Abstract
The utility model discloses a novel plastic piece fastening structure, which comprises a fastening point and a fastening hole which are in interference fit with each other. The fastening structure is characterized in that: a protrusion is formed on the inner wall of the fastening hole. The fastening structure is simple; the protrusion is formed on the inner wall of the fastening hole, so that transverse extrusion force is enhanced when the fastening point is fastened into the fastening hole; and the firmness of the fastening structure is ensured, so that a plastic piece is prevented from dropping, and the connecting quality of a product is ensured.
Description
Technical field
The utility model relates to a kind of fastening structure, especially relates to a kind of fastening structure of working of plastics, belongs to plastic article linkage structure technical field.
Background technique
As everyone knows, in the linkage structure of working of plastics and working of plastics, often can use fastening structure, promptly button point and with the button hole structure of button point interference fit, realizing the connection of working of plastics, traditional fastening structure, the soundness of connection is not strong, comes off easily.
Summary of the invention
To the deficiency that existing technology exists, the purpose of the utility model is to provide a kind of and is connected firmly, the novel plastic spare fastening structure of difficult drop-off.
The technological scheme that the utility model adopts is:
A kind of novel plastic spare fastening structure comprises button point and button hole, and described button point and button hole interference fit is characterized in that, are formed with convexity on the internal face of described button hole.
Described convexity is provided with a plurality of.
And described convexity is distributed on the internal face of button hole, to form the equilibrium of fastening force.
The beneficial effect of the utility model is: the utility model is simple in structure, through on the internal face of button hole, being formed with convexity, makes the button point in buckling into the process of button hole; Strengthen horizontal extruding force; And the fastness of assurance fastening structure prevents that working of plastics from coming off, and has guaranteed the quality of connection of product.
Description of drawings
Fig. 1 is the utility model one embodiment's a structural representation.
Main reference character implication is among the figure:
1, button point 2, button hole 3, convexity.
Embodiment
Below in conjunction with accompanying drawing, the technological scheme of the utility model is elaborated.
Fig. 1 is the utility model one embodiment's a structural representation.
As shown in Figure 1: a kind of novel plastic spare fastening structure, comprise button point 1 and button hole 2, described button point 1 and button hole 2 interference fit, and be formed with protruding 3 on the internal face of described button hole 2.
Described protruding 3 can be provided with a plurality ofly, and can be distributed on the internal face of button hole 2, and to form the equilibrium of fastening force, in this mode of execution, protruding 3 is two, is symmetrical set.
Described button point 1 is arranged on one of them working of plastics that need connect, and button hole 2 then is arranged on the working of plastics that another one need connect, because button point 1 is an interference fit with button hole 2; Therefore, after button point 1 buckled into button hole 2, itself and button hole 2 formed a fixed connection; And the utility model is when button point 1 inserts button hole 2, and at first under the effect of mating force, the convexities 3 in the button hole 2 himself are being under the situation of elastic material; Deformation takes place; And after button point 1 snapping is accomplished, the extruding force that then protruding 3 make-up points 1 entad form, feasible button point 1 can be fixed together with button hole firmly; And the situation that the working of plastics that is not easy to occur connecting comes off has guaranteed the quality of connection of product.
As stated, although represented and explained the utility model that with reference to specific preferred embodiment it shall not be construed as the restriction to the utility model self.Under the spirit and scope prerequisite of the utility model that does not break away from the accompanying claims definition, can make various variations in form with on the details to it.
Claims (3)
