Description

Technical Field

[0001] This utility model relates to the field of wooden door technology, specifically a thermal insulation wooden door structure. Background Technology

[0002] Among existing building materials and decorative building materials, doors come in many varieties, including solid wood doors and engineered wood doors. Solid wood doors primarily use natural forests as raw materials, but in the industrialization process, the utilization rate of natural forest logs is only about 20%. Nowadays, people's demand for wooden doors is continuously increasing because they are aesthetically pleasing and practical. However, most engineered wood doors are made by pressing several layers of wood boards and some composite material boards together. Since the pressed wood boards are a solid medium, they do not obstruct sound transmission at all; sound can directly pass through the wood boards, resulting in poor sound insulation and heat preservation, and thus poor practicality. Utility Model Content

[0003] The purpose of this utility model is to provide a heat-insulating wooden door structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A thermally insulated wooden door structure, comprising:

[0006] The wooden frame has connecting holes on both sides, and baffles are installed inside the two connecting holes. Each baffle is screwed with a fixing bolt at both ends. The inner top and inner bottom surfaces of the wooden frame are fixedly connected to fixing plates, and each fixing plate has two rectangular grooves and a threaded groove at both ends. Each fixing plate has two connecting components at both ends. A high-density honeycomb board is slidably connected between the two fixing plates. Two wooden boards are slidably connected inside the wooden frame.

[0007] Two sound-absorbing mechanisms are respectively disposed between the two wooden boards;

[0008] Two buffer mechanisms are respectively disposed between the two sound-absorbing mechanisms.

[0009] Furthermore, sound-absorbing cotton pads are bonded and fixed on both sides of the high-density honeycomb panel, and rock wool boards are bonded and fixed on the opposite sides of the two sound-absorbing cotton pads.

[0010] Furthermore, the connection component includes:

[0011] The L-shaped block is slidably connected to the corresponding rectangular groove. One end of the L-shaped block is provided with a connection notch, and the inner wall of the connection notch is provided with a threaded hole. A compression spring is fixedly connected between one side of the L-shaped block and the inner wall of the corresponding rectangular groove.

[0012] The second fixing bolt has one end screwed into the corresponding threaded hole.

[0013] Furthermore, the sound-absorbing mechanism includes:

[0014] A connecting plate, one side of which is fixedly connected to the connecting plate, and a plurality of placement slots are evenly provided on one side of the connecting plate;

[0015] Four plug-in blocks are fixedly connected to the four corners of the other side of the connecting plate, and one end of each plug-in block has a threaded hole and is slidably plugged into the interior of the corresponding L-shaped block.

[0016] Multiple polyester fiber sound-absorbing panels are respectively bonded and fixed to the inner sidewalls of the multiple placement slots.

[0017] Preferably, the height of the connecting plate is the same as the height of the wooden board, and the width of the connecting plate is the same as the width of the wooden board.

[0018] Furthermore, the buffer mechanism includes a rubber pad, which is bonded and fixed to the middle position of the other side of the connecting plate. The rubber pad has multiple rectangular holes and multiple shock-absorbing components are provided on it.

[0019] Preferably, the shock absorption assembly includes:

[0020] The connector is disposed inside the corresponding rectangular hole;

[0021] A connecting shell is disposed on one side of the connecting seat, and sliding through holes are provided at both ends of the top and bottom of the connecting shell;

[0022] Two push plates are rotatably connected to both ends inside the connecting seat, and a round rod is rotatably connected to one end of the push plate, with both ends of the round rod slidably connected to the corresponding sliding through hole;

[0023] Two movable plates are rotatably connected to the two round rods respectively. Two damping shock absorbers are fixedly connected to one end of each movable plate, and one end of each damping shock absorber is fixedly connected to the inner wall of the connecting shell.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] 1. The sound insulation and heat insulation effect of the insulated wooden door structure is improved by sliding a high-density honeycomb panel between two fixed plates, along with the high-density honeycomb panel, sound-absorbing cotton pad, and polyester fiber sound-absorbing board. The use of rock wool board provides flame retardancy, improving the safety of the insulated wooden door structure after use. By sliding the plug-in block with the corresponding L-shaped block and screwing one end of the fixing bolt two with the corresponding threaded hole one and threaded hole two, the sound-absorbing mechanism can be easily installed and fixed. The compression spring can provide shock absorption and buffering for the wooden frame. By removing the fixing bolt one, the baffle can be easily removed, making it easy to replace the baffle, high-density honeycomb panel, sound-absorbing cotton pad, and rock wool board. By removing the fixing bolt two, the sound-absorbing mechanism can be easily disassembled and replaced, thereby improving the practicality of the insulated wooden door structure.

[0026] 2. By setting two buffer mechanisms between the two sound-absorbing mechanisms, and using rubber pads to absorb the impact force on the wooden frame, when the wooden frame and the sound-absorbing mechanism are moved by a collision, multiple connecting seats will be moved. The movement of the connecting seats will push the push plate and the moving plate to move. The moving plate is limited in the direction of movement by the round rod and the sliding through hole. After moving, the moving plate will squeeze the damping shock absorber. Thus, multiple damping shock absorbers can absorb the impact force on the wooden frame again, thereby reducing the possibility of damage to the buffer mechanism due to collision and improving the service life of the insulated wooden door structure.

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.

[0034] Example 1

[0035] Please see Figure 1-6 In this embodiment of the utility model, a heat-insulating wooden door structure includes: a wooden frame 100, two sound-absorbing mechanisms 200 and two buffer mechanisms 300. Both sides of the wooden frame 100 have connecting holes 101, and each of the two connecting holes 101 has a baffle 120 inside. Both ends of the baffle 120 are screwed with fixing bolts 121. The inner top and bottom surfaces of the wooden frame 100 are fixedly connected to fixing plates 130, and both ends of the fixing plates 130 have two rectangular grooves 131 and threaded grooves 132. Both ends of the fixing plates 130 have two connecting components. A high-density honeycomb board 140 is slidably connected between the two fixing plates 130. Two wooden boards 110 are slidably connected inside the wooden frame 100. The two sound-absorbing mechanisms 200 are respectively disposed between the two wooden boards 110, and the two buffer mechanisms 300 are respectively disposed between the two sound-absorbing mechanisms 200.

[0036] Specifically,

[0037] The use of high-density honeycomb panel 140 and sound-absorbing mechanism 200 improves the heat insulation and sound insulation effect of the insulated wooden door structure. The use of fixing bolts 121 and threaded grooves 132 facilitates the installation and fixing of baffle 120. The two fixed baffles 120 facilitate the limiting and fixing of high-density honeycomb panel 140. The use of buffer mechanism 300 absorbs the impact force on wooden frame 100, reducing the possibility of damage to buffer mechanism 300 due to collision, and improving the practicality of the insulated wooden door structure.

[0038] like Figure 3-4 As shown, in this embodiment, a high-density honeycomb panel 140 is fixedly connected between two fixed plates 130. Sound-absorbing cotton pads 150 are bonded to both sides of the high-density honeycomb panel 140, and rock wool boards 160 are bonded to opposite sides of each of the two sound-absorbing cotton pads 150. The connecting assembly includes an L-shaped block 170 and a second fixing bolt 180. The L-shaped block 170 is slidably connected to the corresponding rectangular groove 131. One end of the L-shaped block 170 has a connecting notch, and the inner wall of the connecting notch has a threaded hole 171. A compression spring 172 is fixedly connected between one side of the L-shaped block 170 and the inner wall of the corresponding rectangular groove 131. One end of the second fixing bolt 180 is screwed into the corresponding threaded hole 171. Sound absorption... The mechanism 200 includes: a connecting plate 210, four plug-in blocks 220 and multiple polyester fiber sound-absorbing panels 230. One side of the connecting plate 210 is fixedly connected to the connecting plate 210. Multiple placement grooves 211 are evenly opened on one side of the connecting plate 210. The four plug-in blocks 220 are respectively fixedly connected to the four corners of the other side of the connecting plate 210. One end of the plug-in block 220 is provided with a threaded hole 221, and one end of the plug-in block 220 is slidably inserted into the interior of the corresponding L-shaped block 170. The multiple polyester fiber sound-absorbing panels 230 are respectively bonded and fixed to the inner sidewalls of the multiple placement grooves 211. The height of the connecting plate 210 is the same as the height of the wooden board 110, and the width of the connecting plate 210 is the same as the width of the wooden board 110.

[0039] In this embodiment, the sound-absorbing cotton pad 150 is used to improve the sound insulation effect of the insulated wooden door structure, and the rock wool board 160 is used for flame retardancy, which improves the safety of the insulated wooden door structure after use. By sliding the plug block 220 into the corresponding L-shaped block 170, and by screwing one end of the fixing bolt 2 180 into the corresponding threaded hole 171 and threaded hole 221, it is easy to install and fix the sound-absorbing mechanism 200. The compression spring 172 can be used to dampen the wooden frame 100. The use of multiple polyester fiber sound-absorbing panels 230 can improve the sound insulation effect of the insulated wooden door structure during use. By removing the fixing bolt 121, it is easy to remove the baffle 120, which makes it easy to replace the baffle 120, high-density honeycomb board 140, sound-absorbing cotton pad 150 and rock wool board 160. By removing the fixing bolt 2 180, it is easy to disassemble and replace the sound-absorbing mechanism 200.

[0040] Example 2

[0041] Based on Embodiment 1, in order to absorb the impact force received by the wooden frame 100, the possibility of damage to the buffer mechanism 300 due to collision is reduced.

[0042] like Figure 5-6 As shown, in this embodiment, the buffer mechanism 300 includes a rubber pad 310, which is bonded and fixed to the middle position of the other side of the connecting plate 210. The rubber pad 310 has multiple rectangular holes 311, and multiple shock-absorbing components are provided on the rubber pad 310. The shock-absorbing components include: a connecting seat 320, a connecting shell 330, two push plates 340, and two moving plates 350. The connecting seat 320 is disposed inside the corresponding rectangular hole 311, and the connecting shell 330 is disposed on one side of the connecting seat 320. The top and bottom ends of the connecting shell 330 are provided with sliding through holes 331. Two push plates 340 are rotatably connected to the two ends inside the connecting seat 320. One end of the push plate 340 is rotatably connected to a round rod 341, and the two ends of the round rod 341 are slidably connected to the corresponding sliding through holes 331. Two moving plates 350 are rotatably connected to the two round rods 341. One end of the moving plate 350 is fixedly connected to two damping shock absorbers 351, and one end of the damping shock absorber 351 is fixedly connected to the inner side wall of the connecting shell 330.

[0043] In practice, the rubber pad 310 absorbs the impact force on the wooden frame 100. When the wooden frame 100 and the sound absorption mechanism 200 move due to a collision, they push multiple connecting seats 320 to move. The movement of the connecting seats 320 pushes the push plate 340 and the moving plate 350 to move. The round rod 341 and the sliding through hole 331 limit the movement direction of the moving plate 350. After moving, the moving plate 350 squeezes the damping shock absorber 351. Thus, the multiple damping shock absorbers 351 can absorb the impact force on the wooden frame 100 again, thereby reducing the possibility of damage to the buffer mechanism 300 due to collision and improving the service life of the insulated wooden door structure.
