Description

Anti-dismantling securing member

Technical field

This utility model is related to a kind of securing member, particularly a kind of Anti-dismantling securing member.

Background technology

Securing member is indispensable necessary during we live, for flexibly fixing two objects, currently used Securing member is dismountable type, freely can dismantle between bolts and nuts, but some Code in Hazardous Special Locations need to install nut After be permanently affixed on bolt or greatly increase dismounting difficulty come prevent dismounting to increase antitheft, loss prevention function.

Utility model content

In order to solve the problems, such as prior art, this utility model provides a kind of Anti-dismantling securing member, and the Anti-dismantling is tight Firmware is that groove is provided with bolt, and latch is arranged on nut, and latch is snapped in groove, so as to limit bolts and nuts Relative rotation, so as to reach Anti-dismantling, antitheft, anti-lost purpose.

This utility model is adopted the following technical scheme that：Anti-dismantling securing member, including screw bolt and nut, have at least on bolt One groove along its length, is provided with nut for accommodating the cavity of latch, width and the recess width phase of cavity Together, cavity bottom is communicated with the screwed hole of nut, has through hole to run through at the top of cavity and nut outer wall between, and lock is provided with cavity Stops, the vertical height of latch are more than the depth of groove less than the depth of cavity.

Anti-dismantling securing member of the present utility model when in use, nut is screwed on bolt, nut almost in place when, slowly Rotating nut, makes the cavity on nut corresponding with the groove on bolt（The through hole of nut outer wall is located just at groove center line On）, then to be inserted in through hole with a pole, the bottom of pole is against on latch, enforces latch, makes latch bottom Portion is contacted with bottom portion of groove, and as the height of latch is more than the depth of groove, now the top of latch is still located in cavity, So as to limit the relative rotation of bolts and nuts, the purpose of Anti-dismantling is played.

As one embodiment of the present utility model, latch and cavity interior walls interference fits.Latch is stuck in cavity, Only when with latch is pushed hard in pole insertion through hole, latch could slide in groove along cavity interior walls, so as to limit The relative rotation of bolts and nuts processed.

Used as another embodiment of the present utility model, latch is by magnetic absorption in cavity.Latch is inhaled by magnetic force It is attached in cavity, only when with latch is pushed hard in rod insertion through hole, latch can just overcome magnetic attraction, into recessed Groove, and adsorb in bottom portion of groove, so as to limit the relative rotation of bolts and nuts.

As one embodiment of the present utility model, screwed hole is provided with latch, on described screwed hole and nut Lead to the hole site is corresponding, and the diameter of screwed hole is less than the diameter of through hole.When latch is pushed in groove, one still can be only used In root pole insertion through hole, if pole is with diameter greater than screw thread bore dia, pole bottom is against on latch top surface and promotes locking Block, if pole diameter is less than screw thread bore dia, pole bottom is against screwed hole bottom and promotes latch, in a word, can be by Latch is shifted onto in groove；When locking is released, then need to be threaded in hole with the screw matched with screwed hole, Ran Houxiang Upper lifting latch, makes latch depart from from groove, it is possible to by nut and Bolt dismantling.

Specific embodiment

Below in conjunction with the accompanying drawings embodiment of the present utility model is described specifically：

Embodiment one

Anti-dismantling securing member, as shown in Fig. 1-Fig. 3, including bolt 10 and nut 20, with one along its length on bolt 10 The groove 11 in degree direction, is provided with nut 20 for accommodating the cavity 22 of latch 30, width and 11 width of groove of cavity 22 Identical, 22 bottom of cavity is communicated with the screwed hole of nut 20, has through hole 21 to run through at the top of cavity 22 and 20 outer wall of nut between, recessed Latch 30 is provided with chamber 22, latch 30 is coordinated with 22 internal wall transitions of cavity, the vertical height of latch 30 is less than cavity 22 depth and be more than the depth of groove 11.

During use, make the groove 11 of bolt 10 relative with 22 position of cavity of nut 20, through hole 21 is inserted with a pole In, pole bottom is against on latch 30, and latch 30 is shifted onto in groove 11, as the vertical height of latch 30 is more than recessed The depth of groove 11, so when 30 bottom of latch is against 11 bottom of groove, still some is located in cavity 22, so as to limit Bolt 10 and the relative motion of nut 20, play the purpose of Anti-dismantling.

Embodiment two

Anti-dismantling securing member, as shown in Figure 1, Figure 4 and Figure 5, including the material of bolt 10 and nut 20, bolt 10 and nut 20 Material is all ferrum, has four grooves 11 along its length, be provided with for accommodating latch 30 in nut 20 on bolt 10 Cavity 22, the width of cavity 22 are identical with 11 width of groove, and 22 bottom of cavity is communicated with the screwed hole of nut 20, at the top of cavity 22 Between 20 outer wall of nut there is through hole 21 to run through, in cavity 22, be provided with latch 30, the material of latch 30 is Magnet, locking Block 30 adsorbs in cavity 22, and the vertical height of latch 30 is more than the depth of groove 11 less than the depth of cavity 22, locking 30 upper surface of block also has screwed hole 31, and screwed hole 31 is corresponding with 21 position of through hole, and the diameter of screwed hole 31 is less than through hole 21 Diameter.

During use, make the groove 11 of bolt 10 relative with 22 position of cavity of nut 20, it is screwed with a root bottom part Bolt special is through in the insertion screwed hole 31 of through hole 21, and coordinates with 31 screw thread of screwed hole, and latch 30 is shifted onto in groove 11, As the vertical height of latch 30 is more than the depth of groove 11, so when 30 bottom of latch is against 11 bottom of groove, still Some is located in cavity 22, so as to limit the relative motion of bolt 10 and nut 20, plays the purpose of Anti-dismantling；Need solution Make except restriction is rotated, lift screw rod upwards, as screw rod is threadedly coupled with latch 30, latch 30 is moved also with screw rod, Until latch 30 thoroughly leaves groove 11, now, bolt 10 and nut 20 can be relatively rotated again, such that it is able to by nut 20 Separate with the dismounting of bolt 10, but, due to needing to use special screw rod, do not have the people of bolt special complete dismounting, because This, can also play Anti-dismantling and antitheft purpose.

Specific embodiment of the present utility model is the foregoing is only, is not limitation of the utility model, every utilization The equivalent transformation made by mentality of designing of the present utility model and principle, or directly or indirectly it is used in other related technology necks Domain, is included in scope of patent protection of the present utility model in the same manner.
