A dustproof shielding plate is fixedly connected at the middle position between the two lifting slide strips. A sliding block is fixedly connected to the middle of the top of one side of the dustproof shielding plate.

[0010] Preferably, the external mounting box is provided with a side circulation cooling mechanism;

[0011] The side-circulating cooling mechanism includes a mounting side box, a protective inner mesh, a mounting inner block, a cooling fan, a protective narrow mesh, and a dustproof bottom mesh;

[0012] The external mounting box has mounting side boxes embedded in the top of both sides. A protective inner net is embedded in the middle of one side of each mounting side box. An inner mounting block is embedded in the middle of the inner side of each mounting side box. Cooling fans are embedded in the middle of both ends of each inner mounting block. The cooling fans are powered by an external power source. A protective narrow net is embedded in the bottom of the protective inner net.

[0018] Compared with the prior art, the advantages of this utility model are: the structure of this utility model is scientific and reasonable, and it is safe and convenient to use.

[0019] 1. A front-end lifting rapid observation mechanism is set up. The lifting slide and its components are installed on the front of the sealed box door by the installation guide bar. The top of the installation guide bar is limited by the limit bar, and the bottom of the lifting slide bar is supported by the support spring. By moving the slider, the dustproof shield can slide along the inside of the installation guide bar, so that the tester can quickly observe the values ​​on the main body of the tester. When it is not necessary to observe the inside of the external installation box, the dustproof shield can cover the side window of the sealed box door, effectively preventing the sealed box door from being affected by external contamination during normal use, and further improving the overall convenience of the low-voltage tester.

[0020] 2. A side-circulating cooling mechanism is installed. A cooling fan inside the mounting block generates a continuous airflow inside the mounting side box. A narrow protective mesh protects the air vents at the bottom of the mounting side box to prevent external dust from entering the external mounting box. The continuous airflow is guided into the external mounting box through the inner protective mesh. The continuous airflow guides the heat generated inside the detector body downwards, and the hot air from inside the external mounting box is exhausted downwards through the dustproof bottom mesh. This achieves heat dissipation inside the external mounting box, ensuring that the low-voltage detector can remain within a suitable temperature range even after long-term use, indirectly improving the overall service life of the low-voltage detector.

[0021] 3. A bottom lifting support mechanism is set up. The long strip slides down through the guide narrow groove, thereby separating the support rubber wheel from the limiting rubber strip. The position of the support rubber wheel is fixed by the limiting bolt. The external mounting box is moved quickly by the rolling of the support rubber wheel. By tightly fitting the outside of the support rubber wheel with the outside of the limiting rubber strip, the support rubber wheel cannot rotate. The support rubber wheel supports the bottom of the external mounting box, which further improves the ease of use of moving and placing the low-voltage tester. Attached Figure Description

[0032] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0033] Example: Figure 1-4 As shown, this utility model provides a technical solution, a low-voltage detector, including an external mounting box 1, a detector body 2 fixedly mounted in the middle of the inner side of the external mounting box 1, and a sealed box door 3 hinged to the front of the external mounting box 1.

[0034] The sealed box door 3 is equipped with a front-end lifting rapid observation mechanism 4 on its side;

[0035] The front-end lifting rapid observation mechanism 4 includes a mounting guide bar 401, a limiting top bar 402, a lifting slide bar 403, a support spring 404, a dustproof shielding plate 405, and a sliding block 406;

[0036] Both sides of the sealed door 3 are fixedly connected to mounting guides 401. A limit strip 402 is fixedly installed at the top of the mounting guide 401. A lifting slide 403 is slidably engaged inside the mounting guide 401. A support spring 404 is embedded in the middle of the inner side of the lifting slide 403. A dustproof shielding plate 405 is fixedly connected at the middle position between the two lifting slides 403. A sliding block 406 is fixedly connected to the top center of one side of the dustproof shielding plate 405. A transparent window is provided at the top front of the sealed door 3. The outer side of the lifting slide 403 slides tightly against the inner wall of the mounting guide 401, and the side of the dustproof shielding plate 405 slides tightly against the side of the sealed door 3. The lifting slide is adjusted by the mounting guides 401. The slide bar 403 and its components are installed on the front of the sealed box door 3. The top of the mounting guide bar 401 is limited by the limiting top bar 402, and the bottom of the lifting slide bar 403 is supported by the support spring 404. By moving the slider 406, the dustproof shielding plate 405 can be moved along the inner side of the mounting guide bar 401, so that the tester can quickly observe the values ​​on the main body 2 of the tester. When it is not necessary to observe the inside of the external mounting box 1, the dustproof shielding plate 405 can cover the side window of the sealed box door 3, effectively preventing the sealed box door 3 from being affected by external pollution during normal use, and further improving the overall ease of use of the weak current tester.

[0037] The external mounting box 1 is equipped with a side circulation cooling mechanism 5 on its side;

[0038] The side circulation cooling mechanism 5 includes a mounting side box 501, a protective inner mesh 502, a mounting inner block 503, a cooling fan 504, a protective narrow mesh 505, and a dustproof bottom mesh 506;

[0039] The external mounting box 1 has mounting side boxes 501 embedded in the top of both sides. A protective inner mesh 502 is embedded in the middle of one side of each mounting side box 501. An inner mounting block 503 is embedded in the middle of the inner side of each mounting side box 501. Cooling fans 504 are embedded in the middle of both ends of the inner mounting block 503. The cooling fans 504 are powered by an external power source. A protective narrow mesh 505 is embedded in the bottom of the protective inner mesh 502. A dustproof bottom mesh 506 is embedded in the middle of the bottom surface of the external mounting box 1. The sides of the protective inner mesh 502 are tightly slidably fitted against the inner wall of the external mounting box 1, and the bottom surface of the dustproof bottom mesh 506 is tightly slidably fitted against the outer bottom surface of the external mounting box 1. The cooling fan 504 inside the inner block 503 generates a continuous airflow inside the mounting side box 501. The bottom air vent of the mounting side box 501 is protected by a protective narrow mesh 505 to prevent external dust from entering the outer mounting box 1. The continuous airflow is guided into the outer mounting box 1 through the protective inner mesh 502. The heat generated inside the detector body 2 is guided downwards by the continuous airflow. The hot airflow inside the outer mounting box 1 is discharged downwards through the dustproof bottom mesh 506, thereby achieving heat dissipation inside the outer mounting box 1. This ensures that the low-voltage detector can still maintain a suitable temperature range after long-term use, indirectly improving the overall service life of the low-voltage detector.

[0040] The bottom of the external mounting box 1 is equipped with a bottom lifting support mechanism 6;

[0041] The bottom lifting support mechanism 6 includes a mounting rectangular box 601, a guide narrow groove 602, a mounting strip 603, a limiting bolt 604, a support rubber wheel 605, and a limiting rubber strip 606;

[0042] An external mounting box 1 has rectangular mounting boxes 601 embedded on both sides of its bottom surface. Each rectangular mounting box 601 has a guide groove 602 extending through its center at both ends. An mounting strip 603 is slidably engaged with the center of the inner side of the rectangular mounting box 601. A limit bolt 604 is threadedly installed at the end of the mounting strip 603. Support rollers 605 are fixedly installed at both ends of the bottom surface of the mounting strip 603. Limit strips 606 are adhered to the sides of the rectangular mounting box 601 corresponding to the support rollers 605. The ends of the mounting strip 603 are tightly slidably fitted against the inner wall of the rectangular mounting box 601, and the sides of the limit bolts 604 are also tightly slidably fitted against the ends of the rectangular mounting box 601. The bottom arc surface of the 6th ring is tightly fitted with the outer side of the supporting rubber wheel 605, and the outer side of the limiting rubber strip 606 is provided with anti-slip texture. The long strip 603 is installed by sliding down through the guide narrow groove 602, thereby separating the supporting rubber wheel 605 from the limiting rubber strip 606. The position of the supporting rubber wheel 605 is fixed by the limiting bolt 604. The rolling of the supporting rubber wheel 605 allows the external mounting box 1 to move quickly. By tightly fitting the outer side of the supporting rubber wheel 605 with the outer side of the limiting rubber strip 606, the supporting rubber wheel 605 cannot rotate. The supporting rubber wheel 605 supports the bottom of the external mounting box 1, further improving the ease of use of moving and placing the weak current detector.

[0043] The working principle and usage process of this utility model: In the actual application process, when using the weak current detector, the detector body 2 needs to be connected to the corresponding cable first. Then, the outside of the detector body 2 is protected by the external installation box 1 and the sealed box door 3 so that the cable can be detected in real time through the detector body 2.

[0044] When it is necessary to observe the values ​​on the main body 2 of the detector, the lifting slide bar 403 and its components are installed on the front of the sealed box door 3 by installing the guide bar 401. Then, the top of the installation guide bar 401 is limited by the limiting top bar 402, and the bottom of the lifting slide bar 403 is supported by the support spring 404. When it is necessary to observe the inside of the external installation box 1 through the side window of the sealed box door 3, the dustproof shielding plate 405 can be moved along the inside of the installation guide bar 401 by moving the slider 406, so that the tester can quickly observe the values ​​on the main body 2 of the detector.

[0045] When it is not necessary to observe the inside of the externally installed box 1, the side window of the sealed box door 3 can be covered by the dustproof shielding plate 405, which effectively prevents the sealed box door 3 from being affected by external pollution during normal use and further improves the overall ease of use of the weak current tester.

[0046] When continuous heat dissipation is required inside the external mounting box 1, the components are installed on the side of the external mounting box 1 through the mounting side box 501. Then, the cooling fan 504 inside the mounting inner block 503 generates a continuous airflow inside the mounting side box 501. The bottom air vent of the mounting side box 501 is protected by the protective narrow mesh 505 to prevent external dust from entering the external mounting box 1. The continuous airflow is introduced into the external mounting box 1 through the protective inner mesh 502.

[0047] Then, the heat generated inside the main body 2 of the detector is guided downward by continuous airflow, and the hot airflow inside the external mounting box 1 is discharged downward by the dustproof bottom mesh 506, thereby achieving heat dissipation inside the external mounting box 1. This ensures that the weak current detector can still be maintained within a suitable temperature range after long-term use, indirectly improving the overall service life of the weak current detector.

[0048] When the low-voltage detector needs to be moved and supported, the components are installed at the bottom of the external mounting box 1 by installing the rectangular box 601. When the external mounting box 1 needs to be moved, the long strip 603 is slid down by the guide narrow groove 602, thereby separating the support rubber wheel 605 from the limiting rubber strip 606. After the support rubber wheel 605 slides to the appropriate position, the position of the support rubber wheel 605 is fixed by the limiting bolt 604. Then, the external mounting box 1 is moved quickly by the rolling of the support rubber wheel 605.

[0049] When it is necessary to support and fix the bottom of the external mounting box 1, the outer side of the support rubber wheel 605 and the outer side of the limiting rubber strip 606 are tightly fitted so that the support rubber wheel 605 cannot rotate. In this way, the support rubber wheel 605 supports the bottom of the external mounting box 1, which further improves the ease of use of moving and placing the weak current detector.

[0050] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
