Description

Technical Field

[0001] This utility model relates to the field of heat dissipation equipment technology, and in particular to a louver slat fixing device and a louver. Background Technology

[0002] The rectifier module of a charging station is a crucial component that converts alternating current (AC) to direct current (DC). It mainly consists of components such as a rectifier, filter, inverter, and transformer. During operation, the rectifier module generates a significant amount of heat, and the accumulation of this heat directly affects the performance, safety, and lifespan of the rectifier module and even the entire charging station. Currently, the mainstream heat dissipation method for rectifier modules is to install louvers in the side walls of the charging station, thereby generating convection within the station to achieve heat dissipation.

[0003] Currently, the main methods for fixing venetian blinds are screw fixing, screw-hinge combination fixing, or slot fixing. These fixing methods all have certain drawbacks, specifically:

[0004] Traditional screw fixing methods and their derivatives require complete disassembly of the louvers for later maintenance, increasing the time spent on overhauling the charging pile's rectifier module. Frequent disassembly and reassembly also easily lead to thread stripping. The combined screw and hinge structure not only increases the complexity of the production process but also prolongs the overall assembly time, resulting in a simultaneous increase in manufacturing costs and warehousing management difficulties. While traditional slot structures simplify the assembly process, the irregular shapes of the louvers often necessitate the creation of multiple molds to obtain slots that fit the louvers. This leads to low utilization rates of both slots and louvers, drastically increasing mold costs. Furthermore, the high-precision assembly requirements between these slots and louvers not only drive up manufacturing costs but also result in high defect rates, forcing companies to add visual aids to maintain slot production capacity, further increasing manufacturing costs.

[0028] The first fixing plate 1 and the second fixing plate 2 are respectively provided with a plurality of first fixing parts 15 and second fixing parts 23 at intervals. The first fixing parts 15 and the second fixing parts 23 are arranged opposite to each other. A first limiting groove 151 is formed between two adjacent first fixing parts 15, and a second limiting groove 231 is formed between two adjacent second fixing parts 23. The first limiting groove 151 and the second limiting groove 231 are staggered to form a clamping groove 3 for tilting and accommodating the fixed louver slats between adjacent first limiting grooves 151 and second limiting grooves 231.

[0029] Compared with the prior art, the louver slat fixing device proposed in this utility model includes a first fixing plate 1 and a second fixing plate 2 connected to the first fixing plate 1. The first fixing plate 1 and the second fixing plate 2 are respectively provided with a plurality of first fixing parts 15 and second fixing parts 23 at intervals. A first limiting groove 151 and a second limiting groove 231 are formed between adjacent first fixing parts 15 and between adjacent second fixing parts 23, respectively. The relative arrangement of the first fixing parts 15 and the second fixing parts 23 and the staggered arrangement of the first limiting groove 151 and the second limiting groove 231 form a clamping groove 3 for accommodating and fixing louver slats 4 of different shapes. The main body of the louver slat 4 is inclined and abutted by the first fixing parts 15 and the second fixing parts 23 in the clamping groove 3. The two ends of the louver slat 4 abut against the first limiting groove 151 and the second limiting groove 231, respectively, thereby being stably fixed in the clamping groove 3. The design of the first limiting groove 151 and the second limiting groove 231 provides redundant snap-fit ​​space at both ends of the louver slat 4, which is beneficial for accommodating louver slats 4 of different shapes. The louver slat fixing device of this utility model makes the insertion and placement of the louver slat 4 simple and easy, and enhances the compatibility of louver slats 4 of different specifications and the louver slat fixing device. At the same time, the louver slat fixing device of this utility model has low manufacturing cost, which is conducive to cost saving and promotion of production.

[0030] In summary, the louver slat fixing device of this utility model has significant advantages such as convenient and stable installation, strong compatibility, and low cost.

[0031] See Figures 2 to 4 As shown, optionally, both the first fixing part 15 and the second fixing part 23 are trapezoidal structures. The slope of the trapezoidal structure fits the main shape of the louver slat 4 better, and can better fix the louver slat 4.

[0032] Furthermore, see Figure 4 and Figure 5 As shown, in order to further enhance the fixing strength and stability of the venetian blind 4, the shapes of the first fixing part 15 and the second fixing part 23 can be changed according to the actual shape of the venetian blind 4, so that the first fixing part 15 and the second fixing part 23, the first limiting groove 151 and the second limiting groove 231 can tightly abut against the main body and both ends of the venetian blind 4.

[0033] See Figures 1 to 7 As shown, the first fixing plate 1 further includes a first frame 11, a second frame 12, a third frame 13 corresponding to the first frame 11, and a fourth frame 14 corresponding to the third frame 13.

In this embodiment, the flexible interlocking between the detachable first fixing strip 21 and the first frame 11, the second fixing strip 22 and the second frame 12 greatly reduces the difficulty of installing the louver slats 4, which is beneficial to improving assembly efficiency.

[0035] Optionally, the third frame 13 is an integral structure adapted to the shape of the louver slat 4. This arrangement conforms to the tilt direction of the top louver slat 4, which is beneficial for the assembly of the top first louver slat 4.

[0036] Optionally, the fourth frame 14 has a four-bend integrated structure. The first bend 141 of the fourth frame 14 is fixedly connected to the first frame 11 and the second frame 12. The second bend 142 and the third bend 143 of the fourth frame 14 form a receiving groove 16 for accommodating dirt. The fourth bend 144 of the fourth frame 14 is flush with the height of the first bend 141 and the second frame 12 and extends outward to form a mounting plate 17 for mounting the first fixing plate 1. In this embodiment, the mounting plate 17 is used to mount the louver slat fixing device of this embodiment.
