AI Technical Summary
Existing fire extinguisher quality testing equipment uses a relatively fixed testing direction, which leads to localized stress concentration on the outer wall of the fire extinguisher. This makes it difficult to synchronously compress the entire fire extinguisher, which can easily cause the fire extinguisher to shift during testing and reduce the stability of the test results.
A fire extinguisher quality testing device was designed, comprising a squeezing section and a fixing section. The squeezing blocks are driven by a hydraulic cylinder to move along the sliding block. Multiple squeezing blocks move synchronously toward the center to uniformly squeeze the outer wall of the fire extinguisher. The fire extinguisher is fixed by a clamping block driven by a motor to prevent shaking or displacement and ensure the stability of the testing process.
This method achieves uniform compression of the outer wall of the fire extinguisher, avoids displacement caused by localized force, improves the stability and applicability of the test results, and ensures the accuracy of the test data.

Description
Technical Field
[0001] This utility model belongs to the field of fire alarm technology, and in particular relates to a fire extinguisher quality testing device. Background Technology
[0002] Fire extinguisher quality testing equipment is a professional instrument used to test whether the various performance indicators of fire extinguishers meet the standards. Testing the quality of fire extinguishers is to ensure that they can be used normally in the event of a fire. If the fire extinguisher has insufficient pressure, poor sealing, or insufficient structural strength, it will affect the fire extinguishing effect and may even pose a safety hazard during use. Regular testing can promptly identify problems and repair or replace them, ensuring that the fire extinguishers are in good condition and providing effective protection for fire safety.
[0003] However, existing testing equipment has a relatively fixed testing direction, and the force on the outer wall of the fire extinguisher is concentrated in a local area, making it difficult to synchronously squeeze the entire fire extinguisher. The localized force can cause the fire extinguisher to deviate during the test, reducing the stability of the test results. Utility Model Content

By setting up a squeezing part, it solves the problems of existing testing devices having a relatively fixed testing direction, concentrated local stress on the outer wall of the fire extinguisher, difficulty in synchronously squeezing the entire fire extinguisher, and local stress causing the fire extinguisher to deviate during testing, thus reducing the stability of the test results.

[0007] Furthermore, the fixing part includes a connecting assembly mounted on the top of the fixing frame; and a clamping assembly mounted on the connecting assembly.
[0008] Furthermore, the testing assembly includes a hydraulic cylinder disposed between two connecting plates, a pressure gauge mounted on the hydraulic cylinder, and a test piece disposed on the slide plate; wherein, the hydraulic cylinder passes through the two connecting plates, and both connecting plates are fixedly connected to the outer wall of the hydraulic cylinder, the testing assembly is powered by the hydraulic cylinder to push the extrusion block to move and extrude pressure on the outer wall of the fire extinguisher; the pressure gauge is used to monitor the pressure value in real time during the extrusion process.
[0009] Furthermore, the connecting assembly includes several limiting plates fixedly connected to the top of the fixing frame. A motor frame is fixedly connected to the right side of the fixing frame, and a fixing rod is provided between the two limiting plates located on the front side. The fixing rod passes through the two limiting plates located on the front side, and the outer wall of the fixing rod is fixedly connected to the two limiting plates located on the front side.

[0011] Furthermore, the test piece includes several extrusion blocks disposed on a slide plate, several connecting rods disposed on the slide plate, and movable plates fixedly connected to the outer walls of each of the connecting rods; wherein, there are three extrusion blocks, each of which is slidably connected to the inner walls of three slide blocks; there are three connecting blocks, each of which is slidably connected to the inner walls of three slide blocks; several connecting rods are distributed and slidably connected to several slide openings on the slide plate; several movable plates pass through several extrusion blocks, each of which is slidably connected to the inner walls of several extrusion blocks; several movable plates pass through several connecting blocks, each of which is slidably connected to the inner walls of several connecting blocks; and the extrusion block near the pressure gauge is fixedly connected to the output shaft of the hydraulic cylinder.

Several extrusion blocks cooperate with the connecting block, driving the moving plate to move along the slide block under the action of the hydraulic cylinder. At the same time, the connecting rod moves in the slide opening of the slide plate. Several moving plates slide on the inner wall of the extrusion block and the connecting block, so that the extrusion blocks move closer to each other, thereby extruding the outer wall of the fire extinguisher placed in the middle of the slide plate. When conducting fire extinguisher quality testing, multiple extrusion blocks move towards the center simultaneously, forming uniform extrusion on the outer wall of the fire extinguisher, avoiding localized force that may cause the fire extinguisher test to deviate, and improving the stability of the test results.

[0029] A specific application of this embodiment is as follows: During use, the hydraulic cylinder 221 is activated, pushing the pressing block 223 on it to move along the sliding block 214. Several pressing blocks 223 cooperate with several connecting blocks 224, and several moving plates 226 move along the sliding blocks 214 under the movement of the hydraulic cylinder 221. While the pressing blocks 223 and connecting blocks 224 move, the connecting rod 225 moves in the sliding groove on the sliding plate 213. The moving plates 226 slide against the inner walls of the pressing blocks 223 and connecting blocks 224, causing the pressing blocks 223 to move closer together, pressing against the outer wall of the fire extinguisher placed in the middle of the sliding plate 213 until the outer wall of the fire extinguisher is broken. Oops, when the hydraulic cylinder is working, pressure gauge 222 is activated. Pressure gauge 222 is an Elec TE2000 pointer-type pressure gauge. Its working principle is based on the principle of elastic element deformation under force. The measured pressure causes the elastic element to displace, which is amplified and transmitted through mechanical structures such as connecting rods and gears, driving the pointer to deflect on the scale, thereby directly displaying the pressure value and realizing the detection and reading of pressure. This completes the outer wall inspection of the fire extinguisher. Before inspecting the fire extinguisher, motor 321 is activated. Motor 321 drives the bidirectional threaded rod 322 to rotate. When the bidirectional threaded rod 322 rotates, the two moving blocks 323 and the two clamping blocks 324 cooperate with each other and move relative to each other along the fixed rod 313 until the two clamping blocks 324 fix the fire extinguisher.
