Description

Technical Field

[0001] This utility model relates to the field of floor lamp technology, and in particular to a floor lamp with a rotatable lamp head. Background Technology

[0002] LED lighting fixtures are a general term for LED lamps, referring to appliances that can transmit, distribute, and change the light distribution of LED light sources. They are generally divided into uplight floor lamps and downlight floor lamps, and are usually placed in living rooms and rest areas, used in conjunction with sofas and coffee tables to meet the needs of local lighting and decorative embellishment of the home environment. In some popular modern minimalist home designs, their stylish and unique shapes and ease of use are increasingly sought after by the public. The use of this type of lamp is quite common. In daily life, people need a height-adjustable LED floor lamp that can ensure sufficient light and meet people's needs for light from different directions and angles, thereby improving their quality of life.

[0003] In the prior art, such as Chinese Patent No. CN221724236U, a height-adjustable LED floor lamp is disclosed. This utility model relates to the field of floor lamp technology. This height-adjustable LED floor lamp allows for easy adjustment of the illumination angle by pulling the first connecting member upward, causing the second limiting member to move away from the first limiting member. After the floor lamp angle adjustment is completed, the first connecting member is released, and the second limiting member will re-engage with the first limiting member due to gravity, preventing the illumination direction of the floor lamp from shifting due to collision. This increases the overall stability of the LED floor lamp. Then, the motor drives the threaded rod to rotate, causing the moving block on the surface of the threaded rod to move left and right, thereby enabling the cleaning brush on the fixed base to complete the cleaning work, which facilitates people's daily life and improves their quality of life.

[0004] Although the floor lamp height can be adjusted by loosening the fixing part, which allows one end of the fixing part to detach from the fixing groove on the first fixing rod, and then sliding the second fixing rod up and down, the weight of the second fixing rod itself can easily cause pressure on the hand when turning the knob on the second fixing rod, resulting in hand discomfort. Moreover, this height adjustment method is still not convenient enough, making the adjustment of the floor lamp height not quick and easy. Utility Model Content

[0005] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a floor lamp with a rotatable lamp head.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a floor lamp with a rotatable lamp head, comprising a base, a vertical rod fixedly connected to the surface of the base, a sleeve rod slidably connected to the surface of the vertical rod, a connecting tube fixedly connected to the top end of the sleeve rod, a lamp head body fixedly connected to the other end of the connecting tube, an adjustment hole formed on the surface of the vertical rod, a sleeve fixedly connected to the surface of the sleeve rod, a sliding groove formed inside the sleeve, an insert rod slidably connected inside the sliding groove, the insert rod being inserted into the adjustment hole, a pull rod fixedly connected to the surface of the insert rod, and a spring sleeved on the surface of the pull rod.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: As Figure 1 - Figure 4As shown, this utility model provides a technical solution: a floor lamp with a rotatable lamp head, including a base 1, a vertical rod 2 fixedly connected to the surface of the base 1, a sleeve rod 3 slidably connected to the surface of the vertical rod 2, a connecting tube 4 fixedly connected to the top end of the sleeve rod 3, and a lamp head body 5 fixedly connected to the other end of the connecting tube 4. An adjustment hole 8 is provided on the surface of the vertical rod 2, a sleeve 11 is fixedly connected to the surface of the sleeve rod 3, a sliding groove 13 is provided inside the sleeve 11, an insert rod 14 is slidably connected inside the sliding groove 13, the insert rod 14 is inserted into the adjustment hole 8, and a pull rod 1 is fixedly connected to the surface of the insert rod 14. 6. A spring 17 is fitted on the surface of the pull rod 16. There are eight sets of adjustment holes 8, which are evenly distributed on the surface of the upright rod 2. A ring magnet 15 is fixedly connected to the surface of the insert rod 14. The ring magnet 15 is magnetically connected to the inner bottom surface of the slide groove 13. A sleeve 6 is fixedly connected to one end of the connecting tube 4. The top end of the sleeve rod 3 is threaded into the inside of the sleeve 6. A threaded hole 7 is opened on the surface of the base 1. The bottom end of the upright rod 2 is threaded into the inside of the threaded hole 7. The connecting tube 4 is made of silicone metal. An anti-slip pad 10 is fixedly connected to the surface of the base 1. The anti-slip pad 10 is made of rubber.

[0025] In this embodiment, the spring force of the spring 17 on the inner pull rod 16 of the sleeve 11 pushes the insertion rod 14 into the adjustment hole 8 on the upright rod 2, thereby fixing the sleeve rod 3 and the upright rod 2 together. At the same time, the fixing relationship can be released by pulling the pull rod 16, making the height adjustment of the floor lamp more convenient and time-saving, further improving the efficiency and convenience of the height adjustment of the floor lamp. By setting multiple sets of adjustment holes 8, the height of the lamp head body 5 can be adjusted according to the needs of use. The magnetic attraction between the magnet 15 and the bottom of the slide groove 13 can further improve the stability of the insertion rod 14 inserted into the adjustment hole 8. The threaded connection between the sleeve 6 and the top of the sleeve rod 3, and the threaded connection between the bottom of the upright rod 2 and the base 1, can facilitate the assembly and disassembly of the floor lamp, reduce the space occupied by the floor lamp during transportation, and make the transportation of the floor lamp more convenient. The connecting tube 4, made of silicone metal, allows the lamp head body 5 to rotate arbitrarily, thereby adjusting the lighting angle of the lamp head body 5. The anti-slip pad 10 at the bottom of the base 1 increases the friction between the base 1 and the ground, preventing slippage and displacement, and keeping the floor lamp stable.

[0026] Example 2: As Figure 2 - Figure 3 As shown, a guide rod 9 is fixedly connected to the surface of the upright 2, and a guide groove 12 is opened on the inner surface of the sleeve 3, with the guide rod 9 being engaged inside the guide groove 12.

[0027] In this embodiment, by sliding the guide rod 9 inside the guide groove 12, the sleeve rod 3 is guided and limited when it moves up and down on the surface of the upright rod 2, so as to prevent the sleeve rod 3 from rotating when it moves up and down, so that the adjustment hole 8 finally remains parallel to the insertion rod 14, improving the convenience of inserting the insertion rod 14 into the adjustment hole 8.

[0028] The working principle of this embodiment is as follows: In use, first, turn the bottom knob of the upright 2 inside the threaded hole 7. Then, put the sleeve 3 onto the upright 2. Through the elastic force of the spring 17 on the pull rod 16 inside the sleeve 11, push the insertion rod 14 into the adjustment hole 8 on the upright 2, thus fixing the sleeve 3 to the upright 2. Next, turn the knob of the sleeve 6 at one end of the connecting tube 4 to the top of the sleeve 3. Then, place the floor lamp in the designated position. The anti-slip pad 10 at the bottom of the base 1 increases the friction between the base 1 and the ground, keeping the floor lamp stable. When it is necessary to change the lighting angle of the lamp head body 5, simply rotate the lamp head body 5. The silicone-metal connecting tube 4 allows the lamp head body 5 to bend arbitrarily according to the lighting angle requirements. When it is necessary to adjust the height of the lamp head body 5, hold the sleeve 3 and pull the pull rod 16. The pull rod 16 drives the insertion rod 14 to slide in the groove 13 inside the sleeve 11 and compress the spring 17, then move it up and down. When the lamp head body 5 is adjusted to a suitable height, the sleeve rod 3 is moved up and down a small distance. When the insertion rod 14 is aligned with the adjustment hole 8, the insertion rod 14 will be pushed into the adjustment hole 8 by the elastic force of the spring 17. This process makes the height adjustment of the floor lamp more convenient, time-saving and labor-saving, and further improves the efficiency and convenience of the height adjustment of the floor lamp. When the insertion rod 14 is inserted into the adjustment hole 8, the magnet 15 fixed on the insertion rod 14 will be magnetically attracted to the bottom of the slide groove 13, which further improves the stability of the insertion rod 14 into the adjustment hole 8. When moving on the sleeve rod 3, the guide rod 9 slides in the guide groove 12, which plays a guiding and limiting role when the sleeve rod 3 moves up and down on the surface of the upright rod 2, preventing the sleeve rod 3 from rotating when moving up and down, so that the adjustment hole 8 finally remains parallel to the insertion rod 14, which improves the convenience of inserting the insertion rod 14 into the adjustment hole 8.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
