Description

A light pole support structure

[technical field]

The utility model relates to a lamp post supporting structure on a lamp.

[Background technique]

With the improvement of living standards, lighting products are gradually loved by people. If they can be matched with appropriate lighting in interior decoration, they will have both practical and beautiful functions. Most of the general table lamps or desk lamps are composed of lamp base and lamp pole. The lamp base mainly enables the lamp to be placed on the table or platform stably, while the lamp pole can be adjusted to the appropriate lighting position according to the user's angle of use. , The connection between the light pole and the light pole is mostly fixed by the bolt and the fixed knob. The fixed knob is used to control the swing and screw between the light pole and the light pole, so that the light pole and the light pole can be moved by the bolt and the fixed knob. To achieve the adjustment of the light pole angle. Due to the use of bolts to fix, it is very inconvenient to assemble and adjust. To this end, the manufacturer has improved the light pole.

The existing light poles generally use the plug-in method for cooperation between the light poles, that is, the light support poles are made into a hollow shape, and then one end of the plastic pivot frame is accommodated in the support poles, and through the support poles and the pivot frame The cards and card slots that can be engaged with each other cooperate to achieve the effect of anti-loosening and fastening connection. However, this structure has the disadvantage of concentrated force, and the plastic pivoting frame is easy to age. When the user adjusts the lamp, the end of the pivoting frame is easily broken due to a large force, and the service life is short.

[utility model content]

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a light pole support structure with convenient assembly, long service life and high strength.

In order to solve the above-mentioned technical problems, the utility model adopts the following technical solutions:

A light pole support structure, including a support rod and a pivot frame, the front and rear ends of the pivot frame are respectively formed with a rotating shaft connection part and a support rod clamping core, the support rod is hollow, and the above support rod clamping core is fixedly installed on In the support rod, it is characterized in that a metal core that enhances the bending resistance of the clamping part is installed in the support rod core;

A light pole support structure as described above is characterized in that there is a hole on the support pole, and a screw hole is correspondingly provided on the core of the support pole, and a locking screw passes through the hole and connects with the core of the support pole. threaded connection;

A light pole support structure as described above is characterized in that the pivot frame includes upper and lower shells that are closely bonded, an upper groove is opened on the rear of the upper shell, and a lower groove is correspondingly opened on the rear of the lower shell , the metal core is clamped in the cavity formed by the upper and lower grooves with an interference fit;

A light pole support structure as described above is characterized in that a protrusion and a groove are respectively provided at the junction of the upper shell and the lower shell, and the protrusion and the groove are combined after ultrasonic treatment.

The beneficial effects of the utility model are:

1. A metal core is clamped with interference fit in the core of the support rod. The function of the metal core is to enhance the bending resistance of the joint between the pivot frame and the support rod, and prevent the pivot joint from being damaged when adjusting the lamp on the pivot frame. The frame is broken, prolonging the service life of the utility model;

2. There is a hole on the support rod, and a screw hole is correspondingly provided on the support rod card core at the rear end of the pivot frame. A locking screw passes through the above hole and is threadedly connected with the support rod card core. When installing, only the support rod and The two corresponding ends of the pivot frame can be sleeved and tightened with screws, which is convenient for installation.

[Detailed ways]

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

As shown in the figure, a light pole support structure includes a support rod 1 and a pivot frame 2. The front and rear ends of the pivot frame 2 are respectively formed with a rotating shaft connection part 21 and a support rod clamp 20. The support rod 1 is Hollow, the above-mentioned support rod clamp 20 is fixedly installed in the support rod 1, and a metal core 3 is mounted inside the support rod clamp 20 to enhance the bending resistance of its locking part.

Wherein, the pivot frame 2 includes upper and lower shells 23, 24 tightly bonded, the upper shell 23 is provided with an upper groove 230, and the lower shell 24 is correspondingly provided with a lower groove 240, and the metal core 3 interferes Fittingly clamped in the cavity formed by the upper groove 230 and the lower groove 240 , the function of the metal core 3 is to enhance the breaking resistance of the supporting rod core 20 on the pivot frame 2 .

In the utility model, the upper shell 23 and the lower shell 24 are made of plastic, and the cost is low. The inner side of the lower shell 24 is provided with a plurality of clamping holes for positioning and connection, and the upper shell 23 is provided with a plurality of protruding posts extending downward, and each protruding post is correspondingly clamped in each of the above-mentioned clamping holes, which is very convenient to assemble; At the same time, the combined periphery of the upper shell 23 and the lower shell 24 can also be respectively provided with a convex portion 25 and a groove 26, and the convex portion 25 and the groove 26 are combined after ultrasonic treatment, so that the upper shell 23 and the lower shell 24 They are glued together more firmly to form the pivot frame 2 .

A hole 11 is opened on the support rod 1 , and a screw hole 200 is correspondingly provided on the support rod clamp 20 , a locking screw 4 passes through the hole 200 and is threadedly connected with the support rod clamp 20 . In this way, it is convenient to insert the support rod clamp 20 into the support rod 1 and make the two fit closely and firmly.
