Description

Technical Field

[0001] This utility model relates to the field of folding doors, and in particular to a heat insulation and noise reduction structure for a thermal break in an anti-pinch folding door. Background Technology

[0002] Folding doors are made up of multiple hinged panels. A typical multi-section folding door includes door panels, a pivot, and a sealing strip. The pivot is located between adjacent door panels and has an outward-extending positioning plate. The positioning plate is located on the inside side. Adjacent door panels fold by rotating through the pivot. The sealing strip is placed in the gap between the door panel and the positioning plate and abuts against the positioning plate.

[0003] However, the existing gap between the door leaf and the positioning plate is small, and the sealing strip in the door gap is also small. Therefore, the cavity in the sealing strip is also small. If a finger is accidentally placed in the door gap and the door leaf is closed at this time, the gap between the door leaf and the positioning plate becomes smaller, and the finger is easily pinched by the door, affecting the user's daily use.

[0004] To address this, Chinese utility model patent CN 220151196 U discloses an anti-pinch folding door with a thermal break. By increasing the gap between the door leaf and the first support pillar, the cavity inside the anti-pinch rubber strip is made larger. When the door leaf is closed, if a finger is accidentally placed in the door gap, both the first and second cavities will be squeezed and deformed, releasing the space inside the first and second cavities to allow the finger to be placed in the door gap, thus preventing the finger from being pinched.

[0005] However, this also brings a new problem: the increased gap between the door leaf and the first support reduces the heat insulation and sound insulation effect of the folding door. Utility Model Content

[0006] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a heat insulation and noise reduction structure for an anti-pinch folding door with a thermal break, which solves the problem that the increased gap between the door leaf and the first support column leads to a decrease in the heat insulation and sound insulation effect of the folding door.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a heat insulation and noise reduction structure for a heat-insulating and anti-pinch folding door with a thermal break, comprising a first frame and a door leaf composed of a second frame and a third frame respectively disposed on both sides of the first frame, wherein one side of the door leaf faces the interior and the other side faces the exterior, characterized in that: the second frame and the third frame are connected to the first frame by hinges;

[0008] The opposite side edges of the second and third frames facing indoors or outdoors are connected to the first frame by pluggable flexible members, and the other sides of the second and third frames are connected to the first frame by abutting parts.

[0009] Multiple heat insulation strips are installed in the chambers on the outdoor-facing side of the first, second, and third frames.

[0010] Furthermore, a movable pulley system is provided within the first frame, and the hinge is connected to the pulley system on the side closest to the first frame.

[0011] Furthermore, the opposing surfaces of the first frame and the second frame or the third frame are respectively provided with a first fastening groove and a second fastening groove, and the two moving ends of the hinge are respectively fastened in the first fastening groove and the second fastening groove by a locking block.

[0012] Furthermore, the first engaging groove includes an outer groove and an inner groove that are connected to each other. The locking block is located in the outer groove, and the pulley assembly is located in the inner groove. The locking block and the pulley assembly are interlocked.

[0013] Furthermore, the flexible component includes a first anti-pinch rubber block and a second anti-pinch rubber block. The first anti-pinch rubber block is fastened to the first frame, and the second anti-pinch rubber block is fastened to the second frame and the third frame, and the first anti-pinch rubber block and the second anti-pinch rubber block overlap.

[0014] Furthermore, the overlapping surfaces of the first and second anti-pinch rubber blocks are arc-shaped.

[0015] Furthermore, the second anti-pinch rubber block has an extension on the side near the inner cavity of the second and third frames.

[0016] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, when installing the folding door, the second frame is installed on the left side of the first frame and the third frame is installed on the right side of the first frame, with the first frame as the base point. Both the second and third frames are connected to the first frame through hinges. Since the hinges are located in the inner cavity of the door leaf formed by the combination of the first, second, and third frames, the two sides of the connection between the first, second, and third frames can be sealed by flexible parts and abutment parts to enhance the heat insulation and noise reduction effect of the folding door. To further enhance the noise reduction effect, heat insulation strips are added to the inner cavities of the first, second, and third frames facing the outside to improve the noise reduction and heat insulation effect.

[0017] To more clearly illustrate the structural features and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0021] Door leaf 1, hinge 2, locking block 21, flexible component 3, first anti-pinch rubber block 31, second anti-pinch rubber block 32, extension part 321, contact part 4, heat insulation strip a, pulley block 5;

[0022] First frame 10, second frame 20, third frame 30;

[0023] First fastening groove 61, outer groove 611, inner groove 612, second fastening groove 62. Detailed Implementation

[0024] Please refer to Figure 1-2 As shown, it illustrates the specific structure of a preferred first embodiment of the present invention, which is a heat insulation and noise reduction structure for a folding door with a thermal break to prevent hand pinching. It includes a first frame 10 and a door leaf 1 composed of a second frame 20 and a third frame 30 respectively disposed on both sides of the first frame 10. The door leaf 1 faces the interior and the exterior. The feature is that the second frame 20 and the third frame 30 are connected to the first frame 10 by hinges 2.

[0025] The opposite side edges of the second frame 20 and the third frame 30 facing indoors or outdoors are connected to the first frame 10 by pluggable flexible members 3, and the other side of the second frame 20 and the third frame 30 are connected to the first frame 10 by abutting parts 4.

[0026] Multiple heat-insulating strips a are provided in the chambers of the first frame 10, the second frame 20, and the third frame 30 facing the outside. When installing the folding door, the second frame 20 is installed on the left side of the first frame 10, and the third frame 30 is installed on the right side of the first frame 10, with the first frame 10 as the base point. Both the second frame 20 and the third frame 30 are connected to the first frame 10 by hinges 2. Since the hinges 2 are located in the inner cavity of the door leaf 1 formed by the combination of the first frame 10, the second frame 20, and the third frame 30, the two sides of the connection between the first frame 10, the second frame 20, and the third frame 30 can be sealed by the flexible parts 3 and the abutment parts 4 to enhance the heat insulation and noise reduction effect of the folding door. To further enhance the noise reduction effect, heat-insulating strips a are added to the inner cavities of the first frame 10, the second frame 20, and the third frame 30 facing the outside to improve the noise reduction and heat insulation effect.

[0027] For example, a movable pulley assembly 5 is provided within the first frame 10, and the hinge 2 is connected to the pulley assembly 5 on the side closest to the first frame 10. Because of the pulley assembly 5, installers can adjust the position of the hinge 2 within the door leaf 1 according to actual usage needs to meet different installation environments.

[0028] For example, the opposing surfaces of the first frame 10 and the second frame 20 or the third frame 30 are respectively provided with a first engaging groove 61 and a second engaging groove 62. The two moving ends of the hinge 2 are respectively engaged in the first engaging groove 61 and the second engaging groove 62 by means of locking blocks 21. By the insertion of the two locking blocks 21 into the first engaging groove 61 and the second engaging groove 62 respectively, the hinge 2 is effectively limited, so that the stability of the hinge 2 is not affected when the user pulls the door leaf 1 to open or close.

[0029] For example, the first engaging groove 61 includes an outer groove 611 and an inner groove 612 that are connected. A locking block 21 is disposed in the outer groove 611, and a pulley assembly 5 is disposed in the inner groove 612, with the locking block 21 and the pulley assembly 5 interlocked. The connection between the outer groove 611 and the locking block 21 prevents the hinge 2 from separating from the first engaging groove 61 due to lateral tension. At the same time, the connection between the outer groove 611 and the inner groove 612 allows the pulley assembly 5 in the inner groove 612 to interlock with the locking block 21. When the pulley assembly 5 is installed on the first frame 10 by screws, the locking block 21 cannot move laterally, preventing it from separating from the pulley assembly 5. The locking block 21 can also drive the second frame 20 and the third frame 30 to operate normally with the first frame 10 without additional fixing.

[0030] For example, the flexible component 3 includes a first anti-pinch rubber block 31 and a second anti-pinch rubber block 32. The first anti-pinch rubber block 31 is fastened to the first frame 10, and the second anti-pinch rubber block 32 is fastened to the second frame 20 and the third frame 30, with the first and second anti-pinch rubber blocks 31 and 32 overlapping each other. Because the flexible component 3 is divided into the first anti-pinch rubber block 31 and the second anti-pinch rubber block 32, when the second frame 20 or the third frame 30 is bent by the hinge 2, the user's hand is placed between the first and second anti-pinch rubber blocks 31 and 32. The flexibility of the rubber blocks 32 can also reduce the injury to the hand and avoid hand injury caused by pinching. In addition, the sealing effect of the first and second anti-pinch rubber blocks 31 and 32 can further enhance the heat insulation and sound insulation effect of this folding door.

[0031] Specifically, the overlapping surfaces of the first anti-pinch block 31 and the second anti-pinch block 32 are arc-shaped. This arc-shaped design of the overlapping surfaces of the first anti-pinch block 31 and the second anti-pinch block 32 enhances the connection between them and improves their sealing performance.

[0032] The second anti-pinch rubber block 32 has an extension portion 321 on one side near the inner cavity of the second frame 20 and the third frame 30.

[0033] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
