Abstract
The invention discloses a locking sheet. The locking sheet is flaky and consists of a middle part which is upwards raised to form an arch shape and two flat ends which are positioned at two corresponding ends of the middle part and integrated with the middle part, and the locking sheet is in a shape similar to 'omega'; a through hole is machined in the center of the locking sheet; and the flat ends are respectively arranged in grooves symmetrically machined in the circumferential inner wall of a counter bore. The invention has the characteristics that the locking sheet is simple in structure and low in cost, solves the loosening problem in fastening and connection of an internal hexagonal jackscrew and an internal hexagonal screw and plays a role in preventing loosening and locking.
Description
Technical field
The present invention relates to mechanical field, be specifically related to the lock sheet of hexagonal jackscrew, the locking usefulness of socket head screw in a kind of being used for.
Background technique
Hexagonal jackscrew and socket head screw carries out fastening and connection in some mechanical assemblys, need using; But in particular cases (for example vibrate) at some; Jackscrew and socket head screw can become flexible; Therefore just need take certain proof measures, the domestic locking device that is not specifically designed to interior hexagonal jackscrew, and the lock washer cost that existing socket head screw is used is all than higher and reliability is on the low side.
Summary of the invention
The objective of the invention is to overcome above-mentioned not enough problem, provide a kind of internal hexagonal jackscrew and socket head screw to carry out effectively locking lock sheet.
The present invention for realizing the technological scheme that above-mentioned purpose adopted is: a kind of lock sheet; Said lock sheet is an en plaque; Overarch by raising up shape intermediate portion and be positioned at corresponding two ends, said intermediate portion and with said intermediate portion be that two flat end of one are formed; Make said lock sheet shape approximation in " Ω " type, said lock sheet central position is processed with through hole, and said flat end is installed in respectively in the groove of symmetry processing on the circumferential inner wall of counterbore.
The width of said flat end and the width of said groove are complementary.
Corresponding two ends and described flat end that said intermediate portion is other all are processed as circular arc.
Characteristics of the present invention are: simple in structure, cost is low, solved interior hexagonal jackscrew and socket head screw in loosening phenomenon fastening, that occur in connecting, and play the effect of locking locking.

Fig. 1 is a plan view of the present invention;
Fig. 2 is that the A-A of Fig. 1 is to sectional view;
Fig. 3 installs counterbore groove plan view of the present invention;
Fig. 4 installs counterbore groove plan view of the present invention;
Fig. 5 is that the present invention installs and uses schematic representation.
Wherein: 1, lock sheet 2, intermediate portion 3, through hole 4, flat end 5, counterbore 6, groove.
Embodiment
Shown in Fig. 1-5; Lock sheet 1 of the present invention is an en plaque; Overarch by raising up shape intermediate portion 2 and be positioned at 2 corresponding two ends, said intermediate portion and form for two flat end 4 of one with said intermediate portion 2; Make said lock sheet 1 shape approximation in " Ω " type, and said intermediate portion 2 other corresponding two ends and described flat end 4 all are processed as circular arc, said lock sheet 1 central position is processed with through hole 3; After interior hexagonal jackscrew or socket head screw are screwed into counterbore 5; Two flat end 4 of lock sheet 1 are installed in respectively in the groove 6 of symmetry processing on the circumferential inner wall of counterbore 5, the width of the width of said flat end 4 and said groove 6 is complementary, and the through hole 3 aimed on the said lock sheet 1 of tool using pours lock sheet 1 part in the cavity of interior hexagonal jackscrew or socket head screw head then; This moment through hole 3 marginal lacerations and be close in the cavity inwall of hexagonal jackscrew or socket head screw head, thereby play the effect of locking locking.
The above; Be merely the preferable embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any technician who is familiar with the present technique field is equal to replacement or change according to technological scheme of the present invention and inventive concept thereof in the technical scope that the present invention discloses, all should be encompassed within protection scope of the present invention.
