Description

Technical Field

[0001] The invention belongs to the technical field of telescopes, in particular to a waterproof and fog-proof camping telescope. Background Art

[0002] Camping binoculars are portable optical instruments designed for outdoor activities, mainly used to observe distant scenery, plants, animals or terrain. It combines lightness, durability and high-performance optical design, suitable for use in outdoor scenes such as camping, hiking, bird watching, hunting, etc. Due to the different use environments of camping binoculars, higher requirements are placed on the binoculars.

[0003] Due to the complex outdoor environment, when the temperature is low in the wild, a certain amount of fog will appear on the lens of the telescope, resulting in blurred images. Due to the coating on the objective lens, manual wiping will cause the lens to become blurred, affecting the imaging effect. Since it is difficult to find a suitable lens wiping cloth outdoors, it is difficult to clean the fog in time.

[0004] At the same time, due to the complex outdoor environment, there is a lot of dust and sand in the air. When not in use, there is a possibility that dust or sand will enter the lens surface, causing irreversible damage to the lens coating, which urgently needs improvement. Summary of the invention

[0005] The object of the present invention is to provide a waterproof and fog-proof camping telescope to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a waterproof and fog-proof camping telescope, comprising a waterproof shell, an adjusting roller movably installed in the middle of the waterproof shell, objective lenses are inlaid and installed on the left and right sides of the front of the waterproof shell, eyepieces are inlaid and installed on the left and right sides of the back of the waterproof shell, cover plates are provided on the left and right sides of the front of the waterproof shell, longitudinal guide rails are installed on the left and right sides of the waterproof shell close to the front, a connecting frame is installed between the two cover plates, a clamping block is installed on the relatively distant side of the two cover plates, the cover plate is movably clamped with the longitudinal guide rail through the clamping block, the cover plate moves up and down relative to the longitudinal guide rail, a power assembly is movably installed on the front of the connecting frame, an extension frame is installed in the middle of the front of the two cover plates, a self-cleaning assembly is movably sleeved inside the extension frame, and the front of the self-cleaning assembly is connected to the left and right sides of the power assembly.

[0007] The interior of the waterproof shell, that is, between the objective lens and the eyepiece, is filled with a protective gas, namely nitrogen, which is used to prevent fogging inside the objective lens and the eyepiece lenses. The focal length can be adjusted by adjusting the roller. In the use state, both cover plates are located above the front of the waterproof shell and do not block the objective lens. At this time, the outside world can be observed through the objective lens.

[0008] As a further technical solution of the present invention, the power assembly includes an extension shaft, which is movably connected to the middle of the connecting frame, and the extension shaft rotates relative to the connecting frame. A driving gear is fixedly installed on the front side of the extension shaft.

[0009] As a further technical solution of the present invention, the power assembly further comprises driven gears arranged on the front sides of the two cover plates, and relatively close ends of the two driven gears are meshedly connected with the driving gears.

[0010] As a further technical solution of the present invention, an operating wheel is installed in the middle of the front side of the driving gear, and an anti-slip groove is provided on the outer surface of the operating wheel.

[0011] When the surface of the objective lens is fogged due to excessive ambient temperature difference, the connecting frame can be pressed down to make the two cover plates drop synchronously until the two cover plates just cover the left and right sides of the front of the waterproof shell, that is, the objective lens is completely blocked. At this time, the power assembly and the self-cleaning assembly have arrived at the specified positions, and the self-cleaning assembly is located just in the middle position directly in front of the objective lens.

[0012] As a further technical solution of the present invention, the self-cleaning component includes an air storage pipe, the outer side surface of the air storage pipe is movably connected to the extension frame, the inside of the air storage pipe is movably connected to a piston plate, the front end of the piston plate is fixedly mounted with a piston rod, and the front end of the piston rod passes through the front end of the air storage pipe.

[0013] As a further technical solution of the present invention, the outer side surface of the air storage pipe is fixedly connected to the middle part of the driven gear, the air storage pipe rotates with the driven gear, and the end of the piston rod close to the cover plate is fixedly installed with a push rod located inside the air storage pipe, and the end of the push rod away from the piston plate passes through the air storage pipe and one side of the cover plate in sequence.

[0014] As a further technical solution of the present invention, a rubber brush is fixedly installed on the side of the push rod away from the piston plate, and the rubber brush is located on the inner side of the cover plate. A return spring is movably sleeved on the outer side of the piston rod, and the left and right ends of the return spring are respectively connected to one end of the inner cavity of the air storage tube and one end of the piston plate.

[0015] When removing fog, the driving gear can be driven to rotate by turning the operating wheel, and the driven gears on both sides of the driving gear will rotate accordingly, that is, the two driven gears rotate synchronously, and the gas storage tube on the inner side can rotate synchronously, and the gas storage tube can synchronously drive the internal push rod to rotate, and the two piston rods are pressed inward at the same time, that is, the piston rod and the push rod are kept displaced toward the objective lens until the inner side of the rubber brush contacts the objective lens, and the rotation of the push rod can synchronously drive the rubber brush to rotate, and the rubber brush can rotate circumferentially relative to the surface of the objective lens to complete the self-cleaning process of the surface fog.

[0016] By utilizing the cooperation between the power component and the self-cleaning component, that is, by adjusting the self-cleaning component to a predetermined position and operating the power component, the surface of the objective lens can be automatically cleaned. The whole process can be completed quickly, and the surface of the objective lens can be quickly self-cleaned without touching the objective lens with hands. At the same time, it can be quickly switched to the working state after cleaning, which significantly improves the imaging quality in harsh environments and is suitable for use in camping environments.

[0017] As a further technical solution of the present invention, the two gas storage pipes are fixedly connected to an intake valve at one end close to the cover plate and away from each other, and the two gas storage pipes are fixedly connected to an exhaust valve at one end close to the cover plate and close to each other, and the other end of the exhaust valve is connected to the interior of the cover plate.

[0018] As a further technical solution of the present invention, the intake valve and the exhaust valve are both one-way valves, and the valve directions are respectively inwardly open and outwardly closed, and outwardly open and inwardly closed. When the reset spring is in an extreme tensile state, the inner side of the rubber brush contacts the surface of the objective lens.

[0019] At the same time, when the device is not in use and is in a cleaning state, that is, when the cover plate completely blocks the surface of the objective lens, when the surface of the objective lens is cleaned, the piston rod moves beyond the objective lens, and the reset spring is stretched accordingly. At this time, the piston plate can be displaced in a direction close to the objective lens. At this time, the air inside the gas storage tube can be discharged through the exhaust valve and directly act on the surface of the objective lens to complete automatic dust removal. When the reset spring is automatically reset, the piston plate can be displaced in a direction away from the objective lens, and negative pressure is generated inside the gas storage tube, so that external air is sucked into the gas storage tube for temporary storage, waiting for the next use.

[0020] The automatic cleaning process of the objective lens surface is reused through the self-cleaning component. That is, when the device is automatically cleaning, the air is automatically discharged and the objective lens surface is automatically cleaned. When the self-cleaning component is automatically reset, the air is automatically replenished. The whole process can be completed automatically, which can effectively reduce the dust on the objective lens surface, reduce the possibility of sand or dust entering the objective lens surface, and increase the coating life of the objective lens surface. It is suitable for use in harsh environments.

[0021] The beneficial effects of the present invention are as follows: (1) The present invention utilizes the cooperation between the power component and the self-cleaning component, that is, by adjusting the self-cleaning component to a predetermined position and operating the power component, the surface of the objective lens can be automatically cleaned.

At the same time, it can be quickly switched to the working state after cleaning, which significantly improves the imaging quality in harsh environments and is suitable for use in camping environments.

[0022] (2) The present invention reuses the automatic cleaning process of the objective lens surface through the self-cleaning component, that is, when the device is automatically cleaning, the air is automatically discharged and the objective lens surface is automatically cleaned. When the self-cleaning component is automatically reset, the air can be automatically replenished. The whole process can be completed automatically, which can effectively reduce the dust on the objective lens surface, reduce the possibility of sand or dust entering the objective lens surface, and increase the coating life of the objective lens surface. It is suitable for use in harsh environments. BRIEF DESCRIPTION OF THE DRAWINGS

A power component 9 is movably installed on the front of the connecting frame 6, and an extension frame 10 is installed in the middle of the front of the two cover plates 5. The extension frame 10 is movably sleeved with a self-cleaning component 11 inside, and the front of the self-cleaning component 11 is connected to the left and right sides of the power component 9.

[0027] The interior of the waterproof housing 1, i.e., between the objective lens 3 and the eyepiece 4, is filled with a protective gas, i.e., nitrogen, for preventing fogging from occurring inside the objective lens 3 and the eyepiece 4. The focal length can be adjusted by adjusting the roller 2. In the use state, both cover plates 5 are located above the front of the waterproof housing 1 and do not block the objective lens 3. At this time, the outside world can be observed through the objective lens 3.

[0028] like Figure 2 and Figure 4 as well as Figure 5As shown, the power assembly 9 includes an extension shaft 901, which is movably connected to the middle part of the connecting frame 6, and the extension shaft 901 rotates relative to the connecting frame 6. A driving gear 902 is fixedly installed on the front side of the extension shaft 901. The power assembly 9 also includes a driven gear 903 arranged on the front sides of the two cover plates 5. The relatively close ends of the two driven gears 903 are meshed and connected with the driving gear 902. An operating wheel 904 is installed in the middle of the front side of the driving gear 902, and an anti-slip groove is provided on the outer surface of the operating wheel 904.

[0029] When the surface of the objective lens 3 is fogged due to a large ambient temperature difference, the connecting frame 6 can be pressed downward to make the two cover plates 5 descend synchronously until the two cover plates 5 just cover the left and right sides of the front of the waterproof housing 1, that is, the objective lens 3 is completely blocked. At this time, the power component 9 and the self-cleaning component 11 both arrive at the specified positions, and the self-cleaning component 11 is located in the middle position just in front of the objective lens 3.

[0030] like Figure 1 and Figure 2 as well as Figure 6 and Figure 7 As shown, the self-cleaning assembly 11 includes an air storage pipe 111, the outer side of the air storage pipe 111 is movably sleeved with the extension frame 10, the interior of the air storage pipe 111 is movably sleeved with a piston plate 113, the front end of the piston plate 113 is fixedly mounted with a piston rod 112, the front end of the piston rod 112 passes through the front end of the air storage pipe 111, the outer side of the air storage pipe 111 is fixedly sleeved with the middle part of the driven gear 903, the air storage pipe 111 rotates with the driven gear 903, and the end of the piston rod 112 close to the cover plate 5 A push rod 114 is fixedly installed inside the gas storage pipe 111, and the end of the push rod 114 away from the piston plate 113 passes through the gas storage pipe 111 and one side of the cover plate 5 in sequence. A rubber brush 115 is fixedly installed on the side of the push rod 114 away from the piston plate 113, and the rubber brush 115 is located on the inner side of the cover plate 5. A return spring 116 is movably sleeved on the outer side of the piston rod 112, and the left and right ends of the return spring 116 are respectively connected to one end of the inner cavity of the gas storage pipe 111 and one end of the piston plate 113.

[0031] Embodiment: When removing fog, the driving gear 902 can be driven to rotate by rotating the operating wheel 904, and the driven gears 903 on both sides of the driving gear 902 rotate accordingly, that is, the two driven gears 903 rotate synchronously, and the gas storage tube 111 on the inner side can rotate synchronously. At this time, the gas storage tube 111 can synchronously drive the internal push rod 114 to rotate, and at this time, the two piston rods 112 are pressed inward at the same time, that is, the piston rod 112 and the push rod 114 are kept displaced toward the objective lens 3 until the inner side of the rubber brush 115 is in contact with the objective lens 3. At this time, the rotation of the push rod 114 can synchronously drive the rubber brush 115 to rotate, and at this time, the rubber brush 115 can rotate circumferentially relative to the surface of the objective lens 3 to complete the self-cleaning process of the surface fog.

[0032] By utilizing the cooperation between the power component 9 and the self-cleaning component 11, that is, by adjusting the self-cleaning component 11 to a predetermined position and operating the power component 9, the surface of the objective lens 3 can be automatically cleaned. The whole process can be completed quickly, and there is no need to touch the objective lens 3 with hands. The surface of the objective lens 3 can be quickly self-cleaned. At the same time, it can be quickly switched to the working state after cleaning, which significantly improves the imaging quality in harsh environments and is suitable for use in camping environments.

[0033] like Figure 7 As shown, the two gas storage tubes 111 are fixedly connected with an intake valve 117 at one end close to the cover plate 5 and away from each other, and the two gas storage tubes 111 are fixedly connected with an exhaust valve 118 at one end close to the cover plate 5 and away from each other. The other end of the exhaust valve 118 is connected to the inside of the cover plate 5. The intake valve 117 and the exhaust valve 118 are both one-way valves, and the valve directions are inward conduction and outward blockage, and outward conduction and inward blockage, respectively. When the reset spring 116 is in the extreme tension state, the inner side of the rubber brush 115 contacts the surface of the objective lens 3.

[0034] Embodiment: When the device is not in use and is in a cleaning state, that is, when the cover plate 5 completely blocks the surface of the objective lens 3, and when the surface of the objective lens 3 is being cleaned, the piston rod 112 is displaced beyond the objective lens 3, and the reset spring 116 is stretched accordingly. At this time, the piston plate 113 can be displaced in a direction close to the objective lens 3. At this time, the air inside the gas storage tube 111 can be guided out through the exhaust valve 118 and directly act on the surface of the objective lens 3 to complete automatic dust removal. When the reset spring 116 is automatically reset, the piston plate 113 can be displaced in a direction away from the objective lens 3, and negative pressure is generated inside the gas storage tube 111, and external air is sucked into the gas storage tube 111 for temporary storage, waiting for the next use.

[0035] The self-cleaning component 11 is used to reuse the automatic cleaning process of the surface of the objective lens 3, that is, when the device is automatically cleaned, the air is automatically discharged and the surface of the objective lens 3 is automatically cleaned. When the self-cleaning component 11 is automatically reset, the air can be automatically replenished. The whole process can be completed automatically, which can effectively reduce the dust on the surface of the objective lens 3, reduce the possibility of sand or dust entering the surface of the objective lens 3, and increase the coating life of the surface of the objective lens 3. It is suitable for use in harsh environments.

[0036] Working principle and usage process: When the surface of the objective lens 3 is fogged due to a large temperature difference in the environment, the connecting frame 6 can be pressed downward to make the two cover plates 5 descend synchronously until the two cover plates 5 just cover the left and right sides of the front of the waterproof housing 1, that is, the objective lens 3 is completely blocked. At this time, the power component 9 and the self-cleaning component 11 both reach the specified position, and the self-cleaning component 11 is just located in the middle position in front of the objective lens 3; When removing the mist, the driving gear 902 can be driven to rotate by rotating the operating wheel 904, and the driven gears 903 on both sides of the driving gear 902 rotate accordingly, that is, the two driven gears 903 rotate synchronously, and the gas storage tube 111 on the inner side can rotate synchronously, and the gas storage tube 111 can synchronously drive the internal push rod 114 to rotate, and at this time, the two piston rods 112 are pressed inward at the same time, that is, the piston rod 112 and the push rod 114 are kept to move toward the objective lens 3 until the inner side of the rubber brush 115 is in contact with the objective lens 3. At this time, the rotation of the push rod 114 can synchronously drive the rubber brush 115 to rotate, and the rubber brush 115 can rotate circumferentially relative to the surface of the objective lens 3, completing the self-cleaning process of the surface mist; At the same time, when the device is not in use and is in a cleaning state, that is, when the cover plate 5 completely blocks the surface of the objective lens 3, and when the surface of the objective lens 3 is being cleaned, the piston rod 112 is displaced beyond the objective lens 3, and the reset spring 116 is stretched accordingly. At this time, the piston plate 113 can be displaced in a direction close to the objective lens 3. At this time, the air inside the gas storage tube 111 can be discharged through the exhaust valve 118 and directly act on the surface of the objective lens 3 to complete automatic dust removal. When the reset spring 116 is automatically reset, the piston plate 113 can be displaced in a direction away from the objective lens 3, and negative pressure is generated inside the gas storage tube 111, so that external air is sucked into the gas storage tube 111 for temporary storage, waiting for the next use.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
