Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of pipes, and in particular relates to a pipe connection structure. Background Art
[0002] With the booming development of Internet commerce, cross-border e-commerce has become a trend-setting business model. Cross-border e-commerce sellers are based in their own factories and serve global consumers. All goods must be delivered to buyers through logistics and express delivery, so extremely high requirements are placed on the weight and volume of product packaging. In order to control logistics costs, large items sold by e-commerce companies often need to adopt a disassembly structure, and steel pipe accessories have become one of the important research objects. The purpose is to split longer accessories into smaller parts, thereby reducing the packaging size. For pipes that require a certain structural strength, the more common splitting methods are welding the tube tongue and shrinking the tube tongue, such as Figure 1 As shown in the figure, these connection methods require the construction of a tube tongue at the pipe joint, and then the connection is made from the side of the pipe with bolts. Due to the pipe specifications, processing errors and the process characteristics of the shrink pipe, these methods are bound to leave a large gap at the joint. The two butt-jointed pipes cannot be on the same axis under the action of the bolt preload, and the connected pipes will have a certain degree of misalignment. In addition, the arc left by the shrink pipe will allow users to contact the sharp edge of another pipe, which will create a risk of scratches. Utility Model Content

[0020] In the description of the present invention, it should be understood that the directions or positional relationships indicated by the terms "center", "upper", "lower", "front", "back", "left", "right", etc. are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.
[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0022] As attached Figures 2 to 7 As shown, the utility model provides a pipe connection structure, including a first pipe section 1, a second pipe section 2 and a connecting screw 3, one end of the first pipe section 1 is provided with a first connecting block 4, one end of the second pipe section 2 is provided with a second connecting block 5, the first connecting block 4 and the second connecting block 5 are connected by the connecting screw 3, and the central axes of the first pipe section 1, the second pipe section 2 and the connecting screw 3 are on the same straight line; with the above structure, the long pipe can be divided into several sections before transportation, and the length of the package can be reduced when packing, which has the advantage of being easy to pack and transport by express delivery. When the user receives the package and needs to assemble it, it only needs to thread each two pipes through the connecting screw 3.
[0023] If there are only two pipes, a connecting block can be set at one end of one pipe, and a connecting block can be set at the other end of the other pipe. A threaded hole is set in the center of the connecting block. It should be noted that in order to ensure that multiple pipes are connected without misalignment, the threaded hole should be on the same straight line as the center axis of the pipe as much as possible.
[0024] If there are three or more pipes, only one connecting block can be set at the two ends of the pipes, and the other pipes in the middle are respectively provided with a connecting block at both ends. The structure of all connecting blocks is the same. A threaded hole that matches the thread of the connecting screw 3 is set in the middle of the connecting block. The connecting block can be welded to the pipe or bonded to the pipe by an adhesive.
[0025] like Figure 4As shown, the connecting screw 3 may be a structure with threaded structures at both ends and a non-threaded structure in the middle portion. Such a configuration can prevent the connecting screw 3 from being completely screwed onto a connecting block during installation.
[0026] Preferably, the first connecting block 4 is inserted into the first section of the pipe 1 for a certain length and then fixedly connected; the second connecting block 5 is inserted into the second section of the pipe 2 for a certain length and then fixedly connected; this allows the two adjacent pipes to be seamlessly connected as much as possible.
[0027] Preferably, the pipe is cylindrical or square cylindrical, and an open washer 6 is sleeved on the connecting screw. The minimum compressed thickness of the open washer 6 is slightly smaller than the sum of the lengths of the first connecting block 4 extending into the first section of the pipe 1 and the second connecting block 5 extending into the second section of the pipe 2. The open washer 6 is also called a spring washer and has a certain compressibility. The provision of a spring washer can increase the preload force of the connection between the pipes, and also facilitates the docking of the square cylindrical pipes and the alignment of the surfaces between the two square cylindrical pipes.
[0028] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and utility model concept of the utility model, and all these changes or substitutions should fall within the protection scope of the claims attached to the utility model.
