Description

Technical Field

[0001] This utility model relates to the field of protection technology for optomechanical and optoelectronic devices, specifically a high-transmittance protective cover for optomechanical and optoelectronic devices. Background Technology

[0002] Opto-mechanical and optoelectronic devices, as key components in modern optics and optoelectronics, are extremely sensitive to environmental factors such as dust, moisture, impact, corrosive gases, and extreme temperature changes, all of which can affect their performance and lifespan. High-transmittance protective covers for opto-mechanical and optoelectronic devices provide a relatively stable and safe operating environment through physical protection, thereby ensuring the long-term reliable operation of the equipment. These covers are widely used in security monitoring, military, aerospace, and industrial inspection.

[0003] Existing protective covers are mostly fixed-height structures, and the light-transmitting windows of the cover cannot be adjusted with the height of the device, making it difficult to align the light path and causing light signal blockage or misalignment, which affects the detection accuracy.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a high-transmittance protective cover for optomechanical optoelectronic devices. Utility Model Content

[0005] The purpose of this invention is to provide a high-transmittance protective cover for optomechanical and optoelectronic devices to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-transmittance protective cover for optomechanical and optoelectronic devices, comprising a base and a cover body. A bearing is provided at a through hole in the middle of the left and right sides of the base, and a transmission shaft passes through the middle of the bearing. A turntable is fixed to the right end of the transmission shaft. A support plate is provided inside the upper part of the base, and a bearing is provided at a through hole on the surface of the support plate. A bevel gear 1 and a bevel gear 2 are sequentially arranged from right to left outside the transmission shaft, and a bevel gear 3 is provided outside both bevel gear 1 and bevel gear 2. A threaded rod passes through the middle of the bevel gear 3, and an adjusting column is threadedly connected to the outside of the threaded rod. A lifting seat is fixed outside the adjusting column. The cover body is located above the outer side of the base, and an electromagnetic shielding mesh is provided on the inner side of the cover body. A light-transmitting window is opened on the surface of the cover body.

[0007] Furthermore, a pin is inserted through the through hole on the surface of the turntable, and a retaining ring is fixed to the outer left side of the pin.

[0008] Furthermore, a compression spring is fitted around the outside of the pin, and the two ends of the compression spring are fixedly connected to the fixing ring and the turntable, respectively.

[0009] Furthermore, a limiting groove is provided on the right side of the base, and the limiting groove is distributed in a ring at equal intervals about the axis of the drive shaft. The size of the limiting groove is compatible with that of the pin.

[0010] Furthermore, there are two of each of the bearings, and the base and support plate are an integrated structure.

[0011] Furthermore, the drive shaft and the threaded rod are perpendicular to each other, and the threaded rod is perpendicularly inserted into the bearing.

[0012] Furthermore, there are two of each of the bevel gear, threaded rod, and adjusting column, and the adjusting columns are symmetrically distributed about the vertical central axis of the lifting seat.

[0013] Furthermore, the edges of the light-transmitting window are rounded, and the electromagnetic shielding mesh is pasted on the non-light-transmitting area around the inside of the cover.

[0014] This utility model provides a high-transmittance protective cover for optomechanical and optoelectronic devices, which has the following beneficial effects:

[0015] 1. This utility model utilizes the coordinated transmission of a drive shaft, bevel gear one, bevel gear two, bevel gear three, and a double threaded rod. Rotating the turntable drives the adjusting columns on both sides to rise and fall synchronously, causing the lifting seat and components to move smoothly. There is no unilateral offset during the adjustment process. The setting of bearing one and bearing two ensures smooth rotation of the drive shaft and threaded rod, avoiding height adjustment errors caused by jamming. It can accurately adapt to components with a height range of 20-80mm, solving the problem of poor adaptability of traditional fixed-height protective covers.

[0016] 2. The combination structure of the turntable, pin, compression spring, and limiting groove in this utility model achieves precise locking after height adjustment. Pulling the pin outward unlocks the adjustment, and the compression spring automatically resets after release, causing the pin to embed into the limiting groove. The ring-shaped and equidistantly distributed limiting grooves can adapt to different locking requirements for different adjustment heights. The mechanical locking effectively restricts the rotation of the drive shaft, avoids height deviation caused by vibration, and ensures that the device is always precisely aligned with the light-transmitting window under complex working conditions, thus ensuring the stability of optical signal transmission.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figures 1 to 3 As shown, a high-transmittance protective cover for optomechanical optoelectronic devices includes a base 1 and a cover body 17. Bearings 1-2 are installed at through holes in the middle of the left and right sides of the base 1, and a drive shaft 3 passes through the middle of the bearings 1-2. A turntable 4 is fixed to the right end of the drive shaft 3. A support plate 9 is installed on the upper part of the interior of the base 1, and bearings 2-10 are installed at through holes on the surface of the support plate 9. From right to left, bevel gears 1-11 and 2-12 are sequentially installed on the outside of the drive shaft 3, and bevel gears 3-13 are installed on the outside of both bevel gears 1-11 and 2-12. A threaded rod 14 passes through the middle of the bevel gear 3-13, and an adjusting column 15 is threadedly connected to the outside of the threaded rod 14. The external part of the 5 is fixed with a lifting seat 16. There are two bearings 1 and 2 bearings 10. The base 1 and the support plate 9 are integrated. The transmission shaft 3 and the threaded rod 14 are perpendicular to each other. The threaded rod 14 is perpendicularly inserted into the bearing 2 10. There are two bevel gears 13, two threaded rods 14 and two adjusting columns 15. The adjusting columns 15 are symmetrically distributed about the vertical central axis of the lifting seat 16. The cover 17 is located on the upper outer side of the base 1. The inner side of the cover 17 is provided with an electromagnetic shielding mesh 18. The surface of the cover 17 has a light-transmitting window 19 with rounded edges. The electromagnetic shielding mesh 18 is pasted on the non-light-transmitting area around the inner side of the cover 17.

[0023] The specific operation is as follows: through the coordinated transmission of drive shaft 3, bevel gear 11, bevel gear 2 12, bevel gear 3 13 and double threaded rod 14, rotating turntable 4 can drive the adjustment columns 15 on both sides to rise and fall synchronously, thereby driving the lifting seat 16 and the device to move smoothly. There is no unilateral deviation during the adjustment process. The setting of bearing 1 2 and bearing 2 10 ensures that drive shaft 3 and threaded rod 14 rotate smoothly, avoiding height adjustment errors caused by jamming. It can accurately adapt to devices with a height range of 20-80mm, solving the problem of poor adaptability of traditional fixed height protective covers.

[0024] like Figure 2As shown, a pin 5 passes through the through hole on the surface of the turntable 4, and a fixing ring 6 is fixed on the outer left side of the pin 5. A compression spring 7 is sleeved on the outside of the pin 5, and the two ends of the compression spring 7 are fixedly connected to the fixing ring 6 and the turntable 4 respectively. A limiting groove 8 is opened on the right side of the base 1, and the limiting groove 8 is distributed in a ring at equal intervals about the axis of the transmission shaft 3. The size of the limiting groove 8 and the pin 5 are compatible.

[0025] The specific operation is as follows: the cooperative structure of turntable 4 with pin 5, compression spring 7 and limiting groove 8 achieves precise locking after height adjustment. Pulling pin 5 outward can unlock the adjustment. After releasing, compression spring 7 automatically resets so that pin 5 is embedded in limiting groove 8. The ring-shaped and equidistantly distributed limiting grooves 8 can adapt to different locking requirements for different adjustment heights. The mechanical locking can effectively limit the rotation of drive shaft 3, avoid height deviation caused by vibration, and ensure that the device is always precisely aligned with the light-transmitting window 19 under complex working conditions, thus ensuring the stability of optical signal transmission.

[0026] In summary, the high-transmittance protective cover for this optomechanical optoelectronic device is made of high-hardness sapphire glass. The outer surface has an 80-100nm antireflection film to reduce external light reflection, and the inner surface has a 60-80nm antireflection film to reduce internal light signal reflection loss. The two work together to achieve a transmittance of ≥95%, ensuring efficient optical path transmission of the optomechanical optoelectronic device.

[0027] The optomechanical and optoelectronic devices are placed on the lifting base 16, and then the cover 17 is placed on the outside of the base 1 to form a closed protective space. When adjusting the height of the optomechanical and optoelectronic devices, the pin 5 is pulled outward to disengage it from the limiting groove 8. The turntable 4 is rotated to drive the transmission shaft 3 to rotate. The transmission shaft 3 is driven by the external bevel gear 11 and bevel gear 212, which mesh with the two bevel gears 33 respectively, converting the horizontal rotational motion into the vertical rotational motion of the threaded rod 14. The rotation of the threaded rod 14 drives the adjusting column 15 to rise and fall in the vertical direction, thereby driving the lifting base 16 and the devices above to rise and fall synchronously, so as to realize the adjustment of the device height.

[0028] When the device height is adjusted to align the light-transmitting window 19 with the light path, release the pin 5, and the compression spring 7 will return to its original position, pulling the fixing ring 6 and the pin 5 to the left, so that the pin 5 is inserted into the corresponding limiting groove 8. The mechanical engagement restricts the rotation of the transmission shaft 3, thereby locking the positions of the threaded rod 14, the adjusting column 15 and the lifting seat 16, ensuring the device height is stable and preventing height deviation due to vibration during use.

[0029] At this time, the electromagnetic shielding mesh 18 in the non-transparent area on the inner side of the cover 17 can isolate external electromagnetic radiation and prevent the circuit signals of the device from being disordered. The rounded corner design of the light-transmitting window 19 prevents stress concentration and scratches, and ensures efficient transmission of light signals. The fit between the base 1 and the cover 17 can block dust from entering. At the same time, the material of the cover 17 itself has impact resistance and wear resistance, providing a stable and safe operating environment for the device and ensuring long-term reliable operation.

[0030] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
