Description

Technical Field

[0001] This utility model relates to the field of double-hole pipe clamp technology, and in particular to an anti-slip double-hole pipe clamp. Background Technology

[0002] Double-hole pipe clamps are commonly used components in the field of pipe installation and fixing. They are widely used in various scenarios such as industrial production, building construction, and civil pipeline laying. They are mainly used to centrally fix two parallel pipes to ensure that the pipe layout is neat and to prevent the pipes from shifting due to external force collisions, medium flow vibrations, etc.

[0003] The core structure of most existing double-hole pipe clamps consists of a bottom clamp, a top clamp, and fastening bolts. Their working principle is generally that the fastening bolts pass through the top clamp and engage with the threaded hole on the bottom clamp. Tightening the bolts causes the top clamp to move closer to the bottom clamp, and the pipe is fixed by the vertical clamping force applied to the pipe by the top and bottom clamps.

[0004] Traditional double-hole pipe clamps rely solely on the vertical clamping force provided by the fastening bolts to secure the pipeline during actual use, lacking a dedicated anti-slip limiting structure. When the pipeline is exposed to vibration for a long time, or when the pipeline is transporting media and experiencing continuous impact, the fastening bolts are prone to loosening, causing the clamping force between the top and bottom clamps to gradually decrease. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an anti-slip double-hole pipe clamp.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a non-slip double-hole pipe clamp, comprising a bottom clamp and a top clamp, wherein the top clamp and the bottom clamp are arranged vertically and can be joined together to form a clamping space for accommodating pipes, and further comprising a fastening bolt and a threaded hole, wherein the threaded hole is opened on the upper end face of the bottom clamp along the vertical direction, and the fastening bolt extends vertically through the top clamp from the upper end face of the top clamp, with its threaded end extending downward and screwed into the threaded hole, wherein the pipe to be clamped is arranged in the clamping space between the top clamp and the bottom clamp, and the top clamp can be driven to move towards the bottom clamp in the vertical direction by tightening the fastening bolt, thereby clamping the pipe to be clamped, wherein the top clamp has a retaining tooth portion inside on the side facing the bottom clamp, which can extend from the inside of the top clamp into the clamping space and engage with the pipe to be clamped, so as to achieve anti-slip limiting of the pipe.

[0007] Preferably, the retaining tooth portion includes a sliding groove formed on the side of the top clamp along the horizontal direction of the top clamp. A pressing groove is provided below the sliding groove. The pressing groove extends upward from the clamping hole at the bottom of the top clamp and communicates with the sliding groove. A vertically arranged pressing piece is fixedly connected inside the sliding groove. The bottom end of the pressing piece extends downward and is fixedly connected with retaining teeth. A horizontally inserted rod is also inserted into the sliding groove. The end of the inserted rod facing the pressing piece has an inclined surface. In the assembled state, the inserted rod can slide inward along the horizontal direction of the sliding groove and press against the back of the pressing piece through the inclined surface of its end. This pushes the pressing piece to extend into the clamping hole along the vertical direction of the pressing groove, so that the retaining teeth on the surface of the pressing piece tightly abut against the pipeline, thereby achieving pipeline fixation and anti-slip.

[0008] Preferably, a horizontally arranged connecting plate is fixedly connected to the port of the insertion rod located outside the top clamp. The end of the connecting plate away from the insertion rod has a notch. A card adapted to the notch is rotatably connected to the outer surface of the top clamp. During assembly, pushing the connecting plate can cause the insertion rod to slide horizontally in the groove until the notch on the connecting plate passes through the card. At this time, the connecting plate is in contact with the outer surface of the top clamp. Rotating the card causes it to rotate horizontally to the outside of the connecting plate, blocking the connecting plate on the side away from the insertion rod, thereby preventing the insertion rod from being pulled out of the groove.

[0009] Preferably, the surface of the connecting plate is provided with a positioning hole, and a rubber positioning ball is fixedly connected to the side of the card facing the connecting plate. When the card rotates and passes over the surface of the connecting plate, the rubber positioning ball is deformed by the pressure of the connecting plate. When the card continues to rotate until the rubber positioning ball is aligned with the positioning hole, the rubber positioning ball elastically resets and is embedded in the positioning hole, thereby realizing the clamping and fixing of the card on the surface of the connecting plate.

[0010] Preferably, the upper end face of the bottom clamp is provided with a positioning hole in the vertical direction, and the bottom end face of the top clamp is provided with a downward protruding positioning pin at the position corresponding to the positioning hole. When the top clamp and the bottom clamp are assembled, the positioning pin is inserted into the positioning hole in the vertical direction and can slide along the axial direction of the positioning hole, thereby ensuring that the top clamp and the bottom clamp are accurately aligned and assembled.

[0011] Preferably, the bottom of the base clamp is provided with a horizontally arranged mounting plate. The surface of the mounting plate is provided with two long grooves, which are symmetrically arranged on both sides of the mounting plate along the central axis of the base clamp. The mounting plate is detachably assembled with the base clamp by bolts. In use, a clamp or binding strap can be passed through the long groove for fixation, and then the base clamp can be fixed to the surface of the column to be fixed by the clamp or binding strap, thereby realizing the fixation of the pipeline on the surface of the column.

[0012] Preferably, the assembly also includes an assembly groove, which is formed on the same end face of the bottom clamp and the top clamp. The inner wall of the assembly groove is provided with an inwardly recessed limiting groove. The assembly also includes a connecting block, which is fixed to the other end face of the bottom clamp and the top clamp. A triangular block is slidably inserted into the surface of the connecting block in the horizontal direction. A spring is fixedly connected between the triangular block and the connecting block. When the two sets of pipe clamps are assembled, the connecting block of one set of pipe clamps is inserted into the assembly groove of the other set of pipe clamps in the horizontal direction. During the insertion process, the connecting block squeezes the triangular block, causing the triangular block to compress the spring and retract into the connecting block. When the connecting block is fully inserted into the assembly groove, the spring elastically returns to its original position, pushing the triangular block outward and into the limiting groove, thereby fixing the assembly groove and the connecting block, and thus completing the combination and splicing of the two sets of bottom clamps and top clamps.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the inclined surface of the insert rod pushes the extrusion plate, causing the clamping teeth to tightly abut against the pipeline. Combined with the vertical clamping force of the top and bottom clamps from the fastening bolts, a double-fixing structure is formed, completely solving the problem of pipeline slippage and displacement caused by traditional pipe clamps relying solely on a single clamping force. The close-fitting and limiting action between the clamping teeth and the pipeline not only firmly fixes the pipeline but also adapts to pipelines of different outer diameters, effectively improving the stability of the pipe clamp during long-term use.

[0014] 2. In this utility model, the positioning hole at the upper end of the bottom clamp and the positioning pin at the bottom end of the top clamp are mutually compatible, which can quickly achieve precise alignment of the top clamp and the bottom clamp during assembly, avoid deviations during assembly, and reduce the difficulty of installation.

[0015] 3. In this utility model, the connecting plate, notch, and card at the end of the insertion rod are easy to operate. After pushing the insertion rod, rotating the card will complete the fixation. The engaging design of the rubber positioning ball and the positioning hole can also prevent the card from loosening. The entire assembly process does not require complicated tools, which greatly improves the efficiency of installation and disassembly.

[0016] 4. In this utility model, the mounting plate at the bottom of the clamp adopts a detachable design. Its two symmetrical elongated grooves can be adapted to different fixing components such as clamps and binding straps, enabling the pipe clamp to be securely installed on various carrier surfaces such as columns, breaking through the limitations of traditional pipe clamp installation scenarios. Furthermore, through the combination structure of the assembly groove, connecting block, and triangular block, multiple sets of pipe clamps can be quickly assembled, meeting both single-pipe fixing needs and adapting to scenarios with multiple pipes arranged in parallel, demonstrating extremely strong adaptability.

Detailed Implementation

[0019] Example 1, as Figure 1-4As shown, an anti-slip double-hole pipe clamp includes a bottom clamp and a top clamp. The top clamp and bottom clamp are arranged vertically to achieve a mating combination. The pipe clamp is also equipped with a fastening bolt and a threaded hole. The threaded hole is opened at the upper end of the bottom clamp. The fastening bolt passes through the top clamp from the upper end and continues through the top clamp. Its threaded end extends and engages with the threaded hole on the bottom clamp. A space is formed between the top clamp and the bottom clamp specifically for placing the pipe to be clamped. A retaining tooth is provided inside the top clamp on the side facing the bottom clamp. This retaining tooth can extend outward from the inside of the top clamp and engage with the pipe to be clamped, thereby preventing the pipe from slipping. The retaining tooth includes the part on the top clamp side. The top clamp has a sliding groove with an extrusion groove inside. The extrusion groove extends upward from the clamping hole at the bottom of the top clamp and is in communication with the sliding groove. An extrusion plate is fixedly installed inside the sliding groove, and a retaining tooth is fixedly connected to the bottom end of the extrusion plate, with the retaining tooth facing inward towards the clamping hole. A rod is also movably inserted inside the sliding groove. The end of the rod near the extrusion plate has an inclined surface that can fit against the back of the extrusion plate. A connecting plate is fixedly connected to the end of the rod outside the top clamp. A notch is formed at the end of the connecting plate away from the rod. A card is rotatably connected to the outer surface of the top clamp via a pivot. The size of the card is adapted to the notch. The connecting plate has positioning holes on its surface. A rubber positioning ball is fixedly connected to the side of the clip facing the connecting plate. The rubber positioning ball is made of highly elastic rubber, which can deform and return to its original position after compression. The upper end face of the bottom clamp has a positioning hole, and the bottom end face of the top clamp has a positioning pin at the corresponding position of the positioning hole. The outer diameter of the positioning pin matches the inner diameter of the positioning hole, ensuring that the positioning pin can be smoothly inserted into the positioning hole when the top clamp and bottom clamp are assembled. The bottom of the bottom clamp has a mounting plate with two elongated grooves on its surface. The two grooves are symmetrically distributed on both sides of the mounting plate with the central axis of the bottom clamp as the center of symmetry. The mounting plate is connected to the base clamp by bolts. This connection method allows the mounting plate to be easily removed from or installed on the base clamp. The pipe clamp is also equipped with an assembly groove, which is located on the same end face of the base clamp and the top clamp. A limit groove is provided on the inner wall of the assembly groove. The limit groove has an inwardly recessed structure. A connecting block is fixedly installed on the other end face of the base clamp and the top clamp. A triangular block is movably inserted into the surface of the connecting block. A spring is fixedly connected between the triangular block and the connecting block. The spring is always in a natural extension and contraction state. When the triangular block is squeezed, it will compress the spring and retract into the connecting block. After the squeezing force is released, the spring will drive the triangular block to return to its original position.

[0020] Working principle: When fixing the pipeline, first place the pipeline to be clamped in the clamping space between the bottom clamp and the top clamp. Then, insert the positioning pin at the bottom of the top clamp into the positioning hole at the top of the bottom clamp, ensuring precise alignment between the top and bottom clamps. Next, insert the fastening bolt through the top clamp and screw it into the threaded hole of the bottom clamp. Tighten the fastening bolt, driving the top clamp towards the bottom clamp, gradually clamping the pipeline to be clamped. Then, push the connecting plate, causing the insertion rod to slide in the groove. The insertion rod, through the inclined surface at its end, presses the back of the extrusion plate, causing the extrusion plate to extend into the clamping hole along the extrusion groove. The teeth at the bottom of the extrusion plate then come into close contact with the pipeline surface and abut tightly. Continue pushing the connecting plate until the notch on the connecting plate passes through the card on the surface of the top clamp. At this point, the connecting plate is in contact with the outer surface of the top clamp. Rotate the card. During the rotation of the card, the rubber positioning ball on the surface is subjected to... When the connecting plate is compressed and deformed, the rubber positioning ball aligns with the positioning hole when the card rotates. The rubber positioning ball then elastically resets and embeds itself into the positioning hole, fixing the card to the surface of the connecting plate. This restricts the retraction of the insertion rod and completes the anti-slip fixing of the pipeline. If it is necessary to fix the pipe clamp to the surface of the column, the bottom clamp can be fixed to the column using a clamp or strap through the long slot on the mounting plate. When multiple sets of pipe clamps need to be used together, the connecting block of one set of pipe clamps can be aligned with the assembly slot of another set of pipe clamps and inserted. During the insertion process, the connecting block compresses the triangular block, and the triangular block compresses the spring and retracts into the connecting block. When the connecting block is fully inserted into the assembly slot, the triangular block loses its compressive force, and the spring pushes the triangular block outward. The triangular block is then inserted into the limiting slot in the assembly slot, achieving the fixed splicing of the two sets of pipe clamps and meeting the need for simultaneous fixing of multiple pipelines.

[0021] Through holes can be made on the bottom clamp 1 and the top clamp 2 at the positions corresponding to the triangular block 19. The wire can be inserted along the through hole to press against the triangular block 19, so that the triangular block compresses the spring and retracts the connecting block 18 to pull out the assembly slot 14.
