UTILITY MODEL CONTENTS

[0003] Based on the technical problem that the existing water pipe buffering mechanism elasticity drops to cause buffering to be poor and inconvenient to disassemble and reassemble, the utility model provides an anti-impact PE water supply pipe.

[0015] The beneficial effects of the present invention are:

[0016] By setting a buffer device, when the water pipe is impacted, the fixed column applies pressure to the sliding plate, causing the sliding plate to squeeze the fixed spring, and the fixed spring to expand and contract, thereby buffering the impact received by the sliding plate. The sliding plate drives the connecting rod to move, and the connecting rod drives the first piston plate to move. Hydraulic oil is filled between the first piston plate and the second piston plate, so that the impact received by the first piston plate is buffered to a certain extent.

After multiple stages of buffering, the impact received by the water pipe is greatly reduced. When disassembling and assembling the limit ring, the limit screw ring is removed from the limit screw, and the limit screw is moved out of the fixed round rod. The limit ring can be separated, which is convenient for replacement of the entire mechanism and maintains long-term use, thereby achieving the effect of ensuring long-term use of the buffer mechanism and convenient installation.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-Figure 3 A shock-resistant PE water supply pipe includes a mounting seat 1 and a mounting cylinder 2. In order to ensure that the water pipe 713 is buffered to a certain extent when it is impacted, a buffer device is provided inside the mounting cylinder 2. The buffer device includes a buffer spring 3, a first piston plate 4, a second piston plate 5, a connecting rod 6 and a sliding plate 7. When the sliding plate 7 is squeezed, the connecting rod 6 drives the first piston plate 4 to move downward. When the second piston plate 5 is squeezed, it squeezes the buffer spring 3, and the buffer spring 3 contracts after being squeezed.

[0023] In order to ensure that the impact received by the first piston plate 4 is better buffered, the mounting cylinder 2 is fixedly installed inside the mounting seat 1, the upper surface of the mounting cylinder 2 is fixedly installed with a fixing cylinder 21, and the buffer spring 3 is fixedly installed on the lower bottom wall of the mounting cylinder 2. The first piston plate 4 and the second piston plate 5 are both slidably inserted into the interior of the mounting cylinder 2, and the first piston plate 4 is located above the second piston plate 5. Hydraulic oil is filled between the first piston plate 4 and the second piston plate 5, so that the impact received by the first piston plate 4 is better buffered.

[0024] In order to ensure that the impact of the second piston plate 5 is buffered, the second piston plate 5 is fixedly mounted on the upper end of the buffer spring 3, the connecting rod 6 is fixedly mounted on the upper surface of the first piston plate 4, the sliding plate 7 is slidably inserted into the interior of the fixed cylinder 21, and the lower surface of the sliding plate 7 is fixedly connected to the upper surface of the connecting rod 6. The buffer spring 3 buffers the impact of the second piston plate 5, and the sliding plate 7 is stuck in the interior of the fixed cylinder 21 and slides, driving the connecting rod 6 to move.

[0025] In order to ensure that the impact received by the sliding plate 7 is buffered, a fixed spring 71 is fixedly installed on the lower surface of the sliding plate 7, and the lower end of the fixed spring 71 is fixedly connected to the lower end of the inner wall of the fixed cylinder 21. A fixed column 72 is fixedly installed on the upper surface of the sliding plate 7, and a limiting ring 73 is fixedly installed on the upper end of the fixed column 72. When the sliding plate 7 moves, the fixed spring 71 expands and contracts to buffer the impact received by the sliding plate 7.

[0026] In order to facilitate the fixation of the water pipe 713 and facilitate disassembly and assembly, the limiting ring 73 includes an upper semi-ring body 74 and a lower semi-ring body 75. The outer surface of the lower semi-ring body 75 is fixedly connected to the upper surface of the fixing column 72, and the lower surface of the upper semi-ring body 74 is in contact with the upper surface of the lower semi-ring body 75. The left and right sides of the upper semi-ring body 74 and the lower semi-ring body 75 are fixedly installed with mounting plates 76. The upper semi-ring body 74 and the lower semi-ring body 75 constitute a limiting ring 73, which plays the role of fixing the water pipe 713 and is also convenient for disassembly and assembly.

[0027] When the locking cam 711 is unlocked, the locking cam 712 is unlocked and the winch 73 is unlocked, so that the winch 73 can be unlocked easily.

[0028] When the lever 71 is unlocked, the locking lever 78 is unlocked, and the locking lever 78 is unlocked, so that the locking lever 78 is unlocked, and the impact of the first and second locking levers 7 is reduced.

[0029] Working principle: when the water pipe 713 is impacted, the fixed column 72 applies pressure to the sliding plate 7, causing the sliding plate 7 to squeeze the fixed spring 71, and the fixed spring 71 expands and contracts to cushion the impact on the sliding plate 7, and the sliding plate 7 drives the connecting rod 6 to move, and the connecting rod 6 drives the first piston plate 4 to move, and hydraulic oil is filled between the first piston plate 4 and the second piston plate 5, so that the impact on the first piston plate 4 is cushioned to a certain extent. When the hydraulic oil impacts, the second piston plate 5 moves, and the buffer spring 3 cushions the impact of the second piston plate 5. After multiple stages of buffering, the impact on the water pipe 713 is greatly reduced. When disassembling the limit ring 73, the limit screw ring 710 is removed from the limit screw 79, and the limit screw 79 is moved out of the fixed round rod 77, so that the limit ring 73 can be separated, which is convenient for replacement of the entire mechanism and maintains long-term use.

[0030] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
