Thus, the elastic structure 333 is formed on the braking member 33 formed integrally, so that the second abutting end 332 on the braking member 33 can be matched with the slot 3111 on the first rotating body 31 to lock the first rotating body 31 and the second rotating body 32, and thus, when the lamp body 20 of the lamp 100 is arranged on the first rotating body 31 or the second rotating body 32, the braking member 33 can lock the lamp body 20 to fix the lighting angle of the lamp 100, which not only can meet the requirement of a user on the lighting angle, but also can prevent the lamp body 20 from rotating freely to influence the lighting effect in the using process of the lamp 100. Meanwhile, the elastic structure 333 is formed on the integrally formed stopper 33 to elastically abut the second abutting end 332 against the slot 3111, so that the stepped rotation and locking between the first rotating body 31 and the second rotating body 32 are realized, and the abutting and locking are realized without a spring and a pin.

Specifically, in the embodiment of the present invention, the braking member 33 may be made of a plastic material, for example, the braking member 33 may be integrally injection molded, that is, the braking member 33 may be a plastic member.

After the whole lamp 100 is assembled, when the rotation angle between the first rotator 31 and the second rotator 32 needs to be changed, a user can apply a rotational force to either one of the first rotator 31 and the second rotator 32, and when the first rotator 31 or the second rotator 32 rotates relatively under the action of an external force, the second abutting end 332 can overcome the elastic force of the elastic structure 333 and move towards the direction of the elastic structure 333 to further compress the elastic structure 333, and the second abutting end 332 is separated from the original slot 3111, so that the locking between the first rotator 31 and the second rotator 32 is released. After the first rotating body 31 and the second rotating body 32 rotate to a desired position, the second abutting end 332 is clamped into the corresponding clamping groove 3111 again under the elastic force of the elastic structure 333 to realize angle adjustment, that is, to realize step rotation and hovering of the lamp body 20.

Example two

Referring to fig. 4 and 6, in some embodiments, the elastic structure 333 may include a plurality of curved connecting ribs 3331 connected between the first abutting end 331 and the second abutting end 332 and disposed at intervals.

Thus, the connection rib 3331 is curved to enable the connection rib 3331 to have a certain elastic deformation capability, so that the elastic structure 333 has a certain deformation capability to apply an elastic force to the second abutting end 332, thereby ensuring the stability of locking.

Specifically, in such an embodiment, when the braking member 33 is manufactured, it is only necessary to design the braking member 33 correspondingly to the mold so that the intermediate position of the braking member 33 can be formed with the spaced connection ribs 3331.

Further, as shown in fig. 4, in some embodiments, the connecting rib 3331 may be waved. So, set up splice bar 3331 into the wavy deformation that can make splice bar 3331 take place under the exogenic action in order to produce elastic force, simultaneously, the toughness of wavy splice bar 3331 is better, can avoid splice bar 3331 to be compressed repeatedly under the exogenic action and lead to the splice bar 3331 fracture, improves life.

Further, in some embodiments, the number of the connecting ribs 3331 is at least 3.

Thus, the number of the connecting ribs 3331 is set to be at least 3, so that the number of the connecting points between the elastic structure 333 and the second abutting end 332 is at least 3, and it is avoided that the second abutting end 332 is subjected to two-side deviation when the force is applied due to too few connecting points of the second abutting end 332, for example, when the number of the connecting ribs 3331 is one or two, the elastic force only acts on one point position or two point positions, and the force applied to the second abutting end 332 is uneven and unstable, which is prone to one-side deflection.

Simultaneously, the quantity of splice bar 3331 sets up to 3 at least sizes that also can guarantee the elastic force, and it is less to avoid the quantity of splice bar 3331 less and lead to the elastic force less, and then leads to first turning and the second to turn and only need can take place relative rotation under tiny effort, stability when improving the locking.

Specifically, as shown in fig. 4, in the embodiment shown in fig. 4, the number of the connecting ribs 3331 is 4, two of the connecting ribs are located in the middle of the second abutting end 332, the other two connecting ribs are located at two sides of the second abutting end 332, and the four connecting ribs 3331 jointly apply an elastic force to the second abutting end 332 to ensure that the elastic force is sufficient, so as to ensure the stability of the locking.

Further, in some embodiments, the spacing distance between two adjacent connecting ribs 3331 is the same.

Therefore, the connection ribs 3331 are uniformly spaced to ensure the uniformity of the force application, so as to improve the stability of the second abutting end 332 in cooperation with the slot 3111.

EXAMPLE III

Referring to fig. 3 and 5, in some embodiments, the second rotator 32 may have a mounting groove 322 formed thereon, an opening of the mounting groove 322 faces the rotation connection portion 311, the braking member 33 is mounted in the mounting groove 322, and the second abutting end 332 extends out of the mounting groove 322 and is clamped into the slot 3111.

In this manner, the installation groove 322 is provided to stably install the braking member 33 to prevent the braking member 33 from being displaced during the rotation of the first and second rotors 31 and 31.

Specifically, in such an embodiment, the shape of the mounting groove 322 may match the shape of the braking element 33, the braking element 33 may be preferably mounted in the mounting groove 322 in a clearance fit manner so that the second abutting end 332 can move, the second abutting end 332 of the braking element 33 may slightly extend out of the mounting groove 322 to be clamped into the clamping groove 3111 on the first rotating shaft portion 311 and abut against the inner wall of the clamping groove 3111, and the mounting groove 322 may limit the braking element 33 so that the second abutting end 332 does not shift greatly when being pressed, thereby ensuring the stability of locking and unlocking.

Example four

In some embodiments, the length of the second abutting end 332 along the axial direction of the first rotating shaft portion 311 is at least half of the length of the first rotating shaft portion 311.

Thus, setting the length of the second abutting end 332 to be at least half of the length of the first rotating shaft 311 can make the engaging area between the second abutting end 332 and the slot 3111 on the first rotating shaft 311 larger, and avoid that the contact range between the second abutting end 332 and the slot 3111 is too small, which causes the second abutting end 332 to easily disengage from the slot 3111 under a small acting force, thereby causing unstable locking.

Specifically, it should be noted that the length of the second abutting end 332 refers to the length in the axial direction of the first rotating shaft portion 311, and correspondingly, the length of the slot 3111 may be substantially the same as the length of the second abutting end 332 or the length of the slot 3111 is slightly greater than the length of the second abutting end 332, which is not limited herein.

In the embodiment shown in fig. 3, the length of the second abutting end 332 may be substantially the same as the length of the first rotation shaft 311, however, in other embodiments, the length of the braking member 33 may also be smaller than the length of the first rotation shaft 311, and it is only necessary to ensure that the ratio between the length of the second abutting end 332 and the length of the first rotation shaft 311 is greater than one half, for example, the ratio may be two thirds, three quarters, and the like, and the specific description is not limited herein.

EXAMPLE five

Therefore, the arrangement of the first and second shaft mounting portions 3211 and 3212 can ensure the stability of the rotation of the first shaft portion 311, and the brake member 33 is disposed between the first and second shaft mounting portions 3211 and 3212 to hide the brake member 33, so that the brake member 33 is not exposed, thereby improving the aesthetic appearance.

Specifically, as shown in fig. 3, in such an embodiment, the spacing distance between the first and second spindle mounting portions 3211 and 3212 may be the same as the length of the first spindle portion 311 or slightly greater than the length of the first spindle portion 311 to ensure compactness of assembly. The mounting groove 322 may be formed between the first shaft mounting portion 3211 and the second shaft mounting portion 3212.

More specifically, in the embodiment shown in fig. 3-6, the first rotating shaft portion 311 and the first rotating body 31 can be rotatably connected by the rotating shaft 34 passing through the first rotating shaft mounting portion 3211, the first rotating shaft portion 311 and the second rotating shaft mounting portion 3212.

Of course, it is understood that in other embodiments, rotation shaft holes may be formed in the first rotation shaft mounting portion 3211 and the second rotation shaft mounting portion 3212, and rotation shaft protrusions may be formed at both ends of the first rotation shaft portion 311, and during assembly, the rotation shaft protrusions may be snapped into the rotation shaft holes in the first rotation shaft mounting portion 3211 and the second rotation shaft mounting portion 3212 by applying an assembly force to the first rotation shaft portion 311, so as to implement rotation connection, which is not limited herein.

Example six

In this way, the second rotating shaft part 312 and the third rotating shaft part 313 are arranged so that a space is formed between the first rotating shaft part 311 and each of the second rotating shaft part 312 and the third rotating shaft part 313, and when assembling, the first rotating shaft mounting part 3211 and the second rotating shaft mounting part 3212 can be inserted into the two spaces respectively to position the first rotating body 31 and the second rotating body 32, thereby facilitating subsequent assembling.
