape lance being movably arranged in housing, an adjusting nut being movably arranged in housing and a microswitch being fixedly mounted in housing from top to bottom in the housing, it is set between the push rod and T-shape lance there are one cam, the beneficial effects of the utility model are：The utility model is moved down by drying the idler wheel triggering push rod of bender, push rod pushes cam rotation, and cam pushes lance to move down, so as to which adjusting nut be pushed to move down, adjusting nut is by pushing the contact on microswitch, it is formed and is powered, when idler wheel leaves push rod, the first spring and second spring drive push rod to move on the net, resetting spring drives lance and adjusting nut to move on the net, lance up moves that cam is pushed to rotate, and forms power-off, which stablizes.
Description
Technical field
The utility model is related to travel switch field, specially a kind of travel switch.
Background technology
Travel switch, one kind of position switch (also known as limit switch), is a kind of common low current master control electrical apparatus.It utilizes
The collision of manufacturing machine moving component makes its contact action to realize connection or disjunction control circuit, reaches certain control mesh
's.In general, this kind of switch is used to position or the stroke of limit mechanical movement, make movable machinery automatic by certain position or stroke
Stopping, counter motion, variable motion or automatic back and forth movement etc., when baking bender carries out drying curved to spectacle lens, due to existing
Travel switch is unstable, and curved tabletting is dried when drying curved and is often contacted with drying the bowl side of bender, causes to dry curved eyeglass curvature
Not enough.
Invention content
In view of the above problems, the utility model provides a kind of travel switch.
A kind of travel switch, including housing, it is characterised in that：In the housing from top to bottom one be movably arranged on housing
Interior push rod, a T-shape lance being movably arranged in housing, an adjusting nut being movably arranged in housing and one
A microswitch being fixedly mounted in housing is set between the push rod and T-shape lance there are one cam, and the cam passes through
Rivet is movably arranged in housing, and the resetting spring being fixedly connected with transverse slat is equipped with below the transverse slat both ends of the T-shape lance,
The other end of the resetting spring is fixedly connected with the casing, the lower end of the T-shape lance open up there are one with adjusting nut
The screw hole that screw rod matches, the adjusting nut are rotatably installed in the lower section of T-shape lance, and the upper end of the microswitch is equipped with
One contact.
The lower end both sides of the push rod are equipped with the first limited block and the second limited block that setting is integrally formed with push rod, described
It is connected respectively by the first spring and second spring between first limited block and housing and the second limited block and housing, described the
One end of one spring is fixedly connected with the casing, and the other end is fixedly connected with the first limited block, one end of the second spring and shell
Body is fixedly connected, and the other end is fixedly connected with the second limited block.
Several fixing screwed holes are offered on the housing.
The beneficial effects of the utility model are：The utility model is moved down by drying the idler wheel triggering push rod of bender,
Push rod pushes cam rotation, and cam pushes lance to move down, and so as to which adjusting nut be pushed to move down, adjusting nut is by pushing away
Contact on dynamic microswitch, forms and is powered, and when idler wheel leaves push rod, the first spring and second spring drive push rod to transport on the net
Dynamic, resetting spring drives lance and adjusting nut to move on the net, and lance up moves that cam is pushed to rotate, and is formed disconnected
Electricity, the utility model stroke are stablized.
