[0002] Data acquisition refers to the automatic collection of analog or digital signals from the device being measured and sending them to the host computer for analysis and processing. A data acquisition card is a computer expansion card that implements data acquisition functions.

[0003] Existing data acquisition cards are rectangular, sheet-like structures. Their mounting structure includes a mounting plate, which is fixed to the sidewalls of the mounting plate with screws. A plug-in plate is integrally fixed to one end of the mounting plate, and a fixed plate is welded to the other end. The fixed plate is perpendicular to the length of the mounting plate, and mounting holes are provided through the sidewalls of the fixed plate. During data acquisition card installation, workers pre-install the plug-in plate into the socket of the data device. Bolts are inserted into the mounting holes to secure the fixed plate to the data device, defining the positions of the fixed plate and the plug-in plate, thereby securing the data acquisition card.

[0004] In the process of fixing the data information card in the above manner, the staff illuminates the interior of the data device with a flashlight, and then fixes the data acquisition card in the data device in the above manner. This fixing method requires the cooperation of multiple staff members, and there is a problem of inconvenient installation of the data acquisition card, which needs to be improved. Summary of the Invention

[0005] In order to reduce the labor consumption when installing a data acquisition card and improve the convenience of installing a data acquisition card, the present application provides a data acquisition card that is easy to install.

[0006] This application provides a data acquisition card that is easy to install and adopts the following technical solution:

[0007] A data acquisition card that is easy to install comprises a mounting plate and a rotating disk rotatably connected to the mounting plate, a jump piece is rotatably connected to the rotating disk, a traction belt is fixed to the outer wall of the rotating disk, a limit block for limiting the rotation of the jump piece is provided on the outer wall of the rotating disk, a light strip is installed on the outer wall of the data acquisition card, the jump piece is electrically connected to the light strip, a conductive seat is fixed on the mounting plate, the jump piece can abut against the side wall of the conductive seat, a fixed baffle is slidably connected to the mounting plate, the data acquisition card is fixed to the side wall of the fixed baffle, the end of the traction belt is provided with a connecting component for connecting to the fixed baffle, and a limit assembly for limiting the sliding of the fixed baffle is provided on the mounting plate.

[0008] By adopting the above technical solution, the data acquisition card is fixed to the side wall of the fixed baffle by screws. When the data acquisition card is installed on the data device, the end of the fixed baffle is connected to the end of the traction belt by the connecting component in advance, and the fixed baffle slides on the mounting plate, driving the traction belt to move. The traction belt pulls the rotating disk to rotate, driving the overlapping piece to rotate, so that the overlapping piece abuts against the side wall of the conductive seat, so that the light strip is energized and the light strip is illuminated. Under the illumination of the light strip, the mounting plate is fixed to the data device, and the fixed baffle is continued to be manually driven to slide. The limit block limits the rotation of the overlapping piece, so that the overlapping piece is separated from the conductive seat, and the light strip is powered off. At this time, the limit component limits the sliding of the fixed baffle, thereby achieving the fixation of the data acquisition card; when the fixed baffle needs to be removed separately, the fixed baffle is manually driven to slide, driving the rotating disk to rotate, the overlapping piece contacts the side wall of the conductive seat again, the light strip is illuminated, and the fixed baffle is removed from the mounting plate. The light strip is turned on by installing and removing the data acquisition card. Under the illumination of the light strip, it is convenient for the staff to install the data acquisition card, which reduces the use of manpower and brings convenience to the staff.

[0009] Optionally, the jumper piece can slide on the rotating disk, a first support block and a second support block are fixed on the side wall of the conductive seat, and a first elastic member is provided on the mounting plate to return the jumper piece to its original position.

[0010] By adopting the above technical solution, when the staff removes the data acquisition card, the jumper contacts the first support block, and then rotates the jumper to between the first support block and the second support block and abuts the side wall of the conductive seat, at which time the light strip is energized; when the staff installs the data acquisition card, the jumper passes through the second support block, and then rotates between the first support block and the second support block, and the light strip is energized and illuminated. When the jumper passes through the first support block and the second support block, the first elastic member stretches under the support of the first support block and the second support block, and after the jumper passes through the first support block and the second support block, the side wall of the jumper contacts the side wall of the conductive seat under the action of the self-rebound force of the first elastic member, thereby energizing the light strip; the setting of the first support block and the second support block plays a limiting role on the one hand, reducing the possibility of the jumper rotating away from the conductive seat on its own, and on the other hand, has the function of blocking the jumper, reducing the possibility of the jumper contacting the conductive seat at any time, thereby reducing the waste of electricity.

[0011] Optionally, the limiting assembly includes a clamping block fixed on the side wall of the fixed baffle and a limiting plate fixed on the clamping block, and a clamping groove formed between the clamping block and the limiting plate is clamped to the mounting hole on the inner wall of the data device.

[0012] By adopting the above technical solution, the staff drives the fixed baffle to slide, so that the clamping block and the limiting plate move to a position close to the mounting hole on the data device. At this time, the limiting plate is inserted into the mounting hole. Under the clamping limit of the clamping block and the limiting plate, the sliding of the fixed baffle is restricted.

[0013] Optionally, the connecting component includes a pressing plate hinged on one end of the fixed baffle away from the clamping block and a locking block fixed on the side wall of the pressing plate, the traction belt is located between the clamping block and the locking block, and the side wall of the locking block is squeezed against the outer wall of the traction belt.

[0014] By adopting the above technical solution, the staff inserts the end of the traction belt between the pressing plate and the outer wall of the fixed baffle, pulls the pressing plate, and buckles the pressing plate onto the outer wall of the fixed baffle. Under the pressure of the pressing plate, there is extrusion between the locking block and the outer wall of the traction belt, and the locking block abuts against the outer wall of the traction belt, thereby realizing the connection between the fixed baffle and the traction belt.

[0015] Optionally, a plurality of protrusions are fixed on the side wall of the locking block, and the ends of the protrusions facing away from the locking block are all pointed, and the ends of the protrusions are embedded in the outer wall of the traction belt.

[0016] By adopting the above technical solution, when the staff pulls the pressing plate to connect the fixed baffle and the traction belt, the locking block drives the protrusion to move, so that the tip of the protrusion is inserted into the traction belt, thereby making the connection between the fixed baffle and the traction belt more stable.

[0017] Optionally, a second elastic member for returning the fixed baffle to its original position is provided on the mounting plate, one end of the second elastic member is fixedly connected to the side wall of the mounting plate, and the other end is fixedly connected to the outer wall of the fixed baffle.

[0018] By adopting the above technical solution, the staff needs to drive the fixed baffle to slide away from the traction belt during the installation process of the fixed baffle. During the sliding process of the fixed baffle, the second elastic member extends. After the fixed baffle is clamped on the inner wall of the data device, the second elastic member applies a force toward the traction belt under the action of its own rebound force, thereby reducing the possibility of the fixed baffle being separated from the traction belt.

[0019] Optionally, a switch is provided on the outer wall of the data acquisition card, a battery box is installed on the outer wall of the data acquisition card, the switch is electrically connected to the light strip, the battery box is electrically connected to the switch, and the battery box is electrically connected to the light strip.

[0020] By adopting the above technical solution, the staff loads batteries into the battery box. When it is necessary to install or remove the fixed baffle, the staff presses the switch in advance to power on the light strip. The staff does not need to use a flashlight separately, which makes it convenient for the staff to install and remove the fixed baffle.

[0021] Optionally, a guide rod is fixed on the side wall of the mounting plate, a sliding groove is provided on the side wall of the guide rod, a fixed baffle is slidingly connected to the inner wall of the sliding groove, a clamping groove is provided on the outer wall of the guide rod, a positioning block is clamped and fixed on the inner wall of the clamping groove, the fixed baffle and the side wall of the positioning block are slidingly arranged, and the clamping groove is opened at an angle.

[0022] By adopting the above technical solution, the setting of the guide rod guides the sliding of the fixed baffle, making the sliding of the fixed baffle smoother. When the staff pulls the fixed baffle, the fixed baffle slides in the sliding groove. When the fixed baffle needs to be removed separately, first drive the fixed baffle away from the positioning block, take the positioning block out of the snap-fit ​​groove, and then take the fixed baffle out of the snap-fit ​​groove.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Pre-connect the fixed baffle and the traction belt through the connecting parts, manually drive the fixed baffle to slide, the fixed baffle drives the traction belt to move, drives the rotating disk to rotate, and the overlapping piece rotates under the obstruction of the limit block. When the overlapping piece rotates to the outside of the conductive seat, the overlapping piece abuts against the side wall of the conductive seat. At this time, the light strip is energized and illuminated. The limit assembly limits the sliding of the fixed baffle, and the inner wall of the data equipment is illuminated by the lighting of the light strip, which is convenient for the staff to install the data collection card.

[0025] 2. A clamping block is welded and fixed to the end of the fixed baffle, and a limiting piece is welded and fixed to the side of the clamping block away from the fixed baffle. During the installation of the data acquisition card, the staff inserts one end of the fixed baffle into the hole on the inner wall of the data device, and inserts the limiting piece into the installation hole on the inner wall of the data device. Under the restriction of the clamping block and the limiting piece, the fixed baffle is fixed, thereby fixing the data acquisition card. No screws are required, making the fixation of the data acquisition card simpler. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Embodiment 2;

[0039] The difference between the second embodiment and the first embodiment is that: Figure 2 and Figure 3 The data acquisition card for easy installation also includes a mounting plate 1 and a guide rod 20 fixed to the mounting plate 1 by screws. The cross-section of the guide rod 20 is long. The guide rod 20 is arranged along the length direction of the mounting plate 1. A sliding groove 21 is opened on the side of the guide rod 20 away from the mounting plate 1. A sliding rod 31 is slidably connected to the inner wall of the sliding groove 21. The fixed baffle 7 is fixed to the outer wall of the sliding rod 31 by screws. When the staff pulls the sliding rod 31 to move, the sliding rod 31 slides in the sliding groove 21.

[0040] Reference Figure 3The guide rod 20 has a sidewall with a snap-fitting groove 22. In this application, two snap-fitting grooves 22 are preferably provided. The two snap-fitting grooves 22 are symmetrically arranged along the centerline of the length of the guide rod 20. The snap-fitting grooves 22 are wedge-shaped, and the cross-sectional area of ​​the snap-fitting groove 22 on the side close to the mounting plate 1 is smaller than the cross-sectional area of ​​the snap-fitting groove 22 on the side away from the mounting plate 1. A positioning block 23 is fixedly secured in each snap-fitting groove 22. The staff removes the positioning block 23 from the snap-fitting groove 22 and inserts the sliding rod 31 into the sliding groove 21. The snap-fitting groove 22 guides the sliding movement of the sliding rod 31, thereby facilitating the installation of the sliding rod 31. After the sliding rod 31 is installed in the sliding groove 21, a groove of the same shape as the sliding groove 21 is also formed on the sidewall of the positioning block 23. The sliding rod 31 slides in the sliding groove 21 on the positioning block 23, thereby limiting the position of the sliding rod 31.

[0041] Reference Figure 3 A second elastic member 18 is provided on the inner wall of the sliding groove 21 to enable the sliding rod 31 to return to its original position. In this application, a spring is preferably used as the second driving member; a circular hole is provided on the side wall of the sliding rod 31, one end of the second driving member is welded and fixed to the inner wall of the sliding rod 31, and the other end is hung in the circular hole. When the sliding rod 31 slides in the sliding groove 21, the second elastic member 18 is extended or compressed. Under the action of the self-rebound force of the second elastic member 18, the sliding rod 31 slides to its initial position, and the setting of the second elastic member 18 plays a traction role.

[0042] Reference Figure 3 and Figure 4 A groove 24 is formed on the side wall of the mounting plate 1. A support 26 is fixed to the bottom wall of the groove 24 via screws. The rotating disk 2 is rotatably connected to the support 26. The traction belt 4 is fixed to the outer wall of the rotating disk 2 via rivets. One end of the traction belt 4 is fixed to the outer wall of the rotating disk 2. A connecting member 8 for connecting the fixed baffle 7 and the traction belt 4 is provided on the outer wall of the sliding rod 31. The connecting member 8 fixes the sliding rod 31 to the end of the traction belt 4. When the sliding rod 31 slides, it drives the rotating disk 2 to rotate.

[0043] Reference Figure 4 and Figure 5A bracket 25 is welded and fixed to the side wall of the fixed baffle 7. The shape of the bracket 25 is preferably set to be U-shaped. The connecting component 8 includes a pressing piece 15 hinged on the inner wall of the bracket 25 and a locking block 16 integrally fixed to the pressing piece 15 on the side close to the fixed baffle 7. A plurality of protrusions 17 are welded and fixed at even intervals on the side of the locking block 16 away from the pressing piece 15. In this application, the shape of the protrusions 17 is preferably set to be conical, and the protrusions 17 are arranged in a straight line along the length direction of the locking block 16. The staff first rotates the pressing piece 15 in the direction away from the fixed baffle 7, inserts the end of the traction belt 4 between the pressing piece 15 and the fixed baffle 7, and then rotates the pressing piece 15 in the direction close to the fixed baffle 7 so that the protrusions 17 penetrate the traction belt 4, thereby achieving the connection between the fixed baffle 7 and the traction belt 4.

[0044] Reference Figure 3 and Figure 4 In the present application, the rotating disk 2 is hollow, and a rotating shaft 27 is rotatably connected to the inner wall of the rotating disk 2. The rotating shaft 27 is coaxially arranged with the rotating disk 2, and a jumper 3 is welded and fixed to the end of the rotating shaft 27. In the present application, the jumper 3 is preferably made of conductive metal material, and the light strip 30 is electrically connected to the side wall of the jumper 3 through a wire; a conductive seat 6 is fixed to the inner wall of the support 26 by screws, and a battery box is installed on the side wall of the conductive seat 6. A button battery is installed on the inner wall of the battery box, and the light strip 30 is electrically connected to the negative pole on the battery box through a wire. When the traction belt 4 pulls the rotating disk 2 to rotate, it drives the jumper 3 to contact the side wall of the conductive seat 6, so that the light strip 30 is conductive and the light strip 30 emits light.

[0045] Reference Figure 4 A first support block 10 is welded and fixed to one end of the conductive seat 6, and a second support block 11 is welded and fixed to the other end. The first support block 10 and the second support block 11 are both located on the rotation path of the jumper 3. The first support block 10 and the second support block 11 are both made of insulating material. The setting of the first support block 10 and the second support block 11 blocks the jumper 3 to prevent the jumper 3 from rotating on its own and contacting the conductive seat 6, saving resources.

[0046] Reference Figure 3 and Figure 4The rotating shaft 27 can slide along the axial direction of the rotating disk 2, and a number of limit blocks 5 are welded and fixed on the side wall of the rotating disk 2. In the present application, two limit blocks 5 are preferably provided, and the two limit blocks 5 are located on the diameter of the rotating disk 2. The two limit blocks 5 are arranged in opposite directions along the axis of the rotating disk 2. The setting of the limit blocks 5 blocks the overlap piece 3, so that the rotating disk 2 drives the overlap piece 3 to rotate synchronously; the side walls of the first support block 10 and the second support block 11 are provided with guiding inclined surfaces. After the rotating disk 2 drives the overlap piece 3 to rotate to the position of the first support block 10 or the second support block 11, the rotating shaft 27 slides under the guidance of the guiding inclined surface, and the overlap piece 3 contacts the side wall of the conductive seat 6, thereby making the light strip 3 conductive.

[0047] Reference Figure 4 A first elastic member 12 is provided on the inner wall of the support 26 for returning the overlapping piece 3 to its original position. In the present application, the first elastic member 12 is preferably a spring. One end of the first elastic member 12 is welded and fixed to the inner wall of the support 26, and the other end is welded and fixed to the outer wall of the rotating shaft 27. The first elastic member 12 is stretched in the process of the first support block 10 and the second support block driving the rotating shaft 27 to slide. When the overlapping piece 3 bypasses the first support block 10 and the second support block 11, the overlapping piece 3 is restored to its original position under the action of the first elastic member 12's own rebound force.

[0048] Reference Figure 4 A torsion spring 28 is provided on the side wall of the rotating disk 2, one end of the torsion spring 28 is welded and fixed to the outer wall of the rotating disk 2, and the other end is welded and fixed to the inner wall of the support 26. When the fixed baffle 7 moves away from the rotating disk 2, it drives the traction belt 4 to move, and the traction belt 4 pulls the rotating disk 2 to rotate. When the staff is removing the fixed baffle 7, it is necessary to slide the fixed baffle 7 toward the direction of the rotating disk 2. At this time, under the action of the self-rebound force of the torsion spring 28, the rotating disk 2 drives the fixed baffle 7 to slide.

[0049] The second embodiment of the present application is a data acquisition card that is easy to install. The implementation principle is as follows: the staff drives the sliding rod 31 to slide in the sliding groove 21, so that the overlapping piece 3 contacts the side wall of the conductive seat 6, the light strip 30 wires light up, and the mounting plate 1 is fixed to the inner wall of the data device by screws under the illumination of the light strip 30; the sliding rod 31 is driven to slide in the direction away from the rotating disk 2, and the limiting piece 14 is inserted into the mounting hole on the inner wall of the data device, and the fixed baffle 7 is fixed away from one end of the rotating disk 2 under the elastic action of the limiting piece 14 and the clamping block 13. At this time, the overlapping piece 3 passes the position of the first support block 10 and leaves the conductive seat 6, and the light strip 30 is powered off; when the data acquisition card needs to be disassembled separately, the data acquisition When the data acquisition card is collected for maintenance, the fixed baffle 7 is pulled in the direction of the rotating disk 2. The rotating disk 2 is rotated under the action of the self-rebound force of the torsion spring 28, driving the overlapping piece 3 to rotate past the position of the second support block 11, and the light strip 30 is powered on for lighting. The two positioning blocks 23 are removed and the fixed baffle 7 is pulled away from the rotating disk 2, so that the sliding rod 31 slides away from the sliding groove 21, thereby realizing the disassembly of the data acquisition card; when reinstalling the data acquisition card, the traction belt 4 is pulled, the light strip 30 is illuminated, the sliding rod 31 is slid into the sliding groove 21, and the fixed baffle 7 is fixed to the mounting plate 1. The staff turns on the light strip 30 for lighting during the process of disassembling and installing the data acquisition card, providing convenience for the staff.

[0050] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application.
