Abstract
Description
Technical Field
[0001] This application relates to the technical field of sealing and plugging fittings, and in particular to a rivet sealing structure. Background Technology
[0002] During the production and processing of automotive parts such as metal housings, it is necessary to seal the process holes opened on the parts, such as key channels like oil and air passages. The sealing effect is directly related to the stability of the overall performance and operational reliability of the vehicle.
[0003] Currently, in actual production, rivet plugs are commonly used to seal process holes. A rivet plug consists of a spacer and a core. During sealing, a rivet gun is used to place the spacer and core into the hole, and then the rivet gun pulls the core, causing it to enter the spacer. As the core moves within the spacer, the spacer expands and deforms, eventually fitting against the inner wall of the process hole, thus sealing it.
[0004] However, once the core enters the spacer, the two are fixed together by friction. When the core is subjected to external force from the outside of the component, it is prone to falling off along the process hole, affecting the sealing performance. Summary of the Invention
[0005] To improve the sealing performance of process holes, this application provides a riveting sealing structure.
[0006] This application provides a riveted sealing structure, which adopts the following technical solution: A rivet sealing structure includes a spacer, a core, and an anti-detachment component; The spacer is provided with a movable port and a plug-in interface, and the movable port and the plug-in interface are connected. The anti-detachment component includes a rotating ring and a plug-in block; the rotating ring is rotatably connected to the core, and the plug-in block is connected to the rotating ring; the plug-in block moves within the movable port; The plug block is inserted into the plug interface, so that the positions of the core and the spacer are relatively fixed; The core is embedded in the spacer, so that the spacer abuts against the process hole.
[0007] By adopting the above technical solution, during the process of the core being embedded in the spacer, the movement of the core causes the spacer to gradually expand and deform outward until it presses against the inner wall of the process hole, thereby achieving the sealing of the process hole.
[0008] During the movement of the core, the plug block moves within the moving port to the position where the plug interface is aligned. At this point, the operator rotates the rotating ring to insert the plug block into the plug interface, thereby achieving relative fixation of the positions of the core and the spacer, further improving the stability of the connection between the core and the spacer, and reducing the possibility of the core falling out of the spacer.
[0009] Optionally, it may also include a pushing component disposed on the spacer, the pushing component being used to retract the spacer and disengage it from the inner wall of the process hole.
[0010] By adopting the above technical solution, when the sealing structure needs to be replaced, the spacer sleeve has expanded inside the process hole and is tightly abutting against the hole wall, making it difficult to pull the spacer sleeve out of the hole. Furthermore, the process of pulling it out easily causes wear on the inner wall of the process hole, thus affecting the overall quality of the component. By using a pushing component to push the expanded part of the spacer sleeve, the expanded part of the spacer sleeve deforms away from the hole wall, thereby breaking away from its contact with the inner wall of the process hole, making it easier to remove the spacer sleeve from the hole.
[0011] Optionally, the pushing assembly includes a pushing ring, which has a clearance groove and a connecting groove; the pushing ring is sleeved on the spacer, and the clearance groove communicates with the connecting groove; the plug block rotates from the plug interface into the connecting groove, so that the positions of the core and the pushing ring are relatively fixed.
[0012] By adopting the above technical solution, when it is necessary to remove the spacer, rotating the rotating ring moves the insert block into the connecting groove, thus fixing the position of the core and the pushing ring relatively. At this time, when the core moves along the direction of disengagement from the spacer within the hole, the insert block drives the pushing ring to move simultaneously and abut against the expanded part of the spacer. Under the push of the pushing ring, the expanded part of the spacer contracts and deforms, thereby disengaging from the inner wall of the process hole.
[0013] Optionally, the pushing assembly further includes a sealing ring disposed on the periphery of the pushing ring, the sealing ring abutting against the inner wall of the process hole.
[0014] By adopting the above technical solution, the sealing ring abuts against the inner wall of the process hole, which further improves the sealing performance of the process hole. At the same time, when the push ring moves, the sealing ring can provide a buffer, reducing the possibility of wear caused by friction between the push ring and the hole wall.
[0015] Optionally, a limiting block is provided inside the plug interface, and the limiting block abuts against the plug block.
[0016] By adopting the above technical solution, when the plug block moves into the plug interface, the plug block can abut against the limiting block. The abutment of the limiting block against the plug block can restrict the movement of the plug block, further improving the stability of the connection between the plug block and the spacer.
[0017] Optionally, the anti-detachment component further includes a toggle block, which is disposed on the rotating ring and is used to drive the rotating ring to rotate on the core.
[0018] By adopting the above technical solution, the toggle block is easy for staff to operate, making the rotating ring rotate and improving the ease of operation.
[0019] Optionally, the outer periphery of the core is provided with a relief surface, which abuts against and moves with the spacer, causing the spacer to expand and deform outward.
[0020] By adopting the above technical solution, when the core moves, the clearance surface abuts against the bottom of the spacer, so that as the core continues to move, the spacer gradually deforms and expands outward until it presses against the hole wall.
[0021] Optionally, the core is provided with a connecting hole for connecting with a rivet gun.
[0022] By adopting the above technical solution, the connecting hole facilitates the connection between the rivet gun and the core, and the core can be moved during the process.
[0023] Optionally, the core includes a core body and a sealing block; the sealing block is disposed on the periphery of the core body and abuts against the inner wall of the process hole; The core is embedded in the spacer, allowing the sealing block to be inserted into the movable port.
[0024] By adopting the above technical solution, when the core is embedded in the spacer, the sealing block is inserted into the moving port, thereby sealing the moving port and improving the sealing performance of the process hole.
[0025] Optionally, the sealing block is wrapped with a sealing gasket, which abuts against the inner walls of the spacer and the process hole, respectively.
[0026] By adopting the above technical solution, when the sealing block is located inside the moving port, the sealing gasket can improve the sealing performance between the sealing block and the spacer and the hole wall respectively, thereby achieving the sealing of the moving port and improving the sealing performance of the sealing structure.
[0027] In summary, this application includes at least one of the following beneficial technical effects: 1. Through the cooperation of the core, spacer, and anti-detachment component, during the process of the core being embedded in the spacer, the movement of the core causes the spacer to gradually expand and deform outward until it presses against the inner wall of the process hole, thus achieving a seal. During the core's movement, the insertion block moves within the moving port to the insertion interface position. At this point, the rotating ring rotates, inserting the insertion block into the insertion interface. The insertion block's position within the insertion interface ensures the relative fixation of the core and spacer, further improving the stability of the connection between the core and spacer and reducing the possibility of the core detaching from the spacer. 2. By incorporating a pushing component, when the sealing structure needs replacement, the spacer, having expanded within the process hole and tightly abutting against the hole wall, is not only difficult to remove but also prone to wear on the inner wall of the process hole during removal, thus affecting the overall quality of the component. By using the pushing component to push the expanded portion of the spacer, causing it to deform away from the hole wall, it disengages from the inner wall of the process hole, making it easier to remove the spacer from the hole. 3. By incorporating a rotating ring, when the spacer needs to be removed, rotating the ring moves the insert block into the connecting groove, fixing the core and the push ring in a relatively fixed position. At this point, as the core moves along the direction within the hole towards the spacer, the insert block drives the push ring to move simultaneously, abutting against the expanded portion of the spacer. Under the push of the push ring, the expanded portion of the spacer contracts and deforms, thus disengaging from its contact with the inner wall of the process hole. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.
[0031] This application discloses a riveted sealing structure. For example... Figure 1 and Figure 2 As shown, the rivet sealing structure includes a spacer 1, a core 2, an anti-detachment component 3, and a pushing component 4. In this embodiment, the spacer 1 is made of aluminum alloy, and the core 2 is provided with a connecting hole 211. The connecting hole 211 is provided with threads, and the rivet gun is connected to the core 2 through the connecting hole 211, thereby allowing the core 2 to move.
[0032] Specifically, such as Figure 2 and Figure 3 As shown, the anti-detachment component 3 includes a rotating ring 31, a plug-in block 32, and a toggle block 33. The rotating ring 31 is rotatably mounted on the core 2, the plug-in block 32 is fixedly connected to the rotating ring 31, and the toggle block 33 is fixedly connected to the rotating ring 31. The upper end face of the toggle block 33 is higher than the upper end face of the core 2, making it easier for the operator to operate the toggle block 33 to make the rotating ring 31 rotate on the core 2.
[0033] like Figure 4 and Figure 5 As shown, the spacer 1 has a movable port 11 and a plug-in port 12, and the plug-in port 12 is connected to the movable port 11. When the core 2 moves toward the spacer 1, the plug-in block 32 is located inside the movable port 11, so that the core 2 can move inside the spacer 1.
[0034] Among them, such as Figure 2 As shown, the core 2 has a clearance surface 212, which is a slope. The diameter of the side of the clearance surface 212 furthest from the rotating ring 31 is larger than the inner diameter of the spacer 1. This causes the spacer 1 to abut against the clearance surface, and as the core 2 is inserted into the spacer 1, the sidewall of the spacer 1 gradually deforms and expands outward until it presses against the inner wall of the process hole 5. When the insertion block 32 moves within the moving port 11 to a position aligned with the insertion interface 12, the core 2 is inserted into the spacer 1, pressing the sidewall of the spacer 1 against the process hole 5, thereby sealing the process hole 5.
[0035] Furthermore, such as Figure 6As shown, a sealing block 22 is fixedly connected to the core 2, and a sealing gasket is wrapped around the sealing block 22, which abuts against the inner wall of the process hole 5. During the process of the core 2 being inserted into the spacer 1, the sealing block 22 is inserted into the moving port 11. At this time, the sealing gasket abuts against the side of the moving port 11 and the inner wall of the process hole 5, thereby sealing the moving port 11 and improving the sealing performance of the process hole 5. In addition, when the operator places the core 2 and the spacer 1 into the process hole 5, the portion of the sealing block 22 located on the relief surface 212 can provide a placement reference for the moving port 11, thereby improving the accuracy of the alignment of the core 2 and the spacer 1 and improving the reliability of the core 2 being inserted into the spacer 1.
[0036] After the core 2 is embedded in the spacer 1 to seal the process hole, the insertion block 32 moves the port 11 to a position aligned with the insertion interface 12. At this time, the operator rotates the rotating ring 31 to allow the insertion block 32 to enter the insertion interface 12, thereby achieving relative fixation of the positions of the core 2 and the spacer 1.
[0037] Furthermore, such as Figure 5 As shown, a limiting block 13 is fixedly connected within the insertion interface 12. In this embodiment, the limiting block 13 is made of an elastic material. When the insertion block 32 is located within the insertion interface 12, the limiting block 13 abuts against the insertion block 32, which can restrict the movement of the insertion block 32 and further improve the connection stability between the rotating ring 31 and the spacer 1. After the spacer 1 and the core 2 are further connected through the insertion block 32, the insertion block 32 can restrict the movement direction of the core 2, thereby reducing the possibility of the core 2 coming out of the spacer 1 and improving the sealing reliability of the sealing structure of this application.
[0038] like Figure 2 and Figure 8 As shown, the pushing assembly 4 includes a pushing ring 41 and a sealing ring 42. The pushing ring 41 is sleeved on the spacer 1, and the sealing ring 42 is fixedly connected to the periphery of the pushing ring 41. A clearance groove 411 and a connecting groove 412 are provided on the pushing ring 41, and the clearance groove 411 and the connecting groove 412 are connected.
[0039] Among them, such as Figure 5 and Figure 8 As shown, when the pushing ring 41 is fitted onto the spacer 1, the clearance groove 411 overlaps with both the moving port 11 and the insertion port 12, so that as the insertion block 32 moves along the moving port 11 and enters the insertion port 12, the insertion block 32 also enters the clearance groove 411. Simultaneously, the connecting groove 412 also overlaps with the moving port 11, allowing the insertion block 32 to enter the connecting groove 412 by rotating the rotating ring 31.
[0040] It should be noted that after the insert block 32 enters the connecting groove 412, the positions of the core 2 and the pushing ring 41 are relatively fixed. Therefore, when the core 2 is removed from the spacer 1 from the outside of the hole towards the inside, the insert block 32 can drive the pushing ring 41 to move. To ensure the sealing of the process hole 5, when the sealing structure needs to be replaced after prolonged use, the spacer 1 expands inside the process hole 5 and tightly abuts against the hole wall. This makes it difficult to pull the spacer 1 out of the hole, and the removal process can easily cause wear on the inner wall of the process hole 5, affecting the overall quality of the product. This application addresses this by having the insert block 32 enter the connecting groove 412, thus fixing the positions of the core 2 and the pushing ring 41. When the pushing ring 41, along with the core 2, is removed from the spacer 1 from the outside of the hole towards the inside, the pushing ring 41 can push the expanded portion of the spacer 1 to deform away from the hole wall, causing the spacer 1 to contract. This allows the spacer 1 to disengage from the hole wall, making it easier to remove the spacer 1 from the hole.
[0041] In addition, the sealing ring 42 is fixed to the outer wall of the push ring 41, and the sealing ring 42 abuts against the inner wall of the process hole 5, further improving the sealing performance. At the same time, when the push ring 41 moves, the sealing ring 42 can provide cushioning, reducing the possibility of wear on the hole wall caused by friction between the push ring 41 and the hole wall of the process hole 5, thus ensuring the production quality of the product.
[0042] The implementation principle of a riveted sealing structure in this application embodiment is as follows: When it is necessary to seal the process hole 5, first use a rivet gun to place the core 2 and the spacer 1 into the process hole, and then control the rivet gun to move the core 2 toward the spacer 1 so that the core 2 is embedded in the spacer 1.
[0043] During the process of the core 2 being embedded into the spacer 1, the spacer 1 gradually expands and deforms outward after contacting the relief surface 212 until the core 2 is embedded inside the spacer 1. When the core 2 is embedded inside the spacer 1, the core 2 presses the spacer 1 tightly against the process hole 5. At the same time, the sealing block 22 seals the moving port 11. With the cooperation of the spacer 1 and the core 2, the process hole 5 is sealed.
[0044] Meanwhile, during the process of inserting the core 2 into the spacer 1, the insertion block 32 moves along the moving port 11 to the position connected with the insertion interface 12. At this time, the operator rotates the rotating ring 31 by turning the block 33, inserts the insertion block 32 into the insertion interface 12, and fixes the relative position of the core 2 and the spacer 1, reducing the possibility of the core 2 and the spacer 1 falling off.
[0045] When the sealing structure needs to be replaced, the operator rotates the rotating ring 31 by using the actuating block 33, inserting the plug block 32 into the connecting groove 412. At this time, the operator pushes the core 2 from the outside of the hole towards the inside. The movement of the core 2, through the plug block 32, causes the pushing ring 41 to move. As the pushing ring 41 moves, it deforms the expansion part of the spacer 1 away from the hole wall, causing the spacer 1 to disengage from the hole wall, thus facilitating the removal of the spacer 1.
[0046] The sealing structure of this application, through the cooperation of the anti-detachment component 3 and the pushing component 4, improves the connection stability between the core 2 and the spacer 1, and reduces the possibility of the core 2 and the spacer 1 falling off. At the same time, it makes the sealing structure easy to disassemble, reducing wear on the hole wall during the disassembly process.
[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
