Description
Technical Field
[0001] This utility model relates to the field of bread bed armrest technology, specifically a synchronous structure that can realize armrest folding and locking. Background Technology
[0002] The bread bed is a design concept that mimics the shape and texture of bread to create a soft, fluffy bed for enhanced sleep comfort. The bread bed can be unfolded or folded away as needed. When unfolded, armrests are installed on all four sides to maintain structural stability. These armrests keep the bed level and support its overall structure. When folding away, the armrests are folded down.
[0003] The existing folding armrest structure of bread-shaped mattresses is poorly designed and quite complex. It requires considerable force to fold and lock, and some designs even require two people to operate, resulting in a poor user experience. Furthermore, the rotation range of the folding armrest structure cannot be accurately limited, and some parts are damaged when rotated too far, leading to poor stability and a short lifespan. Therefore, the inventor has improved the structure of the bread-shaped mattress armrest folding mechanism. Utility Model Content
[0004] The purpose of this utility model is to provide a synchronous structure that can realize the folding and locking of the armrest. This synchronous structure has the advantages of simple structure, reasonable design, convenient use, few operation steps, and saving time and effort. Only one person is needed to quickly complete the folding and locking of the bread bed armrest, achieving a better experience. The rotation range of the steering hand is limited to 90°, avoiding excessive rotation that could cause structural damage, thus improving stability and extending service life. It solves the problems mentioned in the above technical background.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a synchronous structure that enables the folding and locking of a handrail. The synchronous structure includes a protective cover and a locking mechanism disposed inside the protective cover. The locking mechanism includes a fixed base and two sets of storage angles fixed on the fixed base. A bridging plate and a locking element are disposed above the fixed base. Two bridging plates are provided, and each of the two bridging plates has a steering hand that flips synchronously at one end. A locking element is disposed between the two steering hands, and the two steering hands are respectively confined to the two ends of the locking element after being flipped to a horizontal state. A tension spring is provided at the end of each steering hand near the locking element, and the two steering hands are connected to the two sets of storage angles through the two tension springs, thereby realizing the folding and locking of the two steering hands.
[0006] Preferably, the protective cover includes a connecting handle and two faceplates fixed to the connecting handle. The two faceplates are symmetrically arranged at both ends of the connecting handle, and each faceplate is provided with a receiving groove. The two steering hands are respectively disposed in the two receiving grooves at their close ends.
[0007] Preferably, each set of storage corners is provided with two bridge plates, and the two bridge plates are respectively set on the two sets of storage corners. Each bridge plate is set on the inner side of one set of storage corners to limit the movement space of the bridge plate and prevent the bridge plate from shaking.
[0008] Preferably, both bridging plates are V-shaped, and the ends of the two bridging plates that are close to each other are rotatably connected by a shaft.
[0009] Preferably, the locking component includes a main support block, extension strips fixed to both ends of the main support block, and a limiting plate fixed to the bottom of the main support block. The main support block is positioned above the two bridging plates. The two extension strips are in contact with the two bridging plates respectively, and gaps are provided through both extension strips. The ends of the two bridging plates that are close to each other are flipped between the two limiting plates.
[0010] Preferably, the steering hand includes a base block, a limiting hook disposed on the base block, and a protruding block located on one side of the limiting hook. When the base block is flipped and is in a horizontal state, it drives the limiting hook to extend into the gap and contact and connect with the inner wall of the gap. The gap is used to limit the steering hand as a whole, so that the steering hand is kept in a horizontal state. At this time, the bread bed armrest is in a horizontal state.
[0011] Preferably, the tension spring includes a main spring and a flip spring and a positioning spring respectively disposed at both ends of the main spring. The flip spring is connected to the base block, and the positioning spring is connected to the storage corner. When the steering hand is flipped, it drives the main spring and the flip spring to flip, and at the same time the main spring is stretched or released.
[0012] Preferably, it also includes two handrail connecting sleeves, which are symmetrically arranged on the protective cover. The two handrail connecting sleeves are respectively fixed to the ends of the two steering hands that are far apart from each other. The ends of the two handrail connecting sleeves that are far apart from each other are respectively used to connect to two rods on the bread bed handrail, so that the two rods can be closed or locked by means of the protective cover and the locking mechanism.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides a synchronous structure for the folding and locking of a handrail. This synchronous structure includes a protective cover and a locking mechanism disposed inside the protective cover. The overall structure is simple and rationally designed. The locking mechanism includes a fixed base and two sets of storage angles fixed to the fixed base. Each set of storage angles has two angles. A bridge plate and a locking element are disposed above the fixed base. There are two bridge plates in total. A steering handle that rotates synchronously is disposed at the far ends of the two bridge plates. A locking element is disposed between the two steering handles, and after the two steering handles are rotated to a horizontal state, they are respectively confined to the two ends of the locking element. Each of the two steering handles has a tension spring at the end near the locking mechanism. The two steering handles are connected to two sets of retractable corners via the two tension springs. The two tension springs are used to retract and lock the two steering handles. In use, simply rotate the two steering handles 90° to cause the tension springs to deform and separate the two steering handles from the locking mechanism to unlock the bread bed armrests and retract the bread bed. To lock, simply reverse the operation. The overall operation is convenient, with few steps, and saves time and effort. Only one person is needed to quickly retract and lock the bread bed armrests, resulting in a better user experience and making it suitable for widespread use.
[0014] 2. The locking component in this utility model includes a main support block, extension strips fixed to both ends of the main support block, and a limiting plate fixed to the bottom of the main support block. The main support block is positioned above two bridging plates. The two extension strips are respectively connected to the two bridging plates, and gaps are provided through both extension strips. The ends of the two bridging plates that are close to each other are flipped between the two limiting plates. The steering hand includes a base block, a limiting hook provided on the base block, and a protruding block located on one side of the limiting hook. When the base block is flipped, it drives the limiting hook to extend into the gap when it is in a horizontal state and connects with the inner wall of the gap. The gap is used to limit the steering hand as a whole. By setting the extension strips and the gap, the rotation range of the steering hand is limited, so that it can only rotate within a 90° range, avoiding excessive rotation that could cause structural damage, improving stability, and extending service life.

[0019] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.
[0020] Please see Figure 1 The present invention provides an embodiment of a synchronous structure that can realize the folding and locking of the handrail. The synchronous structure includes a protective cover 1 and a locking mechanism 2 disposed inside the protective cover 1. Both ends of the locking mechanism 2 are provided with handrail connecting sleeves 3, and the two handrail connecting sleeves 3 are symmetrically disposed on the protective cover 1.
[0021] Please see Figure 2 The protective cover 1 includes a connecting handle 11 and two faceplates 12 fixed to the connecting handle 11. The two faceplates 12 are symmetrically arranged at both ends of the connecting handle 11. The locking mechanism 2 includes a fixing base 21 and two sets of receiving angles 22 fixed to the fixing base 21. Each set of receiving angles 22 has two angles. A bridging plate 23 and a locking element 24 are arranged above the fixing base 21. There are two bridging plates 23 in total. Both bridging plates 23 are V-shaped, and the ends of the two bridging plates 23 that are close to each other are rotatably connected by a shaft. This shaft is not shown in the attached drawings, but its structure is prior art. Figure 2 As can be seen, the two bridging plates 23 are coaxially arranged at their close ends, and the two bridging plates 23 are respectively provided with steering handles 25 that rotate synchronously at their far ends. A locking member 24 is provided between the two steering handles 25, and the two steering handles 25 are respectively limited to the two ends of the locking member 24 after being rotated to the horizontal state. A tension spring 26 is provided at the end of each steering handle 25 that is close to the locking member 24, and the two steering handles 25 are respectively connected to two sets of storage angles 22 through the two tension springs 26. The two tension springs 26 realize the retraction and locking of the two steering handles 25 respectively.
[0022] Please see Figure 3 Both faceplates 12 are provided with receiving grooves 121, and the two steering hands 25 are respectively located in the two receiving grooves 121 at their close ends.
[0023] Please see Figure 4 Two bridging plates 23 are respectively set on two sets of storage corners 22. Each bridging plate 23 is set on the inner side of one set of storage corners 22, thereby limiting the movement space of the bridging plate 23 and preventing the bridging plate 23 from shaking.
[0024] Please see Figure 5 The locking component 24 includes a main support block 241, extension strips 242 fixed to both ends of the main support block 241, and a limiting plate 243 fixed to the bottom of the main support block 241. The main support block 241 is positioned above the two bridging plates 23. The two extension strips 242 are respectively connected to the two bridging plates 23, and gaps 2421 are provided through both extension strips 242. The ends of the two bridging plates 23 that are close to each other are flipped between the two limiting plates 243. The horizontal steering handle 25 can just enter the gap 2421 and remain horizontal, i.e., locked. When the steering handle 25 is flipped 90°, it becomes vertical, which can complete the folding of the bread bed armrest. At this time, the bread bed is in a folded state. By setting the extension strips 242 and the gaps 2421, the flipping range of the steering handle 25 is limited, so that it can only be flipped within a 90° range, avoiding excessive flipping that could cause structural damage and extending its service life.
[0025] Please see Figure 6 The steering handle 25 includes a base block 251, a limiting hook 252 disposed on the base block 251, and a protruding block 253 located on one side of the limiting hook 252. When the base block 251 is flipped and is in a horizontal state, it drives the limiting hook 252 to extend into the gap 2421 and contact the inner wall of the gap 2421, thereby using the gap 2421 to limit the steering handle 25 as a whole, keeping the steering handle 25 in a horizontal state. At this time, the bread bed armrest is in a horizontal state. The two armrest connecting sleeves 3 are respectively fixed to the two ends of the two steering handles 25 that are far apart from each other. Specifically, the armrest connecting sleeves 3 are fixed to the two base blocks 251, and the ends of the two armrest connecting sleeves 3 that are far apart from each other are respectively used to connect to the two rods on the bread bed armrest, so that the two rods can be closed or locked by means of the protective cover 1 and the locking mechanism 2. Figure 1 and attached Figure 4 The state shown is the locked state. In this state, the bread bed armrests can be kept horizontal and stable, supporting the bread bed. To fold the bread bed armrests, the two rods need to rotate the two armrest connecting sleeves 3 and the two base blocks 251 by 90°, so that the rods on the two armrest connecting sleeves 3 are in a vertical state. During this process, the two tension springs 26 will deform to a certain extent, and the two steering handles 25 will separate from the locking parts 24, thus unlocking the bread bed armrests and folding the bread bed. To lock, simply reverse the above operation. Overall, it is convenient to use, with few operation steps, and saves time and effort. Only one person is needed to quickly fold and lock the bread bed armrests, achieving a better experience.
[0026] Please see Figure 7The tension spring 26 includes a main spring 261 and a flip spring 262 and a positioning spring 263 respectively disposed at both ends of the main spring 261. The flip spring 262 is connected to the base block 251, and the positioning spring 263 is connected to the storage angle 22. When the steering hand 25 is flipped, it drives the main spring 261 and the flip spring 262 to flip, and at the same time the main spring 261 is stretched or released.
[0027] Please see Figure 8 The locking element 24 is fixed between the two faceplates 12, while the protective cover 1 can protect the bridge plate 23, the locking element 24 and the tension spring 26 and other structures.
[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
