[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] The present invention provides a sealable and easily disassembled lens for an optical instrument, comprising a connecting tube 1:

[0038] The protection mechanism 4 realizes a wrapping shielding protection for the lens when not in use, preventing the lens from being contaminated and damaged, thereby improving the protection effect;

[0039] The mounting mechanism 2 includes a connecting assembly and a locking assembly, wherein the connecting assembly is arranged on the inner side wall of the connecting pipe 1, and the locking assembly is arranged on the bottom of the outer side of the connecting pipe 1;

[0040] The adapter mechanism 3 includes a positioning assembly, a supporting assembly and a sealing assembly. The positioning assembly is arranged at the bottom end of the connecting tube 1, the supporting assembly is arranged at the outside of the positioning assembly, and the sealing assembly is arranged at the top of the supporting assembly.

[0041] The cooperation between the connecting component and the locking component and the positioning component, the supporting component and the sealing component provides the advantages of convenient assembly and disassembly, increased connectivity and improved sealing effect.

[0042] Preferred:

[0043] like Figure 4 As shown, the connection assembly includes an arc-shaped adapting groove 21, which is opened on the inner wall of the connecting tube 1, and a first magnetic block 22 is embedded at the top of the inner cavity of the arc-shaped adapting groove 21 for adapting the inserted lens body 31.

[0044] like Figure 4 As shown, the locking assembly includes a ring plate 23, which is fixedly installed on the outside of the connecting tube 1, a first externally threaded tube 24 is fixedly installed on the bottom of the ring plate 23, an internally threaded tube 25 is threadedly connected to the outside of the first externally threaded tube 24, and a first rubber ring 26 is fixedly installed on the bottom of the first externally threaded tube 24, so as to achieve an inserted and sealed connection with the outer part of the lens body 31 and fasten and fix it by means of threads.

[0045] further:

[0046] like Figure 3 As shown, the positioning assembly includes a lens body 31, which is inserted into the interior of the connecting tube 1, and connecting frames 32 are embedded on both sides of the lens body 31, a second magnetic block 33 is embedded on the top of the connecting frame 32, and a sliding block 34 is fixedly installed at one end of the bottom of the connecting frame 32;

[0047] The sliding block 34 is slidably connected to the inside of the arc-shaped adapting groove 21, and the first magnetic block 22 and the second magnetic block 33 are magnetically attracted.

[0048] The first magnetic block 22 and the second magnetic block 33 use the principle of mutual attraction to achieve adsorption, and based on the above components, connection and positioning operations can be achieved during the installation process.

[0049] like Figure 3 As shown, the support assembly includes a fixing ring 35, which is fixedly mounted on the outside of the lens body 31, a third rubber ring 36 is fixedly mounted on the bottom of the fixing ring 35, and a support plate 37 is fixedly mounted on the outside of the fixing ring 35, which can be used to play a supporting role and facilitate the bearing of the connected components.

[0050] like Figure 3As shown, the sealing assembly includes a second rubber ring 38 and a second externally threaded tube 39, the second rubber ring 38 and the second externally threaded tube 39 are both fixedly mounted on the top of the support plate 37, the second rubber ring 38 is located on the outside of the second externally threaded tube 39, and a groove 310 is formed on the top of the second externally threaded tube 39;

[0051] The first rubber ring 26 is inserted into the groove 310 , and the internal threaded tube 25 is threadedly connected with the second external threaded tube 39 .

[0052] The sealing connection work can be achieved according to the above-mentioned insertion method and the pressing method, and the sealing after the connection can be increased.

[0053] When installing:

[0054] The hand-held lens body 31 drives the connecting frame 32 and the sliding block 34 to be inserted into the arc-shaped adapter groove 21, and then continues to move upward until it cannot move upward, and then rotates. When it cannot rotate, it stops rotating. In this process, the first magnetic block 22 and the second magnetic block 33 are directly magnetically adsorbed, and the adsorption is carried out in a manner of opposite poles attracting each other. At the same time, the first rubber ring 26 is directly inserted into the groove 310, and then the internal threaded tube 25 is rotated. At this time, the internal threaded tube 25 is threaded downward and continues to be threaded downward to be connected with the second external threaded tube 39, and the bottom end of the internal threaded tube 25 is pressed against the top of the second rubber ring 38 to form an installation and sealing work;

[0055] Based on the above, it is the state shown in the figure;

[0056] During disassembly, rotate the internal threaded tube 25 counterclockwise to disengage from the second external threaded tube 39, and then reversely rotate the lens body 31. When it cannot be rotated any further, simply pull it downwards to complete the disassembly. According to the above, the inserted components will now be disengaged until the two are completely separated to complete the disassembly.

[0057] Finally, the protection mechanism 4 includes an elastic component, a bearing component and a shielding component. The elastic component is arranged on the outside of the connecting tube 1, the bearing component is arranged on the outside of the connecting tube 1, and the shielding component is arranged at the bottom end of the connecting tube 1.

[0058] like Figure 6 As shown, the elastic component includes a support tube 41, which is fixedly installed on both sides of the connecting tube 1, a spring 42 is welded at one end of the inner cavity of the support tube 41, a stop plate 43 is welded at the outer end of the spring 42, and a toggle plate 44 is fixedly installed on the top and bottom of the stop plate 43;

[0059] Limiting holes 45 are formed at the top and bottom of the support tube 41 , and the shifting plate 44 is located inside the limiting holes 45 .

[0060] It is conducive to achieving the support and elastic pushing and tightening effect during the protection process and after rotation

[0061] like Figure 6 As shown, the bearing assembly includes a first fixing rod 46, which is fixedly mounted on both sides of the connecting pipe 1, and a mounting plate 47 is fixedly mounted on the outer end of the first fixing rod 46. The support tube 41 and the spring 42 are both located on the outer side of the first fixing rod 46, and the abutment plate 43 is sleeved on the outer side of the first fixing rod 46.

[0062] It can support the components on the outside to ensure the stability of operation.

[0063] like Figure 6 As shown, the shielding assembly includes a vertical plate 411, a sliding hole 48 is opened on the outer side of the vertical plate 411, the vertical plate 411 is sleeved on the outer side of the first fixed rod 46 through the sliding hole 48, a second fixed rod 49 is fixedly installed at the bottom end of the inner side of the vertical plate 411, and a blocking cover 410 is fixedly installed at the inner end of the second fixed rod 49.

[0064] The lens can be shielded and protected so that it will not be contaminated or damaged when not in use.

[0065] The picture shows the protection status. When you need to cancel the protection status, the specific operations are as follows:

[0066] At the same time, the toggle plate 44 is pushed inward to drive the abutment plate 43 to move inward and squeeze the spring 42. Then, the blocking cover 410 is held and drives the vertical plate 411 to move downward. Then, when the blocking cover 410 and the vertical plate 411 cannot move downward, the blocking cover 410 and the vertical plate 411 are rotated to change from the vertical state to the horizontal state and then the blocking cover 410 is pushed to move horizontally again until the blocking cover 410 cannot move. Then, the thrust applied to the toggle plate 44 is released, and the elastic push completes the tightening operation.

[0067] When protection is needed, the above operation can be reversed, that is, first pull it outward, then rotate it, and push it upward again until it covers the outside of the lens body 31 to complete the protection operation.

[0068] 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.
