Abstract
Description
Technical Field
[0001] This utility model relates to the field of rubber products technology, specifically to a conductive fluororubber product. Background Technology
[0002] Conductive fluororubber products are a special rubber material with excellent electrical conductivity. They are mainly composed of a fluororubber matrix and conductive fillers (such as conductive carbon black, carbon nanotubes, graphite, etc.). These materials impart good electrical conductivity and physical properties by uniformly dispersing the conductive fillers in the fluororubber.
[0003] A search revealed a Chinese patent with authorization number CN221170761U, which discloses a conductive fluororubber product including a driving component, a locking component, a pressure plate, and limiting strips to allow the free ends of multiple sets of limiting strips to enter multiple sets of limiting grooves. This structure facilitates the movement of the locking component into or out of the grooves and is relatively simple to operate. After the annular folded airbag is inflated, the outer surface of the annular folded airbag contacts the tube wall. Compared with the existing inflatable sealing ring structure, this structure increases the contact area, thereby increasing the sealing performance.
[0004] One of the aforementioned patents has the following drawbacks: the circular folding airbag is squeezed by the drive assembly, locking assembly, pressure plate and limiting strip to squeeze the external circular opening that needs to be sealed. However, in actual use, after too many uses, the subsequent sealing performance will be affected due to the elastic fatigue of the spring or the deformation of the circular folding airbag. Utility Model Content
[0005] Based on this, the purpose of this utility model is to provide a conductive fluororubber product to solve the technical problem that after excessive use, the subsequent sealing performance will be affected due to the elastic fatigue of the spring or the deformation of the annular folding airbag.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a conductive fluororubber product, comprising a sealing plug, a sealing gasket at the top of the sealing plug, a threaded rod extending into the interior of the sealing plug at one end inside the sealing gasket, a movable block engaging with the threaded rod at the outside of the threaded rod, a plurality of support rods movably connected to the outside of the movable block, an extrusion plate at one end of the support rod, and a top plate movably connected to both ends of the extrusion plate.
[0007] By adopting the above technical solution, during use, the staff inserts the entire sealing plug into the through hole that needs to be sealed, ensuring that the outer side of the sealing plug is approximately in contact with the outer side of the through hole that needs to be sealed.
[0008] Then, the staff manually rotates the knob to make the threaded rod at the bottom of the knob rotate synchronously. When the threaded rod rotates, it will drive the moving block connected to it on the outside to move along the thread. When the moving block moves downward, it will drive the multiple sets of support rods connected to it on the outside to change the angle around the protrusion as the axis.
[0009] The compression plate connected to the other side of the support rod is pushed outward. When the compression plate is pushed outward, the convex shape of the outer side of the compression plate will evenly compress the sealing plug, allowing the sealing plug to be supported outward. This deformation will compress the contact area with the outer through hole, thereby achieving a complete seal. Through this structure, the size of the sealing plug can also be adjusted in real time to prevent poor contact with the external through hole due to the rubber on the outer side of the sealing plug, which would lead to air leakage.
[0010] Furthermore, when the extrusion plate moves outward, there are two sets of top plates between the two sets of extrusion plates, and the extrusion plate and the top plate are connected by a fixing block, which plays the role of rotation and limiting. There are also two sets of rotating shafts between the two sets of top plates to cooperate with the movement of the two sets of top plates, so that the two sets of top plates can be opened up during the forward movement of the extrusion plate and squeeze the sealing plug from the inside.
[0011] Specifically, a certain degree of protrusion will be set at the approximate position where the sealing plug meets the top plate inside, in order to compensate for the insufficient pushing distance of the top plate;
[0012] The above structure ensures that the sealing plug will not deform due to excessive use, thus maintaining the sealing performance and allowing for electrical conductivity while sealing.
[0013] Furthermore, a knob is provided at the top of the threaded rod, and multiple sets of corrugated ridges are provided on the outer side of the knob.
[0014] By adopting the above technical solution, a knob set at the top of the threaded rod ensures that external personnel can adjust the threaded rod by rotating it, thereby adjusting the internal sealing plug.
[0015] Furthermore, the support rod and the moving block are limited by a protrusion, and a limiting rod that cooperates with the support rod is provided on one side of the extrusion plate.
[0016] By adopting the above technical solution, the support rod and the moving block are limited by the protrusion to prevent them from shifting or falling off during use.
[0017] Furthermore, a fixing block is provided at each end of the extrusion plate, and a movable cavity that cooperates with the extrusion plate is opened inside the top plate.
[0018] By adopting the above technical solution, the fixing blocks set at both ends of the extrusion plate ensure that the position of the top plate will not shift or fall off due to changes in angle.
[0019] Furthermore, the sealing plug is provided with a limiting ring that cooperates with the threaded rod, and the limiting ring and the threaded rod rotate through a bearing.
[0020] By adopting the above technical solution, the limiting ring set inside the sealing plug ensures that the threaded rod will not wobble while rotating.
[0021] Furthermore, the sealing plug has multiple sets of protrusions that cooperate with the top plate inside, and two sets of rotating shafts are also provided between the two sets of top plates.
[0022] By adopting the above technical solution, the bulge inside the sealing plug allows the movement of the top plate to support the sealing plug for sealing.
[0023] In summary, this utility model has the following beneficial effects: When using this utility model, the operator inserts the sealing plug into the through hole to be sealed, so that the outer side of the sealing plug roughly fits against the outer side of the through hole. Then, the knob is turned to drive the bottom threaded rod to rotate synchronously, causing the threaded moving block to move down. The moving block drives the support rod to change the angle around the protrusion as the axis. The support rod pushes the extrusion plate to extrude outward, using the outer convex surface to evenly extrude the sealing plug, causing it to deform and expand, increasing the contact area with the through hole to achieve a seal. It can also adjust the size of the sealing plug in real time to prevent the rubber from weakening and causing air leakage. When the extrusion plate moves, it is connected to the middle top plate through the fixed block, which plays a role in rotation limit. The rotating shaft between the top plates moves and expands in coordination with it, extruding the sealing plug from the inside. A protrusion is provided at the contact point between the sealing plug and the top plate to compensate for insufficient pushing distance. This structure ensures that it still seals well after multiple uses and also has the function of conducting electricity. Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0031] The embodiments of this utility model will be described below based on its overall structure.
[0032] A conductive fluororubber product, such as Figure 1-5 As shown, it includes a sealing plug 1, a sealing gasket 2 is provided at the top of the sealing plug 1, and a threaded rod 4 is provided inside the sealing gasket 2, one end of which extends into the interior of the sealing plug 1. Then, by manually turning the knob 3, the threaded rod 4 at the bottom of the knob 3 rotates synchronously. When the threaded rod 4 rotates, it will drive the moving block 11 connected to it on its outer side to move along the thread. When the moving block 11 moves downward, it will drive the multiple sets of support rods 9 connected to it on its outer side to change the angle around the protrusion 7 as the axis.
[0033] For example, a movable block 11 that meshes with the threaded rod 4 is provided on the outside of the threaded rod 4. Multiple sets of support rods 9 are movably connected to the outside of the movable block 11. A pressing plate 6 is provided at one end of the support rod 9. A top plate 5 is movably connected to both ends of the pressing plate 6. The pressing plate 6 movably connected to the other side of the support rod 9 is pushed outward. When the pressing plate 6 is pushed outward, the convex shape of the outer side of the pressing plate 6 will evenly press the sealing plug 1 so that the sealing plug can be supported outward. In this way, the contact area with the outer through hole is compressed through deformation, thereby achieving a complete seal. Through this structure, the size of the sealing plug 1 can also be adjusted in real time to prevent poor contact with the external through hole due to the rubber on the outer side of the sealing plug 1, which would lead to air leakage.
[0034] For example, a knob 3 is provided at the top of the threaded rod 4, and multiple sets of corrugated ridges are provided on the outside of the knob 3. The support rod 9 and the moving block 11 are limited by the ridge block 7. A limiting rod that cooperates with the support rod 9 is provided on one side of the extrusion plate 6. Fixed blocks 12 are provided at both ends of the extrusion plate 6. When the extrusion plate 6 moves outward, two sets of top plates 5 are provided between the two sets of extrusion plates 6. The extrusion plate 6 and the top plates 5 are connected by the fixed blocks 12, which play the role of rotation and limiting. Two sets of rotating shafts 8 are provided between the two sets of top plates 5 to cooperate with the movement of the two sets of top plates 5, so that the two sets of top plates 5 can be opened up during the forward movement of the extrusion plate 6, and the sealing plug 1 is squeezed from the inside.
[0035] For example, the top plate 5 has an internal movable cavity that cooperates with the extrusion plate 6, and the sealing plug 1 has multiple sets of protrusions that cooperate with the top plate 5. There are also two sets of rotating shafts 8 between the two sets of top plates 5. The sealing plug 1 has a certain degree of protrusion at the approximate position where it connects with the top plate 5, in order to compensate for the insufficient pushing distance of the top plate 5.
[0036] The working principle of this utility model is as follows: When in use, the staff inserts the sealing plug 1 into the through hole that needs to be sealed, ensuring that the outer side of the sealing plug 1 is approximately in contact with the outer side of the through hole that needs to be sealed.
[0037] Then, the staff manually rotates the knob 3 to make the threaded rod 4 at the bottom of the knob 3 rotate synchronously. When the threaded rod 4 rotates, it will drive the moving block 11 connected to it on the outside to move along the thread. When the moving block 11 moves downward, it will drive the multiple sets of support rods 9 connected to it on the outside to change the angle around the protrusion 7 as the axis.
[0038] And push the extrusion plate 6 connected to the other side of the support rod 9 outward. When the extrusion plate 6 is pushed outward, the convex shape of the outer side of the extrusion plate 6 will evenly extrude the sealing plug 1, so that the sealing plug can be supported outward. In this way, the contact area with the outer through hole is compressed through deformation, thereby achieving a complete seal. Through this structure, the size of the sealing plug 1 can also be adjusted in real time to prevent poor contact with the external through hole due to the rubber on the outer side of the sealing plug 1, which would lead to air leakage.
[0039] Furthermore, when the extrusion plate 6 moves outward, two sets of top plates 5 are provided between the two sets of extrusion plates 6, and the extrusion plate 6 and the top plate 5 are connected by a fixing block 12, which plays the role of rotation and limiting. In addition, two sets of rotating shafts 8 are provided between the two sets of top plates 5 to cooperate with the movement of the two sets of top plates 5, so that the two sets of top plates 5 can be opened up during the forward movement of the extrusion plate 6, and the sealing plug 1 is squeezed from the inside.
[0040] Specifically, the sealing plug 1 will have a certain degree of protrusion at the approximate position where it connects with the top plate 5 inside, in order to compensate for the insufficient pushing distance of the top plate 5.
[0041] The above structure ensures that the sealing plug will not deform due to excessive use, thus maintaining the sealing performance and allowing for electrical conductivity while sealing.
