Abstract
The utility model relates to a theftproof screw nut for a screw bolt. The utility model is characterized in that the front end of a thread sleeve is fixed with a cushion ring, the cushion ring is provided with a directional clamping groove which is matched with the directional protrusion which is sheathed on the front end surface of an outer sleeve of the thread sleeve, when the only outer sleeve rotates on the positive direction, the thread sleeve can be driven to screw in by the cushion ring on the screw bolt, and the fastening purpose is achieved. When the outer sleeve rotates on the reversing rotation, the directional protrusion can disengage from the directional clamping groove, and thereby, the outer sleeve runs idle, the thread sleeve can not be loosened, and thereby, the purpose of preventing non-working dismounting can be achieved, and the protective properties of engineering equipment and facilities are enhanced.
Description
The utility model belongs to the mechanical connection securing means, and particularly a kind of energy is prevented inoperative demounting bolt anti-theft nut, and its mechanical connection fastening piece that can be used as engineering equipment, facility uses, to improve barrier propterty.
Development along with China's modernization construction, open-air open-air work equipment and various facility are increasing, for example: expressway protects and blocks, electric power conveying equipment, field irrigation equipment etc., these equipment and facility one side day and night someone are nursed, and on the other hand, the fixing General fasteners of mostly having adopted again of its mechanical connection, with general tool such as spanner, pipe wrench get final product conveniently fast disassembling, protective is poor, therefore, stolen phenomenon happens occasionally, and what have also causes great economic loss and social influence.
The purpose of this utility model provides a kind of bolted anti-theft nut that is used for, and its existing general nut is convenient to fastening effect, and the function that prevents the inoperative dismounting is arranged again, can improve the safety protection performance of engineering equipment, facility effectively.
The purpose of this utility model is achieved by the following technical solution.
The utility model mainly is made of swivel nut, packing ring, overcoat.A cylindrical swivel nut that matches with bolt, its front end is installing a packing ring, and this packing ring is provided with directed draw-in groove, and the swivel nut tail end is provided with flange.Suit an overcoat on the swivel nut, and this overcoat external form is identical with standard universal nut external form, and its front-end face is provided with orientation projection, corresponding the matching of directed draw-in groove on this orientation projection and the packing ring.
When utilizing the general utility tool forward to turn overcoat, orientation projection sticks in the directed draw-in groove, rotates precession thereby drive swivel nut by packing ring on bolt, and parts are tightened up.If oppositely turn overcoat, at this moment, orientation projection will be deviate from directed draw-in groove and be skidded, and dally even be enclosed within on the swivel nut outward, and can not make swivel nut loosening, prevent the inoperative dismounting with this, reach certain safeguard function, avoid the engineering equipment facility stolen.If owing to need of work is dismantled, utilize special special tool to make things convenient for fast and finish.
Compared with the prior art, the utlity model has following significant advantage: simple in structure, processing and use are all very convenient, can effectively play antitheft effect, and protection engineering and facility are not subjected to artificial destruction and loss.
Now in conjunction with the accompanying drawings and embodiments the utility model is done an explanation.
Fig. 1 is the utility model sectional view;
Fig. 2 is that the A-A of Fig. 1 is to view;
Among the figure: 1-bolt; 2-overcoat; 3-swivel nut; 4-packing ring; 5-pin; 6-directed draw-in groove; 7-orientation projection; 8-flange; 9-chute.
As shown in Figure 1, the fastening anti-theft nut of bolt 1 mainly is made of overcoat 2, swivel nut 3, packing ring 4.
Bolt 1 adopts the standard universal spiral shell complete, and as hexagon head or cup head, its diameter of thread is generally M14～M24.
The swivel nut 3 that matches with bolt 1 is a cylindrical body, and its front end step place is installing packing ring 4, and the two is fixing with two pins 5 of symmetrical position during assembling, and its tail end is provided with flange 8, comes off to prevent overcoat 2.Be symmetrically arranged with two directed draw-in grooves 6 (consulting shown in Figure 2) on the packing ring 4.Overcoat 2 is sleeved on the swivel nut 3, its external form adopts standard universal nut external form as four jiaos, hexagonal, be symmetrically arranged with two orientation projection 7 that match with directed draw-in groove on the front-end face of this overcoat 2, the two cooperation makes that swivel nut can only the forward precession, to reach fastening purpose, one section chute 9 is arranged in the overcoat 2, make it can on swivel nut, move, rotate and can not deviate from by flange 8 effect.When the counterrotating overcoat, orientation projection 7 is deviate from directed draw-in groove 6 and is skidded, thereby makes swivel nut 3 can not become flexible.
The utility model is when implementing, and each part material and manufacturing process are identical with the material and the manufacturing process thereof of standard fasteners.
