Abstract

The utility model relates to a scissors type fixing device which belongs to the class of machines and tools, and is suitable for mounting and fixing objects on concrete faces and the facilities in the open air such as permanent marks, semi-permanent marks, etc. The utility model is composed of a flat bar and a scissors type fixing sheet. The scissors type fixing sheet is fixed on the tail section of the flat bar, and when the scissors type fixing sheet is under stress to expand outwards, the concrete or the earth can be clamped by the scissors type fixing sheet. The utility model provides a fixing device which has the advantages of easy use, firm fixation, and accurate positioning.

Description

Scissors type fixed device

The utility model belongs to the facility class.

The scissors fixing device is applicable to and installs and fixes object on concrete surface, also is applicable to installing and fixing of facilities such as in the open air permanent, semipermanent sign.

At present, the fixing device that the object employing is installed on concrete surface has foot screw, expansion set screw, cement nail etc., exist shortcomings such as using inconvenience, expansion set screw, cement nail can't be fixed bigger object, when using, stone bolt needs earlier concrete to be excavated, again lay concrete after placing again, and be difficult for accurately location.

The purpose of this utility model is in order to provide a kind of scissors fixing device of easy to use, fixation, accurate positioning.

The scissors fixing device is made up of scissors fixed plate (4,5), flat bar (2) and pin (3,6) etc., scissors fixed plate (4,5) is installed on two wide planes of flat bar (2) respectively by pin (6), pin (3) makes the ogival of scissors fixed plate (4,5) upper end stretch out flat bar (2) certain distance, produce eccentric action of gravity, thereby scissors fixed plate (4,5) can be rotated to the outside of the side of flat bar (2) around pin (6) automatically.

The angle of top tip part by formed its upper end of two seamed edges of scissors fixed plate (4,5) is 30～45 °.

The bottom of flat bar (2) becomes sharp type, and flat bar (2) can be inserted in mounting hole or the soil easily.

For the ease of using in multiple occasion, the upper end of flat bar (2) can be made into bolt (1), hook (7), sleeve (8) and riffled tube (9) etc.

Accompanying drawing 1 is the direct-view figure of scissors fixing device.

Accompanying drawing 2 is left side views of scissors fixing device.

Accompanying drawing 3 is broken section enlarged views of scissors fixing device.

Accompanying drawing the 4,5, the 6th, the flat bar upper end schematic representation of scissors fixing device.

Accompanying drawing 7 is working state schematic representations of scissors fixing device.

The utility model will be further described below in conjunction with accompanying drawing:

As accompanying drawing 7, when the scissors fixing device installs and fixes object on concrete surface, only need on concrete, to bore a hole, the diameter in hole is bigger slightly than two of scissors fixed plate (4,5) top distances, the scissors fixing device is inserted, then with sleeve or bar with scissors fixed plate (4,5) to pressing down, it is opened, block the concrete layer bottom, concrete is injected in last gap between hole wall and flat bar.

When in thicker concrete layer, using the utility model, firmly make scissors fixed plate (4,5) snap in concrete wall a little, also can finish fixing task.

In earth, use the scissors fixing device, only need be inserted into or knock in the earth and get final product.
