Description

Technical Field

[0001] The utility model relates to the technical field of gas detection equipment, in particular to an indoor hanging gas detection alarm. Background Art

[0002] Gas detection is a technology used to determine the type, concentration and existence status of specific gases in the environment. This technology is widely used in industry, medical and other fields to ensure personnel safety, normal equipment operation and environmental protection. The continuous development of gas detection technology has made gas detection instruments more and more intelligent and convenient. Modern gas detection instruments usually have multiple functions, such as real-time monitoring, automatic calibration, etc., which greatly improves the efficiency and accuracy of gas detection. It should be noted that the choice of gas detection technology should be determined according to the specific application scenarios and needs.

[0003] When detecting indoor gas, we will choose to use an indoor hanging gas detection alarm to conduct real-time detection of indoor gas. It is a device used to monitor the concentration of specific gases in the environment and automatically send out an alarm signal when the gas concentration exceeds the preset safety threshold. It has a wide range of applications in industrial safety, environmental monitoring and other fields, and is of great significance for preventing dangerous situations such as gas leaks and poisoning.

[0004] Currently, when installing a gas detection alarm, the instrument is usually installed according to the location of the gas release source. The instrument needs to be 30-60cm away from the release source, and then its position is fixed with fixing parts. After the fixation is completed, the alarm threshold is set according to the actual situation to ensure that the alarm signal can be issued in time when the gas concentration exceeds the safety threshold.

[0005] However, when installing indoor suspended gas detector alarms, bolts, screws and other fixing parts are usually used to fix the position of the instrument. Therefore, it is inconvenient to adjust its height after installation, and it cannot adapt to the position of different gas release sources. It is also impossible to adjust the angle of the instrument according to the gas release source, resulting in reduced flexibility and thus affecting the detection of gas. Utility Model Content

[0006] Based on this, the purpose of the utility model is to provide an indoor suspended gas detection alarm to solve the current problem that when installing indoor suspended gas detector alarms, the position of the instrument is usually fixed by using fixing parts such as bolts and screws. Therefore, it is inconvenient to adjust its height after installation, and it cannot adapt to the position of different gas release sources. It is also impossible to adjust the angle of the instrument according to the gas release source, resulting in reduced flexibility, thereby causing technical problems for gas detection.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an indoor suspended gas detection alarm, comprising a mounting plate, wherein the four corners of the mounting plate are provided with positioning holes, the bottom of the mounting plate is fixedly connected with two groups of fixed rods, and the outer surfaces of the fixed rods are slidably connected with a movable plate, the bottom of the movable plate is fixedly connected with a movable rod, and the movable rod slides in the fixed rod, the bottom of the movable rod is hingedly connected with an instrument body, the bottom of the mounting plate is provided with a groove, and a group of storage shafts are rotatably connected in the groove, the outer surface of each of the storage shafts is fixedly connected with one end of a group of steel ropes, and the other ends of the steel ropes are respectively fixedly connected to the corresponding two sides of the movable plate, the outer surface of each of the storage shafts is slidably connected with a first gear, a second gear is meshed in the middle of a group of the first gears, and the second gear is connected to the output end of the motor through a shaft, the motor is placed in a silencer box, and the silencer box is fixedly connected to one side of the mounting plate.

[0008] By adopting the above technical scheme, when a group of first gears and second gears are meshed, the second gear can be driven by the motor to rotate forward and backward, and the first gear and the storage shaft can be synchronously driven to rotate forward and backward to realize the retraction and release of the steel rope, so that each movable plate moves up and down on the outer surface of the corresponding fixed rod, and the height of the instrument body can be adjusted. At the same time, when one of the first gears is meshed with the second gear, the second gear only synchronously drives one of the first gears and the corresponding storage shaft to rotate forward and backward. Therefore, when a group of steel ropes on the outer surface of the corresponding storage shaft are retracted and released, a group of movable plates can be synchronously driven to move up and down on the outer surface of the corresponding fixed rod, so that a group of movable plates drives one side of the instrument body to move up and down, so the angle of the instrument body can be adjusted. This structure can realize the adjustment of the height or angle of the instrument body by changing the position of the first gear, which is convenient for improving the flexibility of the instrument body, thereby detecting gases from different release sources.

[0009] The utility model is further configured that a group of limiting grooves are arranged in the outer surface of each of the fixed rods, and a limiting block matching the limiting groove is slidably connected in the limiting groove, and the limiting block is fixedly connected to the outer surface of the movable rod.

[0010] By adopting the above technical solution, the movement of the movable rod can be limited, thereby increasing the stability of the movable plate moving on the outer surface of the fixed rod, so that it can stably drive the instrument body to move.

[0011] The utility model is further configured such that a slide groove is provided on the outer surface of each storage shaft, and a slider is slidably connected in the slide groove, each slider is fixedly connected to one side of the corresponding first gear, a thread groove is provided on the top of each slide groove, and a bolt is threadedly connected in the thread groove, and the bottom of the bolt is rotatably connected to one side of the slider.

[0012] By adopting the above technical solution, when adjusting the angle of the instrument body, the position of the first gear on the outer surface of the storage shaft on the corresponding side can be adjusted according to the actual tilt angle required by the instrument body, so that it is misaligned with the second gear. Therefore, when the motor drives the second gear to rotate, the misaligned first gear cannot drive the storage shaft to rotate, but at this time the storage shaft on the other side drives the movable plate to move upward, so that the instrument body presents a slope structure, and the adjustment of the instrument angle can be completed, so that the instrument body can detect gases from different release sources.

[0013] The utility model is further configured that each of the movable plates is connected to the bottom of the mounting plate through a first spring, and the movable plate is connected to the outer surface of the fixing rod through a second spring.

[0014] By adopting the above technical solution, when the storage shaft reels the steel rope, the movable plate can be moved upward, thereby squeezing the first spring. Therefore, the first spring can buffer the movement of the movable plate and increase the stability of its movement. At the same time, when the storage shaft unfolds the steel rope, the movable plate can be driven to move downward by the gravity of the instrument body itself. Therefore, the second spring can buffer the movement of the movable plate, thereby increasing the stability of its movement.

[0015] The utility model is further configured that the outer surface of each storage shaft is provided with a partition.

[0016] By adopting the above technical solution, the orderliness of the steel rope retraction and release can be increased. Therefore, when the same group of steel ropes are retracted and released, it can be avoided that the steel ropes are crossed or confused with each other, thereby affecting the subsequent use of the steel ropes.

[0017] The utility model is further configured that one end of the connection between each of the steel ropes and the movable plate is configured as a "Y"-shaped structure.

[0018] By adopting the above technical solution, the stability of the connection between the steel rope and the movable plate can be increased, and at the same time, the tension of the steel rope can be dispersed, thereby improving the stability of the movement of the movable plate.

[0019] The utility model is further configured that the outer surface of the mounting plate is provided with a slot, and the first gear and the second gear move in the slot.

[0020] By adopting the above technical solution, the first gear and the second gear can be stably moved in the slot, thereby avoiding affecting the rotation of the first gear and the second gear.

[0021] In summary, the utility model mainly has the following beneficial effects:

[0022] The utility model can realize the retraction and extension of the steel rope by meshing the second gear and a group of first gear gears, and the positive and negative rotation of the second gear can drive the first gear and the storage shaft to rotate positively and negatively, so as to realize the retraction and extension of the steel rope, thereby making each movable plate slide on the outer surface of the corresponding fixed rod, and the height of the instrument body can be adjusted. At the same time, when one of the first gears is meshed with the second gear, the second gear drives one of the first gears and the storage shaft to rotate, so the retraction and extension of a group of steel ropes on the outer surface of the storage shaft can synchronously drive a group of movable plates to move up and down on the outer surfaces of the corresponding fixed rods, so that a group of movable plates drives one side of the instrument body to move up and down, so the angle of the instrument body can be adjusted. This structure can realize the adjustment of the height or angle of the instrument body by changing the position of the first gear, which is convenient for improving the flexibility of the instrument body, thereby detecting gases from different release sources.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0029] The following describes an embodiment of the utility model based on its overall structure.

[0030] An indoor hanging gas detection alarm, such as Figure 1-4As shown, it includes a mounting plate 1 , and positioning holes 2 are arranged at the four corners of the mounting plate 1 . The position of the mounting plate 1 can be fixed by arranging fixing parts in the positioning holes 2 .

[0031] Then, two groups of fixed rods 3 are fixedly connected to the bottom of the mounting plate 1, and the outer surface of the fixed rod 3 is slidably connected to a movable plate 8, the bottom of the movable plate 8 is fixedly connected to a movable rod 4, and the movable rod 4 slides in the fixed rod 3, and the bottom of the movable rod 4 is hingedly connected to the instrument body 5. When the movable plate 8 slides on the outer surface of the fixed rod 3, the movable rod 4 can be synchronously driven to slide in the fixed rod 3, thereby moving the position of the instrument body 5. A groove 11 is provided at the bottom of the mounting plate 1, and a group of storage shafts 12 are rotatably connected in the groove 11. One end of a group of steel ropes 13 is fixedly connected to the outer surface of each storage shaft 12, and the other end of the steel rope 13 is respectively It is fixedly connected to the corresponding two sides of the movable plate 8, and the steel rope 13 is retracted and released through the storage shaft 12, which synchronously drives the movable plate 8 to move. The outer surface of each storage shaft 12 is slidably connected with a first gear 15, and a second gear 20 is meshed in the middle of a group of first gears 15, and the second gear 20 is connected to the output end of the motor 21 through the shaft. When the motor 21 drives the second gear 20 to rotate, it can synchronously drive the first gear 15 meshed with the second gear 20 to rotate. The motor 21 is placed in a silencer box 22, and the silencer box 22 is fixedly connected to one side of the mounting plate 1. The position of the motor 21 can be fixed by the silencer box 22.

[0032] Wherein each movable plate 8 is connected to the bottom of the mounting plate 1 through a first spring 9, and the movable plate 8 is connected to the outer surface of the fixed rod 3 through a second spring 10. When the storage shaft 12 reels the steel rope 13, the pulling force of the steel rope 13 drives the movable plate 8 to move upward, thereby squeezing the first spring 9. Therefore, the first spring 9 can buffer the movement of the movable plate 8 and increase the stability of its movement. At the same time, when the storage shaft 12 unfolds the steel rope 13, the movable plate 8 can be driven to move downward by the gravity of the instrument body 5 itself. Therefore, the second spring 10 can buffer the movement of the movable plate 8, thereby increasing the stability of its movement.

[0033] Therefore, when in use, by providing a second gear 20 and a group of first gears 15 meshing with the second gear 20, the steel rope 13 can be retracted and released when the second gear 20 rotates forward and backward to drive the first gear 15 and the storage shaft 12 to rotate forward and backward, so that each movable plate 8 moves up and down on the outer surface of the corresponding fixed rod 3, and the height of the instrument body 5 can be adjusted. At the same time, when one of the first gears 15 is meshed with the second gear 20, the second gear 20 only synchronously drives one of the first gears 15 and the corresponding storage shaft 12 to rotate forward and backward. Therefore, the retraction and release of a group of steel ropes 13 on the outer surface of the corresponding storage shaft 12 can synchronously drive a group of movable plates 8 to move up and down on the outer surface of the corresponding fixed rod 3, so that a group of movable plates 8 drives one side of the instrument body 5 to move up and down, so the angle of the instrument body 5 can be adjusted. This structure can realize the adjustment of the height or angle of the instrument body 5 by changing the position of the first gear 15, which is convenient for improving the flexibility of the instrument body 5, thereby detecting gases from different release sources.

[0034] A group of limiting grooves 6 are further provided in the outer surface of each fixed rod 3, and a limiting block 7 matching the limiting groove 6 is slidably connected in the limiting groove 6. The limiting block 7 is fixedly connected to the outer surface of the movable rod 4, and the sliding of the movable rod 4 in the fixed rod 3 can be limited by the limiting grooves 6 and the limiting block 7, thereby increasing the stability of the movable plate 8 sliding on the outer surface of the fixed rod 3. At the same time, a sliding groove 16 is provided on the outer surface of each storage shaft 12, and a slider 17 is slidably connected in the sliding groove 16. Each slider 17 is fixedly connected to one side of the corresponding first gear 15. A threaded groove 18 is provided at the top of each sliding groove 16, and a bolt 19 is threadedly connected in the threaded groove 18. The bottom of the bolt 19 is rotatably connected to one side of the slider 17, and the bolt 19 can be moved in the threaded groove 18 by the bolt 19, so that the synchronous slider 17 moves in the sliding groove 16, so that the corresponding first gear 15 can be driven to move on the outer surface of the storage shaft 12, thereby adjusting its position.

[0035] In this embodiment, the stability of the connection between each steel rope 13 and the movable plate 8 is improved, and the tension of the steel rope 13 is dispersed, thereby improving the stability of the movement of the movable plate 8. One end of the connection between each steel rope 13 and the movable plate 8 is set to a "Y"-shaped structure, which can increase the steel rope 13 and a partition plate 14 is provided on the outer surface of each storage shaft 12. The partition plate 14 can reduce the crossing or confusion of a group of steel ropes 13 on the outer surface of each storage shaft 12 when they are retracted or released, so the movable plate 8 can be better driven by the steel rope 13 to encounter. At the same time, a groove 23 is provided on the outer surface of the mounting plate 1, and the first gear 15 and the second gear 20 are movable in the groove 23, so that the rotation of the first gear 15 and the second gear 20 can be avoided due to the mounting plate 1. The outer surface of the first gear 15 and the second gear 20 is lower than the top of the mounting plate 1, so the installation of the device can be avoided.
