Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and embodiments.

As shown in fig. 1-2, the utility model provides a time sensitive switch, which comprises a mechanical timer 2, a housing 1 for installing the mechanical timer 2, and a contact column 21 connected to the mechanical timer 2 in a sliding manner along the radial direction of the mechanical timer 2; a strip hole 22 for a contact column 21 to slide is arranged in the mechanical timer 2, a semicircular first slide 6 and a semicircular second slide 8 are arranged on a shell 1 on the inner side of a knob of the mechanical timer 2, inlets of the first slide 6 and the second slide 8 are respectively positioned at two sides of the contact column 21 and are respectively provided with a first baffle 7 and a second baffle 9, the first slide 6 and the second slide 8 are fixed on the shell 1, the first baffle 7 and the second baffle 9 are respectively connected to the end part of the slide through two rotating shafts perpendicular to the mechanical timer 2 in a rotating manner, both the two rotating shafts are provided with coil springs for limiting self rotation, the rotating driving force of the mechanical timer is smaller than the elastic force of the coil springs for blocking the first baffle 7 and the second baffle 9 to rotate, a first inner ring 10 which is communicated with a power supply and is conductive is arranged in the first slide 6, the end part of the first inner ring 10, which is close to the first baffle 7, is non-conductive, a second inner ring 11 is arranged in the second slide way 8, the second inner ring 11 is not conductive, but the end part close to the second baffle 9 is conductive and is communicated with a power supply, and scales 5 are arranged on the shell 1 on the periphery of the mechanical timer 2.

According to the above technical scheme, the utility model discloses a principle does: the contact column 21 is connected to the mechanical timer 2 in a sliding manner along the radial direction through the slot 22, and rotates around the rotation axis of the mechanical timer 2 along with the rotation of the mechanical timer 2. When the timing starting is needed, the mechanical timer 2 is rotated towards the second slideway 8 (clockwise direction in the drawing) by rotating the knob until the knob indicates the corresponding timing position, the contact column 21 slides towards the second slideway 8 and contacts with the second inner ring 11, and the contact column 21 is in an insulation state in the second slideway 8 because the second inner ring 11 is not electrically conductive except the end part. When the timing is over, the contact column 21 starts to conduct electricity when the mechanical timer 2 rotates and slides to the end of the second slideway 8, and because the driving force of the mechanical timer 2 is smaller than the resistance force caused by the second baffle 7, the contact column 21 stays at the position of the second baffle 9, namely the end of the second inner ring 11 to conduct electricity continuously, and can only be reset by manually rotating the knob to stop electrifying. When timing closing is needed, the mechanical timer 2 is rotated towards the second slideway 8 (anticlockwise direction in the drawing) by rotating the knob, the contact column 21 slides to a preset position of the first slideway 6 along with the mechanical timer 2, the contact column 21 conducts electricity through the first inner ring 10 firstly, when timing is finished, the contact column 21 does not conduct electricity when sliding to the end part of the first inner ring 10, a circuit is disconnected, the contact column 21 is blocked by the first baffle 7 and stays at the non-conducting end part all the time, and timing closing is completed. When retiming is required, the resistance of the first shutter 7 and the second shutter 9 is overcome by manual force. In the process, the inner walls of the two slideways are made of elastic materials, and the widths of the two slideways can be slightly smaller than the diameter of the contact column, so that the first inner ring 10 or the second inner ring 11 can be in full contact with the contact column 21 conveniently. The contact column 21 can be installed on the metal conductive mechanical timer 2 by matching with the groove, the bar hole 22, etc., or can be directly connected on the knob of the mechanical timer 2 in a sliding way, and the conducting wire is arranged on the knob for connection.
