[0048] like Figures 1 to 11 As shown, the utility model provides a folding frame, which includes a shell base 1, a handlebar assembly 2, a front support leg 4 and a rear support leg 5. The shell base 1 has a clamping ring portion 11 relative to each other. The handlebar assembly 2 includes a handlebar seat 21 and a handlebar 22. The handlebar seat 21 is rotatably clamped between the two clamping ring portions 11. A slideway 23 is arranged in the handlebar seat 21. The first end of the slideway 23 passes through the handlebar seat 21. A first locking assembly 3 is arranged in the slideway 23. The handlebar 22 is slidably inserted into the slideway 23 by the first end of the slideway 23 so as to be able to move toward or away from the first locking assembly 3. The leg 4 is fixedly arranged on the shell base 1; the first end of the rear leg 5 is hinged to the clamping ring portion 11, and the second locking assembly 6 is arranged on the rear leg 5; the first locking assembly 3 and the second locking assembly 6 have a locked state and an unlocked state. When in the locked state, the rear leg 5 and the handlebar assembly 2 are both locked relative to the shell base 1, and when in the unlocked state, the rear leg 5 and the handlebar assembly 2 can both rotate relative to the shell base 1 to make the handlebar 22 and the rear leg 5 close to the front leg 4; when the handlebar 22 moves, the first locking assembly 3 and the second locking assembly 6 can switch between the locked state and the unlocked state.

[0049] By means of the first locking assembly 3 arranged in the slide 23 and the second locking assembly 6 arranged on the rear leg 5, and by means of the locking cooperation between the first locking assembly 3 and the second locking assembly 6, when the handlebar 22 is pushed to move in the direction of inserting into the slide 23, the first locking assembly 3 and the second locking assembly 6 can be unlocked, and then the handlebar 22 and the rear leg 5 can be rotated to make the handlebar assembly 2 and the rear leg 5 rotate relative to the shell seat 1, and since the front leg 4 rotates relative to the shell seat 1, the handlebar 22 and the rear leg 5 can be brought close to the front leg 4, thereby making the folding method easier; and when the handlebar 22 moves in the opposite direction, it can be locked again.

[0050] like Figures 1 to 4 As shown, in some embodiments, the housing 1 includes a housing and a clamping ring 11 disposed at intervals on the housing, and the clamping ring 11 is integrally formed with the housing. A mounting opening is provided on the side of the housing 1 away from the clamping ring 11, and the front leg 4 is fixedly inserted into the mounting opening. In some embodiments, the handlebar seat 21 is rotatably clamped between the two clamping rings 11, and the rear leg 5 is rotatably disposed on the other side of the clamping ring 11 away from the handlebar seat 21 to avoid interference between the two when they rotate.

[0051] like Figure 3 and Figure 5 As shown, in some embodiments, the first locking assembly 3 includes a first locking member 31 and a first elastic member 32. The first locking member 31 is slidably disposed in the slideway 23. The two ends of the first elastic member 32 respectively abut against the first end of the first locking member 31 and the second end of the slideway 23, and the handlebar 22 abuts against the second end of the first locking member 31. Correspondingly, as shown in FIG. Figures 6 to 9As shown, a mounting groove is provided at the first end of the rear support leg 5, and the groove opening of the mounting groove is connected to the annular opening of the clamping ring portion 11. The second locking member 61 includes a second elastic member 62 and a second locking member 61. The second locking member 61 slides in the mounting groove, and the sliding direction of the second locking member 61 is perpendicular to the moving direction of the first locking member 31. The second elastic member 62 abuts between the side of the second locking member 61 away from the first locking member 31 and the groove wall of the mounting groove. The second locking member 61 can penetrate the handlebar seat 21 and be plugged into the first locking member 31. Specifically, the first locking member 31 is a sliding block, and two first plug-in interfaces 33 are arranged at intervals on the sliding block. The spacing direction of the two first plug-in interfaces 33 is the same as the moving direction of the first locking member 31. The second locking member 61 includes an abutment plate 611 and an insertion block 612. The insertion block 612 is arranged on the abutment plate 611, and the insertion block 612 can be plugged in with the first plug-in interface 33. The abutment plate 611 slides in the above-mentioned mounting groove; an inclined surface 613 is provided on the insertion block 612, and the inner wall of the first plug-in interface 33 is provided with a guide surface that cooperates with the inclined surface 613. When the first locking member 31 moves to abut against the inclined surface 613, the inclined surface 613 is pushed to move along the guide surface, thereby causing the second locking member 61 to move in a direction away from the first locking member 31. That is, when the plug block 612 is located in the first plug port 33, the plug block 612 and the first locking member 31 restrict the rotation of the handlebar assembly 2 and the rear leg 5, and the handlebar assembly 2 and the rear leg 5 are in a locked state; and when the handlebar 22 moves into the slide 23, the handlebar 22 can abut against the above-mentioned first locking member 31, so that the first locking member 31 moves toward the first elastic member 32 and squeezes the first elastic member 32; at this time, due to the movement of the first locking member 31, the first locking member 31 abuts against the inclined surface 613 on the plug block 612, and due to the existence of the inclined surface 613, the plug block 612 moves in a direction away from the first locking member 31, and during the movement of the first locking member 31, it disengages from the above-mentioned first plug port 33 and is embedded in the handlebar seat 21, and at this time, the first locking member 31 and the second locking member 61 are in an unlocked state. After that, by continuing to rotate the rear leg 5, the rear leg 5 and the handlebar seat 21 rotate relative to each other, and the handlebar seat 21 can abut against the inclined surface 613 on the second locking member 61, so that the second locking member 61 continues to be pushed to squeeze the second elastic member 62 during the rotation process, so that the rear leg 5 can be folded, and then the handlebar 22 can be rotated to fold; thus, the handlebar assembly 2 and the rear leg 5 can be rotated and folded. The first elastic member 32 and the second elastic member 62 can make the first locking member 31 and the second locking member 61 keep the original position, that is, when the handlebar assembly 2 moves in the direction away from the first locking member 31, the first elastic member 32 can push the first elastic member 32 back, so that the first plug port 33 moves to the original position, and when the rear leg 5 is rotated to the original position, the plug block 612 can be re-aligned with the first plug port 33, and the second elastic member 62 prompts the plug block 612 to be inserted into the first plug port 33 to achieve re-locking.Exemplarily, the first elastic member 32 and the second elastic member 62 may be, but are not limited to, compression springs. Since the handlebar 22 is generally in an inclined state when in use, in the current embodiment, the slideway 23 is an inclined slideway 23, and the height of the first end of the slideway 23 is higher than the height of the second end of the slideway 23.

[0052] like Figure 7 As shown, in some embodiments, in order to further limit the relative rotation between the rear leg 5 and the handlebar seat 21 when locked, a plurality of spaced first protrusions 25 are provided on the side of the handlebar seat 21 facing the rear leg 5, and a plurality of spaced second protrusions 63 are provided on the outer edge of the second locking member 61. The present embodiment specifically refers to a plurality of spaced second protrusions 63 provided on the outer edge of the abutment plate 611. When the plug block 612 is plugged into the first plug interface 33, each first protrusion 25 is embedded between two adjacent second protrusions 63, thereby limiting the relative rotation between the two. When the first locking member 31 moves to drive the plug block 612 to disengage from the first plug interface 33, the first protrusion 25 disengages from between the two adjacent second protrusions 63, and the two can rotate relative to each other.

[0053] like Figure 3 As shown, in order to enable smooth rotation, the folding frame further includes a rotating shaft 7, which passes through the handlebar seat 21 and the clamping ring portion 11, and the two ends of the rotating shaft 7 are rotatably arranged on the rear support leg 5. Further, the rotating shaft 7 is plugged into the first locking member 31, and in order to prevent the rotating shaft 7 from interfering with the movement of the first locking member 31, the first locking member 31 is provided with a long hole 34, and the extending direction of the long hole 34 is the same as the moving direction of the first locking member 31, the rotating shaft 7 is plugged into the long hole 34, and the first plug interface 33 is located on both sides of the long hole 34.

[0054] like Figure 2 As shown, in some embodiments, when the handlebar 22 abuts against the first locking member 31, the first locking member 31 abuts against the first elastic member 32. In order to prevent the first elastic member 32 from pushing the first locking member 31 back to its original position when it is not expected, the handlebar assembly 2 further includes a handlebar sliding tube 24. The handlebar sliding tube 24 is plugged into the first end of the slideway 23. The handlebar 22 is slidably connected in the handlebar sliding tube 24. The handlebar sliding tube 24 can be interlocked with the handlebar 22. When the handlebar 22 slides to a specified position, it can be locked with the handlebar sliding tube 24, so that the handlebar 22 maintains a tendency to continuously abut against the first locking member 31 and avoids retreat. Specifically, the handlebar sliding tube 24 is provided with through holes spaced apart along its length direction, and the handlebar 22 is provided with an elastic pin, so that the handlebar 22 and the handlebar sliding tube 24 are locked by plugging the elastic pin into the through hole.

[0055] like Figure 3As shown, in some embodiments, the folding frame further includes a seat pan 8, which is connected to the shell seat 1, and a protruding plug-in protrusion 81 is provided on the seat pan 8, and the plug-in protrusion 81 is located between the two clamping rings 11. The handlebar seat 21 is provided with a second plug-in interface 26, and the plug-in protrusion 81 can be plugged into the second plug-in interface 26 for limiting, that is, at this time, the seat pan 8 cannot rotate relative to the shell seat 1; when the handlebar 22 rotates toward the shell seat 1, the plug-in protrusion 81 can be disengaged from the second plug-in interface 26, that is, at this time, the seat pan 8 can rotate relative to the shell seat 1, thereby realizing the folding of the seat pan 8. Specifically, the handlebar seat 21 is provided with an avoidance groove 27 to provide an installation position for the plug-in protrusion 81, and the second plug-in interface 26 is opened on the groove wall of the avoidance groove 27. Furthermore, the lower side surface of the plug-in protrusion 81 is an arc surface, so that when the handlebar 22 rotates in the direction close to the front leg 4, the groove wall of the avoidance groove 27 abuts against the arc surface of the plug-in protrusion 81, so that it can slide along the arc surface and abut the plug-in protrusion 81 in the process, so that it can smoothly disengage from the above-mentioned second plug-in interface 26 and release the limit; in addition, in the process of returning to the original position, the arc surface setting of the plug-in protrusion 81 can also enable the plug-in protrusion 81 to slide smoothly into the second plug-in interface 26.

[0056] The utility model also provides a cart, which includes wheels and the above-mentioned folding frame, and the front legs 4 and the rear legs 5 are correspondingly provided with wheels, so that the handlebars 22 can be pushed to achieve more convenient folding.

[0057] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
