Embodiment
See also Fig. 3, Fig. 4 A, Fig. 4 B, shown in Figure 5.The embodiment of the utility model snap fastener is described as follows with the structure of counter 20 with printing function: the counter 20 that the utlity model has printing function is provided with a casing (first member) 21 and one lid (second member) 23.Casing 21 is provided with an opening 22, uses the outside of stretching out casing 21 for print paper.Lid 23, for example the paper-tear picture member has a plate body 230, and plate body 230 is provided with a jagged paper-tear picture limit 231, uses for the seal paper of tearing.Casing 21 is respectively equipped with first guide member 211 of outstanding opening 22 in the both sides of opening 22; Casing 21 is provided with at least one in the rear end of opening 22, for example two first fasteners 212 and at least one, for example three buckling pieces 213; First fastener, 212 outstanding openings 22; Buckling piece 213, for example groove extends to the rear of opening 22.Plate body 230 is provided with second guide member 232 and second fastener 233 that extends respectively downwards; Second guide member 232 and second fastener 233 correspond respectively to first guide member 211 and buckling piece 213.
Characteristics of the present utility model are that the end face 2120 of first fastener 212 is provided with an inclined-plane 2121 to the inclination of the below of opening 22; Inclined-plane 2121 is near higher corner 2122 in the outside and the face institute constitutor that is tilted near inboard another lower corner 2123 to end face 2120 front ends respectively near an inboard higher corner 2123 by end face 2120 rear ends, shown in Fig. 4 B by the front end of end face 2120.
When lid 23 of the present utility model is assembled in casing 21, make the plate body 230 of lid 23 place the top of first guide member 211, second guide member 232 places the bottom of first guide member 211, and plate body 230 is moved toward the rear end of openings 22.Because the end face 2120 of two first fasteners 212 is provided with an inclined-plane 2121 to the inclination of the below of opening 22, the user imposes less strength just can make plate body 230 move to the front end of the end face 2120 of two first fasteners 212, contact the inclined-plane 2121 of the lower corner 2124 of two first fasteners 212, and then the convenient plate body 230 that promotes moves toward the rear end of end face 2120, second fastener 233 is combined with buckling piece 213, make lid 23 and casing 21 firm combining, as shown in Figure 5.Because the height of end face 2120 rear ends is identical with the height of existing end face 1121 shown in Fig. 2 B, therefore also can meet lid 23 and the casing 11 firm requirements that combine.
In the time will making lid 23 break away from casing 21, because the end face 2120 of first fastener 212 is provided with an inclined-plane 2121 to the inclination of the below of opening 22, make first fastener 212 than tool bendable folding endurance, and the upper end of first fastener 212 and plate body 230 have less contact area, therefore the user imposes less downward pressure lid 23 is moved toward the front end of openings 22, make second fastener 233 break away from buckling piece 213, and then make lid 23 break away from casing 21, more more laborsaving than the field-strip of above-mentioned existing snap fastener, convenient.
The end face 2120 of the utility model two first fasteners 212 all is provided with inclined-plane 2121, make plate body 230 place the top of first fastener 212, and make second fastener 233 buckle into snap action in the buckling piece 213, or make plate body 230 break away from first fastener 212, and make the assembling or the field-strip of second fastener, 233 disengaging buckling pieces 213 very easy.When needing dismounting and assembling lid 23 change printing coil paper, imposing the operation that less strength is promptly dismantled easily and assembled, plate body 230 being broken and the lid 23 that must more renew and cause waste.
The utility model snap fastener makes easier the assembling and field-strip between two members, more can not tear, damage fastening component because of the application of force is improper in assembling and unloading process and cause waste.
The above record only for utilizing the embodiment of the utility model technology contents, anyly is familiar with modification, the variation that this skill person uses the utility model to do, and all belongs to the claim that the utility model is advocated, and is not limited to that embodiment discloses.
