The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0025] This utility model embodiment provides a handheld power quality analyzer, such as Figure 1-7 As shown, the handheld power quality analyzer includes: a power quality analyzer body 1 and a protective cover 2 covering the power quality analyzer body 1 for protecting the power quality analyzer body 1; a buffer sponge 3 disposed inside the protective cover 2 for absorbing impact energy and protecting the power quality analyzer body 1; and a storage box 4 disposed at the bottom of the protective cover 2 for storing accessories of the power quality analyzer body 1 (such as current clamps, voltage test leads, etc.).
[0026] In this embodiment, a cushioning sponge 3 is installed inside the protective cover 2. When the power quality analyzer body 1 is accidentally dropped and collides, the cushioning sponge 3 absorbs the impact energy and reduces the damage to the power quality analyzer body 1. At the same time, a storage box 4 is provided at the bottom of the protective cover 2, which can be used to store accessories of the power quality analyzer body 1, such as current clamps and voltage test leads. Through the combined design of the protective cover 2 and the cushioning sponge 3, the problem of existing handheld power quality analyzers lacking protective functions and impact-resistant design is effectively solved, avoiding damage to the equipment due to collisions, ensuring the accuracy of subsequent use, and reducing the risk of equipment scrapping. The design of the storage box 4 makes it convenient for users to store equipment accessories, prevent accessories from being lost, bring convenience to users, and reduce losses caused by lost accessories.
[0027] In a further preferred embodiment of the present invention, a connecting rod 5 is fixedly installed on the top of the protective cover 2, the connecting rod 5 is inserted into the positioning groove of the storage box 4, and the storage box 4 is provided with a positioning block 6 for limiting the connecting rod 5.
[0028] In this embodiment, when the protective cover 2 and the storage box 4 are assembled, the connecting rod 5 is inserted into the positioning groove, and the positioning block 6 limits the connecting rod 5, so that a stable connection structure is formed between the protective cover 2 and the storage box 4. Through the cooperation of the connecting rod 5, the positioning groove and the positioning block 6, the connection strength between the protective cover 2 and the storage box 4 is strengthened, making the entire protective structure more stable. When the equipment is subjected to collision or vibration, the protective cover 2 and the storage box 4 are not easy to separate, which can better protect the main body 1 of the power quality analyzer and its accessories. This connection method is simple and reliable, and it is convenient for users to install and disassemble the protective cover 2 and the storage box 4, and it is convenient for users to maintain, repair or replace parts of the equipment according to actual needs.
[0029] In a further preferred embodiment of this utility model, a cover plate 7 is hinged to one side of the storage box 4, a locking rod 8 is rotatably installed on the cover plate 7, an arc-shaped limiting piece is fixedly installed on the locking rod 8, and a U-shaped block 9 is fixedly installed on the top of the inner wall of the storage box 4, the U-shaped block 9 being engaged with the arc-shaped limiting piece.
[0030] In this embodiment, when the storage box 4 needs to be closed, the cover plate 7 is closed, and then the locking lever 8 is rotated to engage the arc-shaped limiting piece with the U-shaped block 9, thereby fixing the cover plate 7 to the storage box 4 and preventing the accessories inside the storage box 4 from falling out. When it is necessary to remove the accessories from the storage box 4, the locking lever 8 is rotated first to make the arc-shaped limiting piece rotate away from the U-shaped block 9, releasing the fixation of the cover plate 7. Then the cover plate 7 can be opened and the accessories can be taken out. Through the locking design of the arc-shaped limiting piece on the locking lever 8 and the U-shaped block 9, the cover plate 7 can be effectively fixed to the storage box 4, preventing the accessories inside the storage box 4 from falling out due to shaking or collision during carrying or use, thus ensuring the safety of the accessories. When it is necessary to remove the accessories, simply rotate the locking lever 8 to make the arc-shaped limiting piece move away from the U-shaped block 9, and the cover plate 7 can be easily opened. The operation is simple and convenient, improving the user's efficiency.
[0031] In a further preferred embodiment of this utility model, the protective cover 2 consists of two protective covers and two mounting mechanisms. The two protective covers are positioned on the upper and lower sides of the power quality analyzer body 1. The mounting mechanism consists of a connecting plate 10, a connecting plate 11, a slot 12, and an elastic steel plate 13. The connecting plate 10 and the connecting plate 11 are respectively mounted on the two protective covers, and the connecting plate 11 is inserted into the slot of the connecting plate 10. The slot 12 is opened on one side of the slot, and the elastic steel plate 13 is mounted on one side of the connecting plate 11. The elastic steel plate 13 is inclined and inserted into the slot 12.
[0032] In this embodiment, the connecting plate 11 is inserted into the slot of the connecting plate 10. At this time, the inclined elastic steel plate 13 deforms due to compression. When the elastic steel plate 13 moves to the position of the slot 12, it recovers its deformation and is locked into the slot 12, thereby limiting the connecting plate 11 and completing the installation of the protective cover 2. When it is necessary to disassemble the protective cover 2, a certain force is applied to the elastic steel plate 13 to make the elastic steel plate 13 deform again and disengage from the slot 12, so that the connecting plate 11 can be pulled out from the connecting plate 10 and the protective cover 2 can be disassembled. Through the snap-fit design between the elastic steel plate 13 and the slot 12, the quick installation and disassembly of the protective cover 2 are realized. Users can install and remove the protective cover 2 with simple operations without using complicated tools, which facilitates the maintenance, repair or replacement of parts of the power quality analyzer body 1. After the elastic steel plate 13 is inserted into the slot 12, it can effectively limit the connecting plate 11, so that the two protective covers are tightly covered on the upper and lower sides of the power quality analyzer body 1, providing reliable protection for the power quality analyzer body 1. At the same time, this snap-fit structure has a certain strength and stability, and can withstand a certain external impact, ensuring that the protective cover 2 will not easily fall off during use.
[0033] In a further preferred embodiment of this utility model, a connecting groove 14 is provided on the storage box 4, a baffle is fixedly installed in the connecting groove 14, a pull rod 15 is slidably provided on the baffle, one end of the pull rod 15 is fixedly connected to the positioning block 6, and a spring 16 is sleeved on the pull rod 15, and the two ends of the spring 16 are fixedly connected to the baffle and the baffle plate of the positioning block 6 respectively.
[0034] In this embodiment, when the storage box 4 needs to be installed, the user pulls the lever 15. The lever 15 moves the positioning block 6 to one side, away from the connecting rod 5. At the same time, the spring 16 is compressed, allowing the storage box 4 to be installed in the appropriate position, so that the connecting rod 5 is inserted into the positioning groove. Finally, the lever 15 is released, and under the elastic force of the spring 16, the positioning block 6 returns to its original position, limiting the connection rod 5, thus completing the installation of the storage box 4. When the storage box 4 needs to be disassembled, the lever 15 is pulled again, moving the positioning block 6 away from the connecting rod 5, allowing the storage box 4 to be removed. By setting up the cooperative structure of the lever 15, spring 16, and positioning block 6, the user can easily install and disassemble the storage box 4 by simply pulling and releasing the lever 15, without complicated operations or tools, greatly improving the convenience of use.
[0035] In a further preferred embodiment of the present invention, a connecting channel is provided on one side of the connecting groove 14. The connecting channel is T-shaped and extends out of the storage box 4. A pull rope 17 is provided in the connecting channel. One end of the pull rope 17 is fixedly connected to the pull rod 15, and a pull ring is fixedly installed on the other end of the pull rope 17.
[0036] In this embodiment, when the pull rod 15 needs to be operated, the user only needs to pull the pull ring. The pull ring drives the pull rope 17 to move, and the pull rope 17 in turn pulls the pull rod 15, causing the pull rod 15 to move the positioning block 6 to one side, away from the connecting rod 5. At the same time, the spring 16 contracts. Then, the storage box 4 can be installed. After installation, the pull ring is released. Under the elastic force of the spring 16, the positioning block 6 returns to its original position and limits the connecting rod 5, completing the installation of the storage box 4. When the storage box 4 needs to be disassembled, the pull ring is pulled again to move the positioning block 6 away from the connecting rod 5, and the storage box 4 can be removed. By setting the pull rope 17 and the pull ring, the user does not need to directly contact the pull rod 15. He only needs to pull the pull ring from the outside of the storage box 4 to operate the pull rod 15.
[0037] In a further preferred embodiment of this utility model, a connection port is provided on one side of the storage box 4, the connection port extends into the connection groove 14, and a limiting rod 18 for limiting the pull rod 15 is slidably provided in the connection port. Two limiting ports are provided at the bottom of the pull rod 15, and both limiting ports are adapted to the limiting rod 18. Magnet pieces 19 are installed on both the connection port and the limiting rod 18, and a group of magnet pieces 19 are attracted to each other.
[0038] In this embodiment, before pulling the pull rope 17, the limiting rod 18 must be pulled first to slide the limiting rod 18 away from the limiting port of the pull rod 15. Then, the pull rope 17 is pulled. After the positioning block 6 slides away from the connecting rod 5, the limiting rod 18 is inserted into another limiting port to limit the pull rod 15 and ensure that the spring 16 will not reset. This facilitates the subsequent installation of the storage box 4. The design of the limiting rod 18 and the limiting port provides additional limiting protection for the movement of the pull rod 15. Through the adsorption effect of the magnetic piece 19, the limiting rod 18 is more secure in the limiting position and is not easy to loosen due to external vibration or collision.
[0039] In summary, compared with related technologies, this handheld power quality analyzer has advantages such as shock resistance, convenient accessory storage, and stable and reliable connection, which can effectively protect the analyzer and facilitate user operation.
