Description

Technical Field

[0001] The utility model relates to the field of cabin through-pieces, in particular to a cabin through-piece used for non-metallic pipes. Background Art

[0002] Cabin through fittings are installed on the bulkhead plate to allow cables to pass through, playing a connecting role, protecting the cables and pipes in the cabin from extrusion and wear, closing the bulkhead openings, and enhancing the strength of the bulkhead openings. Most of the pipe cabin fittings are connected by flanges. For non-metallic pipes, their pressure resistance is poor. Passing through the cabin body through the cabin through fittings has strong protection capabilities. The sealing ability between the cabin through fittings and the cabin body is required to be high to prevent the non-metallic pipes inside the cabin through fittings from corroding too quickly.

[0003] Existing cabin passages for non-metallic pipes, for example, a sealed cabin passage for ships proposed in patent application number "CN202123354089.6", has a cabin passage body, a base, a cylinder, abutment plates and other structures. The cylinder and the abutment plates are arranged to squeeze the sealing plate, so that the sealing plate is more tightly connected to the control cabin, thereby improving the sealing performance.

[0004] However, it only uses a cylinder and abutment plate to squeeze and seal the sealing plate, and the sealing effect is poor. When the cabin body is damaged by impact and grooves appear, there is a gap between the sealing plate and the cabin body, and the sealing performance is reduced. Therefore, a cabin access part for non-metallic pipes is proposed. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] A through-hole for non-metallic pipes, such as Figure 1-Figure 5 As shown, it includes a tube body 1, one end of which is fixedly connected to a flange 2, and the other end of the tube body 1 is inserted into the cabin body, the side wall of the tube body 1 is sleeved with an inner sealing ring 3 and a screw ring 4, the side wall of the tube body 1 is provided with a thread 5 for connecting with the inner wall thread 5 of the screw ring 4, the inner sealing ring 3 is clamped between the screw ring 4 and the cabin body, the outer wall of the screw ring 4 is fixedly connected to an outer sealing ring 6, and the end of the outer sealing ring 6 is sealed with the cabin body.

[0025] By inserting the tube body 1 on the cabin body and rotating the screw ring 4, the inner sealing ring 3 is tightly against the cabin body, and the inner sealing ring 3 forms an inner seal between the cabin body and the tube body 1. While the screw ring 4 rotates and squeezes the inner sealing ring 3, it drives the outer sealing ring 6 to squeeze the cabin body wall, so that an outer seal is formed between the cabin body, the screw ring 4 and the outer sealing ring 6. The simultaneous internal and external sealing method effectively prevents the cabin body from having grooves that reduce the sealing performance. The sealing effect is better and the protective performance of non-metallic pipes is improved.

[0026] The side wall of the spiral ring 4 is fixedly connected with multiple groups of fixing blocks 7, which are arranged in a circular array, and one side of the multiple groups of fixing blocks 7 is in contact with the side wall of the tube body 1. The side wall of the spiral ring 4 is plugged with multiple groups of locking components, and the ends of the multiple groups of locking components are plugged into and matched with the side wall of the cabin body.

[0027] like Figure 1-Figure 4 As shown, multiple groups of fixing blocks 7 can facilitate driving the screw ring 4 to rotate, but the fixing blocks 7 are not connected to the side wall of the tube body 1. The locking assembly prevents the screw ring 4 from rotating out of the cabin, thereby increasing the fixing ability of the screw ring 4.

[0028] The locking assembly includes a locking rod 9, a socket is penetrated on the screw ring 4, the locking rod 9 is plugged into the socket, and the end of the locking rod 9 is plugged into the cabin body, a fixing plate 17 is fixedly connected to the side wall of the locking rod 9, the fixing plate 17 is abutted against the side of the screw ring 4 close to the flange 2, an extension plate 10 is fixedly connected to one end of the fixing plate 17, and the extension plate 10 is snap-fitted into the fixing block 7.

[0029] like Figure 1-Figure 4 As shown, after the screw ring 4 is installed, the locking rod 9 is inserted into the cabin through the jack to prevent the screw ring 4 from rotating. The fixing plate 17 is slid and rotated to allow the extension plate 10 to be clamped on the end of the fixing block 7 to facilitate the rotation of the screw ring 4.

[0030] A plurality of locking rods 9 are provided with a slide groove 11 therein, and a plurality of connecting columns 12 are fixedly connected to one side of the flange 2 close to the screw ring 4. The plurality of connecting columns 12 are arranged in a circular array, and the plurality of connecting columns 12 are respectively plugged into and matched with the plurality of slide grooves 11.

[0031] like Figure 4 As shown, the connecting column 12 limits the moving path of the locking rod 9 to prevent the locking rod 9 from being separated from the periphery of the tube body 1 .

[0032] The side walls of the plurality of groups of connecting columns 12 are sleeved with compression springs 13 , one end of the compression spring 13 is fixedly connected to the side wall of the flange 2 , and the other end is in contact with one side of the fixing plate 17 .

[0033] like Figure 4 As shown, the compression spring 13 is always in a compressed state, and will always squeeze the fixing plate 17, so that the locking rod 9 is firmly inserted into the cabin body and the screw ring 4, and the locking rod 9 is slid and rotated to make the extension plate 10 engage with the fixing block 7. At this time, the end of the locking rod 9 is separated from the screw ring 4, and the screw ring 4 is in an unlocked state and can be rotated to a certain angle. The distance between adjacent fixing blocks 7 can be set to be smaller than the width of the extension plate 10, so that the extension plate 10 is always engaged with the end of the fixing block 7 when the screw ring 4 rotates, thereby increasing the rotation angle range of the screw ring 4.

[0034] The side wall of the tube body 1 is provided with a plurality of installation cavities 14, which are arranged in a circular array. Compression springs 15 are fixedly connected inside the plurality of installation cavities 14, and the ends of the compression springs 15 are fixedly connected to limit blocks 16. The side walls of the limit blocks 16 are slidably connected to the inner walls of the installation cavities 14, and the limit blocks 16 are snap-fitted with a side of the cabin away from the inner sealing ring 3.

[0035] like Figure 2 and Figure 5 As shown, the compression spring 15 is always in a compressed state, squeezing the end of the limit block 16 to pop out of the installation cavity 14. The limit block 16 is a right triangle or a right trapezoid, which will not hinder the insertion of the pipe body 1 into the cabin body, and is clamped on one side of the cabin body to increase the installation stability of the pipe cabin component.

[0036] The working principle of a through-tank fitting for non-metallic pipes provided by the utility model is as follows:

[0037] By inserting the tube body 1 on the cabin body and rotating the screw ring 4, the inner sealing ring 3 is tightly against the cabin body, and the inner sealing ring 3 forms an inner seal between the cabin body and the tube body 1. While the screw ring 4 rotates and squeezes the inner sealing ring 3, it drives the outer sealing ring 6 to squeeze the cabin body wall, so that an outer seal is formed between the cabin body, the screw ring 4 and the outer sealing ring 6. The simultaneous internal and external sealing method effectively prevents the cabin body from having grooves that reduce the sealing performance. The sealing effect is better and the protective performance of non-metallic pipes is improved.

[0038] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
