Description

Technical Field

[0001] The utility model relates to the technical field of bedsteads, and specifically, it is a quickly disassembled and assembled storage bed. Background Art

[0002] The storage bed is one of the commonly used types of bedsteads. People can store extra items under the bed surface frame of the storage bed to make full use of the space under the bed surface frame of the storage bed.

[0003] A Chinese patent application document is disclosed in the prior art, with the publication number CN115590329A, which includes: a bed support frame and a bed surface frame. At least one top support assembly is installed between the bed surface frame and the bed support frame. The top support assembly includes a gas spring, a head connecting piece, a tail connecting piece, a lower fixing piece, an upper fixing piece, a large gear and a small gear. The upper fixing piece is fixed on the bed surface frame, the lower fixing piece is fixed on the bed support frame, the large gear is fixed on the head connecting piece, the small gear is fixed on the lower fixing piece or the upper fixing piece, and the small gear can only mesh with the large gear in the upward direction. The gas spring and the tail connecting piece are both pivotally connected between the upper fixing piece and the lower fixing piece. An included angle is formed between the gas spring and the tail connecting piece. One end of the gas spring is pivotally connected to one end of the tail connecting piece, which can reduce the risk of the tail of the lifted bed surface frame flipping and falling when the supporting force of the gas spring is insufficient.

[0004] However, the prior art does not consider how to perform quick disassembly and assembly. For the convenience of transportation, most similar products on the market disassemble the iron frame (corresponding to the bed surface frame in the existing patent application document) and package it, and then the user assembles it during use. Most of the assembly is carried out by using bolts and pins, which is very inconvenient. Content of the Utility Model

[0005] The purpose of the utility model is to provide a quick disassembly and assembly mechanism and a quickly disassembled and assembled storage bed, so as to improve the existing installation method.

[0006] The purpose of the utility model is realized in this way: a quick disassembly and assembly mechanism is used for the plug-in fit of a male connecting part and a female connecting part. It includes an elastically telescopic elastic member, and at least one positioning pin fixedly connected to the elastic member;

[0007] During plug-in connection, the elastic member is elastically installed inside the male connecting part, and under the elastic force of the elastic member, the positioning pin is simultaneously inserted into the positioning holes provided on the male connecting part and the female connecting part.

[0008] Furthermore, the elastic member is set as a metal member formed by bending to have elasticity.

[0009] Furthermore, the positioning pin is integrally connected with the elastic member.

[0010] Further, the elastic member elastically expands and contracts along the insertion direction of the positioning pin.

[0011] Further, at least two positioning pins are provided.

[0012] Further, the positioning pins are staggeredly distributed and not on the same horizontal line.

[0013] As another aspect of the present patent, a quick-disassembly and quick-assembly type storage bed configured with several of the above-mentioned quick-disassembly and quick-assembly mechanisms is proposed, including a bed body and a bed board installed in the bed body. The edge part of the bed board is set as a bed board frame, and the bed board frame is detachably plugged and connected by several hollow pipe fitting units, and each plug-in point is configured with the above-mentioned quick-disassembly and quick-assembly mechanism.

[0014] Further, the bed body includes a cross beam member for supporting the bed board frame. The cross beam member has a cross beam rod horizontally extending along the bed width direction and two legs for supporting the ground. Both ends of the cross beam rod are configured with the quick-disassembly and quick-assembly mechanism and are detachably and fixedly connected to the upper ends of the two legs through the quick-disassembly and quick-assembly mechanism.

[0015] Further, the end of the cross beam rod is rotatably connected to the upper end of the leg, and the rotation connection point of the cross beam rod and the leg is set as a folding and unfolding fulcrum and is staggeredly distributed from the quick-disassembly and quick-assembly mechanism. When disassembling, the quick-disassembly and quick-assembly mechanism is unlocked, and the cross beam rod is rotated and folded to be parallel and attached to the leg.

[0016] Further, at least one baffle rod bent into a U shape is provided on the front side or the rear side of the bed board frame. The baffle rod is used to block the mattress. Each baffle rod is correspondingly provided with two baffle rod lock holes opened on the bed board frame. The distance between the two baffle rod lock holes is smaller than the distance between the two arm parts of the baffle rod. The two arm parts of the baffle rod are respectively detachably inserted into the two baffle rod lock holes, and under the elastic action of the baffle rod itself, the two arm parts of the baffle rod are respectively locked and matched with the two baffle rod lock holes.

[0017] The beneficial effects of the present utility model are as follows:

[0018] 1. The bed board frame itself is set as a detachable and assembled split structure, assembled by a specially designed quick-disassembly and quick-assembly mechanism, and the quick-disassembly and quick-assembly mechanism can be unlocked without the assistance of tools. When disassembling, only need to press the positioning pin to unlock the quick-disassembly and quick-assembly mechanism. When assembling, the elastic expansion and contraction of the elastic member itself can be relied on to drive the positioning pin to be inserted into the positioning hole for quick disassembly;

[0019] 2. The two legs at both ends of the cross bracing beam assembly are rotatably connected to the cross beam rod, enabling the two legs at both ends to be folded and unfolded. When packaging, unlock the quick disassembly and assembly mechanism, causing the legs at both ends to rotate and fold around the rotation connection point, further reducing the packaging size. When in use, the legs at both ends can be unfolded, and the installation positions of the legs at both ends can be locked using the quick disassembly and assembly mechanism to meet the support requirements.

[0020] 3. The retaining rod for limiting the position of the mattress can be quickly disassembled and assembled. When the user installs it, they can directly insert the retaining rod into the bed board frame without using installation tools, which is quick and convenient. To prevent the retaining rod from loosening, in this patent, the distance between the retaining rod lock holes is smaller than the distance between the two arm portions of the retaining rod. When installing, the operator only needs to hold the retaining rod tightly so that the two arm portions of the retaining rod can be smoothly inserted into the two retaining rod lock holes. After releasing the hand, the two arm portions of the retaining rod generate a pre-tightening force with the retaining rod lock holes under the action of the elastic rebound of their own elasticity, driving the two arm portions of the retaining rod to form a tight fit with the two retaining rod lock holes, achieving the effect of automatic anti-loosening.

[0028] The following will combine the attached drawings in the embodiments of the present utility model Figures 1-7 , and clearly and completely describe the technical solutions in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0029] Such as Figure 1Shown is a quickly disassemblable storage bed, including a bed body, a bed board, and a four-bar linkage mechanism 7.

[0030] The main structure of the bed body includes a surrounding frame 8 and a backrest 9. The surrounding frame 8 has a front side plate and left and right side plates, which enclose to form an internal storage space. The backrest 9 is vertically arranged and fixedly connected to the left and right side plates of the surrounding frame 8. The front side of the bed board is connected to the left and right side plates of the surrounding frame 8 through the four-bar linkage mechanism 7 for up-and-down flipping adjustment. The bed board can be adjusted up and down to open / close the internal storage space. These are all settings of common knowledge and have been described in the patent with the publication number CN115590329A.

[0031] The bed board includes a bed board frame 1 (iron frame), a number of rib strips 6, and two longitudinal support beams 5. The bed board frame 1 is a rectangular frame structure and is the edge part of the bed board. A number of rib strips 6 are arranged at equal intervals along the bed length direction and are detachably connected to the bed board frame 1. The rib strips 6 extend along the bed width direction. The two longitudinal support beams 5 are detachably connected to the bed board frame 1 and are distributed left and right. The two longitudinal support beams 5 are below the rib strips 6. When disassembling, both the rib strips 6 and the longitudinal support beams 5 can be removed.

[0032] In this embodiment, compared with the prior art, significant improvements have been made in the quick disassembly and assembly scheme, and a quick disassembly and assembly mechanism is proposed, which is used for the plug-in fit of a male connection part and a female connection part. It includes an elastically telescopic elastic member 2 and at least one positioning pin 2a fixedly connected to the elastic member 2.

[0033] Refer to Figure 3 、 6 As shown, when plugging in, the elastic member 2 is elastically installed inside the male connection part. Under the elastic force of the elastic member 2, the positioning pin 2a is simultaneously inserted into the positioning holes provided on both the male connection part and the female connection part. When unlocking, only need to press the positioning pin 2a to unlock the quick disassembly and assembly mechanism.

[0034] The above elastic member 2 is set as a metal member formed by bending to form elasticity. The positioning pin 2a is integrally connected with the elastic member 2, and the elastic member 2 elastically expands and contracts along the insertion direction of the positioning pin 2a.

[0035] According to Figure 3 As shown in the enlarged view in, the elastic member 2 is a V-shaped bent plate, or other structural forms, and can perform lateral elastic expansion and contraction. As long as it has elastic expansion and contraction performance, the choice of setting the elastic member 2 as other structural forms is not excluded.

[0036] The above positioning pin 2a is at least one, which means that the positioning pin 2a can be one or two, or more than two.

[0037] According to Figure 3As shown in the enlarged view, there can be two positioning pins 2a, which is beneficial to ensuring the stability after assembly. The two positioning pins 2a are staggeredly distributed and not on the same horizontal line. During the disassembly and assembly process, only one press on the elastic member 2 is required to unlock.

[0038] As Figure 3 , 4 shown, the above-mentioned quick disassembly and assembly mechanism can be applied to the quick disassembly and assembly scheme of the bed board frame 1. Specifically:

[0039] The above bed board frame 1 is detachably plugged and connected by a plurality of hollow pipe fittings units, and the above-mentioned quick disassembly and assembly mechanism is configured at each plugging point. This quick disassembly and assembly mechanism has two positioning pins 2a, and the connection line of the two positioning pins 2a is inclined.

[0040] As Figure 3 , 4 shown, the rectangular bed board frame 1 is divided into front and rear end bars (C-shaped) and left and right side bars. The end bars and side bars are all hollow pipe fittings. The plugging ends of the left and right side bars are provided with male connection parts, that is, hollow positioning parts 1a. Two locking holes 1b are opened on the positioning part 1a, and the connection line of the two locking holes 1b is inclined, corresponding to the two positioning pins 2a. The plugging ends of the front and rear end bars are set as female connection parts, and two positioning holes 1c are opened. The connection line of the two positioning holes 1c is inclined. During plugging, the elastic member 2 is elastically installed within the positioning part 1a. The positioning part 1a is inserted into the inner hole of the end bar. The two positioning holes 1c are respectively aligned with the two locking holes 1b. Relying on the self-elastic force of the elastic member 2, the two positioning pins 2a are driven to plug into both the two positioning holes 1c and the two locking holes 1b (as Figure 4 shown), so that the end bar and the side bar form an assembled relationship. During disassembly, only need to press the positioning pin 2a by hand and compress the elastic member 2 at the same time, so that the two positioning pins 2a are disengaged from the positioning holes 1c and the locking holes 1b, and then quick disassembly can be carried out. The removed front and rear end bars and left and right side bars are convenient for placement and packaging, thus laying a foundation for saving packaging space.

[0041] It is worth mentioning that the above plugging method can be determined according to project requirements, not limited to the embodiments listed in this patent.

[0042] As Figures 5-7 shown, the above-mentioned quick disassembly and assembly mechanism can be applied to the quick disassembly and assembly scheme of the cross brace beam component 3. Specifically:

[0043] The cross brace beam component 3 that supports the bed board frame 1. The cross brace beam component 3 has a cross beam rod 3a that horizontally extends along the bed width direction and two legs 3b for supporting the ground. Both ends of the cross beam rod 3a are configured with the above-mentioned quick disassembly and assembly mechanism and are detachably connected to the upper ends of the two legs 3b through the quick disassembly and assembly mechanism.

[0044] Specifically, a fixing seat (serving as a female connecting part) is fixed to the upper end of the outrigger 3b. The fixing seat has a pair of parallel ear plates 3c. A slot for inserting the cross beam rod 3a is provided between the two ear plates 3c. The connecting end of the cross beam rod 3a serves as a male connecting part. There is only one positioning pin 2a for the quick disassembly and assembly mechanism matching this connecting part (the possibility of setting multiple ones is not excluded). Mounting positioning holes 3d are provided on the ear plates 3c, and positioning holes are opened on the cross beam rod 3a. The elastic member 2 is elastically mounted inside the cross beam rod 3a. During assembly, the mounting positioning holes 3d of the ear plates 3c are aligned with the positioning holes of the cross beam rod 3a. The positioning pin 2a is inserted into the mounting positioning holes 3d of the ear plates 3c and the positioning holes of the cross beam rod 3a under the urging of the elastic force of the elastic member 2. During disassembly, only need to press the positioning pin 2a by hand to release the locking of the outrigger 3b.

[0045] As an auxiliary solution, the fixing seat at the upper end of the outrigger 3b also has a connecting plate that is detachably connected to the surrounding frame 8. This connecting plate is fixedly connected to the ear plates 3c.

[0046] The end of the above-mentioned cross beam rod 3a is rotatably connected to the upper end of the outrigger 3b through a rivet 3e. The rotation connection point of the cross beam rod 3a and the outrigger 3b is set as the folding and unfolding fulcrum, and is staggeredly distributed from the quick disassembly and assembly mechanism. When disassembling, unlock the quick disassembly and assembly mechanism, so that the outrigger 3b can rotate and move. After rotating and folding, the cross beam rod 3a and the outrigger 3b are parallel and adjacent to each other, thereby further saving the packaging space to reduce the transportation cost.

[0047] As shown in Figure 2 As shown, two U-shaped (iron rod) retaining bars 4 are provided on the front side of the above-mentioned bed board frame 1. The retaining bars 4 are used to block the mattress. Each retaining bar 4 is correspondingly provided with two retaining bar lock holes 1d opened on the bed board frame 1. The distance between the two retaining bar lock holes 1d is smaller than the distance between the two arm parts of the retaining bar 4. Since the retaining bar 4 is a U-shaped rod-like structure and has sufficient elasticity itself, the two arm parts of the retaining bar 4 are respectively detachably inserted into the two retaining bar lock holes 1d, and under the elastic action of the retaining bar 4 itself, the two arm parts of the retaining bar 4 are respectively locked and fitted with the two retaining bar lock holes 1d.

[0048] As one of the structural improvement solutions, since the bed board frame 1 is made of hollow pipe fittings, a hollow sleeve such as a bushing or a rivet nut can be fixedly inserted into the retaining bar lock hole 1d, so that the arm part of the retaining bar 4 can be fixedly inserted into the hollow sleeve, which can increase the fixing surface of the retaining bar 4, thereby improving the reliability and firmness of the installation of the retaining bar 4.

[0049] The retaining rod 4 for limiting the position of the mattress can be quickly disassembled and assembled. When the user installs it, the retaining rod 4 can be directly inserted into the bed board frame 1 without using installation tools, which is quick and convenient. To prevent the retaining rod 4 from loosening, in this patent, the distance between the retaining rod lock holes 1d is smaller than the distance between the two arm parts of the retaining rod 4. During installation, the operator only needs to hold the retaining rod 4 firmly so that the two arm parts of the retaining rod 4 can be smoothly inserted into the two retaining rod lock holes 1d. After releasing the hand, the two arm parts of the retaining rod 4 generate a pre-tightening force with the retaining rod lock holes 1d under the action of the elastic rebound of their own, driving the two arm parts of the retaining rod 4 to form a tight fit with the two retaining rod lock holes 1d, achieving the effect of automatic anti-loosening.
