This utility model relates to the field of swing door technology and discloses a novel thermal break swing door, including a thermal break door frame. The left side of the thermal break door frame is connected to a thermal break side frame via multiple hinge mechanisms. In this novel thermal break swing door, when opening, the hinge mechanism drives piston two to slide upwards in the inner cylinder. Hydraulic oil flows back through the upper oil drain groove. When the door is opened to 75°, piston two blocks the upper oil drain groove, increasing resistance and slowing the opening speed to prevent impact with the wall. After opening to 85°, piston two completely blocks the upper oil drain groove. Continuing to push the door compresses the locking component disc spring, opening the connecting hole. Force is stopped at any angle within 170°, and the disc spring returns to its original position, locking the door. When closing, piston two moves downwards, causing hydraulic oil to push the locking component to open. When closed below 75°, the return spring releases potential energy, causing the door to close automatically. When closed to 10°, piston two blocks the lower oil drain groove, increasing resistance and slowing the closing speed to avoid impact with the thermal break door frame, thus improving usability.

Description

Technical Field

[0001] This utility model relates to the field of swing door technology, and in particular to a novel thermal break swing door. Background Technology

[0002] Thermally broken casement doors are window and door products that combine thermal break technology with the structure of casement doors. The thermal break technology uses thermal break strips within the profiles to divide the door frame and door leaf into inner and outer sections, effectively blocking heat transfer and improving the thermal insulation performance of the doors and windows. Casement doors, on the other hand, use hinges and other connectors to allow the door leaf to rotate around the side of the door frame to open or close. They feature a large opening area, good ventilation, and strong sealing, and are widely used in residential and commercial buildings.

[0003] When using thermally broken swing doors, we found that existing swing doors lack an effective buffer mechanism when opening and closing. When the opening angle is large, the door leaf is prone to hitting the wall due to inertia, resulting in damage to the door leaf and the wall; when closing, it may violently hit the door frame, generating noise and affecting the service life of the door and window. Utility Model Content

The hinge mechanism includes an upper hinge, a hydraulic assembly, a reset assembly, and a lower hinge. The outer periphery of the hydraulic assembly is fixedly connected to the inside of the upper hinge. The lower part of the hydraulic assembly is disposed above the reset assembly. The outer periphery of the reset assembly is disposed inside the lower hinge. An annular gasket is disposed between the upper and lower hinges. The lower hinge is connected to the thermal break door frame by screws, and the upper hinge is connected to the thermal break door frame by screws.

[0006] Preferably, the reset assembly includes a spline column, a spring, a frustum, a slider, a groove, and a connecting sleeve. The upper end of the spline column is connected to the hydraulic assembly, and the lower end of the spline column is fixedly connected to the middle of the frustum. One end of the slider is fixedly connected to the outer periphery of the frustum, and the outer periphery of the slider is slidably connected to the inside of the groove. The groove is located in the middle of the connecting sleeve, and the outer periphery of the frustum is slidably connected to the inside of the connecting sleeve. The outer periphery of the connecting sleeve is fixedly connected to the inside of the lower hinge. The spring is sleeved on the outer periphery of the spline column and is disposed between the frustum and the hydraulic assembly.

[0007] Preferably, the hydraulic assembly includes an outer cylinder, an inner cylinder, multiple drain holes, an upper drain groove, a lower drain groove, a locking assembly, a second piston, a connecting column, and a key sleeve. The upper end of the connecting column is fixedly connected to the middle of the second piston, and the outer periphery of the second piston is slidably connected to the inside of the inner cylinder.

The lower end of the connecting column is fixedly connected to the upper end of a spline column, and the outer periphery of the spline column is slidably connected to the inside of the key sleeve. The upper end of the key sleeve is fixedly connected to the lower end of the inner cylinder. The middle of the upper and lower sides of the outer cylinder is fixedly connected to the outer periphery of the inner cylinder. Multiple drain holes are opened in the upper part of the inner cylinder. The upper drain groove is opened in the middle of the inner cylinder. The lower drain groove is opened in the lower part of the inner cylinder. The locking assembly is installed on the upper side inside the inner cylinder and is located between the drain holes and the upper drain groove. The outer cylinder and the inner cylinder are filled with hydraulic oil.

[0008] Preferably, the locking assembly includes an isolation plate, a connecting hole, a piston, multiple connecting rods, two movable plates, and two disc springs. The outer periphery of the isolation plate is fixedly connected to the inner wall of the upper part of the inner cylinder. The connecting hole is opened in the middle of the isolation plate. The outer periphery of the piston is slidably connected to the inside of the connecting hole.

When the door is closed to below 75°, the return spring releases potential energy, causing the door to close automatically. When the door is closed to 10°, piston two blocks the lower oil drain groove, increasing resistance and slowing down the closing speed to avoid impact with the thermal break door frame, thus improving the flexibility of use.

The reset assembly 203 includes a spline column 2031, a spring 2032, a frustum 2033, and a slider 2. 034, Slide groove 2035 and connecting sleeve 2036, the upper end of spline column 2031 is connected to hydraulic component 202, the lower end of spline column 2031 is fixedly connected to the middle of frustum 2033, one end of slider 2034 is fixedly connected to the outer periphery of frustum 2033, the outer periphery of slider 2034 is slidably connected to the inside of slide groove 2035, slide groove 2035 is opened in the middle of connecting sleeve 2036, the outer periphery of frustum 2033 is slidably connected to the inside of connecting sleeve 2036, the outer periphery of connecting sleeve 2036 is fixedly connected to the inside of lower hinge 204, spring 2032 is sleeved on the outer periphery of spline column 2031, and spring 2032 is set on frustum 2033. Between the hydraulic assembly 202 and the hydraulic component 202, the hydraulic assembly 202 includes an outer cylinder 2021, an inner cylinder 2022, multiple oil drain holes 2023, an upper oil drain groove 2024, a lower oil drain groove 2025, a locking assembly 2026, a second piston 2027, a connecting column 2028, and a key sleeve 2029. The upper end of the connecting column 2028 is fixedly connected to the middle of the second piston 2027, and the outer periphery of the second piston 2027 is slidably connected to the inside of the inner cylinder 2022. The lower part of the connecting column 2028 passes through and is slidably connected to the lower middle of the inner cylinder 2022. The lower end of the connecting column 2028 is fixedly connected to the upper end of the spline column 2031, and the outer periphery of the spline column 2031 is... The key sleeve 2029 is slidably connected inside the key sleeve 2029. The upper end of the key sleeve 2029 is fixedly connected to the lower end of the inner cylinder 2022. The middle of the upper and lower sides of the outer cylinder 2021 is fixedly connected to the outer periphery of the inner cylinder 2022. Multiple oil drain holes 2023 are opened on the upper part of the inner cylinder 2022. The upper oil drain groove 2024 is opened in the middle of the inner cylinder 2022. The lower oil drain groove 2025 is opened in the lower part of the inner cylinder 2022. The locking component 2026 is installed on the upper side inside the inner cylinder 2022. The locking component 2026 is located between the oil drain holes 2023 and the upper oil drain groove 2024. The outer cylinder 2021 and the inner cylinder 2022 are filled with hydraulic oil.

[0017] Specifically, the door can automatically close when it is opened from 0° to 85°, and can be locked at any angle from 85° to 170°. It also has a buffering effect from 0° to 10° and from 75° to 85°.

[0018] In this embodiment, the locking assembly 2026 includes an isolation plate 20261, a connecting hole 20262, a piston 20263, multiple connecting rods 20264, two movable plates 20265, and two disc springs 20266. The outer periphery of the isolation plate 20261 is fixedly connected to the upper inner wall of the inner cylinder 2022. The connecting hole 20262 is opened in the middle of the isolation plate 20261. The outer periphery of the piston 20263 is slidably connected to the inside of the connecting hole 20262. One end of the connecting rod 20264 is fixedly connected to the upper and lower sides of the piston 20263, and the other end of the connecting rod 20264 is fixedly connected to the opposite side of the two movable plates 20265. The disc spring 20266 is set between the isolation plate 20261 and the movable plate 20265, and the disc spring 20266 is sleeved on the outer periphery of the connecting rod 20264. An electrochromic film is set in the middle of the double-layer glass 5. The electrochromic film is connected to the external control terminal through a wire. A handle 4 is set at the front right side of the broken bridge frame 3.

[0019] Specifically, the part of the wire passing through the broken bridge frame (3) is sealed by means of foam or sealant. When the piston 2027 does not seal the upper oil drain groove 2024 or the lower oil drain groove 2025, the upper and lower disc springs 20266 will press the piston 1 20263 into the middle of the connecting hole 20262 through the movable plate 20265 and the connecting rod 20264, so that the locking assembly 2026 remains in a normally closed state. At this time, the elastic force of the spring 2032 is not enough to push the hydraulic oil to open the piston 1 20263. Only when an additional external force is applied, such as pushing the door body to make the piston 2 2027 move further, causing the hydraulic oil pressure to rise, can the thrust of the hydraulic oil overcome the elastic force of the disc spring 20266, push the piston 1 20263 to compress the disc spring 20266, and make the connecting hole 20262 open, thereby allowing the door body to continue to rotate.

[0020] Working principle: When the door opens, the upper hinge 201 and the lower hinge 204 rotate relative to each other, causing the frustum 2033 to move upwards along the slide groove 2035 within the connecting sleeve 2036 via the slider 2034. This compresses the spring 2032 via the frustum 2033. Simultaneously, the spline column 2031 slides within the key sleeve 2029, causing the connecting column 2028 to drive the piston 2027 to slide within the inner cylinder 2022. This allows the hydraulic oil in the upper part of the piston 2027 within the inner cylinder 2022 to flow back into the lower part of the piston 2027 within the inner cylinder 2022 through the upper oil drain groove 2024, the outer cylinder 2021, and the lower oil drain groove 2025. When the door is opened to 75°, the piston... As piston 2027 moves upward, it gradually blocks the upper oil drain groove 2024, increasing hydraulic oil resistance and reducing the door's opening speed to prevent it from hitting the wall. When piston 2027 completely blocks the upper oil drain groove 2024, hydraulic oil cannot flow, preventing piston 2027 from moving and thus the door from rotating. Continuing to push the door causes piston 2027 to rise further. The hydraulic oil above piston 2027 in the inner cylinder 2022 pushes piston 10263, compressing the lower disc spring 20266, allowing hydraulic oil to pass through the connecting hole 20262, thus enabling the door to rotate. When the door stops rotating, the lower disc spring 20266... 0266 drives piston 20263 to reset, blocking the connecting hole 20262, preventing the hydraulic oil from moving continuously and thus fixing the door's position. Similarly, when closing the door, pushing the door causes piston 2027 to move downwards within the inner cylinder 2022. The hydraulic oil below piston 2027 in the inner cylinder 2022 enters the upper part of the locking assembly 2026 within the inner cylinder 2022 via the lower drain groove 2025, the outer cylinder 2021, and the drain hole 2023. The hydraulic oil pushes piston 20263, compressing the upper disc spring 20266, allowing the hydraulic oil to pass through the connecting hole 20262, thus enabling the door to rotate. When the door is closed to below 75°... The compressed spring 2032 in the reset assembly 203 releases its elastic potential energy, pushing the frustum 2033 downward. Through the slider 2034 and the slide groove 2035, the connecting sleeve 2036 rotates, thereby driving the door to reset. At this time, the hydraulic oil at the bottom of the piston 2027 enters the space between the outer cylinder 2021 and the inner cylinder 2022 through the lower oil drain groove 2025, and then flows back to the upper part of the piston 2027 in the inner cylinder 2022 through the upper oil drain groove 2024. When the door is closed to 10°, the piston 2027 gradually blocks the lower oil drain groove 2025 during the downward movement, increasing the hydraulic oil resistance and reducing the door closing speed to avoid violent impact on the broken bridge door frame 1.

[0021] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
