Description

Anti-twisting cross screw

Technical Field

The utility model relates to a screw, a concretely designs prevent twisting colored cross screw.

Background

The size of the shell mounting screws used on the small household appliances is between 5 and 8mm, the screws are easy to screw the cross-shaped dismounting groove in the process of dismounting the screws along with the long-time use of the appliances, namely the cross-shaped dismounting groove is damaged, and the screws are usually required to be forcibly and violently dismounted after the cross-shaped groove is damaged, so that the shell of the appliances is easy to damage.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a cross screw is twisted and is also taken off the screw smoothly under the circumstances of flower, can also play rust-resistant, prevent drawing one kind of that hinders the people and prevent twisting flower cross screw.

The anti-twisting cross screw comprises a screw body, wherein the screw body comprises a screw cap and a screw rod, a cross groove is formed in the screw cap, two linear clamping edges are symmetrically processed on the circumference of a circular screw cap, a rubber protective sleeve is sleeved in the circumferential direction of the screw cap, the outer contour of the rubber protective sleeve is circular, the part of the processed screw cap clamping edge which is cut off is filled by the part of the rubber protective sleeve, and the clamping edge and the connecting part of the rubber protective sleeve are in smooth transition.

The utility model has the advantages that: (1) when the cross groove on the screw cap is damaged, after the rubber protective sleeve is removed, the clamping part is clamped by a pliers or a spanner to rotate, so that the screw can be rotated, and the screw is taken out; (2) because the clamping edge is cut off on the basis of the nut, a sharp corner is formed after the machining, the part cut by the nut is filled up by the rubber protective sleeve, the appearance is restored to the arc-shaped structure of the original nut, and the rubber protective sleeve plays a role in protecting and prevents the sharp corner of the nut from scratching people; (3) the rubber protective sleeve wraps the screw cap, so that the screw cap can be protected and is prevented from being corroded; (4) rubber gasket and rubber protective sheath integrated into one piece, rubber gasket cover make the parcel structure more firm on the screw rod, and rubber gasket can also play reinforcing screw and installation face friction, the effect of relaxing simultaneously.

Further, the bottom surface of nut is equipped with the rubber gasket, and the rubber gasket cover is on the screw rod, rubber protective sheath and rubber gasket be integrated into one piece mechanism.

Further, a rubber protective layer is further arranged on the surface of the screw cap, a cross-shaped cutting seam is formed in the rubber protective layer and is arranged right above the cross-shaped groove, and the rubber protective layer and the rubber protective sleeve are of an integrally formed structure. When the screwdriver is used for disassembly, the screwdriver can be pressed into the cross-shaped groove by aligning with the cross-shaped cutting seam, so that the screw cap can be protected to the maximum extent under the condition of not influencing the normal disassembly work,

further, rubber protective layer, rubber protective sheath and rubber gasket are integrated into one piece structure.

Furthermore, the processing positions of the two symmetrically arranged clamping edges are aligned with two centrosymmetric right angles crossed in a cross shape on the cross groove.

Further, the outer diameter of the screw cap is 5-8 mm.

fig. 2 is a top view of fig. 1.

In the figure, 1 is a nut, 2 is a screw, 3 is a cross groove, 4 is a clamping edge, 5 is a rubber protective sleeve, 6 is a rubber gasket, 7 is a rubber protective layer, and 8 is a cross cutting seam.

Detailed Description

The invention will be described in further detail with reference to the following drawings and detailed description:

according to the scheme, the anti-twisting cross screw comprises a screw body, wherein the screw body comprises a screw cap 1 and a screw rod 2, and the outer diameter of the screw cap 1 is 5-8 mm. The cross groove 3 has been seted up on the nut 1 the symmetry processing has two sharp shape centre gripping limits 4 on circular nut 1's the circumference, and centre gripping limit 4 is amputated on circular nut 1's basis, and nut 1 surface structure is the arc surface, and processing centre gripping limit 4 is equivalent to processing out two planes in nut 1's both sides, and the position of the centre gripping limit 4 processing that two symmetries set up is the right angle of two cross centrosymmetries of cross on aiming at cross groove 3. The rubber protective sleeve 5 is sleeved on the circumferential direction of the nut 1, the outer contour of the rubber protective sleeve 5 is circular, the part of the clamping edge 4 of the processed nut 1, which is cut off, is filled by the part of the rubber protective sleeve 5, the appearance of the nut 1 is restored to be an original circular arc surface structure, and the connecting part of the clamping edge 4 and the rubber protective sleeve 5 is in smooth transition. The bottom surface of nut 1 is equipped with rubber gasket 6, and rubber gasket 6 overlaps on screw rod 2. The surface of nut 1 still is equipped with rubber protection layer 7, has seted up cross joint-cutting 8 on the rubber protection layer 7, and cross joint-cutting 8 is established directly over cross recess 3, and when using the screwdriver to dismantle, the screwdriver aims at cross joint-cutting 8 and presses into and can stretch into cross recess 3, and the at utmost carries out the omnidirectional protection to nut 1 under the condition that does not influence normal dismantlement work. The rubber protective layer 7, the rubber protective sleeve 5 and the rubber gasket 6 are of an integrally formed structure.

The above description is only an example of the present invention, and the common general knowledge of the known specific structures and characteristics of the embodiments is not described herein. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
