In addition, unless otherwise specified, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated.

[0030] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0031] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] In the description of this specification, the description with reference to the terms "one embodiment", "some optional implementations" or "some optional embodiments" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0033] The current data acquisition device usually includes a housing and an acquisition mainboard, which is arranged inside the housing. When in use, there is no design prompt component to prompt the user whether it is in a normal operating state, which makes it difficult for the user to quickly determine whether the data acquisition device is operating normally. Sometimes a damaged data acquisition device is plugged into the device and the user still thinks that the data acquisition device is operating normally, which wastes time. However, the present application prompts the user of the operating status of the data acquisition device by adding a light source module, thereby facilitating the user to identify whether the data acquisition device is in a normal operating state for easy use.

[0034] Please also see Figure 1 and Figure 2 An embodiment of the utility model provides a data acquisition device, including: a front cover 10, a rear shell 20 and an acquisition mainboard 30.

[0035] See also Figure 3The front cover 10 is detachably disposed on the rear shell 20, and is surrounded by the rear shell 20 to form a sealed cavity 40. A through groove 11 is disposed on the front cover 10, and the through groove 11 is communicated with the sealed cavity 40; a lamp hole 21 and a light guide column 22 are disposed on the rear shell 20, and the lamp hole 21 is communicated with the sealed cavity 40. The light guide column 22 is disposed in the lamp hole 21 and seals the lamp hole 21. The light guide column 22 prevents liquid from entering the sealed cavity 40 from the lamp hole 21. The light guide column 22 can also play a role in guiding light, guiding the light in the sealed cavity 40 to be emitted out of the sealed cavity 40.

[0036] The acquisition main board 30 is arranged in the sealed cavity 40, and a connector 31 and a light source module 32 are arranged on the acquisition main board 30. The connector 31 passes through the through slot 11 and then extends out of the sealed cavity 40. The position of the light source module 32 corresponds to the position of the lamp hole 21. The light emitted by the light source module 32 enters the lamp hole 21, and is guided by the light guide column 22 and then emitted to the outside of the sealed cavity 40, so as to facilitate user observation.

[0037] The specific structure of the light source module 32 can be designed according to actual needs. For example, the light source module 32 includes LED lamp beads, which are arranged on the acquisition mainboard 30 and electrically connected to the acquisition mainboard 30. The light source module 32 corresponds to the position of the lamp hole 21. For example, the light emission direction of the light source module 32 is designed to be toward the lamp hole 21, or the light source module 32 is arranged near the opening of the lamp hole 21, so that the light emitted by the light source module 32 can enter the lamp hole 21.

[0038] The acquisition mainboard 30 can realize signal connection with the device through the connector 31. It should be noted that the light source module 32 can emit different light in different operating states of the acquisition mainboard 30. For example, when the acquisition mainboard 30 is operating normally, the light source module 32 can emit green light, and when the acquisition mainboard 30 is not operating normally, the light source module 32 can emit red light, so as to facilitate user judgment. In addition, after the connector 31 is connected to the device, if the light source module 32 does not emit light, it may be that the connector 31 is damaged or the circuit on the acquisition mainboard 30 is broken, etc., and it can also be judged that the data acquisition module is abnormal and needs to be repaired.

[0039] The detachable design of the front cover 10 and the rear shell 20 is intended to facilitate production and installation, as well as to remove the acquisition mainboard 30 for inspection and replacement during subsequent maintenance.

[0040] See also Figure 4In some optional embodiments, a limiting step 211 is provided in the lamp hole 21, and a first limiting protrusion 221 and a second limiting protrusion 222 are provided on the side of the light guide column 22. The second limiting protrusion 222 and the first limiting protrusion 221 are located on both sides of the limiting step 211 to cooperate in limiting the position of the light guide column 22. In this embodiment, when the light guide column 22 is installed, the light guide column 22 is inserted into the lamp hole 21 from the outside of the sealed cavity 40, so that the second limiting protrusion 222 passes over the limiting step 211 and then extends into the sealed cavity 40. The limiting step 211 is located between the second limiting protrusion 222 and the first limiting protrusion 221. The limiting step 211 is blocked by the limiting step 211, so that the light guide column 22 cannot move along the lamp hole 21, thereby realizing the position limitation of the light guide column 22, and the structure is stable and easy to install. In addition, in this embodiment, in order to facilitate the second limiting protrusion 222 to cross the limiting step 211, the end of the light guide column 22 adopts a conical design, so that the light guide column 22 can smoothly squeeze the limiting step 211 and drive the rear shell 20 structure near the limiting step 211 to deform, and then the second limiting protrusion 222 crosses the limiting step 211.

[0041] In some optional embodiments, a first sealing ring 212 is provided in the lamp hole 21. The first sealing ring 212 is arranged around the light guide column 22. The first sealing ring 212 is in the gap between the lamp hole 21 and the light guide column 22, which is beneficial to improve the sealing of the lamp hole 21, prevent liquid, dust, etc. from entering the sealed cavity 40, and protect the acquisition mainboard 30.

[0042] The material of the first sealing ring 212 can be designed according to actual needs. For example, the first sealing ring 212 can be a rubber ring or a silicone ring.

[0043] In order to facilitate the installation and fixation of the first sealing ring 212, in some optional embodiments, a first sealing ring 212 is further provided in the lamp hole 21, and the first sealing ring 212 is located between the limiting step 211 and the first limiting protrusion 221. The first sealing ring 212 and the limiting step 211 are both arranged around the light guide column 22, and the first limiting protrusion 221 presses the first sealing ring 212 toward the limiting step 211, so that the first sealing ring 212 is limited between the first limiting protrusion 221 and the limiting step 211, and cannot move along the lamp hole 21. Moreover, since the first limiting protrusion 221 can press the first sealing ring 212, the first sealing ring 212 can produce elastic deformation, which is conducive to improving the sealing effect of the first sealing ring 212. In addition, the limiting step 211 makes the extension path of the gap between the inner wall of the lamp hole 21 and the light guide column 22 bend, which increases the difficulty of liquid and dust entering the sealing cavity 40, which is conducive to improving the waterproof sealing effect.

[0044] See also Figure 5In some optional embodiments, a second sealing ring 12 is disposed on the outside of the front cover 10 and surrounds the front cover 10, at least a portion of the front cover 10 extends into the rear shell 20, and the second sealing ring 12 is located between the outer side of the front cover 10 and the inner side of the rear shell 20. The second sealing ring 12 helps prevent liquid, dust, etc. from entering the sealed cavity 40 through the gap between the front cover 10 and the rear shell 20, and helps protect the acquisition mainboard 30.

[0045] The material of the second sealing ring 12 can be designed according to actual needs. For example, the second sealing ring 12 can be a rubber ring or a silicone ring.

[0046] To facilitate the installation of the second sealing ring 12, in some optional embodiments, a positioning groove 13 is provided on the outer side of the front cover 10, and the second sealing ring 12 is arranged in the positioning groove 13 to avoid the second sealing ring 12 being driven by the friction force and shifting its position when the front cover 10 is inserted into the rear shell 20 due to friction between the second sealing ring 12 sleeved on the outer side of the front cover 10 and the rear shell 20, thereby effectively improving the position stability of the second sealing ring 12.

[0047] The detachable connection mode of the front cover 10 and the rear shell 20 can be designed according to actual needs. For example, in some optional embodiments, elastic ear buckles 14 are respectively provided on both sides of the front cover 10; ear buckle grooves 23 are respectively provided on both sides of the rear shell 20, and the ear buckle grooves 23 are communicated with the sealing cavity 40. The ear buckle grooves 23 are buckled with the elastic ear buckles 14 so that the front cover 10 can be detachably mounted on the rear shell 20. When the front cover 10 needs to be removed, it is only necessary to press the elastic ear buckle 14 from the outside of the rear shell 20 to disengage the elastic ear buckle 14 from the ear buckle grooves 23, and then the front cover 10 can be pulled out from the rear shell 20. The structure is simple and the disassembly and assembly are convenient.

[0048] Of course, the detachable connection method of the front cover 10 and the rear shell 20 is not limited to this, and those skilled in the art may also select other suitable structures according to the teachings of the present invention. For example, a plurality of buckle grooves are provided on the side of the front cover 10, and a plurality of protruding buckles are provided on the rear shell 20, and the buckles correspond to and detachably cooperate with the buckle grooves to make the front cover 10 and the rear shell 20 detachably connected; or, the front cover 10 and the rear shell 20 are detachably connected by a plurality of screws.

[0049] See also Figure 5 In some optional embodiments, two first board edge positioning grooves 15 are provided on the front cover 10, and the two first board edge positioning grooves 15 are located on both sides of the sealed cavity 40. The acquisition main board 30 is positioned and matched with the first board edge positioning grooves 15, thereby preventing the acquisition main board 30 from shaking in the sealed cavity 40 and improving the position stability of the acquisition main board 30.

[0050] See also Figure 6In some optional embodiments, a second board edge positioning groove 24 is provided on the rear shell 20, and the second board edge positioning groove 24 is located on the side of the sealed cavity 40 away from the through groove 11. The acquisition mainboard 30 is positioned and matched with the second board edge positioning groove 24, thereby preventing the acquisition mainboard 30 from shaking in the sealed cavity 40, and improving the position stability of the acquisition mainboard 30. In addition, since the second board edge positioning groove 24 is located on the side of the sealed cavity 40 away from the through groove 11, when the acquisition mainboard 30 is installed, the connector 31 extends into the through groove 11, so that one side of the acquisition mainboard 30 is initially positioned, and the second board edge positioning groove 24 can position the other side of the acquisition mainboard 30, thereby cooperating with the through groove 11 to achieve the positioning of the acquisition mainboard 30, and improving the position stability of the acquisition mainboard 30.

[0051] In the present embodiment, the through slot 11 and the second board edge positioning slot 24 are located on two opposite sides of the acquisition main board 30, and the two first board edge positioning slots 15 are respectively located on the other opposite sides of the acquisition main board 30, which is equivalent to that the front, back, left and right sides of the acquisition main board 30 are all stably positioned, so that the position of the acquisition main board 30 is accurately positioned, the position is relatively stable, and it is difficult to shake.

[0052] See also Figure 7 In some optional embodiments, a boss 16 and a connecting ring 17 are provided on the front cover 10, the through groove 11 is located at the top of the boss 16, an elastic pad 18 is provided on the boss 16, an elastic pad 18 is provided at the top of the boss 16, a through hole 181 is provided on the elastic pad 18, the through hole 181 is communicated with the through groove 11, the connecting ring 17 is sleeved on the boss 16, the connector 31 passes through the through groove 11 and the through hole 181 in sequence, and then extends to the outside of the sealed cavity 40. When the connector 31 is connected to the device, the connecting ring 17 is used to engage with the structure on the device to achieve fixation, thereby preventing the front cover 10 from shaking relative to the device, thereby protecting the connector 31. In addition, when the connecting ring 17 is connected to the device, the boss 16 abuts against the structure of the device through the elastic pad 18, which can provide a buffering effect, thereby avoiding the possibility of a gap or mutual extrusion between the top of the boss 16 and the surface of the device, and can also improve the sealing between the device and the boss 16, preventing liquid, dust, etc. from passing through the gap between the device and the boss 16 and then contacting the connector 31, or entering the sealing cavity 40 through the gap between the through groove 11 and the connector 31.

[0053] The specific structure of the connecting ring 17 can be designed according to actual needs. For example, in this embodiment, a plurality of first protrusions 171 and a plurality of second protrusions 172 are provided in the connecting ring 17. The first protrusions 171 are engaged with the structure of the device, thereby achieving the fixation of the connecting ring 17 and the device. An annular slide groove 161 is provided on the side of the boss 16, and the second protrusions 172 extend into the slide groove 161, so that the connecting ring 17 is restricted on the boss 16 and can rotate along the slide groove 161 relative to the boss 16, which is convenient for adjusting the position of the first protrusion 171, and then facilitating the engagement of the first protrusion 171 with the device.
