Description

Technical Field

[0001] This utility model relates to the field of flame-retardant PP shell technology, and in particular to a flame-retardant PP shell structure for electronic devices. Background Technology

[0002] In the use of electronic devices, flame-retardant PP housings are often used to protect core components such as electronic connectors due to their excellent flame retardancy and insulation. The mounting box housing the electronic connectors is a crucial part of this housing. To prevent the electronic connectors inside the mounting box from being affected by dust or external impacts, a protective plate is usually installed at the front of the mounting box. This plate provides physical protection for the internal connectors while ensuring the overall flame-retardant protection of the housing. These protective plates need to be adaptable to the daily maintenance needs of electronic devices, allowing them to be opened for maintenance or connector insertion / removal, and kept closed during normal use. Therefore, the ease of installation and removal, and the flexibility of opening and closing the protective plate, are key factors affecting the user experience of flame-retardant PP housings.

[0003] Currently, most protective plates used on the front end of electronic connector mounting boxes are fixed with bolts or closed with a single snap-fit. When bolted, disassembly and assembly require specialized tools, making the process cumbersome. Especially in emergency maintenance scenarios, the lack of tools can directly delay disassembly and assembly efficiency. While a single snap-fit ​​structure requires no tools, it can only achieve two states: fully closed or fully open. It cannot adjust the opening degree of the protective plate according to maintenance needs. For example, when only a single connector needs to be inserted or removed, the protective plate still needs to be completely removed, easily exposing other connectors and increasing the risk of dust contamination or accidental contact. Furthermore, the connection structure between some protective plates and the mounting box is complex, and after long-term use, jamming can easily occur, further affecting the stability of disassembly, assembly, and opening / closing.

[0004] Therefore, a new flame-retardant PP housing structure for electronic devices is proposed to solve the above problems. Utility Model Content

[0005] 1. Technical problems to be solved The purpose of this invention is to provide a flame-retardant PP shell structure for electronic devices, solving the problem that most protective plates used in the front end of electronic connector mounting boxes currently employ bolt fixing or a single snap-fit ​​closure method. When bolt fixing is used, disassembly and assembly require specialized tools, making the operation cumbersome, especially in emergency maintenance scenarios where the lack of tools directly delays disassembly and assembly efficiency. While the single snap-fit ​​structure requires no tools, it can only achieve two states: fully closed or fully open, making it impossible to adjust the opening degree of the protective plate according to maintenance needs. For example, when only a single connector needs to be inserted or removed, the protective plate still needs to be completely removed, easily exposing other connectors and increasing the risk of dust contamination or accidental contact. Furthermore, the connection structure between some protective plates and the mounting box is complex, and after long-term use, jamming is prone to occur, further affecting the stability of disassembly, assembly, and opening / closing.

[0006] 2. Technical Solution To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a flame-retardant PP shell structure for electronic devices, comprising a base plate, a mounting box mounted on the base plate, a protective plate mounted on one end of the mounting box, two mounting plates mounted on the base plate, each mounting plate having a first sliding groove, each first sliding groove having multiple symmetrical second sliding grooves at both ends, each mounting plate having a first slider with a third sliding groove extending through it, each first slider having a fourth sliding groove at both ends, each mounting plate passing through a corresponding third sliding groove, each fourth sliding groove having a second slider mounted therein, each first sliding groove having a fixing block with two symmetrical mounting grooves at both ends, each mounting groove having a spring fixedly mounted therein, the other end of each spring being connected to the end of the corresponding second slider near the fixing block, each first slider having two symmetrical third sliders mounted at its bottom, each third slider being mounted in a corresponding second sliding groove, and each first slider having an end near the mounting box connected to the end of the protective plate away from the mounting box.

[0007] Furthermore, each of the third sliders has two first threaded holes at the end furthest from the mounting box, and each of the fixing blocks has a second threaded hole. A bolt is fitted into each of the first threaded holes and the corresponding second threaded holes. This design allows for quick disassembly of the fixing block and the two corresponding second sliders, facilitating their maintenance.

[0008] Furthermore, a sealing element is installed on the base plate, the sealing element is located directly below the protective plate, the sealing element is connected to the end of the mounting box near the mounting plate, and a sealing gasket is installed on the bottom of the inner side wall of the sealing element. This design can increase the tightness between the protective plate and the mounting box.

[0009] Furthermore, the mounting box has multiple heat dissipation grooves at the end away from the first slider, and each of the heat dissipation grooves is angled. This design can reduce the temperature inside the mounting box in real time, and the angled design can prevent some objects from entering the mounting box through straight movement and damaging the electronic connectors inside.

[0010] Furthermore, the mounting box is provided with a connection hole, and a cooler is installed on the outer surface of the mounting box away from the first slider. The cooler is connected to the connection hole. This design allows the cool air generated by the cooler to be sent into the mounting box through the connection hole, thereby acting on the electronic connector to quickly cool it down.

[0011] Furthermore, a temperature sensor is installed on the inner side wall of the mounting box. The signal output terminal of the temperature sensor is connected to the signal input terminal of the air cooler. This design can monitor the temperature inside the mounting box in real time, and control the air cooler to start working when the temperature exceeds the threshold.

[0012] Furthermore, anti-slip pads are installed at the four corners of the bottom of the base plate. Since the base plate, mounting box, and protective plate are all made of flame-retardant PP material, this design can prevent the entire device from sliding on the table or the ground, while also preventing the bottom of the base plate from directly contacting damp surfaces.

[0013] Furthermore, a handle is installed at the end of the mounting box away from the base plate, a design that makes it convenient for operators to lift the outer casing by hand.

[0014] 3. Beneficial effects Compared with existing technologies, the advantages of this utility model are: This flame-retardant PP shell features an optimized disassembly and adjustment mechanism for the protective plate. Firstly, it eliminates the need for specialized tools, allowing operators to quickly assemble and disassemble the protective plate by hand, significantly simplifying the operation process and improving the efficiency of daily maintenance and emergency repairs, while avoiding the limitations imposed by tool reliance. Secondly, the protective plate's opening degree can be adjusted according to actual needs, allowing it to be fully opened for comprehensive maintenance or partially closed when only certain connectors need to be operated. This reduces the exposure of unoperated connectors, lowers the risk of dust contamination and accidental contact, and ensures the safety of electronic connectors. Furthermore, the simple design is compatible with the material properties of the flame-retardant PP shell, preserving its original flame-retardant properties and overall structural stability, thus meeting the long-term usage requirements of electronic devices.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0023] Please see Figure 1-7As shown, this embodiment is a flame-retardant PP shell structure for electronic devices, including a base plate 110, a mounting box 120 mounted on the base plate 110, a protective plate 250 mounted at one end of the mounting box 120, two mounting plates 210 mounted on the base plate 110, each mounting plate 210 having a first sliding groove 211, and each first sliding groove 211 having multiple symmetrical second sliding grooves 212 at both ends, each mounting plate 210 having a first slider 220 mounted on it, the first slider 220 having a third sliding groove 221 extending through it, each first slider 220 having a fourth sliding groove 222 at both ends, and each mounting plate 210 extending through the corresponding third sliding groove 222. Within 21, a second slider 230 is installed in any of the fourth sliding grooves 222 shown. A fixing block 240 is installed in the first sliding groove 211. Two symmetrical mounting grooves 232 are opened at both ends of the fixing block 240. A spring 241 is fixedly installed in any of the mounting grooves 232. The other end of each spring 241 is connected to the end of the corresponding second slider 230 near the fixing block 240. Two symmetrical third sliders 231 are installed at the bottom of any of the first sliders 220. Each third slider 231 is installed in the corresponding second sliding groove 212. The end of each first slider 220 near the mounting box 120 is connected to the end of the protective plate 250 away from the mounting box 120. Each of the third sliders 231 has two first threaded holes 223 at the end away from the mounting box 120, and each of the fixing blocks 240 has a second threaded hole 242. A bolt 243 is fitted into each of the first threaded holes and the corresponding second threaded holes 242. A sealing element 130 is installed on the base plate 110, located directly below the protective plate 250. The sealing element 130 is connected to the end of the mounting box 120 near the mounting plate 210, and a sealing gasket 131 is installed on the bottom of the inner wall of the sealing element 130. Anti-slip pads 190 are installed at the four corners of the bottom of the base plate 110. A handle 180 is installed at the end of the mounting box 120 away from the base plate 110.

[0024] Working principle: When the protective plate 250 needs to be moved up or down, simply grasp the two sets of second sliders 230 and squeeze them inward. When the two second sliders 230 move relative to each other, they will drive the third slider 231 to move synchronously. When the third slider 231 moves inward, it will disengage from the second sliding groove 212. At this time, the second slider 230 can drive the first slider 220 to move up or down. When the two first sliders 220 move, they can drive the protective plate 250 to move. When it moves to the corresponding position, release the grip on the third slider 231. When released, the elastic potential energy stored in the two sets of springs 241 will push the corresponding second slider 230 outward. When the second slider 230 moves, it will drive the corresponding third slider 231 into the corresponding second sliding groove 212 and lock it in place, thereby effectively preventing the first slider 220 from moving and ultimately fixing the protective plate 250.

[0025] Multiple heat dissipation grooves 170 are formed at the end of the mounting box 120 away from the first slider 220, and each of the heat dissipation grooves 170 is angled. A connection hole 150 is provided on the mounting box 120, and a cooler 160 is mounted on the outer surface of the mounting box 120 away from the first slider 220, the cooler 160 being connected to the connection hole 150. A temperature sensor 140 is mounted on the inner wall of the mounting box 120, and the signal output terminal of the temperature sensor 140 is connected to the signal input terminal of the cooler 160.

[0026] Working principle: During use, the temperature sensor 140 monitors the temperature inside the mounting box 120 in real time. When the temperature exceeds the threshold, it controls the air cooler 160 to start working. The air cooler 160 then sends cold air into the mounting box 120 through the connection hole 150 and applies it to the electronic connector to quickly cool it down.
