Specific embodiment
As shown in figure 1, desk lamp includes the first arm 101, the second arm 102, the 3rd arm 201, the 4th arm 202, the first connector
103rd, the second connector 203 and the 3rd connector 303；As illustrated, connecting by first between the first arm 102 and the second arm 102
Fitting 103 is connected, and the second arm 102 is connected with the 3rd arm 201 by the second connector 203, and the 3rd arm 201 and the 4th arm 202 lead to
Cross the 3rd connector 303 to connect, the 4th arm 202 is connected with lamp.
As in Figure 2-4, articulation mechanism is made up of underarm 1, upper arm 2, and underarm 1, upper arm 2 pass through rotary shaft 3 and axis hole 13
Connection, is provided with left pin joint seat 11 and Thuban joint chair 12 on underarm 1, connection is provided between left pin joint seat 11 and Thuban joint chair 12
Space 16；Axis hole 13 and fixing hole 14 are provided with left pin joint seat 11, Thuban joint chair 12；Fixing hole 14 is provided with multiple, and around
The even circumferential arrangement of axis hole 13.Elastic clamping piece 15, limiting plate 17, connecting seat 21 and bearing 31 are provided with upper arm 2；Elasticity
Clamping piece 15 is uniformly arranged with respect to bearing 31；When upper arm 2 is connected with underarm 1, bearing 31 is installed in axis hole 13, so as to upper arm
2 can rotate relative to underarm 1.
As shown in figure 4, connecting seat 21 is internally provided with mounting hole, elastic clamping piece 15 is arranged in the hole, and can
Relatively described hole moves up and down；The lower section of elastic clamping piece 15 is additionally provided with spring 18, and spring is that elastic clamping piece 15 provides bullet
Property power, makes elastic clamping piece 15 remain protruding；Limiting plate 17 is placed on outside connecting seat 21, is equally set on limiting plate 17
Hole is equipped with, the diameter of the boring ratio elasticity correspondence position of clamping piece 15 on limiting plate 17 is small, therefore limiting plate 17 can limit elasticity
The movement of clamping piece 15, makes elastic clamping piece 15 not depart from completely from connecting seat 21.
In the course of the work, outwardly directed part is circular shape on elastic clamping piece 15, and the circular arc portion extend into
In the fixing hole 14 of left pin joint seat 11 or Thuban joint chair 12, to give left pin joint seat 11 or Thuban joint chair 12 1 power, work as elasticity
Clamping piece 15 is extend into when in fixing hole 14, and left pin joint seat 11 or Thuban joint chair 12 are not moved relative to connecting seat 21；So that on
Arm 2 and underarm 1 be not relative to moving.
When user need to adjust upper arm 2 relative to underarm 1 position when, apply an external force to upper arm 2 or underarm 1,
Left pin joint seat 11 or Thuban joint chair 12 will be moved relative to connecting seat 21, and left pin joint seat 11 or Thuban joint chair 12 will be to elasticity
15 1 power of clamping piece, make elastic clamping piece 15 overcome the elastic force of spring 18 and be retracted into the hole on connecting seat 21；When with
When family regulation is to relevant position, elastic clamping piece 15 stretches out in hole again from connecting seat 21, and puts in fixing hole 14, again
Left pin joint seat 11 or Thuban joint chair 12 are blocked, makes left pin joint seat 11 or Thuban joint chair 12 and connecting seat 21 relative to not moving.
Those of ordinary skill in the art be easy for it is contemplated that, elastic clamping piece 15 can set multiple, and the number for setting
Amount is more, and upper arm 2 is more stable with underarm 1, certain user adjust upper arm 2 relative to underarm 1 position when the power that needs will
It is bigger.
In the utility model, the upper arm, underarm can be the first arm 101, the second arm 102, the 3rd arm 201, the 4th arm
Any pair or multipair in 202, the rotary shaft 3 and axis hole 13 can be the first connector 103, the and of the second connector 203
It is any one or more in 3rd connector 303.
Above-described embodiment is intended merely to interpretation purposes of the present utility model, and is not to limit of the present utility model
System, those skilled in the art in essential scope of the present utility model, make a variety of changes or substitute, and also should
Belong to protection category of the present utility model.
