Abstract
A joint mechanism comprises a lower arm and an upper arm. The lower arm and the upper arm are connected through a rotary shaft and shaft holes. The lower arm is provided with a left pivot-joint base and a right pivot-joint base. A connecting space is formed between the left pivot-joint base and the right pivot-joint base. The left pivot-joint base and the right pivot-joint base are each provided with one of the shaft holes and a plurality of fixing holes which are evenly distributed around the shaft hole. The upper arm is provided with elastic clamping parts, limiting plates, a connecting base and bearings. The elastic clamping parts are evenly distributed relative to the bearings. When the upper arm and the lower arm are connected, the bearings are mounted in the shaft holes so that the upper arm can rotate relative to the lower arm. The invention provides a novel table lamp and the joint mechanism of the novel table lamp with the advantages that positioning and fixation are reliable, and the antigravity effect is good.

Property clamping piece hole again from connecting seat in stretch out, and put in fixing hole, left pin joint seat or Thuban joint chair are blocked again, make a left side
Pin joint seat or Thuban joint chair and connecting seat be not relative to moving.
Elastic clamping piece can arrange multiple, and the quantity for arranging is more, and upper arm is more stable with underarm, and certain user adjusts
Section upper arm relative to underarm position when the power that needs will be bigger.
The desk lamp also includes the first arm, the second arm, the 3rd arm, the 4th arm, the first connector, the second connector and the 3rd
Connector；, being connected by the first connector between the first arm and the second arm, the second arm and the 3rd arm are connected by the second connector
Connect, the 3rd arm is connected with the 4th arm by the 3rd connector, the 4th arm is connected with lamp；The upper arm, underarm can be the first arm,
Any pair or multipair in second arm, the 3rd arm, the 4th arm, the rotary shaft and axis hole can be the first connector, second
It is any one or more in connector and the 3rd connector.
Beneficial effect：
The invention provides a kind of reliable location fix, antigravity effect preferably novel reading lamp and its articulation mechanism.
Description of the drawings
With reference to the accompanying drawings and detailed description the present invention is further detailed explanation.
Fig. 1 is the schematic diagram of desk lamp in the present invention；
Fig. 2 is underarm and upper arm schematic diagram after mounting；
Fig. 3 is the exploded perspective view of underarm and upper arm；
Fig. 4 is the close-up schematic view that elastic clamping piece is snapped fit onto on fixing hole.
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 connects, 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 are by 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 be provided with it is 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
The relative bearing 31 of clamping piece 15 is uniformly arranged；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 installing 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 provides bullet for elastic clamping piece 15
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

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
When clamping piece 15 is extend in fixing hole 14, 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 in the hole that is retracted on connecting seat 21；When with
When family is adjusted 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, left pin joint seat 11 or Thuban joint chair 12 and connecting seat 21 is made relative to not moving.
Those of ordinary skill in the art be easy for it is contemplated that, elastic clamping piece 15 can arrange multiple, and arrange number
Amount is more, and upper arm 2 is more stable with underarm 1, certain user regulation upper arm 2 relative to underarm 1 position when the power that needs will
It is bigger.
In the present invention, the upper arm, underarm can be in the first arm 101, the second arm 102, the 3rd arm 201, the 4th arm 202
Any pair or multipair, the rotary shaft 3 and axis hole 13 can be the first connector 103, the second connector 203 and the 3rd company
It is any one or more in fitting 303.
Above-described embodiment is intended merely to the purposes of the interpretation present invention, and is not limitation of the present invention, this technology
The those of ordinary skill in field, in the essential scope of the present invention, makes a variety of changes or substitutes, and should also belong to the guarantor of the present invention
Shield category.
