[0032] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0033] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application.

The words “comprising” or “including” and similar terms mean that the element or object preceding “comprising” or “including” covers the element or object listed following “comprising” or “including” and its equivalents, and does not exclude other elements or objects. The words “connected” or “linked” and similar terms are not limited to physical or mechanical connections and can include electrical connections, whether direct or indirect. The singular forms “a,” “the,” and “the” used in this application specification and appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0035] like Figure 1-3 As shown, a multi-array lens group of 4 includes a base 1, a first sleeve 2 detachably connected to the base 1, and a second sleeve 3 detachably connected to the base 1. Multiple detachable lenses 4 are disposed on the base 1. Fixed lenses 4 are disposed in the first sleeve 2 and the second sleeve 3. The outer surface of the base 1 is provided with a first external thread 101 and a second external thread 102. The inner surface of the first sleeve 2 is provided with a first internal thread 201 adapted to the first external thread 101. The inner surface of the second sleeve 3 is provided with a second internal thread 301 adapted to the second external thread 102. The first sleeve 2 and the second sleeve 3 are detachably connected to the base 1 through the engagement of the internal and external threads. The threaded connection method has advantages such as detachability, reliability, and economy.

[0036] In this embodiment, the base 1 includes a first component 103 and a second component 104 that are detachably connected to and adapted to the first component 103. The inner surface of the first component 103 is provided with a third internal thread 105, and the outer surface of the second component 104 is provided with a third external internal thread adapted to the third internal thread 105. The first component 103 and the second component 104 are detachably connected by the cooperation of the internal and external threads. The threaded connection method has the advantages of detachability, reliability and economy.

[0037] In this embodiment, the first external thread 101 is located on the outer surface of the first component 103, and the second external thread 102 is located on the outer surface of the second component 104.

[0038] In this embodiment, the first external thread 101 and the second external thread 102 are opposite threads to each other. The opposite threads can isolate the first sleeve 2 and the second sleeve 3, preventing the first sleeve 2 and the second sleeve 3 from rotating excessively. If the first external thread 101 is a left-hand thread, then the second external thread 102 is a right-hand thread; if the first external thread 101 is a right-hand thread, then the second external thread 102 is a left-hand thread.

[0039] In this embodiment, a partition 107 is provided between the first external thread 101 and the second external thread 102. The partition 107 separates the first external thread 101 and the second external thread to prevent the first sleeve 2 and the second sleeve 3 from rotating excessively. The partition 107 is preferably located on the first component 103, but it can also be located on the second component 104, or on the first component 103 and the second component 104.

[0040] In this embodiment, mounting rings 5 ​​are provided on the first component 103, the second component 104, the first sleeve 2 and the second sleeve 3, and the lens 4 is installed in the mounting rings 5 ​​and fixed by the mounting rings 5.

[0041] Specifically, the base 1 is provided with three lenses 4. One lens 4 is located between the mounting ring 5 at the top of the first component 103 and the mounting ring 5 at the bottom of the first sleeve 2, and is pressed and fixed by the two mounting rings 5; one lens 4 is located between the mounting ring 5 at the bottom of the first component 103 and the mounting ring 5 at the top of the second component 104, and is pressed and fixed by the mounting ring 5; one lens 4 is located between the mounting ring 5 at the bottom of the second component 104 and the mounting ring 5 at the top of the first sleeve 2, and is pressed and fixed by the mounting ring 5.

[0042] In this embodiment, the outer surfaces of the first sleeve 2 and the second sleeve 3 are provided with a plurality of equally spaced grooves 6 arranged along the length direction of the first sleeve 2 and the second sleeve 3. In this way, the grooves 6 increase the contact area between the hand and the outer surfaces of the first sleeve 2 and the second sleeve 3, and increase the friction between the hand and the outer surfaces of the first sleeve 2 and the second sleeve 3, which facilitates the installation or removal of the first sleeve 2 and the second sleeve 3.

[0043] In this embodiment, the multi-array lens group has a total of five lenses 4. The lenses 4 on the base 1 can be replaced by disassembly, and the lenses 4 on the first sleeve 2 and the second sleeve 3 can be replaced directly by disassembling the sleeve.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
