Description

Technical Field

[0001] This utility model belongs to the field of infrared ranging equipment technology, specifically a vertical infrared ranging device. Background Technology

[0002] An infrared ranging sensor is a sensing device that uses infrared light as a medium for measurement. It has a wide measurement range and short response time, and is mainly used in modern science and technology, national defense, and industrial and agricultural fields.

[0003] The structure of a vertical infrared ranging device mainly includes the following core components: a modulated light emitting unit, a receiving unit, a phase measuring unit, a counting and display unit, a logic control unit, and a power converter. The infrared ranging device utilizes the non-diffusive characteristics and low refractive index of infrared light to calculate the distance by measuring the time it takes for the infrared light to travel from emission to return. When the infrared light is emitted from the device and returns after hitting a reflective object, the device accurately calculates the distance by measuring the time it takes for the infrared light to travel from emission to return and the propagation speed of the infrared light.

[0004] However, existing ranging devices still have some problems. Infrared rangefinders are widely used in infrastructure surveying. Because infrared rangefinders are small in size, they can be operated by hand. However, during application, holding them by hand will always cause shaking, resulting in errors. Therefore, a vertical infrared ranging device is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and address the problems of existing equipment, this utility model proposes a vertical infrared ranging device.

[0006] The technical solution adopted by this utility model to solve its technical problem is a vertical infrared ranging device, including: a support rod, a connecting block fixedly connected to the bottom of the support rod, a vertical rod fixedly connected to the bottom of the connecting block, two sets of positioning grooves on the vertical rod, a reinforcing rod hinged to the arc-shaped surface of the connecting block, a storage groove on one side of the reinforcing rod, an anti-slip pad fixedly connected to the bottom of the storage groove, a connecting rod hinged to one side of the reinforcing rod, an adjusting ring hinged to one end of the connecting rod, the adjusting ring slidably connected to the vertical rod, a rubber positioning block fixedly connected to the inner wall of the adjusting ring, a spring fixedly connected to the inner wall of the rubber positioning block, one end of the spring fixedly connected to the inner wall of the adjusting ring, the rubber positioning block being movably connected to the positioning groove, the spring pushing the rubber positioning block into the positioning groove, the rubber positioning block increasing the friction with the inner wall of the positioning groove, and the cooperation of the spring's own elasticity, thus fixing the position of the adjusting ring.

[0007] Preferably, the support rod is internally threaded with a screw rod, one end of which is fixedly connected to a mounting plate. A mounting bracket is fixedly connected to the upper surface of the mounting plate. The mounting plate has a first limiting groove and a second limiting groove. By rotating the screw rod, the exposed length of the screw rod is adjusted, thereby adjusting the height of the infrared rangefinder so that the height of the infrared rangefinder is flush with the position to be tested, and then the infrared rangefinder can be started to measure the distance.

[0008] Preferably, a first limiting block is slidably connected inside the first limiting groove, a second limiting block is slidably connected inside the second limiting groove, and a limiting shaft is rotatably connected inside the mounting plate. The first limiting groove and the second limiting groove respectively limit the movement range of the first limiting block and the second limiting block, thereby improving the stability of the device and preventing parts from falling off.

[0009] Preferably, damping pads are fixedly connected to the outer sides of the first limiting block, the limiting shaft, and the second limiting block. The three sets of damping pads are respectively attached to the first limiting groove, the mounting plate, and the second limiting groove. Since there are damping pads on the outer sides of the first limiting block, the limiting shaft, and the second limiting block, the stability of the two sets of fixing frames can be ensured when no external force is applied to the double-sided rack, avoiding movement and thus improving the fixing strength of the infrared rangefinder.

[0010] Preferably, a double-sided rack is fixedly connected to the upper surface of the first limiting block, and gears are hinged to both sides of the double-sided rack. The bottom of the gears is fixedly connected to one end of the limiting shaft. Fixing frames are hinged to both sets of gears. Pulling the double-sided rack drives the gears to rotate, thereby adjusting the distance between the two sets of fixing frames, so as to fix and disassemble the infrared rangefinder.

[0011] Preferably, the bottom of the fixing frame is fixedly connected to the upper surface of the second limiting block. A sliding rod is installed on one side of one set of fixing frames. The sliding rod is slidably connected inside the other set of fixing frames. The sliding rod connects the two sets of fixing frames, thereby cooperating with the second limiting block to improve the stability of the two sets of fixing frames and thus improve the fixing strength of the infrared rangefinder.

[0012] The advantages of this invention are as follows: When the device is used outdoors, the position of the adjusting ring can be adjusted so that the rubber positioning block enters the upper positioning groove, and the position of the adjusting ring is fixed so that the connecting rod is fixed in a horizontal state. This makes the three sets of reinforcing rods form a triangle on the outside of the upright, and the anti-slip pad is in direct contact with the ground, which can increase the friction with the ground. The combination of these two factors can improve the stability of the infrared ranging device when used outdoors, thereby avoiding the fluctuation of the infrared signal caused by wind vibration during outdoor measurement. Furthermore, the stable support can reduce the standard deviation of the ranging, thereby improving the accuracy of the vertical infrared ranging device.

[0013] This invention addresses scenarios where the infrared rangefinder device needs to be moved multiple times. By pulling the double-sided rack, the distance between the two sets of fixing brackets can be adjusted, thereby enabling the infrared rangefinder to be fixed and disassembled. The entire process can be completed with one hand, thus improving the ease of installation and disassembly of the infrared rangefinder when it needs to be moved frequently, and consequently improving the ease of use of the infrared rangefinder device.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1-5As shown, a vertical infrared ranging device includes: a support rod 1, a connecting block 2 fixedly connected to the bottom of the support rod 1, a vertical rod 3 fixedly connected to the bottom of the connecting block 2, two sets of positioning grooves 4 opened on the vertical rod 3, a reinforcing rod 5 hinged to the arc-shaped surface of the connecting block 2, a storage groove 6 opened on one side of the reinforcing rod 5, an anti-slip pad 7 fixedly connected to the bottom of the storage groove 6, a connecting rod 8 hinged to one side of the reinforcing rod 5, an adjusting ring 9 hinged to one end of the connecting rod 8, the adjusting ring 9 slidably connected to the vertical rod 3, a rubber positioning block 10 fixedly connected to the inner wall of the adjusting ring 9, a spring 11 fixedly connected to the inner wall of the rubber positioning block 10, one end of the spring 11 fixedly connected to the inner wall of the adjusting ring 9, and the rubber positioning block 10 movably connected to the positioning groove 4;

[0023] In infrastructure surveying, infrared rangefinders are small and can be operated by hand. However, hand-holding them can cause wobbling and errors. Therefore, when using the rangefinder on a horizontal outdoor surface, stability needs to be ensured. A vertical infrared rangefinder is proposed. In practical use, the device is placed on the outdoor ground, and then the adjusting ring 9 is pushed upwards, causing one end of the connecting rod 8 and the rubber positioning block 10 to move synchronously. When the rubber positioning block 10 is in the upper positioning groove 4, the spring 11 pushes the rubber positioning block 10 into the positioning groove 4. The rubber positioning block 10 increases the friction with the inner wall of the positioning groove 4. Combined with the elasticity of the spring 11, this fixes the position of the adjusting ring 9. The other end of the connecting rod 8 then rotates the reinforcing rod 5 outwards about the hinge point with the connecting block 2. The connecting rod 8 is controlled by the adjusting ring 9 and the rubber positioning block 10. The function of the rubber positioning block 10 is to fix it in a horizontal position, thereby cooperating with the connecting block 2 to fix the position of the reinforcing rod 5. This allows the three sets of reinforcing rods 5 to form a triangular shape on the outside of the upright 3. The anti-slip pad 7 is in direct contact with the ground, which can increase the friction with the ground. The combination of the two can improve the stability of the infrared ranging device when used outdoors, avoid the fluctuation of infrared signal caused by wind vibration during outdoor measurement, and the stable support can reduce the standard deviation of the ranging, thereby improving the accuracy of the vertical infrared ranging device. Pushing the adjusting ring 9 downward reduces the angle between the connecting rod 8 and the storage groove 6. The movement of the adjusting ring 9 moves the rubber positioning block 10 from the upper positioning groove 4 to the lower positioning groove 4, so that the connecting rod 8 enters the interior of the storage groove 6, thereby retracting the three sets of reinforcing rods 5 towards the upright 3, reducing the area occupied by the device and improving the convenience of transporting the device.

[0024] Please see Figure 1-5As shown, the support rod 1 is internally threaded with a screw 12. One end of the screw 12 is fixedly connected to a mounting plate 13. A mounting bracket 14 is fixedly connected to the upper surface of the mounting plate 13. The mounting plate 13 has a first limiting groove 15 and a second limiting groove 18. A first limiting block 16 is slidably connected inside the first limiting groove 15, and a second limiting block 19 is slidably connected inside the second limiting groove 18. A limiting shaft 17 is rotatably connected inside the mounting plate 13. The outer sides of the first limiting block 16, the limiting shaft 17, and the second limiting block 19 are all fixedly connected to... There are damping pads, and three sets of damping pads are respectively attached to the first limiting groove 15, the mounting plate 13 and the second limiting groove 18. The upper surface of the first limiting block 16 is fixedly connected to a double-sided rack 20. Gears 21 are hinged to both sides of the double-sided rack 20. The bottom of the gears 21 is fixedly connected to one end of the limiting shaft 17. Fixing frames 22 are hinged to both sets of gears 21. The bottom of the fixing frames 22 is fixedly connected to the upper surface of the second limiting block 19. A sliding rod 23 is installed on one side of one set of fixing frames 22. The sliding rod 23 is slidably connected to the inside of another set of fixing frames 22.

[0025] When installing the infrared ranging device, place the infrared rangefinder on the mounting plate 13 between the two sets of fixing brackets 22. Pull the double-sided rack 20 and the first limiting block 16 backward, causing the two sets of gears 21 to rotate. Because the gears 21 are meshed with the fixing brackets 22, the distance between the two sets of fixing brackets 22 is reduced when the double-sided rack 20 moves backward and drives the two sets of gears 21 to rotate. This allows the two sets of fixing brackets 22 to be in contact with both sides of the infrared rangefinder, thus enabling the infrared rangefinder to be installed. Because the first limiting block 16, the limiting shaft 17, and the second limiting block 19 all have damping pads on their outer sides, the stability of the two sets of fixing brackets 22 can be ensured when no external force is applied to the double-sided rack 20, preventing movement and thus improving the fixing strength of the infrared rangefinder. The distance between the mounting brackets 22 can be adjusted according to the size of the infrared rangefinder, thus allowing different infrared rangefinders to be fixed in place. This ensures that both the infrared transmitter and receiver of the infrared rangefinder are facing the ground. Rotating the screw 12 adjusts its exposed length, thereby adjusting the height of the infrared rangefinder until it is level with the location to be tested. The infrared rangefinder can then be activated to measure the distance. After measurement, pulling the double-sided rack 20 backward causes the two sets of gears 21 to rotate in opposite directions, increasing the distance between the two mounting brackets 22. This allows the infrared rangefinder to be removed. This improves the ease of installation and removal of the infrared rangefinder when frequent movement is required, thereby enhancing the overall convenience of using the infrared rangefinder.

[0026] Working principle: Place the infrared rangefinder on the mounting plate 13, between the two sets of fixing brackets 22. Pull the double-sided rack 20 and the first limiting block 16 backward, driving the two sets of gears 21 to rotate. This reduces the distance between the two sets of fixing brackets 22, making them contact the sides of the infrared rangefinder, thus installing the infrared rangefinder. Place the device on the outdoor ground, then push the adjusting ring 9 upward, causing one end of the connecting rod 8 and the rubber positioning block 10 to move synchronously. When the rubber positioning block 10 is in the upper positioning groove 4, the spring 11 pushes the rubber positioning block 10 into the positioning groove 4, fixing the position of the adjusting ring 9. The connecting rod 8, under the action of the adjusting ring 9 and the rubber positioning block 10, is fixed in a horizontal state, thus cooperating with the connecting block 2 to reinforce the rod. With position 5 fixed, the three sets of reinforcing rods 5 form a triangle on the outside of the upright 3, and the anti-slip pad 7 is in direct contact with the ground, which increases the friction with the ground. The combination of these two factors improves the stability of the infrared rangefinder when used outdoors, preventing wind vibration from causing fluctuations in the infrared signal during outdoor measurements. This ensures that both the infrared transmitter and receiver of the infrared rangefinder are facing the ground. By rotating the screw 12, the exposed length of the screw 12 is adjusted, thereby adjusting the height of the infrared rangefinder so that its height is level with the position to be tested. The infrared rangefinder can then be started to measure the distance. After the measurement is completed, the double-sided rack 20 is pulled backward, causing the two sets of gears 21 to rotate in opposite directions, which increases the distance between the two sets of fixing brackets 22, allowing the infrared rangefinder to be removed.
