Description

Technical Field

[0001] This utility model relates to the field of solid wood composite door testing technology, specifically a solid wood composite door impact resistance testing device. Background Technology

[0002] With the rapid development of the building decoration industry, solid wood composite doors, combining the natural texture of solid wood with the stability of composite panels, are increasingly widely used in residential and commercial spaces. As a key component for separating indoor and outdoor spaces, solid wood composite doors not only need to meet aesthetic requirements, but their impact resistance is also a core indicator for ensuring safety and lifespan. In daily use, doors may face impacts from furniture collisions and accidental bumps. Insufficient impact resistance can easily lead to problems such as door panel cracking, deformation, and hardware detachment. In severe cases, it can even cause a loss of structural integrity, threatening the safety of residents. Therefore, precise testing of the impact resistance of solid wood composite doors before they leave the factory has become a necessary part of the industry's quality control.

[0003] Existing experiments mostly use impact blocks of fixed weight and shape to fall freely from a single height, which can only simulate "vertical point impact". The impacts that a door actually experiences are diverse, and different impact scenarios require different test heads. For example, "oblique impact" when moving furniture requires a conical test head, "surface contact impact" when people collide requires a flat test head, and "localized concentrated impact" in the door lock area requires a cylindrical test head. However, traditional devices lack convenient test head disassembly and assembly mechanisms. Replacing a test head requires fixing with multiple sets of bolts or disassembling with special tools, which is a complicated operation process and takes several minutes of time and effort for each replacement. At the same time, the impact points of existing experimental devices are mostly fixed, but in actual use, different parts of the door may be impacted. The fixed impact point testing method cannot conduct impact resistance tests on different parts of solid wood composite doors, resulting in test results that cannot fully reflect the overall impact resistance performance of the door.

[0028] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0029] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0030] Example 1

[0031] As attached Figures 1 to 8 The impact resistance testing device for solid wood composite doors shown includes: a base 1, with two symmetrically distributed linear guide rails a11 fixedly mounted on the top of the base 1, a gantry frame 12 fixedly mounted between the two linear guide rails a11, a test platform 13 fixedly mounted on the top of the base 1, a mounting seat 14 above the test platform 13, and a test head 15 at the bottom of the mounting seat 14; a disassembly and assembly mechanism, located on the mounting seat 14, for easy replacement of different types of test heads 15; and a testing mechanism, located on the gantry frame 12, used for testing the solid wood composite door.

[0032] In the process of testing solid wood composite doors, the solid wood composite door is placed on the test platform 13. The gantry frame 12 is moved to the testing position of the solid wood composite door by starting the linear guide rail a11. The required type of test head 15 is installed according to the testing requirements. The set disassembly and assembly mechanism can easily replace the test head 15, improving the replacement efficiency of the test head 15. Then, the test mechanism lifts the test head 15 to the required height and releases it, so that the test head 15 falls to conduct an impact test on the solid wood composite door, thereby testing the impact resistance performance of the solid wood composite door.

[0033] In a preferred embodiment, two fixing plates 4 are fixedly connected to the top of the test bench 13. Hydraulic push rods 41 are fixedly installed on opposite sides of the two fixing plates 4, and placement plates 42 are provided on opposite sides of the two fixing plates 4. The output end of the hydraulic push rods 41 is connected to the placement plate 42 on the adjacent side.

[0034] Furthermore, when testing the solid wood composite door, the solid wood composite door is placed on two placement plates 42. By activating the hydraulic push rods 41 on both sides, the output ends of the hydraulic push rods 41 are pushed out simultaneously, pushing the two placement plates 42 to move relative to each other and clamp and fix the solid wood composite door. The output ends of the hydraulic push rods 41 on both sides are controlled to retract, causing the two placement plates 42 to loosen their fixation on the solid wood composite door.

[0035] In a preferred embodiment, a protective fence 5 is fixedly installed on the top of the base 1. The protective fence 5 is provided with two protective doors 51, and a bolt 52 is provided between the two protective doors 51.

[0036] Furthermore, when testing the solid wood composite door, the bolt 52 is opened to release the fixation of the two protective doors 51. Then, the two protective doors 51 are opened, the solid wood composite door is placed on the test table 13, and then the two protective doors 51 are closed. The bolt 52 is then closed to fix the two protective doors 51. The two protective doors 51 and the protective fence 5 prevent wood chips from flying when the solid wood composite door is damaged during testing, so as to prevent the flying wood chips from injuring the test personnel.

[0037] Example 2

[0038] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 8 As shown below, see details:

[0039] The disassembly and assembly mechanism includes: mounting slot 2, mounting head 21, moving slot 22, screw block 23, connecting plate 24, and connecting slot 25. The mounting base 14 has a mounting slot 2 at its bottom. The top of the test head 15 is fixedly connected to the mounting head 21 that is used in conjunction with the mounting slot 2. The top of the mounting slot 2 has a moving slot 22. The moving slot 22 has two symmetrically arranged screw blocks 23 inside. The bottom of each screw block 23 is fixedly connected to a connecting plate 24 with an L-shaped structure. The top of the mounting head 21 has a connecting slot 25 with an inverted T-shaped structure. The connecting slot 25 has a bidirectional threaded rod 26 inside. The two screw blocks 23 are respectively threaded to two sections of opposite threads on the outside of the bidirectional threaded rod 26. An adjusting head 27 is fixedly installed on one side of the mounting base 14. The drive shaft at one end of the adjusting head 27 is connected to one end of the bidirectional threaded rod 26. A rotary damper 28 is fixedly installed on the other side of the mounting base 14. The output end of the rotary damper 28 is connected to the other end of the bidirectional threaded rod 26.

[0040] When replacing the test head 15, a wrench is inserted into the adjusting head 27 and rotated. This rotates the bidirectional threaded screw 26 of the adjusting head 27, which engages with two screw blocks 23. Because the two threads are opposite, the two screw blocks 23 move relative to each other. The screw blocks 23 then move the two connecting plates 24 relative to each other, causing them to close and release the fixing of the mounting head 21. Subsequently, the adjusting head 27 closes, and under the influence of gravity, the mounting head 21 and the test head 15 fall, causing the mounting head 21 to move out of the mounting slot 2, thus removing the test head 15. During installation, the mounting head 21 at the top of the test head 15 is inserted into the mounting groove 2, and the two connecting plates 24 are inserted into the mounting groove 2. Then, by turning the adjusting head 27 with a wrench, the bidirectional threaded screw 26 is rotated in the opposite direction, causing the two screw blocks 23 to move in opposite directions. This causes the bottom ends of the two connecting plates 24 to be respectively inserted into the connecting grooves 25, thereby connecting and fixing the mounting head 21. The rotation damper 28 can provide rotational damping force, thereby preventing the bidirectional threaded screw 26 from rotating arbitrarily, thus limiting the bidirectional threaded screw 26 and preventing it from rotating due to impact.

[0041] Example 3

[0042] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 8 As shown below, see details:

[0043] The testing mechanism includes: guide rods 3, guide plates 31, linear guide rails b32, and electric winches 33. Guide rods 3 are provided on opposite sides of the gantry frame 12. The top and bottom ends of the guide rods 3 are connected to the top and bottom of the gantry frame 12, respectively. A guide plate 31 is slidably connected between the two guide rods 3. A linear guide rail b32 is fixedly installed at the bottom of the guide plate 31. A mounting base 14 is fixedly installed at the bottom of the moving platform of the linear guide rail b32. An electric winch 33 is fixedly installed at the top inside the gantry frame 12. The cable of the electric winch 33 is connected to the top of the guide plate 31. Limit plates 34 are fixedly installed on the inner walls on opposite sides of the gantry frame 12, and limit buttons 35 are fixedly installed at the bottom of each limit plate 34.

[0044] During the testing of the solid wood composite door, the electric winch 33 is activated to wind up the cable, causing the guide plate 31 to move upwards along the outside of the two guide rods 3 until the guide plate 31 touches the limit button 35, causing the electric winch 33 to stop working. Alternatively, the height of the guide plate 31 can be controlled by manually turning off the electric winch 33. After the guide plate 31 rises to the specified height, the rotation damper of the electric winch 33 is activated. Under the action of gravity, the mounting base 14 and the test head 15 cause the guide plate 31 to move downwards along the outside of the two guide rods 3, causing the test head 15 to fall and impact the solid wood composite door for testing. The impact resistance of the solid wood composite door is improved by adjusting the impact position through the linear guide rail b32 to move the mounting base 14 laterally. A buffer rubber pad can be set between the mounting base 14 and the moving platform of the linear guide rail b32. In conjunction with adjusting the vertical position of the gantry frame 12, the impact position of the solid wood composite door can be adjusted. The top of the moving platform of the linear guide rail b32 contacts the bottom of the guide plate 31. When the test head 15 falls and impacts the solid wood composite door, the reaction force generated acts on the guide plate 31, which will not impact the linear guide rail b32, and can also control the movement of the mounting base 14.

[0045] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.

[0046] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
