Abstract
Description
Technical Field
[0001] This utility model relates to the field of balance testing instruments, specifically an environmental protection testing instrument. Background Technology
[0002] Testing instruments are widely used in daily production and life. However, in some environments, they are subjected to external vibrations, which can damage internal components and affect their normal performance. Existing testing instruments generally only use structures such as rubber pads to reduce vibration-induced damage. However, after absorbing vibration energy, rubber pads cannot quickly rebound to their initial state, resulting in a significant decrease in their shock absorption effect under continuous vibration, thus affecting the overall performance of the testing instrument. Utility Model Content
[0003] The purpose of this invention is to provide an environmental protection testing instrument to solve the problems mentioned in the background art.
[0004] To solve the above-mentioned technical problems, this utility model provides an environmental protection testing instrument, including a testing instrument body and a base plate. The base plate is located below the testing instrument body. A first mounting block is rotatably connected to the bottom of the testing instrument body, and a square hole is provided on the first mounting block. An arc-shaped plate is installed on the inner wall of the square hole, and the outer wall of the arc surface of the arc-shaped plate abuts against the bottom of the testing instrument body. The cross-section of the arc-shaped plate is a C-shaped pivot, which is located at the end of the first mounting block away from the testing instrument body. A second mounting plate is hinged to the first mounting block through the pivot. The second mounting plate is also provided with a square hole and an arc-shaped plate. The end of the second mounting plate away from the first mounting block is rotatably connected to a fixed block on the top of the base plate. A torsion spring is located between the first mounting block and the second mounting plate. The torsion spring is sleeved on the pivot, and the two ends of the torsion spring are respectively connected to the first mounting block and the second mounting plate.
[0005] Furthermore, a damper and a shock-absorbing spring are fixedly installed between the tester body and the base plate, with the shock-absorbing spring sleeved on the outer wall of the damper.
[0006] Furthermore, the material of the arc-shaped plate is spring steel.
[0007] Furthermore, the first mounting blocks are evenly distributed at the four corners of the bottom of the tester body.
[0008] Furthermore, the arc-shaped outer wall of the arc-shaped plate installed on the second mounting plate abuts against the top of the base plate.
[0009] Furthermore, a handle is fixedly installed on the top of the tester body, and a sponge layer is sleeved on the outer wall of the handle.
[0010] Furthermore, a rubber layer is installed on the bottom of the base plate, and the rubber layer is evenly distributed on the four sides of the bottom of the base plate.
[0011] Furthermore, the first mounting block and the second mounting plate are arranged symmetrically.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] In this invention, when external vibration or impact acts on the base plate, the vibration energy is transmitted to the first mounting block and the second mounting plate, causing them to rotate relative to each other around the pivot. The torsion spring is compressed or stretched, absorbing some of the energy. The C-shaped design of the arc plate allows it to elastically deform, further absorbing energy and preventing vibration from being transmitted to the tester body. After the torsion spring vibrates, it quickly rebounds, causing the first mounting block and the second mounting plate to return to their original positions, ensuring that the shock-absorbing and buffering structure can continuously withstand multiple vibrations or impacts. Through the synergistic effect of the arc plate and the torsion spring, external vibration is effectively isolated, the tester body remains stable, and the damage of vibration to the tester body is greatly reduced.

[0019] 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.
[0020] Please see Figures 1-4 This utility model provides a technical solution:
[0021] An environmental protection testing instrument includes a testing instrument body 1 and a base plate 2. The base plate 2 is located below the testing instrument body 1. A first mounting block 3 is rotatably connected to the bottom of the testing instrument body 1, and a square hole 4 is provided on the first mounting block 3. An arc-shaped plate 5 is installed on the inner wall of the square hole 4, and the outer wall of the arc surface of the arc-shaped plate 5 abuts against the bottom of the testing instrument body 1. The cross-section of the arc-shaped plate 5 is C-shaped. A rotating shaft 6 is located at the end of the first mounting block 3 away from the testing instrument body 1. A second mounting plate 8 is hinged to the first mounting block 3 through the rotating shaft 6. The second mounting plate 8 is also provided with a square hole 4 and an arc-shaped plate 5. The end of the second mounting plate 8 away from the first mounting block 3 is rotatably connected to a fixed block on the top of the base plate 2. A torsion spring 7 is located between the first mounting block 3 and the second mounting plate 8. The torsion spring 7 is sleeved on the rotating shaft 6, and the two ends of the torsion spring 7 are respectively connected to the first mounting block 3 and the second mounting plate 8.
[0022] When not subjected to external vibration or impact, the tester body 1 remains stably connected to the base plate 2 via the first mounting block 3 and the second mounting plate 8. The torsion spring 7 is in its natural state and does not deform, and the outer wall of the arc-shaped plate 5 is in close contact with the bottom of the tester body 1, ensuring the stability of the tester body 1.
[0023] When external vibration or impact acts on the base plate 2, the vibration energy is transmitted to the first mounting block 3 and the second mounting plate 8. Since the first mounting block 3 and the second mounting plate 8 are hinged by the pivot 6 and are respectively provided with arc-shaped plates 5, the vibration energy will cause the first mounting block 3 and the second mounting plate 8 to rotate relative to each other around the pivot 6. At this time, the torsion spring 7 is compressed or stretched, absorbing part of the vibration energy.
[0024] The C-shaped cross-section design of the arc plate 5 allows it to undergo elastic deformation when subjected to vibration, further absorbing vibration energy. The outer arc surface of the arc plate 5 remains in contact with the bottom of the tester body 1, ensuring that vibration energy is not directly transmitted to the tester body 1, thereby reducing vibration damage to the tester body 1.
[0025] During vibration, the torsion spring 7 absorbs energy through deformation and quickly rebounds to its initial state after the vibration ends, causing the first mounting block 3 and the second mounting plate 8 to return to their original positions. This rapid rebound characteristic enables the shock-absorbing structure to continuously and effectively cope with multiple vibrations or impacts.
[0026] Through the elastic deformation of the arc plate 5 and the energy absorption and rebound effect of the torsion spring 7, external vibrations and impacts are effectively isolated, and the test instrument body 1 remains stable, ensuring that the measurement accuracy is not disturbed. At the same time, this structural design can adapt to vibrations of different frequencies, and has a particularly good absorption effect on high-frequency vibrations.
[0027] See Figure 1A damper 9 and a shock-absorbing spring 10 are fixedly installed between the tester body 1 and the base plate 2. The shock-absorbing spring 10 is sleeved on the outer wall of the damper 9.
[0028] The damper 9 and the shock-absorbing spring 10 work together. The damper 9 is mainly used to absorb and dissipate vibration energy, while the shock-absorbing spring 10 buffers the impact force through elastic deformation. The combination of the two can more effectively reduce the impact of external vibration and impact on the test instrument body 1.
[0029] The damping spring 10 provides excellent buffering for low-frequency vibrations, while the damper 9 effectively absorbs high-frequency vibrations. This combined design enables the environmental testing instrument to handle a wider range of vibration frequencies, significantly improving its vibration damping performance.
[0030] See Figure 1-3 The material of the curved plate 5 is spring steel.
[0031] Spring steel has excellent elastic properties, which can undergo elastic deformation when subjected to external vibration or impact, absorb energy, and quickly return to its original shape after the vibration ends. This characteristic allows the arc plate 5 to be reused many times without easily suffering fatigue damage, thus extending its service life.
[0032] See Figure 1 The first mounting blocks 3 are evenly distributed at the four corners of the bottom of the tester body 1.
[0033] The first mounting block 3, as part of the shock absorption and buffer structure, is evenly distributed at the four corners, which can more effectively absorb vibration and impact energy from different directions, ensuring that the test instrument body 1 maintains stable operation in complex environments and reducing measurement errors.
[0034] See Figure 1-3 The arc-shaped outer wall of the arc plate 5, which is installed on the second mounting plate 8, abuts against the top of the base plate 2.
[0035] The arc-shaped outer wall of the arc plate 5 abuts against the top of the base plate 2, which can absorb energy through elastic deformation when subjected to external vibration or impact, reduce the vibration transmitted to the test instrument body 1, and thus improve the shock absorption and buffering effect.
[0036] See Figure 1 A handle 11 is fixedly installed on the top of the tester body 1, and a sponge layer is sleeved on the outer wall of the handle 11.
[0037] The sponge layer is fitted onto the outer wall of the handle 11, which increases the friction of the handle 11 and prevents the user from accidentally dropping the instrument due to slippage during handling. At the same time, the softness of the sponge layer also improves the comfort of holding the instrument and reduces hand fatigue during long-term operation.
[0038] See Figure 1A rubber layer 12 is installed on the bottom of the base plate 2, and the rubber layer 12 is evenly distributed on the four sides of the bottom of the base plate 2.
[0039] The rubber layer 12 has high friction, which can effectively prevent the environmental protection tester from sliding on the workbench, ensuring that the instrument remains stable during the measurement process and avoiding measurement errors or instrument tipping caused by sliding.
[0040] The rubber layer 12 has good elasticity and can absorb external vibration and impact energy, reducing the vibration transmitted to the instrument body 1, thereby improving the instrument's shock absorption performance and ensuring measurement accuracy.
[0041] See Figure 1-3 The first mounting block 3 and the second mounting plate 8 are symmetrically arranged.
[0042] The symmetrical arrangement of the first mounting block 3 and the second mounting plate 8 enables the weight of the tester body 1 and the external impact force to be evenly distributed to both sides, avoiding excessive local stress, thereby improving the stability and durability of the overall structure.
[0043] The first mounting block 3 and the second mounting plate 8 are symmetrically arranged, which can absorb vibration and impact energy from different directions more evenly, ensuring that the tester body 1 maintains stable operation in complex environments.
[0044] In addition, there are no restrictions on the specific type of the test instrument body 1. For example, it can be a test instrument for environmental performance testing, or even a pressure tester, a damping tester, etc.
