Description

Technical Field

[0001] This application relates to the field of toy crib technology, and in particular to a toy crib that can be assembled and used in combination. Background Technology

[0002] Toy bumpers are an important product in the field of infant and toddler care. Their main function is to provide infants and toddlers with a safe and independent play and rest space, preventing them from climbing out or coming into contact with dangerous objects. In recent years, toy bumpers with a "dual-purpose" function have appeared on the market. This means that the product can not only be used as a standalone enclosure, but also be equipped with wheels and a pull rod to allow it to be pulled outwards, thus functioning as a "cart." This design enhances the functionality of the toy bumper.

[0003] However, switching between different functions of the toy bed requires installing / removing the casters and pull rods. If the connection between the casters and pull rods and the toy bed is complex, it reduces the ease of switching functions. Therefore, a toy bed design that allows for quick assembly and disassembly of the casters / pull rods is needed. Utility Model Content

[0004] To facilitate the assembly and disassembly of the rollers / pull rods and the toy bed, this application provides a toy bed that can be assembled and disassembled.

[0005] The toy-style bed that can be assembled and used in this application adopts the following technical solution:

[0006] A toy crib that can be assembled and disassembled includes a crib frame, rollers, pull rods, and connecting components. The connecting components are used to connect the rollers / pull rods to the crib frame. The connecting components include a mounting sleeve, a positioning rod, and a resetting component. The mounting sleeve is fitted onto the outer wall of the crib frame. The crib frame has a mounting groove, and the positioning rod is movably installed in the mounting groove. The resetting component is used to drive the positioning rod to move towards the side away from the mounting groove. The mounting sleeve has a positioning hole, and the end of the positioning rod away from the mounting groove passes through the positioning hole and is exposed to the outside.

[0007] By adopting the above technical solution, the first connecting component enables the connection between the roller and the bed frame, and the second connecting component enables the connection between the pull rod and the bed frame. The roller and bed frame are securely connected by the mounting sleeve fitted onto the outer wall of the bed frame and the positioning rod passing through the positioning hole. The reset component drives the positioning rod away from the mounting slot, ensuring the positioning rod remains inserted into the positioning hole and guaranteeing connection stability. This allows for quick installation of the roller and pull rod to the bed frame, improving the convenience of switching the toy bed frame's functions. Furthermore, when it is necessary to disconnect the roller from the bed frame, simply push the positioning rod back into the mounting slot.

[0008] Optionally, the end of the positioning rod away from the mounting groove is provided with a hemispherical head.

[0009] By adopting the above technical solution, when it is necessary to cancel the connection between the bed frame and the rollers, the hemispherical head is pushed back into the positioning hole; then the mounting sleeve is pulled to drive the mounting sleeve to disengage from the bed frame. At this time, the outer wall of the hemispherical head abuts against the inner wall of the positioning hole, and the positioning rod returns to the mounting groove under the guidance of the hemispherical head, thereby enabling the mounting sleeve to be unfixed to the bed frame.

[0010] Optionally, the rollers are provided in multiple sets, and all rollers are connected by a connecting frame; the connecting frame is provided with an unlocking component, which is used to drive all positioning rods to be disengaged from the positioning holes.

[0011] By adopting the above technical solution and setting up a connecting frame and unlocking components, it is possible to simultaneously cancel the connection between all rollers and the bed frame, and remove them from the bed frame at the same time, thereby improving unlocking efficiency.

[0012] Optionally, the unlocking component includes a gear and multiple racks. The gear is rotatably mounted on the connecting frame, and the racks are slidably mounted on the connecting frame and mesh with the gear. One end of the rack is provided with an unlocking plate, which is used to push the hemispherical head back into the positioning hole.

[0013] By adopting the above technical solution, rotating the gear causes all racks to slide on the connecting frame under the meshing of the gear, so that all unlocking plates move toward one side of each positioning rod, and all hemispherical heads enter into each positioning hole, thereby enabling all mounting sleeves to simultaneously disengage from the bed frame.

[0014] Optionally, the gear is provided with a rotating rod, and the rotating rod is fitted with a rubber sleeve.

[0015] By adopting the above technical solution, the gear is equipped with a rotating rod and a rubber sleeve, which increases the friction between the hand and the rotating rod, making it easier and more convenient for the operator to rotate the rotating rod.

[0016] Optionally, a torsion spring is provided between the gear and the connecting frame, and the elastic force of the torsion spring is used to drive the unlocking plate to move toward the side away from the hemispherical head.

[0017] By adopting the above technical solution, after driving all the hemispherical heads into the positioning holes, the connecting bracket is pulled to make the hemispherical heads enter the mounting slots; at this time, the force applied to the gear is released, and the gear returns to its original state under the elastic force of the torsion spring, so that it can be used next time.

[0018] Optionally, a limit block is provided at one end of the rack, and a limit groove is provided on the connecting frame for the limit block to slide; when the unlocking plate pushes the hemispherical head back into the positioning hole, the limit block abuts against one side of the limit groove.

[0019] By adopting the above technical solution, when the unlocking plate pushes the hemispherical head back into the positioning hole, the limiting block abuts against one end of the limiting groove, thus preventing the unlocking plate from entering the positioning hole.

[0020] Optionally, the bed frame is provided with guide blocks, and the inner wall of the mounting sleeve is provided with guide grooves for the guide blocks to be inserted.

[0021] By adopting the above technical solution, the cooperation between the guide block and the guide groove can play a guiding role, which can make the mounting sleeve more accurately and smoothly fitted onto the outer wall of the bed frame, facilitating the connection and installation of the rollers with the bed frame, thereby improving the convenience of roller installation in the modular toy bed.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By using the first connecting component, the mounting sleeve is fitted onto the outer wall of the bed frame, and the resetting component drives the positioning rod away from the mounting groove, which can keep the positioning rod inserted into the positioning hole and ensure connection stability. This allows for quick installation of the rollers and pull rods to the bed frame, improving the convenience of switching the toy bed frame function.

[0024] 2. By setting a limit block and a limit groove, when the unlocking plate pushes the hemispherical head back into the positioning hole, the limit block and one end of the limit groove abut against each other, preventing the unlocking plate from entering the positioning hole.

Detailed Implementation

[0032] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0033] Example 1:

[0034] This application discloses a toy-style bed that can be assembled and used in combination.

[0035] Reference Figure 1 A modular toy bed includes a bed frame 1, rollers 2, a pull rod 3, a first connecting component 4, and a second connecting component 5. The surface of the bed frame 1 is covered with fabric (not shown in the figure) to allow items to be placed inside the bed frame 1. The first connecting component 4 is used to connect the rollers 2 to the bed frame 1, and the second connecting component 5 is used to connect the pull rod 3 to the bed frame 1. This arrangement allows the rollers 2 and the pull rod 3 to be stably connected to the bed frame 1.

[0036] Reference Figure 2 The bed frame 1 is provided with legs 11, each leg 11 including a support part 12 and an assembly rod 13. The support part 12 is used to mount the bed frame 1 for connection with the rollers 2. The support part 12 has a circular cross-section and is hollow in the middle to reduce weight. The support part 12 has assembly slots 14 on both sides that are connected to it. The assembly rod 13 is inserted into the two assembly slots 14 of the support part 12, and the two ends of the assembly rod 13 are welded to the inner walls of the two assembly slots 14 respectively.

[0037] The rollers 2 are provided in multiple sets, and it can be understood that the first connecting component 4 is provided in multiple sets; the rollers 2 are provided with mounting sleeves 21, which are fitted onto the outer wall of the support part 12, and the first connecting component 4 is used to connect the mounting sleeves 21 to the support part 12; the shape of the mounting sleeves 21 is adapted to the shape of the support leg 11, and the mounting sleeves 21 are generally made of plastic or metal. Plastic is lightweight and low cost, while metal is more robust and durable.

[0038] The first connecting assembly 4 includes a positioning rod 41 and a resetting component 42. One end of the assembly rod 13 has a mounting groove 15, and the positioning rod 41 is movably installed within the mounting groove 15. The mounting sleeve 21 has a positioning hole 22, and the end of the positioning rod 41 furthest from the mounting hole protrudes through the positioning rod 41 and is exposed to the outside. The resetting component 42 is a spring, with both ends connected to the inner wall of the mounting groove 15 and the positioning rod 41, respectively. The spring force can drive the positioning rod 41 to move towards the side furthest from the mounting groove 15.

[0039] When the mounting sleeve 21 is fitted onto the bed frame 1, the end of the positioning rod 41 is inserted into the positioning hole 22 under the action of the spring, thereby fixing the mounting sleeve 21 and the bed frame 1 together, thus realizing the connection between the roller 2 and the bed frame 1.

[0040] A hemispherical head 43 is provided at the end of the positioning rod 41 away from the mounting hole. The hemispherical head 43 protrudes from the outer wall of the mounting sleeve 21 under the elastic force of a spring. When removing the roller 2 from the support 12, the hemispherical head 43 is pressed into the positioning hole 22. Then, the mounting sleeve 21 is removed from the support 12. Due to the design of the hemispherical head 43, the positioning rod 41 can be guided into the mounting groove 15, which improves the efficiency of disassembly and assembly. The hemispherical head 43 is generally made of metal or plastic. The metal hemispherical head 43 is more wear-resistant, while the plastic hemispherical head 43 is lighter.

[0041] In this embodiment, a guide block (not shown in the figure) is provided on the outer wall of the support part 12, and a guide groove is provided on the inner wall of the mounting sleeve 21 for the guide block to slide. The cooperation between the guide block and the guide groove makes it possible for the positioning hole 22 and the mounting groove 15 to be aligned, thereby further improving the assembly efficiency.

[0042] Reference Figure 3 The pull rod 3 is provided with a connecting sleeve 31, which is fitted onto the outer wall of the bed frame 1. The second connecting component 5 is used to fix the connecting sleeve 31 to the bed frame 1. Since the second connecting component 5 has the same structure as the first connecting component 4, it will not be described in detail here.

[0043] The implementation principle of Embodiment 1 of this application is as follows:

[0044] The first connecting component 4 can be used to connect the roller 2 to the bed frame 1, and the second connecting component 5 can be used to connect the pull rod 3 to the bed frame 1. By fitting the mounting sleeve 21 onto the outer wall of the bed frame 1 and inserting the positioning rod 41 through the positioning hole 22, the roller 2 and the bed frame 1 can be securely connected. The reset component 42 drives the positioning rod 41 away from the mounting groove 15, which can keep the positioning rod 41 inserted into the positioning hole 22 and ensure the stability of the connection. Thus, the installation of the roller 2 and the pull rod 3 to the bed frame 1 can be completed quickly, improving the convenience of the toy bed switching function.

[0045] Example 2:

[0046] This application discloses a toy-style bed that can be assembled and used in combination.

[0047] Reference Figure 4 The difference between Embodiment 2 and Embodiment 1 is that all the mounting sleeves 21 on the rollers 2 are connected by a connecting frame 6. The connecting frame 6 can be a metal frame or a plastic frame. In this application, the connecting frame is a plastic frame, which is lightweight and easy to assemble and disassemble. The connecting frame 6 is provided with an unlocking element 7, which is used to drive all the hemispherical heads 43 into their respective positioning holes 22. The unlocking element 7 allows the positioning rod 41 to simultaneously enter the mounting hole when the rollers 2 need to be disassembled, improving disassembly efficiency.

[0048] Reference Figure 5 The unlocking component 7 includes a gear 71 and multiple racks 72. The gear 71 is rotatably mounted in the middle of the connecting frame 6. In this embodiment, the gear 71 is rotatably mounted in the connecting frame 6 via a rotating shaft. A rotating rod 73 is provided on the side of the gear 71 away from the connecting frame 6. The rotating rod 73 is used to rotate the gear 71. The rotating rod 73 is provided with a rubber sleeve 74, which can increase the friction between people's hands and the rotating rod 73.

[0049] Reference Figure 5 and Figure 6 One end of the rack 72 is integrally formed with a connecting part 77, and a limiting block 76 is provided on one side of the connecting part 77. The connecting frame 6 has a limiting groove 61 for the limiting block 76 to slide. The sliding of the limiting block 76 and the limiting groove 61 allows the rack 72 to slide and be installed on the connecting frame 6, and the rack 72 meshes with the gear 71. The gear 71 and the rack 72 are usually made of plastic.

[0050] Reference Figure 6 An unlocking plate 75 is provided on one side of the connecting part 77. The unlocking plate 75 is used to push the hemispherical head 43 back into the positioning hole 22. When the gear 71 is rotated to move the rack 72, the unlocking plate 75 moves with the rack 72, pushing the hemispherical head 43 of the positioning rod 41 back into the positioning hole 22, thereby releasing the connection between the roller 2 and the bed frame 1. In this embodiment, when the unlocking plate 75 pushes the hemispherical head 43 back into the positioning hole 22, the limiting block 76 abuts against one end of the limiting groove 61 to prevent the unlocking plate 75 from entering the positioning hole 22.

[0051] In this embodiment, a torsion spring is provided on the rotating shaft, and the two ends of the torsion spring are connected to the gear 71 and the connecting frame 6 respectively; the torsion force is used to drive the unlocking plate 75 to move toward the side away from the hemispherical head 43. When the gear 71 is rotated to push the positioning rod 41 out of the positioning hole 22, the rotating rod 73 is released, and the torsion spring will cause the gear 71 to reverse, driving the unlocking plate 75 back to the initial position, waiting for the next use.

[0052] The implementation principle of Embodiment 2 of this application is as follows:

[0053] Rotating gear 71 causes all racks 72 to slide on the connecting frame 6 in mesh with gear 71, causing all unlocking plates 75 to move toward one side of each positioning rod 41, and causing all hemispherical heads 43 to enter each positioning hole 22, thereby enabling all mounting sleeves 21 to simultaneously disengage from the bed frame 1.

[0054] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
