[0046] Embodiment one
[0047] Please refer to Figures 1 to 9 The damping bed leg 100 provided in the embodiments of the present application is installed on a bed frame (not shown in the drawings) to achieve the effect of damping and noise reduction. The damping bed leg 100 comprises an outer sleeve 1, an inner sleeve 2, an elastic damping piece and a guiding anti-off assembly 4.
[0048] The outer sleeve 1 comprises a bottom plate 11 and a first peripheral wall 12. The bottom plate 11 and the first peripheral wall 12 enclose a first sleeve cavity a, and the upper end of the first sleeve cavity a is open. Optionally, in the present embodiment, the outer sleeve 1 is a cylindrical sleeve structure, and of course in other embodiments, the outer sleeve 1 can also be a sleeve structure of other shapes, which is not specifically limited here. The lower end of the outer sleeve 1 contacts a support surface (not shown in the drawings).
[0049] The inner sleeve 2 comprises a top plate 21 and a second peripheral wall 25. The top plate 21 and the second peripheral wall 25 enclose a second sleeve cavity e, the lower end of which is open. The inner sleeve 2 is at least partially sleeved in the outer sleeve 1 and can extend and retract relative to the outer sleeve 1. The upper end of the inner sleeve 2 is used to connect to a bed frame. Specifically, a threaded rod 22 can be provided at the upper end of the inner sleeve 2 to be screwed into a threaded hole on the bed frame.
[0050] The elastic damping member is arranged in the cavity g between the inner sleeve 2 and the outer sleeve 1, and one end of the elastic damping member abuts against the outer sleeve 1 and the other end abuts against the inner sleeve 2. Since the elastic damping member is arranged in the cavity g between the inner sleeve 2 and the outer sleeve 1, the elastic damping member is not easily damaged.
[0051] Thus, when the inner sleeve 2 is subjected to an external force, for example, when a massage vibrator (not shown in the figure) of an electric bed (not shown in the figure) is turned on to perform a massage function, the elastic damping member can absorb and relieve the vibration energy through compression and recovery, thereby achieving the effects of damping and noise reduction.
[0052] The guiding and anti-disengagement assembly 4 comprises a plurality of outwardly protruding elastic buckles 41 and a clamping groove c. The plurality of outwardly protruding elastic buckles 41 are arranged on the outer wall of the inner sleeve 2. The clamping groove c is vertically extended and arranged on the inner wall of the outer sleeve 1 in correspondence with the elastic buckles 41. The clamping groove c has a clamping opening d, and there is a vertical spacing between the clamping opening d and the sleeve opening b of the outer sleeve 1.
[0053] Thus, during the compression stroke of the elastic damping member, the inner sleeve 2 can stably descend along the clamping groove c, and during the expansion stroke of the elastic damping member, the inner sleeve 2 can stably ascend along the clamping groove c, and the position of the clamping opening d can prevent the inner sleeve 2 from disengaging from the outer sleeve 1. Thus, the inner sleeve 2 has the advantages of stability and anti-disengagement function.
[0054] Optionally, please refer to Figure 3 , Figures 6 to 9 In this embodiment, the bottom plate 11 of the outer sleeve 1 is provided with a first guiding inner sleeve 13 which is concentric with the sleeve wall of the outer sleeve 1 and extends upward. The top plate 21 of the inner sleeve 2 is provided with a second guiding inner sleeve 23 which is concentric with the sleeve wall of the inner sleeve 2 and extends downward. The elastic damping member is a compression spring 3 which is sleeved outside the first guiding inner sleeve 13 and the second guiding inner sleeve 23. Thus, the elastic damping member can be further prevented from being laterally deviated during deformation. It can be understood that, in this embodiment, the outer diameter of the first guiding inner sleeve 13 is equal to the outer diameter of the second guiding inner sleeve 23, and the height of the first guiding inner sleeve 13 plus the height of the second guiding inner sleeve 23 is less than the height of the cavity g formed by the inner sleeve 2 and the outer sleeve 1 during the maximum compression stroke of the damping bed leg 100, so as to avoid interference.
[0055] Optionally, please refer to Figure 3 and Figure 8In this embodiment, the inner sleeve 2 is further provided with several connecting ribs 24 connecting the second guide inner cylinder 23 and the inner peripheral wall 12; one end of the compression spring 3 abuts against the bottom plate 11 of the outer sleeve 1, and the other end abuts against the connecting ribs 24 of the inner sleeve 2. Specifically, in this embodiment, the top of the connecting ribs 24 is connected to the top plate 21 of the inner cylinder, and the lower ends of the several connecting ribs 24 form an abutting surface for the compression spring 3 to abut against. It can be understood that the abutting surface formed by the lower ends of the several connecting ribs 24 does not reach the lower end of the second guide inner cylinder 23 of the inner sleeve 2 in the vertical direction, so as to facilitate the sleeve of the compression spring 3.
[0056] To prevent the compression spring 3 from damaging the outer sleeve 1 and / or the inner sleeve 2 during repeated compression and recovery, optionally, please refer to... Figure 3 , Figure 6 and Figure 7 In this embodiment, gaskets 5 are provided between the compression spring 3 and the bottom plate 11 of the outer sleeve 1, and between the compression spring 3 and the connecting rib plate 24 of the inner sleeve 2. Optionally, the gaskets 5 are metal gaskets 5.
[0057] To prevent the compression springs 3 of the shock-absorbing bed legs 100 from being damaged by overload, it has been tested that, optionally, in this embodiment, the load-bearing capacity of a single compression spring 3 is greater than or equal to 200 kg. Thus, the compression springs 3 of the four shock-absorbing bed legs 100 can support a weight of over 800 kg, thereby preventing damage to the compression springs 3 due to overload.
[0058] To make the shock absorption stroke of the shock-absorbing bed leg 100 more balanced, optionally, please refer to... Figure 8 and Figure 9 In this embodiment, four protruding elastic buckles 41 are arranged in a circumferential array on the outer wall of the inner sleeve 2, and four corresponding slots c are arranged in a circumferential array on the inner wall of the outer sleeve 1. Of course, in other embodiments, the number of elastic buckles 41 and slots c can be three, five, six, or other numbers, and there is no specific limitation.
[0059] For easier demolding, please refer to the following: Figure 8 and Figure 9 In this embodiment, the end of the slot c away from the slot d passes through the bottom plate 11 of the outer sleeve 1.
[0060] To reduce vibration and wear during the relative movement of the inner sleeve 2 and the outer sleeve 1, optionally, please refer to... Figure 7 In this embodiment, a felt sleeve 6 is fitted around the outer periphery of the inner sleeve 2.
[0061] Alternatively, please refer to Figure 3 and Figure 7 In this embodiment, a shock-absorbing silicone pad 7 is fixed to the bottom of the outer sleeve 1. This further enhances the shock absorption effect of the shock-absorbing bed leg 100.
[0062] Example 2
[0063] This embodiment is basically the same as Embodiment 1, except that it implements the connection component with the bed frame or supporting plane. That is, the end of the outer sleeve 1 of the shock-absorbing bed leg 100 away from the inner sleeve 2 is used to connect to the bed frame, and the end of the inner sleeve 2 away from the outer sleeve 1 contacts the supporting surface.
[0064] Example 3
[0065] Another aspect of this utility model embodiment provides a bed frame (not shown in the figure), including a bed frame and a shock-absorbing bed leg 100 as described above, one end of which is fixed to the bed frame by a screw 22. Since this bed frame has all the structure and connection relationships of the shock-absorbing bed leg 100, it has all the advantages of the shock-absorbing bed leg 100, which will not be elaborated here.
[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
