Description

Technical Field

[0001] The utility model relates to a ring current resistant hot-dip plastic steel pipe, belonging to the technical field of pipe fittings. Background Art

[0002] Hot-dip plastic steel pipe is also called hot-dip plastic protective pipe. It is widely used in cable protection in the fields of electricity, communication, etc. due to its high mechanical strength, strong pressure bearing capacity and good flame retardancy.

[0003] Existing hot-dip plastic steel pipes are usually fastened and connected by flanges, bolts, etc. when assembled together. This traditional connection method is inconvenient to operate, which greatly reduces the disassembly and assembly efficiency of workers when replacing and repairing the hot-dip plastic steel pipes.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a hot-dip plastic steel pipe that is resistant to ring current. It solves the problem that the existing hot-dip plastic steel pipes are usually fastened and connected by flanges, bolts, etc. when assembled to each other. This traditional connection method is inconvenient to operate, which leads to a greatly reduced disassembly and assembly efficiency when the staff replaces and repairs the hot-dip plastic steel pipe.

[0006] The technical problem to be solved by the utility model is achieved by adopting the following technical scheme: a kind of anti-ring current hot-dip plastic steel pipe, comprising a plurality of tube bodies connected to each other, adjacent tube bodies are connected by a connecting structure, the connecting structure comprises a connecting sleeve arranged on the outer peripheral wall of one end of the tube body, both ends of the outer peripheral wall of the connecting sleeve are provided with clamping blocks, an annular sleeve is arranged on the outer peripheral wall of the other end of the tube body, a clamping groove for the connecting sleeve to be clamped is formed between the annular sleeve and the outer wall of the tube body, an annular groove is opened on the outer peripheral wall of the annular sleeve along a circle in the circumferential direction, an annular block is rotatably connected in the annular groove, slots 1 for the clamping block to be clamped are opened on both sides of one end of the annular sleeve, the slot 1 does not penetrate the annular block, and slots 2 for the clamping block to be clamped are opened on both sides of one end of the annular block.

[0007] By adopting the above technical scheme and setting a connecting structure, when two pipe bodies are connected to each other, it is only necessary to align one end of one pipe body with the other pipe body first, and then insert the connecting sleeve into the slot, and make the clamping block insert and pass through slot one to enter slot two. At this time, it is only necessary to rotate the first pipe body to make the clamping block drive the annular block to rotate, so that slot one and slot two are no longer aligned, and then under the limit of the annular groove, the clamping block cannot be separated from the annular groove, so that the connection between the two pipe bodies is not easy to be separated, the connection operation is convenient, and the disassembly and assembly efficiency of the staff when replacing and repairing the hot-dip plastic steel pipe is improved.

[0008] The utility model is further configured as follows: connecting plates are also provided on both sides of the outer peripheral wall of the annular sleeve, the outer diameter of the clamping block is larger than the inner diameter of the connecting plate, one end of the annular block is provided with a limiting structure for abutting against one end of the connecting plate to limit the rotation of the annular block, the limiting structure includes a limiting block that slides radially inside one end of the annular block, one end of the annular block is provided with a sliding groove for the limiting block to be clamped, and an elastic member is fixed between the limiting block and the inner bottom wall of the sliding groove.

[0009] By adopting the above technical scheme, when the card block is not inserted into the second slot, the limit block is located inside the slide groove and one end abuts against the inner wall of the connecting plate and the elastic member is in a compressed state. When the card block drives the annular block to rotate, the limit block can slide on the inner wall of the connecting plate until it is out of the limit of the connecting plate. At this time, the elastic member is no longer squeezed by the connecting plate, so it can restore its original state and drive the limit block to pop out outward to abut against the outer wall of the side end of the connecting plate. At this time, the card block also abuts against the end of the other connecting plate. Through the abutment and limitation of the limit block by one connecting plate and the abutment and limitation of the card block by the other connecting plate, after the annular block pulls out the limit block, the annular block cannot rotate, thereby making the connection between the tube body and the tube body more stable.

[0010] The utility model is further configured as follows: a connection groove for the limit block to be inserted is provided on the surface of the connection plate.

[0011] By adopting the above technical solution, when the limit block is inside the connecting plate, the limit block can be located inside the connecting groove under the elastic force of the elastic member, and the connecting groove limits the limit block, making it difficult for the annular block to rotate.

[0012] The utility model is further configured as follows: a limiting plane is provided at one end of the limiting block facing away from the rotation direction, and a guiding inclined plane is provided at the other end along the inclined direction.

[0013] By adopting the above technical solution, the setting of the limiting plane enables the limiting plane to abut against the side end of the connecting plate after the limiting block is pulled out of the connecting plate, thereby ensuring that the limiting block cannot retreat. The setting of the guiding inclined surface enables the limiting block to easily detach from the connecting groove under the action of the guiding inclined surface when the annular block rotates.

[0014] The beneficial effect of the utility model is that by setting up the connecting structure, when two pipe bodies are connected to each other, it is only necessary to align one end of one pipe body with the other pipe body first, and then insert the connecting sleeve into the slot, and make the clamping block insert and pass through slot one to enter slot two. At this time, it is only necessary to rotate the first pipe body to make the clamping block drive the annular block to rotate, so that slot one and slot two are no longer aligned, and then under the limit of the annular groove, the clamping block cannot be separated from the annular groove, so that the connection between the two pipe bodies is not easy to be separated, the connection operation is convenient, and the disassembly and assembly efficiency of the staff when replacing and repairing the hot-dip plastic steel pipe is improved.

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below in conjunction with specific illustrations.

[0021] like Figure 1 and Figure 3 As shown, a ring current resistant hot-dip plastic steel pipe comprises a plurality of pipe bodies 1 connected to each other, and adjacent pipe bodies 1 are connected via a connecting structure.

[0022] The connection structure comprises a connection sleeve 2 arranged on the outer peripheral wall of one end of the tube body 1, and clamping blocks 3 are arranged on both ends of the outer peripheral wall of the connection sleeve 2.

[0023] An annular sleeve 4 is provided on the outer circumferential wall of the other end of the tube body 1, and a card groove 5 for the connecting sleeve 2 to be inserted is formed between the annular sleeve 4 and the outer wall of the tube body 1, an annular groove 6 is opened on the outer circumferential wall of the annular sleeve 4 along the circumferential direction, and an annular block 7 is rotatably connected in the annular groove 6, and slots 8 for the card block 3 to be inserted are opened on both sides of one end of the annular sleeve 4, and the slots 8 do not penetrate the annular block 7, and slots 9 for the card block 3 to be inserted are opened on both sides of one end of the annular block 7.

[0024] By setting up the connecting structure, when the two pipe bodies 1 are connected to each other, it is only necessary to align one end of one pipe body 1 with the other pipe body 1, and then insert the connecting sleeve 2 into the slot 5, and make the clamping block 3 insert and pass through the slot one 8 and enter the slot two 9. At this time, it is only necessary to rotate the first pipe body 1, so that the clamping block 3 can drive the annular block 7 to rotate, so that the slot one 8 and the slot two 9 are no longer aligned, and then under the limit of the annular groove 6, the clamping block 3 cannot be separated from the annular groove 6, so that the connection between the two pipe bodies 1 is not easy to be separated, the connection operation is convenient, and the disassembly and assembly efficiency of the staff when replacing and repairing the hot-dip plastic steel pipe is improved.

[0025] like Figure 2 and Figure 3 As shown, connecting plates 10 are further provided on both sides of the outer peripheral wall of the annular sleeve 4 , and the outer diameter of the clamping block 3 is larger than the inner diameter of the connecting plates 10 .

[0026] It should be noted that after the annular groove 6 is formed on the annular sleeve 4 , the two sections of the annular sleeve 4 divided by the annular groove 6 are connected by two connecting plates 10 .

[0027] A limiting structure is provided at one end of the annular block 7 for abutting against one end of the connecting plate 10 to limit the rotation of the annular block 7. The limiting structure includes a limiting block 11 which slides radially inside one end of the annular block 7. A sliding groove 12 is provided at one end of the annular block 7 for the limiting block 11 to be inserted into. An elastic member 13 is fixed between the limiting block 11 and the inner bottom wall of the sliding groove 12.

[0028] When the card block 3 is not inserted into the slot 2 9, the limit block 11 is located inside the slide groove 12 and one end abuts against the inner wall of the connecting plate 10 and the elastic member 13 is in a compressed state. When the card block 3 drives the annular block 7 to rotate, the limit block 11 can slide on the inner wall of the connecting plate 10 until it is out of the limit of the connecting plate 10. At this time, the elastic member 13 is no longer squeezed by the connecting plate 10, so that it can restore its original state and drive the limit block 11 to pop out outward so as to abut against the outer wall of the side end of the connecting plate 10. At this time, the card block 3 also abuts against the end of the other connecting plate 10. Through the abutment and limitation of one connecting plate 10 on the limit block 11 and the abutment and limitation of the other connecting plate 10 on the card block 3, after the annular block 7 pulls out the limit block 11, the annular block 7 cannot rotate, thereby making the connection between the pipe body 1 and the pipe body 1 more stable.

[0029] like Figure 3 As shown, a connection groove 14 is provided on the surface of the connection plate 10 for the stop block 11 to be inserted into. When the stop block 11 is inside the connection plate 10, the stop block 11 can be located inside the connection groove 14 under the elastic force of the elastic member 13, and the stop block 11 is limited by the connection groove 14, so that the annular block 7 is not easy to rotate.

[0030] like Figure 3As shown, the limit block 11 has a limit plane 15 at one end facing away from the rotation direction, and a guide slope 16 at the other end along the tilting direction. The limit plane 15 allows the limit plane 15 to abut against the side end of the connecting plate 10 after the limit block 11 is pulled out of the connecting plate 10, thereby ensuring that the limit block 11 cannot retreat, and the guide slope 16 allows the limit block 11 to easily detach from the connecting groove 14 under the action of the guide slope 16 when the annular block 7 rotates.

[0031] In addition, the inner wall and the outer wall of the tube body 1 are coated with insulating coating, thereby greatly improving the anti-circulating current effect of the tube body 1.

[0032] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of protection claimed by the utility model. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
