Description

Technical Field

[0001] This utility model relates to the field of fluid pump technology, and in particular to a vibration damping and sealing structure for a low-noise, high-stability fluid pump. Background Technology

[0002] The low-noise, high-stability vibration damping seal structure for fluid pumps is an integrated component designed to enhance the performance of high-end fluid pumps. It provides superior vibration suppression capabilities on top of traditional sealing functions by innovatively integrating flexible damping elements with the main seal body.

[0003] Existing shock-absorbing sealing structures are usually integrated with the fluid pump shaft. This makes it difficult to effectively disassemble the shock-absorbing sealing structure from the shaft when the material ages due to long-term use or exposure to sunlight and requires maintenance, even if the fluid pump's inspection cover is opened. As a result, maintenance personnel cannot perform local inspection or replacement of individual components and are ultimately forced to replace the entire sealing assembly. This design flaw significantly increases the equipment's maintenance costs and operational difficulty. Utility Model Content

Detailed Implementation

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example 1

[0025] Reference Figures 1-6 This is the first embodiment of the present invention. This embodiment provides a vibration damping and sealing structure for a low-noise and high-stability fluid pump. The vibration damping and sealing structure for a low-noise and high-stability fluid pump includes a main body component 100 and an installation component 200. The two work together to reduce the maintenance cost of the device.

[0026] Specifically, the main component 100 includes a fluid pump 101 and a rotating shaft 102, with the rotating shaft 102 rotatably connected inside the fluid pump 101.

[0027] A motor is installed on one side of the fluid pump 101, which drives the rotating shaft 102 to rotate. This is existing technology and will not be described in detail.

[0028] Specifically, the mounting component 200 is located on the outside of the rotating shaft 102 and includes a shock-absorbing sealing structure 201, a connector 202, a snap-fit ​​component 203, and a disassembly component 204. The shock-absorbing sealing structure 201 is located on one side of the rotating shaft 102, the connector 202 is located on one side of the shock-absorbing sealing structure 201, and the disassembly component 204 is located on one side of the connector 202.

[0029] The shock-absorbing sealing structure 201 is a single unit, which is existing technology and will not be elaborated further. Through the setting of the connector 202 and the snap-fit ​​203, the shock-absorbing sealing structure 201 is fixed to the rotating shaft 102. Through the setting of the disassembly part 204, the shock-absorbing sealing structure 201 can be disassembled independently. This solves the problem that the shock-absorbing sealing structure 201 and the rotating shaft 102 are difficult to disassemble when they are integrated, avoids the scrapping of the entire assembly, significantly saves spare parts costs and maintenance costs, and reduces the difficulty of installation and disassembly. Example 2

[0030] Reference Figures 3-6 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0031] Specifically, the connector 202 includes a connecting shaft 202a, which is fixed to one side of the shock-absorbing and sealing structure 201.

[0032] The connecting shaft 202a is cylindrical. The diameter of the connecting shaft 202a is smaller than that of the rotating shaft 102, and its length is also shorter than that of the rotating shaft 102. The rotating shaft 102 has a circular groove corresponding to the connecting shaft 202a.

[0033] Specifically, the connector 202 also includes a protrusion 202b, which is fixed to the end of the connecting shaft 202a.

[0034] The protrusion 202b is cross-shaped, and a cross groove is provided in the circular groove of the rotating shaft 102 corresponding to the protrusion 202b. The protrusion 202b is engaged with the cross groove of the rotating shaft 102, so that the rotating shaft 102 drives the connecting shaft 202a to rotate through the protrusion 202b.

[0035] Specifically, the snap-fit ​​component 203 includes a snap-fit ​​block 203a and a push post 203b. The snap-fit ​​block 203a is rotatably connected to the outside of the connecting shaft 202a, and the push post 203b is movable inside the connecting shaft 202a.

[0036] There are two locking blocks 203a. The rotating shaft 102 and the connecting shaft 202a are both provided with arc-shaped grooves corresponding to the locking blocks 203a. The locking blocks 203a rotate within the arc-shaped grooves of the rotating shaft 102 and the connecting shaft 202a. A rectangular block is provided on one side of the locking block 203a. The pushing column 203b is provided with a long groove corresponding to the rectangular block of the locking block 203a. By pressing the rectangular block of the locking block 203a with the inner wall of the long groove of the pushing column 203b, the locking block 203a rotates, thereby completing the installation and disassembly of the device. This significantly saves spare parts costs and maintenance expenses, and reduces the difficulty of maintenance. By making the groove of the pushing column 203b a long groove, the situation of the pushing column 203b accidentally hitting the locking block 203a is avoided, thereby improving the stability of the device.

[0037] Specifically, the snap-fit ​​component 203 also includes a circular plate 203c and a spring 203d. The circular plate 203c is fixed to one side of the push post 203b, and the two ends of the spring 203d are fixed to the connecting shaft 202a and the circular plate 203c, respectively.

[0038] The reaction force of the spring 203d pushes the circular plate 203c to move, so that the circular plate 203c always drives the push column 203b to squeeze the locking block 203a, thereby making the locking block 203a engage with the arc groove of the shaft 102. This not only ensures the stability of the device, but also facilitates the fixing of the device.

[0039] Specifically, the snap-fit ​​component 203 also includes a threaded ring 203e, which is rotatably connected to the outside of the connecting shaft 202a.

[0040] The outer side of the connecting shaft 202a is also threaded with a threaded ring 203e. The inner thread of the threaded ring 203e is a reverse thread. This design makes the connecting shaft 202a more and more secure as it rotates, thereby ensuring the stability of the device while facilitating disassembly and maintenance, and reducing the maintenance cost of the device.

[0041] Specifically, the disassembly component 204 includes a round rod 204a and a push plate 204b. The round rod 204a is fixed to one side of the push column 203b, and the push plate 204b is fixed to the outside of the round rod 204a.

[0042] The round rod 204a moves within the connecting shaft 202a. The push plate 204b is rectangular, and the connecting shaft 202a has a groove corresponding to the push plate 204b. The push plate 204b moves within the groove. By pulling the push plate 204b, the round rod 204a is moved. The round rod 204a moves the pushing column 203b. The pushing column 203b presses against the rectangular block of the locking block 203a. The locking block 203a rotates under pressure, causing it to separate from the groove of the shaft 102. The locking block 203a rotates back into the connecting shaft 202a, thus completing the disassembly of the device and reducing its maintenance cost.

[0043] During use and disassembly, first rotate the threaded ring 203e to separate it from the end of the rotating shaft 102. Then, pull the push plate 204b to move the round rod 204a. The round rod 204a moves the push column 203b, which presses against the rectangular block of the locking block 203a. The locking block 203a rotates under pressure, causing it to separate from the groove of the shaft 102. The locking block 203a then rotates into the connecting shaft 202a, thus completing the disassembly of the device and reducing its maintenance costs.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
