In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1 to 3, an in-tube locking structure includes a first rotating body 100 and a second rotating body 200, the first rotating body 100 is provided with a first cylinder 110 and a second cylinder 120, the first cylinder 110 and the second cylinder 120 are arranged in a non-coaxial manner, and the first cylinder 110 is connected with an inner tube and blocks the inner wall of the inner tube; the second rotator 200 and the first cylinder 110 are coaxially arranged, the second rotator 200 is provided with a linkage hole 201, the linkage hole 201 and the second cylinder 120 are coaxially arranged, that is, the linkage hole 201 and the second rotator 200 are different centers of circles, and the linkage hole 201 is not arranged at the center of the second rotator 200, so that the upper and lower surfaces of the second rotator 200 are in a ring shape with uneven thickness, the second rotator 200 is sleeved on the second cylinder 120 through the linkage hole 201, the diameter of the second rotator 200 is larger than that of the first rotator 100, the first rotator 100 is arranged in an outer tube to enable the second rotator 200 to clamp the inner wall of the outer tube, that is, the first rotator 100 is arranged in the outer tube, wherein the second rotator 200 is in contact with the inner wall of the outer tube to generate friction force; the first rotator 100 is provided with a first clamping strip 121, the second rotator 200 is provided with a clamping groove 202 corresponding to the first clamping strip 121, and the length of the clamping groove 202 is half of the circumference of the second rotator 200, so that the first clamping strip 121 is conveniently limited when the first clamping strip 121 moves to a certain position. When the inner pipe is rotated, the first cylinder 110 and the inner pipe rotate in a concentric circle, the second cylinder 120 is not coaxial with the first cylinder 110, the second cylinder 120 rotates around the axis of the first cylinder 110, the second rotor 200 is sleeved outside the second cylinder 120 through the linkage hole 201, therefore, when the first clamping strip 121 moves from one side of the clamping groove 202 to the other side, the process that the second cylinder 120 extrudes or keeps away from the inner wall of the second rotor 200 is realized, when the second rotor 200 is extruded to generate expansion locking of the outer pipe, the locking of the two pipes is realized, when the second cylinder 120 does not extrude the second rotor 200, the inner pipe continues to rotate, the first clamping strip 121 can abut against one side of the clamping groove 202 to drive the second rotor 200 to rotate along with the first rotor 100, and the inner pipe and the outer pipe are rotatably connected. When the first locking strip 121 moves from the end with the thickest annular surface of the second rotor 200 to the end with the thinnest annular surface, the second cylinder 120 gradually moves from the position with the thinner annular surface to the position with the thicker annular surface and presses the inner wall of the second rotor 200, and the second rotor 200 expands and locks the outer tube after being pressed.
The effect that the outer tube and the rotation inner tube reach is the same in the rotation, when rotating the outer tube, because the outer wall of the second body 200 of rotating supports the inner wall of outer tube, consequently the second body 200 of rotating and the outer tube do concentric circle and rotate, because linkage hole 201 and second body 200 of rotating are decentraction, consequently first card strip 121 realizes the second body 120 extrusion or keeps away from the process that the second body 200 was rotated when moving to the opposite side from one side of draw-in groove 202, it takes place inflation locking outer tube to be extruded when the second body 200 of rotating, it fixes two body locks to have realized, when the second body 120 does not extrude the second body 200 of rotating, continue rotatory inner tube, first card strip 121 can support draw-in groove 202 one side and drive the second and rotate together with first body 100 of rotating, make inner tube and outer tube rotate and connect.
In the above technical solution, the first rotator 100 and the second rotator 200 are both made of elastic materials, the first rotator 100 and the second rotator 200 made of elastic materials are convenient for clamping inner tubes and outer tubes, and the second rotator 200 and the outer tubes are only contacted by friction force and are not fixedly connected. When the second rotating body 200 is not extruded by the second column body 120, the inner tube continues to rotate, the first clamping strip 121 can abut against one side of the clamping groove 202 to drive the second rotating body 200 to rotate along with the first rotating body 100, so that the inner tube and the outer tube are rotatably connected, and the effect that the outer tube and the inner tube are equivalent to telescopic rods is achieved.
The first rotating body 100 is further provided with a third cylinder 130, the third cylinder 130 is arranged between the first cylinder 110 and the second cylinder 120, the diameter of the third cylinder 130 is larger than that of the first cylinder 110, and the third cylinder 130 is used for preventing the inner pipe from sliding towards the second cylinder 120 when the inner pipe is sleeved on the first cylinder 110.
A second clamping strip 111 is arranged between the first column body 110 and the third column body 130, and it can be understood that the inner tube is provided with a clamping groove adapted to the second clamping strip 111, and when the inner tube is rotated, the first clamping strip 121 can clamp the inner wall of the clamping groove 202 to prevent the inner tube from slipping.
The first rotor 100 is further provided with a fourth cylinder 140 and a fifth cylinder 150, the fourth cylinder 140 is arranged at the end of the second cylinder 120, the fifth cylinder 150 is arranged at the end of the fourth cylinder 140, the diameter of the fourth cylinder 140 is the same as that of the first cylinder 110, the diameter of the fifth cylinder 150 is the same as that of the third cylinder 130, and the fourth cylinder 140 and the fifth cylinder 150 play a role in increasing the strength of the second cylinder 120 and simultaneously play a role in preventing the second rotor 200 from sliding out of the second cylinder 120.
The diameter of the first cylinder 110 is larger than that of the second cylinder 120, so that the second cylinder 120 can rotate within the diameter of the first cylinder 110 with enough space, and at the same time, a certain space is provided for the second rotator 200 to be sleeved on the second cylinder 120.
The first clamping strip 121 and the second clamping strip 111 do not protrude out of the periphery of the third cylinder 130, so that the first clamping strip 121 and the second clamping strip 111 are prevented from clamping the inner wall of the outer pipe, and the relative movement of the outer pipe and the inner pipe is prevented from being blocked.
The second body 200 of turning is equipped with breach 203, and the design of breach 203 makes the second column 120 when extrudeing the second body 200 of turning, and the second body 200 of turning takes place the shape change greatly, and the effect of locking the outer tube is better.
The second rotator 200 is provided with a groove 204, and the groove 204 is opposite to the notch 203, which is more beneficial to the deformation of the second rotator 200.
