Description

Technical Field

[0001] The utility model relates to the technical field of sight combination, in particular to an interface structure of a combined optical sight. Background Art

[0002] The sight consists of a center tube, an eyepiece and an objective lens, and the eyepiece and the objective lens are installed at both ends of the center tube through an interface structure; the interface structure of a traditional combined sight consists of external threads on the surfaces of the eyepiece and the objective lens and an internal thread groove of the center tube, and the eyepiece and the objective lens are installed by relative rotation with the center tube.

[0003] The existing installation method has certain disadvantages, especially the threaded connection, whose threaded interface is prone to slipping, resulting in installation mismatch. Secondly, the existing installation structure does not have an adjustment structure, so there is an urgent need for an interface structure of a combined optical sight to solve the above problems. Utility Model Content

[0004] In order to solve the above problems, the utility model provides an interface structure of a combined optical sight, and the utility model is implemented through the following technical solutions.

[0005] The interface structure of a combined optical sight comprises a sight middle tube, a lens assembly, a docking assembly and a rotating adjustment knob, wherein two symmetrical slots are provided inside the sight middle tube, a slide bar is fixedly connected inside the slot, one end of the docking assembly movably embedded inside the sight middle tube is symmetrically fixedly connected with two movable blocks, an annular support plate is fixedly connected inside the docking assembly, a second spring is fixedly connected to the top of the annular support plate, one end of the second spring is fixedly connected with an extrusion seat, two right-angle hook-type slots symmetrically provided inside the docking assembly are slidably matched with the extrusion seat, one end of the lens assembly movably embedded inside the docking assembly is symmetrically fixedly connected with two limit blocks, and the limit blocks are limitedly slid in the right-angle hook-type slots.

[0006] Furthermore, the movable block is slidably connected to one end of the sliding rod, and the other end of the sliding rod is fixedly connected to a first spring.

[0007] Furthermore, the rotation adjustment knob is movably connected to one end of the middle tube of the sight, and the middle tube of the sight is threadedly matched with the rotation adjustment knob, and the rotation adjustment knob is supported at the bottom of the docking assembly.

[0008] Furthermore, the lens assembly is pressed onto the top of the extrusion seat.

[0009] Furthermore, the center tube of the sight, the lens assembly, the docking assembly and the rotating adjustment knob are all located on the same axis.

[0010] Furthermore, an optical lens is arranged inside the lens assembly.

[0011] The beneficial effect of the utility model is that, during the operation of the device, one end of the lens assembly is first inserted into the docking assembly. During the insertion, the lens assembly slides in the right-angle hook-type groove through the limiting block, and at the same time, the lens assembly squeezes the extrusion seat, and the extrusion seat can compress the second spring. When the limiting block slides linearly to the bottom, the limiting block on the lens assembly can be clamped into the right-angle hook-type groove by rotating the lens assembly. At this time, the second spring compression generates a reaction force that can squeeze the lens assembly to be clamped on the docking assembly through the limiting block. Conversely, during disassembly, the lens assembly can be rotated in the opposite direction, so that the lens assembly can be pulled out from the inside of the docking assembly, thereby facilitating the disassembly and assembly between the lens assembly and the docking assembly. At the same time, the docking assembly can be pushed to move by rotating the rotary adjustment knob, so as to adjust the distance between the middle tube of the sight and the docking assembly. The structure is reasonable, easy to assemble, and convenient to adjust. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] By adopting the above technical scheme, when using the device, first use one end of the lens assembly 2 to insert into the docking assembly 3. During insertion, the lens assembly 2 slides in the right-angle hook-type groove 33 through the limiting block 21, and at the same time, the lens assembly 2 squeezes the extrusion seat 322, and the extrusion seat 322 can compress the second spring 321. When the limiting block 21 slides linearly to the bottom, the limiting block 21 on the lens assembly 2 can be clamped into the right-angle hook-type groove 33 by rotating the lens assembly 2. At this time, the second spring 321 is compressed to generate a reaction force that can squeeze the lens assembly 2 to be clamped on the docking assembly 3 through the limiting block 21.

[0028] By adopting the above technical solution, the movable docking assembly 3 can slide within the upper limit of the slide rod 12 through the movable block 31. At the same time, the movable block 31 can squeeze the first spring 121 connected to the slide rod 12. The compressed first spring 121 can be reset for easy adjustment.

[0029] Specifically, the rotary adjustment knob 4 is movably connected to one end of the sight middle tube 1 , and the sight middle tube 1 is threadedly matched with the rotary adjustment knob 4 , and the rotary adjustment knob 4 is supported at the bottom of the docking assembly 3 .

[0030] By adopting the above technical solution, rotating the rotary adjustment knob 4 can push the docking assembly 3 to move on the middle tube 1 of the sight, thereby adjusting the distance between the lens assembly 2 connected to the docking assembly 3 and the middle tube 1 of the sight.

[0031] Specifically, the lens assembly 2 is pressed onto the top of the pressing seat 322 .

[0032] By adopting the above technical solution, the lens assembly 2 can be easily pressed and assembled on the docking assembly 3.
