Description

Technical Field

[0001] This application relates to the field of pipe structure technology, and in particular to a quick-release threaded pipe. Background Technology

[0002] Currently, pipes with threaded connections have good stability and leak-proof performance. However, whether it is a threaded fit between pipes or a fit between pipes through threaded connectors, a wrench is required for disassembly and assembly, and disassembly and assembly cannot be completed quickly. Summary of the Invention

[0003] The purpose of this application is to provide a threaded pipe that can be quickly and easily disassembled without the use of tools.

[0004] To achieve the above objectives, this application provides a quick-release threaded pipe: including a splicing pipe and push-pull handles. The main body of the splicing pipe is a main pipe body, the middle of which has an outwardly protruding conical ring. The end of the main pipe body has a connecting end, and the outer side of the connecting end is provided with an external thread. There are two push-pull handles, which are fixedly connected by a connector. The outwardly protruding conical ring is located between the two push-pull handles. The push-pull handles can apply additional disassembly and assembly force to the splicing pipe.

[0005] As a preferred embodiment, the convex conical ring has a pair of symmetrical frustum surfaces, the axes of the two frustum surfaces are collinear with the axis of the main body, and the convex conical surface is the force-bearing surface that directly contacts the push-pull handle.

[0006] As a preferred embodiment, the push-pull handle includes a force-applying disc, the inner wall of which has a concave conical surface, which is also a frustum of a cylinder, suitable for engaging with the convex conical ring to form a sliding pair, allowing relative sliding while applying force, thereby synchronizing with the rotational and translational motion of the helical structure.

[0007] As a preferred embodiment, the force-applying disc has a connecting hole on the portion outside the concave conical surface. The connecting component includes a bolt and a nut. The bolt passes through the connecting holes of both force-applying discs and engages with the nut. It is fixed by tightening, and the push-pull handle does not need to be disassembled frequently.

[0008] As a preferred embodiment, the number and position of the connecting holes on the two force-applying plates are the same, and the connecting holes are equidistantly arranged around the axis of the force-applying plates to ensure the stability of the connection between the two push-pull handles. At the same time, the center of the connector and the push-pull handle falls on the center line of the force-applying plate, which can effectively reduce the deflection of the push-pull handle outside the splicing pipe.

[0009] As a preferred embodiment, the axis of the connecting hole is parallel to the axis of the force-applying plate, which facilitates the disassembly and assembly of bolts and nuts.

[0010] As a preferred embodiment, each of the force-applying discs has an extended ear plate on its outer side, and each of the extended ear plates has a through hole for fingers to pass through, and also for thin rods or hooks to pass through, so as to achieve suspension.

[0011] As a preferred embodiment, each end of the main tube is connected to a connecting end via a shrink ring. The axes of the two connecting ends are collinear with the axis of the main tube, and the connecting ends can rotate synchronously with the main tube, thereby ensuring smooth rotation during assembly and disassembly.

[0012] Compared with the prior art, the beneficial effects of this application are as follows:

[0013] (1) By designing a push-pull handle structure with rotation constraint in the middle of the splicing pipe with threaded structure at both ends, a component force along the tangential direction of the helix is ​​provided when the threaded pipe is disassembled and assembled, so that the operation can be carried out without the use of a wrench, simplifying the disassembly and assembly operation and improving the disassembly and assembly efficiency.

[0014] (2) By setting an externally protruding conical ring structure in the middle of the main body and designing the push-pull handle as two parts fixed by a detachable connector, the fit between the push-pull handle and the splicing pipe is guaranteed, as well as the driving stability of the push-pull handle on the splicing pipe. This design structure is reasonable and easy to assemble. Attached Figure Description

[0024] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0026] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0027] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0028] like Figure 1-8 The quick-release threaded pipe shown includes a splicing pipe 1 and a push-pull handle 2 that can be fitted together. The splicing pipe 1 is a rotating body, and the push-pull handle 2 is flat. The axis of the splicing pipe 1 is perpendicular to the plane where the push-pull handle 2 is located. The main body of the splicing pipe 1 is a cylindrical main pipe body 101. The middle part of the main pipe body 101 has an outwardly expanding convex conical ring 102 that expands outward from the compression. The diameter of the outwardly expanding conical ring 102 gradually increases from both ends to the middle, which gives the outwardly expanding conical ring 102 a pair of symmetrical frustum surfaces. The axes of the two frustum surfaces are collinear with the axis of the main pipe body 101, thereby maintaining the rotational structure of the entire splicing pipe 1.

[0029] There are two push-pull handles 2, which need to be fixedly connected by connectors 3. In fact, the outer convex conical ring 102 is located between the two push-pull handles 2 and is limited by the two push-pull handles 2. The push-pull handle 2 includes a circular force-applying plate 201. The inner wall of the force-applying plate 201 has a concave conical surface 202, which is also a frustum of a cone. It fits perfectly with the outer convex conical ring 102 to form a sliding pair. In order to improve the smoothness of sliding, lubricating oil is usually applied to the contact surface between the push-pull handle 2 and the outer convex conical ring 102. The outer side of each force-applying plate 201 has an extension ear plate 203. The extension ear plate 203 is parallel to the plane where the push-pull handle 2 is located. Each extension ear plate 203 has a through hole 204 to facilitate the finger to pass through and lift the push-pull handle 2. There are usually two extension ear plates 203 on each push-pull handle 2. The two extension ear plates 203 are symmetrical about the axis of the force-applying plate 201.

[0030] The force-applying plate 201 has a connecting hole 205 through the upper and lower end faces on the part outside the concave conical surface 202. The connector 3 includes a bolt 301 and a nut 302 that can be matched with each other. After the bolt 301 passes through the connecting hole 205 of the two force-applying plates 201, it is tightened with the nut 302 to fix the two push-pull handles 2. The number and position of the connecting holes 205 on the two force-applying plates 201 are the same, so the connecting holes 205 on the two force-applying plates 201 can be fully aligned. The connecting holes 205 are usually equidistant from the axis of the force-applying plate 201. The axis of the connecting holes 205 is parallel to the axis of the force-applying plate 201, which facilitates the installation and matching of the bolt 301 and the nut 302.

[0031] The main body 101 has a connecting end 104 at its end, which is the main part for splicing. The outer surface of the connecting end 104 is provided with an external thread 105 for threaded engagement with other components, taking into account both stability and sealing. The two ends of the main body 101 are respectively connected to a connecting end 104 through a shrink ring 103. The axes of the two connecting ends 104 are collinear with the axis of the main body 101, so that when the main body 101 rotates, the threaded structure will also engage or disengage.

[0032] Working principle: First, install the threaded pipe. During installation, align the concave conical surfaces 202 of the two push-pull handles 2 with each other and slide them over the main pipe body 101 from both ends of the splicing pipe 1 until the concave conical surfaces 202 of the two force-applying discs 201 contact the two ends of the convex conical rings 102. The extension ear plates 203 can be aligned or not. As long as the connecting holes 205 of the two force-applying discs 201 are aligned, the two splicing pipes 1 can be fixedly connected using bolts 301 and nuts 302.

[0033] When the threaded pipe needs to be installed, first screw the connecting end 104 with the external thread 105 of the splicing pipe 1 into the mounting hole with the internal thread for a short distance. Then, apply pressure to the push-pull handle 2 in the direction close to the mounting hole. The tangential component force generated along the spiral line can speed up the screwing speed and can be screwed relatively tightly without the use of a wrench. When the threaded pipe needs to be disassembled, apply a pulling force away from the mounting hole to the push-pull handle 2. This generates a tangential component force in the opposite direction along the spiral line, which can quickly loosen the pipe without the use of a wrench and allow the threaded pipe to disengage from the mounting hole.

[0034] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
