Description

A type of combined thermal insulation door and window profile Technical Field

[0001] This invention relates to the field of door and window profile technology, specifically to a combined thermal insulation door and window profile. Background Technology

[0002] When assembling doors and windows, profiles are used to form window frames that hold the glass panels in place, together with the glass panels to form a complete door or window system. Commonly used door and window profiles are usually made of aluminum alloy or PVC, and the profiles are generally processed into shape through processes such as raw material melting, die extrusion, and straightening.

[0003] For example, the invention patent with publication number CN202110102860.6, entitled "A Combined Thermal Insulation Door and Window Profile and Its Preparation Method," includes a supporting frame with a hollow rectangular cross-section. A through groove extending along the length of the supporting frame is formed on one side wall. A closed frame is provided inside the supporting frame, with each outer side wall of the closed frame abutting against one of the inner side walls of the supporting frame. Several closed ends are provided within the closed frame, with two adjacent closed ends forming a group. The closed ends in the same group together form a sealed space within the closed frame, and this sealed space is subjected to negative pressure. A connecting end is provided at the bottom of the outer wall of the supporting frame, and a glass fixing end is provided on the side wall of the supporting frame. This application improves the thermal insulation performance of the window frame made from the profile by reducing heat and sound transmission between the two sides of the profile through the closed frame and the formation of several closed, negative pressure spaces within the closed frame via the closed ends.

[0004] The assembly of existing doors and windows requires multiple sets of corner brackets and a large number of screws. Since the corner brackets are usually installed tightly, workers need to use wooden hammers to tap the window frame components during assembly to help them fit together. Summary of the Invention

Detailed Implementation

[0027] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Please refer to Figures 1-7. A combined thermal insulation door and window profile includes a first outer rod 1, a second outer rod 5, and a central rod 2. It also includes: a connecting mechanism, which is disposed within each of the first outer rods 1 and the second outer rods 5, and the first outer rods 1 and the second outer rods 5 are combined to form a window frame through the connecting mechanism; and a locking mechanism, which is disposed on the central rod 2. When the first outer rods 1 and the second outer rods 5 are combined, the locking mechanism will simultaneously lock the first outer rods 1, the second outer rods 5, and the central rod 2.

[0029] In another embodiment of the present invention: the second outer rod 5 includes two outer frames, the connecting mechanism includes an inner frame 303 disposed between the two outer frames, and a connecting frame 302 is fixedly connected to both outer frames, and a connecting rod 301 is fixedly connected to the inner wall of the first outer rod 1; the two outer frames are snapped together, and four connecting rods 301 are fixedly connected to the inner wall of the first outer rod 1, and two connecting rods 301 on the same side are respectively located on both sides of the inner frame 303, wherein the connecting frame 302 on the outer frame is also located on both sides of the inner frame 303. When the two outer frames are connected together, the first outer rod 1 is moved toward the second outer rod 5, and at this time the two connecting rods 301 on the same side of the first outer rod 1 will be inserted into the connecting frame 302 of the two outer frames at the same time, thereby strengthening the connection between the two outer frames;

[0030] In another embodiment of the present invention: each outer frame has a protrusion 312 fixedly connected to its inner wall, and each inner frame 303 has a groove adapted to the protrusion 312 on its surface; when the two outer frames are engaged and snapped together, the protrusion 312 on them will be inserted into the inner frame 303 through the groove, thereby installing the inner frame 303 in the second outer rod 5.

[0031] In another embodiment of the present invention: a plug rod 304 is horizontally slidably inserted into the built-in frame 303, and a fixing block 305 is fixedly connected to the inner wall of the first outer rod 1. The fixing block 305 has a slot 3051 adapted to the plug rod 304. The plug rod 304 is driven by the locking mechanism to be inserted into the slot 3051. When the atrium rod 2 is inserted into the window frame of the combination of the first outer rod 1 and the second outer rod 5, the locking mechanism can drive the plug rod 304 to move. At this time, the plug rod 304 will be inserted into the slot 3051. Because the first outer rod 1 and the second outer rod 5 are tightly fitted together, and the connecting rod 301 is inserted into the connecting frame 302, the movement of the first outer rod 1 away from the second outer rod 5 is restricted. Then, when the insert rod 304 is inserted into the slot 3051, the fit between the insert rod 304 and the slot 3051 will restrict the movement of the second outer rod 5 away from the first outer rod 1. The cross-section of the slot 3051 is triangular, so that after the tip of the insert rod 304 is inserted into the slot 3051, the insert rod 304 cannot move upward.

[0032] In another embodiment of the present invention: the locking mechanism includes an abutment rod 307 vertically slidably installed in the atrium rod 2, and two insertion rods 304 are provided with abutment slopes at their ends close to each other. A triangular block is fixedly installed at the end of the abutment rod 307 close to the insertion rod 304. Through holes for inserting the abutment rod 307 are provided on the first outer rod 1 and the second outer rod 5. The cross section of the triangular block is specifically an isosceles triangle. The two equal sides of the isosceles triangle are respectively aligned with the abutment slopes of the two insertion rods 304. When the atrium rod 2 is inserted between the first outer rod 1 and the second outer rod 5, the abutment rod 307 is moved toward the insertion rod 304. At this time, the sides of the triangular block will squeeze the insertion rod 304 through the abutment slopes. At this time, the two insertion rods 304 in the second outer rod 5 will move away from each other and thus be inserted into the slot 3051.

[0033] In another embodiment of the present invention: a limiting plate 306 is fixedly connected to the insertion rod 304, and a spring is fixedly connected between the limiting plate 306 and the inner frame 303; wherein an elongated groove is opened on the surface of the insertion rod 304, and the spring is disposed in the elongated groove. The spring can be easily installed through the elongated groove. When the insertion rod 304 is inserted into the slot 3051, the spring will be compressed until the abutment rod 307 is removed. At this time, the spring will restore its elasticity, thereby driving the insertion rod 304 to move out of the slot 3051, thereby facilitating the disassembly of the first outer rod 1 and the second outer rod 5 after the atrium rod 2 is removed.

[0034] In another embodiment of the present invention: a driving mechanism is further provided on the atrium rod 2. The driving mechanism includes a cylinder 309 rotatably mounted on the atrium rod 2. A first bevel gear 3091 is coaxially fixedly connected to the cylinder 309. A sleeve 311 is rotatably mounted inside the atrium rod 2. A second bevel gear 310, which meshes with the first bevel gear 3091, is coaxially fixedly spaced on the sleeve 311. A bidirectional screw 308 is fixedly connected to the inner wall of the sleeve 311. The two ends of the bidirectional screw 308 are threadedly connected to two abutment rods 307 respectively. When the cylinder 309 is rotated, the cylinder 309 will drive the first bevel gear 3091 to rotate. At this time, the first bevel gear 3091 will drive... When the second bevel gear 310 rotates, it will drive the sleeve 311 to rotate. As the sleeve 311 rotates, it will drive the bidirectional screw 308 to rotate. The two ends of the bidirectional screw 308 are respectively provided with threaded grooves in opposite directions. When the bidirectional screw 308 rotates, it will drive the two abutting rods 307 to move away from each other or closer to each other. The insert rod 304, the inner frame 303, the first outer rod 1, the second outer rod 5, the central rod 2, and the abutting rod 307 are all made of heat-insulating profiles. When the insert rod 304 and the inner frame 303 are set inside the second outer rod 5, the second outer rod 5 can also achieve a better heat insulation effect.

[0035] In another embodiment of the present invention: a flat slot 3092 is provided at the end of the cylinder 309 away from the first bevel gear 3091; the flat slot 3092 facilitates the rotation of the cylinder 309 using a screwdriver, coin or other tools;

[0036] In another embodiment of the present invention: a cover plate 41 is slidably inserted on the atrium rod 2, and a screw 42 threadedly connected to the atrium rod 2 is inserted on the cover plate 41; after the cylinder 309 is adjusted, the cover plate 41 is inserted into the atrium rod 2, at which time the cover plate 41 will cover the surface of the cylinder 309, and the screw 42 is tightened at the same time. At this time, the screw 42 will drive the cover plate 41 to move into the atrium rod 2, thereby pressing the cylinder 309 through the cover plate 41, thereby preventing the cylinder 309 from rotating randomly;

[0037] In another embodiment of the present invention: a rubber pad is fixedly connected to one end of the cover plate 41 near the cylinder 309; the rubber pad increases elasticity and friction, thereby making the compression and limiting effect of the cover plate 41 on the cylinder 309 better;

[0038] Working principle: Two outer frames are snapped together, and four connecting rods 301 are fixedly connected to the inner wall of the first outer rod 1. Two connecting rods 301 on the same side are located on either side of the inner frame 303. Connecting frames 302 on the outer frame are also located on either side of the inner frame 303. When the two outer frames are connected together, the first outer rod 1 is moved towards the second outer rod 5. At this time, the two connecting rods 301 on the same side of the first outer rod 1 will simultaneously insert into the connecting frames 302 of the two outer frames, thereby strengthening the connection between the two outer frames. When the two outer frames are snapped together, their… The protrusion 312 on the upper part will be inserted into the inner frame 303 through the groove, thereby installing the inner frame 303 inside the second outer rod 5; when the atrium rod 2 is inserted into the window frame of the combination of the first outer rod 1 and the second outer rod 5, the locking mechanism can drive the insertion rod 304 to move. At this time, the insertion rod 304 will be inserted into the slot 3051. At this time, due to the tight fit between the first outer rod 1 and the second outer rod 5, and the insertion of the connecting rod 301 into the connecting frame 302, the movement of the first outer rod 1 away from the second outer rod 5 is restricted. Then, after the insertion rod 304 is inserted into the slot 3051, the insertion rod 304... The engagement of 04 and slot 3051 restricts the movement of the second outer rod 5 away from the first outer rod 1. The slot 3051 has a triangular cross-section, preventing the tip of the insertion rod 304 from moving upwards after insertion into the slot 3051. Specifically, the triangular block has an isosceles triangle cross-section, with its two equal sides aligned with the abutting slopes of the two insertion rods 304. When the central rod 2 is inserted between the first outer rod 1 and the second outer rod 5, the abutting rod 307 moves towards the insertion rod 304, at which point the triangular block... The waist will press the insert rod 304 by abutting the inclined side. At this time, the two insert rods 304 in the second outer rod 5 will move away from each other and be inserted into the slot 3051. The surface of the insert rod 304 is provided with a long groove, and the spring is set in the long groove. The long groove can be used to install the spring. When the insert rod 304 is inserted into the slot 3051, the spring will be compressed until the abutting rod 307 is removed. At this time, the spring will restore its elasticity and drive the insert rod 304 out of the slot 3051, so that the first outer rod 1 and the second outer rod 5 can be easily disassembled after the central rod 2 is removed.When the cylinder 309 is rotated, it drives the first bevel gear 3091 to rotate. The first bevel gear 3091 then drives the second bevel gear 310 to rotate, which in turn drives the sleeve 311 to rotate. The rotation of the sleeve 311 drives the bidirectional screw 308 to rotate. The bidirectional screw 308 has oppositely oriented threaded grooves at both ends. When the bidirectional screw 308 rotates, it drives the two abutment rods 307 to move away from or towards each other. The insertion rod 304, the inner frame 303, the first outer rod 1, the second outer rod 5, the central rod 2, and the abutment rods 307 are all made of heat-insulating profiles. When rod 304 and inner frame 303 are set inside the second outer rod 5, the second outer rod 5 can also provide better heat insulation. The flat slot 3092 allows for easy rotation of cylinder 309 using screwdriver 42, coins, or other tools. After cylinder 309 is adjusted, cover plate 41 is inserted into the atrium rod 2. Cover plate 41 then covers the surface of cylinder 309. Tightening screw 42 causes screw 42 to move cover plate 41 into the atrium rod 2, thus pressing cylinder 309 and preventing it from rotating freely. The rubber pad increases elasticity and friction, further enhancing the pressing and limiting effect of cover plate 41 on cylinder 309.

[0039] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
