Description
Technical Field
[0001] This utility model belongs to the technical field of pipe connectors, and in particular relates to an antistatic fluoroplastic pipe connector. Background Technology
[0002] Antistatic fluoroplastic pipes are special pipes designed to combine the excellent properties of fluoroplastics with antistatic functions. They are widely used in semiconductor, chemical, pharmaceutical, and energy fields to solve the safety hazards caused by static electricity accumulation in traditional fluoroplastic pipes. Fluoroplastics themselves have extremely low surface energy, excellent chemical corrosion resistance and high temperature resistance, but their high insulation makes them prone to static electricity accumulation. Antistatic fluoroplastic pipes upgrade their antistatic function through the embedding of conductive components and surface treatment technology.
[0003] In media transportation, it is often necessary to connect antistatic fluoroplastic pipes to combine disparate pipe segments into a continuous channel, ensuring media transmission and interconnection, and allowing the pipeline layout to adapt to complex operating conditions. However, in actual use, due to the varying spacing between adjacent antistatic fluoroplastic pipes, fixed-structure pipe connectors cannot meet the connection requirements between pipes with different spacing. Therefore, we provide an antistatic fluoroplastic pipe connector to solve the aforementioned technical problem. Utility Model Content
[0004] The purpose of this utility model is to provide an antistatic fluoroplastic pipe connector, which solves the problems in the background art by means of the specific structural design of the docking limiting component and the docking adjustment component.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is an antistatic fluoroplastic pipe connector, comprising two symmetrically arranged docking limiting components. Each docking limiting component includes a trapezoidal transmission ring that can move up and down and several symmetrically arranged trapezoidal transmission blocks. The lower surface of the trapezoidal transmission ring is an inclined sliding surface structure. The trapezoidal transmission ring and the trapezoidal transmission blocks are in sliding fit. A transmission cross column is fixedly connected to one side of each trapezoidal transmission block, and an arc-shaped limiting plate is fixedly connected to one end of the transmission cross column. A docking adjustment component is coaxially rotatably connected between the two docking limiting components. The docking adjustment component includes a rotatably arranged adjustment support tube. A telescopic adjustment tube is slidably arranged inside the adjustment support tube. The adjustment support tube is rotatably connected to one of the docking limiting components, and the telescopic adjustment tube is rotatably connected to the other docking limiting component.
[0006] The present invention is further configured such that the docking limiting component also includes a docking limiting platform, the docking limiting platform having an annular adjustment groove inside, and a plurality of lifting slides having a plurality of lifting slides on the surface of the docking limiting platform, the lifting slides being connected to the annular adjustment groove; the surface of the docking limiting platform having an internal threaded adjustment port, the adjustment port having an internal threaded engagement with a docking driving platform, the docking driving platform being composed of an external threaded tube that is threadedly engaged with the threaded adjustment port and a driving ring fixedly connected to the upper surface of the external threaded tube.
[0007] The present invention is further configured such that: the trapezoidal transmission ring is slidably disposed inside the annular control groove; a lifting transmission column is slidably disposed inside the lifting slide; one end of the lifting transmission column is in contact with the lower surface of the driving ring; and the other end of the lifting transmission column is fixedly connected to the trapezoidal transmission ring; a lifting return spring corresponding to each lifting transmission column is fixedly connected between the trapezoidal transmission ring and the top of the annular control groove; the lifting return spring is sleeved on the outside of the corresponding lifting transmission column; the trapezoidal transmission block is disposed inside the annular control groove; the transmission cross column slides through the docking limiting platform; a docking return spring is fixedly connected between the arc-shaped limiting plate and the docking limiting platform; and the docking return spring is sleeved on the outside of the corresponding transmission cross column.
[0008] The present invention is further configured such that an adjustment ring is fixedly connected to the upper surface of the adjustment support tube, the adjustment ring is coaxially rotatably connected to the docking limiting platform of one of the docking limiting components, a telescopic adjustment groove is provided inside the adjustment support tube, and an adjustment spiral groove is provided on one inner side wall of the telescopic adjustment groove; the telescopic adjustment tube is coaxially rotatably connected to the docking limiting platform of another docking limiting component, and an adjustment transmission column is fixedly connected to the peripheral side of the telescopic adjustment tube, the adjustment transmission column and the adjustment spiral groove are slidably engaged.
[0009] This utility model has the following beneficial effects: 1. By setting a docking limiting component, the rotating drive ring drives the external threaded pipe to rotate. Under the threaded cooperation of the external threaded pipe rotation and the internal thread adjustment port, the docking drive table moves towards the docking limiting table. The lifting transmission column is squeezed and drives the trapezoidal transmission ring to slide. Under the sliding cooperation of the trapezoidal transmission ring and the trapezoidal transmission block, the trapezoidal transmission block drives the arc-shaped limiting plate to move towards the axis until the position of the plastic pipe is limited. This achieves the connection limitation between the two plastic pipes and avoids leakage caused by deviation during use.

This utility model, by setting up a docking adjustment component, rotates the control ring to drive the adjustment support tube to rotate synchronously, and the control spiral groove rotates synchronously with the adjustment support tube. Under the sliding cooperation between the control spiral groove and the control transmission column, the control transmission column drives the telescopic adjustment tube to slide along the inner wall of the adjustment support tube, thereby realizing the telescopic operation of the docking adjustment component, and thus adjusting the distance between the two docking limit components, which facilitates the connection of plastic pipes of different distances and improves the applicability of the device.

Detailed Implementation
[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1 Please see Figure 1-6 This utility model is an antistatic fluoroplastic pipe connector, including two symmetrically arranged docking limiting components 1. Specifically, the docking limiting component 1 includes a trapezoidal transmission ring 101 that can move up and down and several trapezoidal transmission blocks 102 that are symmetrically arranged. The lower surface of the trapezoidal transmission ring 101 is an inclined sliding surface structure. The trapezoidal transmission ring 101 and the trapezoidal transmission blocks 102 are slidably engaged. A transmission cross column is fixedly connected to one side of the trapezoidal transmission block 102. An arc-shaped limiting plate 103 is fixedly connected to one end of the transmission cross column. The clamping surface of the arc-shaped limiting plate 103 is made of an elastic material structure, which facilitates the position limitation of the plastic pipe.
[0021] Furthermore, a docking adjustment component 2 is rotatably connected coaxially between the two docking limiting components 1. The distance between the two docking limiting components 1 is adjusted by the docking adjustment component 2 to facilitate the connection between the two plastic pipes. The docking adjustment component 2 includes a rotatably disposed adjustment support tube 201, and a telescopic adjustment tube 202 is slidably disposed inside the adjustment support tube 201. The adjustment support tube 201 is rotatably connected to one of the docking limiting components 1, and the telescopic adjustment tube 202 is rotatably connected to the other docking limiting component 1.
[0022] The operation process of this embodiment is as follows: According to the distance between the two plastic pipes to be connected, the telescopic length of the connection adjustment component 2 is adjusted, the adjustment support tube 201 is controlled to rotate, the telescopic adjustment tube 202 slides along the inner wall of the adjustment support tube 201, the connection adjustment component 2 performs telescopic operation, and thus adjusts the distance between the two connection limiting components 1. When connecting the two plastic pipes, one end of each plastic pipe is inserted into the corresponding connection limiting component 1, and the trapezoidal transmission ring 101 is controlled to move up and down. Under the sliding cooperation between the trapezoidal transmission ring 101 and the trapezoidal transmission block 102, the trapezoidal transmission block 102 moves towards the direction closer to the axis. Under the connection of the transmission cross column, the arc-shaped limiting plate 103 moves radially towards the direction closer to the axis until the arc-shaped limiting plate 103 is in close contact with the circumferential side of the plastic pipe, thereby realizing the connection between the two plastic pipes. Specific Implementation Example 2 Please see Figure 1-6Based on the specific embodiment 1, specifically, the docking limiting component 1 also includes a docking limiting platform 104. The docking limiting platform 104 has an annular adjustment groove 105 inside, and a plurality of lifting slides are formed on the surface of the docking limiting platform 104. The lifting slides are connected to the annular adjustment groove 105. The surface of the docking limiting platform 104 has an internal threaded adjustment port, and the internal thread of the adjustment port is engaged with a docking drive platform 106. The inner diameter of the docking drive platform 106 is adapted to the diameter of the pipe to be docked, so as to avoid leakage of the transported medium during the pipeline transportation process. At the same time, after the plastic pipe is docked, the intersection of the docking drive platform 106 and the pipe can be wrapped and sealed. The docking drive platform 106 consists of an external threaded pipe that is threaded with the threaded adjustment port and a drive ring fixedly connected to the upper surface of the external threaded pipe. The circumferential side of the drive ring has a rough material structure to facilitate the rotation of the external threaded pipe by the drive ring.
[0024] Furthermore, the trapezoidal transmission ring 101 is slidably disposed inside the annular control groove 105, and a lifting transmission column 107 is slidably disposed inside the lifting slide. One end of the lifting transmission column 107 is in contact with the lower surface of the drive ring, and the other end of the lifting transmission column 107 is fixedly connected to the trapezoidal transmission ring 101. A lifting return spring corresponding to the lifting transmission column 107 is fixedly connected between the trapezoidal transmission ring 101 and the top of the annular control groove 105, and the lifting return spring is sleeved on the outside of the corresponding lifting transmission column 107. The trapezoidal transmission block 102 is disposed inside the annular control groove 105, and the transmission cross column slides through the docking limit platform 104. A docking return spring is fixedly connected between the arc-shaped limit plate 103 and the docking limit platform 104, and the docking return spring is sleeved on the outside of the corresponding transmission cross column.
[0025] Furthermore, an adjustment ring 203 is fixedly connected to the upper surface of the adjustment support tube 201. The adjustment ring 203 is coaxially rotatably connected to the docking limiting platform 104 of one of the docking limiting components 1. An extension adjustment groove is provided inside the adjustment support tube 201, and an adjustment spiral groove 204 is provided on the inner side wall of the extension adjustment groove. The extension adjustment tube 202 is coaxially rotatably connected to the docking limiting platform 104 of the other docking limiting component 1. An adjustment transmission column 205 is fixedly connected to the periphery of the extension adjustment tube 202, and the adjustment transmission column 205 slides in conjunction with the adjustment spiral groove 204.
[0026] The operation process in this embodiment is as follows: Adjust the extension length of the docking adjustment component 2 according to the distance between the two plastic pipes to be docked. The specific operation is as follows: Rotating the control ring 203 causes the adjustment support tube 201 to rotate synchronously. The control spiral groove 204 rotates synchronously with the adjustment support tube 201. Under the sliding cooperation between the control spiral groove 204 and the control transmission column 205, the control transmission column 205 drives the telescopic adjustment tube 202 to move. The telescopic adjustment tube 202 slides along the inner wall of the adjustment support tube 201 to perform telescopic operation, thereby adjusting the distance between the two docking limit components 1.
[0027] When connecting two plastic pipes, one end of each pipe is inserted into the corresponding docking limiting platform 104. By rotating the drive ring, the external threaded pipe rotates. Under the threaded engagement of the external threaded pipe and the internal thread adjustment port, the docking drive platform 106 moves closer to the docking limiting platform 104, driving the ring to press the lifting transmission column 107. This causes the lifting transmission column 107 to drive the trapezoidal transmission ring 101 to slide up and down. Under the sliding engagement of the trapezoidal transmission ring 101 and the trapezoidal transmission block 102, the trapezoidal transmission block 102 moves closer to the axis. Under the connecting action of the transmission cross column, the arc-shaped limiting plate 103 moves radially closer to the axis until the arc-shaped limiting plate 103 is in close contact with the circumferential side of the plastic pipe, thus achieving the connection between the two plastic pipes.
