Abstract
The purpose of this utility model is to propose a kind of easy to assembly, plastic component connecting structure that cost is low, for the connection of plastic parts.Plastic component connecting structure of the present utility model comprises the first plastic parts and the second plastic parts, and key is that described the first plastic parts is provided with at least two buckles, and the outside, end of described buckle is provided with outwardly button bit; Described the second plastic parts is provided with the sleeve of fore-set and an end opening, and described fore-set is positioned at sleeve, and the sleeve wall of described fore-set side is provided with the opening that can snap in described button bit; Described fore-set when buckle stretches into sleeve can with the interior side contacts of buckle, and the button bit in buckle outside is squeezed in the opening of sleeve lateral wall.Plastic component connecting structure of the present utility model has adopted special cooperating structure, can realize the reliable connection of two plastic parts, and low cost of manufacture, easy to assembly, is very suitable for the connection of the plasthetics such as plastic box.
Description
Technical field
The utility model belongs to plasthetics technical field, specially refers to a kind of plastic component connecting structure.
Background technique
Conventionally plastic parts be connected with following several mode: screw is fixed, ultrasonic connection, glue connect, heat is melted and connected and button bit connects, and wherein screw is fixing used manually more, and assembling is wasted time and energy, and efficiency is lower; Ultrasonic connection needs purchase of equipment and some material can not be ultrasonic, has therefore been subject to certain restriction; The manufacturing efficiency that glue connects is low, and processing cost is high; Heat melt connect need special device and work efficiency low; The connection of tradition button bit is easily hit and splits.
Summary of the invention
The purpose of this utility model is to propose a kind of easy to assembly, plastic component connecting structure that cost is low, for the connection of plastic parts.
Plastic component connecting structure of the present utility model comprises the first plastic parts and the second plastic parts, and key is that described the first plastic parts is provided with at least two buckles, and the outside, end of described buckle is provided with outwardly button bit; Described the second plastic parts is provided with the sleeve of fore-set and an end opening, and described fore-set is positioned at sleeve, and the sleeve wall of described fore-set side is provided with the opening that can snap in described button bit; Described fore-set when buckle stretches into sleeve can with the interior side contacts of buckle, and the button bit in buckle outside is squeezed in the opening of sleeve lateral wall.
When the first plastic parts is connected with the second plastic parts, first the buckle of the first plastic parts is inserted in the sleeve of the second plastic parts, when buckle stretches into sleeve certain depth, will contact with fore-set, continue again to press the first plastic parts, make fore-set push laterally buckle, the button bit of buckle will snap in because of the inclination of buckle to the opening of sleeve lateral wall, because fore-set can stop bounce-back, therefore also just stoped buckle to deviate from sleeve, thereby realized the first plastic parts, be connected with the reliable of the second plastic parts.Above-mentioned buckle and the first plastic parts, sleeve, fore-set and the second plastic parts all can form by integrated injection molding, have saved cost, and whole connection procedure is without any instrument, and efficiency of assembling is high and connect reliable.
Specifically, described the first plastic parts is provided with open tubular column, the top-slitting of described open tubular column, thus at the top of open tubular column, form buckle; Described fore-set is positioned on the central axis of sleeve, and the diameter of fore-set is greater than the internal diameter of described open tubular column.The buckle forming like this can have a plurality of, and rounded arrangement, can provide uniform power for the connection of the first plastic parts, the second plastic parts.
Further, insert the inner side of buckle for convenience of fore-set, the end of described fore-set is that the inner side surface of taper or described button bit has guiding surface.
Further, the opening of described the second plastic parts sleeve extends to the bottom of sleeve and passes the second plastic parts, so that manufacture the opening of processing sleeve.
Further, the outer side surface of described button bit has guiding surface, to facilitate, buckle is stretched in sleeve.
Plastic component connecting structure of the present utility model has adopted special cooperating structure, can realize the reliable connection of two plastic parts, and low cost of manufacture, easy to assembly, is very suitable for the connection of the plasthetics such as plastic box.
Accompanying drawing explanation
Fig. 1 is the structural representation of the first plastic parts.
Fig. 2 is the structural representation of the second plastic parts.
Fig. 3 is the catenation principle figure of the first plastic parts and the second plastic parts.
Embodiment
Contrast accompanying drawing below, by the description to embodiment, embodiment of the present utility model is described in further detail as the effect of the mutual alignment between the shape of each related member, structure, each several part and annexation, each several part and working principle etc.
Embodiment 1:
As shown in the figure, the present embodiment plastic component connecting structure comprise the first plastic parts 1 and the second plastic parts 2, the first plastic parts 1 is provided with the first buckle 11 and the second buckle 12, shape and the size of the first buckle 11 and the second buckle 12 are all identical, and the outside, end of the first buckle 11 and the second buckle 12 is equipped with the button bit 13 of protrusion; The second plastic parts 2 is provided with the sleeve 22 of fore-set 21 and an end opening, and described fore-set 21 is positioned at sleeve 22 and towards sleeve 22 opening directions; Sleeve 22 walls of fore-set 21 sides are provided with the opening 23 that can snap in described protrusion button bit 13, and this opening 23 extends to the bottom of sleeve 22 and passes the second plastic parts 2; Fore-set 21 is positioned on the central axis of sleeve 22, and the width of fore-set 21 is greater than the gap between the first buckle 11 and the second buckle 12.
When the first plastic parts 1 is connected with the second plastic parts 2, first the buckle of the first plastic parts 1 is inserted in the sleeve 22 of the second plastic parts 2, when the first buckle 11 and the second buckle 12 stretch into sleeve 22 certain depth, will contact with fore-set 21, continue again to press the first plastic parts 1, make fore-set 21 to both sides, push the first buckle 11 and the second buckle 12, thereby stretch to the gap between the first buckle 11 and the second buckle 12, in this process, button bit 13 will snap in because of the inclination of the first buckle 11 and the second buckle 12 to the opening 23 of sleeve 22 sidewalls, because fore-set 21 can stop the bounce-back of the first buckle 11 and the second buckle 12, therefore also just stoped and protruded the opening 23 that button bit 13 is deviate from sleeve 22, thereby having realized the first plastic parts 1 is connected with the second the reliable of plastic parts 2.Above-mentioned buckle and the first plastic parts 1, sleeve 22, fore-set 21 and the second plastic parts 2 all can form by integrated injection molding, have saved cost, and whole connection procedure is without any instrument, and efficiency of assembling is high and connect reliable.
