Upper diameter of a circle be more than the lower diameter of a circle, the wall that the umbrella shape fixes cover has fold, and the umbrella shape is fixed
Open-type fold annulus is stamped at the top of cover, the umbrella shape, which is fixed, loads umbrella shape drill bit, the top of the umbrella shape drill bit in cover
In the raised rib for the open-type fold annulus described in the insertion of tip having, the umbrella shape drill bit is fixedly connected with drilling rod.
The vacuum lock device of the umbrella shape drill bit, the open-type fold annulus are circumferentially that fold forms, institute
The side bottom bonding magnetic dot of the openend for the open-type fold annulus stated, the opposite side of the openend of the open-type fold annulus
Top is bonded magnetic dot piece, and when the open-type fold annulus closes, the fold is overlapped mutually, the magnetic dot piece is attracted institute
The magnetic dot stated is fixed, and fold is made of U-shaped and inverted U-shaped interconnection.
The vacuum lock device of the umbrella shape drill bit, the interior circular top part fixed vertical connection of the open-type fold annulus
One group of arc-like sheet, magnetic stripe in arc-like sheet bonding, the interior magnetic stripe are attracted outer magnetic stripe, and the outer magnetic stripe is bonded in out
The inside bottom of mouthful axostylus axostyle set, after the drilling rod that opening shaft rod set volume residence is stated, entangles fixation, the umbrella with rubber sleeve
Shape fixes cover, the open-type fold annulus, the opening shaft rod set composition protective case, the protective case is built-in have described in
Umbrella shape drill bit and the drilling rod, the protective case mounted in vacuum packaging plastic sheath in, the vacuum packaging plastic sheath
Connect vacuum packing machine.
Beneficial effect:
It can be good at protecting umbrella shape drill bit 1. the umbrella shape of the present invention fixes cover, the fold that umbrella shape fixes cover can be made to load umbrella shape
The cutting edge of drill bit, it is ensured that cutting edge will not cut vacuum packaging plastic sheath when being vacuum-packed, and packaging safety can be very
Good protection umbrella shape drill bit and vacuum packaging plastic sheath.
The open-type fold annulus of the present invention can be good at protecting the tip of umbrella shape drill bit, it is ensured that the tip of umbrella shape drill bit is not
It is damaged, and vacuum packaging plastic sheath will not be punctured, it is safe to use, effect is good.
The present invention annulus egative film and annular groove link position can in the inner part, can also fix umbrella shape in the outer part
The diameter dimension of cover can be larger, can also be smaller, can pack the umbrella shape drill bit of certain size, easy to use, effect
It is good.
The opening shaft rod set and rubber sleeve of the present invention can either protect drilling rod, additionally it is possible to permanent opening fold annulus, and
This product it is rational in infrastructure, can Reusability, cost is also low, and using effect is very good.
Brief description of the drawings:
Attached drawing 1 is the structure diagram of this product.
Attached drawing 2 is the overall structure diagram of this product.
Attached drawing 3 is the structure diagram of the fold that umbrella shape drill bit and umbrella shape fix cover in attached drawing 1.
Embodiment:
Below in conjunction with the attached drawing of the present invention, the technical solution in the embodiment of the present invention is clearly and completely described.
Embodiment 1:
A kind of vacuum lock device of umbrella shape drill bit, its composition include:Bottom plate 1, the bottom plate are circumferentially provided with annular groove 2,
The cross section of the annular groove is L-shaped, and the planar base surface of the annular groove is circumferentially provided with one group of circle hole groove 3, the circle
Hole slot is bonded magnetic sheet 4, and the magnetic sheet is attracted magnetosphere 5, and the magnetosphere is bonded in the bottom of annulus egative film 6, the annulus
Egative film is fixedly connected with the part that umbrella shape fixes cover(Ribbed portion or concave rib part), under bottom that the umbrella shape fixes cover is
Circle 7, the top that the umbrella shape fixes cover is upper circle 8, and the upper diameter of a circle is more than the lower diameter of a circle, described
The wall that umbrella shape fixes cover has fold 9, and open-type fold annulus 10 is stamped at the top that the umbrella shape fixes cover, and the umbrella shape is consolidated
Load umbrella shape drill bit 11 in fixed cover, the open-type fold annulus is inserted at the tip 12 that the top of the umbrella shape drill bit has
13 in raised rib, the umbrella shape drill bit is fixedly connected with drilling rod 14.
The open-type fold annulus is circumferentially that fold forms, the side of the openend of the open-type fold annulus
Bottom is bonded magnetic dot 15, and magnetic dot piece 16, the opening are bonded at the top of the opposite side of the openend of the open-type fold annulus
When fold annulus closes, the fold is overlapped mutually, the magnetic dot piece is attracted the magnetic dot and fixes, and fold is by U-shaped 17
It is connected with each other and forms with inverted U-shaped 18.
The interior circular top part fixed vertical of the open-type fold annulus connects one group of arc-like sheet 19, arc-like sheet bonding
Interior magnetic stripe 20, the interior magnetic stripe are attracted outer magnetic stripe 21, and the outer magnetic stripe is bonded in the inside bottom of opening shaft rod set 22, institute
After the drilling rod that the opening shaft rod set volume residence stated is stated, fixation is entangled with rubber sleeve 23, the umbrella shape fixes cover, the opening
Fold annulus, opening shaft rod set composition protective case, the protective case is built-in the umbrella shape drill bit and described
Drilling rod, the protective case is in vacuum packaging plastic sheath 24, vacuum packaging plastic sheath connection vacuum packing machine 25.
Vacuum packing machine is produced by Zhi Hui Machinery Co., Ltd.s.
Operation principle:
Bottom plate and annulus egative film are fixed together, pull loose the fold that umbrella shape fixes cover, loads umbrella shape drill bit and drilling rod, compresses pleat
Wrinkle, umbrella shape fixation cover is pressed on umbrella shape drill bit, covers open-type fold annulus, the fold and umbrella shape for making open-type fold annulus are consolidated
Surely the fold covered is mutually inserted together, and in assembling upper shed axostylus axostyle set, blend rubber set entangles fixation, is then charged into vacuum packet
In dress plastic sheath, encapsulated again with vacuum packing machine.
