Detailed Description
The invention is further described in connection with the following detailed description, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the invention easy to understand.
As shown in figures 1 and 2, a switch test plug comprises a cylinder 1, a handle I2, a handle II 3, a transmission rod I4, a transmission rod II 5, a wiring terminal 6, a shaft sleeve 7 and a ratchet wheel 8, wherein the cylinder 1 is of a hollow cylinder shape with half overlapped, a plurality of wiring terminals 6 are fixedly connected to the outer wall of the cylinder 1, the outer layer of the overlapped part in the cylinder 1 is fixedly connected with the transmission rod I4 and the inner layer of the transmission rod I4 is fixedly connected with the transmission rod II 5, the other end of the transmission rod I4 is fixedly connected with the shaft sleeve 7, a shaft body 9 is arranged in the shaft sleeve 7, the lower end of the shaft body 9 is connected with the transmission rod II 5 through a shaft pin 10, a bidirectional ratchet wheel 8 corresponding to the shaft body 9 is arranged at the upper end of the shaft sleeve 7, the handle II 3 is fixedly connected to the outer wall of the ratchet wheel 8, a dial 11 is arranged at the top of the ratchet wheel 8, and the upper end of the shaft body 9 is fixedly connected with the handle I2.
It is noted that, the corresponding dial on the shaft body 9 in the ratchet wheel 8 is provided with a pointer, so that the pointer 12 points to the scale corresponding to the inner diameter of the switch plug, and then the test work of the circuit breaker can be performed.
In this embodiment, the binding post 6 is provided with a butterfly bolt 13 for fixedly connecting the line to be measured to the binding post 6, so as to prevent a large measurement error caused by poor line contact.
In this embodiment, the cylinder 1 is rolled from a beryllium copper plate, which is not easy to conduct heat and electricity, and the rolled cylinder is elastic and is not easy to deform and destroy.
In addition, a ratchet handle 14 is fixedly connected to one side of the ratchet 8 for adjusting the direction of the ratchet 8.
Based on the above, the diameter of the cylinder 1 can be adjusted at will, one plug is suitable for trolley type breaker plugs with different capacities, when the trolley type breaker plug is used, the contact between a contact and a test wire clamp is closer to the working state of the breaker, experimental data are more real and accurate, when the trolley type breaker plug is used, a test wire is connected to the wiring terminal 6, a tube of the plug is adjusted to be smaller than the inner diameter of the tested breaker plug through the ratchet handle 14, the test plug is inserted into a switch plug, after the direction of the ratchet handle 14 is adjusted, the handle I2 and the handle II 3 are respectively moved by two hands, so that the test work of the breaker can be carried out after the pointer 12 points to scales corresponding to the inner diameter of the switch plug, after the test is finished, the ratchet handle 14 is adjusted by the opposite direction, and then the handle I2 and the handle II 3 are moved in the opposite direction, so that the tube of the test plug is smaller than the inner diameter of the breaker plug, and the plug is taken out.
It will be appreciated by those skilled in the art that the present invention can be carried out in other embodiments without departing from the spirit or essential characteristics thereof. Accordingly, the above disclosed embodiments are illustrative in all respects, and not exclusive. All changes that come within the scope of the invention or equivalents thereto are intended to be embraced therein.
