Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary clamps, in particular to a right-angle joint auxiliary device for door and window frames. Background Art

[0002] Whether it is an aluminum alloy door and window frame or a wooden door and window frame, right-angled docking is evenly present. The two frames are perpendicular to each other and docked at one end. Generally, they are snapped together or riveted together. Of course, there are also methods of gluing or directly nailing them together.

[0003] Obviously, in most cases, the right-angle jointing of door and window frames needs to be done manually. In general, door and window frames are assembled into a rectangular shape, so the four frames need to be joined one by one. The existing method is to place the frame on a relatively flat ground, and then the four corners are aligned one by one, and the angles are measured, and finally fixed one by one.

[0004] However, this method has its drawbacks. When the operator fixes the first right angle, it is easy for other angles to move and become loose. When fixing, the measurement needs to be readjusted, which increases the labor intensity of the operator and affects the processing efficiency. When fixing the subsequent right angles, it may also cause the previous right angles to loosen, affecting the processing quality. Utility Model Content

[0021] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:

[0022] According to the instruction manual Figure 1-3It can be seen that in the present invention, the right-angled plates in the first right-angled plate 2 and the second right-angled plate 3 refer to two plates that are perpendicular to each other and are integrally formed, and hard alloy steel can be used here. During operation, the threaded rod 5 is driven to rotate by the driving member. Since the threaded rod 5 is screwed to the first slider 15 in the first chute 4, and the first slider 15 is slidably connected to the first chute 4, the rotation of the threaded rod 5 drives the first slider 15 to move, thereby driving the second right-angled plate 3 to move. The base plate 1 here is square, and its diagonal is 45 degrees. The first chute 4 is opened along the diagonal of the base plate 1 where the right-angle end of the first right-angled plate 2 is located, and the two sides of the second right-angled plate 3 are respectively parallel to the two sides of the second right-angled plate 3. Therefore, no matter how the second right-angled plate 3 moves, the distance between the two sides and the first right-angled plate 2 changes synchronously. The butt joint end of the door frame or window frame to be installed is placed between the first right-angled clamp 2 and the second right-angled clamp 3, and the driving member is started again to move the second right-angled clamp 3 toward the first right-angled clamp 2, thereby clamping the butt joint angle of the door frame or window frame. When the second right-angled clamp 3 moves, the second slider 13 is slidably connected to the second slide groove 14 on the end face of the base plate 1, the third slider 12 is slidably connected to the third right-angled clamp at the bottom of the second right-angled clamp 3, and the second slider 13 is fixedly connected to the second slider 13 by the connecting plate, so that the stability of the second right-angled clamp 3 during the movement can be guaranteed. Compared with the prior art, the present invention supports the butt joint end of the frame through the base plate 1, and clamps the butt joint end of the frame through the first right-angled clamp 2 and the second right-angled clamp 3, thereby ensuring its stability. Even when installing other angles or swinging and lifting, it will not easily loosen, has excellent stability, is convenient for personnel to work, and ensures the accuracy of the angle.

[0023] A rubber pad 9 is provided on the side wall between the first right-angled clamping plate 2 and the second right-angled clamping plate 3 to increase the friction between the door frame or window frame and improve the stability of its fixation.

[0024] Among them, scale marks 8 are set on the bottom plate 1, and they correspond to the two side plates of the second right-angle clamping plate 3 respectively. In this way, the opening distance between the second right-angle clamping plate 3 and the first right-angle clamping plate 2 can be observed. During installation, the distance between the second right-angle clamping plate 3 and the first right-angle clamping plate 2 can be appropriately opened according to the thickness of the frame, and the installation can be carried out quickly. At the same time, the thickness of the door frame can be checked to avoid installing the wrong frame.

[0025] The driving member adopts a stepper motor 6 to stably drive the threaded rod 5 to rotate. The stepper motor 6 is fixedly connected to the first right-angle clamping plate 2 through a mounting seat 7 to ensure the stability of the installation of the stepper motor 6.

[0026] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments 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.
