Description
Technical Field
[0001] This utility model relates to the field of instrument and meter repair technology, specifically a repair device for instrument and meter repair. Background Technology
[0002] A multimeter, also known as a multi-meter, is an indispensable measuring instrument in the power electronics and other related industries. Its primary purpose is to measure voltage, current, and resistance. Multimeters are classified into analog multimeters and digital multimeters based on their display method. They are multi-functional, multi-range measuring instruments. Generally, a multimeter can measure DC current, DC voltage, AC current, AC voltage, resistance, and audio levels. Some multimeters can also measure AC current, capacitance, inductance, and certain semiconductor parameters (such as beta). Most instruments require a multimeter for repair and testing.
[0003] However, existing technologies still have the following problems:
[0004] Firstly, existing instrument repair devices often fail to properly connect to instruments during repair, leading to loose connections and hindering effective repair and testing.
[0005] Secondly, most existing instrument repair devices cannot properly secure the instruments during repair, making them unstable and increasing the difficulty of repair work for maintenance personnel.
[0006] To address the aforementioned problems, the inventors propose a repair device for instrument and meter maintenance to solve these issues. Utility Model Content
[0007] To address the problems that most instrument repair devices cannot properly connect to and secure instruments during repair, the purpose of this invention is to provide a repair device for instrument repair.
[0008] To solve the above technical problems, the present invention adopts the following technical solution: a repair device for instrument repair, comprising a repair device, the upper end of which is provided with three connecting mechanisms for connecting the repair device to the device being tested. A fixing mechanism is fixedly provided on one side of the repair device for convenient fixing of the repair device. Each connecting mechanism includes a connection port, a connecting wire fixedly provided on one side of the connection port, a connecting plate fixedly provided at one end of the connecting wire, a detection plate fixedly provided on one side of the connecting plate, a connecting rod fixedly provided inside the connecting plate, a connecting clamp plate provided on the outer surface of the connecting rod, a spring fixedly provided at the lower end of the connecting clamp plate, and a detection clamp plate fixedly provided on one side of the connecting clamp plate. The upper end of the repair device has three grooves, and the inner surfaces of the three grooves slide against the outer surfaces of the three connection ports. The upper ends of the three connecting plates each have connecting slots, and the inner surfaces of the three connecting slots slide against the outer surfaces of the three connecting clamp plates. One side of each of the three connecting clamp plates has a connecting groove, and the inner surfaces of the three connecting grooves rotatably fit against the outer surfaces of the three connecting rods.
[0009] Preferably, two fixing plates are fixedly provided on one side of the maintenance equipment, and a fixing rod is fixedly provided at one end of the opposite face of the two fixing plates. A fixing band is provided on the outer surface of the fixing rod, and a fixing ring is sleeved on the outer surface of the fixing band. Two fixing clamping plates are fixedly provided on one side of the maintenance equipment, and a fixing clamping rod is fixedly provided at one end of the opposite face of the two fixing clamping plates. A fixing block is fixedly provided on the outer surface of the fixing clamping rod. A fixing groove is opened at the upper end of the fixing band, and the inner surface of the fixing groove is rotatably fitted with the outer surface of the fixing rod. Multiple fixing slots are opened on the outer surface of the fixing band, and the inner surface of one of the fixing slots is fitted with the outer surface of the fixing block. The fixing rod and the fixing clamping rod are used in conjunction.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] 1. This utility model, through a connecting mechanism, allows the connecting plate to allow the connection port of one end of the connecting wire to be inserted into the groove when the instrument needs to be repaired and tested. Then, pressing the connecting plate allows it to rotate within the connecting groove on the connecting plate, thereby rotating the detection plate. The connecting plate can also limit the movement of the connecting rod on the outer surface through the connecting groove. After that, the detection plate is attached to the position to be tested. Releasing the connecting plate allows it to be reset by the spring and connected to the position to be tested. This enables the instrument repair device to connect the instrument effectively.
[0012] 2. This utility model, through a fixing mechanism, allows the fixing band on one side of the fixing rod on the fixing plate to be pulled when the equipment needs to be fixed. This allows the fixing band to rotate on the outer surface of the fixing rod on the fixing plate through the fixing groove, thereby adjusting the length of the fixing band. Then, the fixing band is folded to the other side of the fixing rod, and the fixing groove is engaged with the fixing block. The fixing band is then limited by sliding the fixing ring on the outer surface of the fixing band, thus ensuring that the instrument repair device can be well fixed when repairing instruments.

A fixing clamping rod 36 is fixedly installed at one end of the opposite faces of the two fixing clamping plates 38. A fixing block 37 is fixedly installed on the outer surface of the fixing clamping rod 36. Through the fixing mechanism 3, under the action of the fixing block 37, when it is necessary to fix the maintenance equipment 1... Pull the fixing strap 33 on one side of the fixing rod 36 on the fixing plate 38 so that the fixing strap 33 can rotate on the outer surface of the fixing rod 31 on the fixing plate 30 through the fixing groove 32, thereby adjusting the length of the fixing strap 33. Then fold the fixing strap 33 to the other side of the fixing rod 36, and at the same time, the fixing groove 35 is engaged with the fixing block 37. By sliding the fixing ring 34 on the outer surface of the fixing strap 33, the fixing strap 33 can be limited, thereby achieving the purpose of fixing the instrument and meter repair device well when repairing the instrument and meter.
