Sand clock timing circuit open-close apparatus

Abstract

The invention provides a sand clock timing circuit open-close apparatus comprising a transparent housing, a pedestal, an intermediate channel and an electricity connection seat. The transparent housing is filled with metal fine sands; a metal block is arranged in the middle of the pedestal; the periphery of the pedestal is covered with a metal layer; the metal layer is connected with the intermediate channel via an intermediate line; the pedestal is arranged over the electricity connection seat; the electricity connection seat comprises an intermediate connection block made from metal material and an annular connection block also manufactured by metal material; the intermediate connection block is placed in the middle over the electricity connection seat; the size of annular connection block is matched with the metal layer; the intermediate connection block has close contact with the metal block; and the annular connection block has close contact with the metal layer. The sand clock timing circuit open-close apparatus can work as a sand clock and can also enable the time to be directly seen via the sand clock structure; and the open-close line can be timed.

Description

Technical field [0001] The invention belongs to the technical field of timing electrical equipment, and in particular relates to an opening and closing device for an hourglass timing circuit. Background technique [0002] An hourglass, also called a sand clock, is a device for measuring time. The hourglass consists of two transparent chambers and a narrow connecting pipe. The two transparent chambers are filled with fine sand, and the time required for the fine sand to flow from the upper transparent chamber through the narrow pipe into the bottom chamber is one cycle. Every time when the fine sand is all in the bottom cavity, the single fine sand will go through the same cycle every time the single fine sand is completely dropped. So the hourglass is often used to measure time. With the development of science and technology, there are more and more time judging tools. The traditional hourglass structure itself is difficult to connect with electronic devices. The timing f...
