Description

Technical Field

[0001] This utility model relates to the technical field of engineering plastic pipes, and in particular to an adjustable high-strength engineering plastic pipe. Background Technology

[0002] Engineering plastic pipes are widely used in municipal engineering, highway bridges, civil engineering, and cable laying. Corrugated plastic pipes are adjustable, allowing for extension and bending. For example, in cable laying, cables are threaded through corrugated plastic pipes, which protect the cables from external environmental corrosion.

[0003] In the existing technology, due to the stretchable and bendable properties of corrugated plastic pipes, the strength of the extended folded parts is reduced. If the pipes are subjected to external impacts during installation, the extended folded parts may dent. If the impact force is too large, the extended folded parts of the corrugated plastic pipes may crack or break, thus affecting the protection of the cables. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an adjustable high-strength engineering plastic pipe in order to solve the technical problems mentioned in the background art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] An adjustable high-strength engineering plastic pipe includes a corrugated pipe, wherein an annular skeleton is connected to the recessed part on the outer side wall of the corrugated pipe, and a reinforcing component is provided between two adjacent annular skeletons.

[0007] The reinforcing component includes a plurality of grooves formed on the annular frame. A pivot is connected between two opposite inner sidewalls in each groove. A movable rod is rotatably connected to each pivot. A sliding groove is formed at the end of each movable rod. A first support rod and a second support rod are slidably connected to two corresponding movable rods through the sliding grooves. An inlay cover is connected to the end of the first support rod, and a universal ball is connected to the end of the second support rod. The universal ball is embedded in the inlay cover and rotatably connected to the inlay cover.

[0008] In a preferred embodiment, the present invention can be further configured such that: the groove at the end of the movable rod is narrowed, and a sliding piece is slidably connected in the groove, with each sliding piece connected to the corresponding first support rod and second support rod respectively.

[0009] In a preferred embodiment, the present invention can be further configured such that: each of the protruding portions on the outer periphery of the corrugated pipe is connected to an outer positioning ring, and a gap is left between the outer periphery of the outer positioning ring and the first support rod and the second support rod.

[0010] In a preferred embodiment, the present invention can be further configured such that: a plurality of internal hollow grooves are formed in the side wall of the corrugated pipe, and a limiting block is connected to each of the two end side walls of the internal hollow groove, and a limiting steel wire is connected between the corresponding two limiting blocks.

[0011] In a preferred embodiment, the present invention can be further configured such that: a fixing ring is connected to each of the two ends of the bellows, and the two fixing rings are respectively connected to the corresponding limiting block.

[0012] In a preferred embodiment, the present invention can be further configured such that: the outer peripheral side of the limiting steel wire is fitted with the inner peripheral side of the corresponding inner hollow groove, and the outer peripheral side of the limiting steel wire is fixedly connected to the inner peripheral side of the inner hollow groove.

[0013] In summary, this utility model has at least one of the following beneficial technical effects:

[0014] 1. This adjustable high-strength engineering plastic pipe, when in use, utilizes reinforcing components to protect the outer periphery of the corrugated pipe, forming a mesh-like protective structure. This structure can adaptively adjust to the stretching and bending of the corrugated pipe, improving the outer strength of the corrugated pipe and preventing excessive deformation and breakage after impact. Damage to the corrugated pipe would compromise the protection of the wiring, thus increasing the strength of the corrugated pipe and enhancing its overall strength.

[0015] 2. The adjustable high-strength engineering plastic pipe has a groove at the end of the movable rod that is designed to be narrowed. When the corrugated pipe is stretched, it will drive the corresponding annular skeleton to move. When the annular skeleton moves, it will pull the corresponding movable rod, the first support rod and the second support rod. The sliding piece is used to limit the movement within the groove to prevent the first support rod and the second support rod from being pulled out of the groove when the corrugated pipe is stretched.

[0016] 3. In this adjustable high-strength engineering plastic pipe, the outer positioning ring is used to protect the outer convex position of the corrugated pipe. When it collides with the position of the first support rod and the second support rod, it prevents the ends of the first support rod and the second support rod from contacting the outer convex position of the corrugated pipe, so as to avoid the outer circumference of the corrugated pipe being pressed and deformed.

[0017] 4. This adjustable high-strength engineering plastic pipe has an inner groove with the same curvature as the corrugated pipe. Limiting blocks are connected to the two end side walls inside the inner groove, and a limiting steel wire is connected between the two limiting blocks. The length of the limiting steel wire is the same as the length of the corrugated pipe. Therefore, when the corrugated pipe is stretched, the limiting steel wire will be stretched synchronously. After the limiting steel wire is straightened, it will limit the stretching of the corrugated pipe and prevent the corrugated pipe itself from being overstretched and damaged.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Example:

[0027] Reference Figures 1-3The present invention discloses an adjustable high-strength engineering plastic pipe, including a corrugated pipe 1, wherein an annular skeleton 2 is connected to the concave part on the outer side wall of the corrugated pipe 1, and a reinforcing component 3 is provided between two adjacent annular skeletons 2.

[0028] The reinforcing component 3 includes a plurality of grooves 4 formed on the annular frame 2. A rotating shaft 5 is connected between two opposing inner sidewalls in each groove 4. A movable rod 6 is rotatably connected to each rotating shaft 5. A sliding groove 7 is formed at the end of each movable rod 6. A first support rod 8 and a second support rod 9 are slidably connected to two corresponding movable rods 6 through the sliding groove 7, respectively. An inlay cover 10 is connected to the end of the first support rod 8, and a universal ball 11 is connected to the end of the second support rod 9. The universal ball 11 is embedded in the inlay cover 10 and rotatably connected to the inlay cover 10.

[0029] In this embodiment, reference Figure 1 The corrugated pipe 1 is used to protect the wiring during wiring. An annular frame 2 is connected to the concave portion on the outer periphery of the corrugated pipe 1, further protecting it. A groove 4 is formed in the annular frame 2. Figure 2 The rotating shaft 5 is rotatably connected within the groove 4, and a movable rod 6 is connected to the rotating shaft 5. (See reference) Figure 3 The groove 7 is provided at the end of each movable rod 6, as shown in the reference. Figure 2 The movable rod 6 is slidably connected to the first support rod 8 and the second support rod 9 in the corresponding sliding groove 7. The end of the first support rod 8 is connected to the inlay cover 10, and the end of the second support rod 9 is connected to the universal ball 11, and the universal ball 11 is rotatably connected to the inlay cover 10.

[0030] refer to Figure 2 The movable rods 6, along with the first support rods 8 and the second support rods 9, form a mesh-like protection around the bellows 1. When the bellows 1 is impacted, because the reinforcing component 3 is located outside the bellows 1, the bellows 1 will collide with the inlaid cover 10 on the reinforcing component 3 or with the first and second support rods 8 and 9. At this time, the first and second support rods 8 and 9 will rotate via their corresponding movable rods 6. As the movable rods 6 rotate, the distance between the ends of the two corresponding movable rods 6 shortens, causing the first and second support rods 8 and 9 to move into their corresponding grooves 7. After one end of the first and second support rods 8 and 9 in the corresponding grooves 7 abuts against the inner wall of the groove 7, [reference needed]. Figure 1The ring frame 2 will bear the impact force, thereby preventing the bellows 1 from being damaged due to excessive deformation after being impacted, which would affect the use of the bellows 1.

[0031] In addition, the rotatable connection between the universal ball 11 and the inlay cover 10 allows for multi-angle adjustment between the first support rod 8 and the second support rod 9 when the bellows 1 is bent, thus avoiding the impact on the bending adjustment of the bellows 1 itself after the reinforcing component 3 is set outside the bellows 1 to form protection.

[0032] In a further preferred embodiment of this utility model, such as Figure 3 As shown, the slide groove 7 located at the end of the movable rod 6 is designed to be narrowed. A slide piece 12 is slidably connected in the slide groove 7, and each slide piece 12 is connected to the corresponding first support rod 8 and second support rod 9.

[0033] In this embodiment, reference Figure 3 The groove 7 in the middle, the groove 7 opened at the end of the movable rod 6 is set to be constricted. When the bellows 1 is stretched, it will drive the corresponding annular frame 2 to move. When the annular frame 2 moves, it will pull the corresponding movable rod 6, the first support rod 8 and the second support rod 9. The sliding piece 12 is set to limit it in the groove 7, so as to prevent the first support rod 8 and the second support rod 9 from being pulled out of the corresponding groove 7 when the bellows 1 is stretched.

[0034] In a further preferred embodiment of this utility model, such as Figure 1 As shown, each of the protruding parts on the outer periphery of the corrugated pipe 1 is connected to an outer positioning ring 13, and there is a gap between the outer periphery of the outer positioning ring 13 and the first support rod 8 and the second support rod 9.

[0035] In this embodiment, reference Figure 1 The outer positioning ring 13 is used to protect the outer peripheral convex position of the bellows 1. When it collides with the position of the first support rod 8 and the second support rod 9, it prevents the ends of the first support rod and the second support rod 9 from contacting the outer peripheral convex position of the bellows 1, so as to prevent the outer peripheral side of the bellows 1 from being pressed and deformed.

[0036] In a further preferred embodiment of this utility model, such as Figure 4 As shown, a number of internal hollow grooves 14 are provided in the side wall of the corrugated pipe 1. Each of the two end side walls of the internal hollow groove 14 is connected to a limiting block 15, and a limiting steel wire 16 is connected between the corresponding two limiting blocks 15.

[0037] In this embodiment, reference Figure 4The inner hollow groove 14 has the same curvature as the bellows 1. Limiting blocks 15 are connected to the two end sidewalls of the inner hollow groove 14, and limiting steel wire 16 is connected between the two limiting blocks 15. The length of the limiting steel wire 16 is the same as the length of the bellows 1. Therefore, when the bellows 1 is stretched, the limiting steel wire 16 will be stretched synchronously. After the limiting steel wire 16 is straightened, it will limit the stretching of the bellows 1 and prevent the bellows 1 from being overstretched and damaged.

[0038] In a further preferred embodiment of this utility model, such as Figure 4 As shown, a fixing ring 17 is connected to each of the two ends of the bellows 1, and the two fixing rings 17 are respectively connected to the corresponding limiting blocks 15.

[0039] In this embodiment, reference Figure 4 The fixing ring 17 is used to fix several corresponding limiting blocks 15, and at the same time strengthens the end of the corrugated pipe 1 to prevent the end of the corrugated pipe 1 from deforming due to excessive pulling after the limiting wire 16 is pulled, which would affect the subsequent use of the corrugated pipe 1.

[0040] In a further preferred embodiment of this utility model, such as Figure 5 As shown, the outer peripheral side of the limiting steel wire 16 is fitted with the inner peripheral side of the corresponding inner hollow groove 14, and the outer peripheral side of the limiting steel wire 16 is fixedly connected to the inner peripheral side of the inner hollow groove 14.

[0041] In this embodiment, reference Figure 5 The limiting steel wire 16 is attached to the inner circumference of the inner cavity 14, so that the limiting steel wire 16 can change with the curvature change when the corrugated pipe 1 is stretched. It can be synchronized with the bending curvature of the corrugated pipe 1 when the corrugated pipe 1 is bent or stretched, thereby protecting the pipe wall of the corrugated pipe 1 and improving the strength of the corrugated pipe 1.

[0042] The implementation principle of the above embodiment is as follows: the reinforcing component 3 is used to protect the outer periphery of the bellows 1, so that the reinforcing component 3 forms a mesh protective structure and can adaptively adjust with the stretching and bending of the bellows 1, thereby improving the outer strength of the bellows 1. The wall of the bellows 1 is further reinforced by the limiting steel wire 16 to avoid the bellows 1 being overstretched and thus breaking and damaging it, thereby improving the strength of the bellows 1.

[0043] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
