Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and more specifically, the utility model relates to a temporary fixing device for window and door frames during installation. Background Technique

[0002] In the field of modern building construction, the accuracy and efficiency of window and door frame installation have crucial impacts on the overall quality of the building and the construction progress. However, a series of severe challenges are faced in the current temporary fixing link during window and door frame installation.

[0003] Most traditional temporary fixing methods rely on manual experience and simple tools. Construction workers often use wooden wedges or bricks and stones to resist the window and door frames for fixation. This method has great instability. Wooden wedges are easily affected by environmental humidity. When they get wet, they expand, and when they dry, they shrink, resulting in a weakened fixing force, causing the window and door frames to displace during subsequent construction; although bricks and stones can provide certain support, it is difficult to accurately position and fine-tune them, and it is impossible to ensure the verticality and horizontality of the window and door frames, thus affecting the installation accuracy of the windows and doors. This accuracy deviation will not only reduce the sealing performance of the windows and doors, resulting in problems such as air leakage and water leakage, but also affect the smoothness of window and door opening and shorten the service life of the windows and doors.

[0004] In addition, with the increasing diversification of building styles, the designs of windows and doors are becoming more novel and complex, and the size specifications vary greatly. Traditional and existing fixing devices are becoming increasingly inadequate when facing these new types of windows and doors, and they cannot provide reliable temporary fixing solutions, resulting in increased construction costs and extended construction periods.

[0005] Therefore, a temporary fixing device for window and door frames during installation is proposed. Content of the Utility Model

[0006] In order to overcome the above-mentioned defects of the prior art, the utility model provides a temporary fixing device for window and door frames during installation to solve the problems raised in the above background technique.

[0007] To achieve the above object, the utility model provides the following technical solution: A temporary fixing device for window and door frames during installation, including a moving chassis, a pillar is installed on the moving chassis, a lifting mechanism is installed on one side of the pillar, a fixing frame is installed on the lifting mechanism, a fixing frame is welded at one end of the fixing frame, and a plurality of top fixing components are installed on the fixing frame.

[0008] The door and window frames are internally fixed by various top-fixing components. Then, the movable base moves the door and window frames to the desired installation location and aligns them. The lifting mechanism then raises and lowers the fixing frame, changing the height of the door and window frames fixed by the various top-fixing components. This adjusts the height of the door and window frames. Finally, the movable base moves to position the door and window frames within the installation window and locks its position, thus temporarily fixing the door and window frames. The operation is simple, convenient, and easy to disassemble, improving the efficiency of door and window installation.

[0009] Preferably, the bottom of the mobile chassis is provided with multiple sets of rollers, each of which is a self-locking omnidirectional wheel.

[0010] Preferably, the lifting mechanism includes a motor, a lead screw, a guide rail, and a slide block. The motor is installed at the bottom of one side of the support column, the output end of the motor is connected to the lead screw, the guide rails are provided on both sides of the lead screw, the slide block is sleeved on the lead screw, the two sides of the slide block are slidably connected to the guide rails, and the fixing frame is installed on the slide block.

[0011] Preferably, there are three top-fixing components, and the top-supporting directions of the three top-fixing components are all different.

[0012] Preferably, the top-fixing assembly includes a screw, a knob, a bearing, a top-fixing plate, and a guide rod. One end of the screw is connected to the top-fixing plate via the bearing, and the other end of the screw is provided with a knob. The top-fixing plate has a guide rod parallel to the screw.

[0013] Preferably, the fixed frame has a screw hole for screwing the screw, and through holes for sliding connection with the guide rod are provided on both sides of the screw hole.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] By using the internal bracing of the top-fixed components to fix the door and window frames, moving the mobile chassis to the installation window and aligning it, adjusting the height through the lifting mechanism, and then moving the chassis to position and lock the door and window frames, the entire process is simple to operate, easy to disassemble, and greatly improves the efficiency of door and window installation.

[0016] The chassis features self-locking casters at the bottom, allowing for easy and flexible movement of the fixing devices. Once positioned, the devices are effectively fixed, preventing movement from affecting the door and window frame's position and ensuring the aesthetic appeal of the completed door and window installation.

[0017] With three top-fixing components in different directions, the position of the top-fixing plate can be adjusted by screws and knobs to meet the fixing needs of door and window frames of different sizes, thus improving the practicality of the fixing device.

[0018] With the setup of a motor, lead screw, guide rail, and slide, the motor drives the lead screw to rotate, causing the slide to rise and fall along the guide rail, precisely adjusting the height of the fixing frame to meet the temporary fixing requirements of door and window frames of different heights.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] As attached Figures 1-4 The temporary fixing device for installing door and window frames shown includes a mobile base 1, a support column 2 installed on the mobile base 1, a lifting mechanism 3 installed on one side of the support column 2, a fixing frame 4 installed on the lifting mechanism 3, a fixing frame 5 welded to one end of the fixing frame 4, and multiple top fixing components 6 installed on the fixing frame 5.

[0026] In practice, the door and window frame 100 is internally fixed by each top-fixing component 6. Then, the door and window frame 100 is moved to the window to be installed by the movable base 1 and aligned. Then, the lifting mechanism 3 is operated to raise and lower the fixing frame 4, thereby changing the height of the door and window frame 100 fixed by each top-fixing component 6 on the fixing frame 5, thus adjusting the height of the door and window frame 100. Then, the movable base 1 is moved so that the door and window frame 100 is in the window to be installed. The position of the movable base 1 is locked, thus completing the temporary fixing of the door and window frame 100. The operation is simple, convenient to use, and easy to disassemble, improving the efficiency of door and window installation.

[0027] The bottom of the mobile chassis 1 is equipped with multiple sets of rollers, each of which is a self-locking omnidirectional wheel.

[0028] In practice, the self-locking casters allow for easy movement of the fixing device to any position while maintaining its position. This prevents the fixing device from moving after the door and window frame 100 is fixed, thus improving the stability of the door and window frame 100 and enhancing the aesthetics of the completed door and window installation.

[0029] The lifting mechanism 3 includes a motor 301, a lead screw 302, a guide rail 303, and a slide 304. The motor 301 is installed at the bottom of one side of the support column 2. The output end of the motor 301 is connected to the lead screw 302. The guide rail 303 is provided on both sides of the lead screw 302. The slide 304 is sleeved on the lead screw 302. The two sides of the slide 304 are slidably connected to the guide rail 303. The fixing frame 4 is installed on the slide 304.

[0030] In practice, the motor 301 is operated, causing the lead screw 302 to rotate, which in turn causes the slide 304 to rise and fall along the guide rail 303. This allows the height of the fixing frame 4 to be adjusted, thereby adjusting the height of the door and window frames 100 that are supported and fixed by each top fixing component 6, so as to temporarily fix the door and window frames 100 at different heights.

[0031] There are three top-fixing components 6, and the supporting directions of the three top-fixing components 6 are all different.

[0032] The top-fixing assembly 6 includes a screw 601, a knob 602, a bearing 603, a top-fixing plate 604, and a guide rod 605. One end of the screw 601 is connected to the top-fixing plate 604 through the bearing 603, and the other end of the screw 601 is provided with a knob 602. The top-fixing plate 604 has a guide rod 605 parallel to the screw 601.

[0033] The fixed frame 5 has a screw hole that is screwed to the screw 601, and through holes that are slidably connected to the guide rod 605 are provided on both sides of the screw hole.

[0034] In practice, by rotating the knob 602, the screw 601 rotates within the screw hole, allowing it to extend or retract, thus adjusting the external support position of the top fixing plate 604. Combined with the guidance of the two guide rods 605, this ensures the stable external support of the top fixing plate 604. The external support of the top fixing plate 604 abuts against the inner edge of the door / window frame 100. With the support of multiple top fixing plates 604, the door / window frame 100 is securely fixed. Since the screw 601 can adjust the support position of the top fixing plate 604, it is convenient to use with door / window frames 100 of different sizes, improving the practicality of the fixing device.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
