Corner clasp

Technical field

The utility model relates to a kind of corner clasp.

Background technology

Existing highrise building, large kitchen are all provided with flue, and flue all adopt one save assembled, each joint flue be to be all cylinder or vertical bar shape.For the ease of the transportation of flue, existing flue employing is now flat polylith flue sheet mutually assembles and is spliced, and also some flue is to be mutually spliced by two L-type flue sheets.No matter adopt common flue sheet or adopt L-type flue sheet, when flue sheet splices mutually, two adjacent flue sheets need be connected and fixed, in case in use there is leaking cigarette phenomenon.

Summary of the invention

The purpose of this utility model is to provide a kind of corner clasp, can adjacent flue sheet member be buckled into firmly structure of integral body for the defect of existing flue sheet, to increase the intensity at assembling flue contact place; Simple and direct quick while thering is easy and simple to handle and dismounting.

The purpose of this utility model is achieved through the following technical solutions: a kind of corner clasp, it comprises elastic bend part, bending edge A and bending edge B, described bending edge A and bending edge B interconnect by elastic bend part, and the angle between bending edge A and bending edge B is less than 90 degree; One end away from elastic bend part of described bending edge A is provided with the Elastic buckle A that inside bending is stretched out, and one end away from elastic bend part of described bending edge B is provided with the Elastic buckle B that inside bending is stretched out.

On the medial surface of described bending edge A and bending edge B, be provided with several hangnails.

Described Elastic buckle A, and/or Elastic buckle B is segmental arc A, the segmental arc B along described segmental arc A to opposite direction bending comprising to described bend inner bending, forms a U-shaped groove between described segmental arc A and described segmental arc B, and, on described segmental arc B, offer through hole.

The radian of the U-shaped groove that described segmental arc A and segmental arc B connect into is 180 degree.

The material of described elastic bend part, bending edge A, bending edge B, segmental arc A, segmental arc B is metal, timber or plastics.

Compared to prior art, the utility model has the advantage of: corner clasp is pressed into two flexible junctions of flue sheet, utilizes the resilient clamp power forming between bend to fix, easy to use; Especially the end at bending edge has been provided with the U-shaped groove with through hole, facilitates the dismounting after corner clasp is installed.Simultaneously at bending edge A and bending edge B, be also all provided with hangnail, with further fixing to corner clasp.

Label declaration: 1 elastic bend part; 2 bending edge A; 3 bending edge B; 4 Elastic buckle A; 5 Elastic buckle B; 6 hangnails; 7 segmental arc A; 8 segmental arc B; 9 through holes; 10 draw-in grooves.

The specific embodiment

Below in conjunction with Figure of description and embodiment, the utility model content is elaborated:

Be illustrated in figure 1 the embodiment schematic diagram of a kind of corner clasp that the utility model provides, it comprises elastic bend part 1, bending edge A2 and bending edge B3, described bending edge A2 and bending edge B3 interconnect by elastic bend part 1, and the angle between bending edge A2 and bending edge B3 is less than 90 degree; One end away from elastic bend part 1 of described bending edge A2 is provided with the Elastic buckle A4 that inside bending is stretched out, and one end away from elastic bend part 1 of described bending edge B3 is provided with the Elastic buckle B5 that inside bending is stretched out.

On the medial surface of described bending edge A2 and bending edge B3, be provided with several hangnails 6.

As shown in Figures 2 and 3, described Elastic buckle A4, and/or, Elastic buckle B5 is segmental arc A7, the segmental arc B8 along described segmental arc A7 to opposite direction bending comprising to described bend inner bending, between described segmental arc A7 and described segmental arc B8, form a U-shaped groove, and, on described segmental arc B8, offer through hole 9.

The radian of the U-shaped groove that described segmental arc A7 and segmental arc B8 connect into is 180 degree.

The material of described elastic bend part 1, bending edge A2, bending edge B3, segmental arc A7, segmental arc B8 is metal, timber or plastics.

As Figure 4-Figure 6, corner described in the utility model clasp can be fixed for the splicing between flat flue sheet, L-type flue sheet, during use, first in the corresponding position, edge of the flue sheet that will splice, offer the draw-in groove 10 that supplies Elastic buckle A4 and Elastic buckle B5 to snap in, whole corner clasp correspondence is pressed into from the junction of two flue sheets, Elastic buckle A4 and Elastic buckle B5 in the clasp of corner are snapped in respectively in corresponding draw-in groove 10.After corner clasp snaps in, because the material of flue sheet is all harder, so can separately rap bending edge A2 and bending edge B3 with wooden mallet, hangnail 6 is thrust on flue sheet, further corner clasp is fixed on flue sheet.After installation, if want, corner clasp is disassembled, only need to insert in the through hole 9 on segmental arc B8 with a stiff rod, recycling lever principle is by Elastic buckle A4(or Elastic buckle B5) from draw-in groove, prize, opener dependence is low, no matter to the installation of corner clasp or dismantle, all fast and convenient.

As shown in Figure 7, the outer end of described Elastic buckle A4, and/or, the outer end indentation of Elastic buckle B5.Jagged end can increase the frictional force of Elastic buckle to draw-in groove 10, further prevents that Elastic buckle from ejecting from draw-in groove 10.
