Technical Field

[0001] The utility model relates to the technical field of door and window installation, in particular to an adjustable door and window installation bracket. Background Art

[0002] In the modern construction field, doors and windows, as basic components of buildings, are not only related to the aesthetics, lighting and ventilation of houses, but also directly related to the safety, comfort and energy efficiency of living and use. With the development of the construction industry and the improvement of people's requirements for the quality of life, the installation technology and techniques of doors and windows have also been continuously improved to meet the increasingly complex building design requirements and more stringent construction standards.

[0003] Although the existing door and window installation brackets can temporarily fix the door and window frames, they lack an effective adjustment mechanism. As a result, in the face of actual situations such as uneven walls or slight deviations in the sizes of door and window openings, it is difficult to make precise position or angle adjustments and it is impossible to adapt to different sizes of door and window frames. This not only limits the flexibility of installation, but may also affect the sealing performance of doors and windows and the overall aesthetics of the building, increasing the installation difficulty and the complexity of later adjustments. Content of the Utility Model

[0004] In order to overcome the shortcoming that the existing door and window installation brackets cannot adapt to different sizes of door and window frames when installing doors and windows, the purpose of the utility model is to provide an adjustable door and window installation bracket that can adapt to different sizes of doors and windows.

[0005] An adjustable door and window installation bracket includes a robotic arm, a mounting bracket, a stretching mechanism, a biaxial motor, a wire reel, a first pulling rope, a second pulling rope and a clamping assembly. A mounting bracket is fixedly connected to the robotic arm. Two upper and lower stretching mechanisms are respectively connected to both the left and right sides of the mounting bracket.

The first pulling rope is fixedly connected to the second sliding rod of the third stretching mechanism. Clamping assemblies are respectively connected to the top of the first sliding rod and the bottom of the second sliding rod of the third stretching mechanism.

[0006] As an improvement to the above solution, the clamping assembly includes a fixed block, a movable plate, a guide rod, a bidirectional lead screw, and a buffer assembly. Fixed blocks are fixedly connected to the top of the first sliding rod and the bottom of the second sliding rod of the third stretching mechanism. The upper fixed block is fixedly connected to the second pulling rope. Bidirectional lead screws are rotatably connected to the fixed blocks, and guide rods are fixedly connected to the fixed blocks.

Specific embodiments

[0018] References to embodiments in this text mean that the specific features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of the present utility model. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0019] An adjustable window and door mounting bracket, as Figures 1 - 5 shown, includes a robotic arm 1, a mounting bracket 2, a stretching mechanism, a biaxial motor 6, a wire winding cylinder 7, a first pulling rope 9, a second pulling rope 10, and a clamping assembly. The mounting bracket 2 is fixedly connected to the robotic arm 1. Both the left and right sides of the mounting bracket 2 are connected with two stretching mechanisms, one above the other. A third stretching mechanism is connected between the upper and lower stretching mechanisms. The biaxial motor 6 is installed at the bottom of the mounting bracket 2. Two wire winding cylinders 7 are fixedly connected to the output shafts of the biaxial motor 6. The first pulling rope 9 is connected to the wire winding cylinder 7 close to the biaxial motor 6, and the second pulling rope 10 is connected to the wire winding cylinder 7 far from the biaxial motor 6. Both the first pulling rope 9 and the second pulling rope 10 are steel wires. Clamping assemblies are connected to both the upper and lower sides of the third stretching mechanism. The second pulling rope 10 is connected to the upper clamping assembly. The stretching mechanism includes a first sliding rod 3, a second sliding rod 4, and a first elastic member 5. Two first sliding rods 3 are fixedly connected to both the left and right sides of the mounting bracket 2. The first elastic member 5 is fixedly connected inside the first sliding rod 3. The first elastic member 5 is a strong spiral spring. The second sliding rod 4 is slidably connected to the first sliding rod 3. The first elastic member 5 is fixedly connected to the second sliding rod 4. The second sliding rods 4 are fixedly connected to the second sliding rods 4 of the third stretching mechanism. The first pulling rope 9 is fixedly connected to the second sliding rod 4 of the third stretching mechanism. Clamping assemblies are connected to both the top of the first sliding rod 3 and the bottom of the second sliding rod 4 of the third stretching mechanism.

[0020] At first, both the first pulling rope 9 and the second pulling rope 10 are in a taut state. Under the tensile action of the first pulling rope 9 and the second pulling rope 10, the first elastic members 5 are all in a compressed state. When installing the door and window frame, first place the door and window frame in the upper clamping assembly, and then drive the wire winding cylinder 7 to rotate through the double-axis motor 6, so that the wire winding cylinder 7 releases the first pulling rope 9 and the second pulling rope 10 thereon. During this process, the first elastic members 5 all return to their original states, causing the first sliding rods 3 to gradually move away from the second sliding rods 4, so that the clamping assembly gradually contacts the inner wall of the door and window frame, and then the clamping assembly can be used to clamp the door and window frame. It can enable the clamping assembly to clamp door and window frames of different sizes, improving the installation efficiency of the door and window frame. When it is necessary to retract the clamping assembly, reverse the wire winding cylinder 7 through the double-axis motor 6.

[0021] As Figure 1 、 Figure 2 and Figure 4 shown, the clamping assembly includes a fixed block 12, a movable plate 13, a guide rod 14, a bidirectional lead screw 15 and a buffer assembly. Fixed blocks 12 are fixedly connected to the top of the first sliding rod 3 and the bottom of the second sliding rod 4 of the third stretching mechanism. The upper fixed block 12 is fixedly connected to the second pulling rope 10. Bidirectional lead screws 15 are rotatably connected to the fixed blocks 12. Rotating handles are fixedly connected to both ends of the bidirectional lead screws 15, which is convenient for the use of the bidirectional lead screws 15. Guide rods 14 are fixedly connected to the fixed blocks 12. Movable plates 13 are slidably connected to the front and rear sides of the fixed blocks 12 through the guide rods 14. The movable plates 13 are all threadedly connected to the bidirectional lead screws 15. Buffer assemblies are connected to the sides where the front and rear movable plates 13 are close to each other. The buffer assembly includes a pressing plate 17, a second elastic member 18 and a rubber plate 19. Pressing plates 17 are slidably connected to the sides where the front and rear movable plates 13 are close to each other. Four second elastic members 18 are fixedly connected between the pressing plates 17 and the movable plates 13. The second elastic members 18 are spiral springs. Rubber plates 19 are fixedly connected to the sides where the front and rear pressing plates 17 are close to each other. The rubber plates 19 can increase the friction between the door and window frame and the pressing plates 17, preventing the pressing plates 17 from scratching the door and window frame.

[0022] When it is necessary to fix the door and window frame, place the inner top of the door and window frame on the upper fixed block 12, and rotate the bidirectional lead screw 15 to make the front and rear movable plates 13 approach each other, so that the buffer assemblies approach each other to clamp the door and window frame, thus completing the clamping and fixing of the door and window frame and preventing it from falling off during the installation of the door and window frame. When the front and rear movable plates 13 approach each other, the rubber plate 19 presses the outer wall of the door and window frame, and the second elastic member 18 is compressed, which can prevent the surface of the door and window frame from being sunken during clamping.

[0023] As Figure 1 and Figure 2As shown, it further includes a first guide sleeve 8 and a second guide sleeve 11. The first guide sleeves 8 are fixedly connected to both the left and right sides of the mounting bracket 2, and the second guide sleeves 11 are fixedly connected to the second sliding rods 4 of the third stretching mechanism. The first pulling rope 9 and the second pulling rope 10 both pass through the first guide sleeve 8, and the second pulling rope 10 passes through the second guide sleeve 11. When the first pulling rope 9 and the second pulling rope 10 on the wire reel 7 are released, the first guide sleeve 8 and the second guide sleeve 11 can provide limiting and guiding functions, and the first guide sleeve 8 and the second guide sleeve 11 can prevent the first pulling rope 9 and the second pulling rope 10 from being worn.

[0024] As Figure 1 and Figure 5 shown, it further includes universal wheels 16, a cylinder 20 and a support block 21. Four universal wheels 16 are installed at the bottom of the robotic arm 1, the cylinder 20 is fixedly connected to the bottom of the robotic arm 1, and a support block 21 is fixedly connected to the piston rod of the cylinder 20, with the support block 21 close to the ground. The universal wheels 16 can facilitate the movement of this mounting bracket and can be moved to a designated position for installation through the universal wheels 16. When the door and window frame is heavy, the support block 21 is driven by the cylinder 20 to move downward and press the ground, which can increase the support area of this mounting frame and prevent this mounting frame from tipping due to the change of the center of gravity.

[0025] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes can be made therein without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
