Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0032] Please also read Figures 1 to 5 , the hinge provided by the embodiment of the present application is now described. The hinge comprises: a first leaf 10, a second leaf 20, a deformable sleeve 50 and a shaft body 60, wherein the first leaf 10 is provided with a first sleeve 11; the second leaf 20 is provided with a second sleeve 21; the deformable sleeve 50 is provided along the central axis Z through the first sleeve 11 and the second sleeve 21, the two ends of the deformable sleeve 50 along the central axis Z are respectively a first end 51 and a second end 52, the deformable sleeve 50 is provided with an inner cavity 53, and the cross section of the inner cavity 53 gradually decreases from the first end 51 to the second end 52; the shaft body 60 comprises an adjusting section 61, the adjusting section 61 is provided through the inner cavity 53, and presses the deformable sleeve 50 to abut against the first sleeve 11 and the second sleeve 21, and the cross section of the adjusting section 61 gradually decreases from the first end 51 to the second end 52.

[0033] Among them, one of the first leaf 10 and the second leaf 20 is connected to the lamp, and the other is connected to the bracket, for example, the first leaf 10 is connected to the lamp, and the second leaf 20 is connected to the bracket, or the first leaf 10 is connected to the bracket, and the second leaf 20 is connected to the lamp. It should be noted that in other embodiments, the hinge can also be used to connect other two parts that need to be relatively rotatable, such as a box cover and a box body.

[0034] Optionally, see Figure 1 and Figure 2 The first leaf 10 and the first sleeve 11 are made of metal, and the first sleeve 11 and the first leaf 10 can be integrally formed or welded. The second leaf 20 and the second sleeve 21 are also made of metal, and the second sleeve 21 and the second leaf 20 can be integrally formed or welded.

[0035] The first sleeve 11 and the second sleeve 21 are arranged along the central axis Z and are coaxial with the central axis Z.

[0036] See also Figure 3 and Figure 4 , the deformable sleeve 50 is coaxial with the central axis Z, and the deformable sleeve 50 is a structure capable of generating axial deformation, so that the deformable sleeve 50 can abut against the first sleeve 11 and the second sleeve 21 under the pressure of the shaft body 60, and the deformable sleeve 50 can rotate around the central axis Z relative to the first sleeve 11 and / or the second sleeve 21, so that the first leaf 10 can rotate around the central axis Z relative to the second leaf 20. Specifically in this embodiment, the deformable sleeve 50 can rotate around the central axis Z relative to the second sleeve 21, but cannot rotate relative to the first sleeve 11. Of course, in other embodiments, the deformable sleeve 50 can also rotate around the central axis Z relative to the first sleeve 11, but cannot rotate relative to the second sleeve 21; or, the deformable sleeve 50 can rotate around the central axis Z relative to both the first sleeve 11 and the second sleeve 21.

[0037] The length of the inner cavity 53 extends along the central axis Z, and the cross-section of the inner cavity 53 refers to a plane of the inner cavity 53 perpendicular to the central axis Z.

[0038] The shaft body 60 is coaxial with the central axis Z, and the adjustment section 61 is adapted to the inner cavity 53. The adjustment section 61 squeezes the inner wall of the deformation sleeve 50, so that the deformation sleeve 50 has a tendency to deform axially outward, thereby making the outer wall of the deformation sleeve 50 abut against the inner wall of the first sleeve 11 and the inner wall of the second sleeve 21. The cross section of the adjustment section 61 refers to the plane of the adjustment section 61 perpendicular to the central axis Z.

[0039] Since the cross section of the inner cavity 53 gradually decreases along the center axis Z from the first end 51 to the second end 52, and the cross section of the adjustment section 61 also gradually decreases along the center axis Z from the first end 51 to the second end 52, when the adjustment section 61 moves along the center axis Z from the first end 51 to the second end 52, the extrusion force of the adjustment section 61 on the deformation sleeve 50 gradually increases, that is, the adjustment section 61 continues to squeeze the deformation sleeve 50 to have a tendency to deform outward axially, so that the friction between the deformation sleeve 50 and the first sleeve 11 and the second sleeve 21 increases, and further the damping between the first leaf 10 and the second leaf 20 also increases. Similarly, when the adjustment section 61 moves along the center axis Z from the second end 52 to the first end 51, the extrusion force of the adjustment section 61 on the deformation sleeve 50 gradually decreases, so that the friction between the deformation sleeve 50 and the first sleeve 11 and the second sleeve 21 decreases, and further the damping between the first leaf 10 and the second leaf 20 also decreases.

[0040] Compared with the prior art, the hinge provided by the present application has one of the first leaf piece 10 and the second leaf piece 20 connected to the lamp, and the other connected to the bracket, and the deformation sleeve 50 is passed through the first shaft sleeve 11 and the second shaft sleeve 21 along the central axis Z, and abuts against the first shaft sleeve 11 and the second shaft sleeve 21 under the pressure of the adjustment section 61, so that the first shaft sleeve 11 can rotate relative to the second shaft sleeve 21 around the central axis Z, and then the first leaf piece 10 can rotate relative to the second leaf piece 20, and the cross section of the inner cavity 53 is gradually reduced from the first end 51 to the second end 52, and the cross section of the adjustment section 61 is increased from the first end 51 to the second end 52. The direction of the end 52 gradually decreases, so that when the adjusting section 61 moves along the central axis Z, the squeezing force of the adjusting section 61 on the deformable sleeve 50 increases or decreases, and then the friction between the deformable sleeve 50 and the first shaft sleeve 11 and the first shaft sleeve 11 increases or decreases, thereby realizing the adjustment of the damping size between the first leaf 10 and the second leaf 20, which can meet the user's usage needs. For example, when a heavier lamp needs to be rotatably connected to the bracket through the hinge, the damping of the hinge can be increased. In this way, when no external force is applied to the lamp, the lamp can be stably maintained at the preset angle position, which is beneficial to improving the user's usage experience.

[0041] Specifically in this embodiment, the lamp is a strip lamp, the first leaf 10 is connected to the lamp, and the second leaf 20 is connected to the bracket.

[0042] In one embodiment of the present application, see Figure 1 and Figure 2 The first leaf 10 is provided with a first fixing hole 12 , and the length of the first fixing hole 12 extends along the central axis Z.

[0043] A fastener such as a screw is connected to the lamp by penetrating the first fixing hole 12, so that the first leaf 10 is connected to the lamp. Since the length of the first fixing hole 12 extends along the central axis Z, the first fixing hole 12 is roughly in a strip shape along the central axis Z, so that the fastener can adjust the connection between the first leaf 10 and the lamp by penetrating different positions of the first fixing hole 12, thereby achieving fine adjustment of the relative position between the lamp and the bracket along the central axis Z.

[0044] Optionally, there are two first fixing holes 12 , which are spaced apart along the central axis Z. The provision of two first fixing holes 12 is helpful to enhance the stability of the connection between the first leaf 10 and the lamp.

[0045] The first leaf 10 is further provided with a second fixing hole 13 , which extends in a direction perpendicular to the central axis Z.

[0046] Optionally, the second fixing hole 13 is located between the two first fixing holes 12 .

[0047] A fastener such as a screw is connected to the bracket by penetrating the second fixing hole 13, so that the first leaf 10 is connected to the bracket. Since the length of the second fixing hole 13 extends in a direction perpendicular to the central axis Z, the second fixing hole 13 is roughly in a strip shape in the direction perpendicular to the central axis Z, so that the fastener can adjust the connection between the first leaf 10 and the lamp by penetrating different positions of the second fixing hole 13, thereby realizing that the relative position between the lamp and the bracket in the direction perpendicular to the central axis Z can be finely adjusted.

[0048] The second leaf 20 is provided with a mounting hole 22 , and a fastener such as a screw is connected to the bracket through the mounting hole 22 , so that the second leaf 20 is connected to the bracket.

[0049] There are multiple mounting holes 22, such as two, three or more. Multiple mounting holes 22 are helpful to enhance the stability of the connection between the second leaf 20 and the bracket.

[0050] In one embodiment of the present application, see Figure 1 , Figure 2 and Figure 4 Along the center axis Z, a first gasket 30 is arranged between the first sleeve 11 and the second sleeve 21 .

[0051] Optionally, the first gasket 30 is an annular sheet and is sleeved on the deformation sleeve 50 .

[0052] By disposing the first gasket 30 between the first sleeve 11 and the second sleeve 21 , direct contact between the first sleeve 11 and the second sleeve 21 is effectively avoided, which would cause damage due to long-term mutual friction.

[0053] In one embodiment of the present application, see Figure 3 and Figure 4 A third sleeve 14 is also provided on the first leaf 10 . The third sleeve 14 is located along the center axis Z at one end of the second sleeve 21 away from the first sleeve 11 , and the deformation sleeve 50 passes through the third sleeve 14 .

[0054] Specifically, the third sleeve 14 is spaced apart from the first sleeve 11, and the second sleeve 21 is located between the third sleeve 14 and the first sleeve 11, that is, the third sleeve 14, the second sleeve 21, and the first sleeve 11 are sequentially arranged along the center axis Z, and the deformation sleeve 50 is sequentially passed through the third sleeve 14, the second sleeve 21 and the first sleeve 11.

[0055] Optionally, the third sleeve 14 is made of metal, and can be integrally formed or welded with the first leaf 10 .

[0056] By providing the third shaft sleeve 14 , the stability of the rotational connection between the first leaf 10 and the second leaf 20 is effectively enhanced.

[0057] Further, along the central axis Z, a second gasket 40 is disposed between the third sleeve 14 and the second sleeve 21 .

[0058] Optionally, the second gasket 40 is an annular sheet and is sleeved on the deformation sleeve 50 .

[0059] By disposing the second gasket 40 between the third shaft sleeve 14 and the second shaft sleeve 21 , direct contact between the third shaft sleeve 14 and the second shaft sleeve 21 can be effectively avoided, thereby preventing the third shaft sleeve 14 and the second shaft sleeve 21 from being damaged due to long-term mutual friction.

[0060] In one embodiment of the present application, see Figure 2 , Figure 3 and Figure 5 The deformable sleeve 50 includes a plurality of sheets 54 , which are arranged circumferentially around the central axis Z to enclose an inner cavity 53 , and two adjacent sheets 54 tend to move away from each other under the extrusion of the adjustment section 61 .

[0061] Specifically, the length of the sheet 54 extends along the central axis Z, and multiple sheets 54 are circumferentially surrounded by the adjustment section 61 around the central axis Z, and there are circumferential discontinuities between two adjacent sheets 54 along the central axis Z, so that when the adjustment section 61 moves from the first end 51 to the second end 52, the adjustment section 61 can squeeze the two adjacent sheets 54 to have a tendency to move away from each other, so as to increase the friction between the sheet 54 and the first sleeve 11, the second sleeve 21 and the third sleeve 14.

[0062] It should be noted that two adjacent sheets 54 may also be connected by an elastic member, and when the adjustment section 61 moves from the second end 52 to the first end 51, the distance between the two adjacent sheets 54 tends to approach each other under the action of the elastic member.

[0063] In one embodiment of the present application, there are two sheets 54 , the cross-sections of the two sheets 54 are both semicircular, and the two sheets 54 are arranged relatively spaced apart.

[0064] Specifically, the two sheets 54 have the same size, and the cross section of each sheet 54 gradually decreases from the first end 51 to the second end 52 .

[0065] The cooperation between the two semicircular sheets 54 effectively ensures the overall strength of the deformation sleeve 50 , and in the absence of external force, the resistance of the hinge can remain unchanged for a long time.

[0066] In one embodiment of the present application, see Figure 2 and Figure 4The first sleeve 11 is provided with a connecting hole 111, and the shaft body 60 further includes a connecting section 62, which is connected to an end of the adjusting section 61 close to the second end 52, and the connecting section 62 is inserted into the connecting hole 111 and is threadedly connected with the connecting hole 111.

[0067] Optionally, the connecting section 62 is integrally formed with the adjusting section 61. The cross section of the connecting section 62 is smaller than or equal to the minimum cross section of the adjusting section 61. Further, the cross sections of the adjusting section 61 and the connecting section 62 are both circular, the diameter of the adjusting section 61 gradually decreases from the first end 51 to the second end 52, the diameter of the connecting section 62 remains unchanged from the first end 51 to the second end 52, and the diameter of the connecting section 62 is smaller than or equal to the minimum diameter of the adjusting section 61.

[0068] The connecting hole 111 is a threaded hole, and the connecting section 62 is provided with an external thread, so that after the connecting section 62 is inserted into the connecting hole 111, it can be threadedly connected with the connecting hole 111. In this way, the shaft body 60 can be rotated to make the shaft body 60 move relative to the deformation sleeve 50 along the center axis Z from the first end 51 to the second end 52 or from the second end 52 to the first end 51.

[0069] Furthermore, an adjustment hole 611 is provided at one end of the adjustment section 61 close to the first end 51 .

[0070] The adjustment hole 611 is a square hole, a cross hole or a slotted hole. The user can insert a tool into the adjustment hole 611 and cooperate with the adjustment hole 611 to rotate the shaft 60. The tool can be a wrench or a screwdriver.

[0071] By providing an adjustment hole 611 at one end of the adjustment section 61 close to the first end 51 , it is convenient to insert a tool to rotate the shaft body 60 , which helps to improve the convenience of operation.

[0072] The present application also provides a lamp device, including a lamp, a bracket and a hinge of any of the above embodiments, wherein one of the first leaf 10 and the second leaf 20 is connected to the lamp, and the other is connected to the bracket.

[0073] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
