Description

Technical Field

[0001] The utility model relates to the technical field of water pipe joints, in particular to a double-telescopic universal curved-leg connector. Background Art

[0002] When connecting water pipes, quick-connect sealing heads are generally used to quickly and effectively connect two sets of plastic water pipes. The quick-connect sealing heads can greatly extend the usable length of the water pipes to meet the needs of use. However, for the situation where the upstream and downstream water pipes are not coaxial and have a partition in the middle, the traditional straight pipe quick connector cannot be used. The use of elbow quick connectors requires additional filling of foam or other fillers at the installation hole to seal the installation hole, resulting in the installation position being less beautiful and difficult to clean. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a double-telescopic universal curved-leg connector, comprising an upper tube, a lower tube, a connecting plate and a connecting tube, the bottom end of the upper tube is fixed to the top surface of the left end of the connecting plate, the top end of the lower tube is fixed to the bottom surface of the right end of the connecting plate, and a channel connecting the upper tube and the lower tube is opened in the middle of the connecting plate; the upper tube and the lower tube are both sleeved with connecting tubes, and the connecting tubes can rotate axially on the upper tube or the lower tube; the outer wall of the connecting tube is threaded, and a fastening ring is provided at the top end of the connecting tube, and a fastening screw mouth is provided from the side wall of the fastening ring to the inner wall of the fastening ring, and a fastening screw is screwed into the fastening screw mouth.

[0004] Furthermore, a plurality of sealing grooves are arranged on the outer walls of the upper tube and the lower tube, and sealing rings are embedded in the sealing grooves, and the sealing rings are interference fit with the connecting tube.

[0005] Furthermore, the outer wall of the upper tube or lower tube where the sealing groove is located is a straight tube with the same upper and lower diameters, and the diameters of the upper tube or lower tube at other positions gradually increase from the end close to the connecting plate to the end away from the connecting plate.

[0006] The beneficial effects of the present invention are as follows: the upper tube and the lower tube are connected by a connecting plate, the upper and lower water pipes with different axes are connected by a sleeve connecting tube, and the sealing ring is used for sealing to prevent the problem of water pipe leakage. The upper tube and the lower tube are connected by the connecting plate, which is more convenient during installation. At the same time, the connecting tube can rotate axially on the upper tube or the lower tube and change the degree of sleeve arrangement, thereby realizing universal steering function and telescopic function, making the installation position more regular and convenient to clean.

[0010] In order to make the purpose, technical solutions and advantages of the present application clearer, the present invention is further described in detail below in conjunction with the embodiments. In order to thoroughly understand the present invention, some specific details will be involved in the following description. In the absence of these specific details, the present invention can still be implemented, that is, those skilled in the art can more effectively introduce the essence of their work to other technicians in the field using these descriptions and statements here. In addition, it should be noted that it should be understood that the specific embodiments described herein are merely used to explain the present application and are not intended to limit the actual scope of protection. All raw materials used in the following examples are commercially available products.

[0011] Example 1

[0012] like Figure 1-Figure 2 As shown, a double-telescopic universal curved-leg connector includes an upper tube 1, a lower tube 2, a connecting plate 3 and a connecting tube. The bottom end of the upper tube 1 is fixed to the top surface of the left end of the connecting plate 3, and the top end of the lower tube 2 is fixed to the bottom surface of the right end of the connecting plate 3. A channel connecting the upper tube 1 and the lower tube 2 is opened in the middle of the connecting plate 3; the upper tube 1 and the lower tube 2 are both sleeved with connecting tubes, and the connecting tubes can be axially rotated on the upper tube 1 or the lower tube 2; the outer wall of the connecting tube is threaded, and a fastening ring 5 is provided at the top of the connecting tube. A fastening screw hole 6 is provided from the side wall of the fastening ring 5 to the inner wall of the fastening ring 5, and a fastening screw is screwed into the fastening screw hole 6.

[0013] A plurality of sealing grooves 4 are arranged on the outer walls of the upper tube 1 and the lower tube 2 , and sealing rings are embedded in the sealing grooves 4 , and the sealing rings are interference fit with the connecting tube.

[0014] The outer wall of the upper tube 1 or lower tube 2 where the sealing groove 4 is located is a straight tube with the same upper and lower diameters, and the diameters of the upper tube 1 or lower tube 2 at other positions gradually increase from the end close to the connecting plate 3 to the end away from the connecting plate 3.

[0015] During use, the connecting pipe is respectively sleeved on the upper pipe 1 and the lower pipe 2. When the connecting pipe is sleeved, the end with the fastening ring 5 is sleeved close to the connecting plate 3. After the connecting pipe is sleeved, it is rotated according to the position of the upstream pipe and the downstream pipe so that the connecting plate is placed in the desired direction. The connecting pipe is then screwed to the corresponding upstream pipe or downstream pipe through a thread. After the connecting pipe is screwed, the fastening screw is screwed into the fastening screw hole 6 so that the fastening screw abuts against the side wall of the upper pipe 1 or the lower pipe 2 to tighten the connecting pipe, thus completing the connection between the upstream pipe and the downstream pipe. When connecting, the upper and lower positions of the connecting plate 3 can be adjusted by adjusting the degree to which the connecting pipe is screwed into the pipe to be connected. The degree to which the connecting pipe is sleeved on the upper pipe 1 or the lower pipe 2 can be selected according to the situation, so that the connecting plate 3 is finally flush with the surface to be installed, achieving a seamless connection. At the same time, multiple sealing rings are provided on the outside of the upper pipe 1 and the lower pipe 2. Regardless of the degree to which the connecting pipe is sleeved, it can ensure that at least one sealing ring seals the connecting pipe with the upper pipe 1 or the lower pipe 2.

[0016] The utility model connects the upper tube 1 with the lower tube 2 through a connecting plate, and sleeves the connecting pipe to connect the water pipes with different axes above and below, and cooperates with the sealing ring to seal to prevent the problem of water pipe leakage. It is more convenient to connect the upper tube 1 and the lower tube 2 through the connecting plate 3. At the same time, the connecting pipe can rotate axially on the upper tube 1 or the lower tube 2 and change the degree of sleeves above and below, realizing universal steering function and telescopic function, making the installation position more regular and convenient to clean.

[0017] The technical solutions provided by the embodiments of the present invention are introduced in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the embodiments of the present invention. The description of the above embodiments is only applicable to help understand the principles of the embodiments of the present invention. At the same time, for those skilled in the art, according to the embodiments of the present invention, there may be changes in the specific implementation methods and application scope. In summary, the contents of this specification should not be understood as limiting the present invention.
