Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of sealing gaskets, specifically a convenient-installation polytetrafluoroethylene gasket. Background Technology
[0002] Gaskets can be broadly categorized into non-metallic gaskets, metallic gaskets, and metal-non-metal composite gaskets based on their materials and structural characteristics. Each category can be further subdivided into several types. Polytetrafluoroethylene (PTFE) gaskets (commonly known as "the king of plastics") are characterized by their resistance to acids and alkalis, high temperatures, and various organic solvents. They are widely used in the chemical and pharmaceutical industries and are considered the originator of gaskets.
[0003] Existing PTFE composite gaskets have the following drawbacks when used: the gasket has a ring-shaped structure, which is inconvenient to handle and can easily cause the gasket to shift, reducing the sealing performance at the installation point and affecting installation efficiency. Utility Model Content
[0004] The purpose of this invention is to provide a convenient-installation polytetrafluoroethylene gasket to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable polytetrafluoroethylene gasket, comprising an inner gasket, an outer gasket, and a metal plate connecting the inner and outer gaskets. The inner gasket has a central hole at its center. The metal plate is positioned between the inner and outer gaskets and is fixedly connected to both gaskets. Annular grooves are formed on both sides of the metal plate. Multiple mounting slots are evenly distributed within these annular grooves. An auxiliary mounting structure is provided within each mounting slot. This auxiliary mounting structure includes a rotating rod and a connecting rod. The rotating rod is entirely positioned within the mounting slot. The connecting rod is fixedly disposed on the outer side of the middle portion of the rotating rod, and the other end of the connecting rod is rotatably connected to the inner wall of the mounting slot.
[0006] Preferably, the length of the rotating rod is greater than the thickness of the metal plate and less than the length of the mounting groove.
[0007] Preferably, an annular block is detachably mounted on one side of the metal plate, and the annular quick-release has multiple through holes.
[0008] Preferably, each of the multiple through holes corresponds one-to-one with a multiple rotating rod, and the diameter of the through hole is equal to the diameter of the rotating rod.
[0009] Preferably, the annular block fits into the mounting groove, and the thickness of the annular block is equal to the depth of the mounting groove.
[0010] Preferably, both the inner and outer gaskets are made of polytetrafluoroethylene (PTFE).
[0011] Compared with the prior art, the beneficial effects of this utility model are: by setting a metal plate between the inner and outer gaskets, and setting an auxiliary installation mechanism by opening an installation groove in the annular groove of the metal plate, the device can be quickly positioned by the rotating rod of the auxiliary installation structure during use, and the entire device can be quickly positioned during installation, ensuring the accuracy of the installation position, preventing deviation and improving installation efficiency.

[0016] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figure 1-3 This utility model provides a technical solution: a convenient-installation polytetrafluoroethylene gasket, including an inner gasket 1, an outer gasket 2, and a metal plate 3 connecting the inner gasket 1 and the outer gasket 2. The inner gasket 1 has a central hole 4 at its center. The metal plate 3 is located between the inner gasket 1 and the outer gasket 2 and is fixedly connected to the inner gasket 1 and the outer gasket 2 respectively. Both sides of the metal plate 3 have annular grooves 5. The metal plate 3 has multiple mounting grooves 6 evenly distributed in the annular grooves 5. The metal plate 3 has an auxiliary mounting structure in the mounting grooves 6. The auxiliary mounting structure includes a rotating rod 7 and a connecting rod 8. The rotating rod 7 is entirely located in the mounting groove 6. The connecting rod 8 is fixedly located on the outer side of the middle part of the rotating rod 7. The other end of the connecting rod 8 is rotatably connected to the inner wall of the mounting groove 6.
[0018] The length of the rotating rod 7 is greater than the thickness of the metal plate 3, but less than the length of the mounting groove 6.
[0019] One side of the metal plate 3 is detachably fitted with an annular block 9, which has multiple through holes 10.
[0020] Each of the aforementioned through holes 10 corresponds one-to-one with a plurality of rotating rods 7, and the diameter of the through hole 10 is equal to the diameter of the rotating rod 7.
[0021] The annular block 9 fits into the mounting groove 6, and the thickness of the annular block 9 is equal to the depth of the mounting groove 6.
[0022] Both the inner gasket 1 and the outer gasket 2 are made of polytetrafluoroethylene.
[0023] Specifically, when using this utility model, the annular block 9 is removed from the annular groove 6. At this time, the entire device is placed horizontally by the metal plate 3. Under the action of gravity, the rotating rod 7 of the auxiliary installation structure rotates around the axis of the connecting rod 8 until the entire rotating rod 7 is in a vertical state. Finally, the annular block 9 is placed in the annular groove 5. During the placement process, the through holes 10 of the annular block 9 are respectively sleeved on the outside of the rotating rod 7, thereby effectively fixing the rotating rod 7. During subsequent installation, the end of the rotating rod 7 is made to cooperate with the positioning hole on the contact surface. During the installation process, the entire device is quickly positioned to ensure the accuracy of the installation position, prevent deviation, and improve installation efficiency.
