Description

Technical Field

[0001] The utility model belongs to the technical field of outdoor lamps and relates to a height-adjustable outdoor lamp. Background Art

[0002] As the name suggests, outdoor lights are lighting fixtures exposed outdoors. They can usually be designed and installed in combination with surrounding roads, landscapes, and buildings to achieve a unity of functionality and artistry. In actual use, the height of the lamp body must be adjusted based on the requirements of the illumination range, so a height adjustment mechanism will be designed.

[0003] For example, a desk lamp disclosed in the patent with application publication number CN104344269A includes a lamp head, a lamp pole and a lamp holder. The lamp pole is composed of two support rods (a first support rod and a second support tube) in a set. A deformable protrusion is provided on the second support tube. A clamping device is provided at the connecting position between the first support rod and the second support tube. The first support rod and the second support tube are fixed by tightening the clamping device so that the clamping device compresses the elastic protrusion to clamp the first support rod.

[0004] The above device can adjust the height of the lamp head by relative movement of the first support rod and the second support tube, but there are still shortcomings: the clamping device will be unlocked first when adjusting the height. When the user applies force to lift the first support rod, it is very easy to pull out the entire first support rod due to difficulty in estimating the stroke, resulting in separation of components. Summary of the invention

[0005] The utility model aims at the above-mentioned problems existing in the prior art and provides a height-adjustable outdoor lamp. The technical problem to be solved by the utility model is that components of the prior lamps are easily separated when the lamps are adjusted in height.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A height-adjustable outdoor lamp, comprising a lifting rod and a lower tube body, both of which are vertically arranged, the upper end of the lifting rod being connected to the lamp body, the upper end of the lower tube body being provided with a cylindrical clamping sleeve, the lifting rod being inserted into the clamping sleeve, the outer periphery of the clamping sleeve being threadedly connected with a rotating sleeve which can press the clamping sleeve to the outer periphery of the lifting rod to achieve locking by rotation, characterized in that the outer periphery of the lower end of the clamping sleeve is provided with a snap-fitting protrusion, the inner wall of the lower tube body is provided with a positioning slot, the lower end of the clamping sleeve is inserted into the lower tube body and the snap-fitting protrusion is positioned and embedded in the positioning slot, the lower end of the lifting rod is provided with a trumpet-shaped limiting flange arranged circumferentially with the large end facing downward, and the outer diameter of the limiting flange is larger than the inner diameter of the clamping sleeve.

[0008] The lamp body for emitting illumination light is installed on the upper end of the lifting rod to realize high-altitude illumination. The lifting rod can realize the adjustment of the height of the lamp body by vertically moving relative to the lower tube body. When the rotating sleeve is tightened relative to the clamping sleeve, the inner wall of the rotating sleeve can gradually compress the clamping sleeve to contract radially inwardly and then clamp the lifting rod, so that the lifting rod and the lower tube body are fixed. It belongs to the prior art. By arranging a clamping boss on the outer periphery of the lower end of the clamping sleeve, and arranging a positioning slot hole on the inner wall of the lower tube body to cooperate with the clamping boss for positioning, the installation is convenient and the clamping sleeve will not easily fall out of the lower tube body. The lower end of the lifting rod is provided with a trumpet-shaped limiting edge with a large end facing downward in the circumferential direction. In this way, when the lifting rod moves to the highest point, the upper surface of the limiting edge will collide with the lower end of the clamping sleeve to form a limit, preventing the lifting rod from falling out of the lower tube body. At the same time, when the limiting edge is subjected to a large force, the trumpet-shaped surface will produce a radial expansion of the clamping sleeve, thereby causing the clamping boss to deviate outward, effectively reducing the probability of the clamping sleeve falling out, and ensuring that the lifting rod will not separate from the lower tube body during the height adjustment process.

[0009] In the above-mentioned height-adjustable outdoor lamp, the middle section of the clamping sleeve has a positioning ring arranged around the circumference, and the positioning ring abuts against the upper end surface of the lower tube body. In this way, the positioning ring can provide positioning support for the clamping sleeve, ensuring that the clamping sleeve will not slide into the lower tube body under the downward force. At the same time, when the clamping sleeve is mounted on the lower tube body, there is no need to confirm the position of the clamping protrusion. After the clamping sleeve is inserted into the lower tube body, the positioning ring reaches the abutting position and then the clamping sleeve is rotated. After hearing a click sound, it means that the clamping protrusion and the positioning slot are in place, which is convenient for installation.

[0010] In the above-mentioned height-adjustable outdoor lamp, the part of the clamping sleeve located inside the lower tube body is in the shape of a cone with a small diameter end facing downward, and a gap is left between the outer periphery of the lower end of the clamping sleeve and the inner wall of the lower tube body. In this way, the lower end of the clamping sleeve can be guided when inserted into the lower tube body, so that the assembly resistance is smaller and the assembly is labor-saving. At the same time, the gap between the outer periphery of the lower end of the clamping sleeve and the inner wall of the lower tube body allows the clamping sleeve to be fully offset when the limit flap opens the clamping sleeve, thereby ensuring that the clamping protrusion moves outward at this time, and then the clamping sleeve is always in a stable position, ensuring that the lifting rod will not separate from the lower tube body during the height adjustment process.

[0011] In the above-mentioned height-adjustable outdoor lamp, the lifting rod is a hollow pipe, and the outer periphery of the lifting rod has an annular ridge formed by radially outward arching, and the vertical spacing dimension of the annular ridge and the limit flange is equivalent to the vertical spacing dimension of the clamping protrusion and the lower end surface of the clamping sleeve. This is conducive to achieving a lightweight design while ensuring the support strength of the lifting rod. The annular ridge can provide support for the clamping protrusion from the inside when the limit flange abuts against the lower end of the clamping sleeve, effectively preventing the clamping protrusion from shrinking and dislocating due to external force when the lifting rod is adjusted to the highest position, resulting in separation.

[0012] In the above-mentioned height-adjustable outdoor lamp, the lower edge of the clamping sleeve is subjected to rounded transition processing, which is helpful to avoid scratching of the limit flange when colliding with the lower end of the clamping sleeve, and is helpful to ensure the structural stability of the limit flange.

[0013] In the above-mentioned height-adjustable outdoor lamp, the lower end of the lower tube body is fixedly connected with a vertically arranged ground-breaking rod with the tip facing downward, the lifting rod and the lower tube body are both metal parts, and the clamping sleeve and the ground-breaking rod are both plastic parts. The ground-breaking rod is conducive to directly applying force outdoors to insert the lower tube body deep into the ground to achieve fixation, the lifting rod is a metal part, which is conducive to ensuring the stability of the shape of the limit flap, and the ground-breaking rod is a plastic part, which is conducive to the overall lightweight design.

[0014] Compared with the prior art, the advantages of the utility model are as follows:

[0015] The height-adjustable outdoor lamp can be installed with the lower tube body by a convenient snap-on connection through the holding sleeve, and the lifting rod will not be separated from the lower tube body due to excessive force when the user adjusts the height, and the adjustment structure has better stability.
