[0021] See also Figure 1-5 The present invention provides a joint locking mechanism for a baby stroller, including a push rod connector 1, a push rod inner groove 2 is provided inside the push rod connector 1, a connecting column 3 is fixedly connected to the inside of the push rod inner groove 2, a push rod handle 4 is fixedly connected to the side surface of the push rod connector 1, a traction groove 5 is provided inside the push rod handle 4, the traction groove 5 passes through the push rod inner groove 2, one side of the push rod connector 1 is rotatably connected to the rear wheel bracket connector 14, one side of the rear wheel bracket connector 14 is rotatably connected to the front wheel bracket connector 16, and a double-headed lock tooth 19 is sleeved on the side surface of the connecting column 3.
[0022] Specifically, such as Figure 2 and Figure 5 As shown, a traction wire transition piece 6 is sleeved on the side surface of the connecting column 3 and located on one side of the double-headed lock tooth 19, a tightening block 7 is fixedly connected to one side of the traction wire transition piece 6, a connecting groove 8 is provided on the inner wall of the traction wire transition piece 6, a circular hole groove 9 is provided inside the traction wire transition piece 6, a coil spring 10 is provided on the inner wall of the circular hole groove 9, a ball 11 is rotatably connected to one side of the circular hole groove 9, a storage groove 12 is provided on the side surface of the traction wire transition piece 6, and a traction wire 13 is rotatably connected inside the storage groove 12.
[0023] Specifically, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the rear wheel support connector 14 is engaged with the push rod connector 1 , and a rear wheel inner groove 15 is defined inside the rear wheel support connector 14 .
[0024] Specifically, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the front wheel support connector 16 is snap-fitted with the rear wheel support connector 14 , a front wheel inner groove 17 is defined inside the front wheel support connector 16 , and a second connecting column 18 is fixedly connected inside the front wheel inner groove 17 .
[0025] Specifically, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the connecting column 1 3 is movably connected to the connecting column 2 18 , the side surface of the connecting column 1 3 is sleeved with a double-headed locking tooth 19 , and the side surface of the double-headed locking tooth 19 is fixedly connected with a protruding block 20 .
[0026] Specifically, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the connecting groove 8 is engaged with the protruding block 20, and the double-headed locking tooth 19 can move on the side surfaces of the connecting column 1 3 and the connecting column 2 18. The working principle and use process of the utility model are as follows: when using this device, the staff first holds the traction wire 13 and pulls the traction wire transition piece 6 to a certain angle, so that the connecting groove 8 drives the engaged protruding block 20 to rotate, and the protruding block 20 is set on the side surface of the double-headed locking tooth 19, which will cause the side surface of the double-headed locking tooth 19 to move along the side surface of the connecting column 1 3 and the connecting column 2 18, so that the double-headed locking tooth 19 is engaged with the push rod inner groove 2, the rear wheel inner groove 15 and the front wheel inner groove 17, thus completing the connection between the push rod connector 1, the rear wheel bracket connector 14 and the front wheel bracket connector 16. In addition, when the traction wire 13 is pulled, the traction wire 13 can be recovered and attached to the storage groove 12 due to the rebound force of the coil spring 10. As mentioned above, when it is necessary to separate the push rod connector 1, the rear wheel bracket connector 14 and the front wheel bracket connector 16, the staff can keep pulling the traction wire 13 to separate the double-headed lock tooth 19 with the protruding block 20 from the connecting groove 8. When the protruding block 20 is no longer engaged with the connecting groove 8, the lock between the push rod connector 1, the rear wheel bracket connector 14 and the front wheel bracket connector 16 can be released.
[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
