Description

Technical Field

[0001] The utility model relates to the technical field of infrared sights, in particular to an infrared sight with battery reverse connection prevention. Background Technique

[0002] An infrared sight is an instrument that uses the infrared light reflected by a target to perform optoelectronic conversion and imaging for night aiming. Its working principle is to collect and form an image through the thermal radiation of an object itself, and it can work normally in the dark or during the day. Compared with white light sights and other sights, it has higher combat versatility.

[0003] When an infrared sight is in use, the battery needs to be installed in the mirror body first, and the correct installation of the battery is a necessary condition for the sight to work. If the positive and negative poles of the battery are connected wrongly, it may damage the circuit or internal components of the sight.

[0004] To solve the above problems, a battery reverse connection prevention infrared sight is proposed in this application. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides an infrared sight with battery reverse connection prevention, which includes a lens barrel. A calibration knob, a battery box and a mounting block are fixedly arranged on the lens barrel. A battery slot, a positive electrode slot, a negative electrode slot and a pattern slot are opened on the battery box. A positive electrode connector, a negative electrode connector and a box cover are fixedly arranged on the battery box. A screw is spirally arranged on the box cover. A sliding slot is opened on the mounting block. A lead screw is rotatably arranged on the mounting block. Knobs are fixedly arranged at both ends of the lead screw. A fixing clip is spirally arranged on the lead screw. A slider is fixedly arranged on the fixing clip.

[0006] Preferably, the battery box and the mounting block are fixedly connected to the bottom of the battery box. The positive electrode slot, the negative electrode slot and the pattern slot are opened in the battery slot. The positive electrode connector is fixedly connected in the positive electrode slot. The negative electrode connector is fixedly connected in the negative electrode slot.

[0007] Preferably, the depth of the positive electrode slot is greater than that of the negative electrode slot. The height of the positive electrode connector is less than the depth of the positive electrode slot. The width of the positive electrode slot is greater than the width of the battery positive electrode and less than the width of the battery negative electrode.

[0008] Preferably, the box cover is movably connected in the battery slot. The bottom of the box cover and the bottom of the battery box are on the same horizontal plane. Threaded holes are opened on both the box cover and the battery box. The screw is spirally connected in the threaded hole.

[0009] Preferably, the slider is slidably connected in the sliding slot. The shapes of the slider and the sliding slot are both "T" shaped.

[0010] Preferably, the fixing clip is slidably connected to the middle of the inner side of the mounting block, and the inner side of the knob is rotatably connected to the outer side of the mounting block.

[0011] The above technical solution of the present utility model has the following beneficial technical effects:

[0012] In the present utility model, the positive and negative connectors in the battery box are respectively installed in the positive and negative slots with different depths. Since the height of the positive connector is less than the depth of the positive slot, the width of the positive slot is greater than the width of the battery positive electrode but less than the width of the battery negative electrode, and the positive connector of the battery is in a convex state, so that the positive electrode of the battery can penetrate into the positive slot and contact the positive connector. When the positive and negative electrodes of the battery are reversed, the width of the battery negative electrode is greater than the width of the positive slot, so the battery negative electrode cannot enter the positive slot to contact the positive connector, thus the circuit cannot be closed, and further the aiming scope cannot be used, avoiding damage to the circuit and internal components, and prolonging the service life of the aiming scope; at the same time, a "T" - shaped slider is arranged on the fixing clip and slidably installed in the chute of the mounting block, and a knob and a lead screw are used to control the relative movement of the two fixing clips in the middle of the mounting block, so as to change the distance between the two fixing clips, enabling the aiming scope to be fixed on devices of different sizes.

A positive electrode connector 203, a negative electrode connector 205, and a box cover 4 are fixedly provided on the battery box 2. A screw 401 is spirally provided on the box cover 4. A chute 301 is provided on the mounting block 3. A lead screw 302 is rotatably provided on the mounting block 3. Knobs 303 are fixedly provided at both ends of the lead screw 302. A fixing clip 5 is spirally provided on the lead screw 302. A slider 501 is fixedly provided on the fixing clip 5. The battery box 2 and the mounting block 3 are fixedly connected to the bottom of the battery box 2. The positive electrode slot 202, the negative electrode slot 204, and the pattern slot 206 are provided in the battery slot 201. The positive electrode connector 203 is fixedly connected in the positive electrode slot 202. The negative electrode connector 205 is fixedly connected in the negative electrode slot 204. The depth of the positive electrode slot 202 is greater than the depth of the negative electrode slot 204. The height of the positive electrode connector 203 is less than the depth of the positive electrode slot 202. The width of the positive electrode slot 202 is greater than the width of the battery positive electrode. The width of the positive electrode slot 202 is less than the width of the battery negative electrode. The box cover 4 is movably connected in the battery slot 201. The bottom of the box cover 4 and the bottom of the battery box 2 are on the same horizontal plane. Threaded holes are provided on both the box cover 4 and the battery box 2. The screw 401 is spirally connected in the threaded hole. The slider 501 is slidably connected in the chute 301. The shapes of the slider 501 and the chute 301 are both "T" shaped. The fixing clip 5 is slidably connected to the middle of the inner side of the mounting block 3. The inner side of the knob 303 is rotatably connected to the outer side of the mounting block 3.

[0024] Specifically, two calibration buttons 101 are provided on the lens barrel 1 to adjust the aiming point of the sighting scope, making the position information more accurate. A battery box 2 and a mounting block 3 are fixedly welded to the bottom of the lens barrel 1. A battery slot 201 is opened at the bottom of the battery box 2. Two positive electrode slots 202 and a negative electrode slot 204 are opened in the battery slot 201. A positive electrode connector 203 is arranged in the positive electrode slot 202, and a negative electrode connector 205 is arranged in the negative electrode slot 204, enabling the positive and negative electrodes of the battery to be connected to the positive electrode connector 203 and the negative electrode connector 205 respectively, thus forming a correct circuit. At this time, the sighting scope can be used normally. The depth of the positive electrode slot 202 is greater than the height of the positive electrode connector 203, and the width of the positive electrode slot 202 is greater than the positive electrode of the battery, enabling the positive electrode of the battery to enter the positive electrode slot 202 and contact the positive electrode connector 203. The width of the positive electrode slot 202 is less than the negative electrode of the battery, preventing the negative electrode of the battery from entering the positive electrode slot 202 and contacting the positive electrode connector 203, thereby avoiding damage to the circuit and internal components when the battery is reversely connected. At the same time, a pattern slot 206 is opened at the bottom of the battery slot 201, allowing users to directly judge the installation orientation of the battery through the pattern slot 206, making the installation faster and more convenient. A lid 4 is movably installed in the battery box 2, and threaded holes are opened on both the battery box 2 and the lid 4. A screw 401 is screwed into the threaded hole to fix the lid 4 on the battery box 2, thus covering the battery and providing protection for the battery and the circuit. When the lid 4 is installed on the battery box 2, the bottom of the lid 4 and the bottom of the battery box 2 are on the same horizontal plane, so that when the battery box 2 is installed on the firearm, both the bottom of the battery box 2 and the bottom of the lid 4 will closely fit the firearm. A "T"-shaped sliding groove 301 is opened on the mounting block 3, and two "T"-shaped sliders 501 are slidably connected in the sliding groove 301. Fixed clips 5 are fixedly welded to the bottoms of the two sliders 501, and the fixed clips 5 are screwed onto a lead screw 302. The lead screw 302 is rotatably connected to the mounting block 3. When the mounting block 3 rotates, the fixed clips 5 will slide in the middle of the mounting block 3 due to the action of the sliders 501 and the sliding groove 301, causing the two fixed clips 5 to approach or move away from each other, thereby changing the distance between the fixed clips 5 and enabling the sighting scope to be installed on devices of different sizes. Knobs 303 are fixedly welded to both ends of the lead screw 302, facilitating users to adjust the fixed clips 5, enabling faster installation and disassembly.

[0025] Working principle and usage process of the present utility model: First, use a tool to unscrew the screw 401 from the box cover 4, remove the box cover 4 from the battery box 2, then install the battery into the battery slot 201 in the direction of the pattern slot 206, so that the positive and negative electrodes of the battery are respectively connected to the positive electrode connector 203 and the negative electrode connector 205. Then install the box cover 4 onto the battery box 2 and screw on the screw 401 to complete the correct installation of the battery. Next, rotate the knob 303 to adjust the distance between the two fixing clips 5, so that the fixing clips 5 clamp on the device to be used, and complete the installation of the lens barrel 1. Then use the calibration button 101 on the lens barrel 1 to calibrate the aiming center position of the aiming scope, and then the aiming scope can be used normally.
