Description

Technical Field

[0001] The utility model relates to the technical field of drilling equipment, in particular to a water injector device for drilling with an angle grinder. Background Art

[0002] On the kitchen stove, marble or hard tiles often need to be installed with holes to install gas pipes or other accessories. Since marble and tiles are hard materials, using an angle grinder for drilling is an efficient choice. At the output end of the angle grinder, there is a special connector that can be tightly connected to the drill bit. This connection method ensures efficient transmission of power, allowing the drill bit to rotate smoothly and penetrate hard surfaces.

[0003] When drilling stones with an angle grinder and a water injector, the drill bit is often damaged due to overheating due to the high hardness of the stone. This limits the efficiency of the drilling operation to a certain extent. The drill bit itself does not have the function of injecting water to remove debris during the drilling process, which not only increases the risk of drill bit blockage, but also reduces the efficiency of the entire drilling operation. Utility Model Content

[0004] The utility model aims to provide a water injector device for drilling holes of an angle grinder, so as to solve the technical problem that it is inconvenient to inject water into the drill bit to clean the debris proposed in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a water injector device for drilling holes on an angle grinder, comprising a water injector body, a rotating block is arranged inside the water injector body, a bearing is fixedly mounted on the rotating block, two groups of limit retaining springs are fixedly mounted on the rotating block, and the limit retaining spring is located on one side of the bearing, a limiting assembly is arranged on the water injector body, a water injection head is installed on the water injector body, a No. 1 connecting head is fixedly mounted on the top of the rotating block, a No. 2 connecting head is fixedly mounted on the bottom of the rotating block, a No. 1 flow channel is arranged inside the rotating block, a threaded barrel is threadedly connected to the No. 2 connecting head, a support rod is fixedly mounted on the bottom end of the threaded barrel, a drill bit is fixedly connected to the bottom end of the support rod, a No. 2 flow channel is arranged inside the support rod, and two groups of sealing blocks are symmetrically mounted on the rotating block.

[0006] Preferably, a hose is connected to the water injection head.

[0007] Preferably, the No. 1 flow channel runs through the interior of the rotating block.

[0008] Preferably, the No. 1 flow channel is connected to the No. 2 flow channel, and the No. 2 flow channel passes through the support rod.

[0009] Preferably, the limiting assembly comprises a limiting shaft and a connecting piece, the limiting shaft is fixedly mounted on the water injector body, and the connecting piece is movably connected to the limiting shaft.

[0010] Preferably, a limiting hole is provided on the connecting piece.

[0011] Preferably, the sealing block is located on one side of the bearing, and a groove corresponding to the sealing block is provided inside the water injector body.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model is convenient for the angle grinder drilling water injector device to inject water to the drill bit through the installed water injector body. After the drill bit is moved to the material drilling location, the external water delivery mechanism works, and after the water source is transmitted to the inside of the water injector body, the water source will flow into the inside of the No. 1 flow channel, and then flow into the No. 2 flow channel and then flow out to one side of the drill bit. At the same time, the angle grinder will also drive the rotating block to rotate inside the water injector body through the No. 1 connecting head. When the rotating block rotates, it will drive the drill bit to rotate through the No. 2 connecting head, the threaded cylinder and the support rod, and then the drill bit will drill a hole in the stove marble or hard porcelain, so as to achieve the purpose of making up the circumference of the drill bit at a small speed. At the same time, the water source flows to discharge the excrement in the drill hole, so as to avoid the occurrence of the phenomenon of drill jamming and the decrease of drilling efficiency. At the same time, water is injected into the drill bit to flow outward, which can cool the drill bit, thereby improving the drilling efficiency and making the drill bit more pressure-resistant and wear-resistant, thereby improving the practicality of the angle grinder drilling water injector device.

[0014] 2. The utility model can improve the installation stability of the water injector device for drilling holes on an angle grinder by installing a connecting piece. The limiting shaft limits the connecting piece, and the connecting piece can make circular motion around the limiting shaft. When the water injector device for drilling holes on an angle grinder is installed and used, a threaded hole corresponding to the limiting hole is provided on the angle grinder. After the connecting piece is moved to drive the limiting hole and the threaded hole to coincide with each other, a bolt is passed through the limiting hole and threadedly connected to the threaded hole, thereby limiting the position of the connecting piece. The position of the water injector body is limited by the connecting piece and the limiting shaft, thereby improving the installation stability of the water injector device for drilling holes on an angle grinder.
