Technical Field

[0001] The utility model relates to the technical field of telescopic structures, in particular to a telescopic structure for a handlebar of a vehicle frame. Background Technique

[0002] Most of the adjustable structures of the handlebars of existing vehicle frames adopt a telescopic structure of tube within tube under the handlebar riser and are fixed by clamping members, such as the height-adjustable bicycle handlebar disclosed in the application number 200420016647.5.

[0003] Both the tube and the tube sleeve of the existing handlebar telescopic structure are made of metal. After long-term use, the outer side wall of the tube will be scratched, affecting the appearance. And in order to prevent the outer side wall of the tube from rusting, an electroplated layer is provided. However, when the outer side wall of the tube is scratched, the electroplated layer will also be damaged, and the outer side wall of the tube is prone to rust, affecting the service life. Content of the Utility Model

[0004] The purpose of the utility model is to provide a telescopic structure for a handlebar of a vehicle frame to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A telescopic structure for a handlebar of a vehicle frame, including a tube sleeve, a filling member is installed at the top end inside the tube sleeve, the filling member is made of plastic material, and a tube is movably installed on the top of the tube sleeve.

[0006] By adopting the above technical solution, since the filling member is arranged between the tube sleeve and the tube, when the tube moves in the tube sleeve, the filling member can prevent the inner wall of the tube sleeve from scratching the outer wall of the tube.

[0007] Preferably, the length of the tube sleeve is slightly longer than the length of the tube.

[0008] By adopting the above technical solution, the length of the tube sleeve is slightly longer than the length of the tube, so that the tube can be completely received inside the tube sleeve.

[0009] Preferably, a groove is opened at the top end inside the tube sleeve, and the size of the groove on the tube sleeve is adapted to the size of the filling member.

[0010] By adopting the above technical solution, since the groove is annular and the size of the groove is adapted to the size of the filling member, the groove can stably install the filling member inside the tube sleeve, and when the tube moves in the tube sleeve, the filling member will not be displaced due to friction, and it can prevent the filling member from falling off from inside the tube sleeve.

[0011] Preferably, the inner ring size of the tube sleeve is slightly larger than the outer ring size of the tube, the filling member is annular and the inner ring size of the filling member is adapted to the outer ring size of the tube.

[0012] By adopting the above technical solution, the size of the inner ring of the pipe sleeve is slightly larger than that of the outer ring of the pipe. When the pipe moves, the pipe sleeve will not scratch the outer wall of the pipe, and the filling piece contacts the outer wall of the pipe. The filling piece can be sleeved on the outer surface of the pipe. While the pipe moves inside the pipe sleeve, the filling piece can move along the outer surface of the pipe.

[0013] Preferably, a clamping piece is arranged at the top of the outer surface of the pipe sleeve, and a fixing structure is arranged at the bottom of the pipe sleeve.

[0014] By adopting the above technical solution, the clamping piece can squeeze the filling piece, thereby fixing the extending length of the pipe in the pipe sleeve, and can prevent the pipe from shaking or rotating on the pipe sleeve. The fixing structure is connected to the hub. There is a notch at the top of the outer surface of the sleeve. When the clamping piece is installed, the notch on the sleeve is covered. When the clamping piece contracts, the size of the notch shrinks, and the size of the top of the outer surface of the sleeve shrinks, so that the sleeve can squeeze the filling piece, and the filling piece can squeeze the pipe, thereby firmly fixing the pipe on the pipe sleeve. When the user uses it, there will be no rotation or shaking between the pipe and the pipe sleeve, further reducing the scratching between the pipe sleeve and the pipe.

[0015] Preferably, a handlebar is arranged at the top of the pipe.

[0016] By adopting the above technical solution, a handlebar is arranged at the top of the pipe. With the assistance of the handlebar, the telescopic structure can be driven to rotate, and the user can pull out or retract the pipe from inside the pipe sleeve through the handlebar.

[0017] Compared with the prior art, the beneficial effects of the present utility model are:

[0018] 1. For the handlebar telescopic structure of the vehicle frame, a filling piece is arranged at the top end inside the pipe sleeve. Since the filling piece has ductility and low stiffness, when the pipe moves inside the pipe sleeve, the damage degree of the plating layer on the outer side wall of the pipe can be reduced.

[0019] 2. For the handlebar telescopic structure of the vehicle frame, since the filling piece is located between the pipe and the pipe sleeve, when the clamping piece is fixed, the filling piece can further play a fixing role, preventing the pipe from rotating and shaking, and reducing the damage degree of the plating layer.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1-3 , an embodiment provided by the present invention: a handlebar telescopic structure for a vehicle frame, including a pipe sleeve 1. A filling member 2 is installed at the top end inside the pipe sleeve 1. The filling member 2 is made of plastic. A pipe 3 is movably installed at the top of the pipe sleeve 1. Since the filling member 2 is arranged between the pipe sleeve 1 and the pipe 3, when the pipe 3 moves in the pipe sleeve 1, the filling member 2 can prevent the inner wall of the pipe sleeve 1 from scratching the outer wall of the pipe 3. And when the filling member 2 is squeezed, it can completely fill the gap between the pipe sleeve 1 and the pipe 3, so as to avoid rotation or shaking between the pipe sleeve 1 and the pipe 3.

[0026] In this embodiment, the length of the pipe sleeve 1 is slightly longer than the length of the pipe 3, so that the pipe 3 can be completely received inside the pipe sleeve 1, achieving the purpose of storage.

[0027] In this embodiment, a groove is opened at the top end inside the pipe sleeve 1. The size of the groove on the pipe sleeve 1 is adapted to the size of the filling member 2. Since the groove is annular and the size of the groove is adapted to the size of the filling member 2, the groove can stably install the filling member 2 inside the pipe sleeve 1. And when the pipe 3 moves in the pipe sleeve 1, the filling member 2 will not shift in position due to friction, and it can prevent the filling member 2 from falling off from the inside of the sleeve 1.

[0028] In this embodiment, the inner ring size of the pipe sleeve 1 is slightly larger than the outer ring size of the pipe 3. The filling member 2 is annular and the inner ring size of the filling member 2 is adapted to the outer ring size of the pipe 3. The inner ring size of the pipe sleeve 1 is slightly larger than the outer ring size of the pipe 3. When the pipe 3 moves, the pipe sleeve 1 will not scratch the outer wall of the pipe 3. And the filling member 2 is in contact with the outer wall of the pipe 3. The filling member 2 can be sleeved on the outer surface of the pipe 3. When the pipe 3 moves in the pipe sleeve 1, the filling member 2 can move along the outer surface of the pipe 3, which can avoid the situation of touching when the pipe 3 moves inside the pipe sleeve 1.

[0029] In this embodiment, a clamping member is provided at the top of the outer surface of the sleeve 1, and a fixing structure is provided at the bottom of the sleeve 1. The clamping member can squeeze the filling member 2, thereby fixing the extending length of the pipe 3 in the sleeve 1, and can prevent the pipe 3 from shaking or rotating on the sleeve 1. The fixing structure is connected to the hub. A notch is provided at the top of the outer surface of the sleeve 1. When the clamping member is installed, the notch on the sleeve 1 is covered. When the clamping member contracts, the size of the notch shrinks, and the size of the top of the outer surface of the sleeve 1 shrinks, so that the sleeve 1 can squeeze the filling member 2, and the filling member 2 can squeeze the pipe 3, thereby stably and firmly installing the pipe 3 on the sleeve 1. When the user uses it, there will be no rotation or shaking between the pipe 3 and the sleeve 1, further reducing the scratching between the sleeve 1 and the pipe 3, thereby being able to reduce the damage degree of the electroplating on the outer wall of the pipe 3. Since the filling member 2 is made of plastic and has low rigidity, when the filling member 2 moves on the outer surface of the pipe 3, it will not damage the electroplating layer on the outer surface of the pipe 3.

[0030] In this embodiment, a handlebar is provided at the top of the pipe 3. With the assistance of the handlebar, the telescopic structure can be driven to rotate, and the user can facilitate the retraction or extension of the pipe 3 into or out of the sleeve 1 with the assistance of the handlebar.

[0031] Working principle: When the pipe 3 is pulled out or retracted into the sleeve 1 with the assistance of the handlebar, through the cooperation of the filling member 2, the contact between the sleeve 1 and the pipe 3 can be avoided, thereby preventing the outer wall of the pipe 3 from being scratched by the sleeve 1, and further avoiding the damage of the electroplating layer on the side wall of the outer surface of the pipe 3, and prolonging the service life of the pipe 3. When the extending length of the pipe 3 is determined, the user contracts the clamping member, causing the notch at the top of the outer surface of the sleeve 1 to shrink, thereby squeezing the top of the sleeve 1, shortening the size of the top of the sleeve 1, and further squeezing the filling member 2 at the top end inside the sleeve 1. Since the filling member 2 is made of plastic, the rigidity of the filling member 2 is low. Therefore, the filling member 2 can squeeze the outer wall of the pipe 3, so that the pipe 3 can be stably and firmly fixed inside the sleeve 1. During the user's use, there will be no violent rotation or shaking between the sleeve 1 and the pipe 3, and it can avoid the severe damage caused by repeated scratching at the connection between the pipe 3 and the sleeve 1. At the same time, the filling member 2 can also play a protective role, further protecting the electroplating layer at the connection of the outer surface of the pipe 3. And when the pipe 3 moves in the sleeve 1, the filling member 2 can be stably and firmly connected to the sleeve 1 through the groove, preventing the filling member 2 from detaching from the sleeve 1.

[0032] For those skilled in the art, the present utility model is not limited to the details of the above exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or scope of the present utility model. Therefore, the embodiments of the present utility model are exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be construed as limiting the claims involved.
