Description

Technical Field

[0001] This utility model relates to the field of sensor installation technology, and in particular to a mounting fixture for a small-aperture micro-vibration sensor. Background Technology

[0002] Micro-vibration sensors are sensitive devices specifically designed to detect extremely weak vibrations or movements, and are widely used in medical, industrial, consumer electronics, and military fields. The micro-vibration sensor in this technology is primarily installed within a small hole 100 several meters to tens of meters deep, and then sealed to the hole 100 with resin. Due to the small diameter (a few centimeters to tens of centimeters) and depth of the hole 100, the traditional method involves inserting the micro-vibration sensor and data acquisition cable, and then pushing it with a thin rod (or anchor rod). This method is prone to problems such as improper installation and damage to the micro-vibration sensor from impacts by the thin rod (or anchor rod). Therefore, the traditional method is no longer sufficient to meet the installation requirements.

[0003] Therefore, there is an urgent need to propose a simple and reliable mounting fixture for small-aperture micro-vibration sensors. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a mounting fixture for a small-aperture micro-vibration sensor. The technical solution adopted by this utility model is as follows:

[0005] A fixture for mounting a small-aperture micro-vibration sensor includes a lower spring mounting base fixed to the bottom of the micro-vibration sensor, an upper micro-vibration sensor mounting base fixed to the top of the micro-vibration sensor, a lower fastening buckle assembly fixed to the upper micro-vibration sensor mounting base, an upper spring mounting base disposed above the lower fastening buckle assembly, an upper fastening buckle assembly disposed at the bottom of the upper spring mounting base and matching the lower fastening buckle assembly, a spring disposed between the lower and upper fastening buckle assemblies, several springs connected at the top to the upper spring mounting base and at the bottom to the lower spring mounting base and arranged in a circular array around the micro-vibration sensor, and an operating rod detachably connected to the top of the upper spring mounting base. When the lower spring mounting base is placed at the bottom of the small hole, the operating rod pushes the upper fastening buckle assembly to engage within the lower fastening buckle assembly, and the springs are pressed against the inner wall of the small hole.

[0006] Furthermore, at least two reeds are provided.

[0007] Furthermore, the top of the mounting base on the reed is provided with an operating rod connection hole; the bottom of the operating rod is provided with a threaded portion; the threaded portion is connected to the operating rod connection hole.

[0008] Furthermore, the mounting base of the micro-vibration sensor adopts a split structure, and a latch is provided on the mounting base of the micro-vibration sensor.

[0009] Furthermore, the mounting base of the micro-vibration sensor adopts a split structure, and the mounting base of the micro-vibration sensor is provided with a clamping connection hole; a connecting screw is provided in the clamping connection hole.

[0010] Furthermore, the lower mounting base of the spring is provided with a first notch corresponding to each spring on its periphery; a lower connecting hole for the spring is provided on the first notch; the upper mounting base of the spring is provided with a second notch corresponding to each spring on its periphery; an upper connecting hole for the spring is provided on the second notch; and the spring is connected to the lower connecting hole and the upper connecting hole for the spring respectively.

[0011] Furthermore, an upper limit ring is provided on the upper part of the lower mounting base of the reed; the micro-vibration sensor is sleeved inside the upper limit ring and is fixedly connected to the lower mounting base of the reed.

[0012] Furthermore, the lower fastening buckle assembly includes a fastening connecting ring fixed on the mounting base of the micro-vibration sensor, and a locking groove with a circular cross-section opened in the fastening connecting ring; the upper fastening buckle assembly includes an upper support ring fixed on the bottom of the mounting base of the spring plate, and a locking boss ring disposed at the lower part of the upper support ring and matching the locking groove.

[0013] Furthermore, the fastening ring has several first stepped holes arranged in a ring array; the first stepped holes are provided through the locking slot.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) This utility model sets up a lower mounting base for the spring, an upper mounting base for the spring, a spring, and a spring, so that the lower mounting base for the spring and the upper mounting base for the spring provide elastic support. When the spring enters the small hole, the spring retracts inward under the pushing action of the spring, that is, it approaches the micro-vibration sensor. When the micro-vibration sensor reaches the bottom of the small hole, the operating rod pushes the upper mounting base for the spring, compresses the spring, and causes the middle part of the spring to bend outward and press against the inner wall of the small hole, ensuring its support reliability.

[0016] (2) The present invention provides a lower fastening buckle assembly and an upper fastening buckle assembly between the mounting base on the micro vibration sensor and the mounting base on the spring. When the operating rod pushes the mounting base on the spring, the upper fastening buckle assembly is engaged in the lower fastening buckle assembly, which can hold and support the spring so that the operating rod can be removed. Its installation is efficient and reliable.

[0017] (3) The present invention adopts a split micro-vibration sensor mounting base, which is connected by latch or clamping connection holes and connecting screws, which facilitates reliable installation of the upper part of the micro-vibration sensor.

[0018] (4) The present invention has an operating rod connection hole on the mounting seat of the reed to facilitate threaded connection with the operating rod, and its installation and disassembly are convenient and reliable.

[0019] (5) This utility model has an upper limit ring so that the lower part of the micro-vibration sensor can be fitted in and then fixedly connected to the lower mounting base of the spring, which makes the installation reliable.

[0020] In summary, this utility model has the advantages of simple structure and reliable installation, and has high practical and promotional value in the field of sensor installation technology. Attached Figure Description
