Technical Field

[0001] The utility model relates to the technical field of vibration detection devices, in particular to a vibration detection device that can be connected in series, such as a microseismic monitoring device for monitoring the height of overburden rock failure. Background Art

[0002] A vibration detection device, also known as a vibration detector or a vibration measuring instrument, is an instrument used to measure, record, and analyze the vibration state of an object. The detection head of the vibration detection device is installed on the device or adsorbed on the device by magnetic attraction. When the device operates, the vibration parameters are transmitted to the main control end through the detection head.

[0003] When vibration detection devices are used in series, one detection head is connected to the detection head connected to the main control end through a connecting wire. When multiple detection heads are adsorbed or installed on the device for vibration detection, the detection head with the connecting wire inserted on the surface may vibrate with the device, which may cause the connecting wire to loosen and fall off, resulting in poor use effect and reduced stability of the series-connected detection heads. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that when multiple detection heads are adsorbed or installed on the device for vibration detection, the detection head with the connecting wire inserted on the surface may vibrate with the device, which may cause the connecting wire to loosen and fall off, resulting in poor use effect and reduced stability of the series-connected detection heads, and to propose a vibration detection device that can be connected in series.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A vibration detection device that can be connected in series includes a connecting wire. One end of the connecting wire is provided with a detection head. A magnetic attraction block is arranged at the bottom end of the detection head. A joint groove is formed on one side of the detection head. A fastening device is arranged on the outer surface of the detection head near the joint groove. The fastening device includes two screw rods. The thread directions of the outer surfaces of the two screw rods are opposite. One side of the detection head is rotatably connected with a threaded cylinder. The two ends of the inner wall of the threaded cylinder are threadedly connected with the outer surfaces of the two screw rods. One end of the screw rod away from the threaded cylinder is fixedly connected with a rectangular rod. One side of the rectangular rod is fixedly connected with a round rod. One end of the round rod is fixedly connected with an L-shaped block. One side of the L-shaped block slides on one side of the detection head.

[0006] The effect achieved by the above components is: by setting an L-shaped block, after the vibration detection device is used in series to insert the plug at one end of a detection head into the joint groove on the outer surface of another detection head, the threaded barrel can be pushed to rotate on one side of this detection head, so that the two screws move in the same direction on the inner wall of the threaded barrel, and the L-shaped block is driven to slide on one side of the detection head by the rectangular rod and the round rod, and the sides of the two L-shaped blocks close to each other are respectively clamped on the upper and lower sides of the plug, so as to limit the relative position and angle between the plug, the joint groove and the detection head, and avoid as much as possible the plug from falling off from the inside of the joint groove during the vibration detection of the detection head, which affects the normal use of the serial detection head.

[0007] Preferably, a plurality of convex strips are fixedly connected to one side of the L-shaped block, the convex strips are linearly distributed on one side of the L-shaped block, and the convex strips are made of rubber material.

[0008] The effect achieved by the above components is: by setting the convex strips made of rubber material, the friction between the L-shaped block and the surface of the plug can be increased when the convex strips are pressed against the outer surface of the plug, making the position of the plug more stable and less likely to slide.

[0009] Preferably, a plurality of rectangular strips are fixedly connected to the outer surface of the threaded barrel, and the rectangular strips are distributed in a circular shape on the outer surface of the threaded barrel.

[0010] The effect achieved by the above-mentioned components is that the threaded barrel can be pushed to rotate more conveniently by pressing the rectangular strip on the outer surface of the threaded barrel with the hand without slipping.

[0011] Preferably, a support block is fixedly connected to one side of the rectangular rod, and an end of the support block away from the rectangular rod is fixedly connected to one side of the top end of the L-shaped block.

[0012] The effect achieved by the above components is that the connection between the L-shaped block and the rectangular rod and the round rod can be further reinforced by setting the support block, so as to avoid deformation and fracture of the connection between the L-shaped block and the round rod when one side of the L-shaped block is subjected to force.

[0013] Preferably, a positioning device is provided on one side of the detection head, and the positioning device includes a slider, one end of the slider is fixedly connected to an insertion rod, a slide groove is provided on one side of the detection head, the outer surface of the slider slides on the inner wall of the slide groove, a spring is provided on one side of the slider, both ends of the spring are respectively fixedly connected to one side of the slider and one side of the inner wall of the slide groove, and a plurality of holes are provided on the circumference of the outer surface of the threaded cylinder.

[0014] The effect achieved by the above-mentioned components is: when the position of the plug inserted into the joint groove is tightened by the fastening device, the slider is pulled to move toward the direction of the threaded barrel on the inner wall of the slide groove and the spring is stretched to facilitate the rotation of the threaded barrel. After the position of the plug inserted into the joint groove is tightened, the slider is loosened and pulled to slide in the direction of the spring by the spring and the insertion rod at one end of the slider is inserted into the socket on the outer surface of the threaded barrel, thereby further restricting the position of the threaded barrel and avoiding as much as possible the autonomous rotation of the threaded barrel during the detection of the detection head, which affects the tightening effect of the fastening device on the plug.

[0015] Preferably, a positioning rod is fixedly connected to one side of the inner wall of the slide groove, and the inner wall of the sliding block slides on the outer surface of the positioning rod.

[0016] The effect achieved by the above components is: when the control slider slides on the inner wall of the slide groove, the slider will slide on the outer surface of the positioning rod. The positioning rod can further limit the angle between the slider and the slide groove to avoid the slider's angle from being deflected as much as possible.

[0017] Preferably, a U-shaped block is fixedly connected to one side of the detection head, and one side of the sliding block slides on the inner wall of the U-shaped block.

[0018] The effect achieved by the above components is that when the slider is pulled to move, part of the outer surface of the slider away from the spring end will slide on the inner wall of the U-shaped block. The U-shaped block can further limit the angles of the two ends of the slider, thereby avoiding as much as possible the uneven force on the two ends of the slider when the slider is pulled to move, resulting in deflection and breakage.

[0019] Preferably, a slot block is fixedly connected to one side of the sliding block, and a groove is formed on one side of the slot block.

[0020] The effect achieved by the above components is that pinching the groove on the outer surface of the slot block can more conveniently pull or push the slider to control the moving position of the slider.

[0022] In the utility model, by arranging a fastening device, when the vibration detection device is used in series, the two L-shaped blocks of the threaded cylinder can be rotated so that the sides approaching each other are clamped on the upper and lower sides of the plug respectively, thereby limiting the relative position and angle between the plug, the joint slot and the detection head, and avoiding as much as possible the plug from falling off from the inside of the joint slot during the vibration detection of the detection head, which affects the normal use of the serial detection head.

[0028] Example 1, as Figure 1-2 shown, a vibration detection device that can be connected in series includes a connecting wire 1. One end of the connecting wire 1 is provided with a detection head 4. A magnetic attraction block 5 is arranged at the bottom end of the detection head 4. A connector slot 6 is formed on one side of the detection head 4. A fastening device 2 is arranged on one side of the outer surface of the detection head 4 close to the connector slot 6. The fastening device 2 includes two screw rods 22. The thread directions on the outer surfaces of the two screw rods 22 are opposite. A threaded cylinder 21 is rotatably connected to one side of the detection head 4. The two ends of the inner wall of the threaded cylinder 21 are threadedly connected to the outer surfaces of the two screw rods 22. One end of the screw rod 22 away from the threaded cylinder 21 is fixedly connected with a rectangular rod 23. One side of the rectangular rod 23 is fixedly connected with a round rod 24. One end of the round rod 24 is fixedly connected with an L-shaped block 25. One side of the L-shaped block 25 slides on one side of the detection head 4. By setting the L-shaped block 25, after inserting the plug at one end of one detection head 4 into the connector slot 6 on the outer surface of another detection head 4 when using the vibration detection device in series, the threaded cylinder 21 can be pushed to rotate on one side of this detection head 4, so that the two screw rods 22 move in the same direction on the inner wall of the threaded cylinder 21. The L-shaped block 25 is driven to slide on one side of the detection head 4 through the rectangular rod 23 and the round rod 24, and the mutually approaching sides of the two L-shaped blocks 25 are respectively clamped on the upper and lower sides of the plug, restricting the relative positions and angles between the plug, the connector slot 6 and the detection head 4, and as much as possible avoiding the plug falling off from the inside of the connector slot 6 during the vibration detection process of the detection head 4, affecting the normal use of the series-connected detection head 4.

[0029] Refer to Figure 1-2As shown, in this embodiment: Several convex strips 26 are fixedly connected to one side of the L-shaped block 25. The convex strips 26 are linearly distributed on one side of the L-shaped block 25. The convex strips 26 are made of rubber material. By setting the rubber convex strips 26, the friction force between the side of the L-shaped block 25 with the convex strips 26 and the plug surface when pressing against the outer surface of the plug can be increased, and the position of the plug can be fixed more stably and is not easy to slide.

[0030] Referring to Figure 1-2 As shown, in this embodiment: Several rectangular strips 27 are fixedly connected to the outer surface of the threaded cylinder 21. The rectangular strips 27 are circumferentially distributed on the outer surface of the threaded cylinder 21. Pushing against the rectangular strips 27 on the outer surface of the threaded cylinder 21 by hand can more conveniently rotate the threaded cylinder 21 and is not easy to slip by hand. One side of the rectangular rod 23 is fixedly connected with a support block 28. One end of the support block 28 far from the rectangular rod 23 is fixedly connected with one side of the top of the L-shaped block 25. By setting the support block 28, the connection between the L-shaped block 25, the rectangular rod 23 and the round rod 24 can be further strengthened, and as much as possible, deformation and fracture at the connection between the L-shaped block 25 and the round rod 24 when one side of the L-shaped block 25 is stressed can be avoided.

[0031] Referring to Figure 1-4 As shown, in this embodiment: A positioning device 3 is arranged on one side of the detection head 4. The positioning device 3 includes a slider 32. One end of the slider 32 is fixedly connected with a plug rod 33. A chute 31 is opened on one side of the detection head 4. The outer surface of the slider 32 slides on the inner wall of the chute 31. A spring 34 is arranged on one side of the slider 32. Two ends of the spring 34 are respectively fixedly connected with one side of the slider 32 and one side of the inner wall of the chute 31. A plurality of jacks 35 are circumferentially opened on the outer surface of the threaded cylinder 21. When the position of the plug at the insertion joint groove 6 is tightened by the tightening device 2, the slider 32 is pulled to move the slider 32 on the inner wall of the chute 31 towards the threaded cylinder 21 and stretch the spring 34 to facilitate the rotation of the threaded cylinder 21. After the position of the plug at the insertion joint groove 6 is tightened, the slider 32 is released, and the spring 34 pulls the slider 32 to slide towards the spring 34 and inserts the plug rod 33 at one end of the slider 32 into the jack 35 on the outer surface of the threaded cylinder 21, further restricting the position of the threaded cylinder 21, and as much as possible, avoiding the self-rotation of the threaded cylinder 21 during the detection process of the detection head 4, which affects the tightening effect of the tightening device 2 on the plug.

[0032] Referring to Figure 2-4 As shown, in this embodiment: A positioning rod 36 is fixedly connected to one side of the inner wall of the chute 31. The inner wall of the slider 32 slides on the outer surface of the positioning rod 36. When controlling the slider 32 to slide on the inner wall of the chute 31, the slider 32 will slide on the outer surface of the positioning rod 36. The angle between the slider 32 and the chute 31 can be further restricted by the positioning rod 36, and as much as possible, the angle of the slider 32 can be prevented from being skewed.

[0033] Referring toFigure 2-4 As shown in the figure, in this embodiment: A U-shaped block 37 is fixedly connected to one side of the detection head 4. One side of the slider 32 slides on the inner wall of the U-shaped block 37. When pulling the slider 32 to move, the outer surface of the part of the slider 32 away from one end of the spring 34 will slide on the inner wall of the U-shaped block 37. Through the U-shaped block 37, the angles at both ends of the slider 32 can be further restricted, and as much as possible to avoid the angle deviation and fracture caused by uneven force at both ends when pulling the slider 32 to move. One side of the slider 32 is fixedly connected to a groove block 38. A groove is provided on one side of the groove block 38. Pinching the groove on the outer surface of the groove block 38 can more conveniently pull or push the slider 32 to control the moving position of the slider 32.

Then insert the plug on the connection line 1 at one end of the other detection head 4 into the joint groove 6 on the outer surface of the first detection head 4. Pull the groove block 38 on one side of the first detection head 4 to control the slider 32 to move on the inner wall of the sliding groove 31 towards the direction of the threaded cylinder 21 and stretch the spring 34. Then push the threaded cylinder 21 to rotate, so that the two screw rods 22 move in the same direction on the inner wall of the threaded cylinder 21, drive the L-shaped block 25 to slide on one side of the detection head 4 through the rectangular rod 23 and the round rod 24, and clamp the sides of the two L-shaped blocks 25 provided with rubber ridges 26 on the upper and lower sides of the plug respectively, to limit the relative position and angle between the plug and the joint groove 6 and the detection head 4. Then release the slider 32, and pull the slider 32 to slide towards the direction of the spring 34 through the spring 34 and insert the insertion rod 33 at one end of the slider 32 into the jack 35 on the outer surface of the threaded cylinder 21 to further limit the position of the threaded cylinder 21.
