The utility model content:
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of quick urgent device of studs that can load and unload and can automatically terminate self-locking fast to studs when withdrawing from is provided.
The quick urgent device of a kind of studs that provides according to the utility model, sleeve, steel ball, lock-screw and the latch segment formed by nut and screw rod, have from top to bottom on the sleeve and be interconnected and all coaxial upper screwed hole and following screwed hole with sleeve, latch segment is installed in sleeve upper end and coaxial with it setting, the screw rod end passes latch segment and upper screwed hole is spirally connected, and steel ball places in the upper screwed hole between the terminal and following screwed hole of screw rod.
The utility model also has following attached technical characterictic:
Be extended with two symmetrically arranged block arcs downwards around described screw rod on the described latch segment lower surface, have the arc groove that cooperates with block arc on the described sleeve periphery wall, wherein, the arc groove width is greater than the width of block arc, makes between block arc after the cooperation and the arc groove and form a gap on its width.
Described latch segment is fixed on the screw rod by set bolt, and can be with screw rod at locking bit with unclamp between the position and rotate, the size of its rotational angle is by the size decision in described gap, wherein, when turning to locking bit, screw rod is in the next, a sidewall of arc groove is replaced on one sidewall of described block arc and the described sleeve, turn to when unclamping, screw rod is in upper, and another sidewall of arc groove is replaced on another sidewall of described block arc and the described sleeve.
The quick urgent device of a kind of studs that provides according to the utility model with respect to the advantage of prior art is:
First, this structure is behind urgent studs, latch segment is in locking bit, screw rod is in the next, its terminal non-set terminal with studs is replaced the top and bottom of steel ball respectively, the following screwed hole of the non-set terminal of studs and sleeve forms self-locking, when withdrawing from, first counter-rotating screw rod, latch segment rotate to thereupon and unclamp the position, screw rod is in upper, at this moment, screw rod end, break away between the non-set terminal of steel ball and studs to support and decide the self-locking and automatic releasing between the non-set terminal of studs and the following screwed hole of sleeve, can withdraw from very easily, and urgent studs can not done pine;
The second, the nut in this structure on the lock-screw can cooperate with pneumatic gun, is undertaken urgently and withdraw from by pneumatic gun, and it loads and unloads very fast, effectively raises production efficiency, has reduced working strength of workers.
Description of drawings:
Introduce the utility model in detail below in conjunction with the drawings and specific embodiments.
Structural representation when Fig. 1 is in locking bit for screw rod in the utility model and latch segment;
Fig. 2 is the main TV structure schematic diagram of latch segment in the utility model;
Fig. 3 is the structural representation of looking up of latch segment in the utility model;
Fig. 4 is the plan structure schematic diagram of the utility model middle sleeve;
Fig. 5 is the main TV structure schematic diagram of the utility model middle sleeve.
The specific embodiment:
Referring to figs. 1 through Fig. 5, the quick urgent device of a kind of studs that provides according to the utility model, comprise sleeve 1, steel ball 2, lock-screw 3 and the latch segment 4 formed by nut 31 and screw rod 32, nut 31 is used for cooperating with pneumatic gun, have from top to bottom on the sleeve 1 and be interconnected and all coaxial upper screwed hole 11 and following screwed hole 12 with sleeve 1, following screwed hole 12 is spirally connected with the non-set terminal of studs, latch segment 4 is installed in sleeve 1 upper end and coaxial with it setting, the through hole 9 that screw rod 32 ends pass on the latch segment 4 is spirally connected with upper screwed hole 11, steel ball 2 places in the upper screwed hole 11 between the terminal and following screwed hole 12 of screw rod 32, be extended with two symmetrically arranged block arcs 41 downwards around screw rod 32 on latch segment 4 lower surfaces, have two arc grooves 13 that cooperate with two block arcs 41 respectively on sleeve 1 periphery wall, wherein, arc groove 13 width are greater than the width of block arc 41, make between block arc 41 after the cooperation and the arc groove 13 and on its width, form a gap 5, latch segment 4 is fixed on the screw rod 32 by set bolt 6, and can be with screw rod 32 at locking bit with unclamp between the position and rotate, the size of rotational angle is by the size decision in described gap 5.
As mentioned above, during this urgent device busy, set terminal with studs screws in the screwed hole to be assembled earlier, general five circles that screw in get final product, then screwed hole 12 5 circles under the non-set terminal screw-in of studs are got final product, subsequently, pneumatic gun is cooperated with nut 31, just changeing the startup pneumatic gun, nut 31, screw rod 32 and latch segment 4 are just going to locking bit thereupon, at this moment, screw rod 32 is in the next, and its end is replaced with steel ball 2 upper ends, and a sidewall of arc groove 13 is replaced on a sidewall of block arc 41 and the sleeve 1, and drive sleeve 1 rotates thereupon, following screwed hole 12 is deepened with the threaded engagement of studs, replaces and form self-locking up to the non-set terminal and steel ball 2 lower ends of studs, at this moment, sleeve 1 can drive the studs rotation, and then screws in studs in the screwed hole to be assembled fast; When withdrawing from, counter-rotating starts pneumatic gun, nut 31, screw rod 32 and latch segment 4 are inverted to thereupon and unclamp the position, at this moment, screw rod 32 is in upper, its terminal disengaging is replaced with steel ball 2 upper ends, simultaneously, steel ball 2 lower ends also break away from and the replacing of studs, the self-locking and automatic releasing between studs and the following screwed hole 12, and another sidewall of arc groove 13 is replaced on another sidewall of block arc 41 and the sleeve 1, and drive sleeve 1 counter-rotating, because of self-locking is removed, sleeve about in the of 1 screwed hole 12 can break away from threaded engagement with studs easily, and do not influence the fiting effect of studs and screwed hole to be assembled.
