[0031] As shown in Figures 1-6 The utility model discloses an embodiment proposes a kind of three-lock structures of folding vertical pipe, including upper main body 1 and lower main body 2, upper main body 1 with lower main body 2 are through the first rotating shaft 31 of being set in the same side inside connecting portion 3, upper main body 1 is provided with the convex part 11 in the side away from corresponding connecting portion 3, the upper end surface of convex part 11 is inserted with boss 12, the lower end surface of convex part 11 is L type setting, lower main body 2 is provided with lug portion 21 in the side away from corresponding connecting portion 3, first locking piece 23 is inserted with second rotating shaft 22 in lug portion 21, when upper main body 1 and lower main body 2 are mutually buckled by connecting portion 3, first locking piece 23 is clamped in the lower end surface of convex part 11, lug portion 21 outside is also sleeved with spanner 4, second rotating shaft 22 extends to the outside of lug portion 21 and is inserted into spanner 4, make spanner 4 with second rotating shaft 22 as center of rotation, through hole 41 is formed in spanner 4, second locking piece 42 is movably arranged in through hole 41 by reset spring 43 of bottom, fixed hook 13 is arranged on upper main body 1, when spanner 4 rotates and approaches towards upper main body 1, push second locking piece 42, make it displacement to the top of fixed hook 13, then release second locking piece 42, make it and fixed hook 13 are mutually engaged, complete locking, third rotating shaft 44 is horizontally inserted in the side of spanner 4 towards upper main body 1, third locking piece 45 is sleeved on third rotating shaft 44, when spanner 4 approaches towards main body, third locking piece 45 approaches towards the convex part 11 of upper main body 1 and is finally clamped to the side of convex part 11 close to upper main body 1 under the action of force.

[0032] Specifically, the end of upper main body 1 away from lower main body 2 is sleeved with hollow tubular part 5.

[0033] Specifically, the second locking member 42 comprises a push block 421 and a movable hook 422, the push block 421 is fixedly connected with the movable hook 422, and the movable hook 422 is located on the side of the wrench 4 close to the upper body 1. The push block 421 is movably arranged in the through hole 41 of the wrench 4 through the bottom connecting reset spring 43. Pushing the push block 421 makes the reset spring 43 extend and deform, so that the height of the movable hook 422 is higher than that of the fixed hook 13. When the wrench 4 continuously approaches the upper body 1, the end of the movable hook 422 passes the end of the fixed hook 13, the push block 421 is released, and the reset spring 43 is contracted and reset, so that the movable hook 422 is engaged with the fixed hook 13.

[0034] Specifically, the third locking member 45 can be a hollow ball.

[0035] Specifically, the top of the wrench 4 is bent towards the side away from the upper body 1, which facilitates the user to better operate the wrench 4 to exert force when unlocking or closing.

[0036] Specifically, the top of the wrench 4 is provided with anti-skid lines 46 towards the side of the upper body 1, which increases the friction when the user operates the wrench 4, thereby further enhancing the user's operation ability of the wrench 4.

[0037] Specifically, the lower body 2 is arranged in a C shape, and the closure is completed by the fastening bolts arranged on both sides of the gap. This not only increases the size of the tubular member 5 matched with the lower body 2, but also adjusts the connection strength between the lower body 2 and the matched tubular member 5.

[0038] Specifically, the fixed hook 13 is located above the convex portion 11 of the upper body 1.

[0039] Working principle: when locking, the upper body and the lower body are close to each other through the connecting portion. When the upper body and the lower body abut against each other, the first locking member is pushed to be clamped in the L-shaped groove at the lower part of the convex portion, thereby avoiding the easy separation of the upper body and the lower body. Then the push block is pulled to move towards the upper part of the wrench, driving the movable hook to move upwards together, and the reset spring is extended at the same time. In the process, the third locking member gradually extrudes the boss, and finally passes the boss to be clamped on the side of the convex portion close to the upper body, thereby achieving the purpose of pressing the upper body and the lower body, making the locking of the upper body and the lower body more reliable. When the end of the movable hook passes the end of the fixed hook, the push block is released, and the reset spring is contracted and reset, so that the movable hook is engaged with the fixed hook, and the final locking process is completed.

[0040] When unlocking, the push handle is pulled to make the movable hook separate from the fixed hook, and a force is applied to the wrench to make the third locking member break the friction force between the third locking member and the convex part, so that the wrench is separated and falls down, the first locking member tail is pushed to make it separate from the L-shaped lower part of the convex part, and three unlocking of the upper body and the lower body is completed.

[0041] Each of the embodiments in the specification is described in a progressive manner, and the same or similar parts between the embodiments can be referred to each other, and each embodiment mainly explains the difference from other embodiments. Especially, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the related parts can be referred to the part of the method embodiment.

[0042] The above only describes the embodiments of the utility model, and is not used to limit the utility model. For those skilled in the art, the utility model can have various changes and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the claim range of the utility model.
