Description
Technical field
A kind of article-storage device is the utility model is related to, more specifically, it relates to a kind of case and bag.
Background technology
Edge cover strip is provided with the edge of case and bag, the edge of case and bag is protected by edge cover strip.Edge cover strip sews
On boxboard, for make edge cover strip have preferable intensity, edge cover strip generally use sandwich construction, but the edge cover strip of sandwich construction with
The suture of boxboard is difficult and edge cover strip on boxboard easily by coming off.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of edge cover strip case difficult for drop-off
Bag.
To achieve the above object, the utility model provides following technical scheme：A kind of case and bag, including casing and bound edge
Bar, casing include backplate, it is characterised in that：The edge cover strip includes the first elastic strip, the soft bar and second being sequentially connected
Elastic strip, soft bar are wrapped in the avris of backplate, and the first elastic strip and the second elastic strip are located on the side of backplate respectively,
Clamping projection is equipped with the two sides of backplate, is equipped with the first elastic strip and the second elastic strip and matches somebody with somebody with clamping projection interference
The buckling groove of conjunction, the side wall of the buckling groove are provided with preformed groove, and the opening of preformed groove extends to clamping by the bottom land of buckling groove
The notch of groove, the side wall of the preformed groove is in arcuation, and the radian of reserved groove sidewall is 120 °~180 °, backplate by endothelium,
Crust and the boxboard being placed between endothelium and crust are formed, and the soft bar inwall is provided with the bar shaped that shaft section is triangle
Teeth, the bar shaped teeth centre are provided with groove.
By using above-mentioned technical proposal, the more soft plastics of soft strip adoption are made, the first elastic strip and the second bullet
Property strip adoption elasticity preferably plastics be made, such as styrene series thermoplastic elastomer；Boxboard is preferably made of ABS plastic.
During edge cover strip is wrapped in into backplate avris, the first elastic strip and the second elastic strip are extruded so that clamping projection is entered
Enter in buckling groove, and cause clamping raised and buckling groove interference fit, sutured afterwards by edge cover strip and boxboard；It is convex by clamping
The cooperation with buckling groove is played, buckling groove deformation produces elastic-restoring force, and the elastic-restoring force of buckling groove is acted in clamping projection,
So that edge cover strip is not easy to be come off by boxboard, during clamping projection is squeezed into buckling groove, clamping projection is to preformed groove and card
The intersection of access slot produces extruding so that is opened to both sides the intersection of preformed groove and buckling groove so that the cross section of buckling groove
Area increases, and so as to which the raised energy of clamping is more convenient, labour-saving is added in buckling groove, clamping projection is being squeezed into the mistake of buckling groove
Two intersections of Cheng Zhong, preformed groove and buckling groove are extruded by clamping projection so that and reserved groove sidewall produces flexural deformation,
Deflection caused by two intersections of preformed groove and buckling groove is essentially identical；When the radian of reserved groove sidewall less than 120 ° when
Wait, because radian is larger, preformed groove center produces larger hollow area in actual engagement process, is not easy to connect, when
When the radian of reserved groove sidewall is 160 °, preformed groove can produce more normal deformation, and elastic resilience is preferable, not allow to take off
Fall, when the radian of reserved groove sidewall is more than 180, deformation drag caused by preformed groove is larger, it is not easy to clamping, and soft bar
Inwall is provided with the bar shaped teeth that shaft section is triangle, is provided with groove among the bar shaped teeth, the soft bar inwall is formed
One piece one piece of tooth so that soft bar can extrude using to natural resiliency, outer with extruding progress biting well
Skin.

Embodiment
The utility model embodiment is described further referring to figs. 1 to Fig. 5.
A kind of case and bag, including casing 9 and edge cover strip 1, casing 9 include backplate, it is characterised in that：The edge cover strip 1 wraps
The first elastic strip 3 being sequentially connected, the elastic strip 5 of soft bar 4 and second are included, soft bar 4 is wrapped in the avris of backplate, the first bullet
Property bar 3 and second elastic strip 5 respectively on the side of backplate, clamping projection 6 is equipped with the two sides of backplate, first
The buckling groove 7 with the interference fit of clamping projection 6 is equipped with the elastic strip 5 of elastic strip 3 and second, in the side wall of the buckling groove 7
Provided with preformed groove 8, the opening of preformed groove 8 is extended to the notch of buckling groove 7, the side wall of the preformed groove 8 by the bottom land of buckling groove 7
In arcuation, and the radian of the side wall of preformed groove 8 is 120 °~180 °, and backplate is by endothelium 21, crust 22 and is placed in the and of endothelium 21
Boxboard 2 between crust 22 is formed, and the soft inwall of bar 4 is provided with the bar shaped teeth 41 that shaft section is triangle, the bar
Groove 42 is provided among shape teeth 41.
By using above-mentioned technical proposal, soft bar 4 is made of more soft plastics, the first elastic strip 3 and second
Elastic strip 5 is made of elasticity preferably plastics, such as styrene series thermoplastic elastomer；Boxboard 2 preferably uses ABS plastic system
Into.During edge cover strip 1 is wrapped in into backplate avris, the first elastic strip 3 and the second elastic strip 5 are extruded so that clamping
Projection 6 enters in buckling groove 7, and clamping projection 6 is interference fitted with buckling groove 7, is stitched afterwards by edge cover strip 1 and boxboard 2
Close；By clamping projection 6 and the cooperation of buckling groove 7, the deformation of buckling groove 7 produces elastic-restoring force, the elastic-restoring force of buckling groove 7
Act in clamping projection 6 so that edge cover strip 1 is not easy to be come off by boxboard 2, and clamping projection 6 is being squeezed into the process of buckling groove 7
In, the intersection of the raised 6 pairs of preformed grooves 8 of clamping and buckling groove 7 produces extruding so that the intersection of preformed groove 8 and buckling groove 7 to
Open on both sides so that the cross-sectional area increase of buckling groove 7, so as to which the energy of clamping projection 6 is more convenient, labour-saving adds buckling groove
In 7, during clamping projection 6 is squeezed into buckling groove 7, two intersections of preformed groove 8 and buckling groove 7 are raised by clamping
6 extruding so that the side wall of preformed groove 8 produces flexural deformation, preformed groove 8 and deflection caused by two intersections of buckling groove 7
It is essentially identical；When the radian of the side wall of preformed groove 8 is less than 120 °, because radian is larger, reserved in actual engagement process
The center of groove 8 produces larger hollow area, is not easy to connect, and when the radian of the side wall of preformed groove 8 is 160 °, preformed groove 8 can
To produce more normal deformation, elastic resilience is preferable, does not allow to come off, when the radian of the side wall of preformed groove 8 is more than 180, in advance
Stay deformation drag caused by groove 8 larger, it is not easy to clamping, and the inwall of soft bar 4 is provided with the bar shaped that shaft section is triangle
Teeth 41, the centre of bar shaped teeth 41 are provided with groove 42, and the soft inwall of bar 4 forms one piece one piece of tooth so that soft bar 4
It can be extruded using to natural resiliency, carry out good biting crust 22 with the extruding.
Preferred embodiment of the present utility model is the foregoing is only, not limiting the utility model, the skill of this area
Art personnel carry out common variations and alternatives in the range of technical solutions of the utility model should all be included in guarantor of the present utility model
