Description

Technical Field

[0001] The utility model relates to the technical field of connecting pipe fittings, and particularly relates to a crimping type connecting pipe fitting with a water leakage detection function. Background Art

[0002] In the existing technical field of water supply pipelines, crimping type connecting pipe fittings are a relatively commonly used type of pipe connectors. However, a common problem that exists uniformly during the installation of pipe connectors is whether the pipe fittings are installed in place and whether water leakage will occur after water is passed through.

[0003] Since the water pipe will be covered by the external structure of the crimping type connecting pipe fitting after installation, when a water leakage phenomenon occurs, it is difficult for a water worker to find the leakage point, resulting in repeated installation and disassembly of the crimping type connecting pipe fitting, reducing work efficiency, and the sealing of the crimping type connecting pipe fitting may also fail after multiple repeated installations and disassembly.

[0004] In view of this, the present utility model is specifically proposed. Summary of the Utility Model

[0005] The purpose of the present utility model is to provide a crimping type connecting pipe fitting with a water leakage detection function, which can quickly judge whether the crimping type connecting pipe fitting leaks water and improve work efficiency.

[0006] The embodiments of the present utility model are implemented as follows:

[0007] In a first aspect, the present utility model provides a crimping type connecting pipe fitting with a water leakage detection function, including a pipe fitting body, a transparent blocking part, a color-changing part, and a pressing part.

[0008] The pipe fitting body includes a core part for inserting into a pipe. A connecting clamping groove is provided at one end of the core part far away from the opening. The transparent blocking part is sleeved on one end of the core part close to the connecting clamping groove. The transparent blocking part includes a main body part, a first connecting end, and a second connecting end. The first connecting end is fixed to the connecting clamping groove, and the main body part is spaced from the core part. A color-changing part is fixed on the surface of the core part corresponding to the main body part. The color-changing part is configured to change color when encountering water. The pressing part is sleeved on the surface of the core part and one end thereof is fixed to the second connecting end of the transparent blocking part.

[0009] In an optional embodiment, the color-changing part includes a fixing layer, a base color layer, and a color-changing layer arranged in sequence in a direction away from the core part. The fixing layer is fixedly connected to the core part. The base color layer is configured to display a color. The color-changing layer is configured to change from a colored state to a transparent state after contacting water, and when the color-changing layer is in a non-transparent state, its color is different from that of the base color layer.

[0010] In an optional embodiment, the fixing layer is an adhesive layer, and the fixing layer is connected to the core part by bonding.

[0011] In an optional embodiment, the color-changing element is a ring-shaped structure or a plurality of block-shaped structures arranged at intervals.

[0012] In an optional embodiment, the main body of the transparent blocking portion is further provided with a drainage hole, and the drainage hole is arranged corresponding to the color-changing component.

[0013] In an optional embodiment, the number of the drainage holes is 2 to 8.

[0014] In an optional embodiment, the pressing member is further provided with an observation hole, and the observation hole is located close to an end where the pressing member is connected to the transparent blocking portion.

[0033] First Embodiment

[0034] Please refer to Figure 1 and Figure 2 , this embodiment provides a press-fit connection pipe fitting 100 with a water leakage detection function, which includes a pipe fitting body 110, a transparent blocking part 120, a color-changing part 130, a sealing part 140, and a pressing part 150.

[0035] Among them, the pipe fitting body 110 is a tubular structure with both ends penetrating, and the internally penetrating channel is used to transport materials. Multiple ribs and grooves are provided on the outer wall surface of the channel to facilitate contact with the pipe 300 or clamping with other structures, so as to realize the fixed connection of the pipe 300.

[0036] The pipe fitting body 110 includes a core part 111 for inserting the pipe 300. When the pipe 300 is connected to the press-fit connection pipe fitting 100, the inner wall surface of the pipe 300 is in direct contact with the outer wall surface of the core part 111. Therefore, the maximum diameter on the outer wall surface of the core end needs to be smaller than the inner diameter of the pipe 300.

[0037] Since the fitting body 110 is a tubular structure with both ends penetrating, both ends thereof have openings, so that the material in the pipeline 300 can be conveyed through the openings to the inside of another pipeline 300 or the inside of the equipment after the pipeline 300 is sleeved on the fitting body 110.

[0038] It can be understood that since the function of the crimping connection fitting 100 is a structure for connecting two pipelines 300 or connecting the pipeline 300 with the equipment, therefore, a crimping connection fitting 100 should have two sets of structures capable of connecting with the pipeline 300 or the equipment, including a transparent blocking part 120, a color-changing part 130, a sealing part 140 and a pressing part 150. The two sets of the above structures are respectively located at both ends of the crimping connection fitting 100. And the fitting body 110 includes two core parts 111. Hereinafter, the connection relationship between one of the core parts 111 and the structures of the transparent blocking part 120, the color-changing part 130, the sealing part 140 and the pressing part 150 on its surface will be taken as an example for description.

[0039] A connection card slot 112 is arranged at one end of the core part 111 far away from the opening, and the transparent blocking part 120 is sleeved on one end of the core part 111 close to the connection card slot 112; the transparent blocking part 120 includes a main body part 121, a first connection end 122 and a second connection end 123. The first connection end 122 is fixed to the connection card slot 112, and the main body part 121 is arranged at an interval from the core part 111. A color-changing part 130 is fixed on the surface of the core part 111 corresponding to the main body part 121. The pressing part 150 is sleeved on the surface of the core part 111 and one end thereof is fixed to the second connection end 123 of the transparent blocking part 120, and the opposite end extends to cover the opening of the fitting body 110.

[0040] Therefore, on the surface of the core part 111, through the sleeving of the transparent blocking part 120 and the pressing part 150, the whole core part 111 can be covered. In addition, since except for the first connection end 122 connected to the core part 111 of the transparent blocking part 120 which contacts the core part 111, the rest parts are arranged at intervals from the core part 111, so the pressing part 150 fixed to the second connection end 123 of the transparent blocking part 120 is also arranged at an interval from the core part 111. Therefore, the interval between the transparent blocking part 120 and the pressing part 150 and the core part 111 can be used to accommodate the pipeline 300. By using a crimping tool 200 to squeeze the pressing part 150, the pressing part 150 squeezes the pipeline 300 inside it, so that the pipeline 300 is in close contact with the surface of the core part 111, and the teeth conventionally designed on the surface of the core part 111 can also bite tightly on the pipeline 300 to realize the tight connection between the pipeline 300 and the core part 111.

[0041] Further, in order to ensure the tight connection between the pipeline 300 and the core part 111, a sealing groove 113 is further provided on the outer wall surface of the core part 111, and a sealing member 140 is accommodated in each sealing groove 113. In this embodiment, the sealing member 140 is an O-ring. The number of O-rings is three, so the three sealing grooves 113 are evenly spaced on the core and are all provided on the core corresponding to the pressing member 150 to avoid affecting the judgment of water leakage of the color-changing ring and the transparent barrier.

[0042] Please refer to Figure 3 , in this embodiment, the color-changing member 130 is a color-changing ring, and the color-changing member 130 is sleeved on the surface of the core part 111. In other embodiments, the color-changing member 130 can also be a separate color block, such as a square color block, a triangular color block or a circular color block, etc. The separate color blocks are evenly spaced and fixed on the surface of the core part 111 to form a block structure.

[0043] In this embodiment, the color-changing member 130 includes a fixing layer 131, a base color layer 132 and a color-changing layer 133 arranged in sequence along the direction away from the core part 111.

[0044] Among them, the fixing layer 131 is fixedly connected to the core part 111. In this embodiment, the fixing layer 131 is an adhesive layer, and the connection method between the fixing layer 131 and the core part 111 is bonding. In other embodiments, the fixing layer 131 can also be made of materials such as silica gel, and the connection method with the core part 111 can be interference fit by controlling the friction force between the two.

[0045] The base color layer 132 is configured to display a color, such as warning colors such as yellow, red, blue and green. The base color layer 132 can be made of a colored film or paper; or it can also be coated with a colored paint.

[0046] The color-changing layer 133 is configured to change from a colored state to a transparent state after contacting water. Therefore, after contacting water, the color-changing member 130 can display the color of the base color layer 132. When not contacting water, the color-changing member 130 displays the color of the color-changing layer 133. Therefore, when the color-changing layer 133 is non-transparent, its color is different from that of the base color layer 132. For example, the color-changing layer 133 can change from milky white to transparent.

[0047] The three-layer structure of the color-changing member 130 can be prepared from existing materials, such as plastics, paper and water-based inks.

[0048] In this embodiment, the main body part 121 of the transparent barrier part 120 is also provided with a water discharge hole 124, and the water discharge hole 124 is arranged corresponding to the color-changing member 130 for timely discharging the internal water leakage.

[0049] In this embodiment, the number of the water discharge holes 124 is two. In other embodiments, the number of the water discharge holes 124 may also be three, four, five, six, seven or eight.

[0050] In this embodiment, in order to facilitate observing whether the pipe 300 is properly installed in the press-connection fitting 100, an observation hole 151 is further provided on the pressing member 150. The observation hole 151 is located at one end of the pressing member 150 close to the connection with the transparent blocking portion 120. The position of the pipe 300 is observed through the observation hole 151 to assist in the installation of the pipe 300 and avoid water leakage caused by improper installation of the pipe 300.

[0051] In this embodiment, the number of the observation holes 151 is one. In other embodiments, the number of the observation holes 151 may also be two, three, four, five or six.

[0052] A press-connection fitting 100 with a water leakage detection function provided in this embodiment has the following installation process and working principle:

[0053] Please refer to Figure 1 and Figure 4 , and the color-changing member 130 is sleeved on the surface of the core portion 111 at one end close to the connection slot 112. The fixing layer 131 of the color-changing member 130 is bonded to the core portion 111. Then the transparent blocking portion 120 is sleeved on the surface of the core portion 111, and the first connection end 122 of the transparent blocking portion 120 is snapped into the connection slot 112, so that the transparent blocking portion 120 and the color-changing layer 133 of the color-changing member 130 are arranged at intervals. Then the pressing member 150 is fixed to the second connection end 123 of the transparent blocking portion 120, so that a gap for accommodating the pipe 300 is formed among the pressing member 150, the transparent blocking portion 120 and the core portion 111. After the sealing member 140 is installed in the sealing groove 113, the pipe 300 is inserted into the gap formed among the pressing member 150, the transparent blocking portion 120 and the core portion 111, and it is observed through the observation hole 151 whether the pipe 300 is inserted to the bottom. If the core portion 111 at the observation hole 151 is not completely covered by the pipe 300, it means that it is not properly installed and needs to be further inserted. When the core portion 111 at the observation hole 151 is completely covered by the pipe 300, a pressing tool 200 is used to apply pressure to the pressing member 150. The pressing member 150 moves towards the direction close to the core portion 111, so that the pipe 300 contacts the core portion 111, and the pipe 300 is clamped onto the teeth of the core portion 111 for sealing and fixing.

[0054] Please refer to Figure 4 and Figure 5After the pipe 300 is installed, a water flow test is performed. When there is a gap between the pipe 300 and the core part 111, water will enter from the gap between the pipe 300 and the core part 111 and contact the color-changing member 130 in the gap. The color-changing layer 133 of the color-changing member 130 becomes transparent when exposed to water, showing the color of the base layer 132. The construction personnel can directly observe the color change through the transparent blocking part 120 and turn off the water in time to reinstall and fix it. The water in the gap can be discharged through the drain hole 124 on the transparent blocking part 120 to prevent the accumulation of water pressure from affecting the function of the compression type connection pipe fitting 100.

[0055] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
