Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments.

As used in the utility model specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0035] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0036] In order to solve the technical problem in the prior art that the pipeline connection structure and the pipeline are integrated into one, which increases the difficulty and cost of maintenance; for this purpose, an embodiment of the utility model provides a pipeline connection structure.

[0037] The following is a detailed description of the specific structure of a pipeline connection structure provided by the present utility model embodiment. Figure 1-4 As shown in , the specific structure of the pipeline connection structure includes an outer shell 1, a gland member 2 and a fixing member 3.

[0038] The outer shell 1 is hollow and has an accommodating cavity 11 with openings on both sides; each opening includes a first opening 12 and a second opening 13 for communicating with an external device.

[0039] Specifically, the first opening 12 and the second opening 13 are symmetrically arranged on opposite sides of the outer shell 1, and the first opening 12 and the second opening 13 are both connected to the accommodating chamber 11. The first opening 12 is used to connect the first opening 12 with the accommodating chamber 11 after the pipeline is inserted, and the second opening 13 is used to be assembled at the connecting point of other peripherals. Therefore, when one end of the pipeline is inserted into the first opening 12 of the outer shell 1, at the same time, the connecting point of the peripheral is connected to the second opening 13 of the outer shell 1, thereby realizing mutual circulation between the connecting points of the pipeline and the peripheral, ensuring that the liquid can flow smoothly.

[0040] It is understandable that in the above-mentioned embodiment, the external device connected to the second opening 13 is a pump, a valve, a water tank, a boiler, a cooling device or a pipeline with a larger outer diameter, etc., and the specific connected components or devices are not limited here. For example, the external device is a water tank, and a water supply socket connected to the inside of the water tank is provided on the water tank, and the water supply socket is inserted into the second opening 13, and at the same time, the pipeline is inserted into the first opening 12, so that the water tank and the pipeline are connected to each other.

[0041] according to Figure 1 and Figure 2As shown, the gland member 2 is fixedly inserted into the accommodating cavity 11 , and a communication port 21 is formed in the gland member 2 , which is in communication with the second opening 13 .

[0042] Specifically, in order to ensure that the pipeline inserted into the accommodating cavity 11 can be stable and prevent strong shaking when the internal liquid flows, after the pipeline is inserted into the first opening 12, it continues to extend along the direction of the second opening 13 to the connecting port 21 of the gland 2. Since the outer wall of the pipeline abuts against the inner wall of the connecting port 21, it can prevent the pipeline from shaking strongly when it is connected to the external device and the liquid flows, thereby ensuring the stability of the pipeline when the liquid flows.

[0043] It should be noted that the connecting port 21 of the gland member 2 of the embodiment of the utility model is hollow and has two-side openings, wherein one opening is connected to the second opening 13, and the second opening 13 is connected to the connecting point of the external device, so that when the pipeline extends into the connecting port 21, the liquid can be transported.

[0044] It should also be noted that part of the outer wall of the pressure cover member 2 of the embodiment of the utility model is fixedly abutted against the inner wall of the accommodating cavity 11. It can be understood that the two are fixedly abutted by welding, thereby preventing the pressure cover member 2 from shaking axially in the accommodating cavity 11.

[0045] according to Figure 1 and Figure 2 As shown, the fixing member 3 is clamped at the first opening 12, and the fixing member 3 is hollow to form a clamping opening 31 for clamping the pipeline. The pipeline passes through the clamping opening 31 and then passes through the connecting opening 21, so that the pipeline can be connected with the connecting point of the external device.

[0046] Specifically, the pipeline is passed through the clamping port 31 of the fixing member 3, and then the fixing member 3 is directly inserted into the first opening 12 of the outer shell 1. At this time, the pipeline passes through the fixing member 3 through the clamping port 31 and extends into the connecting port 21 of the gland member 2, so that the pipeline can be connected with the connecting part of the external device. Thus, the fixing member 3 is directly inserted into the first opening 12, thereby achieving the effect of rapid assembly, and the fixing member 3 formed in one piece can be assembled without the use of accessories such as bolts and nuts, thereby saving time and labor costs. In addition, the pipeline is clamped by the fixing member 3 to prevent the pipeline from loosening or falling off during use.

[0047] It should be noted that before the fixing member 3 is inserted into the first opening 12, the pipeline can be passed through the clamping opening 31, that is, the pipeline is clamped and sleeved by the fixing member 3. Subsequently, the fixing member 3 can be inserted into the first opening 12 and clamped in the first opening 12 to prevent the fixing member 3 from loosening or falling off from the first opening 12.

[0048] To sum up the above, the fixing member 3 is clamped on the outer wall of the pipeline. When the fixing member 3 is inserted into the first opening 12 of the outer shell 1, one end of the pipeline is driven to extend into the connecting port 21 of the gland member 2, so that the pipeline is connected to the connecting part of the external device. At this time, liquid can flow. Therefore, the pipeline only needs to be directly inserted into the first opening 12 through the fixing member 3 to be connected to the connecting part of the external device, thereby achieving the effect of rapid assembly without the need for accessories such as bolts and nuts for assembly, and it can also play a pressure-bearing effect.

[0049] according to Figure 3 As shown, in some specific embodiments, the fixing member 3 includes a base body 32 and a plurality of elastic buckle portions 33 disposed on the base body 32 , and the buckle portions 33 surround each other to form a clamping opening 31 .

[0050] Specifically, multiple snap-on portions 33 surround each other in a ring shape to form a clamping opening 31 that can clamp the outer wall of the pipeline; since the snap-on portions 33 have elastic properties, when the pipeline is passed through the clamping opening 31, they can push each snap-on portion 33 to deform, thereby expanding the outer diameter of the clamping opening 31, so that the entire pipeline can be passed through or out of the clamping opening 31, and then, multiple snap-on portions 33 surround the pipeline and clamp it, and the elastic restoring force of the multiple snap-on portions 33 makes it fit tightly to the surface of the pipeline, so as to form a clamping force that can stably clamp the outer wall of the pipeline, thereby preventing the pipeline from loosening or falling out of the accommodating cavity 11. When the fixing member 3 is inserted into the first opening 12, the inner wall of the first opening 12 squeezes the multiple buckle parts 33 at the same time, causing them to deform. Subsequently, when each buckle part 33 is inserted into the inside of the first opening 12, the multiple buckle parts 33 restore their original shapes and are clamped in the first opening 12 to prevent the entire fixing member 3 from falling off outside the first opening 12.

[0051] It should be noted that the side surface of each snap portion 33 facing the clamping opening 31 is a curved surface 331 for fitting against the outer wall of the pipeline; since most pipelines are in the shape of a circular tube, the side surface of each snap portion 33 facing the clamping opening 31 is set as a curved surface 331 that can match the curve of the outer wall of the pipeline, so that when clamping the pipeline, it can fit tightly against the outer wall of the pipeline, thereby providing a uniform clamping force, further ensuring that the pipeline is unlikely to loosen.

[0052] according to Figure 2 As shown, in a further embodiment, an inner flange 121 abutting against the buckle portion 33 is provided on the inner side wall of the first opening 12 .

[0053] Specifically, in order to prevent each buckle portion 33 from falling off after being clamped in the first opening 12, an inner flange 121 is provided through the inner side wall of the first opening 12. When each buckle portion 33 is clamped in the pipeline and passed through the first opening 12, it is blocked by the inner flange 121 in the first opening 12, thereby preventing each buckle portion 33 from falling off from the first opening 12.

[0054] It can be understood that the inner flange 121 of the embodiment of the present invention is in a circular ring shape.

[0055] according to Figure 3 As shown, in a further embodiment, a plurality of buckle portions 33 are distributed along the circumferential direction, and adjacent buckle portions 33 are arranged at intervals.

[0056] Specifically, since the pipeline is in the shape of a circular tube, a plurality of buckle parts 33 are correspondingly arranged in a circumferential distribution to increase the contact area between each buckle part 33 and the pipeline, thereby ensuring that each buckle part 33 can be stably clamped on the outside of the pipeline, and at the same time, each buckle part 33 can achieve uniform force when clamping the pipeline, avoiding local stress concentration. The gaps between the buckle parts 33 can effectively separate the buckle parts 33, so that each buckle part 33 has sufficient space and support, so as to be more stably clamped on the outside of the pipeline.

[0057] according to Figure 2 and Figure 3 As shown, in a further embodiment, a first inclined surface 122 is formed on the side wall of the first opening 12 ; a second inclined surface 332 matching the first inclined surface 122 is formed on each snap portion 33 for guiding each snap portion 33 to be snapped into the first opening 12 .

[0058] Specifically, in order to facilitate each buckle portion 33 to smoothly extend to the first opening 12 and be clamped in the first opening 12, when each buckle is clamped on the outer wall of the pipeline and extends into the first opening 12, the second inclined surface 332 on each buckle portion 33 abuts against the first inclined surface 122, and in the process of pushing the seat body 32 to move axially along the accommodating cavity 11, the second inclined surface 332 can slide on the first inclined surface 122 until each buckle portion 33 is deformed under the squeezing action of the first inclined surface 122, until the first inclined surface 122 and each second inclined surface 332 are misaligned, at which time each buckle portion 33 returns to its original shape and can be clamped in the first opening 12. This arrangement helps to reduce the friction resistance of each buckle portion 33 when extending to the first opening 12, improves the smoothness of the moving process, and does not require a lot of effort to extend each buckle portion 33 into the first opening 12, thereby reducing the difficulty and time consumption during assembly.

[0059] according to Figure 3As shown, in some specific embodiments, a ring-shaped limiting seat 34 is provided at the bottom of the seat body 32 , and the limiting seat 34 abuts against the bottom of the outer shell 1 for assembling the limiting fixing member 3 .

[0060] Specifically, in order to limit the assembly position of the entire fixing member 3 after it is inserted into the first opening 12, when each buckle portion 33 is clamped on the pipeline and the seat body 32 moves axially along the accommodating cavity 11 (the process of the seat body 32 being assembled in the first opening 12), the limiting seat 34 at the bottom of the seat body 32 abuts against the bottom of the outer shell 1 to prevent the entire fixing member 3 from further moving axially in the accommodating cavity 11, that is, precise assembly positioning is achieved through the limiting seat 34.

[0061] It can be understood that the limiting seat 34 of the embodiment of the utility model is in a circular ring shape; or it can be understood that a plurality of protrusions are arranged along the circumference of the bottom of the seat body 32, and the specific type is not limited here.

[0062] according to Figure 1 As shown, in some specific embodiments, a sealing ring 4 for sleeved on the outer wall of the pipeline is provided in the accommodating cavity 11 .

[0063] Specifically, in order to prevent the liquid from leaking to the first opening 12 when the liquid flows after the pipeline is passed through the connecting port 21 of the gland 2, a sealing ring 4 is sleeved on the outer wall of the pipeline and located at the opening of the connecting port 21, thereby preventing the liquid from leaking from the opening of the connecting port 21 to the first opening 12 when flowing, and further improving the sealing of the connection between the pipeline and the external device when the liquid flows.

[0064] It can be understood that the sealing ring 4 in the embodiment of the utility model is made of materials such as rubber, silicone, polyurethane or plastic, and the specific manufacturing material is not limited here.

[0065] according to Figure 2 As shown, in some specific embodiments, the accommodating cavity 11 includes a first cavity 111 and a second cavity 112 communicating with the first cavity 111 , the first opening 12 communicating with the first cavity 111 , and the second opening 13 communicating with the second cavity 112 .

[0066] Specifically, the accommodating cavity 11 is divided into a first cavity 111 and a second cavity 112, wherein the cavity diameter of the first cavity 111 is smaller than that of the second cavity 112, and thus, the first cavity 111 with a smaller cavity diameter is used for the passage of pipelines, and the second cavity 112 with a larger cavity diameter is used for assembly at the connection point of an external device or a pipeline with a larger outer diameter; since the first cavity 111 is connected to the second cavity 112, when the pipeline is simultaneously passed through the first cavity 111 and the connecting port 21 of the gland 2, at the same time, the outer shell 1 is assembled at the connection point of an external device or a pipeline with a larger outer diameter through the second cavity 112, so that the pipeline can be connected to the connection point of the external device or the pipeline with a larger outer diameter.

[0067] according to Figure 4 As shown, in a further embodiment, the top of the gland member 2 is provided with an outer flange 22 abutting against the bottom wall of the second cavity 112 to prevent the gland member 2 from moving along the first opening 12 .

[0068] Specifically, in order to improve the stability of the gland member 2 and prevent the gland member 2 from shaking in the axial direction when the liquid flows, an outer flange 22 is set on the top of the gland member 2. Since the outer diameter of the outer flange 22 is larger than the width of the first cavity 111, the outer flange 22 abuts against the bottom cavity wall of the second cavity 112. The bottom cavity wall is used to block the outer flange 22, thereby preventing the entire gland member 2 from shaking in the axial direction, thereby further improving the stability of the gland member 2.

[0069] It can be understood that the outer flange 22 of the embodiment of the present invention has a circular ring shape.

[0070] according to Figure 4 As shown, in some specific embodiments, a stepped end 211 is provided on the inner side of the communication port 21 to abut against the protrusion on the outer side of the pipeline.

[0071] Specifically, when the pipeline is passed through the connecting port 21, in order to prevent the pipeline from passing through the second cavity 112, the stepped end 211 on the side wall of the connecting port 21 abuts against the protrusion of the pipeline, so that the pipeline is blocked at this position to prevent the pipeline from moving further.

[0072] It can be understood that the stage end of the embodiment of the utility model is an inner protrusion provided on the inner side wall of the communication port 21 .

[0073] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
