Technical Field
[0001] The utility model relates to the technical field of corrugated pipe assembly, in particular to a double-closed corrugated pipe pressing device. Background Art
[0002] The double-wall corrugated pipe, also known as the double-closed corrugated pipe, is a new type of lightweight pipe with a ring-shaped outer wall and a smooth inner wall. The main material is HDPE (high-density polyethylene) or other plastic materials, which has good corrosion resistance and aging resistance. At the same time, the outer wall of the double-wall corrugated pipe is in a ring-shaped corrugated shape, and the inner wall is smooth and flat. This structure enhances the ring stiffness of the pipe, making its resistance to external loads significantly enhanced. Due to the light weight of the double-wall corrugated pipe, it is convenient to handle and connect, with fast construction and simple maintenance, so this kind of pipe has a wide range of applications in many fields.
[0003] At the present stage, in the automotive manufacturing industry, in order to effectively protect automotive wiring harnesses, generally the form of double-layer corrugated pipes is adopted, that is, the corrugated pipe is divided into an inner layer and an outer layer, and the outer corrugated pipe mouth is sleeved on the inner-layer corrugated pipe through a closed end, so as to increase the strength of the corrugated pipe and further improve the protection effect on the wiring harness.
[0004] Although the above form of double-layer corrugated pipes can better protect the wiring harness, there are still the following deficiencies in actual use: during assembly, the operator is very likely to misalign the wave crests of the two layers of corrugated pipes, resulting in the phenomenon of the wiring harness bulging. It is necessary to use manual pressing to complete the buckling and assembly of the two layers of corrugated pipes, with high labor intensity and unstable product quality. Summary of the Utility Model
[0005] The purpose of the utility model is to overcome the deficiencies in the prior art, such as the wave crests of the two layers of corrugated pipes being easily misaligned, high labor intensity, and unstable product quality, and to provide a double-closed corrugated pipe pressing device, which is reasonable in design, simple in structure, and convenient to operate. It can not only effectively reduce the labor intensity, improve work efficiency, but also improve product quality.
[0006] The utility model is realized by the following technical solutions: a double-closed corrugated pipe pressing device includes two pressing plates. The pressing plates are of a semi-circular structure, and the two pressing plates are hinged to each other so as to form a pressing sleeve that can be opened or closed, and the inner diameter of the pressing sleeve is adapted to the outer diameter of the corrugated pipe; a longitudinal support rod is connected to the outer side surface of one of the pressing plates. The upper end of the longitudinal support rod extends above the pressing plate, and the lower end of the longitudinal support rod is fixedly connected to the outer side surface of the pressing plate; a transverse connecting rod is connected to the upper end of the longitudinal support rod. The front end of the transverse connecting rod extends towards the outside of the pressing plate, and the rear end of the transverse connecting rod is fixedly connected to the upper end of the longitudinal support rod; a guide is rotated at the front end of the transverse connecting rod, and the guide can penetrate into the inner layer of the corrugated pipe to guide the corrugated pipe.
[0007] A further improvement of the present utility model is that the guide is arranged in parallel with the front end of the transverse link, and the side surface of the guide is rotatably connected to the front end of the transverse link.
[0008] A further improvement of the present utility model is that the guide includes two guide plates. One side of the two guide plates is integrally connected, and the other side of the two guide plates is separated, so that the guide can form a structure with one side closed and the other side open.
[0009] A further improvement of the present utility model is that the closed side of the guide faces the inner side direction of the pressing plate, and the open side of the guide faces the outer side direction of the pressing plate.
[0010] A further improvement of the present utility model is that the upper end of the guide plate is an arc structure, the lower end of the guide plate is a sharp corner structure, and the sharp corner of the guide plate keeps facing the pressing plate.
[0011] A further improvement of the present utility model is that the included angle between the two guide plates is an acute angle.
[0012] A further improvement of the present utility model is that both sides of the two guide plates where they are separated are provided with flanging folded outward.
[0013] A further improvement of the present utility model is that the transverse link is arranged obliquely upward, and the included angle between the transverse link and the longitudinal support rod is 45°.

[0022] To make the purpose, features, and advantages of the present utility model more obvious and understandable, the technical solutions in the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in this specific embodiment. Obviously, the embodiments described below are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments in this patent, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of this patent.
[0023] Now referring to the attached Figures 1-3 , in combination with specific embodiments, the description is as follows: A double-closed bellows pressing device described in the present utility model includes two aluminum pressing plates 1. The pressing plate 1 is of a semi-circular structure. The two pressing plates 1 are hinged to each other, so as to form a pressing sleeve that can be opened or closed, and the inner diameter of the pressing sleeve is adapted to the outer diameter of the bellows. During actual use, the pressing sleeve can generally adapt to bellows with an outer diameter in the range of 15 mm - 22 mm.
[0024] An aluminum longitudinal support rod 2 is connected to the outer side surface of one of the pressing plates 1. The upper end of the longitudinal support rod 2 extends above the pressing plate 1, and the lower end of the longitudinal support rod 2 is fixedly connected to the outer side surface of the pressing plate 1; the upper end of the longitudinal support rod 2 is connected to an aluminum transverse connecting rod 3. The front end of the transverse connecting rod 3 extends towards the outside of the pressing plate 1, and the rear end of the transverse connecting rod 3 is fixedly connected to the upper end of the longitudinal support rod 2.
[0025] Specifically, the transverse connecting rod 3 is inclined obliquely upwards, and the included angle between the transverse connecting rod 3 and the longitudinal support rod 2 is 45°. This design of the transverse connecting rod 3 can better support the inner-layer bellows and maximize the guarantee of being parallel to the pressing sleeve.
[0026] A plastic guide 4 is rotatably connected to the front end of the transverse link 3. The guide 4 includes two guide plates 401. One side of the two guide plates 401 is integrally connected, and the other side of the two guide plates 401 is separated from each other, so that the guide 4 can form an included angle structure with one side closed and the other side open, and the included angle between the two guide plates 401 is an acute angle; the closed side of the guide 4 faces the inner side direction of the pressing plate 1, and the open side of the guide 4 faces the outer side direction of the pressing plate 1; the guide 4 can penetrate into the interior of the inner corrugated pipe, so as to guide the corrugated pipe.
[0027] The working principle of the present utility model:
[0028] First, insert the guide 4 into the closed end of the inner corrugated pipe, open the pressing sleeve, then place the outer corrugated pipe into the interior of the pressing sleeve. After placing the outer corrugated pipe, buckle one end of the inner corrugated pipe into the inner part of the outer corrugated pipe. After the buckling is completed, close the pressing sleeve. At this time, push out the buckled end from the pressing sleeve, and the staff directly continues to push in the direction from top to bottom of the pressing sleeve. In this process, the two-layer corrugated pipes can be pressed together, that is, the assembly process is completed. During the entire pushing and pressing process, under the action of the pressing sleeve, the wave crests of the two-layer corrugated pipes can be automatically pressed into one body without causing misalignment and bulging. At the same time, the guide 4 penetrates into the closed end of the inner part of the corrugated pipe. During the pushing process, under the action of the guide 4, the inner corrugated pipe can always be kept in a parallel state, and the guide 4 is clamped at the closed end of the inner corrugated pipe, so that the inner corrugated pipe will not be bent, thus playing a guiding role.
[0029] In one embodiment, the guide 4 is arranged in parallel with the front end of the transverse link 3, and the side surface of the guide 4 is rotatably connected to the front end of the transverse link 3. This design is more reasonable to facilitate inserting the guide 4 into the inner corrugated pipe.
[0030] In one embodiment, the upper end of the guide plate 401 is a rounded corner structure, the lower end of the guide plate 401 is a pointed corner structure, and the pointed corner of the guide plate 401 faces the pressing plate 1.
[0031] In one embodiment, flanging 402 that turns outwards is provided on one side where the two guide plates 401 are separated from each other, and the upper end of the flanging 402 is a rounded corner structure. This design of the flanging 402 can further improve the guiding effect of the guide 4.
[0032] In one embodiment, both the longitudinal support rod 2 and the transverse link 3 are hexagonal rod bodies. The hexagonal rod body is firm and not easily deformed. Using this kind of rod body can further improve the overall strength of the present pressing device.
[0033] In one of the embodiments, an inner chamfer 101 with an angle of 35° is provided on the inner side of the upper end of the pressing plate 1. Through the design of the inner chamfer 101, the smoothness of the bellows during pushing can be ensured, thereby further improving the pressing effect of the pressing device.
[0034] The various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. For the same or similar parts among the various embodiments, reference can be made to each other.
