Description
Technical Field
[0001] This utility model relates to the field of sealing connection technology, and in particular to a special sealing connection device for preventing leakage. Background Technology
[0002] Special seals refer to sealing elements used in specific and harsh working conditions to meet special performance requirements. They have characteristics such as resistance to high temperature, high pressure, and strong corrosion, and are used in fields such as nuclear power and aerospace to ensure that the system medium does not leak and that operation is safe.
[0003] Special seals are typically used between connectors to prevent leakage of fluid media (such as gas, liquid, etc.) to ensure the system's sealing and normal operation. Leak-proof special seal connection devices connect two pipes, equipment, or components through connectors and use seals to seal them, thereby effectively preventing media leakage and ensuring the system operates stably and reliably under complex conditions.
[0004] However, existing leak-proof special sealing connection devices have the following shortcomings:
[0005] In the existing technology, the connectors of the anti-leakage special sealing component connection device are usually fastened with multiple bolts and nuts. However, since the connection device is generally heavy, the workers usually need to insert the bolts into the corresponding connection holes one by one for assembly. In addition, the connectors need to be frequently adjusted during the operation to achieve overlapping of the connection hole positions, which makes the installation process time-consuming and labor-intensive, resulting in low installation efficiency and increased labor and time costs.
[0006] Therefore, we propose a special leak-proof sealing connection device to solve the problems mentioned above. Utility Model Content
[0007] The purpose of this utility model is to provide a special sealing connection device for preventing leakage. By utilizing the quick fixing function of the sliding engagement component, two connecting flanges can quickly form a stable tenon and mortise structure, which promotes the rapid alignment of the connecting holes of the two connecting flanges, thereby solving the problems mentioned in the background art.
[0008] To achieve the above objectives, the present invention adopts the following technical solution: a leak-proof special sealing connection device, comprising two connecting pipes, each of which has a connecting flange fixedly fitted on its outer wall; an embedded ring fixedly connected to one side of the outer wall of one of the connecting flanges; an embedded groove formed on one side of the outer wall of the other of the connecting flanges, with the outer wall of the embedded ring movably inserted into the embedded groove; a set of annular limiting grooves formed on one side of the outer wall of the embedded ring; a circular sliding groove formed on the inner wall of one of the connecting flanges; a circular slider slidably embedded in the inner wall of the circular sliding groove; a set of annular limiting blocks fixedly connected to one side of the outer wall of the circular slider, with the outer wall of the set of annular limiting blocks movably inserted into the set of annular limiting grooves; a pull block fixedly connected to the outer wall of the circular slider, with a fixing groove formed on one side of the outer wall of the pull block.
[0009] Preferably, an installation block is fixedly connected to the outer wall of one of the two connecting flanges, the top of the installation block is provided with a movable groove, and the movable block is slidably embedded in the inner wall of the movable groove.
[0010] Preferably, a fixing block is fixedly connected to one side of the outer wall of the movable block, and the outer wall of the fixing block is movably inserted into the inside of the fixing groove. A return spring is fixedly connected to one side of the outer wall of the movable block.
[0011] Preferably, a set of connection holes is provided on one side of the outer wall of each of the two connecting flanges, a sealing gasket is movably contacted between the outer walls of the two connecting flanges, and a connecting bolt is movably inserted between the inner surfaces of the two sets of connection holes.
[0012] Preferably, a connecting nut is threaded onto the outer wall of each set of connecting bolts, and a first metal washer is movably fitted onto the outer wall of each set of connecting bolts.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0016] 1. In this utility model, through the interaction of the various components of the device, the rapid fixing function of the sliding engagement component allows the two connecting flanges to quickly form a stable tenon and mortise structure, which promotes the rapid alignment of the connecting holes of the two connecting flanges. In this way, efficient pre-positioning of the connecting flanges is achieved. During the installation process, workers do not need to frequently adjust the connecting flanges to align the connecting holes, thereby reducing the difficulty of operation and labor intensity. The installation process becomes simple and convenient, significantly improving installation efficiency, thereby reducing labor and time costs. Furthermore, the addition of tenon and mortise structure fixing on the basis of bolt fixing further enhances the stability and reliability of the connection.
[0017] 2. In this utility model, through the interaction of the various components of the device and the synergistic effect of the bolt assembly's threads, the clamping ring can apply a stable clamping force to a set of connecting nuts. This provides an additional layer of reliable clamping protection to the set of connecting nuts on top of the original thread tightening force. Under vibration or impact conditions, it can effectively prevent the nuts from coming loose due to vibration, shaking, or other factors, thereby avoiding loosening of the connection and preventing a series of problems such as sealing failure, and effectively ensuring the stability and sealing of the connection.

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0026] Example 1, as shown in the attached document Figure 1 - Appendix Figure 5 As shown, this utility model provides a technical solution: a leak-proof special sealing connection device, including two connecting pipes 1, each of which has a connecting flange 2 fixedly fitted on its outer wall. One of the connecting flanges 2 has an embedded ring 3 fixedly connected to one side of its outer wall. The other connecting flange 2 has an embedded groove 4 on one side of its outer wall, with the outer wall of the embedded ring 3 movably inserted into the groove 4. A set of annular limiting grooves 5 are provided on one side of the outer wall of the embedded ring 3. One of the connecting flanges 2 has a circular sliding groove 6 on its inner wall, with a circular slider 7 slidably embedded in the inner wall of the circular sliding groove 6. The outer wall of the circular slider 7... A set of annular limiting blocks 8 are fixedly connected to one side, and the outer wall of the set of annular limiting blocks 8 is movably inserted into the interior of a set of annular limiting grooves 5. A pull block 9 is fixedly connected to the outer wall of the circular slider 7. A fixing groove 10 is opened on one side of the outer wall of the pull block 9. An installation block 11 is fixedly connected to the outer wall of one of the two connecting flanges 2. A movable groove 12 is opened on the top of the installation block 11. A movable block 13 is slidably embedded in the inner wall of the movable groove 12. A fixing block 14 is fixedly connected to one side of the outer wall of the movable block 13, and the outer wall of the fixing block 14 is movably inserted into the interior of the fixing groove 10. A return spring 15 is fixedly connected to one side of the outer wall of the movable block 13.
[0027] The effect achieved by the entire embodiment 1 is as follows: When it is necessary to connect two connecting flanges 2, first insert the embedded ring 3 on one side of the outer wall of one connecting flange 2 into the embedded groove 4 on the corresponding side of the outer wall of the connecting flange 2. Then, rotate the pull block 9 and pull the movable block 13. The pull block 9 drives the circular slider 7 to slide in the circular groove 6. During this process, a set of annular limiting blocks 8 are driven and moved into the corresponding annular limiting groove 5. At the same time, pull the movable block 13 to make the fixed block 14 enter the movable groove 12. The movement of the movable block 13 will compress the return spring 15, causing it to produce elastic deformation and store elastic potential energy. When a set of annular limiting blocks 8 are completely inserted into the corresponding annular limiting groove 5, the position of the fixed block 14 and the pull block are... The fixing groove 10 on one side of the outer wall corresponds to the restoring force generated by the release of elastic potential energy by the return spring 15, so that the fixing block 14 is inserted into the corresponding fixing groove 10. At this time, a set of annular limiting blocks 8 are inserted into a set of annular limiting grooves 5, and the two connecting flanges 2 form a stable tenon and mortise structure. The connecting holes 16 of the two connecting flanges 2 also correspond to each other. At this time, the workers can easily use the bolt assembly to further strengthen the fixing and sealing of the connecting flanges 2. In this way, the workers can quickly connect the two connecting flanges 2 and concentrate on the installation operation of the bolt assembly, thereby improving the installation efficiency. In addition, the tenon and mortise structure fixing is added on the basis of bolt fixing, thereby improving the stability and reliability of the connection.
[0028] Example 2, as Figure 2-5 As shown, a set of connecting holes 16 are provided on one side of the outer wall of each of the two connecting flanges 2. A sealing gasket 17 is movably contacted between the outer walls of the two connecting flanges 2. A connecting bolt 18 is movably inserted between the inner surfaces of the two sets of connecting holes 16. A connecting nut 19 is threadedly connected to the outer surface of the set of connecting bolts 18. A first metal washer 20 is movably fitted on the outer surface of the set of connecting bolts 18. A set of threaded grooves 21 are provided on one side of the outer wall of one of the two connecting flanges 2. A fixing bolt 22 is threadedly connected to the inner surface of the set of threaded grooves 21. A clamping ring 23 is movably fitted between the outer surfaces of the set of fixing bolts 22. A second metal washer 24 is movably fitted on the outer surface of the set of fixing bolts 22.
[0029] The effect achieved by the entire embodiment 2 is as follows: After the two connecting flanges 2 are securely fixed by the threaded engagement of a set of connecting bolts 18 and a set of connecting nuts 19, the operator places the clamping ring 23 between the outer walls of the set of connecting nuts 19 and screws the fixing bolts 22 into the corresponding threaded grooves 21, thereby fixing the clamping ring 23 to the top of the set of connecting nuts 19. By placing a second metal washer 24 on the outer wall of the set of fixing bolts 22, the fixing effect of the clamping ring 23 can be made more stable. In this way, the clamping ring 23 can apply a downward clamping force to the set of connecting nuts 19, thereby adding an extra layer of clamping force to the connecting nuts 19 on the basis of the original thread tightening force. This can effectively prevent the nuts from coming loose due to vibration, shaking, etc. in vibration environment or impact conditions, resulting in problems such as loose connection and seal failure.
[0030] The working principle of the entire device is as follows: First, a sealing gasket 17 is placed between the two connecting flanges 2. Then, the two connecting flanges 2 are connected. The operator first inserts the embedded ring 3 on one side of the outer wall of one connecting flange 2 into the corresponding embedded groove 4. Then, the pull block 9 is rotated and the movable block 13 is pulled. The pull block 9 drives the circular slider 7 to slide within the circular groove 6. As the circular slider 7 slides, it drives a set of annular limit blocks 8 to move towards the corresponding annular limit groove 5. Simultaneously, pulling the movable block 13 causes the fixed block 14 to enter the movable groove 12. During this process, the movement of the movable block 13 compresses the return spring 15, causing it to undergo elastic deformation and store elastic potential energy. When the set of annular limit blocks 8 are fully engaged in the corresponding annular limit groove 5, the position of the fixed block 14 corresponds exactly to the fixed groove 10 on one side of the outer wall of the pull block 9. The restoring force generated by the release of elastic potential energy by the return spring 15 causes the fixed block 14 to engage in the corresponding fixed groove 12. Inside groove 10, a set of annular limiting blocks 8 are inserted into a set of annular limiting grooves 5, and the two connecting flanges 2 form a stable tenon and mortise structure. At this time, the connecting holes 16 of the two connecting flanges 2 are aligned with each other, and the workers can insert a set of connecting bolts 18 into the corresponding connecting holes 16. Through the synergistic action of a set of connecting nuts 19 and a set of first metal washers 20, the two connecting flanges 2 are fixed by thread engagement. Subsequently, the workers put the clamping ring 23 between the outer walls of the set of connecting nuts 19, and then screw the fixing bolts 22 into the corresponding threaded grooves 21, thereby fixing the clamping ring 23 to the top of the set of connecting nuts 19. By putting the second metal washer 24 on the outer wall of the set of fixing bolts 22, the fixing effect of the clamping ring 23 can be made more stable, so that the clamping ring 23 can apply a clamping force to the set of connecting nuts 19, thereby adding an extra layer of clamping force to the set of connecting nuts 19 on the basis of the original threaded fastening force.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
