Description

Technical Field

[0001] This application relates to the field of plastic hose technology, and in particular to a novel plastic hose. Background Technology

[0002] Plastic hoses are flexible tubes made of thermoplastic plastics, typically used for transporting drinking water, gases, chemicals, etc. They are generally made from plastic resins (such as polyester) with added stabilizers, lubricants, and plasticizers, processed through a specific extrusion process in a tube-making machine. Depending on the specific material, plastic hoses can be divided into various types, such as PVC hoses, PE hoses, and TPU hoses. Among them, PVC hoses are widely used in many fields due to their light weight, excellent low-temperature resistance, and good weather resistance.

[0003] Currently, most common plastic hoses on the market are just a single pipe fitting. The plastic hose is directly exposed to the outside world, which makes it easy for the hose to be directly subjected to external friction and collision, resulting in wear and scratches, damage to the hose, and a reduced service life. Utility Model Content

[0004] In order to solve the problems mentioned in the background art, this application provides a novel plastic hose.

[0005] This application provides a novel plastic hose, which adopts the following technical solution: a novel plastic hose, including a first protective tube, a second protective tube is provided at the lower end of the first protective tube, the first protective tube and the second protective tube cooperate with each other to form a protective sleeve, and positioning structures are provided on both sides of the protective sleeve.

[0006] The positioning structure includes a slot, a connecting rod, a mounting hole, a connecting block, an anti-slip pad, a positioning plate, a positioning rod, and a positioning hole. The first protective tube and the second protective tube are fitted together. Two positioning plates are provided, and the side walls of the two positioning plates are fitted together. The slot is opened on the upper surface of the positioning plate connected to the first protective tube. Multiple positioning blocks are fixedly connected at intervals on the lower surface of the first protective tube, and multiple positioning grooves are opened at intervals on the upper surface of the second protective tube.

[0007] The above solution utilizes the first and second protective tubes in conjunction to clamp and protect the plastic hose, preventing it from being worn.

[0008] Optionally, the first and second protective tubes are provided with clamps inside, the clamps are provided with locking blocks on their surfaces, and a hose body is installed between the first and second protective tubes.

[0009] The above solution utilizes the locking block to engage with the groove on the outside of the plastic hose, effectively positioning the plastic hose when it is installed between the first and second protective tubes, thus preventing it from becoming loose.

[0010] Optionally, the hose body is provided with a partition layer, a tensile layer, a metal wire mesh, a buffer layer and an outer layer from the inside out. The outer layer has multiple grooves spaced apart on its outer side. The locking block cooperates with the grooves. The partition layer is made of cross-linked polyethylene, the tensile layer is made of nylon, and the buffer layer is made of polyurethane.

[0011] The above method allows the plastic hose to be bent, and with the help of the wire mesh, the strength of the plastic hose can be improved.

[0012] Optionally, the positioning holes are formed at the four corners of the upper surface of one of the positioning plates, the positioning rod is fixedly connected to the four corners of the lower surface of the other positioning plate, an installation block is provided inside the slot, the lower surface of the installation block is fixedly connected to the upper end of the connecting rod, and the side wall of the connecting block is fixedly connected to the side wall of the connecting rod.

[0013] The above scheme utilizes the positioning hole and positioning block to cooperate, and the positioning block and positioning groove to cooperate, which facilitates the positioning and installation of the first and second protective tubes and avoids misalignment after installation.

[0014] Optionally, the upper surface of the anti-slip pad is fixedly connected to the lower surface of the connecting block, the mounting hole is opened through the middle of the connecting block and passes through the middle of the anti-slip pad, and the slot is opened on the upper surface of the positioning plate fixedly connected to the side wall of the first protective tube.

[0015] The above solution utilizes the mounting block and the slot to engage, and the connecting rod and the connecting block to engage, allowing the first protective tube to be pulled down, thus positioning the plastic hose and the protective tube.

[0016] Optionally, the groove extends through the outer side of the outer layer to the inside, and the outer side of the hose body fits against the inner wall of the clamp.

[0017] The above solution involves creating a groove inside the outer layer, which facilitates the engagement of the locking block with the groove. This allows the hose body to remain stable inside the two protective tubes after the first and second protective tubes clamp it, preventing misalignment.

[0018] Optionally, the outer part of the positioning block mates with the inner part of the positioning groove, and the outer part of the positioning rod mates with the inner part of the positioning hole.

[0019] The above scheme facilitates the installation of the first and second protective pipes.

[0020] Optionally, the reinforcing ribs inside the first and second protective tubes are arranged in a cross pattern, with the reinforcing ribs arranged laterally and longitudinally, and fixedly connected to the side wall of the clamp.

[0021] The above scheme facilitates the improvement of the strength of the first and second protective tubes and makes it easier to support them.

[0022] In summary, this application includes the following beneficial technical effects:

[0023] 1. This utility model uses a combination of a first protective tube, a second protective tube, a positioning plate, a positioning rod, a positioning hole, a positioning block, and a positioning groove. The first and second protective tubes work together, and the positioning plate, positioning rod, positioning hole, positioning block, and positioning groove are used for positioning. This allows the first and second protective tubes to be accurately installed on the outside of the hose body. Moreover, the first and second protective tubes can protect the hose body, prevent damage to the hose body, and improve its service life.

[0024] 2. By setting an outer layer, a buffer layer, a metal wire mesh, a tensile layer, and a partition layer, this utility model can improve the strength of the hose body, so that the hose body will not be damaged during bending, and the buffer layer can achieve a better cushioning effect.

[0031] This application discloses a novel plastic hose.

[0032] Please see Figure 1 A novel plastic hose includes a first protective tube 1, and a second protective tube 4 is provided at the lower end of the first protective tube 1. The first protective tube 1 and the second protective tube 4 cooperate with each other to form a protective sleeve. Positioning structures 3 are provided on both sides of the protective sleeve. The positioning structures 3 can be used to position the first protective tube 1 and the second protective tube 4, so that the first protective tube 1 and the second protective tube 4 remain stable after being installed on the outside of the hose body 2.

[0033] Please see Figures 2 to 4 The positioning structure 3 includes a slot 301, a connecting rod 302, a mounting hole 303, a connecting block 304, an anti-slip pad 305, a positioning plate 306, a positioning rod 307, and a positioning hole 308. The first protective tube 1 and the second protective tube 4 are fitted together. There are two positioning plates 306, one on each side of the first protective tube 1 and the other on each side, and the side walls of the two positioning plates 306 are fitted together. The slot 301 is opened on the upper surface of the positioning plate 306 connected to the first protective tube 1. Multiple positioning blocks 103 are fixedly connected at intervals on the lower surface of the first protective tube 1. Multiple positioning grooves 104 are opened at intervals on the upper surface of the second protective tube 4. The positioning blocks 103 cooperate with the positioning grooves 104 so that the first protective tube 1 and the second protective tube 4 can remain stable after they cooperate with each other, and avoid misalignment.

[0034] The first protective tube 1 and the second protective tube 4 are provided with clamps 102, which can clamp the hose body 2. The surface of the clamp 102 is provided with a locking block 105, which cooperates with the groove 106 to position the hose body 2 and prevent the hose body 2 from sliding inside the first protective tube 1 and the second protective tube 4. The hose body 2 is installed between the first protective tube 1 and the second protective tube 4.

[0035] The hose body 2 is provided with a partition layer 205, a tensile layer 204, a metal wire mesh 203, a buffer layer 202 and an outer layer 201 from the inside out. The outer layer 201 has a plurality of grooves 106 spaced apart on its outer side. The locking block 105 cooperates with the grooves 106. The partition layer 205 is made of cross-linked polyethylene, the tensile layer 204 is made of nylon, and the buffer layer 202 is made of polyurethane. Cross-linked polyethylene has good tensile strength, nylon has strong tensile strength, and polyurethane has good buffering effect.

[0036] Positioning holes 308 are formed at the four corners of the upper surface of one of the positioning plates 306. Positioning rods 307 are fixedly connected to the four corners of the lower surface of the other positioning plate 306. Positioning holes 308 and positioning rods 307 cooperate to position and install the two adjacent positioning plates 306 respectively. A mounting block is provided inside the slot 301. The lower surface of the mounting block is fixedly connected to the upper end of the connecting rod 302. The side wall of the connecting block 304 is fixedly connected to the side wall of the connecting rod 302.

[0037] The upper surface of the anti-slip pad 305 is fixedly connected to the lower surface of the connecting block 304. The mounting hole 303 is opened through the middle of the connecting block 304 and passes through the middle of the anti-slip pad 305. The bolt can pass through the middle of the mounting hole 303. By pulling downward, the first protective tube 1 can press the second protective tube 4, which can keep the first protective tube 1 and the second protective tube 4 stable. The slot 301 is opened on the upper surface of the positioning plate 306, which is fixedly connected to the side wall of the first protective tube 1.

[0038] The groove 106 extends through the outer side of the outer layer 201 to the inside, and the outer side of the hose body 2 fits against the inner wall of the clamp 102.

[0039] The external part of the positioning block 103 fits into the internal part of the positioning groove 104, and the external part of the positioning rod 307 fits into the internal part of the positioning hole 308.

[0040] The reinforcing ribs 101 inside the first protective tube 1 and the second protective tube 4 are arranged in a cross pattern. The reinforcing ribs 101 are arranged in both the horizontal and vertical directions and are fixedly connected to the side wall of the clamp 102.

[0041] The implementation principle of the novel plastic hose in this application embodiment is as follows:

[0042] First, the hose body 2 is installed inside the clamp 102 on the upper surface of the second protective tube 4, the first protective tube 1 is placed on the second protective tube 4, and the positioning block 103 cooperates with the positioning groove 104, and the positioning rod 307 cooperates with the positioning hole 308, thereby installing and positioning the first protective tube 1 and the second protective tube 4. Moreover, the locking block 105 cooperates with the groove 106 to lock the hose body 2 between the first protective tube 1 and the second protective tube 4, so that the hose body 2 will not slide in the middle of the first protective tube 1 and the second protective tube 4.

[0043] Secondly, the outer part of the mounting block is fitted with the inner part of the slot 301 by the connecting rod 302, and the connecting block 304 at the lower end of the connecting rod 302 is fitted with the ground. The anti-slip pad 305 is used to restrict the position of the connecting block 304 so that the bolt will not slip when it is installed on the connecting block 304, thereby facilitating the positioning of the hose body 2.

[0044] Finally, the cross-linked polyethylene partition layer 205 on the inner side of the hose body 2 has good chemical resistance and physical properties, as well as good water and oxygen barrier properties, so as to play a good isolation effect on the transported liquid. The nylon tensile layer 204 has strong tensile strength to prevent the entire hose from being easily torn apart, while the polyurethane buffer layer 202 is relatively soft and can play a good cushioning effect when the entire hose is subjected to impact.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
