Abstract

The utility model relates to an integral clamp without a torsion spring. The upper clamping sheet (11) and the lower clamping sheet (12) of the tail part of the utility model are connected into an integral clamp by a V-shaped connection sheet (13). The middle part of the upper clamping sheet (11) of the clamp is provided with a combination sheet (16) which is provided with a convex shaft (16). Both sides of the middle part of the lower clamping sheet are each provided with side combination sheets (17) which are provided with circular holes (19). The convex shaft (18) is matched with the circular hole (19). The convex shaft is embedded on the back part of the circular hole. The upper clamping sheet and the lower clamping sheet are connected into integration. The convex shaft and the circular hole are combined into a rotating shaft center. The V-shaped connection sheet does the action of a spring. Because the clamp of the design eliminates the traditional connection mode of the torsion spring of the clamp as well as is made once in the integral mode, the utility model saves the material and the time and extends the service life.

Description

Integral clamp without torsion spring

The utility model relates to the clip of articles for daily use, refers in particular to a kind of no torsion spring global formation clip.

The clip that torque spring is housed in the middle of two intermediate plates up and down is widely used in the daily life, for example the document folder used of clip on the drying rack and office etc.The clip that this kind tradition is used has two significant defectives, and the first is buckled in rotating shaft with wire spring and makes its connection and produce elastic force in two intermediate plates up and down, and therefore the rotating shaft of plastic grip in use is easy to be damaged by the metal torsion spring; Its two in manufacture process must with manually two intermediate plates with the assembling of metal torsion spring, the consumption worker is more.

First purpose of the present utility model is at above-mentioned defective, proposes a kind of brand-new design, and traditional torsion spring has been removed in this design, has therefore eliminated the defective of metal torsion spring damage plastics rotating shafts, has prolonged the life-span of clip; Another purpose of the design is on the basis of removing torsion spring, proposes a kind of clip of global formation, saves significantly and assembles man-hour.

The technical solution of the utility model is to establish a V-type connecting sheet at the afterbody of two intermediate plates up and down two intermediate plates are connected into an integral body, a middle bonding pad with protruding axle is established in the centre of upper clip, and lower clamping piece respectively has a side bonding pad with holes with respect to the both sides of the position of bonding pad in the upper clip.The protruding axle of bonding pad in the upper clip is flush-mounted in the hole of lower clamping piece side bonding pad, two intermediate plates can be relatively rotated, the V-type connecting sheet of afterbody then has the effect of elastic force, has replaced original spring.Therefore the design's clip has not only saved torsion spring but also can make of plastic monoblock.

Details are as follows in conjunction with the accompanying drawings for the utility model, wherein:

Fig. 1 is no torsion spring global formation clip schematic perspective view;

Fig. 2 is the side view of no torsion spring global formation clip;

Fig. 3 is the A-A portion face of Fig. 2;

Fig. 4 is for installing ringed clip schematic representation.

As Figure 1-3, the described clip of the design has a upper clip (11) and a lower clamping piece (12), and the tail end of upper clip and lower clamping piece has a V-type connecting sheet (13) that concaves that upper and lower two intermediate plates are linked to be an integral body.Extend a middle joint fastener (16) in upper clip (11) center, respectively there is a protruding axle (18) on the both sides of bonding pad in this (16); Respectively there is a side bonding pad (17) both sides at lower clamping piece (12) middle part with respect to middle bonding pad (16) position, the centre of two side bonding pads (17) is a space (20) for bonding pad (16) in installing, and the circular hole (19) that respectively has a protruding axle (18) with middle bonding pad (16) to be complementary on the above-mentioned side engagement sheet (17), behind protruding axle (18) insertion circular hole (19), two intermediate plates combine up and down, and two intermediate plates can relatively rotate up and down.The afterbody outer surface of upper and lower two intermediate plates (11) and (12) can be plane tabular (as shown in the figure), also can be designed to the arcuation (not shown).On the afterbody outer surface of upper and lower intermediate plate, can be provided with embossing portion (31) and (32), to increase friction, easy to use.Upper and lower two intermediate plates (11) and (12) afterbody inner face respectively have a connecting plate (14) and (15) to be connected with (17) are curved with the joint fastener of two intermediate plates (16) up and down respectively; And the tail end of two intermediate plates has a V-type connecting plate (13) up and down, forms the activity space (30) of V-type connecting plate (13) between V-type plate (13) and connecting plate (14) and (15).The front end outer surface of last lower clamping piece (11) and (12) can be plane tabular (as shown in the figure) also can be designed to the arcuation (not shown); The inner face of front end is followed successively by chamfering (23) and (24) after by forward direction as shown in Figure 2, embossing portion (25) and (26), by semicircle orifice (27) and (28), connecting part, plane (21) and (22) are made up and are formed zigzag fashion (being three circular holes and three staggered combinations in planes among the figure), are convenient to clamp clothing.Because above-mentioned structure, push embossing portion (31) and (32) of two intermediate plate tail ends in use, then two intermediate plates are the rotating shaft center with protruding axle (18) up and down, clip front end embossing portion (25) and (26) and joining portion (21) and (22) are opened, and the both wings of V-type connecting sheet (13) are pressed superimposed; When unclamping the pressure of embossing portion (31) and (32), the both wings of V-type connecting sheet reset, the combination once more of the front end of clip, and clothing is clamped in embossing portion (25) and (26) and joining portion (21) and (22) combination once more.In order to strengthen the intensity of clip, can also between the surface plate of last lower clamping piece (11) and (12) and bonding pad, suitably add and help (not shown).

Fig. 4 is illustrated in two intermediate plates up and down (11) of the design's clip and the afterbody of (12) respectively stretches out a little flange (35) and (36), and has aperture (37) and (38) on flange.Utilize aperture (37) and (38) can seal in an annulus (39), can be hung on clip on the various drying rack like this.

Therefore the design's clip has not only been eliminated the metal torsion spring of traditional clip, and since the V-type connecting sheet two intermediate plates are up and down fused, therefore can an injection moulding, global formation, save the cost of raw material and installation work-hour significantly, can also prolong the working life of clip.
