Abstract
The utility model discloses a tamper-proof three-groove nut which comprises a nut body, wherein the upper end of the nut body is provided with a cap opening end part, the lower end of the nut body is provided with a mounting contact body, the nut body is arranged in a truncated cone shape with a narrow top and a wide bottom, the middle of the nut body is provided with a threaded hole, the side edge of the nut body is provided with three groups of notches which are arranged at equal intervals, and the depths of the notches are consistent up and down. The nut body is narrower than a common nut so as to adapt to a narrow space, the three-groove sleeve drill bit and the driving handle or the open spanner are used for installation, other common tools cannot disassemble and install the nut body, and objects fixed by the nut body are prevented from being stolen; after the object is installed using the tamper-resistant tri-groove nut, the object is protected from corrosion in a humid environment.
Description
Technical Field
The utility model relates to the technical field of nuts, in particular to a tamper-proof three-groove nut.
Background
Nut cooperation bolt has the wide application in the installation of object (for example sign, lighting apparatus and display screen) in public space, and in case the nut is bulky, the size is wide, just is unfavorable for the fastening installation in narrow and small space, and current nut structure is ordinary, and general instrument just can be dismantled it, and the object through ordinary nut installation is stolen easily, for this reason, we have put forward a kind of tamper-proof three-groove nut.
SUMMERY OF THE UTILITY MODEL
The present invention is directed to a tamper-resistant tri-groove nut that solves the problems set forth above in the background art.
In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a prevent falsifying three groove nut, includes the nut body, the upper end of nut body is equipped with the hat mouth tip, nut body lower extreme is equipped with the installation contact, the nut body is narrow round platform shape setting wide down, the middle part of nut body is equipped with the screw hole, the side of nut body is equipped with the notch that three equidistant settings of group, the degree of depth of notch is unanimous from top to bottom.
As a further optimization of the technical scheme, the width of the notch 4 is 4.22mm, the outer diameter of the lower end of the nut body is 20.87mm, and the height of the nut body is 8.76 mm. The upper end and the lower end of the notch extend to the end part of the cap opening and the installation contact body, and the installation contact body is adhered to the lower end of the nut body through glue.
Compared with the prior art, the utility model has the beneficial effects that: the nut body is narrower than a common nut so as to adapt to a narrow space, the three-groove sleeve drill bit and the driving handle or the open spanner are used for installation, other common tools cannot disassemble and install the nut body, and objects fixed by the nut body are prevented from being stolen; after the object is installed using the tamper-resistant tri-groove nut, the object is protected from corrosion in a humid environment.
Drawings
FIG. 1 is a schematic perspective view of the present invention;
FIG. 2 is a schematic top view of the present invention.
In the figure: 1 nut body, 2 installation contact, 3 cap mouth tip, 4 notches, 5 screw holes.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, 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.
Referring to fig. 1-2, the present invention provides a technical solution: a tamper-proof three-groove nut comprises a nut body 1, wherein the nut body 1 is made of 316 stainless steel materials, zinc-plated steel or zinc alloy materials;
the upper end of nut body 1 is equipped with cap mouth tip 3, 1 lower extreme of nut body is equipped with installation contact 2, nut body 1 is the round platform shape setting of narrow width down, the middle part of nut body 1 is equipped with screw hole 5, the side of nut body 1 is equipped with notch 4 that three equidistant settings of group, the degree of depth of notch 4 is unanimous from top to bottom.
The width of notch 4 is 4.22mm, the external diameter of nut body 1 lower extreme is 20.87mm, the height of nut body 1 is 8.76 mm.
The upper end and the lower end of the notch 4 extend to the cap opening end part 3 and the installation contact body 2, and the installation contact body 2 is adhered to the lower end of the nut body 1 through glue.
Specifically, the tamper-resistant three-groove nut is narrower than a common nut so as to adapt to a narrow space. The three-groove sleeve drill bit and the driving handle or the open spanner are used for installation, other common tools cannot disassemble and install the nut body 1, and objects fixed through the nut body 1 are prevented from being stolen;
using them, objects (e.g. signs, lighting and display screens) in the public space can be lowered. The nut is protected from corrosion in a wet environment, the zinc plated steel nut is coated, and the zinc alloy nut is light in weight and resistant to corrosion in the wet environment. The nut body 1 made of 316 stainless steel is not corroded by water, chemicals or salt spray.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
