Description

Technical Field

[0001] The utility model belongs to the technical direction of lens production and processing, and specifically relates to a lens rapid locking, positioning and loosening structure. Background Art

[0002] Lens transfer and matching are relatively common structures. For example, patent number: 202223081529.X discloses a lens cover and lens assembly, including a lens body and a lens cover, a lens is provided in the lens cover, a sealing slot is provided on the lens body, a locking assembly is provided between the lens body and the lens cover, and the locking assembly is composed of a slide rod, a locking pin, a spring, and a pull ring. A fixing seat is provided on the outer shell of the lens body, a slot and a sliding cavity are provided in the fixing seat, and a pin is provided on the end of the lens cover facing the fixing seat. The spring is a SPEC plastic spring with high resilience and a long service life.

[0003] The locking assembly of this lens has a complex structure and is inconvenient to use. Utility Model Content

[0004] The purpose of the present invention is to provide a lens quick locking, positioning and loosening structure for existing devices to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a lens quick locking, positioning and loosening structure, including a lens barrel and an adapter barrel, characterized in that: an adapter barrel is provided on the right side of the lens barrel, a movable fixing rod is provided on the outside of the lens barrel, a groove is provided at the position of the fixing rod corresponding to the adapter barrel, a pin is provided at the front of the groove, a spring is provided at the rear end of the groove, the spring and the pin are matched, an oblique groove is provided in the middle of the pin, and the lower end of the fixing rod is matched with the oblique groove.

[0006] Preferably, a hand wheel is provided in the middle section of the lens barrel, and a guide groove is provided on the right side of the adapter barrel.

[0007] Compared with the prior art, the beneficial effect achieved by the present invention is as follows: the present invention utilizes a pin arranged on the adapter tube. When the fixing rod is pressed, the lower end of the fixing rod presses the inclined groove to make the pin retreat, so that the right side of the pin is flush with the guide groove or the pin is hidden within the plane of the guide groove. When the lens is in place, the fixing rod is released, and the pin is engaged in the small hole designed on the matching lens under the rebound action of the spring, thereby realizing the matching of the two lenses. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The following is a non-limiting detailed description of the technical solution of the present invention in conjunction with preferred embodiments and their accompanying drawings. Obviously, the described embodiments are only a portion of the embodiments of the present invention, and not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0012] A lens quick locking, positioning and loosening structure includes a lens barrel 2 and an adapter barrel 5, and is characterized in that: an adapter barrel 5 is provided on the right side of the lens barrel 2, a movable fixing rod 3 is provided on the outside of the lens barrel 2, a groove is provided on the adapter barrel 5 at the position corresponding to the fixing rod 3, a pin 4 is provided at the front of the groove, a spring 7 is provided at the rear end of the groove, the spring 7 cooperates with the pin 4, an oblique groove 8 is provided in the middle of the pin 4, the lower end of the fixing rod 3 cooperates with the oblique groove 8, a handwheel 1 is provided in the middle section of the lens barrel 2, and a guide groove 6 is provided on the right side of the adapter barrel 5. The whole structure is simple and fast, the lens to be docked is rotated along the guide groove, and the fixing rod 3 is released after it is rotated into place. The pin 4 locks the two lenses under the restoring action of the spring 7 to prevent the two lenses from sliding or loosening, which is safe and fast.

[0013] In the description of the present invention, it should be understood that the terms "up", "down", "front", "back", "left", "right", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the present invention.
