Abstract
The utility model provides an one -way phillips screw mainly includes screwhead, screw rod, screw thread and one -way cross recess, be equipped with straight flute wall and spiral curved surface in the one -way cross recess. The utility model discloses simple structure, convenient to use can effectually prevent that the screw from being back -outed to the equipment that plays, facility are not destroyed, effect that the property did not lose.
Description
Technical field
The utility model relates to a kind of unidirectional cruciform slot screw, belongs to technical field of fastening.
Background technique
Screw is a kind of threaded connector, for connecting each part.At some equipment, facility that outdoor mounted uses, owing to using common screw to connect, usually can be dismantled destruction by people, make equipment, facility suffers destruction, lose, property incurs loss, so existing screw technique is perfect not enough.
As shown in Figure 1, it is made up of screw head 1, screw rod 2, screw thread 3, cross recess 4 cruciform slot screw of prior art, has straight trough wall 401 and 402 in cross recess 4; During use, insert cross recess 4 with screw driver, screw driver turns clockwise, and limits because there being straight trough wall 401, screw driver drives screw to screw in tapped hole, and connect component, screw driver is rotated counterclockwise, because there being straight trough wall 402 to limit, screw driver drives screw to screw out from tapped hole, dismounting component.
Model utility content
The purpose of this utility model be in order to solve exist in prior art dismantled destruction by people, make equipment, facility suffers to destroy, lose, property such as to incur loss at the problem, thus provides a kind of unidirectional cruciform slot screw.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of unidirectional cruciform slot screw, mainly comprises screw head, screw rod, screw thread and unidirectional cross recess; Straight trough wall and spiral camber is provided with in described unidirectional cross recess.
Described screw head is countersunk raised head type.
Described screw head is cylinder head dummy.
The beneficial effect of employing technique scheme is:
The utility model structure is simple, easy to use, can effectively prevent screw to be screwed out, thus play equipment, facility is not destroyed, the effect that property does not lose.
Accompanying drawing explanation
Fig. 1 is the structural representation of the common cruciform slot screw of prior art;
Fig. 2 is the plan view of Fig. 1;
Fig. 3 is the structural representation of a kind of unidirectional cruciform slot screw of the utility model;
Fig. 4 is the plan view of Fig. 3;
In figure: 1-screw head, 2-screw rod, 3-screw thread, 4-cross recess, 401-straight trough wall, 402-straight trough wall, 5-screw head, 6-screw rod, 7-screw thread, 8-unidirectional cross recess, 801-straight trough wall, 802-spiral camber.
Embodiment
As shown in Figure 3,4, a kind of unidirectional cruciform slot screw, mainly comprises screw head 5, screw rod 6, screw thread 7 and unidirectional cross recess 8; Straight trough wall 801 and spiral camber 802 is provided with in described unidirectional cross recess 8.
During use, insert unidirectional cross recess 8 with screw driver, screw driver turns clockwise, and because there being straight trough wall 801 to limit, screw driver drives screw to screw in tapped hole, connects component; When screw driver is rotated counterclockwise, what touch due to screw driver is spiral camber 802, and now screw driver can only slide along spiral camber 802, and screw driver can only skid in unidirectional cross recess 8, screw cannot be driven to rotate, prevent screw to be screwed out.
Claims (3)
