DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0024] In order to make the object, technical solution and advantages of the disclosure clearer, the technical solution of the disclosure will be described in detail below. Obviously, the described embodiments are only a part of, rather than all the embodiments of the disclosure. Based on the embodiments of the disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort shall fall within the protection scope of the disclosure.

[0025] Referring to FIGS. 1 to 6, the disclosure provides a knob type waterproof optical controller with a snap, including a base 1 and a cover 2, the base 1 and the cover 2 are threadedly connected to each other, and between the base 1 and the cover 2, a snap structure 4 for restricting relative rotation therebetween is provided. After the base 1 and the cover 2 are threadedly connected to each other, the snap structure 4 may lock the position between the base 1 and the cover 2 to avoid twisting and loosening.

[0026] The snap structure 4 includes an elastic snap strip 4a, a notch 4b and a snap groove 4c, one end of the elastic snap strip 4a is fixedly connected to the notch 4b provided on an edge of an opening of the cover 2, the other end of the elastic snap strip 4a protrudes from the edge of the opening of the cover 2, and the snap groove 4c is formed on the base 1 corresponding to the position of the notch 4b.

[0027] A lower end of the base 1 is fixedly provided with an outer shoulder 1a along its edge, an outer side of the base 1 is provided with an outer thread 1b, and an inner side of the opening end of the cover 2 is provided with an inner thread 8, and the inner thread 8 and the outer thread 1b are threadedly connected to each other.

[0028] A sealing retaining ring 9 is fixedly disposed on an inner side wall of the cover 2, a sealing gasket 7 is disposed on an outer edge of an upper end of the base 1, and the sealing gasket 7 and the sealing retaining ring 9 are sealingly connected with each other. The sealing gasket 7 is made of waterproof silicone material.

[0029] Three perforations 5 are formed in the middle of the base 1 for installing insertion posts 6 and gaps between the insertion posts 6 and the perforations 5 are filled with waterproof sealing material, which may greatly improve the waterproof performance.

[0030] Several anti-slip grooves 3 evenly distributed are formed on an outer side of the cover 2. The cover 2 when held is prevented from sliding through the anti-slip grooves 3.

[0031] With the above structure, the base 1 and the cover 2 are threadedly connected to each other, the upper end of the base 1 with the outer thread 1b is inserted into the opening end of the cover 2, and the base 1 and the cover 2 threadedly rotate relative to each other. After the base 1 and the cover 2 are threadedly connected to each other, the elastic snap strip 4a snaps into the snap groove 4c formed in the corresponding position of the base 1, as shown in FIG. 5 of the specification, at which time, a movable end of the elastic snap strip 4a cooperates with the snap groove 4c to realize clamping of the base 1 and the cover 2 so that the base 1 and the cover 2 cannot rotate relative to each other, and at which time, the sealing gasket 7 on the outer edge of the upper end of the base 1 abuts the sealing retaining ring 9, and the sealing gasket 7 is in a compressed state to achieve waterproof sealing.

[0032] As shown in FIG. 8 of the specification, an upper part of the figure is the optical controller of the disclosure, and a lower part of the figure is a socket of the disclosure. When the cover 2 is held to threadedly connect the optical controller to the socket, the snap structure 4 may lock the position between the base 1 and the cover 2 to avoid twisting and loosening.

[0033] With the snap structure 4, the base 1 and the cover 2 may be clamped and prevented from being retreated after being threadedly connected to each other, so as to prevent the optical controller structure from loosening during use, and the sealing gasket 7 and the sealing retaining ring 9 cooperate with each other, which may greatly improve the waterproof effect of the optical controller.

[0034] The above are only specific embodiments of the disclosure, but the protection scope of the disclosure is not limited thereto, and any person skilled in the art may easily conceive change or replacement within the technical scope disclosed by the disclosure, which shall be covered within the protection scope of the disclosure. Therefore, the protection scope of the disclosure shall be based on the protection scope of the claims.
