Abstract
The utility model discloses a novel universal joint, which comprises a left half joint, a right half joint and a cross axle, wherein the cross axle is provided with a dowel installation hole, a cylindrical pin installation hole and a center hole; the left half joint is connected with the cross axle after being put into the dowel installation hole by dowels; the right half joint is connected with the cross axle after being put into the dowel installation hole by a cylindrical pin; the top of one end of each dowel is provided with a bayonet; the middle of the cylindrical pin is provided with an annular groove along the outer circumferential surface; the two dowels are respectively put in from two ends of the dowel installation hole; and under the action of external force, the bayonets are deformed by the dowels to be fastened with the annular groove in the middle of the cylindrical pin. The novel universal joint disclosed by the utility model has the advantages of simple structure, reasonable design, convenience in installation, high strength and stable and reliable quality.
Description
Technical field
The utility model relates to a kind of connector, relates in particular to a kind of new-type Hooks coupling universal coupling.
Background technique
Hooks coupling universal coupling in the past, its pin that is used for fixing are through wearing a pin in the centre of sleeve, and the two ends of knocking pin are fixed its support greatly; And also often need punching in the centre of straight pin, so that pin passes from the centre, but the middle punching of straight pin has just reduced straight pin intensity; In addition, if too exert oneself through the fixing Hooks coupling universal coupling of sleeve before, make tension between half-coupling and the cross axle easily; Cause coupling dumb or stuck; Simultaneously, the as easy as rolling off a log loose or dislocation that causes pin of traditional Hooks coupling universal coupling causes damage and causes the production safety accident machinery.
Summary of the invention
In order to overcome the deficiency of existing technology, the utility model provide a kind of simple in structure, reasonable in design, easy for installation, intensity is high, the reliable new-type Hooks coupling universal coupling of steady quality.
The utility model solves the technological scheme that its technical problem adopted:
A kind of new-type Hooks coupling universal coupling; Comprise left half-coupling, right half-coupling and cross axle; Said cross axle is provided with pin mounting hole, straight pin mounting hole and intermediate hole, and said left half-coupling is connected with cross axle after inserting the pin mounting hole through pin, and said right half-coupling is connected with cross axle after inserting the straight pin mounting hole through straight pin; One end top of said pin is provided with bayonet socket; Middle part at said straight pin is provided with annular groove along outer peripheral surface, and said pin is two and inserts from the two ends of pin mounting hole respectively that said pin makes bayonet socket generation deformation and tightens together with the annular groove that is located at the straight pin middle part under the effect of external force.
The width of said bayonet socket is less than the diameter of annular groove, and the height of said bayonet socket will be equal to or greater than the radius of annular groove; On the annular groove at said straight pin middle part, also be provided with tongue and groove.
The beneficial effect of the utility model is: this product structure design is ingenious rationally to be provided with bayonet socket at an end top of said pin, is provided with annular groove at the middle part of said straight pin along outer peripheral surface; The straight pin of this product does not need punching; Improved the intensity of straight pin, secondly no longer need through sleeve realize pinning fixing, only need the pin on both sides be entered from the two ends hammering of pin mounting hole; When the bayonet socket of pin runs into straight pin, can support big by nature; The intermediate hole of cross axle provides suitable space to pin, and the pin nature is fixed, and can not withdraw from and come off.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the overall structure schematic representation of the utility model;
Fig. 2 is the combination schematic representation of cross axle, pin and straight pin;
Fig. 3 is the structural representation of pin and straight pin;
Fig. 4 is the sectional drawing along Fig. 2 B-B line;
Fig. 5 is the sectional drawing along Fig. 2 A-A line.
Embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5; A kind of new-type Hooks coupling universal coupling; Comprise left half-coupling 1, right half-coupling 2 and cross axle 3; Said cross axle 3 is provided with pin mounting hole 31, straight pin mounting hole 32 and intermediate hole 33, and said left half-coupling 14 is inserted pin mounting hole 31 back and is connected with cross axle 3 through pinning, and said right half-coupling 2 is inserted straight pin mounting hole 32 through straight pin 5 and then is connected with cross axle 3; One end top of said pin 4 is provided with bayonet socket 41; Middle part at said straight pin 5 is provided with annular groove 51 along outer peripheral surface, and said pin 4 is two and inserts from the two ends of pin mounting hole 31 respectively that said pin 4 makes bayonet socket 41 that deformation takes place and tightens together with the annular groove 51 that is located at straight pin 5 middle parts under the effect of external force.
As the optimization of above-mentioned mode of execution, the width of said bayonet socket 41 is less than the diameter of annular groove 51, and the height of said bayonet socket 41 will be equal to or greater than the radius of annular groove 51; On the annular groove 51 at said straight pin 5 middle parts, also be provided with tongue and groove, said tongue and groove be mainly used in prevent to pin 4 loosening, guarantee to pin 4 and straight pin 5 between be fastenedly connected.
This mechanism can prevent effectively that pin is loosening because of machine work causes, and straight pin do not need punching, has improved the intensity of straight pin; Secondly no longer need through sleeve realize pinning fixing; Only need the pin on both sides be entered from the two ends hammering of pin mounting hole, can the nature support when the bayonet socket on the pin runs into straight pin big, the intermediate hole of cross axle provides suitable space to pin; The pin nature is fixed, and can not withdraw from and come off.If too exert oneself through the fixing Hooks coupling universal coupling of sleeve before, make tension between half-coupling and the cross axle easily, cause coupling dumb or stuck; This mechanism can effectively solve above defective.
In the utility model, the material hardness that the bayonet part branch of said pin uses can not be too high, if too highly rupture when making the bayonet socket support big easily, causes and can not fix.
In addition, the utility model is not limited to above-mentioned mode of execution, needs only the technique effect that reaches the utility model with essentially identical means, all belongs to the protection domain of the utility model.
