CN2386243Y - Strengthening fixing structure for screw hole - Google Patents

Abstract

The utility model relates to a strengthening fixing structure for a screw hole. A plate body with the proper thickness is concavely provided with a circular groove. A screwing fixing surface with the thinner thickness is formed on the bottom part of the groove, and the central position of the screwing fixing surface is penetrated with a screw hole with proper size. The periphery of the groove on the screwing fixing surface is circularly provided with a plurality of symmetrical strengthening ribs to intensify the intensity of the screwing fixing surface. When the utility model is used for fixing a screw, the head part of the screw is difficult to lead the crack and the damage of the screwing fixing surface caused by the improper force application. The head part of the screw can be buried in the plate body, or the exposed part of the head part of the screw can be reduced. Therefore, the utility model is convenient for the assembly and the construction.

Description

The screw reinforcing structure

The utility model relates to the screw of plate body, refers to a kind of screw reinforcing structure especially, and this screw reinforcing structure can make when the solid screw of spiral shell, buries screw head simultaneously underground in screw, and and can reach and avoid the inner pressurized of screw to wreck.

Existing plate body is when being fixed at other objects, generally be on plate body, to wear several screws earlier, wear wherein by screw again and be fixed on the object, and because screw head all is to expose on the plate body, make in the process that article are assembling, the often influence of coping screw head and touching and the phenomenon of clip, and cause puzzlement when installing, and also influence the aesthetic property of exterior; For solving above shortcoming, the someone utilizes and be concaved with a groove on this screw, makes screw head can use after spiral shell is solid and is placed in this groove, or reduce its exposed parts so that install; Only owing to after being drilled with groove, often make the solid face attenuation of spiral shell and the intensity of screw reduce, so when being spirally connected such as the application of force improper, and promptly can cause this spiral shell to consolidate the phenomenon that face breaks and damages.

Therefore, this creator is based on the research and development of engaging in Related product for many years, and the practical experience of selling, it is the idea of thinking and create improvement, poor its people's professional knowledge, through research and design, special topic discussion in many ways, and after repeatedly studying sample and improvement, can create a kind of screw reinforcing structure eventually.So,

Main purpose of the present utility model is to provide a kind of screw reinforcing structure, it mainly is the structural strength that can strengthen the solid face of spiral shell, causes damage when avoiding spiral shell solid, also makes screw head can be embedded in the plate body simultaneously, or reduce its exposed parts, so that assembling and construction.

The purpose of this utility model is achieved in that a kind of screw reinforcing structure, it mainly is to be concaved with a groove on the plate body of a suitable thickness, and constitute the solid face of spiral shell of a thinner thickness at this bottom portion of groove, the centre of the solid face of this spiral shell then is equipped with a suitably big or small screw, it is characterized in that: the groove peripheral region on the solid face of this spiral shell is equipped with the strengthening rib of a plurality of symmetries, uses the support strength that can strengthen the solid face of this spiral shell.

Be equipped with a lead angle on this strengthening rib, so that this screw is installed in this screw.

This groove is to be a toroidal.

The utility model has the advantages that: utilize the setting of strengthening rib, can strengthen the structural strength of the solid face of spiral shell, cause damage when avoiding spiral shell solid; Screw head is embedded in the plate body, or reduces its exposed parts, be convenient to assembling and construction.

Now further understand and understanding for making structure characteristic of the present utility model and the effect reached had, careful assistant is with preferred embodiment figure and cooperate detailed explanation as the back:

The accompanying drawing simple declaration:

Fig. 1 is a schematic perspective view of the present utility model;

Schematic representation when Fig. 2 is fixed at the utility model for screw;

Sectional view when Fig. 3 is fixed at the utility model for screw.

As shown in Figure 1, the utility model mainly is to be concaved with a circular groove 11 on the plate body 1 of a suitable thickness, and the solid face 13 of the spiral shell that constitutes a thinner thickness in these groove 11 bottoms, the centre of the solid face 13 of this spiral shell then is equipped with a suitably big or small screw 15, make screw 2 be able to spiral shell admittedly wherein, in addition, for strengthening the support strength of the solid face 13 of spiral shell, groove 11 peripheral regions on the solid face 13 of this spiral shell are equipped with the strengthening rib 17 of a plurality of symmetries, use the intensity of strengthening the solid face 13 of spiral shell.

Seeing also shown in Fig. 2,3, is respectively schematic representation and the sectional view when being fixed at the utility model for screw.When the utility model desires to carry out spiral shell when solid, can pass screw 15 and be fixed on another object by this screw 2, at this moment, the head 21 of this screw 2 can be embedded in the groove 11 or little being exposed to outside the groove 11 fully, uses reaching the assembling and keep purpose attractive in appearance of being convenient to construct; And because after being arranged with groove 11, the solid face 13 of this spiral shell is owing to thin its intensity that makes is comparatively fragile, so when when groove 11 inner circumference edges are provided with this strengthening rib 17, be formed with a tough bracing force around can making the solid face 13 of this spiral shell, make that when the solid screw 2 of spiral shell these screw 2 heads 21 are difficult for causing spiral shell to consolidate the damage of breaking of face 13 because of the application of force improperly; In addition, can be equipped with a lead angle 171 on the strengthening rib 17 of the present utility model, so that this screw 2 is installed in this screw 15.

In sum, the utility model is an innovative design that has novelty, progressive and can supply usability on the industry undoubtedly, so propose utility application in accordance with the law.

Only the above, it only is a preferred embodiment of the present utility model, be not to be used for limiting the scope that the utility model is implemented, such as the equivalence of doing according to the described shape of technical solutions of the utility model, structure, feature and spirit changes and modifies, and all should be included in the technical solution of the utility model scope.
