Description

Technical Field

[0001] This application relates to the field of riser fixing technology, and in particular to a pipe clamp for installing risers. Background Technology

[0002] Currently, the standard practice for installing risers is to drill holes in the wall and use expansion bolts for fixing.

[0003] The existing technical solutions mentioned above have the following drawbacks: the use of expansion bolts to fix the riser is fine when applied to load-bearing walls, but it is not reliable when used on non-load-bearing walls. In the current environment that advocates green and environmentally friendly construction, the walls are usually constructed in two ways, and the expansion bolts will damage the wall and are very easy to fall off. Utility Model Content

[0004] This application provides a pipe clamp for installing risers in order to ensure stable installation of risers.

[0005] The above-mentioned technical objective of this application is achieved through the following technical solution:

[0006] A pipe clamp for installing risers includes a first retaining ring, a connecting screw, and a mounting plate. The first retaining ring is a curved strip plate with a semi-circular sidewall. Both the outer peripheral wall of the first retaining ring and the surface of the mounting plate are provided with connectors. The axis of the connector is perpendicular to the surface of the mounting plate. The two ends of the connecting screw are threadedly connected to the connectors on the outer peripheral wall of the first retaining ring and the connectors on the surface of the mounting plate, respectively. A fixing nut is provided on the peripheral wall of the connecting screw, and the fixing nut is threadedly connected to the connecting screw.

[0007] By adopting the above technical solution, and by setting a first retaining ring, a connecting screw, an mounting plate, a connector, and a fixing nut, the first retaining ring and the mounting plate can be connected by the cooperation of the connecting screw and the two connectors. When installing the pipe clamp, a through hole is opened in the vertical wall, the mounting plate is placed on one side of the vertical wall, one end of the connecting screw is threaded to the connector on the outer peripheral wall of the first retaining ring, and the other end of the connecting screw is threaded into the through hole in the vertical wall and threaded to the connector on the surface of the mounting plate, thereby installing the pipe clamp on the vertical wall. This method is more stable than using expansion bolts to fix the pipe clamp.

[0008] Optionally, the pipe clamp also includes a second retaining ring, which is a semi-circular strip plate with a semi-annular sidewall. The two end faces of the first retaining ring and the two end faces of the second retaining ring abut against each other to form a complete ring. The ring formed by the first retaining ring and the second retaining ring is adapted to the outer peripheral wall of the riser. One end of the outer wall of the first retaining ring is provided with a first connecting end that is inclined toward the second retaining ring, and the outer wall of the end of the second retaining ring on the same side is provided with a second connecting end that is inclined toward the first retaining ring. The plate surface of the second connecting end is provided with a rectangular connecting hole that connects the two plate surfaces of the second connecting end. The first connecting end is adapted to the connecting hole and can be inserted into the connecting hole. The ends of the two side walls of the first connecting end away from the first retaining ring are provided with widening portions. The distance between the two widening portions and the side walls is less than the length of the connecting hole and greater than the width of the connecting hole, thereby locking the ends of the first retaining ring and the second retaining ring on the same side together.

[0009] By adopting the above technical solution, and by setting a second retaining ring, a first connecting end, a second connecting end, a connecting hole, and a widening part, the two end faces of the second retaining ring and the first retaining ring abut against each other to form a complete ring that fits the outer peripheral wall of the riser, thus clamping and fixing the riser. The first connecting end is inclined toward the second retaining ring, and the second connecting end is inclined toward the first retaining ring. The connecting hole is opened on the plate surface of the second connecting end and fits the first connecting end. The widening part is located on both sides of the end of the first connecting end away from the first retaining ring. The distance between the two widening parts and the side wall is less than the length of the connecting hole and greater than the width of the connecting hole. This allows the first retaining ring and the second retaining ring to be assembled into a complete clamping structure by snapping, which fits tightly against the outer peripheral wall of the riser, achieving stable clamping of the riser, and is also easy to disassemble and assemble.

[0010] Optionally, the outer wall end of the first retaining ring away from the first connecting end is provided with a first connecting plate, and the outer wall end of the second retaining ring away from the second connecting end is provided with a second connecting plate. The opposing surfaces of the first connecting plate and the second connecting plate can fit together. A notch is opened on the side wall of the second connecting plate, and a fixing bolt is provided in the notch. The end of the fixing bolt passes through the first connecting plate and is threadedly connected to the first connecting plate. The head of the fixing bolt is located on the side of the second connecting plate away from the first connecting plate.

[0011] By adopting the above technical solution, and by setting a first connecting plate, a second connecting plate, a notch, and a fixing bolt, the fixing bolt can tighten the connection between the first and second retaining rings, thereby improving the stability of the first and second retaining rings in clamping and fixing the riser. The notch design allows for disassembly and assembly without unscrewing the fixing bolts, reducing the possibility of bolt loss.

[0012] Optionally, an anti-loosening washer is provided between the head of the fixing bolt and the second connecting plate. The anti-loosening washer is a bendable metal strip plate. One end of the anti-loosening washer has an integrally formed protrusion on its side wall. The end of the anti-loosening washer with the protrusion has a circular through hole. The fixing bolt passes through the through hole on the anti-loosening washer and then through the notch and the first connecting plate. The fixing bolt is a hexagonal bolt.

[0013] By adopting the above technical solution, and by setting anti-loosening washers, after the riser is clamped and fixed, the end of the anti-loosening washer away from the through hole is bent towards the fixing plate, so that one side of the anti-loosening washer is in contact with the end face of the fixing plate. The protruding part of the anti-loosening washer is bent away from the second connecting plate, so that the surface of the protruding part is in contact with the hexagonal side wall of the fixing bolt. The anti-loosening washers can reduce the possibility of the fixing bolt loosening after long-term use.

[0014] Optionally, a fastening nut is provided on the side of the fixing nut away from the mounting plate, and the fastening nut is sleeved on the peripheral wall of the connecting screw and threadedly connected to the fastening nut.

[0015] By adopting the above technical solution and setting a fastening nut, a double locking structure can be formed in conjunction with the fixing nut, which strengthens the position of the fixing nut on the connecting screw and improves the stability of the connection between the connecting screw and the mounting plate and the first retaining ring.

[0016] Optionally, an annular fixing washer is provided between the fixing nut and the mounting plate, and the fixing washer is sleeved on the peripheral wall of the connecting screw.

[0017] By adopting the above technical solution and setting a fixing shim, the contact area between the fixing nut and the wall can be increased, the pressure of the fixing nut on the wall can be distributed, and the clamping of the fixing nut on the wall can be made more stable.

[0018] Optionally, the corner of the second connecting plate at the notch opening is chamfered.

[0019] By adopting the above technical solution, the corners of the second connecting plate at the notch opening are chamfered, which can guide the fixing bolts to be smoothly inserted into the notch, reduce the collision between the bolts and the connecting plate during installation, and improve the installation efficiency of the first and second retaining rings.

[0020] Optionally, both ends of the mounting plate are provided with waist-shaped threaded holes, and bolts can be inserted into the threaded holes to connect with the vertical wall via threads.

[0021] By adopting the above technical solution, and by setting a waist-shaped threaded hole, a bolt can be inserted into the threaded hole and connected to the vertical wall thread, which can form an additional fixed support for the mounting plate, restrict the movement space of the mounting plate, and reduce the occurrence of rotation after the pipe clamp is installed.

[0022] In summary, this application has the following technical effects:

[0023] 1. By setting up a first retaining ring, a connecting screw, a mounting plate, a connector, and a fixing nut, the first retaining ring and the mounting plate can be connected by the cooperation of the connecting screw and the two connectors. When installing the pipe clamp, a through hole is opened in the vertical wall, the mounting plate is placed on one side of the vertical wall, one end of the connecting screw is threaded to the connector on the outer peripheral wall of the first retaining ring, and the other end of the connecting screw is threaded through the through hole in the vertical wall and threaded to the connector on the surface of the mounting plate, thereby installing the pipe clamp on the vertical wall. This is more stable than using expansion bolts to fix the pipe clamp.

[0024] 2. By setting a second retaining ring, a first connecting end, a second connecting end, a connecting hole, and a widening part, the two end faces of the second retaining ring and the first retaining ring abut against each other to form a complete ring that fits the outer peripheral wall of the riser, thus clamping and fixing the riser. The first connecting end is inclined toward the second retaining ring, and the second connecting end is inclined toward the first retaining ring. The connecting hole is opened on the plate surface of the second connecting end and fits the first connecting end. The widening part is located on both sides of the end of the first connecting end away from the first retaining ring. The distance between the two widening parts and the side wall is less than the length of the connecting hole and greater than the width of the connecting hole. This allows the first retaining ring and the second retaining ring to be assembled into a complete clamping structure by snapping, which fits tightly against the outer peripheral wall of the riser, achieving stable clamping of the riser, and is also easy to disassemble and assemble.

[0025] 3. By setting anti-loosening washers, after the riser is clamped and fixed, the end of the anti-loosening washer away from the through hole is bent towards the fixing plate, so that one side of the anti-loosening washer is in contact with the end face of the fixing plate. The protruding part of the anti-loosening washer is bent away from the second connecting plate, so that the surface of the protruding part is in contact with the hexagonal side wall of the fixing bolt. The anti-loosening washers can reduce the possibility of the fixing bolt loosening after long-term use. Attached Figure Description
