Abstract
Description
Technical Field
[0001] The utility model relates to the field of pipeline installation, in particular to a bending device for installing corners of heating pipelines. Background Art
[0002] Heating pipes are an important part of the heating system and are responsible for transporting the heat energy generated by the heat source to various heating terminals. The working principle of the heating system is based on three methods of heat conduction, convection and radiation to achieve heat energy transfer. The system works together through boilers, circulation pumps, radiators and other accessories to transport heat to indoor spaces. Heating pipes can use a variety of materials, including cast iron, copper, stainless steel, PPR, PE pipes, etc., each with its own advantages and disadvantages, suitable for different usage scenarios.
[0003] Heating pipes are generally installed against the wall at the inlet position. When the heating pipes pass through the angle between two walls, in order to fix the heating pipes, it is usually necessary to drill holes on both walls at the same time and install fixing brackets to fix the pipes. However, since the drilling positions in different planes are difficult to determine, it is easy for the hole positions to shift without auxiliary tools. In addition, some pipes or walls are not completely right angles, and conventional pipe brackets cannot be bent. As a result, when installing the bent pipes, multiple brackets can only be used for fixing, which further increases the difficulty of fixing the heating pipes. Therefore, a bending device for installing the corners of heating pipes is proposed to solve the above problems. Utility Model Content

When the heating pipes pass through the angle between two walls, in order to fix the heating pipes, it is usually necessary to drill holes on both walls at the same time and install fixing brackets to fix the pipes. However, since the drilling positions in different planes are difficult to determine, it is easy for the hole positions to be offset without auxiliary tools. In addition, some pipes or walls are not completely right angles, and conventional pipe brackets cannot be bent. As a result, when installing the bent pipes, only multiple brackets can be used for fixation, which further increases the difficulty of fixing the heating pipes.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0027] In the embodiment, Figure 1-4A bending device for installing the corners of a heating pipe is provided. The utility model includes a first mounting plate 1, and the upper and lower sides of the first mounting plate 1 are fixedly connected to extension plates 2, and the interiors of the two extension plates 2 are provided with mounting holes. The outer side of the first mounting plate 1 is rotatably connected to the second mounting plate 3, and the outer sides of the first mounting plate 1 and the second mounting plate 3 are fixedly connected to limit frames 4. The outer sides of the first mounting plate 1 and the second mounting plate 3 are fixedly connected to limit devices 5 corresponding to the two limit frames 4 respectively, and the outer side of the first mounting plate 1 is rotatably connected to a connecting frame 6 that is slidably connected to the second mounting plate 3. The outer side of the connecting frame 6 is provided with two annular sleeves 7 that are symmetrically distributed up and down, and the outer sides of the two annular sleeves 7 are fixedly connected to threaded rods 8, and the outer sides of the two threaded rods 8 are threadedly connected to threaded sleeves 9.
[0028] Among them, the two limiting devices 5 include fixed plates 51 fixedly connected to the outer side of the first mounting plate 1 and the outer side of the second mounting plate 3 respectively, the interior of the two fixing plates 51 are threadedly connected with bolt knobs 52, the outer sides of the two bolt knobs 52 are rotatably connected with pressure plates 53, and the outer sides of the two pressure plates 53 are fixedly connected with telescopic rods 54 fixedly connected to the two fixing plates 51 respectively.
[0029] In this embodiment, during actual use, after the heating pipe is placed into the limit frame 4, the bolt knob 52 is turned to move the pressure plate 53. Under the restriction of the telescopic rod 54, the movement direction of the pressure plate 53 is restricted, and the movement of the pressure plate 53 can fix the heating pipe in the limit frame 4.
[0030] The limiting frame 4 is U-shaped, and the width of the pressing plate 53 is smaller than the inner width of the limiting frame 4 .
[0031] In this embodiment, during actual use, the U-shaped limit frame 4 can limit three sides of the heating pipe, and the pressure plate 53 can move and extend into the interior of the limit frame 4 to fix the heating pipe.
[0032] The second mounting plate 3 is provided with two sliding grooves symmetrically distributed in the upper and lower directions. The outer side of the connecting frame 6 is rotatably connected to two rollers 10 that are respectively slidably connected to the two sliding grooves.
[0033] In this embodiment, during actual use, when the first mounting plate 1 and the second mounting plate 3 rotate relative to each other, the roller 10 slides in the slide groove, and the roller 10 rotatably connected to the connecting frame 6 moves more smoothly in the slide groove.
[0034] A clearance groove is provided inside the second mounting plate 3 , the connecting frame 6 is U-shaped and passes through the clearance groove, and the two annular sleeves 7 are both slidably connected to the connecting frame 6 .
[0035] In this embodiment, during actual use, when the first mounting plate 1 and the second mounting plate 3 rotate relative to each other, the connecting frame 6 will undergo a certain angle change, and there is a certain gap between the annular sleeve 7 and the connecting frame 6. The rotation of the connecting frame 6 will not drive the annular sleeve 7 to rotate, and the movement of the connecting frame 6 between the second mounting plates will drive the annular sleeve 7 to move.
[0036] The two threaded rods 8 both pass through and extend to the outside of the second mounting plate 3 , and the lengths of the two threaded rods 8 are both greater than the maximum length of the clearance groove.
[0037] In this embodiment, during actual use, when the first mounting plate 1 and the second mounting plate 3 are rotated to a certain angle, the threaded rod 8 will extend into and out of the second mounting plate 3. At this time, the threaded rod 8 will always remain partially on the outside of the second mounting plate 3, and the connecting frame 6 can be fixed by fixing the threaded rod 8.
[0038] Working principle:
[0039] When installing and fixing the heating pipe, first fix the device to the wall through the mounting hole on the extension plate 2 with the bolt lamp fasteners, and then adjust the angle between the second mounting plate 3 and the first mounting plate 1 according to the bending degree of the heating pipe. At this time, it is necessary to unscrew the threaded sleeve 9. When the second mounting plate 3 is rotated, the connecting frame 6 and the first mounting plate 1 rotate, and the connecting frame 6 will slide inside the second mounting plate 3. The roller 10 stabilizes its sliding direction to prevent the connecting frame 6 from shaking and deviating in the give way groove. The movement of the connecting frame 6 will drive the annular sleeve 7 and the threaded rod 8 to move. After finding the appropriate angle, the threaded rod 8 can be fixed by the threaded connection between the threaded sleeve 9 and the threaded rod 8 to prevent the connecting frame 6 from moving, so that the second mounting plate 3 remains fixed. Then the bent heating pipe is placed into the two mounting plates, and the pressure plate 53 can be pressed into the limit frame 4 by turning the bolt knob 52 to fix it.
