A rubber seal ring strength detection device

Abstract

This utility model discloses a rubber sealing ring strength testing device, belonging to the field of rubber sealing ring testing technology. It solves the problem that existing devices are inconvenient for detecting the magnitude of the force when a rubber ring breaks, and that when the rubber ring breaks, it flies out in all directions, easily causing injury to workers. The device includes a base, a vertical plate fixedly installed on the right side of the top surface of the base, a groove formed in the middle of the front side wall of the vertical plate, a protective component on the front side of the vertical plate, and a detection component positioned between the vertical plate and the protective component. With the detection component, when the rubber ring is pulled, it compresses the fixed plate, and the pressure on the fixed plate is transmitted to a pressure sensor through a connecting plate, allowing the measurement of the pressure on the fixed plate, and thus the tensile force on the rubber ring. The protective component, using a U-shaped plate and a movable door, prevents the broken rubber ring from flying out in all directions, thus protecting the testing personnel.

Description

Technical Field

[0001] This utility model relates to the field of rubber sealing ring testing technology, specifically a rubber sealing ring strength testing device. Background Technology

[0002] In ensuring the reliability of sealing systems, rubber seals are core components, and their performance and quality directly determine the sealing effect. Strength, as a key indicator of a rubber seal's service life, is crucial for ensuring stable operation under complex conditions such as high pressure and alternating loads. Scientific testing of tensile length can effectively assess the seal's resistance to deformation during installation and use.

[0003] A search revealed that patent application number 202421842629.6 discloses a strength testing device for rubber sealing rings. This utility model includes a rectangular base plate, on which a limiting mechanism and a fixing mechanism are provided. Two support plates are fixedly connected to the top of the rectangular base plate, and a bidirectional threaded rod is rotatably connected between the two support plates. The right side of the bidirectional threaded rod rotatably passes through the outer wall of the right support plate and extends to the outside. Two moving blocks are threadedly connected to the outer wall of the bidirectional threaded rod. Although the rubber seal strength testing equipment improves the ease of installation by incorporating a fixing mechanism—utilizing spring compression and the position of the fixing rod to initially and effectively secure the seal and prevent displacement or detachment during subsequent operations—it cannot accurately record the peak force data at the moment of material breakage in real time. This results in significant errors in the strength test results, making it difficult to meet the requirements of high-precision quality control. Furthermore, when the rubber seal breaks, the instantaneous release of elastic potential energy causes fragments to scatter at high speed, posing a potential safety threat. This scattering can cause physical injuries to operators' eyes and skin, and may also lead to secondary problems such as scratches on the equipment surface and sensor damage, severely impacting the safety and continuity of the testing work.

[0004] Therefore, we propose a rubber seal strength testing device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a rubber sealing ring strength testing device, which solves the problem that existing devices are inconvenient for detecting the magnitude of the force when the rubber ring breaks, and that when the rubber ring breaks, it will fly in all directions, which can easily cause injury to workers.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a rubber sealing ring strength testing device, including a base, a vertical plate fixedly installed on the right side of the top surface of the base, a sliding groove opened in the middle of the front side wall of the vertical plate, a protective component provided on the front side of the vertical plate, and a testing component provided between the vertical plate and the protective component; The detection assembly includes a motor fixedly installed on the bottom surface of the slide groove. A threaded rod is fixedly connected to the output end of the motor. A slider that is slidably fitted inside the slide groove is threaded onto the outer surface of the threaded rod. A semi-circular tension plate is provided on the front side of the slider. A pressure sensor is provided on the front side of the top of the vertical plate. A semi-circular fixing plate corresponding to the position of the tension plate is provided above the pressure sensor.

[0007] Preferably, the tension plate and the fixing plate have the same specifications, and both the tension plate and the fixing plate have arc-shaped grooves on their arc surfaces, so as to facilitate the rubber ring to be fitted inside the arc-shaped grooves and to limit the position of the rubber ring.

[0008] Preferably, a lower horizontal plate is fixedly installed in the middle of the front side of the slider, and the tension plate is fixedly installed on the bottom surface of the lower horizontal plate, wherein the tension plate is supported by the lower horizontal plate.

[0009] Preferably, an upper horizontal plate is fixedly installed on the front side of the top of the base, a pressure sensor is fixedly installed on the top surface of the upper horizontal plate, a connecting plate is fixedly installed on the top surface of the pressure sensor, and the fixing plate is fixedly installed on the top surface of the connecting plate. The pressure on the fixing plate is transmitted to the pressure sensor through the connecting plate, and then the pressure on the fixing plate is measured by the pressure sensor.

[0010] Preferably, a pressure display and a controller are fixedly installed on the left and right sides of the top surface of the base, respectively. The pressure sensor is connected to the pressure display, and the motor is connected to the controller. The pressure display shows the measurement results of the pressure sensor, which is existing technology and will not be described in detail here. The controller controls the start and stop of the motor, which is existing technology and will not be described in detail here.

[0011] Preferably, the protective component includes a U-shaped plate fixedly installed in the middle of the front side of the base. The front side of the U-shaped plate is hinged to a movable door. An observation port is provided in the middle of the U-shaped plate. A transparent glass is embedded inside the observation port. The protective component can prevent the rubber ring from breaking and flying everywhere, which could cause injury to the testing personnel. The transparent glass makes it easy to observe the degree of stretching of the rubber ring.

[0012] This invention provides a rubber sealing ring strength testing device. It has the following beneficial effects: 1. This rubber sealing ring strength testing equipment, through the setting of the testing components, can place the rubber ring on a tension plate and a fixed plate, and then move the tension plate downward to pull the rubber ring. The rubber ring then squeezes the fixed plate, and the pressure on the fixed plate is transmitted to the pressure sensor through the connecting plate. The pressure on the fixed plate can be measured, and then the tensile force on the rubber ring can be known. When the rubber ring breaks, the maximum pressure measured by the pressure sensor is displayed on the pressure display, so the ultimate tensile force that the rubber ring can withstand can be known. This greatly facilitates the detection of the tensile force on the rubber ring and solves the problem that existing devices are not convenient for detecting the magnitude of the force when the rubber ring breaks. 2. This rubber seal ring strength testing equipment, through the setting of protective components, can use U-shaped plates and movable doors to prevent the rubber ring from flying everywhere after breakage, thus protecting the testing personnel. In addition, the transparent glass makes it easy to observe the degree of stretching of the rubber ring, solving the problem that in existing devices, the rubber ring will fly in all directions when it breaks, which can easily cause injury to the staff.

Detailed Implementation

[0015] 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.

[0016] Example 1: As Figure 1-4As shown: A base 1 is included, and a vertical plate 2 is fixedly installed on the right side of the top surface of the base 1. A groove 21 is formed in the middle of the front sidewall of the vertical plate 2. A protective component 5 is provided on the front side of the vertical plate 2, and a detection component is provided between the vertical plate 2 and the protective component 5. The detection component includes a motor 6 fixedly installed on the bottom surface of the groove 21. A threaded rod 7 is fixedly connected to the output end of the motor 6. A slider 8, which is slidably fitted inside the groove 21, is threaded onto the outer surface of the threaded rod 7. A semi-circular tension plate 10 is provided on the front side of the slider 8. The top of the vertical plate 2... A pressure sensor 12 is installed on the front side of the base 1. Above the pressure sensor 12 is a semi-circular fixed plate 14 corresponding to the position of the tension plate 10. The tension plate 10 and the fixed plate 14 have the same specifications. Both the tension plate 10 and the fixed plate 14 have arc-shaped grooves 15 on their arc surfaces. A lower horizontal plate 9 is fixedly installed in the middle of the front side of the slider 8. The tension plate 10 is fixedly installed on the bottom surface of the lower horizontal plate 9. An upper horizontal plate 11 is fixedly installed on the front side of the top of the base 1. The pressure sensor 12 is fixedly installed on the top surface of the upper horizontal plate 11. A connecting plate 13 is fixedly installed on the top surface of the pressure sensor 12, and a fixing plate 14 is fixedly installed on the top surface of the connecting plate 13. A pressure display 3 and a controller 4 are fixedly installed on the left and right sides of the top surface of the base 1, respectively. The pressure sensor 12 is connected to the pressure display 3, and the motor 6 is connected to the controller 4. By setting the detection components, the rubber ring can be put on the tension plate 10 and the fixing plate 14, and then the tension plate 10 can be moved downward to pull the rubber ring. Then the rubber ring squeezes the fixing plate 14, and the pressure on the fixing plate 14 is transmitted to the pressure sensor 12 through the connecting plate 13. The pressure on the fixing plate 14 can be measured, and then the tension on the rubber ring can be known. When the rubber ring breaks, the pressure display 3 displays the maximum pressure measured by the pressure sensor 12, and the ultimate tensile force that the rubber ring can withstand can be known. This makes it easier to detect the tensile force on the rubber ring and solves the problem that existing devices are not convenient to detect the magnitude of the force when the rubber ring is broken. Example 2: Figure 1-2 As shown: The protective component 5 includes a U-shaped plate 51 fixedly installed in the middle of the front side of the base 1. A movable door 52 is hinged to the front side of the U-shaped plate 51. An observation port is opened in the middle of the U-shaped plate 51, and a transparent glass 53 is embedded inside the observation port. By setting up the protective component 5, the U-shaped plate 51 and the movable door 52 can prevent the rubber ring from flying everywhere after it breaks, which can protect the testing personnel. The transparent glass 53 makes it easy to observe the degree of the rubber ring being stretched, which solves the problem that the rubber ring will fly in all directions when the existing device breaks, which can easily cause injury to the staff.

[0017] The working principle and usage process of this utility model: When using this rubber sealing ring strength testing equipment, open the movable door 52, then put the top end of the rubber ring into the arc-shaped groove 15 on the fixed plate 14, and then put the bottom end of the rubber ring into the arc-shaped groove 15 on the tension plate 10. Then start the motor 6 to drive the threaded rod 7 to rotate, which can make the slider 8, the lower horizontal plate 9 and the tension plate 10 move downward along the side wall of the slide groove 21, and then pull the rubber ring. The rubber ring will be pulled downward and squeeze the fixed plate 14. Then the connecting plate 13 transmits the pressure on the fixed plate 14 to the pressure sensor 12. Then the pressure sensor 12 measures the tension on the rubber ring until the rubber ring is broken. Then the pressure display 3 displays the ultimate tensile force that the rubber ring can withstand. The protective component 5 can prevent the broken rubber ring from flying everywhere, thus protecting the testing personnel.
