Abstract
The clamping device for scaffold pipe fitting has one outer casing with conic hole in the inner cavity. The inner part of the outer sleeve is provided with a fastening sleeve, the outer part of the fastening sleeve is a cylinder with a small upper part and a big lower part, the fastening sleeve is matched with a conical hole of the inner cavity of the outer sleeve, the inner cavity of the fastening sleeve is a cylindrical hole, the upper part of the cylindrical hole is provided with a tooth socket, and the upper part of the fastening sleeve is provided with a longitudinal cutting groove. The vertical steel pipe of the scaffold is arranged in the cylindrical hole in the inner cavity of the fastening sleeve. The outer edge of the outer sleeve is connected with an ear, the outer edge of the ear is provided with a transverse sunken semi-cylindrical surface, the lower part of the ear is provided with a pin hole, and a gland with an inner cylindrical surface is connected through a pin. The upper part of the lug is also provided with a pin hole which is connected with a movable pull rod through a pin, and the other end of the movable pull rod penetrates through the gland and is tightly held by a nut to form the hoop. The horizontal steel pipe of the scaffold is arranged in the hoop of the gland. The clamping device of the scaffold pipe fitting has the advantages that the bearing capacity is twice of that of an original bolt structure, and the clamping device is convenient to use.
Description
Affiliated technical field
The utility model is applicable to the scaffold equipment that building operations is used.
Background technology
The chucking of existing scaffold pipe fitting is to use bolton merely, and its weak point is, the chucking of this structure is little to the bearing capacity of scaffold pipe fitting, and installation and removal are inconvenient.
The utility model content
The purpose of this utility model is the gripping mechanism that a kind of scaffold pipe fitting is provided in order to overcome above-mentioned weak point, and is big to the bearing capacity of scaffold pipe fitting, and installation and removal are convenient.
The technical scheme that its technical problem that solves the utility model adopts is: the utility model device has an overcoat, at the inner chamber of overcoat up-small and down-big conical bore is arranged.There is adapter sleeve inside at overcoat, and the outside of adapter sleeve is that the conical bore of the inner chamber of up-small and down-big cylinder and overcoat matches, and the inner chamber of adapter sleeve is a cylindrical hole, on the top of cylindrical hole teeth groove is arranged.Be provided with the vertical grooving in 3-8 road on the top of adapter sleeve.The vertical steel pipe of scaffold just places in the cylindrical hole of adapter sleeve inner chamber.Outer rim at overcoat is connected with the ears or side handles of a utensil, and the hemicycle cylinder in that the outer rim of the ears or side handles of a utensil has horizontal depression has pin-and-hole in the bottom of the ears or side handles of a utensil, and by the pin connection is the gland with half inner cylinder face.On the top of the ears or side handles of a utensil pin-and-hole is arranged also, connect active pull rod by pin, the other end of active pull rod passes gland, and holds tightly with nut, to form anchor ear.The horizontal steel pipe of scaffold just places in the anchor ear of gland.
Effective effect of the present utility model is, uses the gripping mechanism of this scaffold pipe fitting, and bearing capacity is the twice of former bolt arrangement, uses also very convenient.
Description of drawings
Figure is the structure chart of the gripping mechanism of scaffold pipe fitting of the present utility model.1-pin among the figure, 2-gland, 3-active pull rod, 4-pin, the 5-ears or side handles of a utensil, the vertical grooving of 6-, 7-adapter sleeve, 8-overcoat, 9-teeth groove.
Specific implementation method
The utility model device has an overcoat (8), at the inner chamber of overcoat (8) up-small and down-big conical bore is arranged, and its conicity is 85 degree.In the inside of overcoat (8) adapter sleeve (7) is arranged, the outside of adapter sleeve (7) is up-small and down-big cylinder, and the conical bore of the inner chamber of overcoat (8) matches, and conicity also is to be 85 degree, the inner chamber of adapter sleeve (7) is a cylindrical hole, and the internal diameter of cylindrical hole is that the external diameter of steel pipe strengthens the 1-5 millimeter again.Teeth groove (9) is arranged on the top of cylindrical hole, and the degree of depth of teeth groove is 4 millimeters.Be provided with the vertical groovings in 4 roads (6) on the top of adapter sleeve (7).The width of grooving (6) is 3 millimeters.The vertical steel pipe of scaffold just places in the cylindrical hole of adapter sleeve (7) inner chamber.Outer rim at overcoat (8) is connected with the ears or side handles of a utensil (5), and the hemicycle cylinder in that the outer rim of the ears or side handles of a utensil (5) has horizontal depression has pin-and-hole in the bottom of the ears or side handles of a utensil (5), and by pin (1) connection is the gland (2) with half inner cylinder face.On the top of the ears or side handles of a utensil (5) pin-and-hole is arranged also, connect active pull rod (3) by pin (4), the other end of active pull rod (3) passes gland (2), and holds tightly with nut, to form anchor ear.The horizontal steel pipe of scaffold just places in the anchor ear of gland.
Claims (2)
