Description

Technical Field

[0001] This utility model relates to the field of impact testing technology, specifically to a testing device for the impact resistance performance of furniture. Background Technology

[0002] With the development of the modern furniture industry, consumers have placed higher demands on the safety and durability of furniture. Furniture may encounter various impacts during daily use, such as during transport and collisions, which can affect its structural stability, surface integrity, and even cause damage. Therefore, how to accurately and scientifically test the impact resistance of furniture has become a key focus for furniture manufacturers and quality inspection departments.

[0003] Currently, the testing methods for furniture impact resistance mainly rely on gravity impact tests. This involves dropping weights or cones of gravity freely from different heights and impacting the furniture surface to assess the damage after impact. While this type of testing is simple and easy to implement, it also has certain limitations, specifically in the following aspects:

[0004] Impact energy is difficult to adjust: In traditional gravity impact tests, the magnitude of the impact energy is mainly determined by the mass of the gravity block and the height of fall, making it difficult to control precisely and unable to simulate the actual conditions under different types of impacts. It cannot meet the testing needs of furniture made of different materials and with different designs.

[0005] Lack of consistency in test results: Because it is difficult to maintain consistency in each test during free fall impact testing, the test results may be affected by a variety of factors, such as the irregularity of the object surface and the different impact angles, thus affecting the comparability and stability of the test results.

[0006] Therefore, existing furniture impact resistance testing devices have some limitations, and there is an urgent need for a new type of testing device that can provide more accurate, stable, and diverse testing methods to better simulate the effects of different types of impacts on furniture, and provide a more scientific and reliable basis for furniture design and production. Utility Model Content

[0007] This utility model relates to a testing device for the impact resistance performance of furniture, aiming to provide a testing device that can accurately control impact energy and simulate various impact situations that furniture may encounter in actual use. Through the organic combination of energy storage mechanism, adjustment mechanism, positioning and locking device and magnetic adsorption function, this utility model can efficiently, stably and reliably conduct impact resistance performance testing of furniture.

[0008] To achieve the above objectives, the present invention provides a testing device for the impact resistance of furniture, comprising the following main components:

[0009] The trigger holder: As the main structure of the entire testing device, it provides support and control. An adjusting sleeve is fixedly installed on the surface of the trigger holder to adjust the initial position of the straight guide rail within the trigger holder and ensure its fixation.

[0010] Straight guide rail: One end of the straight guide rail is connected to the hair clip holder, and the other end is fixedly installed with the hair accumulator component. The straight guide rail is provided with a sliding groove to guide the sliding path of the upper winding clip, ensuring that the hair accumulator component can be smoothly adjusted during the sliding process.

[0011] The power storage assembly includes a winding box, a winding reel, and a rigid cord. The winding box is fixed to the surface of a straight guide rail, and the winding reel is mounted inside the winding box and driven by a spring. The rigid cord passes around the winding reel and accumulates the energy required for the impact through an energy storage mechanism, providing the driving force for subsequent impacts.

[0012] Impact pin: The impact pin is a ferromagnetic component that can be stably fixed during testing through magnetic attraction and positioning. The impact pin slides along a straight guide rail and releases energy to impact the surface of the test furniture, simulating the actual impact resistance test process.

[0013] In a preferred embodiment, this utility model can be further configured as follows:

[0014] Adjustment mechanism: By adjusting the grooves on the surface of the sleeve, combined with the positioning components, users can easily adjust the initial position of the energy storage component, thereby precisely controlling the energy storage stroke and impact energy.

[0015] Locking mechanism: When the straight guide rail slides to the designated position, the positioning component mechanically locks to ensure that the position does not change unexpectedly, thus guaranteeing the accuracy and repeatability of the test.

[0016] Limiting and guiding: The movement path of the impact pin is effectively limited during the test by the cooperation of the limiting groove and the limiting ear, ensuring stability and safety during the impact process.

[0017] Magnetic control: The magnetic buckle uses magnetic principles to attract and fix the impact pin, ensuring the accuracy and safety of initial positioning. The magnetic buckle's attraction function effectively prevents the impact pin from falling off during energy storage, enhancing the system's reliability.

[0018] Elastic spring drive: As an energy storage and driving component, the spring provides sufficient stability and reliability. Its elastic design ensures the uniformity and consistency of energy release in each test, avoiding the influence of energy fluctuations during impact.

[0019] The beneficial effects achieved by this utility model are as follows:

[0020] 1. Highly efficient energy storage and release: Through the design of the spring and roller, the storage and release of energy can be precisely controlled, making the magnitude and speed of impact energy adjustable, which meets the diverse impact resistance testing requirements of furniture.

[0021] 2. Stability and safety: The magnetic buckle positioning and reset device ensures the stability of the impact pin throughout the process, avoiding accidental detachment or misoperation and improving safety.

[0022] 3. High adjustability: Through the design of the adjustment sleeve and positioning components, the initial position of the power generation component can be flexibly adjusted according to different testing requirements, and the magnitude and timing of the impact energy release can be precisely controlled.

[0023] 4. Diverse impact modes: This device can simulate various impact modes in real-world usage scenarios, providing more diverse options for testing the impact resistance of furniture and improving the authenticity and reliability of the test.

[0024] The furniture impact resistance testing device provided in this embodiment achieves a highly efficient, adjustable, stable and reliable impact resistance testing system through the organic combination of energy storage mechanism, adjustment mechanism, positioning and locking device and magnetic adsorption function, and has broad application prospects.

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0035] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0036] The following is in conjunction with the appendix Figures 1-5 This invention describes a testing device for the impact resistance of furniture, provided by some embodiments of the present invention.

[0037] This embodiment provides a testing device for the impact resistance of furniture, such as... Figure 1 As shown. The testing device includes main components such as a hair clip holder 100, a straight guide rail 200, a hair storage assembly 300, and an impact pin 400. These components are interconnected and work together to form a complete impact testing system.

[0038] An adjusting sleeve 110 is fixedly installed on the surface of the hair clip holder 100. The adjusting sleeve is used to adjust the initial position of the straight guide rail 200 in the hair clip holder and to ensure that it is fixed.

[0039] One end of the straight guide rail 200 is connected to the hair clip holder 100, and the other end is fixedly mounted with the hair storage assembly 300. The straight guide rail is provided with a sliding groove to guide the sliding path of the upper winding clip 230.

[0040] The energy storage assembly includes a winding box 310, a winding reel 320, and a rigid rope 330. The winding box 310 is fixed to the surface of the straight guide rail 200, and the winding reel 320 is mounted inside the winding box 310 and driven by a spring 311. The rigid rope 330 passes around the winding reel 320 and accumulates the energy required for the impact through an energy storage method.

[0041] The impact pin 400 is a ferromagnetic component that can be stably fixed during testing by being attracted and positioned by the magnetic buckle 130. With the help of the magnetic buckle 130, the impact pin 400 slides along the straight guide rail 200 and eventually releases energy, simulating the impact situation of actual furniture.

[0042] Working principle and usage process:

[0043] Initial setup: When the testing device is ready, first adjust the initial position of the straight guide rail 200 using the adjusting sleeve 110 to ensure that the energy storage assembly 300 is in the appropriate energy storage position. At this time, the magnetic buckle 130 fixes the impact pin 400 in the initial position through adsorption.

[0044] Energy storage process: Control button 120 is used to start the test process. After starting, by operating control button 120, the spring 311 begins to work, transferring energy to the winding wheel 320. The winding wheel 320 begins to rotate, driving the rigid rope 330 to pull, and the energy storage assembly 300 stores energy.

[0045] Impact process: When the energy in the power storage component 300 reaches a predetermined value, the magnetic buckle 130 releases the impact pin 400 and guides it to slide along the straight guide rail 200 through the sliding guide groove, finally impacting the surface of the test furniture to simulate the actual impact resistance test process.

[0046] Adjustment and control: Through the positioning component, the user can adjust the sliding position of the straight guide rail 200 according to the test requirements, thereby adjusting the energy storage stroke of the energy storage component and further controlling the magnitude of the impact force.

[0047] Impact pin release and reset: After the impact is completed, the impact pin 400 returns to its initial position via the reset device and is ready for the next test.

[0048] Among them, the adjustment mechanism and the working principle of positioning lock are as follows:

[0049] Adjustment mechanism: By adjusting the groove on the surface of the sleeve 110, combined with the positioning component, the user can easily adjust the initial position of the energy storage component, thereby precisely controlling the energy storage stroke and impact energy.

[0050] Locking mechanism: When the straight guide rail 200 slides to the designated position, the positioning component locks itself mechanically to ensure that the position does not change unexpectedly, thus guaranteeing the accuracy and repeatability of the test.

[0051] Limiting and guiding: Through the cooperation of the limiting groove 211 and the limiting ear 410, the movement path of the impact pin 400 is effectively limited during the test, ensuring stability and safety during the impact process.

[0052] Magnetic control: The magnetic buckle 130 uses magnetic principles to attract and fix the impact pin 400, ensuring the accuracy and safety of the initial positioning. The attraction function of the magnetic buckle 130 effectively prevents the impact pin 400 from falling off during the energy storage process.

[0053] Elastic spring drive: The 311 spring, serving as both energy storage and drive component, provides sufficient stability and reliability. Its elastic design ensures the uniformity and consistency of energy release during each test, avoiding the impact of energy fluctuations during impact.

[0054] The furniture impact resistance testing device provided in this embodiment achieves a highly efficient, adjustable, stable, and reliable impact resistance testing system through the organic combination of an energy storage mechanism, an adjustment mechanism, a positioning and locking device, and a magnetic adsorption function. This device can provide diverse impact modes and precisely control impact energy, thereby more realistically simulating the impact situations that furniture may encounter in actual use, and has broad application prospects.
