Detailed Description

The present utility model will be specifically described with reference to examples below in order to make the objects and advantages of the present utility model more apparent. It should be understood that the following text is intended to describe only one or more specific embodiments of the utility model and does not limit the scope of the utility model strictly as claimed.

As shown in fig. 1-3, a hard rock layer sampling drill bit comprises a sampling cover 2 and a drill bit 1 vertically arranged inside the sampling cover 2.

Wherein, sampling cover 2 tip is equipped with evenly distributed's latch 201, and the middle part of sampling cover 2 other end is fixed with go-between 202 to install swivel nut 205 at go-between 202 outside screw thread, movable mounting has clamping ring 203 between swivel nut 205 and the go-between 202.

Further, the positioning ring 103 is fixed outside one end of the adjacent connecting ring 202 of the drill bit 1, the slots 102 penetrating to the end are arranged on two sides of the end of the drill bit 1, the clamping strips 204 are fixed on one side of the pressing ring 203, the clamping strips 204 gradually increase in width from top to bottom, the clamping strips 204 are inserted into the slots 102, and the width of one end of the clamping strips 204 adjacent to the pressing ring 203 is larger than the depth of the slots 102.

Further, the inner side of the connecting ring 202 is engaged with the outer side of the drill bit 1, one end of the threaded sleeve 205, which is away from the connecting ring 202, is provided with a pressing plate 207, and the inner side of the pressing plate 207 is abutted against one side of the pressing ring 203, which is away from the clamping strip 204.

According to the structure, the working principle is as follows:

when the drill bit 1 and the sampling cover 2 are required to be disassembled, the threaded sleeve 205 is detached from the connecting ring 202, the clamping strip 204 is pulled out from the position between the connecting ring 202 and the slot 102 by pressing between the pressing ring 203 and the connecting ring 202 in a impacting mode, the clamping strip 204 is disassembled, the drill bit 1 is finally taken out from the other end of the sampling cover 2, and the clamping groove 101 is formed in one side of one end of the drill bit 1, which is positioned at the slot 102, and can be used as an independent drill bit 1.

In addition, the drill bit 1 is inserted into the middle parts of the sampling cover 2, the connecting ring 202, the pressing ring 203 and the screw sleeve 205 from the positioning ring 103 to the end part.

During the use, through with swivel nut 205 spiro union on go up connecting ring 202, through the extrusion of clamp plate 207 to the clamping ring 203 outside, peg graft card strip 204 inside slot 102, and constantly peg graft inside connecting ring 202, and connecting ring 202 is equipped with loudspeaker groove 206 that is loudspeaker form towards card strip 204 one side, card strip 204 outside and loudspeaker groove 206 butt, and then, continuously through rotatory swivel nut 205, through the pressurization of clamp plate 207 to clamping ring 203, make card strip 204 interference grafting inside connecting ring 202, through the fit of card strip 204 and loudspeaker groove 206, and combine threaded connection of swivel nut 205 and connecting ring 202, and then realize in the use, after making swivel nut 205 become flexible because of vibrations, cause the instability that drill bit 1 and sampling cover 2 are connected.
