Title: Combined Structure of Waterproof Lens and Camera for Monitoring Purpose

Description:
BACKGROUND OF INVENTION 
     1. Field of the Invention 
     The present invention relates generally to a waterproof lens and a waterproof camera, and more particularly to a combined structure which enables rapid and simple assembly or disassembly of the waterproof lens and camera for monitoring purpose. 
     2. Description of Related Art 
     A typical monitor comprises a monitor body and a support with randomly adjustable angle, enabling it to be erected at any position. The monitor body is provided securely with a camera, which is covered by a protective lens for protection and waterproofing purpose. 
     As the lens of the commonly-used monitor is often embedded into the monitor body, and the protective lens and monitor body are coupled tightly (difficult to be disassembled or separated), the service personnel may find it difficult to repair, maintain and replace it regularly despite of a certain degree of protection and waterproofing function. In such case, this will lead to higher cost in the event of any damage during assembly or disassembly process. 
     To this end, the inventor has provided the present invention of practicability for the benefit of the people after deliberate design based on his years of experience. 
     SUMMARY OF THE INVENTION 
     The main objective of the present invention is to provide a combined structure of waterproof lens and waterproof camera, which enables simple assembly or disassembly and subsequent repair, maintenance or replacement. 
     The present invention comprises: a waterproof lens and a waterproof camera; in particular, the locking portions, such as internal thread and groove, are arranged onto the hollow wall of a socket end of the waterproof lens, while snapping portions, such as external thread and retaining clip, are arranged around an embedding end of the waterproof camera; based on this structural design, the waterproof lens and waterproof camera can be combined easily by the matched locking portions and snapping portions, thus realizing rapid separation for subsequent efficient repair, maintenance and replacement. 
     The features and the advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of a preferred embodiment of the present invention with reference to the accompanying drawings.

     DETAILED DESCRIPTION OF THE INVENTION 
     Referring to  FIG. 1 , the combined structure of the waterproof lens and waterproof camera for monitoring purpose may at least comprise: a waterproof lens  1  and a waterproof camera  2 ; of which: 
     Referring to  FIG. 2 , the waterproof lens  1  can be flexibly assembled onto or removed from the monitor body; it further comprising: a pedestal  10 , glass lens  11 , small lens  12  and shield  13 ; the pedestal  10 , with a multi-layer step, is fitted with a reducing through-hole  101  at both ends, of which a socket end  102  is placed at one end; moreover, the locking portion  103  like an internal thread is arranged on the inner wall; the glass lens  11  is made of toughened glass, and a round hole  111  is centrally sleeved onto the pedestal  10 ; the small lens  12  is laterally embedded onto the boundary of the reducing through-hole  101  within the pedestal  10 ; the shield  13  is covered at one side of the glass lens  11 , permitting to restrict and prevent the glass lens  11  from disengagement or fall from the pedestal  10 . 
     Referring to  FIG. 3 , the waterproof camera  2  is similarly provided with a barrel-like or multi-layer lens mount  20 , and also fitted with a reducing through-hole  201  at both ends; a lens  21  and a locking ring  22  are assembled into the through-hole  201 , of which the lens  21  is positioned by the locking ring  22 ; the lens  21  is connected to a waterproof shield  23  fitted with a lens  24 , and a water stop ring  25  is sleeved onto one end for watertight assembly; moreover, an embedding end  202  at one end of the lens mount  20  can be embedded into the socket end  102  corresponding to the pedestal  10  of the waterproof lens  1 , and a snapping portion  203  is arranged at the periphery; the snapping portion  203  of external thread shape can be mated smoothly with the locking portion  103 , such that the waterproof lens  1  and waterproof camera  2  can be combined together. 
     Based on the above structural design, a combined structure of waterproof lens and waterproof camera featuring ease-of-assembly/disassembly can be formed. 
     To combine the waterproof lens  1  with the waterproof camera  2 , the embedding end  202  of the lens mount  20  of the waterproof camera  2  shall be used in a manner that the snapping portion  203  of external thread shape matches the locking portion  103  of internal thread shape on the inner wall of the socket end  102  onto the pedestal  10  of waterproof lens  1 , thereby combining them by means of screwing; as shown in  FIG. 4 , this method enables to combine easily the waterproof lens  1  and waterproof camera  2 ; for disassembly, the waterproof lens  1  and waterproof camera  2  can be separated in a reverse sequence for subsequent repair, maintenance and replacement of waterproof camera  2 . 
     Referring also to  FIG. 5 , the combined structure of the waterproof lens  1  and waterproof camera  2  is equipped with internal and external threads for simple assembly and disassembly; moreover, the snapping portion  203  and locking portion  103  can be adopted in such a manner that the locking portion  103  of groove is arranged on the inner wall of the socket end  102  of the waterproof lens  1 , and the snapping portion  203  of retaining clip arranged around the embedding end  202  of the lens mount  20  of the waterproof camera  2 ; so the waterproof lens  1  and waterproof camera  2  can be combined or separated quickly through the structural design of the retaining clip and groove. 
     As the waterproof lens and waterproof camera are assembled easily and quickly with a simple structure (e.g. combination of internal and external threads, or groove and retaining clip), the service personnel may find it very easy for assembly or disassembly, allowing for trouble-free maintenance; furthermore, with the simple combined structure of the waterproof lens and waterproof camera, the service personnel may conduct regular repair, maintenance and replacement without removal of the waterproof lens, thus improving greatly the productivity. 
     To sum up, the present invention can realize the expected performance in compliance with the requirements of the patent claims. 
     Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
