Description

Technical Field

[0001] The invention relates to a lamp installation technology, and in particular to a convenient and reliable detachable lamp installation device. Background Art

[0002] When installing lamps quickly, auxiliary installation tools are often needed to detachably assemble the lamps to a specific position. The current lamp installation device generally includes a base, a push piece, a reset spring, a slider-type movable buckle and other parts. These parts are relatively independent. In order to assemble these parts to the base, the base must be designed with corresponding assembly positions, such as a housing cavity for the reset spring, a positioning protrusion for the reset spring, a sliding limit groove for the slider-type movable buckle, etc. These parts must not only be accurately assembled to the base, but also be connected and matched with each other, which inevitably leads to the complexity of the auxiliary matching structure and assembly structure between the product parts. The current lamp installation device is very troublesome to assemble due to the large number of small parts such as a separate reset spring and a separate slider-type movable buckle, and must rely on manual assembly, which makes it difficult to achieve automated assembly, resulting in high production costs. Among them, the labor cost of assembly alone is higher than the cost of the parts themselves. In addition, the quality of this type of lamp installation device assembled from multiple parts is difficult to guarantee, and it is often stuck, stuck, or even the parts fall apart. For example, during the pressing process, the sliding movable buckle and the sliding limit groove become stuck and cannot be ejected; for another example, during the pressing process, the reset spring is over-deformed and detached from the positioning protrusion at the bottom of the push piece, causing it to fly off and fall, and the entire device will become invalid and scrapped. In short, this type of lamp installation device assembled from multiple parts still has many shortcomings, and corresponding improvements and perfections need to be made to reduce its production and assembly costs and improve the scientific reliability of its overall structure. Summary of the invention

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings.

Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0027] See also Figures 1 to 8The detachable lamp installation device provided in this embodiment includes a base 1 and a push buckle 2; the push buckle 2 is an integrally formed component, including a push portion 21, an elastic reset portion 22 and an elastic buckle portion 23, the elastic reset portion 22 is arranged at the bottom side of the push portion 21, including an elastic section 221 and an abutting top end, the elastic buckle portion 23 is arranged at the side of the push portion 21 (it should be noted here that it can be arranged on only one side, or symmetrically on both sides), including an elastic arm 231 and a bevel snap buckle 232, wherein the bevel snap buckle 232 is provided with an extrusion bevel 233; the base 1 is provided with a pushing accommodating chamber 11, and the side of the pushing accommodating chamber 11 is provided with a snap-in window 111 adapted to the bevel snap buckle 232, and the pushing snap buckle 2 is arranged in the pushing accommodating chamber 11 of the base 1, wherein the top end of the elastic reset portion 22 abuts against the bottom of the pushing accommodating chamber 11, and the bevel snap buckle 232 of the elastic snap buckle portion 23 is adapted to the snap-in window 111 of the pushing accommodating chamber 11.

[0028] Its working principle is roughly as follows: when the pushing portion of the pushing buckle encounters an external force (generally, the installer presses it with his hand to form an external pushing force), the pushing portion overcomes the reset elastic force of the elastic reset portion and presses down, the extrusion slope of the inclined buckle cooperates with the side wall of the locking window (because of the existence of the extrusion slope, it can slide relative to the side wall under the action of the external force), overcomes the reset elastic force of the elastic arm, so that the inclined buckle is retracted to the inside of the locking window, and the position of the inclined buckle no longer corresponds to the locking window (that is, the inclined buckle extends forward a little distance at this time and cannot pop out from the locking window); when the external force encountered by the pushing portion is eliminated, the pushing portion retreats due to the reset elastic force of the elastic reset portion, the position of the inclined buckle corresponds to the locking window again (that is, during the retreat of the pushing buckle, the inclined buckle will correspond to the locking window again), and under the action of the reset elastic force of the elastic arm, it pops out to the outside of the locking window to form a locking effect.

[0029] Specifically, it also includes a stroke limiter 3, which includes a fixing portion 31, a limit rod 32 and a guide column 33. The fixing portion 31 is arranged at one end of the limit rod 32, and the guide column 33 is arranged at the other end of the limit rod 32. The upper side surface of the pushing portion 21 of the pushing buckle 2 is provided with a stroke limiter groove 211 adapted to the guide column 33 of the stroke limiter 3; the base 1 is provided with a limiter installation groove 12 adapted to the fixing portion 31 of the stroke limiter 3, and one side of the limiter installation groove 12 is provided with a avoidance notch 121 corresponding to the limit rod 32.

[0030] It should be noted that the reason for setting the travel limit measure is to limit the pushing travel of the push buckle through the cooperation of the travel limit piece and the travel limit groove, to prevent the push buckle from being pushed too far, and to prevent the push buckle from being ejected from the pushing accommodating cavity of the base, thereby improving the scientific reliability of its overall structure. Of course, the cooperation of the guide column and the travel limit groove can also play a certain guiding role, making the pressing action more accurate and smooth.

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

[0032] This design is to make the cooperation between the guide column and the travel limit groove play a guiding role as well as a buffering role. Because of the existence of the undulating concave and convex structure, there will be intermittent reaction force when pressing, which makes the hand feel better and allows the presser to intuitively feel the progress of the pressing stroke from the feedback of this hand feel, avoiding sudden pressing to the bottom and forming an excessive collision feeling.

[0033] Specifically, the top end of the elastic reset portion 22 of the push latch 2 is provided with a resisting block 222 , and the top end of the elastic reset portion 22 resists against the bottom side of the push accommodating cavity 11 through the bottom surface of the resisting block 222 .

[0034] Such a design is to increase the force bearing area of ​​the elastic reset portion at the abutting top end to avoid stress concentration, and also to increase the stability of the elastic reset portion, thereby improving the performance and service life of the elastic reset portion.

[0035] Specifically, guide protrusions 213 are respectively provided on the left and right sides of the pushing portion 21 of the pushing latch 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 accommodating cavity 11 of the base 1.

[0036] This design is to improve the coordination between the push-button fastener and the base, and to improve the accuracy and smoothness of pressing.

[0037] Specifically, the extrusion slope 233 of the slope buckle 232 is a "∠"-shaped extrusion slope; the side of the clamping window 111 of the push accommodating cavity 11 is provided with a matching slope 113 corresponding to the extrusion slope 233 of the slope buckle 232. The two slopes are parallel to each other and slide together stably and reliably, and are not prone to jamming.

[0038] This design is to improve the smoothness of the retraction and pop-up between the extrusion slope and the side of the card-connecting window, and avoid the phenomenon of jamming.

[0039] Specifically, the elastic restoring portion 222 is a folded or wavy elastic restoring portion.

[0040] Such a design is to make it easier to integrally mold the push-on buckle, and the folded or wavy elastic reset portion can be better injection molded, thereby simplifying the production process, simplifying the assembly process, and reducing the production cost.

[0041] Specifically, the inclined surface buckle 232 is a wedge-shaped buckle with a thick root and a thin end.

[0042] This design allows the beveled buckle to pop out or retract from the snap-in window better.

[0043] Specifically, it also includes a cover plate 4, which is covered on the push accommodating cavity 11 of the base 1. The internal structure can be sealed by the cover plate to improve the integrity of the detachable lamp installation device.

[0044] The present invention is not limited to the above-mentioned embodiments. Other lamp installation devices obtained by adopting the same or similar technical features as the above-mentioned embodiments of the present invention are within the protection scope of the present invention.
