In the scheme of this application, can directly utilize the connector 31 with lamp holder casing 32's structure cooperation is realized the connector 31 with lamp holder casing 32 axial between them is spacing, and overall structure is simple, and it is convenient to make, and the installation is firm.

Referring to fig. 6, 7 and 9, the anti-slip structure 34 includes an anti-slip member 341 and an anti-slip groove 342.

Referring to fig. 6 and 7, wherein the escape prevention groove 342 is formed on the outer circumferential surface of the shaft 310,

referring to fig. 6, the anti-slip member 341 is disposed in the axial hole 320, and the anti-slip member 341 is inserted into the anti-slip groove 342. In this manner, the disengagement preventing member 341 can rotate circumferentially in the disengagement preventing groove 342, and can be axially restrained by the disengagement preventing groove 342.

With continued reference to fig. 9, in the present embodiment, the anti-releasing member 341 is formed on a side of the pressing ring 322 facing the main housing 321.

In practical implementation, the anti-slip member 341 can be adapted according to the configuration of the axial hole 320. For example, when the shaft hole 320 is formed by circumferentially splicing the main housing 321 and the pressing ring 322, the anti-slip member 341 may be integrally formed on the other of the main housing 321 and the pressing ring 322. And when the shaft hole 320 is formed by the main housing 321, the escape preventing member 341 is disposed on the pressing ring 322.

Referring to fig. 6, 7 and 8, a rotation angle limiting structure 35 is formed between the shaft 310 and the shaft hole 320 to limit the range of the rotation angle of the lamp head housing 32 relative to the connection head 31. In the solution of the present application, the limitation of the rotation angle of the connection head 31 and the lamp head housing 32 is realized by directly utilizing the structural cooperation of the shaft 310 and the shaft hole 320, that is, utilizing the structural cooperation of the connection head 31 and the lamp head housing 32. So set up, simple structure, it is convenient to make, and the installation is firm.

With continued reference to fig. 6, 7 and 8, the limiting structure 35 includes a limiting protrusion 351 and a limiting groove 352.

Referring to fig. 7, the limiting protrusion 351 is an arc-shaped protrusion extending along the outer circumferential surface of the shaft 310, and the limiting protrusion 351 extends from the shaft shoulder 311 in the axial direction. And the restriction groove 352 is an arc-shaped notch formed at the open end of the shaft hole 320. With this design, the rotation angle limiting structure 35 is not disposed to interfere with the assembly of the shaft 310 and the shaft hole 320.

In other embodiments, for example, when the axial hole 320 is formed by circumferentially splicing the main housing 321 and the pressing ring 322, the axial position of the limiting structure 35 is limited. In this case, the restricting protrusion 351 may be provided on the inner surface of the shaft hole 320, and the restricting groove 352 may be opened on the outer circumferential surface of the shaft.

In this application in lamps and lanterns 100, with lamp holder pole 24 the dead lever 21 telescopic link 22 with connecting rod 23 sets up to the link mechanism of crank loose piece to utilize elastic element 25 to balance fall lamp holder pole 24 and by the lamp holder that lamp holder pole 24 bore or the gravity of casing subassembly 30 can balance the gravity of falling lamp holder or casing subassembly 30 in the lift adjustment in-process, can realize the effect of arbitrary position fixing in the lift simultaneously. In addition, the elastic element 25 is accommodated in the fixing rod 21, and the whole structure is neat and simple.

Furthermore, the lamps and lanterns of this application, directly utilize structure formation matched with axle 310 and shaft hole 320 between connector 31 and lamp holder casing 32, and arrange elasticity circle 33 between axle 310 and shaft hole 320, can provide the rotation that can fix at will for lamp holder casing 32 and connector 31 and connect, need not additionally to set up pivot part, it is complicated to solve current lamps and lanterns structure, high in production cost, be not convenient for use, and the relatively poor scheduling problem of practicality, furthermore, in the scheme of this application, the structure cooperation that utilizes connector 31 and lamp holder casing 32 forms anti-disengaging structure 34 and restriction angle 35 in axle 310 and shaft hole 320, make connector 31 and lamp holder casing 32 fixed not drop.
