Description

Technical Field

[0001] This utility model relates to the field of vacuum equipment technology, specifically a high-efficiency vacuum equipment. Background Technology

[0002] Vacuum equipment refers to mechanical devices used to extract gas molecules from a closed space or container, reducing the internal pressure to a vacuum state. Its core function is to reduce the number of gas molecules through physical or mechanical means to achieve the required vacuum level. Vacuum pumps are a type of vacuum equipment. In actual use, vacuum pumps are mostly fixed by screws to the front and rear covers of the pump body. However, disassembling and inspecting the pump body requires removing multiple screws, which is time-consuming and laborious, reducing the ease of disassembly of the vacuum pump.

[0003] To overcome the above-mentioned defects, in the prior art 1 (Chinese patent application number CN202420463109.8, application date 2024-03-11), a vacuum pumping device that is easy to maintain, the front cover and the rear cover are pulled to both sides of the vacuum pumping device body, which allows the front cover and the rear cover to move along with the reinforcing block. Then, through the guidance of the guide hole, the front cover and the rear cover can be released from the limit of the disassembly assembly, and the disassembly of the vacuum pumping device body can be completed. Although the prior art can realize the disassembly, inspection and maintenance of the front and rear covers, in actual use of the vacuum pump, the reciprocating motion of the piston of the piston pump will cause changes in inertial force, which will cause periodic vibration. After long-term use, vibration damage will occur, reducing the service life of the vacuum pump and making it less practical. Therefore, a high-efficiency vacuum pumping device has been proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency vacuum pumping device to solve the problem mentioned in the background art that the vacuum pumps on the market currently on the market will experience periodic vibrations due to changes in inertial force caused by the reciprocating motion of the piston in the piston pump. This vibration damage will occur after long-term use, reducing the service life of the vacuum pump and resulting in poor practicality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency vacuum pumping device, comprising a body and four dampers disposed below the body for shock protection. The bottom ends of the four dampers are connected to mounting bases. A rear cover is installed on the right side of the body, and a front cover is installed on the left side of the body. Two air inlet / outlet seats are disposed above the front cover. A plug is installed through the interior of the two air inlet / outlet seats, and a pipe is connected to the top of the plug.

[0006] Preferably, two support rods are rotatably mounted on the lower part of the machine body, and the bottom ends of the two support rods are rotatably connected to movable blocks, and the two movable blocks are slidably mounted on the upper surface of the mounting base.

[0007] Preferably, the two support rods are inclined and are symmetrically arranged about the vertical center line of the mounting base.

[0008] Preferably, two first compression springs are connected above the mounting base, and the two first compression springs have the same structure, and the moving block is connected to the side of the two first compression springs near the moving block.

[0009] Preferably, the plug has two second compression springs that slidably mount limiting blocks inside, and the two limiting blocks are arc-shaped on the side away from the plug, and the outer ends of the two limiting blocks extend through the plug into the interior of the inlet / outlet air seat.

[0010] Preferably, the inlet / outlet air seat has two push rods slidably mounted inside by two return springs, and the two push rods are symmetrically arranged about the vertical center line of the inlet / outlet air seat, and the inner ends of the two push rods correspond to limit blocks.

[0011] Preferably, the air inlet / outlet seat is provided with a coil of energy storage springs, which are evenly spaced, and a top plate is connected above the coil of energy storage springs. The top plate is slidably installed inside the air inlet / outlet seat, and a plug is correspondingly located above the top plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] (1) A damper is provided. The mounting base is connected to the bottom of the machine body by four dampers. The four dampers can increase the buffer protection performance of the machine body itself, reduce mechanical wear, protect key components, avoid resonance between the machine body and the pipeline due to rigid connection, and improve the service life of the vacuum equipment.

[0014] (2) Furthermore, while the body vibrates during use, the body will simultaneously squeeze two moving blocks on the upper surface of the mounting base through two inclined support rods to expand and move them. After the two moving blocks move to the appropriate position, they will be limited and slid to prevent them from colliding and affecting the normal use of the body.

[0015] (3) Furthermore, by means of two first compression springs connected to the upper surface of the mounting base, the two compression springs can elastically reset the two compression moving blocks, thereby allowing the machine body to be reset and moved by the two support rods, so as to achieve shock-absorbing protection for the machine body and improve the service life of the machine body.

[0016] (4) Setting limit blocks: When it is necessary to position and fix the pipeline, simply insert the plug of the pipeline connection into the inlet and outlet air seat. At this time, the two arc-shaped limit blocks will shrink and move by the squeezing of the inlet and outlet air seat. Then, the two second compression springs will automatically spring the two limit blocks into the inlet and outlet air seat by their own elasticity. This can achieve the positioning and fixing of the plug after installation, and avoid the phenomenon of the pipeline loosening and falling off due to vibration during use. The stability is better.

[0017] (5) Furthermore, when it is necessary to disassemble and replace the pipeline, simply press the two pressing rods to retract and move them through the two reset springs. This causes the two pressing rods to squeeze the two limit blocks and retract. After the two limit blocks are squeezed and retracted into the inside of the plug, a coil of pressure-accumulating spring will use its own elasticity to drive the top plate to push the plug out, thus enabling auxiliary disassembly and cleaning of the pipeline. This operation is more time-saving and labor-saving. Attached Figure Description

[0025] 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.

[0026] This utility model provides the following technical solution: a high-efficiency vacuum pumping device.

[0027] Example 1: To address the problem that existing vacuum pumps suffer from periodic vibrations due to changes in inertial force caused by the reciprocating motion of the piston, leading to vibration damage after prolonged use, reduced service life, and poor practicality, the following is disclosed: a body 1, and four dampers 7 installed below the body 1 for shock protection. The bottom ends of the four dampers 7 are connected to mounting bases 8. A rear cover 2 is installed on the right side of the body 1, and a front cover 3 is installed on the left side of the body 1. Two air inlet / outlet seats 4 are provided above the front cover 3, and plugs 5 are installed through the interior of the two air inlet / outlet seats 4. Pipes 6 are connected to the top of the plugs 5.

[0028] Two support rods 9 are rotatably mounted on the lower part of the body 1, and the bottom ends of the two support rods 9 are rotatably connected to moving blocks 10. The two moving blocks 10 are slidably mounted on the upper surface of the mounting base 8. The two support rods 9 are inclined and symmetrically arranged about the vertical center line of the mounting base 8. Two first compression springs 11 are connected to the upper part of the mounting base 8. The two first compression springs 11 have the same structure, and the moving blocks 10 are connected to the side of the two first compression springs 11 near the moving blocks 10.

[0029] like Figures 1-4 As shown, when the reciprocating motion of the piston of the piston pump causes changes in inertial force, resulting in periodic vibration, the four dampers 7 are then used to increase the buffering and protection performance of the body 1, reduce mechanical wear, protect key components, and prevent resonance between the body 1 and the pipeline 6 due to rigid connection, thereby improving the service life of the vacuum equipment.

[0030] When the body 1 vibrates, the body 1 will simultaneously press the two support rods 9 to drive the two moving blocks 10 to press and move on the upper surface of the mounting base 8. At this time, the two first compression springs 11 will use their own elastic force to elastically reset the position of the two moving blocks 10 after pressing and moving, thus avoiding the phenomenon of the body 1 and the mounting base 8 touching and being damaged. The two reset swinging support rods 9 can also press the body 1 to reset and move, so as to realize the shock-absorbing protection of the body 1 and improve the service life of the body 1.

[0031] Example 2 differs from Example 1 in that it allows for the positioning and fixation of the connected pipe 6, preventing it from loosening or falling off due to vibrations from the vacuum pump. This improves the connection stability of the pipe 6. The following is disclosed:

[0032] Inside the plug 5, two second compression springs 15 slide to install limiting blocks 14, and the side of the two limiting blocks 14 away from the plug 5 is arc-shaped. The outer ends of the two limiting blocks 14 extend through the plug 5 into the interior of the air inlet / outlet seat 4. Inside the air inlet / outlet seat 4, two return springs 13 slide to install pressing rods 12, and the two pressing rods 12 are symmetrically arranged about the vertical center line of the air inlet / outlet seat 4. The inner ends of the two pressing rods 12 correspond to the limiting blocks 14. Inside the air inlet / outlet seat 4, a coil of storage springs 17 is provided, and the coil of storage springs 17 is equally spaced. A top plate 16 is connected above the coil of storage springs 17. The top plate 16 is slidably installed inside the air inlet / outlet seat 4, and the plug 5 is located above the top plate 16.

[0033] like Figures 1-6 As shown, when it is necessary to quickly disassemble and replace the pipe 6, simply press the two pressing rods 12 to retract and move them through the two reset springs 13. This causes the two pressing rods 12 to squeeze the two limit blocks 14 and retract and move them into the inside of the plug 5. At this time, the storage spring 17, which stores the pressure, can reset and push the top plate 16, which has been squeezed down, to move upward. This allows for auxiliary disassembly and cleaning of the pipe 6, making the operation more time-saving and labor-saving.

[0034] When positioning and fixing the pipe 6, simply insert the plug 5 connected to the pipe 6 into the inlet / outlet air seat 4. At this time, the two arc-shaped limiting blocks 14 will retract and move due to the compression of the inlet / outlet air seat 4, so that the two limiting blocks 14 retract and move into the plug 5. Then, the two second compression springs 15 can automatically spring the two limiting blocks 14 into the inlet / outlet air seat 4 through their own elasticity. This can achieve the positioning and fixing of the pipe 6 after connection, and prevent the pipe 6 from loosening and falling off due to the vibration of the machine body 1 during use. This results in better stability.

[0035] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0036] The contents not described in detail in this specification are existing technologies known to those skilled in the art. Although the present invention 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 invention should be included within the protection scope of the present invention.
