Description

Technical Field

[0001] The invention relates to the technical field of a fixing device for a pump body, in particular to a fixing device for a vacuum pump. Background Art

[0002] A vacuum pump refers to a device or equipment that uses mechanical, physical, chemical or physicochemical methods to evacuate the container to obtain a vacuum. The vacuum pump needs to be fixed before working to avoid potential problems such as slipping during operation.

[0003] The patent with application number CN202320821850.2 discloses a fixing device for a vacuum pump, which relates to the field of installation protection. The fixing device for the vacuum pump includes an installation box and a vacuum pump, wherein a support plate is provided inside the installation box, a transmission block and a threaded rod are provided on one side of the support plate, a mounting block is fixedly connected to the bottom of the support plate, and a cross bar is fixedly connected inside the mounting block. The fixing device for the vacuum pump stops working when the support plate moves to the position for installing and disassembling the vacuum pump. At this time, the movable plate is aligned with the support groove provided in the installation box, so that the movable plate is pushed and moved by the spring, so that a part of the movable plate moves to the inside of the support groove. At this time, the movable plate is stuck between the installation box and the support plate, supporting the suspended support plate, avoiding the weight of the support plate, the concave base, the vacuum pump and other structures directly acting on the threaded rod during the installation and fixing of the vacuum pump, protecting the threaded rod, slowing down the wear rate of the threaded rod, and extending the service life of the threaded rod.

[0004] Based on the search of the above patents and the application of the existing vacuum pump fixing devices, it was found that when the current vacuum pump is in fixed use, the vibration force generated by itself will be transmitted to the fixed position, causing the fixed position to loosen, and even the fixed position of the vacuum pump to loosen and wear, affecting the service life of the vacuum pump. On the other hand, there will be a lot of noise during the use of the vacuum pump, which will interfere with nearby people.

[0008] Furthermore, the four hexagonal plugs arranged at the lower position of the connecting seat are respectively inserted into the four hexagonal grooves opened at the top position of the fixing seat, and each fixing bolt rod passes through the through holes of the two hexagonal plugs on the same side.

[0009] Furthermore, a protruding block is respectively provided on the left and right sides of the rear end of the mounting frame, and a threaded hole is respectively opened on the side of each protruding block. The threaded hole in the middle position of the protruding block on the left side of the mounting frame is rotatably connected with a first bolt, the right side position of the first bolt is rotatably connected to the left side position of the first sliding plate, and the front end position of the first sliding plate is slidably connected to the left side position of the rear end of the mounting frame.

[0010] Furthermore, a second bolt is rotatably connected to the threaded hole in the middle position of the raised block on the right side of the mounting frame. The second bolt is symmetrically designed to the first bolt. The left side of the second bolt is rotatably connected to the right side of the second sliding plate, and the front end of the second sliding plate is slidably connected to the right side of the rear end of the mounting frame.

[0011] Furthermore, the bottom position of the first sliding plate is fixedly connected to the top rear end position of the first clamping plate, the first clamping plate is located at the lower left position of the fixing seat, and the right side position of the first clamping plate is serrated.

[0014] Furthermore, the bottom position of the cover plate is fitted with the top position of the fixed seat, the vacuum pump body is located in the middle position of the cover plate, and the left and right sides of the cover plate are respectively fixedly connected with a docking plate, and the two docking plates are respectively fixedly connected to the left and right sides of the top of the fixed seat by bolts, a baffle is provided at the lower front end position of the cover plate, a circular through groove is opened at the middle and upper rear end position of the cover plate, and the exhaust fan is fixedly connected to the rear end position of the circular through groove of the cover plate; the internal position of the cover plate is a corrugated structure design, and a semi-conical groove is opened at the corrugated arc surface position of the cover plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. Insert the four hexagonal plugs into the four hexagonal slots at the top of the fixing seat, and then insert and rotate the two fixing bolts into the two threaded holes at the front end of the fixing seat. The fixing bolts on the same side will be located in the through holes of the two hexagonal plugs on the same side, and the whole connecting seat will be firmly fixed to the top of the fixing seat.

[0016] 2. During the operation of the vacuum pump body, the amplitude of the upper and lower positions will vibrate. The amplitude of the vibration of the vacuum pump body will be transmitted to the top position of the connecting seat, and the connecting seat will simultaneously drive the four covering frames to move up and down. At this time, the force of the vibration of the connecting seat is reduced by the cooperation of the telescopic rod and the spring part, which plays a buffering effect.

[0017] 3. When the vacuum pump body needs to be placed and fixed in the use position, the first bolt and the second bolt are rotated respectively. When the first bolt is rotated, the first bolt cooperates with the threaded hole of the raised block on the left side of the mounting frame to drive the first sliding plate to slide at the left position of the rear end of the mounting frame, thereby adjusting the position of the first clamping plate at the lower left of the fixed seat. When the second bolt is rotated, the second bolt cooperates with the threaded hole of the raised block on the right side of the mounting frame to drive the second sliding plate to slide at the right position of the rear end of the mounting frame to adjust the position of the second clamping plate at the lower right of the fixed seat. Then, the bottom position of the first clamping plate and the bottom position of the second clamping plate are supported to raise the height position of the fixed seat, and the position of the vacuum pump body can also be moved during the use of the vacuum pump body.

[0018] 4. When the position of the fixing seat needs to be fixed and limited to a specific position, the fixing point of the specific position is placed directly below the fixing seat, and then the first bolt and the second bolt are respectively rotated to make the distance between the first clamping plate and the second clamping plate closer, until the inner positions of the first clamping plate and the second clamping plate are clamped in the fixed position, and the position of the fixing device is limited and fixed. At the same time, combined with the serrated design of the first clamping plate and the second clamping plate, when the distance between the first clamping plate and the second clamping plate is fixed and clamped to a specific position, slipping is avoided and the fixed position is further stabilized.

[0019] 5. Put the cover plate on the outer side of the vacuum pump body, and then fix it on the left and right sides of the fixing seat through the cooperation of two docking plates and bolts. At this time, the noise generated by the vacuum pump body will be semi-blocked in the internal space of the cover plate. Combined with the corrugated arc surface design of the cover plate, the noise inside the cover plate will be reflected at irregular positions, reducing the sound while reflecting the sound and dispersing the sound distribution position. Combined with the semi-conical groove opened at the corrugated arc surface of the cover plate, the noise inside the cover plate can be further reduced to reduce the noise by half.
