Description

Technical Field

[0001] The utility model belongs to the field of pipelines, and in particular relates to an angle-adjustable joint for installing a water pipe network pipeline. Background Art

[0002] The joints commonly used in water pipe network pipes include elbows, tees, crosses, etc. These joints can be used to adjust the angle of the pipe.

[0003] A Chinese patent with authorization announcement number CN217683784U discloses an angle-adjustable pipe joint, including a main body, a three-way mechanism is movably connected to the outer surface of the main body, and connecting joints are movably connected to both ends of the main body. The main body includes a main through pipe, a connecting groove is provided on the outer surface of the main through pipe, a water hole is provided inside the connecting groove, and sealing ports are provided at both ends of the main through pipe.

[0004] The above technical solution has the following defects:

[0005] Although the movable connecting pipe can be rotated inside the main pipe to adjust the angle, the internal space is relatively compact when the pipeline is laid, and the above-mentioned structure is in an "eight" shape when bent and spliced, thereby increasing the spacing between each pipeline and requiring a larger space; at the same time, for pipelines at different intervals, multiple structures need to be spliced ​​to achieve the extension function, which also makes the installation operation cumbersome. Utility Model Content

[0006] In view of the above defects, the utility model provides an angle-adjustable joint for installing a water pipe network, comprising a fixed flange and a connecting mechanism, wherein the connecting mechanism comprises a connecting pipe fixedly connected to the output end of the fixed flange, a spherical sleeve is fixed to the top of the connecting pipe, a universal spherical tube is sleeved inside the spherical sleeve, a conveying channel is provided inside the universal spherical tube, the conveying channel is connected to the connecting pipe through an inner through hole provided at the center of the outer surface of the spherical sleeve, a threaded layer is provided on the outer surface of the universal spherical tube away from the end of the spherical sleeve, a threaded tube is provided on the threaded sleeve at the threaded layer, and an extension tube is fixedly connected to the end of the threaded tube away from the connecting pipe;

[0007] The outside of the spherical sleeve is also sleeved with a matching limiting tube, a bearing is fixed to the bottom of the inner ring of the limiting tube, the inner ring of the bearing is fixed to the outer surface of the output end of the fixed flange, and the outer edge of the limiting tube is provided with a bending groove matching the universal ball tube.

[0008] Furthermore, the universal ball tube is formed by integrating a ball pin and a straight tube, and the conveying channel is opened at the vertical center axis of the ball pin and the straight tube.

[0009] The above technical solution ensures stability in the subsequent water supply process.

[0010] Furthermore, the conveying passage opened inside the connecting pipe is outwardly expanding from top to bottom.

[0011] Through the above technical solution, the water flow is converged when passing through, thereby increasing the water flow intensity and preventing internal blockage.

[0012] Furthermore, the structure of the extension tube is the same as the structure of the other side of the threaded tube.

[0013] Through the above technical solution, adjustment of different spacing values ​​can be achieved, with better adaptability.

[0014] Furthermore, the limiting tube is made of spring steel, the interior of which is a spherical groove that fits the spherical sleeve, and the outer surface of the top of the limiting tube is provided with a reinforcement groove for clamping the pipe clamp.

[0015] Through the above technical solution, during installation, by using a pipe clamp for reinforcement, the opening at the top of the limiting tube is clamped on the internal spherical sleeve to prevent internal water seepage, and at the same time the angle of the ball pin is fixed.

[0016] Furthermore, the horizontal height of the bottom wall of the bending groove is not lower than the horizontal height of the center axis of the ball pin.

[0017] The above technical solution can prevent the clamping effect on the ball pin from being affected.

[0018] Furthermore, a group of steel balls distributed at equal distances are installed on the inner wall of the spherical sleeve.

[0019] Through the above technical solution, it is ensured that there is a certain gap between the outer surface of the universal ball tube and the inner wall of the spherical sleeve to allow water to flow through.

[0020] Compared with the prior art, the utility model has the following beneficial effects:

[0021] 1. When two pipes are bent and connected, compared with the existing structure, the resistance to the bend can only form an "eight" shape (such as Figure 4 As shown), the bending angle can be increased to reduce obstruction, thereby reducing the distance between the two pipes and preventing waste of space between the pipes (as shown Figure 5 shown);

[0022] 2. The length can be adjusted through the thread to adapt to the distance between the two pipes, without the need to use additional extension tubes for assembly and adaptation. BRIEF DESCRIPTION OF THE DRAWINGS

On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "set" should be understood in a broad sense, for example, they can be fixedly connected or set, or detachably connected or set, or integrally connected or set. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] Example 1

[0032] like Figure 1-3 As shown, this embodiment provides an adjustable angle joint for installing a water pipe network pipeline, including a fixed flange 1 and a connecting mechanism, the connecting mechanism includes a connecting pipe 4 fixedly connected to the output end of the fixed flange 1, a conveying passage 41 is opened inside the connecting pipe 4, and it is outwardly expanded from top to bottom, so that the water flow passing through it is first converged and then output, which has the function of increasing the water flow intensity, preventing the accumulation of internal impurities and causing the connection bending part to be blocked, a spherical sleeve 3 is fixed on the top of the connecting pipe 4, a universal ball tube 8 is sleeved inside the spherical sleeve 3, and a conveying passage 81 is opened inside the universal ball tube 8. It should be noted that the universal ball tube 8 is formed by integrating a ball pin and a straight tube, and the conveying passage 81 is opened at the vertical center axis of the ball pin and the straight tube, so that the ball pin can rotate inside the spherical sleeve 3, thereby realizing the bending and connecting operation between the two pipes;

[0033] The center of the outer surface of the spherical sleeve 3 is connected to the conveying channel 81 through the inner through hole 31, and the outer surface of the universal ball tube 8 away from the spherical sleeve 3 is provided with a threaded layer 5, and the threaded sleeve is provided with a threaded tube 6 at the threaded layer 5. The end of the threaded tube 6 away from the connecting tube 4 is fixedly connected with an extension tube 7, so that the distance between the fixed extension tube 7 and the universal ball tube 8 is increased by rotating the threaded tube 6, thereby achieving the operation of increasing, and the extension tube 7 is fixedly connected with another pipe through the connecting mechanism and the fixed flange 1, thereby realizing the bending connection processing of the two pipes;

[0034] The outside of the spherical sleeve 3 is also sleeved with a matching limiting tube 2, which is made of spring steel, and its interior is a spherical groove that fits the spherical sleeve 3, and the outer surface of the top of the limiting tube 2 is provided with a reinforcement groove for clamping the U-shaped pipe clamp, so that the opening at the top of the limiting tube 2 clamps the internal spherical sleeve 3 to prevent internal water seepage, and at the same time fixes the angle of the ball pin, and can also be equipped with a sealing gasket to increase the anti-seepage effect. A bearing 22 is fixed to the bottom of the inner ring of the limiting tube 2, and the inner ring of the bearing 22 is fixed to the outer surface of the output end of the fixed flange 1. Its function is that the bending groove 21 can be rotated to different positions by rotation, which is convenient for adapting to the straight pipe. The outer edge of the limiting tube 2 is provided with a universal ball tube 8 The adapted bending groove 21, in detail, the horizontal height of the inner bottom wall of the bending groove 21 is not lower than the horizontal height of the center axis of the ball pin to prevent the opening from being too low to affect the clamping effect of the ball pin. At the same time, in order to ensure that there is a certain gap between the outer surface of the universal ball tube 8 and the inner wall of the spherical sleeve 3 to allow water to flow through, a group of equidistantly distributed steel balls (distributed in a circular ring shape) are also installed on the inner wall of the spherical sleeve 3. The steel balls are embedded in the inside of the card slot opened on the inner wall of the spherical sleeve 3. The aperture value of the opening opened in the card slot for the steel balls to pass through is smaller than the diameter value of the steel balls to prevent the steel balls from falling off. At the same time, the horizontal position of the steel balls should be higher than the center of the universal ball tube 8 to prevent the steel balls from being stuck in the inside of the conveying pipe 81 when the universal ball tube 8 rotates.

[0035] In this embodiment, when the ports of two pipes need to be connected at an angle, the fixed flange 1 is fixedly connected to the first pipe, and then the straight pipe is adjusted according to the bending angle, and the limiting pipe 2 is rotated so that the bending groove 21 is located at the bottom of the straight pipe, and then the reinforcement groove is reinforced with a pipe clamp, and finally the extension pipe 7 is fixedly connected to the second pipe (by welding or connecting parts).

[0036] Example 2

[0037] The difference from Example 1 is that the structure of the extension tube 7 is the same as the universal ball tube 8, and the spherical sleeve 3, the connecting tube 4, and the limiting tube 2 are installed in sequence until it is fixedly connected with another fixed flange 1. It can be understood as being mirrored along the threaded tube 6, and the only difference is that it is fixedly connected with the threaded tube 6 (due to the same structure, Figure 1(not shown in the figure), when two pipes are bent and connected, the distance between the two pipes can be reduced by bending to a right angle.

[0038] In this embodiment, when the ports of two pipes need to be connected with double angles (ie, C-shaped), the installation principle is the same as in Embodiment 1, except that the two fixed flanges 1 are fixedly connected with the two pipes respectively.

[0039] It should be noted that the structure described in the utility model can be implemented in a variety of different forms and is not limited to the described embodiments. Any equivalent transformations made by ordinary technicians in this field using the contents of the utility model specification and drawings, or directly or indirectly applied to other related technical fields, such as the loading and unloading of other items, are included in the protection scope of the utility model.
