Description

Technical Field

[0001] This utility model belongs to the field of industrial testing technology, specifically relating to a modular and detachable signal acquisition device. Background Technology

[0002] Modular and detachable signal acquisition devices are flexible devices designed to efficiently and accurately acquire various signals, and allow users to easily replace modules and upgrade the system according to different needs. They break through the limitations of the fixed structure of traditional signal acquisition devices, achieving customization and scalability by encapsulating different functions into independent modules.

[0003] However, when the signal collector is dissipating heat, its internal ventilation holes lack a dust interception process, causing dust to accumulate inside the device and in the ventilation holes, requiring frequent cleaning of the ventilation holes. Utility Model Content

[0004] The purpose of this invention is to provide a modular and detachable signal acquisition device to solve the problem mentioned in the background art that the internal ventilation holes of the signal acquisition device lack a dust interception process when dissipating heat.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modular and detachable signal acquisition device, comprising a housing and a main body of the device installed inside the housing; A front cover is fixedly connected to the front outer wall of the main body of the device; Multiple ventilation holes are provided inside the outer walls at both ends of the outer casing; The front outer wall of the front cover is provided with a display screen, and a wire box is fixedly connected to the front outer wall of the front cover near the left side. Multiple line interfaces are opened inside the left outer wall of the wire box, and multiple operation buttons are provided on the lower side of the display screen. Dustproof nets are provided on the inner walls of both the left and right ends of the outer casing.

[0006] Preferably, the inner walls of the left and right ends of the outer shell and the front and rear sides of the dustproof net are provided with limit strips, and a fixing rod passing through the dustproof net is provided between the two limit strips to limit the position of the center of the dustproof net when it rotates.

[0007] Preferably, magnetic strips are provided inside one end of both limiting strips and dustproof nets to magnetically fix them to the outer shell.

[0008] Preferably, the lower outer wall of both dustproof nets is arc-shaped on the side near the inner wall of the outer shell, and the interior of both dustproof nets is provided with grooves for the fitting of the limiting strip.

[0009] Preferably, the inner walls of both the left and right ends of the outer casing are embedded with magnetic plates for magnetic strips to be attracted.

[0010] Preferably, the outer wall of the right end of the housing is fixedly connected to handles near the front and rear sides, so as to drive the device to move under the action of external force.

[0011] Preferably, the front outer wall of the front cover has a sound-emitting hole.

[0012] Preferably, threaded holes with forward openings are provided at the four corners of the front outer wall of the outer shell, and fastening screws are provided at the four corners of the front outer wall of the front cover to engage with the threaded holes and restrict the position between the outer shell and the front cover.

[0013] Preferably, a limiting frame is fixedly connected to the rear outer wall of the front cover to guide the contact between the front cover and the outer shell.

[0014] Preferably, the lower outer wall of the outer casing is fixedly connected to four corners with feet.

[0015] Compared with the prior art, this utility model provides a modular and detachable signal acquisition device, which has the following advantages: By installing a dust filter, dust in the air can be intercepted when the main body of the equipment dissipates heat through the ventilation holes. This greatly reduces the possibility of dust entering the equipment, thereby avoiding short circuit faults caused by dust accumulation and ensuring the stable operation of the signal acquisition device.

[0016] By installing limit strips and fixing rods, when removing the dust screen for cleaning, the dust screen is first tilted under the restriction of the fixing rods. At this time, the unstable dust will fall and be intercepted by the limit strips. When the dust screen is removed later, it can prevent the dust from falling into the inside of the shell, greatly reducing the spread of dust in the environment around the equipment during the cleaning process and optimizing the cleaning process.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figure 1-5 The modular and detachable signal acquisition device shown includes a housing 1 and a device body 5 installed inside the housing 1. A front cover 7 is fixedly connected to the front outer wall of the main body 5 of the equipment; Multiple ventilation holes 3 are provided on the inner walls of both the left and right ends of the outer casing 1; A display screen 11 is provided on the front outer wall of the front cover 7. A junction box 12 is fixedly connected to the front outer wall of the front cover 7 near the left side. Multiple line interfaces 14 are opened inside the left outer wall of the junction box 12. Multiple operation buttons 10 are provided on the lower side of the display screen 11. The parameters of the signal acquisition device are set by the operation buttons 10. The multiple line interfaces 14 on the junction box 12 facilitate the connection of external devices to obtain signal sources. External signals are connected to the signal acquisition device through the line interfaces 14. Digital signals directly enter the digital acquisition module inside the device body 5. This module decodes and processes the signals according to different digital communication protocols. The acquired digital signals are transmitted to the processing module. The processed signal data can be stored in the storage module inside the device body 5. The processed data can also be displayed on the display screen 11 for users to view, or transmitted to external devices through the line interfaces 14 for further analysis and processing. The device body 5 generates heat during operation, which is exchanged through the ventilation holes 3. Dustproof nets 13 are provided on the inner walls of both the left and right ends of the outer casing 1. The dustproof nets 13 are installed inside the ventilation holes 3. When air enters or exits the ventilation holes 3, the dustproof nets 13 intercept dust particles in the air, prevent dust from entering the equipment, protect the electronic components inside the main body 5 from dust contamination, and reduce the risk of failure caused by dust accumulation.

[0025] like Figure 4 and Figure 5 As shown, limit strips 17 are provided on the inner walls of the left and right ends of the outer shell 1 and on the front and rear sides of the dustproof net 13. A fixing rod 18 passing through the dustproof net 13 is provided between the two limit strips 17 to limit the position of the center of the dustproof net 13 when it rotates. Magnetic strips 16 are provided inside the two limit strips 17 and one end of the dustproof net 13 to be magnetically fixed to the outer shell 1. The lower outer walls of the two dustproof nets 13 are arc-shaped on the side close to the inner wall of the outer shell 1. The interior of the two dustproof nets 13 is provided with grooves for the limit strips 17 to fit into.

[0026] Gently hold the dustproof net 13 and tilt it to one side using the fixed rod 18 as the axis. Due to the arc-shaped design of the lower outer wall of the dustproof net 13, the tilting operation is relatively smooth. After tilting to the correct position, it will abut against the limiting strip 17. As the dustproof net 13 tilts, the unstable dust attached to it will begin to fall under the action of gravity. The falling dust is intercepted by the limiting strips 17 on the front and rear sides, preventing the dust from falling into the inside of the equipment shell 1. Then pull the dustproof net 13 outward and clean it. After cleaning, align the dustproof net 13 with the installation position on the shell 1, and the magnetic strip 16 and the shell 1 will be magnetically attracted and fixed.

[0027] like Figure 4 and Figure 5 As shown, magnetic plates for magnetic strips 16 to be attracted are embedded in the inner walls of both the left and right ends of the outer casing 1.

[0028] The magnetic field generated by the magnetic strip 16 attracts the magnetic plate, providing sufficient fixing force to keep the dustproof net 13 in a stable position during normal operation of the equipment.

[0029] like Figure 1 As shown, handles 2 are fixedly connected to the outer wall of the right end of the outer casing 1 and near the front and rear sides respectively, so as to drive the device to move under the action of external force.

[0030] When it is necessary to move the signal acquisition device, the operator applies external force by gripping handle 2, using the strength of the human arm to move the entire device.

[0031] like Figure 1 As shown, a sound-emitting hole 9 is provided on the outer wall of the front end of the front cover 7.

[0032] When the equipment is in a specific state, the sound-emitting device generates sound, which is transmitted to the outside through the sound-emitting hole 9, allowing the operator to perceive the equipment status in a timely manner.

[0033] like Figure 1As shown, threaded holes 4 with forward openings are provided at the four corners of the front outer wall of the outer shell 1, and fastening screws 8 are provided at the four corners of the front outer wall of the front cover 7 to be screwed together with the threaded holes 4 to restrict the position between the outer shell 1 and the front cover 7. A limit frame 6 is fixedly connected to the rear outer wall of the front cover 7 to guide the front cover 7 and the outer shell 1 to abut against each other.

[0034] By rotating the fastening screw 8, it is screwed into the threaded hole 4. As the screw is tightened, the distance between the front cover 7 and the outer shell 1 gradually decreases and eventually fits tightly. When the front cover 7 is installed, the limiting frame 6 can be accurately inserted into the front end of the outer shell 1, guiding the front cover 7 to align with the outer shell 1.

[0035] like Figure 2 As shown, support legs 15 are fixedly connected to the four corners of the lower outer wall of the outer casing 1.

[0036] The support feet 15 keep the equipment at a certain distance from the surface on which it is placed, preventing the equipment from directly contacting the surface and preventing damage to the equipment due to factors such as dampness or unevenness of the surface.

[0037] The implementation principle of this embodiment is as follows: the parameters of the signal acquisition device are set by operating button 10. Multiple line interfaces 14 on the junction box 12 facilitate the connection of external devices to obtain signal sources. External signals are connected to the signal acquisition device through line interfaces 14. Digital signals directly enter the digital acquisition module inside the device body 5. This module decodes and processes the signals according to different digital communication protocols. The acquired digital signals are transmitted to the processing module. The processed signal data can be stored in the storage module inside the device body 5. The processed data can also be displayed on the display screen 11 for users to view, or transmitted to external devices through line interfaces 14 for further analysis and processing. The device body 5 generates heat during operation, which is exchanged through the ventilation holes 3. The dustproof net 13 is installed inside the ventilation holes 3. When air enters and exits the ventilation holes 3, the dustproof net 13 intercepts dust particles in the air, preventing dust from entering the device and protecting the electronic components inside the device body 5 from dust contamination, reducing the risk of failure caused by dust accumulation.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
