[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] In addition, the utility model may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplicity and clarity, and does not indicate the relationship between the various embodiments and / or settings discussed. In addition, the utility model provides various specific examples of processes and materials, but those skilled in the art can recognize the application of other processes and / or the use of other materials.

[0032] In the related art, the pipe has a mounting end and a free end. The free end is suitable for drainage and sewage. During installation, the mounting end of the pipe needs to be connected to the mounting hole of the equipment to achieve the drainage and sewage functions of the pipe. However, in actual use, users often mistakenly connect the free end to the mounting hole of the equipment as the mounting end, resulting in installation failure and affecting the installation progress; or, after the user mistakenly installs the free end in the mounting hole of the equipment, he mistakenly thinks that the installation is successful. Since the free end does not match the mounting hole, sewage and the like flow into the interior of the equipment, causing unnecessary losses.

[0033] The present invention is described below with reference to the accompanying drawings and specific embodiments:

[0034] The first embodiment of the utility model provides a foolproof pipeline. Figures 1 to 3 , including a tube body 100 and a blocking member 200, the tube body 100 has a mounting end 110 and a free end 120; the blocking member 200 is arranged at the free end 120, and the blocking member 200 is suitable for preventing confusion between the free end 120 and the mounting end during installation.

[0035] The fixing of the fool-proof pipe is achieved by cooperating between the mounting end 110 and the mounting hole 430 of the equipment; by setting a blocking member 200 at the free end 120 of the pipe body 100, the size of the blocking member 200 is larger than the aperture of the mounting hole 430, so that the free end 120 cannot enter the mounting hole 430 of the equipment, so that the user can detect the installation error in time, thereby preventing the user from mistakenly installing the free end 120 into the mounting hole 430, thereby achieving a fool-proof effect; in addition, the blocking member 200 plays a certain identification role, and the user can identify the mounting end 110 and the free end 120 through the blocking member 200 before installation, so as to avoid mistakenly installing the free end 120, resulting in installation failure, and reducing the risk of damage to the equipment or pipeline.

[0036] Generally, the foolproof pipe has a free end 120 and a mounting end 110. Of course, in other embodiments, multiple free ends 120 or multiple mounting ends 110 may be provided to meet different usage requirements, which is not particularly limited in the embodiments of the present invention. The blocking member 200 may be provided on the side wall of the free end 120 or on the end surface of the free end 120. The present invention does not particularly limit the specific position of the blocking member 200 on the free end 120.

[0037] The tube body 100 is suitable for passage of fluids such as liquid or gas, and the tube body 100 can be a straight tube or a curved tube.

[0038] In some embodiments, the blocking member 200 is arranged on the inner side of the free end 120. Due to the function of the blocking member 200, the mounting hole 430 of the device cannot accommodate the free end 120, so as to prevent installation errors. By using the space on the inner side of the free end 120 to arrange the blocking member 200, it is possible to avoid increasing the overall size of the foolproof pipe and effectively utilize the internal space of the pipe body 100. While preventing installation errors, the outer surfaces of the free end 120 and the mounting end 110 can be kept consistent, which is conducive to uniform processing of the outer surface of the foolproof pipe. It should be noted that along the axial direction of the pipe body 100, the cross-sectional area of ​​the blocking member 200 located on the inner side of the pipe body 100 is smaller than the cross-sectional area of ​​the internal channel of the pipe body 100, so as to prevent the blocking member 200 from interfering with the normal operation of the pipe body 100. Preferably, the blocking member 200 can be one or more protrusions protruding radially inward to prevent it from being sleeved on the connecting pipe 410.

[0039] In some embodiments, see Figure 1, the blocking member 200 is arranged on the outside of the free end 120. Due to the function of the blocking member 200, the installation hole 430 of the device cannot accommodate the free end 120, so as to prevent installation errors; the blocking member 200 is arranged on the outside of the free end 120, making the blocking member 200 more conspicuous, so that the user can quickly identify the free end 120, reduce the risk of installation errors, and improve the installation speed. The blocking member 200 is located on the outside of the free end 120, which can reduce the influence of the blocking member 200 on the inside of the tube body 100, so that the fluid inside the tube body 100 can flow smoothly and avoid blockage inside the tube body 100. In addition, the blocking member 200 is arranged on the outside of the free end 120, which facilitates the processing of the blocking member 200 and reduces the processing cost of the foolproof pipe.

[0040] In some embodiments, two blocking members 200 may be provided, wherein one blocking member 200 is provided on the outside of the free end 120, and the other blocking member 200 is provided on the inside of the free end 120. The blocking member 200 located on the inside of the free end 120 and the blocking member 200 located on the outside of the free end 120 may act simultaneously to prevent the installation of the free end 120; the two blocking members 200 serve as backup, and if one of the blocking members 200 is damaged, the other blocking member 200 may continue to function, thereby improving the reliability of the foolproof pipe. In other embodiments, only one blocking member 200 may be provided, and the blocking member 200 may protrude from the side wall of the pipe body 100 to the outside and inside of the free end 120, so as to increase the structural strength of the blocking member 200 and prevent the blocking member 200 from breaking when preventing the installation of the free end 120.

[0041] In some embodiments, see Figure 1 The blocking member 200 extends along the radial direction of the tube body 100 , so that when the free end 120 enters the mounting hole 430 , the blocking member 200 can prevent the free end 120 from fitting into the mounting hole 430 in time.

[0042] In some embodiments, at least a portion of the blocking member 200 protrudes from the end surface of the free end 120, making the free end 120 more recognizable. The user can quickly identify and distinguish the free end 120 and the mounting end 110 through the portion of the blocking member 200 protruding from the end surface, thereby reducing installation errors. Of course, in other embodiments, the blocking member 200 may also protrude entirely from the end surface of the free end 120, and the present invention does not specifically limit this.

[0043] In some embodiments, see Figure 1, the outer diameter of the blocking member 200 is larger than the outer diameter of the mounting end 110. Since the mounting end 110 matches the mounting hole 430, and the outer diameter of the blocking member 200 is larger than the outer diameter of the mounting end 110, the free end 120 cannot be inserted into the mounting hole 430. When the user tries to insert the free end 120 into the mounting hole 430, the user can quickly find that the free end 120 does not match the mounting hole 430 due to the setting of the blocking member 200, and stop the wrong installation in time. The outer diameter of the blocking member 200 is the maximum distance from the blocking member 200 to the axis of the tube body 100. The outer diameter of the blocking member 200 is larger than the outer diameter of the mounting end 110, that is, the maximum distance from any point on the blocking member 200 to the axis of the tube body 100 is larger than the outer diameter of the mounting end 110, so as to achieve the obstruction of the installation of the free end 120.

[0044] Generally, during the installation of the tube body 100, the mounting end 110 of the tube body 100 is inserted into the mounting hole 430 of the device and connected to the connecting tube 410 in the mounting hole 430. The outer diameter of the mounting end 110 needs to match the aperture of the mounting hole 430, and the inner diameter of the mounting end 110 needs to match the outer diameter of the connecting tube 410, so that the mounting end 110 of the tube body 100 cooperates with the connecting tube 410.

[0045] In some embodiments, the inner diameter of the blocking member 200 is smaller than the inner diameter of the mounting end 110. Since the mounting end 110 cooperates with the connecting tube 410 in the mounting hole 430, and the inner diameter of the blocking member 200 is smaller than the inner diameter of the mounting end 110, the free end 120 cannot be inserted into the mounting hole 430 due to the obstruction of the blocking member 200. When the user tries to insert the free end 120 into the mounting hole 430, the user can quickly find that the free end 120 does not match the connecting tube 410 due to the setting of the blocking member 200, and stop the wrong installation in time. The inner diameter of the blocking member 200 is the minimum distance from the blocking member 200 to the axis of the tube body 100. The inner diameter of the blocking member 200 is smaller than the inner diameter of the mounting end 110, that is, the minimum distance from any point on the blocking member 200 to the axis of the tube body 100 is smaller than the inner diameter of the mounting end 110, so as to achieve the obstruction of the installation of the free end 120.

[0046] In some embodiments, the outer diameter of the blocking member 200 is larger than the outer diameter of the mounting end 110, and the inner diameter of the blocking member 200 is smaller than the inner diameter of the mounting end 110. While achieving a foolproof effect, the size of the blocking member 200 in the radial direction of the tube body 100 can be increased, thereby increasing the structural strength of the blocking member 200 and preventing the blocking member 200 from breaking. In other embodiments, the structural strength of the blocking member 200 can be increased by increasing the size of the blocking member 200 in the axial direction of the tube body 100.

[0047] In some embodiments, see Figures 4 to 6The outer contour of the cross section of the blocking member 200 includes a circular, triangular, rectangular or polygonal shape. The circular outer contour shape facilitates the processing of the blocking member 200, and the triangular, rectangular or polygonal outer contour shape can increase the recognition of the free end 120, so that the user can quickly distinguish the free end 120 and the installation end 110 of the foolproof pipe; the blocking member 200 can also be a prismatic configuration (such as Figure 7 The free end 120 is a triangular prism or a multi-prism as shown in the figure, which constitutes part or all of the free end 120. Of course, the outer contour of the cross section of the blocking member 200 can be set according to actual needs, and the embodiment of the utility model is not particularly limited to this. The cross section of the blocking member 200 is the cross section of the blocking member 200 in the axial direction of the tube body 100. Generally, the inner contour of the cross section of the blocking member 200 is the same as the inner contour of the cross section of the tube body 100, so that the fluid inside the tube body 100 can flow through.

[0048] In some embodiments, see Figure 1 The blocking member 200 includes at least one protrusion 210, which is distributed around the free end 120, and the outer edge of the protrusion exceeds the mounting hole 430. Multiple protrusions 210 can be provided, and the provision of multiple protrusions 210 can better play the role of hindering the installation of the free end 120. Secondly, compared with the annular shape, the provision of multiple protrusions 210 can save more materials of the blocking member 200 while playing a fool-proof effect; the protrusion 210 can face the inside of the tube body 100, or the outside of the tube body 100, and the embodiment of the utility model does not specifically limit this.

[0049] The second embodiment of the utility model provides a pipe joint, see Figure 4 , including a joint and a blocking member 200 , the joint is suitable for connecting the pipe body 100 , the blocking member 200 is arranged on the joint and is suitable for hindering the installation of the pipe body 100 .

[0050] Due to the blocking effect of the blocking member 200, the end of the tube body 100 provided with the blocking member 200 cannot enter the installation hole 430 of the device, so that the user can promptly detect the installation error, which has a foolproof effect. Generally, the joint is connected to the free end 120 of the tube body 100 to block the installation of the free end 120 of the tube body 100.

[0051] The third embodiment of the utility model is an electrical device, see Figure 2 , including a housing 400 and a fool-proof pipe or a pipe joint, the housing 400 is provided with a mounting hole 430, and the pipe body 100 is connected to the mounting hole 430.

[0052] It can be understood that if the fool-proof pipes and pipe joints have the beneficial effects of the above embodiments, then the electrical equipment will correspondingly have the beneficial effects of the above embodiments.

[0054] In some embodiments, see Figures 2 to 3 A first matching portion 111 is disposed on the peripheral side of the mounting end 110 of the tube body 100 , and a second matching portion 420 is disposed inside the mounting hole 430 , and the first matching portion 111 matches with the second matching portion 420 .

[0055] Through the cooperation of the first matching part 111 and the second matching part 420, the sealing can be improved, and at the same time, the connection between the mounting end 110 and the mounting hole 430 can be strengthened to reduce the risk of the tube body 100 falling off. One of the first matching part 111 and the second matching part 420 is a connecting protrusion 210, and the other is a connecting groove. The reliability of the fool-proof pipe connection is improved by the connecting protrusion 210 and the connecting groove. The connecting protrusion 210 can be arranged on the mounting end 110 of the tube body 100, and the connecting groove is arranged on the outer shell to improve the structural strength of the tube body 100. The shape of the connecting protrusion 210 and the connecting groove can be designed according to the contact surface between the mounting end 110 and the outer shell. Of course, the first matching part 111 and the second matching part 420 can also be matching steps or other complex structures, and the embodiment of the utility model does not impose any special restrictions on this.
