Description

Technical Field

[0001] This utility model relates to the field of support device structure technology, and more specifically, to a cylindrical heavy-duty support device. Background Technology

[0002] In the context of the booming development of modern mechanical engineering and manufacturing, heavy-duty support structures, as key load-bearing components, are widely used in many fields and play an indispensable role. From internal support components of large mechanical equipment to key components on industrial production lines, the demand for heavy-duty support structures continues to grow.

[0003] Traditional support structures of this type are mostly made of metal materials (such as cast steel and aluminum alloy) and formed by machining or welding. They have problems such as heavy weight, easy corrosion, high processing cost and easy scratches on the contact surface.

[0004] Therefore, it is necessary to provide a new cylindrical heavy-duty support device. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a cylindrical heavy-duty support device. The support device provided by this utility model is integrally molded from engineering plastic injection molding, and has the characteristics of high strength, high toughness, and moderate rigidity, and will not scratch other parts in contact with it.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A cylindrical heavy-duty support device is integrally injection molded from engineering plastic, including a cylindrical body. Multiple protrusions and recesses extending along the height direction of the cylindrical body are formed on the outer peripheral sidewall of the cylindrical body. The protrusions and recesses are arranged adjacent to each other. The protrusions extend radially outward along the cylindrical body, and the recesses extend radially inward along the cylindrical body. A stepped portion and a limiting portion located at the upper end of the inner sidewall of the cylindrical body are formed. The limiting portion has a wedge-shaped structure.

[0008] Furthermore, the cylindrical body forms the stepped portion on the inner sidewall corresponding to each of the recesses.

[0009] Furthermore, the limiting portion is formed on the inner sidewall of the cylinder corresponding to a portion of the protrusion.

[0010] Furthermore, the limiting part is provided in 3 to 5 parts.

[0011] Furthermore, the cylinder body has an outward flange formed at the upper end of a portion of the protrusion.

[0012] Furthermore, gaps are provided on both sides of each limiting part and on both sides of the flange at the upper end of the cylinder.

[0013] Furthermore, the bottom of the cylinder is provided with an inwardly extending inner flange.

[0014] Furthermore, an opening is provided on the inner flange at the position corresponding to each of the limiting portions.

[0015] Furthermore, the lower end face of the limiting part is provided with a chamfer on the side near the cylinder.

[0016] Furthermore, a raised strip is formed on the outer side of the protrusion.

[0017] The beneficial effects of this utility model are as follows:

[0018] The cylindrical heavy-duty support device provided by this utility model forms a wave-like interlaced structure by setting multiple protrusions and recesses on the cylindrical wall, thereby enhancing the axial load-bearing capacity of the cylindrical body. Under the same wall thickness, it effectively increases the load-bearing capacity, and under the same inner and outer diameter, the weight is much lower than that of a thick-walled straight cylindrical support cylinder. Moreover, by setting a limiting part, the problem of easy detachment of interface parts placed on the cylindrical body can be effectively solved without adding other fastening parts, and the interface parts after installation can be effectively limited axially and radially.

[0027] The structure provided by this utility model will be explained and described in detail below with reference to the accompanying drawings.

[0028] refer to Figures 1 to 3 As shown, this embodiment specifically discloses a cylindrical heavy-duty support device, which is integrally injection molded from engineering plastic. The engineering plastic can be made of materials such as polyamide, polycarbonate, or polyetheretherketone, possessing high strength and high toughness. The support device includes a cylindrical body 1. Multiple protrusions 2 and recesses 3 extending along the height direction of the cylindrical body 1 are formed on the outer peripheral sidewall of the cylindrical body 1. The protrusions 2 and recesses 3 are arranged adjacent to each other. The protrusion direction of the protrusions 2 extends radially outward along the cylindrical body 1, and the concave direction of the recesses 3 extends radially inward along the cylindrical body 1. Figure 1 As shown, multiple staggered protrusions 2 and recesses 3 form a wave-like structure. It can be understood that the protrusions 2 and recesses 3 are mainly relative to the outer wall of the cylinder 1. The wave-like structure design of the cylinder 1 enhances the axial load-bearing capacity of the cylinder 1. Under the same wall thickness, it effectively increases the load-bearing capacity. Under the same inner and outer diameter, the weight is much lower than that of the thick-walled straight cylinder support cylinder.

[0029] A step portion 5 and a limiting portion 4 located at the upper end of the inner wall of the cylinder 1 are formed. The limiting portion 4 has a wedge-shaped structure, that is, the upper end surface of the limiting portion 4 has an inclined surface, which facilitates assembly.

[0030] Combination Figure 2 As shown, the support device of this utility model is used to install the interface component 100. The interface component 100 is also cylindrical, with an outer flange 110 formed at its bottom. The interface component 100 is used to install on the cylinder 1, and then other objects such as heavy ammunition can be installed on the interface component 100, or it can also be used to support machining equipment, etc.

[0031] In this embodiment, by using the wedge-shaped limiting part 4, the problem of easy detachment of the interface component 100 can be effectively solved without adding other fastening components, and the interface component 100 can be effectively limited axially and radially after installation.

[0032] In this embodiment, the cylinder 1 forms a step portion 5 on the inner sidewall corresponding to each recess 3; the step portion 5 is mainly used to support the interface component 100, and its upper end face is in contact with the bottom of the interface component 100; the step portion 5 is formed on the inner sidewall corresponding to each recess 3, which can provide a more stable support effect for the interface component 100.

[0033] In some embodiments, a limiting part 4 is formed on the inner sidewall of the cylinder 1 corresponding to the protrusion 2, so that the limiting part 4 and the step part 5 are also staggered. There are 3 to 5 limiting parts 4. In the embodiment shown in the figure, there are 3 in total, which are evenly distributed on the inner sidewall of the upper end of the cylinder 1. In use, one side of the outer flange 110 of the interface component 100 is inserted into one limiting part 4, and the other side is raised. By pressing the interface component 100, the other two limiting parts 4 are squeezed, so that the outer flange 110 can be completely inserted into the limiting part 4, thereby fixing the interface component 100 and realizing the function of quick installation and anti-drop-off. At this time, the bottom surface of the limiting part 4 is in contact with the top surface of the outer flange 110, and the interface component 100 is supported and fixed by the limiting part 4 and the step part 5.

[0034] Continue to combine Figures 1 to 3 As shown, in some embodiments, the cylinder 1 also has an outwardly facing flange 9 formed at the upper end of a portion of the protrusion 2. In the illustrated embodiment, the flange 9 is disposed between two adjacent limiting portions 4. The flange 9 is mainly used to limit the movement of the cylinder 1 when it is fitted inside an external cylindrical component (such as a metal tube) by contacting and pressing against the outer wall of the tube. That is, in some embodiments, the support device provided by this utility model can be installed inside a metal tube to further enhance its support performance.

[0035] Furthermore, in some embodiments, a ridge 10 is formed on the outer side of some of the protrusions 2; in the illustrated embodiment, the ridge 10 is provided on the protrusion 2 corresponding to each limiting part 4; the ridge 10 has the same function as the flange 9 described above, and is also used to limit the contact and compression with the outer wall of the tube.

[0036] In some preferred embodiments, gaps 11 are provided on both sides of each limiting part 4 and on both sides of the flange 9 at the upper end of the cylinder 1. The gaps 11 facilitate the insertion and separation of the interface components 100, as well as the separation of the cylinder 1 from the outer pipe wall.

[0037] Continue to refer to Figure 1 and Figure 3 As shown, the bottom of the cylinder 1 is provided with an inwardly extending inner flange 6, which can increase the support area at the bottom and ensure support stability; furthermore, the inner flange 6 is provided with a U-shaped opening 7 at the position corresponding to each limiting part 4. By providing an opening at the bottom, the limiting part 4 on the cylinder 1 can be directly formed during the injection molding process without secondary processing.

[0038] Continue to combine Figure 4 As shown, a chamfer 8 is provided on the lower end face of the limiting part 4 near the cylinder 1; this facilitates the smooth demolding of the limiting part 4 after molding, reduces friction and resistance during demolding, and helps improve production efficiency.
