Description

Technical Field

[0001] This utility model relates to the field of lighting equipment technology, and in particular to a novel table lamp that is easy to assemble and disassemble. Background Technology

[0002] Desk lamps, as a common local lighting tool, are widely used in homes, offices, and study areas. Traditional desk lamps typically consist of a base, a fixed support rod, and a lamp holder assembly at the top. Once assembled, their structure is basically fixed, and their height and shape are usually unchangeable.

[0003] While this fixed structural design provides stable support and lighting during use, it also has significant drawbacks. When the lamp is not in use or needs to be stored, its fixed form takes up a considerable amount of storage space. Especially in scenarios requiring movement or shipping, such as students moving dormitories or families moving, traditional lamps are cumbersome due to their non-retractable structure, making packaging inconvenient and increasing the likelihood of damage from impacts during transportation.

[0004] While some height-adjustable desk lamps exist in existing technologies, their adjustment mechanisms are often complex or have limited adjustment ranges, failing to fundamentally address the need to transform a desk lamp from a fully functional form into a compact, foldable one. The market urgently needs a solution that is simple in structure and easy to operate, allowing the desk lamp to maintain stability during use while also being easily retractable to minimize its storage and transport volume.

[0005] Therefore, this utility model proposes a new type of table lamp that is easy to assemble and disassemble in order to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a new type of table lamp that is easy to assemble and disassemble, aiming to improve the problems of cumbersome assembly steps for the lampshade and inconvenient storage caused by the inability of the overall structure to be effectively retracted in the existing table lamps.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a novel table lamp that is easy to assemble and disassemble, comprising: a base, and a hollow column fixedly connected to the top of the base; the table lamp further comprises a support column that is slidably fitted inside the hollow column, and a sliding disc, a spring and a semi-circular retaining ball disposed inside the support column, wherein at least one slot is provided on the side wall of the hollow column, and a through hole is correspondingly provided on the side wall of the support column;

[0008] The sliding disk and the spring are movably disposed inside the support column. The semi-circular ball passes through the through hole, and the spring is arranged along the axial direction of the support column. Under normal conditions, the spring applies elastic force to the sliding disk, which in turn drives a portion of the semi-circular ball to extend out of the through hole and engage with the slot of the hollow column to form a lock. When the semi-circular ball is pressed by an external force, this action will cause the sliding disk to compress the spring, thereby allowing the semi-circular ball to retract into the support column and disengage from the slot to release the lock.

[0009] Preferably, a lamp holder is fixedly connected to the top of the support column, and the table lamp also includes a lampshade and a bulb. The lampshade is detachably disposed around the lamp holder, and a pressure plate is disposed at the bottom of the bulb. When the bulb is screwed into the lamp holder, the pressure plate abuts against the lampshade.

[0010] Preferably, the lampshade includes a bracket and a hollow ring, the bracket is fixedly connected to the hollow ring, the hollow ring is sleeved on the outer periphery of the lamp holder, and the pressure plate abuts against the hollow ring.

[0011] Preferably, the pressure plate is an annular boss integrally formed on the bottom of the bulb and surrounding the bulb's screw hole.

[0012] Preferably, the sidewall of the hollow column is provided with a first slot and a second slot at intervals along its length.

[0013] Preferably, the first slot is located above the second slot and is used to lock the support column in the extended position, while the second slot is used to lock the support column in the retracted position.

[0014] Preferably, the sliding disk is provided with an inclined surface for pushing away the semi-circular ball, and the two ends of the spring abut against the inner walls of the sliding disk and the support column, respectively.

[0015] Preferably, the spherical surface of the semi-circular ball faces the outside of the through hole, and the sidewall of the sliding disk abuts against the plane of the semi-circular ball.

[0016] This utility model has the following beneficial effects:

It solves the problem that the lamp cover needs to be installed with independent fasteners, which is complicated and parts are easy to lose. It achieves the effect of simplifying the installation process, improving assembly efficiency and reducing scattered parts.

[0018] 2. This utility model solves the problems of fixed structure, large space occupation, and inconvenience of storage and transportation of existing table lamps by setting a telescopic locking structure composed of spring, sliding plate and semi-circular locking ball between the internal and external supporting column and the hollow column.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figures 1-6The present invention provides an embodiment of a novel table lamp that is easy to assemble and disassemble, comprising a base 1 and a hollow column 2 fixedly connected to the top of the base 1. At least one slot is provided on the side wall of the hollow column 2. The table lamp also includes a support column 4 that is slidably fitted inside the hollow column 2, and a lamp holder 6 is fixedly connected to the top of the support column 4.

[0029] Specifically, the support column 4 is movably equipped with a sliding disk 403 and a spring 401, and a through hole is provided on the side wall of the support column 4. A semi-circular ball 402 is also provided inside the support column 4, and a part of the semi-circular ball 402 can pass through the through hole. The spring 401 is arranged along the axial direction of the support column 4 and is used to apply elastic force to the sliding disk 403. Under the elastic force of the spring 401, the sliding disk 403 can drive the semi-circular ball 402 to extend out of the through hole.

[0030] In the locked state, the spring 401 pushes the sliding disk 403, which in turn pushes the semi-circular locking ball 402, causing the spherical part of the semi-circular locking ball 402 to extend out of the through hole of the support column 4 and be locked into the slot on the side wall of the hollow column 2, thereby locking the position of the support column 4 relative to the hollow column 2.

[0031] When adjustment or storage is required, an external force is applied to the semi-circular locking ball 402, causing it to move into the support column 4. The movement of the semi-circular locking ball 402 pushes the sliding disk 403 to compress the spring 401 until the spherical part of the semi-circular locking ball 402 is completely retracted into the support column 4, disengaging from the slot. At this time, the support column 4 can slide freely along the hollow column 2. When the support column 4 slides to the corresponding position of the next slot, the external force is released, the compressed spring 401 recovers its deformation, and pushes the sliding disk 403 and the semi-circular locking ball 402 again, causing the semi-circular locking ball 402 to engage in the new slot, completing the new position locking.

[0032] The lampshade 3 includes a bracket 301 and a hollow ring 302. The bracket 301 and the hollow ring 302 are fixedly connected. During assembly, the hollow ring 302 is fitted onto the outer periphery of the lamp holder 6. The bottom of the bulb 5 is provided with a pressure plate 501, which is an annular boss integrally formed on the bottom of the bulb 5 and surrounding the bulb screw hole.

[0033] In the assembled state, when the bulb 5 is screwed into the lamp holder 6 by means of a rotating connection, the pressure plate 501 will move closer to the lamp holder 6 in sync with the screwing action of the bulb 5, and finally abut against the upper surface of the hollow ring 302. As the bulb 5 is tightened, the pressure plate 501 generates continuous axial pressure on the hollow ring 302, thereby firmly clamping and fixing the entire lamp cover 3 assembly composed of the bracket 301 and the hollow ring 302 onto the lamp holder 6, eliminating the need for additional fasteners and ensuring the convenience of the installation process;

[0034] To ensure the stable locking of the desk lamp in both extended and retracted states, the side wall of the hollow column 2 is provided with a first slot 201 and a second slot 202 spaced apart along its length. The first slot 201 is located above the second slot 202 and is used to lock the desk lamp in the extended position when the support column 4 is fully extended, with the semi-circular locking ball 402 engaging with the first slot 201. The second slot 202 is used to lock the desk lamp in the retracted position when the support column 4 is fully retracted, with the semi-circular locking ball 402 engaging with the second slot 202.

[0035] To optimize the retraction action of the semi-circular ball 402 and ensure effective force transmission, the sliding disk 403 is provided with an inclined surface for pushing the semi-circular ball 402 away. The two ends of the spring 401 abut against the inner walls of the sliding disk 403 and the support column 4, respectively. The spherical surface of the semi-circular ball 402 faces the outside of the through hole so as to smoothly engage and disengage with the first slot 201 or the second slot 202. At the same time, the plane of the semi-circular ball 402 abuts against the side wall of the sliding disk 403. When the semi-circular ball 402 is pressed, the inner end of the semi-circular ball 402 slides along the inclined surface of the sliding disk 403, thereby efficiently converting the radial pressing force into an axial thrust on the sliding disk 403, and thus compressing the spring 401.

[0036] Working principle: When adjusting the height of the desk lamp or storing the desk lamp, by pressing the semi-circular retaining ball 402 exposed outside the support column 4, the inner end of the semi-circular retaining ball 402 will slide along the inclined surface of the sliding plate 403, thereby pushing the sliding plate 403 to move axially inside the support column 4 and compressing the spring 401. When the spring 401 is fully compressed, the spherical part of the semi-circular retaining ball 402 will completely retract into the support column 4, disengaging from the first slot 201 on the hollow column 2. At this time, the support column 4 is unlocked and can slide freely downward under the limit of the hollow column 2. When the support column 4 slides to the storage position, the semi-circular retaining ball 402 is aligned with the second slot 202. After releasing the pressing force, the compressed spring 401 releases its elasticity and pushes the sliding plate 403 to reset. The sliding plate 403 then pushes the semi-circular retaining ball 402 out again and locks it into the second slot 202, thus locking the storage state.

[0037] When assembling the lampshade, the lampshade 3 assembly, consisting of bracket 301 and hollow ring 302, is first fitted onto the outer periphery of the lamp holder 6. Then, the bulb 5 is aligned with the screw hole of the lamp holder 6 and screwed in. During the screwing of the bulb 5, the pressure plate 501 located at the bottom of the bulb 5 moves toward the lamp holder 6 and eventually contacts the upper surface of the hollow ring 302. When the bulb 5 is tightened, the pressure plate 501 will generate continuous axial pressure on the hollow ring 302. This pressure, through the hollow ring 302 and bracket 301, firmly presses the entire lampshade 3 onto the lamp holder 6, thereby completing the fixation of the lampshade.
