Description

Technical Field

[0001] The utility model relates to the technical field of digital clamp meters, in particular to a digital clamp meter with a protection structure. Background Art

[0002] A digital clamp meter is an electrical instrument specifically used to measure the current in a running electrical circuit.

[0003] When in use, you only need to place the measured wire in its fork to easily read the current value. It is also equipped with background light and clamp head lighting functions, which is convenient for use in low-light environments. In addition, the digital clamp meter also has functions such as data retention and maximum / minimum value measurement, which provides great convenience for electricians. The clamp part of the digital clamp meter is usually made of relatively fragile plastic or lightweight metal to facilitate operation and reduce the overall weight. During use, if it is accidentally dropped or collides with a hard object, it is easy to cause damage to the clamp part. Therefore, the existing Chinese utility model patent disclosed by announcement number CN214310678U: a digital clamp meter with a protective shell, the application can effectively protect the clamp head through the protective shell, and avoid the clamp head directly touching the ground and causing The spring, buffer sheet and rubber layer are squeezed during the retreat process, and the elasticity and buffering of the spring, buffer sheet and rubber layer can effectively reduce the impact force. However, since the squeezing spring and buffer sheet are added to the overall structure, after being subjected to impact pressure, especially after falling to the ground, the squeezing spring and buffer sheet will produce a reverse force after shrinking and deforming, which can easily cause the instrument to rebound on the ground, thereby easily causing the instrument to be hit for the second time. In addition, in the application, the protective shell is installed on the clamp by a slider, a U-shaped plate, a connecting plate and a hand-tightening bolt. Therefore, the overall installation structure is relatively complicated, and the hand-tightening bolts are easy to loosen, resulting in unstable installation of the overall structure and inconvenient disassembly.

The first limit block 11 is movably installed in the first stud 10, and the first stud 10 is movably installed in the corresponding hard plastic baffle 8. A pull button 12 is also movably installed on one side of the first limit block 11, that is, the rubber cover 7 and the hard plastic baffle 8 are movably installed on the outside of the clamp 5 through the quick-release mechanism 9.

[0021] like Figure 2 As shown, both sides of the clamp 5 are provided with a card slot 13, and the clamps 5 located at both sides of the card slot 13 are provided with a slot 14;

[0022] like Figure 2-Figure 3 As shown, the two hard plastic baffles 8 are respectively fixedly installed with a clamping strip 15 on one side opposite to the other, and the hard plastic baffles 8 located on both sides of the clamping strip 15 are provided with screw holes 16, and the rubber cover 7 is inserted and installed on the outside of the clamp 5 through the two hard plastic baffles 8, and the clamping strip 15 is clamped in the corresponding clamping groove 13. The setting of the rubber cover 7 can provide the clamp 5 with impact protection, and the hard plastic baffle 8 and the clamping strip 15 cooperate with the clamping grooves 13 on both sides of the clamp 5 to achieve a quick installation of the rubber cover 7;

[0023] like Figure 2-Figure 4As shown, a mounting groove 17 is provided in the first stud 10, and two second limit blocks 18 are fixedly installed on the inner side of the mounting groove 17. A connecting shaft 23 is fixedly installed on one side of the first limit block 11, and a screw groove 20 is provided at the center position of one side of the connecting shaft 23. Two slide grooves 19 are provided on the outer side of the first limit block 11.

[0024] It should be noted that the utility model is a digital clamp meter with a protective structure. When installing the protective cover 6, the hard plastic baffles 8 on both sides of the rubber cover 7 can be pinched by hand, and the rubber cover 7 and the two hard plastic baffles 8 are installed on the outside of the clamp 5 through interlacing. When the hard plastic baffle 8 drives the first limit block 11 on one side to contact the clamp 5, the arc edge on the outside of the clamp 5 and the arc edge on one side of the first limit block 11 can be used, so that the first limit block 11 is restricted by the clamp 5 and moves to one side, thereby making the first limit block 11 drive the connecting shaft 23 to move in the installation groove 17 of the first stud 10, and the first limit block 11 also compresses the spring 21 into the installation groove 17. One side is compressed, so that the side of the first limit block 11 away from the connecting shaft 23 is flush with the side of the hard plastic baffle 8, so that the rubber cover 7 can be installed on the outside of the clamp 5 with the help of the two rubber covers 7, and then, the clamping strips 15 on the opposite sides of the two hard plastic baffles 8 are respectively clamped in the corresponding clamping grooves 13, and when the first limit block 11 moves to the position of the clamping groove 13, since the first limit block 11 is no longer restricted by the clamp 5, it rebounds and moves with the help of the rebound force of the compression spring 21, so that one side of the first limit block 11 is clamped into the slot 14, thereby completing the rapid installation of the entire protective cover 6, and the rubber cover 7 can be used to provide protection for the clamp 5;

[0025] When the protective cover 6 needs to be removed, the button 12 only needs to be manually pulled to one side, so that the button 12 can pull the first limit block 11 into the installation groove 17 through the second stud 22 and the connecting shaft 23, thereby making one side of the first limit block 11 disengage from the slot 14. At the same time, the two sliding grooves 19 on the outer side of the first limit block 11 move on the corresponding second limit blocks 18 respectively, and make the first limit block 11 finally located in the installation groove 17 on one side of the two second limit blocks 18. Then, the first limit block 11 is driven to rotate a certain angle through the button 12, the second stud 22 and the connecting shaft 23, so that the position of the first limit block 11 is limited by the two second limit blocks 18. Then, the remaining three first limit blocks 11 can be operated in the same way as above, and the protective cover 6 can be quickly removed without the aid of external tools.
