Description

Technical Field

[0001] This utility model belongs to the field of vibration analyzer assembly technology, specifically relating to a housing assembly structure for a vibration analyzer. Background Technology

[0002] Vibration analyzers are precision instruments designed based on the piezoelectric effect principle. They convert mechanical stress into electrical signals through quartz crystals or artificially polarized ceramics for vibration measurement. They are widely used in fields such as machinery manufacturing, power metallurgy, wind power, and aerospace, and are core tools for equipment condition monitoring and predictive maintenance.

[0003] Existing vibration analyzers require multiple side plates to be installed on the internal frame during assembly. Each side plate requires at least four screws for installation and fixation. This results in the use of a large number of screws during housing assembly, greatly increasing the complexity of installation and reducing installation efficiency.

[0004] Therefore, a housing assembly structure for a vibration analyzer is proposed. Summary of the Invention

[0005] This invention provides a housing assembly structure for a vibration analyzer, the purpose of which is to solve the problems mentioned above.

[0006] This utility model provides a housing assembly structure for a vibration analyzer, including a housing frame; a top cover and a bottom cover located above and below the housing frame; a side plate located on the outer side of the housing frame; mounting holes on the outer side wall of the side plate; a movable hole on one side outer wall of the housing frame; a limiting groove on the inner side wall of the movable hole; and slots at the top and bottom of the housing frame. The fastening assembly includes: a movable column that movably passes through the movable hole; a limiting block located at one end of the movable column near the inside of the limiting groove; an inclined groove on the outer side wall of the limiting block; a protruding column at the other end of the movable column; a rotating groove on the outer side wall of the protruding column; a fastening block rotating within the rotating groove; an insert block inserted into the slot; an inclined surface on the bottom side wall of the insert block; and a fitting block at the top of the insert block.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] Example 1

[0027] Reference Figure 1-3 This utility model embodiment proposes a housing assembly structure for a vibration analyzer, including a housing frame 1. An movable hole 11 is provided on the outer side wall of the housing frame 1. A limiting groove 12 is provided on one side inner wall of the movable hole 11. Slots 13 are provided at the top and bottom of the housing frame 1. The movable hole 11 and the slots 13 are connected to the limiting grooves 12. The limiting grooves 12 and the slots 13 are perpendicular to each other, and the limiting grooves 12 and the movable hole 11 are on the same horizontal axis. Through the connected structure, the fastening components 6 can be linked inside, thereby achieving the purpose of fastening.

[0028] A top cover 2 is provided on the upper part of the shell frame 1, and a bottom cover 3 is provided on the lower part of the shell frame 1. A side plate 4 is provided on the outer side of the shell frame 1, and an installation hole 5 is provided on the outer side wall of the side plate 4.

[0029] The movable hole 11 has a movable column 61 in the fastening assembly 6 that is movably inserted through it. A limit block 62 is located at one end of the movable column 61 near the inside of the limiting groove 12. A spring is installed between the limit block 62 and the limiting groove 12. An inclined groove 63 is formed on the outer wall of the limit block 62. The other end of the movable column 61 has a protruding column 64. A rotating groove 65 is formed on the outer wall of the protruding column 64. A fastening block 66 is rotatably connected inside the rotating groove 65. A torsion spring is installed between the fastening block 66 and the rotating groove 65. The torsion spring keeps the fastening block 66 in an open state, thus achieving the fastening function. The inward rotation of block 66 allows the mounting hole 5 on the side plate 4 to be fitted onto the movable column 61. An inclined wall that fits with the fastening block 66 is provided on one side inner wall of the rotating groove 65. One end of the fastening block 66 is provided with a flat surface. The inclined wall can limit the rotation direction of one side of the fastening block 66, limiting the maximum rotation angle of the fastening block 66. Thus, when the flat surface at one end of the fastening block 66 presses against the side plate 4, the side plate 4 can be fastened. A plug 67 is inserted into the slot 13. One end of the plug 67 is provided with an inclined surface 68 near the side wall, and the other end of the plug 67 is provided with a fitting block 69.

[0030] Specifically, during the assembly of the vibration analyzer housing, under the gravity of one side of the fastening block 66 and the rotation of the other side of the fastening block 66 inside the rotating groove 65, one side of the fastening block 66 rotates toward the movable column 61. At this time, the fastening block 66 does not protrude from the outer circumference of the movable column 61. Then, the mounting hole 5 on the side plate 4 is aligned with the movable column 61 on the housing frame 1. The side plate 4 will first press the fastening block 66. After being pressed, the fastening block 66 rotates toward the movable column 61. When the mounting hole 5 on the side plate 4 is fitted onto the outside of the movable column 61, under the action of the return force of the torsion spring, the fastening block 66 resets and rotates. One side of the fastening block 66 is located outside the mounting hole 5. After the initial docking of the four side plates 4 with the housing frame 1 is completed;

[0031] The top cover 2 and bottom cover 3 are fixed to the top and bottom of the shell frame 1 respectively. When fixing the top cover 2 and bottom cover 3, the top cover 2 and bottom cover 3 are moved toward the shell frame 1. The insert 67 on the top cover 2 and bottom cover 3 is inserted into the slot 13 on the shell frame 1. When the insert 67 contacts the inclined groove 63 on the limiting block 62, under the guidance of the inclined surface, the vertically moving insert 67 pushes the limiting block 62 to move horizontally in the limiting groove 12. At this time, the movable column 61 and the protruding column 64 move toward the interior of the movable hole 11. The fastening block 66 gradually presses and adheres to the side plate 4 to achieve fastening of the side plate 4 and ensure that the side plate 4 is tightly attached to the outer wall of the shell frame 1. Finally, the top cover 2 and bottom cover 3 are fixed to the top and bottom of the shell frame 1 respectively with screws.

[0032] The four side panels are easy and convenient to assemble, requiring no screws for fixing, resulting in high assembly efficiency.

[0033] Example 2

[0034] Reference Figure 1 and Figure 4 Based on the above embodiments, this utility model also proposes a housing assembly structure for a vibration analyzer, including a housing frame 1, a top cover 2 on the top of the housing frame 1, and a bottom cover 3 on the bottom of the housing frame 1. Both the top cover 2 and the bottom cover 3 are fixed to the housing frame 1 by screws, allowing for installation and fixation of the top cover 2 and the bottom cover 3, ensuring their stability after installation. T-shaped grooves 21, insert blocks 67, and mating blocks are provided on the top of the top cover 2 and the bottom of the bottom cover 3. The 69 pieces are combined to form a T-shaped structure. The T-shaped structure passes through and is adapted to the T-shaped groove 21. The T-shaped groove 21 can support the mating block 69, thereby limiting the position of the T-shaped structure. In order to facilitate the disassembly of the T-shaped structure, one of the side plates 4 can be disassembled separately, which is convenient for the inspection and maintenance of the vibration analyzer. The top of the top cover 2 and the bottom of the bottom cover 3 are provided with threaded ring grooves 22 near the outer side of the T-shaped groove 21. The threaded ring groove 22 is connected to the threaded cover 23 by threaded engagement.

[0035] Specifically, to facilitate the removal of individual side plates 4, the threaded cap 23 in the vertical direction of the corresponding side plate 4 is unscrewed through the threaded connection between the threaded cap 23 and the threaded annular groove 22. After the threaded cap 23 is removed, the top of the mating block 69 loses its limit. The mating block 69 and the insert block 67 are then pulled out of the slot 13. After the insert block 67 separates from the limiting block 62, the limiting block 62 loses its horizontal limit. Under the action of the spring's rebound force, the movable column 61 moves towards the outside of the movable hole 11. There is a gap space between the side plate 4 and the housing frame 1. At this time, the side plate 4 is detached from the movable column 61, thus removing the side plate 4 and facilitating the inspection and maintenance of the vibration analyzer.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
