[0002] An existing Chinese utility model patent (authorization announcement number: CN206055309U) discloses a luminous body decoration device on a Christmas light string, which includes a lampshade, a socket and a light string; the light string includes a lamp head assembly and wires interconnected between the lamp head assemblies; the lampshade and the socket are snap-fitted and connected, and an inner hole is formed after the lampshade and the socket are snap-fitted and connected, and the inner hole cooperates with the lamp head assembly, and glue is filled between the inner hole and the lamp head assembly.

[0003] That is, the above structure fixes the lamp holder assembly in the inner hole by glue. Although the installation of the lamp holder assembly is relatively simple and can be fixed by simply applying the required glue, it is found during actual use that since the lamp holder assembly will emit heat when emitting light, the heat can easily cause the glue to soften and fail, and then the connection between the lamp holder assembly and the inner hole is separated, resulting in the problem of unstable and firm connection between the lamp holder assembly and the inner hole. Summary of the invention:

[0004] The purpose of the utility model is to provide a holiday lamp with a simple structure, reasonable design and low cost. A radially deformable limiting lip is used in the inner hole of the lamp holder to form a one-way limiting structure for the lamp beads, so that the lamp beads are stably connected between the lampshade and the lamp holder and will not fall off.

[0017] The present invention is further described below with reference to specific embodiments. Figure 1 —3:

[0018] A holiday lamp comprises a lamp holder 1 and a lampshade 2 connected to the front end of the lamp holder 1, a lead 4 is arranged between the lampshade 2 and the lamp holder 1 and passes through a lamp bead 3 at the rear end of the lamp holder 1, the lamp holder 1 is a cylindrical structure, and a plurality of limiting lips 5 with radially deformable inner ends are circumferentially distributed on the inner hole wall of the front end, the limiting lips 5 surround a conical channel 6 with a front end inner diameter smaller than a rear end inner diameter, the outer diameter of the lamp bead 3 is smaller than the front end inner diameter of the conical channel 6, the lamp bead 3 passes through the conical channel 6 from back to front, and the rear end face of the lamp bead 3 can axially limit against the inner end face of the limiting lips 5.

[0019] The utility model has a simple structure, reasonable design and low cost. A radially deformable limiting lip 5 is used in the inner hole of the lamp holder 1 to form a one-way limiting structure for the lamp bead 3, so that the lamp bead 3 is stably connected between the lampshade 2 and the lamp holder 1 and does not fall off.

[0020] Among them, in order to simplify the processing technology of the limiting lip 5 in the inner hole of the lamp holder 1, in this embodiment, the specific forming structure of the limiting lip 5 is: an annular cone sleeve with a smaller inner diameter at the front and a larger inner diameter at the back is provided on the inner hole of the lamp holder 1, and the rear end of the annular cone sleeve and the inner hole wall of the lamp holder 1 are an integrated structure, and the front end surface of the annular cone sleeve is evenly distributed with a plurality of cut-out grooves 7 in the circumferential direction, and the limiting lip 5 is formed between two adjacent cut-out grooves 7.

[0021] Furthermore, the lampshade 2 and the lamp holder 1 are detachably connected, that is, the lamp bead 3 is assembled as follows: the lamp bead 3 is passed through the rear port of the lamp holder 1 from back to front to the front side of the tapered channel 6 to achieve one-way limiting of the lamp bead 3; and the lamp bead 3 is disassembled as follows: the lampshade 2 and the lamp holder 1 are detachably separated, so that the lamp bead 3 can be removed from the front port of the lamp holder 1, and because the lead wire 4 of the lamp bead 3 passes through the inner hole of the lamp holder 1 at this time, the lead wire 4 can be cut off, or the limiting lip 5 can be expanded outward to make the lamp bead 3 exit the tapered channel 6 from front to back.

[0022] The detachable structure between the lampshade 2 and the lamp holder 1 may be that an inner thread is provided on the inner hole wall of the lamp holder 1 at the front side of the limiting lip 5, and an outer thread matching the inner thread is provided on the outer wall surface of the rear end of the lampshade 2. In this embodiment, the detachable structure between the lampshade 2 and the lamp holder 1 is that an annular protrusion 8 is formed on the inner hole wall of the lamp holder 1 at the front side of the limiting lip 5 and extends inwardly along its radial direction, the rear end of the lampshade 2 is inserted into the front end port of the lamp holder 1, and an annular groove 9 that can be snap-fitted with the annular protrusion 8 is provided on the outer wall surface of the rear end of the lampshade 2.

[0023] At the same time, in order to enable the lamp bead 3 to achieve better lighting coordination with the lamp shade 2, a flared groove 10 is opened at the front end port of the lamp holder 1, the rear end of the lamp shade 2 is inserted in the flared groove 10, and the annular protrusion 8 is arranged on the groove side wall of the flared groove 10, and the inner end of the limiting lip 5 is located in the flared groove 10 and the rear end port of the lamp shade 2, and in the present embodiment, the inner end outer wall surface of the limiting lip 5 can be radially limited and abutted against the rear end inner hole wall of the lamp shade 2, that is, the lamp bead 3 must first be passed through the conical channel 6, and then the lamp shade 2 must be plugged and buckled on the lamp holder 1 to complete the assembly of the lamp bead 3, the lamp shade 2 and the lamp holder 1.

[0024] The above embodiment is only one of the preferred embodiments of the present invention, and is not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes made based on the shape, structure, and principle of the present invention should be included in the protection scope of the present invention.
