Technical Field

[0001] The utility model relates to the field of water supply pipe fittings, in particular to a water supply terminal pipe fitting. Background Art

[0002] With the progress of society and the development of urbanization, the number and scale of high-rise buildings are increasing, and the requirements for fire safety are becoming higher and higher. As one of the important safety facilities in high-rise buildings, the fire water supply system, its design and the rational selection of system components are of great significance to ensuring the safety of life and property. Pipes, fittings and valves are key components for water transmission, control and regulation, and the rational and compliant selection is very important.

[0003] The existing water supply pipe fittings still have the following problems when in use: Due to the high-speed water flow passing through the bends of the existing pipes, the water flow will have a large impact on the opposite pipe wall. During the impact process, most of the water flow continues to flow along the pipe, and part of the water flow will flow back and collide with the subsequent water flow, resulting in a reduced service life of the entire pipe fitting.

[0004] Therefore, it is necessary to invent a water supply terminal pipe fitting to solve the above problems. Utility Model Content

[0005] The purpose of the present utility model is to provide a water supply terminal pipe fitting to solve the problem raised in the above background technology that the existing bends of the pipes will have a large impact on the pipe wall due to the high-speed water flow passing through. During the impact process, most of the water flow continues to flow along the pipe, and part of the water flow will flow back and collide with the subsequent water flow, resulting in a reduced service life of the entire pipe fitting.

[0006] In order to achieve the above-mentioned object, the present invention provides the following technical solution: a water supply terminal pipe fitting, comprising a pipe body, the pipe body being provided with two ports, wherein a sleeve is threadedly connected to the water inlet port near the bend, a connecting plate is fixedly connected to the inner wall of the sleeve, the top of the connecting plate is flush with the top of the sleeve, a shock-absorbing plate is movably mounted on the bottom of the sleeve, and the shock-absorbing plate is near the bend of the pipe body, and further comprising:

[0007] A connecting assembly, wherein the top of the shock-absorbing plate is fixedly connected to a mounting rod, and the mounting rod can move inside a sliding groove reserved at the bottom of the sleeve, and is used for rotational connection between the shock-absorbing plate and the sleeve;

[0008] A limiting assembly, wherein the bottom outer wall of the shock-absorbing plate is fixedly connected to a limiting block, and the limiting block can move inside a limiting groove reserved inside the pipe body, so as to facilitate the subsequent linear up and down movement of the shock-absorbing plate, avoid unnecessary rotational friction between the outer wall of the shock-absorbing plate and the inner wall of the pipe body, thereby extending the service life of the shock-absorbing plate.

[0009] Preferably, the outer wall of the sleeve is provided with a section of thread, and the thread is matched with the thread groove thread. The thread groove is arranged on the inner wall of the water inlet port. The height of the thread groove is the same as the height of the thread, which promotes the threaded connection between the sleeve and the water inlet port of the pipe body, and at the same time ensures the stability of the connection between the sleeve and the water inlet port of the pipe body.

[0010] Preferably, the shock-absorbing plate is cylindrical, and the outer wall of the shock-absorbing plate is fitted and connected to the inner wall of the pipe at the water inlet port of the pipe body. The shock-absorbing plate is installed in fits with the inner wall of the pipe body. Under the action of the shock-absorbing plate, the impact force of the water flow on the bending part of the pipe body is reduced, thereby extending the service life of the entire bend body.

[0011] Preferably, the inner wall of the shock-absorbing plate is a smooth surface.

[0012] Preferably, the number of the mounting rods is four, and the four mounting rods are fixedly connected to the top of the shock absorbing plate in a circular shape with equal angles;

[0013] The installation rods are in the shape of "7" in different directions.

[0014] Preferably, the outer wall of the mounting rod is in contact with and slidably connected to the inner wall of the sliding groove. The sliding groove is an annular groove with an open bottom. The cross-section of the sliding groove is in the shape of a "7", which ensures that the sleeve and the shock-absorbing plate are rotatably connected while ensuring that the connection between the sleeve and the shock-absorbing plate will not fall off and separate.

[0015] Preferably, there are two limit blocks, and the two limit blocks are symmetrically arranged with reference to the central axis of the shock-absorbing plate as the axis of symmetry;

[0016] The limiting block is square.

[0017] Preferably, the top of the limit groove is open, and the inner wall of the limit groove is in contact with the outer wall of the limit block and is connected by sliding up and down, so that the limit blocks preset on both sides of the shock-absorbing plate can enter the interior of the pipeline body through the open limit groove without affecting the tightness of the threaded connection between the sleeve and the water inlet port.

[0018] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0019] 1. This utility model installs a shock-absorbing plate inside the pipe body. When water flows through the bend of the bend, the impact of the water flow on the bend of the pipe body can be absorbed by the shock-absorbing plate, thereby extending the service life of the entire bend.

[0020] 2. At the same time, twisting the connecting plate drives the sleeve that is threadedly connected to the pipe body to leave the water inlet port of the pipe body. Since the sleeve is rotatably connected to the shock-absorbing plate, and the limit block fixedly connected to the bottom of the shock-absorbing plate moves up and down in the limit groove reserved inside the pipe body, the shock-absorbing plate can still be driven to move up and down and leave the inside of the pipe body when the sleeve is rotated, avoiding unnecessary rotational friction between the outer wall of the shock-absorbing plate and the inner wall of the pipe body, thereby extending the service life of the shock-absorbing plate.

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] The utility model provides Figure 1-4 The water supply terminal pipe fitting shown in the figure includes a pipe body 1, which is provided with two ports. The water inlet port 2 near the bend is threadedly connected to a sleeve 3. The inner wall of the sleeve 3 is solidly connected to a connecting plate 8. The top of the connecting plate 8 is flush with the top of the sleeve 3, which facilitates the rotation of the sleeve 3 by turning the connecting plate 8. A shock-absorbing plate 6 is movably installed at the bottom of the sleeve 3, and the shock-absorbing plate 6 is close to the bend of the pipe body 1. It also includes:

[0030] Connecting assembly 7, the top of the shock absorbing plate 6 is fixedly connected with a mounting rod 71, and the mounting rod 71 can move inside the sliding groove 72 reserved at the bottom of the sleeve 3, for rotating connection between the shock absorbing plate 6 and the sleeve 3;

[0031] The limiting component 9, the bottom outer wall of the shock-absorbing plate 6 is fixedly connected to the limiting block 91, and the limiting block 91 can move inside the limiting groove 92 reserved inside the pipe body 1, so as to facilitate the subsequent linear up and down movement of the shock-absorbing plate 6, avoid unnecessary rotational friction between the outer wall of the shock-absorbing plate 6 and the inner wall of the pipe body 1, thereby extending the service life of the shock-absorbing plate 6.

[0032] The outer wall of the sleeve 3 is provided with a section of thread 4, which is threadedly matched with the thread groove 5. The thread groove 5 is arranged on the inner wall of the water inlet port 2. The height of the thread groove 5 is the same as the height of the thread 4, which promotes the threaded connection between the sleeve 3 and the water inlet port 2 of the pipe body 1, and at the same time ensures the stability of the connection between the sleeve 3 and the water inlet port 2 of the pipe body 1.

[0033] The shock-absorbing plate 6 is cylindrical, and the outer wall of the shock-absorbing plate 6 is fitted and connected to the inner wall of the pipe at the water inlet port 2 of the pipe main body 1. The shock-absorbing plate 6 is installed in fits with the inner wall of the pipe main body 1. Under the action of the shock-absorbing plate 6, the impact force of the water flow on the bending part of the pipe main body 1 is reduced, thereby extending the service life of the entire bend main body 1.

[0034] The inner wall of the shock absorbing plate 6 is a smooth surface.

[0035] There are four mounting rods 71, and the four mounting rods 71 ​​are fixedly connected to the top of the shock absorbing plate 6 in a circular shape with equal angles;

[0036] The mounting rod 71 is in the shape of a "7" with different directions.

[0037] The outer wall of the mounting rod 71 is fitted with and slidably connected to the inner wall of the sliding groove 72. The sliding groove 72 is an annular groove with an open bottom. The cross-section of the sliding groove 72 is in the shape of a "7", which ensures that the sleeve 3 and the shock-absorbing plate 6 are rotatably connected while ensuring that the sleeve 3 and the shock-absorbing plate 6 will not fall off and separate.

[0038] There are two limit blocks 91, and the two limit blocks 91 are symmetrically arranged with reference to the central axis of the damping plate 6 as the symmetry axis. When the limit blocks 91 match the limit grooves 92, the damping plate 6 can move linearly up and down, thereby preventing the rotation of the damping plate 6 from causing friction to the damping plate 6 and affecting the service life of the damping plate 6.

[0039] The limiting block 91 is square.

[0040] The top of the limiting groove 92 is open, which makes it convenient for the limiting block 91 to enter the interior of the limiting groove 92 through the opening, and the inner wall of the limiting groove 92 is in contact with the outer wall of the limiting block 91 and is connected by sliding up and down, which makes it convenient for the limiting blocks 91 preset on both sides of the shock-absorbing plate 6 to enter the interior of the pipe body 1 through the open limiting groove 92, and at the same time will not affect the tightness of the threaded connection between the sleeve 3 and the water inlet port 2.

[0041] Working principle: When using a water supply terminal pipe fitting, first, when installing the shock-absorbing plate 6, the limit blocks 91 fixedly connected on both sides of the outer wall of the bottom of the shock-absorbing plate 6 are installed into the limit groove 92 through the notches opened at the top of the limit groove 92, and the shock-absorbing plate 6 is pressed downward so that the lower end of the sleeve 3 rotatably connected to the upper end of the shock-absorbing plate 6 contacts the water inlet port 2, and then the sleeve 3 is rotated. The sleeve 3 is threadedly connected to the water inlet port 2. When the sleeve 3 is rotated, the sleeve 3 rotates and descends synchronously, which makes it convenient to install the sleeve 3 and the entire shock-absorbing plate 6 into the interior of the pipeline body 1. At the same time, the sleeve 3 is rotatably connected to the shock-absorbing plate 6, so that the shock-absorbing plate 6, which is limited to only move up and down, does not affect the rotation of the sleeve 3;

[0042] When the pipe main body 1 and the shock-absorbing plate 6 are subsequently inspected and repaired, the sleeve 3 threadedly connected to the pipe main body 1 is driven by twisting the connecting plate 8 to rotate away from the water inlet port 2 of the pipe main body 1 threadedly connected thereto. At the same time, the sleeve 3 and the shock-absorbing plate 6 are rotationally connected, and the limit blocks 91 fixedly connected to the two side walls of the shock-absorbing plate 6 are slid up and down inside the limit grooves 92 reserved inside the pipe main body 1. In this way, when the sleeve 3 is rotated to make the sleeve 3 move upward, the upward movement of the shock-absorbing plate 6 is synchronously mobilized. Under the restriction matching of the limit blocks 91 and the limit grooves 92, the shock-absorbing plate 6 moves upward in a straight line, which can avoid unnecessary rotational friction between the outer wall of the shock-absorbing plate 6 and the inner wall of the pipe main body 1, thereby extending the service life of the shock-absorbing plate 6. The shock-absorbing plate 6 can be directly taken out later.

[0043] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
