Description

Technical Field

[0001] The utility model belongs to the technical field of apartment bed manufacturing, and particularly relates to an apartment bed with a detachable bed frame. Background Art

[0002] After existing apartment beds are manufactured in the factory, the shape and position of the bed frame are usually fixed. For example, in the patent number CN213882578U, which is named "Small Footprint Multifunctional Bed", the bed frame is set at a high height, and then cabinets, tables, chairs, etc. are placed under the bed frame. When studying or working, the bed frame can be used below, and when resting, a ladder can be used to rest above the bed frame.

[0003] The conventional method for securing the bed frame and uprights of an apartment bed is typically as shown in Patent No. CN214803682U, entitled "A Connection Structure for Apartment Bed Tubes." Positioning holes are punched into the uprights, and connecting plugs are provided at the ends of the bed frame's crossbars. These plugs are equipped with positioning plates. During the production of the apartment bed, the positioning plates are inserted into the positioning holes, then bent and clamped to the edges of the holes. The other end of the crossbar is then secured to the opposite upright in the same manner, securing the crossbar to the uprights. Multiple reinforcing rods are then welded between the uprights. This welding process stabilizes the overall shape of the apartment bed. However, since the spacing between the uprights is fixed by the reinforcing rods, removing the crossbars and, consequently, the bed frame, requires removing the reinforcing rods, adjusting the spacing between the uprights, and then breaking open the positioning plates and pulling them out of the positioning holes. This is an extremely inconvenient process, requiring the apartment bed to be transported to a workshop or designated location for removal.

[0004] During normal use, the user usually needs to climb onto the bed frame to rest. In special circumstances, such as when the user of the apartment bed is injured or sick and cannot easily climb up the ladder to rest, the apartment bed is inconvenient to use, and the bed frame cannot be disassembled on site for special use.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] The utility model is an embodiment of an apartment bed with a detachable bed frame, as shown in FIG. Figures 1 to 5 As shown, hereinafter referred to as an apartment bed, a two-person apartment bed will be used as an example. The apartment bed comprises uprights 1 and crossbeams 2. Two uprights 1 are welded together via corresponding reinforcement rods 3 to form a bed frame, and three bed frames are welded together via corresponding reinforcement rods 3 to form a bed frame. Two crossbeams 2 are welded together via corresponding connecting rods 4 to form a bed frame. The bed frame is installed between two adjacent bed frames, with the ends of the crossbeams 2 positioned on the side walls of the corresponding uprights 1.

[0027] The columns 1 and beams 2 have the same cross-sectional shape: rectangular tubular bodies with four chamfered corners. Rounded corners are placed between the outward-facing surfaces of the columns 1 and beams 2 and the chamfered corners on both sides to strengthen the columns 1 and beams 2. A hanger 5 is welded to the end of beam 2. The hanger 5 is a bent plate that matches the shape of the side of the column 1.

[0028] The end of the crossbeam 2 is a solid body 6. In this embodiment, two cavities 9 for accommodating a spring 7 and a slider 8 are vertically distributed within the solid body 6. The cavities 9 are sealed by a hanger 5 on the end face of the crossbeam. The spring 7 is located at the bottom of the cavity 9, and the slider 8 is located near the opening of the cavity 9. In other embodiments, the number of cavities 9 can be set as needed, and can be one, three, or more. The slider 8 slides within the cavity 9. Under the action of the spring 7, the slider 8 rests on the hanger 5. The hanger 5 is provided with a sliding hole 10 corresponding to the cavity 9. The end face of the slider 8 near the hanger 5 is provided with a block 12 protruding from the end face. Under the action of the spring 7, the block 12 can extend out of the sliding hole 10. The bottom of the block 12 is a slot 13, and the top is an arcuate surface 14 that bends downward in the protruding direction. The protruding tip of the block 12 is also an arcuate surface.

[0029] A group of latching holes 11 is provided near the top and bottom of the column 1. Each group of latching holes 11 includes a number of latching holes 11 corresponding to the number of sliding holes 10, and the spacing between the latching holes 11 is equal to the spacing between the sliding holes 10. Under the elastic force of the spring 7, the latching block 12 extends out of the sliding hole 10, and the latching slot 13 is located outside the sliding hole 10. When installing the bed frame, the hanger 5 can be slid from top to bottom along the corresponding contour of the column 1, so that the bed frame slides from top to bottom along the column 1. At this time, under the pressure of the column 1, the latching block 12 shrinks into the sliding hole 10. When the latching block 12 slides to the position of the latching hole 11, the spring 7 causes the latching block 12 to extend into the latching hole 11, and the bed frame continues to move downward, so that the latching slot 13 is locked on the lower edge of the latching hole 11, thereby positioning the bed frame at the position of the latching hole 11.

[0030] Slide grooves 15 are provided on both the upper and lower sides of the cavity 9. The upper slide groove 15 of the cavity 9 in the upper portion of the solid body 6 penetrates the wall of the solid body 6, while the lower slide groove 15 communicates with the cavity 9 in the lower portion of the solid body 6. The lower slide groove 15 of the cavity 9 in the lower portion of the solid body 6 penetrates the wall of the solid body 6. Connecting rods 16 are provided at the upper and lower ends of the slider 8. The connecting rod 16 between the two sliders 8 connects the two sliders 8. The connecting rod 16 at the upper end of the upper cavity slider 8 and the connecting rod 16 at the lower end of the lower cavity slider 8 extend out of the corresponding slide grooves 15 and slide in the corresponding slide grooves 15. The ends of the connecting rods 16 located outside the crossbeam 2 are each provided with a pull block 17. A pull rod 18 is slidably inserted through the pull block 17 and can rotate within the hole of the pull block 17. A stopper 19 is provided at the end of the pull rod 18. The stopper 19 is nested on the side of the pull block 17 facing the column 1 and can rotate and slide within the pull block 17. The pull rod 18 is threadedly connected to a threaded block 21 on the outer wall of the cross beam 2 , and a handle 20 is provided at the other end of the pull rod 18 .

[0031] In this embodiment, since there are two card blocks 12 in the vertical direction, correspondingly, a group of card holes 11 includes two card holes 11. When the lower card block 12 slides to the upper card hole 11, due to the presence of the connecting rod 16, the upper card block 12 still rests on the column, which can prevent the lower card block 12 from being stuck in the card hole 11. Until the lower card block 12 slides to the lower card hole 11 and the upper card block 12 slides to the upper card hole 11, the card block 12 can be stuck in the corresponding card hole 11.

[0032] By turning the handle 20, the pull rod 18 moves along the length of the beam 2, and under the action of the spring force, the pull block 17 can be pressed against the stopper 19. By turning the handle 20, the pull rod 18 moves away from the column 1, and through the stopper 19, the pull block 17, the connecting rod 16, and the slider 8 can be driven to overcome the elastic force of the spring 9, causing the slider 8 and the block 12 to retract.

[0033] When the block 12 is stuck on the hole 11, the handle 20 is turned to overcome the elastic force of the spring 9, so that the slider 8 drives the block 12 to contract, and the slot 13 of the block 12 is pressed against the inner wall of the edge of the hole 11. The handle 20 is released, and the pull block 17 is stuck on the stop block 19 at the end of the pull rod to fix the beam 2 and avoid shaking due to the influence of the spring.

[0034] When the bed frame is close to the top of the upright 1 and the user of the apartment bed needs to lower the bed frame, he first loosens the pull rod 18 so that the slot 13 no longer presses against the inner wall of the edge of the hole, lifts the bed frame upward, and the slot 13 disengages from the hole 11. The arc surface 14 on the top of the block 12 contacts and squeezes the upper edge of the hole 11, so that the block 12 overcomes the elastic force of the spring and shrinks inward until the block 12 completely rises above the hole 11. At the same time, the block 12 disengages from the hole 11 and shrinks into the slide hole 10 and the cavity 9. At the same time, the pull block 17 overcomes the elastic force and disengages from the stopper 19. Then, the handle 20 is turned to make the stopper 19 approach the pull block 17 and press against the pull block 17 to keep the pull block 17 in this position. The block 12 remains in the slider 10 and the cavity 9, and then the bed frame slides down along the column 1. Even if the block 12 passes through the top hole 11, it will not be stuck in the hole 11 due to the obstruction of the stopper 19; when the bed frame approaches the hole 11 at the bottom of the column, the handle 20 is screwed to make the stopper 19 close to the column and no longer block the pull block 17, so that the block 12 can be pressed against the side wall of the column under the action of the spring. As the bed frame continues to descend, when the block 12 reaches the corresponding hole 11, the block 12 enters the hole 11 under the action of the elastic force, and then the slot 13 is stuck at the lower edge of the hole 11. The handle 20 is screwed to make the slot 13 press against the inner wall of the hole edge to fix the block 12.

[0035] When the bed frame is moved from the bottom to the top, the handle 20 can be turned to loosen the slot 13, and the bed frame can be moved upward. The block 12 overcomes the elastic force and disengages from the hole 11 until it moves to the hole 11 at the top of the column. The block enters the hole 11 under the action of the elastic force, and then the slot is stuck on the inner wall of the hole edge, completing the adjustment of the bed frame position.

[0036] By disassembling and assembling the crossbeam and the uprights of the utility model, the bed frame can be moved according to the requirements of the apartment bed user, for example, when the user is injured or sick and cannot climb the ladder, the position of the bed frame can be moved to facilitate the user's rest.

[0037] The top of the ladder 21 on the apartment bed can be fixed to the middle bed frame via a fixing rod 22. When the bed frame is at the top of the apartment bed, the top of the ladder 21 can also rest against the crossbeam 2, increasing strength. When the bed frame is at the bottom of the apartment bed, since the user no longer needs to climb the ladder, the ladder 21 can be fixed to the middle bed frame using only the fixing rod 22.

[0038] A mosquito net rod insertion structure 23 is provided at the top of each column 1. When the bed frame is located at the top of the apartment bed, the mosquito net rod is inserted into the insertion structure 23, and a mosquito net can be set on the mosquito net rod; when the bed frame is located at the bottom of the apartment bed, the mosquito net rod can be removed and the mosquito net can be set on the column 1.

[0039] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
