Description

Technical Field

[0001] The utility model relates to the field of door and window profiles, in particular to a thermal insulation system indoor door. Background Art

[0002] Broken bridge aluminum doors and windows usually use thermal insulation broken bridge aluminum profiles, which have the functions of energy saving, sound insulation, noise prevention, dust prevention, waterproofing, etc. The thermal conductivity coefficient K value of broken bridge aluminum doors and windows is usually below 3W / ㎡·K, which reduces the heat loss by half compared with ordinary doors and windows, and can effectively reduce heating costs.

[0003] However, the existing thermally insulated aluminum doors and windows usually only stack thermally insulating and soundproofing materials to provide thermally insulating and soundproofing effects at structural positions such as door leaves and door frames. However, the actual effect is mainly at the thermally insulating and soundproofing materials. At the junction of the door leaf profile and the door frame profile, there must be a certain gap because the door leaf needs to open and close, making it difficult to ensure the thermally insulating and soundproofing effects at the junction of the door leaf profile and the door frame profile, which in turn leads to poor thermally insulating and soundproofing effects of the overall thermally insulated aluminum doors and windows.

[0009] Furthermore, a shock-absorbing strip is provided on one side of the second corner structure, and the shock-absorbing strip is wrapped around the side of the second sound insulation seal away from the door leaf profile.

[0010] Furthermore, a dust strip is telescopically provided at the bottom of the door leaf profile so that when the door leaf is closed, the dust strip falls down and rests against the ground.

[0011] Furthermore, the door leaf has a keel inside, and the outside of the keel is wrapped with an insulation board.

[0015] At the same time, since both the first corner structure and the second corner structure have grooves, the first sound insulation seal and the second sound insulation seal can be arranged in the grooves, thereby improving the stability of the installation of the sound insulation seal and avoiding the sound insulation seal from being too abrupt.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

Therefore, the above terms should not be understood as limiting the present invention.

[0022] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0023] like Figure 1-3 The utility model provides a thermal insulation system indoor door, including a door leaf profile 2 arranged on the side of a door leaf 1 and a door frame profile 4 arranged on the side of a door frame 3, wherein the door leaf profile 2 and the door frame profile 4 correspond to each other when the door leaf 1 is closed, and the door leaf profile 2 has a first corner structure 5 on the side close to the door frame profile 4, and the door frame profile 4 has a second corner structure 6 matching the first corner structure 5, and both the first corner structure 5 and the second corner structure 6 have grooves, and the first corner structure 5 has a first sound insulation seal 7 built in, and the second corner structure 6 has a second sound insulation seal 8 built in, so that when the door leaf 1 is closed, the first sound insulation seal 7 and the second sound insulation seal 8 are fitted together.

[0024] When the door leaf is closed, the door leaf profile and the door frame profile correspond to each other. At this time, the first corner structure and the second corner structure are overlapped, so that the door leaf is stably closed on the door frame. At the same time, due to the setting of the first sound insulation seal and the second sound insulation seal, the junction between the door leaf and the door frame can be insulated and soundproofed by the first sound insulation seal and the second sound insulation seal, thereby improving the partition effect of the gap at the junction of the door leaf and the door frame to avoid the gap affecting the overall heat insulation and sound insulation effects of the door leaf.

[0025] At the same time, since both the first corner structure and the second corner structure have grooves, the first sound insulation seal and the second sound insulation seal can be arranged in the grooves, thereby improving the stability of the installation of the sound insulation seal and avoiding the sound insulation seal from being too abrupt.

[0026] In one embodiment of the present solution, both the first sound insulation seal and the second sound insulation seal are made of automotive-grade EPDM foamed sound insulation sealing strips.

[0027] Preferably, the door leaf profile 2 has a protrusion 9 on one side of the first corner structure 5, and the door frame profile 4 has a recessed portion 10 on one side of the second corner structure 6, and the protrusion 9 and the recessed portion 10 are arranged correspondingly, and the protrusion 9 and the recessed portion 10 both have grooves, and the protrusion 9 has a third sound insulation seal 11 built in, and the recessed portion 10 has a fourth sound insulation seal 12 built in, so that when the door leaf 1 is closed, the third sound insulation seal 11 corresponds to the fourth sound insulation seal 12.

[0028] Specifically, one side of the first corner structure is formed by the protrusion, and one side of the second corner structure is formed by the recessed portion, so that when the first corner structure corresponds to the second corner structure, the protrusion and the recessed portion are also in a corresponding state, so that the third sound insulation seal and the fourth sound insulation seal form a second layer of heat insulation and sound insulation structure at the junction of the door leaf and the door frame, so as to improve the sound insulation and heat insulation effect of the door leaf.

[0029] In one embodiment of the present solution, the third sound insulation seal and the fourth sound insulation seal are both made of automotive-grade EPDM foamed sound insulation sealing strips.

[0030] Preferably, a door leaf heat insulation member 13 is provided on a side of the first corner structure 5 away from the door frame profile 4 , and a door frame heat insulation member 14 is provided on a side of the second corner structure 6 away from the door leaf profile 2 .

[0031] Specifically, the door leaf insulation component and the door frame insulation component are used to insulate and seal both sides of the junction between the door leaf and the door frame, thereby improving the insulation effect at that location and avoiding the situation where the insulation effect at the profile position is deteriorated due to the hollow structure of the profile.

[0032] In one embodiment of the present solution, both the door leaf insulation component and the door frame insulation component adopt high temperature resistant insulation strips.

[0033] Preferably, the door leaf profile 2 is provided with a heat-insulating cavity 15 , which is located on a side of the protrusion 9 away from the door frame profile 4 , and a heat-insulating component 16 is built into the heat-insulating cavity 15 .

[0034] Specifically, since the door frame profile is arranged on the side of the door frame and the door leaf profile is arranged on the side of the door leaf, and the door leaf is compared with the door frame because the other side of the door frame is attached to the wall, the door frame and the door frame profile itself have better sound insulation and heat insulation effects. In order to simultaneously improve the heat insulation and sound insulation effects of the door leaf and the door leaf profile, an insulation cavity is added to the door leaf profile, and the heat insulation effect of the door leaf profile is improved by the insulation parts, so as to ensure that the door leaf and door frame have good heat insulation and sound insulation effects.

[0035] In one embodiment of this solution, the thermal insulation component is made of foamed thermal insulation material.

[0036] Preferably, a shock absorbing strip 17 is provided on one side of the second corner structure 6 , and the shock absorbing strip 17 is wrapped around the side of the second sound insulation seal 8 away from the door leaf profile 2 .

[0037] Specifically, when the door leaf is closed, it will generate certain vibrations on the door frame. At this time, the vibration can be reduced by the shock-absorbing strip to avoid problems such as structural damage and loud closing noise of the door leaf.

[0038] In one embodiment of the present solution, the shock absorbing strip may be a shock absorbing leather strip.

[0039] Preferably, a dust strip 18 is telescopically provided at the bottom of the door leaf profile 2, so that when the door leaf 1 is closed, the dust strip 18 falls down and rests against the ground.

[0040] Specifically, when the door leaf is closed, the falling dustproof strip provides sound insulation and heat insulation between the bottom and the bottom surface of the door leaf, thereby ensuring the overall sound insulation and heat insulation effect of the door leaf.

[0041] In one embodiment of the present scheme, a spring is connected between the dust strip and the door leaf to ensure that the dust strip can retract to the inner side of the door leaf when the door leaf is opened; at the same time, a pressing block is horizontally arranged at the bottom of the door leaf, one end of the pressing block protrudes at the junction of the door leaf profile and the door frame profile, and a spring is connected between the pressing block and the door leaf, and the pressing block and the dust strip are connected by an inclined surface or an inclined wedge, so that when the door leaf is closed, the protruding end of the pressing block is pushed by the door frame profile to make the pressing block shrink toward the inner side of the door leaf. At this time, due to the oblique wedge connection between the pressing block and the dust strip, the horizontally shrinking pressing block drives the dust strip to fall in the vertical direction, so that the dust strip can play a sound insulation and heat insulation effect. After the door leaf is opened, the pressing block and the dust strip are reset by the spring respectively, so that the dust strip shrinks and the end of the pressing block protrudes.

[0042] Preferably, the door leaf 1 has a keel 19 inside, and the outside of the keel 19 is wrapped with an insulation board 20.

[0043] Specifically, the heat insulation effect of the door leaf body is improved by the heat insulation board, and the structural strength of the door leaf itself is increased by the keel structure to avoid deformation of heat insulation and sound insulation elements such as the heat insulation board.

[0044] In one embodiment of the present solution, the insulation board may be a 44 mm insulation extruded board, and the keel may be an aluminum keel.

[0045] Preferably, the door leaf 1 has decorative panels 21 on both sides of its exterior, and a heat-insulating and sound-proofing panel 22 is provided between the decorative panel 21 and the heat-insulating panel 20 .

[0046] Specifically, the heat insulation and sound insulation effects of the door leaf itself are further increased by using the heat insulation and sound insulation panels, while the appearance of the door leaf is improved by using the decorative panels to prevent the heat insulation and sound insulation components from leaking out.

[0047] In one embodiment of the present solution, the decorative panel may be a 5mm wood veneer, and the thermal insulation and sound insulation panel may be a 6mmA1 grade flame retardant thermal insulation and sound insulation panel.

[0048] Preferably, a first arc-shaped flap 23 is arranged on the outer side of the first sound insulation seal 7, and a second arc-shaped flap 24 is arranged on the outer side of the second sound insulation seal 8, so that when the door leaf 1 is closed, the first arc-shaped flap 23 overlaps with the second arc-shaped flap 24.

[0049] Specifically, when the door leaf is closed, the first arc-shaped lap joint is overlapped with the second arc-shaped lap joint, so that the overlap between the first sound insulation seal and the second sound insulation seal is tighter, so as to avoid the transmission of sound, heat, etc. from the junction of the door leaf and the door frame, so that the heat insulation and sound insulation effects at this location are better.

[0050] The arc-shaped structure of the arc-shaped spandrels enables the arc-shaped spandrels to deform to a certain extent when overlapping, so as to ensure the tightness of the overlap between adjacent arc-shaped spandrels.

[0051] The present utility model is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all those having the same or similar technical solutions as the present application fall within the protection scope of the present utility model.
