Description

Technical Field

[0001] This utility model relates to the field of optical technology, specifically to a sealing component, an optical device, and an optical equipment. Background Technology

[0002] Optical equipment includes optical components used to adjust light beams. By sealing the optical components in a housing, dust can be prevented from entering and causing contamination, and airflow can be prevented from interfering with the optical components.

[0003] In practical applications, adjustments to certain optical components may be necessary due to changes in the optical path or accumulation of errors. Opening the enclosure could lead to contamination of these components. The current mainstream solution involves creating a window in the enclosure and sealing it with a detachable cover. When adjustments are needed, the cover is removed, and after adjustment, it is reattached to the enclosure.

[0004] However, the disassembly and assembly of the enclosure with the cover plate is inconvenient and still does not improve the convenience of adjusting the optical components inside the enclosure. Utility Model Content

[0005] The purpose of this invention is to provide a sealing component, an optical device, and an optical equipment to solve the problem of inconvenience in adjusting optical components inside a housing.

[0006] To achieve the objectives of this utility model, the following technical solution is provided:

[0007] In a first aspect, this utility model provides a sealing assembly, comprising:

[0008] A sealing plate has a first hole, a locking groove and an unlocking groove. The sealing plate includes a first surface and a second surface that are opposite to each other. The first hole passes through the first surface and the second surface. The locking groove and the unlocking groove are recessed from the first surface and are spaced apart in a first direction.

[0009] A locking structure is disposed on one side of the first surface and is used to extend into the unlocking groove or the locking groove;

[0010] The sealing plate is movably mounted on the housing along the first direction, and the housing has a second hole; when the locking structure extends into the locking groove, the first hole and the second hole are offset, and the sealing plate closes the second hole; when the locking structure extends into the unlocking groove, the first hole and the second hole are aligned, and the aligned first hole and the second hole communicate between the interior and exterior of the housing.

[0011] In one embodiment, the inner wall of the unlocking groove includes an inclined wall, a supporting wall, and a blocking wall connected sequentially in a direction away from the locking groove. One end of the inclined wall away from the supporting wall is connected to the first surface, and one end of the blocking wall away from the supporting wall is connected to the first surface. The inclined wall is inclined relative to the first surface so that the locking structure can slide on the inclined wall. The blocking wall is used to contact the outer peripheral surface of the locking structure to prevent the sealing plate from continuing to move along the unlocking groove toward the locking groove.

[0012] In one embodiment, the angle between the inclined wall and the first surface is A, satisfying: 15°≤A≤60°.

[0013] In one embodiment, the locking structure includes a first elastic member and a locking pin. The first elastic member elastically presses against the locking pin in a second direction. The locking pin is used to extend into the unlocking groove or the locking groove. The second direction is perpendicular to the first direction.

[0014] In one embodiment, the bottom wall of the locking groove is provided with a first operating hole penetrating the second surface, wherein an external force is applied to the locking structure located in the locking groove through the first operating hole to cause the locking structure to retract from the locking groove.

[0015] In one embodiment, the bottom wall of the unlocking groove is provided with a second operating hole that penetrates the second surface, wherein an external force is applied to the locking structure located in the unlocking groove through the second operating hole to cause the locking structure to disengage from the unlocking groove.

[0016] In one embodiment, the sealing assembly further includes an ejector structure that elastically presses against the sealing plate in the first direction; wherein,

[0017] From the direction of the unlocking slot to the locking slot, the ejection structure releases elastic potential energy to move the sealing plate, thereby switching the locking structure from the state of being inserted into the locking slot to the state of being inserted into the unlocking slot;

[0018] An external force is applied to the sealing plate from the direction of the locking groove toward the unlocking groove to move the sealing plate. The sealing plate causes the locking structure to switch from being inserted into the unlocking groove to being inserted into the locking groove, and causes the ejection structure to accumulate elastic potential energy.

[0019] In one embodiment, the ejection structure includes a second elastic member and an ejection pin. The sealing plate has a guide groove extending in the first direction from one end of the unlocking groove away from the locking groove. The second elastic member is received in the guide groove and elastically abuts against the bottom wall of the guide groove. The ejection pin extends into the guide groove and abuts against the second elastic member.

[0020] Secondly, this utility model also provides an optical device, comprising:

[0021] The box has a receiving cavity, and a second hole is provided on the box to communicate with the receiving cavity;

[0022] Optical components are housed within the receiving cavity;

[0023] In any one of the various embodiments of the first aspect, the sealing assembly, wherein the sealing plate is movably disposed on the housing along a first direction, wherein when the locking structure extends into the locking groove, the first hole and the second hole are misaligned, and the sealing plate closes the second hole; and when the locking structure extends into the unlocking groove, the first hole and the second hole are aligned, and the aligned first hole and the second hole communicate with the receiving cavity and the outside.

[0024] In one embodiment, the box body has a receiving slot, and the box body also has a third operating hole that connects the receiving slot to the outside, and the sealing plate is received in the receiving slot;

[0025] When the locking structure extends into the locking groove, the third operating hole aligns with the first operating hole of the sealing plate, wherein an external force is applied to the locking structure located in the locking groove through the aligned first operating hole and the third operating hole, so as to cause the locking structure to exit the locking groove.

[0026] When the locking structure extends into the unlocking slot, the third operating hole aligns with the second operating hole of the sealing plate. Through the aligned second operating hole and the third operating hole, an external force is applied to the locking structure located in the unlocking slot to cause the locking structure to exit the unlocking slot.

[0027] In one embodiment, the housing has a receiving groove that communicates with the receiving slot, the locking structure is received in the receiving groove, and the third operating hole is aligned with the receiving groove.

[0028] Thirdly, the present invention also provides an optical device, including the optical apparatus described in any one of the various embodiments of the second aspect.

[0029] The sealing assembly provided by this utility model, by setting a sealing plate and a locking structure, has a first hole, a locking groove and an unlocking groove in the sealing plate. By moving the sealing plate along a first direction, the locking structure switches between being inserted into the unlocking groove and being inserted into the locking groove, so that the first hole can be misaligned or aligned with the second hole of the housing. When the first hole and the second hole are misaligned, the housing is sealed. When the first hole and the second hole are aligned, the inside of the housing is connected to the outside through the aligned first hole and the second hole. An adjustment tool can be used to adjust the optical components inside the housing through the first hole and the second hole. The operation is simple, there is no need to disassemble the housing, and the sealing plate will not fall off and be lost. Attached Figure Description

[0048] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or it can be in a middle component. When a component is said to be "connected" to another component, it can be directly connected to the other component or it may be in a middle component.

[0050] Unless otherwise defined, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used in this invention includes any and all combinations of one or more of the associated listed items.

[0051] In the embodiments of this application, "parallel" includes not only the case of absolute parallelism, but also the case of approximate parallelism as commonly understood in engineering; similarly, "perpendicular" also includes not only the case of absolute perpendicularity, but also the case of approximate perpendicularity as commonly understood in engineering. For example, if the angle between two directions is 85° to 90°, the two directions can be considered perpendicular; if the angle between two directions is 0° to 5°, the two directions can be considered parallel.

[0052] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0053] Please refer to Figure 1 This utility model provides an optical device 100, including a housing 10, optical components 20, and a sealing assembly 30.

[0054] The box 10 can be roughly rectangular and can be formed by splicing together multiple flat plates to form a receiving cavity 11 inside the box 10. Figure 1 To facilitate observation of the internal structure, the front plate of the box 10 shown is omitted. The box 10 has a second hole 12 that connects the receiving cavity 11 to the outside. The multiple plates of the box 10 form the bottom wall, top wall and four side walls of the box 10, and the second hole 12 can be opened on any one of these walls. Figure 1 The second hole 12 shown is opened on one of the side walls of the housing 10.

[0055] Optical device 20 is housed in housing cavity 11. Optical device 20 may include any feasible lens such as lens and reflector, as well as corresponding support structure. The support structure can be connected to housing 10 in any feasible manner, so that the lens is in a preset position and orientation.

[0056] The housing 10 is also provided with a light-inlet section 13 and a light-outlet section 14, which may be through holes or transparent structures. In a specific embodiment, refer to... Figure 1 The top wall of the housing 10 is provided with a light-inlet section 13, and one side wall of the housing 10 is provided with a light-outlet section 14. The side wall with the light-outlet section 14 and the side wall with the second hole 12 are opposite to each other. The optical device 20 includes a reflector. The light beam 200 enters the housing 10 from the light-inlet section 13 and is reflected on the reflector and emitted from the light-outlet section 14. Optionally, at least one plate of the housing 10 is a transparent component, which facilitates observation of the operating status of the internal optical device 20.

[0057] refer to Figures 2 to 4 The sealing assembly 30 includes a sealing plate 31 and a locking structure 32.

[0058] The sealing plate 31 can be generally a rectangular flat plate, and includes a first surface 311 and a second surface 312 that are opposite to each other in its thickness direction. The sealing plate 31 can be disposed on the flat plate of the housing 10 or inside the flat plate, the thickness direction of the sealing plate 31 is the same as the thickness direction of the flat plate, and the first surface 311 faces the interior of the housing 10.

[0059] Optional, see reference Figures 6 to 10 The flat plate of the housing 10 has a receiving groove 15, the opening of which can communicate with the outside. The sealing plate 31 can extend into the receiving groove 15 through the opening to install the sealing plate 31 onto the housing 10. The shape of the receiving groove 15 can be adapted to the shape of the sealing plate 31, so that the inner wall of the receiving groove 15 has a limiting effect on the sealing plate 31, so that the sealing plate 31 can only move along the first direction X and cannot move in other directions. For example, the receiving groove 15 is formed on the side wall of the housing 10, the opening of the receiving groove 15 is located on the bottom surface of the housing 10, the first direction X is the length direction of the sealing plate 31, and the first direction X is the direction of the bottom wall and the top wall of the housing 10 opposite each other. When the bottom surface of the housing 10 is placed on a horizontal plane, the first direction X is approximately vertical.

[0060] It is understandable that the sealing plate 31 can also be set on the bottom wall, top wall, etc. of the box 10, and the corresponding second hole 12 of the box 10 can also be opened on the bottom wall or top wall, etc., without restriction.

[0061] The sealing plate 31 has a first hole 313, a locking groove 314, and an unlocking groove 315. The first hole 313 penetrates through the first surface 311 and the second surface 312, and the shape of the first hole 313 can match the shape of the second hole 312. The locking groove 314 and the unlocking groove 315 are recessed from the first surface 311 and do not penetrate through the second surface 312. The locking groove 314 and the unlocking groove 315 are spaced apart in the first direction X.

[0062] The specific structure of the locking structure 32 is not limited. The locking structure 32 can be directly connected to the housing 10 or indirectly connected to the housing 10 through an intermediate structure. The locking structure 32 is disposed on one side of the first surface 311 and is used to extend into the unlocking groove 315 or the locking groove 314. The locking structure 32 is movable in the thickness direction of the sealing plate 31 to extend into or retract from the locking groove 314 and the unlocking groove 315.

[0063] Optional, see reference Figures 6 to 10The housing 10 has a receiving groove 16, which communicates with the receiving groove 15. The locking structure 32 is received in the receiving groove 16, and the shape of the receiving groove 16 can be adapted to the locking structure 32, so that the inner wall of the receiving groove 16 has a limiting effect on the locking structure 32, so that the locking structure 32 can only move along the second direction Y and cannot move in other directions. The second direction Y can be the thickness direction of the sealing plate 31, and the second direction Y can be perpendicular to the first direction X. For example, when the receiving groove 15 is provided on the side wall of the housing 10, and the opening of the receiving groove 15 is located on the bottom surface of the housing 10, the receiving groove 16 can be provided on the bottom wall of the housing 10.

[0064] The sealing plate 31 can move relative to the housing 10 along the first direction X, while the locking structure 32 cannot move in the first direction X. When the locking structure 32 extends into the locking groove 314, the locking structure 32 can fix the sealing plate 31 and prevent it from moving further in the first direction X; when the locking structure 32 exits the locking groove 314, the sealing plate 31 can move again along the first direction X until the locking structure 32 extends into the unlocking groove 315; when the locking structure 32 exits the unlocking groove 315, the sealing plate 31 can move in the opposite direction along the first direction X until the locking structure 32 re-enters the locking groove 314. In an embodiment where the sealing plate 31 is housed in the receiving groove 15 on the side wall of the housing 10 and the locking structure 32 is housed in the receiving groove 16 on the bottom wall of the housing 10, the locking groove 314 of the sealing plate 31 is closer to the bottom surface of the housing 10 than the unlocking groove 315. When the locking structure 32 exits from the locking groove 314, the sealing plate 31 can fall under the action of gravity until the locking structure 32 extends into the unlocking groove 315 and prevents the sealing plate 31 from falling further.

[0065] The sealing plate 31 can be moved along the first direction X to close the second hole 12, or the first hole 313 of the sealing plate 31 can be aligned with the second hole 12 of the housing 10. Specifically, when the locking structure 32 extends into the locking groove 314, the first hole 313 and the second hole 12 are misaligned, and the sealing plate 31 closes the second hole 12. In this way, the housing 10 is closed by the sealing plate 31, which can improve the sealing performance and prevent the optical components 20 inside the housing 10 from being contaminated by dust or interfered with by airflow. When the locking structure 32 extends into the unlocking groove 315, the first hole 313 and the second hole 12 are aligned. In this way, the receiving cavity 11 of the housing 10 communicates with the outside through the aligned first hole 313 and the second hole 12, and the optical components 20 can be adjusted by passing an adjustment tool through the first hole 313 and the second hole 12.

[0066] Optionally, the adjustment tool may include a first tool 40, which may be a rod-shaped component, such as a screwdriver, wrench, etc., for example. Figure 1 An embodiment of the first tool 40 being a hex wrench is shown.

[0067] The optical device 100 provided in this embodiment of the present invention employs a sealing component 30. The sealing component 30 is provided with a sealing plate 31 and a locking structure 32. The sealing plate 31 has a first hole 313, a locking groove 314, and an unlocking groove 315. By moving the sealing plate 31 along the first direction X, the locking structure 32 switches between being inserted into the unlocking groove 315 and being inserted into the locking groove 314, so that the first hole 313 can be misaligned or aligned with the second hole 12 of the housing 10. When the first hole 313 and the second hole 12 are misaligned, the housing 10 is sealed. When the first hole 313 and the second hole 12 are aligned, the interior of the housing 10 is connected to the outside through the aligned first hole 313 and the second hole 12. An adjustment tool can be used to adjust the optical device 20 inside the housing 10 through the first hole 313 and the second hole 12. The operation is simple, and there is no need to disassemble the housing 10. The sealing plate 31 will not fall off and be lost.

[0068] In one embodiment, reference Figures 2 to 4 The locking structure 32 includes a first elastic member 321 and a locking pin 322. The first elastic member 321 elastically presses against the locking pin 322 in the second direction Y, and the locking pin 322 is used to extend into the unlocking groove 315 or the locking groove 314.

[0069] The first elastic element 321 can be a spring, sheet metal, etc., capable of elastic deformation in the second direction Y and providing elastic tension along the second direction Y to push the locking pin 322 to move along the second direction Y. (Reference) Figures 6 to 10 In the embodiment where the locking structure 32 is housed in the receiving groove 16 on the bottom wall of the housing 10, the receiving groove 16 can be approximately a circular groove with its axial direction in the second direction Y. The locking pin 322 can be cylindrical, and the locking groove 314 can also be a circular groove. The first elastic element 321 is a spring, with one end elastically abutting against the bottom wall of the circular groove and the other end elastically abutting against the locking pin 322. The size of the locking pin 322 is adapted to the receiving groove 16, and the locking pin 322 is limited by the receiving groove 16 and can only move along the second direction Y.

[0070] The first elastic element 321 is always in a compressed state, so that the first elastic element 321 can always provide elastic tension so that the locking pin 322 tends to move toward the sealing plate 31. This allows the locking pin 322 to remain stable and not automatically withdraw when it is inserted into the locking groove 314 or the unlocking groove 315. After the locking pin 322 withdraws from the locking groove 314 under the action of external force, after the external force is removed, the locking pin 322 moves along the first direction X with the sealing plate 31 under the action of the first elastic element 321 and the unlocking groove 315 is aligned with the locking pin 322, and can automatically push the locking pin 322 into the unlocking groove 315.

[0071] Therefore, the first elastic element 321 is set to elastically press against the locking pin 322. Under the action of elastic tension, the locking pin 322 can stably maintain the state of being inserted into the unlocking groove 315 or the locking groove 314, so that the sealing plate 31 stably closes the second hole 12 or aligns the first hole 313 with the second hole 12, thereby improving reliability. When the locking pin 322 exits the locking groove 314 and the unlocking groove 315 is aligned with the locking pin 322, it can automatically spring back and extend into the unlocking groove 315, preventing the sealing plate 31 from falling out of the receiving groove 15, thus achieving partial automation and improving ease of use.

[0072] Optionally, the bottom wall of the locking groove 314 is provided with a first operating hole 316 penetrating the second surface 312. The diameter of the first operating hole 316 is smaller than that of the locking groove 314, so that after the locking pin 322 extends into the locking groove 314, it will press against the bottom wall of the locking groove 314 and will not extend into the first operating hole 316. Optionally, the first operating hole 316 is a circular hole, and the axis of the first operating hole 316 coincides with the axis of the locking groove 314, so that all circumferential positions of the locking pin 322 can contact the bottom wall of the locking groove 314, thus avoiding unstable pressing due to partial non-contact. The first operating hole 316 is used to remove the locking pin 322 from the locking groove 314. For example, an adjusting tool can be used to apply an external force to the locking pin 322 extending into the locking groove 314 through the first operating hole 316, and the locking pin 322 will be removed from the locking groove 314 under the action of the external force.

[0073] In one specific embodiment, reference Figures 2 to 4 , Figures 6 to 10 Taking the receiving groove 15 in which the sealing plate 31 is housed within the side wall of the housing 10 as an example, the side wall of the housing 10 is also provided with a third operating hole 17 that connects the receiving groove 15 to the outside. When the locking structure 32 extends into the locking groove 314, the third operating hole 17 is aligned with the first operating hole 316 of the sealing plate 31.

[0074] The adjustment tool may also include a second tool, which is used to pass through the aligned third operating hole 17 and the first operating hole 316 to apply an external force to the locking structure 32 extending into the locking groove 314, so as to remove the locking structure 32 from the locking groove 314, thereby releasing the state of the sealing plate 31 closing the second hole 12, and the sealing plate 31 can move along the first direction X.

[0075] Optionally, the first tool 40 and the second tool are the same, that is, they are both the same tool, such as a hex wrench. In this way, the functions of switching the sealing plate 31 to close the second hole 12 and expose the second hole 12 (that is, the first hole 313 and the second hole 12 are aligned) and adjusting the optical device 20 can be realized with one tool, without the need to provide two separate tools, thus improving the convenience of operation.

[0076] Optionally, the adjustment tool can be an accessory to the optical device. Alternatively, the adjustment tool can also be a non-accessory.

[0077] Optionally, the third operating hole 17 is aligned with the receiving groove 16. The shape and size of the third operating hole 17 can be adapted to the receiving groove 16, so that the locking structure 32 can be installed into the receiving groove 15 through the third operating hole 17 to realize the installation of the locking structure 32.

[0078] Optional, see reference Figures 2 to 4 The inner wall of the unlocking groove 315 includes an inclined wall 3151, a supporting wall 3152, and a blocking wall 3153 connected sequentially in a direction away from the locking groove 314. One end of the inclined wall 3151 away from the supporting wall 3152 is connected to the first surface 311, and one end of the blocking wall 3153 away from the supporting wall 3152 is also connected to the first surface 311. The inclined wall 3151 is inclined relative to the first surface 311 so that the locking pin 322 can slide on the inclined wall 3151. The blocking wall 3153 is used to contact the outer peripheral surface of the locking pin 322 to prevent the sealing plate 31 from continuing to move along the unlocking groove 315 towards the locking groove 314.

[0079] The inclined wall 3151, the supporting wall 3152, and the blocking wall 3153 can all be planar, as can the first surface 311. The transitions between adjacent surfaces are smooth. The supporting wall 3152 can be parallel to the first surface 311, and its dimension in the first direction X is not less than the diameter of the locking pin 322, ensuring that the end face of the locking pin 322 can fully contact the supporting wall 3152, guaranteeing stable insertion of the locking pin 322 into the unlocking groove 315. The blocking wall 3153 can be perpendicular to the first surface 311, allowing the locking pin 322 to contact the blocking wall 3153 at all positions along the depth direction of the unlocking groove 315, thus enhancing the blocking effect.

[0080] Optionally, the angle between the inclined wall 3151 and the first surface 311 is A, satisfying: 15°≤A≤60°. A can specifically be 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, etc. Within this angle range, the size of the inclined wall 3151 in the first direction X is moderate, allowing the locking pin 322 to slide on the inclined surface without easily getting stuck. If A < 15°, the size of the inclined wall 3151 in the first direction X is too large, resulting in an excessively long sealing plate 31, which cannot meet the requirements for installation into the housing 10. If A > 60°, the locking pin 322 is prone to jamming with the inclined wall 3151 and cannot slide, preventing the movement of the sealing plate 31 and thus preventing the switching between the closed and exposed states of the sealing plate 31 and the second hole 12.

[0081] Optional, see reference Figures 2 to 4The bottom wall of the unlocking groove 315 has a second operating hole 317 that penetrates the second surface 312. The diameter of the second operating hole 317 is smaller than that of the locking pin 322. When the locking pin 322 extends into the unlocking groove 315 and contacts the blocking wall 3153, the second operating hole 317 is aligned with the locking pin 322, and the locking pin 322 will not extend into the second operating hole 317. Optionally, the second operating hole 317 is formed on the supporting wall 3152.

[0082] In one specific embodiment, reference Figures 2 to 4 , Figures 6 to 10 Taking a case where the sealing plate 31 is housed in a receiving groove 15 within the side wall of the housing 10, and the side wall of the housing 10 has a third operating hole 17, when the locking structure 32 extends into the unlocking groove 315, the third operating hole 17 aligns with the second operating hole 317 of the sealing plate 31. A second tool can be used to pass through the aligned third and second operating holes 17 and 317 to apply external force to the locking structure 32 extending into the unlocking groove 315, thereby removing the locking structure 32 from the unlocking groove 315. In this embodiment, if it is necessary to replace parts, it may be necessary to remove the sealing plate 31 from the receiving groove 15. Therefore, a second tool can be used to push out the locking structure 32, so that the sealing plate 31 is no longer blocked by the blocking wall 3153 of the locking structure 32 on the unlocking groove 315, and can fall from the opening of the receiving groove 15. It should be understood that this step can be omitted when all components are working normally.

[0083] In one embodiment, reference Figures 2 to 4 The sealing assembly 30 also includes an ejector structure 33 that elastically presses against the sealing plate 31 in a first direction X, so that the sealing plate 31 tends to move relative to the locking structure 32 in the first direction X.

[0084] The ejector structure 33 has an elastic tension in the direction from the unlocking groove 315 to the locking groove 314. In the direction from the unlocking groove 315 to the locking groove 314, the ejector structure 33 releases elastic potential energy to move the sealing plate 31, thereby switching the locking structure 32 from the state of being inserted into the locking groove 314 to the state of being inserted into the unlocking groove 315. In the direction from the locking groove 314 to the unlocking groove 315, an external force is applied to the sealing plate 31 to move the sealing plate 31, thereby switching the locking structure 32 from the state of being inserted into the unlocking groove 315 to the state of being inserted into the locking groove 314, and causing the ejector structure 33 to accumulate elastic potential energy.

[0085] In one specific embodiment, reference Figures 2 to 4 , Figures 6 to 10Taking the sealing plate 31 housed in the receiving groove 15 within the side wall of the housing 10, with the opening of the receiving groove 15 facing downwards as an example, one end of the ejector structure 33 can abut against the top wall of the receiving groove 15 away from the opening, and the other end abuts against the sealing plate 31. When the locking structure 32 extends into the locking groove 314, the ejector structure 33 has elastic tension. When the locking structure 32 exits the locking groove 314, the ejector structure 33 releases elastic potential energy and generates elastic tension. Under the action of elastic tension and the weight of the sealing plate 31 itself, the sealing plate 31 moves towards the opening end of the receiving groove 15 until the locking structure 32 extends into the unlocking groove 315, thereby limiting the sealing plate 31. Therefore, by providing the ejector structure 33, a driving force can be applied to the sealing plate 31, making it easier to move the sealing plate 31 to switch between the closed and exposed states of the second hole 12.

[0086] In other embodiments, the first direction X can be set to other directions, such as the horizontal direction, or the push-out structure 33 can provide driving force to move the sealing plate 31.

[0087] Optionally, the ejector structure 33 is positioned to elastically press against the sealing plate 31 on the side of the unlocking groove 315 away from the locking groove 314. The ejector structure 33 can abut against one end face of the sealing plate 31 along its length, or a guide groove 318 extending in the first direction X can be provided on the end of the sealing plate 31 away from the unlocking groove 315 and the sealing plate 314, with the ejector structure 33 extending into the guide groove 318 and abutting against the bottom wall of the guide groove 318.

[0088] Optional, see reference Figures 2 to 4 The ejection structure 33 includes a second elastic member 331 and an ejection pin 332. The second elastic member 331 is received in the guide groove 318 and elastically abuts against the bottom wall of the guide groove 318. The ejection pin 332 extends into the guide groove 318 and abuts against the second elastic member 331.

[0089] The second elastic element 331 can be a spring, a sheet, etc., the ejector pin 332 can be a cylinder, and the guide groove 318 can also be circular. The second elastic element 331 is housed within the guide groove 318 and is limited, and can only undergo elastic deformation along the first direction X to generate elastic tension in the first direction X. The guide groove 318 extends into the guide groove 318 and is limited, and can only move along the first direction X. The provision of the second elastic element 331 and the ejector pin 332 can provide the driving force for the movement of the sealing plate 31, making it easier to switch the state of the sealing plate 31 closing or exposing the second hole 12. The structure is simple and the cost is low.

[0090] The end of the ejector pin 332 away from the second elastic member 331 is used to abut against the top wall of the receiving groove 15. When the locking structure 32 is in either the locking groove 314 or the unlocking groove 315, the ejector pin 332 can abut against the top wall of the receiving groove 15, and the second elastic member 331 can be in a compressed state, so that the sealing plate 31 tends to exit the receiving groove 15, thereby keeping the sealing plate 31 in contact with the locking structure 32 and maintaining structural stability. When the locking structure 32 exits the locking groove 314, under the elastic tension of the second elastic member 331, the sealing plate 31 moves until the locking structure 32 extends into the unlocking groove 315 and is tightly against the blocking wall 3153. When it is necessary to replace parts, the locking structure 32 can be removed from the unlocking groove 315, and under the elastic tension of the second elastic member 331, the sealing plate 31 can exit from the opening of the receiving groove 15.

[0091] The following describes the usage process of the sealing component 30 according to a specific embodiment.

[0092] Please refer to Figure 5 and combined Figures 2 to 4 The locking pin 322 is inserted into the locking groove 314. Figure 5 As shown in Figure a, the state after using the second tool to pass through the first operating hole 316 and lift the locking pin 322 is as follows. Figure 5 As shown in Figure b, under the elastic tension released by the elastic potential energy of the second elastic element 331, the sealing plate 31 is pushed to move, causing the locking pin 322 to be positioned between the locking groove 314 and the unlocking groove 315, as shown in Figure b. Figure 5 As shown in Figure C, the sealing plate 31 continues to move, and under the elastic tension of the first elastic element 321, it pushes the locking pin 322 into the unlocking groove 315 and into contact with the blocking wall 3153, as shown in Figure C. Figure 5 As shown in Figure d.

[0093] When a reset is required to allow the locking pin 322 to re-enter the locking groove 314, it can be done... Figure 5 Based on the state shown in Figure d, the operator applies an external force to the sealing plate 31 by hand or tool, causing the sealing plate 31 to move in the opposite direction of the first direction X. The first elastic element 321 and the second elastic element 331 are recompressed and accumulate elastic potential energy. The locking pin 322 slides over the inclined wall 3151 of the unlocking groove 315 and reaches... Figure 5 As shown in Figure c, continue pushing the sealing plate 31 until the locking pin 322 aligns with the unlocking slot 315 to achieve the desired state. Figure 5 As shown in Figure b, under the elastic tension of the first elastic element 321, the locking pin 322 is pushed into the locking groove 314 to achieve the desired state. Figure 5 As shown in Figure a, the reset is complete.

[0094] When parts need to be replaced, you can Figure 5Based on the state shown in Figure d, the second tool is used to pass through the second operating hole 317 and lift the locking pin 322. After the locking pin 322 is removed from the unlocking groove 315, it pushes the sealing plate 31 to move under the elastic tension of the second elastic element 331. Finally, the sealing plate 31 separates from the locking pin 322 and exits from the opening of the receiving groove 15, allowing for the replacement of parts.

[0095] Based on the usage of the sealing component 30, the usage of an optical device 100 according to a specific embodiment is described below.

[0096] refer to Figures 6 to 10 and combined Figures 1 to 5 ,like Figure 7 As shown, after the sealing assembly 30 is installed into the housing 10, when the optical component 20 does not require adjustment, the locking pin 322 is in the state of extending into the locking groove 314. At this time, the sealing plate 31 closes the second hole 12, which can prevent external dust, air, etc. from adversely affecting the optical component 20. When it is necessary to adjust the optical component 20, the second tool can be used to push out the locking pin 322 by passing through the third operating hole 17 and the first operating hole 316. The state of the locking pin 322 after exiting the locking groove 314 is as follows. Figure 8 As shown; under the weight of the sealing plate 31 itself and the elastic tension of the second elastic element 331, the sealing plate 31 is pushed downward, and the locking pin 322 is positioned between the locking groove 314 and the unlocking groove 315 as shown. Figure 9 As shown; the state when the locking pin 322 extends into the unlocking groove 315 and contacts the blocking wall 3153 is as follows Figure 10 As shown, at this time, the first hole 313 of the sealing plate 31 is aligned with the second hole 12 of the housing 10. The first tool 40 is used to pass through the first hole 313 and the second hole 12 to adjust the state of the optical device 20 inside the housing 10. Figure 1 As shown.

[0097] After adjusting the optical component 20, the second hole 12 needs to be resealed. This can be done manually or with a tool by applying external force to the sealing plate 31 to push it in the opposite direction (i.e., the locking groove 314 points towards the unlocking groove 315) until it moves as described above. Figure 7 The locking pin 322 is shown in the state where it re-extends into the locking groove 314. In this state, the ejector structure 33 re-accumulates elastic potential energy under the action of the sealing plate 31.

[0098] If parts need to be replaced, in such Figure 10 Based on the state shown, the second tool can be used to push the locking pin 322 out of the unlocking groove 315 through the third operating hole 17 and the second operating hole 317. Under the action of its own weight and the tension of the second elastic member 331, the sealing plate 31 falls from the opening of the receiving groove 15, and the ejecting pin 332 and the second elastic member 331 also fall down. The first elastic member 321 and the locking pin 322 can be taken out through the third operating hole 17.

[0099] When reinstalling the parts, the first elastic element 321 and the locking pin 322 can be inserted into the receiving groove 16 through the third operating hole 17, and the second elastic element 331 and the ejector pin 332 can be inserted into the guide groove 318. Then, the sealing plate 31 can be inserted into the receiving groove 15 through the opening of the receiving groove 15. The second tool can be used to push the locking pin 322 inward through the third operating hole 17 so that one end of the sealing plate 31 in the length direction can pass through. The first surface 311 of the sealing plate 31 can slide relative to the locking pin 322 until the locking pin 322 is aligned with the unlocking groove 315 and extends in. Due to the action of the blocking wall 3153, the sealing plate 31 will no longer fall out of the receiving groove 15 by itself. Continue to push the sealing plate 31 to move, and the locking pin 322 slides with the inclined wall 3151 and finally reaches the receiving groove 15. Figure 7 The locking pin 322 is shown in the state of being inserted into the locking groove 314, which completes the installation of the sealing plate 31 and achieves the closure of the second hole 12.
