Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electronic instrument chassis, in particular to an anti-interference and anti-electric leakage electronic instrument chassis. Background Technique
[0002] The anti-interference and anti-electric leakage electronic instrument chassis is made of titanium alloy material, which has a poor conductive effect, can prevent external signals from interfering with the instruments inside the chassis, and at the same time avoid the current from being conducted out after internal electric leakage. The internal electronic components are installed in a relatively narrow chassis. Through orderly arrangement, it has the effect of preventing the circuit from touching the power supply shell and preventing the exposed components from contacting the shell to cause electric leakage.
[0003] However, most of the installation of components inside the chassis is in a threaded fixing manner. The space inside the chassis is relatively narrow. When operating manually, the space for the hand to reach into the chassis is limited. When fixing with threads, it is easily blocked by the inner wall of the chassis. Therefore, it is not easy to perform rotational fixing operation inside the chassis by hand. Moreover, the chassis needs to dissipate heat inside, so heat dissipation holes are provided for heat emission. The positions of the heat dissipation holes are connected to the outside. When water is accidentally splashed on the chassis, the water easily enters the inside quickly through the heat dissipation holes, thus affecting the normal use of the internal components. Content of the Utility Model
[0004] In view of the deficiencies of the prior art, the present utility model is realized through the following technical solutions: An anti-interference and anti-electric leakage electronic instrument chassis, the structure of which includes a handle, a heat dissipation mechanism, a support plate, and a box body. The handle is embedded on the side surface of the support plate. The support plate is installed on the left and right sides of the box body. The heat dissipation mechanism is embedded inside the upper end of the box body. The box body is provided with a moving mechanism, a disassembly plate, a box plate, and a circuit hole. The disassembly plate is fixed to the side surface of the box plate by threads. The moving mechanism is installed at the bottom end inside the box plate. The circuit hole is located inside the disassembly plate. The heat dissipation mechanism is embedded on the upper end of the box plate. The support plate is embedded on the side surface of the box plate. The moving mechanism is in a horizontal state. The circuit hole is in a square state and is evenly distributed at the position of the disassembly plate according to the instrument circuit.
[0005] As a further optimization of this technical solution, the moving mechanism is provided with a limit block, a flat plate, a fixing plate, a support block, and a moving plate. The limit block is embedded on the surface of the fixing plate. The moving plate is in extrusion fit with the limit block. The flat plate is parallel to the moving plate. The support block is installed on the upper end of the moving plate. The flat plate is embedded on the upper end of the support block. The fixing plate is installed at the bottom end inside the box plate. The inner side of the box plate is provided with a horizontal track, and the right side of the track is in an open state. There are two limit blocks, symmetrically distributed on the left and right sides of the surface of the fixing plate. The lower end of the moving plate is provided with circular rods, which are horizontally arranged and evenly distributed, and the gap between every two circular rods is the width of the limit block. There is a gap between the support blocks, which has a heat dissipation effect.
[0006] As a further optimization of the technical solution, the limit block is provided with an arc plate, a spring, a connecting plate, and a concave plate. The arc plate is fixedly embedded at the upper end of the connecting plate. The lower surface of the connecting plate is attached to the upper end of the concave plate. The lower end of the connecting plate is installed inside the middle of the concave plate. The upper end of the spring is fixedly embedded at the lower end of the middle of the connecting plate. The concave plate is fixedly embedded on the surface of the fixing plate. The moving plate is in extrusion fit with the arc plate. The arc plate is made of aluminum alloy and has the characteristics of strong toughness and easy deformation and bending. The connecting plate is made of rubber and has the effect of being able to stretch and deform.
[0007] As a further optimization of the technical solution, the heat dissipation mechanism is provided with a gap plate, a flow channel, and an inclined plate. The flow channel is located inside the inclined plate. The inclined plates are installed on the left and right sides of the gap plate. The gap plate is fixedly embedded inside the upper end of the box body. There are two inclined plates distributed vertically at one gap position of the inclined plate, and they are distributed in a state of inclining 25 degrees to the horizontal line to the left and right respectively. The inclined plates on the left and right sides of the gap plate are distributed in a high and low state. The flow channels are distributed in a staggered state at the positions of the upper and lower two inclined plates.
[0008] As a further optimization of the technical solution, the flat plate is internally provided with hollow grooves that penetrate through the flat plate, and the hollow grooves are arranged at intervals and have the effect of circulating air. Beneficial effects
[0009] Compared with the prior art, the electronic instrument chassis of the present utility model for anti-interference and anti-electric leakage has the following advantages:
[0010] In the present utility model, when the right side of the moving plate is manually pulled out, then under the compressive deformation of the connecting plate, the circular rod slides through on the surface of the arc plate. When the moving plate needs to be fixed, the movement is stopped. Further, the middle of the connecting plate generates an upward tensile force, causing the left and right ends of the arc plate to generate an inward tensile deformation on the connecting plate. Then the middle position of the arc plate pops up upward, causing the arc plate to be squeezed and fixed at the gap position between the circular rods. Further, when the electronic instrument is fixed on the surface of the flat plate by threading, it is more stable, so that it is convenient for the manual threading installation of the electronic instrument for the pulled-out moving plate, and it is avoided that the space inside the box plate is too narrow to be easily fixed by manual threading and rotating operation.
[0011] In the present utility model, the splashed water enters the gap of the gap plate from above, and the water flows toward the inclined plate on the side of the gap plate and is blocked on the inclined inclined plate. At the same time, the water enters the position of the lower inclined plate after passing through the flow channel in the upper inclined plate. Since the flow channels are distributed in a staggered state at the upper and lower positions of the inclined plate, the water will be blocked at the inclined position of the lower inclined plate. Further, through the multiple staggered blockings at the positions of the two inclined plates, it is avoided that the splashed water flows into the inside of the box plate.

Specific Embodiments
[0019] To make the technical means, creative features, achieved objectives, and functions of the present utility model easy to understand, the preferred implementation schemes of the present utility model are further elaborated below in combination with specific embodiments and the accompanying drawings. Embodiment
[0020] Please refer to Figures 1 - 5, the present utility model provides an electronic instrument chassis with anti-interference and anti-electric leakage functions. Its structure includes a handle 1, a heat dissipation mechanism 2, a support plate 3, and a box body 4. The handle 1 is embedded on the side of the support plate 3. The support plate 3 is installed on both the left and right sides of the box body 4. The heat dissipation mechanism 2 is embedded inside the upper end of the box body 4. The box body 4 is provided with a movable mechanism 41, a disassembly plate 42, a box plate 43, and a wiring hole 44. The disassembly plate 42 is fixed to the side of the box plate 43 by threads. The movable mechanism 41 is installed at the inner bottom end of the box plate 43. The wiring hole 44 is located inside the disassembly plate 42. The heat dissipation mechanism 2 is embedded at the upper end of the box plate 43. The support plate 3 is embedded on the side of the box plate 43. The movable mechanism 41 is in a horizontal state, and the wiring hole 44 is in a square state, evenly distributed at the position of the disassembly plate 42 according to the instrument wiring. Thus, by using a screwdriver tool to unscrew the fixation of the disassembly plate 42, after opening the disassembly plate 42, the movable mechanism 41 is pulled out inside the box plate 43, and the electronic instrument is fixed to the surface of the movable mechanism 41 by threads. Then, the movable mechanism 41 is pushed into the box plate 43 to achieve the fixation of the electronic instrument. And by holding the handle 1, the box body 4 connected to the support plate 3 is moved. The heat dissipated by the electronic instrument inside the box plate 43 is discharged upward to the position of the heat dissipation mechanism 2. The heat dissipation mechanism 2 can dissipate the heat while preventing the water splashed from the outside from flowing into the box plate 43.
[0021] The movable mechanism 41 is provided with a limit block w1, a flat plate w2, a fixing plate w3, a support block w4, and a moving plate w5. The limit block w1 is embedded on the surface of the fixing plate w3. The moving plate w5 is in extrusion fit with the limit block w1. The flat plate w2 is parallel to the moving plate w5. The support block w4 is installed at the upper end of the moving plate w5. The flat plate w2 is embedded at the upper end of the support block w4. The fixing plate w3 is installed at the inner bottom end of the box plate 43. There is a horizontal track inside the box plate 43, and the right side of the track is in an open state. There are two limit blocks w1, symmetrically distributed on the left and right sides of the surface of the fixing plate w3. The lower end of the moving plate w5 is provided with circular rods, horizontally arranged and evenly distributed, and the gap size between every two circular rods is the width size of the limit block w1. There is a gap between the support blocks w4, which has a heat dissipation effect. Thus, manually pull out the right side of the moving plate w5, so that the circular rods at the lower end of the moving plate w5 move horizontally and slide out inside the track. Thus, the circular rods are in extrusion activity with the limit blocks w1 on the surface of the fixing plate w3. After the moving plate w5 is translated, the limit block w1 on the right side of the fixing plate w3 blocks the circular rods in the moving plate w5. Under the elastic block of the limit block w1, the movement of the moving plate w5 can be fixed. And the heat at the bottom of the electronic instrument is dissipated from the gap between the moving plate w5 and the flat plate w2 towards the support block w4 direction, preventing the heat at the bottom of the electronic instrument from being not easily dissipated. Thus, it is convenient for the threaded installation of the electronic instrument on the pulled-out moving plate w5, avoiding the narrow space inside the box plate 43 and being not easy to perform manual threaded fixing and rotation operations.
[0022] The limit block w1 is provided with an arc plate w11, a spring w12, a connecting plate w13, and a concave plate w14. The arc plate w11 is fixedly embedded at the upper end of the connecting plate w13. The lower surface of the connecting plate w13 is attached to the upper end of the concave plate w14. The lower end of the connecting plate w13 is installed inside the middle of the concave plate w14. The upper end of the spring w12 is fixedly embedded at the lower end of the middle of the connecting plate w13. The concave plate w14 is fixedly embedded on the surface of the fixed plate w3. The moving plate w5 is in extrusion fit with the arc plate w11. The arc plate w11 is made of aluminum alloy and has the characteristics of strong toughness and easy deformation and bending. The connecting plate w13 is made of rubber and has the effect of being able to stretch and deform. Thus, when the circular rod at the lower end of the moving plate w5 moves, it laterally extrudes the surface of the arc plate w11, causing the arc plate w11 to bend downward. Then, under the compressive deformation of the connecting plate w13, the circular rod slides through the surface of the arc plate w11. When the moving plate w5 needs to be fixed, the spring w12 generates an upward elastic force under the support of the concave plate w14. Furthermore, the middle of the connecting plate w13 generates an upward stretch, causing the left and right ends of the arc plate w11 to generate an inward stretching deformation on the connecting plate w13. Then, the middle position of the arc plate w11 pops up upward, causing the arc plate w11 to be squeezed and fixed at the gap position between the circular rods, keeping the moving plate w5 in a moving and fixed state. Thus, when the electronic instrument is fixed by screw operation on the surface of the flat plate w2, it is more stable.
[0023] The heat dissipation mechanism 2 is provided with a gap plate 21, a flow channel 22, and an inclined plate 23. The flow channel 22 is located inside the inclined plate 23. The inclined plate 23 is installed on the left and right sides of the gap plate 21. The gap plate 21 is fixedly embedded inside the upper end of the box body 4. The inclined plate 23 has two that are distributed up and down at one gap position and are distributed in a state of tilting 25 degrees to the horizontal line to the left and right respectively. The inclined plates 23 on the left and right sides of the gap plate 21 are distributed in a high and low state. The flow channels 22 are distributed in a staggered state at the positions of the upper and lower two inclined plates 23. Thus, the splashed water flows from the side of the gap plate 21 to the position of the inclined plate 23 and is blocked on the inclined inclined plate 23. At the same time, the water enters the position of the lower inclined plate 23 after passing through the flow channel 22 in the upper inclined plate 23. Since the flow channels 22 are distributed in a staggered state at the upper and lower positions of the inclined plate 23, the water will be blocked at the inclined position of the lower inclined plate 23. Through the multiple blockages at the positions of the two inclined plates 23, the splashed water is prevented from flowing into the inside of the box plate 43.
[0024] The flat plate w2 is internally provided with hollow grooves that penetrate through the inside of the flat plate w2 and are arranged at intervals, having the effect of circulating air. Thus, after the electronic instrument is installed on the surface of the flat plate w2, heat can be dissipated through the hollow grooves at the bottom, avoiding the accumulation of heat that is not easily dissipated at the bottom of the electronic instrument.
[0025] Working principle: In this utility model, the fixing of the disassembly plate 42 is unscrewed by using a screwdriver tool. After opening the disassembly plate 42, the movable mechanism 41 is pulled out inside the box plate 43, and the electronic instrument is threadedly fixed on the surface of the movable mechanism 41. Then, the movable mechanism 41 is pushed into the box plate 43 to fix the electronic instrument. Moreover, the box body 4 connected to the support plate 3 is moved by holding the handle 1. Thus, after opening the disassembly plate 42, the right side of the movable plate w5 is manually pulled out, and the circular rod at the lower end of the movable plate w5 horizontally moves and slides out within the track. Consequently, the circular rod laterally squeezes and moves the arc-shaped plate w11 in the limit block w1 on the surface of the fixed plate w3, causing the arc-shaped plate w11 to bend downward. Then, under the compressive deformation of the connecting plate w13, the circular rod slides through the surface of the arc-shaped plate w11. After the movable plate w5 is translated, the limit block w1 on the right side of the fixed plate w3 blocks the circular rod in the movable plate w5, stopping the movement when the movable plate w5 needs to be fixed. The spring w12 generates an upward elastic force under the support of the concave plate w14. Then, the middle of the connecting plate w13 is stretched upward, causing the left and right ends of the arc-shaped plate w11 to generate an inward tensile deformation on the connecting plate w13. Subsequently, the middle position of the arc-shaped plate w11 pops up upward, causing the arc-shaped plate w11 to be squeezed and fixed at the gap position between the circular rods, keeping the movable plate w5 in a fixed state of movement. Therefore, when the electronic instrument is threadedly operated and fixed on the surface of the flat plate w2, it is more stable, facilitating the manual threaded installation of the electronic instrument on the pulled-out movable plate w5 and avoiding the narrow space inside the box plate 43, which is not conducive to manual threaded fixing and rotation operations.
[0026] In this utility model, since the box body 4 is in a semi-sealed state as a whole, only the heat dissipation mechanism 2 is in communication with the outside air. Thus, the splashed water enters the gap of the gap plate 21 from above. The water flows toward the inclined plate 23 on the side of the gap plate 21 and is blocked on the inclined inclined plate 23. At the same time, the water enters the lower inclined plate 23 after passing through the flow-through groove 22 in the upper inclined plate 23. Since the flow-through grooves 22 are staggeredly distributed at the upper and lower positions of the inclined plate 23, the water will be blocked at the inclined position of the lower inclined plate 23. And the staggeredly distributed flow-through grooves 22 do not affect the outward dissipation of heat. With the heat in the box plate 43 dissipating upward, the water at the inclined plate 23 position will be slowly heated and dissipated upward. Therefore, through the multiple staggered blockages at the positions of the two inclined plates 23, the splashed water is prevented from flowing into the box plate 43.
