New description: [New technical field] [0001] This creation is about a new type of creation of a kind of folding and folding machine, especially a double locking function to 'Μ 疋A folding bicycle folding device for enhanced safety. [Prior Art] •• Just press,. Xi (4) stacked bicycles are often equipped with a folding table between the pipe fittings' to manipulate the folding between the official parts. The common folding device has the installation. • On the main frame (to facilitate folding the frame), the handlebar Compared with the front camp (to facilitate folding the handlebar down) or the seatpost (to facilitate folding the seat cushion down), it can be said that the structure and appearance of the folder are quite large. The folding device provided on the conventional folding bicycle is generally divided into left and right casings, and is pivotally connected by one rod on one side, so that the left and right casings are close together or the shaft is used as the axis. The heart is unfolded; a quick-release group is arranged on the side of the frame of the left and right casings, and the quick-release group can lock the left and right casings when the left and right casings are swinged, so that the left and right casings cannot be lightened by themselves. It is easy to disengage, so it is necessary to unlock the left and right casings by operating the quick release group to unlock the locking effect. Therefore, the folding device installed on the conventional folding bicycle is divided into the following two states in use: 1. When the left and right casings of the folding device are close together (regardless of whether the quick release group is locked or unlocked), the folder is erected. The second pipe is not folded. 2. When the left and right casings of the folder are unfolded, the quick-release group must be unlocked, and the two pipe fittings of the folder are folded. Folding device mounted on a conventional folding bicycle 'When the left and right casings are brought together, the left and right hub bodies of the folder are generated by operating the quick release group. 10120633# Single number A〇101 Page 3 / Total 29 pages 1012020962 -0 M434718 Locking effect, generally the locking effect generated by the quick-release group itself is called the first re-locking effect. Because the general quick release group has an operation handle, so as to facilitate the operation of the quick release group to generate a locking action or unlock the locking function, that is, whether the locking action or the unlocking action is to be performed, the operation handle is operated, In the actual use, the folder having only the first weight (single weight) locking function may have the advantage that the operation handle is easily displaced (unlocked) due to vibration or being inadvertently touched (or hit). In particular, the folding bicycle travels in the environment of frequent vibrations, so if the handle is suddenly unconsciously undisturbed and the lock of the folder is unlocked, the rider may be seriously catastrophic. Therefore, a folding bicycle folding device having a double locking function is produced, and as shown in the first figure, a folding bicycle folding device 1 having a double locking function is provided, which has a left casing 11 and a right casing 12. The left and right housings 11 and 12 are respectively connected to each other by a shaft, so that the left and right housings 11 and 12 can be closed or unfolded with the shaft as an axis. Acting; a quick-release group 13 is disposed on the non-twisting side of the left and right housings 11, 12, and the outside thereof obviously has an operating handle 131 for operating the internal components of the quick-release group 13; When the bodies 11 and 12 are close together, the operating handle 131 can be pulled toward the tubular member 121 to make the internal components of the quick release group 13 generate a first re-locking effect on the left and right housings 11 and 12; A card body 14 is fixed on the outside of the pipe member 121, and is formed of a material having stretch elasticity. The opening is retracted. When the handle 131 is close to the pipe member 121, the card body 14 is touched and pushed inwardly to make Positioning; therefore, the grip of the operating handle 131 is reached by the card body 14 Into the second locking effect. However, the missing is that the card body 14 is not weather-resistant, and its elasticity is dip suddenly after use, resulting in the second weight locking effect 10120633#单号A〇101 Page 4/29 pages 1012020962-0 M434718 fe scattered and not good . As shown in the second figure, there is another conventional folding bicycle folder 2 having a double locking function, which also has a left casing 21 and a right casing 22, respectively engaged with a pipe member 211 '221; left and right casings The bodies 21 and 22 are pivotally connected to each other by a shaft so that the left and right housings 21 and 22 can be brought together or the shaft is pivoted; the non-polar sides of the left and right housings 21 and 22 are Then, a quick release group 2 3 is provided, and the external operation of the quick release group 23 is operated by an operation handle 2 31; when the left and right housings 21 and 22 are brought together, the operation handle 231 is pulled toward the pipe member 221. The inner component of the quick release group 23 can be used to generate a first re-locking effect on the left and right housings 21 and 22, and the insertion handle 231 is provided with a socket 232, and the tube member 221 is adjacent to the socket 232. A positioning member 24 for deflecting the upper and lower sides of the plate is provided, mainly having a latching block 241 at the bottom thereof. Therefore, when the operating handle 231 is completely close to the tubular member 221, the positioning member 24 can be pulled toward the operating handle 231. Deflection, as shown in the third figure, causes the card block 2 41 to abut the jack 2 3 2 is positioned; because of this, the card block 2 41 achieves a second locking effect on the latch of the handle 231. The missing part is that the positioning member 24 is simply framed on the pipe member 221, so the use process is often subjected to vibration and is easy to loose, so that when the folding bicycle is operated to perform the folding action, the positioning member 24 must be taken care of. Falling down makes it extremely uncomfortable to operate the folding bike for folding. Moreover, when the positioning member 24 is loose, it may happen that the second locking operation is suddenly released due to the snapping of the latching block 241 by the latching block 241 of the positioning member 24 during the riding process, resulting in unpredictable Danger.

The 332 is driven to resist the thrust of the elastic member 323 and can be laterally moved within the notch 321 'that is, the holding of the operating handle 33 can drive the engaging block 332 to resist the gap 321 . The lateral movement of the elastic member 323 (not shown in the sixth figure) 'the distance that can be moved is c, and it must be mentioned that, in the state shown in the sixth figure, the threading shaft 322 does not resist the elastic member 323. The tip end has exited the range of the receiving pocket 324; then when the operation 10120633^^^^ A0101 8th/29 pages 1012020962-0 M434718 handle 33 is no longer held, due to the elastic force of the elastic member 323 Pushing action, such that the threading shaft 322 will drive the joint block 332 together with the operating handle 33 to move back to the end of the elastic member 323 (as shown in FIG. 5), and it must be mentioned that, in the fifth In the state shown in the figure, the threading shaft 322 does not resist the end of the elastic member 323 and re-enters the capacity. Within the range of the hole 324. When the folder 3 is fully deployed, as shown in the fourth and seventh figures, the tubes 316, 32 5 are in a folded state; then, when the tubes 3 6 and 325 are aligned (not folded), first As shown in the eighth and ninth figures, the first housing 31 is rotated toward the second housing 32 by the pivot 326. In the process, the second clamping rod 315 of the first housing 31 is rounded. The arcuate head 3151 will first enter the receiving hole 324 of the second housing 32, so the arcuate head 3151 will be received by the end of the second housing 32 without the elastic member 323. Blocked and can no longer fall, resulting in the close state shown in the ninth figure. Then, the user applies a slight force to press the first housing 31 downward, so that the arcuate head 3151 pushes the threading shaft 322 (along with the engaging block 332 and the operating handle 33) to resist the elastic force of the elastic member 3235. When the end of the elastic member 323 moves, the arc-shaped head 3151 descends to the lowest position, and the first and second housings 3, 32 are completely closed together, thereby forming the tenth and eleventh figures. The state of being close together. Then, the shaft 322 (along with the engaging block 332 and the operating handle 33) is momentarily pushed by the elastic force of the elastic member 323 so that the end of the elastic member 323 is not returned to the range of the receiving hole 324. Because the position is above the arc-shaped head 3151, it abuts against the plane of the non-circular end of the arc-shaped head 3151, so that the first and second housings 31 and 32 cannot be disengaged. The locking action of the threading shaft 322 against the plane of the non-arc end of the arcuate head 3151 is the second locking action of the folder 3 of the present embodiment. 1〇1面单单号显1 Page 9/Total 29 pages 1012020962-0 M434718 Next, the user can pull the operating handle 33 toward the first housing 31 as shown in the twelfth and thirteenth figures. Deflecting, the latching socket 331 is placed around the arcuate head 3141 of the latching lever 314, and then continues to drive the latching lever 314 to deflect and finally pass over a highest point to form the latching socket 331 The arcuate head 3141 of the card mast 314 is clamped, and the latching lever 314 is obliquely pressed downward against the locked state of the first housing 31, which is the folder 3 of the present embodiment. The first re-locking effect. When the user wants to fold the two tubular members 316, 325, the locked state of the folding device 3 must first be unlocked. First, the user must pull the operating handle 33 outward and downward to cause the locking socket 331 to drive the handle. The latching lever 314 is deflected outwardly. After the latching socket 331 drives the arcuate head 3141 over a highest point, the operating handle 33 is disengaged from the latching lever 314 (recovering the tenth, eleventh In the state shown in the figure, the first re-locking action is disengaged; then the user must hold the operating handle 33 by hand to drive the engaging block 332 in the notch 321 to resist the lateral thrust of the elastic member 323. Moving (moving in the distance c as shown in the sixth figure), the threading shaft 322 does not abut against the end of the elastic member 323 and exits the receiving pocket 324, thus unlocking the second re-locking effect; The two tubular members 316 and 325 can be folded in the same manner, and the first and second housings 31 and 32 are unfolded by the action of folding the tubular members 316 and 325 (recovering the fourth and seventh figures) State). The folder 3 of the present invention is installed on the folding bicycle and is not restricted. Except that it can be mounted on the main frame (as described above, the frame is folded), it can also be installed in Between the handlebar and the front fork tube, the handlebar is folded downward, and as shown in FIG. 14, the folder 3 is mounted between the handlebar 41 and the front fork tube 42, so the same as the foregoing Operation Hand Li 063: #单编号 A0101 Page 10 / Total 29 pages 1012020962-0 M434718 Segments and steps 'can be folded by the action of the folder 3 to fold the handlebar 41 and the other official 42' and by The action of folding the folder 3 together aligns the handle bar 41 with the front tube 42 (not folded). Therefore, under the same structural composition and the same technical principle, the folder 3 of the present invention can of course be mounted on the seatpost, and the folding operation of the seat cushion can be achieved through the same operation means and steps. More details. It can be seen from the above description that the present invention provides a folding bicycle folding device 3 with double locking function, mainly in that the first and second housings 31 and 32 of the folder 3 are pressed against the arc-shaped rod by the threading shaft 322. The second re-locking action of the folder 3 can be achieved on the non-arc end of the head 3151, and the pulling operation handle 33 is deflected upward, and the arc-shaped rod of the clamping rod 314 is driven by the locking socket 331 thereof. The first re-locking action formed by the head 3141 over a highest point causes the folder 3 to have a double locking effect; wherein the components that generate the second re-locking function are hidden inside the first and second housings 31, 32, It can't be seen from the outside, and it can't be directly touched. Therefore, the second locking device can be weather-resistant and shock-resistant. During the use of the folding bicycle, there is no need to worry about the second locking action to disengage itself; The first and double locking interactions have a multiplication effect, which makes the use of the folding bicycle more secure. In summary, the folding bicycle folding device with double locking function has the absolute novelty that has never been seen before, and it can fully meet the requirements of establishing patents because of the fact that it has improved performance. However, the above embodiments are only used to illustrate the composition and efficacy of this creation, and are not intended to limit the scope of the patents of this creation.
