Referring to fig. 1 to 3, fig. 1 is a schematic structural view of the connection between the connecting lock and the frame provided by the present invention; FIG. 2 is a cross-sectional view of the connector latch of FIG. 1; fig. 3 is an exploded view of the connecting shackle of fig. 1.

The utility model provides a connecting lock catch, the structure is as shown in figure 1 and figure 3, including connecting sleeve 1, connection piece 4 and stop gear. Wherein, the connecting sleeve 1 is sleeved on the periphery of the folding bicycle stand column through the connecting through hole and is fixedly connected with the folding bicycle stand column. The lateral wall of connecting sleeve 1 is equipped with inserting groove and mounting groove 12, and the notch of inserting groove is interface 11. The mounting groove 12 is located at one side of the insertion groove with a predetermined interval therebetween. The connecting sheet 4 has a strip-shaped connecting hole, the cloth can be connected with the strip-shaped connecting hole, and the front part of the connecting sheet 4 can be inserted into the inserting groove through the inserting port 11. One side of the connecting piece 4 is provided with a limiting notch 41, and after the connecting piece 4 is inserted into the insertion groove, the limiting notch 41 faces to the direction of the mounting groove 12. The limiting mechanism is installed in the installation groove 12, a locking hole 13 is formed in the preset gap, the position of the locking hole 13 corresponds to the position of a limiting notch 41 of the connecting sheet 4 inserted into the insertion groove, and the limiting mechanism can penetrate through the locking hole 13 to be in clamping fit with the limiting notch 41 to lock the connecting sheet 4. Of course, the user can also set the limiting mechanism on the side wall of the insertion groove according to the requirement, and the limitation is not limited herein.

Optionally, the limiting mechanism comprises a locking piece 5 and a locking button 2. As shown in fig. 2, the notch of the mounting groove 12 on the sidewall where the insertion opening 11 is located is a mounting opening, the locking piece 5 is mounted in the locking hole 13, the front portion of the latch button 2 is mounted in the mounting groove 12, and the button portion of the latch button 2 is located outside the mounting opening. The locking sheet 5 is connected with the locking button 2, and the plug-in connector of the locking sheet 5 penetrates through the locking hole 13 and is inserted into the limiting notch 41, so that the connecting sheet 4 is locked. The push button part is pushed to enable the plug connector to leave the limiting notch 41, and the connecting sheet 4 is unlocked.

Optionally, as shown in fig. 3, a part of the locking piece 5 located in the mounting groove 12 is provided with a limit groove perpendicular to the plug. One side of the locking button 2 close to the insertion groove is provided with a connecting groove, and the shape of the connecting groove is the same as that of the part of the locking piece 5 positioned in the mounting groove 12. Therefore have in the connecting groove with spacing groove complex stopper 22, the tip that connecting piece 4 was kept away from to stay 5 can imbed in the connecting groove, stopper 22 imbeds in the spacing groove simultaneously. The lock catch button 2 can apply acting force to the locking sheet 5 in the direction away from the connecting sheet 4 through the limiting block 22, so that the connecting sheet 4 is unlocked.

Furthermore, a guide block is arranged on one side of the mounting port close to the inserting port 11, and the guide block extends along the straight line parallel to the locking hole 13 to the direction far away from the inserting groove. Hasp button 2 has guide way 21, and the guide block inserts in the guide way 21, can carry out spacingly to hasp button 2, places hasp button 2 and drops from mounting groove 12. Meanwhile, the guide groove 21 may limit the moving direction of the locker button 2 so that the locker button 2 can only push the locking plate 5 for locking and unlocking operations.

Optionally, the mounting groove 12 is located below the insertion groove, and the mounting groove 12 further penetrates through the lower end surface of the connection sleeve 1. Thus, the side of the mounting groove 12 remote from the socket 11 is provided with the mounting groove cover 3. The mounting groove cover 3 is positioned below the lock button 2, and a return spring 6 is arranged between the mounting groove cover 3 and the lock button 2. The reset spring 6 is always in a compressed state, the spring force pushes the latch button 2 upwards, and then the latch button 2 applies an upward pushing force to the locking piece 5, so that the locking piece 5 is inserted into the locking hole 13. The plug extends into the plug groove through the locking hole 13. When the connecting piece 4 is inserted into the inserting groove, the inserting head is pushed back to the locking hole 13, when the limiting notch 41 moves to the position opposite to the locking hole 13, the inserting head is inserted into the limiting notch 41 under the pushing of the return spring 6, and the connecting piece 4 is locked. When the locking button 2 needs to be unlocked, the plug connector is enabled to leave the limiting notch 41 by pushing the locking button downwards, and then the connecting piece 4 is unlocked.

Alternatively, the side of the latch button 2 facing the mounting slot cover 3 is provided with a mounting hole 23, and the return spring 6 is inserted into the mounting hole 23. As shown in fig. 2, one end of the return spring 6 abuts against the mounting groove cover 3, and the other end abuts against the bottom of the mounting hole 23. The mounting hole 23 can limit the return spring 6 in the radial direction, so that the return spring 6 is prevented from being stuck.

Furthermore, when the connecting piece 4 is inserted into the inserting groove, in order to ensure that the inserting head can smoothly return to the locking hole 13, a guiding slope is arranged on one side of the front end of the inserting head close to the inserting port 11, and a chamfer structure matched with the guiding slope is arranged at the front end of the connecting piece 4. When the connecting piece 4 is inserted into the inserting groove, the chamfering structure is attached to the guide slope, and the thrust applied to the guide slope by the chamfering structure has component force parallel to the locking hole 13, so that the inserting head can be ensured to smoothly return to the locking hole 13. In addition, the bottom of the inserting groove is also provided with a fool-proof slope matched with the chamfering structure. When the limit notch 41 of the connecting piece 4 faces the locking hole 13, the connecting piece 4 can be smoothly inserted into the bottom of the insertion groove, otherwise, the connecting piece 4 cannot be inserted into the bottom of the insertion groove.

In this embodiment, the reset spring 6 pushes the locking piece 5 to be in insertion fit with the limiting notch 41 on the connecting piece 4 through the locking button 2, so as to lock the connecting piece 4. The user needs to push the locking button 2 and pull the connecting sheet 4 outwards to separate the cloth from the frame of the folding bicycle. The connecting lock catch reduces the risk of dismantling the cloth by misoperation of children, further reduces the possibility of damaging the children after dismantling the cloth, and improves the safety of the folding bicycle.
