Detailed Description
Referring to fig. 1-6, in the embodiment of the present invention, an expansion screw mounting sleeve includes a mounting barrel 1 and a sleeve head 2 integrally connected to the mounting barrel 1, the mounting barrel 1 and the sleeve head 2 are integrally formed, an inner clamping groove 3 is disposed on a terminal surface of the sleeve head 2, a drill rod channel 4 is disposed at an inner center of the mounting barrel 1, and two symmetrical drill tip chutes 5 are disposed outside the drill rod channel 4 inside the mounting barrel 1.
In fig. 3: a horn-shaped notch 6 is formed in the sleeve head 2 at one end, connected with the mounting barrel 1, of the inner clamping groove 3, the maximum inner diameter of the horn-shaped notch 6 is matched with the inner diameter of the inner clamping groove 3, the minimum inner diameter of the horn-shaped notch 6 is matched with the distance between the inner walls of the two drill nozzle sliding grooves 5, and the horn-shaped notch 6 is designed at the tail end, located in the inner clamping groove 3, of the sleeve head 2, so that when the impact drill nozzle moves back, the drill nozzle sliding grooves 5 can be found more easily and can slide into the drill nozzle sliding grooves 5;
in fig. 2 and 3: one end of a drill nozzle sliding groove 5 is communicated with the inner clamping groove 3, the other end of the drill nozzle sliding groove 5 extends into the installation barrel 1 and does not penetrate through the tail end of the installation barrel 1, the length of the drill nozzle sliding groove 5 is smaller than that of the drill rod channel 4, the drill nozzle sliding groove 5 is designed to be shorter than that of the drill rod channel 4, and the rear end of the drill nozzle sliding groove does not penetrate through the tail end of the installation barrel 1, so that after the percussion drill bit penetrates through the installation sleeve and is connected with the percussion drill, the percussion drill is formed by welding hard alloy, the diameter of the drill bit is larger than the inner diameter of the drill rod channel, the installation sleeve cannot fall off from the percussion drill in the use process, it needs to be noted that the size of the drill nozzle sliding groove 5 is slightly larger than that of the percussion drill nozzle of the percussion drill, the drill nozzle of the percussion drill can slide smoothly in the drill nozzle sliding groove 5, and the percussion drill bit structure on the market is the same, the drill bit (i.e. the drill nozzle) is larger than the drill rod, the part larger than the drill rod is made of hard alloy, and the alloy is sintered at the top end of the drill rod in a straight line shape, so that the drill nozzle sliding groove 5 and the drill rod channel 4 are designed, and the impact drill nozzle can slide in the installation barrel 1.
In fig. 2-5: one end of the drill rod channel 4 is communicated with the inner clamping groove 3, the other end of the drill rod channel 4 penetrates through the tail end of the installation barrel body 1, and the drill rod channel 4 is cylindrical; the drill rod channel 4 and the drill nozzle sliding groove 5 are of an integrally formed structure, the size of the drill rod channel 4 is slightly larger than that of a drill rod of the percussion drill bit, the drill rod of the percussion drill bit can slide smoothly in the drill rod channel 4 conveniently, and the percussion drill bit comprises a drill rod and a drill nozzle;
the inner clamping groove 3 is in an inner hexagon shape (shown in figure 4) or an inner plum blossom shape (shown in figure 6), and the inner diameter size of the inner clamping groove 3 is matched with the size of a nut of the expansion screw.
The utility model discloses a theory of operation is: when the installation sleeve is installed, the tail part of the percussion bit penetrates into the sleeve head 2 through the inner clamping groove 3 at the end part of the sleeve head 2 and penetrates out of the drill rod channel 4 in the installation cylinder 1, and the percussion bit is installed on the percussion bit, so that the connection between the installation sleeve and the percussion bit can be completed;
when the mounting sleeve is used, a hole which is slightly deeper than an expansion screw to be mounted is drilled on a wall body through an impact drill bit, then the function of the impact drill is adjusted to be a hammering function, the mounting sleeve slides forwards, a drill bit of the impact drill bit slides into an inner clamping groove 3 through a drill bit sliding groove 5 and a drill rod channel 4, then a nut of the expansion screw is sleeved in the inner clamping groove 3 at the end part of a sleeve head 2, the impact drill bit is tightly attached to an expansion screw rod to be abutted against the expansion screw rod, then the tail part of the expansion screw is aligned with the hole, the impact drill is started to hammer the expansion screw, after the hammering is mounted in place, the function of the impact drill is adjusted to be an electric hand drill function, the impact drill is started, and the installation of the expansion screw is completed after the screw is tightened;
the central point between the two drill nozzle chutes 5 and the central points of the drill rod channel 4 and the sleeve head 2 are on the same horizontal line, when the electric hammer is used for hammering the expansion screw into the hole, the force output by the impact drill bit always acts on the screw rod central point of the expansion screw due to the clamping effect of the clamping groove 3 in the end part of the sleeve head 2, so that the hammering process is very accurate, stable and smooth, and the situations that the expansion screw is frequently deflected and askew to damage the screw rod when the expansion screw is hammered by a manual hammer can be avoided;
moreover, because the sizes of the two symmetrical drill nozzle sliding grooves 5 are slightly larger than the size of the drill nozzle of the impact drill, the expansion screw can be conveniently installed, when the expansion screw is screwed down by using the electric hand drill function of the impact drill, the rotating force of the impact drill is output through the drill rod of the impact drill, and because the alloy head of the impact drill is clamped in the two symmetrical drill nozzle sliding grooves 5 in a linear structure and forms linkage with the installation sleeve, the rotating force finally acts on the expansion screw, and the nut is screwed down.
The above-mentioned, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
