Description

Technical Field

[0001] The present invention relates to the technical field of vacuum pumps, and in particular to a vacuum pump. Background Art

[0002] A vacuum pump refers to a device or equipment that uses mechanical, physical, chemical or physical methods to evacuate the container to obtain a vacuum. Generally speaking, a vacuum pump is a device that uses various methods to improve, generate and maintain a vacuum in a closed space.

[0003] The installation of shock-absorbing devices for vacuum pumps on the current market is relatively cumbersome. Most of the time, bolts and metal plates are used to fix the shock-absorbing devices to the surface or under the base of the vacuum pump. However, over time, long-term shock absorption causes the elasticity of the spring inside the shock-absorbing device to decrease, and the shock absorption effect becomes weaker. In addition, after the vacuum pump has been working for a long time, the temperature of the pump body continues to rise, which will have a negative impact on the normal operation of the pump body.

[0004] In view of this, the present invention proposes a vacuum pump to solve the above problems. Summary of the Invention

[0011] Preferably, a slider is fixedly connected to the inner wall of the second circular hole, a sliding groove is provided on the side of the pressing block, and the pressing block is slidably connected to the inner wall of the second circular hole through the slider and the sliding groove.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Please refer to Figure 1-6The present invention provides a technical solution: a vacuum pump, comprising a base plate 1, the base plate 1 is provided with a support leg 14, the upper surface of the base plate 1 is provided with a circular hole, the inner wall of the circular hole is slidably provided with a cylinder 3, the outer wall of the cylinder 3 is detachably fixedly connected to the motor 2 and the pump housing 16 through a base, the outer surface of the pump housing 16 is paved with a heat dissipation component, the heat dissipation component reduces the temperature of the pump housing 16 by heat conduction, the upper surface of the cylinder 3 is fixedly connected to a spring box 4, and the inner bottom wall of the spring box 4 is fixedly connected to a spring 5 The top of the spring 5 is fixedly connected to a pressing block 6, a second circular hole is provided on the upper surface of the spring box 4, the inner wall of the second circular hole is slidably connected to the surface of the pressing block 6, the lower surface of the pressing block 6 is fixedly connected to a support rod 7, the bottom end of the support rod 7 is fixedly connected to a thin rod 9, the bottom end of the thin rod 9 is fixedly connected to a clamping mechanism 10, and a water tank 11 is upside down on the lower surface of the base plate 1 through a shock absorbing mechanism 12, the water tank 11 stores coolant inside, and a card slot 13 is provided inside the water tank 11.

[0027] By adopting the above technical solution, when in use, first install the motor 2 and the pump casing 16 on the outer wall of the cylinder 3 through the base, and then lay the heat dissipation component on the outer surface of the pump casing 16, and quickly reduce the temperature of the pump casing 16 through heat conduction and air convection, and then press the pressing block 6, and the pressing block 6 moves to drive the support rod 7 to move. At this time, the spring 5 contracts, and the support rod 7 moves to drive the thin rod 9 to move. The thin rod 9 moves and drives the clamping mechanism 10 to move in the cylinder 3, so that the clamping mechanism 10 is successfully stuck in the card slot 13, and the pressing block 6 is released. The spring 5 resets and pushes the pressing block 6 to move upward, and the pressing block 6 moves upward to drive the support rod 7 to move upward. The support rod 7 and the thin rod 9 move upward, and the thin rod 9 moves upward to drive the clamping mechanism 10 to clamp in the clamping groove 13, and finally the base plate 1 is fixed to the ground with the support feet 14. The shock absorption system realizes the hierarchical attenuation of vibration energy by constructing a multi-stage transmission path. The mechanical vibration generated by the motor 2 and the pump casing 16 during operation is transmitted to the cylinder 3 through the base to form the first stage of shock absorption. The cylinder 3, as an axial bearing structure, transmits the vibration to the shock absorption mechanism 12 on the water tank 11 to form the second stage of shock absorption. The shock absorption mechanism 12 absorbs and eliminates the vibration energy to form the third stage of shock absorption, thereby fully improving the shock absorption effect and effectively suppressing the resonance phenomenon of the equipment.

[0028] As an embodiment of the present invention, the clamping mechanism 10 includes a first clamping block 1001 fixedly connected to the bottom end of the thin rod 9, a sliding groove is provided on the side of the first clamping block 1001, the inner wall of the sliding groove is slidably connected to a rotating shaft, the surface of the rotating shaft is fixedly connected to a second clamping block 1002, a sliding hole is provided on the side of the cylinder 3, and the upper surface of the second clamping block 1002 is slidably connected to the inner wall of the sliding hole.

[0029] By adopting the above technical solution, when the pressing block 6 drives the thin rod 9 to move, the movement of the thin rod 9 drives the movement of the first clamping block 1001, and the movement of the first clamping block 1001 drives the movement of the second clamping block 1002, ultimately clamping and fixing the clamping mechanism 10 in the clamping slot 13. This design can effectively resist displacement caused by vibration, avoid the risk of derailment of the mechanism due to vibration or impact, and ensure stable clamping and safe operation of the equipment.

[0030] As an embodiment of the present invention, the shock absorbing mechanism 12 includes a first straight plate 1201 fixedly connected to the upper surface of the water tank 11, the upper surface of the first straight plate 1201 is fixedly connected to a shock absorbing spring 1202, the top of the shock absorbing spring 1202 is fixedly connected to a second straight plate 1203, and the second straight plate 1203 is fixedly connected to the lower surface of the bottom plate 1.

[0031] By adopting the above technical solution, when the vacuum pump is running, the vibration is transmitted to the water tank 11, and the first straight plate 1201 transmits the vibration energy to the shock-absorbing spring 1202. The shock-absorbing spring 1202 is compressed or stretched in the vertical direction to absorb the vibration impact force. The elastic deformation of the shock-absorbing spring 1202 effectively attenuates the vertical vibration amplitude, effectively suppresses the resonance phenomenon of the equipment, and improves the operation stability.

[0032] As an embodiment of the present invention, the clamping slot 13 is adapted to the second clamping block 1002 .

[0033] By adopting the above technical solution, when the second clamping block 1002 is displaced by vibration, the end of the second clamping block 1002 is embedded in the slot 13, and radial extrusion force is generated through surface contact, so that the slot 13 and the second clamping block 1002 are tightly engaged, avoiding the risk of loosening caused by vibration.

[0034] As an embodiment of the present invention, the number of the shock absorbing mechanisms 12 is six, and the six shock absorbing mechanisms 12 are arranged in a rectangular array on the upper surface of the water tank 11.

[0035] By adopting the above technical solution, when the vibration of the vacuum pump is transmitted to the water tank 11, the six shock-absorbing mechanisms 12 respond synchronously, and evenly distribute the vibration energy to each shock-absorbing spring 1202 to avoid local overload.

[0036] As an embodiment of the present invention, a slider 15 is fixedly connected to the inner wall of the second circular hole, a sliding groove 8 is opened on the side of the pressing block 6, and the pressing block 6 is slidingly connected to the inner wall of the second circular hole through the slider 15 and the sliding groove 8.

[0037] By adopting the above technical solution, when the pressing block 6 is acted upon by an external force, the slider 15 moves along the sliding groove 8 , which can effectively prevent the slider 15 from falling out.

[0038] As an embodiment of the present invention, the heat dissipation component includes a heat dissipation pipe 17 that is fitted on the outer surface of the pump casing 16. The heat dissipation pipe 17 is integrally formed of a silicone rubber material with a thickness of 1mm-1.5mm. A water inlet 1701 and a water outlet 1702 are provided at both ends of the heat dissipation pipe 17. The water inlet 1701 is connected to the water outlet end of the water pump, and the water inlet end of the water pump is connected to the water tank 11. The water outlet 1702 is passed into the water tank 11 through a pipe, and the coolant is circulated between the water tank 11 and the heat dissipation pipe 17 by the water pump to achieve circulating cooling; a channel 1703 for the flow of coolant is formed inside the heat dissipation pipe 17, and a metal thermal conductive strip 18 and a soft magnetic strip 19 are provided on the inner wall surface of the heat dissipation pipe 17 close to the pump casing 16. The metal thermal conductive strip 18 and the soft magnetic strip 19 are arranged alternately and spaced apart, and the magnetic attraction surface of the soft magnetic strip 19 forms a detachable magnetic attraction connection with the surface of the pump casing 16.

[0039] As an embodiment of the present invention, the metal thermal conductive strip 18 is made of copper or aluminum material with good ductility and is made into a semi-cylindrical structure. The flat end of the metal thermal conductive strip 18 is fixedly connected to the inner wall of the heat dissipation pipe 17. The arc surface end of the metal thermal conductive strip 18 is provided with an array of tooth grooves 20. The end tooth grooves 20 of the metal thermal conductive strip 18 are filled with silicone rubber of the same material as the heat dissipation pipe 17, and the filled silicone rubber is integrally formed with the inner wall of the heat dissipation pipe 17.

[0040] By adopting the above technical solution, before the pump body works, the operator unfolds the heat dissipation tube 17 made of silicone rubber along the outer surface of the pump casing 16. The soft magnetic strip 19 on the inner wall of the heat dissipation tube 17 is automatically adsorbed on the surface of the pump casing 16 by magnetic attraction, so that it can be quickly installed and fixed. The metal thermal conductive strip 18 fits the arc contour of the pump casing 16 due to its soft characteristics, ensuring close contact between the two. Subsequently, the coolant is injected into the channel 1703 from the water tank 11 through the water inlet 1701 and circulates along the channel 1703. When the coolant flows on the surface of the metal thermal conductive strip 18, the tooth groove 20 structure greatly increases the contact area with the coolant, thereby accelerating the transfer of the heat of the pump casing 16 absorbed by the metal thermal conductive strip 18 to the coolant. Finally, the coolant returns to the water tank 11 through the water outlet 1702 to complete the circulation heat dissipation.

[0041] When it is necessary to stop heat dissipation or perform maintenance, the soft magnetic strip 19 can be released by gently pulling the heat pipe 17. The flexible silicone rubber material allows the heat pipe 17 to be easily peeled off and stored from the surface of the pump housing 16. During this process, the silicone rubber material filled in the tooth grooves 20 at both ends of the metal thermal strip 18 can effectively prevent the metal thermal strip 18 from separating from the heat pipe 17 when bending, ensuring the reliability of repeated use. This design achieves efficient heat dissipation covering the surface of the pump housing 16 while taking into account the convenience of installation and disassembly through the coordinated design of magnetic bonding, flexible thermal conductive materials and circulating cooling. The bendable and deformable properties of the heat pipe 17 itself enable it to adapt to the surface of the pump housing 16 with different curvatures, and the integrated circulation system does not require complex pipe connections, significantly improving the flexibility of application.

[0042] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
