Description

Technical Field

[0001] This utility model relates to the field of MPP cable protection pipe technology, and in particular to an MPP cable protection pipe with multiple sealing and convenient connection system. Background Technology

[0002] MPP cable protection pipe is a special pipe made of modified polypropylene as the main raw material through processes such as extrusion molding. It is mainly used for cable laying protection in the power and communication fields. It can effectively isolate cables from damage caused by external factors such as soil corrosion, mechanical impact, and acid and alkali corrosion in cable laying scenarios such as underground laying and conduit laying. At the same time, it has good insulation, high temperature resistance and aging resistance, and can adapt to different geological conditions and construction environments. It provides safety protection for the long-term stable operation of cables, and is easy to install. It is a key supporting material for ensuring cable safety and extending cable service life in cable laying projects.

[0003] During the use of MPP cable protection pipes, multiple MPP cable protection pipes need to be installed. Over the long term, the connections may loosen. Current technology generally cannot test the sealing of these connections. To ensure the effectiveness of the equipment, multiple MPP cable protection pipes are usually replaced as a whole, which is costly and causes inconvenience to users.

[0004] An existing patent (publication number: CN218040620U) discloses an MPP cable protection pipe that is easy to maintain, belonging to the field of MPP cable protection pipes. This easy-to-maintain MPP cable protection pipe includes an MPP cable protection pipe body. One end of the MPP cable protection pipe body is fixedly connected to a plug assembly, which includes an annular inner plug. Around the annular inner plug, arc-shaped compression plates are fixedly connected by compression springs. The other end of the MPP cable protection pipe body is provided with an auxiliary insertion assembly, which includes a slot. An annular ring is fixedly connected to the outer surface of the other end of the MPP cable protection pipe body. A smooth rod is slidably connected around the inside of the annular ring, and a support block is fixedly connected to one end of the smooth rod. This allows for separate inspection of the connections of multiple MPP cable protection pipes. Loose connections of MPP cable protection pipes can be addressed promptly, thereby reducing equipment costs to a certain extent and facilitating operation for staff.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, existing MPP cable protection pipes generally suffer from insufficient sealing performance during connection. Excessive gaps at the pipe connection points can allow soil moisture and impurities to seep in, corroding the internal cables. Furthermore, the pipes lack targeted structural reinforcement components after connection, making the connection ends prone to deformation and misalignment under external mechanical forces, further compromising the sealing effect.

[0006] To address this, an MPP cable protection pipe with multiple sealing features and a convenient connection system is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide an MPP cable protection pipe with multiple sealing and convenient connection system, which can solve the problem that the existing MPP cable protection pipes generally have insufficient sealing performance when connected. The pipe connection part is prone to soil moisture and impurities seeping in due to excessive gaps, which corrodes the internal cable. Furthermore, the pipe body lacks targeted structural reinforcement components after connection, and the connection end is prone to deformation and misalignment when subjected to external mechanical forces, which further damages the sealing effect.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an MPP cable protection pipe with a multi-seal and convenient connection system, comprising a first pipe body, a second pipe body disposed on the right side of the first pipe body, a protrusion disposed on the right side of the first pipe body, the surface of the protrusion being inserted into the inner wall of the second pipe body, a positioning frame disposed on the surface of the first pipe body, a first reinforcing mechanism fixedly connected to the left side of the positioning frame, and a second reinforcing mechanism fixedly connected to the right side of the positioning frame, the surface of the first reinforcing mechanism being engaged with the inner wall of the first pipe body, and the surface of the second reinforcing mechanism being engaged with the inner wall of the second pipe body.

[0016] Preferably, a first mounting plate is fixedly connected to both the front and rear sides of the base assembly, and a second mounting plate is fixedly connected to both the front and rear sides of the positioning frame.

[0017] Preferably, a knob is movably connected to the inner wall of the second mounting plate, and the surface of the knob is threadedly connected to the inner wall of the first mounting plate.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This application establishes a first reinforcing mechanism, which, together with a second reinforcing mechanism, forms a collaborative support structure via a positioning frame. The first reinforcing mechanism is engaged with the inner wall of the first tube, and the second reinforcing mechanism is engaged with the inner wall of the second tube. This structure can reinforce the connection ends of the first and second tubes respectively, effectively resisting external mechanical forces from squeezing and impacting the connection between the first and second tubes. This prevents the connection ends from deforming due to stress, thus avoiding sealing failure. At the same time, the two maintain a relatively fixed positional relationship under the action of the positioning frame, which can accurately maintain the coaxiality of the first and second tubes, preventing misalignment when the first and second tubes are connected, and further ensuring connection stability.

[0020] 2. This application, by setting a protrusion, directly fills the gap between the two pipes by fitting the protrusion with the inner wall of the second pipe during use, thus initially improving the sealing performance of the connection and preventing soil moisture and impurities from seeping into the pipe and corroding the cable. The positioning frame provides an installation carrier for the first and second reinforcing mechanisms, enabling the first and second reinforcing mechanisms to be quickly and correspondingly assembled to the first and second pipes. The pipe connection and reinforcement structure can be installed synchronously without complicated tools, simplifying the construction process. Attached Figure Description

[0028] 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.

[0029] Please see Figure 1-6 The present invention provides the following technical solution:

[0030] An MPP cable protection pipe with a multi-seal and convenient connection system includes a first pipe body 1, a second pipe body 3 on the right side of the first pipe body 1, a protrusion 4 on the right side of the first pipe body 1, the surface of the protrusion 4 being inserted into the inner wall of the second pipe body 3, a positioning frame 5 on the surface of the first pipe body 1, a first reinforcing mechanism 2 fixedly connected to the left side of the positioning frame 5, and a second reinforcing mechanism 6 fixedly connected to the right side of the positioning frame 5, the surface of the first reinforcing mechanism 2 being engaged with the inner wall of the first pipe body 1, and the surface of the second reinforcing mechanism 6 being engaged with the inner wall of the second pipe body 3.

[0031] In this embodiment: By setting a first reinforcing mechanism 2, the first reinforcing mechanism 2 and the second reinforcing mechanism 6 form a cooperative support structure through the positioning frame 5. The first reinforcing mechanism 2 is engaged with the inner wall of the first tube 1, and the second reinforcing mechanism 6 is engaged with the inner wall of the second tube 3. This can structurally strengthen the connecting ends of the first tube 1 and the second tube 3 respectively, effectively resisting the squeezing and impact of external mechanical forces on the connecting parts of the first tube 1 and the second tube 3, and preventing the sealing failure caused by deformation of the connecting ends of the first tube 1 and the second tube 3 due to force. At the same time, under the action of the positioning frame 5, the two maintain a relatively fixed positional relationship, which can accurately maintain the first tube 1 and the second tube 3. The coaxiality is ensured to prevent misalignment when the first pipe body 1 and the second pipe body 3 are connected, further guaranteeing the connection stability. By setting the protrusion 4, the protrusion 4 fits against the inner wall of the second pipe body 3 during use, directly filling the gap between the two pipe bodies, initially improving the sealing performance of the connection, and preventing soil moisture, impurities, etc. from seeping into the pipe from the connection gap and corroding the cable. The positioning frame 5 provides an installation carrier for the first reinforcing mechanism 2 and the second reinforcing mechanism 6, so that the first reinforcing mechanism 2 and the second reinforcing mechanism 6 can be quickly and correspondingly assembled to the first pipe body 1 and the second pipe body 3. The pipe body connection and the synchronous installation of the reinforcing structure can be completed without complicated tools, simplifying the construction process.

[0032] Specifically, such as Figure 4 As shown, a first sealing ring 7 is bonded to the inner wall of the protrusion 4, and the surface of the first sealing ring 7 is engaged with the inner wall of the second tube 3.

[0033] Specifically, such as Figure 4 As shown, a second sealing ring 8 is bonded to the inner wall of the first tube 1, and the surface of the second sealing ring 8 is engaged with the inner wall of the second tube 3.

[0034] Specifically, such as Figure 3 As shown, the inner wall of the second tube 3 is provided with a positioning groove 9 that cooperates with the protrusion 4, and the inner wall of the second tube 3 is provided with a sealing groove 10 that cooperates with the second sealing ring 8.

[0035] In this embodiment: by setting the first sealing ring 7, the gap between the protrusion 4 and the second pipe 3 can be further filled on the basis of the insertion and cooperation, forming a sealing structure, which greatly improves the sealing reliability of the connection part and effectively prevents soil moisture and impurities from seeping in. By setting the second sealing ring 8, an additional sealing protection can be formed on the connection end face of the first pipe 1 and the second pipe 3. Together with the first sealing ring 7, a multi-seal system is constructed to further enhance the sealing effect and prevent the cable from being corroded by the outside. The positioning groove 9 opened in the inner wall of the second pipe 3 can guide the protrusion 4 to be accurately inserted into the second pipe 3, ensuring that the two pipes are quickly aligned when connected, improving the installation efficiency. At the same time, the sealing groove 10 that cooperates with the second sealing ring 8 can limit and fix the second sealing ring 8, preventing the second sealing ring 8 from shifting or falling off during installation or use, and ensuring the long-term stability of the sealing structure.

[0036] Specifically, such as Figure 6 As shown, a first limiting block 11 is fixedly connected to the inner wall of the positioning frame 5, and the surface of the first limiting block 11 is engaged with the inner wall of the first tube 1.

[0037] Specifically, such as Figure 6 As shown, a second limiting block 12 is fixedly connected to the inner wall of the positioning frame 5, and the surface of the second limiting block 12 is engaged with the inner wall of the second tube 3.

[0038] In this embodiment: by setting a first limiting block 11 and a second limiting block 12, the first limiting block 11 and the second limiting block 12 are respectively fixed to the inner wall of the positioning frame 5, so that the positioning frame 5 can drive the first limiting block 11 and the second limiting block 12 to be respectively snapped into the inner wall of the first tube 1 and the second tube 3, which facilitates the completion of the initial connection and fixing work.

[0039] Specifically, such as Figure 6 As shown, the first reinforcing mechanism 2 includes a reinforcing block 201, a positioning block 202, and a fixing rod 203. The right side of the fixing rod 203 is fixedly connected to the left side of the positioning frame 5, and the left side of the fixing rod 203 is fixedly connected to the right side of the reinforcing block 201. The inner wall of the reinforcing block 201 is fixedly connected to the surface of the positioning block 202. The surface of the positioning block 202 is engaged with the inner wall of the first tube 1, and the inner wall of the reinforcing block 201 is in contact with the surface of the first tube 1.

[0040] Specifically, such as Figure 5 As shown, a base assembly 13 is provided at the bottom of the positioning frame 5. The surface of the base assembly 13 is engaged with the inner wall of the first tube 1, and the surface of the base assembly 13 is engaged with the inner wall of the second tube 3.

[0041] Specifically, such as Figure 5 As shown, the base assembly 13 is fixedly connected to the front and rear sides with a first mounting plate 14, and the positioning frame 5 is fixedly connected to the front and rear sides with a second mounting plate 15.

[0042] Specifically, such as Figure 5 As shown, a knob 16 is movably connected to the inner wall of the second mounting plate 15, and the surface of the knob 16 is threadedly connected to the inner wall of the first mounting plate 14.

[0043] In this embodiment: by setting a reinforcing block 201, a positioning block 202, and a fixing rod 203, the fixing rod 203 can provide stable support for the reinforcing block 201, making the reinforcing block 201 tightly fit against the surface of the first tube 1. The positioning block 202 can be engaged with the inner wall of the first tube 1 to further enhance the connection between the reinforcing block 201 and the first tube 1, thereby more efficiently strengthening the structure of the connecting end of the first tube 1 and effectively resisting external mechanical impact and compression. By setting a base assembly 13, and the base assembly 13 being engaged with the inner walls of both the first tube 1 and the second tube 3, It can provide support for the connection between the first tube body 1 and the second tube body 3 from the bottom of the tube body, further improving the load-bearing capacity and stability of the overall connection structure. By setting the first mounting plate 14 and the second mounting plate 15, the first mounting plate 14 is fixed to the base assembly 13 and the second mounting plate 15 is fixed to the positioning frame 5 during use. This makes it easy to rotate the second mounting plate 15 and the inner wall of the first mounting plate 14 by the knob 16, which makes it easy to restrict the position of the base assembly 13 and the positioning frame 5, and effectively improves the convenience of connecting the protective tube.

[0044] Working principle: During the use of the first tube 1, firstly, the protrusion 4 on the right side of the first tube 1 is aligned with the positioning groove 9 on the inner wall of the second tube 3 and inserted, so that the protrusion 4 and the second tube 3 are initially connected. At this time, the first sealing ring 7 on the inner wall of the protrusion 4 is tightly fitted with the inner wall of the second tube 3, and at the same time, the second sealing ring 8 on the inner wall of the first tube 1 is embedded in the sealing groove 10 on the inner wall of the second tube 3, forming a multiple sealing structure to prevent moisture and impurities from seeping in. Next, the positioning frame 5 is fitted onto the connection part between the first tube 1 and the second tube 3, so that the first limiting block 11 on the inner wall of the positioning frame 5 is engaged with the inner wall of the first tube 1 and the second limiting block 12 is engaged with the inner wall of the second tube 3, completing the initial fixation of the positioning frame 5. At this time, the first reinforcing mechanism 2 on the left side of the positioning frame 5 is engaged. The reinforcing block 201 supported by the fixing rod 203 fits tightly against the surface of the first pipe body 1. The positioning block 202 on the inner wall of the reinforcing block 201 engages with the inner wall of the first pipe body 1. The second reinforcing mechanism 6 on the right side of the positioning frame 5 engages with the inner wall of the second pipe body 3 simultaneously, thus strengthening the structure of the connection end of the first pipe body 1 and the second pipe body 3. Then, the base assembly 13 is installed from the bottom of the pipe body, so that the base assembly 13 engages with the inner walls of the first pipe body 1 and the second pipe body 3. Then, the knob 16 is used to rotate the inner walls of the second mounting plate 15 and the first mounting plate 14, thereby fixing the base assembly 13 and the positioning frame 5 into one piece, forming support for the connection part from the bottom, and finally completing the sealed connection and structural reinforcement of the first pipe body 1 and the second pipe body 3, providing stable protection for subsequent cable laying.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
