Description

Technical Field

[0001] This utility model relates to lighting installation technology, and in particular to a convenient and reliable detachable lighting installation device. Background Technology

[0002] When quickly installing lighting fixtures, auxiliary installation tools are often required to detachably assemble the fixtures into specific positions. Current lighting fixture mounting devices generally include components such as a base, a push-fit element, a return spring, and a sliding latch. These components are relatively independent. To assemble these components onto the base, the base must be designed with corresponding assembly positions, such as accommodating cavities for the return spring, positioning protrusions for the return spring, and sliding limit grooves for the sliding latch. These components not only need to be accurately assembled onto the base but also need to connect and cooperate with each other, inevitably leading to the complexity of the auxiliary cooperation structure and assembly structure between product components. Current lighting fixture mounting devices, due to the large number of small components such as individual return springs and individual sliding latches, are very cumbersome to assemble and must rely on manual assembly, making automated assembly difficult and resulting in high production costs. The labor cost for assembly alone is higher than the cost of the components themselves. Furthermore, the quality of this type of lighting fixture installation device, assembled from multiple components, is difficult to guarantee. It frequently experiences jamming, stuck-in, or even components falling apart. For example, during pressing, the sliding latch may jam against the sliding limit groove, preventing it from popping out; or, during pressing, the return spring may deform excessively, detach from the positioning protrusion at the bottom of the push-fit component, and fall off, rendering the entire device malfunction and unusable. In conclusion, this type of lighting fixture installation device, assembled from multiple components, still has many shortcomings and requires corresponding improvements and refinements to reduce its production and assembly costs and enhance the scientific reliability of its overall structure. Utility Model Content

[0003] To address the aforementioned shortcomings, the purpose of this utility model is to provide a detachable lamp installation device. By optimizing the snap-fit ​​and reset structure during the pushing process, it aims to achieve structural integration as much as possible, reduce assembly steps and difficulties, lower production costs, and improve the scientific reliability of its overall structure.

[0004] The technical solution adopted by this utility model is as follows: a detachable lamp installation device, including a base and a push-lock fastener; the push-lock fastener is an integrally formed component, including a push-pressing part, an elastic reset part and an elastic latching part, the elastic reset part is located on the bottom side of the push-pressing part, including an elastic section and a top end, the elastic latching part is located on the side of the push-pressing part, including an elastic arm and a beveled latching part, the beveled latching part is provided with a pressing bevel; the base is provided with a push-receiving cavity, the side of the push-receiving cavity is provided with a snap-fit ​​window adapted to the beveled latching part, the push-lock fastener is located in the push-receiving cavity of the base, wherein the top end of the elastic reset part abuts against the bottom of the push-receiving cavity, and the beveled latching part of the elastic latching part is adapted to the snap-fit ​​window of the push-receiving cavity.

[0005] Furthermore, it also includes a travel limiting component, which includes a fixing part, a limiting rod, and a guide post. The fixing part is located at one end of the limiting rod, and the guide post is located at the other end of the limiting rod. The upper side of the pushing part of the pushing buckle is provided with a travel limiting groove that matches the guide post of the travel limiting component. The base is provided with a limiting component mounting groove that matches the fixing part of the travel limiting component, and one side of the limiting component mounting groove is provided with an avoidance notch corresponding to the limiting rod.

[0006] Furthermore, the limiting rod is an elastically swinging limiting rod, and the stroke limiting groove is an inclined limiting groove; the two ends of the stroke limiting groove are the end points of the pressing stroke, and the bottom of the middle section of the stroke limiting groove is provided with a wave-like concave-convex structure.

[0007] Furthermore, the top end of the elastic reset part of the push-lock fastener is provided with a stop block, and the bottom end of the elastic reset part abuts against the bottom side of the push-accommodating cavity through the bottom surface of the stop block.

[0008] Furthermore, guide protrusions are provided on the left and right sides of the pushing part of the pushing buckle, and guide grooves corresponding to the guide protrusions are provided on the left and right sides of the front section of the pushing receiving cavity of the base.

[0011] Furthermore, the beveled buckle is a wedge-shaped buckle that is thick at the base and thin at the end.

[0012] Furthermore, it also includes a cover plate, which is placed over the pressing and receiving cavity of the base.

[0013] This utility model has the following advantages: By optimizing the snap-fit ​​and reset structure during the pushing process, it achieves structural integration as much as possible; specifically, the pushing part, elastic reset part, and elastic snap-fit ​​part are integrally molded to form an integrated pushing snap-fit ​​component; thus, there is no need to assemble the elastic component and snap-fit ​​component separately, reducing assembly steps and difficulty, and lowering production costs. Moreover, the elastic snap-fit ​​part adopts an elastic arm-type inclined snap-fit, which, in conjunction with the snap-fit ​​window, makes snap-fit ​​convenient and efficient, and is less prone to jamming or failure to pop out. In addition, a stroke limit measure is set, through the cooperation of the stroke limit component and the stroke limit groove, limiting the pushing stroke of the pushing snap-fit ​​component, preventing the pushing snap-fit ​​component from pushing too far, and also preventing the pushing snap-fit ​​component from being ejected from the pushing cavity of the base, improving the scientific reliability of its overall structure.

Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0027] See Figures 1 to 8The detachable lamp mounting device provided in this embodiment includes a base 1 and a push-lock fastener 2. The push-lock fastener 2 is an integrally formed component, including a push-press part 21, an elastic reset part 22, and an elastic latching part 23. The elastic reset part 22 is located on the bottom side of the push-press part 21 and includes an elastic segment 221 and a top end. The elastic latching part 23 is located on the side of the push-press part 21 (it should be noted that it can be provided on only one side or symmetrically on both sides), and includes an elastic arm 231. The base 1 is provided with a pressing bevel 232 and a sloping buckle 232, wherein the sloping buckle 232 is provided with a pressing bevel 233; the base 1 is provided with a pressing receiving cavity 11, wherein the side of the pressing receiving cavity 11 is provided with a snap-fit ​​window 111 adapted to the sloping buckle 232, and the pressing buckle 2 is provided in the pressing receiving cavity 11 of the base 1, wherein the top end of the elastic reset part 22 abuts against the bottom of the pressing receiving cavity 11, and the sloping buckle 232 of the elastic buckle part 23 is adapted to the snap-fit ​​window 111 of the pressing receiving cavity 11.

[0028] Its working principle is roughly as follows: When the pushing part of the push-pressing fastener encounters an external force (usually the installer presses it down with their hand, forming a pushing force), the pushing part overcomes the reset force of the elastic reset part and presses down. The squeezing slope of the inclined fastener cooperates with the side wall of the snap-fit ​​window (because of the existence of the squeezing slope, it can slide relative to the side wall under the action of external force), overcoming the reset force of the elastic arm, thereby causing the inclined fastener to retract to the inside of the snap-fit ​​window, and the position of the inclined fastener no longer corresponds to the snap-fit ​​window (that is, at this time the inclined fastener extends forward a little distance and cannot pop out from the snap-fit ​​window); when the external force encountered by the pushing part is eliminated, the pushing part retracts due to the reset force of the elastic reset part, and the position of the inclined fastener re-corresponds to the snap-fit ​​window (that is, during the retraction of the push-pressing fastener, the inclined fastener will once again correspond to the snap-fit ​​window), and under the action of the reset force of the elastic arm, it pops out to the outside of the snap-fit ​​window, forming a snap-fit ​​effect.

[0029] Specifically, it also includes a travel limiting component 3, which includes a fixing part 31, a limiting rod 32, and a guide post 33. The fixing part 31 is located at one end of the limiting rod 32, and the guide post 33 is located at the other end of the limiting rod 32. The upper side of the pushing part 21 of the pushing buckle 2 is provided with a travel limiting groove 211 that matches the guide post 33 of the travel limiting component 3. The base 1 is provided with a limiting component mounting groove 12 that matches the fixing part 31 of the travel limiting component 3. One side of the limiting component mounting groove 12 is provided with a clearance notch 121 corresponding to the limiting rod 32.

[0030] It should be noted that the travel limit measure is implemented to restrict the pushing stroke of the push-lock component through the cooperation of the travel limit component and the travel limit groove. This prevents the push-lock component from over-pressing and also prevents it from being ejected from the push-receiving cavity of the base, thus improving the overall structural reliability. Furthermore, the cooperation between the guide post and the travel limit groove also provides a guiding effect, making the pressing action more precise and smooth.

[0031] More specifically, the limiting rod 32 is an elastically swinging limiting rod, and the stroke limiting groove 211 is an inclined limiting groove; the two ends of the stroke limiting groove 211 are the end points of the pressing stroke, and the bottom of the middle section of the stroke limiting groove 211 is provided with a wave-like concave-convex structure 212.

[0032] This design aims to provide both guidance and cushioning through the interaction between the guide post and the travel limit groove. The undulating, concave-convex structure creates intermittent reaction force during pressing, resulting in a better feel and allowing the user to intuitively perceive the progress of the press, preventing sudden, excessive pressure and a jarring sensation.

[0033] Specifically, the top end of the elastic reset part 22 of the push-lock fastener 2 is provided with a stop block 222, and the top end of the elastic reset part 22 abuts against the bottom side of the push-accommodating cavity 11 through the bottom surface of the stop block 222.

[0034] This design is intended to increase the force-bearing area of ​​the top of the elastic reset part, avoid stress concentration, and also increase the stability of the elastic reset part, thereby improving its performance and service life.

[0035] Specifically, guide protrusions 213 are respectively provided on the left and right sides of the pushing part 21 of the pushing buckle 2, and guide grooves 112 corresponding to the guide protrusions 213 are respectively provided on the left and right sides of the front section of the pushing receiving cavity 11 of the base 1.

[0036] This design is intended to improve the fit between the push-button fastener and the base, thereby enhancing the accuracy and smoothness of the press.

[0037] Specifically, the pressing slope 233 of the inclined buckle 232 is a "∠" shaped pressing slope; the side of the snap-fit ​​window 111 of the push-accommodating cavity 11 is provided with a matching slope 113 corresponding to the pressing slope 233 of the inclined buckle 232. The two slopes slide parallel to each other, which is stable and reliable and not prone to jamming.

[0038] This design aims to improve the smoothness of the retraction and pop-up between the extrusion slope and the side of the snap-fit ​​window, avoiding any jamming.

[0039] Specifically, the elastic reset part 222 is a folded or wavy elastic reset part.

[0040] This design makes it easier to mold the push-fit fastener in one piece, and the folded or wave-shaped elastic reset part can be better injection molded, simplifying the manufacturing process, simplifying the assembly process, and reducing the manufacturing cost.

[0041] Specifically, the inclined buckle 232 is a wedge-shaped buckle that is thick at the base and thin at the end.

[0042] This design allows the angled latches to pop out or retract more easily from the latching window.

[0043] Specifically, it also includes a cover plate 4, which covers the pressing and receiving cavity 11 of the base 1. This cover plate can seal the internal structure and improve the overall integrity of the detachable lamp installation device.

[0044] This utility model is not limited to the above-described embodiments. Any other lighting installation device obtained by using the same or similar technical features as the above-described embodiments of this utility model is within the protection scope of this utility model.
