Description
Technical Field
The utility model relates to a fastener technical field, in particular to gecko is compeled in convenient to assembly.
Background
In the fields of concrete, compact natural stone, metal structures, metal profiles, bottom plates, supporting plates, brackets, railings, windows and the like, a plurality of parts are difficult to fix due to the difficulty in tapping threaded holes, the common usage is that a hole is drilled first, then a car gecko is installed in the hole, the expansion of an expansion sleeve of the car gecko is utilized to extrude and fix the hole wall, and then an expansion head with threads in the expansion sleeve is utilized to realize the effect of threaded connection with other objects; in the existing internal forced gecko, the structure is complex and is not easy to assemble.
SUMMERY OF THE UTILITY MODEL
To the deficiency that prior art exists, the utility model provides an interior gecko of compelling convenient to assembly.
In order to achieve the above purpose, the utility model provides a following technical scheme: an interior forced gecko convenient to assemble, characterized by: including expansion tube, expansion head, sleeve, connecting rod, horizontal pole and montant, be equipped with on the montant with horizontal pole one end complex mating holes, horizontal pole one end is interference fit with the mating holes, horizontal pole other end threaded connection has the connecting rod, the one end that the horizontal pole was kept away from to the connecting rod is equipped with the external screw thread, external screw thread department is connected with the sleeve, set up the helping hand ring in the sleeve, be equipped with the big fender ring of diameter ratio sleeve on the connecting rod, the top is in helping hand ring department when expansion tube uses, expansion head one end is equipped with the toper face, be equipped with evenly distributed's the line of turning only on the toper face, be equipped with a breach of seting up along its generating line direction on the expansion tube, breach one end is equipped with circular opening, be equipped with in the expansion tube with the line of turning only complex groove of turning.
Adopt above-mentioned technical scheme, during the external screw thread of inflation head connecting rod during use and the screw-thread fit in the inflation head, the inflation head can receive the effect upward movement of power, in the same direction as taking expansion sleeve also can be upward movement together, after inflation head embedding expansion sleeve, the spline line on the conical surface of inflation head can cooperate with the spline groove of setting on the expansion sleeve inside wall, reach and prevent the inflation head at the intraductal pivoted effect of inflation sleeve, make inflation head more stable with expansion sleeve's cooperation, withstand the helping hand ring that sets up in the sleeve when expansion sleeve upward movement, the connecting rod turns to again this moment, the inflation head will be absorbed in and prop open expansion sleeve in the expansion sleeve, high durability and convenient use, cooperation through horizontal pole and montant, make things convenient for the application of force with horizontal pole one end and connecting rod threaded connection again, high durability and convenient use, and easy assembly.
The utility model discloses further set up to: concave patterns are uniformly arranged on the outer surface of the expansion sleeve around the split.
By adopting the technical scheme, the concave patterns enhance the friction force between the expansion sleeve and a fastening object in the expansion process of the expansion sleeve, and the connection strength is ensured.
The novel beneficial effect of this experiment does: convenient to use and easy assembly.
The present invention will be further described with reference to the accompanying drawings.
