Abstract
Description
Technical Field
[0001] This utility model relates to the field of lighting technology, specifically to a bending and adjustable lighting fixture. Background Technology
[0002] Lighting fixtures, also known as lighting equipment, are devices that can fix and protect light sources, adjust the distribution of light, and emit lighting that meets the needs. They are not only carriers of light sources (such as light bulbs), but also important home and commercial products that integrate functionality, aesthetics, and safety.
[0003] Existing lighting fixtures such as desk lamps and work lamps mostly use a hinged structure for their lamp arms, which adjust the lighting angle by rotating multiple joints. However, they can usually only bend in a single plane, making it difficult to achieve positioning in three-dimensional space. Furthermore, after the joints are locked, they are prone to loosening after long-term use or under slight external force, causing the lamp head to droop and making it impossible to maintain the set lighting angle. Therefore, a bending adjustment lamp fixture is proposed. Utility Model Content
[0004] The purpose of this utility model is to provide a bending and adjustable lamp to solve at least one of the technical problems existing in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A bendable adjustable light fixture, comprising:
[0007] The base and the lamp head are provided with a bending adjustment component and a support component on the outer side of the base. The bending adjustment component is used to adjust the lighting angle of the lamp head, and the support component is used to improve the stability of the lamp head.
[0008] The bending adjustment assembly includes a support core, a joint segment, a ball socket, and a ball head;
[0009] The support core is disposed at the joint of the base, the joint segment is sleeved on the outside of the support core, the ball head is disposed at the end of one of the joint segments, the ball socket is disposed at the end of an adjacent joint segment, and the ball socket is adapted to the ball head.
[0010] Preferably, adjacent articular segments are connected by the ball socket and ball head, enabling multi-degree-of-freedom relative deflection between adjacent articular segments.
[0011] Preferably, the support core is used to bend and deform under external force, and to maintain the deformed shape after the external force is removed.
[0012] Preferably, there is a gap between the inner wall of the joint segment and the outer wall of the support core, and the support core is a wire rope structure.
[0013] Preferably, the lamp head and the bending adjustment component are connected by an adapter, and the bottom of the base is provided with an anti-slip pad.
[0014] Preferably, the support assembly includes a slide, a slide block, a spring, a connecting rod, and a rotating seat;
[0015] The slide groove is formed on the inner side of the base, the slide block is slidably connected to the inner side of the slide groove, the spring is fixedly installed on the inner side of the slide groove, the connecting rod is rotatably connected to one side of the slide block, and the rotating seat is rotatably connected to the surface of the support core in the direction close to the lamp head.
[0016] Preferably, the spring is fixedly connected to the end of the slide block, and the spring in the extended state is used to assist the slide block in sliding.
[0017] Preferably, the connecting rod is rotatably connected to one end of the rotating seat, and both the rotating seat and the connecting rod are in an inclined state.
[0018] Preferably, the connecting rod and the rotating seat can automatically adjust their tilt angle as the support core bends.
[0019] Compared with the prior art, the beneficial effects of this utility model are:
[0020] 1. By setting up a bending adjustment component, an external force is applied to the support core, and adjacent joint segments are connected by a ball joint and a ball socket to form a universal ball joint. Therefore, the entire lamp arm can be bent in any direction in three-dimensional space to achieve positioning in three-dimensional space and lock all joint segments. The entire bending adjustment component changes from a flexible structure that can move flexibly to a rigid and fixed structure, and finally firmly maintains the set lighting angle.
[0021] 2. By setting up a support component, the bending adjustment component does not need to provide a huge locking force to counteract the torque of the entire lamp arm. It only needs to provide enough friction to maintain the joint shape and balance the remaining small part of the torque. Moreover, since the spring force is continuous, even if the friction between the ball socket and the ball head is slightly reduced due to vibration or wear, the support component can still provide reliable compensatory support, effectively preventing the lamp head from sagging.

[0031] Please see Figures 1-4 The present invention provides an embodiment of a bendable adjustable lamp:
[0032] A bendable adjustable light fixture, comprising:
[0033] The base 1 and the lamp head 2 are provided. The outer side of the base 1 is provided with a bending adjustment component 3 and a support component 4. The bending adjustment component 3 is used to adjust the lighting angle of the lamp head 2, and the support component 4 is used to improve the stability of the lamp head 2.
[0034] The bending adjustment assembly 3 includes a support core 301, a joint segment 302, a ball socket 303, and a ball head 304;
[0035] The support core 301 is disposed at the joint of the base 1, the joint segment 302 is sleeved on the outside of the support core 301, the ball head 304 is disposed at the end of one joint segment 302, and the ball socket 303 is disposed at the end of an adjacent joint segment 302, and the ball socket 303 is adapted to the ball head 304.
[0036] Adjacent joint segments 302 are connected to ball heads 304 via ball sockets 303, enabling multi-degree-of-freedom relative deflection between adjacent joint segments 302. The above structural design allows adjacent joint segments 302 to form a universal ball joint connection via ball heads 304 and ball sockets 303. Therefore, the entire lamp arm can be bent in any direction in three-dimensional space, achieving positioning in three-dimensional space.
[0037] The support core 301 is used to bend and deform under external force and maintain the deformed shape after the external force is removed. The above structural design allows the user to apply external force to the lamp head 2 or the support core 301 by hand.
[0038] In one preferred embodiment, there is a gap between the inner wall of the joint segment 302 and the outer wall of the support core 301, and the support core 301 is a steel wire rope structure. The above structural design allows the support core 301 (made of plastically deformable steel wire rope) sleeved inside to bend accordingly. Its material properties enable it to initially maintain its deformed shape after the external force is removed, providing a pre-support effect for the lamp.
[0039] In one preferred embodiment, the lamp head 2 is connected to the bending adjustment component 3 via an adapter, and the bottom of the base 1 is provided with an anti-slip pad. The above structural design allows the joint segment 302 to be manually locked, forcing all the contact surfaces of the ball head 304 and the ball socket 303 to fit tightly together, generating a huge static friction force. This friction force is sufficient to overcome the torque brought about by the weight of the lamp head 2, thereby locking the joint segment 302.
[0040] In one preferred embodiment, the support assembly 4 includes a slide 401, a slide block 402, a spring 403, a connecting rod 404, and a rotating seat 405;
[0041] The slide groove 401 is formed on the inner side of the base 1, the slide block 402 is slidably connected to the inner side of the slide groove 401, the spring 403 is fixedly installed on the inner side of the slide groove 401, the connecting rod 404 is rotatably connected to one side of the slide block 402, and the rotating seat 405 is rotatably connected to the surface of the support core 301 in the direction close to the lamp head 2. The above structural design allows the joint segment 302 to not provide a huge locking force to resist the torque of the entire lamp arm alone with the help of the support component 4, but only to provide enough friction to maintain the joint shape and balance the remaining small part of the torque.
[0042] In one preferred embodiment, the spring 403 is fixedly connected to the end of the slide 402, and the spring 403 in the extended state is used to assist the slide 402 in sliding. The above structural design causes the connecting rod 404 to drag the slide 402 backward in the slide groove 401. This action compresses the spring 403, and the compressed spring 403 will generate a reverse elastic restoring force. This force is transmitted to the bending adjustment component 3 through the slide 402, the connecting rod 404 and the rotating seat 405, forming an upward supporting force.
[0043] In one preferred embodiment, the connecting rod 404 is rotatably connected to one end of the rotating seat 405, and both the rotating seat 405 and the connecting rod 404 are in an inclined state. The above structural design makes it so that when the lamp arm is bent, the rotating seat 405 fixed on the support core 301 moves downward, and the rotating seat 405 pulls the connecting rod 404 downward.
[0044] In one preferred embodiment, the connecting rod 404 and the rotating seat 405 can adjust their tilt angles automatically as the support core 301 bends. The above structural design allows the slide 402, connecting rod 404 and rotating seat 405 to ultimately transmit to the bending adjustment assembly 3, forming an upward supporting force. This supporting force generates a supporting moment that is opposite in direction to the overturning moment generated by the weight of the lamp head 2.
[0045] The working principle of this utility model is as follows: First, the user applies external force to the lamp head 2 or the support core 301 by hand. Since the adjacent joint segments 302 are connected by a universal ball joint 304 and a ball socket 303, the entire lamp arm can be bent in any direction in three-dimensional space to achieve positioning in three-dimensional space. The support core 301 (made of malleable steel wire rope) is bent accordingly. Its material properties allow it to initially maintain its deformed shape after the external force is removed, providing a pre-support effect for the lamp and facilitating the user's rough positioning. When the lamp arm is bent to the required angle, the joint segment 302 is manually locked, forcing all the contact surfaces of the ball heads 304 and ball sockets 303 to fit tightly together, generating a huge static friction force. This friction force is sufficient to overcome the torque brought by the weight of the lamp head 2, thereby locking the joint segment 302 and changing the entire bending adjustment component 3 from a flexible structure that can move flexibly to a rigid and fixed structure, ultimately firmly maintaining the set lighting angle.
[0046] When the bending adjustment component 3 is in an upright or near-upright state, the center of gravity projection of the lamp head 2 is close to the base 1, and the overturning moment generated by its own weight is minimal. At this time, the spring 403 in the support component 4 is in a naturally extended or slightly compressed state, and the force applied to the rotating seat 405 through the connecting rod 404 is also small. The position of the slide 402 in the slide groove 401 is closer to the lamp head 2. At this time, the support component 4 mainly plays an auxiliary stabilizing role. When the user bends the lamp arm downward and outward, the center of gravity of the lamp head 2 moves forward continuously, and the overturning moment generated by its own weight increases significantly. The traditional structure cannot maintain the joint locking friction for a long time and is prone to sagging. Therefore, when the lamp arm is bent, the rotating seat 405 fixed on the support core 301... As it moves downwards, the rotating seat 405 pulls down the connecting rod 404, which in turn drags the slide 402 backwards (away from the lamp head 2) within the slide groove 401. This action compresses the spring 403, which generates a reverse elastic restoring force. This force is transmitted through the slide 402, connecting rod 404, and rotating seat 405 to the bending adjustment assembly 3, forming an upward supporting force. This supporting force generates a supporting torque opposite to the overturning torque generated by the weight of the lamp head 2. This supporting torque effectively offsets most of the additional load generated by the weight of the lamp head 2, effectively reducing the locking pressure of each universal ball joint in the bending adjustment assembly 3.

It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model.
