Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] This embodiment discloses a soft bed with an adjustable bed support height, referring to... Figures 1-4 The bed mainly includes a bed support 1, a headboard 2, and support legs 3. A hook piece 11 is bolted to the front end of the bed support 1 near the bottom. A hanging piece 21 is bolted to the front end of the headboard 2 at a position matching the hook piece 11 on the bed support 1. The interlocking of the hook piece 11 and the hanging piece 21, with multiple adjustable positions, enables the movable connection between the bed support 1 and the headboard 2. Multiple support legs 3 are fixedly installed at the lower end of the bed support 1. The support legs 3 are connected by a threaded connection where a lower support tube 32 is fitted inside an upper support tube 31, and can be adjusted in multiple stages. The multi-stage adjustment of the hanging piece 21 and the hook piece 11, along with the multi-stage height adjustment of the support legs 31, can be matched to ensure that the bed support 1 remains level after height adjustment.

[0030] Reference Figure 2 As shown, the hanging plate 21 has four hanging holes 22 arranged in sequence along the vertical direction. A raised protrusion (24) is integrally connected to the lower side of each hanging hole 22. A notch 23 is opened in the middle of the protrusion (24). The protrusions 24 on both sides of the notch 23 are arranged symmetrically. The side of the protrusion 24 facing away from the hanging plate 21 forms a clearance gap.

[0031] Two hooks 12 are integrally connected to the surface of the hook piece 11. The hooks 12 are arranged vertically and the distance between the two hooks 12 is consistent with the distance between the two adjacent hook holes 22 on the hook piece 21 to ensure precise engagement. Secondly, a stop block 13 is integrally connected to the end of the hook 12. When the hook piece 11 engages with the hook piece 21, the hook 12 on the hook piece 11 is inserted into the notch 23 on the hook piece 21, so that the stop block 13 is inserted into the hook hole (22) to form a fixed limit.

[0032] A horizontally arranged support part 14 is integrally connected to the lower end of the hook piece 11. When the hook piece 11 is fixedly installed on the bed support 1, the support part 14 on the hook piece 11 can penetrate into the lower end surface of the bed support 1 and support the bed support 1 in the vertical direction, thereby improving the installation stability of the bed support 1.

[0033] Reference Figure 3 and Figure 4 As shown, an inwardly protruding connecting portion 311 is formed on the inner circumference of the lower end of the upper support tube 31, and an internal thread 312 is provided on the inner circumference of the connecting portion 311; multiple external thread segments 321 and multiple blank segments 322 are formed on the outer periphery of the lower support tube 32, and each external thread segment 321 on the lower support tube 32 can cooperate with the internal thread 312 on the inner circumference of the connecting portion 311 to form a threaded connection.

[0034] The external threaded section 321 and the blank section 322 formed around the lower support tube 32 are distributed alternately, and the length of the external threaded section 321 is less than the length of the blank section 322. The purpose is to form a multi-segment height adjustment of the support foot 3. By intermittently setting the blank section 322, the support foot can be quickly adjusted in the vertical direction, thereby improving the adjustment efficiency.

[0035] Since the external thread section 321 on the lower support tube 32 is a protruding external thread, the outer diameter of the external thread section 321 is larger than the outer diameter of the blank section 322. When the lower support tube 32 is threadedly connected to the upper support tube 31, the outer diameter of the protruding external thread section 321 is smaller than the inner diameter of the upper support tube 31. Therefore, the lower support tube 32 can be threadedly connected to the connecting part 311 at the lower end of the upper support tube 31 and fitted inside the upper support tube 31 to achieve height adjustment of the support foot 3. The outer diameter of the blank section 322 is smaller than the inner diameter of the connecting part 311, so the blank section 322 can directly pass through the connecting part 311 to achieve multi-stage rapid height adjustment of the support foot 3.

[0036] like Figure 1 As shown, a mattress 4 is placed horizontally on the upper end of the bed support 1. The height of the bed support 1 can be adjusted to accommodate mattresses 4 of different thicknesses.

[0037] Example 2

[0038] This embodiment discloses a soft bed with an adjustable bed support height, based on Embodiment 1, and further referring to... Figure 4 Please provide a detailed explanation.

[0039] To improve the safety and stability of the support foot 3 during height adjustment, the lower support tube 32 is designed to be vertically continuous and has a movable seat 33 installed on its inner circumference. A buffer spring 34 is fixedly connected to the upper end of the movable seat 33. An internal thread 323 is formed on the inner circumference of the lower support tube 32, and an external thread 331 is formed on the outer circumference of the movable seat 33. Through the mutual cooperation of the external thread 331 and the internal thread 323, the movable seat 33 and the lower support tube 32 are threadedly connected. By adjusting the height of the movable seat 33 inside the lower support tube 32, the contact distance between the buffer spring 34 connected to the upper end of the movable seat 33 and the top end of the upper support tube 31 can be controlled, which can effectively improve the buffering effect of the buffer spring 34.

[0040] The movable seat 33 and the fixedly connected buffer spring 34 are installed from the bottom of the lower support tube 32. A limit groove 332 is provided on the lower end face of the movable seat 33, allowing height adjustment using a tool (such as a screwdriver) that matches the limit groove 332. The buffer spring 34 at the upper end of the movable seat 33 is adjusted to a suitable height, and then the lower support tube 32 is installed into the interior of the upper support tube 31 via a threaded connection. Adjustment is generally performed before the support foot 3 is installed, refer to... Figure 4As shown (the upper end of the buffer spring 34 does not abut against the upper part of the upper support tube 31), it can be raised and moved upward by adjusting the movable seat 33 by thread until the upper end of the buffer spring 34 abuts against the upper part of the upper support tube 31 to form elastic support.

[0041] When the support leg 3 is adjusted from high to low, the lower support tube 32 needs to be rotated inwards towards the upper support tube 31. Under the weight of the bed support 1, when the connection between the lower end of the upper support tube 311 and the lower support tube 32 transitions from the external thread section 321 to the blank section 322, the bed support 1 may drop rapidly. At this time, the buffer spring 34 plays an important buffering role, reducing the impact caused by the rapid drop of the support leg 3 when adjusting from high to low, and improving the safety and stability of the adjustment. The above description is only a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions within the scope of this utility model's concept are within the protection scope of this utility model. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
