It is mainly used to isolate lubricated parts from power output parts in transmission components to prevent lubricating oil leakage. It plays a vital role in mechanical engineering. The diversity of its design, materials and application scenarios makes it an indispensable component for equipment sealing, for example;

[0003] Authorized publication number CN222229429U discloses an integral, connected oil seal assembly, including a metal skeleton, a polytetrafluoroethylene (PTFE) inner layer, and a PTFE outer layer. The PTFE inner layer is disposed on the outer side of the metal skeleton, and the PTFE outer layer is disposed on the outer side of the PTFE inner layer. A dustproof lip is provided at one end of the inner wall of the PTFE inner layer, and a sealing lip is provided at the other end. A spring-retaining lip is provided on the PTFE inner layer, and a spring groove is provided at the spring-retaining lip. This invention, by providing an oil inlet channel and an oil outlet channel, as well as a sealing piston, located between the upper and lower halves of the PTFE outer layer, utilizes the interaction between these elements to allow for lubricant replacement without disassembling the oil seal assembly, making lubricant replacement convenient and improving efficiency.

[0004] However, existing oil seal assemblies are not convenient for quick disassembly and replacement when they break, which often requires the replacement of the entire unit when damage occurs, thus affecting the efficiency of unit maintenance and increasing the maintenance cost of the unit.

[0005] Therefore, in order to address the above problems, there is an urgent need for innovative design based on the existing oil seal assembly. Utility Model Content

[0006] The purpose of this utility model is to provide an integrally connected oil seal assembly to solve the problem mentioned in the background art that it is not convenient to quickly disassemble and replace the device when it is damaged, which often requires the replacement of the entire device when damage occurs, thus affecting the maintenance and repair efficiency and increasing the maintenance cost of the device.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an integrally connected oil seal assembly, comprising: a first mounting frame, and a second positioning block disposed on the rear side of the first mounting frame, wherein the rear side of the second positioning block is connected to the second mounting frame;

[0008] Also includes:

[0009] The first positioning block is installed inside the first mounting frame, and a support plate is connected to the rear side of the first positioning block. A sealing ring is attached to the rear side of the support plate. A first guide groove is opened on the front side of the first mounting frame, and a connecting block is provided on the inner side of the first mounting frame. A reinforcing protective sleeve is connected to the inner side of the connecting block.

[0010] A limiting block is installed inside the second mounting frame, and a guide strip is connected to the outer side of the limiting block. An operating rod is connected to the upper side of the limiting block, and a damper is installed in the middle of the operating rod. A second guide groove is opened on the rear side of the second mounting frame, and a positioning component is installed on the outer side of the second mounting frame.

[0011] In one possible implementation, the connecting block and the reinforcing protective sleeve are engaged relative to each other, and the cross-section of the connecting block is a "T" shaped structure.

[0012] In one possible implementation, the first positioning block is engaged with the support plate, and the support plate is symmetrically arranged about the central axis of the first mounting frame.

[0013] In one possible implementation, the limiting block is engaged with the second positioning block, and the limiting block is slidably positioned relative to the guide strip.

[0014] In one possible implementation, the guide strip is set at an equal angle on the outside of the limiting block, and the limiting block is symmetrically arranged about the central axis of the second mounting frame.

[0015] In one possible implementation, the positioning component includes a first positioning ring mounted on the right side of the second mounting frame, and a third positioning block is provided inside the first positioning ring. A second positioning ring is provided on the left side of the first positioning ring, and a limit rod passes through the outer sides of the second positioning ring and the first positioning ring.

[0016] The third positioning block is engaged with both the first mounting frame and the second mounting frame.

[0017] In one possible implementation, the limiting rod is threadedly connected to both the second positioning ring and the first mounting frame, and the limiting rod is symmetrically arranged about the central axis of the second positioning ring.

[0018] Compared with the prior art, the beneficial effects of this utility model are: This integral, connected oil seal assembly facilitates quick disassembly and replacement of the device when damage occurs, eliminating the need to replace the entire device in case of damage, thus avoiding impacts on maintenance efficiency and reducing maintenance costs. Furthermore, the assembly process facilitates positioning and guidance during installation, reducing the likelihood of connection instability due to installation deviations, improving installation stability, and resulting in better performance. Specific details are as follows:

[0019] 1. By using a damper in conjunction with a guide bar to push the limit block and the operating rod to move downward, the limit block, which resets downward along the guide bar, engages with the second positioning block to install the first and second mounting frames in series. This allows operators to quickly disassemble and repair either the first or second mounting frame if it is damaged, reducing the maintenance cost of the device and improving its maintenance efficiency.

[0020] 2. The first and second mounting frames are fixed to the inner sides of the first and second mounting frames by the first positioning ring and the second positioning ring, so that the third positioning block, in conjunction with the first and second positioning rings, positions and installs the first and second mounting frames installed on the inner sides of the third mounting frame. This avoids unstable connection due to installation deviation, improves the installation stability of the device, and extends the service life of the device.

[0021] 3. By connecting the blocks and using the first and second mounting frames, the reinforcing protective sleeve is fixed to the inside of both frames. This reinforces and protects the oil seal, preventing it from deforming and breaking due to excessive pressure during use, and improving the strength of the oil seal. Attached Figure Description

[0029] 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.

[0030] Please see Figure 1-6 This utility model provides a technical solution: an integrally connected oil seal assembly, including a first mounting frame 1, a first guide groove 2, a connecting block 3, a reinforcing protective sleeve 4, a first positioning block 5, a support plate 6, a sealing ring 7, a second positioning block 8, a second mounting frame 9, a limiting block 10, a guide strip 11, an operating rod 12, a damper 13, a second guide groove 14, a first positioning ring 15, a third positioning block 16, a second positioning ring 17, and a limiting rod 18.

[0031] Specifically, such as Figure 1 , Figure 5 and Figure 6 As shown, by connecting the support plate 6 to the rear side of the first mounting frame 1 along the first positioning block 5 inside the first mounting frame 1, the first positioning block 5 engages and limits the support plate 6 due to the engaging connection between the first positioning block 5 and the support plate 6. At this time, pulling the operating rod 12 inside the second mounting frame 9 upward causes the operating rod 12 to move the limiting block 10 connected to its lower side upward, compressing the damper 13. Due to the sliding connection between the limiting block 10 and the guide strip 11, the limiting block 10 is guided and limited by the guide strip 11 during its upward displacement. Then, the second positioning block 8, which is set along the rear side of the first mounting frame 1, is installed on the rear side of the first mounting frame 1, so that the first mounting frame 1 cooperates with the second positioning block 8. The mounting frame 9 clamps the sealing ring 7 at the connection gap between the two. At this time, the pull on the operating rod 12 is released, causing the damper 13, which was compressed in the middle of the operating rod 12, to generate a rebound reaction force. At this time, the damper 13 pushes the limiting block 10 to move downward along the guide strip 11. Due to the engaging connection structure between the limiting block 10 and the second positioning block 8, the limiting block 10, which resets downward along the guide strip 11, engages with the second positioning block 8 to install the first mounting frame 1 and the second mounting frame 9 in series. This allows the operator to quickly disassemble and repair the first mounting frame 1 or the second mounting frame 9 if they are damaged. It also allows the operator to replace only the damaged parts, reducing the maintenance and repair costs of the device and improving the maintenance and repair efficiency of the device.

[0032] Specifically, such as Figure 2 , Figure 3 and Figure 4 As shown, by installing the first positioning ring 15 and the third positioning block 16 along the first guide groove 2 at the front end of the first mounting frame 1 and the second guide groove 14 at the rear side of the second mounting frame 9 on the right side of the first mounting frame 1 and the second mounting frame 9, and then rotating the limiting rod 18 that passes through its outer side, the limiting rod 18, due to its threaded connection with the first mounting frame 1 and the second mounting frame 9, causes the downward displacement of the limiting rod 18 to connect the first mounting frame 1, the second mounting frame 9 and the first positioning ring 15 together. Simultaneously, the second positioning ring 17 is installed along the first guide groove 2 and the second guide groove 14 on the left side of the first mounting frame 1 and the second mounting frame 9. Then, rotating the limiting rod 18 that passes through the other side causes the downward displacement of the limiting rod 18 to connect the first mounting frame 1, the second mounting frame 9 and the second positioning ring 17 together, thus completing the connection between the first mounting frame 1, the second mounting frame 9 and the second positioning ring 16. The installation and connection of the positioning ring 17 and the first positioning ring 15 are carried out by the third positioning block 16 in conjunction with the first positioning ring 15 and the second positioning ring 17 to position and install the first mounting frame 1 and the second mounting frame 9 installed inside them. This avoids unstable connection due to installation deviation, improves the installation stability of the device, and extends the service life of the device. At the same time, the reinforcing protective sleeve 4 is installed inside the first mounting frame 1 and the second mounting frame 9 along the connecting block 3. At this time, due to the "T"-shaped structure of the connecting block 3, the connecting block 3 connects and limits the reinforcing protective sleeve 4 installed inside it. At this time, the operator places the oil seal body inside the reinforcing protective sleeve 4, and the oil seal is supported and installed by the reinforcing protective sleeve 4. At this time, due to the structural strength of the reinforcing protective sleeve 4, the reinforcing protective sleeve 4 strengthens and protects the oil seal, preventing deformation and damage to the oil seal during use due to excessive pressure, and improving the service strength of the oil seal.
