Description

Technical Field

[0001] The utility model belongs to the technical field of rubber seal ring strength detection, and particularly relates to a rubber seal ring strength detection device. Background Technique

[0002] In modern industry, rubber seal rings are widely used in various fields, such as automobiles, aerospace, petrochemical, machinery manufacturing, etc. They play a crucial role in the sealing system, can prevent the leakage of liquids and gases, and ensure the normal operation and working efficiency of equipment. However, the performance and quality of rubber seal rings directly affect the sealing effect. As one of the key performance indicators of rubber seal rings, the detection of strength becomes particularly important. Among them, the tensile length is a key indicator reflecting the flexibility and elasticity of rubber seal ring materials. By detecting the tensile length, the basic mechanical properties of the material can be understood, and it can be judged whether it meets the requirements of specific applications.

[0003] However, during the use of existing rubber seal ring strength detection equipment, it is not convenient for precise alignment and positioning, which will lead to deviations in the initial measurement points. During the stretching process, this deviation will be amplified, resulting in inaccurate tensile length data obtained from the final measurement, and it is not convenient to truly reflect the actual tensile performance of the seal ring. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a rubber seal ring strength detection device. By setting a limiting mechanism, it solves the problem that it is not convenient for precise alignment and positioning, which will lead to deviations in the initial measurement points. During the stretching process, this deviation will be amplified, resulting in inaccurate tensile length data obtained from the final measurement, and it is not convenient to truly reflect the actual tensile performance of the seal ring.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a rubber seal ring strength detection device, including a rectangular bottom plate, and a limiting mechanism and a fixing mechanism are arranged on the rectangular bottom plate;

[0007] Two support plates are fixedly connected to the top of the rectangular bottom plate. A bidirectional threaded rod is rotatably connected between the two support plates. The right side of the bidirectional threaded rod rotatably penetrates the outer wall of the support plate on the right side and extends to the outside. Two moving blocks are threadedly connected to the outer wall of the bidirectional threaded rod. A sliding rod is fixedly connected between the two support plates. The sliding rod slidably penetrates the two moving blocks. A motor is fixedly connected to the extended part on the right side of the bidirectional threaded rod. The limiting mechanism includes support plates two respectively fixedly connected to the tops of the two moving blocks.

[0008] Further, rectangular grooves are formed in both of the second support plates, and trapezoidal sliding grooves are formed in the inner walls of the front and rear sides of the two rectangular grooves.

[0009] Further, two sliding plates are slidably connected to the inner walls of several of the trapezoidal sliding grooves, and third support plates are fixedly connected to the mutually remote sides of the two second support plates.

[0010] Further, threaded rods are rotatably connected to the tops of the two third support plates. The two threaded rods respectively thread through the outer walls of the two sliding plates and extend to the outside, and handle ones are fixedly connected to the top side extension parts of the two threaded rods.

[0011] Further, the fixing mechanism includes a first fixing component and a second fixing component. The first fixing component includes fourth support plates respectively fixedly connected to the mutually close sides of the two second support plates, and sleeves are fixedly connected to the tops of the two fourth support plates.

[0012] Further, circular sliding pieces are slidably connected to the inner walls of the two sleeves, fixing rods are fixedly connected to the bottoms of the two circular sliding pieces, the bottom parts of the two fixing rods respectively slide out of the sleeves, the two fixing rods respectively slide through the outer walls of the two fourth support plates and extend to the outside, and the two fixing rods respectively slide through the outer walls of the two sliding plates and extend to the outside.

[0013] Further, the second fixing component includes pull rods respectively fixedly connected to the tops of the two circular sliding pieces.

[0014] Further, handle twos are fixedly connected to the tops of the two pull rods, and rubber sealing ring bodies are sleeved on the two fixing rods.

[0015] The utility model has the following beneficial effects:

[0016] By arranging the limiting mechanism, after the sleeving is completed, turn the handle one, the handle one drives the threaded rod to rotate, so that the sliding plate in the rectangular groove slides upward in the trapezoidal sliding groove until it contacts with the rubber sealing ring body, so as to prevent it from shifting, twisting or sliding during the stretching process, so as to ensure that the stretching force is uniformly applied along the predetermined direction and obtain an accurate stretching length measurement result;

[0017] By setting up a fixing mechanism, when it is necessary to fix the rubber sealing ring, one of the handles two can be pulled. The handle two drives the fixing rod on the circular sliding piece to move upward through the pull rod until the fixing rod is located above the sliding plate. At this time, the spring is in a compressed state. The rubber sealing ring body is sleeved on the secondary fixing rod, and then the other handle two is pulled to sleeve the other end of the rubber sealing ring body on the other fixing rod. Releasing the handle two completes the preliminary fixing of the rubber sealing ring body, enabling the position adjustment of the fixing rod to be achieved by pulling the handle two. The operation is simple and intuitive without complex steps, greatly improving the convenience of installing the rubber sealing ring on the device. By utilizing the compression force of the spring and the position of the fixing rod, the rubber sealing ring body can be preliminarily and effectively fixed to ensure that the sealing ring will not easily shift or fall off during subsequent operations.

The operation is simple and intuitive without complex steps, greatly improving the convenience of installing the rubber sealing ring on the device. By using the compression force of the spring 322 and the position of the fixing rod 314, the rubber sealing ring body 324 can be preliminarily and effectively fixed to ensure that the sealing ring will not easily shift or fall off during subsequent operations. After the sleeving is completed, turn the first handle 207. The first handle 207 drives the threaded rod 206 to rotate, so that the sliding plate 204 in the rectangular groove 202 slides upward in the trapezoidal sliding groove 203 until it contacts the rubber sealing ring body 324, which can prevent it from shifting, twisting or sliding during the stretching process, so as to ensure that the tensile force is evenly applied along the predetermined direction and an accurate tensile length measurement result is obtained. After completing the above steps, start the motor 105. The motor 105 drives the bidirectional threaded rod 102 to rotate, so that the two moving blocks 103 move away from each other under the action of the sliding rod 104 until the motor 105 is turned off when the rubber sealing ring body 324 breaks. Measuring the distance between the two moving blocks 103 can obtain the ultimate stretchable length of the rubber sealing ring body 324.
