Abstract
Description
Technical Field
[0001] This utility model relates to the field of laser gyroscope processing equipment technology, and in particular to a laser gyroscope vacuum exhaust platform. Background Technology
[0002] A laser gyroscope is a high-precision inertial navigation device based on the Sagnac effect. A vacuum degassing station is a specialized piece of equipment used for vacuuming, degassing, filling, sealing, and testing, and is widely used in laser gyroscopes, electron tubes, X-ray tubes, semiconductor devices, vacuum coating, and other fields. Its core function is to manufacture or process precision devices in a controlled vacuum environment.
[0003] Chinese Patent No. CN221792566U discloses an adjustable vacuum exhaust platform, including a device body containing a vacuum machine and a support base. The vacuum machine has a worktable at its upper end with several exhaust ports connected to it. Two sets of side slots are formed on both sides of the vacuum machine. An inner heat dissipation plate is slidably disposed within each side slot. An outer heat dissipation plate is fixed to the outside of the inner heat dissipation plate in the side slot. Several heat dissipation holes are formed on both the inner and outer heat dissipation plates. An upper rack is located at the center of the upper end of the inner heat dissipation plate. A gear is rotatably mounted on the upper end of the side slot, with its lower end meshing with the upper rack. This allows for misalignment adjustment between the two sets of heat dissipation plates, thereby achieving ventilation, heat dissipation, and misalignment sealing of the vacuum machine. It also improves the vacuum machine's buffering and vibration reduction capabilities, reducing vibration and wear between the vacuum machine and the ground, and enhancing the device's practicality.
[0004] However, the above technical solution has the following shortcomings: Although the vacuum exhaust platform can achieve ventilation and heat dissipation and misaligned sealing operation, the gears and racks need to be lubricated to reduce wear, but the lubricant will continue to evaporate, which may not only affect the main body of the equipment, but also require frequent maintenance, affecting the practicality of the heat dissipation structure. Utility Model Content
[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a laser gyroscope vacuum exhaust platform, which can not only control the opening and closing of the heat dissipation holes, but also eliminates the need for structures such as gears, racks, or repeated disassembly and reassembly of threaded fasteners, thus improving ease of use.

[0009] Preferably, the convex ring is provided with two symmetrically distributed guide sliders, and the frame is provided with grooves for the guide sliders to slide horizontally.
[0010] Preferably, a positioning seat is provided on the main body of the vacuum exhaust platform, and one end of the insertion rod is inserted into the interior of the positioning seat.

[0012] Preferably, the mounting frame is provided with four symmetrically distributed support blocks, and the vacuum exhaust table body is provided with rectangular grooves for the support blocks to be embedded in.
[0013] Preferably, a fixing bolt passes through and abuts against the support block, and the fixing bolt is threadedly connected to the main body of the vacuum exhaust table.
[0014] Compared with the prior art, the present invention has the following beneficial technical effects:
[0015] This utility model, through its rotating cover, rope, and connecting plate, enables ventilation and heat dissipation for the internal vacuum pump and circuitry of the vacuum exhaust platform. It also provides isolation and protection when the device is idle. The positioning mechanism helps to fix and limit the connecting plate, preventing the cover from being incompletely closed when closing the heat dissipation holes or from deflecting due to unexpected situations. Furthermore, it eliminates the need for gears, racks, or repeated disassembly and reassembly of threaded fasteners, making it simple, convenient, and highly practical. Attached Figure Description

Detailed Implementation
[0021] Example 1
[0022] like Figure 1 - Figure 4 As shown, the laser gyroscope vacuum exhaust platform proposed in this embodiment includes a vacuum exhaust 1. The vacuum exhaust platform body 1 is provided with a mounting frame 3. Multiple linearly distributed baffles 4 are rotatably connected to the mounting frame 3. Each baffle 4 is provided with a rope 5. A connecting plate 6 is provided on the rope 5. An elastic sealing gasket 17 is provided on the circumferential surface of the baffle 4.
[0023] The connecting pipe 2 is used to connect the pipeline to connect the vacuum exhaust platform body 1 and the laser gyroscope. When the cover plate 4 is flipped upward, a gap will appear between the adjacent cover plates 4, which is used to ventilate and dissipate heat to the internal vacuum pump and circuit equipment of the vacuum exhaust platform body 1. When the cover plate 4 is flipped downward, the adjacent cover plates 4 will contact each other in turn to close the gap, which is used for isolation and protection when the device is idle. The elastic sealing gasket 17 provided can improve the sealing effect of the edge of the cover plate 4 through elastic compensation. When the cover plate 4 is rotated, the connecting plate 6 can be pulled to drive the rope 5 to move, and then the rope 5 can drive all the cover plates 4 to rotate in the same direction.
[0024] The positioning mechanism includes a frame 8 mounted on the vacuum exhaust platform body 1, a rod 9 slidably connected to the frame 8, a convex ring 10 coaxially mounted on the rod 9, a spring 11 with its two ends respectively mounted on the convex ring 10 and the frame 8, a mounting block 7 with a positioning hole at the end of the connecting plate 6, and a pin 16 penetrating the frame 8 and the rod 9; the rod 9 has two through holes 15, the pin 16 passes through the through holes 15, the spring 11 is sleeved on the rod 9, the rod 9 passes through the positioning hole, the convex ring 10 has two symmetrically distributed guide sliders 13, and the frame 8 has a groove for the guide sliders 13 to slide horizontally.
[0025] The vacuum exhaust platform body 1 is provided with a positioning seat 14, one end of the insertion rod 9 is inserted into the interior of the positioning seat 14, and the end of the insertion rod 9 away from the positioning seat 14 is provided with a ball grip 12.
[0026] When the cover plate 4 is rotated via the connecting plate 6 to close the heat dissipation holes, the connecting plate 6 is first pulled to straighten the rope 5, and then the cover plate 4 is pulled downwards via the rope 5. When the mounting block 7 at the end of the connecting plate 6 contacts the outer surface of the vacuum exhaust platform body 1 and the cover plate 4 can no longer rotate, the cover plate 4 abuts in sequence, and then the pin 16 is pulled out from the through hole 15 near the end of the ball grip 12. Since the spring 11 is in a compressed state, after the restraining effect of the pin 16 is lost, the spring 11 pushes the convex ring 10 to cause the rod 9 to move. The sliding motion allows the insert rod 9 to pass through the positioning hole on the mounting block 7 and embed into the positioning seat 14, thereby fixing and limiting the connection plate 6. This prevents the cover plate 4 from not being fully closed when closing the heat dissipation hole or from tilting upwards due to unexpected situations. Finally, the pin 16 is inserted into the through hole 15 at the end away from the ball grip 12. This ensures the stability of the insert rod 9 and also serves to place the pin 16. This not only avoids the need to install gears, racks, or repeatedly disassemble and reassemble threaded fasteners, but also makes the operation simple and convenient, and has good practicality.
[0027] It should be noted that a mounting block 7 can also be installed on the top of the connecting plate 6, and a positioning mechanism (not shown) is also set above the mounting frame 3. When heat dissipation is performed, the connecting plate 6 is rotated by pulling the connecting plate 6 and the taut rope 5. When the positioning hole of the mounting block 7 on the top of the connecting plate 6 is aligned with the upper insertion rod 9, the pulling of the connecting plate 6 is stopped. At this time, the gap of the heat dissipation hole is the largest. Then, the insertion rod 9 limits the connecting plate 6 to prevent the cover plate 4 from failing to be in a stable open state after multiple rotations and thus flipping downwards.
[0028] Example 2
[0029] like Figure 1 and Figure 2 As shown, in this embodiment, a laser gyroscope vacuum exhaust platform is provided. Compared with the first embodiment, in this embodiment, the mounting frame 3 is provided with four symmetrically distributed support blocks 18, the vacuum exhaust platform body 1 is provided with a rectangular groove for the support blocks 18 to be embedded, and a fixing bolt 19 is passed through and abutted on the support block 18. The fixing bolt 19 is threadedly connected to the vacuum exhaust platform body 1.
[0030] The mounting frame 3 is positioned on the vacuum exhaust platform body 1 by the support block 18 and the rectangular groove. The support block 18 and the mounting frame 3 are then fixedly installed with the fixing bolts 19 to realize the installation of the heat dissipation structure. The operation is simple.
[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
