Abstract
The utility model relates to a detachable hinge pin connecting structure used for pipe connection. The detachable hinge pin connecting structure comprises a pin, a male connector and a female connector matched with the male connector, wherein the male connector and the female connector are respectively provided with a pin hole used for inserting the pin, and at least one face contact exists on the portions, making contact with the pin holes, of the pin. The detachable hinge pin connecting structure used for pipe connection can reduce contact stress.
Description
Technical field
The utility model belongs to mechanical field, relates to a kind of mechanical linkages structure, relates in particular to a kind of for managing the removable pin Axile connection structure of connection.
Background technique
Bearing pin connects due to simple in structure, easy to operate and change the advantages such as easy, very extensive in the application in machinery, building, water conservancy project field.Conventionally the pin joint structure adopting as shown in Figure 1, is made up of negative joint, male connector, round pin three parts, yin, yang joint respectively with steel-pipe welding, two joints connect by round pin.
The pin joint structure using at present, in the time transmitting larger longitudinal loading, there will be following problem:
1, for the ease of mounting or dismounting, the radius of pin-and-hole is greater than the diameter of round pin, can cause like this pin to contact with pin-and-hole top-stitching, even contact (referring to Fig. 2), in the time that the longitudinal loading of transmitting is larger, can produce very high contact stress at contact area, in the time that contact stress is enough large, will produce adhesion or seam at point of contact, and cut off or torn in relative tangential motion, cause material transfer or peel off gradually, causing adhesive wear, jeopardizing the safety of mechanical structure.
2, volume is excessive.Round pin composite bending modulus is less, thereby for meeting the intensity of round pin, it is very large that round pin diameter usually will be obtained, and excessive round pin diameter can weaken the intensity of yin, yang joint greatly, and for meeting join strength requirement, it is very large that size just need to be got, and waste material is uneconomical.
Model utility content
In order to solve the above-mentioned technical problem existing in background technique, the utility model provide a kind of reduce contact stress for managing the removable pin Axile connection structure of connection.
Technical solution of the present utility model is: the utility model provides a kind of for managing the removable pin Axile connection structure of connection, comprise pin, male connector and with the suitable negative joint of male connector; On described male connector and negative joint, be provided with the pin-and-hole inserting for pin, its special way is: the position that described pin contacts with pin-and-hole at least exists a face to contact.
The cross section of above-mentioned pin-and-hole and pin surface of contact is circular arc type.
The radius of arc of above-mentioned pin is identical with the radius of arc of pin-and-hole.
Above-mentioned pin is cylindrical peg or cotter pilotage.
The utility model has the advantages that:
Pin joint structure of the present utility model adopts the cotter pilotage that composite bending modulus is larger to connect, thereby the diameter of pin can design littlely, reduced the weakening to pin-and-hole, thereby yin, yang joint also can do littlely, effectively reduce the volume of linkage structure, reduced the waste of material.The second, the radius of cotter pilotage is identical with pin-and-hole, thereby in the time transmitting the longitudinal force of both direction, is face contact between pin, hole, reduces contact stress.The 3rd, owing to all having gap between pin, hole on aspect length and width, thereby be convenient to handling.The 4th, the utility model can be under the prerequisite of radius that does not change hole, by changing the length of cotter pilotage, adjust its composite bending modulus, the intensity of linkage structure is more reached unanimity, realize the equal strength design connecting, cross-sectional dimension and material can be adjusted as required, to meet larger longitudinal loading requirement.The utility model adopts cotter pilotage to connect, and all stay certain gap between length and width direction and strip hole, solve in the time of the larger longitudinal loading of pin joint structure transmission, excessive and the adhesive wear problem of pin joint structural volume, be applied in engineering reality, can reduce because of the excessive material causing of pin joint structural volume and artificial waste, meet the requirement of the longitudinal force that between tube and tube, transmission is larger, meet and can load and unload requirement simultaneously.

Embodiment
Referring to Fig. 3, it is a kind of for managing the removable pin Axile connection structure of connection that the utility model provides, comprise pin 3, male connector 2 and with the suitable negative joint 4 of male connector 2; On male connector 2 and negative joint 4, be provided with the pin-and-hole 6 inserting for pin 3, the position that pin 3 contacts with pin-and-hole 6 at least exists a face to contact, be related to that pin 3 and the structural representation of pin-and-hole 6 refer to Fig. 4 and Fig. 5, pin 3 can be cylinder type, identical with existing pin; Can be the structure shown in Fig. 5, be the cotter pilotage of racetrack; No matter which kind of structure pin is, must guarantee that its position contacting with pin-and-hole has individual face to contact.
Pin-and-hole 6 is circular arc type with the cross section of pin 3 surface of contact, and the radius of arc of pin 3 is identical with the radius of arc of pin-and-hole 6.Pin 3 is cylindrical peg 3 or cotter pilotage.
Negative joint 4, male connector 2 are connected with the first connecting tube 1, the second connecting tube 5 butt welding respectively, on joint, have pin-and-hole 6, negative joint 4,2 employing cotter pilotages of male connector connect, the radius of arc of cotter pilotage both sides is identical with the radius of pin-and-hole 6 corresponding positions, aspect width, " cut flat ", make it on length and width direction and between pin-and-hole 6 and all have certain gap.
When longitudinal loading is transmitted in this connection, the suffered longitudinal force of the first connecting tube 1 is delivered on the second connecting tube 5 via male connector 2, cotter pilotage, negative joint 4.
