Abstract

The invention discloses a bolt counterbore structure on a plastic part, which comprises a counterbore, wherein, a bolt fixing part is arranged on the counterbore; the plastic part is arranged and fixed in the front of the inner wall or the bottom of furniture; a bolt is used for pressing the bolt fixing part and locked by the fixing part which is cracked and deformed after penetrating the fixingpart so that the tip of the bolt is fixed in the counterbore before penetrating the counterbore; therefore, people are not required to hold the bolt by hands, only need to press the plastic part against the preassembling position of the inner wall or the bottom of the furniture by one hand and screw by a screw driver by the other hand; after assembling, the fixing part is concealed between the bolt and the counterbore; the bolt counterbore structure of the invention greatly reduces the difficulty of an operation process, simplifies assembling work and improves assembling efficiency, thus beinga bolt counterbore structure widely applied to the plastic parts connected with the furniture.

Description

Screw counter bore structure on the working of plastics

Technical field

The present invention relates to a kind of mounting hole, particularly a kind of screw counter bore structure that is positioned on the working of plastics.

Background technique

At present, the common plastic fittings or the link that are installed on the furniture all are on these parts through hole to be set usually, pass with screw that through hole hammers on the furniture then or innerly fixedly connected with it, the overall appearance that has influence on product can be provided with counterbore nut top and screw are maintained an equal level on working of plastics in order to make screw hammer into that rear nut does not expose the outside of working of plastics; Yet, no matter be through hole or counterbore, after passing the hole, screw hammers in the process of furniture, need one hand-held screw, other hand hammers into nail hammer or screws in screwdriver set, and when especially plastic fittings being fixed to furniture bottom surface or inwall, the operation of hand-held screw is very inconvenient, at the existing shortcoming of existing mounting hole, be necessary to make improvements.

Summary of the invention

In order to overcome the deficiencies in the prior art, the invention provides the screw counter bore structure on a kind of working of plastics rational in infrastructure, easy to use.

The technical solution adopted for the present invention to solve the technical problems is:

Screw counter bore structure on the working of plastics comprises counterbore, and described counterbore is provided with the screw part.

In the present invention, described screw part comprises many elasticity card muscle that stretch to its top that counterbore inwall bottom is set, and the through hole screw body of rod that these elasticity card muscle are surrounded adapts.

In the present invention, described elasticity card muscle inwall or counterbore end face also are provided with the bounding means that is easily penetrated by screw.

In the present invention, described bounding means is a thin slice.

In the present invention, described thin slice center is provided with depression.

In the present invention, described bounding means is an annular flake.

In the present invention, described bounding means is radially formed towards the thin muscle that extend at its center along counterbore by being positioned at elasticity card muscle inwall.

The invention has the beneficial effects as follows: working of plastics is installed and fixed before furniture inwall or the bottom, earlier screw is pushed the screw part, screw is blocked by the fixed block of cracking back deformation after wearing out fixed block, make the tip of screw before penetrating counterbore, just be fixed in the counterbore, like this, people must not hand screw, need only pin working of plastics on the other hand with the pre-installed position of its roof pressure in furniture inwall or bottom, other hand screws in screwdriver set and gets final product, installing the back fixed block is hidden between screw and the counterbore, greatly reduce the difficulty of operating process, simplified installment work and installation efficiency.

Embodiment

Referring to figs. 1 through Fig. 5, the screw counter bore structure on the working of plastics comprises counterbore 1, and described counterbore 1 is provided with screw part 2; This screw part 2 comprises many elasticity card muscle 21 that stretch to its top that counterbore 1 inwall bottom is set, the through hole and the screw body of rod that these elasticity card muscle 21 are surrounded adapt, and the bearing of trend of these elasticity card muscle 21 differs and is decided to be straight line, and " く " shape broken line and curve also are fine; And, also be provided with the bounding means 22 that is easily penetrated at elasticity card muscle 21 inwalls by screw, and the very thin thickness of this bounding means 22, to approach than elasticity card muscle 21 and working of plastics, this bounding means 22 is a thin slice usually; And elasticity card muscle 21 and bounding means 22 among the present invention all are made of plastics.

Before working of plastics is installed and fixed furniture inwall or bottom, earlier screw is pushed thin slice, screw is worn out and is ftractureed behind the thin slice and the thin slice of deformation takes place and tube wall that elasticity card muscle 21 is surrounded blocks, make the tip of screw before penetrating counterbore, just be fixed in the counterbore 1, even hand-held working of plastics turns, screw can not fall under the effect of gravity yet, like this, people must not hand screw, need only pin working of plastics on the other hand with the pre-installed position of its roof pressure in furniture inwall or bottom, an other hand screwdriver set screws in and gets final product, installing back thin slice and elasticity card muscle 21 is hidden between screw and the counterbore 1, people operate very convenient, have simplified installment work and installation efficiency.

In order to make screw can aim at attachment hole, guarantee that screw is offset hammering into Shi Buhui, can be provided with depression 23 at the thin slice center, this depression 23 is shaped as taper shape to adapt to the tip of screw front end usually.

Bounding means 22 is except being the plate thin slice, can also be provided with the annular flake of through hole for the center, its center is coaxial ideal with counterbore 1 center, can guarantee that like this screw hammers into center, position, back, this structure and preceding a kind of structure are to be equal to mutually or approximate, also can play same limit effect after screw is worn out.

With reference to Fig. 6, Fig. 7, bounding means 22 is radially formed towards the thin muscle that extend at its center along counterbore 1 by being positioned at elasticity card muscle 21 inwalls, this structure is the third structure of bounding means 22, these thin muscle can cross at counterbore 1 center, can also make counterbore 1 center reserve a through hole position, during use screw aimed at intersection or connect sky and push and get final product, screw is worn out or is pushed thin muscle and makes it be subjected to downward power and deformation takes place and clamp screw with elasticity card muscle 21, be limited to effect with above-mentioned two kinds identical.

With reference to Fig. 8, described bounding means 22 is arranged on counterbore 1 end face, and the structure of this bounding means 22 is identical with three kinds of structures in the mode of execution one, the identical limit effect of a kind of embodiment before screw is worn out and also can be played behind the bounding means 22.

With reference to Fig. 9, Figure 10, these two kinds of mode of executions are not comprise bounding means 22, and only only flexible card muscle 21, the extended height of described card muscle should be tried one's best near counterbore 1 end face or be maintained an equal level with it; During use, directly screw is passed the through hole that elasticity card muscle 21 surrounded and get final product, can play position-limiting action equally; Also among the scope that the present invention protected.

The present invention is rational in infrastructure, easy to use, be a kind of be widely used in working of plastics that furniture is connected on screw counter bore structure.
