Description

Technical Field

[0001] This utility model relates to the field of analyzer technology, specifically to a power quality analyzer with a protective structure. Background Technology

[0002] A power quality analyzer is a specialized portable product used for detecting and analyzing the quality of power grid operation. It can provide harmonic analysis and power quality analysis during power operation, and can perform long-term data acquisition and monitoring of power grid operation.

[0003] According to a public notice of a multi-functional quality analyzer with a protective structure (publication number: CN213986662U), in the above application, when the protective plate moves upward to a certain position on the front of the multi-functional analyzer body, the protective plate no longer protects the screen on the front of the multi-functional analyzer body, and thus the device can be used.

[0004] However, in actual use, when the power quality analyzer is used outdoors, some areas have high humidity levels, which can easily cause moisture to get into the interface of the power quality analyzer, thus affecting the use of the instrument. In view of this, we propose a power quality analyzer with a protective structure. Utility Model Content

[0005] The purpose of this invention is to provide a power quality analyzer with a protective structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a power quality analyzer with a protective structure, comprising an instrument body, a connecting pipe fixedly installed on the outer wall of the instrument body, a protective mechanism provided on the outer side of the instrument body, and a promoting mechanism provided on the outer side of the instrument body, the protective mechanism comprising: A threaded groove is formed on the arc surface of the connecting pipe, and a protective tube is threadedly connected to the surface of the connecting pipe. A groove is formed at the opening of the protective tube. A rubber ring is fixedly installed on the inner wall of a groove. An air bladder is fixedly installed on the outer arc surface of the rubber ring, and rubber protrusions are provided on the inner arc surface of the rubber ring.

[0007] Preferably, the promoting mechanism includes an auxiliary tube, which is fixedly installed on the side wall of the protective tube, and a rubber strip is fixedly installed on the arc surface of the auxiliary tube.

[0008] Preferably, the number of rubber strips is set to several, and the several rubber strips are uniformly arrayed and fixedly installed on the arc surface of the auxiliary tube.

[0009] Preferably, the auxiliary tube is fixedly installed on the side of the protective tube away from the rubber ring, so that the auxiliary tube and the protective tube can move simultaneously.

[0010] Preferably, the surface of the rubber ring is provided with an installation groove, the shape of which is adapted to the shape of the filling airbag, so that the filling airbag can be installed in the gap between the rubber ring and the protective tube.

[0011] Preferably, the filling airbag is fixedly installed on the inner wall of the protective tube, and the interior of the filling airbag is filled with inert gas to reduce the impact of the filling airbag on the stability of the external environment.

[0012] Preferably, the inner diameter of the rubber ring is arc-shaped, and the inner diameter of the rubber ring becomes thinner from the side closer to the filling air bladder to the other side.

[0013] Compared with the prior art, this utility model provides a power quality analyzer with a protective structure, which has the following beneficial effects: 1. This power quality analyzer with a protective structure has a protective mechanism. When the external plug is inserted into the connector, the protective tube is rotated. As the protective tube rotates, a rubber ring wraps around the connection between the plug and the connector. With the addition of an air bladder, the rubber ring fits tightly against the connection, thereby reducing moisture at the connection and ensuring the normal operation of the instrument.

[0014] 2. This power quality analyzer with a protective structure has a facilitating mechanism that moves the auxiliary tube as the protective tube rotates. The rubber strip seals the outside of the auxiliary tube, protecting the threaded groove of the connector and reducing the impact of the external environment, thus ensuring the usability of the instrument.

[0017] like Figures 1-4As shown, this utility model provides a technical solution: an energy quality analyzer with a protective structure, including an instrument body 1, a connecting pipe 2 fixedly installed on the outer wall of the instrument body 1, a protective mechanism 3 provided on the outer side of the instrument body 1, and a promoting mechanism 4 provided on the outer side of the instrument body 1. The protective mechanism 3 includes a threaded groove 301, a protective tube 302, a rubber ring 303, a groove 304, a filling airbag 305, and a rubber protrusion 306.

[0018] In one embodiment of this utility model, a threaded groove 301 is formed on the arc surface of the connecting pipe 2, and a protective tube 302 is threadedly connected to the surface of the connecting pipe 2. A groove 304 is formed at the opening of the protective tube 302, and a rubber ring 303 is fixedly installed on the inner wall of the groove 304. A filling air bag 305 is fixedly installed on the outer arc surface of the rubber ring 303, and a rubber protrusion 306 is provided on the inner arc surface of the rubber ring 303.

[0019] Additionally, the promoting mechanism 4 includes an auxiliary tube 401, which is fixedly installed on the side wall of the protective tube 302. A rubber band 402 is fixedly installed on the arc surface of the auxiliary tube 401. Several rubber bands 402 are evenly arrayed and fixedly installed on the arc surface of the auxiliary tube 401. The auxiliary tube 401 is fixedly installed on the side of the protective tube 302 away from the rubber ring 303, thereby allowing the auxiliary tube 401 and the protective tube 302 to move simultaneously.

[0020] In this embodiment of the invention, a mounting groove is formed on the surface of the rubber ring 303. The shape of the mounting groove is adapted to the shape of the filling airbag 305, allowing the filling airbag 305 to be installed at the gap between the rubber ring 303 and the protective tube 302. The filling airbag 305 is fixedly installed on the inner wall of the protective tube 302. The filling airbag 305 is filled with inert gas to reduce the impact of the filling airbag 305 on the stability of the external environment. The inner diameter of the rubber ring 303 is arc-shaped, and the inner diameter of the rubber ring 303 thins from the side closest to the filling airbag 305 to the other side. A cavity for the auxiliary tube 401 is formed on the surface of the instrument body 1 to facilitate the placement of the auxiliary tube 401.

[0021] In this invention, when in use, the external plug is inserted into the connector 2, and then the protective tube 302 is rotated so that the protective tube 302 rotates on the arc surface of the connector 2. As the protective tube 302 rotates, the rubber ring 303 wraps around the connection between the plug and the connector 2. With the addition of the filling air bag 305, the rubber ring 303 fits tightly against the connection, thereby reducing moisture at the connection and ensuring the normal use of the instrument body 1.

[0022] Furthermore, as the protective tube 302 rotates, it drives the auxiliary tube 401 to move. In conjunction with the rubber band 402, the auxiliary tube 401 is sealed on the outside, which protects the threaded groove 301 of the connecting tube 2, reduces the influence of the external environment, and ensures the use of the instrument body 1.

[0023] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
