Referring to fig. 1 to 3 in combination, the present embodiment provides an elastic positioning device 100 that can be used for mounting on a lamp body, the elastic positioning device 100 being located between a mounting surface and the lamp body. The elastic positioning device 100 comprises a fixed base 1 and an elastic ring 2 on the fixed base 1, and the elastic positioning device 100 utilizes the characteristic of the elastic ring 2 to realize quick and convenient installation and simultaneously adjust the assembly gap between the lamp body and the installation surface.

Specifically, the elastic ring 2 is a non-closed ring body made of spring steel wires through multi-section bending molding. The elastic ring 2 comprises a fixing part 21 and an adjusting part 22, wherein the adjusting part 22 inclines outwards relative to the fixing part 21 and is symmetrically arranged at two ends of the fixing part 21 in a double-wing mode, so that the stress of the elastic ring 2 in the using process is uniform. The fixing portion 21 is provided with a first fixing edge 211 and a second fixing edge 212 which are parallel to each other, a cut-out 213 is formed in the middle of the first fixing edge 211, and the second fixing edge 212 has a complete linear structure.

Correspondingly, the fixed base 1 is formed by stamping a sheet metal part and is provided with a first limiting part 11 and a second limiting part 12. In this embodiment, the first limiting member 11 protrudes upward from the fixing base 1, the whole structure is a cylinder after being cut, and the first limiting member 11 is disposed in a direction that the axis is parallel to the first fixing edge 211. In addition, the first stopper 11 is provided with a through hole 111 penetrating the first stopper 11 along the axial direction. The second limiting member 12 is located on the opposite side of the first limiting member 11. The second limiting member 12 is a hook-shaped structure formed by stamping the fixed base 1, the whole second limiting member 12 is L-shaped, and a bayonet 121 is arranged on one side facing the first limiting member 11.

The elastic ring 2 is fixed on the fixed base 1 through a first limiting piece 11 and a second limiting piece 12. During installation, the first fixing edge 211 is pulled to increase the distance between the interruptions 213 until the portions of the first fixing edge 211 on both sides of the interruptions 213 are inserted into the through holes 111 of the first limiting member 11. At this time, the first fixing edge 211 is restored to the original state under the action of the reversible elastic deformation, the distance between the fracture 213 is reduced, and the first fixing edge 211 is integrally inserted and clamped in the through hole 111, thereby fixing the first fixing edge 211. At the same time, the second fixing edge 212 passes through the bayonet 121 to be engaged with the inside of the second stopper 12, thereby fixing the second fixing edge 212. The mounting mode matched with the clamping through pulling is quick and simple, the assembly efficiency is improved, and meanwhile, the assembly cost is saved. In the present embodiment, two second stoppers 12 are provided at intervals on the fixing base 1 to ensure the stability of fixing the elastic ring 2.

Further, when the elastic ring 2 is mounted on the fixed base 1, the elastic ring 2 is perpendicular to the fixed base 1 on a projection plane of the fixed base 1, so that the adjusting portions 22 protrude from two ends of the fixed base 1. The adjusting portion 22 further includes a connecting portion 221 and an abutting portion 222, and the connecting portion 221 is formed obliquely upward and outward from both ends of the fixing portion 21 and connects the abutting portion 222. An abutment surface 223 for abutting against the lamp body is formed between the parallel spring wires at the abutment portion 222, and the abutment surface 223 is parallel to the plane in which the fixing portion 21 is located. The contact portion 222 is further provided at its most opposite ends with a protector 224 inclined toward the plane of the fixed base 1, and the protector 224 is connected to the contact surface 223 and is separated from the connection portion 222. When the elastic positioning device 100 is used for being installed between the lamp body and the installation surface, the spring steel wire at the abutting surface 223 is attached to the surface of the lamp body, and the protecting body 224 is bent towards the side far away from the surface of the lamp body. At this time, the elastic ring 2 is formed by bending the spring steel wire in a plurality of steps, and has elasticity, so that the elastic ring can be clamped between the lamp body and the fixed base 1, and the gap between the lamp body and the mounting surface is adjusted by using the elasticity, so that the balance and the tightness of the lamp body are ensured. Wherein, the protection body 224 that is away from the lamp body surface and buckles plays the effect of reducing the lamp body surface scratch.

In addition, in order to ensure the stability of the structure of the elastic positioning device 100 during installation, the fixed base 1 is further provided with a limiting step 13. The limiting steps 13 vertically protrude upwards from the two ends of the fixed base 1, so that the fixed base 1 is formed with an inward concave sinking table 14. The fixing portion 21 is fixed to the first stopper 11 and the second stopper 12 located inside the sink table 14, and the adjusting portion 22 protrudes from both ends of the sink table 14. Correspondingly, a reinforcing part 23 is arranged between the fixing part 21 and the adjusting part 22, and a spring steel wire at the reinforcing part 23 vertically extends upwards from two ends of the fixing part 21 and is attached to the limiting step 13. Wherein, the cooperation of spacing step 13 and reinforcing part 23 has realized further spacing to elastic ring 2, has also increased the structural stability of elastic ring 2 in the use simultaneously.

In summary, the elastic positioning device 100 provided in the present embodiment adjusts the assembly gap of the lamp body by using elasticity. The elastic ring 2 is formed by bending a spring steel wire, and is provided with symmetrically arranged adjusting parts 22, so that bilateral stress is uniform and elasticity is achieved. And the manufacturing process of the elastic ring 2 does not need to open a die, and can cut according to the target length, thereby reducing the process cost and reducing the material waste. The fixed base 1 is provided with the concave sinking platform 14 and the first limiting piece 11 and the second limiting piece 12 inside the concave sinking platform 14 through a stamping process, the elastic ring 2 is fixed at the concave sinking platform 14, and the positioning of the elastic ring 2 is easily realized. Simultaneously, the elastic ring 2 utilizes the reversibility of elastic deformation, the fracture 213 is pulled open and the clamping and the fixing with the first limiting piece 11 are completed, and the other end is clamped with the second limiting piece 12, so that the convenient and quick assembly is realized.

Example 2

Referring to fig. 1 to 4 in combination, the elastic positioning device 100 further includes a buffer member 3, where the buffer member 3 is sleeved outside the abutting portion 222 of the elastic ring 2.

Because the elastic ring 2 is formed by bending the spring steel wire in a plurality of times, when the elastic ring 2 is installed with the lamp body, the abutting part 222 of the elastic ring is in direct contact with the surface of the lamp body by the linear spring steel wire, and the contact area is small, so that larger pressure is generated when the elastic ring is clamped, and the surface of the lamp body is easy to scratch. The buffer member 3 is integrally in a sleeve-shaped structure, and is provided with a first buffer portion 31 and a second buffer portion 32, wherein the first buffer portion 31 is matched with a portion, provided with an abutting surface 223, of the elastic ring 2, and the second buffer portion 32 is symmetrically arranged at two ends of the first buffer portion 31 and is respectively matched with a portion of the connecting portion 221 and the protecting body 224.

The buffer member 3 is sleeved outside the abutting portion 222, so that the contact area between the abutting portion 222 and the surface of the lamp body is increased, and on one hand, the surface of the lamp body is prevented from being scratched, so that a buffer effect is achieved. On the other hand, the buffer piece 3 converts the dotted line contact between the elastic ring 2 and the surface of the lamp body into the surface contact, so that the stress of the elastic ring 2 is more uniform, the balance and the tightness of the lamp body during installation are better regulated, and the durability of the elastic force of the elastic ring 2 is ensured.

Referring to fig. 1, 4 and 5 in combination, when the lamp is fixed to the mounting surface 5, the abutting portion 222 of the elastic ring 2 abuts on the upper surface of the lamp via the abutting surface 223. The elastic ring 2 is formed by bending spring steel wires in multiple ways and has a double-wing-shaped structure, so that the elastic ring has elasticity. Along with the lamp body 4 approaching to the mounting surface 5, the adjusting part 22 of the elastic ring 2 is mainly stressed along the bending direction of the connecting part 221, so that the whole elastic ring 2 is uniformly stressed and correspondingly elastically deformed, thereby adjusting the assembly gap between the lamp body 4 and the mounting surface 5 and improving the fastening performance and flatness.

Meanwhile, on the projection plane where the fixed base 1 is located, the elastic ring 2 is perpendicular to the fixed base 1, so that the stress direction and the stress area of the surface of the lamp body 4 are expanded, and the installation of the lamp body 4 has balance. The elastic ring 2 is fixed to the first stopper 11 by the fracture 213 by utilizing elastic deformation reversibility, and is engaged with the second stopper 12.
