Description

Technical Field

[0001] The utility model relates to the technical field of water pipe fittings, in particular to a split-type adjustable double-connector. Background Art

[0002] There are generally two structural forms of PPR duplex products on the market. One is an integrated structure (such as described in the patent CN201320016002.0, a PPR duplex mixing elbow). This type of product is relatively cheap, but because it is an integrated structure, its left and right ends cannot be replaced. A PPR duplex can only be connected to the matching connectors (such as double faucets, etc. For different connectors, different PPR duplex products must be developed, and many types of PPR duplex molds must be developed (because each PPR duplex mold can only be a special mold). The second type is a split type, including a double connecting rod and a detachable mounting on the The connecting pipes at both ends of the double-link (as shown in https: / / detail.1688.com / offer / 651118999928.html?spm=a261b.12309193.0.0.6e70400aXVYc0p) offer greater flexibility than the one-piece design. However, unless the two ends of the double-link are connected to the same connecting pipe, it is difficult to ensure that the metal threaded ends of the two connecting pipes are aligned, making it difficult to ensure that the two water outlets are at the same level. Therefore, improvements are necessary. Utility Model Content

DETAILED DESCRIPTION

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0022] like Figures 1 to 3 As shown, a split-type adjustable double-link connector includes a first double-linked link 1 and a second double-linked link 2. The first double-linked link 1 includes a plurality of first tooth-shaped teeth 11 provided at one end thereof, and the plurality of first tooth-shaped teeth 11 are arranged in a straight line at intervals. The first double-linked link 1 also includes a first connecting rod 12 and a first plug-in ring portion 13 connected to each other, and the plurality of first tooth-shaped teeth 11 are provided at the other end of the first connecting rod 12.

[0023] The first plug-in ring portion 13 is a cylindrical structure with two open ends and a notch 132 on the side. The first plug-in ring portion 13 includes an outwardly protruding convex ring portion 131. The convex ring portion 131 is close to a notched end of the first plug-in ring portion 13, which can make the first plug-in ring portion 13 have a certain degree of elasticity, facilitating the smooth insertion of the connecting pipe. The inner wall of the first plug-in ring portion 13, except for the inner wall of the convex ring portion 131, is polygonal with a notch, that is, its inner wall is composed of multiple rectangular wall surfaces 133 spliced ​​together, which can enable the connecting pipe to be inserted more tightly into the first plug-in ring portion 13. The first connecting rod 12 includes a pair of first connecting plates 121 spaced apart, and the pair of first connecting plates 121 are connected by a first reinforcing rib 122.

[0024] like Figures 2 and 3 As shown, one end of a pair of first connecting plates 121 is connected to the first plug-in ring portion 13. In fact, the setting direction of the pair of first connecting plates 121 is perpendicular to the opening direction of the first plug-in ring portion 13; the first double-linked rod 1 also includes a connecting plate 14 vertically connected to the pair of first connecting plates 121, and the surface of the connecting plate 14 is raised to form a first tooth-shaped tooth 11.

[0025] like Figures 4 and 5As shown, the second double-linked link 2 includes a plurality of second tooth-shaped teeth 21 provided at one end thereof, and the plurality of second tooth-shaped teeth 21 are arranged in a straight line at intervals. The second double-linked link 2 also includes a second connecting rod 22 and a second plug-in ring portion 23 that are interconnected. The plurality of second tooth-shaped teeth 21 are provided at the other end of the second connecting rod 22. The second plug-in ring portion 23 is a cylindrical structure with both ends open and a B-notch 231 on the side. This allows the second plug-in ring portion 23 to have a certain degree of elasticity, facilitating the smooth insertion of the connecting pipe. The inner wall of the second plug-in ring portion 23 is raised to form at least one stopper 232, which can limit the inserted connecting pipe to prevent the connecting pipe from being inserted too far.

[0026] The second connecting rod 22 includes a pair of spaced-apart second connecting plates 221 connected by second reinforcing ribs 222, which enhance the overall strength of the second double-linked connecting rod 2. One end of the second connecting plates 221 is connected to the second plug-in ring 23. In practice, the second connecting plates 221 are arranged perpendicular to the opening of the second plug-in ring 23. The second double-linked connecting rod 2 also includes side plates 24 perpendicularly connected to the ends of the second connecting plates 221. The surface of the side plates 24 is raised to form second tooth-shaped teeth 21.

[0027] like Figure 1 、 Figure 4 、 Figure 5 As shown, the first tooth profile teeth 11 and the second tooth profile teeth 21 are both isosceles trapezoidal columns, the short bottom surface of the first tooth profile teeth 11 is located on the inner side, and the short bottom surface of the second tooth profile teeth 21 is located on the inner side, and waist trapezoidal columnar slots are formed between two adjacent first tooth profile teeth 11 and between two adjacent second tooth profile teeth 21 respectively. The number of the first tooth profile teeth 11 is greater than the number of the second tooth profile teeth 21, and the number of the first tooth profile teeth 11 is at least one more than the second tooth profile teeth 21. The first double-linked link 1 and the second double-linked link 2 are spliced ​​into one by the cooperation and engagement of the first tooth profile teeth 11 and the second tooth profile teeth 21.

[0028] The first plug-in ring portion 13 and the second plug-in ring portion 23 have the same tube length. The first tooth-shaped teeth 11 and the second tooth-shaped teeth 21 are provided to realize the detachable connection between the first double link 1 and the second double link 2. At the same time, the plurality of second tooth-shaped teeth 21 can be engaged with the different positions of the plurality of first tooth-shaped teeth 11. The open end surface of the first plug-in ring portion 13 and the open end surface of the second plug-in ring portion 23 are in the same plane (such as Figure 1 as shown) or staggered arrangement (as shown) Figure 6 As shown), when the first plug-in ring portion 13 and the second plug-in ring portion 23 are assembled with different types of connecting pipe fittings, the metal threaded openings of the two pipe fittings can also be at the same horizontal plane or approximately the same horizontal plane, thereby achieving more convenient construction and less grooving.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
