Description

Anti-theft screw structure-improved

Technical field

The utility model is about a kind of screw structural, espespecially a kind ofly has concurrently antitheft and avoids stress to concentrate and produce the anti-theft screw structure-improved collapsing tooth, sliding tooth.

Background technique

The bolting elements such as various screw, nut are widely used in all trades and professions, especially on various mechanical package is fixing or be in every construction, communal facility, all can see and utilize various bolting element to carry out the locking action that is spirally connected, it has important and indispensable role, such bolting element is in use, it all has can for spiral shell establish tool cover to tap into head end that row spiral shell establishes action, to utilize spiral shell to establish tool cover to be connected on head end, and is spirally connected by bolting element and is locked in pre-position.

But though the bolting elements such as above-mentioned screw, nut can reach spiral shell establish expection effect in conjunction with every article, also use in its overall actual embodiment and find, this structure has its own shortcomings:

This bolting element is after spiral shell establishes combination, it establishes tool cover to tap into row spiral shell for spiral shell to establish the head end of action to be all directly expose state in one, the head end making unworthy personage very easily directly establish tool cover to be connected to this bolting element with spiral shell is again dismantled, and steal after article are dismantled, cause heavy losses unnecessary on property.

This bolting element is after spiral shell establishes combination, it establishes tool cover to tap into row spiral shell for spiral shell to establish the head end of action to be all directly expose state in one, the head end that this is exposed very easily suffers the improper collision deformation of external force or produces corrosion to damage, if when causing for carrying out dismounting action to this bolting element, often cannot dismantle smoothly, cause the very big inconvenience on using.

In view of this, how above-mentioned disappearance is forgone, be the utility model creator the place of technical difficulties for solving; Be and, the utility model creator, based on the experience being engaged in relevant industry for many years, takes great pains to attain one's goal through for many years and concentrates on studies, and studies improvement, has has finally successfully researched and developed the utility model, and makes novel a birth, to promote its effect.

Model utility content

Because above-mentioned shortcoming, it is antitheft that the utility model object is to provide a kind of energy, pressure during torsion can be made on average to disperse simultaneously, and avoid stress to concentrate, and avoids the novel anti-theft improved structure of screw making the sliding tooth of screw or collapse tooth.

The utility model anti-theft screw structure-improved, it includes a body, this body has a head and a screw section extended by this head, it is characterized in that: this body has a head and a screw section extend horizontally away by one end of this head, it is characterized in that: the end face of this head is provided with the first groove of one and ft connection, one with the second groove of ft connection and one and the 3rd groove of ft connection, one end of this first groove is communicated with the second groove and the 3rd groove respectively, form the hand tools that a Y shape containing space agrees with this Y shape containing space mutually for and plug use, between this first groove and this second groove and the 3rd groove, there is a predetermined angle, and between this second groove and the 3rd groove, also there is a predetermined angle.

Preferably, this predetermined angle is 100 degree ~ 120 degree.

The structure improved beneficial effect of the utility model anti-theft screw is: antitheft, pressure during torsion can be made on average to disperse simultaneously, avoids stress concentrate and make the sliding tooth of screw or collapse tooth.

Embodiment

For convenience of understanding this novel content, and the effect that can reach, hereby coordinate diagram to enumerate specific embodiment, be described in detail as follows:

As shown in Figure 1, be the utility model anti-theft screw structure-improved, it includes: a body 10, wherein

Body 10 has head 11 and the screw section 12 extended by this head 11, the end face of this head 11 is provided with the first groove 111 of one and ft connection, one with the second groove 112 of ft connection and one and the 3rd groove 113 of ft connection, one end of this first groove 111 is communicated with the second groove 112 and the 3rd groove 113 respectively, form a Y shape containing space 20, the both sides of this first groove 111 have a predetermined angle theta respectively and between this second groove 112 and the 3rd groove 113, and between this second groove 112 and the 3rd groove 113, also there is a predetermined angle theta.

Because the Y shape containing space 20 of head 11 need be mutually corresponding with hand tools, position due to the first groove 111, second groove 112 and the 3rd groove 113 is non-to be positioned on same axis, general purpose tool cannot be used to dismantle, therefore need to use special hand tools, reach antitheft effect by this.

Please refer to Fig. 2, above-mentioned each predetermined angle is 100 degree ~ 120 degree.

Y shape containing space 20 is except promoting except antitheft effect, first groove 111, second groove 112 and the 3rd groove 113 are on average located on head 11, when locking, point of application of force concentrates in each predetermined angle theta, the head 11 of further lifting hand tools and body 10 fixes degree, more easily concentrate strength on, not fragile, reduce the facts generation that Y shape containing space 20 is slided tooth or collapsed tooth.

Above-listed detailed description is illustrating for this novel possible embodiments, but embodiment is also not used to limit this novel the scope of the claims, allly do not depart from the equivalence that this novel skill spirit does and implement or change, all should be contained in the scope of the claims of the present utility model.

Claims (2)

1. an anti-theft screw structure-improved, it is characterized in that, it includes a body, this body has a head and a screw section extend horizontally away by one end of this head, it is characterized in that: the end face of this head be provided with one with the first groove of ft connection, one with the second groove of ft connection and one the 3rd groove with ft connection, one end of this first groove is communicated with the second groove and the 3rd groove respectively, form a Y shape containing space and plug use for the hand tools that is agreed with mutually with this Y shape containing space, the both sides of this first groove have a predetermined angle respectively and between this second groove and the 3rd groove, and between this second groove and the 3rd groove, also there is a predetermined angle.

2. anti-theft screw structure-improved as claimed in claim 1, is characterized in that this predetermined angle is 100 degree ~ 120 degree.
