Description

[0002] Apartments are usually rented out for a short period of time. In order to consider the cost of furnishing the apartment, the landlords usually use cheap furniture that is mass-produced in factories and the furniture cannot be adjusted for suitability.
[0003] Due to the high mobility of residents in apartments, furniture may not be able to meet the needs of different tenants. For example, tenants of different heights have different requirements for the length and height of the apartment bed.
[0004] In order to solve the problem of different heights of apartment beds, apartment beds generally use height-adjustable support legs to adjust the height of the bed, or use a lifting component to adjust the height of the bed frame. Under normal circumstances, the lifting component generally uses an electric cylinder or an electric push rod. The telescopic rod of the electric cylinder or electric push rod is extended or shortened by electricity to adjust the height of the bed. When the bed height reaches the set height, the telescopic rod is locked using the locking component of the electric cylinder or electric push rod. After the height of the bed frame is adjusted, the weight of the tenant and the weight of the bed itself are transferred to the telescopic rod. If the tenant rolls back and forth on the bed, it is easy to cause the bed to shake, which is easy to damage the locking components inside the electric cylinder or electric push rod, thereby affecting the lifting function of the bed.

DETAILED DESCRIPTION
[0027] The technical solutions in the embodiments of the utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of 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] The present embodiment provides an adjustable apartment bed, which is mainly used to adjust the height of the apartment bed, thereby improving the stability of the apartment bed and reducing the risk of damage to the locking components inside the electric push rod or the electric cylinder due to weight and shaking.
[0029] like Figure 1 As shown, the apartment bed includes a load frame 1 and a support portion 2 for supporting the load frame 1, wherein the load frame 1 is used to place a mattress of the apartment bed, the load frame 1 and the support portion 2 are two independent parts, the bottom of the support portion 2 is placed on the ground, and the load frame 1 can be pushed upward under the action of a lifting assembly to achieve relative movement between the load frame 1 and the support portion 2, so that the height of the load frame 1 can be adjusted to meet the needs of tenants of different heights.
[0030] Specifically, the support portion 2 includes a support leg assembly 21 and a support assembly 22. Figure 1 , Figure 2 and Figure 6 As shown, there are two groups of support leg assemblies 21, which are located below the support frame 1, and the two groups of support leg assemblies 21 are arranged opposite to each other. The supporting assembly 22 is installed between the two support leg assemblies 21, and the supporting assembly 22 is parallel to the ground.
[0031] Specifically, in this embodiment, if Figure 6As shown, the support leg assembly 21 includes a first longitudinal beam 211 and a plurality of support legs 212, wherein the first longitudinal beam 211 and the support legs 212 are both made of steel square tubes, the first longitudinal beam 211 is arranged along the length direction of the carrier frame 1, and the plurality of support legs 212 are welded to the first longitudinal beam 211, and the bottom of the support legs 212 is in contact with the ground.
[0032] In this embodiment, three supporting legs 212 are installed on each first longitudinal beam 211 .
[0033] like Figure 5 and Figure 6 As shown, the supporting assembly 22 includes two second longitudinal beams 221, a plurality of cross beams 222 and C-shaped steels 223, wherein the two second longitudinal beams 221 are arranged along the length direction of the apartment bed, a plurality of cross beams 222 are installed between the two second longitudinal beams 221, and the cross beams 222 are used to fix the two second longitudinal beams 221 on both sides, wherein a plurality of C-shaped steels 223 are provided and are respectively fixed on the two second longitudinal beams 221, wherein the C-shaped steel 223 is located on the side away from the cross beam 222, and the other end of the C-shaped steel 223 is fixed on the side wall of the supporting leg 212. In this embodiment, six C-shaped steels 223 are provided and are evenly installed on the two second longitudinal beams 221.
[0034] In order to realize the lifting of the carrier 1, in this embodiment, Figure 2 and Figure 4 As shown, the supporting assembly 22 is installed between the supporting leg assemblies 21 on both sides, and a gap is left between the supporting assembly 22 and the supporting frame 1, wherein it includes a lifting assembly, one end of the lifting assembly is installed on the supporting assembly 22, and the other end is installed on the supporting frame 1.
[0035] Specifically, in this embodiment, if Figure 4 and Figure 5 As shown, the lifting assembly adopts an electric push rod 3, wherein four groups of electric push rods 3 are provided, and the four electric push rods 3 are distributed in a rectangular shape, one end of the electric push rod 3 is fixedly mounted on the second longitudinal beam 221, and the other end of the electric push rod 3 is fixedly mounted on the bottom wall of the carrier frame 1.
[0036] Through the above arrangement, when the support frame 1 needs to be raised or lowered, the electric push rods 3 are energized, and the synchronous extension or retraction of the telescopic rods of the four electric push rods 3 is controlled, so that the height of the support frame 1 can be adjusted, thereby realizing the height adjustment of the apartment bed.
[0037] When there is a gap between the first longitudinal beam 211 of the support frame 1 and the support part 2, the weight of the support frame 1 and the tenant lying on the support frame 1 will be transferred to the telescopic rods of the four electric push rods 3. When the tenant flips over on the apartment bed, the support frame 1 will shake, which may easily cause damage to the electric push rods 3.
[0038] In order to avoid the problem of the support frame 1 shaking left and right after it is raised, in this embodiment, Figure 2 , Figure 5 and Figure 6 As shown, a plurality of groups of positioning tube groups extending vertically downward are fixedly provided on the supporting frame 1, wherein each group of positioning tube groups includes two guide tubes 11, and the guide tubes 11 are square tubes or steel tubes with circular cross-sections. The guide tubes 11 are welded to the supporting frame 1, and the two guide tubes 11 in the same positioning tube group are clamped on both sides of the second longitudinal beam 221, and the side walls of the guide tubes 11 are abutted against the side walls of the second longitudinal beam 221.
[0039] Through the above-mentioned arrangement, when the electric push rod 3 pushes the supporting frame 1 to move up or down, the side wall of the guide tube 11 slides relative to the side wall of the second longitudinal beam 221, thereby playing a guiding role in the lifting process of the supporting frame 1. When the supporting frame 1 tends to swing left and right, the guide tube 11 transmits the lateral force of the supporting frame 1 to the second longitudinal beam 221. At this time, the supporting part 2 limits the shaking of the supporting frame 1, thereby improving the stability of the supporting frame 1.
[0040] After the lifting of the support frame 1 is completed, in order to prevent the gravity of the support frame 1 and the tenant from being directly applied to the telescopic rod of the electric push rod 3 and to prevent the electric push rod 3 from being damaged due to excessive force, in this embodiment, Figure 2 and Figure 3 As shown, a protective component 4 for supporting the carrier frame 1 is also provided between the carrier frame 1 and the support portion 2. Specifically, the protective component 4 includes a first protective structure 41 and a second protective structure 42. The first protective structure 41 is fixedly mounted on the bottom wall of the carrier frame 1 and extends vertically downward, and one end of the second protective structure 42 is rotatably mounted on the support portion 2. The first protective structure 41 is provided with a plurality of first protective teeth 412, and the second protective structure 42 is provided with a plurality of second protective teeth 422. It also includes a pushing mechanism for pushing the second protective structure 42 toward one side of the first protective structure 41 so that the first protective teeth 412 and the second protective teeth 422 are locked with each other.
[0041] Specifically, Figure 3 As shown, the second protective structure 42 is rotatably installed in the inner cavity of the support leg 212 through the pin 424, wherein the pin 424 is installed at the bottom end of the second protective structure 42, and the first protective structure 41 extends through the first longitudinal beam 211 to the inner cavity of the support leg 212. When the electric push rod 3 stops lifting the support frame 1, the first protective teeth 412 and the second protective teeth 422 engage with each other. At this time, the gravity on the support frame 1 is transmitted to the second protective structure 42 through the first protective structure 41 and the force is dispersed to the support leg 212 through the pin 424, thereby reducing the pressure on the electric push rod 3 and protecting the electric push rod 3.
[0042] In this embodiment, the first protective structure 41 includes a first protective plate 411 extending vertically downward, the first protective plate 411 is inserted into the inner cavity of the supporting leg 212, and the side wall of the first protective plate 411 abuts against the side wall of the inner cavity of the supporting leg 212 to ensure the stable lifting of the carrier 1, wherein a plurality of first protective teeth 412 are provided and are arranged in sequence along the length direction of the first protective plate 411, and the first protective teeth 412 include a first locking surface 4121 arranged horizontally and a first guiding inclined surface 4122 in an inclined state; the second protective structure 42 includes a second protective plate 421, wherein a plurality of second protective teeth 422 are arranged along the length direction of the first protective plate 411 The second protective teeth 422 are distributed in sequence along the length direction of the second protective plate 421. The second protective teeth 422 include a horizontally arranged second locking surface 4221 and an inclined second guiding inclined surface 4222. When the electric push rod 3 stops lifting, the pushing mechanism pushes the second protective structure 42 to rotate around the latch 424, so that the second protective structure 42 is inclined toward the first protective structure 41, so that the first locking surface 4121 of the first protective tooth 412 is in contact with the second locking surface 4221 of the second protective tooth 422, thereby forming a buckling engagement between the first protective tooth 412 and the second protective tooth 422, and then the first protective structure 41 can prevent the carrier 1 from falling downward.
[0043] When the electric push rod 3 pushes the supporting frame 1 upward, as the supporting frame 1 moves upward, it can drive the first protective structure 41 to move upward. At this time, the first guiding inclined surface 4122 on the first protective tooth 412 abuts against the second guiding inclined surface 4222 on the second protective tooth 422, and then the second protective plate 421 is flipped around the pin 424 to the side away from the first protective plate 411, and the pushing mechanism is pushed to slide away from the supporting leg 212. When the supporting frame 1 rises to the vertical height of the first protective tooth 412, the pushing mechanism continues to push the second protective plate 421, and the first locking surface 4121 of the first protective tooth 412 abuts against the second locking surface 4221 of the second protective tooth 422 again.
[0044] In this embodiment, if Figure 3 and Figure 5 As shown, the pushing mechanism includes a traction block 43, a push rod 431, a slider 432, a guide groove 423 and a spring 44, wherein the opening of the C-shaped steel 223 is upward, the traction block 43 is installed in the groove of the C-shaped steel 223, and the traction block 43 can slide along the length direction of the C-shaped steel 223, the guide groove 423 is arranged on the second protective plate 421 and along the length direction of the second protective plate 421, the slider 432 is slidably installed with the guide groove 423, one end of the push rod 431 is fixedly connected to the traction block 43, and the other end of the push rod 431 is rotatably connected to the slider 432, and the spring 44 is installed between the traction block 43 and the second longitudinal beam 221, the first end of the spring 44 abuts against the side wall of the second longitudinal beam 221, and the second end of the spring 44 abuts against the traction block 43.
[0045] Specifically, in the present embodiment, the spring 44 is a compression spring. In the free state, the spring 44 pushes the traction block 43, so that the traction block 43 tends to move toward the second protective plate 421, thereby enabling the second protective teeth 422 to always be engaged with the first protective teeth 412, thereby preventing the support frame 1 from applying all gravity to the electric push rod 3.
[0046] With the above arrangement, when the electric push rod 3 pushes the carrier 1 upward, the second protective plate 421 tends to flip around the pin 424 to the side away from the first protective plate 411, and the guide groove 423 and the slider 432 slide relative to each other. The slider 432 pushes the traction block 43 toward the second longitudinal beam 221 through the push rod 431, and then continues to compress the spring 44. When the carrier 1 stops moving upward, the elastic force in the spring 44 acts on the traction block 43 again, and pushes the second protective plate 421 toward the first protective plate 411 through the push rod 431, so that the first protective teeth 412 and the second protective teeth 422 are re-engaged to share the gravity of the carrier 1, thereby protecting the electric push rod 3.
[0047] When it is necessary to lower the height of the carrier frame 1, the pushing mechanism needs to drive the second protective plate 421 to flip around the pin 424 to the side away from the first protective plate 411, so that the first locking surface 4121 of the first protective tooth 412 and the second locking surface 4221 of the second protective tooth 422 are disengaged, and then the telescopic rod of the electric push rod 3 contracts inward, thereby being able to lower the height of the carrier frame 1. When the height of the carrier frame 1 is adjusted to an appropriate position, the restriction on the pushing mechanism is released, so that the first protective tooth 412 and the second protective tooth 422 are re-engaged, thereby completing the downward movement of the carrier frame 1.
[0048] In this embodiment, in order to improve the gravity dispersion effect of the support frame 1 , six groups of protection components 4 are provided and are respectively installed in six supporting legs 212 .
[0049] In order to facilitate the release of the pushing mechanism on the second protective plate 421 and complete the downward movement of the support frame 1, in this embodiment, the three traction blocks 43 on the same side are fixed by a synchronization plate 433. When the support frame 1 needs to be adjusted downward, it is only necessary to move the synchronization plate 433 to drive the traction block 43 to move, thereby releasing the pushing of the second protective plate 421.
[0050] It also includes an unlocking component 5 for releasing the pushing mechanism from pushing the second protective plate 421, such as Figure 2 , Figure 5 and Figure 7As shown, the unlocking assembly 5 includes an unlocking rack 51, an unlocking gear 52 and a transmission rod 53. Specifically, two unlocking racks 51 are provided, and the two unlocking racks 51 are respectively fixedly mounted on the synchronization plates 433 on both sides, and the teeth of the unlocking racks 51 are arranged opposite to each other. The unlocking gear 52 is also meshed with the teeth of the unlocking rack 51, and the transmission rod 53 is fixedly mounted on the unlocking gear 52 and extends to one side of the foot of the apartment bed.
[0051] Through the above arrangement, the transmission rod 53 is used to drive the unlocking gear 52 to rotate, and then drive the unlocking rack 51 to move in the opposite direction, at this time driving the synchronous plates 433 on both sides to move toward the second longitudinal beam 221 and compress the spring 44, thereby driving the traction block 43, the push rod 431 and the slider 432 to move, so that the second protective plate 421 moves away from the first protective plate 411, so that the first protective teeth 412 and the second protective teeth 422 of the six groups of protective components 4 are released at the same time, thereby increasing the speed of the downward movement of the carrier frame 1.
[0052] Specifically, in this embodiment, if Figure 2 and Figure 5 As shown, the unlocking rack 51 is fixedly mounted on the traction block 43 at the middle position, and the unlocking rack 51 is received in the inner cavity of the middle cross beam 222 .
[0053] A handle 54 is provided at one end of the transmission rod 53 located at the foot of the apartment bed, which is convenient for rotating the transmission rod 53. When the height of the carrier frame 1 is adjusted, the restriction on the handle 54 is released. At this time, the spring 44 will push the traction block 43 to move, and the push rod 431 completes the pushing of the second protective plate 421, while driving the unlocking rack 51 to reset.
[0054] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
