Abstract
The utility model relates to a fastener, in particular to from locking screw. The utility model provides a following technical scheme: a stopper that from locking screw, the screw rod of being connected including the spiral shell head and with the spiral shell head is equipped with the screw thread on, the junction of spiral shell head and screw rod be equipped with with the first physically locking dish of setting of spiral shell, this locking dish equipartition on the terminal surface of screw rod has a mutual linking offered spacing locking groove on the outer peripheral face of screw rod, this spacing locking inslot is equipped with the locating part that can follow spacing locking groove and move. Adopt above -mentioned technical scheme, provided an antiskid, connected the from locking screw who fastens.
Description
Technical field
The utility model relates to a kind of securing member, particularly a kind of self-locking screw.
Background technology
Screw is the securing member for mounting article, and its utilization is comparatively extensive, conventionally screw is mounted to fixation and is connected with fixture in the screw of object, just can implement to fix. Between screw and screw, spin by screw thread; but screw often can, because external factor exits in by screw, cause fixation to can not get fixing completely after being mounted in screw; while being used for comparatively special occasion, even can there is larger potential safety hazard.
Summary of the invention
The deficiency existing for prior art, the utility model provide a kind of anti-skidding, connect fastening self-locking screw.
For achieving the above object, the utility model provides following technical scheme: a kind of self-locking screw, the screw rod that includes spiral shell head and be connected with spiral shell head, screw rod is provided with screw thread, it is characterized in that: described spiral shell head and the junction of screw rod are provided with the locking plate being wholely set with spiral shell head, this locking plate is evenly equipped with the limited block of mutual linking on the end face of screw rod, offers limiting locking groove on the outer peripheral face of described screw rod, is provided with the locating part that can move along limiting locking groove in this limiting locking groove.
Adopt technique scheme, by locking plate being set on spiral shell head, can make this screw in when locking without cushion is set, and this locking plate and spiral shell head are wholely set, and in locking process, locking plate can not be subjected to displacement, and its locking effect is good, impel the screw can be because external force is by getting loose in screw, the setting of screw rod upper limit locking slot and locating part can further prevent that screw rod from, by getting loose in screw, having improved skidproof effect, makes screw more fastening with being connected of object.
The utility model is further set to: limiting locking groove is around the outer peripheral face setting of screw rod, and one end of limiting locking groove is large end, the other end is small end, greatly end with small end between for dwindling gradually shape setting, described locating part is the spacing steel ball of being located in limiting locking groove.
Adopt technique scheme, arrange so simple in structure, easy to process.
The utility model is further set to: the limited block on locking plate is dentate body.
Adopt technique scheme, locking effect is set so better.
Below in conjunction with accompanying drawing, the utility model is further described.
Brief description of the drawings
Fig. 1 is the schematic perspective view of the utility model embodiment.
Detailed description of the invention
A kind of self-locking screw as shown in Figure 1, the screw rod 2 that includes spiral shell head 1 and be connected with spiral shell head 1, screw rod 2 is provided with screw thread 21, spiral shell head 1 is provided with the junction of screw rod 2 locking plate 3 being wholely set with spiral shell head 1, this locking plate 3 is evenly equipped with the limited block 31 of mutual linking on the end face of screw rod 2, on the outer peripheral face of screw rod 2, offer limiting locking groove 22, in this limiting locking groove 22, be provided with the locating part 23 that can move along limiting locking 22 grooves. In such scheme, by locking plate 3 is set on spiral shell head 1, can make this screw in when locking without cushion is set, and this locking plate 3 is wholely set with spiral shell head 1, and in locking process, locking plate 3 can not be subjected to displacement, and its locking effect is good, impel the screw can be because external force is by getting loose in screw, the setting of screw rod 2 upper limit locking slots 22 and locating part 23 can further prevent that screw rod 2 from, by getting loose in screw, having improved skidproof effect, makes screw more fastening with being connected of object.
In the utility model embodiment, limiting locking groove 22 is around the outer peripheral face setting of screw rod 2, and one end of limiting locking groove 22 is large end, and the other end is small end, between large end and small end, for dwindling gradually shape setting, locating part 23 is for being located at the spacing steel ball in limiting locking groove 22. In use, when screw rod 2 is inserted in screw, steel ball is moved towards small end by the large end of limiting locking groove 22, move to after small end can clamping stagnation between screw rod 2 and screw, make to obtain between screw rod 2 and screw spacing.
In order further to improve locking effect, the limited block 31 on locking plate 3 is dentate body.
