Description

Technical Field

[0001] The utility model relates to a bed, in particular to a bed with adjustable legs. Background Art

[0002] At present, in the bed structure, it is necessary to install bed legs at the four corners of the lower side of the bed to support the entire bed. The existing bed legs are generally fixedly installed on the bed frame. When the height needs to be adjusted, it is very inconvenient to add something under the bed legs. Setting the bed legs to be detachable can meet the needs of transportation and packaging, but it also does not solve the problem of how to adjust the length of the bed legs.

[0003] In order to solve the problem of bed leg length, it is now considered to design the bed leg into a segmented structure to meet this demand, such as an adjustable bed leg mentioned in patent CN214127777U, an adjustable bed leg mentioned in patent CN114947447A, an adjustable bed leg mentioned in patent CN217447192U, and so on.

[0004] In the above patents, the bed legs are designed to be divided into multiple sections. When the height of the bed legs needs to be increased, a corresponding number of sections are added. When the height of the bed legs needs to be lowered, a corresponding number of sections are removed. Regardless of adding sections or removing sections, the bed legs need to be removed from the bed first, and then adjusted, which is very troublesome. In addition, during processing, it is necessary to ensure the accuracy of the upper and lower end surfaces of each section, otherwise, when the sections are connected, it is possible that the sections cannot be connected, or the bed legs may be tilted after being installed, which will affect the smooth use of the bed legs.

[0027] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0028] like Figure 1-Figure 4 An adjustable bed foot is shown, comprising an inner bed foot tube and an outer bed foot tube formed by inner and outer connection.

[0029] The outer tube of the bed foot includes a hollow cylindrical outer tube body 1, and an inner lining sheet 11 is connected to the inner wall of the outer tube body 1 on the side away from the inner tube of the bed foot. The inner lining sheet 11 is directly welded and fixed to the inner wall of the outer tube body 1, and a connecting screw 12 extending outside the outer tube body is connected to the inner lining sheet 11. The connecting screw 12 has an external thread structure for connecting to a bed frame or a bed body, and an adjustment groove is also opened on the outer wall of the outer tube body 1. The adjustment groove includes a movable groove 13 extending along the axial direction of the outer tube body 1 and several positioning grooves 14 distributed on the same side of the movable groove 13 along the axial direction of the outer tube body 1, and each positioning groove 14 is connected to the movable groove 13 through a horizontally arranged connecting groove 15. The top height of the positioning groove 14 is higher than the top height of the connecting groove 15. The control of this height can prevent the positioning pin 21 from slipping arbitrarily after being inserted into the positioning groove 14, thereby fixing the positioning pin 21.

[0030] The positioning groove 14 is a waist-shaped groove, and the long axis direction of the waist-shaped groove is parallel to the axial direction of the outer tube body 1, and the connecting groove 15 is connected to the middle position of the waist-shaped groove.

[0031] The inner tube of the bed foot comprises a hollow cylindrical inner tube body 2. A positioning pin 21 is inserted into the adjustment groove and moves back and forth between the movable groove 13 and the positioning groove 14.

[0032] There are two adjustment slots, which are located on both sides of the outer tube body 1, and two positioning pins 21 are respectively inserted into the two adjustment slots on the inner tube of the foot. The two adjustment slots and the two positioning pins 21 are used in a coordinated manner, so that the support is more stable during and after adjustment, avoiding the phenomenon of unilateral tilt.

[0033] When there are two positioning pins 21, there are two different structural forms:

[0034] like Figure 2 As shown in the schematic diagram, the first structural form of the two positioning pins 21 is: the two positioning pins 21 are formed by a pin shaft 22 horizontally penetrating the inner tube body 2, and a through hole for the pin shaft 22 to pass through is opened on the inner tube body 2. After the pin shaft 22 passes through the through hole on the inner tube body 2, the two sides of the pin shaft 22 extend out of the pin shaft 22 respectively, thereby serving as the required positioning pin 21. The positioning pin 21 formed in this way is directly in the form of a pin shaft 22, which is easy to process.

[0035] like Figure 3As shown in the schematic diagram, the second structural form of the two positioning pins 21 is: the two positioning pins 21 are connected by a U-shaped spring 23, the U-shaped spring 23 is placed in the cavity of the inner tube body 2, and the two sides of the U-shaped spring 23 are respectively against the inner walls of the inner tube body 2. This form of positioning pin 21 utilizes the elastic effect of the U-shaped spring 23 to keep the positioning pin 21 in a fixed position, thereby preventing the positioning pin 21 from moving back and forth during use.

[0036] An inner sleeve 24 is also provided on one side of the inner tube body 2 close to the outer tube of the foot of the bed. Figure 4 As can be seen from the schematic diagram shown, the inner sleeve 24 includes an insert section 241 inserted into the inner tube body 2 and a retaining section extending out of the inner tube body. The insert section 241 is in the shape of a circular tube, and the retaining section is composed of a plurality of tooth-shaped structures 242 distributed along the circumferential direction of the insert section 241 and extending horizontally outward. A gap is left between two adjacent tooth-shaped structures 242, and the outer contour lines of each tooth-shaped structure 242 are on the same circle, and the outer wall of each tooth-shaped structure 242 fits with the inner wall of the outer tube body 1. The design of the inner sleeve 24 on the inner tube body 2 is to maintain the relative position between the inner tube body 2 and the outer tube body 1 through the inner sleeve 24. Since the inner tube body 2 and the outer tube body 1 need to be slidably matched, it is inevitable that there will be a gap between the inner tube body 2 and the outer tube body 1. Therefore, the inner sleeve 24 is provided to avoid the shaking of the inner tube body 2 caused by the gap between the inner tube body 2 and the outer tube body 1, thereby ensuring the normal use of the entire bed leg.

[0037] The upper end surface of the toothed structure 242 is also provided with a guiding slope. The design of the guiding slope plays a guiding role when the inner tube body 2 is inserted into the outer tube body 1, ensuring that the inner liner tube 24 can be smoothly inserted into the outer tube body 1.

[0038] A foot cover 25 is also mounted on the bottom of the inner tube body 2. The foot cover 25 is designed to protect the inner tube body 2, thereby preventing the inner tube body 2 from directly contacting the ground and rubbing against each other to cause wear.

[0039] When the bed foot of the utility model is used, firstly, the corresponding positioning pin 21 is selected according to the initial height requirement and inserted into the corresponding positioning groove 14, and then the bed foot is fixed to the bed frame or bed body by the cooperation of the connecting screw 12;

[0040] During subsequent use, when the height of the bed legs needs to be adjusted, the bed frame is lifted, which in turn drives the bed legs upward so that the bed legs are off the ground, and then the inner tube body 2 is operated so that the positioning pin 21 moves up and down in the positioning groove 14, and when the positioning pin 21 moves to the connecting groove 15, the inner tube body 2 is rotated so that the positioning pin 21 slides from the positioning groove 14 to the movable groove 13, and then the inner tube body 2 is operated so that the positioning pin 21 slides up and down in the movable groove 13. When the positioning pin 21 slides to the positioning groove 14 of the specified height, the inner tube body 2 is rotated so that the positioning pin 21 slides through the connecting groove 15 into the corresponding positioning groove 14. At this time, the bed frame can be lowered to complete the height adjustment.

[0041] In the present invention, in addition to using two adjustment slots to adjust the height of the bed foot, another structure can also be used to achieve it, such as Figure 5 , Figure 6 As shown, there is one adjustment groove on the outer wall of the outer tube body 1, which is located on one side of the outer tube body 1, and a fixing groove is also provided on the outer wall of the other side of the outer tube body 1. The fixing groove is composed of a number of fixing holes 17 distributed on the outer wall of the outer tube body 1 from top to bottom. The fixing holes 17 are circular through holes, and each fixing hole 17 corresponds to each positioning groove 14 one by one. A butterfly screw 18 is also provided on the inner tube body 2 to match the fixing hole 17. The butterfly screw 18 passes through the fixing hole 17 horizontally from outside to inside and is threadedly fixed to the inner tube body 2. A threaded through hole matching the butterfly screw 18 is opened on the inner tube body 2. The matching of the outer tube body 1 and the inner tube body 2 is achieved by adopting a method of one side being an adjustment groove and the other side being a fixing groove, and the fixing of the butterfly screw 18 is coordinated, so that the purpose of adjustment can be achieved, and the stability of the adjusted bed foot is higher, and the occurrence of undesirable phenomena such as shaking can be reduced.
