Abstract
The utility model discloses a dustproof screw, which comprises a head, wherein the head is provided with a groove, an elastic part is arranged in the groove, and a blocking sheet is arranged at the upper part of the elastic part. In the use process, the utility model can effectively prevent impurities and the like from falling into the groove at the head of screw, has simple manufacture, can be used conveniently and can effectively improve the work efficiency.
Description
Technical field
The utility model belongs to the technical field of fastening piece in the five metals element, particularly a kind of dustproof screw.
Background technique
In mechanical processing industry, various Component need be assembled to fix and just can enter production line, and the general assembling fixation method that adopts is that screw is fixed.Common screw has outer-hexagonal head screw and socket head screw, and the screw terminal of socket head screw has individual inside groove, has foreign material such as iron filings, fractionlet to fall into easily in the work, and in the course of time, foreign material solidify in the screw terminal groove of socket head screw, is difficult to remove; Add some a plurality of Component and be installed together after fixing, the space is little, also is not easy to remove.When socket head screw stressed at work loosening after, need when fastening once more, the hexagon socket head spanner is put to be entered can't be fastening, brings very inconvenience to manufacturing operation, has a strong impact on working efficiency.
The model utility content
The purpose of this utility model provides a kind of foreign material such as iron filings, fractionlet that can prevent and falls into the dustproof screw in the screw terminal groove.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of dustproof screw comprises the head that has groove, is provided with elastic component in the groove, and elastic component top is provided with catch.
The external frame and the groove of catch are complementary.
In the elasticity releasing state of elastic component, the upper surface of catch is concordant with the screw head upper surface.
Elastic component is a spring.
In the utility model, a kind of dustproof screw, comprise the head that has groove, be provided with elastic component in the groove, elastic component top is provided with catch, the external frame and the groove of catch are complementary, in the elasticity releasing state of elastic component, the upper surface of catch is concordant with the screw head upper surface, this structural design, can prevent effectively that impurity etc. from falling in the groove, also be convenient to operation during work.Dustproof screw under normal circumstances, combining closely of catch and screw terminal can prevent effectively that impurity etc. from falling in the groove.When needing operation, wipe the dust on catch surface earlier, slightly firmly press down lower stop piece with spanner then in the effect of spring, get final product random fastening operation, after operation is finished, take out spanner, catch resilience under the effect of spring, it is concordant with the screw head upper surface that catch is continued, and can prevent effectively that then impurity etc. from falling in the groove.The utility model is made simple, and is easy to operate, can increase work efficiency effectively.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, a kind of dustproof screw comprises head 1, the bar portion 5 that has groove 2 and is positioned at screw thread 6 in the bar portion 5 that groove 2 bottoms are welded with spring 4, and spring 4 tops are welded with catch 3.The external frame of catch 3 and groove 2 are complementary.In the elasticity releasing state of spring 4, the upper surface of catch 3 is concordant with screw head 1 upper surface.
The utility model under normal circumstances, combining closely of the external frame of catch 3 and groove 2 can prevent effectively that impurity etc. from falling in the groove.When needing operation, wipe the impurity such as dust on catch 3 surfaces earlier, slightly firmly press down lower stop piece 3 with spanner then in the effect of spring 4, get final product random fastening operation, after operation is finished, take out spanner, catch 3 resilience under the effect of spring 4, it is concordant with screw head 1 upper surface that catch 3 is continued, and can prevent effectively that then impurity etc. from falling in the groove 2.
