Abstract
Description
Technical Field
[0001] The present invention relates to the field of bed frame structures, and particularly to a detachable bed frame assembly mechanism. Background Art
[0002] Generally, the volume of a common bed frame is large, and the packaging and transportation costs are high, making it inconvenient to enter a house. There are also some bed frames on the market that can be disassembled for convenient transportation, but these bed frames generally have problems with poor overall stress. At the same time, currently, most detachable beds are opened with the assistance of high-force pneumatic rods. At the beginning, due to the too small angle, there is almost no assisting effect, resulting in very difficult opening. As the angle increases, the assisting force becomes larger and larger, directly leading to the hidden danger of hurting people when bouncing up. During the closing stage, as the angle becomes smaller, the assisting force becomes smaller and smaller, and the closing speed becomes faster and faster, directly leading to the problem of pinching fingers. Even after the pneumatic rod slowly fails, serious safety hazards such as the sudden falling of the upper cover may occur. Summary of the Invention

[0040] The present invention will be further described below through specific embodiments. Embodiment
[0041] As Figures 1-5 shown: A detachable bed frame assembly mechanism, which includes a bed frame body. The bed frame body includes an outer frame, an inner frame and two groups of wooden strips;
[0042] The outer frame is a rectangular frame, which includes two horizontal pipes 1, two vertical pipes 2, four L - shaped iron plate connectors 3, bolts and nuts. The two horizontal pipes and the two vertical pipes are respectively connected by L - shaped iron plates. One L - shaped iron plate is provided at each inner end of the two horizontal pipes. The opening of the L - shaped iron plate faces outward. One side of it is connected to the inner end of the horizontal pipe. The outer end face of the L - shaped iron plate is flush with the outer end face of the horizontal pipe. The end of the vertical pipe connected to it is placed in the opening of the L - shaped iron plate and fixed by bolts and nuts;
[0043] The internal frame includes at least one horizontal connecting pipe 4, several vertical connecting pipes 5, iron sheets 6, bolts and nuts; the horizontal connecting pipe is connected between two vertical pipes and is parallel to the horizontal pipe, several vertical connecting pipes are respectively connected between the horizontal pipe and the horizontal connecting pipe and are parallel to the vertical pipe, and the vertical connecting pipes on both sides of the horizontal connecting pipe are symmetrically arranged; the horizontal connecting pipe and the vertical pipes at its two ends are connected by iron sheets and fixed by bolts and nuts; the vertical connecting pipes and the horizontal pipe are connected by iron sheets and fixed by bolts and nuts, and the end parts of the vertical connecting pipes on both sides of the horizontal connecting pipe are symmetrically arranged outside the horizontal connecting pipe by iron sheets and fixed by locking bolts with nuts.
[0044] The two groups of wooden strips 10 are respectively symmetrically arranged on the upper parts of the horizontal connecting pipe and the horizontal pipes on both sides thereof and are parallel to the vertical pipes, connecting the horizontal connecting pipe and the horizontal pipes; as Figure 8 shown: The two groups of parallel wooden strips are respectively connected into a whole by a webbing 7; using the webbing to combine all the wooden strips into a whole can greatly increase the overall strength and greatly increase the force borne by a single wooden strip; except for wooden strips, this method can be adopted for such strip-shaped methods, as Figure 9 shown: Adding the webbing will have a better effect on the storage and installation of the wooden strips. When storing, only stack the wooden strips back and forth, and when installing, just unfold them. In addition, after the wooden strips are connected by the webbing, they can be better packed during shipment, which is convenient for operation.
[0045] As Figure 10 shown: Using a smaller package makes it more convenient for the purchaser to transport, reduces the transportation cost, not only experiences the fun of DIY during the assembly process, but also allows for more interaction among family members. Embodiment
[0046] As Figures 6-7 shown: A detachable bed frame assembly mechanism, which includes a bed frame body, and the bed frame body includes an external frame, an internal frame and two groups of wooden strips;
[0047] The external frame is a rectangular frame, which includes two U-shaped horizontal pipes 8, two vertical pipes, channel steels 9, bolts and nuts. One end of the channel steel is arranged inside the vertical ends of the two U-shaped horizontal pipes, and the other ends of the two channel steels are arranged inside the two vertical pipes and fixedly connected by bolts and nuts;
[0048] The internal frame includes at least one horizontal connecting pipe, iron sheets, bolts and nuts; the horizontal connecting pipe is connected between two vertical pipes and is parallel to the horizontal pipe, and the horizontal connecting pipe and the vertical pipes at its two ends are connected by iron sheets and fixed by bolts and nuts;
[0049] The two groups of wooden strips are respectively symmetrically arranged on the upper parts of the horizontal connecting pipe and the horizontal pipes on both sides thereof and are parallel to the vertical pipes, connecting the horizontal connecting pipe and the horizontal pipes.
[0050] The present invention uses L-shaped iron plates or channel steels to connect pipe fittings, which is convenient and tight in connection and simple in operation. Such parts are very simple for purchasers to operate, and the overall dimensional control is better after connection. The simple design further reflects the simplicity and beauty of the product;
[0051] Bolts are used for locking to fix and position parts. The operation is simple and direct, and the overall strength is increased by connecting with iron sheets. The difference from ordinary strengthening methods (such as increasing the size and thickness of pipes) is more obvious. After adding sheet metal, the longitudinal force-bearing capacity of the product is greatly increased. Embodiment
[0052] The flip-type link mechanism is as Figures 11-19 、 Figure 21 shown: It includes a box body mounting plate 101, an upper cover mounting plate 102, a first link 103, a second link 104, a pneumatic rod 105 with a small force value, a sliding link 106, a positioning slider 107, a boosting tension spring 108, and a convex block 106-1;
[0053] One end of the box body mounting plate 101 is connected to one end of the first link 103 through the boosting tension spring 108, the other end of the box body mounting plate 101 is connected to one end of the second link 104, and the other end of the first link 103 is connected to one end of the upper cover mounting plate 102; One end of the sliding link 106 is connected to the middle of the second link 104, the other end of the sliding link 106 is connected to the middle of the upper cover mounting plate 102, and the positioning slider 107 slides back and forth along the guide bar 106-2 in the sliding link 106 and rotates through the convex block 106-1 at the lower part of the chute on the sliding link 106; The other end of the second link 104 is connected to the upper cover mounting plate 102 and is located between the first link 103 and the sliding link 106. One end of the pneumatic rod 105 is connected to the other end of the upper cover mounting plate 102, and the other end of the pneumatic rod 105 is located below the sliding link 106 and is connected to the middle of the second link 104;
[0054] Mounting holes are provided on the upper cover mounting plate 102, and mounting holes are also provided on the bed frame body. The mounting holes on the upper cover mounting plate 102 and the mounting holes on the bed frame body are aligned with each other. A bolt-nut assembly is used to sequentially pass through the mounting holes on the upper cover mounting plate 102 and the mounting holes on the bed frame body and tighten them, so as to connect and fix the bed frame body and the flip-type link mechanism.
[0055] The motion principle of the link mechanism:
[0056] The box body mounting plate 101 is fixed below the box body 109 (at the storage function position), and the upper cover mounting plate 102 is fixed to the upper cover 1010. When the upper cover is lifted, it slowly opens under the action of the assisting tension spring to reach the limit opening state, and the positioning slider and the sliding connecting rod also reach the limit state. Then, when the upper cover is pulled downwards, the positioning slider 107 rotates a certain angle under the action of the convex block 106-1 on the sliding connecting rod 106. When the upper cover is pulled downwards again, the positioning slider and the sliding connecting rod will be locked to prevent the upper cover from falling when the pneumatic rod 105 fails. After being lifted to the limit opening state again, the positioning slider drops, and at this time, when it is pressed down again, the locked state will be released, and the upper cover can be pressed downwards. When the upper cover is about to reach the closing state, the assisting tension spring 108 between the box body mounting plate 101 and the first connecting rod 102 provides a certain amount of assistance to prevent sudden falling and closing from hurting the fingers.
[0057] Since the vertical upward force provided by the pneumatic rod at the time of closing is relatively small due to the too large angle of the pneumatic rod, increasing the force value of the pneumatic rod will cause the upper cover to bounce up too quickly when it is lifted. Therefore, in this application, adding the assisting tension spring 108 at the tail end can provide assistance in the closed state, and there is no need to increase the force value of the pneumatic rod 105 to eliminate the safety hazard of the upper cover bouncing up and hurting people;
[0058] The assisting tension spring 108 at the tail end provides assistance when the upper cover is initially lifted to facilitate the lifting of the upper cover, and provides assistance when it is about to be retracted and closed to eliminate the safety hazard of pinching fingers;
[0059] The sliding connecting rod 106 and the positioning slider 107 form a self-locking mechanism. When the upper cover is opened to the limit position and then pressed down again, the self-locking mechanism will lock the upper cover and it will not fall again. When it is lifted and then pulled down, the self-locking is released and the upper cover can be retracted and closed. The self-locking mechanism can eliminate the safety hazard of the upper cover suddenly falling when the pneumatic rod fails in the open state;
[0060] The pneumatic rod 105, the second connecting rod 104, and the upper cover mounting plate 102 form a triangular structure, and the mechanism is more stable when it is opened and closed;
[0061] Such as Figure 20 shown: This application has a self-locking structure and can also be used for the wall bed structure 1011 to prevent rebound.
