Suspensible portable ammeter

Abstract

The invention discloses a suspensible portable ammeter, and belongs to the technical field of measuring instruments.The surface of an ammeter body is sleeved with an anti-collision sleeve, a mounting groove is formed in the anti-collision sleeve, the inner wall of the mounting groove makes contact with and extrudes the surface of the ammeter body, one end of the anti-collision sleeve is provided with an anti-falling sleeve, and one end of the anti-falling sleeve is provided with a sleeve hole communicated with the mounting groove; a plug is sleeved in the sleeve hole, one end of the plug is inserted into the jack of the ammeter body, the other end of the plug is fixedly connected with a lead, and the other end of the lead is fixedly connected with a measuring pen. According to the suspensible portable ammeter, the anti-collision sleeve is provided with a hanging ring and a clamping plate,so that user can conveniently hang and carry the ammeter; The anti-collision sleeve is convenient to assemble and disassemble, the anti-falling and anti-collision performance of the ammeter can be improved, the clamping block and the connecting column arranged on the anti-collision sleeve not only facilitate fixing of the measuring pen, but also can wind the wire, and the use convenience of the ammeter is improved.

Description

technical field [0001] The invention relates to the technical field of measuring instruments, in particular to a hangable portable ammeter. Background technique [0002] The ammeter is made according to the action of the current-carrying conductor in the magnetic field. There is a permanent magnet inside the ammeter, which generates a magnetic field between the poles. There is a coil in the magnetic field. There is a hairspring at each end of the coil, and each spring is connected to the ammeter. A binding post is connected by a rotating shaft between the spring and the coil, and there is a pointer at the front end of the rotating shaft relative to the ammeter. [0003] At present, ammeters are often used in the inspection and measurement of circuits, but most of the existing ammeters are not easy to hang, and they can only be carried by hand when carrying, which brings certain inconvenience to the carrying of the ammeter, and the existing ammeter is in the process of carryi...

Problems solved by technology

[0003] At present, ammeters are often used in the inspection and measurement of circuits, but most of the existing ammeters are not easy to hang, and they can only be carried by hand when carrying, which brings certain inconvenience to the carrying of the ammeter, and the existing ammeter is in the process of carrying. Because the wire set by the measuring pen is too long, it is easy to hang on the object during the moving process, causing the wire to break, and then the measuring pen cannot be used normally, which may bring some inconvenience to the user. For this reason, we have designed a A portable ammeter can be hung to solve the above problems
