Description

一种转动组件、扶手及座椅Rotating component, armrest and seat 技术领域Technical field

The backrest is rotatably connected to the seat plate and can swing relative to the seat plate under the action of the driving mechanism, thereby adjusting the angle of the backrest to meet the needs of the human body.
如图1所示，通常这种可调节靠背角度的座椅在靠背1’的左右两侧各设置有一个扶手，扶手包括第一板件4’和第二板件5’，第一板件4’的一端与第二板件5’的一端铰接，第一板件4’另一端与座椅的靠背1’铰接，第二板件5’的另一端与座椅的座板2’铰接，由此，在调节靠背1’角度时，随着靠背1’的转动，第一板件4’和第二板件5’能够适应性地摆动。As shown in Figure 1, usually this kind of seat with adjustable backrest angle is provided with an armrest on the left and right sides of the backrest 1'. The armrest includes a first plate 4'and a second plate 5'. The first plate One end of 4'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 Therefore, when the angle of the backrest 1'is adjusted, the first plate 4'and the second plate 5'can swing adaptively as the backrest 1'rotates.
第一板件4’和靠背1’之间的铰接通常采用螺栓连接的方式，螺栓3’穿过第一板件4’后与靠背1’连接，第一板件4’能够绕着螺栓3’摆动，这种方式以螺栓3’作为铰接轴，在第一板件4’摆动时对螺栓3’产生周向的摩擦力，经过多次使用后容易造成螺栓3’松动，进而导致第一板件4’晃动。同样地，第二板件5’和座椅2’之间的螺栓3’也容易发生松动的情况，导致第二板件5’晃动。因此，采用螺栓连接的方式在多次调节靠背角度后会造成扶手晃动设置脱落的情况。The hinge connection between the first plate 4'and the backrest 1'is usually bolted. The bolt 3'passes through the first plate 4'and then connects to the backrest 1'. The first plate 4'can surround the bolt 3. 'Swing, in this way, the bolt 3'is used as the hinge axis. When the first plate 4'swings, it produces circumferential friction on the bolt 3'. After multiple uses, it is easy to cause the bolt 3'to loosen. The plate 4'shakes. Similarly, the bolts 3'between the second plate 5'and the seat 2'are also prone to looseness, causing the second plate 5'to shake. Therefore, the use of bolt connection will cause the armrest to shake and fall off after adjusting the angle of the backrest several times.

实施例一Example one
本实施例提供了一种转动组件，如图2-图5所示，转动组件包括转动件1、挡盖2及锁紧件3，转动件1包括沿轴向设置的第一圆柱段11和第二圆柱段12，第一圆柱段11的轴径大于第二圆柱段12的轴径，挡盖2的直径大于第二圆柱段12的轴径，挡盖2通过锁紧件3可拆卸地连接于第二圆柱段12的外端面。This embodiment provides a rotating assembly. As shown in Figures 2 to 5, 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 The second cylindrical section 12, the shaft diameter of the first cylindrical section 11 is greater than the shaft diameter of the second cylindrical section 12, the diameter of the blocking cover 2 is greater than the shaft diameter of the second cylindrical section 12, the blocking cover 2 is detachably through the locking member 3 Connected to the outer end surface of the second cylindrical section 12.
该转动组件可以应用于需要实现铰接的场合。例如需要将第一零件（背板或座板）和第二零件（对应地，第一板件或第二板件）铰接，则先将第一圆柱段11连接于第一零件上，第二圆柱段12穿过第二零件后，将挡盖2与第二零件连接。通过该转动组件能够提高铰接结构的稳定性，不易松动。由此，转动件1相对于第一零件固定，第二圆柱段12穿过第二零件，并将挡盖2连接于第二圆柱段12的端面，在第二零件相对第一零件转动时，实质上是第二零件在第二圆柱段12上转动，转动过程中第二零件被限制于第一圆柱段11和挡盖2之间，不易脱落。The rotating assembly can be applied to occasions that need to realize articulation. For example, if the first part (back plate or seat plate) and the second part (correspondingly, the first plate or the second plate) need to be hinged, first connect the first cylindrical section 11 to the first part After the second cylindrical section 12 passes through the second part, the blocking cover 2 is connected with the second part. Through the rotating assembly, the stability of the hinge structure can be improved, and it is not easy to loosen. Thus, the rotating part 1 is fixed relative to the first part, the second cylindrical section 12 passes through the second part, and the blocking cover 2 is connected to the end surface of the second cylindrical section 12, and the second part is opposite to the first zero. When the part rotates, the second part essentially rotates on the second cylindrical section 12. During the rotation, the second part is restricted between the first cylindrical section 11 and the blocking cover 2 and is not easy to fall off.
转动件1沿轴向开设有至少两个贯穿转动件1的连接孔13，连接孔13可以为螺纹孔，锁紧件3为螺钉，挡盖2上开设有安装孔21，螺钉穿过挡盖2上的安装孔21后与螺纹孔配合连接。通过螺钉连接的方式将挡盖2连接于转动件1的第二圆柱段12的端面，安装和拆卸均较方便；此外，由于第二零件相对第二圆柱段12转动时可能会对挡盖2产生的周向的摩擦力，通过设置两个连接孔13，能够从两个位置进行连接，从而限制挡盖2的周向转动。The rotating part 1 is provided with at least two connecting holes 13 passing through the rotating part 1 along the axial direction. The connecting holes 13 can be threaded holes, the locking part 3 is a screw, and the blocking cover 2 is provided with a mounting hole 21, and the screw passes through the blocking cover. The mounting hole 21 on 2 is then matched with the threaded hole. The blocking cover 2 is connected to the end surface of the second cylindrical section 12 of the rotating part 1 by screw connection, which is convenient to install and disassemble; in addition, because the second part rotates relative to the second cylindrical section 12, the blocking cover may be affected. 2. The circumferential friction force generated by the two connecting holes 13 can be connected from two positions, thereby restricting the circumferential rotation of the blocking cover 2.
第一圆柱段11与第一零件之间的连接也可以采用螺钉连接的方式，由于转动件1沿轴向开设有贯穿转动件1的连接孔13，该连接孔13也可用于第一圆柱段11与第一零件之间的连接。由于第二零件相对转动件1转动时对转动件1造成的周向上的摩擦力，为了避免转动件1相对第一零件的转动，用于第一圆柱段11与第一零件之间的连接的螺钉也可以设置有至少两个。由于设置有至少两个螺钉，一方面可以避免转动件1相对第一零件的转动，进而避免螺钉松动；另一方面，相对于设置一个螺钉，至少两个螺钉能够更好地支撑转动件1及第二零件，每个螺钉受到的压力更小，不易变形。The connection between the first cylindrical section 11 and the first part can also be a screw connection. Since the rotating part 1 is provided with a connecting hole 13 passing through the rotating part 1 in the axial direction, the connecting hole 13 can also be used for the first cylinder. The connection between the section 11 and the first part. Due to the circumferential friction caused by the second part on the rotating part 1 when the second part rotates relative to the rotating part 1, in order to avoid the rotation of the rotating part 1 relative to the first part, it is used between the first cylindrical section 11 and the first part The connecting screws can also be provided with at least two. Since at least two screws are provided, on the one hand, the rotation of the rotating part 1 relative to the first part can be avoided, thereby avoiding the loosening of the screws; on the other hand, compared with one screw, the at least two screws can better support the rotating part 1 And the second part, the pressure on each screw is smaller and it is not easy to deform.
进一步地，为了避免转动件1相对第一零件的转动，如图3所示，第一圆柱段11的端面可以开设有凹坑15，第一零件上可以设置有与凹坑15配合的凸块，在将第一圆柱段11与第一零件连接前，先通过凹坑15与凸块的配合将第一圆柱段11与第一零件插接，再通过螺钉进行连接。由此，既方便了两者的连接时的定位过程，也能够避免转动件1相对第一零件的转动。优选的，凹坑15可以设置有两个。凹坑15的形状可以为扇形、矩形、圆形、椭圆形、多边形等。Further, in order to avoid the rotation of the rotating member 1 relative to the first part, as shown in FIG. 3, the end surface of the first cylindrical section 11 may be provided with a pit 15 and the first part may be provided with a matching hole 15 For the convex block, before connecting the first cylindrical section 11 with the first part, the first cylindrical section 11 is inserted into the first part through the cooperation of the recess 15 and the convex block, and then the first cylindrical section 11 is connected with the first part by screws. Therefore, the positioning process during the connection of the two is facilitated, and the rotation of the rotating part 1 relative to the first part can also be avoided. Preferably, two pits 15 may be provided. The shape of the pit 15 may be a fan shape, a rectangle, a circle, an ellipse, a polygon, and the like.
转动件1和/或挡盖2由尼龙棒制成。尼龙棒具有韧性好、耐磨力强、耐油、抗震、拉伸、弯曲强度好，并具有吸水性小、尺寸稳定性好等特点，尼龙棒是以塑代钢、铁、铜等金属的好材料，是重要的工程塑料。转动件1采用尼龙棒制成，使得转动件1的耐磨性能好，在长期使用后磨损仍较少，非常适用于转动件1的滚动状态。The rotating part 1 and/or the blocking cover 2 are made of nylon rods. Nylon rods have good toughness, strong abrasion resistance, oil resistance, shock resistance, tensile, bending strength, and have the characteristics of low water absorption and good dimensional stability. Nylon rods are made of plastic instead of steel, iron, copper and other metals. Materials are important engineering plastics. The rotating part 1 is made of nylon rod, so that the rotating part 1 has good abrasion resistance and is still less worn after long-term use, which is very suitable for the rolling state of the rotating part 1.
