Description

Technical Field

[0001] This utility model relates to a testing device, specifically an impact testing device for the strength of an electric meter box. Background Technology

[0002] During the production process, the meter box needs to undergo impact testing to verify its strength. If the strength of the meter box fails to meet the requirements, the production process can be adjusted or the raw materials replaced in a timely manner to ensure that the finished product is qualified.

[0003] Patent application CN116337603A discloses an outdoor electric meter box strength tester, which includes a base, a support frame on the side of the base away from the ground, an impact mechanism, and a height adjustment mechanism. The impact mechanism includes a support beam located on the side of the support frame near the base, a collar located near the center of the support beam, a support column fitted inside the collar, an impact head at one end of the support column near the base, and a top block at the end of the support column away from the base. The height adjustment mechanism includes sliding columns on both sides of the support frame, a sliding seat slidably connected to the middle of the sliding column, rotating rods on both sides of the sliding seat, rotating rods rotatably connected to a slider, and the slider slidably connected to the sliding rods. This invention is applicable to an outdoor electric meter box strength tester. By setting a height adjustment mechanism, the impact head can move freely up and down. This tester can simultaneously perform impact resistance testing and pressure resistance testing of the electric meter box.

[0004] The aforementioned testing instrument, during impact testing, only detects the impact through the free fall of the impact head after interference between the impact head and the collar. The impact energy is constant, and the impact energy of the impact head on the tested object cannot be quantified and controlled. Therefore, it cannot specifically test meter boxes of different strengths and materials. Thus, it is necessary to redesign an impact testing device for meter box strength to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an impact detection device that can effectively control impact energy and specifically detect the strength of an electric meter box.

[0006] The technical solution of this utility model is:

[0009] The bottom end of the impact head of the puncture impactor is conical, while the bottom end of the impact head of the blunt impactor is flat.

[0010] A limiting groove is provided on the guide cylinder on one side of the scale; a lifting handle is threaded on the impact head, and the lifting handle extends through the limiting groove to the outside of the guide cylinder.

The longitudinal slide rail on one side of the crossbeam is movably connected to the slide of the piercing impactor, and the longitudinal slide rail on the other side of the crossbeam is movably connected to the slide of the blunt impactor. The portal frame is fixedly connected to the base.

[0014] Multiple sets of fixing screws are threaded in pairs on the base below the gantry frame, and a pad is provided on the inner end of the fixing screw.

[0015] The beneficial effects of this utility model are as follows:

[0016] This impact testing device for meter box strength can quantify the lifting height of the impact head via a scale, control the relative height between the impact head and the meter box under test, and thus quantify and control the impact energy of the impact head on the meter box. This allows for targeted impact testing of meter boxes with different strengths and materials, employing varying impact energies. The position adjustment mechanism allows for easy adjustment of the impact position, enabling targeted testing of different parts of the meter box. This solves the problem of existing testing instruments being unable to quantify and control impact energy, thus hindering targeted testing. Attached Figure Description

[0024] This impact testing device for the strength of an electrical meter box consists of a base 1, a position adjustment mechanism, a puncture impactor, and a blunt impactor. The puncture impactor and blunt impactor are mounted on the base 1 via the position adjustment mechanism. The puncture impactor is used to conduct a puncture test, assessing the strength of the meter box under test under impact from a sharp object; the blunt impactor is used to conduct a blunt impact test, assessing the strength of the meter box under test under blunt impact. The position adjustment mechanism adjusts the positions of the puncture impactor and blunt impactor, allowing them to deliver targeted impacts to different parts of the meter box under test, thus enabling targeted testing.

[0025] The piercing impactor and the blunt impactor are respectively composed of a slide block 2, a lifting slide rail 3, a guide cylinder 4, an impact head 5, and a scale 6. The lifting slide rail 3 is movably mounted on the slide block 2, and the guide cylinder 4 is mounted on the lifting slide rail 3. The impact head 5 is inserted into the guide cylinder 4. The impact head 5, through the conversion of potential energy into kinetic energy, impacts the meter box under test as it falls through the guide cylinder 4, thus performing the test. A scale 6 is set on the circumference of the guide cylinder 4 to read and control the height of the impact head 5 relative to the bottom end of the guide cylinder 4, thereby controlling the height of the impact head 5 relative to the meter box under test and controlling the impact energy of the impact head 5. This allows for targeted testing based on the type and strength of the meter box material, ensuring accurate testing and enabling timely adjustments to production processes or raw materials based on test results to guarantee product quality before shipment. The guide cylinder 4 guides the impact head 5 as it falls, preventing it from deviating during its descent and ensuring accurate impact positioning. The function of the lifting slide rail 3 is twofold: firstly, to adjust the height of the guide cylinder 4 so that the distance between the bottom port of the guide cylinder 4 and the base 1 is sufficient to place the meter box to be tested; secondly, by adjusting the height of the guide cylinder 4 through the lifting slide rail 3, the falling stroke of the impact head 5 can be adjusted, thereby adjusting the impact energy of the impact head 5.

[0026] The bottom end of the impact head 5 of the puncture impactor is conical, so that the meter box under test can be punctured and impacted through the bottom tip of the impact head 5. The bottom end of the impact head 5 of the blunt impact impactor is flat, so that the meter box under test can be blunted and impacted through the bottom end of the blunt impact impactor 5.

[0027] A limiting groove 7 is provided on the guide cylinder 4 on one side of the scale 6; a lifting handle 8 is threaded onto the impact head 5, extending through the limiting groove 7 to the outside of the guide cylinder 4. Positioning slots 9 are evenly distributed on the limiting groove 7. The function of the lifting handle 8 is to raise the height of the impact head 5, thereby enabling impact as the impact head 5 falls from a height. The function of the positioning slots 9 is to position the height of the impact head 5 by cooperating with the lifting handle 8, thus fixing the impact head 5 at a high position for easy adjustment of the impactor's position and simplifying the control of the impact energy. The function of the limiting groove 7 is to restrict the impact head 5 by cooperating with the lifting handle 8, ensuring that the impact head 5 does not easily detach from the guide cylinder 4.

[0028] Support plates 10 are respectively provided on the slide blocks 2 on both sides of the lifting slide rail 3. Set screws 11 for fixing the position of the lifting slide rail 3 are threaded on the support plates 10, so as to fix the height of the guide cylinder 4 by fixing the position of the lifting slide rail 3, thereby determining the impact energy of the impact head 5.

[0029] The position adjustment mechanism consists of a portal frame 12, transverse slide rails 13, a crossbeam 14, and longitudinal slide rails 15. The portal frame 12, arranged side-by-side, has transverse slide rails 13 on its top. A crossbeam 14 is movably mounted between the transverse slide rails 13, and longitudinal slide rails 15 are located on both sides of the crossbeam 14. One longitudinal slide rail 15 on one side of the crossbeam 14 is movably connected to the slide seat 2 of the piercing impactor, and the other longitudinal slide rail 15 on the other side of the crossbeam 14 is movably connected to the slide seat 2 of the blunt impactor. The portal frame 12 is fixedly connected to the base 1. The transverse slide rails 13 adjust the front-to-back position of the crossbeam 14, thereby adjusting the front-to-back position of the piercing impactor and the blunt impactor. The longitudinal slide rails 15 adjust the left-to-right position of the piercing impactor or the blunt impactor, thus cooperating with the transverse slide rails 13 to allow the piercing impactor or the blunt impactor to move to various positions above the base 1, thereby impacting various parts of the meter box to be tested.

[0030] Multiple sets of fixing screws 16 are installed in pairs on the base 1 below the gantry frame 12. The inner end of the fixing screw 16 is provided with a pad 17 so that the meter box under test can be clamped by the fixing screw 16 and the pad 17, thereby fixing the meter box under test on the base 1. This facilitates accurate testing of various parts of the meter box after positioning, and prevents the meter box from rebounding after collision and affecting the test results.

[0031] When the impact testing device for the strength of the meter box is working (taking puncture testing as an example), the meter box to be tested is placed on the base 1 with the test surface facing upwards, and fixed by the fixing screw 16. After the meter box is fixed, the crossbeam 14 and the slide 2 are pushed to adjust the position of the puncture impactor to the test position of the meter box. After the position of the puncture impactor is adjusted, the set screw 11 is loosened, and the height of the guide cylinder 4 is adjusted so that the bottom port of the guide cylinder 4 is in contact with the test surface of the meter box (if the lifting height of the impact head 5 exceeds the limit of the limit slide 7, the insufficient part is supplemented by adjusting the distance between the bottom port of the guide cylinder 4 and the test surface). After the height of the guide cylinder 4 is adjusted, the height of the impact head 5 is raised by lifting the handle 8. During the lifting process, the lifting height of the impact head 5 is controlled by the ruler 6 or the positioning bracket 9. After the impact head 5 is raised to the position, the impact head 5 is released, and the impact head 5 falls under its own weight to impact the test surface of the meter box. After the impact is completed, the strength is judged to be qualified by detecting the diameter of the impact hole at the impact location (for blunt impact, the distance between the farthest end of the crack and the center point is detected).

[0032] This impact testing device for meter box strength can quantify the lifting height of the impact head via scale 6, control the relative height between the impact head 5 and the meter box under test, and thus quantify and control the impact energy of the impact head 6 on the meter box. This allows for targeted impact testing of meter boxes with different strengths and materials, using different impact energies. The position adjustment mechanism allows for easy adjustment of the impact position, enabling targeted testing of various parts of the meter box. This solves the problem of existing testing instruments being unable to quantify and control impact energy, thus preventing targeted testing.
