Description

Technical Field

[0001] This utility model belongs to the field of vibration monitoring technology, specifically relating to an integrated vibration transmitter. Background Technology

[0002] The emergence of integrated vibration transmitters has provided a more efficient and reliable solution for vibration monitoring of rotating machinery. Integrated vibration transmitters cleverly combine sensors and transmitter circuitry into one unit, integrating multiple functional modules such as vibration velocity sensors, signal processing circuits, voltage regulation circuits, voltage-to-current conversion circuits, and power polarity protection circuits. This achieves integrated processing of the entire process from vibration signal acquisition to standard signal output. For example, the existing patent with publication number CN203011399U discloses an "integrated vibration transmitter, including a housing, a circuit board inside the housing, a microcontroller and a piezoelectric sensor on the circuit board, the piezoelectric sensor being attached to the inner wall of the housing, and also including mounting threads located at the tail of the housing." It can be seen that this application describes a common type of integrated vibration transmitter.

[0003] However, in actual use, the integrated vibration transmitter in the prior art is prone to problems due to the complex and variable industrial environment. The cable plug on the top of the transmitter is connected to the transmitter by a conventional plug-in method without effective anti-detachment measures. As a result, the cable plug is easily pulled off by external force during actual use, leading to signal interruption or monitoring failure, which reduces the overall stability of use. Therefore, this utility model proposes an integrated vibration transmitter. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: an integrated vibration transmitter, comprising a vibration transmitter body threadedly mounted on the top of the machine under test and a cable plug inserted into the top of the vibration transmitter body, and further comprising...

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model improves the integrated vibration transmitter in the prior art by designing an anti-detachment structure between the vibration transmitter and the top cable plug, which can ensure the connection stability between the transmitter and the cable plug and prevent the cable plug from easily falling off due to external force.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Please see Figures 1 to 4 This is the first embodiment of the present utility model, which provides a technical solution: an integrated vibration transmitter, including a vibration transmitter body 1 threadedly mounted on the top of the machine to be tested and a cable plug 2 plugged into the top of the vibration transmitter body 1. This integrated vibration transmitter is a known technology that has been fully disclosed in the prior art. The specific structural principles of the vibration transmitter body 1 and the cable plug 2 can be found in the existing patents with publication numbers CN203011399U and CN222618033U, which will not be elaborated here.

[0024] Also includes

[0025] The anti-detachment structure 3, located at the top of the vibration transmitter body 1, includes a rectangular base 31 welded and fixed to the side of the top of the vibration transmitter body 1, a rotating base rod 32 rotatably mounted on the top of the rectangular base 31, and an anti-detachment strip 33 welded and fixed to the top surface of the rotating base rod 32. The end of the anti-detachment strip 33 extends to the top edge of the cable plug 2. The end of the anti-detachment strip 33 can effectively block and limit the cable plug 2, preventing the cable plug 2 from accidentally detaching from the vibration transmitter body 1 due to external pulling, thus ensuring the overall stability of use. If the cable plug 2 needs to be plugged in or unplugged normally in the future, the end of the anti-detachment strip 33 can be rotated away from the top edge of the cable plug 2, and there will be no more obstruction to the cable plug 2.

[0026] In this embodiment, preferably, a circular through hole 311 is provided in the rectangular base 31 for the rotating base rod 32 to pass through. The surface of the rotating base rod 32 is provided with an integral annular limiting ring 321 relative to the top and bottom of the rectangular base 31. The annular limiting ring 321 slides in contact with the rectangular base 31 and does not affect the normal rotation of the rotating base rod 32. Under the action of the annular limiting ring 321, the rotating base rod 32 will not separate from the rectangular base 31, and the rotating base rod 32 can rotate smoothly.

[0027] In this embodiment, preferably, a rubber side seat 34 is glued to the left side surface of the rectangular seat 31. The left side surface of the rectangular seat 31 has a side notch 312 communicating with the circular through hole 311. The right side of the rubber side seat 34 has an integrated U-shaped locking block 341. Both are made of rubber and will undergo elastic deformation when compressed. The bottom surface of the rotating base rod 32 has two symmetrically opened limiting grooves 322 corresponding to the U-shaped locking block 341. The U-shaped locking block 341 is embedded into the side notch 312. Furthermore, the end of the U-shaped locking block 341 is engaged in one of the limiting slots 322. When the end of the U-shaped locking block 341 is engaged in the limiting slot 322, it can restrict the rotation of the rotating base rod 32, preventing the rotating base rod 32 and the anti-detachment strip 33 from spinning, thus ensuring the stability of the anti-detachment strip 33 in blocking and limiting the cable plug 2. If the operator subsequently needs to rotate and remove the end of the anti-detachment strip 33 from the top of the cable plug 2, they only need to push the anti-detachment strip 33 horizontally with force, causing the rotation to stop. The rotating base rod 32 rotates horizontally, causing the U-shaped locking block 341 to undergo elastic deformation under significant compressive force until the end of the U-shaped locking block 341 is squeezed out of the limiting groove 322 in the initial position. This allows the rotating base rod 32 to rotate smoothly. When the rotating base rod 32 and the anti-detachment stop bar 33 rotate 180 degrees, the end of the U-shaped locking block 341 is squeezed into another limiting groove 322, achieving the limiting of the rotating base rod 32 and the anti-detachment stop bar 33 after rotation. This facilitates the normal insertion and removal of the cable plug 2 by the operator. It is worth noting that in daily use, the vibration transmitter body 1 is mainly used to monitor the vertical vibration of the machine under test. That is to say, the vibration transmitter body 1 may vibrate slightly in the vertical direction along with the machine under test. This slight vertical vibration will not affect the stability of the U-shaped locking block 341, nor will it cause deformation of the U-shaped locking block 341. Therefore, the slight vertical vibration does not affect the limiting of the rotating base rod 32 by the U-shaped locking block 341.

[0028] In this embodiment, preferably, a pinch block 331 is fixed on the top surface of the anti-detachment strip 33, and the pinch block 331 is arc-shaped, which makes it convenient for the operator to pinch the pinch block 331 and rotate and move the anti-detachment strip 33, making it easy to operate.

[0029] In this embodiment, preferably, a hexagonal base is welded and fixed to the bottom surface of the vibration transmitter body 1, and a threaded block is welded and fixed to the bottom of the hexagonal base. The threaded block is screwed into the threaded hole opened on the machine to be tested, so as to realize the stable installation of the vibration transmitter body 1. The design of the hexagonal base is suitable for use with a wrench, so that the operator can use a wrench to rotate and twist the vibration transmitter body 1, thereby realizing the twisting and disassembly operation of the vibration transmitter body 1.

[0030] Example 2

[0031] Please see Figures 1 to 5 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but with the difference that it also includes a sealing ring 5 fixed on the top surface of the vibration transmitter body 1, and the sealing ring 5 surrounds the bottom end of the cable plug 2.

[0032] In this embodiment, preferably, the inner wall of the sealing ring 5 is provided with an integral annular protrusion 51, both of which are made of rubber and will undergo elastic deformation when squeezed. The bottom surface of the cable plug 2 is provided with an annular groove 21 corresponding to the annular protrusion 51. The annular protrusion 51 is embedded in the annular groove 21, which can effectively seal and block the connection between the cable plug 2 and the vibration transmitter body 1 after the cable plug 2 is normally plugged in.

[0033] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
