Description

Technical Field

[0001] This utility model relates to the field of universal connector technology, and more specifically, to a French universal connector. Background Technology

[0002] A universal pipe connector is a flexible and adaptable connection device that can quickly connect pipes of different materials, specifications, or standards in different scenarios, reducing reliance on special connectors.

[0003] A French universal joint is a type of joint that combines a flange interface with multiple adaptation functions, retaining the high sealing performance of the flange while being compatible with different flange standards or quick connection requirements.

[0004] Existing French universal connectors typically only connect and secure one side of the pipe when connecting it to a pipeline, while the other side is only connected via a connecting rod and bolts. This results in a lack of securing means at the contact point between the pipe and the connector on the other side, making it prone to side leakage and damage. Cable ties are often required for additional securing, which is not conducive to its use. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide a French universal connector. The upper mating block is moved by the side fixing rod, and the V-shaped extension plate clamps and fixes the pipe in front. The middle adjusting cam and the rear insertion mating tube cooperate to clamp and fix the pipe in the rear. This provides a better fixing effect between the pipe and the connector, and it can also be adapted to more types of pipes. Its installation and disassembly are relatively convenient, will not damage the pipe, and is conducive to long-term use.

[0007] 2. Technical Solution

[0010] As a preferred embodiment of this utility model, the rear connector component includes: two side mounting seats, two center adjustment cams, two side fixing rods, and a rear insertion fitting tube. The two side mounting seats are fixedly connected to the outer walls of both sides of the side extension sleeve. The two center adjustment cams are rotatably connected between the inner walls of the corresponding side mounting seats. The two side fixing rods are fixedly connected to the outer wall of one side of the corresponding center adjustment cam. The rear insertion fitting tube extends and is disposed on the outer wall of one side of the front insertion connecting tube.

[0011] As a preferred embodiment of this utility model, the outer wall of the side extension sleeve has two mounting ports, and the two mounting ports respectively cooperate with the corresponding side mounting seats.

[0012] As a preferred embodiment of this utility model, two downward fixing rods are fixedly connected to one end of each of the two V-shaped extension plates.

[0013] As a preferred embodiment of this utility model, the two upper mating blocks respectively mate with the corresponding side fixing rods.

[0014] As a preferred embodiment of this utility model, a fixing hole is provided on one side of the outer wall of each of the two side fixing rods.

[0015] 3. Beneficial effects

[0016] Compared with the prior art, this utility model provides a French universal connector, which has the following advantages:

[0017] This connector employs a front and rear independent clamping structure. At the front, a sliding plate within the through-groove moves a V-shaped extension plate, which, along with a downward-pressing fixing rod, clamps and secures the inserted pipe from multiple sides. At the rear, side mounting seats on both sides of the side extension sleeve engage with adjusting cams, which, through a linkage with the side fixing rod, achieve clamping and positioning of the rear-inserted fitting pipe onto the rear pipe. The front and rear clamping mechanisms are independent yet can work collaboratively, allowing for balanced force application to both pipe sections during actual use. This enhances connection stability and vibration resistance, effectively avoiding side leakage, loosening, and damage problems caused by unilateral fixing in traditional French connectors.

[0018] In terms of installation structure, this connector incorporates a combination of a sliding plate and a V-shaped extension plate. Under the pressure of the side fixing rod, the upper mating block drives the sliding plate into the through groove. The V-shaped extension plate then opens to generate multi-directional clamping force, which, together with the lower fixing rod, acts on the pipe surface to achieve automated fitting and clamping. The entire process requires no external tools; the connector's own structure enables rapid and stable installation, greatly simplifying the construction process and improving work efficiency. Furthermore, this structure possesses a certain degree of self-adjustment, making it suitable for various pipes with slightly different outer diameters without causing insufficient clamping or pipe damage due to dimensional tolerances. This is of great value in practical engineering construction.

[0019] Furthermore, this device achieves true "non-destructive installation and disassembly" while maintaining connection strength. Through a closed outer sleeve protection structure and a linkage clamping mechanism, it eliminates the need for destructive methods such as bolt drilling and cable ties, and avoids thermal deformation and safety hazards caused by welding. This ensures that the pipeline will not be indented, cracked, or permanently deformed during repeated installation and maintenance, thus extending the overall service life of the pipeline and joints.

[0020] More importantly, due to its modular design, this connector allows for flexible replacement and adjustment of multiple internal components (such as the central adjusting cam, the rear insert fitting pipe, and the V-shaped extension plate). Its overall structure can adapt to various international piping standards (such as DIN, ANSI, and JIS) and connections between pipes of different materials (such as PVC, PE, and metal pipes), truly achieving a "universal" characteristic. This structural compatibility surpasses the limitations of conventional French-style connectors with a single interface, enabling its widespread application in complex and varied piping systems in building, municipal, fire protection, and industrial applications.

[0021] In summary, this utility model, through structural innovation, linkage control, and multi-directional adaptation, achieves three technical goals that traditional technologies cannot reach: multi-point stable clamping, non-destructive and rapid installation, and high-standard compatibility. It produces unexpected technical effects that are difficult for those skilled in the art to foresee, and has significant practicality and inventiveness. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0028] Example:

[0029] Please see Figure 1-3 A French universal connector includes: a front insertion connecting pipe 1, with a side extension outer sleeve 2 extending from the outer wall of the front insertion connecting pipe 1; and a connector assembly, the connector assembly including: a front extension outer sealing pipe 3, two front connector components and a rear connector component, the front extension outer sealing pipe 3 extending from one side of the outer wall of the side extension outer sleeve 2, the outer wall of the front extension outer sealing pipe 3 having two through grooves, each of the two front connector components including: a sliding plate 9, a V-shaped extension plate 10 and an upper mating block 11, the sliding plate 9 being slidably disposed in the through groove, the V-shaped extension plate 10 being fixedly connected to one end of the sliding plate 9, the upper mating block 11 being fixedly connected to one side of the outer wall of the V-shaped extension plate 10, and the rear connector component being disposed on one side of the side extension outer sleeve 2 for connecting pipes.

[0030] In a specific embodiment of this utility model, the pipe is inserted into the front of the connecting pipe 1, at which point the front extension outer sealing pipe 3 and the outer wall of the front pipe are engaged. Then, the rear pipe is inserted into the side extension outer sleeve 2, at which point the rear insertion fitting pipe 8 enters the rear pipe. Then, the side fixing rod 6 is rotated, so that one end of the two side fixing rods 6 moves to the front pipe and is fixed by bolts. At this time, the side fixing rod 6 will press the two upper fitting blocks 11, causing the sliding plate 9 and the V-shaped extension plate 10 to move. The V-shaped extension plate 10 and the lower pressing fixing rod 12 will engage with the front insertion connecting pipe 1 to clamp and fix the front pipe. When the side fixing rod 6 rotates, the middle adjusting cam 5 rotates and engages with the rear insertion fitting pipe 8 to clamp and fix the rear pipe. Multiple clamping and fixing results in a better fixing effect between the pipe and the joint. It can also adapt to more types of pipes. Its installation and disassembly are relatively convenient, and it will not damage the pipe, which is conducive to long-term use.

[0031] Specifically, the rear connector component includes: two side mounting seats 4, two center adjustment cams 5, two side fixing rods 6, and a rear insertion fitting tube 8. The two side mounting seats 4 are fixedly connected to the outer walls of both sides of the side extension sleeve 2. The two center adjustment cams 5 are rotatably connected between the inner walls of the corresponding side mounting seats 4. The two side fixing rods 6 are fixedly connected to the outer wall of one side of the corresponding center adjustment cam 5. The rear insertion fitting tube 8 extends and is disposed on the outer wall of one side of the front insertion connecting tube 1.

[0032] In this embodiment, a central adjustment cam 5 is set on the side mounting base 4. The central adjustment cam 5 rotates to clamp and fix the pipe. The rotating central adjustment cam 5 will drive the side fixing rod 6 to rotate, thereby making adjustment. Then, the fitting tube 8 is inserted to cooperate with the central adjustment cam 5, thereby fixing the pipe and improving the sealing effect.

[0033] Specifically, the outer wall of the side extension sleeve 2 has two mounting ports, which are respectively matched with the corresponding side mounting seats 4.

[0034] In this embodiment, a side mounting seat 4 is provided through the mounting port, which also enables the center adjustment cam 5 to work.

[0035] Specifically, two downward fixing rods 12 are fixedly connected to one end of each of the two V-shaped extension plates 10.

[0036] In this embodiment, the downward pressing and fixing effect of the V-shaped extension plate 10 is improved by pressing down the fixing rod 12, thereby enhancing the fixing effect.

[0037] Specifically, the two upper mating blocks 11 respectively mate with the corresponding side fixing rods 6.

[0038] In this embodiment, the overall fixing operation is performed by pressing down the upper mating block 11 with the side fixing rod 6.

[0039] Specifically, fixing holes 7 are provided on one side of the outer wall of both side fixing rods 6.

[0040] In this embodiment, the side fixing rod 6 is fixed through the fixing hole 7.

[0041] Working principle: The pipe is inserted into the front of the connecting pipe 1, where the front extension outer sealing pipe 3 engages with the outer wall of the front pipe. Then, the rear pipe is inserted into the side extension outer sleeve 2, where the rear insertion fitting pipe 8 enters the rear pipe. The side fixing rods 6 are then rotated, moving one end of each rod to the front pipe and securing it with bolts. The side fixing rods 6 then press against the two upper fitting blocks 11, causing the sliding plate 9 and V-shaped extension plate 10 to move. The V-shaped extension plate 10 and the lower pressing fixing rod 12 engage with the front insertion connecting pipe 1 to clamp and fix the front pipe. When the side fixing rods 6 rotate, the middle adjusting cam 5 rotates and engages with the rear insertion fitting pipe 8 to clamp and fix the rear pipe. This repeated clamping and fixing provides better fixation between the pipe and the connector, and it can also accommodate more types of pipes. Installation and disassembly are convenient and will not damage the pipe, making it suitable for long-term use.

[0042] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
