Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and more specifically, to a crib frame structure and a crib. Background Technology

[0002] A crib is a commonly used medical device, primarily used to place an infant and provide a safe and comfortable resting environment. Currently, the crib frame is an important component, upon which a baby carrier can be placed to accommodate the infant.

[0003] In related technologies, bed frame structures often include a base plate, and the entire bed frame structure is usually screwed to the upper end of the lifting column. However, the base plate covers the bolts at the connection between the bed frame structure and the lifting column. This means that when the lifting column needs to be inspected, the base plate must first be removed to expose the bolts before the bolts can be manipulated to remove the entire bed frame structure from the lifting column. Then the lifting column can be inspected, which is quite cumbersome and causes inconvenience in the maintenance of the lifting column. Utility Model Content

[0010] Optionally, it also includes a gas spring, one end of which is hinged to the bottom surface of the first reinforcing rod, and the other end of which is hinged to the side wall of the lifting column.

[0011] Optionally, the support frame further includes a connecting rod, the two ends of which are respectively connected to the first reinforcing rod and the second reinforcing rod, and the orthographic projection of the connecting rod on the horizontal plane is offset from the orthographic projection of the through hole assembly on the horizontal plane.

[0015] Secondly, this utility model provides a crib, including the crib frame structure described above.

[0028] This utility model provides a crib frame structure, which will be described in detail below with reference to specific embodiments.

[0029] like Figures 1 to 3As shown in the figure, an embodiment of the present invention provides a crib frame structure, including a mounting tube 1 and a support frame 2. The mounting tube 1 is arranged horizontally, and the lower tube wall of the mounting tube 1 is provided with a connecting hole group 11. The connecting hole group 11 is used to connect to the lifting column 6 below the mounting tube 1 through fasteners 3. The upper tube wall of the mounting tube 1 is provided with a through hole group 12. The through holes of the through hole group 12 and the connecting holes of the connecting hole group 11 are respectively arranged vertically opposite to each other, and the diameter of the through holes of the through hole group 12 is larger than the diameter of the connecting holes of the connecting hole group 11. The support frame 2 is used to support the receiving frame 7. The support frame 2 includes a first support rod 21, a second support rod 22 and a reinforcing rod. The first support rod 21 and the second support rod 22 are spaced apart along the length direction of the mounting tube 1 and are respectively connected to the two ends of the mounting tube 1. The two ends of the reinforcing rod are respectively connected to the first support rod 21 and the second support rod 22. The orthographic projection of the reinforcing rod on the horizontal plane is offset from the orthographic projection of the through hole group 12 on the horizontal plane.

[0030] Specifically, fastener 3 can be a bolt. It should be noted that the connecting hole group 11 can include two or more connecting holes, and correspondingly, the through hole group 12 can also include two or more through holes. It should also be noted that there is no limitation on the number of reinforcing rods; it can be one, two, or more. When there is more than one reinforcing rod, both ends of each reinforcing rod are connected to the first support rod 21 and the second support rod 22 respectively, and the orthographic projection of each reinforcing rod in the horizontal plane is offset from the orthographic projection of the through hole group 12 in the horizontal plane. Additionally, refer to... Figure 1 The support frame 2 may also include multiple baffles 23, baffle rings 24, and storage boxes 25. The multiple baffles 23 are arranged vertically, and the lower ends of the multiple baffles 23 are connected to the first support rod 21 or the second support rod 22. The baffle rings 24 are arranged horizontally and are connected to the upper ends of the multiple baffles 23. The first support rod 21, the second support rod 22, the reinforcing rod, the multiple baffles 23, and the baffle rings 24 form a placement space for the receiving frame 7 to hold the items. The storage boxes 25 are suspended on the baffle rings 24 for placing items.

[0031] In this embodiment, by aligning the through-hole group 12 on the upper wall of the mounting tube 1 with the connecting hole group 11 on the lower wall of the mounting tube 1, and ensuring that the diameter of the through-holes in the through-hole group 12 is larger than the diameter of the connecting holes in the connecting hole group 11, the head of the fastener 3 can be hidden inside the cavity of the mounting tube 1 after passing through the connecting hole group 11 to connect the mounting tube 1 and the lifting column 6, thus avoiding exposure to the outside of the mounting tube 1 and improving aesthetics. By connecting the two ends of the reinforcing rod to the first support rod 21 and the second support rod 22 respectively, the entire support frame 2 can form a frame structure. The reinforcing rod can replace the original base plate to strengthen the support frame 2, so as to reliably support the housing frame 7. By making the orthographic projection of the reinforcing rod on the horizontal plane and the orthographic projection of the through hole group 12 on the horizontal plane staggered, the through hole group 12 can be exposed through the support frame 2. In this way, when it is necessary to inspect the lifting column 6, the fasteners 3 at the position of the connecting hole group 11 can be disassembled directly through the exposed through hole group 12, thereby removing the bed frame structure from the lifting column 6 for inspection and maintenance of the lifting column 6 without disassembling the base plate, thus improving the convenience of inspection and maintenance of the lifting column 6.

[0032] Optionally, such as Figure 1 As shown, the reinforcing rod includes a first reinforcing rod 26 and a second reinforcing rod 27. The two ends of the first reinforcing rod 26 are respectively connected to the front end of the first support rod 21 and the front end of the second support rod 22. The two ends of the second reinforcing rod 27 are respectively connected to the rear end of the first support rod 21 and the rear end of the second support rod 22. The mounting tube 1 is located between the first reinforcing rod 26 and the second reinforcing rod 27.

[0033] It is understood that the number of reinforcing rods in this embodiment is two, while in some other embodiments, the number of reinforcing rods may be three, four or more.

[0034] In this optional embodiment, the two ends of the first reinforcing rod 26 are respectively connected to the front end of the first support rod 21 and the front end of the second support rod 22, and the two ends of the second reinforcing rod 27 are respectively connected to the rear end of the first support rod 21 and the rear end of the second support rod 22, so that the first reinforcing rod 26, the second reinforcing rod 27, the first support rod 21 and the second support rod 22 can be connected to form a square structure, which is beneficial to improving the structural strength of the entire support frame 2; the mounting tube 1 is located between the first reinforcing rod 26 and the second reinforcing rod 27, so that the orthographic projection of the through hole group 12 of the mounting tube 1 on the horizontal plane is offset from both the orthographic projection of the first reinforcing rod 26 on the horizontal plane and the orthographic projection of the second reinforcing rod 27 on the horizontal plane, so as to ensure that the through hole group 12 can be exposed through the support frame 2.

[0035] Optionally, such as Figure 1As shown, the top surfaces of the first reinforcing rod 26, the second reinforcing rod 27, the first support rod 21, and the second support rod 22 are coplanar to jointly support the receiving frame 7.

[0036] Specifically, the first support rod 21 and the second support rod 22 are both round rods, and the first reinforcing rod 26 and the second reinforcing rod 27 are both square rods. The top surface of the first support rod 21 is the horizontal plane where its upper generatrix is ​​located, the top surface of the second support rod 22 is the horizontal plane where its upper generatrix is ​​located, the top surface of the first reinforcing rod 26 is its upward-facing side, and the top surface of the second reinforcing rod 27 is its upward-facing side.

[0037] In this optional embodiment, the top surfaces of the first reinforcing rod 26, the second reinforcing rod 27, the first support rod 21, and the second support rod 22 are coplanar, which can relatively increase the contact area with the bottom surface of the receiving frame 7, making the support more stable.

[0038] Optionally, the first reinforcing rod 26 has a cavity extending along its length, and the second reinforcing rod 27 has a cavity extending along its length.

[0039] Specifically, the two ends of the first reinforcing rod 26 can be welded to the first support rod 21 and the second support rod 22 respectively to ensure the reliability of the connection between the first reinforcing rod 26 and the two support rods; the two ends of the second reinforcing rod 27 can be welded to the first support rod 21 and the second support rod 22 respectively to ensure the reliability of the connection between the second reinforcing rod 27 and the two support rods.

[0040] In this optional embodiment, a through cavity is designed in the first reinforcing rod 26 to form a hollow structure. This reduces the mass of the first reinforcing rod 26, thereby lowering the cost of the bed frame structure, and also increases the bending rigidity of the first reinforcing rod 26, making the bed frame structure less prone to bending and deformation. Similarly, a through cavity is designed in the second reinforcing rod 27 to form a hollow structure. This reduces the mass of the second reinforcing rod 27, thereby lowering the cost of the bed frame structure, and also increases the bending rigidity of the second reinforcing rod 27, making the bed frame structure less prone to bending and deformation.

[0041] In related technologies, bed frame structures often include gas springs 4, with the bottom plate and lifting column 6 connected to the two ends of the gas springs 4 respectively. The gas springs 4 extend and retract to change the tilt angle between the bed frame structure and the horizontal plane, thereby achieving the tilt angle adjustment function. However, the bottom plate is relatively thin, and the force generated by the extension and retraction of the gas springs 4 can easily cause deformation of the bottom plate, thereby causing damage to the entire bed frame structure.

[0042] In view of this, alternatively, such as Figure 1As shown, the crib frame structure also includes a gas spring 4, one end of which is hinged to the bottom surface of the first reinforcing rod 26, and the other end of which is hinged to the side wall of the lifting column 6.

[0043] In this optional embodiment, the first reinforcing rod 26 is hinged to the gas spring 4 instead of the base plate. Compared with the base plate, the first reinforcing rod 26 has higher strength and is therefore less prone to deformation when subjected to the force of the gas spring 4, which can prevent the entire bed frame structure from deforming and being damaged.

[0044] Furthermore, such as Figure 1 As shown, the width of the second reinforcing rod 27 is smaller than the width of the first reinforcing rod 26. Since the first reinforcing rod 26 needs to be connected to the gas spring 4, while the second reinforcing rod 27 does not, the second reinforcing rod 27 typically provides less structural strength than the first reinforcing rod 26. However, this solution sets the width of the second reinforcing rod 27 to be smaller than the width of the first reinforcing rod 26. Compared to using the same or larger width for the second reinforcing rod 27 as the first reinforcing rod 26, the total mass of the two reinforcing rods can be relatively reduced, thereby reducing the material cost of the entire bed frame structure.

[0045] Optionally, in some other embodiments, the support frame 2 further includes a connecting rod, the two ends of which are respectively connected to the first reinforcing rod 26 and the second reinforcing rod 27, and the orthographic projection of the connecting rod on the horizontal plane is offset from the orthographic projection of the through hole group 12 on the horizontal plane.

[0046] Specifically, the top surface of the connecting rod can be coplanar with the top surface of the first reinforcing rod 26 and the top surface of the second reinforcing rod 27, which can further increase the contact area with the bottom surface of the receiving frame 7 and improve the stability of the support for the receiving frame 7.

[0047] In this optional embodiment, by connecting the two ends of the connecting rod to the first reinforcing rod 26 and the second reinforcing rod 27 respectively, the structural strength of the support frame 2 can be further enhanced; in addition, by staggering the orthographic projection of the connecting rod on the horizontal plane with the orthographic projection of the through hole group 12 on the horizontal plane, the connecting rod can be prevented from blocking the through hole group 12, so as to facilitate the disassembly of the fastener 3.

[0048] Furthermore, in some other embodiments, the support frame 2 may also include diagonal braces, with both ends of the diagonal braces connected to one of the first reinforcing rod 26 and the second reinforcing rod 27, and one of the first support rod 21 and the second support rod 22, respectively. The orthographic projection of the diagonal brace on the horizontal plane is offset from the orthographic projection of the through hole assembly 12 on the horizontal plane. For example, the two ends of the diagonal brace are connected to the first reinforcing rod 26 and the first support rod 21, respectively. In this way, the diagonal brace can strengthen the connection between the first reinforcing rod 26 and the first support rod 21, thereby improving the structural stability of the support frame 2 and making the support frame 2 less prone to deformation.

[0049] Optionally, such as Figure 1 and Figure 4 As shown, the crib frame structure also includes a rubber plug 5, which is used to be inserted into the through hole of the through hole group 12.

[0050] In this optional embodiment, by designing the rubber plug 5, when the lifting column 6 is not under maintenance, the rubber plug 5 can be inserted into the through hole of the through hole group 12 to cover the through hole, prevent the through hole from being exposed for a long time, and thus avoid the situation where foreign objects accidentally fall into the through hole when the receiving frame 7 is replaced.

[0051] It should also be noted that in related technologies, when the bed frame structure is equipped with a base plate, the base plate is often installed by bolt connection. However, in this optional embodiment, the rubber plug 5 is inserted into the through hole of the through hole group 12. The time it takes for the rubber plug 5 to be pulled out of the through hole is negligible compared to the time it takes to remove the bolts to take off the base plate, and it will not affect the convenience of maintenance of the lifting column 6.

[0052] Optionally, such as Figure 1 and Figure 4 As shown, both the first support rod 21 and the second support rod 22 are provided with a downwardly protruding connecting plate 28, and the connecting plate 28 is provided with a first through hole; both ends of the mounting tube 1 are respectively provided with sealing plates 13, and the sealing plates 13 are provided with second through holes; the crib frame structure also includes a screw connector 281, which is sequentially inserted through the first through hole and the second through hole to fix the connecting plate 28 and the sealing plate 13 relative to each other.

[0053] In this optional embodiment, the screw connector 281 is sequentially inserted through the first through hole of the connecting plate 28 and the second through hole of the sealing plate 13, which can fix the connecting plate 28 and the sealing plate 13 relative to each other, thereby realizing the connection of the first support rod 21 and the second support rod 22 to the two ends of the mounting tube 1. The structure is simple and the assembly is relatively convenient.

[0054] Furthermore, the sealing plate 13 is welded to the mounting tube 1 to ensure a reliable connection between the mounting tube 1 and the sealing plate 13. Additionally, the sealing plate 13 may have positioning protrusions on its periphery, and the mounting tube 1 has positioning grooves that mate with the positioning protrusions. Thus, before welding the sealing plate 13 to the mounting tube 1, the positioning protrusions and positioning grooves can be used to position the sealing plate 13 accurately within the mounting tube 1, thereby improving the assembly accuracy of the sealing plate 13 and the mounting tube 1.

[0055] Optionally, such as Figure 4 As shown, the lower wall of the mounting tube 1 is provided with an exposure port 14, and the inner side of the sealing plate 13 is exposed to the lower part of the mounting tube 1 through the exposure port 14.

[0056] In this optional embodiment, the inner side of the sealing plate 13 can be exposed to the underside of the mounting tube 1 through the exposure port 14, so that the operator can operate on the part of the screw connector 281 that extends into the inner side of the sealing plate 13 through the exposure port 14, such as installing and removing nuts on the screw connector 281, which facilitates the assembly of the connecting plate 28 and the sealing plate 13.

[0057] like Figure 5 As shown in the figure, an embodiment of the present invention provides a crib, including the crib frame structure described above.

[0058] It should be noted that the crib may also include a lifting column 6, a storage frame 7, a base 8, and a storage box 9, etc., without specific limitations.

[0059] In this embodiment, since the crib includes the crib frame structure described above, it possesses all the beneficial effects of all embodiments of the crib frame structure described above, which will not be repeated here.

[0060] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
