Description

Technical Field

[0001] This utility model relates to the field of ultraviolet radiometer technology, specifically to an ultraviolet radiometer with a fixed-point limiting function. Background Technology

[0002] An ultraviolet (UV) radiometer is an instrument used to measure the intensity of ultraviolet radiation. It is widely used in medical, industrial, scientific research, and environmental monitoring fields. The UV radiometer converts ultraviolet radiation into an electrical signal through a built-in ultraviolet sensor (such as a photodiode or thermopile), and then displays the irradiance value after circuit processing.

[0003] For example, a UV radiometer with Chinese patent publication number CN208171438U relates to an ultraviolet detection instrument, which includes a detector and several control buttons. The detector has a cover on the side where the control buttons are located. The cover includes a first cover body and a second cover body that are interlocked. The detector has a first sliding groove and a second sliding groove spaced apart along its width direction. The detector has a display screen. The detector has an anti-detachment protrusion on the side away from the display screen. The cover has a groove, and the detector has a corresponding protrusion. The detector has anti-slip protrusions on both sides in its width direction. The detector has a probe socket. The detector also has a movable cover for covering the probe socket.

[0004] When existing ultraviolet radiometers are in use, the probe is in an unrestricted state, which means that when detecting some light sources, external components are needed to restrict the probe before detection can be performed. This makes it impossible for existing probes to perform adjustable and positional detection. Therefore, an improved device is needed to address the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an ultraviolet radiometer with a fixed-point limiting function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an ultraviolet radiometer with a fixed-point limiting function, comprising an ultraviolet radiometer, a wire harness fixedly installed at the top of the ultraviolet radiometer, a bearing device fixedly installed at the end of the wire harness away from the ultraviolet radiometer, an adjusting device slidably sleeved at the bottom of the bearing device, and a positioning device rotatably installed at the bottom of the adjusting device. The bearing device includes a probe, a support arm, a connecting plate, and an adjusting frame. The probe is fixedly installed at the top of the side end of the support arm, the connecting plate is fixedly installed at the bottom ends of both sides of the support arm, and the adjusting frame is fixedly installed at the bottom end of the connecting plate.

[0007] Preferably, the adjusting device includes a positioning sleeve, a pin, a magnetic chuck, and a gear. The positioning sleeve is fixedly installed at the top center of the gear, the pin is slidably inserted into the top side of the positioning sleeve, and the magnetic chuck is fixedly installed on the outer ring of the pin away from the positioning sleeve.

[0008] Preferably, the positioning device includes a U-shaped sliding sleeve, a bolt, a support base, a positioning vertical frame, a chassis, and a rack. The positioning vertical frame is fixedly installed at the top center of the support base, the chassis is fixedly installed on both sides of the positioning vertical frame, the bolt is rotatably installed on one end of the positioning vertical frame, the U-shaped sliding sleeve is threaded onto the outer ring of the bolt, and the rack is symmetrically fixedly installed on the end of the U-shaped sliding sleeve away from the bolt.

[0009] Preferably, the gears are rotatably mounted on the top two sides of the positioning frame, and the rack meshes with the gears, while the adjusting frame is slidably inserted into the top of the positioning sleeve.

[0010] Preferably, the surface of the adjustment frame is provided with equally spaced circular holes.

[0011] Preferably, a locking key is fixedly installed at the bottom end of the rack, and a locking groove is provided at the top end of the chassis.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] When in use, this device allows the adjustment frame to slide inside the positioning sleeve, extending the probe's operating range. Simultaneously, inserting a pin into the adjustment frame restricts its movement. Tightening the bolt moves the U-shaped sliding sleeve back to its original position, allowing the rack to move at the bottom of the gear. This enables the positioning sleeve to support the probe's rotation to a specified angle, facilitating probe adjustment to the designated angle for detection. Attached Figure Description

Detailed Implementation

[0019] 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 protection scope of the present utility model.

[0020] Please see Figure 1-4 One embodiment of this utility model is a UV radiometer with a fixed-point limiting function, comprising a UV radiometer 4, a wire harness 5 fixedly installed at the top of the UV radiometer 4, a bearing device 1 fixedly installed at the end of the wire harness 5 away from the UV radiometer 4, an adjusting device 2 slidably sleeved at the bottom of the bearing device 1, and a positioning device 3 rotatably installed at the bottom of the adjusting device 2. The bearing device 1 includes a probe 6, a support arm 7, a connecting plate 8, and an adjusting frame 9. The probe 6 is fixedly installed at the top of the side end of the support arm 7, the connecting plate 8 is fixedly installed at the bottom ends of both sides of the support arm 7, and the adjusting frame 9 is fixedly installed at the bottom end of the connecting plate 8.

[0021] The adjustment device 2 includes a positioning sleeve 10, a pin 11, a magnetic chuck 12, and a gear 13. The positioning sleeve 10 is fixedly installed at the top center of the gear 13. The pin 11 is slidably inserted into the top side of the positioning sleeve 10. The magnetic chuck 12 is fixedly installed on the outer ring of the pin 11 away from the positioning sleeve 10. The top side of the positioning sleeve 10 has a hole that matches the pin 11, so that the pin 11 can easily pass through the positioning sleeve 10 and be inserted into the interior of the adjustment frame 9.

[0022] The positioning device 3 includes a U-shaped sliding sleeve 14, a bolt 15, a support base 16, a positioning vertical frame 17, a chassis 18, and a rack 19. The positioning vertical frame 17 is fixedly installed at the top center of the support base 16, and the chassis 18 is fixedly installed on both sides of the positioning vertical frame 17. The bolt 15 is rotatably installed on one end of the positioning vertical frame 17. The U-shaped sliding sleeve 14 is threaded onto the outer ring of the bolt 15. The rack 19 is symmetrically fixed on the end of the U-shaped sliding sleeve 14 away from the bolt 15. When the bolt 15 is turned in both directions, it can drive the rack 19 to move back to the original position, so that the rotation angle of the gear 13 can be flexibly adjusted.

[0023] Gear 13 is rotatably mounted on both top ends of the positioning vertical frame 17, and rack 19 meshes with gear 13. Adjusting frame 9 is slidably inserted into the top end of positioning sleeve 10, which can support the adjusting frame 9 to slide and adjust in a straight line.

[0024] The surface of the adjustment frame 9 has equally spaced circular holes to facilitate the insertion of the pin 11 into the interior of the adjustment frame 9.

[0025] A locking key is fixedly installed at the bottom of the rack 19, and a locking groove is provided at the top of the chassis 18 to support the rack 19 to move in a straight line.

[0026] Working principle: In use, external screws can be inserted through the support base 16 and installed into the designated area to fix the support base 16. Then, the bolt 15 can be screwed on, and the U-shaped sleeve 14 is threaded onto the outer ring of the bolt 15. When the bolt 15 is screwed on, it can drive the U-shaped sleeve 14 and the rack 19 to move. The rack 19 meshes with the gear 13, so that when the rack 19 moves at the bottom end of the gear 13, it can drive the gear 13 to rotate. Thus, the gear 13 can support the probe 6 to rotate to the designated angle for operation. The rack 19 is displaced by a key at its bottom end within a slot on the top of the chassis 18, allowing it to move linearly. Then, when the probe 6 rotates to a specified angle, the pin 11 can be pulled out from the inside of the adjusting frame 9, releasing the adjusting frame 9. The adjusting frame 9 is then pulled upwards until it moves to a specified height inside the positioning sleeve 10, aligning the circular hole at that height with the pin 11. The pin 11 is then inserted into the circular hole inside both the positioning sleeve 10 and the adjusting frame 9, thus allowing the adjusting frame 9 to move within the positioning sleeve 10. Internally, the device is fixed in place. Simultaneously, by fully inserting the pin 11 into the round hole inside the adjusting frame 9, the magnetic chuck 12 can adhere to the positioning sleeve 10. The positioning sleeve 10 is made of iron, allowing the magnetic chuck 12 to be attracted to its surface, preventing the pin 11 from falling out of the adjusting frame 9. Then, the ultraviolet radiometer 4 is operated. The probe 6 is aligned with an external light source, allowing the light to illuminate the probe 6. The probe 6 converts ultraviolet radiation into an electrical signal, which is then processed by the circuit and displayed on the ultraviolet radiometer 4 as an irradiance value, completing the measurement of ultraviolet radiation intensity. In the operation of the degree detection device, when the bolt 15 is tightened, the rotation angle of the probe 6 can be changed by the movement of the rack 19 at the bottom of the gear 13, making it easier for the probe 6 to align with the light source at different angles. At the same time, the adjusting bracket 9 can slide up and down inside the positioning sleeve 10, thereby extending the working position of the probe 6, making it easier for the probe 6 to accurately align with the light source. Furthermore, by inserting the pin 11 into the adjusting bracket 9, the probe 6 can be restricted, allowing the probe 6 to be supported to detect the light source at a specified angle, thus completing the work.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
