Description
Technical field
The utility model relates to link technical field, is specially a kind of accurate Self-locking screw.
Background technique
Screw is generally made up of nut and screw rod, often screw can be used when binding device, important effect born in the industry by screw, general is all adopt more accurate screw than the equipment of higher-end, and the volume of screw is the smaller the better, seem better appearance like this, screw mostly adopt in actual applications screw and bullet pad with the use of, screw loosening can be prevented, special on some vibrations equipment, the non-constant of the general auto-lock function of existing screw, but even if there is the more complicated of auto-lock function structural design, cost of production is high, this also brings puzzlement to user, and some screw only has fixing instrument screw could be turned on, for this reason, we propose a kind of accurate Self-locking screw.
Model utility content
The purpose of this utility model is to provide a kind of accurate Self-locking screw, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technological scheme: a kind of accurate Self-locking screw, comprise nut, contiguous block and screw rod, described nut is fixedly connected with the top of contiguous block, the bottom of described contiguous block is fixedly connected with screw rod, described nut, contiguous block and screw rod are one of the forming design, the surface of described nut is provided with crisscross grooves, described nut, run through in the middle part of the inner chamber of contiguous block and screw rod and connecting rod is installed, the lower end of described connecting rod is provided with plug, block is turned round by rivet and power in the bottom of described connecting rod, the inner chamber of described screw rod is provided with limiting stopper, and limiting stopper is positioned at the lower end of plug, the outer surface of described screw rod is provided with outside thread by tapping mode, the upper end of described screw rod is provided with resilient pad, and resilient pad is positioned at the lower end of contiguous block.
Preferably, the degree of depth of described crisscross grooves is 0.3 centimetre.
Preferably, described power turns round block is two.
Preferably, described nut edge is regular hexagon structure, and described nut surrounded surface is convex structure, is concave shape in the middle part of nut.
Preferably, described contiguous block is truncated cone shape structure, and the end of contiguous block is identical with the front end radial diameter of screw rod.
Preferably, the center line of described nut, contiguous block and screw rod is all on same straight line.
Compared with prior art, the beneficial effects of the utility model are: this accurate Self-locking screw, by at nut, the inner chamber of contiguous block and screw rod runs through installation connecting rod, and the top of connecting rod is fixing is connected with crisscross grooves, can to be rotatably connected bar by crisscross grooves like this, turn round block in the bottom of connecting rod by rivet and power to be connected, connecting rod can be made under the rotation of crisscross grooves to rotate, thus reach self-locking action, by the inner chamber mounting limit block at screw rod, the periphery design of nut is regular hexagon, the middle part of nut is designed to crisscross grooves, when groove wrecks, use spanner also can precession, be easy to use, this accurate Self-locking screw, volume is little, there is auto-lock function, be worthy to be popularized.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model nut structure schematic diagram.
In figure: 1 crisscross grooves, 2 nuts, 3 contiguous blocks, 4 connecting rods, 5 plugs, 6 limiting stoppers, 7 power turn round block, 8 rivets, 9 screw rods, 10 outside threads, 11 resilient pads.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1-2, the utility model provides a kind of technological scheme: a kind of accurate Self-locking screw, comprise nut 2, contiguous block 3 and screw rod 9, described nut 2 is fixedly connected with the top of contiguous block 3, the bottom of contiguous block 3 is fixedly connected with screw rod 9, nut 2, contiguous block 3 and screw rod 9 are one of the forming design, the surface of nut 2 is provided with crisscross grooves 1, nut 2, run through in the middle part of the inner chamber of contiguous block 3 and screw rod 9 and connecting rod 4 is installed, and the top of connecting rod 4 is fixing is connected with cross ditch 1 groove, can to be rotatably connected bar 4 by crisscross grooves 1 like this, the lower end of connecting rod 4 is provided with plug 5, block 7 is turned round by rivet 8 and power in the bottom of connecting rod 4, power turns round block 7 can self-locking under the rotation of connecting rod 4, the inner chamber of screw rod 9 is provided with limiting stopper 6, prevent from connecting rod being rotated through dark and causing breakage phenomenon, and a fixing position can be limited, and limiting stopper 6 is positioned at the lower end of plug 5, the outer surface of screw rod 9 is provided with outside thread 1 by tapping mode, the upper end of screw rod 9 is provided with resilient pad 11, the design of resilient pad 11 can make screw fastening shape stronger, avoid sliding phenomenon, and resilient pad 11 is positioned at the lower end of contiguous block 3, the degree of depth of crisscross grooves 1 is 0.3 centimetre, it is two that power turns round block 7, nut 2 edge is regular hexagon structure, when groove wrecks, use spanner also can precession, be easy to use, nut 2 surrounded surface is convex structure, it is concave shape in the middle part of nut 2, contiguous block 3 is truncated cone shape structure, the end of contiguous block 3 is identical with the front end radial diameter of screw rod 9, nut 2, the center line of contiguous block 3 and screw rod 9 is all on same straight line, when stubborn screw, uniform force, be not easy to be fractureed.
