[0031] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0032] First, see Figure 1 and Figure 2 , is a connection structure 10 provided in an embodiment of the present application. The connection structure 10 can be used to quickly install a water pressure gauge on a pipeline. The connection structure 10 can include a female connector 1, a male connector 2 and a locking member 3. The male connector 2 can be plugged into the female connector 1.

[0033] The female connector 1 can be set with both ends through, that is, the inside of the female connector 1 has a first channel, the first channel connects the opposite ends of the female connector 1 to each other, and the female connector 1 has a female docking end 11, the side wall of the female docking end 11 can be provided with an assembly port 111, the assembly port 111 can pass through the inner and outer side surfaces of the female docking end 11, or it can be said that the assembly port 111 is connected to the first channel inside the female connector 1.

[0034] The male connector 2 can also be set with both ends through, that is, the inside of the male connector 2 has a second channel, the second channel connects the opposite ends of the male connector 2 to each other, and the male connector 2 has a male docking end 21, the side wall of the male docking end 21 can be provided with a first groove 211, the notch of the first groove 211 is set in a direction away from the second channel, the outer diameter length of the male docking end 21 is adapted to the inner diameter length of the female docking end 11, so that the male docking end 21 can be inserted into the inside of the female docking end 11, and the first groove 211 is arranged opposite to the assembly port 111, and the first groove 211 can be connected to the assembly port 111.

[0035] The shape of the locking piece 3 can be adapted to the notches of the assembly opening 111 and the first groove 211, so that the locking piece 3 can be inserted into the assembly opening 111 and the first groove 211 in sequence, and the locking piece 3 can be in a locked state with the assembly opening 111 and the first groove 211 at the same time, thereby fixing the female connector 1 and the male connector 2.

[0036] When the water pressure gauge needs to be installed on the pipeline, the end of the male connector 2 facing away from the male docking end 21 can be connected to the water pressure gauge and conducted, and the end of the female connector 1 facing away from the female docking end 11 can be connected to the pipeline and conducted, and the male docking end 21 can be inserted into the inside of the female docking end 11 so that the first groove 211 and the assembly port 111 are arranged relative to and communicated with. At this time, it is only necessary to insert the locking piece 3 into the assembly port 111 and the first groove 211 in turn, and the female docking end 11 and the male docking end 21 can be fixed, so that the female connector 1 and the male connector 2 are fixed, thereby fixing the water pressure gauge on the pipeline. The staff does not need to use a lot of force, and the installation is very convenient. When the water pressure gauge needs to be repaired or replaced, it is only necessary to pull out the locking piece 3 from the assembly port 111 and the first groove 211 to release the fixation of the female connector 1 and the male connector 2, and the water pressure gauge body 20 can be easily removed from the pipeline.

[0037] See also Figures 1 to 3 In some embodiments, a positioning boss 212 can be provided on the peripheral side surface of the male docking end 21, a positioning groove 112 can be provided on the end surface of the female docking end 11, and the positioning groove 112 can pass through the inner side surface of the female docking end 11, so that the positioning boss 212 can be inserted into the positioning groove 112.

[0038] Optionally, the positioning boss 212 can protrude outward from the peripheral side surface of the male docking end 21, and the end face of the female docking end 11 can be provided with a positioning groove 112 that is compatible with the positioning boss 212. Before the male docking end 21 is inserted into the female docking end 11, the positioning boss 212 can be aligned with the positioning groove 112, so that after the male docking end 21 is inserted into the female docking end 11, the positioning boss 212 can be inserted into the positioning groove 112. The positioning boss 212 and the positioning groove 112 are plugged into each other, which can limit the relative rotation between the male docking end 21 and the female docking end 11, so that the male docking end 21 and the female docking end 11 can be fixed more stably.

[0039] In some other embodiments, when the male docking end 21 is plugged into the female docking end 11, the axis of the male docking end 21 can be set collinearly with the axis of the female docking end 11, and as the male docking end 21 is gradually inserted into the interior of the female docking end 11, the positioning boss 212 can contact the bottom surface of the positioning groove 112. At this time, the positioning groove 112 can limit the male docking end 21 from continuing to be inserted into the female docking end 11 along its own axial direction. It can also be said that after the male docking end 21 is inserted into the female docking end 11 to a preset depth, the male docking end 21 cannot continue to extend into the female docking end 11, and the first groove 211 and the assembly opening 111 are just set opposite to each other.

[0040] Therefore, by plugging and fitting the positioning boss 212 with the positioning groove 112, the male docking end 21 can be quickly inserted into the preset position in the female docking end 11, so that the first groove 211 is arranged relative to and connected to the assembly port 111, which can increase the assembly speed and accuracy of the male connector 2 and the female connector 1.

[0041] See also Figure 3 In some embodiments, the positioning groove 112 can pass through the inner and outer side surfaces of the female docking end 11 , so that the positioning groove 112 can be exposed on the outer side surface of the female docking end 11 .

[0042] Optionally, when the male docking end 21 is inserted into the female docking end 11, the position of the positioning groove 112 can be intuitively seen from the outside of the female docking end 11, and the positioning boss 212 on the male docking end 21 can be easily aligned with the positioning groove 112, so that the male docking end 21 can be easily inserted into the female docking end 11.

[0043] See also Figure 2 In some embodiments, the connection structure 10 can further include a sealing ring 4 , which can be disposed between the female butt end 11 and the male butt end 21 to seal the gap between the female butt end 11 and the male butt end 21 .

When the male docking end 21 is inserted into the female docking end 11, the sealing ring 4 can seal the gap between the female docking end 11 and the male docking end 21 to prevent fluid leakage from the gap, and can also prevent the fluid from flowing to the assembly port 111 and the first groove 211.

[0045] See also Figure 2 and 4 In some embodiments, a second groove 213 can be provided on the peripheral side surface of the male butt end 21, and the second groove 213 can be spaced apart from the first groove 211 along the axial direction of the male connector 2, and along the axial direction of the male connector 2, the second groove 213 is located on the side of the first groove 211 close to the end face of the male butt end 21, and the sealing ring 4 can be arranged in the second groove 213.

[0046] Optionally, two grooves can be provided on the circumferential side surface of the male butt end 21, and the two grooves are arranged at intervals along the axial direction of the male butt end 21. The groove closer to the end face of the male butt end 21 of the two grooves is the second groove 213, and the groove farther away from the end face of the male butt end 21 of the two annular grooves is the first groove 211. The sealing ring 4 is arranged in the second groove 213, which can not only seal the gap between the female butt end 11 and the male butt end 21, but also isolate the first groove 211 from the first channel in the female butt end 11, thereby preventing the fluid in the female butt end 11 from flowing to the first groove 211.

[0047] Optionally, by setting a second groove 213, a position for installing the sealing ring 4 can be formed, so that the sealing ring 4 can be fixed on the peripheral side surface of the male docking end 21, and the second groove 213 can also play a limiting role on the sealing ring 4. During the process of inserting the male docking end 21 into the female docking end 11, the sealing ring 4 can be prevented from moving along the axial direction of the male docking end 21.

[0048] Optionally, the groove depth of the second groove 213 is smaller than the thickness of the sealing ring 4. When the sealing ring 4 is arranged in the second groove 213, the sealing ring 4 at least partially extends from the second groove 213, so that the sealing ring 4 can be squeezed between the male docking end 21 and the female docking end 11, thereby increasing the sealing between the male docking end 21 and the female docking end 11.

[0049] See also Figures 1 to 3 In some embodiments, the side wall of the female docking end 11 can be provided with two assembly openings 111, and the two assembly openings 111 are located on opposite sides of the axial direction of the female connector 1.

[0051] When the two locking arms 31 are respectively inserted into the two assembly openings 111, both locking arms 31 can be inserted into the first groove 211, and the two locking arms 31 can also clamp the male docking end 21 so that the male docking end 21 is clamped in the clamping space 311. The male docking end 21 and the female docking end 11 can be fixed together through the two locking arms 31, and the opposite sides of the male docking end 21 are subjected to force, so that the fixation can be more stably.

[0052] See also Figure 2 In some embodiments, an avoidance groove 312 can be provided between the two locking arms 31 . The avoidance groove 312 can be communicated with the clamping space 311 , and the avoidance groove 312 can allow the wall between the two assembly openings 111 to be inserted.

[0053] Optionally, when the two locking arms 31 are respectively inserted into the two assembly openings 111, the wall between the two assembly openings 111 can be inserted into the avoidance groove 312, which can prevent the locking member from interfering with the female docking end 11, so that the locking arm 31 can be inserted into the assembly opening 111, and the locking arm 31 can also be inserted into the first groove 211.

[0054] Optionally, when the male connector 2 and the female connector 1 are placed separately, the locking piece 3 can also be inserted into the two assembly openings 111, so that the locking piece 3 is assembled on the female connector 1. The locking piece 3 and the female connector 1 can be placed together, which is convenient for taking the locking piece 3 when subsequently assembling the male connector 2 and the female connector 1.

[0055] See also Figure 2 In some embodiments, the portion of the locking member 3 inserted into the first groove 211 has an arc surface 313 , and the arc surface 313 can be adapted to the bottom surface of the first groove 211 .

[0056] Optionally, the locking member 3 includes two locking arms 31 connected to each other, and the sides of the two locking arms 31 close to each other have arc surfaces 313 respectively. When the locking arms 31 are inserted into the first groove 211, the arc surfaces 313 can fit with the bottom surface of the first groove 211, so that the two locking arms 31 can clamp the male docking end 21 more tightly, and the locking member 3 can more stably fix the female docking end 11 and the male docking end 21 together.
