Description

Technical Field

[0001] This utility model relates to the field of table clamp devices, specifically to a table clamp for a table lamp. Background Technology

[0002] Clips are common tools used to hold things together. There are many types of clips, with a wide range of uses and different shapes. Desk lamp clips are specifically designed for use on desk lamps to secure them for easy access. Common desk lamp clips typically consist of two plates and a spring, hinged together by a pivot, with the spring's elasticity clamping the object in place.

[0003] The clamping structure of table lamps on the market consists of a clamp with a return spring installed on the base of the table lamp. Since the opening size of the clamp is limited, it cannot clamp the table surface beyond the upper limit of the clamp opening. If the clamp opening is too large, it will result in insufficient clamping force, and the clamp will easily slip, which will cause the table lamp to slip off the table.

[0004] Therefore, it is necessary to invent a table clamp for a desk lamp to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a table clamp for a table lamp that can effectively solve the above-mentioned technical problems.

[0007] The clamping assembly includes: a sliding sleeve, a limiting rod slidably connected to the inner side of the sliding sleeve, a first spring slidably sleeved on the surface of the limiting rod, a clamping plate fixedly installed at the bottom of the limiting rod, an anti-slip plate fixedly installed on the inner side of the clamping plate, a threaded sleeve rotatably connected to the top center of the second limiting groove, a gear fixedly installed on the top of the threaded sleeve, and a threaded rod threadedly connected to the inner side of the threaded sleeve.

[0008] Preferably, a third limiting groove is provided on the upper and lower sides of the left side of the inner cavity of the outer shell, and a first sliding rod is bolted to the inner side of each third limiting groove. A slider is slidably connected to the surface of the first sliding rod, and a second spring is slidably sleeved on the upper part of the surface of the slider.

[0009] Preferably, each slider has a connecting rod hinged to its right side, and the other end of the connecting rod is hinged to the left side of the pull frame.

[0010] Preferably, the upper and lower sides of the left side of the pull frame are bolted with toothed rods, and the lower surface of the toothed rods is slidably connected to the left side of the outer shell.

[0011] Preferably, both the upper and lower ends of the left side of the outer casing are rotatably connected to ratchet rings via bearings, and a handle is bolted to the outer side of the ratchet ring.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figure 1-4 The table clamp for a desk lamp shown includes a housing 1, which serves as an external support and fixing component for the overall table clamp. The lamp post 2 at the top of the housing can be connected to the lamp body. The first limiting groove 3 and the second limiting groove 4 both serve as fixing or installation spaces for the linkage component. The folding plate 5 slides horizontally inside the first limiting groove 3. While being limited, it is fixed to the pull frame 6, so that the pull frame 6 can move while driving the folding plate 5. When the folding plate 5 moves, the rack 7 connected to its right side will also move accordingly.

[0026] The sliding sleeve 81 is fixedly installed on the top of the second limiting groove 4, and the limiting rod 82 on its inner side moves vertically within it. The limiting rod 82 is reset by the spring force of the first spring 83 after the external power is lost. When the rack 7 moves horizontally, it will drive the gear 87 to rotate inside the first limiting groove 3. The gear 87 will then transmit the rotational power to the threaded sleeve 86, causing the threaded sleeve 86 to rotate inside it and gradually move outward. Finally, the vertical movement of the threaded rod 88 pushes the bottom clamping plate 84 to move inward, thereby adjusting the distance between the upper and lower clamping plates 84.

[0027] The third limiting groove 9 mainly serves to connect and support the pull frame 6. Through the first sliding rod 10, the slider 11, and the connecting rod 13 on its inner side, the pull frame 6 is stably fixed to the inner side of the outer shell 1. During the use of the device, by holding the inner side of the pull frame 6 and moving the pull frame 6 towards the third limiting groove 9, the clamping distance between the clamping plates 84 is adjusted. The second spring 12 pushes the slider 11 to move inward towards the sliding rod through its own elastic force, and cooperates with the connecting rod 13 to assist the pull frame 6 in resetting.

[0028] The connecting rod 13 serves to support and connect the pull frame 6.

[0029] The reverse toothed rod 14 can move synchronously with the pull frame 6 on the left side of the outer casing 1 while the pull frame 6 moves horizontally.

[0030] When the reverse gear 14 moves outward, the ratchet ring 15 cannot limit the movement of the reverse gear 14. When the reverse gear 14 moves inward, the ratchet ring 15 meshes with the gear 87 on the reverse gear 14, thus limiting the movement. This process can be unlocked by rotating the ratchet ring 15 with the handle 16.

[0031] The movement angle of the handle 16 is limited by the movement space of the fastener 18 within the placement slot 17.

[0032] The second slide bar 19 limits the movement path of the folding plate 5.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
