Description

Technical Field

[0001] The utility model relates to the technical field of fluid systems, and particularly relates to a connection component for a fluid system. Background Art

[0002] A pre-filter is a device for initially filtering water and is a commonly used device in fluid systems. When in use, generally, the connecting water pipe needs to be cut off, and the pre-filter is installed in the middle of the cut position of the connecting water pipe. However, since the pre-filter is mass-produced, the lengths of its inlet pipe and outlet pipe are fixed. When cutting the connecting water pipe, it is generally difficult to accurately cut it to the appropriate length. Therefore, when connecting the pre-filter, there are often situations where the pipe is cut too long and needs to be connected or the pipe is cut too short and needs to be cut further. Thus, it is not convenient to use and reduces the connection efficiency.

[0003] Therefore, a connection component for a fluid system is proposed. Content of the Utility Model

[0004] To solve the problems existing in the prior art, the utility model provides a connection component for a fluid system.

[0005] The utility model specifically adopts the following technical solutions to achieve the above purposes:

[0006] A connection component for a fluid system includes a water pipe pre-filter, a first connection pipe, and a second connection pipe. The water pipe pre-filter is arranged between the first connection pipe and the second connection pipe. An inlet pipe and a drain pipe are arranged on the water pipe pre-filter. Connection components for connecting the second connection pipe and the first connection pipe are respectively arranged on the inlet pipe and the drain pipe. The connection component includes a length adjustment member and a connection limit member. The length adjustment member includes a rotating seat arranged on the inlet pipe and the drain pipe. A threaded sleeve is rotatably arranged on the rotating seat. A threaded casing is in threaded connection with the threaded sleeve. Connection rings are arranged at one ends of the inlet pipe and the drain pipe. A corrugated pipe is arranged on one side of the connection ring. The corrugated pipe is arranged inside the threaded sleeve.

[0007] Further, the connection limit member includes a connection sleeve arranged at one end of the corrugated pipe. The connection sleeve is connected with the threaded casing.

[0008] Further, a connection slot is opened on the connection sleeve. The inner arcs of the first connection pipe and the second connection pipe are fitted with the connection slot.

[0009] Further, two extrusion limiting arc-shaped plates are slidably arranged inside the connection slot, and the inner arc of the extrusion limiting arc-shaped plate fits the outer arc surfaces of the first connection pipe and the second connection pipe.

[0010] Further, two connection bolts are threadedly connected to the connection sleeve, and the extrusion limiting arc-shaped plate is connected to the connection bolt.

[0011] Further, there is a certain gap between the corrugated pipe and the threaded sleeve.

[0012] The beneficial effects of the present utility model are as follows:

[0013] By means of the length adjustment member provided in the present utility model, the lengths of the water inlet pipe and the drain pipe of the water pipe pre-filter can be adjusted. Therefore, when installing and connecting them, the lengths of the water inlet pipe and the drain pipe can be conveniently and quickly adjusted according to the distance from the first connection pipe to the second connection pipe. Thus, it can be avoided that the length cut from the first connection pipe to the second connection pipe is too long or too short, which affects the installation of the water pipe pre-filter, and further ensures the installation and connection efficiency, improves its applicability, and makes the connection more convenient and fast.

[0023] Such as Figures 1-4As shown in the figure, a connection component for a fluid system includes a water pipe pre-filter 1, a first connecting pipe 4, and a second connecting pipe 5. The water pipe pre-filter 1 is arranged between the first connecting pipe 4 and the second connecting pipe 5. An inlet pipe 2 and a drain pipe 3 are arranged on the water pipe pre-filter 1. Connection components 6 for connecting the second connecting pipe 5 and the first connecting pipe 4 are respectively arranged on the inlet pipe 2 and the drain pipe 3. The connection component 6 includes a length adjustment member 7 and a connection limit member 8. The length adjustment member 7 includes a rotating seat 701 arranged on the inlet pipe 2 and the drain pipe 3. A threaded sleeve 702 is rotatably arranged on the rotating seat 701. A threaded casing 703 is connected to the threaded sleeve 702 by internal threads. Connection rings 201 are arranged at one ends of the inlet pipe 2 and the drain pipe 3. A corrugated pipe 704 is arranged on one side of the connection ring 201. The corrugated pipe 704 is arranged inside the threaded sleeve 702. Specifically, during use, according to the cut length between the first connecting pipe 4 and the second connecting pipe 5, the length adjustment member 7 can be used to adjust the lengths of the inlet pipe 2 and the drain pipe 3, so that it is convenient to insert the first connecting pipe 4 and the second connecting pipe 5 into the inside of the connection slot 802. Then, the connection limit member 8 can be used to fix the first connecting pipe 4 and the second connecting pipe 5 inside the connection slot 802, thereby realizing the connection of the pipes. When adjusting the lengths of the inlet pipe 2 and the drain pipe 3, under the action of the threaded sleeve 702 and the threaded casing 703, the water pipe pre-filter 1 can maintain a straight state, thus avoiding the corrugated pipe 704 from being bent to hinder the flow of water.

[0024] As Figure 4 shown, the connection limit member 8 includes a connection sleeve 801 arranged at one end of the corrugated pipe 704. The connection sleeve 801 is connected to the threaded casing 703. Specifically, the corrugated pipe 704 is arranged at the position between the connection sleeve 801 and the connection ring 201, and can connect the inlet pipe 2 and the drain pipe 3 to the connection sleeve 801.

[0025] As Figure 4 shown, a connection slot 802 is formed on the connection sleeve 801. The inner arcs of the first connecting pipe 4 and the second connecting pipe 5 fit with the inner arc of the connection slot 802. Specifically, when connecting the first connecting pipe 4 and the second connecting pipe 5, they can be inserted into the inside of the connection slot 802.

[0026] As Figure 4 shown, two extrusion limit arc-shaped plates 804 are slidably arranged inside the connection slot 802. The inner arcs of the extrusion limit arc-shaped plates 804 fit with the outer arc surfaces of the first connecting pipe 4 and the second connecting pipe 5.

[0027] As Figure 4As shown, two connecting bolts 803 are threadedly connected to the connecting sleeve 801, and the extrusion limiting arc-shaped plate 804 is connected to the connecting bolt 803; specifically, when the connecting bolt 803 is rotated, the extrusion limiting arc-shaped plate 804 can be driven to slide inside the connecting slot 802, so as to play a role in extruding and limiting the first connecting pipe 4 and the second connecting pipe 5.

[0028] As Figure 3 shown, there is a certain gap between the corrugated pipe 704 and the threaded sleeve 703; specifically, the corrugated pipe 704 has a certain thickness when stacked, so as to avoid hindering the stretching of the corrugated pipe 704. When installing the water pipe pre-filter 1, one hand limits the connecting sleeve 801, and the other hand rotates the threaded sleeve 702, then the corrugated pipe 704 can be driven to stretch or contract, so as to adjust the lengths of the water inlet pipe 2 and the drain pipe 3, which is convenient for installing the water pipe pre-filter 1.

[0029] In summary: When in use, according to the cut length between the first connecting pipe 4 and the second connecting pipe 5, the length adjusting member 7 can be used to adjust the lengths of the water inlet pipe 2 and the drain pipe 3, so as to facilitate inserting the first connecting pipe 4 and the second connecting pipe 5 into the inside of the connecting slot 802. Then, the connecting and limiting member 8 can be used to fix the first connecting pipe 4 and the second connecting pipe 5 inside the connecting slot 802, so as to realize the connection of the pipeline. When adjusting the lengths of the water inlet pipe 2 and the drain pipe 3, under the action of the threaded sleeve 702 and the threaded sleeve 703, the water pipe pre-filter 1 can maintain a straight state, so as to avoid the corrugated pipe 704 being bent to hinder the flow of water.
