Description

Technical Field

[0001] The present invention relates to the technical field of hinge testing, in particular to a push-back hinge testing device. Background Art

[0002] With the rapid development of smart furniture, push-back hinges (such as W5725) with automatic folding and assembly functions are becoming increasingly popular in furniture, and their mechanical lifespan directly affects the reliability of furniture. The current lifespan test generally adopts the traditional method of manual repeated pushing and pulling and counting, which requires continuous operation until the hinge is damaged. This method has significant drawbacks: 1) Low efficiency, with a single-station test efficiency of only 50-100 times / hour, and a complete test cycle for a single hinge lasting up to 72 hours; 2) High cost, requiring 24-hour manual rotation, and the cost of testing a single hinge reaching ￥15; 3) Insufficient accuracy, with manual force deviation reaching ±15%, and fatigue leading to uneven test force, affecting data consistency; 4) Data recording relies on manual notes, which is prone to errors and lacks quantitative analysis of the failure process. According to furniture standards such as GB / T 3324-2018, hinges must pass more than one million cycle tests, and manual methods can no longer meet the needs of standardized and large-scale production. In summary, traditional testing methods have become a bottleneck restricting the quality control and production efficiency of hinges. It is urgent to develop fully automatic, high-precision mechanized testing equipment to achieve automation, efficiency and standardization of the testing process.

[0031] Example 1.

[0032] See also Figure 1 As shown, the present invention provides a push-back hinge testing device, which includes a fixed frame 1, a driving assembly 2 and a test frame 3. The driving assembly 2 is installed on the fixed frame 1 and drives the connected test frame 3. The test frame 3 is installed on the fixed frame 1 and can swing back and forth relative to the fixed frame 1. The test frame 3 is used to clamp the push-back hinge 4 to be tested. In this embodiment, the push-back hinge 4 to be tested is mainly a W5725 push-back hinge 4. The push-back hinge 4 includes a mounting portion and a movable portion that are hinged to each other. The driving assembly 2 is arranged at one end of the fixed frame 1, and the test frame 3 is arranged on the top of the fixed frame 1 through a hinge. The mounting portion of the push-back hinge 4 to be tested is mounted to the test frame 3 by screws.

[0033] In actual testing, the push-back hinge 4 to be tested is mounted on the test frame 3, and the number of push-pull operations of the drive component 2 is set. When the drive component 2 drives the test frame 3 to swing back and forth relative to the fixed frame 1, the push-back hinge 4 to be tested swings along with the test frame 3. During the swinging process, the movable portion of the push-back hinge 4 swings relative to the mounting portion due to the influence of its own gravity, thereby testing the number of push-pull operations of the push-back hinge 4 to determine its service life. The push-back hinge testing device realizes automated testing by setting the drive component 2 to drive the test frame 3 to swing. It has a simple structure and optimized costs. It replaces the manual push-pull test method, saves labor costs, improves test efficiency, and avoids large errors in test results caused by worker fatigue, thereby improving test accuracy.

[0034] See also Figure 1As shown, the drive assembly 2 includes a motor 21, a push-pull plate 22, a movable plate 23, a first connecting rod 24 and a second connecting rod 25. The motor 21 drives the push-pull plate 22, the push-pull plate 22 is fixedly connected to the movable plate 23, the end of the movable plate 23 close to the motor 21 is rotatably connected to the lower end of the first connecting rod 24, and the end of the movable plate 23 away from the motor 21 is rotatably connected to the lower end of the second connecting rod 25. In this embodiment, the motor 21 is an electric push rod motor 21 equipped with a controller that can set the number of push and pull times. The output end of the motor 21 is fixed to the push-pull plate 22, one end of the push-pull plate 22 is fixedly connected to the middle part of the movable plate 23, and a reinforcing rib is provided at the connection thereof for strengthening and fixing. The first connecting rod 24 and the second connecting rod 25 are cross-arranged. To avoid interference between the first connecting rod 24 and the second connecting rod 25, a pad is provided at the connection between the first connecting rod 24 and the swing plate 31, and a pad is provided at the connection between the second connecting rod 25 and the movable plate 23. During testing, the number of push-pull cycles of the motor 21 can be set to meet furniture standard requirements. If the push-pull hinge 4 remains intact after this number of push-pull cycles, the product meets the standard requirements; otherwise, it fails. When the motor 21 pushes the push-pull plate 22, which drives the movable plate 23 forward, the angle between the first connecting rod 24 and the movable plate 23 increases, while the angle between the second connecting rod 25 and the movable plate 23 decreases, causing the test stand 3 to swing backward. When the motor 21 pulls the push-pull plate 22, which drives the movable plate 23 backward, the angle between the first connecting rod 24 and the movable plate 23 decreases, while the angle between the second connecting rod 25 and the movable plate 23 increases, causing the test stand 3 to swing forward.

[0035] See also Figure 1 As shown, the test frame 3 includes a swing plate 31 and a clamping plate 32. The clamping plate 32 is fixedly connected to the swing plate 31. The end of the swing plate 31 closest to the motor 21 is rotatably connected to the upper end of the second connecting rod 25, and the end of the swing plate 31 away from the motor 21 is rotatably connected to the upper end of the first connecting rod 24. In this embodiment, the clamping plate 32 is perpendicularly connected to the swing plate 31, and a reinforcing rib is provided at the connection between the two to strengthen the fixation. When the motor 21 pushes the movable plate 23 forward, the first connecting rod 24 pushes the swing plate 31 to swing backward so that the angle between the two becomes smaller, and the second connecting rod 25 pulls the swing plate 31 to swing backward so that the angle between the two becomes larger, and the swing plate 31 drives the clamping plate 32 to flip backward, so that the push-back hinge 4 to be tested clamped thereon flips backward, and the movable part of the push-back hinge 4 moves backward and downward relative to the mounting portion under the action of gravity; when the motor 21 pulls the movable plate 23 backward, the first connecting rod 24 pulls the swing plate 31 to swing forward so that the angle between the two becomes larger, and the second connecting rod 25 pushes the swing plate 31 to swing forward so that the angle between the two becomes smaller, and the swing plate 31 drives the clamping plate 32 to flip forward, so that the push-back hinge 4 to be tested clamped thereon flips forward, and the movable part of the push-back hinge 4 moves forward and downward relative to the mounting portion under the action of gravity.

[0036] See also Figure 1 As shown, the fixing frame 1 includes two side panels 11, two bottom panels 12 and a top panel 13. The lower ends of the two side panels 11 are fixedly connected via the two bottom panels 12, and the two ends of the top panel 13 are respectively connected to the upper ends of the two side panels 11. The clamping plate 32 is movably connected to the top panel 13. In this embodiment, the two side panels 11 are both isosceles triangle panels, and the three corners of the side panels 11 are flattened to prevent sharp corners from injuring workers. The two bottom panels 12 are respectively connected to the two bottom corners of the lower ends of the side panels 11, and the top panel 13 is connected to the top corners of the side panels 11. In order to ensure the stable installation of the fixing frame 1 and the test frame 3, the bottom panel 12 and the top panel 13 are installed in parallel. The two side panels 11 are arranged in an isosceles triangle so that the fixing frame 1 is more stable, and the top corners can also avoid interfering with the swinging and flipping of the test frame 3.

[0037] See also Figure 1 As shown, two first hinges 33 are provided at the bottom of the clamping plate 32, and two second hinges 14 are provided on the top plate 13. The two first hinges 33 are hingedly connected to the two second hinges 14 in a one-to-one correspondence. In this embodiment, the two first hinges 33 are respectively fixed to the ends of the clamping plate 32 via screws, and the two second hinges 14 are respectively fixed to the ends of the top plate 13 via screws. The first hinges 33 and the second hinges 14 are both L-shaped structures. The first hinges 33 and the second hinges 14 are connected by hinge bolts, allowing the clamping plate 32 to flip and swing back and forth under the drive of the swing plate 31.

[0038] See also Figure 1 As shown, the apparatus further includes a drive frame 5 secured to one side of the fixed frame 1, with a motor 21 mounted at one end. In this embodiment, the drive frame 5 is a horizontally arranged rectangular frame, with the motor 21 mounted at the rear end of the rectangular frame in the longitudinal direction. The motor 21's driving direction is parallel to the length of the drive frame 5. The presence of the drive frame 5 for mounting the motor 21 prevents one side of the fixed frame 1 from becoming unbalanced and tipping over due to the weight of the drive assembly 2, which could affect normal testing.

[0039] See also Figure 1 As shown, the drive frame 5 includes a slide rail 51, on which a slider 52 is slidably connected, and the slider 52 is fixedly connected to the movable plate 23. In this embodiment, the slide rail 51 is located on the side of the drive frame 5 close to the fixed frame 1. The slide rail 51 is arranged along the length of the drive frame 5, that is, the same as the driving direction of the motor 21. Under the drive of the motor 21, the movable plate 23 can reciprocate along the slide rail 51 via the slider 52, thereby driving the first connecting rod 24 and the second connecting rod 25 to move, ultimately achieving the flipping and swinging of the test frame 3 to test the push-back hinge 4. The arrangement of the slide rail 51 and the slider 52 makes the movement of the movable plate 23 more stable, thereby improving the movement stability of the test frame 3 and making the test results more accurate.

[0040] Please refer to Figure 1 As shown, the fixing bracket 1 further includes two limiting plates 16. The two limiting plates 16 are inclined in an "eight" shape and are respectively located on both sides of the top plate 13. The two ends of the two limiting plates 16 are respectively fixedly connected to the two side plates 11. In this embodiment, the two limiting plates 16 are respectively located obliquely below both sides of the top plate 13, and the included angles between the two limiting plates 16 and the top plate 13 are the same. The inclination angles of the two limiting plates 16 determine the range of the flipping and swinging angles of the clamping plate 32. Therefore, the inclination angles of the limiting plates 16 need to be set according to actual test requirements, so that when the clamping plate 32 flips and swings in place, the movable part of the push-back hinge 4 to be tested can move downward under its own gravity.

[0041] Please refer to Figure 1 As shown, protruding limiting parts 35 are respectively arranged on both sides of the clamping plate 32. The limiting parts 35 are used to abut against the limiting plates 16 to limit the swinging angle of the clamping plate 32. In this embodiment, the clamping plate 32 and the limiting parts 35 are of an integral structure. To increase the limiting stability, the number of the limiting parts 35 on both sides of the clamping plate 32 is two respectively, so that the top view of the clamping plate 32 is in a "艹" - shaped structure. The clamping plate 32 flips and swings under the drive of the swinging plate 31. When the limiting parts 35 abut against the limiting plates 16, the motor 21 stops driving in this direction. The limiting parts 35 and the limiting plates 16 cooperate to limit the flipping and swinging angle of the clamping plate 32, which can prevent the excessive flipping and swinging of the clamping plate 32 caused by the over - driving of the motor 21, affecting the test effect of the push - back hinge 4 to be tested. At the same time, it can prevent the impact force on the motor 21 caused by the movement of the push - back hinge 4 to be tested under its own gravity during the swinging and flipping process of the test stand 3, thus protecting the motor 21.

[0042] Embodiment Two.

[0043] Please refer to Figure 2 As shown, a bearing seat 34 is arranged at the bottom of the clamping plate 32, and a mounting shaft 15 is arranged on the top plate 13. The clamping plate 32 is rotationally mounted on the mounting shaft 15 via the bearing seat 34. In this embodiment, the bearing seat 34 is fixed to the bottom of the clamping plate 32 by screws, and in order to enhance the stability of the clamping plate 32, the number of the bearing seats 34 is two. The two bearing seats 34 are respectively located at both ends of the clamping plate 32. The mounting shaft 15 is fixedly mounted on the top plate 13 via a bracket. The two bearing seats 34 are rotatably sleeved on the mounting shaft 15, realizing that the clamping plate 32 can flip and swing relative to the top plate 13.

[0044] The remaining parts of this embodiment are the same as those of Embodiment One. For the features not explained in this embodiment, the explanations of Embodiment One are adopted and will not be elaborated here.

[0045] In summary, the present invention realizes automated testing by setting a driving component 2 to drive the test frame 3 to swing. It has a simple structure and optimized costs. It replaces the manual push-pull testing method, saves labor costs, improves test efficiency, and avoids large errors in test results caused by worker fatigue, thereby improving the accuracy of the test.
