Description

Technical Field

[0001] This utility model relates to the technical field of micro-vibration sensor installation, and in particular to a quick assembly and disassembly device for micro-vibration sensors. Background Technology

[0002] Traditional micro-vibration sensors are often installed using threaded connections, which require rotating the sensor or anchor rod to secure them. Over time, the anchor rod is prone to rusting, causing the threaded connection to lock up, making disassembly difficult. Furthermore, frequent rotation of the sensor can wear down the cable and affect the stability of signal transmission. Utility Model Content

[0003] In view of this, the present invention provides a quick assembly and disassembly device for a micro-vibration sensor. The base can be permanently fixed to the sensor, for example, by welding or bolting it. A contact piece is used to press against the second sidewall of the adapter, causing the first sidewall of the base to abut against the inner wall of the connecting groove. This increases the friction between the base and the adapter by increasing the interaction force between them, thereby reducing the possibility of the adapter detaching from the base. The anchor rod is threaded or welded into the mounting groove, thus fixing the anchor rod to the sensor. During disassembly, the anchor rod can be separated from the sensor by removing the contact piece or even damaging the adapter.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A quick assembly / disassembly device for a micro-vibration sensor, comprising:

[0006] A base for fixing to the top of the sensor, the outer side wall of the base is composed of a flat and vertical second side wall, and a centering groove extending into the base is provided on the second side wall.

[0007] The adapter has an upward-opening mounting groove for attaching an anchor rod and a downward-opening connecting groove. The inner wall of the connecting groove is adapted to the outer wall of the base. The adapter is detachably fixed with an abutment for extending into the connecting groove and abutting against the second side wall in an attitude perpendicular to the second side wall. One end of the abutment extends into the centering groove.

[0008] Preferably, the first sidewall is cylindrical, the two vertical sides of the second sidewall coincide with the two vertical sides of the second sidewall, and the base occupies at least 50% of the internal space of the connecting groove.

[0009] Preferably, a gasket for abutting the abutting member is fixed inside the centering groove, and an annular groove is formed on the inner wall of the centering groove to accommodate the gasket and prevent the gasket from dislodging from the centering groove.

[0010] Preferably, the opening of the centering groove is flared.

[0011] Preferably, the centering groove includes a central groove in the shape of a circular hole, a clearance groove extending upward from the opening of the central groove, and a pointing groove extending laterally outward from the side of the opening of the central groove, wherein the depth of the central groove is greater than the depth of the clearance groove and the depth of the pointing groove.

[0012] Preferably, the adapter is fixed with a plurality of magnets for attracting the sensor, and the magnets are spaced apart circumferentially.

[0013] Preferably, the adapter has a plurality of receiving slots on its sidewall for accommodating the magnet, and the adapter is coaxially threaded with a cover that can move vertically relative to the adapter and expose or cover the receiving slots laterally.

[0014] Preferably, the top of the side wall of the base has a positioning protrusion protruding out of the side wall of the base, and the inner wall of the connecting groove is provided with a positioning groove adapted to the positioning protrusion. When the positioning protrusion is located in the positioning groove and the bottom end of the adapter abuts against the sensor, the end of the abutting member is directly opposite the centering groove.

[0015] As can be seen from the above technical solution, the micro-vibration sensor quick assembly and disassembly device provided by this utility model permanently fixes the base to the sensor, for example, by welding or bolting it to the sensor. The abutment member abuts against the second side wall of the adapter, so that the first side wall of the base abuts against the inner wall of the connecting groove. By increasing the interaction force between the base and the adapter, the friction between the base and the adapter is increased, thereby reducing the possibility of the adapter and the base detaching from the connection. The anchor rod is threaded or welded in the mounting groove, thereby fixing the anchor rod to the sensor. During disassembly, the anchor rod and the sensor can be separated by removing the abutment member or even destroying the adapter. Attached Figure Description

[0025] This utility model discloses a quick assembly and disassembly device for a micro-vibration sensor. The base can be permanently fixed to the sensor, for example, by welding or bolting. A contact piece abuts against the second sidewall of the adapter, causing the first sidewall of the base to abut against the inner wall of the connecting groove.

The following is in conjunction with... Figures 1 to 6 To explain.

[0028] The specific embodiments described below are intended to help those skilled in the art understand this embodiment, but this embodiment is not limited to the specific embodiments described below.

[0029] Reference Figure 1 and Figure 2 This disclosure provides an exemplary embodiment of a quick assembly / disassembly device for a micro-vibration sensor, the device comprising:

[0030] The base 2 is used to fix the sensor 4 to the top. The outer side wall of the base 2 has a straight and vertical second side wall 22. The second side wall 22 has a centering groove 23 extending into the base 2.

[0031] The adapter 1 has an upward-opening mounting groove 12 for attaching an anchor rod and a downward-opening connecting groove 13. The inner wall of the connecting groove 13 is adapted to the outer wall of the base 2. The adapter 1 is detachably fixed with an abutment 3 for extending into the connecting groove 13 and abutting against the second side wall 22 in a posture perpendicular to the second side wall 22. One end of the abutment 3 extends into the centering groove 23.

[0032] For example, refer to Figure 3 The base 2 can be fixed to the top of the sensor 4 by welding. The base 2 is a vertically arranged column structure. The first side wall 21 on the base 2 is cylindrical. The two vertical sides of the first side wall 21 coincide with the two vertical sides of the second side wall 22 respectively. The base 2 can be regarded as either part of the two solid structures formed by cutting from its top surface along its height direction to its bottom surface.

[0033] The adapter 1 is a vertically oriented cylindrical sleeve structure. The mounting groove 12 extends from the top of the adapter 1 into the interior of the adapter 1 and is coaxially arranged with the adapter 1. The connecting groove 13 extends from the bottom of the adapter 1 into the interior of the adapter 1 and is coaxially arranged with the adapter 1. The top of the connecting groove 13 and the bottom of the mounting groove 12 retain the solid structure of the adapter 1, that is, the connecting groove 13 and the mounting groove 12 are not connected. The internal contour of the connecting groove 13 is cylindrical and matches the contour of the first side wall 21 on the base 2. That is, after the base 2 is inserted into the connecting groove 13, the inner wall of the connecting groove 13 fits against the first side wall 21 and completely covers the first side wall 21. The adapter 1 located inside the connecting groove 13 occupies 70% of the internal space of the connecting groove 13.

[0034] Reference Figure 3 and Figure 4 The central groove 23 includes a circular central groove 232, a clearance groove 231 extending upward from the opening of the central groove 232, and a directional groove 233 extending laterally outward from the side of the opening of the central groove 232. The central groove 232 is a circular groove that extends horizontally from the second sidewall 22 into the base 2, and the axis of the central groove 232 is perpendicular to the second sidewall 22. The clearance groove 231 extends in the depth direction from the second sidewall 22 into the base 2. The bottom end of the clearance groove 231 is located at the top edge of the central groove 232, and the top end of the clearance groove 231 penetrates the top surface of the base 2 vertically. The clearance groove 231 communicates with the central groove 232, and the depth of the central groove 232 is greater than the depth of the clearance groove 231. The depth direction of the pointing groove 233 extends from the second side wall 22 into the interior of the base 2. The two ends of the pointing groove 233 extend to the two side edges of the second side wall 22 respectively, and penetrate the edge of the second side wall 22 in the transverse direction. The pointing groove 233 passes through the central groove 232, which is exposed from the middle position of the pointing groove 233. The central groove 232 is connected to the pointing groove 233, and the depth of the central groove 232 is greater than the depth of the pointing groove 233.

[0035] The opening of the central groove 23 is flared, and the edge of the opening of the central groove 232 has a guide groove 234 with a recessed structure. The guide groove 234 is coaxially arranged with the central groove 232. The bottom edge of the clearance groove 231 extends to the edge of the guide groove 234, and part of the edge of the guide groove 234 expands outward from the inner wall of the guide groove 233.

[0036] The abutment 3 includes a bolt that is threadedly connected to the adapter 1. The threaded end of the bolt passes through the adapter 1 in a horizontal position and extends into the connecting groove 13. By rotating the bolt, the threaded end of the bolt can abut against the base 2, that is, against the center groove 232 on the second side wall 22, thereby increasing the friction between the base 2 and the adapter 1, and vertically engaging the adapter 1 with the base 2, reducing the possibility of the adapter 1 and the base 2 becoming disconnected.

[0037] A gasket 24 for contacting the abutment member 3 is fixed inside the center groove 23. An annular groove 235 is formed on the inner wall of the center groove 23 to accommodate the gasket 24 and prevent the gasket 24 from dislodging from the center groove 23. The annular groove 235 is formed at one end of the center groove 232 located inside the base 2. The inner diameter of the annular groove 235 is larger than the inner diameter of the center groove 232, and the annular groove 235 is coaxially arranged with the center groove 232. The gasket 24 is placed inside the annular groove 235. The thickness of the gasket 24 is less than the depth of the annular groove 235, that is, the gasket 24 can move along the axial direction of the center groove 232 inside the annular groove 235. In this way, the edge of the gasket 24 can be limited by the annular groove 235, reducing the possibility of it detaching from the interior of the central groove 232. The annular groove 235, which is deeper than the gasket 24, can also provide space for the gasket 24 to change its posture and deform. This allows the gasket 24 to increase the friction between the bolt, which serves as the abutment 3, and the adapter 1 after adjusting its posture and deforming, thus reducing the possibility of the abutment 3 and the adapter 1 detaching from each other.

[0038] The top of the side wall of the base 2 has a positioning protrusion 25 protruding from the side wall of the base 2. The positioning protrusion 25 extends vertically from the bottom of the side wall of the base 2 to the top of the side wall of the base 2. The positioning protrusion 25 has a prism structure and is integrally formed with the first side wall 21 on the base 2. The inner wall of the connecting groove 13 has a positioning groove (not shown in the figure) that is adapted to the positioning protrusion 25. The positioning groove extends vertically from the bottom end face edge of the adapter 1 into the interior of the side wall of the adapter 1. When connecting the adapter 1 and the base 2, the positioning protrusion 25 is aligned with the positioning groove, so that the positioning protrusion 25 is inserted into the positioning groove, and the first side wall 21 on the base 2 is attached to the inner wall of the connecting groove 13. The adapter 1 is moved downward. When the bottom end of the adapter 1 is flush with the bottom end of the base 2, the end of the abutment 3 is aligned with the center groove 232.

[0039] Reference Figure 5 and Figure 6The bottom end of the adapter 1 is fixed with a plurality of magnets 15 for adsorbing the sensor 4, and the magnets 15 are spaced apart circumferentially. The side wall of the adapter 1 is provided with a plurality of receiving grooves 14 for accommodating the magnets 15. The receiving grooves 14 extend vertically from the bottom end of the adapter 1 into the interior of the side wall of the adapter 1, and the receiving grooves 14 penetrate the outer side wall of the adapter 1 laterally. The bottom opening of the receiving grooves 14 has a U-shaped profile. The magnets 15 are cylindrical and placed inside the receiving grooves 14. The cylindrical side wall of the magnets 15 fits and covers the arc-shaped side wall of the receiving grooves 14 facing the connecting groove 13. Half of the cylindrical side wall of the magnets 15 is exposed from the opening of the connecting groove 13 on the side wall of the adapter 1. The adapter 1 is, for example, made of iron, and the magnets 15 are adsorbed onto the adapter 1 for fixation. The adapter 1 is coaxially threaded with a cover 11 that can move vertically relative to the adapter 1 and expose or cover the receiving groove 14 laterally. When the cover 11 rotates and moves downward, the cover 11 gradually covers the opening of the receiving groove 14 on the side wall of the adapter 1, thereby reducing the possibility of the magnet 15 detaching from the receiving groove 14. When the cover 11 rotates and moves upward, the opening of the receiving groove 14 on the side wall of the adapter 1 is exposed, thereby assisting in removing the magnet 15 from the receiving groove 14 for reuse.

[0040] In this embodiment, the base 2 is permanently fixed to the sensor 4, for example, by welding or bolting it to the sensor 4. The abutment 3 abuts against the second side wall 22 of the adapter 1, so that the first side wall 21 of the base 2 abuts against the inner wall of the connecting groove 13. By increasing the interaction force between the base 2 and the adapter 1, the friction between the base 2 and the adapter 1 is increased, thereby reducing the possibility of the adapter 1 and the base 2 becoming disconnected. The anchor rod is threaded or welded into the mounting groove 12, thereby fixing the anchor rod to the sensor 4. During disassembly, the anchor rod and the sensor 4 can be separated by removing the abutment 3 or even destroying the adapter 1.

[0041] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
