Problems solved by technology

[0004] The hinge between the first plate 4' and the backrest 1' is usually connected by bolts. The bolt 3' passes through the first plate 4' and is connected to the backrest 1'. The first plate 4' can be wound around the bolt 3. 'Swing, in this way, the bolt 3' is used as the hinge shaft, and when the first plate 4' swings, a cir

Example Embodiment

[0034] Example 1

[0035] This embodiment provides a rotating assembly, such as Figure 2-Figure 5 As shown, the rotating assembly includes a rotating member 1, a blocking cover 2 and a locking member 3. The rotating member 1 includes a first cylindrical section 11 and a second cylindrical section 12 arranged in the axial direction. The shaft diameter of the first cylindrical section 11 is larger than that of the first cylindrical section 11. The diameter of the two cylindrical sections 12 is larger than that of the second cylindrical section 12 , and the blocking cover 2 is detachably connected to the outer end surface of the second cylindrical section 12 through the locking member 3 .

[0036] The rotating assembly can be applied to occasions where articulation is required. For example, if the first part and the second part need to be hinged, first connect the first cylindrical segment 11 to the first part, and after the second cylindrical segment 12 passes through the seco...

Example Embodiment

[0049] Embodiment 2

[0050] This embodiment provides a connecting assembly, an armrest and a seat. The difference between this embodiment and the first embodiment is that in this embodiment, the connecting hole 13 is provided with an embedded nut 14 , the locking member 3 is a screw, and the screw passes through the blocking cover 2 and is connected with the embedded nut 14 . By arranging the embedded nut 14, the processing requirements of the rotating member 1 are reduced, the processing of the rotating member 1 is more convenient, and the degree of cooperation with the screw is higher.

Example Embodiment

[0051] Embodiment 3

[0052] This embodiment provides a connecting assembly, an armrest and a seat. The difference between this embodiment and Embodiment 1 and Embodiment 2 is that: Figure 10 and Figure 11 As shown, in this embodiment, the end surface of the second cylindrical section 12 is provided with a groove 16 , and the end surface of the blocking cover 2 is provided with a convex strip 22 matched with the groove 16 . Since the second part (ie, the first plate 4 or the second plate 5 ) generates a circumferential frictional force on the blocking cover 2 when it rotates relative to the second cylindrical section 12 , the grooves 16 and the protruding strips 22 are arranged to cooperate with each other. , which can better limit the circumferential rotation of the blocking cover 2 , avoid screw loosening, and ensure a firm connection between the blocking cover 2 and the second cylindrical section 12 .

Abstract

The invention belongs to the technical field of home furnishing. The invention discloses a rotating assembly. The rotating assembly comprises a rotating piece, a blocking cover and a locking piece, the rotating piece comprises a first cylindrical section and a second cylindrical section which are arranged in the axial direction, the shaft diameter of the first cylindrical section is larger than that of the second cylindrical section, the diameter of the blocking cover is larger than that of the second cylindrical section, and the blocking cover is detachably connected to the end face of the second cylindrical section through the locking piece. The stability of a hinge structure can be improved through the rotating assembly, and loosening is not likely to happen.

Description

technical field [0001] The invention relates to the field of household technology, in particular to a rotating assembly, an armrest and a seat. Background technique [0002] A traditional seat includes a seat board, a backrest and a driving mechanism. The backrest is rotatably connected to the seat board and can swing relative to the seat board under the action of the driving mechanism to adjust the angle of the backrest to meet the needs of the human body. [0003] Such as figure 1 As shown, the seat with adjustable backrest angle is usually provided with an armrest on the left and right sides of the backrest 1', and the armrest includes a first plate 4' and a second plate 5', and the first plate 4' One end is hinged with one end of the second plate 5', the other end of the first plate 4' is hinged with the backrest 1' of the seat, and the other end of the second plate 5' is hinged with the seat plate 2' of the seat, thus , when the angle of the backrest 1' is adjusted, a...
