Description

Technical Field

[0001] This utility model relates to the field of medical pressurization, and in particular to a digital display and pressure detector. Background Technology

[0002] A pressure detector is a device used to measure the pressure of a gas or liquid, and it is widely used in industries such as manufacturing, automotive, and medical.

[0003] During medical pressurization, the tubing is connected and secured to the connecting tube on the outer casing. The pressure sensor inside the casing then detects the pressure and converts the pressure signal into an electrical signal using piezoelectric, piezoresistive, and capacitive principles. The pressure data is then output to the digital display screen, and an alarm light will illuminate if the pressure is too high or too low. When other tubing is connected to the connecting tube on the outer casing, the connection point is prone to loosening after repeated high-pressure impacts. This can reduce the seal at the connection point, affecting the performance of the pressure detector. Utility Model Content

[0004] The technical problem this invention aims to solve is that when other pipes are connected to the outer casing of the connecting pipe, the connection point is prone to loosening after being subjected to multiple high-pressure impacts. This loosening leads to a decrease in the sealing performance of the connecting pipe connection, which in turn affects the performance of the pressure detector.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a pressure detector, including a housing and a fixing component. A connecting pipe is provided on one side of the housing, a digital display screen is provided on one side of the housing, and several alarm lights are provided on one side of the housing. A sealing device is provided on the side of the housing near the connecting pipe by means of the fixing component. The sealing device improves the sealing performance of the connection between the connecting pipe and other pipes through a rubber ring.

[0006] The aforementioned components achieve the following effects: During medical inflation, the fixing assembly secures the sealing device to the side of the housing near the connecting tube, then connects and fixes the tube to the connecting tube on the housing, and then seals the connection point using the sealing device. The pressure sensor inside the housing detects the pressure and converts the pressure signal into an electrical signal using piezoelectric, piezoresistive, and capacitive principles. The pressure data is then output to the digital display screen, and an alarm light will be activated if the pressure is too high or too low.

[0007] Preferably, the sealing device includes a slide rail, a sliding block, and a rubber ring. The rubber ring moves inside the slide rail via the sliding block. A fixing band wrapped around the surface of the rubber ring is provided on one side of the sliding block. Several through holes are opened on the side of the fixing band away from the sliding block. A first bolt passes through the through holes on the surface of the fixing band and reaches inside the sliding block to fix the fixing band.

[0008] The effect achieved by the above components is as follows: Before the connecting pipe is connected to other pipes, the fixing component fixes the slide rail to the side of the outer shell near the connecting pipe, and the rubber ring is located on the side of the connecting pipe near the outer shell, with the inner wall of the rubber ring fitting against the connecting pipe. After the connecting pipe is connected to other pipes, the rubber ring is moved upwards to the connection point. At this time, the rubber ring drives the sliding block fixed on one side to slide inside the slide rail. Then, the fixing band fixed to the sliding block is pulled, so that the fixing band wraps around the surface of the rubber ring, and the rubber ring is better pressed against the connection point of the connecting pipe and other pipes. Then, the first bolt is rotated so that the first bolt passes through the through hole on the surface of the fixing band and reaches the inside of the sliding block for threaded fixing, thus completing the fixing of the fixing band position. Then, the rubber ring is fixed to the connection point of the connecting pipe and other pipes for sealing. By using the sealing device, the connection point of the connecting pipe and other pipes can be sealed, preventing the connection point of the connecting pipe from loosening after being subjected to multiple high-pressure impacts, which would lead to a decrease in the sealing performance of the connection point, thereby improving the performance of the pressure detector.

[0009] Preferably, a control frame is provided on one side of the fixing belt, and the control frame increases the dimension of one side of the fixing belt.

[0010] The effect achieved by the above components is to increase the size of one side of the fixed belt by fixing the control frame on one side of the fixed belt, making it easier for the operator to pull the fixed belt.

[0011] Preferably, a plurality of anti-slip blocks are provided on one side of the first bolt, and the plurality of anti-slip blocks increase the friction on one side of the first bolt.

[0012] The effect achieved by the above components is to increase the friction between the first bolt and the operator by fixing several anti-slip blocks on one side of the first bolt, making the first bolt easier to rotate.

[0013] Preferably, the slide rail is provided with a reinforcing rod that penetrates the sliding block, and the reinforcing rod enhances the connection strength between the slide rail and the sliding block.

[0014] The effect achieved by the above components is as follows: by fixing a reinforcing rod inside the slide rail and allowing the reinforcing rod to slide through the sliding block, the connection strength between the sliding block and the slide rail is improved, making it less likely for the sliding block to detach from the slide rail when it slides.

[0015] Preferably, the fixing assembly includes a second bolt, a fixing plate, and a washer. The fixing plate is disposed on one side of the slide rail, and the second bolt passes through the washer and the fixing plate to reach the inside of the housing to fix the fixing plate.

[0016] The effect achieved by the above components is as follows: when sealing the device, the slide rail with the fixed plate is placed on the side of the housing near the connecting pipe, and then the second bolt is rotated so that the second bolt passes through the gasket and the fixed plate, and is then threaded and fixed to the housing. The second bolt abuts against the gasket, and then the fixed plate and the slide rail are quickly fixed. By using the fixing components, the sealing device can be quickly fixed on the side of the housing near the connecting pipe, which facilitates the subsequent use of the sealing device.

[0017] Preferably, the outer casing is provided with a positioning block on the side near the fixing plate, and the positioning block positions the fixing plate.

[0018] The effect achieved by the above components is to quickly position the fixing plate on the outer shell by means of the positioning block fixed on the outer shell surface, so as to facilitate the subsequent use of the second bolt to fix the fixing plate.

[0019] Preferably, a digital display employs a pressure detector as described in any one of claims 1-7.

[0020] In summary, the beneficial effects of this utility model are as follows:

[0021] By using a sealing device, the connection between the connecting pipe and other pipes can be sealed, preventing the connection from loosening after repeated high-pressure impacts, which would reduce the sealing performance of the connection and thus improve the effectiveness of the pressure detector.

[0022] By using the fixing components, the sealing device housing can be quickly fixed close to the connecting pipe, thus facilitating subsequent use of the sealing device. Attached Figure Description

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] Example 1, Figures 1 to 4 The pressure detector shown includes a housing 1 and a fixing assembly 6. A connecting pipe 2 is located on one side of the housing 1, a digital display screen 3 is located on another side of the housing 1, and several alarm lights 4 are located on yet another side of the housing 1. A sealing device 5 is located on the side of the housing 1 near the connecting pipe 2, secured by the fixing assembly 6. The sealing device 5 uses a rubber ring 53 to improve the sealing at the connection between the connecting pipe 2 and other pipes. During medical inflation, the fixing assembly 6 secures the sealing device 5 to the side of the housing 1 near the connecting pipe 2, then connects and fixes the pipe to the connecting pipe 2 on the housing 1. The sealing device 5 then seals the connection. A pressure sensor inside the housing 1 detects the pressure and converts the pressure signal into an electrical signal using piezoelectric, piezoresistive, and capacitive principles. The pressure data is then output to the surface of the digital display screen 3. An alarm is triggered by the alarm lights 4 when the pressure is too high or too low.

[0032] Figures 1 to 4The sealing device 5 shown includes a slide rail 51, a sliding block 52 and a rubber ring 53. The rubber ring 53 moves inside the slide rail 51 via the sliding block 52. A fixing band 54 is provided on one side of the sliding block 52 and wrapped around the surface of the rubber ring 53. Several through holes 56 are provided on the side of the fixing band 54 away from the sliding block 52. A first bolt 55 passes through the through holes 56 on the surface of the fixing band 54 and reaches inside the sliding block 52 to fix the fixing band 54. Before connecting pipe 2 is connected to other pipes, fixing assembly 6 fixes slide rail 51 to the side of housing 1 near connecting pipe 2, and rubber ring 53 is located on the side of connecting pipe 2 near housing 1, with the inner wall of rubber ring 53 fitting against connecting pipe 2. After connecting pipe 2 is connected to other pipes, rubber ring 53 is moved upwards to the connection point. At this time, rubber ring 53 drives sliding block 52 fixed on one side to slide inside slide rail 51. Then, fixing strap 54 fixed to sliding block 52 is pulled, causing fixing strap 54 to wrap around the surface of rubber ring 53, and making rubber ring 53 better press against connecting pipe 2. At the connection with other pipes, the first bolt 55 is rotated so that it passes through the through hole 56 on the surface of the fixing band 54 and reaches the inside of the sliding block 52 for threaded fixing, thus fixing the position of the fixing band 54. Then, the rubber ring 53 is fixed to the connection between the connecting pipe 2 and other pipes for sealing. By using the sealing device 5, the connection between the connecting pipe 2 and other pipes can be sealed, preventing the connection of the connecting pipe 2 from loosening after being subjected to multiple high-pressure impacts, which would reduce the sealing performance of the connection of the connecting pipe 2, thereby improving the performance of the pressure detector.

[0033] Figures 1 to 4 A control frame 57 is provided on one side of the fixing strap 54, which increases the size of one side of the fixing strap 54. By fixing the control frame 57 to one side of the fixing strap 54, the size of one side of the fixing strap 54 is increased, making it easier for the operator to pull the fixing strap 54. Several anti-slip blocks 58 are provided on one side of the first bolt 55, which increases the friction on one side of the first bolt 55. By fixing several anti-slip blocks 58 to one side of the first bolt 55, the friction between the first bolt 55 and the operator is increased, making the first bolt 55 easier to rotate. A reinforcing rod 59 is provided inside the slide rail 51, penetrating the sliding block 52. The reinforcing rod 59 increases the connection strength between the slide rail 51 and the sliding block 52. By fixing the reinforcing rod 59 inside the slide rail 51 and allowing the reinforcing rod 59 to slide through the sliding block 52, the connection strength between the sliding block 52 and the slide rail 51 is increased, making it less likely for the sliding block 52 to detach from the slide rail 51 when sliding.

[0034] Figures 1 to 4The fixing assembly 6 shown includes a second bolt 61, a fixing plate 62, and a washer 63. The fixing plate 62 is disposed on one side of the slide rail 51. The second bolt 61 passes through the washer 63 and the fixing plate 62 to reach the interior of the outer casing 1 to fix the fixing plate 62. When sealing the device 5, the slide rail 51 with the fixing plate 62 is placed on the side of the outer casing 1 near the connecting pipe 2. Then, the second bolt 61 is rotated so that it passes through the washer 63 and the fixing plate 62, and is then threaded onto the outer casing 1. The second bolt 61 abuts against the washer 63, thus quickly fixing the fixing plate 62 to the slide rail 51. By using the fixing assembly 6, the sealing device 5 can be quickly fixed on the side of the outer casing 1 near the connecting pipe 2, thus facilitating subsequent use of the sealing device 5. A positioning block 64 is provided on the side of the outer casing 1 near the fixing plate 62. The positioning block 64 positions the fixing plate 62. The positioning block 64 fixed to the surface of the outer casing 1 quickly positions the fixing plate 62 on the outer casing 1, thus facilitating subsequent fixing of the fixing plate 62 using the second bolt 61.

[0035] Working principle: During medical pressurization, the fixing component 6 fixes the sealing device 5 to the side of the outer shell 1 near the connecting pipe 2, and then connects and fixes the pipe to the connecting pipe 2 on the outer shell 1. Then, the sealing device 5 is used to seal the connection between the two. Then, the pressure detection sensor inside the outer shell 1 detects the pressure and converts the pressure signal into an electrical signal through the principles of piezoelectricity, piezoresistive force, and capacitance. Then, the pressure data is output on the surface of the digital display screen 3, and an alarm will be triggered by the alarm light 4 when the pressure is too high or too low. Before connecting pipe 2 is connected to other pipes, fixing assembly 6 fixes slide rail 51 to the side of housing 1 near connecting pipe 2, and rubber ring 53 is located on the side of connecting pipe 2 near housing 1, with the inner wall of rubber ring 53 fitting against connecting pipe 2. After connecting pipe 2 is connected to other pipes, rubber ring 53 is moved upwards to the connection point. At this time, rubber ring 53 drives sliding block 52 fixed on one side to slide inside slide rail 51. Then, fixing strap 54 fixed to sliding block 52 is pulled, causing fixing strap 54 to wrap around the surface of rubber ring 53, and making rubber ring 53 better press against connecting pipe 2. At the connection with other pipes, the first bolt 55 is rotated so that it passes through the through hole 56 on the surface of the fixing band 54 and reaches the inside of the sliding block 52 for threaded fixing, thus fixing the position of the fixing band 54. Then, the rubber ring 53 is fixed to the connection between the connecting pipe 2 and other pipes for sealing. By using the sealing device 5, the connection between the connecting pipe 2 and other pipes can be sealed, preventing the connection of the connecting pipe 2 from loosening after being subjected to multiple high-pressure impacts, which would reduce the sealing performance of the connection of the connecting pipe 2, thereby improving the performance of the pressure detector.

[0036] When sealing device 5, slide rail 51 with fixed plate 62 is placed on the side of housing 1 near connecting pipe 2. Then, the second bolt 61 is rotated so that the second bolt 61 passes through gasket 63 and fixed plate 62, and is then threaded to housing 1. The second bolt 61 abuts against gasket 63. Then, the fixed plate 62 and slide rail 51 are quickly fixed in position. By using fixing component 6, sealing device 5 can be quickly fixed on the side of housing 1 near connecting pipe 2, which facilitates subsequent use of sealing device 5.
