[0003] Current data acquisition devices often connect the two housings of the device with screws. This method requires frequent tightening and alignment of screws when repairing the components inside the data acquisition device, which affects the maintenance of the components inside the data acquisition device. Utility Model Content

[0004] This utility model mainly provides a data acquisition device to solve the technical problems mentioned in the background art.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A data acquisition device includes a first housing and a second housing connected to each other, and the first housing and the second housing are connected by a locking mechanism;

[0007] The locking mechanism includes protrusions connected to the lower surface of the second housing. The protrusions are symmetrically arranged, and a permanent magnet is connected to one side of each of the two protrusions that are far apart from each other.

[0008] A metal strip is connected to the inner wall surface of the first housing, and the metal strip is magnetically connected to a permanent magnet.

[0009] Furthermore, the upper surface of the first housing is provided with a protruding edge along the inner wall of the housing, and the protruding edge fits into the inner cavity of the second housing.

[0010] Furthermore, the convex edge is provided with a plurality of through holes along its inner wall, and a locking tongue is connected inside the hole of each through hole.

[0011] Furthermore, the latch is a sheet, and the sheet of the latch is provided with a protrusion and a compression part from top to bottom.

[0012] Furthermore, the inner surface of the second housing is provided with a groove, the groove of which is used for the locking tongue to engage.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] This application provides a data acquisition device, as shown in the schematic diagram below. Figure 1-4 As shown. The data acquisition device includes a first housing 1 and a second housing 2 connected to each other, and the first housing 1 and the second housing 2 are connected by a locking mechanism 3;

[0027] The locking mechanism 3 includes a protrusion 31 connected to the lower surface of the second housing 2. The protrusions 31 are symmetrically arranged, and a permanent magnet 32 ​​is connected to one side of the two protrusions 31 that are far apart from each other.

[0028] A metal strip 12 is connected to the inner wall surface of the first housing 1, and the metal strip 12 is magnetically connected to the permanent magnet 32.

[0029] Optional, such as Figure 1 and Figure 3 As shown, the upper surface of the first housing 1 is provided with a protruding edge 11 along the inner wall of the housing, and the protruding edge 11 fits into the inner cavity of the second housing 2.

[0030] In this embodiment, the protruding edge 11 is provided to guide the second housing 2 to be accurately aligned with the first housing 1. This allows the second housing 2 to be inserted into the first housing 1 along the protruding edge 11, thus completing the connection between the second housing 2 and the first housing 1.

[0031] Optional, such as Figure 1 and Figure 3 As shown, the protruding edge 11 is provided with a plurality of through holes 111 arranged along its inner wall, and a locking tongue 112 is connected inside the hole of the through hole 111.

[0032] In this embodiment, the latch 112 is accommodated through the through hole 111, allowing the latch 112 to move.

[0033] Optional, such as Figure 1 and Figure 3 As shown, the latch 112 is a sheet, and the sheet of the latch 112 is provided with a protrusion 113 and a compression portion 114 from top to bottom.

[0034] The inner surface of the second housing 2 is provided with a groove 21, and the groove of the groove 21 is used for the locking tongue 112 to be engaged.

[0035] In this embodiment, when the second housing 2 is inserted into the first housing 1 along the protruding edge 11, the protrusion 113 on the locking tongue 112 is squeezed into the groove 21, thereby increasing the resistance when the second housing 2 is separated from the first housing 1. When separating the second housing 2 from the first housing 1, it is only necessary to apply force to the two housings in a direction away from each other, so that the protrusion 113 on the locking tongue 112 can be disengaged from the groove 21, thereby quickly completing the separation of the housing of the acquisition device, which facilitates the maintenance of the components inside the device.
