Description

Technical Field

[0001] The utility model relates to the technical field of lighting tools, in particular to a bent-arm type table clamp fixing table lamp. Background Art

[0002] A bent-arm desk lamp is a lighting device with a flexible design. It usually has one or more freely bendable lamp arms, allowing users to adjust the lighting angle and direction as needed. However, although existing desk lamps can adjust the lighting angle and direction, the lamp head often cannot rotate 360°, and is still not convenient to use.

[0003] Based on the above problems, the existing patent with announcement number CN206449479U discloses a bent-arm table clamp to fix the desk lamp, which uses multiple connecting rod linkage mechanisms to achieve a large range of movement of the lampshade of the desk lamp, and the entire lampshade can rotate 360°, thereby expanding the lighting range and making it more convenient for users to use the desk lamp.

[0004] However, when implementing the above-mentioned bent-arm desk clamp to fix the desk lamp, it was found that there were at least the following problems: after a long period of use, the light bulb generally needs to be replaced, and the light bulbs available on the market are generally larger in size (i.e., ordinary household light bulbs). This also results in the light bulb partially exposing the lampshade after the bulb is replaced. At this time, the light emitted by the bulb will directly hit the eyes, affecting the user's office and reading. The common solution is usually to customize or purchase a light bulb that is compatible with the desk lamp, but the purchase is more troublesome or takes a long time, and the desk lamp cannot be used immediately.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example: See Figures 1 to 5 According to an embodiment of the utility model, a technical solution is provided: a bent-arm desk clamp fixed desk lamp, comprising: a desk clamp 1, a multi-stage lamp arm 2, a desk lamp body 3 and a light shielding component 4, wherein the desk clamp 1 can be clamped on the edge of a desktop; one end of the multi-stage lamp arm 2 is embedded in the desk clamp 1 and is rotatably connected to the desk clamp 1; the desk lamp body 3 comprises a light bulb 301 and a lampshade 302, wherein the lampshade 302 is mounted on the free end of the multi-stage lamp arm 2, the light bulb 301 is mounted in the lampshade 302, and the lampshade 302 is a funnel The light-shielding component 4 comprises a ring track 401, a light-shielding cloth 402 and a plurality of supporting frames 403. The ring track 401 is fixed to the outer wall of the lampshade 302. The plurality of supporting frames 403 are all embedded in the ring track 401 and are slidably connected to the ring track 401. The free end of the supporting frame 403 protrudes from the flared end of the lampshade 302. The light-shielding cloth 402 is wrapped around the plurality of supporting frames 403.

[0027] The bent-arm desk clamp 1 of the above structure is used to fix the desk lamp. When the replaced bulb 301 does not match and partially protrudes from the flared end of the lampshade 302, the light emitted by the bulb 301 will directly hit the user's eyes. In order to avoid glare affecting the user's reading and writing, the multiple supporting frames 403 can be driven to slide in the circular track 401, so that the light-shielding cloth 402 blocks the light directed to the user's eyes, reducing the impact of the mismatched bulb 301 on the user, so that the desk lamp can still be used normally after the mismatched bulb 301 is replaced.

[0028] In this embodiment, the free end of the support frame 403 is the place most likely to come into contact with the user. Although it is wrapped with a light-blocking cloth 402, it poses certain safety hazards. For this reason, the free end of the support frame 403 is set to be an arc shape so that the free end of the support frame 403 has no sharp angles, thereby increasing safety to a certain extent.

[0029] In this embodiment, the traditional switch is generally set on the table clamp 1, but the table clamp 1 is generally located at the upper left of the desktop. At this time, there is still a little distance between the user and the upper left of the desktop, so that the user may need to lean over and reach out to touch the switch when turning on or off the desk lamp. In order to facilitate the user to turn on and off, a control switch 5 is installed at the narrow end of the lampshade 302, that is, the top of the lampshade 302. When the user uses it, the distance from the lampshade 302 to the user is generally closer to the distance from the table clamp 1 to the user. The user only needs to reach out without leaning over, which makes it more convenient for the user.

[0030] In this embodiment, the table clamp 1 is mainly fixed on the edge of the table top. In order to increase the stability of the table clamp 1 in clamping the table top, the table clamp 1 includes an upper seat 101, a lower base 102, an arc rod 103 and a nut 104. The arc rod 103 is fixed on one side of the upper seat 101, the lower base 102 is slidably connected to the arc rod 103, and the nut 104 is threadedly connected to the arc rod 103. By twisting the nut 104, the lower base 102 is driven to move toward the upper seat 101, so that the upper seat 101 and the lower base 102 clamp and fix the table top.

[0031] In this embodiment, in order to increase the flexibility of the multi-stage lamp arm 2 , trapezoidal fine-tuning members 6 are installed at the hinges of the multi-stage lamp arm 2 .

[0032] In this embodiment, the desk lamp body 3 often needs to be illuminated for a long time for users to study and illuminate, and its working time is generally 2-4 hours. Although the bulb 301 will not generate heat, the connection of the bulb 301 is prone to generate heat. For this reason, a heat dissipation hole 7 is opened on the outer wall and top of the narrow end of the lampshade 302 for heat dissipation.

[0033] Working principle:

[0034] S1: During the installation process, the upper seat 101 is firstly pressed against the desktop, and the user holds the lower base 102 against the bottom of the desktop, and then twists the nut 104 so that the nut 104 threadedly connected with the arc rod 103 limits the lower base 102, and then twists the nut 104 so that the nut 104 drives the lower base 102 to move upward, so that the lower base 102 and the upper seat 101 are tightly clamped on the desktop, and then the multi-stage lamp arm 2 can be adjusted, so that the multi-stage lamp arm 2 drives the table lamp body 3 to illuminate the desktop;

[0035] S2: During the use of the light-blocking component 4, when the replaced bulb 301 partially protrudes from the lampshade 302, the multiple support frames 403 can be slid in the circular track 401, so that the light-blocking cloth 402 on the multiple support frames 403 blocks the light emitted by the bulb 301. When it is not needed, even if the light-blocking cloth 402 is facing the user, it will not block the light, and the lampshade 302 has a light-blocking function. Secondly, since there are multiple support frames 403, when two adjacent support frames 403 are against each other, the light-blocking cloth 402 will fold or bulge, thereby reducing the light-blocking range. When the two adjacent support frames 403 are fully unfolded, the light-blocking cloth 402 is stretched open by the two support frames 403, thereby increasing the light-blocking range.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
