[0003] However, the threaded sleeve or the sleeve, etc. may cause the relative positions of the threaded sleeve or the sleeve to be inconsistent due to the inconsistent tightening force, which may reduce the locking effect of the two pipe fittings, and further result in low locking reliability of the two pipe fittings. Summary of the Utility Model

[0029] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the specific implementation manners of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application.

[0031] As used in the specification and appended claims of this application, the singular forms "a", "the", and "said" are also intended to include the plural forms, unless the context clearly dictates otherwise. It should also be understood that the term "and / or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

[0032] As Figure 1 and Figure 2 As shown, this application provides a connecting pipe assembly 100, which includes a first pipe fitting 11, a second pipe fitting 12, and a locking mechanism 13. Among them, the first pipe fitting 11 and the second pipe fitting 12 are rotatably connected so that the first pipe fitting 11 and the second pipe fitting 12 can rotate relative to each other. The locking mechanism 13 is used to lock the relative positions between the first pipe fitting 11 and the second pipe fitting 12. In this application, both the first pipe fitting 11 and the second pipe fitting 12 are round pipes.

[0033] Specifically, the second pipe fitting 12 rotates relative to the first pipe fitting 11 so that the second pipe fitting 12 has a deployed state and a folded state. When the second pipe fitting 12 is in the deployed state, the axis of the second pipe fitting 12 and the axis of the first pipe fitting 11 are on the same straight line; when the second pipe fitting 12 is in the folded state, the axis of the second pipe fitting 12 is not parallel to the axis of the first pipe fitting 11. More specifically, when the second pipe fitting 12 is in the deployed state, the locking mechanism 13 can lock the relative positions between the first pipe fitting 11 and the second pipe fitting 12 so that the axis of the second pipe fitting 12 and the axis of the first pipe fitting 11 are always on the same straight line, thereby enabling the second pipe fitting 12 to always be in the deployed state. Through the above arrangement, when the first pipe fitting 11 and the second pipe fitting 12 are in the working state, that is, when the second pipe fitting 12 is in the deployed state, the locking mechanism 13 enables the first pipe fitting 11 and the second pipe fitting 12 to remain relatively fixed, thereby improving the working stability of the first pipe fitting 11 and the second pipe fitting 12.

[0034] As Figure 3As shown in the figure, in this embodiment, the first pipe fitting 11 is provided with a rotating groove 111, and at least a part of the second pipe fitting 12 can be located in the rotating groove 111, so that at least a part of the first pipe fitting 11 can be sleeved on the second pipe fitting 12. Among them, the second pipe fitting 12 has a rotating section 121, and the rotating section 121 is rotatably connected to the first pipe fitting 11 and at least partially located in the rotating groove 111, so that the rotating section 121 can rotate relative to the first pipe fitting 11 through the rotating groove 111, thereby enabling the second pipe fitting 12 to have an unfolded state and a folded state. Specifically, when the second pipe fitting 12 is in the unfolded state, the locking mechanism 13 can cover the rotating groove 111 and be fixed to the first pipe fitting 11, so as to limit the rotating section 121 in the rotating groove 111 through the locking mechanism 13, and further prevent the rotating section 121 from rotating relative to the first pipe fitting 11, so as to realize the locking function of the locking mechanism 13 on the rotating section 121, which is beneficial to the first pipe fitting 11 and the second pipe fitting 12 to maintain relative fixation. When the second pipe fitting 12 is in the folded state, the locking mechanism 13 does not cover the rotating groove 111, so that the rotating section 121 can rotate relative to the first pipe fitting 11. At this time, the rotating section 121 can rotate so that at least a part of the rotating section 121 is located outside the rotating groove 111, so that the axis of the second pipe fitting 12 is not parallel to the axis of the first pipe fitting 11, which is beneficial to the folding of the second pipe fitting 12 relative to the first pipe fitting 11, and further can reduce the space occupied by the first pipe fitting 11 and the second pipe fitting 12, so as to realize the storage of the second pipe fitting 12.

[0035] As Figure 3 and Figure 4 shown, as an implementation manner, the locking mechanism 13 includes a locking body 131, a first locking member 132 and a second locking member 133. One end of the locking body 131 is rotatably connected to the first pipe fitting 11, and a connecting portion 1311 is provided at the other end of the locking body 131. Both the first locking member 132 and the second locking member 133 are rotatably connected to the connecting portion 1311. Specifically, the locking body 131 extends substantially along a preset curve direction, and the two ends of the locking body 131 extending along the preset curve direction are defined as a connecting end 1312 and a locking end 1313. The connecting end 1312 is rotatably connected to the first pipe fitting 11, so that the locking body 131 can be located on the first pipe fitting 11, thereby avoiding the loss of the locking body 131 when the locking mechanism 13 does not lock the first pipe fitting 11 and the second pipe fitting 12. The connecting portion 1311 is provided on the locking end 1313, so that the first locking member 132 and the second locking member 133 are rotatably connected to the locking end 1313.

[0036] Wherein, the first locking member 132 and the second locking member 133 are rotationally connected to the locking body 131 through the same rotating shaft 134, that is, the first locking member 132 and the second locking member 133 can be rotationally connected to the locking end 1313 through the same rotating shaft 134, so that the first locking member 132 and the second locking member 133 can be connected to the locking body 131 simultaneously, thereby facilitating the assembly of the first locking member 132 and the second locking member 133; at the same time, the above setting can prevent the positions of the first locking member 132 and the second locking member 133 on the locking body 131 from shifting due to assembly errors, thereby improving the working stability of the first locking member 132 and the second locking member 133.

[0037] Exemplarily, the connecting portion 1311 can be two sheet-like structures extending from the locking end 1313 away from the connecting end 1312. Connecting holes are provided on both sheet-like structures. A rotating shaft 134 passes through the connecting holes on the two sheet-like structures, the first locking member 132, and the second locking member 133, so that the first locking member 132 and the second locking member 133 can rotate relative to the connecting portion 1311.

[0038] It should be noted that the rotating shaft 134 can be a pin shaft. After the pin shaft passes through the connecting holes on the two sheet-like structures, the first locking member 132, and the second locking member 133, it is clamped with a snap ring, so that the pin shaft will not fall off the rotating portion. The rotating shaft 134 can also be a bolt. After the bolt passes through the connecting holes on the two sheet-like structures, the first locking member 132, and the second locking member 133, it is fixed with a nut. The present application does not make any restrictions.

[0039] When the second pipe fitting 12 is in the unfolded state, the locking body 131 can at least partially cover the rotating groove 111. The first locking member 132 rotates relative to the connecting portion 1311 and is clamped with the first pipe fitting 11, and the second locking member 133 rotates relative to the connecting portion 1311 and is clamped with the first pipe fitting 11. Through the above setting, a double connection of the first locking member 132 - the first pipe fitting 11 and the second locking member 133 - the first pipe fitting 11 can be formed between the locking mechanism 13 and the first pipe fitting 11, so that the connection between the locking mechanism 13 and the first pipe fitting 11 is more stable. Furthermore, the locking body 131 can cover the rotating groove 111 more stably. Then, when the second pipe fitting 12 is in the unfolded state, the rotating section 121 is restricted in the rotating groove 111 by the locking body 131, and the locking body 131 is fixed to the first pipe fitting 11 by the first locking member 132 and the second locking member 133, so that the rotating section 121 cannot rotate relative to the first pipe fitting 11, which is beneficial for the first pipe fitting 11 and the second pipe fitting 12 to remain relatively fixed.

[0040] Such as Figure 4 and Figure 5As shown, as an implementation, the first locking member 132 includes an abutting portion 1321, a first clamping portion 1322, and a first rotating portion 1323. The first clamping portion 1322 can be clamped with the first pipe fitting 11. The first rotating portion 1323 is located between the first clamping portion 1322 and the abutting portion 1321, and the first rotating portion 1323 is rotatably connected to the connecting portion 1311. That is, when the first locking member 132 is rotatably connected to the locking body 131, the abutting portion 1321 and the first clamping portion 1322 are distributed on both sides of the connecting portion 1311 along the extending direction of the locking body 131. Among them, the abutting portion 1321, the first clamping portion 1322, and the first rotating portion 1323 are integrally formed or fixedly connected.

[0041] Specifically, the locking body 131 is provided with a limiting rod 1314 for restricting the rotation angle of the first clamping portion 1322. The limiting rod 1314 is located at one end of the locking body 131 where the connecting portion 1311 is provided. More specifically, the limiting rod 1314 is located between two sheet-like structures extending from the locking end 1313 away from the connecting end 1312, and both ends of the limiting rod 1314 are respectively connected to the above two sheet-like structures. Through the above settings, when the first locking member 132 rotates with the connecting portion 1311, the first clamping portion 1322 can only rotate to the position where it abuts against the limiting rod 1314 and cannot continue to rotate, so that the rotation angle of the first clamping portion 1322 can be limited by the limiting rod 1314.

[0042] Specifically, the abutting portion 1321 abuts against the locking body 131 through an elastic member 135. When the first clamping portion 1322 abuts against the limiting rod 1314, the elastic member 135 has a pre-tightening force acting on the abutting portion 1321. The above pre-tightening force causes the abutting portion 1321 to have a tendency to move away from the locking body 131, so that the first clamping portion 1322 has a tendency to move towards the limiting rod 1314. Through the above settings, through the cooperation between the limiting rod 1314 and the elastic member 135, the pre-tightening force of the elastic member 135 on the abutting portion 1321 will not cause the rotation angle of the first clamping portion 1322 to be too large, thereby avoiding the rotation angle of the first clamping portion 1322 being too large and causing the elastic member 135 to fall off between the abutting portion 1321 and the locking body 131. At the same time, when the first clamping portion 1322 is clamped with the first pipe fitting 11, only an acting force towards the locking body 131 needs to be applied to the abutting portion 1321 so that the abutting portion 1321 can overcome the pre-tightening force of the elastic member 135 and move towards the locking body 131, so that the first clamping portion 1322 can be disengaged from the first pipe fitting 11. When the acting force applied to the abutting portion 1321 is removed, the pre-tightening force of the elastic member 135 on the abutting portion 1321 causes the first clamping portion 1322 to abut against the limiting rod 1314, facilitating the next clamping of the first clamping portion 1322 and the first pipe fitting 11.

[0043] In this embodiment, a limiting portion 1321a is formed at one end of the abutting portion 1321 away from the first rotating portion 1323. The limiting portion 1321a faces the locking body 131, and the limiting portion 1321a can be used to limit the rotation angle of the abutting portion 1321. When the first engaging portion 1322 is engaged with the first pipe fitting 11, the first engaging portion 1322 abuts against the limiting rod 1314, or the first engaging portion 1322 is arranged close to the limiting rod 1314. When the abutting portion 1321 receives a force towards the locking body 131 to compress the elastic member 135, the first engaging portion 1322 is separated from the first pipe fitting 11, and the limiting portion 1321a can limit the rotation angle of the abutting portion 1321, thereby limiting the rotation angle of the first engaging portion 1322. Through the above arrangement, the rotation angle of the first locking member 132 relative to the connecting portion 1311 can be limited by the cooperation between the limiting rod 1314, the elastic member 135 and the limiting portion 1321a, thereby avoiding the detachment of the elastic member 135 due to the excessive distance between the abutting portion 1321 and the locking body 131, and avoiding the damage of the elastic member 135 due to the too small distance between the abutting portion 1321 and the locking body 131.

[0044] Optionally, the elastic member 135 can be set as a spring. The locking body 131 is formed with a first convex portion 1315, and the first convex portion 1315 is arranged close to the connecting portion 1311. Specifically, the first convex portion 1315 is located on the side of the connecting portion 1311 away from the limiting rod 1314. The abutting portion 1321 is formed with a second convex portion 1321b, and the second convex portion 1321b is located on the side of the abutting portion 1321 close to the locking body 131. One end of the spring is sleeved on the first convex portion 1315, and the other end of the spring is sleeved on the second convex portion 1321b, so that the first convex portion 1315 and the second convex portion 1321b can limit the position of the spring, making the work of the spring more stable.

[0045] It should be noted that the elastic member 135 can also be other elastic components. For example, the elastic member 135 can also be rubber, etc. The present application does not make any restrictions, as long as the elastic member 135 can have a pre-tightening force acting on the abutting portion 1321.

[0046] As an implementation manner, the second locking member 133 includes a second rotating portion 1331 and a second engaging portion 1332, and the second rotating portion 1331 is rotatably connected to the connecting portion 1311. Among them, the second rotating portion 1331 and the first rotating portion 1323 are connected by the same rotating shaft 134 (refer to Figure 3)It is rotationally connected to the connecting portion 1311. When at least a part of the locking body 131 covers the rotating groove 111, the second clamping portion 1332 can be clamped with the first pipe fitting 11, so that the second clamping portion 1332 and the first clamping portion 1322 are simultaneously clamped with the first pipe fitting 11, thereby improving the locking effect of the locking mechanism 13 on the first pipe fitting 11 and the second pipe fitting 12, which is beneficial to improving the working stability of the first pipe fitting 11 and the second pipe fitting 12.

[0047] In this embodiment, the second clamping portion 1332 is disposed at least partially around the first clamping portion 1322. Specifically, the second clamping portion 1332 extends at least along a "U" shape, so that at least a part of the second clamping portion 1332 forms a receiving space, and the first clamping portion 1322 is located in the receiving space, thereby reducing the space occupancy rate of the first clamping portion 1322 and the second clamping portion 1332, and further improving the structural compactness of the first clamping portion 1322 and the second clamping portion 1332. At the same time, the above setting also makes the distance between the first clamping portion 1322 and the second clamping portion 1332 closer, which is beneficial to the operation of the first locking member 132 and the second locking member 133, so as to improve the operation convenience of the first clamping portion 1322 and the second clamping portion 1332.

[0048] More specifically, the second locking member 133 further includes an operating portion 1333. The operating portion 1333 is located on the side of the second clamping portion 1332 away from the second rotating portion 1331, and the operating portion 1333, the second clamping portion 1332 and the second rotating portion 1331 are integrally formed or fixedly connected. When the second clamping portion 1332 is clamped with the first pipe fitting 11, the second clamping portion 1332 can be separated from the first pipe fitting 11 by pulling the operating portion 1333, which is beneficial to improving the operation convenience of the second locking member 133.

[0049] Optionally, a magnetic member 1334 is provided inside the second engaging portion 1332, and a magnetic induction member 112 is provided inside the first pipe fitting 11. When the second engaging portion 1332 is engaged with the first pipe fitting 11, at least a part of the projection of the magnetic induction member 112 and the magnetic member 1334 in the radial direction of the first pipe fitting 11 overlaps. Through the above arrangement, the magnetic induction member 112 can sense the magnetic field change caused by the movement of the magnetic member 1334, so as to determine whether the second engaging portion 1332 is engaged with the first pipe fitting 11. Furthermore, when ensuring the engagement between the second locking member 133 and the first pipe fitting 11, the first pipe fitting 11 and the second pipe fitting 12 can be in a working state, thereby improving the working stability of the first pipe fitting 11 and the second pipe fitting 12. Among them, when the second locking member 133 rotates and approaches the first pipe fitting 11, the magnetic member 1334 inside the second engaging portion 1332 will gradually approach the magnetic induction member 112, so that the magnetic induction member 112 can detect the changing magnetic field. Until the second locking member 133 is engaged with the first pipe fitting 11, the magnetic field intensity that the magnetic induction member 112 can detect is the largest, so as to determine whether the second locking member 133 is engaged with the first pipe fitting 11.

[0050] Specifically, the magnetic member 1334 is arranged close to the operating portion 1333, so that the magnetic member 1334 is arranged away from the second rotating portion 1331, so that the rotating distance of the magnetic member 1334 is relatively long, which is beneficial to the magnetic induction member 112 to sense the magnetic field change generated by the movement of the magnetic member 1334, thereby improving the detection accuracy of the magnetic induction member 112.

[0051] It should be noted that the magnetic member 1334 can also be located at any position of the second engaging portion 1332, as long as the magnetic induction member 112 can detect the magnetic field change generated by the movement of the magnetic member 1334.

[0052] Among them, the magnetic member 1334 can be a magnet, and the magnetic induction member 112 can be a magnetic induction sheet, which is not limited in this application.

[0053] Such as Figure 3 、 Figure 4 and Figure 6 As shown, as a realization method, the first pipe fitting 11 is provided with a first matching portion 113 that can be engaged with the first locking member 132 and a second matching portion 114 that can be engaged with the second locking member 133. Both the first matching portion 113 and the second matching portion 114 protrude in a direction away from the first pipe fitting 11, which is beneficial to the engagement between the first locking member 132 and the first matching portion 113, and is beneficial to the engagement between the second locking member 133 and the second matching portion 114.

[0054] Specifically, along the circumferential direction of the first pipe fitting 11, the distance between the first engaging portion 113 and the opening of the rotating groove 111 is less than the distance between the second engaging portion 114 and the opening of the rotating groove 111, so that the first engaging portion 1322 surrounded by the second engaging portion 1332 can be engaged with the first engaging portion 113.

[0055] More specifically, at least a part of the side of the second engaging portion 114 facing away from the first engaging portion 113 protrudes away from the first engaging portion 113. The second engaging portion 1332 is formed with a locking boss portion 1332a. When the second engaging portion 1332 is engaged with the first pipe fitting 11, the locking boss portion 1332a is engaged with the protrusion 1141 of the second engaging portion 114, so that the second locking member 133 can be engaged with the first pipe fitting 11. It can be understood that the fit between the locking boss portion 1332a and the protrusion 1141 of the second engaging portion 114 is an interference fit, which is beneficial to improving the engagement stability between the locking boss portion 1332a and the protrusion 1141 of the second engaging portion 114.

[0056] Among them, the locking boss portion 1332a can be set as a positioning spring ball or a positioning spring piece integrally formed with or fixedly connected to the second engaging portion 1332. The present application does not limit the specific structure of the locking boss portion 1332a.

[0057] As an alternative implementation, the first pipe fitting 11 is further provided with a fixing portion 115 rotatably connected to the locking body 131. Among them, the fixing portion 115 can be two sheet-like structures formed by the first pipe fitting 11 extending in a direction away from the axis of the first pipe fitting 11. An installation hole is provided on the fixing portion 115. A pivot shaft 116 passes through the two sheet-like structures formed by the fixing portion 115 and the connecting end 1312 of the locking body 131, so that the connecting end 1312 of the locking body 131 is rotatably connected to the first pipe fitting 11.

[0058] It should be noted that the pivot shaft 116 can be a pin shaft. After the pin shaft passes through the installation holes on the two sheet-like structures and the connecting end 1312 of the locking body 131, it is clamped with a snap ring, so that the pin shaft will not fall off from the connecting end 1312 and the first pipe fitting 11. The pivot shaft 116 can also be a bolt. After the bolt passes through the installation holes on the two sheet-like structures and the connecting end 1312 of the locking body 131, it is fixed with a nut. The present application does not make a limitation. It can be understood that the above setting can make the connection between the first pipe fitting 11 and the locking mechanism 13 only a pin shaft or bolt connection, which is convenient for the assembly between the first pipe fitting 11 and the locking mechanism 13 and improves the assembly efficiency between the first pipe fitting 11 and the locking mechanism 13.

[0059] Such as Figure 3 and Figure 7As shown in the figure, specifically, the rotation groove 111 has a first opening 1111 for the rotation section 121 to pass through and a second opening 1112 that provides a rotation space for the rotation section 121. The second opening 1112 is formed on the circumferential surface of the first pipe fitting 11. When the second pipe fitting 12 is in the unfolded state, the locking mechanism 13 can cover the second opening 1112, that is, at this time, the locking body 131 covers the second opening 1112.

[0060] Along the circumferential direction of the first pipe fitting 11, the fixing portion 115 and the first engaging portion 113 are located on both sides of the opening of the rotation groove 111. Specifically, along the circumferential direction of the first pipe fitting 11, the fixing portion 115 and the first engaging portion 113 are located on both sides of the second opening 1112. Through the above arrangement, the two ends of the locking body 131 along its extending direction can be respectively arranged close to both sides of the second opening 1112, that is, the connecting end 1312 can be located on one side of the second opening 1112, and the locking end 1313 can be located on the other side of the second opening 1112, so that the locking body 131 can better cover the second opening 1112, thereby improving the locking effect of the locking mechanism 13 on the first pipe fitting 11 and the second pipe fitting 12.

[0061] In this embodiment, pipe fitting connection portions 117 are further formed on the first pipe fitting 11. There are two pipe fitting connection portions 117, and the two pipe fitting connection portions 117 are distributed along the circumferential direction of the first pipe fitting 11 on both sides of the second opening 1112. The pipe fitting connection portions 117 are rotatably connected to the rotation section 121. Among them, the pipe fitting connection portion 117 can be a sheet-like structure extending away from the axis of the first pipe fitting 11, and the pipe fitting connection portion 117 and the rotation section 121 are rotatably connected by a pin or a bolt, that is, fixed by a snap ring after a pin passes through the pipe fitting connection portion 117 and the rotation section 121, or fixed by a nut after a bolt passes through the pipe fitting connection portion 117 and the rotation section 121. The present application does not make any restrictions. It can be understood that the above arrangement can make the connection between the first pipe fitting 11 and the second pipe fitting 12 only a pin or bolt connection, thereby facilitating the assembly between the first pipe fitting 11 and the second pipe fitting 12 and improving the assembly efficiency between the first pipe fitting 11 and the second pipe fitting 12.

[0062] It should be noted that the rotation axis of the rotation section 121 relative to the pipe fitting connection portion 117 is perpendicular to the rotation axis of the locking body 131 relative to the first pipe fitting 11, the rotation axis of the first locking member 132 relative to the locking body 131 is parallel to the rotation axis of the locking body 131 relative to the first pipe fitting 11, and the rotation axis of the second locking member 133 relative to the locking body 131 is also parallel to the rotation axis of the locking body 131 relative to the first pipe fitting 11.

[0063] As an implementation, a buffer pad 1211 is provided on the rotating section 121 of the present application. The buffer pad 1211 is located at the opening of the rotating section 121 facing the rotating groove 111. When at least part of the locking body 131 covers the rotating groove 111, the buffer pad 1211 is located between the rotating section 121 and the locking body 131, so that the buffer pad 1211 can abut against the rotating section 121 and the locking body 131, thereby enabling the buffer pad 1211 to provide buffering between the rotating section 121 and the locking body 131, so as to improve the shock absorption effect between the rotating section 121 and the locking body 131. In addition, when the buffer pad 1211 is located between the rotating section 121 and the locking body 131, the buffer pad 1211 is in a compressed state, so that the buffer pad 1211 can also eliminate the assembly gap between the rotating section 121 and the locking body 131. Among them, the buffer pad 1211 can be made of soft rubber materials such as rubber.

[0064] Specifically, the buffer pad 1211 can be fixed to the rotating section 121 by means of bonding or the like, and the present application does not limit this.

[0065] To improve the waterproof performance between the first pipe fitting 11 and the second pipe fitting 12, a water isolation member 14 for sealing the first pipe fitting 11 is provided in the rotating groove 111 of the present application. The water isolation member 14 is located between the rotating section 121 and the inner wall of the rotating groove 111. Specifically, the second pipe fitting 12 further includes a pipe fitting main body 122, and the rotating section 121 and the pipe fitting main body 122 are fixedly connected or integrally formed. A groove structure is formed at one end of the rotating section 121 facing away from the pipe fitting main body 122, and the water isolation member 14 is located in the groove structure (not shown in the figure), so that the water isolation member 14 is also located in the rotating groove 111, and further enables the water isolation member 14 to seal the gap between one end of the rotating section 121 facing away from the pipe fitting main body 122 and the inner wall of the rotating groove 111.

[0066] Furthermore, at least part of the rotating section 121 protrudes toward the opening of the rotating groove 111 to form a sealing portion 1213. When the second pipe fitting 12 is in the unfolded state, the sealing portion 1213 seals the opening of the rotating groove 111, so that the rotating groove 111 can be sealed by the sealing portion 1213 and the water isolation member 14, thereby improving the waterproof performance between the first pipe fitting 11 and the second pipe fitting 12.

[0067] As an alternative implementation, a through hole 141 for the wire harness to pass through is provided on the water isolation member 14, which is beneficial to the wire harness passing from the first pipe fitting 11 to the second pipe fitting 12, or beneficial to the wire harness passing from the second pipe fitting 12 to the first pipe fitting 11, and further enables a signal transmission loop to be formed in the first pipe fitting 11 and the second pipe fitting 12.

[0068] Such as Figure 5 、 Figure 8 and Figure 9As shown, in the present application, the locking principle of the locking mechanism 13 is as follows:

[0069] When the second pipe fitting 12 is in the unfolded state, the locking body 131 covers the second opening 1112 of the rotating groove 111, thereby fixing the relative position between the second pipe fitting 12 and the first pipe fitting 11. As Figure 8 shown, at this time, the first engaging portion 1322 is engaged with the first engaging portion 113. Under the action of the pre-tightening force of the elastic member 135 on the abutting portion 1321, the first engaging portion 1322 and the first engaging portion 113 always remain in the engaged state. As Figure 9 shown, at the same time, the second engaging portion 1332 is engaged with the second engaging portion 114. Since the fit between the locking boss portion 1332a and the protrusion 1141 of the second engaging portion 114 is an interference fit, the second engaging portion 1332 and the second engaging portion 114 always remain in the engaged state. Among them, the fitting method between the locking boss portion 1332a and the protrusion 1141 includes but is not limited to the above interference fit method. For example, the locking boss portion 1332a can also adopt structures such as a positioning spring ball and a positioning spring piece to remain in the engaged state with the protrusion 1141. After the second engaging portion 1332 is engaged with the second engaging portion 114, the magnetic induction member 112 senses the magnetic field change brought by the magnetic member 1334 in the second engaging portion 1332, so as to judge whether the second engaging portion 1332 is engaged with the second engaging portion 114.

[0070] As Figure 8 shown, when it is necessary to make the second pipe fitting 12 in the folded state, an acting force is applied to the operating portion 1333 to separate the second engaging portion 1332 from the second engaging portion 114, so as to separate the second locking member 133 from the first pipe fitting 11; as Figure 5 shown, at the same time, an acting force towards the locking body 131 is applied to the abutting portion 1321 to move the abutting portion 1321 towards the locking body 131, so as to separate the first engaging portion 1322 from the first engaging portion 113, and further separate the first locking member 132 from the first pipe fitting 11. At this time, the rotating section 121 can rotate in the rotating groove 111, and the axes of the first pipe fitting 11 and the second pipe fitting 12 are not parallel, so that the second pipe fitting 12 is in the folded state, which is beneficial to the storage of the second pipe fitting 12.

[0071] As Figure 10 and Figure 11 shown, the present application also provides an unmanned aerial vehicle 200, and the unmanned aerial vehicle 200 includes the connecting pipe assembly 100 of the present application.

[0072] Specifically, the unmanned aerial vehicle 200 includes a fuselage 21, a fuselage arm 22 connected to the fuselage 21, and an arm 23 rotatably connected to the fuselage arm 22. The arm 23 is used to install a propeller, so that the unmanned aerial vehicle 200 can work properly. The propeller can be driven by a motor, and the motor is connected to the controller of the unmanned aerial vehicle 200 through a wire harness. More specifically, the wire harness can pass through the through hole 141 on the water-proof member 14, so that the wire harness can be electrically connected to the controller of the unmanned aerial vehicle 200 after passing through the first pipe fitting 11 and the second pipe fitting 12.

[0073] Among them, the fuselage arm 22 can be the first pipe fitting 11 of the present application, and the arm 23 can be the second pipe fitting 12 of the present application. Through the above settings, the arm 23 can rotate relative to the fuselage arm 22, so that the arm 23 can be in a working state extending along the same straight line as the fuselage arm 22 and a storage state not parallel to the fuselage arm 22, which is beneficial to reducing the volume of the unmanned aerial vehicle 200 and reducing the packaging size of the unmanned aerial vehicle 200.

[0074] Specifically, the unmanned aerial vehicle 200 further includes a landing gear pipe fitting 24 connected to the fuselage 21 and a landing gear 25 rotatably connected to the landing gear pipe fitting 24. The landing gear pipe fitting 24 can be the first pipe fitting 11 of the present application, and the landing gear 25 can be the second pipe fitting 12 of the present application. Through the above settings, the landing gear 25 can rotate relative to the landing gear pipe fitting 24, so that the landing gear 25 can be in a working state extending along the same straight line as the landing gear pipe fitting 24 and a storage state not parallel to the landing gear pipe fitting 24, which is beneficial to reducing the volume of the unmanned aerial vehicle 200 and reducing the packaging size of the unmanned aerial vehicle 200.

[0075] In this embodiment, the first locking member 132 and the second locking member 133 make the locking between the arm 23 and the fuselage arm 22 more reliable, or the first locking member 132 and the second locking member 133 make the locking between the landing gear 25 and the landing gear pipe fitting 24 more reliable. That is, when the clamping of the first locking member 132 or the second locking member 133 with the first pipe fitting 11 fails, the other locking member still maintains the locking state, so that the unmanned aerial vehicle 200 will not have a crash accident, improving the safety of the unmanned aerial vehicle 200.

[0076] In addition, by adding a magnetic component 1334 to the second locking member 133 and a magnetic induction component 112 to the first pipe fitting 11, it can be prevented that the second locking member 133 and the first pipe fitting 11 are not clamped when the unmanned aerial vehicle 200 is in use, thereby improving the safety of the unmanned aerial vehicle 200. At the same time, the magnetic induction component 112 can also be electrically connected to the controller in the unmanned aerial vehicle 200. Thus, when the second locking member 133 and the first pipe fitting 11 are not locked, an alarm message can be sent to the user through the unmanned aerial vehicle 200 or the remote controller of the unmanned aerial vehicle 200, further enhancing the intelligence and safety of the unmanned aerial vehicle 200.

[0077] It should be understood that for those of ordinary skill in the art, modifications or variations can be made according to the above description, and all such modifications and variations shall fall within the protection scope of the appended claims of this application.
