Description

Technical Field

[0001] This utility model belongs to the field of lighting installation technology, specifically, it relates to an anti-detachment lighting installation structure. Background Technology

[0002] Currently, installing light fixtures (such as ceiling lights) on ceilings or walls usually requires the assistance of auxiliary installation structures. For example... Figures 1 to 3 As shown, a common installation structure in the prior art is a hanging plate type, which includes an existing I-frame 1 and a matching existing movable hanging plate 2. The existing I-frame 1 is fixed to the ceiling or wall by bolts, and the existing movable hanging plate 2 is connected to or integrated with the lamp body. The mounting surface of the existing movable hanging plate 2 (i.e., the side facing the ceiling or wall) has symmetrically arranged fixed cylindrical clips 3 on both sides, while the I-frame 1 has corresponding strip-shaped slots 4 on both sides. The bottom edge of the slots 4 is designed with a toothed structure. During installation, the existing movable hanging plate 2 is pushed along the slots 4 to engage the cylindrical clips 3, thus completing the installation.

[0003] However, the above structure has the following potential problems in actual use: First, because such lamps are usually quite heavy, and the slot 4 has a U-shaped opening, it is prone to deformation or even opening after bearing the weight of the lamp for a long time, causing the lamp to fall off and posing a safety hazard. Second, during installation, operators cannot directly observe the actual alignment of the locking parts. Whether it is installed properly can only rely on personal experience and feel, making it difficult to accurately judge whether the cylindrical clip 3 is fully inserted into the slot 4. If it is not properly installed (for example, the cylindrical clip 3 is only partially inserted, or is blocked by the toothed structure at the lower edge of the slot 4), after long-term use, the slot 4 is prone to being stretched and deformed due to excessive local force, which also increases the risk of the lamp falling off. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-detachment lamp installation structure to solve the technical problems existing in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An anti-detachment lighting fixture installation structure includes a frame for fixed installation on a ceiling wall and a movable mounting plate for connecting the lighting fixture. Connecting strips are fixedly provided at the left and right ends of the frame, and each connecting strip has upwardly bent elastic clips at both its front and rear ends. Fasteners corresponding to the positions of the elastic clips are fixedly provided on both sides of the mounting surface of the movable mounting plate. Each elastic clip includes an L-shaped plate whose upper end connects to the end of the connecting strip, an arc-shaped portion extending outwards and bent from the lower end of the L-shaped plate, and a straight plate extending downwards from the end of the arc-shaped portion. In the assembled state, the straight plate and the arc-shaped portion pass through the fasteners, and the lower part of the L-shaped plate abuts against the upper part of the fasteners.

[0007] Preferably, a limiting protrusion is vertically provided on the lower part of the L-shaped plate, and a locking hole that mates with the limiting protrusion is provided on the lower end face of the fastener. In the assembled state, the limiting protrusion is engaged in the locking hole.

[0008] Preferably, the bow-shaped portion is arc-shaped, and the height of the apex of the arc is higher than the upper surface of the fastener.

[0009] Preferably, the free end of the straight plate portion is lower than the lower end face of the fastener in its natural state.

[0010] Preferably, the connecting strip is welded to the I-beam frame or is an integral structure.

[0011] Preferably, the fastener is in the form of an inverted U-shape or L-shape.

[0012] Preferably, the elastic clip and the connecting strip are integrally formed.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) The present invention is provided with a connecting strip, elastic clip and fastener connection structure. During assembly, the straight plate is first put into the fastener. Continue to push the movable hanging plate. The bow-shaped part will be under force and slowly deform downward until the top of the arc surface. Continue to push the movable hanging plate. The bow-shaped part will return to its original shape due to the elastic force until it forms a fit with the upper part of the fastener through the L-shaped plate. On the one hand, it effectively avoids the technical problem that the traditional U-shaped slot is prone to deformation or even opening after bearing the weight of the lamp for a long time, which leads to the lamp falling off. On the other hand, based on the structural design of the elastic clip, only after it is fully installed can an effective fit be formed without loosening, avoiding the situation of not being assembled in place.

[0015] (2) The present invention provides a limiting protrusion on the L-shaped plate and a card hole on the fastener, thereby forming a double insurance mechanism. This structure not only makes the connection very stable and can effectively bear the weight of the lamp, but also effectively prevents accidental loosening caused by vibration or long-term load, thus ensuring high safety.

[0016] (3) The main components of this utility model can be integrally formed by stamping, bending and other processes or simply welded. The structure is simple, the manufacturing cost is low, and it is suitable for mass production. Attached Figure Description

[0025] To enable those skilled in the art to have a clearer understanding of this utility model, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described below are merely illustrative of this utility model and facilitate understanding. The technical solutions provided by this utility model are not limited to those provided in the following embodiments, nor should they limit the scope of protection of this utility model.

[0026] Example

[0027] like Figures 4-6As shown, this embodiment provides an anti-detachment lamp installation structure, which mainly consists of a fixed part and a movable part. The fixed part is a frame 5, which is fixed to a predetermined position on the ceiling wall by screws and other fasteners. The left and right ends of the frame 5 are fixed with connecting strips 7 by welding or integral molding. Each connecting strip 7 has an upwardly bent elastic clip 8 at both ends, for a total of four elastic clips, one at each end of the left and right sides. In this embodiment, the elastic clips 8 and the connecting strips 7 are preferably integrally molded and made of metal sheet with good elasticity by stamping and bending.

[0028] In this embodiment, the elastic clip 8 specifically includes an L-shaped plate portion 81, an arc-shaped portion 82, and a straight plate portion 83. The upper end of the L-shaped plate portion 81 is connected to the end of the connecting strip portion 7. The arc-shaped portion 82 extends outward from the lower end of the L-shaped plate portion 81 and bends to form an arc shape. The straight plate portion 83 extends vertically downward from the end of the arc-shaped portion 82. In a further embodiment, a limiting protrusion 84 is vertically stamped on the lower plate of the L-shaped plate portion 81.

[0029] The movable part is the movable mounting plate 6, which is fixedly connected to the lamp body by screws, or is integrated with the lamp body. On both sides of the mounting surface of the movable mounting plate 6 facing the ceiling, there are fixed fasteners 9 that correspond one-to-one with the positions of the four elastic clips 8 on the I-beam frame 5. The fasteners 9 are inverted U-shaped, and their lower end faces have a locking hole 91 that matches the shape and size of the aforementioned limiting protrusion 84.

[0030] The relationship between each component in the elastic clip 8 and the fastener is as follows: the height of the apex of the arc of the bow-shaped part 83 is higher than the upper end face of the fastener 9, while the free end of the straight plate part 83 ( Figures 5-6 The right end shown is below the lower end face of the card firmware 9 in its natural state.

[0031] During installation, first fix the I-frame 5 to the ceiling; then, lift the movable mounting plate 6 along with the light fixture, so that the openings of the four fasteners 9 are aligned with the four elastic fasteners 8 respectively; push the movable mounting plate 6 in the direction of the elastic fasteners 8, so that the straight plate part 83 and the bow-shaped part 82 of the elastic fastener 8 first enter the U-shaped space of the fastener 9; continue to push the movable mounting plate 6, and the arc-shaped surface of the bow-shaped part 82 will contact and be stressed with the upper edge (end edge) of the fastener 9, forcing the elastic fastener 8 to produce a slight elastic deformation as a whole.

[0032] When not properly installed (not properly assembled), the end face of the fastener will contact the bow-shaped part. If the movable mounting plate is not pushed further at this time, an effective locking engagement cannot be formed, and the lower lamp body will immediately fall under the influence of gravity. In other words, the lamp body cannot be held. This can prevent the risk that the lamp body will fall down and injure people due to improper installation by the installer when using the existing mounting plate structure.

[0033] Continue pushing the movable mounting plate. When the limiting protrusion 84 contacts and passes the lower edge of the fastener 9, you will clearly feel a process of overcoming resistance. Once the limiting protrusion 84 is fully slid into the locking hole 91, the elastic locking piece 8 instantly rebounds, making a "click" sound. At the same time, you will feel a clear sense of completion. At this point, the installation is complete. Figure 6 As shown.

[0034] When assembled, the lower part of the L-shaped plate 81 is reliably abutted against the upper part of the fastener 9, bearing the main weight; the engagement of the limiting protrusion 84 and the locking hole 91 provides a reliable anti-disengagement locking function; the apex of the bow-shaped part 82 is higher than the upper surface of the fastener 9, and the free end of the straight plate 83 is lower than the lower surface of the fastener 9, ensuring sufficient stroke and stability for engagement.

[0035] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
