Abstract

The utility model relates to a plate buckling mechanism. A corresponding positioning hole is arranged between a first plate and a second plate and inserting a sleeve of fixing component into the positioning hole of the first plate with a sleeve hole running through the center of the sleeve. On the front side of the sleeve is provided with an opening groove and forms many expansion mouths on the front side of the sleeve. A protruding rib is arranged inside wall of the several expansion mouths and forms an opening mouth at the center of many protruding ribs and the buckling component connected with the second plate is inserted into the sleeve holes; the buckling body of the buckling component inserts to the opening hole which pushes the protruding rob so as to expand the expansion blade and enable the fixing component to insert in to the positioning hole of the first plate. Therefore, the utility model will integrate the two plates as whole compactly.

Description

The sheet material fastening structure

Technical field

The utility model is relevant for a kind of sheet material fastening structure, refers to a kind of making between sheet material in conjunction with more firm sheet material fastening structure closely especially.

Background technique

Office furniture, composite furniture all can be used plate body, and for two plate bodys being mutually combined or reserving a space, regular meeting's utilization fastening structure mutually combines two plate bodys.

As shown in Figures 1 and 2, be general buckling member 5, it comprises a clamp ring 51 and a clamping connection body 52, this clamp ring 51 mainly comprises ring bodies 511 and outwards outstanding lug 512, ring bodies 511 inner edges slope inwardly and are provided with a plurality of protruding sour jujubes 513, and clamping connection body 52 has a base 521 and by base 521 upwardly extending protruded stigmas 522, at first earlier clamp ring 51 is pegged lug 512 with ㄇ font blind rivet 53 and be fixed in the positioning hole 541 of second sheet material 54, and protruding sour jujube 513 is towards the rear of second sheet material 54, then, clamping connection body 52 passed the open-work 551 of first sheet material 55 and aim at the center of clamp ring 51 and embed, the protruded stigma 522 that utilizes protruding sour jujube 513 to be resisted against clamping connection body 52 stops clamping connection body 52 to break away from, and then first sheet material 55 and second sheet material 54 are fixed, each plate body is provided with position, hole relative open-work 551 and positioning hole 541 mutually.

Yet, for the protruding sour jujube 513 that makes clamp ring 51 is an inclination, the positioning hole 541 that then embeds clamp ring 51 will remove more volume, add on second sheet material 54 and will be provided with a plurality of positioning holes 541, then easily cause plate body structure intensity to weaken, even generation crackle, moreover the element of known structure is more, causes consumption worker problem consuming time, and installing blind rivet 53 is caused danger easily, after clamp ring 51 was fixed in second sheet material 54 again, the 52 essential accurately contrapositions of clamping connection body embedded clamp ring 51, in case the Kong Weiwu alignment, then must repair the hole adjustment again, more increase the waste in man-hour.

So, the inventor is because the disappearance of above-mentioned general buckling member, be that research and development are founded one and can be pulled the material fastening structure for what solve that above-mentioned fraud loses, see also " the sheet material fastening structure " of Chinese application number 200520133000.5, it comprises: one has the pilum of holding part and gripping section, these gripping section two ends are respectively established one first clamp face and one second clamp face and are formed grasping part, first clamp face is by being surrounded on pilum and having first end and the banded plate body of second end is constituted, first end of banded plate body folds angle formation breach with second end, holding part be provided be spaced and around the ring-type plate body; Breach by first clamp face tilts an angle to screw in the open-work on one first sheet material, make first sheet material be embedded into grasping part, embed a positioning hole of one second sheet material again with the holding part front end, the outer rim of ring-type plate body is slightly larger than the positioning hole inner edge, prop up a positioning hole hole ancient piece of jade, round, flat and with a hole in its centre by the external edge of annular plate, so that first sheet material and second sheet material are fixed.

Though this sheet material fastening structure can solve the not positive problem in assembly hole position between sheet material, and increase efficiency of construction; So, when because of factor such as construction flaw etc., buckling member must be detached when taking out the sheet material positioning hole, often cause the damage of this sheet material positioning hole and the damage of buckling member ring-type plate body, in this, even more renew buckling member, the positioning hole that this former sheet material has been damaged, also can't do good assembling, and make sheet material must do to scrap processing, cause the loss on manufacturer's cost with buckling member.

Summary of the invention

The purpose of this utility model is to provide a kind of sheet material fastening structure, to solve the problem that existing structure exists.

The purpose of this utility model is to realize like this, a kind of sheet material fastening structure, in the positioning hole of sheet material, be arranged with fixed block, this fixed block is provided with a sleeve, run through trepanning in described sleeve center, opened groove in this sleeve front side again, the sleeve front side forms a plurality of expanding plates, connect the tool fin in described a plurality of expanding plate inwalls, and in a plurality of fins, be formed centrally a perforate; Design thus, when placing buckling member in the trepanning of fixed block, this buckling member promptly can strut expanding plate, and makes its ring-type plate body of buckling member and fin fasten the location mutually, expanding plate is packed in the positioning hole of sheet material, to fix.

The expanding plate outer wall of this fixed block is provided with the reinforced ribs that increases sleeve and positioning hole packing degree.

The trepanning entry end port of this fixed block is provided with in order to buckling member and aligns the lead angle that is inserted in the trepanning centralized positioning.

The sleeve rear end of this fixed block even has stop edge.

It is taper that the trepanning of this fixed block is tool.

The cover hole wall of this fixed block is provided with the rib that fastens the location for the ring-type plate body of buckling member mutually.

From the above, the utlity model has following advantage:

1. the utility model mainly is to be the intermediary element that fixed block with a plurality of expanding plates is established as group between sheet material and buckling member by a front side, thus, can when buckling member is planted into fixed block, make expanding plate strut the positioning hole that packing is sticked in sheet material, more increase the steadiness of assembling.

The utility model mainly be by a fixed block as the group intermediary element of establishing between sheet material and buckling member, thus, factors such as flaw in construction, and buckling member must be detached the sheet material positioning hole time unlikelyly directly cause damage to the sheet material positioning hole.

3. the utility model is established lead angle in the trepanning entry end tool of fixed block, aligns fast in the trepanning that imports fixed block in order to buckling member, more increases the effect of buckling member assembling location.

4. the utility model makes the sleeve front side tool of fixed block establish a plurality of flutings, makes the sleeve front side form several expanding plates, establishes several reinforced ribs in each expanding plate outer wall tool again; In this, not only can increase the packing degree between expanding plate and sheet material positioning hole, and can increase the sheet material applicability of fixed block different aperture settings hole.
