[0003] The spring buckle is the core connecting piece for fixing the down lamp and the mounting hole, and at present, the assembly of the down lamp and the spring buckle in the industry generally adopts the screw fastening or rivet riveting mode. This type of fixing mode, on the one hand, needs to use special tools such as screwdrivers and rivet guns in the assembly process, and the operation steps are complicated. The screws or rivets need to be aligned one by one, which not only consumes time and effort, but also easily causes the buckle to deviate or the lamp housing to be damaged due to improper operation, thereby seriously restricting the assembly efficiency of production and on-site installation. On the other hand, the use of additional connecting pieces such as screws and rivets increases the procurement cost of parts, and the investment in special tools and the extension of manual operation time further increases the comprehensive cost of production and installation. SUMMARY

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0006] A spring buckle structure of down lamp, comprising two torsion spring rings arranged at intervals, a U-shaped compression part connected to the inner ends of the two torsion spring rings opposite to each other, and an elastic mounting part provided at the outer ends of the two torsion spring rings. The elastic mounting part is used for mounting into the mounting slot of the down lamp. The elastic mounting part comprises an integrally bent mounting plug, a limiting protruding part and a limiting inclined rod. One end of the mounting plug is connected to the torsion spring ring. The limiting protruding part is bent outward from the outer side of the mounting plug and used for abutting against the lower end of the mounting slot. The limiting inclined rod extends inward and upward at an inclination and abuts against the limiting block in the mounting slot.

[0007] In some embodiments, the mounting plug extends vertically downward.

[0013] In some embodiments, the stop block is provided in the installation clamping groove and located at the lower end of the limiting block, and the stop block is located between the two limiting inclined rods.

[0014] Compared with the prior art, the utility model has the beneficial effects that:

[0015] 1. The elastic mounting part of the structure adopts an integral bending forming design, and can be fixed by directly inserting the installation plug rod into the installation clamping groove of the down lamp, without the need for additional connecting members such as screws and rivets, and without the need for special tools. During assembly, the inclined guide structure of the limiting inclined rod can guide the installation plug rod to be quickly and accurately inserted into the clamping groove, and the elastic pre-tightening force of the U-shaped pressing part is used to realize the quick clamping and fixing of the buckle and the down lamp, thereby greatly simplifying the assembly steps, shortening the operation time, significantly improving the assembly efficiency of production and on-site installation, reducing the labor input, and reducing the labor cost.

[0024] The following specific implementation provides for the implementation of the utility model various different embodiments or examples. Of course, these are only examples and are not intended to be limiting. In addition, repeated labels may be used in different embodiments, such as repeated numbers and / or letters. These repetitions are for the simple and clear description of the utility model, and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0025] As Figures 1-6 The utility model discloses a spring buckle structure and a down lamp, the down lamp includes down lamp shell 51, spring buckle mounting seat 52 and spring buckle structure, spring buckle mounting seat 52 is provided with two, respectively symmetrically set up in the outside of down lamp shell 51, and each spring buckle mounting seat 52 is provided with the installation clamping groove 10 that passes through up and down, and the upper end position in the installation clamping groove 10 is provided with the limit block 11.

[0026] The utility model discloses a spring buckle structure and a down lamp, the down lamp includes down lamp shell 51, spring buckle mounting seat 52 and spring buckle structure, spring buckle mounting seat 52 is provided with two, respectively symmetrically set up in the outside of down lamp shell 51, and each spring buckle mounting seat 52 is provided with the installation clamping groove 10 that passes through up and down, and the upper end position in the installation clamping groove 10 is provided with the limit block 11.

[0027] When the spring buckle structure is assembled, the operator holds the U-shaped pressing part 2 of the buckle, aligns the installation insertion rod 4 of the elastic mounting part 3 on both sides with the upper end entrance of the down lamp mounting clamping groove 10; at this time, the limiting protruding part 5 (bent outwardly protruding from the installation insertion rod) on the elastic mounting part 3 is in contact with the inner wall of the mounting clamping groove 10 on both sides and is extruded, and the inclined surface of the limiting inclined rod 6 is in contact with the limiting block 11 in the mounting clamping groove 10 and is extruded; under the double extrusion effect, the limiting protruding part 5 and the limiting inclined rod 6 are synchronously elastically deformed inwardly, guiding the installation insertion rod 4 to smoothly advance into the inside of the mounting clamping groove 10.

[0028] When the installation insertion rod 4 is completely inserted into the preset position, the extrusion external force applied to the limiting protruding part 5 and the limiting inclined rod 6 disappears, and the elastic deformation of the two is synchronously recovered. At this time, the limiting protruding part 5 tightly abuts against the lower end surface of the mounting clamping groove 10 after springback, forming axial and radial limiting, preventing the buckle from being separated upward and displaced; the upper end of the limiting inclined rod 6 abuts against the lower end surface of the limiting block 11 after springback, and simultaneously forms axial limiting, and the two cooperatively stably limit the elastic mounting part 3 in the mounting clamping groove 10, realizing reliable fixing of the spring buckle and the down lamp mounting clamping groove and avoiding relative displacement.

[0029] Therefore, the fixing can be completed by directly inserting the installation insertion rod 4 into the mounting clamping groove 10 of the down lamp, without the need of using additional connecting members such as screws and rivets, and without the need of using special tools; the assembly steps are greatly simplified, the operation time is shortened, the assembly efficiency of production and on-site installation is significantly improved, the labor input is reduced, and the labor cost is reduced.

[0030] In addition, the torsional spring ring 1 and the elastic mounting part 3 are integrally formed, without a split connection weak point, and have outstanding anti-fracture and anti-deformation capabilities; the U-shaped pressing part 2 connects the two torsional spring rings, guarantees the symmetry of the overall structure, and avoids structural damage caused by unbalanced single-side stress.

[0031] Further, the installation insertion rod 4 is vertically downwardly extended, and an inclination angle of 35-45° is formed between the installation insertion rod 4 and the limiting inclined rod 6.

[0032] Therefore, the vertically downward extension design of the installation insertion rod 4 can directly form axial alignment with the entrance of the mounting clamping groove 10, reduces positioning deviation during assembly, and improves alignment efficiency; the inclination angle of 35-45° optimizes the guide angle of the limiting inclined rod 6, efficiently converts elastic deformation during insertion, avoids blockage caused by excessive resistance, prevents insufficient deformation from affecting insertion smoothness, and significantly improves the smoothness and accuracy of assembly.

[0033] In the utility model, the tail end of the U-shaped pressing part 2 is provided with a jacket 41, and the jacket 41 is made of rubber or silicone.

[0034] When assembling the spring buckle, the operator holds the clamping sleeve 41 of the U-shaped pressing part 2, and the clamping sleeve 41 made of rubber or silica gel has good slip resistance on the surface, which can increase the friction between the hand and the U-shaped pressing part 2, avoid the buckle from slipping off due to sweating or uneven force during assembly, and improve the holding stability; at the same time, when the U-shaped pressing part 2 is installed in the mounting hole of the ceiling, the vibration energy in the work and environment of the down lamp can be absorbed, the impact of vibration on the locking structure of the elastic mounting part is reduced, the buckle loosening caused by long-term vibration is avoided, and the stability of the down lamp installation is further improved.

[0035] Referring to Figures 4-6 As shown in the drawings, the upper end of the spring buckle mounting seat 52 is provided with an upwardly extending extension seat 61, and the extension seat 61 is arranged between the two torsion spring rings 1.

[0036] Therefore, the lateral limiting and guiding effect of the extension seat 61 can guide the two torsion spring rings to be quickly and accurately positioned, avoid assembly misplacement, improve the assembly efficiency of the spring buckle and the down lamp mounting seat, and ensure the accurate alignment of the elastic mounting part and the mounting clamping groove; in addition, the extension seat 61 effectively prevents the two torsion spring rings 1 from deforming inwardly, and avoids the loosening and disengagement of the elastic mounting part caused by the inward deformation.

[0037] The mounting clamping groove 10 is provided with a stop block 71 at the lower end of the limiting block 11, and the stop block 71 is arranged between the two limiting inclined rods 6.

[0038] Therefore, the stop block 71 directly prevents the two limiting inclined rods 6 from deforming inwardly by rigid limiting, ensures that the limiting inclined rods 6 are always tightly abutted against the limiting block 11, avoids abutment failure or loosening, eliminates the risk of the buckle falling off and the down lamp falling caused by the inward deformation of the limiting inclined rods, and improves the installation safety.

[0039] The basic principle and main features of the present application and the advantages of the present application are shown and described in combination with the drawings, and those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principle of the present application, and various changes and improvements can be made to the present application without departing from the spirit and scope of the present application, and these changes and improvements all fall within the scope of the claimed present application.
