Device for copper generation principle experimental instrument

Abstract

The invention discloses a device for a copper generation principle experimental instrument. The device comprises a knocking rod and a bottom plate, a trapezoidal table is arranged on the top surface of the bottom plate, a soft leather hose is uniformly wound on the trapezoidal table, a pair of sliding rods is arranged on the left side of the trapezoidal table, a transverse plate is arranged between the top ends of the two sliding rods, and the two ends of the bottom surface of the transverse plate are fixedly connected with the top ends of the two sliding rods respectively. A sliding assembly is arranged between the two sliding rods, a vertical plate is arranged on the right side of the trapezoidal table, the bottom surface of the vertical plate is fixedly connected with the top surface of the bottom plate, a sliding groove is formed in the top surface of the vertical plate, a threaded rod is arranged in the sliding groove, and the threaded rod is rotatably connected with the inner bottom surface and a top surface port of the sliding groove through bearings. An adjusting handle is fixedly arranged at the top end of the threaded rod, a sliding block is slidably arranged in the sliding groove, a threaded groove is formed in the middle of the sliding block, the threaded rod is located in the threaded groove and is in threaded connection with the threaded groove, and a pair of symmetrical clamping assemblies is arranged on the side surface of the vertical plate. The device is easy to operate and convenient to adjust.

Description

technical field [0001] The invention relates to the technical field of experiments on the principle of copper formation, in particular to a device for an experimental instrument on the principle of copper formation. Background technique [0002] Commonly known as Jinniu or Tongniu, the Tongbu is made of copper and lies prone on the ground. It is about 2.3 meters long and 1.5 meters high. In the "Kunming County Chronicles" compiled by Dai Junfan during the Daoguang period of the Qing Dynasty, it was described: Tongyan held his head up to the river, and raised his feet in the shape of wanting to fight. In order to suppress the floods of the Panlong River, during the Jiaqing period of the Qing Dynasty, people cast a copper box on the bank of the Panlong River, which looks like a cow but is not a cow, and has a single horn on the top to suppress floods and warn of floods. There is a well under the base of the Tonggan, and the wall of the well runs through the Panlong River. Whe...

Problems solved by technology

[0003] There are the following problems in the devices used in the market for the principle of copper formation: 1. Because the experiment needs to use the test tube, it is generally held manually through the experiment, which is not only inconvenient to carry out the experiment operation, but also has poor stability; 2. The existing overall experiment The operation of the device is cumbersome, the cost is high, and the experimental efficiency is low
