Description

Technical Field

[0001] This utility model relates to the field of home technology, specifically, to an adjustable bed leg structure. Background Technology

[0002] Modern beds typically have four legs to support the entire bed frame, and these legs can be removed.

[0003] On June 16, 2022, the applicant filed an application for an adjustable bed leg, with authorization publication number CN217447192U. This bed leg is composed of several bed leg segments that are detachably assembled sequentially along the axial direction. The bed leg segments are made of metal. Each bed leg segment has a connecting rod, which is divided into upper and lower parts. The lower part of the connecting rod is fixedly connected to the upper end of the bed leg segment, and the upper part is detachably inserted into the lower end of the previous bed leg segment. The upper part of the connecting rod of the highest-positioned bed leg segment is detachably inserted into the bed frame. However, the adjustment method disclosed in this patent is inconvenient and costly.

[0004] In addition, another patent, authorized publication number CN214631188U, discloses an adjustable bed with a height-adjustable bed leg assembly under the bed frame. The bed leg assembly includes a fixed base fixed to the bed frame and an adjusting member slidably connected to the fixed base. The adjusting member slides axially relative to the fixed base to adjust the height of the bed leg assembly. This patent uses a pin locking method to lock the adjusted bed legs, and requires manual operation of two pins to fix them, which is relatively cumbersome. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable bed leg structure to solve the problems existing in the prior art.

[0006] The purpose of this utility model is achieved as follows: an adjustable bed leg structure, comprising:

[0007] The upper cylinder is connected to the bed and has multiple locking holes spaced vertically and corresponding to different locking positions.

[0008] The lower cylinder is used to support the ground, and the upper cylinder can be adjusted up and down to fit onto the lower cylinder;

[0009] An elastic locking mechanism includes an elastic element installed in the lower cylinder and a stop pin connected to the elastic element, the stop pin extending outward through a locking hole disposed in the side wall of the lower cylinder.

[0010] When adjusting the height of the bed legs, the locking hole is selectively aligned with the locking hole of the corresponding locking position, so that the stop pin is driven by the elastic element to insert outward into the locking hole of the corresponding locking position to lock the height of the bed legs.

[0011] Furthermore, the upper cylinder is provided with a guide structure corresponding to the locking hole position. The guide structure extends in the vertical direction, and when the height of the bed legs is adjusted, the stop pin slides with the guide structure.

[0012] Furthermore, the lower cylinder sidewall is provided with several gear position markings arranged along its axial direction, each gear position marking corresponding to a locking position, and the lower end of the upper cylinder is directly opposite the gear position marking of the corresponding locking position in the locked state.

[0013] Furthermore, the elastic element of the elastic locking mechanism is a sheet-like spring, which is driven by its elastic force to abut against the inner wall of the lower cylinder.

[0014] Furthermore, the spring is a bent plate, and the elastic extension and retraction direction of the spring conforms to the insertion direction of the stop pin.

[0015] Furthermore, the locking holes are divided into several pairs and arranged at intervals from top to bottom. Each pair of locking holes is distributed left and right. There is one pair of locking holes and one pair of stop pins, which are respectively inserted into the two locking holes. In the locked state, the two stop pins are driven by the elastic element to insert into one pair of locking holes.

[0016] Furthermore, the upper cylinder has two guide holes distributed on the left and right sides, the guide holes forming the guide structure, and the guide holes are connected in series with all the locking holes on the same side.

[0017] Furthermore, the gear position marking part includes a gear position marking hole opened on the side wall of the lower cylinder, and a gear position indicator hole is provided at the lower end of the upper cylinder. In the locked state, the gear position indicator hole at the lower end of the upper cylinder is directly opposite the gear position marking hole of the corresponding locked gear.

[0018] Furthermore, the stop pin is cylindrical, and the width of the guide hole is smaller than the diameter of the stop pin.

[0019] Furthermore, the end of the stop pin is rounded or chamfered. When adjusting the height of the bed legs, the end of the stop pin abuts against the guide hole from inside the upper cylinder and slides with the guide hole.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. During the entire adjustment process, the stop pin will not come off, and there will be no phenomenon of the stop pin slipping out or the upper and lower cylinders separating.

[0022] 2. During the adjustment process, users can clearly see the position of the stop pin and clearly observe the adjustment level, resulting in higher adjustment efficiency and accuracy;

[0023] 3. The number of locking holes can be flexibly set according to needs, and the adjustment level can be set arbitrarily. Compared with the solution of using multi-section bed legs for height adjustment, it is more convenient and lower in cost. Attached Figure Description

[0036] The following will refer to the appendix in the embodiments of this utility model. Figure 1-12 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0037] Example 1

[0038] like Figure 1-5 As shown, an adjustable bed leg structure is proposed, mainly including:

[0039] The upper cylinder 1 is connected to the bed. The upper cylinder 1 has multiple locking holes 1a that are spaced apart vertically and correspond to different locking positions. The upper cylinder 1 can be a cylinder or other structural options, which are not limited here.

[0040] The lower cylinder 2 is used to support the ground. The diameter of the lower cylinder 2 is smaller than that of the upper cylinder 1. The upper cylinder 1 can be adjusted up and down to fit the lower cylinder 2. The lower cylinder 2 can be a cylinder or other structural options, which are not limited here.

[0041] The elastic locking mechanism 3 includes an elastic element installed inside the lower cylinder 2 and a stop pin 3b connected to the elastic element. The stop pin 3b extends outward through a locking hole 2a on the side wall of the lower cylinder 2.

[0042] When adjusting the height of the bed legs, the locking hole 2a is selectively aligned with the locking hole 1a of the corresponding locking position, so that the stop pin 3b is driven by the elastic element to insert outward into the locking hole 1a of the corresponding locking position, thereby locking the height of the bed legs, that is, locking the relative position of the upper cylinder 1 and the lower cylinder 2.

[0043] As a standard feature, a top plate 4 is fixedly connected to the upper part of the inner wall of the upper cylinder 1. An upper connecting pin 5 is fixedly inserted into the top plate 4. The upper connecting pin 5 extends upward beyond the upper end of the upper cylinder 1 and is used to quickly connect with the bed.

[0044] The upper cylinder 1 is provided with a guide structure corresponding to the locking hole 1a. The guide structure extends in the vertical direction. When adjusting the height of the bed legs, the stop pin 3b slides with the guide structure. It is worth mentioning that the guide structure can have a variety of structural options, such as a guide hole or guide groove, or other guide structures.

[0045] To facilitate locking the position of the upper cylinder 1 relative to the lower cylinder 2, and thus to facilitate locking the height (also known as the length) of the bed legs, the structural scheme of this embodiment is as follows (but not limited to the following methods):

[0046] like Figure 2As shown, the upper cylinder 1 has several pairs of locking holes 1a spaced vertically and corresponding to different locking positions. This means that the locking holes 1a can be divided into two groups, left and right. Each pair of locking holes 1a is symmetrically distributed left and right. The lower cylinder 2 has a pair of locking holes 2a symmetrically distributed left and right. The elastic locking mechanism 3 includes a spring 3a and a pair of stop pins 3b fixedly connected to the left and right sides of the spring 3a respectively. Using the elastic force of the spring 3a, the pair of stop pins 3b are driven to insert into the two locking holes 2a radially. The spring 3a is driven by its elastic force to abut against the inner wall of the lower cylinder 2 radially, thereby fixing the entire elastic locking mechanism 3 in the lower cylinder 2.

[0047] In this embodiment, the elastic element of the elastic locking mechanism 3 is a sheet-like spring plate 3a (or other elastic structure). The spring plate 3a is a bent plate, and the elastic extension and retraction direction of the spring plate 3a follows the insertion direction of the stop pin 3b. The spring plate 3a shown in this embodiment is a V-shaped plate with the opening facing upward. It is worth noting that the spring plate 3a can be a spring plate structure of other shapes.

[0048] like Figure 6-10 As shown, the above-mentioned guide structure is provided with two guide holes 1b distributed on the left and right. The two guide holes 1b correspond to the two sets of locking holes 1a on the left and right respectively. Each guide hole 1b is connected in series with all the locking holes 1a in the corresponding set. The guide hole 1b is a strip-shaped hole and is parallel to the axial direction of the upper cylinder 1. The guide hole 1b is connected to all the locking holes 1a on the same side to form an irregular hole, which is convenient for manufacturing.

[0049] The stop pin 3b is cylindrical. The width of the guide hole 1b is smaller than the diameter of the stop pin 3b, while the inner diameter of the locking hole 1a and the locking hole 2a is larger than the diameter of the stop pin 3b. This ensures that the stop pin 3b will not slide out of the guide hole 1b during adjustment and will not slide out when locked. The end of the stop pin 3b is rounded. When adjusting the height of the bed legs, the end of the stop pin 3b abuts against the guide hole 1b from inside the upper cylinder 1 and slides in cooperation with the guide hole 1b. Therefore, during the adjustment process, the guide hole 1b acts as a guide rail, accurately guiding the stop pin 3b to slide to the predetermined locking hole 1a, which greatly facilitates the adjustment and locking operation of the bed legs.

[0050] In the locked state, that is, when the height of the bed legs needs to be locked, the locking hole 2a of the lower cylinder 2 is aligned with the two locking holes 1a of one of the locking positions, and the stop pin 3b is driven by the elastic force of the elastic element to insert into the locking hole 1a of the corresponding position.

[0051] In the adjustment state, that is, when the height of the bed legs needs to be adjusted, when the position needs to be adjusted, simply press down the stop pin 3b, so that the stop pin 3b part disengages from the locking hole 1a on the upper cylinder 1. By rotating or pushing and pulling the lower cylinder 2, the round head of the stop pin 3b can move within the guide hole 1b (e.g., Figure 9-10As shown), when the position to be adjusted is reached, the stop pin 3b is inserted into the corresponding locking hole 1a to complete the locking operation of the upper and lower cylinders, and the adjustment is completed.

[0052] In summary, this solution has the following advantages:

[0053] 1. During the entire adjustment process, the stop pin 3b will not disengage from the guide hole 1b, and there will be no phenomenon of the stop pin 3b sliding out or the upper and lower cylinders separating.

[0054] 2. During the adjustment process, the position of the stop pin 3b can be seen through the guide hole 1b, resulting in higher adjustment efficiency and accuracy;

[0055] 3. The number of locking holes 1a can be set according to project requirements, and the adjustment level can be set at will. Compared with the solution of using multi-section bed legs for height adjustment, it is more convenient and lower in cost.

[0056] Example 2

[0057] like Figure 11-12 As shown, the difference between Example 2 and Example 1 is that:

[0058] The upper cylinder 1 does not have guide holes connected to the locking holes. The locking holes 1a are relatively independent. The outer side wall of the lower cylinder 2 is provided with several gear markings arranged along its axial direction (which can be directly seen from the outside for operation). Each gear marking corresponds to a locking position. The lower end of the upper cylinder 1 is directly opposite the gear marking of the corresponding locking position when locked.

[0059] More specifically, each gear position indicator includes a gear position indicator hole 2b opened on the side wall of the lower cylinder 2 and a corresponding number mark on the gear position indicator hole 2b. The number mark can be a hollow hole in the shape of a corresponding number. For example, if there are five gear positions, the numbers 5, 4, 3, 2, and 1 are marked from top to bottom to correspond to the five gear positions and the five gear position indicator holes 2b respectively. The lower end of the upper cylinder 1 is provided with a gear position indicator hole 1c. In the locked state, the gear position indicator hole 1c at the lower end of the upper cylinder 1 is directly opposite the gear position indicator hole 2b of the corresponding locked position. The user can clearly see the gear position indicator hole 1c, the gear position indicator hole 2b, and the corresponding number mark, thereby knowing the adjustment position of the bed leg.

[0060] It is worth noting that the number of gears can be determined according to specific needs and is not limited here; the shape of the gear indicator can also be determined according to specific needs and is not limited here.

[0061] The adjustment principle of Embodiment 2 is similar to that of Embodiment 1, but there are differences: Pressing the stop pin 3b causes it to sink into the upper cylinder 1. At this time, the lower cylinder 2 can move axially along the upper cylinder 1. When the gear marking hole 2b of the lower cylinder 2 coincides with the gear indicator hole 1c on the upper cylinder 1, the stop pin 3b is driven by the elastic force of the spring 3a to pass through the locking hole 1a on the upper cylinder 1, thus completing the gear locking and completing the corresponding gear adjustment.

[0062] The technical advantage of Embodiment Two is that during the adjustment process, the stop pin 3b enters the upper cylinder 1, and the user cannot see the specific position of the stop pin 3b. This often requires judgment based on operational feel, making it difficult to guarantee the efficiency and accuracy of the adjustment operation. With the solution of Embodiment Two, there is no need to focus on the position of the stop pin 3b; adjustment can be completed simply by observing whether the position marking hole 2b of the lower cylinder 2 coincides with the position indicator hole 1c of the upper cylinder 1. This makes adjustment more convenient and accurate.
