[0003] At present, there are many types of spotlights on the market, and the application scenarios are different. For example, publication number CN209229515U discloses an embedded stretchable spotlight, including an outer shell, a connecting pin and a stretchable base; wherein the spotlight body can move freely up and down in the outer shell and the baffle, and the outer wall of the stretchable base is just tangent to the inner groove wall of the outer shell, so that the stretchable base is always difficult to detach from the outer shell, so as to achieve the purpose of pulling the spotlight body. However, when the stretchable spotlight is used for a long time, the long-term stretching operation reduces the friction between the outer wall of the stretchable base and the inner groove wall of the outer shell. Even if the lamp body is moved up and down to a predetermined distance, the lamp body will move down under the action of gravity, resulting in the lamp body being unable to maintain the illumination at the specified height.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present disclosure. The terms used herein in the specification of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0033] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0034] See also Figure 1 and Figure 2, which is a stretching spotlight structure 10 of an embodiment of the utility model, includes an outer tube 100, a clamping assembly 200 and a stretching mechanism 300. The outer tube 100 is provided with an abutting retaining ring 110, and the abutting retaining ring 110 is arranged on the inner circumferential wall of the outer tube 100 to form a accommodating cavity 101 and a through opening 102 inside the outer tube 100. The stretching mechanism 300 is movably arranged in the accommodating cavity 101, and the clamping assembly 200 is installed on the outer circumferential wall of the outer tube 100 and is arranged adjacent to the through opening 102.

[0035] like Figures 2 to 5 As shown, in one embodiment, the stretching spotlight structure 10 also includes a damping component 400, and the stretching mechanism 300 includes a stretching base 310 and a stretching component 320, wherein the stretching base 310 is located in the accommodating cavity 101, so that the stretching component 320 pushes the stretching base 310 to move in a sliding track (hereinafter referred to as a sliding track) formed between the inner top of the outer cylinder 100 and the abutting retaining ring 110, and the stretching base 310 is provided with a limiting groove 3101, and the damping component 400 is arranged in the limiting groove 3101 and abuts against the inner wall of the outer cylinder 100, so that the two ends of the damping component 400 abut against the bottom of the limiting groove 3101 and the inner wall of the outer cylinder 100, thereby achieving the effect of interference fit between the damping component 400 and the inner wall of the outer cylinder 100.

[0036] like Figure 2 and Figure 5 As shown, in one embodiment, the stretching assembly 320 includes a stretching rod 321 and a connecting seat 322 connected to each other; the connecting seat 322 is connected to the stretching base 310, and one side of the connecting seat 322 is used to connect the lighting assembly 21. Specifically, one side of the connecting seat 322 is screwed to the lighting assembly 21 through a screw 22. The outer cylinder 100 is provided with a through hole 103, and the through hole 103, the accommodating cavity 101 and the through port 102 are sequentially connected, and the stretching rod 321 is inserted through the through hole 103. In this embodiment, the maximum cross-sectional outer diameter of the stretching base 310 is greater than the inner diameter of the abutting retaining ring 110, so that the stretching rod 321 pushes the stretching base 310 to move a distance downward along the sliding track through the connecting seat 322 and abuts against the abutting retaining ring 110. When the stretching base 310 abuts against the abutting retaining ring 110, part of the structure of the stretching base 310 and the connecting seat 322 are located in the through port 102, and the stretching rod 321 is always inserted through the through hole 103.

[0037] In this embodiment, the damping assembly 400 is located in the limiting groove 3101 and abuts against the inner wall of the outer cylinder 100, so that the damping assembly 400 and the inner wall of the outer cylinder 100 are in interference contact. When an external force such as human power is applied to the stretching rod 321, the stretching base 310 moves up and down in the accommodating cavity 101, thereby driving the lighting assembly 21 to move up and down. When the external force disappears, the friction force generated between the damping assembly 400 and the inner wall of the outer cylinder 100 can prevent the stretching mechanism 300 from continuing to move down, so that it can be suspended, so that the lighting assembly 21 can maintain a certain height for irradiation, and thus the reliability of adjusting the irradiation height of the lamp is better. Of course, after installing the lighting assembly 21, an external force can also be applied to the lighting assembly 21 to stretch or push it, so that the stretching base 310 moves along with the lighting assembly 21 in the sliding track, and the stretching assembly 320 also moves along with the movement of the stretching base 310 and the lighting assembly 21.

[0038] Further, the number of the damping components 400 and the limiting grooves 3101 are both multiple, and each damping component 400 is respectively located in the limiting grooves 3101 and abuts against the inner wall of the outer tube 100, so that when the external force disappears, each damping component 400 keeps the tension base 310 suspended by its damping effect, so that the lamp body can be suspended without upward and downward deviation. Further, the multiple is three.

[0039] like Figure 2 and Figure 3 As shown, in one embodiment, the damping assembly 400 includes a damping member 410 and a spring member 420. The spring member 420 is disposed around the outer wall of the damping member 410. The spring member 420 abuts against the inner wall of the limiting groove 3101 and the inner wall of the outer cylinder 100 respectively. The damping member 410 is located in the limiting groove 3101 and abuts against the inner wall of the outer cylinder 100. It can be understood that when the spring member 420 is disposed around the outer wall of the damping member 410, both ends of the damping member 410 abut against the inner wall of the limiting groove 3101 and the inner wall of the outer cylinder 100. Since the outward elastic force of the spring member 420 is blocked by the inner wall of the outer cylinder 100, the damping member 410 is suspended at any position in the sliding track to ensure that the lighting height of the lighting assembly 21 remains unchanged.

[0040] like Figure 4 and Figure 5 As shown, in one embodiment, the stretching base 310 includes a base body 311 and a spiral member 312. The base body 311 is provided with a connecting abutment hole 3111 and a spiral groove 3112. The screw connection portion of the spiral member 312 is located in the spiral groove 3112 so that the spiral member 312 is screwed to the base body 311. The two ends of the damping assembly 400 respectively abut against the inner wall of the outer cylinder 100 and the outer peripheral wall of the spiral member 312.

[0041] Furthermore, the base body 311 is provided with an abutment channel, which is connected to the abutment hole 3111, so that when the damping assembly 400 is located in the abutment channel, its two ends respectively abut against the outer wall of the spiral member 312 and the inner wall of the outer tube 100 to achieve an interference abutment effect. At this time, a limiting groove 3101 is formed between the abutment channel and the outer wall of the spiral member 312.

[0042] Furthermore, if Figure 4 As shown, the spiral member 312 is provided with an avoidance hole 3121 , which is communicated with the spiral groove 3112 . The spiral member 312 separates the abutment hole 3111 and the avoidance hole 3121 . The stretching rod 321 is sequentially passed through the avoidance hole 3121 and the spiral groove 3112 and connected to the connecting seat 322 .

[0043] like Figures 4 to 6 As shown, in one embodiment, the connecting seat 322 is provided with a connecting hole 322a, and the connecting seat 322 includes a first connecting portion 3221, a transition portion 3222 and a second connecting portion 3223 that are connected to each other. The stretching rod 321 is sequentially passed through the air avoidance hole 3121, the spiral groove 3112 and the connecting hole 322a and is connected to the second connecting portion 3223; the base body 311 is also provided with a transition hole 3113, the abutting hole 3111, the spiral groove 3112 and the transition hole 3113 are sequentially connected, the first connecting portion 3221 abuts against the bottom of the spiral groove 3112, the transition portion 3222 is located in the transition hole 3113, and the second connecting portion 3223 abuts against the outer side of the base body 311, and is used to connect the lighting assembly 21. When the lamp needs to be raised, the stretching rod 321 drives the connecting seat 322 to rise. At this time, the second connecting part 3223 drives the lighting assembly 21 to move upward a certain distance; when the lamp needs to be lowered a certain distance, the stretching rod 321 pushes the connecting seat 322 to move downward. At this time, the second connecting part 3223 drives the lighting assembly 21 to move downward a certain distance, and the first connecting part 3221 contacts the bottom of the spiral groove 3112.

[0044] In one embodiment, the cross-sectional diameter of the second connection portion 3223 is greater than the cross-sectional diameter of the first connection portion 3221. Further, the cross-sectional diameter of the second connection portion 3223 and the cross-sectional diameter of the first connection portion 3221 are both greater than the cross-sectional diameter of the transition portion 3222, so that the lamp will not be separated from the stretch base 310 when it is raised or lowered a certain distance.

[0045] like Figure 2 As shown, in one embodiment, the outer tube 100 is provided with a buffer ring 120, which is disposed on the inner circumferential wall of the outer tube 100 adjacent to the through hole 103. It can be understood that when the lamp is raised to the inner top of the outer tube 100, one side of the stretching base 310 abuts against the buffer ring 120, so that the buffer ring 120 plays a buffering role on the stretching base 310.

[0046] like Figure 1 As shown, in one embodiment, the clamping assembly 200 includes a clamping piece 210 and a clamping truncated cone 220. The clamping truncated cone 220 is mounted on the outer peripheral wall of the outer cylinder 100 and is arranged adjacent to the through opening 102. The clamping piece 210 is mounted on the outer wall of the clamping truncated cone 220. Further, the clamping piece 210 is used to clamp to the groove wall of the installation groove of the building main body when the stretchable spotlight 20 is installed, and the clamping truncated cone 220 is used to clamp with the building main body when the stretchable spotlight 20 is installed in the installation groove of the building main body to fix the stretchable spotlight 20.

[0047] like Figure 1 As shown, in one embodiment, the card plate 210 is provided with a relief opening 211, please refer to Figure 5 The clamping truncated cone 220 is provided with a convex column 221, and the convex column 221 is correspondingly arranged in the avoidance opening 211. It can be understood that when the stretchable spotlight 20 is installed in the main body of the building, the clamping piece 210 is bent into the installation groove of the main body of the building and abuts against the groove to further fix the stretchable spotlight 20 to prevent the stretchable spotlight 20 from falling. At this time, the convex column 221 passes through the avoidance opening 211.

[0048] like Figure 7 and Figure 8 As shown, the present disclosure further provides a stretchable spotlight 20, including a lighting assembly 21 and a stretchable spotlight structure 10 of any of the above embodiments, wherein the lighting assembly 21 is mounted on one side of a connecting seat 322, and specifically, the connecting seat 322 is screwed to the lighting assembly 21 by means of screws 22. In this embodiment, the lighting assembly 21 is mounted on one side of the second connecting portion 3223.

[0049] Compared with the prior art, the present invention has at least the following advantages:

[0050] The above-mentioned stretch spotlight structure 10 is provided with a damping component 400, which is located in the limiting groove 3101 and abuts against the inner wall of the outer tube 100, so that the damping component 400 and the inner wall of the outer tube 100 are in interference fit. When an external force such as human power is applied to the stretching rod 321, the stretching base 310 moves up and down in the accommodating cavity 101, thereby driving the lighting component 21 to move up and down. When the external force disappears, the friction force of the damping component 400 on the inner wall of the outer tube 100 can prevent the stretching mechanism 300 from continuing to move downward, causing it to hover, so that the lighting component 21 can maintain a certain height for irradiation, thereby having better reliability in adjusting the irradiation height of the lamp.

[0051] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the disclosed patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the disclosed patent shall be subject to the attached claims.
