Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a lifting tree-shaped light fixture. Background Technology

[0002] Christmas lights are an important element of Christmas, primarily serving to enhance the festive atmosphere. However, existing Christmas lights suffer from the following problems: First, most commercially available Christmas tree lights lack height adjustment capabilities, making it difficult to meet users' needs for lights at different heights. Second, in existing technologies, some height-adjustable Christmas tree lights typically use two threaded sleeves connected together, with the height of the tree adjusted by rotating the sleeves. However, one end of the light strip is usually fixed to one of the sleeves, while the other end is fixed to the base. Rotating the sleeves causes the light strip to tangle, requiring the light strip to be disassembled before adjusting the tree's height, which significantly impacts assembly efficiency. Summary of the Invention

[0003] To address the aforementioned problems, this utility model provides a height-adjustable and structurally stable lifting tree-shaped light fixture.

[0004] The technical solution of this utility model is as follows: A lifting tree-shaped light fixture includes a fixed base, a first sleeve fixedly connected to the fixed base, a second sleeve movably connected to the first sleeve, a fixing component connecting the first and second sleeves, and a light fixture strip connecting the second sleeve and the fixed base. The diameter of the second sleeve is smaller than the diameter of the first sleeve. The fixing component includes two sliding plates slidably connected to the fixed base, a positioning plate fixedly connected to the sliding plates, and several positioning shafts fixedly connected to the positioning plates. The first sleeve has a connecting groove, and the sliding plates are slidably connected to the connecting groove. The second sleeve has several positioning holes, which are symmetrically arranged on both sides of the second sleeve and evenly arranged along the axial direction of the second sleeve. The shape and size of the positioning holes are adapted to the positioning shafts. The positioning plate is located between the inner wall of the first sleeve and the outer wall of the second sleeve, and the distance between the inner wall of the first sleeve and the outer wall of the second sleeve is greater than the length of the positioning shaft.

[0005] Using the above technical solution, when the height of the Christmas tree needs to be adjusted, first slide the two sliding plates a certain distance in opposite directions to disengage the positioning shaft from the positioning hole. Then, pull the second sleeve vertically. After adjusting to the appropriate height, move the two sliding plates in opposite directions. The positioning plate and positioning shaft move with the sliding plates, allowing the positioning shaft to enter the corresponding positioning hole, thereby restricting the vertical movement of the second sleeve and stabilizing the height of the Christmas tree lights. Compared with the traditional sleeve adjustment method, this device does not require rotating the sleeve and can quickly adjust the overall height of the Christmas tree lights. It does not cause knots in the light strips and does not require disassembling the light strips, which can greatly improve assembly efficiency.

[0006] A further feature of this invention is that the positioning plate is arc-shaped, and the fixed base is provided with two limiting grooves, with two sliding plates slidably connected to the two limiting grooves respectively.

[0007] By adopting the above technical solution, since the positioning plate is arc-shaped, the range of motion of the positioning plate can be increased, thereby extending the length of the positioning shaft and increasing the supporting force of the positioning shaft on the second sleeve. In addition, since the fixed base is provided with two limiting grooves, and the two sliding plates are slidably connected to the two limiting grooves respectively, it can be ensured that the sliding plates will not shift during movement, and that the positioning shaft can be accurately inserted into the positioning hole.

[0008] A further feature of this invention is that a return spring is provided between the two positioning plates, and the inner diameter of the positioning plate is adapted to the outer diameter of the second sleeve. When the return spring is in its initial state, the positioning shaft is located inside the positioning hole.

[0009] With the above technical solution, since there is a return spring between the two positioning plates, after the height adjustment of the Christmas tree lights is completed, it is only necessary to release the two sliding plates. Through the reaction force of the return spring, the two sliding plates can be quickly reset and the positioning shaft can be inserted into the positioning hole. This can further improve the height adjustment efficiency and assembly efficiency of the Christmas tree lights.

[0010] A further feature of this invention is that the fixed base has a threaded hole, the sliding plate has a strip hole, and the sliding plate and the fixed base can be fixedly connected by a fixing bolt. The diameter of the fixing bolt is adapted to the diameter of the threaded hole and the width of the strip hole, respectively.

[0011] By adopting the above technical solution, since the fixed base is provided with threaded holes and the sliding plate is provided with strip holes, after the height adjustment is completed, the fixing bolt is threaded into the threaded holes, thereby fixing the sliding plate and preventing the second sleeve from being unable to be fixed due to the sliding plate sliding. This can further improve the overall structural stability of the Christmas tree lights. Attached Figure Description

[0014] like Figure 1 As shown, a retractable tree-shaped light fixture includes a fixed base 1, a first sleeve 2 fixedly connected to the fixed base 1, a second sleeve 3 movably connected to the first sleeve 2, a fixing assembly 4 connecting the first sleeve 2 and the second sleeve 3, and a light fixture strip 5 connecting the second sleeve 3 and the fixed base 1. The diameter of the second sleeve 3 is smaller than the diameter of the first sleeve 2. The fixing assembly 4 includes two sliding plates 6 slidably connected to the fixed base 1, a positioning plate 7 fixedly connected to the sliding plates 6, and several brackets fixedly connected to the positioning plate 7. The positioning shaft 8 is provided. The first sleeve 2 is provided with a connecting groove 9. The sliding plate 6 is slidably connected to the connecting groove 9. The second sleeve 3 is provided with a plurality of positioning holes 10. The positioning holes 10 are symmetrically arranged on both sides of the second sleeve 3 and are evenly arranged along the axial direction of the second sleeve 3. The shape and size of the positioning holes 10 are adapted to the positioning shaft 8. The positioning plate 7 is located between the inner wall of the first sleeve 2 and the outer wall of the second sleeve 3. The distance between the inner wall of the first sleeve 2 and the outer wall of the second sleeve 3 is greater than the length of the positioning shaft 8.

[0015] When the height of the Christmas tree needs to be adjusted, first slide the two sliding plates 6 a certain distance in opposite directions to disengage the positioning shaft 8 from the positioning hole 10. Then pull the second sleeve 3 vertically. After adjusting to the appropriate height, move the two sliding plates 6 in opposite directions. The positioning plate 7 and positioning shaft 8 move with the sliding plates 6, so that the positioning shaft 8 enters the corresponding positioning hole 10, thereby restricting the vertical movement of the second sleeve 3 and stabilizing the height of the Christmas tree lights. Compared with the traditional sleeve adjustment method, this device does not require rotating the sleeve and can quickly adjust the overall height of the Christmas tree lights. It will not cause the light strip 5 to get tangled or other problems, and there is no need to disassemble the light strip 5, which can greatly improve the assembly efficiency.

[0016] The positioning plate 7 is arc-shaped, and the fixed base 1 is provided with two limiting grooves 11. The two sliding plates 6 are slidably connected to the two limiting grooves 11 respectively.

[0017] Since the positioning plate 7 is arc-shaped, its range of motion can be increased, thereby extending the length of the positioning shaft 8 and increasing the supporting force of the positioning shaft 8 on the second sleeve 3. In addition, since the fixed base 1 is provided with two limiting grooves 11, and the two sliding plates 6 are slidably connected to the two limiting grooves 11 respectively, it can be ensured that the sliding plates 6 will not shift during movement, and that the positioning shaft 8 can be accurately inserted into the positioning hole 10.

[0018] A return spring 12 is provided between the two positioning plates 7. The inner diameter of the positioning plate 7 is adapted to the outer diameter of the second sleeve 3. When the return spring 12 is in the initial state, the positioning shaft 8 is located inside the positioning hole 10.

[0019] Since a return spring 12 is provided between the two positioning plates 7, after the height adjustment of the Christmas tree lights is completed, it is only necessary to release the two sliding plates 6. The reaction force of the return spring 12 can help the two sliding plates 6 to quickly return to their original position, and the positioning shaft 8 can be inserted into the positioning hole 10. This can further improve the height adjustment efficiency and assembly efficiency of the Christmas tree lights.

[0020] The fixed base 1 is provided with a threaded hole 13, and the sliding plate 6 is provided with a strip hole 14. The sliding plate 6 and the fixed base 1 can be fixedly connected by a fixing bolt 15. The diameter of the fixing bolt 15 is adapted to the diameter of the threaded hole 13 and the width of the strip hole 14, respectively.

[0021] Since the fixed base 1 has a threaded hole 13 and the sliding plate 6 has a strip hole 14, after the height adjustment is completed, the fixing bolt 15 is threaded into the threaded hole 13, thereby fixing the sliding plate 6 and preventing the second sleeve 3 from being unable to be fixed due to the sliding plate 6 sliding. This can further improve the overall structural stability of the Christmas tree lights.
