Description

A stainless steel connector Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a stainless steel connector. Background Technology

[0002] Connectors are components or devices used to connect two or more objects to form a whole structure. Stainless steel pipe connectors are components used to connect stainless steel pipes. They are used to fix stainless steel pipes together and form a complete pipeline system through various methods such as clamping, welding, and threaded connection.

[0003] Stainless steel pipe fittings are corrosion-resistant, high-strength, and reliably sealed, enabling them to securely connect pipes in various complex environments. They also offer advantages such as hygiene, environmental friendliness, easy installation, aesthetics, and durability, making them widely applicable in industries such as food and construction. However, traditional stainless steel fittings suffer from limitations in specifications, interfaces, environmental adaptability, and industry standards, resulting in insufficient versatility. Therefore, it is necessary to redesign a stainless steel fitting to address these issues. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a stainless steel connector.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A stainless steel connector includes two mounting frames. A support frame is fixedly mounted on the outer bottom wall of each mounting frame. A bidirectional screw is rotatably mounted inside each support frame. A motor connected to the bidirectional screw on the same side is fixedly mounted on the outer wall of each support frame. Limiting rods are fixedly mounted inside each support frame. Two moving blocks are rotatably mounted on the outer wall of each bidirectional screw via threads. The two limiting rods slide through the two moving blocks on the same side. A clamping block is fixedly connected to the outer wall of each moving block via a connecting mechanism. Each clamping block has a V-shaped inner wall. Hydraulic rods are fixedly mounted on both outer walls of one mounting frame via an mounting mechanism. A second mounting plate is fixedly mounted on the telescopic end of each hydraulic rod. Two connecting blocks are fixedly mounted on the outer wall of each second mounting plate. The two connecting blocks on the same side are fixedly connected to the outer wall of the other mounting frame via fixing bolts.

[0007] Preferably, the connecting mechanism includes a connecting rod fixedly installed on the upper surface of the movable block, the end of the connecting rod being fixedly connected to the outer wall of the clamping block, and the bottom wall of the mounting frame having a movable opening for cooperating with the movement of the connecting rod.

[0008] Preferably, the installation mechanism includes a first mounting plate fixedly installed on the outer wall of the mounting frame, and the hydraulic rod is fixedly installed on the outer wall of the first mounting plate.

[0009] Preferably, each of the clamping blocks has an anti-slip pad fixedly installed on its inner wall, and each anti-slip pad is made of chemically resistant nitrile rubber.

[0010] Preferably, a multi-way valve is fixedly installed on the outer wall of one of the mounting frames, and the multi-way valve is fixedly connected to the connection ports of two hydraulic rods through oil pipes.

[0011] The beneficial effects of this utility model are:

[0012] 1. By setting up components such as a bidirectional screw, motor, limit rod, moving block, and clamping block, the motor is started to drive the bidirectional screw to rotate. Under the restriction of the limit rod, the moving blocks can only move towards each other along the direction of the bidirectional screw. The moving blocks drive the clamping blocks to move closer to each other through the connecting rod, which can clamp stainless steel. The V-shaped opening and anti-slip pad on the inner wall of the moving block can effectively clamp stainless steel pipes of different sizes and shapes, so that different stainless steels can be connected, which has higher versatility.

[0013] 2. By setting up components such as hydraulic rods, second mounting plates, connecting blocks, and multi-way valves, two second mounting plates on the same side are fixedly connected to another mounting frame by fixing bolts. The hydraulic rods are synchronously controlled by the oil pipes of the multi-way valves. The retraction of the hydraulic rods can enable the stainless steel on both sides of the mounting frames to quickly connect and ensure the tightness of the pipe connection.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Referring to Figures 1-4, a stainless steel connector includes two mounting frames 1. Support frames 2 are fixedly mounted on the outer bottom walls of both mounting frames 1. Bidirectional screws 3 are rotatably mounted inside each support frame 2. Motors 4, connected to the bidirectional screws 3 on the same side, are fixedly mounted on the outer walls of both support frames 2. Limiting rods 5 are fixedly mounted inside each support frame 2. Two moving blocks 6 are rotatably mounted on the outer wall of each bidirectional screw 3 via threads. The two limiting rods 5 slide through the two moving blocks 6 on the same side. A clamping block 8 is fixedly connected to the outer wall of each moving block 6 via a connecting mechanism. The connecting mechanism includes a connecting rod 7 fixedly mounted on the upper surface of the moving block 6. The end of the connecting rod 7 is fixedly connected to the outer wall of the clamping block 8. The bottom wall of the mounting frame 1 has a moving opening to accommodate the movement of the connecting rod 7, ensuring smooth movement of the connecting rod 7. Each clamping block 8 has a V-shaped inner wall. This unique V-shaped structure allows for line contact when in contact with a circular stainless steel pipe. Compared to traditional planar clamping methods, the V-shaped structure can significantly increase the contact area, effectively improve the clamping force, and has good self-adaptability to pipes of different diameters. Each clamping block 8 has an anti-slip pad 9 fixedly installed on its inner wall. Each anti-slip pad 9 is made of chemically resistant nitrile rubber, and its surface has a high coefficient of friction, which can effectively prevent the stainless steel pipe from sliding during the clamping process.

[0021] Hydraulic rods 11 are fixedly mounted on both outer walls of one of the mounting frames 1 via a mounting mechanism. The mounting mechanism includes a first mounting plate 10 fixedly mounted on the outer wall of the mounting frame 1. The hydraulic rods 11 are fixedly mounted on the outer wall of the first mounting plate 10. Double-acting hydraulic rods 11 are selected, which have stable telescopic thrust output capability and precise stroke control accuracy, thus providing stable and controllable thrust during pipe connection. A second mounting plate 12 is fixedly mounted on the telescopic end of each hydraulic rod 11. The function of the second mounting plate 12 is to connect the two mounting frames 1 and evenly transmit the telescopic force of the hydraulic rods 11 to the entire connection structure. Two connecting blocks 13 are fixedly installed on the outer wall of each mounting plate 12. The two connecting blocks 13 on the same side are fixedly connected to the outer wall of another mounting frame 1 by fixing bolts. A multi-way valve 14 is fixedly installed on the outer wall of one of the mounting frames 1. The multi-way valve 14 is fixedly connected to the connection port of two hydraulic rods 11 through an oil pipe. Through the precise control of the multi-way valve 14, the synchronous drive and pressure adjustment of the two hydraulic rods 11 can be realized, ensuring that the stainless steel pipes on the two mounting frames 1 can be quickly and accurately connected, and ensuring that the pipe connection has good sealing and tightness, effectively preventing media leakage and meeting the usage requirements under various working conditions.

[0022] When using this utility model, two stainless steel pipes are placed in two mounting frames 1 respectively. The motor 4 installed on the outer wall of the support frame 2 is started. The motor 4 drives the bidirectional screw 3 inside the support frame 2 to rotate. Due to the special thread structure of the bidirectional screw 3, the two moving blocks 6 installed on its outer wall through the thread rotation move in opposite directions along the bidirectional screw 3 under the limiting action of the limiting rod 5. The moving blocks 6 drive the clamping blocks 8 to move synchronously through the connecting rod 7. As the clamping blocks 8 gradually approach, their V-shaped inner wall fits against the surface of the stainless steel pipe. The anti-slip pad 9 on the inner wall is in tight contact with the stainless steel pipe. Relying on the large friction force generated by the chemical corrosion resistant nitrile rubber material, the stainless steel pipe is firmly clamped.

[0023] When stainless steel pipes need to be connected, align the connecting block 13 on the second mounting plate 12 on the same side with the outer wall of the other mounting frame 1, and use fixing bolts to connect the connecting block 13 through the threaded hole and the corresponding hole on the mounting frame 1. Then, control the two hydraulic rods 11 to retract synchronously through the multi-way valve 14. The hydraulic rods 11 drive the stainless steel pipes on the two mounting frames 1 to slowly connect until the pipe joints are completely fitted, ensuring the tightness of the connection.

[0024] 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 the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
