Description
Technical Field
[0001] The utility model relates to the technical field of ships, and particularly relates to a marine polyethylene pipe fitting convenient for docking. Background Technique
[0002] A ship is a vessel that utilizes the buoyancy of water and relies on human power, sails, or engines. Among the components used in ships, polyethylene pipe fittings are of utmost importance and are commonly used for fluid transportation on ships, such as fuel, lubricating oil, hydraulic oil, etc.
[0003] For example, the utility model with the publication number CN210831025U discloses a polyethylene pipe fitting for water supply, which includes a pipe body and a fixed head. The utility model is provided with a connector. The connector composed of a main body, an elastic connecting piece, a fastening plate, and an anti-corrosion layer can tightly fit the pipeline in all directions. The reset spring and the spiral spring arranged in the elastic connecting piece can control the fastening plate to contract or extend, so as to ensure that the fastening plate can always fit the pipeline, effectively avoiding the pipeline from falling off from the connection end, and effectively improving the stability of the utility model. This connector can be applicable to pipelines of various specifications. The fastening plate in the connector can be tightened or expanded under the action of the reset spring and the spiral spring, so that the inner diameter of the connector can be adjusted, and pipelines of different specifications can be connected, effectively improving the versatility and practicality of the utility model. However, when this polyethylene pipe fitting is in use, there are still other deficiencies. First of all, the docking of the polyethylene pipe fitting is adjusted by tightening or expanding through the reset spring and the spiral spring. Since the reset spring and the spiral spring will become lower after long-term use, the effect of connecting pipelines of different specifications is unstable, and the sealing effect of docking is reduced. At the same time, it is impossible to limit and fix marine polyethylene pipe bodies with different diameters, increasing the labor of workers in subsequent docking and installation. Therefore, there are still certain deficiencies when using this device. Content of the Utility Model

[0013] Further, clamping grooves are opened on the inner walls of the upper and lower sides of the second polyethylene pipe body. The clamping grooves are matched with the sealing gaskets.
[0014] Compared with the prior art, the beneficial effects of the utility model are:
[0015] The marine polyethylene pipe fitting facilitating docking quickly docks the marine polyethylene pipe body by setting a threaded rod, and sets a first limiting sleeve and a second limiting sleeve, which can limit and fix the marine polyethylene pipe bodies with different diameters, improve the efficiency of subsequent docking, and sets an inner pipe to increase the sealing effect of the docking of the marine polyethylene pipe body. The specific content is as follows:
[0016] 1. A threaded rod is set. The output shaft of the motor body drives the threaded rod to rotate, so that the threaded rod drives each threaded sleeve to move through the first limiting sleeve connected by the first support plate, the first telescopic cylinder body and the first mounting bracket. Thus, each first limiting sleeve drives the first polyethylene pipe body and the second polyethylene pipe body fixed inside the second limiting sleeve to move closer. During the movement of each second limiting sleeve, it drives the movable sleeve connected by the second mounting bracket through the second telescopic cylinder body and the second support plate to move on the guide rod, increasing the stability of the movement of the first polyethylene pipe body and the second polyethylene pipe body, and making the first polyethylene pipe body and the second polyethylene pipe body approach each other for docking, so as to quickly dock the marine polyethylene pipe body;
[0017] Further, a first limiting sleeve and a second limiting sleeve are set. By starting each first telescopic cylinder body and the second telescopic cylinder body through an external control board, the output ends of each first telescopic cylinder body and the second telescopic cylinder body drive the first limiting sleeve and the second limiting sleeve to approach each other. Thus, the anti-slip pads connected to each first limiting sleeve and the second limiting sleeve are attached to the outer walls of the corresponding first polyethylene pipe body and the second polyethylene pipe body. Then, manually pass each fastening bolt through the through holes through the first connecting plate and the second connecting plate, so as to limit and fix the marine polyethylene pipe bodies with different diameters, and improve the efficiency of subsequent docking;
[0018] 2. An inner pipe is set. During the process of the mutual movement and docking of the first polyethylene pipe body and the second polyethylene pipe body, the first polyethylene pipe body drives the inner pipe to insert into the second polyethylene pipe body. Thus, each sealing pad connected to the inner pipe is clamped into the card slot, increasing the sealing effect of the docking of the marine polyethylene pipe body;
[0019] 3. Positioning bolts are set. By manually pulling out each positioning bolt from each first mounting bracket and the second mounting bracket, each first limiting sleeve and the second limiting sleeve drive the first polyethylene pipe body and the second polyethylene pipe body to separate from the first mounting bracket and the second mounting bracket, so that the connected marine polyethylene pipe body can be disassembled.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0029] Please refer to Figures 1-7 , the present utility model provides the following technical solutions:
[0030] Embodiment 1: To solve the problem that when polyethylene pipe fittings in the market are in use, the docking of polyethylene pipe fittings is adjusted by tightening or expanding through a return spring and a spiral spring. Since the return spring and the spiral spring will become shorter after long-term use, the effect of connecting pipes of different specifications is unstable, and the docking sealing effect is reduced. At the same time, it is impossible to limit and fix marine polyethylene pipe bodies of different diameters, increasing the labor of workers in subsequent docking and installation. Reference can be made to the attached Figure 1 - attachedFigure 5, including a base 1, a first polyethylene pipe body 20 and a second polyethylene pipe body 23. The top of the base 1 is connected with a motor body 2 through a first mounting plate. The output shaft of the motor body 2 is fixedly connected with a threaded rod 3 through a coupling. Two threaded sleeves 4 are sleeved on the outer wall of the threaded rod 3. The top of the threaded sleeve 4 is fixedly installed with a first support plate 5. The front of the first support plate 5 is provided with a first telescopic cylinder body 6. The output end of the first telescopic cylinder body 6 is fixedly connected with a first mounting bracket 7; The top of the base 1 is fixedly installed with a guide rod 11 through a second mounting plate. Two movable sleeves 12 are sleeved on the outer wall of the guide rod 11. The top of the movable sleeve 12 is fixedly installed with a second support plate 13. The back of the second support plate 13 is provided with a second telescopic cylinder body 14. The output end of the second telescopic cylinder body 14 is fixedly connected with a second mounting bracket 15. The front of the second mounting bracket 15 is fixedly installed with a second limiting sleeve 16; First connecting plates 10 are fixedly installed on the upper and lower sides of the first limiting sleeve 9. Second connecting plates 17 are fixedly installed on the upper and lower sides of the second limiting sleeve 16. Fastening bolts 18 penetrate through the interiors of the first connecting plates 10 and the second connecting plates 17. The fastening bolts 18 are detachably connected with the first connecting plates 10 and the second connecting plates 17 through through holes. Anti-slip pads 19 are fixedly connected to the interiors of the first limiting sleeve 9 and the second limiting sleeve 16. The anti-slip pads 19 are arranged in an arc shape. The first limiting sleeve 9 is driven by the first telescopic cylinder body 6. The number of the first limiting sleeve 9 and the second limiting sleeve 16 is two.The first polyethylene pipe body 20 and the second polyethylene pipe body 23 to be installed are manually placed by the staff between the corresponding first limiting sleeve 9 and the second limiting sleeve 16 respectively. According to the diameters of the first polyethylene pipe body 20 and the second polyethylene pipe body 23, each first telescopic cylinder body 6 and the second telescopic cylinder body 14 are started through an external control board, so that the output ends of each first telescopic cylinder body 6 and the second telescopic cylinder body 14 drive the first limiting sleeve 9 and the second limiting sleeve 16 to approach each other. Thus, the anti-slip pads 19 connected to each first limiting sleeve 9 and the second limiting sleeve 16 are attached to the outer walls of the corresponding first polyethylene pipe body 20 and the second polyethylene pipe body 23. Then, each fastening bolt 18 is manually passed through the through holes through the first connecting plate 10 and the second connecting plate 17, so as to limit and fix the marine polyethylene pipe bodies with different diameters, improve the efficiency of subsequent docking, and cooperate with the external control board to start the motor body 2. The output shaft of the motor body 2 drives the threaded rod 3 to rotate, and the threaded rod 3 drives each threaded sleeve 4 to move through the first support plate 5, the first telescopic cylinder body 6 and the first limiting sleeve 9 connected to the first mounting frame 7. Thus, each first limiting sleeve 9 drives the first polyethylene pipe body 20 and the second polyethylene pipe body 23 fixed in the second limiting sleeve 16 to move closer. During the movement of each second limiting sleeve 16, the second mounting frame 15 is driven to move on the guide rod 11 through the movable sleeve 12 connected to the second telescopic cylinder body 14 and the second support plate 13, increasing the stability of the movement of the first polyethylene pipe body 20 and the second polyethylene pipe body 23, and making the first polyethylene pipe body 20 and the second polyethylene pipe body 23 approach each other for docking, so as to quickly dock the marine polyethylene pipe bodies.
[0031] Embodiment 2: To improve the sealing effect of the docking of the marine polyethylene pipe bodies, reference can be made to the attached Figure 1 and the attached Figure 4 -attached Figure 7 , a first polyethylene pipe body 20 is installed inside the second limiting sleeve 16 and the first limiting sleeve 9. One side of the first polyethylene pipe body 20 is fixedly connected with an inner pipe 21, and sealing gaskets 22 are fixedly installed on the upper and lower sides of the inner pipe 21. Card slots 24 are formed in the inner walls of the upper and lower sides of the second polyethylene pipe body 23, and the card slots 24 are matched with the sealing gaskets 22. During the process of the mutual movement and docking of the first polyethylene pipe body 20 and the second polyethylene pipe body 23, the first polyethylene pipe body 20 drives the inner pipe 21 to insert into the second polyethylene pipe body 23. Thus, the sealing gaskets 22 connected to the inner pipe 21 are snapped into the card slots 24, increasing the sealing effect of the docking of the marine polyethylene pipe bodies.
[0032] Embodiment 3: In order to disassemble the connected marine polyethylene pipe bodies, reference can be made to the attached Figure 1 -attached Figure 5, four positioning bolts 8 penetrate through the interior of the upper and lower sides of the first mounting bracket 7, and a first limiting sleeve 9 is fixedly installed at the rear of the first mounting bracket 7; four threaded holes are provided on one side of each of the first limiting sleeve 9 and the second limiting sleeve 16, and the positioning bolts 8 are threadedly connected to the threaded holes and the first limiting sleeve 9. By manually pulling out each positioning bolt 8 from each of the first mounting bracket 7 and the second mounting bracket 15, each first limiting sleeve 9 and the second limiting sleeve 16 drive the first polyethylene pipe body 20 and the second polyethylene pipe body 23 to be separated from the first mounting bracket 7 and the second mounting bracket 15, so that the connected marine polyethylene pipe body can be disassembled.
