Description

Technical Field

[0001] This utility model relates to an LED floor lamp, specifically an LED floor lamp with a lifting mechanism and a multi-angle adjustable structure. Background Technology

[0002] LED floor lamps are a common lighting device in daily life and work, widely used in living rooms, bedrooms, studies, and other places. However, existing LED floor lamps have some shortcomings in use. Most LED floor lamps have a fixed height and cannot be adjusted according to different usage scenarios and needs. For example, a lower lighting height is needed for reading, while a higher lighting height may be needed to create ambiance. Fixed-height floor lamps cannot meet these diverse needs. At the same time, the angle adjustment of the lamp head of existing LED floor lamps is also limited. They are either not adjustable at all or cannot be stably oriented after adjustment, resulting in a limited lighting range and angle, and failing to focus the light well on the desired area, causing many inconveniences for users.

[0003] To address the aforementioned issues, this invention proposes an LED floor lamp with a height-adjustable mechanism and a multi-angle adjustable structure, enabling flexible height adjustment and free adjustment of the lamp head angle to meet the lighting needs of different users in various scenarios.

Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model. Obviously, the embodiments described in this utility model are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0035] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0036] Example 1: The specific structure of this utility model is as follows:

[0037] Please refer to the appendix. Figure 1-6 This utility model discloses an LED floor lamp with a lifting mechanism and a multi-angle adjustable structure, comprising a base 20 as a counterweight, a support portion fixed to the base 20, and a lamp head 100 connected to the support portion. The base 20 is relatively heavy and acts as a counterweight placed on the ground. The seat surface of the base 20 is connected to a post head 201 by screws.

[0038] The support portion includes:

[0039] A column 131 is fixed to the base 20. The lower end of the column 131 is fitted onto the pile head 201 and fixed by the first screw. A wire outlet hole is provided on one side of the column 131. The wire of the wire 12 with plug passes through the outlet hole and enters the interior of the column 131.

[0040] The lifting mechanism installed on the column 131 and at least one lifting rod 141 connected to the lifting mechanism, such as Figure 3 As shown, there are two lifting rods 141. The lifting mechanism has a clamping device that can position and release the lifting rods 141. The lamp head 100 is rotatable and can be oriented after rotation to the upper end of the lifting rods 141.

[0041] The column 131 has an open upper cavity with a vertical guide structure inside. The guide structure has two protruding strips on opposite sides of the cavity, and a slide is formed between the two protruding strips on the same side.

[0042] The lifting mechanism includes:

[0043] A limiting bracket 132 is fixed in the lower region of the straight cavity. A constant voltage power supply 133 is installed on the side of the limiting bracket 132. The circuit board of the constant voltage power supply 133 is connected to the wire.

[0044] A movable slider 142 is installed in the straight cavity, the slider 142 moves along the guide structure, and the lower end of the lifting rod 141 is fixed to the slider 142;

[0045] At least one spring 144, one end of which is connected to the lower end of the slider 142, and the other end of which is fixed to the limiting bracket 132, such as... Figure 3 As shown, spring 144 has two springs.

[0046] The clamping device includes:

[0047] A clamping device bracket 1331 is fixed to the upper cavity opening of the straight cavity. The upper end face of the clamping device bracket 1331 has a protruding clamping part, and the clamping part is provided with a first clamping groove.

[0048] The locking block 1334 has a second clamping groove that is disposed opposite to the first clamping groove. The locking block 1334 is connected to the clamping part by screws so that the first clamping groove and the second clamping groove form a cavity for the lifting rod 141 to pass through.

[0049] The cavity contour matches the outer peripheral surface of the lifting rod 141, that is, the shape of the lifting rod 141 matches the cavity contour. In this embodiment, the lifting rod 141 is set as a circular lifting rod.

[0050] The lifting rod 141 is fitted with a protective rubber ring 1333 and the protective rubber ring 1333 is located in the cavity area. The function of the protective rubber ring 1333 is to increase the friction between the lifting rod 141 and the protective rubber ring 1333. When the first clamping groove and the second clamping groove are clamped together, the lifting rod 141 is fixed and no longer moves up and down.

[0051] The clamping device is covered by a protective cover 134, which is fitted over the lifting rod 141 and is movable. The protective cover 134 serves two purposes: firstly, to be aesthetically pleasing and prevent the clamping device from being exposed; and secondly, to accommodate the remote control 19. The protective cover 134 also has an upper-opening groove for accommodating the remote control 19.

[0052] The protective cover 134 is provided with a through hole that is opposite to the screw. The through hole is for the convenience of a screwdriver to pass through, which is used to tighten and loosen the screw so that the locking block 1334 locks and loosens the lifting rod 141.

[0053] Example 2:

[0054] The following is the lifting process of the LED floor lamp of this utility model: When it is necessary to adjust the height of the LED floor lamp, first operate the clamping device: loosen the screw connecting the clamping device bracket 1331 and the locking block 1334 with a screwdriver through the through hole on the protective cover 134. At this time, the clamping force of the cavity formed by the first clamping groove and the second clamping groove on the lifting rod 141 disappears, and the lifting rod 141 is in a movable state. Under the action of the lifting mechanism, the lifting of the lifting rod 141 is achieved by the movement of the slider 142 along the guide structure in the straight cavity of the column 131. In the guide structure, the protrusions on the opposite side of the straight cavity form a slide, and the slider 142 slides smoothly along the slide. The spring 144 connected to the lower end of the slider 142 will generate elastic force to assist the movement according to the lifting direction: when the lifting rod 141 is lifted upward, the compressed spring 144 resets and generates elastic force, generating an upward elastic force to assist the lifting; after the lifting rod 141 is adjusted to the required height, tighten the screw of the clamping device again with a screwdriver to tighten the first clamping groove and the second clamping groove. Because the cavity contour matches the outer circumference of the lifting rod 141, and the protective rubber ring 1333 on the outer sleeve of the lifting rod 141 can increase the friction, the lifting rod 141 is firmly positioned, and the height adjustment is completed.

[0055] Example 3:

[0056] like Figure 1 As shown, the rotatable and directional structure of the lamp head 100 and the lifting rod 141 is achieved by setting a damping shaft at the connection between the lamp head 100 and the lifting rod 141. The damping shaft enables multi-angle adjustment. When the illumination angle of the lamp head 100 needs to be adjusted, an external force is applied to rotate the lamp head 100. The damping shaft will generate appropriate damping force as it rotates, ensuring a smooth and controllable rotation process. Once the lamp head 100 has rotated to the target angle, the external force is removed. The damping characteristics of the damping shaft will keep the lamp head 100 at that angle, achieving directional fixation. This structure allows the lamp head 100 to rotate in multiple directions within a certain range, meeting the lighting angle requirements of different scenarios.

[0057] like Figure 1 As shown, the lamp head 100 can rotate 87 degrees upward from the horizontal or 87 degrees downward, that is, the lamp head 100 of this utility model can rotate within a range of at least 174 degrees.

[0058] In summary, this utility model, through the inclusion of a height-adjustable mechanism, enables flexible height adjustment of the LED floor lamp. Users can release the lifting rod by adjusting the clamping device, then move the rod up or down to the desired height, and finally reposition it using the clamping device, thus meeting the needs for different lighting heights in various scenarios. The lamp head is connected to the lifting rod via a damping shaft, allowing for multi-angle rotation and stable orientation after rotation. This ensures precise projection of light onto the desired area, improving the targeting and effectiveness of the lighting. The sliding groove on the protective cover can store the remote control, preventing loss and providing convenience for users. The entire device has a reasonable structural design, is simple and convenient to operate, has tight fit between components, good stability, and a long service life.

Any equivalent structural or procedural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
