Description

Prefabricated street lamp pole

The present invention relates to a prefabricated street lamp, in particular, the lower end of the guide cap is screwed to the screw cap coupled to the upper end of the lower column, and the upper column is inserted into the guide cap screwed to be fixed by the tightening force of the screw. .

In general, street lamps are generally long and heavy, so that the lengths of the posts are divided into several equal parts, and then the posts separated from the place to be installed are connected to each other. In this case, the diameter of the lower column is made larger than that of the upper column.

As shown in FIG. 1, the street lamp 60 has a lower column 61 installed on an upper portion of the ground 70 by a flange 62 formed at a lower end of the lower column 61, and the lower column 61. At the upper end of the) is configured such that the lower portion of the upper support 63 having a form gradually decreasing toward the upper portion is coupled by a connection member 64 having a separate tapered shape. The upper end of the upper support 63 is configured such that the luminaire arm 66 to which the luminaire 65 is coupled is coupled.

The street lamp 60 has the upper column 63 and the lower column 61 separated from each other in the process of the lower end of the upper column 63 is connected through a separate connecting member 64 on the upper portion of the lower column 61. There was a difficulty in the welding joint work to match the center of the upper support 63 by using the connecting member 64 in the upper center of the lower support 61 by being in a state of being, because of this difficulty, a lot of working time There was another issue that took place.

In addition, it is impossible to use heterogeneous materials as it is coupled to the welded joint, and thus there is a problem of inhibiting the aesthetics of the surroundings as it is used as a uniform material.

And when broken and damaged after installation, there was a problem that the partial replacement is impossible and the compatibility is lowered.

The present invention is to ensure that the lower end of the guide cap is screwed to the screw cap coupled to the upper end of the lower column, and the upper column is inserted into the guide cap to be screwed to be fixed by the fastening force of the screws, respectively, the lower column and the guide cap and The upper column can be separated to make it easy to manufacture, transport and install, and to be made of different or the same material to enhance the aesthetics and improve the compatibility and to make partial replacement, and to taper the lower part of the guide cap. It is an object of the present invention to provide a prefabricated street lamp that can be easily inserted into the screw cap to improve the workability by forming an insertion guide having a true shape.

The present invention is a screw cap 20 is a prefabricated type configured to be coupled to the guide cap 30 to the upper end of the lower column 10 is welded, the lower end of the upper column 40 to the guide cap 30 In the street lamp, the screw cap 20 has a lower end larger than the diameter of the lower column 10, the welding joint 50 is coupled to the state mounted on the lower column 10, the upper end is narrower than the lower end, the upper center The female thread groove 21 is integrally formed therein, and the guide cap 30 has a male thread guide 32 having a locking jaw 31 formed therein in a hollow shape, and an upper portion at the top where the locking jaw 31 is formed. Withdrawal guide 33 extending to narrow to the integrally formed is characterized in that the male screw guide 32 is coupled to the female screw groove 21.

In addition, the male thread guide 32 is formed integrally with the insertion guide 34 having a form of gradually narrowing the diameter at the lower end, it is caught so that the lower end of the upper support 40 is supported by the insertion guide 34 It features.

In addition, the drawing guide 33 is formed in a curved shape and is formed with a plurality of screw grooves 35 toward the center on the narrowed surface, and is fastened by the fastening force of the screws 36 coupled to the screw grooves 35. The lower end of the upper support 40 is characterized in that it is fixed.

The present invention is to ensure that the lower end of the guide cap is screwed to the screw cap coupled to the upper end of the lower column, and the upper column is inserted into the guide cap to be screwed to be fixed by the fastening force of the screws, respectively, the lower column and the guide cap and The upper column can be separated to obtain an effect of facilitating manufacture, transportation and installation.

In addition, each of the lower column, screw cap and guide cap and the upper column is made of different or the same material to make aesthetics stand out, and because it is in a separated form, it is easy to replace due to partial damage. Can be obtained.

And by forming an insertion guide having a tapered form in the lower portion of the guide cap can be easily inserted into the screw cap can further obtain the effect of improving the workability.

Hereinafter, the present invention will be described with reference to the accompanying drawings.

Prefabricated street lamp according to the present invention as shown in Figures 2 to 5 has a lower arm 10, a screw cap 20, a guide cap 30 and a luminaire arm 42 fixed to the luminaire 41 on the top Consists of a combined upper column 40.

Here, the lower column 10 has a hollow shape and is configured such that the lower end of the screw cap 20 is coupled to the welding joint 50 in advance.

The screw cap 20 is coupled to the welding joint 50 in a state where the lower end is larger than the diameter of the lower column 10 is mounted on the lower column 10, the upper end is narrower than the lower end, female thread groove in the center of the upper end 21 is integrally formed.

The guide cap 30 has a male thread guide 32 having a locking jaw 31 formed in a hollow shape, and an extension guide 33 extending to be narrowed to an upper portion at an upper end of the locking jaw 31 is integrally formed. The male thread guide 32 is formed to be coupled to the female thread groove 21 of the screw cap 20.

The male thread guide 32 has an insertion guide 34 having a form of gradually narrowing in diameter at its lower end and is easily inserted into the center of the female thread groove 21 formed at the center of the screw cap 20. At the same time, the lower end of the upper support 40 is configured to be supported.

The withdrawal guide 33 has a function of easily coupling the lower column 10 and the upper column 40 with different diameters. The withdrawal guide 33 is narrow in a curved shape and centered on a narrowed surface. A plurality of screw grooves 35 are formed to face the lower end of the upper column 40 by the screws 36 coupled to the screw grooves 35.

Such prefabricated street light is first coupled to the lower end of the screw cap 20 to the upper end of the lower column 10 having a hollow shape coupled to the flange 11 at the bottom and then joined with a welding joint 50 along the circumference To be done.

Next, the pull guide 33 of the guide cap 30 is inserted into the lower end of the upper support 40, and then the upper support is held by the tightening force of the screw 36 by engaging and tightening the screw 36 to the pull guide 33. The guide cap 30 is fixed to the lower end of the 40.

Next, the lower portion of the guide cap 30 is inserted into the female thread groove 21 of the screw cap 20 coupled to the upper end of the lower support 10, and at the same time, automatically by the inclined surface or the taper of the insertion guide 34 This coincidence is inserted so that the start end of the male guide 32 abuts against the female thread groove 21. At this time, the lower end of the upper column 40 is caught by the insertion guide (34).

In this state, the guide cap 30 is coupled to the screw cap 20 by rotating the upper support 40 or releasing the screw 36 to rotate the guide cap 30.
