Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

Fig. 1-5 show a preferred embodiment of the waterproof lamp according to the present invention. The waterproof lamp in the embodiment comprises a shell 1, a lamp bead 2 and a lens 3; the lamp beads 2 are arranged on the lamp bead plate 14. The upper end surface of the housing 1 is provided with a slot 4 along the edge of the housing 1, as shown in fig. 3 and 5, the slot 4 is used for filling glue, and the lens 3 is sealed on the upper end surface of the housing 1. For the convenience of installation, the corner position of the upper end surface of the housing 1 is further provided with a limiting block 5, the limiting block 5 is used for limiting the lens 3 on the upper end surface of the housing 1, in this embodiment, the housing 1 is rectangular, each corner of the housing 1 is provided with two limiting blocks 5, the two limiting blocks 5 are arranged in the slot 4, the planes of the two limiting blocks are perpendicular to each other, and the corners of the lens 3 are limited. Secondly, a plurality of grooves 6 are recessed in parallel on the lower end surface of the outer side of the shell 1 along the length direction of the shell 1; due to the design, the shell 1 is more elegant, beautiful and small, and the heat dissipation of the lamp is facilitated. Further, lamp pearl 2 is fixed in the lower terminal surface of shell 1 inboard through the fastener, and the fastener in this embodiment can be screw, bolt etc..

As shown in fig. 3-5, in order to solve the problem of poor waterproof sealing performance of the lamp in the prior art, the lamp in this embodiment further includes a locking member 7 and a tapered sealing ring 8. One side of the housing 1 in this embodiment is provided with a stepped hole 9. Wherein, the end with large diameter of the stepped hole 9 is communicated with the outer side of the shell 1, and the end with small diameter is communicated with the inner side of the shell 1. The middle part of retaining member 7 is provided with first through-hole 10, and 8 middle parts of conical seal are provided with second through-hole 11, and first through-hole 10 and second through-hole 11 are used for supplying the cable conductor to stretch into in the shell 1, with 2 electric connection of lamp pearl. The tapered sealing ring 8 comprises a cylindrical end 81 and a tapered end 82, the diameter of the cylindrical end 81 is larger than that of the end with the smaller diameter of the stepped hole 9, the tapered end 82 is inserted into the end with the smaller diameter of the stepped hole 9 from outside to inside, and the end surface of the cylindrical end 81 is abutted to the locking part 7; the locking piece 7 is arranged at one end of the stepped hole 9 with a larger diameter and is in locking fit with the shell 1 to press the conical sealing ring 8 in the stepped hole 9.

This waterproof lamp utilizes the cooperation of shoulder hole 9, taper seal 8 and retaining member 7 ingeniously, pegs graft in the direct little one end of shoulder hole 9 outside-in with taper end 82 of taper seal 8, recycles retaining member 7 and compresses tightly taper seal 8 in shoulder hole 9. At this time, as the locking member 7 generates a pressure on the tapered sealing ring 8, the tapered end 82 of the tapered sealing ring 8 is extruded and deformed towards the directly smaller end of the stepped hole 9, and the outer wall of the tapered end 82 is further attached to the inner wall of the stepped hole 9; meanwhile, as the tapered end 82 is extruded and deformed, the side wall of the second through hole 11 corresponding to the end shrinks like a claw to grasp the cable, so that the inner wall of the tapered sealing ring 8 at the position is more attached to the outer wall of the cable. Compared with the existing lamp, the sealing ring can be well attached to the inner wall of the shell or the outer wall of the cable, so that the sealing and waterproof performance of the lamp can meet the requirements. In addition, in this embodiment, the locking member 7 is preferably a nut that is threadedly engaged with the stepped bore 9.

Further, since the locking member 7 is screwed inward during installation, and the end surface of the taper seal ring 8 in contact with the locking member may be worn during screwing, in the present embodiment, a protective ring 12 is provided between the locking member 7 and the taper seal ring 8, as shown in fig. 3, and the protective ring 12 is mainly used for separating the locking member 7 and the taper seal ring 8, so as to prevent the taper seal ring 8 from being damaged when the locking member 7 is locked. The protective ring 12 in this embodiment is chosen to be a washer.

Further, as shown in fig. 1-3, the lamp of the present embodiment is further provided with a bracket 13, and the bracket 13 is used for connecting the lamp with the outside, such as installing the bracket 13 on the ground, or hanging the bracket 13 on a wall, etc. The bracket 13 in this embodiment is provided at the cable connection end and is connected to the housing 1 by screws or bolts.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
