Referring to fig. 1 and 2, fig. 1 is a schematic perspective view illustrating a seat bar anti-theft structure 100 applied to a middle tube C1 according to a first embodiment of the present invention, and fig. 2 is an exploded schematic view illustrating the seat bar anti-theft structure 100 and the middle tube C1 of the first embodiment of fig. 1. The seat post anti-theft structure 100 is disposed on a middle tube C1 of a bicycle (not shown in the first embodiment), the seat post anti-theft structure 100 includes a seat post 110 and a seat post clip 120, the seat post 110 is movably inserted into the middle tube C1 and includes a limiting groove 113, and the seat post clip 120 includes a retaining ring 121, a radial through hole 122, an elastic positioning element 124 and an anti-theft screw 123. The retaining ring 121 is sleeved at one end of the middle pipe C1, the radial through hole 122 is located in the retaining ring 121 and correspondingly communicated with the hole C11 of the middle pipe C1, and the elastic positioning member 124 is movably accommodated in the radial through hole 122 and protrudes into the hole C11; the anti-theft screw 123 is screwed in the radial through hole 122 to limit the elastic positioning member 124 in the radial through hole 122. When the seat post 110 moves toward the end along an axial direction I1 (shown in fig. 3) relative to the middle tube C1, the elastic positioning element 124 abuts against the limiting groove 113 and is limited by the limiting groove 113, so as to prevent the seat post 110 from separating from the middle tube C1.
Therefore, the elastic positioning element 124 can cooperate with the limiting groove 113 to block the seat post 110 from being separated from the middle pipe C1, and the anti-theft screw 123 can limit the elastic positioning element 124 in the radial through hole 122, and the elastic positioning element 124 cannot be removed unless a special tool is used to remove the anti-theft screw 123, so that the seat post 110 can be effectively prevented from being stolen. Details of the seat post anti-theft structure 100 will be described later.
Referring to fig. 3 and 4 together with fig. 2, fig. 3 is a schematic cross-sectional view of the seat post anti-theft structure 100 and the middle tube C1 of the first embodiment of fig. 1, and fig. 4 is a schematic cross-sectional view of the seat post anti-theft structure 100 and the middle tube C1 of the first embodiment of fig. 1. The seat post 110 is configured to be disposed on a seat cushion (not shown in the first embodiment) of a bicycle, and the seat post 110 further includes a lower tube 112, an upper tube 111 and a height adjusting mechanism 114, the upper tube 111 is movably inserted into the lower tube 112, the height adjusting mechanism 114 is disposed inside the upper tube 111 and the lower tube 112, the height adjusting mechanism 114 is actuated to allow the upper tube 111 to move relative to the lower tube 112, and the limiting groove 113 is disposed on the lower tube 112 and has a circular groove structure.
Specifically, the seat post 110 may further include a pivoted cam 115, and the height adjustment mechanism 114 may include an actuating rod 1141, a tube (not shown), a valve (not shown) and a piston (not shown), the tube contains a fluid, the actuating rod 1141 extends into the tube, when the cam 115 is connected to the cable, the cam 115 pushes the actuating rod 1141 to open the valve, and the fluid flows relative to the piston to generate a relative displacement between the upper tube 111 and the lower tube 112. In other embodiments, the height adjustment mechanism can be driven by the electrical control unit, and the motor is actuated by a wireless or wired signal, so as to achieve the effect of pushing the actuating rod to move upwards to open the valve. Alternatively, the seat post may be formed of a hollow tube, not limited to the above disclosure.
The middle tube C1 may include a groove C12, the groove C12 is located at the end, so when the seat post clip 120 is sleeved on the end, the wall of the middle tube C1 can be tightened and the gap of the groove C12 can be reduced, thereby fixing the seat post 110 and the middle tube C1. The retaining ring 121 has a C-shaped ring structure, and the seat post clamp 120 may further include a wrench (not shown) pivotally connected to the retaining ring 121, the wrench being actuated to clamp or unclamp the retaining ring 121, and in the first embodiment, the radial through hole 122 is located on a side of the retaining ring 121 adjacent to the wrench and can be protected by the wrench.
The radial through hole 122 penetrates through the body of the retaining ring 121, the elastic positioning element 124 may include a pin 1241 and an elastic element 1242, the pin 1241 is located in the radial through hole 122 and selectively abuts against the limiting groove 113, and the elastic element 1242 is accommodated in the radial through hole 122 and abuts against between the anti-theft screw 123 and the pin 1241.
As shown in fig. 3, the pin 1241 may comprise a head 1241a and a body 1241b, the body 1241b is integrally connected to the head 1241a, the radial bore 122 may comprise a first section and a second section connected to each other, the second section being adjacent to the middle tube C1 and having a smaller inner diameter such that the body 1241b of the pin 1241 may pass through the second section and protrude into the hole C11 of the middle tube C1, and the head 1241a is retained in the first section. Therefore, when the position-limiting groove 113 of the seat post 110 is not aligned with the elastic positioning element 124, the elastic element 1242 is compressed, the body 1241b of the pin 1241 abuts against the outer wall of the seat post 110, and the seat post 110 is not limited by the elastic positioning element 124, so that after the seat post clamp 120 is released, the seat post 110 can move relative to the middle tube C1 to adjust the height.
On the contrary, as shown in fig. 4, when the seat post 110 is moved to a certain height to align the elastic positioning element 124 with the limiting groove 113, the elastic element 1242 is reset to push the pin 1241 outwards, so that the body 1241b protrudes into and abuts against the limiting groove 113, and at this time, the seat post 110 cannot move upwards any more, unless the engagement state of the elastic positioning element 124 and the limiting groove 113 is released, the seat post 110 cannot be pulled out of the middle tube C1. In other embodiments, the upper wall of the position-limiting groove may have an inclined surface structure, or the surface of the pin may have a one-way inclined surface structure, or the upper R angle of the pin may be larger than the lower R angle, so that the elastic positioning member may be pressed to retract when the seat post moves downward, and thus the seat post may be prevented from moving upward but not moving downward.
The anti-theft screw 123 may include a socket 1231 for a tool (not shown) to be inserted into, and the cross-sectional shape of the socket 1231 may be triangular. Therefore, after the wrench is opened, if the user holds a special tool corresponding to the insertion hole 1231, the anti-theft screw 123 can be detached, and at this time, the elastic positioning element 124 is not pressed by the anti-theft screw 123 and can exit the limiting groove 113, so that the seat post 110 can be pulled out of the middle tube C1. In this way, since the insertion hole 1231 of the anti-theft screw 123 has an irregular cross-sectional shape, the anti-theft screw 123 cannot be detached at will, and therefore the engagement between the elastic positioning member 124 and the limiting groove 113 cannot be released, and the seat post 110 can be effectively prevented from being stolen. In other embodiments, the cross-sectional shape of the insertion hole may be polygonal other than hexagonal, or polygonal including middle protruding points, or star-shaped, irregular, etc., without being limited to the above disclosure.
Accordingly, the elastic positioning element 124 has elasticity, so when it is not aligned with the limiting groove 113, it will elastically abut against the seat post 110 without interfering with the height adjustment of the seat post 110. Furthermore, in the manufacturing process, the recessed limiting groove 113 can be formed at the lower end of the seat post 110 by using a lathe, so that the manufacturing process is simple. In addition, the seat post 110 itself does not need to be additionally made into a longitudinal groove structure, and the structural strength can be maintained.
Referring to fig. 5 and 6, fig. 5 is a front view illustrating a seat post 210 of a seat post anti-theft structure according to a second embodiment of the utility model, and fig. 6 is a front exploded view illustrating the seat post 210 of the second embodiment of fig. 5. The seat post anti-theft structure (not shown in fig. 5 and 6) of the second embodiment is similar to the seat post anti-theft structure 100 of the first embodiment shown in fig. 1 to 4, except that the seat post 210 includes a lower tube 212, an upper tube 211 and a tail plug 215, the tail plug 215 is assembled at the tail end of the lower tube 212, and the limiting groove 213 is located in the tail plug 215. In other words, the second embodiment is not a lathe for forming the limiting groove 213 on the lower pipe 212, but the seat post 210 can also include the limiting groove 213 by combining the tail plug 215 with the limiting groove 213 on the lower pipe 212, which is more suitable for the lower pipe 212 with a thinner pipe wall.
Referring to FIG. 7, a bicycle 300 is illustrated in FIG. 7 in accordance with a third embodiment of the present invention. The bicycle 300 includes a frame (not shown), two wheels (not shown), and a seat post anti-theft structure 310, where the frame includes a middle tube 320, the middle tube 320 includes a hole (not shown), the two wheels are disposed on the frame, and the structure of the seat post anti-theft structure 310 is the same as the seat post anti-theft structure 100 of the first embodiment in fig. 1 to 4, and details are not repeated.
Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the utility model.
