Description

Technical Field

[0001] This utility model relates to the field of cable protection pipe technology, and in particular to a joint device for cable protection pipe. Background Technology

[0002] Cable protection pipes, also known as cable conduits, power cable conduits, cement cable conduits, power ducts, and power cable protection pipes, are mainly installed at the intersections of communication cables and power lines to prevent short circuits caused by power line breaks, which could lead to energization of communication cables and steel wire ropes. This protects cables, switches, circuit boards, and even the entire device from being burned out, and also provides some isolation against magnetic field interference from power lines.

[0003] When laying cables, the connection points of adjacent cable protection pipes need to be connected. Traditional joint devices for fixing cable protection pipes are relatively weak and are prone to falling off. Furthermore, the connection effect will be affected by long-term erosion from external factors such as rainwater. Utility Model Content

[0004] The purpose of this utility model is to address the deficiencies of the existing technology by providing a connector device for cable protection pipes, thereby solving the problems mentioned in the background art.

[0005] A connector device for a cable protection pipe includes a first pipe fitting and a second pipe fitting connected by a connecting assembly. The narrow end of the second pipe fitting can be inserted into the tail end of the first pipe fitting. The first pipe fitting has an annular groove, and multiple receiving grooves and placement grooves are staggered around the annular groove. The connecting assembly includes a ring stop, a screw, a nut, a positioning block, a hexagonal bolt, and a nut. The ring stop is slidably inserted into a fixing ring on the outer wall of the first pipe fitting. The screw consists of multiple screws that are installed around the step of the second pipe fitting and can be inserted into the receiving groove on the outer wall of the first pipe fitting. It can also be locked onto the first pipe fitting by the nut. When the ring stop moves to cover the annular groove, the positioning block can be inserted from the rectangular groove of the ring stop and penetrate the placement groove into the slot on the outer wall of the second pipe fitting. The hexagonal bolt is inserted into the through hole on the positioning block, and its bottom can be connected to the threaded hole at the slot. The nut is rotatably installed at the upper end of the through hole of the positioning block.

[0006] By adopting the above technical solution, two pipe fittings can be connected, and while ensuring a stable connection, external rainwater and other factors can be prevented from corroding the components on the connection assembly, thus extending its service life.

[0007] One side of the annular groove is also provided with an embedding groove, and when the annular stop covers the annular groove, one end of it can be inserted into the embedding groove.

[0008] By adopting the above technical solution, the components are shielded.

[0009] The length of the screw is set to be greater than the length of the receiving groove. After the screw passes through the receiving groove, its end can be embedded into the pipe fitting.

[0010] By adopting the above technical solution, it is possible to connect fitting one and fitting two.

[0011] Both the screw and the positioning block are configured in three sets.

[0012] By adopting the above technical solution, pipe fitting one and pipe fitting two are stably and fixedly connected.

[0013] When one end of the ring is inserted into the embedding groove, the end of the rectangular groove away from the embedding groove is tightly fitted with the fixed ring, and the length of the upper end plate of the positioning block is equal to the distance from the fixed ring to the embedding groove.

[0014] By adopting the above technical solution, a stable connection between fitting one and fitting two is ensured.

[0015] The beneficial effects of the joint device for the cable protection pipe of this utility model are:

[0016] Rotate the nut onto the screw rod. After the second end of the pipe fitting is fully inserted into the first pipe fitting, rotate the nut to lock the screw rod in the receiving groove. Push the ring stop to insert one end of the ring stop into the embedding groove, and then insert the positioning block from the rectangular groove into the placement groove until the bottom of the positioning block abuts against the slot of the second end of the pipe fitting. Insert the hexagonal bolt into the hole slot on the positioning block, rotate the hexagonal bolt to tighten the bottom of the hexagonal bolt into the threaded hole at the slot, and fix the positioning block. Then rotate the nut to install in the hole slot of the positioning block to close the hole slot. This connects the two pipe fittings, ensuring a stable connection while preventing external rainwater and other factors from corroding the components of the connection assembly, thus extending its service life.

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0022] Reference Figure 1-3 A connector device for a cable protection pipe includes a first pipe fitting 101 and a second pipe fitting 102 connected by a connecting assembly. The narrow end of the second pipe fitting 102 can be inserted into the tail end of the first pipe fitting 101. The first pipe fitting 101 has an annular groove 1012, and multiple receiving grooves 10122 and placement grooves 10123 are staggered around the annular groove 1012. The connecting assembly includes a ring stop 2, a screw 3, a nut 4, a positioning block 5, a hexagonal bolt 6, and a nut 7. The ring stop 2 is slidably inserted into a fixing ring 1011 on the outer wall of the first pipe fitting 101. The screw 3 has multiple surrounding rings. Installed at the step of pipe fitting 2 102, and can be inserted into the receiving groove 10122 opened on the outer wall of pipe fitting 101, and can be locked onto pipe fitting 101 by nut 4. When the ring stop 2 moves to cover the ring groove 1012, the positioning block 5 can be inserted from the rectangular groove 201 of the ring stop 2, and inserted through the placement groove 10123 into the slot 1021 opened on the outer wall of pipe fitting 2 102. The hex bolt 6 is inserted into the through hole on the positioning block 5, and its bottom can be connected to the threaded hole at the slot 1021. The nut 7 is rotatably installed at the upper end of the through hole of the positioning block 5.

[0023] During connection, insert the thin end of the second pipe fitting 102 into the inner ring of the first pipe fitting 101 and fit it. At this time, the screw 3 is inserted into the outer wall of the first pipe fitting 101 and is in the receiving groove 10122. Before the head of the second pipe fitting 102 is fully inserted into the inner ring of the first pipe fitting 101, rotate the nut 4 to install it on the screw 3. After the head of the second pipe fitting 102 is fully inserted into the first pipe fitting 101, rotate the nut 4 to lock the screw 3 in the receiving groove 10122.

[0024] Then push the ring stop 2 to insert one end of the ring stop 2 into the embedding groove 10121. At this time, the positioning block 5 can be inserted from the rectangular groove 201 into the placement groove 10123 until the bottom of the positioning block 5 abuts against the slot 1021 of the head of the pipe fitting 102. Then, the hex bolt 6 can be inserted into the hole groove on the positioning block 5. Rotate the hex bolt 6 to tighten the bottom of the hex bolt 6 into the threaded hole at the slot 1021, thereby fixing the positioning block 5. Then, rotate the nut 7 to install it into the hole groove of the positioning block 5 to close the hole groove.

[0025] This connects the two pipe fittings and ensures a stable connection while preventing external rainwater from corroding the components of the connection assembly, thus extending its service life.

[0026] One side of the annular groove 1012 is also provided with an embedding groove 10121. When the annular stop 2 covers the annular groove 1012, one end of it can be inserted into the embedding groove 10121. The length of the rectangular groove 201 is set to be slightly longer than the length of the lower end of the positioning block 5, so that after one end of the rectangular groove 201 is embedded in the embedding groove 10121, the positioning block 5 can just pass through the rectangular groove 201 and pass down through the placement groove 10123 to the card slot 1021.

[0027] The length of the screw 3 is set to be greater than the length of the receiving groove 10122. After the screw 3 passes through the receiving groove 10122, its end can be embedded into the pipe fitting 101. The screw 3 and the positioning block 5 are both set in three sets. Through the cooperation of the screw 3 and the positioning block 5, the pipe fitting 101 and the pipe fitting 2 102 can be stably connected to ensure its stability.

[0028] When one end of the ring stop 2 is inserted into the embedding groove 10121, the end of the rectangular groove 201 away from the embedding groove 10121 is tightly fitted with the fixing ring 1011, and the length of the upper end plate of the positioning block 5 is equal to the distance from the fixing ring 1011 to the embedding groove 10121; the ring stop 2 can cover the screw 3, effectively preventing rainwater from corroding the parts, and the nut 7 also protects the hexagonal bolt 6, preventing rainwater from entering through the hole groove of the positioning block 5.

[0029] The tail end of the cable protection pipe 1 is set as the structure of fitting 101, and the head end of the cable protection pipe 1 is set as the structure of fitting 102. When connecting, the thin end of the head of fitting 102 is inserted into the inner ring of fitting 101 and fits. At this time, the screw 3 is inserted into the outer wall of fitting 101 and is in the receiving groove 10122. Before the head of fitting 102 is fully inserted into the inner ring of fitting 101, the nut 4 is rotated and installed on the screw 3. After the head of fitting 102 is fully inserted into fitting 101, the nut 4 is rotated to lock the screw 3 in the receiving groove 10122.

[0030] Then push the ring stop 2 to insert one end of the ring stop 2 into the embedding groove 10121. At this time, the positioning block 5 can be inserted from the rectangular groove 201 into the placement groove 10123 until the bottom of the positioning block 5 abuts against the slot 1021 of the head of the pipe fitting 102. Then, the hex bolt 6 can be inserted into the hole groove on the positioning block 5. Rotate the hex bolt 6 to tighten the bottom of the hex bolt 6 into the threaded hole at the slot 1021, thereby fixing the positioning block 5. Then, rotate the nut 7 to install it into the hole groove of the positioning block 5 to close the hole groove.

[0031] This connects the two pipe fittings, ensuring a stable connection while preventing external rainwater and other factors from corroding the components of the connection assembly, thus extending its service life.

[0032] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
