Description

Quick release structure of street light lamp holder

technical field

The utility model relates to a quick-detachable structure of a lamp cap of a street lamp, in particular to a quick-detachable structure of a lamp cap of an LED street lamp.

Background technique

Street lamps generally include a lamp post standing on the ground and a lamp cap installed on the upper part of the lamp post. The lamp cap includes a light source and a lampshade outside the light source. When installing, the lamp cap and the lamp post are fixedly connected by screwing or even welding. When a fault needs maintenance, it is troublesome to remove the lamp holder from the lamp post for maintenance, and even when welding and fixing, it is necessary to perform on-site maintenance work at the lamp holder. Due to the high position of the lamp head, it is very hard for the maintenance personnel to stay at a high place for a long time through long ladders and other operations, and there may even be a safety hazard.

Contents of the invention

The purpose of the utility model is to provide a quick-disassembly structure of the lamp cap of the street lamp, which is convenient to disassemble and assemble the lamp cap and the lamp post, which solves the problem of difficult disassembly and assembly of the street lamp and the lamp post during the installation and maintenance of the street lamp, and reduces potential safety hazards.

The technical solution of the utility model is: a quick-release structure of a lamp cap of a street lamp, comprising a first connecting piece fixed to the lamp post and a second connecting piece fixed to the lamp cap, the first connecting piece is provided with at least one locking piece , the locking piece includes a body with one axial end fixed to the first connecting piece and a head arranged at the other axial end of the body, the radial size of the head is larger than the radial size of the body, and the second connection The locking part is provided with a locking hole corresponding to the locking part. The locking hole includes an unlocking part whose radial dimension is larger than the head and a locking part whose radial dimension is larger than the body but smaller than the head. The locking part and The unlocking parts communicate with each other. When installing, you only need to align the unlocking part of the locking hole with the head of the locking piece and insert it so that the body of the locking piece is located in the unlocking part, and then move the lamp head so that the body reaches the locking part from the unlocking part of the locking hole Because the size of the locking part is between the body and the head of the locking piece, the locking piece and the locking hole are locked to each other, thereby making the lamp cap and the lamp post fixed. The procedure for removing the lamp holder from the lamp post is just the reverse of the above-mentioned installation procedure.

Further, in the above-mentioned quick-release structure of the lamp cap of the street lamp, the axial length of the body between the head and the first connecting piece is slightly larger than the axial thickness of the second connecting piece around the locking hole.

Further, in the above-mentioned quick-release structure of the lamp cap of the street lamp, the locking part of the locking hole is located above the unlocking part. In this way, due to the effect of the gravity of the lamp cap itself, when there is no external force, the locking member will not automatically unlock from the locking part of the locking hole to the unlocking part.

Further, in the above-mentioned quick-release structure of the lamp cap of the street lamp, the locking parts include several pieces arranged separately, and the locking holes are correspondingly provided with several pieces. The locking between the separately arranged locking pieces and the locking holes makes the connection between the lamp holder and the lamp post more reliable and stable.

The utility model advantage is:

1. The utility model makes the lamp cap and lamp post can be disassembled and assembled very conveniently through the locking holes fixed to the lamp cap and the lamp post respectively and the quick-release connection of the locking parts. When performing street lamp maintenance, only the street lamp cap can be replaced , convenient and safe, save the time for workers to repair lamps and increase safety; in addition, the shape of the lamp head can be easily replaced, making the use of street lamps more flexible and diverse.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

Embodiment: As shown in Fig. 1 to Fig. 4, a street lamp cap quick release structure, including a first connecting part 3 fixed to the lamp post 1 and a second connecting part 4 fixed to the lamp cap 2, the first connecting part 3 is provided with at least one locking piece 5, said locking piece 5 includes a body 51 fixed to the first connecting piece 3 at one axial end and a head 52 arranged at the other axial end of the body 51, said head 52 The radial dimension of the body 51 is larger than the radial dimension of the body 51. The second connecting member 4 is provided with a locking hole 41 corresponding to the locking member 51. The locking hole 41 includes a radial dimension larger than the head 52. The unlocking portion 411 and the locking portion 412 whose radial dimension is larger than the body 51 and smaller than the head 52 , the locking portion 412 and the unlocking portion 411 communicate with each other. Wherein the locking piece 5 is a screw or rivet fixed with one end of the first connecting piece 3, its body 51 and head 52 are all cylindrical, and the locking hole 41 is in the shape of a keyhole, that is, the unlocking part 411 is a circular hole.
