Abstract
Description
Technical Field
[0001] This utility model relates to the field of aiming scope technology, specifically to a zoom structure for an infrared thermal imaging aiming lens. Background Technology
[0002] The infrared thermal imaging sight has an infrared aiming lens attached to its body. The infrared aiming lens adjusts the zoom by extending and retracting an adjustment ring. Generally, the adjustment ring is connected to the housing of the infrared aiming lens by a thread. However, during the extension and retraction adjustment, due to the small thread pitch, it is necessary to turn the adjustment ring many times to complete the adjustment, making the whole adjustment process inconvenient. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide an infrared thermal imaging aiming lens zoom structure that addresses the shortcomings of the prior art.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0005] An infrared thermal imaging aiming lens zoom structure includes an aiming scope housing, an objective lens housing connected to one side of the aiming scope housing, an infrared aiming lens disposed inside the objective lens housing, an adjustment knob disposed on the top of the objective lens housing, an adjustment shaft disposed in the middle of the adjustment knob, an adjustment gear connected to the bottom of the adjustment shaft, an adjustment groove machined on the surface of the infrared aiming lens, the adjustment gear being connected in the adjustment groove, teeth machined on one side of the adjustment groove engaging with the adjustment gear, a guide pin connected to the tail of the objective lens housing, a guide groove machined on the outer side of the infrared aiming lens, and the guide pin being engaged in the guide groove.
[0006] Furthermore, a locking screw is connected around the periphery of the objective lens housing, with the locking screw facing the infrared aiming lens.
[0007] Furthermore, the clamping screw is a glass ball screw.
[0008] Furthermore, a mounting hole is machined on the top of the objective lens housing, and a bearing sleeve is installed in the mounting hole. The bearing sleeve is installed on the objective lens housing by screws around its periphery. A bearing is installed inside the bearing sleeve, and a pressure ring is installed at the upper end of the bearing to press the bearing. The adjustment shaft of the adjustment knob is connected to the bearing, and a keyway is machined through the lower end of the adjustment shaft through the bearing. A key block is installed in the keyway to connect with the adjustment gear.
[0009] Furthermore, the adjustment knob is machined with clearance holes for mounting and dismounting screws.
[0010] Compared with the prior art, the infrared thermal imaging aiming lens zoom structure of this utility model has the following beneficial effects:
[0011] 1. Compared to the adjustment ring, the adjustment knob is smaller in size and easier to turn;
[0012] 2. The adjustment knob is connected to the infrared aiming lens by a gear meshing method, which requires fewer turns during adjustment and enables quick adjustment. Attached Figure Description
[0013] Figure 1 This is a schematic diagram of the structure of this utility model;
[0014] Figure 2 yes Figure 1 Enlarged view of point A in the middle;
[0015] The components include: 1. scope housing, 2. objective lens housing, 3. infrared aiming lens, 4. adjustment knob, 5. adjustment shaft, 6. adjustment gear, 7. gear, 8. bearing sleeve, 9. screw, 10. clearance hole, 11. bearing, 12. pressure ring, 13. key block, 14. guide pin, 15. guide groove, and 16. clamping screw. Detailed Implementation
[0016] The technical solutions in the embodiments of this utility model will be clearly and completely described below.
[0017] like Figure 1 and Figure 2 As shown, an infrared thermal imaging aiming lens zoom structure includes an aiming lens housing 1, an objective lens housing 2 connected to one side of the aiming lens housing 1, an infrared aiming lens 3 disposed inside the objective lens housing 2, an adjustment knob 4 disposed on the top of the objective lens housing 2, an adjustment shaft 5 disposed in the middle of the adjustment knob 4, an adjustment gear 6 connected to the bottom of the adjustment shaft 5, an adjustment groove machined on the surface of the infrared aiming lens 3, the adjustment gear 6 connected in the adjustment groove, and a tooth 7 machined on one side of the adjustment groove meshing with the adjustment gear 6. By turning the adjustment knob 4, the adjustment gear 6 drives the infrared aiming lens 3 through the tooth 7. Because the adjustment knob 4 is small in size and the turning method is more convenient, during the adjustment process, the rotation circle of the gear is the adjustment distance of the infrared aiming lens 3. Compared with the adjustment circle method, the number of rotation circles is reduced, and the adjustment is more convenient.
[0018] In this embodiment, a mounting hole is machined on the top of the objective lens housing 2, and a bearing sleeve 8 is installed in the mounting hole. The bearing sleeve 8 is installed on the objective lens housing 2 by screws 9 around its periphery. The adjustment knob 4 is machined with clearance holes 10 for installing and removing the screws 9. A bearing 11 is installed inside the bearing sleeve 8, and a pressure ring 12 is installed at the upper end of the bearing 11 to press the bearing 11. The adjustment shaft 5 of the adjustment knob is connected to the bearing 11. The lower end of the adjustment shaft 5 passes through the bearing 11 and is machined with a keyway. A key block 13 is installed in the keyway and connected to the adjustment gear 6.
[0019] The objective lens housing 2 is symmetrically connected to the tail end with guide pins 14, and the infrared aiming lens 3 has a guide groove 15 machined on its outer side. The guide pins 14 are inserted into the guide groove 15, which makes the adjustment of the infrared aiming lens 3 more stable.
[0020] The objective lens housing 2 is connected to a locking screw 16 around its periphery. The locking screw 16 faces the infrared aiming lens 3. In this embodiment, the locking screw 16 is a glass ball screw. The glass ball screws are symmetrically arranged on both sides of the infrared aiming lens 3. The head of the glass ball screw is provided with a steel ball and a spring is provided inside. The spring presses the steel ball to form a pre-tightening force on the infrared aiming lens 3, which can prevent the infrared aiming lens 3 from loosening.
[0021] This utility model is not limited to the embodiments described. Those skilled in the art can still make some modifications or changes without departing from the spirit and scope of this utility model. Therefore, the scope of protection of this utility model shall be determined by the scope defined in the claims.
