Description

TECHNICAL FIELD

[0001] The utility model relates to a coring drill bit technical field, concretely to a novel coring drill bit. BACKGROUND

[0002] Coring drill bit, also known as hollow drill bit or hole opener, is a kind of tool specially designed for drilling complete cylindrical sample from solid material such as rock, concrete, wood, metal, this kind of drill bit has wide application in multiple fields, mainly including but not limited to geological exploration, building construction, mineral exploitation and material science research etc.

[0003] At present, when the coring drill bit is in hole opening coring, generally installs the coring drill bit on the hand-held hole turning machine, and lets the worker hold the hole turning machine to take the core to the target, if the sampling surface of the sampling target is relatively smooth and flat, the worker will slip when the drill bit first contacts the sampling target when taking the core, at this time, the worker will first open a slight sampling groove on the coring surface, and then take the core, which also leads to low work efficiency, time-consuming and laborious. SUMMARY

[0004] The utility model discloses a novel coring drill bit, can be limited to support the drill bit body through the setting movement rod, thereby not needing to open the groove to the coring surface, greatly reduce because the problem of low work efficiency caused by slipping.

[0005] To achieve the above object, provide a kind of novel coring drill bit, including drill bit body, the middle end outside of drill bit body is rotatably connected with rotating ring, the surface of rotating ring is equipped with several rotating grooves, the inside of rotating groove is rotatably connected with movement rod, the inside of movement rod is slidably connected with support rod, the end of support rod away from movement rod is fixedly connected with fixed block, the end of movement rod close to fixed block is fixedly sleeved with fixed ring outside, the outside of support rod is sleeved with spring, the both ends of spring are fixedly connected with the side of fixed block and fixed ring close to each other, the upper end outside of drill bit body is rotatably connected with external thread sleeve, the outside of external thread sleeve is threadedly connected with push ring, the lower surface of push ring is rotatably connected with adjusting ring, the outside of adjusting ring is equipped with adjusting groove, the quantity and position of adjusting groove correspond with rotating groove, the inside of adjusting groove is rotatably connected with adjusting rod, the side of adjusting rod away from adjusting groove is equipped with connecting groove, the inside of connecting groove is rotatably connected with the outside of movement rod.In use, rotate, hold external thread sleeve and fix it, and rotate push ring to let push ring, drive adjusting ring to move up and down along the outside of external thread sleeve, rotate under the cooperation of adjusting rod and movement rod, so that the contact position of fixed block and coring point is adjusted, the drill bit body located in the center is limited by several fixed blocks, to reduce the problem of low work efficiency caused by slipping.

[0006] According to the new core drill bit, the lower end of the outer threaded sleeve is fixed outside with a limiting ring, and the area of the limiting ring is smaller than that of the adjusting ring. By setting the limiting ring smaller than the adjusting ring, the problem that the limiting ring blocks the adjusting ring and affects the adjustment of the adjusting ring is reduced.

[0007] According to the new core drill bit, the end of the outer threaded sleeve away from the limiting ring is fixed outside with a connecting ring, and the connecting ring is made of rubber. By setting the connecting ring made of rubber, the friction force of the worker during use is increased, the worker can more stably fix the outer threaded sleeve during adjustment, and then adjust.

[0008] According to the new core drill bit, the outer sides of the connecting ring and the pushing ring are provided with anti-skid stripes, and the anti-skid stripes are arranged in a plurality of and uniformly distributed. By setting a plurality of anti-skid stripes, the friction force of the worker during use is increased, and the adjustment is more stable.

[0009] According to the new core drill bit, the adjusting ring is arranged outside the drill bit body, and the inner side of the adjusting ring is not in threaded contact with the outer side of the outer threaded sleeve. By setting the inner side of the adjusting ring and the outer side of the outer threaded sleeve not in threaded contact, the adjusting ring is prevented from being blocked by the thread during adjustment and movement, and the movement is more stable.

[0010] According to the new core drill bit, the outer side of the moving rod is in contact with the surface of the connecting groove, and the contact surfaces of the moving rod and the connecting groove are smooth. By setting the contact surfaces of the moving rod and the connecting groove to be smooth, the friction is reduced to make the moving rod move more stably in the connecting groove.

[0011] According to the new core drill bit, the contact surfaces of the supporting rod and the moving rod are smooth, and the fixed block is made of rubber. By setting the fixed block made of rubber, the friction of the fixed block is increased when supporting and positioning, and the support is more stable.

[0012] According to the new core drill bit, the surfaces of the adjusting groove and the rotating groove are smooth, and the position of the adjusting groove away from the drill bit body is greater than the position of the rotating groove away from the drill bit body. By setting the surfaces of the adjusting groove and the rotating groove to be smooth, the friction is reduced, and the components inside the adjusting groove and the rotating groove move more stably.

[0013] The utility model discloses an advantageous effect: through the mutual cooperation of fixed block, push ring and outer thread sleeve, can rotate push ring when the user uses, let push ring drive adjusting ring go up and down along the outside of outer thread sleeve, under the cooperation of adjusting rod and the rotation of moving rod, thereby the contact position of fixed block and the core taking point is adjusted, and the fixed block is limited to the drill bit body, and then does not need to groove the core taking surface first, greatly reduces the problem of the reduction of work efficiency because of the slippage, saves time and energy.

[0014] The additional aspects and advantages of the utility model will be partly given in the following description, and some will become obvious from the following description or be understood through the practice of the utility model. BRIEF DESCRIPTION OF DRAWINGS
