Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of architectural decoration, in particular to a door and window frame verticality calibration device. BACKGROUND

[0002] The installation quality of the door and window frame directly affects the opening flexibility, sealing performance and overall appearance of the door and window. At present, the most commonly used and basic tools for calibrating the verticality of the door and window frame at the construction site are two kinds: one is to use a plumb bob combined with a ruler to measure, that is, the construction personnel hold the plumb bob and let it naturally drop, then tightly attach the ruler to the side of the frame, and then judge the verticality by observing the deviation between the ruler and the plumb line; the other is to use high-tech electronic instruments such as laser level or electronic verticality detector, place the instrument near the frame, emit a vertical laser reference plane, and then measure the distance deviation between the side of the frame and the laser plane to determine the verticality.

[0003] However, the above-mentioned prior art cannot provide a stable and reliable force application fulcrum to assist the correction operation when the frame itself is not fixed in the actual application process. Specifically, when the frame is found to be not vertical, the construction personnel need to fine-tune it (such as tapping with a rubber hammer or using a crowbar), but neither the plumb bob nor the laser instrument provides a correction reference, but only a measurement reference. When adjusting the force, the construction personnel often need another person to observe the change of the measurement tool at the same time, or themselves repeatedly switch between the force application position and the observation position. This process is not only inefficient, but also difficult to accurately control the adjustment force and direction due to the lack of a force application reference connected with the measurement reference, which may easily cause "overcorrection" or insufficient adjustment, and needs to be repeated multiple times, affecting the installation efficiency and quality, especially when single person operation, the problem is particularly prominent. SUMMARY

[0040] In this embodiment: each of the plug-in plates 12 is provided with a threaded groove 13 distributed along the length direction, the movable plate body one 101 is provided with a positioning member 14 distributed at intervals, the positioning member 14 can be screwed down through the movable plate body one 101 into the threaded groove 13, the vacuum chuck 3, the digital level 2 and the support column 4 are each distributed one on the movable plate body one 101 and the movable plate body two 102, the vacuum chuck 3 is provided with an air pipe 15 penetrating upward through the bearing bottom plate 1, the other end of the air pipe 15 is connected with a vacuum pump body.

[0041] It should be noted that: the positioning member 14 adopts a bolt, the threaded groove 13 on the plug-in plate 12 cooperates with the positioning member 14 on the movable plate body one 101, by rotating the positioning member 14 to make it pass through the movable plate body one 101 downward and screw into the threaded groove 13, the relative position locking of the movable plate body one 101 and the movable plate body two 102 can be realized, preventing loosening during use, avoiding the length change of the bearing bottom plate 1.

[0043] In this embodiment: the bottom of the support column 4 is welded on the bearing bottom plate 1, the outer wall of the support column 4 is provided with a fixedly connected clamp 16, the outer wall of the clamp 16 is provided with a rotationally connected stabilizing rod 17 through a pin shaft, the stabilizing rod 17 is inclinedly arranged downward and rearward, the bottom of the stabilizing rod 17 is provided with an anti-skid disc 18 abutting against the ground.

[0044] It should be noted that: the support column 4 is fixed on the bearing bottom plate 1 by welding, the connection strength is high and can bear vertical load, the clamp 16 is welded on the outer wall of the support column 4, the stabilizing rod 17 is rotationally connected with the clamp 16 through a pin shaft, so that the stabilizing rod 17 can be adjusted in angle; the stabilizing rod 17 is inclinedly arranged downward and rearward, forming a triangular support structure, the anti-skid disc 18 abutting against the ground increases the friction.

[0045] The beneficial effects are that: welding ensures the integration of the support column 4 and the bearing bottom plate 1, preventing shaking, the stabilizing rod 17 can be retracted for transportation, after unfolding, the overall anti-overturning capacity is enhanced, the anti-skid disc 18 prevents slipping, especially suitable for smooth ground, improving the construction safety, at the same time, effectively preventing the bearing bottom plate 1 from separating from the ground due to the backward force applied by the pneumatic member 8 during the window frame adjustment process, causing the whole device to tip over.

[0046] In this embodiment: the top of the support column 4 is provided with a baffle 19, the lifting ring 6 is movably connected to the support column 4, the lifting ring 6 is provided with through holes 20 distributed horizontally in the upper and lower directions, the positioning assembly includes a positioning rod 21, a locking member 22, a vertical plate 23 and a handle 24, the positioning rod 21 is fixed vertically on the vertical plate 23 and can pass through the through hole 20 and the positioning hole 5 at the same time, the length of the positioning rod 21 is greater than the diameter of the lifting ring 6, the end of the positioning rod 21 that passes through the through hole 20 is provided with a threaded part, the locking member 22 cooperates with the threaded part, and the handle 24 is installed on the side of the vertical plate 23 away from the lifting ring 6.

[0047] It should be noted that: the baffle 19 prevents the lifting ring 6 from coming off the top of the support column 4, improving safety; the lifting ring 6 is aligned with the positioning hole 5 on the support column 4 through the through hole 20, and the positioning rod 21 passes through both to achieve height fixation; the threaded part and the locking part 22 (such as a nut) cooperate, and after tightening, the lifting ring 6 is pressed to prevent displacement; the handle 24 allows the operator to quickly pull out or insert the positioning rod 21, thereby realizing the quick positioning and locking of the lifting ring 6, adapting to door and window frames of different heights; the locking part 22 provides double insurance to ensure that the lifting ring 6 remains stable in a vibration environment.

[0048] In this embodiment: the mounting plate 7 is fixed on the outer wall of the two vertically distributed lifting rings 6. The two mounting plates 7 are symmetrical from left to right and have an "I"-shaped vertical cross section. One of the mounting plates 7 has guide grooves 25 on the upper and lower horizontal side walls, and the other mounting plate 7 has guide rods 26 on the horizontal side walls. The guide rods 26 are movably inserted into the guide grooves 25. Each mounting plate 7 also has a rotatingly connected stabilizing rod 17 installed on its back. The bottom of the stabilizing rod 17 is also equipped with an anti-slip disc 18.

[0049] It should be noted that the mounting plate 7 uses an "I"-shaped cross-section design to reduce weight while ensuring structural strength. The cooperation between the guide rod 26 and the guide groove 25 allows the left and right mounting plates 7 to move synchronously towards or away from each other, ensuring that they are always parallel and avoiding uneven stress on the window frame. The stabilizing rod 17 on the back of the mounting plate 7 is similar to the stabilizing rod 17 on the support column 4 and can be unfolded to form additional support points.

[0050] The beneficial effects are as follows: the "I" shaped structure optimizes the rigidity to weight ratio, the guiding mechanism ensures the linearity and consistency of the movement of the mounting plate 7, improves calibration accuracy, and the back stabilizing rod 17 further enhances the overall stability of the device, making it suitable for uneven ground.

[0051] In this embodiment: the number of pneumatic elements 8 is four and they are distributed in a rectangular shape in the vertical space, the cylinder body of the pneumatic element 8 is fixedly connected to the back of the mounting plate 7, the piston rod of the pneumatic element 8 penetrates through one end of the mounting plate 7 and is provided with a fixedly connected containing part 27, the abutting ball 9 is rotatably embedded in the containing part 27, and the abutting ball 9 is exposed from the containing part 27.

[0052] It should be noted that: the four pneumatic elements 8 are distributed in a rectangular shape to form a uniform thrust surface, so that the window frame is balanced in the calibration process and local deformation is avoided, the cylinder body is fixed to the back of the mounting plate 7 to save space, the containing part 27 at the end of the piston rod contains the abutting ball 9 and allows it to rotate freely, and the abutting ball 9 is in point contact with the surface of the window frame.

[0053] The beneficial effects are that the rectangular distribution ensures that the window frame is uniformly stressed up and down and left and right, improving the accuracy of the verticality calibration; the abutting ball 9 reduces friction and allows the window frame to adapt to angle changes during fine adjustment, preventing surface scratches; and the pneumatic element 8 has fast response speed, facilitating accurate control.

[0054] Further description is as follows: the rectangular arrangement of the pneumatic element 8 has the following schemes:

[0055] a scheme: when the verticality deviation of the window frame appears as up and down inclination, the pneumatic element 8 far from the window frame is first moved, and after abutting with the window frame, the pneumatic element 8 at the other height is moved, so that the abutting ball 9 gradually applies pressure to the window frame, driving the inclined end of the window frame to move backward, thereby gradually calibrating the verticality of the window frame.

[0056] b scheme: when the window frame appears as left and right inclination, the pneumatic element 8 distributed on the upper and lower sides is no longer moved, but is switched to the pneumatic element 8 distributed on the left and right sides, and the adjustment of the verticality is similar to the above-mentioned way, that is, when the pneumatic element 8 distributed on the left and right sides is closer to the window frame, the pneumatic element 8 distributed on the upper and lower sides on which side is first moved, and after the abutting ball 9 abuts with the window frame, the pneumatic element 8 on the other side is elongated, thereby gradually applying pressure to the window frame by the abutting ball 9, so that the window frame is parallel to the vertical space.

[0057] c scheme: when the verticality and left and right inclination of the window frame are calibrated, if there is a difference in the position where the window frame is installed, the four pneumatic elements 8 can be started at the same time, the abutting ball 9 at the end of the piston rod abuts with the window frame at the same time, thereby pushing the window frame as a whole to move to the appropriate position, facilitating the installation of the window frame.

[0058] By controlling the pneumatic element 8 at different positions to work, the window frame can be adjusted in multiple ways, ensuring the installation effect of the window frame.

[0059] In the embodiment, the lifting calibration assembly comprises a concave plate 28, a vertical screw rod 29, a lifting block 30 and a power element 31, the concave plate 28 is fixedly connected to the installation plate 7 near the window frame side, the "concave" of the concave plate 28 faces the window frame, the vertical screw rod 29 is vertically connected in the "concave" of the concave plate 28, the lifting block 30 is installed on the vertical screw rod 29 through a ball nut, the distance measuring sensor 10 is installed on the lifting block 30, and the power element 31 is externally connected to the power supply and installed on the top of the concave plate 28, and the output shaft of the power element 31 is connected with the vertical screw rod 29 through a shaft coupling.

[0060] It should be noted that the concave plate 28 provides a closed support structure, protects the internal components, and reduces the vibration influence, the vertical screw rod 29 cooperates with the ball nut to convert the rotary motion into linear motion and drive the lifting block 30 to move up and down, the power element 31 (such as a motor) directly drives the screw rod through the shaft coupling to realize the automatic lifting of the distance measuring sensor 10, the screw rod transmission has high precision, the distance measuring sensor 10 can be stopped at any height, multi-point measurement is realized, manual operation is reduced, efficiency is improved, and error is reduced.
