Technical proposal

The utility model provides a tilting switch, includes protecgulum and hou gai, the protecgulum with the inside of back lid is provided with the space that triggers, the inside metal spin that is provided with in space that triggers, the downside butt of metal spin is connected with the wane, the downside of wane is connected with and is located the protecgulum with the inside simple to operate of back lid, the excellent micro-gap switch of electric conductivity.

Further, the micro-gap switch includes box body and lid, the inside of box body be provided with run through and sliding connection in the push rod of box body, the push rod with fixedly connected with spring between the inner wall of box body, the downside of spring be provided with set firmly in the inside shell fragment terminal of box body, fixedly connected with is located on the shell fragment terminal the shell fragment of spring downside, the right-hand member fixedly connected with movable contact of shell fragment, the right side of shell fragment terminal be provided with set firmly in contact terminal on the box body, contact terminal's left end fixedly connected with is located the stationary contact of movable contact downside.

Further, a distance adjusting piece fixedly arranged on the box body is arranged on the upper side of the movable contact.

Further, the left end of the rocker is hinged to the box body, and the middle of the rocker is abutted to the push rod.

Further, the spring terminal is connected with the spring through a rivet.

Further, the micro switch is fixed with the front cover and the rear cover through screws.

Advantageous effects

Compared with the prior art, the utility model has the following beneficial effects: when the metal rolling ball is normally placed, the rocker is extruded by the gravity of the metal rolling ball, so that the push rod is pressed and controls the fixed contact to be in contact with the movable contact, and when the inclination angle is larger than 45 degrees and even the metal rolling ball is inclined, the vertical component force of the gravity of the metal rolling ball is insufficient to overcome the elasticity of the spring, the spring further enables the push rod to move upwards, the elastic sheet is tilted upwards and enables the movable contact to be separated from the fixed contact, and the effect of automatic power failure during inclined inclination is achieved; the shell fragment becomes integratively with shell fragment terminal adoption riveting mode, can increase the conductivility between the two, and overall resistance is low, and it is few to generate heat, reduces unnecessary energy consumption, need not to install two in two steps when the installation, has also saved the adjustment step of flavouring of two when the installation after linking as an organic whole, and overall installation is more convenient, improves production efficiency.

Detailed Description

For a better illustration of the present utility model, the following description is made with reference to the accompanying drawings and examples:

as shown in fig. 1-4, the utility model discloses a dumping switch, which comprises a front cover 1 and a rear cover 2, wherein a triggering space 4 is arranged in the front cover 1 and the rear cover 2, a metal rolling ball 5 is arranged in the triggering space 4, a rocker 16 is connected with the lower side of the metal rolling ball 5 in an abutting manner, and a micro switch which is positioned in the front cover 1 and the rear cover 2 and is convenient to install and excellent in electric conductivity is connected with the lower side of the rocker 16.

Further, the micro-gap switch includes box body 7 and lid 6, the inside of box body 7 be provided with run through and sliding connection in push rod 13 of box body 7, push rod 13 with fixedly connected with spring 14 between the inner wall of box body 7, the downside of spring 14 is provided with fixedly set up in the inside shell fragment terminal 9 of box body 7, fixedly connected with is located shell fragment 15 of spring 14 downside on shell fragment terminal 9, the right-hand member fixedly connected with movable contact 11 of shell fragment 15, the right side of shell fragment terminal 9 is provided with fixedly set up in contact terminal 8 on the box body 7, contact terminal 8's left end fixedly connected with is located the stationary contact 10 of movable contact 11 downside.

Further, a distance adjusting piece 12 fixedly arranged on the box body 7 is arranged on the upper side of the movable contact 11.

Further, the left end of the rocker 16 is hinged to the box body 7, and the middle of the rocker 16 abuts against the push rod 13.

Further, the spring terminal 9 is connected with the spring 15 by a rivet.

Further, the micro switch is fixed with the front cover 1 and the rear cover 2 through screws 3.
