Description

Technical Field

[0001] The present application relates to the technical field of gas stove sealing detection, and in particular to a gas stove sealing detection device. Background Art

[0002] Gas stove tightness testing is a key step to ensure the safety of gas use. By testing the airtightness of the gas path, gas leakage can be prevented and potential safety hazards can be avoided. Commonly used testing methods include soapy water method, pressure testing method and electronic testing method, as well as professional mechanical linkage testing devices to achieve an automated and efficient testing process. Regular tightness testing is essential to maintaining family safety.

[0003] The most common pressure detection method is a scientific method to detect whether a gas stove is leaking by applying a certain pressure. The specific operation is to fill the gas passage of the gas stove with air at a certain pressure, and then maintain this pressure for a period of time. By observing the pressure gauge to determine whether there is a leak, if the pressure drops during the test, it means that there may be a leak. This method can effectively detect the sealing performance of the gas stove and ensure safe use.

[0004] When testing the sealing of a gas stove by a pressure detection method, it is usually necessary to place the gas stove in a detection box and then pressurize the inside of the box to detect pressure changes. However, the sealing of the detection box mainly depends on the tight connection of the sealing door to isolate the gas stove from the external environment. However, this method has certain limitations. It only relies on the sealing door to maintain the sealing state of the detection box, which can easily cause air pressure leakage in actual operation, resulting in inaccurate detection results. The detection efficiency and accuracy need to be improved. For this reason, the present application provides a gas stove sealing detection device. Summary of the invention

[0005] The purpose of the present application is to solve the problem that only a sealing door is used to maintain the sealing state of the detection box, which is easy to cause air pressure leakage in actual operation and lead to inaccurate detection results. The present application provides a gas stove sealing detection device.

[0007] By adopting the above technical solution, the gas stove body is placed on the placement plate. At this time, the position of the gas stove body is limited and stabilized by the operation of the limiting mechanism to prevent the gas stove body from shaking, which helps to ensure that the connection between the pressure detector and the gas pipe is tight and leak-free, thereby improving the detection accuracy. At this time, the sealing cover can be closed to drive the sealing strip into the interior of the detection box and make the sealing strip fit the inner wall of the detection box, so as to achieve the seal between the detection box and the sealing cover.

In the process of waiting for the air pressure to change, the auxiliary mechanism can be started to operate through the display to spray soapy water on the outer wall of the gas pipe. In the process of spraying soapy water, the auxiliary mechanism can also be used to observe whether there are obvious bubbles on the outer wall of the gas pipe.

[0011] By adopting the above technical solution, since the inclined surface at one end of the interference rod fits with the inclined surface at one end of the connecting rod, the connecting rod will be squeezed to descend in the guide groove during the movement of the interference rod.

[0012] Furthermore, the auxiliary mechanism includes a screw rod rotatably connected to one side of the placement plate, a motor is fixedly connected to one side of the interior of the detection box, the output end of the motor is fixedly connected to one end of the screw rod, a threaded sleeve is threadedly connected to the screw rod, one side of the threaded sleeve is fixedly connected to a liquid storage tank, an arc-shaped splint is symmetrically fixedly connected to the liquid storage tank, and a plurality of atomizing nozzles are evenly fixedly connected to the inner wall of the arc-shaped splint.

[0015] By adopting the above technical solution, during the soapy water spraying process, the panoramic camera can also be used to directly observe whether there are obvious bubbles on the outer wall of the gas pipe. If so, it indicates that the gas pipe is broken and needs to be replaced in time to avoid gas leakage when the gas stove body is in use, which greatly improves the accuracy and diversity of the detection results.

[0016] Furthermore, the limiting mechanism includes a connecting column that is symmetrically and slidably connected to the placement plate, the top of the connecting column is fixedly connected to the connecting plate, the bottom of the connecting column is fixedly connected to a spring three, the other end of the spring three is fixedly connected to the inner wall of the placement plate, the inside of the placement plate is symmetrically and fixedly connected to a fixed block, the inside of each fixed block is slidably connected to a trapezoidal block, two limiting blocks are symmetrically and slidably connected on the placement plate, one end of the trapezoidal block is fixedly connected to the fixing plate, one side of the fixing plate is fixedly connected to a spring four, and the other end of the spring four is fixedly connected to the inner wall of the placement plate.

[0031] The following is combined with Figure 1-5 This application is described in further detail.

[0032] The embodiment of the present application discloses a gas stove sealing detection device.

[0033] Reference Figure 1 and Figure 2 A gas stove sealing detection device comprises a detection box 1, a sealing cover 2 is installed on the top of the detection box 1, a sealing strip 3 is fixedly connected to the bottom of the sealing cover 2, a placement plate 4 is fixedly connected to the inside of the detection box 1, a gas stove body 5 is arranged on the top of the placement plate 4, a gas pipe 6 is fixedly connected to one side of the gas stove body 5, a pressure detector 7 is fixedly connected to one side of the detection box 1, and the other end of the gas pipe 6 is connected to the pressure detector 7, chambers 8 are opened on both sides of the inside of the detection box 1, baffles 81 are fixedly connected to the inside of the chamber 8, a sealing mechanism 9 is installed in the chamber 8, a pressure sensor 10 is fixedly connected to one side of the detection box 1, an auxiliary mechanism 11 is installed on one side of the placement plate 4, a limiting mechanism 12 is installed inside the placement plate 4, a display 13 is fixedly connected to one side of the detection box 1, and the pressure sensor 10 is electrically connected to the display 13.

[0034] When in use, first open the sealing cover 2, then place the gas stove body 5 on the placement plate 4, and when the gas stove body 5 is pressed against the top of the placement plate 4, the limiting mechanism 12 will be triggered to operate according to the gravity of the gas stove body 5, and the position of the gas stove body 5 will be limited and stabilized by the operation of the limiting mechanism 12 to prevent the gas stove body 5 from shaking, which helps to ensure that the connection between the pressure detector 7 and the gas pipe 6 is tight and leak-free, thereby improving the detection accuracy, and then connect one end of the gas pipe 6 to the gas stove body 5 and the other end to the pressure detector 7. At this time, the sealing cover 2 can be closed to drive the sealing strip 3 to enter the interior of the detection box 1 and make the sealing strip 3 fit the inner wall of the detection box 1, so as to achieve the sealing between the detection box 1 and the sealing cover 2, and when the sealing strip 3 gradually enters the interior of the detection box 1, it will contact and squeeze the sealing mechanism 9, and at this time, after being squeezed by the sealing strip 3, the sealing mechanism 9 will be pushed out from the inside of the chamber 8, and the pushed-out sealing mechanism 9 can fit tightly with the bottom of the sealing strip 3, so as to seal the sealing strip 3 and the gap of the contact surface of the inner wall of the detection box 1 are sealed again, which greatly enhances the overall sealing effect of the detection box 1, reduces the risk of air pressure leakage in the detection box 1, and greatly improves the detection efficiency and accuracy. At this time, the air pressure inside the detection box 1 can be detected in real time through the cooperation of the pressure sensor 10 and the pressure detector 7 to determine whether there is a gas leakage in the gas stove body 5. If the pressure inside the detection box 1 drops during the test, it indicates that there may be a leakage. Therefore, this method can effectively detect the sealing performance of the gas stove body 5 to ensure safe use. In the process of waiting for the air pressure to change, the auxiliary mechanism 11 can be started through the display 13 to spray soap water on the outer wall of the gas pipe 6. In the process of spraying soap water, the auxiliary mechanism 11 can also be used to observe whether there are obvious bubbles on the outer wall of the gas pipe 6. If there are bubbles, it indicates that the gas pipe 6 is broken and needs to be replaced in time to avoid gas leakage when the gas stove body 5 is used, which greatly improves the accuracy and diversity of the detection results.

[0035] Reference Figure 2The sealing mechanism 9 includes a guide groove 91 symmetrically opened on one side of the inner part of the detection box 1, and a resisting rod 92 is slidably connected inside the guide groove 91. A guide groove 93 is opened through the top of the chamber 8, and a connecting rod 94 is slidably connected in the guide groove 93. A curved block 95 is fixedly connected to the bottom of the connecting rod 94, and a spring 96 is fixedly connected to the bottom of the curved block 95. The other end of the spring 96 is fixedly connected to the inner wall of the chamber 8. A sliding rod 97 is slidably connected to the baffle 81, and one end of the sliding rod 97 is fixedly connected to a connecting head 98. The connecting head 98 is in contact with one side of the curved block 95, and the sliding The other end of the moving rod 97 is fixedly connected to a sealing block 99, and a spring 2 910 is sleeved on the sliding rod 97. One end of the spring 2 910 is fixedly connected to one side of the connecting head 98, and the other end of the spring 2 910 is fixedly connected to one side of the baffle 81. One end of the resistance rod 92 is in an arc shape, and the other end of the resistance rod 92 is provided with a bevel. The end of the connecting rod 94 away from the curved block 95 is also provided with a bevel. The bevel at one end of the resistance rod 92 fits with the inclined surface at one end of the connecting rod 94. One side of the curved block 95 is in a curved arc shape, and the top of the spring 2 910 fits with the bottom of the sealing strip 3.

[0036] When in use, when the sealing strip 3 gradually enters the interior of the detection box 1, the bottom of the sealing strip 3 will contact the arc-shaped end of the resistance rod 92 and squeeze the resistance rod 92. According to the squeezing of the sealing strip 3, the resistance rod 92 will slide into the guide groove 91. Because the inclined surface of one end of the resistance rod 92 fits the inclined surface of one end of the connecting rod 94, the connecting rod 94 will be squeezed to descend in the guide groove 93 during the movement of the resistance rod 92, thereby pushing the curved block 95 to descend in the chamber 8 and squeeze the spring 96 to contract. Because one side of the curved block 95 is curved, it will make The raised end gradually squeezes one side of the connector 98, thereby pushing the connector 98 to drive the sliding rod 97 to slide on the baffle 81. After the raised end on one side of the curved block 95 is completely fitted with one side of the connector 98, the sliding rod 97 will push the sealing block 99 out of the chamber 8, so that the top surface of the sealing block 99 is closely fitted with the bottom surface of the sealing strip 3, so as to re-seal the gap between the contact surface of the sealing strip 3 and the inner wall of the detection box 1, which greatly enhances the overall sealing effect of the detection box 1, reduces the risk of air pressure leakage in the detection box 1, and greatly improves the detection efficiency and accuracy. Secondly, when the inspection is completed, the sealing cover 2 can be opened again. At this time, the inner wall of the sealing strip 3 will release the squeezing of one end of the resistance rod 92. According to the mutual rebound of the spring 1 96 and the spring 2 910, the curved block 95 will push the connecting rod 94 to reset inside the guide groove 93, so that the raised end of the curved block 95 is separated from one side of the connecting head 98. At this time, the connecting head 98 will drive the sliding rod 97 and the sealing block 99 to reset, so that the sealing block 99 returns to the inside of the chamber 8 to avoid affecting the subsequent removal of the gas stove body 5.

[0037] Reference Figure 2 and Figure 3 The auxiliary mechanism 11 includes a screw rod 111 rotatably connected to one side of the placement plate 4, a motor 112 is fixedly connected to one side of the inside of the detection box 1, the output end of the motor 112 is fixedly connected to one end of the screw rod 111, a threaded sleeve 113 is threadedly connected to the screw rod 111, one side of the threaded sleeve 113 is fixedly connected to a liquid storage tank 114, an arc-shaped clamping plate 115 is symmetrically fixedly connected to the liquid storage tank 114, and a plurality of atomizing nozzles 116 are evenly fixedly connected to the inner wall of the arc-shaped clamping plate 115, a guide rod 117 is fixedly connected to one side of the placement plate 4, the other end of the guide rod 117 is fixedly connected to the inner wall of the detection box 1, a connecting block 118 is slidably connected to the guide rod 117, one side of the connecting block 118 is fixedly connected to one side of the liquid storage tank 114, two panoramic cameras 119 are symmetrically fixedly connected to the liquid storage tank 114, and the two panoramic cameras 119 are evenly electrically connected to the display 13.

[0038] When in use, first pass the gas pipe 6 through the two arc-shaped clamping plates 115 and connect it to the pressure detector 7, then start the motor 112 to drive the screw rod 111 to rotate, and as the screw rod 111 rotates, the threaded sleeve 113 will move on the screw rod 111. At this time, according to the guidance of the guide rod 117 and the connecting block 118, the threaded sleeve 113 will drive the liquid storage tank 114 to move during the movement. As the liquid storage tank 114 moves, the two arc-shaped clamping plates 115 on the top will move along the gas pipe 6, and the atomizing nozzle 116 will be started during the movement to spray soapy water on the outer wall of the gas pipe 6. During the soapy water spraying process, the panoramic camera 119 can also be used to directly observe whether there are obvious bubbles on the outer wall of the gas pipe 6. If there are bubbles, it indicates that the gas pipe 6 is broken and needs to be replaced in time to avoid gas leakage when the gas stove body 5 is in use, thereby greatly improving the accuracy and diversity of the detection results.

[0039] Reference Figure 2 , Figure 4 and Figure 5The limiting mechanism 12 includes a connecting column 121 symmetrically penetrating and slidingly connected in the placement plate 4, a connecting plate 122 is fixedly connected to the top of the connecting column 121, a spring 123 is fixedly connected to the bottom of the connecting column 121, the other end of the spring 123 is fixedly connected to the inner wall of the placement plate 4, a fixed block 124 is symmetrically fixedly connected inside the placement plate 4, a trapezoidal block 125 is slidably connected inside the fixed block 124, two limiting blocks 126 are symmetrically penetrating and slidingly connected on the placement plate 4, and one end of the trapezoidal block 125 is fixedly connected to a fixed plate 128 A spring four 129 is fixedly connected to one side of the fixed plate 128, and the other end of the spring four 129 is fixedly connected to the inner wall of the placement plate 4. Both ends of the trapezoidal block 125 are inclined, and the bottom of the limit block 126 is inclined. A slider 127 is fixedly connected to the bottom of the limit block 126. A sliding groove corresponding to the size of the slider 127 is opened on the inclined surface of one end of the trapezoidal block 125, and the slider 127 is slidably connected in the sliding groove. A corner of the end of the trapezoidal block 125 away from the sliding groove is arc-shaped, and a corresponding arc groove 1291 is opened on one side of the connecting column 121.

[0040] When in use, the gas stove body 5 is placed on the placement plate 4. When the gas stove body 5 is pressed against the top of the placement plate 4, the gravity of the gas stove body 5 drives the connecting column 121 to slide into the placement plate 4. As the connecting column 121 moves, one side of the connecting column 121 squeezes the inclined surface of the trapezoidal block 125, thereby pushing the trapezoidal block 125 to slide in the fixed block 124 until the arc shape at one end of the trapezoidal block 125 enters the arc groove 1291. Because the slider 127 at the bottom end of the limit block 126 is slidably connected with the slide groove on one side of the trapezoidal block 125, when the trapezoidal block 125 slides, it squeezes the limit block 126 to rise, thereby The limit blocks 126 are pushed out from the inside of the placement plate 4. The multiple limit blocks 126 that are pushed out can be used to clamp and stabilize the two sides of the gas stove body 5 to prevent the gas stove body 5 from shaking, which helps to ensure that the connection between the pressure detector 7 and the gas pipe 6 is tight and leak-free, thereby improving the detection accuracy. Secondly, when the gas stove body 5 is taken out from the inside of the detection box 1 and away from the connecting plate 122, the spring four 129 and the spring three 123 will automatically rebound to push the connecting column 121 upward, and the trapezoidal block 125 will move in the fixed block 124. As the trapezoidal block 125 is reset, the limit block 126 will be driven back into the placement plate 4 to complete the automatic recovery.

[0041] The implementation principle of the gas stove sealing detection device of the present embodiment is as follows: when in use, first open the sealing cover 2, then place the gas stove body 5 on the placement plate 4, and when the gas stove body 5 is pressed against the top of the placement plate 4, the gravity of the gas stove body 5 will drive the connecting column 121 to slide into the placement plate 4, and as the connecting column 121 moves, one side of the connecting column 121 will squeeze the inclined surface of the trapezoidal block 125, thereby pushing the trapezoidal block 125 to slide in the fixed block 124, until the arc shape at one end of the trapezoidal block 125 enters the arc groove 1291, because the slider 127 at the bottom end of the limit block 126 is slidably connected with the sliding groove on one side of the trapezoidal block 125, when the trapezoidal block 125 slides, The limit block 126 is squeezed to rise, so as to push the limit block 126 out from the inside of the placement plate 4. The multiple limit blocks 126 that are pushed out can clamp and stabilize the two sides of the gas stove body 5 to prevent the gas stove body 5 from shaking, which helps to ensure that the connection between the pressure detector 7 and the gas pipe 6 is tight and leak-free, thereby improving the detection accuracy. Secondly, when the gas stove body 5 is taken out from the inside of the detection box 1 and away from the connecting plate 122, at this time, according to the mutual rebound of the spring four 129 and the spring three 123, the connecting column 121 is automatically pushed upward, and the trapezoidal block 125 is moved in the fixed block 124. As the trapezoidal block 125 is reset, the limit block 126 is driven back to the placement plate 4 to complete the automatic recovery; Then, one end of the gas pipe 6 is connected to the gas stove body 5, and the other end is connected to the pressure detector 7. At this time, the sealing cover 2 can be closed to drive the sealing strip 3 to enter the interior of the detection box 1 and make the sealing strip 3 fit with the inner wall of the detection box 1, so as to achieve the sealing between the detection box 1 and the sealing cover 2. When the sealing strip 3 gradually enters the interior of the detection box 1, the bottom of the sealing strip 3 will contact the arc shape of one end of the resistance rod 92 and squeeze the resistance rod 92. According to the squeezing of the sealing strip 3, the resistance rod 92 will slide into the guide groove 91. Because the inclined surface of one end of the resistance rod 92 fits with the inclined surface of one end of the connecting rod 94, the connecting rod 94 will be squeezed to descend in the guide groove 93 during the movement of the resistance rod 92, so as to push the curved block 95 to descend in the chamber 8 and squeeze the spring 1 96 to contract. Because one side of the curved block 95 is in a curved arc shape, the protruding end will gradually squeeze one side of the connecting head 98, so as to push the connecting head 98 to drive the sliding rod 97 to slide on the baffle 81. After the raised end of one side of the curved block 95 is completely fitted with one side of the connecting head 98, the sliding rod 97 will push the sealing block 99 out of the chamber 8, so that the top surface of the sealing block 99 is tightly fitted with the bottom surface of the sealing strip 3, so as to seal the gap between the contact surface of the sealing strip 3 and the inner wall of the detection box 1 again, which greatly enhances the overall sealing effect of the detection box 1, reduces the risk of air pressure leakage in the detection box 1, and greatly improves the detection efficiency and accuracy. Secondly, when the detection is completed, the sealing cover 2 can be opened again, at this time, the inner wall of the sealing strip 3 will release the pressure on one end of the resistance rod 92, and according to the mutual rebound of the spring 1 96 and the spring 2 910, the curved block 95 will push the connecting rod 94 to reset in the guide groove 93, so that the raised end of the curved block 95 is away from one side of the connecting head 98. At this time, the connecting head 98 will drive the sliding rod 97 and the sealing block 99 to reset, so that the sealing block 99 returns to the interior of the chamber 8 to avoid affecting the subsequent removal of the gas stove body 5. At this time, the pressure sensor 10 and the pressure detector 7 can be used to cooperate with each other to detect the air pressure inside the detection box 1 in real time to determine whether there is a gas leak in the gas stove body 5. If the pressure inside the detection box 1 drops during the test, it means that there may be a leak. Therefore, this method can effectively detect the sealing performance of the gas stove body 5 to ensure safe use. In the process of waiting for the air pressure to change, the display 13 can also be used to start the starter motor 112 to drive the screw rod 111 to rotate. As the screw rod 111 rotates, the threaded sleeve 113 moves on the screw rod 111. At this time, according to the guide rod 117 and the connecting block 11 8, the threaded sleeve 113 will drive the liquid storage tank 114 to move during the movement. As the liquid storage tank 114 moves, the two arc-shaped clamping plates 115 on the top will move along the gas pipe 6, and the atomizing nozzle 116 will be started during the movement to spray soapy water on the outer wall of the gas pipe 6. During the soapy water spraying process, the panoramic camera 119 can also be used to directly observe whether there are obvious bubbles on the outer wall of the gas pipe 6. If there are bubbles, it indicates that the gas pipe 6 is broken and needs to be replaced in time to avoid gas leakage when the gas stove body 5 is in use, thereby greatly improving the accuracy and diversity of the detection results.
