[0029] In the description of the present application, unless otherwise explicitly limited, the words such as setting, installing, connecting, etc. should be understood in a broad sense, and the skilled in the art can reasonably determine the specific meaning of the above words in the present application in combination with the specific content of the technical solution.

[0030] The following will be described with reference to Figures 1 to 3 The first aspect of the present application is described in detail below.

[0031] Reference is made to Figure 1According to the telescopic pipe locking device, the handle 310 is swung relative to the locking structure 320, and the handle 310 is separated from the accommodating groove 320a, so that the locking structure 320 releases the pipe wall of the outer pipe 100, thereby releasing the inner pipe 200 from the inner side pipe wall of the outer pipe 100, and the locking structure 320 is in the released state; under the action of an external force, the inner pipe 200 can slide relative to the outer pipe 100 to a preset position, and then the handle 310 is swung relative to the locking structure 320 into the accommodating groove 320a, so that the locking structure 320 drives the pipe wall of the outer pipe 100 to contract and clamp the inner pipe 200, thereby achieving length adjustment of the telescopic pipe.

[0032] In the telescopic pipe locking device, by swinging the handle 310 relative to the locking structure 320, the handle 310 is separated from the accommodating groove 320a, so that the locking structure 320 releases the pipe wall of the outer pipe 100, thereby releasing the inner pipe 200 from the inner side pipe wall of the outer pipe 100, and the locking structure 320 is in the released state, at this time, under the action of an external force, the inner pipe 200 can slide relative to the outer pipe 100 to a preset position, and then by swinging the handle 310 relative to the locking structure 320 into the accommodating groove 320a, so that the locking structure 320 drives the pipe wall of the outer pipe 100 to contract and clamp the inner pipe 200, thereby achieving length adjustment of the telescopic pipe. It can be understood that when the inner pipe 200 is fixed relative to the outer pipe 100 at the preset position, the locking structure 320 is in the locked state, and at this time the handle 310 is at least partially hidden in the accommodating groove 320a, reducing the space occupied by the handle 310, thereby reducing the possibility of interference with the user's use by the part of the handle 310 protruding from the locking structure 320, further improving the user's use effect.

[0033] As Figure 3As shown in the utility model concrete embodiment, the pipe wall of the outer tube 100 is provided with a first gap 110, the first gap 110 is communicated with the internal passage of the outer tube 100, and the locking structure 320 is connected with both ends of the width of the first gap 110 of the outer tube 100 respectively. It can be understood that when the handle 310 swings relative to the locking structure 320 until the handle 310 is partially accommodated in the accommodating groove 320a, the locking structure 320 is driven by the handle 310 to reduce the width size of the first gap 110 of the outer tube 100, the pipe wall of the outer tube 100 is inwardly contracted and clamped, when the handle 310 swings relative to the locking structure 320 and is separated from the accommodating groove 320a, the locking structure 320 releases the outer tube 100, at this time the width size of the first gap 110 of the outer tube 100 is increased, and the outer tube 100 releases the inner tube 200. It can be understood that when the first gap 110 is arranged on the outer tube 100, the deformation amount of the outer tube 100 is increased, so that the outer tube 100 is more easily deformed under the action of the locking structure 320.

[0034] Reference Figure 1 And Figure 2 In some embodiments of the utility model, the locking structure 320 includes a tube clamp 321, the outer tube 100 is arranged in the internal passage of the tube clamp 321, the accommodating groove 320a is arranged on the tube clamp 321, the handle 310 is connected with the tube clamp 321, and the handle 310 can swing relative to the tube clamp 321 to drive the tube clamp 321 to clamp or release the inner tube 200. For example, as shown in the utility model, Figure 2 And Figure 3 The first abutting portion 321a and the second abutting portion 321b are arranged on the tube clamp 321, the second gap 321c that communicates the internal passage of the tube clamp 321 is formed between the first abutting portion 321a and the second abutting portion 321b, and the handle 310 can swing relative to the first abutting portion 321a. It can be understood that in the process of swinging the handle 310 to the accommodating groove 320a of the tube clamp 321, the handle 310 can drive the first abutting portion 321a of the tube clamp 321 to approach the second abutting portion 321b of the tube clamp 321 to reduce the width size of the second gap 321c, the tube clamp 321 is inwardly tightened and clamps the outer tube 100, and drives the outer tube 100 to inwardly contract and clamp the inner tube 200, so that the locking and fixing of the inner tube 200 relative to the outer tube 100 are realized.

[0035] It can be understood that by arranging the tube clamp 321 to clamp the inner tube 200 driven by the outer tube 100, a specific structure does not need to be arranged on the outer tube 100 to lock, and the machining difficulty of the outer tube 100 is reduced.

[0036] Reference Figure 1 And Figure 2In some embodiments of the utility model, the accommodating groove 320a is communicated with the internal passage of the pipe clamp 321, and when the locking structure 320 is in the locked state, the handle 310 is attached to the pipe wall of the outer pipe 100. It can be understood that when the accommodating groove 320a is communicated with the internal passage of the pipe clamp 321, the space of the accommodating groove 320a for accommodating the handle 310 is larger, so that the space occupied by the handle 310 protruding from the pipe clamp 321 can be further reduced.

[0037] As shown in Figure 2 and Figure 3 In some embodiments, the locking structure 320 further comprises an adjusting piece 322, the pipe clamp 321 is provided with a first abutting part 321a and a second abutting part 321b, the first abutting part 321a is slidably sleeved on the adjusting piece 322, the adjusting piece 322 is abutted with the side of the second abutting part 321b away from the first abutting part 321a, the handle 310 comprises an eccentric part 311, the eccentric part 311 is rotatably connected with the adjusting piece 322, and is abutted with the side of the first abutting part 321a away from the second abutting part 321b, when the eccentric part 311 is rotated relative to the adjusting piece 322, the eccentric part 311 pushes the first abutting part 321a to be close to or away from the second abutting part 321b, so that the locking structure 320 is in the locked state or the loosened state.

[0038] It can be understood that under the operation of the user, the handle 310 is rotated relative to the adjusting piece 322 and close to the accommodating groove 320a, because the handle 310 is abutted with the first abutting part 321a, the handle 310 will apply a pushing force to the first abutting part 321a, the first abutting part 321a slides along the adjusting piece 322 and close to the second abutting part 321b, so that the pipe clamp 321 drives the outer pipe 100 to clamp the inner pipe 200; under the operation of the user, the handle 310 is rotated relative to the adjusting piece 322 and away from the accommodating groove 320a, the handle 310 cancels part of the abutting force applied to the first abutting part 321a, the first abutting part 321a slides along the adjusting piece 322 and away from the second abutting part 321b, so that the pipe clamp 321 loosens the outer pipe 100.

[0039] Specifically, the second gap 321c, which connects the inner channel of the pipe clamp 321, is formed between the first abutting part 321a and the second abutting part 321b. It can be understood that, since the first abutting part 321a abuts against the eccentric part 311, when the eccentric part 311 of the handle 310 rotates relative to the adjusting member 322 to make the handle 310 partially accommodated in the accommodating groove 320a, the eccentric part 311 can push the first abutting part 321a to move close to the second abutting part 321b, the width of the second gap 321c is reduced, until the locking structure 320 is in the locked state, and the inner pipe 200 is clamped in the outer pipe 100; when the eccentric part 311 of the handle 310 rotates relative to the adjusting member 322 to make the handle 310 partially separated from the accommodating groove 320a, the first abutting part 321a moves away from the second abutting part 321b, the width of the second gap 321c is increased, until the locking structure 320 is in the released state, at this time, the inner pipe 200 can slide relative to the outer pipe 100.

[0040] With reference to Figure 2 and Figure 3 In some embodiments, the locking structure 320 further comprises a pin shaft 323, the eccentric part 311 is rotationally connected with the pin shaft 323, and the eccentric part 311 can rotate around the axis of the pin shaft 323; the pin shaft 323 is fixedly connected with the adjusting member 322, and the pin shaft 323 can rotate around the axis of the adjusting member 322 to drive the adjusting member 322 to rotate. It can be understood that, since the eccentric part 311 is rotationally connected with the pin shaft 323, and the pin shaft 323 is fixedly connected with the adjusting member 322, when the eccentric part 311 rotates around the axis of the pin shaft 323, the eccentric part 311 can rotate relative to the adjusting member 322.

[0041] Specifically, the axis of the pin shaft 323 is perpendicular to the axis of the adjusting member 322.

[0042] As Figure 2 and Figure 3As shown, in one embodiment, the adjusting member 322 comprises a threaded screw 322a and a nut 322b, the first abutting part 321a and the second abutting part 321b are sleeved on the threaded screw 322a, the nut 322b abuts against the side of the second abutting part 321b away from the first abutting part 321a, the threaded screw 322a is fixedly connected with the pin shaft 323, and the pin shaft 323 can rotate around the axis of the threaded screw 322a to drive the threaded screw 322a to rotate. It can be understood that the user rotates the nut 322b to make the nut 322b close to the first abutting part 321a, and since the nut 322b abuts against the side of the second abutting part 321b away from the first abutting part 321a, the nut 322b can drive the second abutting part 321b to close to the first abutting part 321a along the threaded screw 322a, so as to reduce the inner diameter of the pipe clamp 321, increase the clamping degree of the pipe clamp 321 to the outer pipe 100, and thus realize the adjustment of the clamping degree of the pipe clamp 321 to the outer pipe 100.

[0043] With reference to Figure 2 And Figure 3 In some embodiments of the utility model, the handle 310 further comprises a connecting part 312 and a hand holding part 313, the eccentric part 311 and the hand holding part 313 are connected through the connecting part 312, when the locking structure 320 is in the locked state, the connecting part 312 is accommodated in the accommodating groove 320a, and the hand holding part 313 is located outside the accommodating groove 320a. It can be understood that by accommodating the connecting part 312 in the accommodating groove 320a and locating the hand holding part 313 outside the accommodating groove 320a, the space occupied by the handle 310 is reduced, and the user can operate the handle 310 conveniently.

[0044] It can be understood that by arranging the hand holding part 313 at the end of the connecting part 312 away from the eccentric part 311, a labor-saving lever structure is formed between the handle 310 and the pipe clamp 321, and the user can use the handle 310 conveniently.

[0045] As shown in Figure 2 And Figure 3 In some embodiments of the utility model, the outer pipe 100 is provided with a clamping groove 120, and the pipe clamp 321 is provided with a clamping protrusion 321d clamped in the clamping groove 120. It can be understood that by clamping the clamping protrusion 321d of the pipe clamp 321 in the clamping groove 120 of the outer pipe 100, the pipe clamp 321 can be positioned on the outer pipe 100 quickly, and the user can assemble the pipe clamp 321 on the outer pipe 100 conveniently.

[0046] In the embodiment of the utility model, the first gap 110 is communicated with the second gap 321c. It can be understood that the first gap 110 of the outer tube 100 and the second gap 321c of the pipe clamp 321 are communicated through the clamping cooperation of the outer tube 100 and the pipe clamp 321, and at this time, when the width size of the second gap 321c is adjusted through the handle 310, it is more convenient to adjust the width size of the first gap 110 through the pipe clamp 321.

[0047] Reference Figure 1 And Figure 3 In some embodiments, the clamping groove 120 is communicated with the internal passage of the outer tube 100, the pipe wall of the inner tube 200 is provided with a guide groove 210 extending along the axial direction of the inner tube 200, the clamping protrusion 321d is partially arranged in the guide groove 210, and the clamping protrusion 321d is arranged in close contact with each groove wall of the guide groove 210. It can be understood that when the inner tube 200 slides along the outer tube 100, the clamping protrusion 321d slides in the guide groove 210, and since the clamping protrusion 321d is in close contact with each groove wall of the guide groove 210, the sliding of the clamping protrusion 321d is more stable, so that the sliding of the inner tube 200 is more stable and smooth, and the possibility of shaking of the inner tube 200 during sliding is reduced, thereby hindering the sliding.

[0048] According to the bicycle of the second aspect of the utility model, the telescopic pipe locking device of the first aspect of the utility model is adopted in the bicycle, the possibility that the handle 310 occupies more space and affects the use of the user is reduced, and the use effect of the user is improved.
