The lens cover is used to cover the lens of the corresponding lens, and the connecting ring is detachably sleeved on the outer peripheral surface of the corresponding lens. The connecting rod is elastic, allowing the corresponding lens cover to bend and rotate relative to the lens, and the connecting strap connects the connecting rings of the two lens cover assemblies to restrict the connecting rings of the two lens cover assemblies to the lens.

[0007] Furthermore, the connecting rod has a straight rod portion and a curved portion. One end of the straight rod portion is fixedly connected to the connecting ring, the other end of the straight rod portion is fixedly connected to one end of the curved portion, and the other end of the curved portion is fixedly connected to the lens cap.

[0008] Furthermore, the extension direction of the straight rod is perpendicular to the plane where the connecting ring is located.

[0009] Furthermore, the lens cap and the connecting ring are spaced apart, and the distance between the lens cap and the connecting ring corresponds to the length of the connecting rod.

[0010] Furthermore, the connecting strap is detachably connected to the connecting ring.

[0011] Furthermore, the outer wall of the connecting ring has an outwardly protruding portion, the protruding portion being provided with an insertion hole, and the two ends of the connecting band are respectively provided with buckles, the buckles being detachably fastened to the corresponding insertion holes.

[0012] Furthermore, the lens cap, the connecting ring, and the connecting rod are integrally formed.

[0013] This utility model provides a night vision device, which includes at least the aforementioned dual-lens protective cover.

[0014] The technical solution provided by this utility model has the following beneficial effects:

[0015] The lens cap is used to cover the lens of the corresponding lens to achieve effective protection of the lens. The connecting ring is detachably sleeved on the outer peripheral surface of the corresponding lens, and the connecting strap connects the connecting rings of the two lens cap assemblies to restrict the connecting rings of the two lens cap assemblies to the lens so that they are not easy to fall off or be lost. At the same time, the lens cap can also be bent or rotated significantly to improve the user experience. Attached Figure Description

[0019] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0020] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] Reference Figures 1 to 3 As shown, Embodiment 1 provides a dual-lens protective cover for protecting the dual lenses, such as the eyepiece 31 and objective lens 32, of the night vision device 3.

[0023] like Figure 1 and Figure 2As shown, the dual-lens protective cover of this embodiment includes two lens cover assemblies 1 and a connecting strip 2 connecting the two lens cover assemblies 1. Each lens cover assembly 1 includes a lens cover 11, a connecting ring 13 and a connecting rod 12 connecting the lens cover 11 and the connecting ring 13.

[0024] The lens cap 11 is used to cover the lens element of the corresponding lens to protect the lens from accidental scratches or the inhalation of external dust when the lens is not in use.

[0025] The connecting ring 13 is detachably sleeved on the outer peripheral surface of the corresponding lens. The connecting rod 12 is elastic, so that the corresponding lens cap 11 can be bent and rotated relative to the lens. The connecting strap 2 is connected between the connecting rings 13 of the two lens cap assemblies 1 to restrict the connecting rings 13 of the two lens cap assemblies 1 to the lens, so as to ensure that the distance between the connecting rings 13 of the two lens cap assemblies 1 is fixed. In this way, the connecting ring 13 on each side cannot be detached from the lens on the same side and is always sleeved on the corresponding lens, thereby avoiding the lens cap 11 from falling off or being lost.

[0026] In this embodiment, as Figure 2 As shown, the connecting rod 12 is made of elastic plastic, and each connecting rod 12 has a straight part 121 and a curved part 122. One end of the straight part 121 is fixedly connected to the corresponding connecting ring 13, and the other end of the straight part 121 is fixedly connected to one end of the corresponding curved part 122. The other end of the curved part 122 is fixedly connected to the corresponding lens cap 11, and the extension direction of the straight part 121 is perpendicular to the plane of the connecting ring 13. Of course, the lens cap 11 and the connecting ring 13 are spaced apart, and the distance between the lens cap 11 and the connecting ring 13 corresponds to the length of the connecting rod 12. When the connecting rod 12 is long enough, after the connecting ring 13 is fitted onto the lens, the movement space of the lens cap 11 is also increased to meet the usage habits of different users.

[0027] The lens cap 11 is used to cover the lens of the corresponding lens to achieve effective protection of the lens. The connecting ring 13 is detachably sleeved on the outer peripheral surface of the corresponding lens, and the connecting strap 2 connects the connecting ring 13 of the two lens cap assemblies 1 to restrict the connecting ring 13 of the two lens cap assemblies 1 to the lens so that it is not easy to fall off or be lost. At the same time, the lens cap 11 can also be bent or rotated significantly to improve the user experience.

[0028] In another preferred embodiment, the lens cap 11, connecting ring 13, and connecting rod 12 are integrally molded to simplify subsequent assembly processes. Of course, the lens cap 11 and connecting ring 13 are also made of elastic plastic.

[0029] In another preferred embodiment, the connecting band 2 is detachably connected to the connecting ring 13, and the outer wall of the connecting ring 13 has, for example, the connecting ring 13 has the following outer wall shape. Figure 2 The protruding part 131 shown is provided with an insertion hole 132. Both ends of the connecting strap 2 are provided with buckles. The buckles can be detachably fastened to the corresponding insertion hole 132 to facilitate the disassembly and assembly of each lens cover assembly 1.

[0030] like Figure 3 As shown, the night vision device 3 includes a night vision device body 33 and an eyepiece 31 and an objective lens 32 respectively connected to both ends of the night vision device body 33.

[0031] When needed, first, put the connecting ring 13 of one lens cap assembly 1 onto the pre-set groove on the outer circumferential surface of the eyepiece 31. Then, put the connecting ring 13 of the other lens cap assembly 1 onto the pre-set groove on the outer circumferential surface of the objective lens 32. After that, fasten the buckles at both ends of the connecting strap 2 into the corresponding insertion holes 132 of the connecting ring 13 to ensure that the connecting strap 2 and the two lens cap assemblies 1 are connected to form an integrated dual-lens protective cover, thereby enabling the entire dual-lens protective cover to be mounted on the night vision device 3.

[0032] Of course, in other embodiments, the positions of the jack 132 and the snap fastener can be interchanged, and are not limited to this.

[0033] Example 2

[0034] Embodiment 2 provides a night vision device, which includes at least the dual-lens protective cover of Embodiment 1.

[0035] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
