Description

Technical Field

[0001] The utility model relates to the technical field of folding beds, in particular to an extendable bed which is convenient for folding and storing. Background Art

[0002] The relative reduction of modern living area requires home decoration design to make the best possible use of space. Compared with the previous bedrooms that combined entertainment and study functions, modern bedrooms have returned to being spaces for sleeping and resting only. Therefore, from the perspective of the area of ​​modern housing, the bed needs to be designed with a structure that is easy to fold and stretch to achieve the purpose of easy storage. However, the existing folding storage beds still have certain defects during use;

[0003] For example, a foldable and storable multifunctional bed proposed in application number CN202020794554.4 includes a fixed part fixedly mounted on a wall, a movable part embedded outside the fixed part, and a folding plate rotatably mounted on the fixed part and the movable part. The fixed part and the movable part are a box with open sides, and hinges connected to the fixed part and the movable part are provided at both ends of the folding plate, respectively. A rotating part is provided in the middle of the folding plate, and the folding plate is folded along the rotating part, and a soft mattress is placed on the folding plate; a mounting bracket for mounting a display is provided on the movable part, and a mobile phone holder for mounting a mobile phone is installed on the fixed part. In actual use, the multifunctional bed in this application can store the folding plate when not in use, which is convenient for storage and rational use of space. However, after folding and storing, it can only be convenient for storage and save storage space, and cannot be used for other functions after folding, which reduces practicality.

[0004] Therefore, we propose an extendable bed that is easy to fold and store, so as to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-5 The utility model provides a technical solution: an extendable bed that is easy to fold and store, comprising an outer surrounding board 1, connecting shafts 2 are inlaid inside the two sides of the outer surrounding board 1, the inner ends of the connecting shafts 2 are connected to a first bed board 3, the first bed board 3 forms a rotating structure with the outer surrounding board 1 through the connecting shaft 2, a hinge 4 is connected between the first bed board 3 and the second bed board 5, and the first bed board 3 forms a rotating folding structure with the second bed board 5 through the hinge 4, and the second bed board 5 and the third bed board 7 are connected through a hinge 6. The design of the above structure enables the first bed board 3 to be vertically and parallel folded and unfolded inside the outer surrounding board 1 through the connecting shaft 2, and the second bed board 5 can be completely folded and unfolded with the first bed board 3 by using the hinge 4, and the third bed board 7 can be vertically folded and unfolded with the second bed board 5 by using the hinge 6, which is conducive to switching the extendable bed that is easy to fold and store between a sofa state and a bed state.

[0029] A support plate 8 is fixedly installed at the bottom of the third bed board 7, and a moving wheel 9 is installed at the bottom of the support plate 8. The support plate 8 and the moving wheel 9 are symmetrically distributed at the bottom of the third bed board 7. A support seat 10 is fixedly installed on the inner side of the outer surrounding plate 1, and the cross-section of the support seat 10 is arranged in a triangular structure. The design of the above structure enables the moving wheel 9 to smoothly retract and expand the third bed board 7 during the process of pulling out and contracting the third bed board 7, and the setting of the support plate 8 can stably support the folded third bed board 7 and the unfolded first bed board 3, thereby ensuring the stability of the extendable bed that is easy to fold and store.

[0030] A tilting positioning mechanism 11 is connected between the outer enclosure plate 1 and the third bed board 7. The tilting positioning mechanism 11 includes a slide groove 1101 opened inside the two sides of the outer enclosure plate 1. A fixed rod 1102 is fixedly installed inside the slide groove 1101. A connecting plate 1103 is sleeved on the fixed rod 1102. A limiting groove 1104 is opened inside the connecting plate 1103. The connecting plate 1103 and the fixed rod 1102 form a limited sliding structure through the limiting groove 1104. A reset spring 1105 is sleeved on the fixed rod 1102 between the connecting plate 1103 and the slide groove 1101, and the connecting plate 1103 is telescopically connected to the slide groove 1101 through the reset spring 1105. An operating plate 1106 is fixedly installed on the outer end of the connecting plate 1103, and a block 1107 is fixedly installed on the inner end of the connecting plate 1103. The third bed board Slots 1108 are provided at the bottom of both sides of 7, and the connecting plate 1103 forms a locking structure with the third bed board 7 through the locking block 1107 and the locking slot 1108, and the locking slots 1108 are evenly spaced at the bottom of both sides of the third bed board 7. The design of the above structure allows the connecting plate 1103 to slide inside the slide groove 1101 by pressing down the operating plate 1106 and resetting the connecting plate 1103 by the reset spring 1105, and allows the connecting plate 1103 to slide on the fixing rod 1102 through the limiting groove 1104, thereby facilitating the control of the locking block 1107 and the locking slots 1108 at different positions for locking and separation, which is beneficial to adjusting and positioning the protruding length of the third bed board 7 in the outer enclosure board 1, and is also beneficial to adjusting and positioning the inclination angle of the second bed board 5 after folding.

[0031] Working principle: When using this foldable and easy-to-store extendable bed, first Figure 1-5 As shown, when the extendable bed that is easy to fold and store is in a folded state, the connecting plate 1103 can be driven to descend inside the slide groove 1101 by squeezing the operating plate 1106, and the block 1107 can be driven to separate from the slot 1108 at the current position. At this time, the third bed board 7 can be pulled to cooperate with the moving wheel 9 to move. At the same time, the hinge 6 can be used to drive the second bed board 5 to tilt during the movement of the third bed board 7. At the same time, the second bed board 5 will also use the hinge 4 to drive the first bed board 3 to cooperate with the connecting shaft 2 to tilt inside the outer enclosure board 1. When the tilting angle is appropriate, the reset spring 1105 is used to squeeze the connecting plate 1103, so that the connecting plate 1103 drives the block 1107 to engage with the slot 1108 at the corresponding position, which is conducive to positioning the third bed board 7, and then adjusting and positioning the tilting angles of the second bed board 5 and the first bed board 3, and completing the adjustment of the backrest angle in the sofa state;

[0032] By pressing down the operating panel 1106, the engagement between the block 1107 and the slot 1108 can be released, and then by pulling out the third bed board 7, the third bed board 7, the second bed board 5 and the first bed board 3 are arranged in parallel through the connecting shaft 2, the hinge 4 and the hinge 6, thereby completing the unfolding of the extendable bed which is easy to fold and store.
