Description

Technical Field

[0001] This utility model belongs to the field of aiming scope technology, specifically relating to a novel aiming scope eyepiece diopter adjustment structure. Background Technology

[0002] The eyepiece is used on a scope to adjust the relative movement of the eyepiece group's glass to the refractive index, allowing observers with different eyesight to clearly see the image of the object. Traditional adjustment involves a threaded connection between the eyepiece frame and the eyepiece tube for relative movement. Since the eyepiece tube and frame require surface finishing, this can affect the precision of the threaded connection, leading to instability and frequent eyepiece wobble during adjustment, thus impacting the viewing experience. Utility Model Content

[0003] In view of the above-mentioned problems in the prior art, the purpose of this utility model is to provide a new type of sight eyepiece diopter adjustment structure. The structure design of the handwheel and eccentric wheel drives the positioning pin to move along the curved groove, so that the eyepiece glass can move along the eyepiece tube with the eyepiece frame, thereby realizing the position adjustment of the eyepiece glass. The handwheel is locked by the locking component to prevent the eyepiece from shifting.

[0004] A novel eyepiece diopter adjustment structure for a sight includes an eyepiece tube, a handwheel, an eccentric wheel, and a locking assembly. The locking assembly is used to fix the position of the handwheel. The eyepiece tube is sleeved on the eyepiece frame, and the eyepiece frame and eyepiece tube are connected by a positioning pin. The eyepiece frame is fitted with an eyepiece glass assembly. The handwheel is sleeved on the eyepiece tube, and the eccentric wheel is located inside the eyepiece tube. The handwheel meshes with the eccentric wheel, which has a curved groove. The positioning pin is located inside the curved groove. Rotating the handwheel drives the eccentric wheel to rotate, causing the curved groove to move the positioning pin, thereby moving the eyepiece glass assembly along with the eyepiece frame within the eyepiece tube, adjusting the relative distance between the eyepiece glass assembly and the reticle.

[0005] Preferably, the locking assembly includes a locking ring, a pushing ring, and a limiting ring. The locking ring is fitted onto the eyepiece tube and engages with the handwheel, forming a cavity between the locking ring, the eyepiece tube, and the handwheel. The pushing ring and the limiting ring are both located within the cavity. The pushing ring is connected to the locking ring and reciprocates as the locking ring rotates. The limiting ring is connected to the handwheel, and when the pushing ring abuts against the limiting ring, the position of the handwheel is locked.

[0006] Preferably, the end faces of the pushing ring and the limiting ring opposite each other are respectively provided with mutually cooperating protrusions and grooves.

[0007] Preferably, the locking assembly further includes a locking screw, which is installed on the push ring. The eyepiece tube is provided with a limiting groove at the position corresponding to the locking screw, and the reciprocating movement of the push ring is limited by the cooperation of the locking screw and the limiting groove.

[0008] Preferably, the handwheel includes a manual adjustment end located outside the eyepiece tube and a connecting end located inside the eyepiece tube, wherein the connecting end of the handwheel engages with an eccentric wheel.

[0009] Preferably, the eccentric wheel is installed inside the eyepiece tube via a pressure ring.

[0010] Preferably, a locking screw is provided on the handwheel, and a washer is provided at the contact position of the locking screw, the handwheel, and the eccentric wheel.

[0011] The beneficial effects of this utility model are: the new sight eyepiece diopter adjustment structure, through the meshing action of the handwheel and the eccentric wheel, causes the positioning pin to move along its curved trajectory via the curved groove on the eccentric wheel, so that the eyepiece glass can move along the eyepiece tube with the eyepiece frame, thereby adjusting the position of the eyepiece glass and thus adjusting the relative distance between the eyepiece glass and the reticle, thereby achieving eyepiece diopter adjustment.

[0012] The handwheel is locked by setting a locking component. A push ring is set in the cavity formed between the handwheel, the locking ring, and the eyepiece tube. The locking ring drives the push ring to move, so that the handwheel is locked when the push ring comes into contact with the limit ring. Attached Figure Description

[0021] Example 1

[0022] like Figures 1 to 6 As shown, a novel eyepiece diopter adjustment structure for a sight includes an eyepiece frame 1, an eyepiece tube 2, an eyepiece group glass 3, a positioning pin 4, a locking ring 5, a pushing ring 6, a fastening screw 7, a limiting ring 8, an eccentric wheel 9, a washer 10, a locking screw 11, a pressure ring 12, and a handwheel 13.

[0023] like Figures 1 to 3 As shown, the eyepiece glass 3 is assembled inside the eyepiece frame 1. The eyepiece frame 1 is sleeved with the eyepiece tube 2. The eyepiece glass 3 is driven by the handwheel 13 to adjust the relative distance between the eyepiece glass 3 and the reticle, thereby realizing the position adjustment of the eyepiece glass 3.

[0024] Specifically, such as Figures 3 to 6 As shown, the eyepiece frame 1 and the eyepiece tube 2 are connected by a positioning pin 4. An eccentric wheel 9 is arranged inside the eyepiece tube 2, and the position of the eccentric wheel 9 inside the eyepiece tube 2 is limited by a pressure ring 12.

[0025] A handwheel 13 is fitted onto the eyepiece tube 2. The handwheel 13 includes a manual adjustment end located outside the eyepiece tube 2 and a connecting end located inside the eyepiece tube 2. The connecting end of the handwheel 13 engages with an eccentric wheel 9. A curved groove 14 is provided on the eccentric wheel 9. The positioning pin 4 is located in the curved groove 14. The shape of the curved groove 14 limits the movement trajectory of the positioning pin 4.

[0026] Rotating the handwheel 13 causes the eccentric wheel 9 to rotate, which in turn causes the curved groove 14 on the eccentric wheel 9 to drive the positioning pin 4 to move, thereby moving the eyepiece frame 1 along the eyepiece tube 2, thus adjusting the relative distance between the eyepiece assembly glass 2 and the reticle.

[0027] In addition, a locking screw 11 is provided on the handwheel 13 to prevent the handwheel 13 from dislodging, and a washer 10 is provided at the contact position of the locking screw 11, the handwheel 13, and the eccentric wheel 9.

[0028] In order to lock the handwheel 13, this embodiment also provides a locking assembly, which includes a locking ring 5, a pushing ring 6, a fastening screw 7, and a limiting ring 8.

[0029] like Figure 4As shown, the locking ring 5 is fitted onto the eyepiece tube 2 and engages with the handwheel 13, creating a cavity between the locking ring 5, the eyepiece tube 2, and the handwheel 13. The pushing ring 6, the fastening screw 7, and the limiting ring 8 are all located within the cavity. The pushing ring 6 is connected to the locking ring 5 and reciprocates with the rotation of the locking ring 5. The limiting ring 8 is connected to the handwheel 13, and the opposing end faces of the pushing ring 6 and the limiting ring 8 are respectively provided with mutually cooperating protrusions and grooves. In this embodiment, the limiting ring 8 is made of rubber. The elasticity of the rubber material creates frictional resistance against the pushing ring 6, locking the position of the handwheel 13 and preventing the eyepiece from moving due to the recoil of the gun after the diopter adjustment.

[0030] In addition, a fastening screw 7 is provided on the push ring 6, and a limit groove is provided at the corresponding position of the eyepiece tube 2. The position of the push ring 6 reciprocating is limited by the fastening screw 7 and the limit groove.

[0031] Working principle: In use, the eyepiece diopter adjustment structure of this new type of sight unlocks the handwheel 13 by rotating the locking ring 5. Then, through the meshing of the handwheel 13 and the eccentric wheel 9, rotating the handwheel 13 drives the eccentric wheel 9 to rotate, causing the curved groove 14 on the eccentric wheel 9 to drive the positioning pin 4 to move, thereby moving the eyepiece glass group 3 in the eyepiece frame 1 relative to the dividing plate. After the position of the eyepiece glass group 3 is determined, rotating the locking ring 5 drives the push ring 6 to move towards the handwheel 13. When the push ring 6 abuts against the limiting ring 8, the elasticity of the limiting ring 8 creates frictional resistance on the push ring 6, thereby locking the handwheel 13.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
