Description
Technical Field
[0001] This utility model relates to the field of sensor brackets, and in particular to a modular mounting bracket for preventing loosening of vibration sensors in electromechanical equipment. Background Technology
[0002] In modern industrial production, the stable operation of electromechanical equipment is crucial for production efficiency and product quality. Vibration sensors, as an important tool for monitoring the operating status of electromechanical equipment, can detect the vibration of the equipment in real time, providing key data for equipment fault diagnosis and maintenance.
[0003] Existing methods for fixing vibration sensors to electromechanical equipment vary depending on the type of mounting bracket. For example, bolt-fixed brackets require tools to secure the bracket to the pre-set mounting position on the equipment using bolts before the sensor is mounted on the bracket.
[0004] However, electromechanical equipment generates vibrations of varying degrees during operation. When fixed at only a single point, the sensor is prone to swaying or swinging around the fixed point under the complex vibrations of the equipment. Especially when the vibration direction of the equipment is variable and has a large amplitude, single-point fixing cannot provide sufficient constraint, causing the sensor's installation position to shift, thus affecting measurement accuracy. Over time, it may also lead to poor contact between the sensor and the equipment surface, further reducing the reliability of the measurement data. Therefore, to address the above-mentioned problems, a modular mounting bracket for preventing loosening of vibration sensors in electromechanical equipment has been developed. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a modular mounting bracket for preventing loosening of vibration sensors in electromechanical equipment, which aims to solve the problem in the prior art that "when only a single point is fixed, the sensor is prone to shaking or swaying around the fixed point under the condition of complex vibration of electromechanical equipment".
[0006] To achieve the above objectives, this utility model adopts the following technical solution: a modular mounting bracket for preventing loosening of vibration sensors in electromechanical equipment, comprising a mounting bracket, a bidirectional screw rotatably connected to the inner wall of the mounting bracket, a gear fixedly connected to the outer extension end of the bidirectional screw, a fixing mechanism provided at the top of the mounting bracket, a limiting mechanism provided at the top of the mounting bracket, the fixing mechanism comprising a threaded slider, the inner wall of the threaded slider being threadedly connected to the outer wall of the bidirectional screw, a limiting disk fixedly connected to the top of the threaded slider, a vertical rod slidably connected to the inner wall of the limiting disk, a clamping block hinged to the bottom of the vertical rod, a connecting rod A fixedly connected to the top of the vertical rod, and a geared disc slidably connected to the extension end of the connecting rod A.
[0007] As a further description of the above technical solution: the outer wall of the gear disk is provided with an annular groove, and the outer wall of the connecting rod A is slidably connected to the inner wall of the annular groove provided on the outer wall of the gear disk.
[0008] As a further description of the above technical solution: there are two sets of fixing mechanisms, and the two sets of fixing mechanisms are symmetrically arranged at the left and right ends of the mounting bracket, and the outer walls of the two sets of vertical rods are fixedly connected with connecting rods B.
[0009] As a further description of the above technical solution: the outer wall of the connecting rod B is slidably connected to an inner sliding rod, and the inner surface of the clamping block is arc-shaped.
[0010] As a further description of the above technical solution: the limiting mechanism includes a limiting plate, which is inserted into the top of the mounting bracket. The top of the limiting plate is fixedly connected with an upper tooth, and the bottom of the limiting plate is fixedly connected with a lower tooth.
[0011] As a further description of the above technical solution: the outer wall of the limiting plate is threaded with bolts, and the outer left side of the mounting bracket is provided with a threaded hole.

[0014] This utility model has the following beneficial effects:
[0015] 1. In this utility model, by rotating the gear plate, the annular groove on its outer wall drives the connecting rod A to move, so that the vertical rod moves up and down along the vertical opening of the limiting plate, realizing the clamping or loosening operation of the clamping block on the vibration sensor body, which is convenient for the staff to fix and disassemble the vibration sensor. When one set of fixing mechanisms is adjusted, the other set will work at the same time, fixing from both the front and rear ends of the vibration sensor body at the same time, so that the fixing force is uniform, improving the fixing efficiency and reliability.
[0016] 2. In this utility model, the upper teeth of the limiting plate are inserted into the outer wall of the gear disk, and the lower teeth at the bottom mesh with the outer wall of the gear, thus providing double limiting for the gear disk and gear.

Detailed Implementation
[0023] 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.
[0024] Reference Figures 1-3This utility model provides an embodiment of a modular mounting bracket for preventing loosening of vibration sensors in electromechanical equipment. The bracket includes a mounting bracket 1, which serves as the basic support component of the entire mounting structure, providing a platform for the installation and fixation of other components. A bidirectional screw 2 is rotatably connected to the inner wall of the mounting bracket 1. The bidirectional screw 2 allows for adjustment of the spacing between mating components through its rotation, a feature common in existing technologies. A gear 3 is fixedly connected to the outer extension end of the bidirectional screw 2. A fixing mechanism 4 is provided at the top of the mounting bracket 1 to ensure stable installation on the bracket 1 and prevent displacement or shaking of the vibration sensor during operation. To ensure the accuracy of the measurement data, a limit mechanism 7 is provided on the top of the mounting bracket 1. The fixing mechanism 4 includes a threaded slider 411, the inner wall of which is threadedly connected to the outer wall of the bidirectional screw 2. When the bidirectional screw 2 rotates, the threaded slider 411 moves along the axial direction of the bidirectional screw 2. A limit plate 412 is fixedly connected to the top of the threaded slider 411, and a vertical rod 413 is slidably connected to the inner wall of the limit plate 412. The limit plate 412 provides a limiting and guiding function for the sliding of the vertical rod 413, ensuring that the vertical rod 413 can only move in the direction specified by the limit plate 412. A clamping block 4 is hinged to the bottom of the vertical rod 413. 14. The clamping block 414 is used to directly contact and clamp the vibration sensor body 5. Its hinged design allows the clamping block 414 to better fit the shape of the vibration sensor body 5 when in contact, improving the fixing effect. A connecting rod A415 is fixedly connected to the top of the vertical rod 413. A toothed disk 416 is slidably connected to the extension end of the connecting rod A415. An annular groove is opened on the outer wall of the toothed disk 416. The outer wall of the connecting rod A415 is slidably connected to the inner wall of the annular groove on the outer wall of the toothed disk 416. By rotating the toothed disk 416, the connecting rod A415 can drive the vertical rod 413 through the cooperation of the annular groove and the connecting rod A415. 3. The movable mechanism facilitates operation by staff to fix the vibration sensor body 5. There are two sets of fixing mechanisms 4, which are symmetrically arranged at the left and right ends of the mounting bracket 1. The outer walls of the two sets of vertical rods 413 are fixedly connected to connecting rods B417. The outer walls of connecting rods B417 are slidably connected to inner slide rods 418. The arrangement of connecting rods B417 and inner slide rods 418 enables the two sets of fixing mechanisms 4 to work together. When one set of fixing mechanisms 4 is adjusted, the other set of fixing mechanisms 4 can be driven to work simultaneously through the transmission of connecting rods B417 and inner slide rods 418. The inner surface of the clamping block 414 is arc-shaped.
[0025] Reference Figure 1 , Figure 4The limiting mechanism 7 includes a limiting plate 711, which is inserted into the top of the mounting bracket 1. An upper tooth 712 is fixedly connected to the top of the limiting plate 711, and a lower tooth 713 is fixedly connected to the bottom of the limiting plate 711. As a single limiting component, the limiting plate 711 can simultaneously limit the gear 3 and the gear disc 416, preventing them from rotating during use and ensuring the stability of the fixing mechanism 4 and the bidirectional screw 2. Bolts 714 are threaded onto the outer wall of the limiting plate 711, and a threaded hole 6 is provided on the left side of the outer wall of the mounting bracket 1. The outer wall of the upper tooth 712 is inserted into the outer wall of the gear plate 416, thereby preventing the position of the vertical rod 413 and the clamping block 414 from changing and ensuring the fixed state of the vibration sensor body 5. The lower tooth 713 meshes with the outer wall of the gear 3. The top of the mounting bracket 1 is provided with a mounting hole. The outer wall of the clamping block 414 is detachably connected to the vibration sensor body 5. The detachable connection means that the vibration sensor body 5 can be easily removed from the mounting bracket 1 when maintenance, replacement or calibration is required, which improves the maintainability and flexibility of the equipment.
[0026] Working principle: By rotating the gear disk 416, the connecting rod moves along the arc-shaped groove on the gear disk 416, thereby moving the vertical rod 413 connected to the connecting rod A415 downward along the vertical opening of the limiting disk 412. This causes the clamping block 414 hinged at the bottom of the vertical rod 413 to fix the vibration sensor body 5. A connecting rod B417 is connected to the outer wall of the vertical rod 413. When one set of fixing mechanisms 4 is adjusted, it drives the other set of fixing mechanisms 4 to work simultaneously, thereby fixing both ends of the vibration sensor body 5 at the same time. The spacing between the fixing mechanisms 4 is adjusted by the bidirectional screw 2. A limiting plate 711 is inserted into the mounting bracket 1. The upper teeth 712 at the top of the limiting plate 711 fix and limit the gear plate, and the lower teeth 713 below the limiting plate 711 fix and limit the gear 3. Finally, the limiting plate 711 is fixed by bolts 714, thus ensuring that the gear 3 and the gear disk 416 are simultaneously limited to prevent the whole from loosening.
[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
