[0035] First see Figures 1 to 4 The present invention provides a joint lamp 10, which can adjust different illumination angles so that users can use it in scenes with insufficient light. Specifically, the joint lamp 10 includes a light source 100 and a plurality of joint tubes 200 connected end to end. Each joint tube 200 has a first end face 210 and a second end face 220 that are axially opposite to each other. In the same joint tube 200, the normal of the first end face 210 and the normal of the second end face 220 are set at an angle. In any two adjacent joint tubes 200, the first end face 210 of one joint tube 200 is set opposite to the second end face 220 of the other joint tube 200, and the two joint tubes 200 rotate around the normal of the two relative end faces. The joint lamp 10 is also divided into connected The support end 300 and the lighting end 400 both include multiple sections of joint tubes 200 connected end to end. Any two adjacent sections of the joint tubes 200 in the support end 300 can rotate relative to each other so that the support end 300 switches to a coiled state to support the lighting end 400. The light source 100 is arranged at the lighting end 400. By rotating any two adjacent joint tubes 200 in the lighting end 400, the illumination angle of the light source 100 can be switched and the risk of damage to the joint tube 200 can be reduced. The support end 300 can be switched to different coiled states to meet the support requirements of different usage scenarios.

[0036] refer to Figures 1 to 3 Each joint tube 200 in the support end 300 can rotate relative to another adjacent joint tube 200 to switch to different supporting postures.

[0037] refer to Figure 4The joint tube 200 is bent and extended. The joint tube 200 includes a first branch tube 230 and a second branch tube 240. The first branch tube 230 and the second branch tube 240 are connected to each other, and the connection method can be integral casting. The first end surface 210 is formed at the end of the first branch tube 230 away from the second branch tube 240, and the second end surface 220 is formed at the end of the second branch tube 240 away from the first branch tube 230. The angle between the first branch tube 230 and the second branch tube 240 is φ, and the angle between the normal of the first end surface 210 and the normal of the second end surface 220 is θ. At the same time, φ=θ, and 90°≤φ<180°, 90°≤θ<180°, that is, the first branch tube 230 extends in a straight line and the extension direction is the same as the extension direction of the normal of the first end surface 210, and the second branch tube 240 extends in a straight line and the extension direction is the same as the extension direction of the second end surface 220. The normal extension direction is the same. In addition, ≤φ<180°, 90°≤θ<180° so that after each joint tube 200 is connected in sequence, the entire joint lamp 10 can be roughly expanded linearly, which is convenient for adjusting the illumination angle of the light source 100. In this embodiment, φ=θ=90°, that is, the first branch tube 230 is perpendicular to the second branch tube 240 and the connection between the two is an arc-shaped transition, so that the appearance of each joint tube 200 is more coordinated. It should be noted that in other embodiments, the first branch tube 230 and the second branch tube 240 can also extend in an arc shape to form an appearance of different shapes. In addition, φ may not be equal to θ, that is, the extension direction of the first branch tube 230 is at an angle to the normal extension direction of the first end face 210, and the extension direction of the second branch tube 240 is at an angle to the normal extension direction of the second end face 220.

[0038] refer to Figures 4 to 7 , a connecting piece 500 is also provided in any two adjacent joint tubes 200, and the connecting piece 500 is located between the first end face 210 and the second end face 220 of the two joint tubes 200. The connecting piece 500 includes a rotating section 510 and a clamping section 520 connected to each other. One of the rotating section 510 and the clamping section 520 is fixed to the first end face 210, and the other is fixed to the second end face 220. The rotating section 510 and the clamping section 520 are relatively clamped and can rotate relative to each other in the circumferential direction. It should be noted that in this embodiment, the side walls of the rotating section 510 and the clamping section 520 are both provided with fixing grooves, and the inner wall of the joint tube 200 is protruding with a fixing block, which is embedded in the fixing groove to realize circumferential rotation limitation of the rotating section 510 relative to the first end face 210 and the clamping section 520 relative to the second end face 220.

[0039] The hook 521 is provided with a locking hole 511 on one of the rotating section 510 and the clamping section 520, and a locking hook 521 is provided on the other. There are at least two locking hooks 521 arranged opposite to each other. The locking hook 521 passes through the locking hole 511 and abuts against the opening edge of the locking hole 511, so that the rotating section 510 and the clamping section 520 are clamped together, and the two adjacent joint tubes 200 are connected. In this embodiment, the locking hole 511 is opened in the rotating section 510, and the locking hook 521 is provided in the clamping section 520. The hook 521 extends along the normal direction of the second end face 220. The hook 521 is provided with an inclined surface 5211 and an abutting surface 5212 relative to each other along the locking direction. The inclined surface 5211 is inclined to the axial direction of the locking hole 511, and the abutting surface 5212 is perpendicular to the axial direction of the locking hole 511. When the rotating section 510 and the clamping section 520 are relatively buckled, the locking hole 511 is opened in the rotating section 510, and the locking hook 521 is provided in the clamping section 520. The locking hook 521 extends along the normal direction of the second end face 220. The hook 521 is provided with an inclined surface 5211 and an abutting surface 5212 relative to each other along the locking direction. The inclined surface 5211 is inclined to the axial direction of the locking hole 511, and the abutting surface 5212 is perpendicular to the axial direction of the locking hole 511. When the locking section 520 is engaged, the locking section 520 is pushed along the axial direction of the locking hole 511, and the outer opening edge of the locking hole 511 squeezes the inclined surface 5211 and slides along the inclined surface 5211. At the same time, during the sliding process, the hook 521 is deformed in the direction close to the central axis of the locking hole 511, so that the inclined surface 5211 passes over the locking hole 511. When the inclined surface 5211 slides over the locking hole 511, the hook 521 resumes its deformation. At this time, the abutting surface 5212 is engaged with the edge of the inner opening of the locking hole 511, so that the rotating section 510 and the locking section 520 are limited along the normal direction of the first end face 210. It can be understood that the distance between the two opposite hooks 521 is equal to the radial distance of the locking hole 511, so that the hook 521 will not accidentally detach after being engaged with the inner opening edge of the locking hole 511.

[0040] The clamping section 520 is also provided with a rotating shaft 522, the axial direction of the rotating shaft 522 is the same as the axial direction of the clamping hole 511, the hook 521 is arranged at intervals on the side wall of the rotating shaft 522, the clamping hole 511 is a circular hole structure, the rotating shaft 522 is passed through the clamping hole 511, and the hook 521 is clamped to the inner opening edge of the clamping hole 511. The clamping section 520 rotates circumferentially around the rotating shaft 522 relative to the rotating section 510, so that the two adjacent joint tubes 200 rotate relative to each other around the axis of the rotating shaft 522.

[0041] The rotating shaft 522 is a hollow structure from one end to the other end along its axial direction. The hook 521 is located on the side wall of the rotating shaft 522 near the end of the rotating section 510. The rotating shaft 522 is provided with a deformation notch 5221 between two circumferentially adjacent hooks 521. The deformation notch 5221 extends from the end of the rotating shaft 522 along its axial direction. The deformation notch 5221 divides the rotating shaft 522 into a plurality of deformable arc-shaped plate structures along the circumferential direction. The plurality of hooks 521 are respectively located at a plurality of arc-shaped plate structures. On the plate, when the rotating shaft 522 is pushed to pass through the engaging hole 511, the hook 521 is squeezed by the opening edge of the engaging hole 511, so that the arc plate provided with the hook 521 is deformed synchronously. Compared with the rotating shaft 522 without the deformation notch 5221, the deformation notch 5221 can make the hook 521 more likely to shrink toward the axial direction of the rotating shaft 522 when being squeezed, so that the hook 521 can more easily pass through the engaging hole 511 and engage with the rotating section 510.

[0042] refer to Figures 5 to 7 In any two adjacent joint tubes 200, one of the rotating section 510 and the clamping section 520 is provided with a positioning groove 523, and the other is provided with a positioning piece 512. In this embodiment, the positioning groove 523 is provided on the side of the clamping section 520 close to the rotating section 510, and the positioning piece 512 is located on the side of the rotating member close to the clamping section 520. The positioning piece 512 can be embedded in the positioning groove 523, so that the rotating section 510 and the clamping section 520 are rotated and positioned along the circumferential direction, so that the two adjacent joint tubes 200 can be rotated to a suitable angle. It is convenient to position. It can be understood that the role of the positioning groove 523 and the positioning member 512 is to facilitate the positioning of the two adjacent joint tubes 200 at different angles. In other embodiments, the positioning groove 523 and the positioning member 512 can also be replaced by a damping structure. The damping structure is located between the rotating section 510 and the clamping section 520. When the rotating section 510 and the clamping section 520 are rotated and reach a preset angle, the damping structure can make the rotating section 510 and the clamping section 520 relatively positioned in the absence of external force to prevent the two adjacent joint tubes 200 from accidentally deflecting.

[0043] There are multiple positioning grooves 523, and the multiple positioning grooves 523 are circumferentially arranged along a side of the clamping section 520 close to the rotating section 510, and the arrangement of the multiple positioning grooves 523 are all located on the circumferential rotation path of the positioning member 512. In this embodiment, the positioning member 512 includes a positioning block 5121 and an elastic member 5122. A receiving groove 513 is opened on a side of the rotating section 510 close to the clamping section 520, and the elastic member 5122 is accommodated in the receiving groove 513. The positioning block 5121 is located at the opening of the receiving groove 513. One end of the elastic member 5122 abuts against the bottom wall of the receiving groove 513, and the other end of the elastic member 5122 abuts against the positioning block 5121. The elastic member 5122 is always Finally, it is squeezed to accumulate elastic force and push the positioning block 5121 to snap into the positioning groove 523. When it is necessary to relatively rotate the clamping section 520 and the rotating section 510 to switch the angles of the two joint tubes 200, the inner wall of the positioning groove 523 squeezes the positioning block 5121, and the positioning block 5121 moves to the bottom of the accommodating groove 513 and slides out of the positioning groove 523. The positioning block 5121 squeezes the elastic member 5122 to shrink the elastic member 5122. The rotating member is continuously rotated to rotate the positioning block 5121 to the next adjacent positioning groove 523. The elastic member 5122 recovers part of its deformation and pushes the positioning block 5121 to snap into the positioning groove 523 to switch the positioning angles of the two joint tubes 200.

[0044] It can be understood that the elastic member 5122 can be replaced by two repelling magnets. In addition, the positioning member 512 can also be other structures. For example, the positioning member 512 is a protruding block structure on one side of the rotating end close to the clamping section 520. The block structure can rotate with the rotating section 510 to be clamped into different positioning grooves 523. In order to increase the deformation ability of the block structure, a hollow deformation groove can be set in the center of the block structure.

[0045] In this embodiment, the positioning block 5121 is a spherical structure, and the positioning groove 523 is also a corresponding spherical groove. Multiple positioning grooves 523 are interconnected along the circumferential direction to form a closed ring. The depth of the central groove wall of two adjacent positioning grooves 523 is lower than the groove wall depth at the connection of the two positioning grooves 523. The groove wall edge of the positioning groove 523 to the groove wall center of the positioning groove 523 is transitioned in an arc-shaped surface. The positioning block 5121 slides from one of the positioning grooves 523 to the adjacent other positioning groove 523 along the arc-shaped surface. In the process of the positioning block 5121 switching different positioning grooves 523, the setting of the arc-shaped surface can enable the positioning block 5121 to slide out of the positioning groove 523 smoothly, and the positioning block 5121 is set to be spherical so that the positioning block 5121 will not be stuck during the sliding process, so that the rotation of the two adjacent joint tubes 200 is smoother.

[0046] refer to Figure 8 and Figure 9A plurality of connectors 500 are provided at the connection of the multi-section joint tube 200 , and two adjacent connectors 500 are fixedly connected. The connection between the two connectors 500 can be by snapping, bonding, etc.

[0047] In two adjacent connecting members 500, the rotating section 510 of one connecting member 500 is fastened and connected with the clamping section 520 of the other connecting member 500. Specifically, the rotating section 510 of one connecting member 500 is provided with two relatively spaced fastening hooks 514 on the side facing away from the positioning member 512, and the clamping section 520 of the other connecting member 500 is provided with a fastening plate 524 on the side facing away from the rotating shaft 522. The fastening hooks 514 and the fastening plates 524 are relatively fastened and connected, so that the two adjacent connecting members 500 are fixedly connected. The ends of the fastening hooks 514 are provided with guiding surfaces 5141 and fastening surfaces 5142 that are opposite to each other along the fastening direction. The guiding surface 5141 is inclined to the fastening direction, and the fastening surface 5142 is perpendicular to the fastening direction. The edges of the fastening plates 524 on both sides are protruding with fastenings. The locking block 5241, when the locking hook 514 is locked with the locking plate 524, the locking block 5241 slides along the guide surface 5141 and stretches and squeezes the two locking hooks 514, so that the distance between the two locking hooks 514 increases, and the guide surface 5141 passes over the locking block 5241, and the two locking hooks 514 recover and deform, so that the locking surface 5142 abuts and bites with the locking block 5241, so that the rotating section 510 of one connecting member 500 is locked and connected with the snapping section 520 of the other connecting member 500. It can be understood that the above-mentioned section of the joint tube 200 includes a first branch pipe 230 and a second branch pipe 240 that are perpendicular to each other, and the rotating section 510 of one connecting member 500 is arranged in the first branch pipe 230, and the snapping section 520 of the other connecting member 500 is arranged in the second branch pipe 240.

[0048] refer to Figure 4 The joint lamp 10 also includes a wire 600 and a power switch 700. Each joint tube 200 is a hollow structure with openings at both ends. The interiors of the two adjacent joint tubes 200 are connected. The wire 600 is passed through the interior of the joint tube 200. The wire 600 extends from the support end 300 to the lighting end 400 and is electrically connected to the light source 100. The power switch 700 is connected to the wire 600 and controls the turning on or off of the light source 100. It can be understood that the wire 600 is a flexible conductive material. When the two adjacent joint tubes 200 rotate, the wire 600 rotates with the joint tube 200 and forms a bent state.
