Description

Technical Field

[0001] This utility model relates to the field of baby playpen technology, and in particular to a folding playpen frame. Background Technology

[0002] In the prior art, hexagonal folding play beds are typically composed of multiple X-shaped supports connected together. These X-shaped supports are usually movable, unfolding into an X-shape and folding into a straight line. To secure the folding play bed in its unfolded state, the prior art typically uses ropes to fix the two hinge points of adjacent X-shaped supports. However, this fixing method requires multiple points of connection to bind the ropes, which is cumbersome, and the ropes have a certain amount of slack, resulting in instability after fixing, as shown in patent document CN105491913A. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this utility model is to provide a folding play bed frame.

[0004] This utility model is implemented using the following method: a foldable play bed frame, including foldable X-shaped brackets and joint hinges, multiple X-shaped brackets are connected in sequence, and joint hinges are respectively connected to the top and bottom of two adjacent X-shaped brackets. A first locking mechanism is hinged between the top of the head end of the head X-shaped bracket and the top of the tail end of the tail X-shaped bracket, and a first locking mechanism is hinged between the bottom of the head end of the head X-shaped bracket and the bottom of the tail end of the tail X-shaped bracket, for unfolding and fixing the X-shaped brackets.

[0005] Preferably, the first locking mechanism includes a hinge and a locking member disposed in the hinge. The hinge connects the head end of the X-shaped bracket at the head and the tail end of the X-shaped bracket at the tail. The locking member is used to lock the X-shaped bracket after it is unfolded.

[0006] Preferably, the first locking mechanism further includes an unlocking component, which is disposed on the locking component for unlocking the locking component.

[0007] Preferably, the hinge includes a first connecting tube and a second connecting tube, the first connecting tube and the second connecting tube are hinged to each other, and the locking member and the unlocking member are installed at the hinge of the first connecting tube and the second connecting tube; the ends of the first connecting tube and the second connecting tube away from the hinge are respectively hinged to the corresponding X-shaped bracket.

[0008] Preferably, the locking element includes a locking block and a resetting element. The first connecting pipe has a first groove at the hinge, and the second connecting pipe has a second groove at the hinge opposite to the first groove. The locking block is movably installed in the first groove and the second groove. The resetting element is disposed between the locking block and the end face of the first groove or the end face of the second groove. The unlocking element is connected to the end face of the locking block opposite to the end face of the resetting element. The unlocking element and the resetting element have opposite driving directions and are used to drive the locking block to move between the first groove and the second groove. When the locking block is simultaneously located in the first groove and the second groove, the first connecting pipe and the second connecting pipe cannot rotate relative to each other.

[0009] Preferably, the unlocking element is a button, movably mounted on the second connecting pipe or the first connecting pipe at a position opposite to the locking block. The second connecting pipe or the first connecting pipe has a clearance hole to facilitate the button's insertion into and contact with the locking block. A first limiting groove is formed on the side wall of the first groove, and a second limiting groove is formed on the side wall of the second groove. The first limiting groove and the second limiting groove are directly opposite each other. A limiting protrusion is formed on the circumferential surface of the locking block, and the limiting protrusion can engage with the first limiting groove and the second limiting groove. Alternatively, the first groove and the second groove are polygonal or elliptical, and the corresponding locking block is also polygonal or elliptical.

[0010] Preferably, the X-shaped bracket is provided with joint hinges between itself and both the first connecting tube and the second connecting tube.

[0011] Preferably, a second locking mechanism is connected between the two scissor tubes of at least one of the X-shaped brackets.

[0012] Preferably, the second locking mechanism includes a first link, a second link, and a third link, with both ends of the third link hinged to one end of the first link and one end of the second link, and the other ends of the first link and the second link respectively connected to the two scissor tubes of the X-shaped bracket.

[0013] The beneficial effects of this utility model are as follows: This utility model provides a folding play bed frame, which, compared with the prior art, has at least the following technical effects: 1. By replacing the traditional multi-rope binding with a first locking mechanism at both ends, only two locking points are needed to complete the overall frame fixation, significantly reducing the operation steps; Enhanced stability: The double locking at the top and bottom forms a rigid support structure, avoiding swaying or loosening caused by rope slack, and improving the overall stability in the unfolded state; Symmetrical force design: The upper and lower locking mechanisms are symmetrically distributed, making the frame evenly stressed and preventing deformation or failure caused by stress concentration on one side. 2. The first locking mechanism includes a hinge and a locking component. The locking component is used to lock after unfolding, ensuring no accidental retraction after unfolding and improving the safety factor. 3. The unlocking component allows the play bed frame to be folded by unlocking the locking component and releasing the rigid support when it needs to be stored. 4. The locking block is simultaneously embedded in the grooves on both sides, forming physical interference and completely blocking the relative rotation of the connecting tubes. The locking strength far exceeds that of friction-dependent designs. Automatic reset function: The reset element (such as a spring) ensures that the locking block is in the locked position under normal conditions, preventing accidental unlocking due to vibration. 5. Button unlocking conforms to the user's intuitive operation habits, reducing the learning cost. 6. Limiting structures matching the locking block are set in the first and second grooves to prevent mutual rotation between the two, thus achieving locking after the game bed frame is unfolded. 7. The first and second connecting tubes are precisely matched with the X-shaped bracket through the joint hinge to ensure smooth folding / unfolding process and reduce jamming or abnormal noise. 8. A second locking mechanism is added to the X-shaped bracket to resist the force exerted by the first locking mechanism on the X-shaped bracket during folding. The two work together to ensure the stability of the X-shaped bracket after unfolding. 9. The second locking mechanism consists of a first link, a second link, and a third link. The three links form a straight line, which can form a stable triangular structure with the two scissor tubes of the X-shaped bracket. It works in conjunction with the first locking mechanism to ensure the stability of the game bed frame after it is unfolded and to prevent accidental folding. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] Please see Figures 1 to 5 A folding play bed frame includes foldable X-shaped supports 1 and joint hinges 2. Multiple X-shaped supports 1 are connected sequentially. The top and bottom of adjacent X-shaped supports 1 are connected to joint hinges 2. A first locking mechanism 3 is hinged between the top of the head end of the head X-shaped support 1 and the top of the tail end of the tail X-shaped support 1, and also between the bottom of the head end of the head X-shaped support 1 and the tail end of the tail X-shaped support 1, for unfolding and fixing the X-shaped supports. The first locking mechanism 3 at both ends replaces the traditional multi-rope binding, requiring only two locking points to fix the entire frame, significantly reducing operation steps; enhanced stability: the double locking at the top and bottom forms a rigid support structure, preventing swaying or loosening due to rope slack, improving the overall stability in the unfolded state; symmetrical force distribution design: the upper and lower locking mechanisms are symmetrically distributed, ensuring even force distribution on the frame and preventing deformation or failure caused by stress concentration on one side. Preferably, five X-shaped brackets can be connected in sequence, or seven X-shaped brackets can be connected in sequence to form a hexagonal or octagonal play bed frame, but this is not a limitation.

[0022] Please see Figures 1 to 5 Preferably, the first locking mechanism 3 includes a hinge and a locking member disposed in the hinge. The hinge connects the head end of the X-shaped bracket 1 at the head and the tail end of the X-shaped bracket 1 at the tail. The locking member is used to lock the X-shaped bracket after it is deployed. The first locking mechanism 3 includes a hinge and a locking member. The locking member is used to lock after deployment to ensure that there is no accidental retraction after deployment, thereby improving the safety factor.

[0023] Please see Figures 1 to 5Preferably, the first locking mechanism 3 further includes an unlocking component 35, which is disposed on the locking component for unlocking the locking component. The unlocking component 35 allows the game bed frame to be folded by unlocking the locking component and releasing the rigid support when it is necessary to store the game bed frame.

[0024] Please see Figures 1 to 5 Preferably, the hinge includes a first connecting pipe 31 and a second connecting pipe 32, which are hinged together. The locking element and the unlocking element 35 are installed at the hinge joint of the first connecting pipe 31 and the second connecting pipe 32. The ends of the first connecting pipe 31 and the second connecting pipe 32 away from the hinge joint are respectively hinged to the corresponding X-shaped bracket 1. This facilitates connection with the X-shaped bracket 1.

[0025] Please see Figures 1 to 5 Preferably, the locking element includes a locking block 33 and a reset element 34. The first connecting pipe 31 has a first groove at its hinge, and the second connecting pipe 32 has a second groove at its hinge opposite to the first groove. The locking block 33 is movably installed in the first groove and the second groove. The reset element 34 is disposed between the locking block 33 and the end face of the first groove or the end face of the second groove. The unlocking element 35 is connected to the end face of the locking block 33 opposite to the end face of the reset element 34. The unlocking element 35 and the reset element 34 have opposite driving directions, which drives the locking block 33 to move between the first groove and the second groove. When the locking block is simultaneously located in the first groove and the second groove, the first connecting pipe 31 and the second connecting pipe 32 cannot rotate relative to each other. The locking block 33 is simultaneously embedded in the grooves on both sides to form physical interference, completely blocking the relative rotation of the connecting pipes. The locking strength far exceeds that of friction-dependent designs. Automatic reset function: The reset element 34 (such as a spring) ensures that the locking block 33 is in the locked position under normal conditions, preventing accidental unlocking due to vibration.

[0026] Please see Figures 1 to 5 Preferably, the unlocking component 35 is a button, movably mounted on the second connecting pipe 32 or the first connecting pipe 31 at a position opposite to the locking block 33. The second connecting pipe 32 or the first connecting pipe 31 has clearance holes to facilitate the button's insertion into and contact with the locking block 33. Button-type unlocking conforms to the user's intuitive operating habits and reduces the learning curve. More preferably, the clearance holes are two symmetrically arranged around the hinge axis. The two prongs 351 of the button are respectively inserted into the corresponding clearance holes, and the prongs 351 contact the end face of the locking block 33, which can both prevent the button from disengaging and also serve as a limiting and anti-rotation function.

[0027] Please see Figures 1 to 5The first groove has a first limiting groove 311 on its sidewall, and the second groove has a second limiting groove 321 on its sidewall. The first limiting groove 311 and the second limiting groove 321 are directly opposite each other. The locking block 33 has a limiting protrusion 331 on its circumferential surface, which can engage with the first limiting groove 311 and the second limiting groove 321. Alternatively, the first groove and the second groove are polygonal or elliptical, and the locking block 33 is also polygonal or elliptical. Limiting structures matching the locking block 33 are provided in the first and second grooves to prevent them from rotating relative to each other, thus achieving locking after the game bed frame is unfolded.

[0028] Please see Figures 1 to 2 Preferably, the X-shaped bracket 1 is provided with joint hinges 2 between itself and both the first connecting tube 31 and the second connecting tube 32. The precise cooperation between the first connecting tube 31 and the second connecting tube 32 and the X-shaped bracket 1 via the joint hinges 2 ensures a smooth folding / unfolding process and reduces jamming or abnormal noise.

[0029] Please see Figures 1 to 2 Preferably, at least one of the X-shaped brackets 1 has a second locking mechanism 4 connected between the two scissor tubes. The addition of the second locking mechanism 4 to the X-shaped bracket 1 is used to resist the folding force exerted by the first locking mechanism 3 on the X-shaped bracket 1, and the two work together to ensure that the X-shaped bracket 1 remains stable after unfolding.

[0030] Please see Figures 1 to 2 Preferably, the second locking mechanism 4 includes a first connecting rod 41, a second connecting rod 42, and a third connecting rod 43. The two ends of the third connecting rod 43 are hinged to one end of the first connecting rod 41 and one end of the second connecting rod 42, respectively. The other ends of the first connecting rod 41 and the second connecting rod 42 are respectively connected to the two scissor tubes of the X-shaped bracket 1. The second locking mechanism 4, composed of the first connecting rod 41, the second connecting rod 42, and the third connecting rod 43, forms a straight line, creating a stable triangular structure with the two scissor tubes of the X-shaped bracket 1. This, in conjunction with the first locking mechanism 3, ensures the stability of the play bed frame after unfolding, preventing accidental folding. A limiting protrusion (not shown) is provided on the upper end face of the second connecting rod 42 to prevent the first connecting rod 41 and the third connecting rod 43 from rotating downwards relative to the second connecting rod 42. This ensures that when the three are in a straight line, they can be taut to prevent the X-shaped bracket 1 from folding, so that the play bed frame cannot be folded unless an external force is directly applied to the second connecting rod 42 (i.e., a person pushes the second connecting rod 42 upwards). Of course, the limiting protrusion can also be set on the lower end face, and the second link 42 is pushed down when unlocking is required.

[0031] The working principle of this utility model is as follows:

[0032] When the game frame needs to be unfolded, pull any two X-shaped brackets 1 with both hands to move them away from each other. The game frame will gradually unfold until the first link 41, the second link 42, and the third link 43 of the second locking mechanism 4 are unfolded to the horizontal position. The first connecting tube 31 and the second connecting tube 32 rotate to the horizontal position. At this time, the first groove and the second groove are in an angled state, that is, the first limiting groove 311 and the second limiting groove 321 are directly opposite each other. At this time, the locking block 33 can be driven by the reset member 34 to enter the second groove from the first groove, or enter the first limiting groove 311 from the second limiting groove 321. The locking block's limiting protrusion 331 engages with the first limiting groove 311 and the second limiting groove 321 at the same time. The first connecting tube 31 and the second connecting tube 32 can no longer rotate relative to each other, thereby locking the game frame in the unfolded state.

[0033] When the game frame needs to be folded, first press the button of one of the first locking mechanisms 3 to make the locking block 33 overcome the force of the reset member 34 and move away from the first groove or the second groove, so that the locking block 33 can only cooperate with the first limiting groove 311 or the second limiting groove. In this way, the first connecting tube 31 and the second connecting tube can rotate relative to each other. Then, push the hinge point of the two by hand so that the two are no longer in a horizontal state. The locking block 33 is limited by the end face of the first groove or the second groove and cannot be pushed into the first groove or the second groove. It can continue to rotate without pressing the button. Then press the button of the other first locking mechanism 3 to make it also in the unlocked state. Then push the second link 42 upward or downward by hand so that the first link 41, the second link 42 and the third link 43 are no longer in a horizontal state. Then push each X-shaped bracket 1 to fold it. At the hinge point of the first connecting tube 31 and the second connecting tube 32, push the second link 42 until the folding is completed.
