Description

Technical Field

[0001] The present application relates to the field of home building materials, and particularly to a paint-free invisible door. Background Art

[0002] In recent years, during house decoration, paint-free invisible doors have been highly favored by people. Compared with traditional doors, the design of invisible doors is more simple and modern. Through a concealed design, the door is integrated with the surrounding environment, making the entire space more beautiful.

[0003] Existing paint-free invisible doors usually adopt invisible door resetters or hydraulic hinges to enable the automatic reset of the invisible door. However, since the invisible door does not adopt the traditional door frame and door lock structure, when the invisible door closes, it may make a relatively large noise when hitting the frame. Summary of the Utility Model

[0004] In order to reduce the noise generated when the invisible door closes and hits the side, the present application provides a paint-free invisible door.

[0005] The paint-free invisible door provided by the present application adopts the following technical solutions:

[0006] A paint-free invisible door includes a door frame profile and a door panel assembly. The door frame profile is installed on the wall. The door frame profile is hinged to the door frame profile through a self-closing hinge. A buffer structure is provided on the door frame profile. The buffer structure includes a buffer rod, a support rod, and a buffer spring. One end of the buffer rod is hinged to the door frame profile. One end of the support rod is hinged to the door frame profile. The other end of the support rod is hinged with a slider. A chute is provided on the buffer rod. The slider is slidably connected in the chute. The buffer spring is installed in the chute and connects the side wall of the chute with the slider.

[0007] By adopting the above technical solutions, the self-closing hinge drives the door panel assembly to reset. When the door panel assembly resets and moves a certain distance, the roller contacts and presses against the door panel assembly. The door panel assembly continues to move. The support rod contacts the door frame profile. The buffer rod rotates relative to the door frame profile. The slider connected to the support rod slides in the chute on the buffer rod and compresses the buffer spring, so as to buffer the closing of the door panel assembly, reduce the force generated when the door panel assembly directly closes and hits the door frame profile, and thus reduce the emitted noise.

[0008] In a specific feasible implementation, the buffer rod further includes a roller, and the roller is rotatably connected to the end of the buffer rod far from the hinge with the door frame profile.

[0009] By adopting the above technical solution, when the support rod buffers the door panel assembly, the roller supports on the door panel assembly and can roll relative to the door panel assembly, which can reduce the friction between the support rod and the door panel assembly and ensure the buffering effect on the door panel assembly.

[0010] In a specific feasible embodiment, the door frame profile includes a first frame and a second frame. A first installation groove is formed on the first frame. One side part of the second frame is clamped in the first installation groove. A first clamping plate is arranged at one end of the first frame away from the second frame. A second clamping plate is arranged at one end of the second frame away from the first frame. A wall body clamping groove is formed on the outer surface of the wall body. The first clamping plate is clamped in the wall body clamping groove, and the second clamping plate is clamped on the surface of the wall body on the side away from the wall body clamping groove.

[0011] By adopting the above technical solution, one end of the second frame is clamped in the first installation groove, the first clamping plate is installed in the clamping groove arranged on the outer surface of the wall body, and the second clamping plate is installed on the part of the wall body on the side away from the clamping groove, so as to fix the door frame profile on the wall body, which is convenient for the disassembly, assembly and maintenance of the door frame profile.

[0012] In a specific feasible embodiment, a sound insulation strip is further included. A second installation groove is formed on the first frame, and the sound insulation strip is installed in the second installation groove.

[0013] By adopting the above technical solution, the sound insulation strip is installed in the second installation groove, and the door panel assembly can abut against the sound insulation strip, thereby improving the sound insulation effect of the invisible door.

[0014] In a specific feasible embodiment, a decorative panel is further included. A clamping block is arranged on the first frame. One end of the decorative panel abuts tightly against the side wall of the wall body clamping groove, and the other end of the decorative panel is clamped on the clamping block.

[0015] By adopting the above technical solution, the decorative panel fills the gap between the wall body and the door frame profile, making the invisible door more concealed and beautiful.

[0016] In a specific feasible embodiment, a first storage groove is formed on the first frame, and both the buffer rod and the support rod are hinged on the inner side wall of the first storage groove.

[0017] By adopting the above technical solution, the buffer rod and the support rod can be stored in the frame storage groove, thereby reducing the gap between the door panel assembly and the door frame profile.

[0018] In a specific feasible implementation, the door panel assembly includes support profiles, frames, an outer door panel, and an inner door panel. There are two support profiles and two frames. The support profiles are snap-connected to the frames. The outer door panel and the inner door panel are installed on both sides of the support profiles and are in contact with the support profiles. The two frames clamp the outer door panel and the inner door panel. The inner door panel is hinged to the doorframe profile. The cavity between the two support profiles is filled with sound insulation filler.

[0019] By adopting the above technical solution, the two support profiles are respectively connected to the two frames. The outer door panel and the inner door panel are clamped and fixed by the two support profiles, thereby forming a complete door panel assembly. While ensuring the structural strength of the door panel assembly, the door panel assembly has a relatively small weight. At the same time, the cavity between the two support profiles is filled with sound insulation filler to ensure the sound insulation effect of the door panel assembly.

[0020] In a specific feasible implementation, it further includes a door handle, and the door handle is installed on the surface of the inner door panel away from the support profile.

[0021] By adopting the above technical solution, the setting of the door handle is beneficial to improving the convenience of opening the hidden door from the inside.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The self-closing page drives the door panel assembly to reset. When the door panel assembly resets and moves a certain distance, the roller contacts and presses against the door panel assembly. The door panel assembly continues to move, the roller rolls relative to the door panel assembly, the buffer rod rotates relative to the doorframe profile, and the slider connected to the support rod slides in the chute of the buffer rod and squeezes the buffer spring to compress it, thereby playing a buffering role in the closing of the door panel assembly, reducing the impact force generated when the door panel assembly directly closes against the doorframe profile, and thus reducing the noise generated.

[0024] 2. When the support rod plays a buffering role for the door panel assembly, the roller supports on the door panel assembly and can roll relative to the door panel assembly, which can reduce the friction between the support rod and the door panel assembly and ensure the buffering effect on the door panel assembly.

[0025] 3. The two support profiles are respectively connected to the two frames. The outer door panel and the inner door panel are clamped and fixed by the two support profiles, thereby forming a complete door panel assembly. While ensuring the structural strength of the door panel assembly, the door panel assembly has a relatively small weight. At the same time, the cavity between the two support profiles is filled with sound insulation filler to ensure the sound insulation effect of the door panel assembly.

One end of the second frame 22 away from the first frame 21 is provided with a second snap plate 221. A wall snap groove 12 is provided on the outer surface of the wall 1. The first snap plate 212 is snap-connected into the wall snap groove 12 of the mounting groove, and the second snap plate 221 is snap-connected to the inner surface of the wall 1, thereby fixing the door frame profile 2 on the wall 1. A second mounting groove 213 is provided on the first frame 21, and the sound insulation strip 23 is installed in the second mounting groove 213.

[0037] In the embodiment of the present application, it further includes a decorative board 24. A snap block 214 is provided on the first frame 21. One end of the decorative board 24 abuts against the inner side wall of the wall snap groove 12, and the other end of the decorative board 24 abuts against the snap block 214, thereby filling the gap between the door frame profile 2 and the wall 1 through the decorative board 24. Then, a layer of latex paint is applied to the outer surfaces of the wall 1 and the decorative board 24, making the invisible door more beautiful.

[0038] The door panel assembly 3 includes support profiles 31, frames 32, outer door panels 33, inner door panels 34 and door handles 36. There are two frames 32 and support profiles 31 respectively. The frames 32 and the support profiles 31 are installed in one-to-one correspondence and fixedly connected. The outer door panels 33 and the inner door panels 34 are both snap-connected to the frames 32 on both sides and abut against the support profiles 31 arranged between them, thereby forming a complete invisible door. A sound insulation filler 35 is filled in the door panel cavity between the two support profiles 31. The sound insulation filler 35 can be made of lightweight sound insulation materials such as foam plastics. The inner door panel 34 is hinged to the first frame 21 on one side through a self-closing hinge 5. The door handle 36 is installed on the inner door panel 34.

The buffer spring 43 is arranged in the chute 411. One end of the buffer spring 43 is connected to the inner side wall of the chute 411, and the other end of the buffer spring 43 is fixedly connected to the slider 44. In the natural state of the buffer rod 41, an included angle of 45° is formed with the first frame 21 under the action of the buffer spring 43. The roller 45 is rotatably connected to the end of the buffer rod 41 far from the end hinged to the door frame profile 2.

[0040] The implementation principle of a paint-free invisible door in the embodiment of the present application is as follows: When the invisible door is opened, the self-closing leaf drives the door panel assembly 3 to reset. When the door panel assembly 3 resets and moves a certain distance, the roller 45 contacts and presses against the door panel assembly 3. As the door panel assembly 3 continues to move, the roller 45 rolls relative to the door panel assembly 3, and the buffer rod 41 rotates relative to the door frame profile 2. The slider 44 connected to the support rod 42 slides in the chute 411 on the buffer rod 41 and squeezes the buffer spring 43 to compress it, thereby playing a buffering role in the closing of the door panel assembly 3, reducing the impact force generated when the door panel assembly 3 directly closes against the door frame profile 2, and thus reducing the noise generated. When the door is opened again, the buffer rod 41 resets again under the action of the buffer spring 43.

[0041] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
