Description

Technical Field

[0001] This utility model relates to the field of rotary vane air pump technology, specifically a rotary vane air pump base. Background Technology

[0002] A rotary vane vacuum pump, also known as a rotary vane type vacuum pump, is an oil-sealed mechanical vacuum pump used to extract gas from a sealed container to obtain a vacuum. The vanes of the rotary vane pump divide the crescent-shaped space enclosed by the rotor, pump chamber, and two end caps into three parts: A, B, and C. When the rotor rotates in the direction of the arrow, the volume of space A, which is connected to the intake port, gradually increases, and it is in the intake process; the volume of space C, which is connected to the exhaust port, gradually decreases, and it is in the exhaust process; the volume of space B, which is in the middle, gradually decreases, and it is in the compression process. As the volume of space A increases, the gas pressure decreases. The external gas pressure at the pump inlet is greater than the pressure inside space A, so gas is drawn in. When space A is isolated from the intake port, the gas begins to be compressed, and the volume gradually decreases until it finally connects to the exhaust port. When using the vacuum pump, a rotary vane vacuum pump base is required.

[0003] Some existing base structures cannot effectively reduce vibration, causing the pump body to shake easily. Ordinary metal bases are not good at absorbing vibration energy, which affects the service life and working efficiency of the air pump. Utility Model Content

[0004] The purpose of this utility model is to provide a rotary vane air pump base to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rotary vane air pump base, including a connecting base,

[0007] And a connecting component located on the side of the connecting base;

[0008] The connecting component includes a buffer mechanism disposed on the side of the connecting base;

[0009] An auxiliary mechanism is provided on the side of the connecting base.

[0010] Preferably, an mounting plate is slidably installed on the inner wall of the connecting base, and a rotary vane air pump is fixedly installed on the top of the mounting plate.

[0011] Preferably, the buffer mechanism includes a friction block and a rectangular plate.

[0012] Preferably, a triangular bracket is fixedly installed on the side wall of the baffle, and the bottom of the triangular bracket is fixedly connected to the top of the rectangular plate. The stability of the baffle can be improved by the triangular bracket.

[0013] Preferably, there are three friction blocks, all of which are of equal shape and size and are evenly distributed at the bottom of the mounting plate.

[0014] Preferably, the auxiliary mechanism includes an arc-shaped rod, a shock-absorbing air cushion, and a damper.

A rectangular rod is fixedly installed at the bottom of the connecting plate. A compression block is fixedly installed at the bottom of the rectangular rod.

[0015] Preferably, the bottom of the damper is fixedly connected to the inner wall of the connecting base, and the top of the damper is fixedly connected to the bottom of the mounting plate.

[0018] Preferably, there are four positioning blocks, all of which are of equal shape and size. The four positioning blocks are fixedly installed at the four bottom corners of the connecting base, thereby improving the stability of the connecting base.

[0019] This utility model provides a base for a rotary vane air pump. It has the following beneficial effects:

[0020] (1) When the operator uses the device, the rotary vane air pump will vibrate during operation. The rotary vane air pump drives the mounting plate to slide on the inner wall of the connecting base. When the connecting base moves, the damper will initially reduce the vibration. The rotary vane air pump will also drive the position of the friction block to drop. The friction block will slide on the inner wall of the baffle. When the friction block moves, it will slide and rub against the side wall of the rubber block. The friction between the two will further reduce the vibration. This solves the problem that some existing base structures cannot effectively reduce vibration, causing the pump body to shake easily. Ordinary metal bases are not good at absorbing vibration energy, which will affect the service life and working efficiency of the air pump.

[0021] (2) When the friction block moves, it will drive the position of the arc rod to descend. The arc rod will further drive the position of the connecting plate, the rectangular rod and the extrusion block to descend. When the extrusion block descends, it will contact the side wall of the shock-absorbing air cushion, which will effectively reduce the vibration and improve the shock absorption effect of the connecting base.

Rotary vane air pump. Detailed Implementation

[0028] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0029] Example 1: A preferred embodiment of the rotary vane air pump base provided by this utility model is as follows: Figures 1 to 5 As shown: A rotary vane air pump base includes a connecting base 1, an mounting plate 3 slidably mounted on the inner wall of the connecting base 1, and a rotary vane air pump 5 fixedly mounted on the top of the mounting plate 3.

[0030] Positioning blocks 2 are fixedly installed on the side wall of the connecting base 1. There are four positioning blocks 2, and the four positioning blocks 2 are all the same in shape and size. The four positioning blocks 2 are fixedly installed at the four bottom corners of the connecting base 1. The stability of the connecting base 1 can be improved by the positioning blocks 2.

[0031] And the connecting component 4 is located on the side of the connecting base 1;

[0032] The connecting component 4 includes a buffer mechanism 41 disposed on the side of the connecting base 1;

[0033] An auxiliary mechanism 42 is provided on the side of the connecting base 1.

[0034] The buffer mechanism 41 includes a friction block 412 and a rectangular plate 411. The friction block 412 is fixedly installed on the bottom of the mounting plate 3, and the rectangular plate 411 is fixedly installed on the inner wall of the connecting base 1. A baffle 413 is fixedly installed on the top of the rectangular plate 411, and a rubber block 415 is fixedly installed on the side wall of the baffle 413. The side wall of the rubber block 415 is slidably connected to the side wall of the friction block 412.

[0035] In this embodiment, a triangular bracket 414 is fixedly installed on the side wall of the baffle 413. The bottom of the triangular bracket 414 is fixedly connected to the top of the rectangular plate 411. The stability of the baffle 413 can be improved by the triangular bracket 414.

[0036] Furthermore, there are three friction blocks 412, all of which are equal in shape and size and are evenly distributed at the bottom of the mounting plate 3.

[0037] During the actual implementation process, when the operator uses the device, the rotary vane pump 5 will generate vibration during operation. The rotary vane pump 5 drives the mounting plate 3 to slide on the inner wall of the connecting base 1. When the connecting base 1 moves, the damper 421 will initially reduce the vibration. The rotary vane pump 5 will also drive the position of the friction block 412 to drop. The friction block 412 will slide on the inner wall of the baffle 413. When the friction block 412 moves, it will slide and rub against the side wall of the rubber block 415. The friction between the two will further reduce the vibration.

[0038] Example 2: Based on Example 1, a preferred embodiment of the rotary vane air pump base provided by this utility model is as follows: Figures 1 to 5As shown: The auxiliary mechanism 42 includes an arc-shaped rod 422, a shock-absorbing air cushion 426, and a damper 421. One end of the arc-shaped rod 422 is fixedly connected to the side wall of the friction block 412. A connecting plate 423 is fixedly installed on the side wall of the arc-shaped rod 422. A rectangular rod 424 is fixedly installed at the bottom of the connecting plate 423. A compression block 425 is fixedly installed at the bottom of the rectangular rod 424. The bottom of the shock-absorbing air cushion 426 is fixedly connected to the top of the rectangular plate 411.

[0039] In this embodiment, the bottom of the damper 421 is fixedly connected to the inner wall of the connecting base 1, and the top of the damper 421 is fixedly connected to the bottom of the mounting plate 3.

[0040] Furthermore, the shock-absorbing air cushion 426 is located directly below the extrusion block 425, and there are two shock-absorbing air cushions 426.

[0041] Furthermore, the extrusion blocks 425 are of equal shape and size, and the two extrusion blocks 425 are symmetrically arranged relative to the center face of the connecting base 1 in the left-right direction.

[0042] In the specific implementation process, when the friction block 412 moves, it will drive the position of the arc rod 422 to drop. The arc rod 422 will further drive the positions of the connecting plate 423, the rectangular rod 424 and the pressing block 425 to drop. When the pressing block 425 drops, it will contact the side wall of the shock-absorbing air cushion 426, which will effectively reduce the vibration and improve the shock absorption effect of the connecting base 1.
