Description
[technical field]
The utility model relates to a kind of screw, is specifically related to a kind of magnetic-type disassembling prevention screw.
[background technique]
Screw is widely used in the connection of equipment as a kind of screw threads for fastening connecting piece.In the prior art, screw is mostly integrative-structure, screw head is provided with straight groove or cross recess, utilize general flathead screwdriver or cross head driver to be screwed or to dismantle, therefore, adopt the equipment that traditional screw connects easily by the lawless person, to be dismantled, steal or destroy, therefore, at some in particular cases, need to adopt the screw of Anti-dismantling to be fixed equipment.
Chinese utility model patent 201220690606.9 discloses the disassembling prevention screw that a kind of nut can be disconnected, comprise columned screw body, be shaped with outside thread on described screw body, one side of screw body length direction is provided with nut, described nut comprises and twists off piece and contiguous block, one side of described contiguous block is connected with screw body, the side that contiguous block deviates from screw body with twist off piece and be connected, the described external diameter that twists off piece dwindles gradually by twisting off piece to contiguous block direction, the external diameter of described contiguous block is dwindled to twisting off the piece direction gradually by contiguous block, the external diameter smallest end of described contiguous block interconnects with the external diameter smallest end that twists off piece, form the throat that twists off of nut, twist off the side that piece deviates from contiguous block and be provided with mounting groove.This disassembling prevention screw unloads after screw threads proceeds to respective screw hole, can from contiguous block, twist off twisting off piece, make screw lose detachable mounting portion, thereby prevent that screw is disassembled, effectively reduced the loss situation of component in relevant device, safe and reliable, but still have a following defect: 1, design, difficulty of processing are larger, need to meet the intensity that screw screws, consider again the intensity that can be twisted off; 2, to twist off ear end face irregular, not attractive in appearance for screw, also easily by corrosion; 3, the screw head of turning round causes the wasting of resources, if also do not reclaimed, can cause environmental pollution;
Simultaneously, screw is not easy to be affectedly bashful with hand fixing in installation process, and particularly small size screw, do not have hand-held space substantially, to installation, causes very big inconvenience, and screw is easily lost simultaneously.
For above-mentioned defect, be necessary to develop a kind of disassembling prevention screw, after being installed, it is difficult for being disassembled, and design, difficulty of processing are low, and neat appearance and can not cause the wasting of resources and environmental pollution after installing is simultaneously easy for installation, is difficult for losing.
[summary of the invention]
The utility model discloses a kind of magnetic-type disassembling prevention screw, it is difficult for being disassembled after installing, and design, difficulty of processing are low, and neat appearance and can not cause the wasting of resources and environmental pollution after installing is simultaneously easy for installation, is difficult for losing.
The technical solution of the utility model is as follows:
A kind of magnetic-type disassembling prevention screw, the screw body and the screw head that comprise separation, described screw body and screw head adopt magnetic material to make, the end that screw body coordinates with screw head is provided with one section for fastening fastening outside thread, the end that screw head coordinates with screw body is provided with the annulus of the external diameter coupling of internal diameter and screw body, be provided with the fastening internal thread corresponding with fastening outside thread in annulus, fastening internal thread with after fastening outside thread coordinates screw direction and screw body to screw direction identical; The other end of screw head is provided with the opening for screwing.
The screw body of magnetic-type disassembling prevention screw of the present utility model and screw head adopt the mode of fastening outside thread and fastening screw-internal thread fit to transmit clamp load torque, fastening internal thread with after fastening outside thread coordinates screw direction and screw body to screw direction identical, during mounting screw, screw head and screw body are screwed by screw-thread fit, continuation applies to screwing direction the power of screwing, screw head drives the screw body precession, if counterrotating, screw head separates with screw body, thereby prevents that screw is disassembled; Its principle and simple in structure, the transmission of moment is reliable, thereby has reduced the difficulty of design and processing; Its interchangeability is good simultaneously, and minimum of a plurality of screw bodies of same specification need to be equipped with a screw head, install also recyclable recycling of rear screw head, have saved resource, can not cause environmental pollution simultaneously; In addition, screw body rule section invariably after installing, neat appearance; Screw body and screw head adopt magnetic material to make, and during installation, can be adsorbed on instrument, have avoided because of the too small inconvenience that can't be hand-held of screw, easier for installation, and are difficult for losing.
[accompanying drawing explanation]
The decomposition texture schematic diagram that Fig. 1 is the utility model embodiment;
The assembly structure schematic diagram that Fig. 2 is Fig. 1.
[embodiment]
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.
As shown in Figure 1 to Figure 3, magnetic-type disassembling prevention screw of the present utility model, the screw body 1 and the screw head 3 that comprise separation, described screw body 1 and screw head 3 adopt magnetic material to make, the end that screw body 1 coordinates with screw head 3 is provided with one section for fastening fastening outside thread 2, the end that screw head 3 coordinates with screw body 1 is provided with the annulus 5 of the external diameter coupling of internal diameter and screw body 1, be provided with the fastening internal thread 6 corresponding with fastening outside thread 2 in annulus 5, fastening internal thread 6 with after fastening outside thread 2 coordinates screw direction and screw body 1 to screw direction identical, the other end of screw head 3 is provided with the opening 4 for screwing,
The screw body 1 of magnetic-type disassembling prevention screw of the present utility model and screw head 3 adopt fastening outside thread 2 to transmit clamp load torque with the mode that fastening internal thread 6 coordinates, fastening internal thread 6 with after fastening outside thread 2 coordinates screw direction and screw body 1 to screw direction identical, during mounting screw, screw head 3 and screw body 1 are screwed by screw-thread fit, continuation applies to screwing direction the power of screwing, screw head 3 drives screw body 1 precession, if counterrotating, screw head 3 separates with screw body 1, thereby prevents that screw is disassembled; Its principle and simple in structure, the transmission of moment is reliable, thereby has reduced the difficulty of design and processing; Its interchangeability is good simultaneously, and minimum of a plurality of screw bodies 1 of same specification need to be equipped with a screw head 3, install also recyclable recycling of rear screw head 3, have saved resource, can not cause environmental pollution simultaneously; In addition, screw body 1 rule section invariably after installing, neat appearance; Screw body 1 and screw head 3 adopt magnetic material to make, and during installation, can be adsorbed on instrument, have avoided because of the too small inconvenience that can't be hand-held of screw, easier for installation, and are difficult for losing.
