Description
Technical Field
The utility model relates to a metal product field, more specifically says that it relates to a screw of hand-screw formula.
Background
The screw is a tool for fastening the parts of an object step by utilizing the physical and mathematical principles of the inclined circular rotation and friction of the object. The screw is the general expression of fastener, belongs to daily oral language.
Since the screw is usually screwed into the screw hole by means of a screwdriver, the screwdriver is not always carried around, and the problem that the screw cannot be screwed when the screwdriver is not nearby is caused.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model aims to provide a screw of formula is revolved to hand, it has the advantage that can directly revolve tight screw through the hand under the condition of no screwdriver.
In order to achieve the above purpose, the utility model provides a following technical scheme:
the utility model provides a screw of hand-screw formula, includes head and silk pole portion, and the head is kept away from one side of silk pole portion and is seted up a word groove, the opening both sides in word groove all are fixed with the riser, and are adjacent have the interval between the riser.
By adopting the technical scheme, the vertical plate can be directly twisted by hand under the condition without a screwdriver, so that the screw can be screwed into the screw hole; under the condition that the screwdriver exists, the screwdriver can be inserted between the two vertical plates to rotate, and the use of the screwdriver is not influenced.
The utility model discloses further set up to: adjacent the riser is all the protrusion in one side in opposite directions has a plurality of butt pieces, and the butt piece that closes on laminates each other.
Through adopting above-mentioned technical scheme, under the condition that does not set up the butt joint piece, when rotatory riser through the hand, two risers can be because of the atress takes place deformation in opposite directions, and the junction of force effect between riser and head leads to the two junction to break easily this moment. And through setting up the butt piece, the hand is when rotatory riser, and the butt piece that closes on can butt each other, and the riser is difficult to take place to deform, therefore the junction atress of riser and head obtains great reduction, improves the stability between riser and the head.
The utility model discloses further set up to: the butt joint block is located at the bottom of the vertical plate.
Through adopting above-mentioned technical scheme, if the butt piece is located the top of riser, the screwdriver can strut two risers when using the screwdriver, increases the atress of junction between riser and the head easily. And set up the butt piece in the riser bottom, after penetrating the screwdriver, the screwdriver causes the deformation range of riser less, can reduce the atress of junction between riser and the head, improves the stability of the two junction.
The utility model discloses further set up to: and a chamfer used for guiding the screwdriver is arranged at the top of the abutting block.
Through adopting above-mentioned technical scheme, the chamfer can make things convenient for the tip of screwdriver to get into between the adjacent tight piece that supports, makes things convenient for the inserting of screwdriver.
The utility model discloses further set up to: the vertical plate is arc-shaped.
Through adopting above-mentioned technical scheme, semicircular riser does not have edges and corners, can not stab the hand when hand revolves the riser, improves operation security and travelling comfort.
The utility model discloses further set up to: the arc edge of the vertical plate is rounded.
Through adopting above-mentioned technical scheme, the fillet can go the barb, further improves operation security and travelling comfort.
The utility model discloses further set up to: and an anti-skid bulge is arranged on one side of the adjacent vertical plate opposite to the vertical plate.
Through adopting above-mentioned technical scheme, the effect of increase friction power is played to the antiskid arch, stability when improving the rotating riser.
The utility model discloses further set up to: the side of the antiskid lug away from the vertical plate is an arc surface.
Through adopting above-mentioned technical scheme, the antiskid is protruding not to have the edges and corners, improves operation security and travelling comfort.
To sum up, the utility model has the advantages of it is following:
1. by arranging the vertical plate, people can directly screw the screw through the vertical plate without carrying a screwdriver, so that the operation is convenient;
2. by arranging the abutting block, the abutting block can improve the operation stability of the joint of the vertical plate and the head;
3. set up the riser into semi-circular through the setting, semicircular riser does not have edges and corners, can not stab the hand when hand revolves the riser, improves operation security and travelling comfort.
Drawings
Fig. 1 is an overall schematic diagram of the present embodiment.
Reference numerals: 1. a head portion; 2. a wire rod part; 3. a straight slot; 4. a vertical plate; 5. a butting block; 6. and (4) anti-skid bulges.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
A hand-screw type screw, refer to fig. 1, includes circular head 1 and cylindric lead screw portion 2, and head 1 keeps away from one side of lead screw portion 2 and offers the straight groove 3 of crossing the centre of a circle.
The riser 4 is vertically fixed on both sides of the opening of the straight groove 3, and the riser 4 and the head 1 are integrally formed. The vertical plate 4 is arc-shaped, the arc edge of the vertical plate 4 is far away from the head 1, and the arc edge of the vertical plate 4 is chamfered with a round angle. The adjacent vertical plates 4 are spaced, and when a screwdriver is inserted between the adjacent vertical plates 4, the vertical plates 4 can be slightly deformed.
Adjacent riser 4 one side in opposite directions all the protrusion has a plurality of butt joint piece 5, and whole butt joint piece 5 all is located the bottom of riser 4. The abutting blocks 5 are rectangular, and the opposite side walls of the adjacent abutting blocks 5 are mutually attached. A chamfer is formed between the top wall of the abutting block 5 and one side wall of the adjacent abutting block 5 opposite to the top wall, and when the screwdriver is inserted into the adjacent vertical plate 4, the chamfer plays a role in guiding.
A plurality of anti-skid protrusions 6 are protruded on one side, back to back, of the adjacent vertical plate 4, and one side, far away from the vertical plate 4, of each anti-skid protrusion 6 is an arc surface.
The utility model discloses a working process and beneficial effect as follows: under the condition of no screwdriver, the vertical plate 4 is directly twisted by hand so that the screw is screwed into the screw hole; in the case of a screwdriver, the screwdriver is inserted between two vertical plates 4 and rotated.
The above description is only the preferred embodiment of the present invention, and is not intended to limit the present invention, any modification, equivalent replacement, or improvement made within the design concept of the present invention should be included within the protection scope of the present invention.
