DETAILED DESCRIPTION

[0020] 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 in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0021] In this embodiment, Figure 1 As shown, it includes a first vehicle tube 1 and a second vehicle tube 2, and the first vehicle tube 1 and the second vehicle tube 2 are hingedly connected so that the first vehicle tube 1 and the second vehicle tube 2 can rotate relative to each other. In this embodiment, a connecting block 8 is provided between the first vehicle tube 1 and the second vehicle tube 2, and a mounting groove 13 for accommodating the connecting block 8 is opened on the same side of the first vehicle tube 1 and the second vehicle tube 2. The mounting groove 13 spans the first vehicle tube 1 and the second vehicle tube 2, and two mutually parallel rotating shafts are provided on the connecting block 8. The first vehicle tube 1 and the second vehicle tube 2 are respectively provided with axial holes that rotate with the corresponding rotating shafts, so that the first vehicle tube 1 and the second vehicle tube 2 can realize relative rotation through the connecting block 8, and the first vehicle tube 1 and the second vehicle tube 2 can respectively rotate relative to the connecting block 8 through their respective rotating points, so that the first vehicle tube 1 and the second vehicle tube 2 can be folded relative to each other.

[0022] The first and second mounting grooves 3 and 4 are respectively provided on the opposite end surfaces of the first and second vehicle tubes 1 and 2, a movable locking block 5 is provided in the first mounting groove 3, a locking groove 41 is provided in the second mounting groove 4, and a locking tooth 53 is provided on the locking block 5 to form a buckle with the locking groove 41. The first vehicle tube 1 is provided with a receiving groove 6 communicating with the first mounting groove 3 on the side away from the rotation connection point, and a triggering part 7 linked to the locking block 5 is provided in the receiving groove 6. A mounting hole 54 is opened at one end of the locking block 5 away from the triggering part 7, and the mounting hole 54 is flush with the end surface of the first vehicle tube 1. A spring 9 is provided in the mounting hole 54, one end of the spring 9 abuts against the bottom end of the mounting hole 54, and the other end abuts against the inner wall of the first mounting groove 3. Under the push of the spring 9, the locking tooth 53 of the locking block 5 is always inserted into the locking groove 41 to form a buckle, forming a rotation limit for the first vehicle tube 1 and the second vehicle tube 2, that is, when the spring 9 presses the locking block 5 on one side of the first mounting groove 3, the locking tooth 53 and the locking groove 41 are always in a buckle locking state. In this embodiment, the locking block 5 is a block structure, which includes a block body 51, and the block body 51 is a rectangular block structure.

[0023] A limiting protrusion 52 is provided on the bottom edge of the block body 51, and the limiting protrusion 52 and the block body 51 are designed as an integral whole. A limiting groove 31 is provided on the side wall of the first mounting groove 3. When the block body 51 is compressed by the spring 9, the limiting protrusion 52 is inserted into the limiting groove 31, and the limiting protrusion 52 and the limiting groove 31 form an axial limit to prevent the locking block 5 from being separated from the first mounting groove 3. The limiting protrusion 52 is located at the bottom edge of the block body 51 and faces the end away from the mounting hole 54. The locking tooth 53 is located at the top edge of the block body 51 and is arranged in the same direction as the limiting protrusion 52, that is, the limiting protrusion 52 and the locking tooth 53 are respectively distributed on the upper and lower parts of the block body 51 and are both facing the direction of the trigger part 7. In this way, after the locking tooth 53 and the locking groove 41 are snapped, the block body 51 will not axially separate from the first mounting groove 3.

[0024] The triggering part 7 is a pressing block 71, one end of the pressing block 71 is connected to the locking block 5, and the other end forms a pressing surface 72, and the pressing surface 72 is flush with the opening of the accommodating groove 6. When the pressing surface 72 is directly pressed, the pressing block 71 overcomes the force of the spring 9, so that the locking block 5 moves in the first mounting groove 3, so that the locking tooth 53 of the locking block 5 is disengaged from the locking groove 41, and it is in the unlocked state at this time. The first vehicle tube 1 and the second vehicle tube 2 can rotate relative to each other. When the pressing force is removed, the pressing block 71 returns to the position in the locked state under the action of the restoring force of the spring 9. In this embodiment, the locking tooth 53 is a convex structure extending along the length direction of the block structure, which is designed as an integral part with the block structure, and the bottom surface of the locking tooth 53 is a horizontal surface. When the horizontal surface of the bottom and the horizontal top surface of the locking groove 41 are in contact with each other, a buckle is formed.

[0025] It should be noted that, in the present embodiment, the front end of the locking tooth 53 is tilted downward to form an inclined surface, and the inner wall of the corresponding position of the tooth groove is also tilted downward to form an inclined surface in the same direction. When the first tube 1 and the second tube 2 are folded, the locking block 5 is in a locked state under the action of the spring 9. When the first tube 1 and the second tube 2 need to be docked, it is only necessary to rotate the second tube 2 to dock it onto the first tube 1. When the end surfaces of the first tube 1 and the second tube 2 are docked, it is only necessary to press the first tube 1, and the inclined surface of the locking groove 41 will buckle along the inclined surface of the locking tooth 53, thereby achieving buckling without pressing the trigger part 7.

[0026] The trigger part 7 is located in the receiving groove 6, and the pressing surface 72 of the trigger part 7 is complementary to the opening shape of the receiving groove 6, so that the trigger part 7 can be hidden in the receiving groove 6, so that after the first vehicle tube 1 and the second vehicle tube 2 are connected, the trigger part 7 will not bulge out and affect the overall appearance.

[0027] In addition, a protrusion 11 or a groove 12 is provided on the end face of the first vehicle tube 1, and a corresponding groove 12 or a protrusion 11 is provided on the end face of the second vehicle tube 2, so that after the first vehicle tube 1 and the second vehicle tube 2 are connected, their end faces form a concave and convex positioning to strengthen the connection between the first vehicle tube 1 and the second vehicle tube 2.

[0028] Furthermore, the protrusion and the groove 12 are respectively located on both sides of the receiving groove 6 of the corresponding vehicle tube, and the groove 12 is communicated with the installation groove 13 of the corresponding vehicle tube, so that the first vehicle tube 1 and the second vehicle tube 2 are more stable after docking.

[0029] The first mounting groove 3 and the second mounting groove 4 are arranged opposite to each other. When the first vehicle tube 1 and the second vehicle tube 2 are buckled, the first mounting groove 3 and the second mounting groove 4 are combined into a complete mounting groove 13 in half. The locking block 5 is distributed in half in the first mounting groove 3 and the second mounting groove 4, so that the locking block 5 not only plays a locking role, but also plays a certain supporting and positioning role for the two vehicle tubes, so that the two vehicle tubes are more stable after docking.

[0030] The accommodating groove 6 and the first mounting groove 3 are transitionally connected by a transition groove 10. In this embodiment, the transition groove 10 is a square groove, and the locking block 5 extends out of a mounting portion 73. The mounting portion 73 is a square block structure. After the mounting portion 73 is installed and passes through the transition groove 10, it is connected to the locking block 5 through a fastener, so that when the locking block 5 is pressed and moved along the first mounting groove 3, the mounting portion 73 and the transition groove 10 also move accordingly. The cooperation between the mounting portion 73 and the transition groove 10 plays a positioning and guiding role in the movement of the locking block 5, making the movement of the locking block 5 more stable.

[0031] Furthermore, a guide groove is provided at the bottom of the first mounting groove 3 along the moving direction of the locking block 5 , and the bottom of the mounting portion 73 fits into the guide groove, so that the mounting portion 73 can reciprocate along the guide groove, making the movement of the locking block 5 more stable.

[0032] In addition, there are two springs 9 and two corresponding mounting holes 54, which are evenly distributed at one end of the locking block 5, so that the locking and movement of the locking block 5 are more stable.

[0033] The present utility model is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all those having the same or similar technical solutions as the present application fall within the protection scope of the present utility model.
