Description

Technical Field

[0001] This utility model relates to the field of measuring instrument technology, specifically a multi-channel power measuring instrument with wiring protection function. Background Technology

[0002] Multi-channel power meters measure the power of different electrical devices and dynamically measure and analyze the changes in power consumption of electrical appliances during use. When multiple electrical devices work together, it is necessary to achieve simultaneous measurement and analysis of multiple channels. After the connection between the measuring instrument's socket and the plug, the end of the connecting wire is prone to loosening due to external factors, resulting in poor signal contact.

[0003] However, in actual use, after the multi-channel power meter's connector and the cable are connected, the end of the cable is easily damaged due to external factors, resulting in poor signal contact. In view of this, we propose a multi-channel power meter with wiring protection function. Utility Model Content

[0004] The purpose of this invention is to provide a multi-channel power measuring instrument with wiring protection function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-channel power measuring instrument with wiring protection function, comprising an instrument body, a socket being provided on the surface of the instrument body, a protection mechanism being provided on the outer side of the instrument body, and a promoting mechanism being provided on the outer side of the instrument body, the protection mechanism comprising:

[0006] The movable groove is located on the outside of the instrument body. A straight rod is movably connected to the inner wall of the movable groove. A torsion spring is fixedly installed on the arc surface of the straight rod. A support arm is fixedly connected to the end of the straight rod away from the inner wall of the movable groove. A support frame is fixedly installed on the surface of the support arm.

[0007] A clamping ring is fixedly installed on the lower surface of the support frame. A return spring is fixedly connected to the inner wall of the clamping ring. A sliding block is fixedly connected to the end of the return spring away from the inner wall of the clamping ring. A clamping ring is fixedly installed on the surface of the sliding block.

[0008] Preferably, the promoting mechanism includes a retarder groove, which is formed on the side wall of the instrument body. The surface of the support arm has a movable hole, and a telescopic spring is fixedly connected to the inner wall of the movable hole. A retarder ball is fixedly connected to the end of the telescopic spring away from the movable hole.

[0009] Preferably, the diameter of the retardant ball is adapted to the diameter of the movable hole, and the inner wall of the retardant groove is provided with a limiting hole, the shape of which is adapted to the shape of the retardant ball.

[0010] Preferably, the diameter of the movable groove is adapted to the diameter of the straight rod, so that the straight rod can move inside the movable groove.

[0011] Preferably, the inner ring surface of the clamping ring is provided with a sliding groove, and the shape of the sliding groove is adapted to the shape of the sliding block.

[0012] Preferably, the surface of the clamping ring is provided with protrusions, and the shape of the clamping ring is larger than the shape of the sliding groove.

[0013] Compared with the prior art, this utility model provides a multi-channel power measuring instrument with wiring protection function, which has the following beneficial effects:

[0014] 1. This multi-channel power measuring instrument with wiring protection function has a protection mechanism. When the plug of the appliance is inserted into the socket, the connecting wire is clamped into the inside of the clamping ring. The clamping ring on the support frame rotates inside the movable groove under the action of the torsion spring and the straight rod, so that the support frame can move and the plug can be inserted into the socket. At the same time, the clamping ring inside the clamping ring clamps the wiring and prevents the wiring from being dragged. The clamping ring drives the sliding block and the return spring to move inside the sliding groove, protecting the connection between the plug and the connecting wire and facilitating the instrument to measure.

[0015] 2. This multi-channel power measuring instrument with wiring protection function has a facilitating mechanism. The slow ball on the support frame moves along the slow groove under the action of the telescopic spring. The limiting hole on the slow groove limits the movement of the support frame, slows down the movement speed of the support frame, and prevents the support frame from being dragged by the wiring due to external factors. This further protects the connection of the plug and the connecting wire and promotes the accuracy of the measuring instrument's measurement data. Attached Figure Description
