Description
Technical field
The utility model relates to technical field of fastening, is specifically related to a kind of novel holding down bolt.
Background technique
At present, existing holding down bolt is made up of head and screw rod (with externally threaded cylindrical body) two-part, needs and nut screw connection, for being fastenedly connected two parts with through hole.This Connecting format claims bolt to connect.As nut is screwed off from bolt, can make again these two parts separately, therefore bolt connection belongs to removably connect.Existing holding down bolt structural design is unreasonable, function singleness, can only fix two parts with through hole, and can not be connected with other parts and locate, and existing holding down bolt easily loosens after connecting, and resistance to shock is poor.
Summary of the invention
For the deficiency that prior art exists, it is good that the purpose of this utility model is to provide a kind of reasonable in design, resistance to shock, not only can connect two parts with through hole, and externally can play the novel holding down bolt of positioning action by relay part.
For achieving the above object, the utility model provides following technological scheme: a kind of novel holding down bolt, comprise screw rod and screw head, described screw rod and screw head left end are wholely set, described screw rod left end is provided with annular groove, be socketed with rubber loose-proof sleeve in described annular groove, and this rubber loose-proof sleeve outer wall has been wholely set several spacing preiections, described screw head left side is wholely set several locking projections, described screw rod right-hand member is provided with glove hole, and described glove hole built-in type is provided with magnet, described screw head right side has been wholely set reinforced block, described reinforced block right side is provided with the first tapped hole, this the first tapped hole internal thread is connected with positioning rod, positioning rod deviates from reinforced block end and is provided with locating notch, locating notch deviates from reinforced block end and has been wholely set contiguous block, described contiguous block is provided with locking device, described locking device comprises lock screw and latch, described contiguous block is provided with the second tapped hole, the centerline parallel of described second tapped hole and the first tapped hole, described lock screw head is threaded with latch towards a left side through after the second tapped hole, by regulating lock screw, latch is moved left and right.
By adopting technique scheme, after screw rod being arranged rubber loose-proof sleeve, the thread groove clamping of the spacing preiection on rubber loose-proof sleeve and existing tapped hole, plays position-limiting action, makes bolt resistance to shock good; And the design of positioning rod, existing external parts can be located, locking device structure is simple, easy to use, can be locked to the existing external parts being positioned at locating notch, connect reliable, reasonable in design, resistance to shock are good, not only can connect two parts with through hole, and externally can play positioning action by relay part, function is many, applied widely.
The utility model is set to further: described reinforced block is symmetrically arranged with two threading holes.By this setting, threading hole arranges rationally, and can connect existing in threading hole is locking rope, and by bolt and neighbouring being bolted together, anti-loosening property is good.
The utility model is also set to further: the locking projection structure triangular in shape described in several.By this setting, locking projection is arranged rationally, and anti-loosening property is better.
The utility model is also set to further: described first tapped hole overlaps with the center line of screw rod.By this setting, the first tapped hole position arranges rationally, and positioning rod connects convenient.
The utility model is also set to further: described positioning rod is made by stainless steel material.By this setting, positioning rod not easily gets rusty, and mounting or dismounting are convenient.
The utility model has the advantages that: compared with prior art, the utility model vibrational power flow is reasonable, after screw rod being arranged rubber loose-proof sleeve, the thread groove clamping of the spacing preiection on rubber loose-proof sleeve and existing tapped hole, play position-limiting action, make bolt resistance to shock good: and the design of positioning rod, existing external parts can be located, locking device structure is simple, easy to use, the existing external parts being positioned at locating notch can be locked, connect reliable, reasonable in design, resistance to shock is good, not only can connect two parts with through hole, and externally can play positioning action by relay part, function is many, applied widely.
Below in conjunction with Figure of description and specific embodiment, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
See Fig. 1, a kind of novel holding down bolt disclosed in the utility model, comprise screw rod 1 and screw head 2, described screw rod 1 is wholely set with screw head 2 left end, described screw rod 1 left end is provided with annular groove 11, be socketed with rubber loose-proof sleeve 3 in described annular groove 11, and this rubber loose-proof sleeve 3 outer wall has been wholely set several spacing preiections 31, described screw head 2 left side has been wholely set several locking protruding 21, described screw rod 1 right-hand member is provided with glove hole 22, and described glove hole 22 built-in type is provided with magnet 4, described screw rod 1 head right side has been wholely set reinforced block 23, described reinforced block 23 right side is provided with the first tapped hole 231, this the first tapped hole 231 internal thread is connected with positioning rod 5, positioning rod 5 deviates from reinforced block 23 end and is provided with locating notch 51, locating notch 51 deviates from reinforced block 23 end and has been wholely set contiguous block 52, described contiguous block 52 is provided with locking device, described locking device comprises lock screw 6 and latch 7, described contiguous block 52 is provided with the second tapped hole 521, the centerline parallel of described second tapped hole 521 and the first tapped hole 231, described lock screw 6 head is threaded with latch 7 towards a left side through after the second tapped hole 521, by regulating lock screw 6, latch 7 is moved left and right.
