Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of floor heating pipeline positioning, in particular to a U-shaped clamp for fixing floor heating pipelines. BACKGROUND

[0002] The U-shaped clamp is U-shaped and has a nail tip at the bottom, which can be directly nailed to the insulation layer and used for fixing the floor heating coil nail. More specifically, during the coil construction process, the U-shaped clamp nails the pipeline to the insulation board to prevent the pipeline from moving or popping up, ensuring that the pipeline is laid according to the required spacing and direction of the design drawing. It ensures that the adjacent pipelines maintain a uniform and constant spacing (usually 15 cm, 20 cm or 25 cm), and the uniform spacing is crucial for ensuring uniform heat dissipation and avoiding local overheating or overcooling in the entire heating area. When pouring is required, the U-shaped clamp firmly fixes the pipeline to the insulation board, effectively preventing the pipeline from shifting, floating or twisting during the pouring process, and ensuring that the pipeline is always in the designed position. The U-shaped clamp is easy and quick to install, and construction workers can directly use a nail gun or a hammer and other tools to nail it into the insulation board, greatly improving the stability of the laid floor heating coil. The U-shaped clamp can help fix the curved shape at the pipeline turning point, making the coil layout neat and beautiful.

[0019] The technical solutions in the embodiments of the present application will be described clearly and completely in the following with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all.

[0020] Referring to Figures 1-13 A U-shaped clamp for fixing radiant floor heating pipes, comprising an arc-shaped part 1, two extension parts 3 and two pin parts 2 connected together, more specifically, the two pin parts 2 are respectively located at the two bottom ends of the arc-shaped part 1, the two extension parts 3 are respectively inserted into the opposite positions of the two pin parts 2, and then the arc-shaped part 1, the extension parts 3 and the pin parts 2 are locked together by using a bolt screwed into the screwing hole 110 on the top of the arc-shaped part 1, the arc-shaped part 1, the two extension parts 3 and the two pin parts 2 are connected together by a screwing bolt 10, the bottom end of the screwing bolt 10 is provided with a transmission clamping groove 1010, the pin part 2 is provided with a rotating groove 210, a screwing groove 211 and a vertical displacement groove 220 in communication, and the pin part 2 is provided with an accommodation groove 222 on the surface, and the accommodation groove 222 and the vertical displacement groove 220 are provided with an avoiding opening 221 penetrating therebetween; A rotating rod 4 is rotatably provided in the rotating groove 210, and a rectangular transmission rod 410 is provided at the top of the rotating rod 4 and engages with the transmission slot 1010. There are also threads on a part of the rotating rod 4. The rotating rod 4 is provided with a detachable anti-detachment component. The number of detachable anti-detachment components is not limited to one. The detachable anti-detachment component includes a displacement sleeve 5, two anti-detachment blocks 6 and two linkage blocks 7. The displacement sleeve 5 is screwed onto the rotating rod 4 and is located in the threaded position. One anti-detachment block 6 is movably hinged to the displacement sleeve 5 through a linkage block 7. The connection position between the linkage block 7 and the anti-detachment block 6 is close to the top of the anti-detachment block 6. The bottom end of the anti-detachment block 6 is hinged to the bottom end of the receiving groove 222 on the pin part 2 through a rotating reset component. The rotating reset component includes a mounting part 8 and a reset member 9. The reset member 9 is installed inside the mounting part 8 and is connected to the anti-detachment block 6 through a rotating shaft 610.

[0021] Reference Figures 1-13 A U-shaped clip for fixing underfloor heating pipes, wherein a tightening groove 211 is provided from the top of the insertion part 2 and is connected to a rotating groove 210, and the inner wall of the tightening groove 211 has a thread that matches the bolt, and a vertical displacement groove 220 is provided in the rotating groove 210, and the diameter of the vertical displacement groove 220 is larger than that of the rotating groove 210, and the rotating groove 210, the tightening groove 211 and the vertical displacement groove 220 are on the same vertical axis; When the rotating rod 4 is installed inside the insert 2, the rectangular transmission rod 410 at the top of the rotating rod 4 is located in the tightening groove 211, and the threaded part of the rotating rod 4 is located in the vertical displacement groove 220. The blank part of the rotating rod 4 is rotatably connected to the rotating groove 210. When the tightening bolt 10 is turned downwards, the transmission slot 1010 at its bottom end approaches the top of the rectangular transmission rod 410. As the tightening bolt 10 is continued to be rotated, the transmission slot 1010 gradually fits onto the outside of the rectangular transmission rod 410 (the transmission slot 1010 is multi-stage). The rectangular slot allows the transmission slot 1010 to fit around the rectangular transmission rod 410 from different circumferential angles. At this time, the screw bolt 10 rotates, causing the rectangular transmission rod 410 to rotate. The rotation of the rectangular rotating rod 410 causes the rotating rod 4 to rotate clockwise. The rotation of the rotating rod 4 causes the displacement sleeve 5 to move upward through the thread (in this case, the anti-detachment block 6 is in the receiving groove 222 by default, and the two linkage blocks 7 are in between the two anti-detachment blocks 6 and one displacement sleeve 5). The displacement sleeve 5 is located slightly below the rotating rod 4. The rotating rod 4 rotates and drives the displacement sleeve 5 to move upward in the vertical displacement groove 220 through the thread. When the displacement sleeve 5 moves upward, it drives the linkage block 7 to move upward. The displacement sleeve 5 further expands the linkage block 7, and the linkage block 7 squeezes the upper part of the anti-detachment block 6 outward (at this time, the lower part of the anti-detachment block 6 rotates at the bottom end in the receiving groove 222), so that the anti-detachment block 6 and the plug part 2 form a certain angle, that is, the bottom end of the anti-detachment block 6 is connected to the plug part 2, and the top end of the anti-detachment block 6 is away from the plug part 2. The unfolded anti-detachment block 6 can prevent the plug part 2 from detaching from the insertion position. When the rotating rod 4 rotates counterclockwise, the rotating rod 4 is driven to rotate through the rectangular transmission rod 410. The rotating rod 4 drives the displacement sleeve 5 to move downward in the vertical displacement groove 220 through the thread. When the displacement sleeve 5 moves downward, it pulls the linkage block 7 downward. Furthermore, the linkage block 7 pulls the anti-detachment block 6 to rotate closer to the receiving groove 222. At the same time, with the assistance of the reset coil spring 920, the anti-detachment block 6 is completely closed in the receiving groove 222. After the anti-detachment block 6 is closed in the receiving groove 222, the side of the pin part 2 remains flat, so the pin part 2 can be pulled out upward without obstruction. When in use, the anti-detachment block 6 is placed in the receiving groove 222, and the side of the plug part 2 remains flat. The plug part 2 can be inserted into the insulation layer of the pipe, and then the anti-detachment block 6 is unfolded to limit and block it. In this way, the plug part 2 cannot be separated from the insulation layer and pulled out, and the arc-shaped part 1 presses on the pipe.

[0022] Reference Figures 1-13 A U-shaped clip for fixing underfloor heating pipes is provided. The displacement sleeve 5 is located in the vertical displacement groove 220, and a set of opposite faces of the displacement sleeve 5 are connected to the hinge block A. The linkage block 7 is located in the clearance opening 221, and both ends of the linkage block 7 are provided with hinge interfaces. The hinge block A of the displacement sleeve 5 is movably connected to the hinge interface at one end of the linkage block 7 through the hinge shaft. The anti-detachment block 6 matches the receiving groove 222, and the opposite face of the anti-detachment block 6 is provided with the hinge block B near the top. The hinge block B is movably connected to the hinge interface at the other end of the linkage block 7 through the hinge shaft. In this way, the displacement sleeve 5 and the two linkage blocks 7 can move together, and the linkage block 7 and the anti-detachment block 6 can move together. When the displacement sleeve 5 moves up and down in the vertical displacement groove 220, it can drive the linkage block 7 to move. The movement of the linkage block 7 can drive the anti-detachment block 6 to open or close.

[0023] Reference Figures 1-13A U-shaped clip for fixing underfloor heating pipes. A rotating shaft 610 is connected to an anti-detachment block 6 near its bottom end. A reset component 9 is sleeved on the outside of the rotating shaft 610. The reset component 9 includes a limiting ring 910, a reset coil spring 920, and a connecting ring 930. The reset coil spring 920 is connected between the limiting ring 910 and the connecting ring 930. The limiting ring 910, the reset coil spring 920, and the connecting ring 930 are sleeved on the rotating shaft 610, and are located in the mounting cavity 820. The connecting ring 930 is connected to the rotating shaft 610 by screws. On shaft 610, the connecting ring 930 and the rotating shaft 610 cannot rotate. The connecting ring 930 can also support the rotating shaft 610 and move within the mounting cavity 820. There is a movement gap between the limiting ring 910 and the return coil spring 920 and the rotating shaft 610, so that the limiting ring 910 and the return coil spring 920 can move within the rotating shaft 610. The limiting ring 910 can be installed inside the mounting cavity 820 and locked in the mounting cavity 820 from the outside of the bearing part 8 by screws, so that the limiting ring 910 cannot rotate within the mounting cavity 820.

[0024] Reference Figures 1-13 A U-shaped clip for fixing underfloor heating pipes is provided. The separate assembly and disassembly of the mounting part 8 and the reset part 9 facilitates the assembly of the components. A connecting block 810 is installed on the mounting part 8 by screws, and the connecting block 810 is connected to two corner positions at the bottom of the inner wall of the receiving groove 222 by screws. The mounting part 8 has an installation cavity 820, and the inner wall of the installation cavity 920 has a slot 821. The outer ring of the limiting ring 910 fixes the limiting block 911, and the limiting block 911 slides and engages with the slot 821. When the reset part 9 needs to be installed into the installation cavity 920, the limiting ring 910, the reset coil spring 920 and the connecting ring 930 are first put on the rotating shaft 610, and then the connecting ring 930 is locked on the rotating shaft 610 by screws. Then the limiting ring 910 on the rotating shaft 610 is rotated and the reset coil spring 920 is driven to rotate on the rotating shaft 610 to store force. When the reset coil spring 920 has accumulated sufficient force, the limiting ring 910 is not released. The limiting block 911 on the limiting ring 910 is aligned with the slot 821. Then, the limiting ring 910 and the limiting block 911 are slid into the mounting cavity 820 and the slot 821 simultaneously. In this way, the limiting ring 910 cannot rotate in the mounting cavity 820, so that the reset coil spring 920 remains in the stored state. When the anti-detachment block 6 is squeezed and rotated by external force, the rotating shaft 610 on the anti-detachment block 6 rotates and drives the reset coil spring 920 to rotate in the opposite direction of the stored force through the connecting ring 930. The top part of the anti-detachment block 6 rotates away from the receiving groove 222. When there is no external force, the reset force stored by the reset coil spring 920 drives the rotating shaft 610 to make the anti-detachment block 610 close in the receiving groove 222, which can assist the reset of the anti-detachment block 610.

[0025] Reference Figures 1-13A U-shaped clip for fixing underfloor heating pipes has a socket C311 and a socket D321 on the prong part 2. One end of the extension part 3 has a plug A310 and a plug B320. Plug A310 is inserted into the socket C311 and plug B321 is inserted into the socket D321. Plug B320 is locked in the socket D321 by a screw 10. This allows the extension part 3 and the prong part 2 to be connected together for use, and also makes it easy to separate the two.

[0026] Reference Figures 1-13 A U-shaped clip for fixing underfloor heating pipes, wherein both ends of the arc-shaped part 1 are provided with slots A120 and B130 that match the insert A310 and insert B320. When it is necessary to connect the extension part 3 with the arc-shaped part 1, insert A310 and insert B320 are inserted into slots A120 and slot B130, and then the bolt is screwed into the screw hole 120 to lock insert B320 in slot B130. In this way, the extension part 3 and the arc-shaped part 1 are used together. The bottom end of the extension section 3 is connected to an anti-detachment component 11, which includes an anti-detachment column and a fan-shaped anti-detachment part. The anti-detachment column is connected to the bottom end of the extension section 3, and the fan-shaped anti-detachment part is connected to the surface of the anti-detachment column. There are multiple fan-shaped anti-detachment parts distributed circumferentially on the surface of the anti-detachment column. When multiple fan-shaped anti-detachment parts are combined together in a circumferential distribution, they form a cone shape. When in use, the arc-shaped part 1 is connected to the extension section 3 with the anti-detachment component 11, so that it can be used without the plug part 2. Specifically, the arc-shaped part 1 is clipped onto the outside of the pipe, and the extension section 3 is located on both sides of the pipe. On the side, the anti-detachment component 11 is inserted into the insulation layer of the pipe. When the anti-detachment component is inserted downward, and the anti-detachment column is inserted into the insulation layer downward, multiple rubber fan-shaped anti-detachment parts are squeezed and stick to the surface of the anti-detachment column. When the anti-detachment column is fully inserted below the insulation layer, the multiple fan-shaped anti-detachment parts are not squeezed and reset and open under the action of elasticity. In this way, when the anti-detachment column is pulled upward, the multiple fan-shaped anti-detachment parts block the bottom of the insulation layer, making it impossible for the anti-detachment column to be pulled out. In this way, the extension part 3 and the arc-shaped part 1 cannot be separated from the insulation layer, and the pipe is restricted and positioned on the insulation layer.

[0027] The above embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.
