Description

Technical Field

[0001] The utility model relates to the field of building decoration, and particularly to a window frame installation structure. Background Art

[0002] A window frame refers to the transition layer between a wall and a window. It not only plays a role in fixing the window but also prevents the surrounding wall from collapsing.

[0003] During the installation process of the window frame, a series of steps need to be followed to ensure the installation quality and stability. The main steps of window frame installation include: Measurement: Before installing the window frame, it is first necessary to accurately measure the dimensions of the window opening, including height, width, depth, etc., to ensure that the window frame can perfectly match the opening. Install the window frame: Place the window frame in the opening, ensure its correct position and maintain an appropriate gap with the edge of the opening. Use the pre-drilling method to drill holes in the window frame and the wall for installing screws or expansion bolts. Pass the screws or expansion bolts through the fixing holes of the window frame and screw them into the wall to ensure that the window frame is firmly fixed on the wall. Adjust the position and angle of the window frame to keep it horizontal and vertical, ensuring that the installed window can be smoothly opened and closed. Sealing treatment: Fill the gap between the window frame and the wall with sealant or foaming agent to prevent wind and rain from entering the room. At the same time, ensure that the sealant or foaming agent is completely cured to achieve the best sealing effect. Inspection and adjustment: After installation, inspect and adjust the window frame. Check whether the window frame is stable, whether the sealing is good, and whether the window can be smoothly opened and closed, etc.

[0004] However, in actual use of the existing technology, since most existing window frames are made of metal and are relatively large in size, the process of carrying and placing the window frame in the window opening for installation is rather cumbersome and inconvenient. At the same time, it is necessary to temporarily fix the window frame placed in the window opening to ensure the stability of the window frame during installation and avoid the situation of the window frame tilting and falling. As a result, during the installation of the window frame, due to the cumbersome operations of carrying, placing, and temporary fixing, the installation efficiency of the window frame is affected.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-4 , the present utility model provides a technical solution for a window frame installation structure: including a main frame 1, two balance frames 2 are fixedly installed on both sides of the lower end of the main frame 1, and the number of balance frames 2 is two, symmetrically distributed on both sides of the lower end of the main frame 1. The front end of the balance frame 2 is rotatably connected to the front support roller 3 through a pin shaft, and the rear side of the lower end of the main frame 1 is rotatably connected to the rear support roller 4 through a pin shaft. The number of rear support rollers 4 is two, symmetrically distributed on the rear side of the lower end of the main frame 1, so that it is convenient to push and move the main frame 1 by cooperating the rear support roller 4 with the front support roller 3. A power control cabinet 5 is fixedly installed on the rear side of the upper end of the main frame 1, and a mobile power source is fixedly installed inside the power control cabinet 5;

[0026] On the inner side of the lower end of the main body frame 1, a hydraulic lifting rod 6 is fixedly installed.

On both sides of the telescopic part of the upper end of the hydraulic lifting rod 6, pulley wheels 9 are rotatably connected by a rotating shaft. There are two pulley wheels 9, which are symmetrically distributed on both sides of the telescopic part of the upper end of the hydraulic lifting rod 6. On the rear side of the middle part of the main body frame 1, a T-shaped frame 10 is fixedly installed. The upper end of the pulley wheel 9 is in frictional transmission connection with a lifting belt 11, and the rear end of the lifting belt 11 is fixedly installed on both sides of the lower end of the T-shaped frame 10. The lower end of the lifting belt 11 is fixedly installed with a lifting platform 12. On both sides of the rear end of the lifting platform 12, limit wheels 13 are rotatably connected by a pin shaft. A limit groove 14 is opened on the inner side of the main body frame 1, and the limit wheels 13 are in frictional and movable connection with the inner wall of the limit roller groove 14, so that the lifting platform 12 is linearly moved and limited by the cooperation of the limit wheels 13 and the limit groove 14;

[0027] In the middle of the front end of the lifting platform 12, a first driving screw 15 is rotatably supported by a bearing seat. The thread directions of the outer curved surfaces on both sides of the first driving screw 15 are opposite. Clamping platforms 16 are threadedly connected to the outer curved surfaces on both sides of the first driving screw 15. There are two clamping platforms 16, which are symmetrically distributed on the outer curved surfaces on both sides of the first driving screw 15. The upper and lower ends of the clamping platforms 16 respectively penetrate and are in frictional and movable connection with limit sliding rods 17, and both sides of the limit sliding rods 17 are fixedly installed on the front end of the lifting platform 12, so that the clamping platforms 16 are linearly moved and limited by the limit sliding rods 17. On the rear end of the lifting platform 12, a first driving motor 18 is fixedly installed. On the transmission shaft part of the side end of the first driving motor 18, a first synchronous wheel 19 is fixedly installed. The outer end of the first synchronous wheel 19 is in transmission connection with a second synchronous wheel 20 through a synchronous belt, and the second synchronous wheel 20 is fixedly installed on the outer curved surface of the side end of the first driving screw 15. On the front end of the clamping platform 16, a clamping arm 21 is fixedly installed. On the front side end of the clamping arm 21, a fixed clamping plate 22 is fixedly installed. On the outer side of the upper end of the clamping arm 21, a limit straight chute 23 is opened. On the front end of the clamping arm 21, a second driving motor 24 is fixedly installed. The transmission shaft part of the rear end of the second driving motor 24 penetrates the front end of the clamping arm 21 and is fixedly installed with a second driving screw 25, and the second driving screw 25 is rotatably connected to the inner wall of the limit straight chute 23 by a rotating shaft. A slider 26 is threadedly connected to the outer curved surface of the rear end of the second driving screw 25, and the slider 26 is in frictional and movable connection with the inner wall of the limit straight chute 23, so that the slider 26 is linearly moved and limited by the limit straight chute 23. On the outer side of the slider 26, a movable clamping plate 27 is fixedly installed, and the movable clamping plate 27 and the fixed clamping plate 22 are on the same horizontal line.

[0028] Working principle: When in use, the utility model moves and extends the clamping arm 21 to the inner side of the window frame to be installed by pushing the main body frame 1. When the clamping arm 21 moves and extends to the inner side of the window frame, the first driving motor 18 is controlled to be turned on. When the first driving motor 18 is turned on, it drives the first synchronous pulley 19 to rotate. When the first synchronous pulley 19 rotates, it drives the second synchronous pulley 20 to rotate through synchronous belt transmission. When the second synchronous pulley 20 rotates, it drives the first transmission screw 15 to rotate. The thread directions of the outer curved surfaces on both sides of the first transmission screw 15 are opposite, so that when the first transmission screw 15 rotates, it synchronously drives the clamping table 16 to linearly move outward along the outer curved surface of the limit slide bar 17. When the clamping table 16 linearly moves outward synchronously, it drives the clamping arm 21 to linearly move outward and open. When the clamping arm 21 linearly moves outward and opens, the clamping arm 21 will open and fit against the inner wall of the window frame. When the clamping arm 21 opens and fits against the inner side of the window frame, the second driving motor 24 is controlled to be turned on. When the second driving motor 24 is turned on, it drives the second transmission screw 25 to rotate. When the second transmission screw 25 rotates, due to the acting force generated by screw connection, it drives the slider 26 to linearly move forward along the inner wall of the limit straight chute 23. When the slider 26 linearly moves forward, it drives the moving clamping plate 27 to linearly move forward. When the moving clamping plate 27 linearly moves forward, it cooperates with the fixed clamping plate 22 to clamp and fix the window frame, thereby realizing the function of facilitating the temporary clamping and fixing of the window frame to be installed.

[0029] At the same time, when the window frame is clamped and fixed, by swinging the pressing lever control rod 8 downward, when the lever control rod 8 is swung and pressed downward, it controls the opening of the control hydraulic cylinder 7. When the control hydraulic cylinder 7 is turned on, it drives the hydraulic lifting rod 6 to extend upward. When the hydraulic lifting rod 6 extends upward, it drives the pulley 9 to linearly move upward. When the pulley 9 linearly moves upward, it drives the lifting table 12 to linearly move upward through the lifting belt 11. When the lifting table 12 linearly moves upward, it synchronously drives the clamping arm 21 to linearly move upward. When the clamping arm 21 linearly moves upward, it drives the clamped and fixed window frame to be lifted upward, thereby realizing that while facilitating the clamping and fixing of the window frame, the clamped and fixed window frame can be lifted and transported to the window opening for installation.
