Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that if directional indications (such as … …, which is up, down, left, right, front, back, top, bottom, inner, outer, vertical, transverse, longitudinal, counterclockwise, clockwise, circumferential, radial, axial) are provided in the embodiments of the present invention, the directional indications are only used for explaining the relative position relationship, motion condition, etc. of the components at a specific posture (as shown in the attached drawings), and if the specific posture is changed, the directional indications are changed accordingly.
In addition, if there is a description relating to "first" or "second", etc. in the embodiments of the present invention, the description of "first" or "second", etc. is for descriptive purposes only and is not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.
As shown in fig. 1 to 3, an anti-detachment screw structure for a computer case includes a first screw 1 and a second screw 2 detachably mounted on the first screw 1, the first screw 1 is used for fixing a glass side plate on the computer case, the first screw 1 is provided with a non-regularly arranged clamping hole 31, the second screw 2 is provided with at least two clamping posts 32 matched with the clamping hole 31, and the clamping posts 32 can extend into the clamping holes 31 and drive the first screw 1 to rotate through the second screw 2.
When using, be for the irregularity form (the regularity form is like a straight line, cross or pentagon) because of first screw 1's card hole 31, therefore conventional tool can't open it, first screw 1's first nut 11 part is the platykurtic setting simultaneously, and the periphery is smooth, consequently can't open through the hand, effectively avoided the improper to open, need just can realize opening of curb plate through second screw 2's use, effectively avoided the improper of host computer hardware to take out, influence the use or the loss of property of host computer.
In the embodiment of the present invention, the outer side wall of the first nut 11 of the first screw 1 is rounded or tapered.
In the embodiment of the present invention, the locking hole 31 is recessed in the upper wall of the first nut 11 and is offset from the axis of the first nut 11. Because the clamping hole 31 deviates from the axis, the stress is not uniform when the first screw 1 is opened, and thus the abnormal opening of the first screw is effectively avoided.
In the embodiment of the present invention, the fastening holes 31 are circumferentially arranged around the axial center of the first nut 11, for example, the number of the fastening holes 31 may be 5, preferably an odd number.
In the present embodiment, there are three card holes 31. The first screw 1 is difficult to open by using the conventional common tool because the clamping hole 31 is deviated from the axial center, but the first screw is more conveniently opened by using a special tool because the clamping hole 31 is regularly distributed and is more uniformly stressed. The clamping holes can be positioned on the same circumferential line or different circumferential line positions.
In the embodiment of the present invention, the locking hole 31 has a circular shape. The corresponding clamping column 32 is also circular, wherein the diameter of the opening of the clamping hole 31 can be arranged in an inclined plane or the bottom end of the clamping column 32 is arranged in an inclined plane, so that the clamping column 32 on the square edge can be inserted.
In the embodiment of the present invention, the second nut 21 of the second screw 2 is partially provided with a limit thread 4. (thereby facilitating the opening of the first screw 1. of course, a knob design (e.g., a straight knob) may be directly provided at the nut portion, thereby allowing direct opening.
In the embodiment of the present invention, the second nut 21 of the second screw 2 is partially provided with a positioning hole, and the positioning hole is provided with a regular slot 5, where the regular slot 5 is, for example, a straight line, a cross, etc.
In the embodiment of the utility model, the first screw 1 and the second screw 2 are made of cut steel, and the surfaces of the first screw and the second screw are coated with zinc layers, so that the screws are prevented from being oxidized, and the service life is prolonged.
The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the technical solutions of the present invention, which are made by using the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
