A thermal insulation system for doors and windows

Abstract

This utility model relates to the field of door and window technology, specifically a heat-insulating system door and window, including a frame. Two doors and windows are slidably connected inside the frame. Roller compartments are installed on both sides of the top of each door and window. Insulating glass is installed inside each door and window. Sliding grooves are formed on both sides of the roller compartments, and positioning shafts are slidably connected inside the sliding grooves. Rollers are rotatably connected to the outer surface of the positioning shafts. Racks are longitudinally slidably connected to both sides of the inner wall of the roller compartments, and V-shaped rods are fixedly connected to the bottom of the racks. The advantages are: when the doors and windows are slidably closed, the racks in the roller compartments move upwards and protrude. When the doors and windows approach one side of the frame, the racks mesh with the drive gear, thereby driving a small gear one to rotate, a large gear one to rotate synchronously, and driving a small gear two to rotate. The counterweight wheel also rotates synchronously with the small gear two. Therefore, the doors and windows experience resistance and slow down. This design results in low noise and effectively improves closing efficiency.

Description

Technical Field

[0001] This utility model relates to the field of door and window technology, and in particular to a heat-insulating and heat-preserving system door and window. Background Technology

[0002] Doors and windows are classified as enclosure components or partition components according to their location, and have different design requirements. They must have functions such as heat preservation, heat insulation, sound insulation, waterproofing, and fireproofing. New requirements include energy conservation. In cold regions, heat loss through gaps in doors and windows accounts for about 25% of the total heating heat consumption. The airtightness of doors and windows is an important part of energy-saving design. Doors and windows are also important components of the building envelope system.

[0003] A thermally insulated aluminum alloy system door and window disclosed in Chinese Patent CN218862433U describes a system where, when the movable door and window are pushed quickly, the rollers rotate faster, causing a swing block mounted on the outer surface of the rotating shaft via a rotating rod to be thrown out under centrifugal force. This swing block applies a pushing force to an arc-shaped push block, which in turn pushes a crossbar towards a friction block via a guide rod. The crossbar then pushes the friction block downwards along the inner wall of the limiting groove via the inclined inner wall of the guide groove, causing the bottom of the friction block to abut against the bottom wall of the frame. This increases the resistance to pushing the movable door and window due to the increased friction between the frames, thereby reducing the speed at which the movable door and window are pushed and preventing strong collisions between the movable door and window and the sides of the frame, which could damage the movable door and window. However, while solving this problem, this thermally insulated aluminum alloy system door and window has the following drawbacks:

[0004] Multiple swing blocks, while rotating, apply thrust by colliding with the arc-shaped push blocks in sequence, which generates frequent collision sounds during use, resulting in significant noise. Furthermore, the friction blocks will be activated whenever the movable door or window moves quickly, making the entire process slow when the movable door or window moves from one side of the frame to the other, thus affecting the efficiency of opening and closing the movable door or window. Utility Model Content

[0005] The purpose of this utility model is to at least solve one of the technical defects described in the background art.

[0006] Therefore, one objective of this utility model is to propose a thermal insulation system for doors and windows, which aims to solve the problems of high noise and low efficiency in opening and closing of existing thermal insulation aluminum alloy system doors and windows.

[0007] To achieve the above objectives, one embodiment of the present invention provides a heat-insulating and heat-preserving system door and window, including a frame, two doors and windows are slidably connected inside the frame, roller compartments are installed on both sides of the top of the doors and windows, insulated glass is installed inside the doors and windows, sliding grooves are provided on both sides of the roller compartments, and a positioning shaft is slidably connected inside the sliding grooves, a roller is rotatably connected to the outer surface of the positioning shaft, and a rack is slidably connected longitudinally on both sides of the inner wall of the roller compartment, and a V-shaped rod is fixedly connected to the bottom of the rack;

[0008] The top of the frame has mounting slots on both sides, and a gearbox is fixedly installed in the mounting slot. A partition is fixedly connected to the middle of the gearbox, dividing the interior of the gearbox into two compartments. Each compartment is rotatably connected to a rotating shaft one, a rotating shaft two, and a rotating shaft three. Two drive gears are fixed to the outer surface of the rotating shaft one, and the drive gears protrude from the bottom of the gearbox and can mesh with the rack after it is raised.

[0009] The outer surface of the second rotating shaft is fixed with a small gear 1 that meshes with the driving gear, and a large gear 1 is fixedly connected to one side of the small gear 1. The outer surface of the third rotating shaft is fixed with a small gear 2 that meshes with the large gear 1, and a counterweight wheel is fixedly connected to one side of the small gear 2.

[0010] The beneficial effects are:

[0011] Firstly, when the door or window is sliding to close, the rack inside the roller chamber moves upward and protrudes. When the door or window approaches one side of the frame, the rack meshes with the drive gear, thereby driving the first pinion to rotate, the first large gear to rotate synchronously, and driving the second pinion to rotate. The counterweight wheel also rotates synchronously with the second pinion. As a result, the door or window will experience resistance and slow down, and then slowly fit against one side of the frame. Because of the rack and pinion transmission method, there is no frequent collision noise, resulting in low noise. Moreover, when closing the door or window, it only slows down when it approaches one side of the frame, thus effectively improving the closing efficiency.

[0012] Secondly, when opening doors and windows, slide the doors and windows, and the rollers slide along the slide groove through the positioning shaft, causing the rack to descend and fall into the roller chamber. The rack then disengages from the drive gear, allowing the doors and windows to be opened smoothly and easily.

[0013] Furthermore, two guide rails are fixedly connected to the bottom of the inner wall of the frame, and two guide grooves are opened at the top of the inner wall of the frame, with the two guide grooves corresponding to the two guide rails respectively.

[0014] Furthermore, the bottom of the door and window is provided with a guide rail groove, and multiple rollers are rotatably connected in the guide rail groove. The guide rail groove is sleeved on the outer surface of the guide rail, and the rollers can roll on the guide rail. The top of the door and window is slidably connected to the inside of the guide rail groove.

[0015] Furthermore, notches are provided at both ends of the guide groove corresponding to the positions of the drive gear. The drive gear protrudes through the notches into the guide groove, so that when the door or window slides and the rack protrudes, the rack can mesh with the drive gear when it passes the drive gear, thereby driving the drive gear to rotate.

[0016] Furthermore, positioning grooves are provided on both sides of the top of the door and window, and limiting grooves are provided on both sides of the positioning grooves. Limiting strips are fixedly connected to both sides of the roller compartment, and the limiting strips are inserted into the inside of the limiting grooves, thereby installing the roller compartment inside the positioning grooves.

[0017] Furthermore, vertical grooves are provided on both sides of the inner wall of the roller chamber, and a slider is fixedly connected to one side of the rack. The slider is slidably connected inside the vertical groove, and the two racks are fixedly connected together by a support rod, thereby preventing the slider from falling out of the vertical groove.

[0018] In a preferred embodiment, a groove is provided in the middle of the guide groove. When the door or window slides to the middle of the guide groove, there is no obstruction between the top of the door or window and the top of the roller. The door or window can be disassembled by lifting it upwards to disengage the guide groove from the guide rail, and then pulling the bottom of the door or window outwards.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] This utility model provides a system of doors and windows with thermal insulation.

[0033] Example 1:

[0034] like Figure 1 As shown, it includes a frame 1, two doors and windows 2 that are slidably connected within the frame 1, a roller compartment 3 and a gearbox 4, and insulated glass 21 is installed inside the doors and windows 2.

[0035] like Figure 2-3As shown, two guide rails 11 are fixedly connected to the bottom of the inner wall of the frame 1, and two guide grooves 12 are opened at the top of the inner wall of the frame 1, with the two guide grooves 12 corresponding to the two guide rails 11 respectively. A guide groove 22 is opened at the bottom of the door and window 2, and multiple rollers 23 are rotatably connected in the guide groove 22. The guide groove 22 is sleeved on the outer surface of the guide rails 11, and the top of the door and window 2 is slidably connected to the inside of the guide groove 12.

[0036] like Figure 4-6 As shown, positioning grooves 24 are provided on both sides of the top of the door and window 2, and limiting grooves 25 are provided on both sides of the positioning grooves 24. Limiting strips 31 are fixedly connected to both sides of the roller compartment 3. The limiting strips 31 are inserted into the inside of the limiting grooves 25, thereby installing the roller compartment 3 inside the positioning grooves 24. Sliding grooves 32 are provided on both sides of the roller compartment 3, and a positioning shaft 33 is slidably connected inside the sliding grooves 32. A roller 34 is rotatably connected to the outer surface of the positioning shaft 33. The roller 34 abuts against the top wall of the guide groove 12, and the roller 34 is made of rubber, so it has good quietness when rolling.

[0037] Vertical grooves 35 are provided on both sides of the inner wall of the roller chamber 3. A slider 36 is slidably connected inside the vertical groove 35. A rack 37 is fixedly connected to one side of the slider 36. The two racks 37 are fixedly connected together by a support rod 38 to prevent the slider 36 from falling out of the vertical groove 35. A V-shaped rod 39 is fixedly connected to the bottom of the rack 37. When the door and window 2 slides to the right, the roller 34 on the top right side of the door and window 2 rolls after encountering resistance. At the same time, the roller chamber 3 slides through the groove 32 on the surface of the positioning shaft 33. The sliding motion causes the positioning shaft 33 to move to the left side of the slide groove 32, thereby causing the inclined surface of the V-shaped rod 39 to rise along the positioning shaft 33, making the rack 37 protrude above the roller chamber 3. When the door and window 2 slides from right to left, the positioning shaft 33 moves to the rightmost side of the slide groove 32, and the rack 37 descends and retracts into the roller chamber 3. Similarly, when the door and window 2 slides to the left, the rack 37 on the top left side of the door and window 2 protrudes, and when the door and window 2 slides from left to right, the rack 37 on the top left side of the door and window 2 descends and retracts into the roller chamber 3.

[0038] like Figure 2-3 and Figure 7-8As shown, mounting slots 13 are provided on both sides of the top of the frame 1. A gearbox 4 is fixedly installed in the mounting slots 13. A partition 41 is fixedly connected in the middle of the gearbox 4, dividing the interior of the gearbox 4 into two compartments. Each compartment is rotatably connected to a rotating shaft 42, a rotating shaft 43, and a rotating shaft 44. Two drive gears 421 are fixed on the outer surface of the rotating shaft 42, and the drive gears 421 protrude from the bottom of the gearbox 4. Notches 14 are provided at both ends of the guide groove 12 at positions corresponding to the drive gears 421. The drive gears 421 protrude through the notches 14 and into the guide groove 12. Thus, when the door and window 2 slides and the rack 37 protrudes, the rack 37 can mesh with the drive gear 421 when it passes through the drive gear 421, thereby driving the drive gear 421 to rotate.

[0039] A small gear 431 that meshes with the drive gear 421 is fixed on the outer surface of the second shaft 43, and a large gear 432 is fixedly connected to one side of the small gear 431. A small gear 441 that meshes with the large gear 432 is fixed on the outer surface of the third shaft 44, and a counterweight wheel 442 is fixedly connected to one side of the small gear 441. Thus, the rotation of the drive gear 421 can drive the gears on the second shaft 43 and the third shaft 44 to rotate. Since the large gear drives the small gear, the resistance is large, which can effectively buffer and slow down the door and window 2.

[0040] Example 2:

[0041] like Figure 3 As shown, based on Embodiment 1, a groove 15 is provided in the middle of the guide groove 12. When the door and window 2 slides to the middle of the guide groove 12, there is no obstruction between the top of the door and window 2 and the top of the roller 34. The door and window 2 can be disassembled by lifting the door and window 2 upwards, causing the guide groove 22 to disengage from the guide rail 11, and then pulling the bottom of the door and window 2 outwards.

[0042] The working principle of this utility model is as follows: When the door and window 2 is slid to one side of the frame 1 to close, the rack 37 in the roller chamber 3 moves upward and protrudes. When the door and window 2 approaches one side of the frame 1, the rack 37 meshes with the drive gear 421, thereby driving the small gear 431 to rotate, the large gear 432 to rotate synchronously, and driving the small gear 441 to rotate. The counterweight wheel 442 rotates synchronously with the small gear 441. Therefore, the door and window 2 will be slowed down by resistance and then slowly adhere to one side wall of the frame 1.

[0043] When the door and window 2 are opened, the sliding door and window 2 is slidable, and the roller 34 slides along the slide groove 32 through the positioning shaft 33, so that the rack 37 falls into the roller chamber 3. The rack 37 then disengages from the drive gear 421, so that the door and window 2 can be opened smoothly and easily.
