Description

Technical Field

[0001] This utility model belongs to the field of optical lens technology, specifically a protective device for objective lenses of optical instruments. Background Technology

[0002] The objective lens is an important optical component in a microscope used to generate baseline magnification. It is usually composed of multiple lenses and its purpose is to overcome the imaging defects of a single lens and improve optical quality. The lenses are fixed inside the objective lens tube to form a complex optical system.

[0003] Existing objective lenses have complex structures and are manufactured with precision. They are usually composed of lens groups, with each lens spaced a certain distance from the others to reduce aberrations. Objective lenses are widely used in fields such as biological microscopy, industrial inspection, and materials science. However, during long-term use and observation, it has been found that because objective lenses are composed of a shell and lenses, and the existing objective lens shells lack protective structures, accidental drops during handling can cause the objective lens to directly impact the ground, easily damaging or breaking the lenses inside.

[0004] Therefore, this utility model provides a protective device for objective lenses used in optical instruments. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art and solve at least one of the problems mentioned in the background art, a protective device for objective lenses of optical instruments is proposed.

[0007] Preferably, the locking assembly includes a locking plate; the locking plate is hinged inside the fixing frame by a torsion spring; a sleeve is fitted onto the end of the optical lens body; a pair of slots are provided on the side wall of the sleeve; a sealing assembly is provided at the end of the sleeve; and a dehumidifying assembly is provided on the inner wall of the sleeve. With the above structure, by setting the locking plate, sleeve, and slots, the lens of the optical lens body can be protected by fixing the sleeve to the outside of the lens end of the optical lens body, thereby reducing the possibility of lens breakage caused by the lens impacting the ground when the optical lens body is dropped.

[0008] Preferably, the dehumidification component includes a tray; the tray is fixed to the side wall of the sealing component; a sealing cap is threaded to the top of the tray; the sealing cap has multiple vent holes on its top; and an anti-wear component is provided on the side wall of the sealing cap. With the above structure, the tray, sealing cap, and vent holes allow the desiccant in the tray to absorb moisture from the lens when the sleeve is wrapped around the outside of the optical lens body, thereby reducing the adhesion of moisture to the lens and preventing mold or water mist.

[0009] Preferably, the sealing assembly includes a cover plate; the cover plate is threadedly connected to the end of the sleeve; a knob is fixedly connected to the side wall of the cover plate; the knob has a cross-shaped structure; with the above structure, the cover plate and the knob are provided, and the threaded engagement between the cover plate and the sleeve makes it easy to remove the storage tray and the sealing cap from inside the sleeve, thereby improving the convenience of placing or replacing the desiccant in the storage tray.

[0010] Preferably, a fixing block is fixedly connected to the side wall of the card plate; an anti-slip pad is fixedly connected to the side wall of the fixing block; the fixing block is located near the end of the card plate. With the above structure, the fixing block and the anti-slip pad can improve the convenience of pressing the card plate, so as to reduce the situation where the fingers are blocked by the fixing frame after the card plate enters the fixing frame. At the same time, the anti-slip pad can increase the friction between the finger and the card plate, which can reduce the slippage during pressing and improve the stability of pressing the card plate.

[0011] Preferably, the anti-wear component includes a silicone ring; the silicone ring is fixed to the side wall of the sealing cover; the silicone ring has an annular structure; with the above structure, the silicone ring is connected to the sealing cover, and the silicone ring can contact the end of the optical lens body.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Specific implementation examples are given below.

[0024] like Figures 1 to 4As shown in the embodiment of this utility model, a protective device for an optical instrument objective lens includes an optical lens body 1; a pair of fixing frames 11 are fixedly connected to the side wall of the optical lens body 1; the pair of fixing frames 11 are symmetrical; a fixing plate 12 is fixedly connected to the side wall of the fixing frame 11; a pair of baffles 13 are fixedly connected to the side wall of the fixing plate 12; both the fixing plate 12 and the baffles 13 are made of elastic material; a locking assembly is installed inside the fixing frame 11; during operation, the locking assembly is connected to the fixing frame 11, and when the optical lens body 1 is accidentally dropped, the fixing assembly... The fixing plate 12 and the baffle 13 are located on the outside of the optical lens body 1. They can deform through their flexible material when impacted, thereby generating an energy absorption effect to reduce the impact force generated when the optical lens body 1 falls, thus protecting the optical lens body 1. Through the above structure, the fixing frame 11, the fixing plate 12 and the baffle 13 are set up to protect the outside of the optical lens body 1, thereby reducing the strong impact that may cause the optical lens body 1 to break and be damaged when it is accidentally dropped, thus improving the safety of the optical lens body 1 during use.

[0025] like Figure 1 and Figure 2 As shown, the locking assembly includes a locking plate 2; the locking plate 2 is hinged inside the fixed frame 11 by a torsion spring; a sleeve 21 is fitted onto the end of the optical lens body 1; a pair of slots 22 are formed on the side wall of the sleeve 21; a sealing assembly is provided at the end of the sleeve 21; a dehumidifying assembly is provided on the inner wall of the sleeve 21; during operation, the sleeve 21 is fitted onto one end of the lens of the optical lens body 1, and then the locking plate 2 is pressed to lift the end with the hook, aligning the slots 22 with the locking plate 2. Then, the pressing of the locking plate 2 is stopped, and under the rebound of the torsion spring, the hook of the locking plate 2 engages with the slot 22, thereby locking the sleeve 2... Position 1 is fixed on the outside of the optical lens body 1, thereby covering one end of the lens of the optical lens body 1. When the optical lens body 1 needs to be used, the locking plate 2 can be pressed again to make one end of the hook lift up, thereby releasing the fixation of the sleeve 21, and then the sleeve 21 can be removed from the outside of the optical lens body 1. Through the above structure, the locking plate 2, the sleeve 21 and the slot 22 are set. By fixing the sleeve 21 to the outside of the lens end of the optical lens body 1, the lens of the optical lens body 1 is protected, thereby reducing the possibility of the lens breaking when the optical lens body 1 is dropped and the lens impacts the ground.

[0026] like Figure 3As shown, the dehumidification assembly includes a tray 3; the tray 3 is fixedly connected to the side wall of the sealing assembly; a sealing cap 31 is threadedly connected to the top of the tray 3; the top of the sealing cap 31 has multiple ventilation holes 32; the side wall of the sealing cap 31 is provided with an anti-wear component; during operation, when the air is relatively humid, moisture adhering to the lens of the optical lens body 1 can cause mold or fogging. At this time, the top of the tray 3 can be opened by rotating the sealing cap 31, and then the desiccant can be placed into the tray 3, and then the sealing cap can be closed. The cover 31 is connected to the tray 3. When the sleeve 21 is fitted onto one end of the lens of the optical lens body 1, moisture in the air enters the sleeve 21 and enters the tray 3 through the vent 32. It is then absorbed by the desiccant inside the tray 3. Through the above structure, the tray 3, the sealing cover 31, and the vent 32 are configured so that when the sleeve 21 is wrapped around the outside of the lens of the optical lens body 1, the desiccant inside the tray 3 can absorb the moisture at the lens, thereby reducing the adhesion of moisture to the lens and preventing mold or water mist.

[0027] like Figure 3 As shown, the sealing assembly includes a cover plate 4; the cover plate 4 is threadedly connected to the end of the sleeve 21; a knob 41 is fixedly connected to the side wall of the cover plate 4; the knob 41 has a cross-shaped structure; during operation, when placing desiccant in the storage tray 3, the cover plate 4 can be removed or installed from the end of the sleeve 21 by rotating the knob 41 in either the forward or reverse direction. When the cover plate 4 is removed, the storage tray 3 and the sealing cover 31 installed on the side wall of the cover plate 4 can be taken out, which facilitates the placement or replacement of desiccant in the storage tray 3. Then, the cover plate 4 and the sleeve 21 are installed together. Through the above structure, the cover plate 4 and the knob 41 are set, and through the threaded engagement between the cover plate 4 and the sleeve 21, the storage tray 3 and the sealing cover 31 can be easily removed from the inside of the sleeve 21, thereby improving the convenience of placing or replacing desiccant in the storage tray 3.

[0028] like Figure 2 As shown, a fixing block 5 is fixedly connected to the side wall of the card plate 2; an anti-slip pad 51 is fixedly connected to the side wall of the fixing block 5; the fixing block 5 is located near the end of the card plate 2; during operation, when pressing the card plate 2, the finger can contact the anti-slip pad 51, and then pressing the fixing block 5 and the anti-slip pad 51 can cause the end of the card plate 2 to lift up. Through the above structure, the fixing block 5 and the anti-slip pad 51 can improve the convenience of pressing the card plate 2, so as to reduce the situation where the finger is blocked by the fixing frame 11 after the card plate 2 enters the fixing frame 11. At the same time, the anti-slip pad 51 can increase the friction between the finger and the card plate 2, which can reduce the slippage during pressing and improve the stability of pressing the card plate 2.

[0029] like Figure 3As shown, the anti-wear component includes a silicone ring 6; the silicone ring 6 is fixed to the side wall of the sealing cover 31; the silicone ring 6 has a ring structure; during operation, when the sleeve 21 is placed on the outside of the optical lens body 1, the silicone ring 6 will contact the end of the optical lens body 1. Through the above structure, the silicone ring 6 is connected to the sealing cover 31, and the silicone ring 6 can contact the end of the optical lens body 1. Moreover, its flexible material can reduce the wear caused by the long-term opening and closing of the sealing cover 31 and the end of the optical lens body 1.

[0030] like Figure 3 As shown, the sealing cover 31 has multiple anti-slip patterns 7 on its side wall; the multiple anti-slip patterns 7 are evenly distributed on the side wall of the sealing cover 31; during operation, when the sealing cover 31 is rotated to close or open from the top of the tray 3, the finger part will come into contact with the anti-slip patterns 7 on the side of the sealing cover 31. Through the above structure, the anti-slip patterns 7 can improve the friction between the finger part and the sealing cover 31 when the sealing cover 31 is rotated, thereby improving the stability when the sealing cover 31 is rotated.

[0031] Working principle: The locking assembly is connected to the fixing frame 11. When the optical lens body 1 is accidentally dropped, the fixing plate 12 and the baffle 13 are located on the outside of the optical lens body 1. Upon impact, their flexible material deforms, thereby generating an energy absorption effect to reduce the impact force generated when the optical lens body 1 falls, thus protecting the optical lens body 1. The sleeve 21 is placed on the lens end of the optical lens body 1, and then the locking plate 2 is pressed to make the end with the hook lift up, aligning the slot 22 with the locking plate 2, and then the pressing is stopped. Under the return force of the torsion spring, the latch 2 of the pressure plate 2 engages with the latch 22, thereby fixing the sleeve 21 to the outside of the optical lens body 1 and thus covering one end of the lens body 1. When the optical lens body 1 needs to be used, the pressure plate 2 can be pressed again to lift one end of the latch, thereby releasing the fixation of the sleeve 21, and then the sleeve 21 can be removed from the outside of the optical lens body 1. When the air is humid, moisture adhering to the lens of the optical lens body 1 can cause mold or fogging. In this case, by rotating... The sealing cap 31 opens the top of the storage tray 3, then the desiccant is placed inside the storage tray 3, and then the sealing cap 31 is connected to the storage tray 3. When the sleeve 21 is fitted onto the lens end of the optical lens body 1, moisture in the air enters the sleeve 21 and enters the storage tray 3 through the vent 32, where it is absorbed by the desiccant inside the storage tray 3. When placing the desiccant in the storage tray 3, the cover plate 4 can be removed or installed from the end of the sleeve 21 by rotating the knob 41 in either the forward or reverse direction. When removing the cover plate 4, the storage tray installed on the side wall of the cover plate 4 can be removed. Remove the tray 3 and sealing cover 31. This makes it easy to place or replace the desiccant in the tray 3. Then install the cover plate 4 and sleeve 21 together. When pressing the clamping plate 2, your fingers can contact the anti-slip pad 51. Then press the fixing block 5 and the anti-slip pad 51 to lift the end of the clamping plate 2. When the sleeve 21 is put on the outside of the optical lens body 1, the silicone ring 6 will contact the end of the optical lens body 1. When rotating the sealing cover 31 to close or open from the top of the tray 3, your fingers will contact the anti-slip texture 7 on the side of the sealing cover 31.
