Technical Field

[0001] The present application relates to the technical field of double-wall corrugated pipe auxiliary tools, and specifically to a new type of tool that can easily connect double-wall corrugated pipes. Background Art

[0002] Double-wall corrugated pipe is a pipe product used in drainage systems, usually composed of two layers of pipe walls made of different materials. The inner pipe wall is usually made of plastic materials such as polyethylene (PE) or polypropylene (PP), which has good corrosion resistance and chemical resistance; the outer pipe wall is usually made of materials such as high-density polyethylene (HDPE) or polyvinyl chloride (PVC), which has high pressure resistance and wear resistance.

[0003] At present, more and more double-wall corrugated pipes are used in actual production applications. The quick connection of corrugated pipes can effectively increase the length and facilitate construction. However, in the actual construction process, due to the activity restrictions of the corrugated pipes, the simple manual connection is not firm, and the excavator connection requires manual cooperation, which makes the connection speed too slow and unsafe. At the same time, there are shortcomings such as insufficient connection and easy damage, which increases the cost of on-site construction and affects the construction period. In response to the above-mentioned existing technical problems, we propose a new tool that can easily connect double-wall corrugated pipes. Its structure is simple and durable, and it effectively improves the efficiency of on-site connection. Utility Model Content

DETAILED DESCRIPTION

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

[0024] See also Figure 1-4 In this embodiment, a new type of tool that can easily connect a double-wall corrugated pipe includes a cross bar 1 and a first annular portion 2 and a second annular portion 3 located outside the cross bar 1, wherein the first annular portion 2 is in a semicircular arc shape corresponding to the outer wall of the corrugated pipe, and the cross bar 1 has two ends that are welded to each other;

[0025] At the same time, a spring structure is also provided on the outside of the cross bar 1 for flexibly connecting the second slow-moving portion 3, so that in actual application, the relative distance between the first annular portion 2 and the second annular portion 3 can be adjusted to facilitate docking and guiding of the two corrugated pipes.

[0026] In this embodiment, the spring structure includes a movable tube 4 slidably mounted on the outside of the cross bar 1, a connecting ring 7 is fixedly mounted on the outside of one end of the movable tube 4 away from the first annular portion 2, a cylindrical groove 6 is opened on the outside of the cross bar 1, and a return spring 8 located inside the movable tube 4 is installed on the outside of the cross bar 1.

[0027] Specifically, due to the groove 6 on the outside of the cross bar 1, the diameter of a portion of the cross bar 1 located inside the movable tube 4 is smaller than the inner diameter of the movable tube 4, so as to provide a space for accommodating the return spring 8;

[0028] Furthermore, one end of the return spring 8 abuts against the inner wall of the groove 6, and the other end is fixedly connected to the connecting ring 7. When the movable tube 4 slides relative to the cross bar 1, the return spring 8 is squeezed relative to the inner wall of the groove 6 by the connecting ring 7. Under the reverse push of the return spring 8, the movable tube 4 can be reset.

[0029] In addition, the inner wall of the connecting ring 7 is also slidably connected to the cross bar 1 provided with the groove 6, so that the sliding stability of the movable tube 4 relative to the cross bar 1 is enhanced.

[0030] It should be noted that, in order to facilitate the user to pull the second annular portion 3 close to the first annular portion 2, a hand-pushing steel pipe 5 is detachably fixed to the upper end of the movable tube 4. The hand-pushing steel pipe 5 is in a rectangular frame shape to facilitate gripping and applying force on both sides.

[0031] In order to further facilitate the disassembly and portability of the longer hand-pushed steel pipe 5, in this embodiment, the surface of the movable tube 4 is welded with bolts 16 for connection, and the lower end of the hand-pushed steel pipe 5 is rotatably mounted with a threaded tube 17 adapted to the bolts 16 through a bearing.

[0032] During the implementation process, the hand-pushed steel pipe 5 can be assembled on the movable pipe 4 to complete the connection only by rotating the threaded pipe 17 relative to the bolt 16 on the movable pipe 4 .

[0033] It is additionally noted that, in order to facilitate the use of tools to pull the threaded tube 17 to rotate, a nut may be welded on the outside of the threaded tube 17 to facilitate the use of a wrench to pull it.

[0034] In this embodiment, the connection method of the hand-pushed steel pipe 5 relative to the movable pipe 4 is not limited to the above-mentioned threaded connection method, and a welding connection method can also be directly used to improve the stability of the overall structure.

[0035] In this embodiment, a limiting structure for limiting the movable tube 4 is also provided on the cross bar 1. A tooth-shaped groove 9 is provided on the lower bottom surface of the cross bar 1. The limiting structure includes a limiting frame 11 movably mounted on the inner wall of the movable tube 4, and a bevel tooth block 12 corresponding to the tooth-shaped groove 9 is fixedly mounted on the limiting frame 11.

[0036] Preferably, the bevel gear block 12 and the toothed groove 9 are both in the shape of a right triangle, so that the bevel gear block 12 is limited in one direction compared to the toothed groove 9 .

[0037] It should be noted that a guide groove 10 for the limit frame 11 to slide is also provided on the inner wall of the movable tube 4. The lower end of the limit frame 11 slides relative to the guide groove 10, so that the limit frame 11 can move into the guide groove 10 under extrusion, so that the movable tube 4 can slide relative to the cross bar 1.

[0038] The lower end of the limit frame 11 in this embodiment is also equipped with a compression spring 15 that abuts against the guide groove 10. The compression spring 15 can push the limit frame 11 to slide and reset relative to the guide groove 10. A connecting seat 14 is fixedly installed on the lower end of the limit frame 11, and one end of the compression spring 15 is restricted and fixed in the connecting seat 14.

[0039] In this embodiment, a guide rod 13 is fixedly installed on the lower end of the limit frame 11. The guide rod 13 extends through and extends to the outside of the movable tube 4. On the one hand, it is used to guide the movement of the limit frame 11. On the other hand, the guide rod 13 extending to the outside of the movable tube 4 can be pulled down to facilitate the resetting of the movable tube 4.

[0040] The working principle of the above embodiment is:

[0041] By bringing the two bellows to be connected together, the first annular portion 2 and the second annular portion 3 are respectively embedded into the outer wall grooves of the two bellows for connection. At this time, the hand-pushing steel pipe 5 connected to the second annular portion 3 is pulled, and the hand-pushing steel pipe 5 drives the movable tube 4 to slide relative to the cross bar 1. At this time, the first annular portion 2 and the second annular portion 3 are brought close to each other, so that the two bellows are connected together. During the sliding of the movable tube 4, the beveled tooth block 12 on the inner wall of the movable tube 4 and the toothed groove 9 under the cross bar 1 are staggered and movable with respect to each other, and the inclined surface of the beveled tooth block 12 contacts the inclined surface of the toothed groove 9, thereby squeezing the limit frame 11 to move and compress relative to the guide groove 10. After sliding the movable tube 4, it is limited by the right-angled edges of the toothed groove 9 and the beveled tooth block 12 on the limit frame 11, so that the retraction of the movable tube 4 is limited, which is convenient for pre-positioning the docked bellows.
