Abstract
Description
Technical Field
[0001] This utility model relates to the field of inverter technology, and in particular to an anti-theft device for inverters. Background Technology
[0002] An inverter is a power conversion device used to switch between direct current (DC) and alternating current (AC). With the diversification of energy structures, the demand for inverters in applications such as photovoltaic power generation and wind power generation is increasing, and their application scope is constantly expanding. Currently, inverters are usually installed in outdoor open-air locations, often in relatively remote areas. This installation characteristic leads to a higher risk of theft for inverters, thereby affecting the overall safety and reliability of the equipment operation.
[0003] To enhance security against theft, some technologies employ mechanical locks such as padlocks and chain locks to temporarily bind the inverter to nearby fixed objects, such as brackets or bases, during on-site installation. This not only affects the overall aesthetics of the equipment but also hinders standardized installation and maintenance. Alternatively, some technologies use welding or riveting to permanently fix the inverter to the fixed object, making it difficult to disassemble from the outside. However, this increases the difficulty and cost of on-site replacement and repair, and reduces the flexibility of inverter deployment and management. Utility Model Content

[0027] The present invention will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0028] In the description of this utility model, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this utility model.
[0029] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection, a contact connection, or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0030] An anti-theft device 1 for an inverter, such as Figures 1-5 As shown, the device includes a base 10 and a lock box 20. The base 10 is fixed to the installation location 3. The base 10 has a placement cavity 111 and a lock hole 112 communicating with the placement cavity 111. The lock box 20 is accommodated in the placement cavity 111. The lock box 20 has a retractable latch 221, which is detachably inserted into the lock hole 112 so that the lock box 20 is detachably fixed to the base 10. When the lock box 20 is fixed to the base 10, the anti-theft device 1 can block the installation parts of the inverter 2.
[0031] In other words, when the latch 221 of the lock box 20 is inserted into the lock hole 112 of the base 10, the lock box 20 is fixed in the base 10, and the anti-theft device 1 can cover the mounting parts of the inverter 2, which helps to prevent the mounting parts from being exposed, thereby reducing the risk of the inverter 2 being stolen when it is installed outdoors. Furthermore, when the lock box 20 is unlocked by means of key, fingerprint, password, etc., and the latch 221 of the lock box 20 is separated from the lock hole 112 of the base 10, the lock box 20 can be taken out from the placement cavity 111. Thus, by removing the anti-theft device 1, the mounting parts of the inverter 2 can be exposed, making it easier to replace and repair the inverter 2, reducing the difficulty and cost of replacing and repairing the inverter 2 on site.
[0032] It is understandable that the use of the anti-theft device 1 as an independent accessory helps to avoid changing the structure and function of the existing inverter 2, thereby improving the applicability of the anti-theft device 1, reducing the application cost of the anti-theft device 1, and also facilitating standardized installation and maintenance, as well as improving the overall aesthetics of the equipment.
[0033] It is worth mentioning that the installation location 3 includes, but is not limited to, surfaces such as walls, cabinets, and frames, which improves the flexibility of installing the anti-theft device 1 and the flexibility of deploying and managing the inverter 2.
[0034] In some embodiments, such as Figure 3 and Figure 4 As shown, the base 10 has a maintenance hole 113 on its side wall facing the inverter 2. The maintenance hole 113 allows the mounting components of the inverter 2 to be exposed and allows tools adapted to the mounting components to pass through. That is, when the lock box 20 is fixed to the base 10, the lock box 20 can cover the maintenance hole 113, thereby helping to prevent the mounting components of the inverter 2 from being exposed. When the lock box 20 is removed from the placement cavity 111, the mounting components of the inverter 2 are exposed through the maintenance hole 113, and the maintenance hole 113 allows tools adapted to the mounting components, such as screwdrivers and hex wrenches, to pass through. This allows the mounting components to be installed and removed without disassembling the base 10, making it more convenient to replace and repair the inverter 2, and further reducing the difficulty and cost of replacing and repairing the inverter 2 on-site.
[0035] In some embodiments, such as Figure 3 and Figure 4 As shown, the lock box 20 includes a box body 21 and a lock body 22. The box body 21 is accommodated within the placement cavity 111, filling the cavity and preventing the lock box 20 from moving relative to the base 10, thus improving the reliability of the connection between the lock box 20 and the base 10. Furthermore, the lock body 22 is fixed to the box body 21 and includes a latch 221. When the box body 21 is accommodated in the placement cavity 111, the latch 221 is positioned opposite to the lock hole 112, allowing for detachable insertion into the lock hole 112.
[0036] In other words, the maintenance hole 113 on the base 10 can be covered by the box 21, which helps to prevent the installation parts of the inverter 2 from being exposed; and, through the cooperation between the box 21 and the base 10, the relative position of the lock tongue 221 of the lock body 22 and the lock hole 112 can be positioned, so that the lock tongue 221 can be inserted into or separated from the lock hole 112.
[0037] This should be understandable, such as Figure 4As shown, the housing 21 and lock body 22 are separate units, allowing them to be manufactured or procured independently. Specifically, the housing 21 and its compatible base 10 can be adapted to different inverter models and installation environments, meaning the dimensions of the housing 21 and base 10 can be flexibly adjusted to expand the applicability of the anti-theft device 1. Furthermore, the lock body 22 can utilize existing products on the market, reducing the design, development, and manufacturing costs of the anti-theft device 1. Additionally, when the lock body 22 or lock cylinder 222 is damaged, it can be replaced individually, further reducing the usage and maintenance costs of the anti-theft device 1.
[0038] It is worth mentioning that the box body 21 and the lock body 22 can also be set as a whole, thereby improving the reliability of the connection between the box body 21 and the lock body 22 and further increasing the anti-theft security of the anti-theft device 1. This application does not impose specific restrictions on this.
[0039] In some embodiments, such as Figure 4 , Figure 6 and Figure 7 As shown, the housing 21 has a through mounting hole 2111; the lock body 22 includes a lock cylinder 222, which drives the bolt 221 to extend and retract. The lock cylinder 222 is fixed to the mounting hole 2111, and the keyhole of the lock cylinder 222 protrudes from one end of the mounting hole 2111. The bolt 221 can be inserted into the lock hole 112 of the base 10 through the other end of the mounting hole 2111. That is, by turning the lock cylinder 222 with a key adapted to the keyhole, the bolt 221 can be detachably inserted into the lock hole 112, thereby fixing the lock housing 20 in the base 10, or allowing the lock housing 20 to be removed from the base 10.
[0040] In some embodiments, such as Figure 6 and Figure 7 As shown, the housing 21 has a positioning groove 2112 located around the assembly hole 2111; the lock body 22 includes a fixing part 223 connected to the lock cylinder 222, which is placed in the positioning groove 2112 and connected to the housing 21. That is, when the fixing part 223 is placed in the positioning groove 2112 and connected to the housing 21, the lock cylinder 222 passes through the assembly hole 2111, so that the keyhole of the lock cylinder 222 protrudes from the other end of the assembly hole 2111. It should be understood that by accommodating the fixing part 223 of the lock body 22 in the positioning groove 2112, the structure of the lock housing 20 becomes more compact, thereby reducing the overall size of the anti-theft device 1. Furthermore, during the assembly of the lock body 22 and the housing 21, the positioning groove 2112 serves as an auxiliary limiting mechanism, thereby reducing assembly difficulty and improving assembly efficiency.
[0041] In at least one embodiment, when the fixing part 223 is placed in the positioning groove 2112, the surface of the fixing part 223 is flush with the surface of the box body 21, or the surface of the fixing part 223 is slightly lower than the surface of the box body 21. This helps to avoid interference between the fixing part 223 and the base 10 during the process of placing the lock box 20 into the base 10; it also allows the box body 21 to fit snugly against the base 10, thereby improving the reliability of the connection between the box body 21 and the base 10 and helping to prevent the lock box 20 from shaking in the base 10.
[0042] In some embodiments, such as Figure 4 and Figure 5 As shown, the keyhole 112 is located on the side wall of the base 10 facing the inverter 2. That is, when the lock box 20 is fixed to the base 10, the latch 221 extends into the keyhole 112. The latch 221 is located on the side of the anti-theft device 1 closer to the inverter 2, which helps to prevent the latch 221 from being damaged, thereby improving anti-theft security. Furthermore, the base 10 has an opening slot 114 on the side wall away from the inverter 2. The opening slot 114 is positioned opposite to the keyhole 112. When the lock box 20 is fixed to the base 10, the keyhole of the lock cylinder 222 can be exposed from the opening slot 114, which facilitates locking and unlocking operations by construction personnel.
[0043] In at least one embodiment, such as Figure 4 and Figure 5 As shown, when the lock box 20 is accommodated in the placement cavity 111, at least a portion of the lock cylinder 222 extends into the opening slot 114, making the overall structure of the anti-theft device 1 more compact. Furthermore, the opening of the opening slot 114 is located at the upper edge of the lock box 20, so as to facilitate the insertion of the lock box 20 from top to bottom into the placement cavity 111 of the base 10, thereby improving the ease of installation of the anti-theft device 1.
[0044] In at least one embodiment, such as Figure 8 As shown, the opening slot 114 and the maintenance hole 113 are also arranged opposite to each other. The mounting parts of the inverter 2 can be exposed through the maintenance hole 113 and the opening slot 114. The opening slot 114 allows tools adapted to the mounting parts to pass through, so that the mounting parts can be installed and removed without disassembling the base 10, making it easier to replace and repair the inverter 2.
[0045] In some embodiments, such as Figure 4 and Figure 6 As shown, the box 21 includes a main body 211 and a limiting part 212. The main body 211 fills the placement cavity 111. The limiting part 212 extends from at least one side of the main body 211 toward the base 10. When the lock box 20 is fixed to the base 10, the limiting part 212 abuts against the inner wall of the base 10, so that the construction personnel can confirm that the lock box 20 has been placed in place, thereby improving the installation efficiency.
[0046] In at least one embodiment, such as Figure 6 As shown, the longer opposite sides of the main body 211 are respectively connected to limiting parts 212, which makes the force between the box 21 and the base 10 more balanced, improves the stability of the lock box 20 placed in the base 10, and helps to prevent the lock box 20 from tilting in the placement cavity 111. Furthermore, the length of the limiting part 212 is less than or equal to the length of the side of the connected main body 211, thereby reducing the mating length between the box 21 and the base 10, which helps to avoid interference at the corners of the box 21 and the base 10, and reduces the processing difficulty of the lock box 20.
[0047] In some embodiments, such as Figure 4 and Figure 8 As shown, the base 10 has a mounting hole 115, which is suitable for the fastener 30 to pass through, so that the base 10 is fixed to the installation location 3. When the lock box 20 is fixed to the base 10, the lock box 20 can cover the fastener 30. Specifically, as shown... Figure 4 and Figure 5 As shown, the fastener 30 extends outward from the placement cavity 111 through the mounting hole 115 and can be screwed into the installation location 3, thereby fixing the base 10 to the installation location 3. It is worth mentioning that the head of the fastener 30 remains inside the placement cavity 111. When the lock box 20 is accommodated inside the placement cavity 111, the lock box 20 can cover the head of the fastener 30, which helps to prevent the fastener 30 from being disassembled, thereby improving the anti-theft security of the anti-theft device 1.
[0048] In some embodiments, such as Figure 4 and Figure 8 As shown, mounting holes 115 are symmetrically provided on the opposite side walls of the base 10, allowing both the left and right sides of the base 10 to be used for installation and fixation. This improves the installation flexibility and compatibility of the anti-theft device 1, and expands its application range. It should be understood that while one mounting hole 115 is used to allow a fastener 30 to pass through and be screwed into the installation location 3, the other mounting hole 115 allows tools, such as a screwdriver, to pass through, facilitating installation operations, reducing the difficulty of installing the anti-theft device 1, and improving the efficiency of on-site installation.
[0049] Furthermore, such as Figure 4 As shown, the mounting hole 115, lock hole 112, and maintenance hole 113 are arranged on opposite sides, which makes the structural strength of each side wall of the base 10 more uniform and improves the structural reliability of the base 10. In addition, it also makes the position distribution of the fastener 30, the box 21 and the lock body 22 in the placement cavity 111 more reasonable, making the structure of the anti-theft device 1 more compact.
[0050] In some embodiments, such as Figure 4 , Figure 5 and Figure 8 As shown, the base 10 includes an outer wall portion 11 and an elastic portion 12. The outer wall portion 11 defines a placement cavity 111 to accommodate the lock box 20. The elastic portion 12 extends into the placement cavity 111 from the upper edge of the outer wall portion 11, bent. When the lock box 20 is accommodated in the placement cavity 111, the elastic portion 12 can elastically deform and abut against the lock box 20. It should be understood that the length of the box body 21 is slightly less than the length of the placement cavity 111 of the base 10, thereby allowing room for the head of the fastener 30. When the lock box 20 is accommodated in the placement cavity 111, the elastic portion 12 can elastically deform and abut against the lock box 20, which provides the lock box 20 with leeway for adjusting its position in the placement cavity 111, reducing the installation difficulty of the anti-theft device 1; it also helps to prevent the lock box 20 from moving relative to the extension direction of the base 10, improving the connection reliability between the lock box 20 and the base 10.
[0051] It is worth mentioning that the elastic part 12 may be provided only on the upper edge of one of the side walls of the outer wall part 11, for example, on one of the side walls with the mounting hole 115; the elastic part 12 may also be provided on the upper edges of two opposite side walls of the outer wall part 11, and this application does not make specific restrictions on this.
[0052] In some embodiments, the base 10 and the box 21 are sheet metal parts or plastic parts, which helps to reduce manufacturing costs.
