Description

Technical Field

[0001] This utility model relates to the field of pump body technology, and in particular to a pump body with multiple oil drain holes. Background Technology

[0002] In existing pump body and pump cover connection structures, bolts are typically used for direct fixing. While this connection method is simple and straightforward in design, potential problems gradually emerge during long-term operation. Because the pump body is continuously subjected to fluid impact, pressure fluctuations, and periodic vibrations from mechanical operation, the bolted connection is prone to stress relaxation due to alternating loads. Over time, the preload gradually decreases, causing the fixing bolts to loosen. Once the bolts loosen, the clamping force between the pump body and pump cover will be unevenly distributed, disrupting the original seal and creating tiny gaps that can lead to leakage of gas and oil media. Therefore, this solution proposes a pump body with multiple drain holes to address these issues. Utility Model Content

[0003] The purpose of this invention is to provide a pump body with multiple oil drain holes to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a pump body having multiple oil drain holes, comprising: Pump body; A pump cover, which is disposed on the top of the pump body; A fixing bolt is provided at the connection between the pump body and the pump cover, and the fixing bolt is used to fix the pump body and the pump cover. The reinforcing component includes a top plate disposed on the top of the pump cover, a side plate fixedly connected to one side of the top plate, a bottom plate fixedly connected to the bottom of the pump body, and a connector provided at the connection between the bottom plate and the side plate.

[0005] Preferably, the top of the pump cover is provided with an oil inlet bolt, and the top of the pump cover is provided with an air extraction pipe.

[0017] 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.

[0018] This utility model provides, for example Figure 1 - Figure 4 The pump body shown has multiple oil drain holes, comprising: Pump body 1; Pump cover 2, which is located on top of pump body 1; Fixing bolt 5 is located at the connection between the pump body 1 and the pump cover 2. Fixing bolt 5 is used to fix the pump body 1 and the pump cover 2. The reinforcing component 7 includes a top plate 702 disposed on the top of the pump cover 2, a side plate 703 fixedly connected to one side of the top plate 702, a bottom plate 706 fixedly connected to the bottom of the pump body 1, and a connector provided at the connection between the bottom plate 706 and the side plate 703.

[0019] It should be noted that both the pump body 1 and the pump cover 2 are provided with threaded holes. In use, the fixing bolts 5 are passed through the threaded holes in sequence through the pump body 1 and the pump cover 2, and the two are connected by the fixing bolts 5. The top plate 702 is fixedly connected to the side plate 703, and the bottom plate 706 is fixedly connected to the pump body 1. In use, the bottom plate 706 and the side plate 703 are connected by the connector. Thus, when fixing the pump body 1 and the pump cover 2, the top plate 702 is first moved to the top of the pump cover 2, and the bottom of the side plate 703 is connected to the bottom plate 706 by the connector. Then, the position of the top plate 702 is fixed by the fixing bolts 5. In use, when the fixing bolts 5 are loose, the pump body 1 and the pump cover 2 are still pulled together by the reinforcing component 7 to avoid gas and oil leakage due to gaps between the pump body 1 and the pump cover 2.

[0020] Specifically, the top of the pump cover 2 is provided with an oil inlet bolt 201, the top of the pump cover 2 is provided with an air extraction pipe 202, the inner wall of the bottom of the pump body 1 is provided with multiple oil outlets 101, the inside of the pump body 1 is connected to a rotor 3, the middle of the rotor 3 is connected to a rotating shaft 4, and the rotating shaft 4 is connected to the inner wall of the bottom of the pump body 1.

[0021] It should be noted that there are at least two oil outlets 101. Based on the shape and structure of the pump body, the oil outlets 101 connect the inside of the pump body drive end to the outside, meeting the pressure relief requirement when the internal pressure of the drive end is too high, reducing the driving torque and operating noise of the vacuum pump, improving the service life of the vacuum pump, and ensuring its stable operation. The oil inlet bolt 201 is a hollow design. During use, the engine's oil inlet pipe is connected to the oil inlet bolt 201 to provide oil to the inside of the pump body 1. The suction pipe 202 is connected to the vacuum pipeline to obtain a vacuum. Three blades are provided on the rotor 3. During use, the rotor 3 is driven to rotate by the rotating shaft 4, so that air and oil enter the inside of the pump body 1 through the suction pipe 202 and the oil inlet bolt 201 respectively, and are discharged through at least two oil outlets 101. A gear is provided at one end of the rotating shaft 4. During use, the gear on the rotating shaft 4 is driven to rotate by the engine's drive gear, so that the rotating shaft 4 is rotated.

[0022] Specifically, a sealing groove is provided on the top of the pump body 1, and a sealing ring 6 is inserted and connected inside the sealing groove.

[0023] It should be noted that the sealing ring 6 is made of rubber, which causes the sealing ring 6 to deform when compressed. During use, the compression deformation of the pump body 1 and the pump cover 2 fills the gap at the connection between the sealing ring 6 and the pump body 1 and the pump cover 2, thereby sealing the connection between the sealing ring 6, the pump body 1 and the pump cover 2 and preventing oil and gas from leaking out from the connection between the pump body 1 and the pump cover 2.

[0024] Specifically, a through hole 701 is provided in the middle of the top plate 702, and a fixing bolt 5 is inserted into the through hole 701. A connecting groove 704 is provided on one side of the bottom plate 706, and a connecting block 705 is inserted into the connecting groove 704. The connecting block 705 is fixedly connected to one side of the side plate 703.

[0025] It should be noted that the connecting block 705 is adapted to the connecting groove 704. During use, the inner wall of the connecting groove 704 fits against the outer wall of the connecting block 705. The connecting groove 704 restricts the movement direction of the connecting block 705, and the connecting block 705 restricts the movement direction of the side plate 703 and the top plate 702. When it is necessary to fix the position of the reinforcing component 7, the connecting block 705 is first inserted into the interior of the connecting groove 704. At this time, the top plate 702 fits against the top of the pump cover 2. Then, the fixing bolt 5 is passed through the through hole 701 and threaded onto the pump body 1 and the pump cover 2. The fixing bolt 5 restricts the movement of the top plate 702, so that the top plate 702 cannot be separated from the top of the pump cover 2. Thus, the blocking effect of the top plate 702 prevents the pump cover 2 from moving away from the pump body 1.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
