Description
Technical field
The utility model relates to machanical fastener field, is specifically related to a kind of adjusting screw.
Background technique
Screw is a kind of common fastening piece, can play the effect of connection according to the structural feature of himself well.Screw utilizes the inclined-plane circular rotating of object and the physics of frictional force and mathematical principle, the by easy stages instrument of fastening implements parts, and screw is industrial necessity indispensable in daily life: the minimum screw used as glasses, clock and watch, electronics etc.; The general screw that TV, musical instrument, household etc. use; Traffic tool, aircraft, electric car, automobile light then sized by screw using.
Adjusting screw comprises screw body and the screw head of one mostly, screw body comprises thread section and smooth section, and smooth section is arranged near screw head, and in order to improve the installation tightness of screw, to prevent loosening of screw, smooth section can be provided with an annular spring leaf.But, annular spring leaf sheathed in existing adjusting screw is directly enclosed within the main body of land mostly, annular spring leaf is near screw head, and between annular spring leaf and thread section without hindrance, in the processes such as transport, installation, annular spring leaf easily slides into thread section, cause annular spring leaf to be stuck on the screw thread of thread section, bring great inconvenience to user.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of adjusting screw, this adjusting screw structure is more reasonable, the tightness of not only installing is good, can be good at preventing the annular spring leaf in screw body from moving down the phenomenon being stuck in thread section simultaneously, and usability is better.
In order to solve the problem existing for background technique, the utility model have employed following technological scheme: a kind of adjusting screw, comprise screw body and the screw head of integrative-structure, described screw body comprises thread section and smooth section, described smooth section arranges near screw head and smooth section is arranged with an annular spring leaf, the smooth section of described screw body is provided with ring cutting groove near one end of screw head, described annular spring leaf is sheathed on the ring cutting groove of smooth section, the outward edge of described annular spring leaf is provided with the bound edge upwards turned down, described bound edge is coated on the bottom margin of screw head, arch upward downwards and contact at the bottom of ring cutting groove in the middle part of described annular spring leaf.
By adopting technique scheme, after screw is screwed into fixture, the position of arching upward in the middle part of annular spring leaf will by top flat and directly and fixture conflict, the pretightening force that screw is installed can be improved, to play good fastening effect, screw loosening can be avoided, and annular spring leaf is coated on screw head bottom margin by bound edge and arch upward in the middle part of it and contact at ring cutting bottom land end, can be good at avoiding in the process of transport, installation, occur that downslide is stuck in the phenomenon of thread section, greatly improve the usability of screw.
Further setting of the present utility model: the top end face of described screw head is provided with regular hexagon groove, the bottom center of described regular hexagon groove is provided with cross recess.
By adopting technique scheme, thus substantially increasing the applicability of screw, in the process screwing screw, hexagon wrench or bottle opener can be selected as required to operate, make the dismounting of screw more convenient.
Further setting of the present utility model: the outer diameter of the smooth section of described screw body is identical with the external thread diameter size of thread section.
By adopting technique scheme, thus the contact of screw body and fixture can be made more abundant, the fastening effect of screw can be improved further.
Further setting of the present utility model: the bottom of the smooth section of described screw body is extended fine stern.
By adopting technique scheme, the setting of fine stern can provide benchmark for screw body is screwed into fixture, and to play the effect of location, turning of simultaneously screw body can being made to start is more light, facilitates operated by personnel.
Further setting of the present utility model: the outer surface of described screw body and screw head is coated with the color zinc layers of one deck trivalent chromium.
By adopting technique scheme, thus be conducive to the intensity improving whole screw, chemical stability is also better, is not easily corroded, simultaneously favourable reduction friction factor, to reduce screw wearing and tearing in use.
The beneficial effects of the utility model are: adjusting screw structure of the present utility model is more reasonable, the tightness of not only installing is good, can avoid loosening phenomenon, can be good at preventing the annular spring leaf in screw body from moving down the phenomenon being stuck in thread section, usability is better simultaneously.
Accompanying drawing explanation
Fig. 1 is the sectional structure schematic diagram of a kind of adjusting screw of the present utility model.
Embodiment
In order to make content of the present utility model more clear, below in conjunction with embodiment, the utility model is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of adjusting screw of the utility model embodiment, comprise screw body 1 and the screw head 2 of integrative-structure, screw body 1 comprises thread section 11 and smooth section 12, smooth section 12 arranges near screw head 2 and smooth section 12 is arranged with an annular spring leaf 3, further, in the smooth section 12 of screw body 1, one end of screw head 2 is provided with ring cutting groove 121, annular spring leaf 3 is sheathed on the ring cutting groove 121 of smooth section 12, further, the bound edge 31 upwards turned down is provided with at the outward edge of annular spring leaf 3, and bound edge 31 is coated on the bottom margin of screw head 2, and arch upward downwards in the middle part of annular spring leaf 3 and contact at the bottom of ring cutting groove 121, thus after screw is screwed into fixture, the position of arching upward in the middle part of annular spring leaf 3 will by top flat and directly and fixture conflict, the pretightening force that screw is installed can be improved, to play good fastening effect, screw loosening can be avoided, and annular spring leaf 3 is coated on screw head 2 bottom margin by bound edge 31 and arch upward in the middle part of it and contact at ring cutting groove 121 bottom, can be good at avoiding in transport, occurring in the process of installing glides is stuck in the phenomenon of thread section 11, greatly improve the usability of screw.
