Abstract
The utility model relates to a screw plug, which comprises a head part and a screw rod, wherein the head part is in a regular hexagon shape, a line which is formed by connecting the diagonal angles of the regular hexagon is used as a first diagonal line, the edge, opposite to the other side of the screw rod, of the head part is provided with two first rectangular grooves, the two first rectangular grooves are symmetrical relative to the first diagonal line, and are also symmetrical relative to the center line of the edge where the first rectangular grooves are arranged, the head part is provided with a second rectangular groove along the first diagonal line, and the second rectangular groove is horizontally arranged in the head part in a through way. Through the technical scheme, the screw plug can be screwed by a plurality of ways.
Description
Technical field
The utility model is specifically related to a kind of plug screw.
Background technique
Plug screw is the part that is threaded connection to stop fluid seepage, because common line size is generally little, and volume plug screw size supporting with it is also smaller and more exquisite, then because the limitation of plug screw size makes in manual operation, screwing of plug screw brought trouble, of today how by spanner, plug screw being screwed, but undersized spanner is uncommon, and directly screw with hand, can cause to screw deficiency, can produce seepage and loosening after working long hours.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of plug screw that can screw in several ways.
for achieving the above object, the utility model provides following technological scheme: comprise head and screw rod, it is characterized in that: described head is set to regular hexagon, the line that described regular hexagon diagonal angle is connected to form is the first diagonal, the edge of the opposite side of the relative screw rod of described head offers two the first rectangular recess relatively, described two the first rectangular recess are symmetrical about the first diagonal, described the first rectangular recess is symmetrical about the center line at the edge at the first rectangular recess place, described head is provided with the second rectangular recess along the first diagonal, described the second rectangular recess level connects the head setting.
By adopting technique scheme, when needs, plug screw is screwed but not very during undersized track wrench, can clamp both sides the first rectangular recess by vice screws it, can provide like this to screw power larger, fastness is installed higher, is perhaps put into the second rectangular recess to screwing by harder tinsel, such mode also can provide the power of screwing, prevent from directly screwing with hand and cause and screw deficiency, can cause seepage and loosening after working long hours.
The utility model further is set to: the length of described the first rectangular recess is 2mm, and the width of described the second rectangular recess is 1.5mm.
By adopting technique scheme, the length of the first rectangular recess is that the such setting of 2mm makes the first rectangular recess can meet the width that general vice has, make screw more laborsaving, the width of the second rectangular recess is that 1.5mm also makes the tinsel that can coordinate be easier to seek, make the mode that can screw more, selectivity is larger.
The utility model further is set to: described head and screw rod are made by 40Cr.
By adopting technique scheme, the 40cr steel has certain toughness, plasticity and wear resistance after heat treatment, is fit to very much the usage requirement of plug screw, and the use of 40Cr steel extensively, is easy to buying and processing, brings very big facility to production.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Description of drawings
Fig. 1 is the side view of the utility model embodiment.
Embodiment
as shown in Figure 1, the utility model discloses a kind of plug screw, comprise head 1 and screw rod 2, head 1 is set to regular hexagon, the line that the regular hexagon diagonal angle is connected to form is the first diagonal 11, the edge of the opposite side of head 1 relative screw rod 2 offers two the first rectangular recess 12 relatively, two the first rectangular recess 12 are symmetrical about the first diagonal 11, the first rectangular recess 12 is symmetrical about the center line at the edge at the first rectangular recess 12 places, head 1 is provided with the second rectangular recess 13 along the first diagonal 11, the second rectangular recess 13 levels connect head 1 and arrange, when needs, plug screw is screwed but not very during undersized track wrench, can clamp both sides the first rectangular recess 12 by vice screws it, can provide like this to screw power larger, fastness is installed higher, perhaps putting into 13 pairs of the second rectangular recess by harder tinsel screws, such mode also can provide the power of screwing, prevent from directly screwing with hand and cause and screw deficiency, can cause seepage and loosening after working long hours.
The length a of the first rectangular recess 12 is 2mm, the width b of the second rectangular recess 13 is 1.5mm, the length a of the first rectangular recess 12 is that the such setting of 2mm makes the first rectangular recess 12 can meet the width that general vice has, make screw more laborsaving, the width b of the second rectangular recess 13 is that 1.5mm also makes the tinsel that can coordinate be easier to seek, make the mode that can screw more, selectivity is larger.
Head 1 and screw rod 2 are made by 40Cr, and the 40cr steel has certain toughness, plasticity and wear resistance after heat treatment, are fit to very much the usage requirement of plug screw, and the use of 40Cr steel extensively, are easy to buying and processing, bring very big facility to production.
