Abstract
The utility model relates to a machine parts technical field especially relates to an auto -lock self -lubricating screw rod. Including the screw rod main part that has the nut, the nut tip of screw rod main part is equipped with along the locking hole of screw rod main part direction, is equipped with the spacing hole that a plurality of link up screw rod main part outer wall and locking hole in the screw rod main part, locks the downthehole locking screw who matches with it that is equipped with, the spacing downthehole latch segment that matches with it that is equipped with. This screw rod not only can be so that ab intra to screw rod dropwise add lubricating oil, can inwards screw locking screw through the locking hole simultaneously to exert pressure to the latch segment, and then to the outside pressure that forms of screw rod main part, avoid the screw rod not hard up.
Description
Technical field
The utility model relates to component of machine technical field, particularly relates to a kind of self-locking selflubricating screw rod.
Background technique
Bolt: mechanical parts, the cylindrical threaded fastening piece of adapted nut.By head and screw rod (with an externally threaded cylindrical body) class fastening piece dimerous, need 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.
The frequency of utilization of bolt is very high, but when using in the early stage, easily causes loosening, causes tightness to be deteriorated, along with the prolongation of time, due to air and contact with moisture, cause screw body and get rusty, cause bolt not easily to loosen.
Summary of the invention
The purpose of this utility model is to solve the problem that current bolt or screw rod initial stage easily loosen, the later stage not easily loosens, providing a kind of self-locking selflubricating screw rod.
In order to reach above-mentioned model utility object, the utility model by the following technical solutions:
A kind of self-locking selflubricating screw rod, comprise the screw body with nut, the nut end of screw body is provided with the locking hole along screw body direction, screw body is provided with the spacing hole of several through screw body outer walls and locking hole, be provided with the lock screw matched with it in locking hole, in spacing hole, be provided with the locking block matched with it.
As preferably, the termination, bottom of described lock screw is wedge shape.
As preferably, the termination that described locking block is positioned at screw body is wedge shape.
As preferably, termination, described lock screw top is provided with the head of a nail.
As preferably, described lock screw is threaded with locking hole.
The utility model compared with prior art, beneficial effect is: lock screw not only so that drip lubricant oil from inside to screw rod, inwardly can be screwed by locking hole by this screw rod simultaneously, thus applies pressure to locking block, and then to the outside mineralization pressure of screw body, avoid screw bolt loosening.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is sectional view of the present utility model.
In figure: 1 screw body, 2 nuts, 3 locking holes, 4 spacing holes, 5 lock screws, 6 locking blocks, 7 heads of a nail.
Embodiment
Below by specific embodiment, explanation is further described to the technical solution of the utility model.
Embodiment:
A kind of self-locking selflubricating screw rod, as depicted in figs. 1 and 2, shown in, comprise the screw body 1 with nut 2, nut 2 end of screw body 1 is provided with the locking hole 3 along screw body 1 direction, screw body 1 is provided with the spacing hole 4 of several through screw body 1 outer walls and locking hole 3, is provided with the lock screw 5 matched with it in locking hole 3, and the termination, bottom of lock screw 5 is wedge shape.Be provided with the locking block 6 matched with it in spacing hole 4, the termination that locking block 6 is positioned at screw body 1 is wedge shape.
Lock screw 5 is threaded with locking hole 3, and termination, lock screw 5 top is provided with the head of a nail 7 simultaneously.The head of a nail 7 has for lock screw 5 is screwed or loosen in hexagonal structure, word structure or a cross structure.
As shown in Figure 2, this structure not only can carry out selflubricating to screw rod self to outward appearance, locks simultaneously, prevent screw bolt loosening to screw rod.
At the use initial stage, adopt lock screw 5 to lock compressing locking block 6 pairs of screw rod outer wall mineralization pressures, improve the tightness of screw rod, prevent screw bolt loosening, use the later stage, when screw rod not easily loosens due to the reason such as to get rusty, Lubricants can be added wherein by locking hole 3, be convenient to screw bolt loosening.
