Description

Technical Field

[0001] The utility model belongs to the field of water meter installation, in particular to a water meter installation and connection device. Background Art

[0002] A water meter is an instrument for measuring water flow, mostly the cumulative flow of water. A water meter is generally installed between two water pipes. The joints at both ends of the water meter are connected to the water inlet pipe and the water outlet pipe, and the joints are tightened with a wrench to ensure that the connection is firm and leak-proof. However, when installing existing water meters, there is a gap between the water pipes reserved at both ends. If the reserved gap is long, it is necessary to add another connecting pipe between the water meter and the water pipe, and then tighten it through threaded fit. The operation is complicated. Therefore, we have designed a water meter installation connection device with adjustable length. Utility Model Content

[0014] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0015] A water meter installation connection device, such as Figure 1 、 2As shown in Figures 3 and 4, it includes a water meter 1, and water pipes 2 are provided on both sides of the water meter 1 through threaded connection. The two sides of the water meter 1 are connected to the water pipes 2 through a connecting mechanism. The connecting mechanism includes an outer tube 3, and the inner tube 4 is airtightly slidably connected to the outer tube 3. The outer tube 3 is threadedly connected to one end of the water meter 1, and the inner tube 4 is threadedly connected to one end of the water pipe 2. The utility model has a simple structure and an ingenious design. By utilizing the inner tube 4, it can be extended and retracted in the outer tube 3, which is convenient for adjusting according to the different lengths of the gaps between the water pipes 2 at both ends of the water meter 1. It is simple to operate, more applicable, meets market demand, and is suitable for promotion. When using the utility model, first connect the two ends of the water meter 1 to the outer tube 3 through threaded connection, adjust the length of the inner tube 4 extending out of the outer tube 3 according to the distance between the water pipes 2 on both sides, and connect the inner tube 4 to the water pipe 2 through threaded connection.

[0016] Specifically, as shown in the figure, the outer circumference of the inner tube 4 in this embodiment is threaded and fitted with a sleeve 20. The outer circumference of the inner tube 4 is provided with an external thread, and the inner circumference of the sleeve 20 is provided with an internal thread. The sleeve 20 passes through the outer tube 3 and is rotatably connected to the first ring 21 via a bearing. The sleeve 20 is fixedly connected to the inner circumference of the bearing, and the outer circumference of the bearing is fixedly connected to the first ring 21. The first ring 21 is slidably fitted over the outer circumference of the inner tube 4, and the inner circumference of the inner tube 4 is fixedly fitted with a second ring 22. An annular airbag 23 is provided between the first and second rings 21, and the annular airbag 23 is fitted over the outer circumference of the inner tube 4. Rotating the sleeve 20 can drive the first ring 21 to move, and the first ring 21 approaching the second ring 22 can squeeze the annular airbag 23. The outer circumference of the annular airbag 23 is tightly fitted with the inner wall of the outer tube 3, which can increase the airtightness between the inner tube 4 and the outer tube 3.

[0017] Specifically, as shown in the figure, the outer periphery of the sleeve 20 of this embodiment is threaded, and the outer tube 3 is provided with a threaded hole 30, and the sleeve 20 is threadedly mounted in the threaded hole 30. By rotating the sleeve 20 and the inner tube 4 simultaneously, they can be driven to move together, thereby controlling the length of the inner tube 4 extending from the outer tube 3, making it suitable for water pipes 2 with different gaps on both sides of the water meter 1.

[0018] Furthermore, as shown in the figure, the outer periphery of the inner tube 4 and the outer periphery of the sleeve 20 in this embodiment are respectively fixed with an outer hexagonal nut 40. By screwing the outer hexagonal nut 40 with the help of a wrench, it is easier to rotate the sleeve 20 and the inner tube 4.

[0019] Furthermore, as shown in the figure, the water meter 1 of this embodiment has external threads at its two connection points, and internal threads at its connection point with the water pipe 2. One end of the outer pipe 3 has internal threads, and one end of the inner pipe 4 has external threads. The two sides of the water meter 1 can be connected to the water pipe 2 not only directly, but also through the outer pipe 3 and the inner pipe 4, with the external and internal threads correspondingly arranged.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
