Description

Technical Field

[0001] The utility model relates to the field of thermal fuse detection equipment, and specifically relates to a RY type thermal fuse operating temperature detection device. Background Art

[0002] The RY type thermal fuse is a thermal protection component, usually used in circuits. When the current exceeds the set value, the thermal fuse will be heated to the fusing temperature, causing it to disconnect the circuit, thereby protecting the circuit and equipment from damage caused by overload or short circuit.

[0003] The existing detection of the RY type thermal fuse usually uses a multimeter. An operator holds the red and blue pens of the multimeter with both hands and contacts both sides of the thermal fuse respectively, and judges whether the thermal fuse can work normally by observing the multimeter value.

[0004] The existing detection method of the RY type thermal fuse by manual detection not only has low work efficiency, but also the thermal fuse usually has a small size, resulting in inconvenient manual detection with a multimeter. Therefore, in view of the above problems, a RY type thermal fuse operating temperature detection device is proposed. Content of the Utility Model

[0005] In order to make up for the deficiencies of the existing technology and address the problems of the existing equipment, the utility model proposes a RY type thermal fuse operating temperature detection device.

[0007] Preferably, first springs are sleeved on both of the telescopic rods. When both sides of the thermal fuse squeeze the test arc blocks, the telescopic rods are driven to contract, and under the action of the first springs, the test arc blocks can be firmly contacted with both sides of the thermal fuse, improving the stability and test accuracy, and avoiding the influence on the detection accuracy due to unstable contact.

[0008] Preferably, the two ladder platforms are respectively oppositely arranged at the lower end of the rear side and the upper end of the front side of the slider. When the upper ladder platform on the front end of the slider contacts the tooth of the straight bevel gear, the straight bevel gear rotates by the contact between the inclined surface of the ladder platform and the front end of the tooth, and at the same time, the inclined surface of the lower ladder platform on the rear end of the slider is in contact with the bottom of the rear end of the tooth, at this time, the inclined surface of the upper ladder platform on the front end of the slider contacts another tooth at the upper end of the tooth, realizing the intermittent rotation of the straight bevel gear.

[0009] Preferably, the first connecting column is arranged on the side of the rotating wheel away from the axis, so that the first connecting column can rotate eccentrically, and then the connecting rod can move horizontally.

[0010] Preferably, the two testing arc blocks are located at the upper ends of both sides of the thermal fuse. The lower end of the testing arc block is designed in an arc shape and is in the shape of a downward parabola. When the two sides of the thermal fuse rotate together with the connecting plate, the two sides of the thermal fuse squeeze the telescopic rod along the downward-sliding track. Under the action of the first spring, the testing arc block is in firm contact with the thermal fuse, increasing the accuracy of the test.

[0011] Preferably, one side of the limiting post is designed in a semi-circular shape. The semi-circular design is conducive to the circular thermal fuse sliding in and out between the connecting plates, facilitating the taking and installation of the thermal fuse.

[0012] The beneficial effects of the present utility model are as follows: The motor drives the rotating wheel to rotate, causing the connecting rod and the slider to move horizontally. When the upper side of the front end of the slider contacts the teeth of the straight gear, the straight gear rotates through the contact between the inclined surface of the step and the front end of the teeth.

At this time, the inclined surface of the upper side of the front end of the slider contacts another tooth at the upper end of the teeth, realizing the intermittent rotation of the straight gear, enabling the two sides of the thermal fuse to be in firm contact with the testing arc block for detection. The thermal fuse can be quickly installed and removed through the limiting post, improving the working efficiency of the thermal fuse detection and reducing the detection difficulty.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-5 As shown, a RY-type thermal fuse operating temperature detection device includes: a base 1, two support rods 2 are fixed at the rear end of the top of the base 1, a rotating shaft 3 penetrates between the tops of the two support rods 2, two support rods 2 are fixed with a support plate 4 at the top, a display 5 is fixed in the middle of the front end face of the support plate 4, telescopic rods 20 are fixed on both sides of the lower end face of the support plate 4, test arc blocks 22 are fixed at the bottoms of the two telescopic rods 20, two ring plates 15 are sleeved on the rotating shaft 3, connecting plates 16 are evenly fixed around the center on the outer shaft bodies of the two ring plates 15, a thermal fuse 14 is movably embedded between the connecting plates 16 on the outer shaft bodies of the two ring plates 15, hole grooves 23 are opened at the front and rear ends of the connecting plate 16, second springs 24 are fixed in the hole grooves 23, limit columns 19 are fixed on one side of the second springs 24, a straight bevel gear 12 is fixedly sleeved on one side of the rotating shaft 3, a support platform 6 is fixed at the front end of one side of the base 1, a motor 8 is fixed on the top of the support platform 6, a runner 9 is fixed at the output end of the motor 8, a first connecting column 10 is fixed on one side of the runner 9, a connecting rod 11 is sleeved on the first connecting column 10, a second connecting column 13 is embedded on one side of the connecting rod 11, a slide block 17 is fixed on one side of the second connecting column 13, a T-shaped sliding table 7 is fixed at a position of the base 1 close to the support platform 6, the slide block 17 is slidably arranged in the upper chute of the T-shaped sliding table 7, and two step platforms 18 are fixed on one side of the slide block 17.

[0023] When testing the thermal fuse 14, place the thermal fuse 14 between two connecting plates 16 on the ring plate 15. Press the thermal fuse 14. When the thermal fuse 14 moves closer to the axis of the rotating shaft 3, it squeezes the limit post 19 to slide into the hole groove 23. When the thermal fuse 14 is in the final position, the limit post 19 pops out under the action of the second spring 24 to fix the thermal fuse 14. Start the motor 8 to drive the runner 9 to rotate, and at the same time make the first connecting post 10 rotate eccentrically around the runner 9. Due to the restriction of the inner chute at the upper end of the T-shaped slide 7, when the first connecting post 10 rotates, it pushes the connecting rod 11, causing the slider 17 to move back and forth in the inner chute at the upper end of the T-shaped slide 7. When the upper side step 18 at the front end of the slider 17 contacts the teeth of the straight bevel gear 12, the straight bevel gear 12 rotates through the contact between the inclined surface of the step 18 and the front end of the teeth. At the same time, the inclined surface of the lower side step 18 at the rear end of the slider 17 is in contact with the bottom of the rear end of the teeth. At this time, the inclined surface of the upper side step 18 at the front end of the slider 17 contacts another tooth at the upper end of the teeth, realizing the intermittent rotation of the straight bevel gear 12, driving the ring plate 15 and the connecting plate 16 to rotate intermittently, so that both sides of the thermal fuse 14 can have time to contact the test arc block 22 and display the test results on the display 5. The bottom of the test arc block 22 is in the shape of a lower parabola. When both sides of the thermal fuse 14 move along the arc track of the test arc block 22, they squeeze the telescopic rod 20. Under the action of the first spring 21, the test arc block 22 can stably contact both sides of the thermal fuse 14. The motor 8 continues to rotate. Hold the middle part of the thermal fuse 14 and pull it outwards, squeezing the limit post 19 to slide in the hole groove 23 again. At the same time, place a new thermal fuse 14 at the vacant place for testing, improving the working efficiency of the thermal fuse detection.

[0024] A first spring 21 is sleeved on each of the two telescopic rods 20. When both sides of the thermal fuse 14 squeeze the test arc block 22, it drives the telescopic rod 20 to contract. Under the action of the first spring 21, the test arc block 22 can stably contact both sides of the thermal fuse 14, improving the stability and test accuracy, and avoiding the influence on the detection accuracy due to unstable contact. The two steps 18 are respectively arranged oppositely at the lower end of the rear side and the upper end of the front side of the slider 17. When the upper side step 18 at the front end of the slider 17 contacts the teeth of the straight bevel gear 12, the straight bevel gear 12 rotates through the contact between the inclined surface of the step 18 and the front end of the teeth. At the same time, the inclined surface of the lower side step 18 at the rear end of the slider 17 is in contact with the bottom of the rear end of the teeth. At this time, the inclined surface of the upper side step 18 at the front end of the slider 17 contacts another tooth at the upper end of the teeth, realizing the intermittent rotation of the straight bevel gear 12.

[0025] The first connecting column 10 is arranged on the side of the runner 9 away from the axis, enabling the first connecting column 10 to rotate eccentrically, and thus enabling the connecting rod 11 to move horizontally. The two test arc blocks 22 are located at the upper ends on both sides of the thermal fuse 14. The lower end of the test arc block 22 is designed in an arc shape, and the lower end of the test arc block 22 is in the shape of a downward parabola. When the two sides of the thermal fuse 14 rotate together with the connecting plate 16, the two sides of the thermal fuse 14 squeeze the telescopic rod 20 along the downward-sliding track. Under the action of the first spring 21, the test arc block 22 is in firm contact with the thermal fuse 14, increasing the accuracy of the test. One side of the limiting column 19 is designed in a semi-circular shape, which is conducive to the circular thermal fuse 14 sliding in and out between the connecting plates 16, facilitating the taking and installation of the thermal fuse 14.

[0026] Working principle: When detecting the thermal fuse 14, place the thermal fuse 14 between the two connecting plates 16 on the ring plate 15, and press the thermal fuse 14. When the thermal fuse 14 moves closer to the axis of the rotating shaft 3, it squeezes the limiting column 19 to slide into the hole groove 23. When the thermal fuse 14 is in the final position, the limiting column 19 pops out under the action of the second spring 24 to fix the thermal fuse 14. Start the motor 8 to drive the runner 9 to rotate, and at the same time make the first connecting column 10 rotate eccentrically around the runner 9. Due to the restriction of the inner chute at the upper end of the T-shaped slide 7, when the first connecting column 10 rotates, it pushes the connecting rod 11, causing the slider 17 to move back and forth in the inner chute at the upper end of the T-shaped slide 7. When the upper side step 18 of the front end of the slider 17 contacts the tooth of the straight bevel gear 12, the straight bevel gear 12 rotates by the contact between the inclined surface of the step 18 and the front end of the tooth. At the same time, the inclined surface of the lower side step 18 at the rear end of the slider 17 is in contact with the bottom of the rear end of the tooth. At this time, the inclined surface of the upper side step 18 at the front end of the slider 17 contacts another tooth at the upper end of the tooth, realizing the intermittent rotation of the straight bevel gear 12, driving the intermittent rotation of the ring plate 15 and the connecting plate 16, and thus enabling the two sides of the thermal fuse 14 to have time to contact the test arc block 22 and display the test result on the display 5. The bottom of the test arc block 22 is in the shape of a downward parabola. When the two sides of the thermal fuse 14 move along the arc track of the test arc block 22, they squeeze the telescopic rod 20. Under the action of the first spring 21, the test arc block 22 can be in firm contact with the two sides of the thermal fuse 14. The motor 8 continues to rotate, and hold the middle part of the thermal fuse 14 and pull it outwards, squeezing the limiting column 19 to slide in the hole groove 23 again. At the same time, place a new thermal fuse 14 at the vacant position for detection, improving the working efficiency of the thermal fuse detection.
