Description

Opening device for circular frameless recessed projection lamp

This new model is about a hole-drilling device for lamps, especially a circular frameless recessed projection lamp. The hole-drilling device provided by this model can avoid cracking or chipping of the sinking part when opening the hole .

Press, the existing hole drilling tool for the circular frameless recessed projection lamp is to use a hole drill, as shown in Figure 1, after the ceiling 4 or gypsum board is drilled through the hole drill, and then use a grinding wheel, etc. The tool is ground to form a sinking hole 41 for the ceiling 4 to install a circular frameless recessed projection lamp. However, in the aforementioned way, the center of the sinking hole 41 is not concentric, which leads to the need for follow-up after installation. Decorative touches.

Therefore, some manufacturers have developed a hole opener for countersunk holes. Related cases are as follows: Chinese Patent No. CN207681558U. After the hole, the tool can enter the ceiling to process the sunken table, and the depth of the sunken table can be adjusted by using the positioning plate; however, the lack of the above products is that when the sunken table is processed, the resistance is relatively large, and it is easy to open the hole The deflection of the device scrapes off the parts that do not need to be processed, in other words Even if the hole is expanded and the sinking part is easy to crack, it needs to be repaired with materials such as gypsum and filling soil to make the ceiling flat.

The design of the above-mentioned equipment is quite unsatisfactory, and how to solve the lack of the above-mentioned equipment is a problem that the relevant industry is actively solving.

The main purpose of this new model is to provide a hole-drilling device for a circular frameless recessed projection lamp. The conventional hole-drilling device is equipped with a limit wheel, and the tool used for processing the sinking part includes a guide part and a It is composed of a processing part. In this way, the hole-drilling tool will not be deflected when the hole is drilled by using the limit wheel, and the tool first cuts the local sinking part with the guide part, and then the processing part completes the processing of the sinking part. Avoid the complex process of sinkhole cracking and subsequent repair.

For this reason, the structure of the present invention includes: a hole opening tool, a sinking tool and a plurality of limit wheels;

The aforementioned hole cutting tool is used to process a housing hole for installing a circular frameless recessed projection lamp. The hole cutting tool is cylindrical, and the top edge of the hole cutting tool has a plurality of serrations. The bottom of the hole cutter is provided with multiple connection holes;

The sinking tool is used to process a sinking position at the bottom of the aforesaid accommodating hole. The sinking tool is provided with a plurality of radially arranged blades. The sinking tool is provided with a plurality of positioning holes, through which a plurality of Screws pass through the connection holes and the positioning holes in sequence, so that the hole opening tool and the sinking platform The knives are combined together, and the outer edge of each knife plate is provided with a guide part and a processing part. The aforementioned guide part is arranged on the outside of the hole opening tool, and when the guide part is processed at the sinking platform, it is at the edge of the accommodating hole. A guide groove is formed on the outer edge of the bottom, the processed part is arranged at the rear end of the guide part, and the processed part is cut along the guide groove so that the bottom of the accommodating hole forms the sunken platform part; An L-shaped plate is arranged between the processing parts, and the aforementioned limiting wheel train is installed on the L-shaped plate, so that the sinking tool is driven by the limiting wheels to produce circular motion during processing.

In an embodiment of the present invention, a center drill is further provided in the center of the drilling tool, and the center drill extends toward the side of the counter tool to form a shaft for tool clamping.

In the embodiment of the present invention, wherein, the guide part and the processing part are respectively provided with a groove, the aforementioned guide part and the processing part are arranged in each of the grooves, by adjusting the guide part and the processing part in each of the The position of the groove, and then adjust the range and depth of the sinking platform.

Through the above description, the features and effects of the new model are briefly described as follows:

1. The new model uses a limit wheel, so that when the sinking tool is processing the sinking part, it can cut out a smooth sinking part, avoiding the cracking of the sinking part, and subsequent complex processes such as plaster repair.

2. Further, a centering drill bit can be installed on the hole opening tool, so that when drilling the accommodation hole, it can be accurately processed at the required position superior.

3. The position of the guide part and the processing part can be adjusted by using the groove, and then the range and depth of the sinking part can be adjusted. In other words, the new structure can be applied to different types of round frameless recessed projection lamps, all of which can be used. Process the required sinking platform parts.
