Description

Technical Field

[0001] The utility model relates to the technical field of automatic focusing, in particular to an observation instrument with automatic focusing and ranging. Background Art

[0002] Focusing an observation instrument involves adjusting the instrument's optical system to ensure that light from distant celestial objects forms a clear image on the focal plane. Proper focus is crucial for successful observations. It directly affects the instrument's resolution and image quality. In astrophotography, precise focus can determine the detail and clarity of captured celestial objects.

[0003] According to Chinese patent publication number CN217332994U, a telescope includes two monocular housings, two objective lens assemblies, two transmission members, and a focusing mechanism. The two objective lens assemblies are slidably connected to the two monocular housings, and one end of each transmission member is connected to the corresponding objective lens assembly. The focusing mechanism is movably connected to the monocular housings and is in transmission connection with the two transmission members to drive the two objective lens assemblies to synchronously extend and retract along the monocular housings. The telescope also includes two eyepiece assemblies, each connected to the two monocular housings.

[0004] In the above solution, focusing is performed by manually rotating the rotating part, which still has the following disadvantages: during manual focusing, the operator may adjust the focus back and forth due to unfamiliarity with the operation, which prolongs the focusing time and reduces the focusing efficiency. Utility Model Content

[0005] The purpose of the utility model is to provide an observation instrument with ranging and automatic focusing, so as to solve the problem that the focusing time is prolonged and the focusing efficiency is reduced due to the possibility of adjusting back and forth near the focus point due to unfamiliarity with the operation.

[0006] In order to achieve the above-mentioned utility model object, the utility model adopts the following technical scheme: an observation instrument with automatic focusing of ranging, comprising an objective tube, wherein the objective tube is arranged inside the observation instrument body, a movable tube is slidably provided inside the objective tube, a positioning groove is provided on the surface of the objective tube, a mounting folding plate is provided inside the observation instrument body, a motor is fixed on one side of the mounting folding plate, the output shaft of the motor is rotatably inserted with the mounting folding plate, a screw is fixed on one end of the motor output shaft, a movable folding plate is slidably provided inside the mounting folding plate, a threaded groove is provided on one side of the top folding plate of the movable folding plate, the screw is threadedly connected to the threaded groove, a movable folding rod is provided on one side of the movable folding plate, a movable plate is fixed on the other end of the movable folding rod, a limit strip is fixed on the bottom surface of the movable plate, and several limit rings are fixed on the surface of the movable tube, a laser ranging unit is provided on the objective tube, and a controller is provided on the objective tube, the controller is electrically connected to the motor, and the controller is electrically connected to the laser ranging unit.

[0007] Preferably, a sliding rod is fixed inside the mounting folding plate, a sliding hole is opened on one side of the movable folding rod, and the sliding hole and the sliding rod are slidably inserted.

[0008] Preferably, a limiting groove is provided on the surface of the movable tube, a limiting opening is provided on the limiting ring, a fixing opening is provided on the surface of the objective tube, a fixed folding plate is detachably provided on the surface of the objective tube, a limiting plug-in plate is fixed to the bottom surface of the fixed folding plate, and the bottom end of the limiting plug-in plate passes through the fixing opening and is inserted into the sliding side of the limiting groove.

[0009] Preferably, a fixing hole is provided on the top surface of the fixing folding plate, a fixing bolt is rotatably inserted into the fixing hole, and the bottom end of the fixing bolt passes through the fixing hole and is threadedly connected to the objective lens tube.

[0010] Preferably, buffer rings are fixedly sleeved on the surfaces of both ends of the sliding rod.

[0011] Preferably, a fixing plate is fixed on the surface of the observation instrument body, and a hanging opening is opened on one side of the fixing plate.

[0012] Preferably, there are two objective lens tubes, one of which is connected to a first bracket, and the other is connected to a second bracket, a third bracket is connected between the first bracket and the second bracket, and a transmission block is connected to the bottom end of the first bracket, and the bottom end of the transmission block is clamped inside the movable folding plate.

[0013] Compared with the prior art, the ranging and auto-focusing observation instrument using the above technical solution has the following beneficial effects:

[0014] 1. In the process of adjusting the focal length, the laser distance measuring unit on the observation instrument will be used to measure the laser distance of the observation target first, and then the monitored distance value will be sent to the controller. The controller will control the opening and closing of the motor according to the distance information. The motor will be started, and the output shaft of the motor will drive the screw to rotate. During the rotation of the screw, the screw will use the threaded connection with the thread groove to drive the movable folding plate to move horizontally inside the installation folding plate, and drive the movable folding rod to move synchronously during the horizontal movement. At this time, since the limit bar at the other end of the movable folding rod will be between the two limit rings, it can drive the movable tube to move inside the objective tube, and thus push the objective lens to produce displacement, thereby realizing automatic focusing, reducing the focusing time and increasing the focusing efficiency;

[0015] Second, when the fixed folding plate is fixed to the surface of the objective tube, the limiting insert plate is driven to pass through the fixing opening and enter the interior of the limiting groove. At this time, the fixed folding plate uses the fixing bolt to increase the firmness of the fixed folding plate on the surface of the objective tube. When the movable tube slides inside the objective tube, the sliding insertion of the limiting insert plate and the limiting groove can limit the sliding distance of the movable tube, thereby preventing the movable tube from slipping out of the objective tube.

[0016] 3. When the movable flap slides on the sliding rod, one side of the movable flap will eventually hit the surface of the buffer ring, thereby buffering the impact force received by the movable flap during movement, thereby increasing the safety of the installation flap and the movable flap during movement, avoiding damage to the movable flap and the installation flap due to frequent collisions, and extending the service life of the installation flap and the movable flap.

[0024] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0025] Example 1:

[0026] like Figures 1-6 As shown, an observation instrument with automatic focusing for ranging includes an objective tube 2, which is arranged inside an observation instrument body 1, a movable tube 3 is slidably arranged inside the objective tube 2, a positioning groove 4 is provided on the surface of the objective tube 2, a mounting folding plate 5 is provided inside the observation instrument body 1, a motor 6 is fixed on one side of the mounting folding plate 5, the output shaft of the motor 6 is rotatably inserted with the mounting folding plate 5, a screw 7 is fixed on one end of the output shaft of the motor 6, a movable folding plate 8 is slidably arranged inside the mounting folding plate 5, a threaded groove 9 is provided on one side of the top folding plate of the movable folding plate 8, and the screw 7 is connected to the threaded The groove 9 is threadedly connected, a movable folding rod 10 is provided on one side of the movable folding plate 8, a movable plate 11 is fixed to the other end of the movable folding rod 10, a limit strip 12 is fixed to the bottom surface of the movable plate 11, and a plurality of limit rings 13 are fixed to the surface of the movable tube 3. A laser ranging unit is provided on the objective tube 2, and a controller is provided on the objective tube 2. The controller is electrically connected to the motor 6, and the controller is electrically connected to the laser ranging unit. A sliding rod 21 is fixed to the inside of the mounting folding plate 5, and a sliding hole 23 is opened on one side of the movable folding rod 10, and the sliding hole 23 and the sliding rod 21 are slidably inserted.

[0027] During use, when adjusting the focal length, the laser distance measuring unit on the observation instrument is first used to measure the distance of the observation target, and then the monitored distance value is sent to the controller (the controller model is JACE200E). The controller controls the opening and closing of the motor 6 according to the distance information. The motor 6 is started, and the output shaft of the motor 6 rotates to drive the screw 7 to rotate. During the rotation process, the screw 7 uses the threaded connection with the thread groove 9 to drive the movable folding plate 8 to move laterally inside the mounting folding plate 5, and drives the movable folding rod 10 to move synchronously during the lateral movement. At this time, since the limit bar 12 at the other end of the movable folding rod 10 is located between the two limit rings 13, it can drive the movable tube 3 to move inside the objective tube 2. It should be noted that this focusing method can cover all observation instruments or equipment, such as telescopes, thermal imagers, night vision devices, sights, etc., which can drive the objective lens to produce displacement, thereby achieving automatic focusing, reducing the focusing time and increasing the focusing efficiency.

[0028] like Figure 2 and Figure 4 As shown, a limit groove 14 is provided on the surface of the movable tube 3, a limit opening 15 is provided on the limit ring 13, a fixing opening 16 is provided on the surface of the objective tube 2, and a fixed folding plate 17 is detachably provided on the surface of the objective tube 2. A limit plug-in plate 18 is fixed to the bottom surface of the fixed folding plate 17, and the bottom end of the limit plug-in plate 18 passes through the fixing opening 16 and is inserted into the slidable side of the limit groove 14. A fixing hole 19 is provided on the top surface of the fixed folding plate 17, and a fixing bolt 20 is rotatably inserted into the inside of the fixing hole 19. The bottom end of the fixing bolt 20 passes through the fixing hole 19 and is threadedly connected to the objective tube 2.

[0029] During use, when the fixed folding plate 17 is fixed to the surface of the objective tube 2, the limiting plug 18 will be driven to pass through the fixing opening 16 and enter the interior of the limiting groove 14. At this time, the fixed folding plate 17 uses the fixing bolt 20 to increase the firmness of the fixed folding plate 17 on the surface of the objective tube 2. When the movable tube 3 slides inside the objective tube 2, the sliding insertion of the limiting plug 18 and the limiting groove 14 can limit the sliding distance of the movable tube 3, thereby preventing the movable tube 3 from slipping out of the objective tube 2.

[0030] like Figure 1 and Figure 3 As shown, buffer rings 22 are fixedly sleeved on the surfaces of both ends of the sliding rod 21 , and a fixing plate 24 is fixed on the surface of the observation instrument body 1 . A hanging opening 25 is opened on one side of the fixing plate 24 .

[0031] During use, when the movable flap 8 slides on the sliding rod 21, one side of the movable flap 8 will eventually hit the surface of the buffer ring 22, thereby buffering the impact force exerted on the movable flap 8 during movement, thereby increasing the safety of the mounting flap 5 and the movable flap 8 during movement, avoiding damage to the movable flap 8 and the mounting flap 5 due to frequent collisions, and extending the service life of the mounting flap 5 and the movable flap 8.

[0032] Example 2:

[0033] like Figure 1 and 5 As shown, there are two objective lens tubes 2, one of which is connected to a first bracket 26, and the other is connected to a second bracket 27. A third bracket 28 is connected between the first bracket 26 and the second bracket 27. A transmission block 29 is connected to the bottom end of the first bracket 26, and the bottom end of the transmission block 29 is clamped inside the movable folding plate 8.

[0034] In use, this device is suitable for driving the two objective lens tubes 2 to focus, and its working principle is the same as that in the first embodiment, specifically as follows:

[0035] By starting the motor 6, the output shaft of the motor 6 drives the screw 7 to rotate. At this time, the screw 7 will be connected to the threaded groove 9 during the rotation process, thereby driving the movable folding plate 8 to move horizontally inside the mounting folding plate 5, and driving the transmission block 29 to move synchronously during the horizontal movement. At this time, the transmission block 29 drives the first bracket 26, the second bracket 27 and the third bracket 28 to move, and then drives the two objective lens tubes 2 to focus at the same time through a single motor 6, thereby reducing the complexity of the operation and improving the efficiency of the focusing work.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
