Abstract
The utility model discloses a self-locking type claw hook which is composed of a clamp body, a clamp tongue and a reset spring, wherein the lower part of the clamp body is a connecting head, the upper part of the clamp body is in a semi-ring shape, and a passage in a semi-ring shape is arranged at the middle of the upper part in a semi-ring shape; the clamp tongue is a semi-ring shape and is arranged in the passage in a semi-ring shape, and the upper part of the clamp tongue is hinged with the upper end of the clamp body; one end of the reset spring is connected with the upper end of the clamp body, and the other end is connected with the upper part of the clamp tongue; the back side of the lower part of the clamp tongue is provided with a convex block which extends to an inner cavity of the connecting head of the clamp body and is bunted on the wall of the connecting head. The utility model has the characteristic of quick and firm connection, and is especially suitable for the connection of an aluminum scaffold.
Description
Technical field
The utility model belongs to the self-locking claw hook of building trade scaffold needling, hound joint area.
Background technology
The joint area of common scaffold bolt generally commonly used, nut connect parts on the building site, and this link is necessary tool using when installation or removal, spended time and labour, inefficiency.
Summary of the invention
The purpose of this utility model provides a kind of conveniently self-locking claw hook.
The purpose of this utility model is achieved in that it is made up of clamp, clip tongue and back-moving spring; The clamp bottom is a connector, and its top is the semi-ring shape, and semi-circular passage is set in the middle of the semi-ring shape on top; Clip tongue is the semi-ring shape, and clip tongue places semi-ring shape passage, and its top and clamp upper end are hinged; Back-moving spring one end is connected with the clamp upper end, and the back-moving spring other end is connected with clip tongue top, and projection is established at the back side, clip tongue bottom, and projection is stretched the connector inner chamber of putting at clamp and is against Qi Bishang.
The utility model is because under the effect of back-moving spring, and the clip tongue lower end that places clamp is tilting up and down, and it is not only quick but also firmly that it is connected, and do not need instrument, increases work efficiency, and is particularly useful for the connection of aluminium extruded sections scaffold.

Among the figure: clamp 1 clip tongue 2 back-moving springs 3 connectors 4 semi-ring shape passages 5 pins 6 projections 7
The specific embodiment
With reference to Fig. 1, present embodiment is made up of clamp 1, clip tongue 2 and back-moving spring 3.Clamp 1 bottom is a connector 4, connector 4 is the pipe shape, and clamp 1 top is the semi-ring shape, and semi-circular passage 5 is set in the middle of the semi-ring shape on top, the semi-ring shape on clamp 1 top can be by two semi-circular shape jig arm, and semi-circular passage 5 is to be made of the space between the two semi-circular shape jig arm.Clip tongue 2 is the semi-ring shape, clip tongue 2 places semi-circular passage 5, also be to place between the two semi-circular shape jig arm, the upper surface of clip tongue 2 bottoms upwarps the upper surface that exceeds two semi-circular shape jig arm bottoms, and clip tongue 2 tops are connected with clamp 1 upper end (two semi-circular shape jig arm) by pin 6.Back-moving spring 3 is around the home on pin 6, back-moving spring 7 one ends are connected with clamp 1 upper end (two semi-circular shape jig arm), and back-moving spring 3 other ends are connected with clip tongue 2 tops, and projection 7 is established at the back side, clip tongue 2 bottom, projection 7 is stretched and is put in the connector 4 of clamp, and inconsistent with the tube wall of connector 4.The external diameter of connector 4 top pipes is bigger than the external diameter of its underpart pipe, the external diameter of needling and hound is identical with connector 4 top pipes, connector 4 bottom pipes insert in needling or the hound, with the joint welding of needling or hound and connector 4 top pipes.When the self-locking claw hook is connected with cross bar, cross bar is pushed away in clamp, cross bar is depressed the clip tongue lower end that upwarps, after cross bar enters clamp, under the effect of back-moving spring, upspring in the clip tongue lower end, recovers the state that upwarps, its projection is conflicted on the tube wall of connector, make the self-locking claw hook tightly hook embrace cross bar.
