Clamping jaw type belleville spring for elastic connection of furniture

Abstract

The utility model relates to the technical field of elastic connecting pieces, in particular to a clamping jaw type belleville spring for elastic connection of furniture, which comprises a belleville spring body with a conical annular structure, one side of the belleville spring body is a small-opening end, the other side of the belleville spring body is a large-opening end, and at least one of the small-opening end and the large-opening end is provided with a radial clamping structure. Compared with the prior art, by arranging the radial clamping structure, one end of the belleville spring can clamp a shaft or other fixing parts when the belleville spring stretches out and draws back, it is kept that the position and direction of the belleville spring are not eccentric, the elastic efficiency can be kept, and the belleville spring is prevented from losing efficacy.

Description

Technical Field

[0001] The utility model relates to the technical field of elastic connecting pieces, in particular to a furniture elastic connecting claw type disc spring. Background Art

[0002] Most existing disc springs are in the shape of ordinary bowls and discs, which are difficult to be fixed in one position in furniture connections. If the inner diameter is larger than the mounting axis, the disc spring will be offset from the center position, causing the disc spring to weaken or even disappear. Therefore, there is an urgent need for a disc spring that is easy to install and fix, improves the convenience of installation and the accuracy of the installation position, and makes the disc spring have higher elastic efficiency and prevents failure. Summary of the invention

[0003] The utility model provides a furniture elastic connection claw type disc spring to overcome the deficiencies of the prior art.

[0004] To achieve the above purpose, a clamp elastically connected claw-type disc spring is designed, including a disc spring body with a conical ring structure, one side of the disc spring body is a small-mouth end, and the other side is a large-mouth end, and at least one end of the small-mouth end and the large-mouth end is provided with a radial clamping structure.

[0005] The radial clamping structure comprises a plurality of uniformly distributed clamping claws fixed on the outer side of the small-mouth end or the large-mouth end.

[0006] The number of the claws is 3.

[0007] Compared with the prior art, the utility model provides a radial clamping structure so that one end of the disc spring can clamp the shaft or other fixed components when the disc spring is extended and retracted, thereby keeping the position and direction of the disc spring from being eccentric, maintaining the elastic efficiency and preventing the disc spring from failing.

[0016] See also Figure 1-Figure 8 , wherein 1 is the disc spring body, 1-1 is the small end, 1-2 is the large end, 2 is the claw, 3 is the mounting plate, 4 is the mounting shaft, and 5 is the mounting slider. DETAILED DESCRIPTION

[0017] The utility model is further described below with reference to the accompanying drawings and embodiments. Example 1

[0018] like Figure 1-Figure 2 As shown, the radial clamping structure is arranged on the outside of the small-mouth end 1 - 1 of the disc spring body 1 of the conical ring structure, and the radial clamping structure is three evenly distributed claws 2.

[0019] When this embodiment is used, Figure 4-Figure 5 As shown, elastic support is required between the two mounting plates 3. A mounting slider 5 can be mounted on one side of the mounting shaft 4, and then a disc spring is arranged between the mounting slider 5 and the mounting plate 3. The large end 1-2 of the disc spring body 1 presses against the mounting plate 3, and the small end 1-1 of the disc spring body 1 presses against the mounting slider. The claw 2 holds the mounting shaft 4 from the radial outside, and the lower end can be kept fixed when the disc spring body 1 is extended and retracted up and down, thereby keeping the position and direction of the disc spring from being eccentric, maintaining the efficiency of the disc spring and preventing the disc spring from failing. Example 2

[0020] like Figure 4-Figure 5 As shown, the difference from Embodiment 1 is that the claw 2 is arranged on the outside of the large-mouth end 1 - 1 of the disc spring body 1 .

[0021] When this embodiment is used, Figure 7-Figure 8 As shown, the disc spring body 1 can be clamped on one side of the mounting slider 5 by the claw 2 outside the large end 1-2, so that the position and direction of the disc spring body 1 are fixed, and the small end 1-1 supports the mounting plate 3 to provide elastic force.
