Abstract

The utility model relates to a hinge joint, which belongs to mechanism design in the technical field of machine design, in particular to a connecting joint, which comprises a joint (1) and a lug sheet (2). The joint is in a shape of a tub, a cylinder central spindle (3) is arranged at the hub bottom, and a fixed hole is arranged at the edge. The lug sheet is also in a shape of a tub, a central spindle hole (4) matched with the cylinder central spindle (3) is arranged at the hub bottom, a fixed hole is also arranged at the edge of the lug sheet, the position and the size of the fixed hole of the of the lug sheet is in one-to-one correspondence with those of the fixed hole of the joint (1). The hinge joint is simple in structure, reliable in fixing and small in occupation space, greatly reduces space of the hinge in a movement mechanism, and enables arrangement of the movement mechanism to be tighter and the volume to be more small and exquisite.

Description

A kind of knuckle joint

Technical field

The invention belongs to the mechanism design field of mechanical design field, be specifically related to a kind of jointing.

Background technique

Hinge is used very extensive in the mechanical mechanism design, is the important element that constitutes motion, especially in compound movement mechanism, has played the effect that can not be substituted.Modal hinge is made up of two Earring connectors and a mandrel usually, generally selects for use bolt as mandrel, and attaching nut can play the effect of hinge joint, can play fixation again.But along with the complicated and exquisitenessization of motion, requiring the hinge joint joint to take up room can not be excessive, otherwise whole motion volume is increased, and in mechanism's product, can't arrange, especially for example is used for high, refined, peak products such as Aeronautics and Astronautics.

In addition, in standard No. is the aviation boat industry standard of HB8229-2002, disclose a kind of fork ear joint, in standard No. is the aviation boat industry standard of HB8228-2002, disclose a kind of Earring connector.Fork ear joint is a knuckle joint, and two flat auricles are arranged, and has the mandrel hole in auricle central vertical auricle direction.Earring connector has only a flat auricle, and auricle central vertical auricle direction has the mandrel hole.Fork ear joint and Earring connector are used, and the auricle of Earring connector is stretched in two auricles of fork ear joint, make the alignment of mandrel hole, and passing the mandrel hole with bolt, to form hinge movement secondary, and fasten with nut.This kind hinge is in the process with mechanism's motion, and space is decided by connecting bolt length, and it is excessive to cause motion to take up room, or in product, is difficult for arranging, especially under the environment that mechanism's high density such as aircraft, airship are concentrated.

Summary of the invention

Deficiencies such as excessive, the difficult layout that takes up room to existing knuckle joint; The utility model proposes a kind ofly can to solve above-mentioned knuckle joint and receive the mandrel effect length; It is excessive to take the motion space, causes the motion volume to increase, in product, be difficult for the new hinges joint of problems such as layout.

The concrete scheme that the utility model is taked is: a kind of knuckle joint, comprise a joint (1) and an auricle (2), and joint (1) is the bathtub shape, and cylindric mandrel (3) is arranged at the bottom of the basin, the edge has fixed hole; Auricle (2) also is the bathtub shape, and its bottom has the mandrel hole (4) of matching with cylindric mandrel (3), and fixed hole is also opened at auricle (2) edge, and its position and size are corresponding one by one with the position and the size of the fixed hole of joint (1).

During use, the mandrel (3) of joint (1) is passed other mandrel holes of stranded, with auricle (2) and joint (1) assembling relatively, make mandrel (3) insert mandrel hole (4) again, again joint (1) is connected with fastening piece with auricle (2).Thereby realize the knuckle joint twisting.

The good effect that the present invention produces: the utility model principle is simple, and is fixed, take up room for a short time, greatly reduced the space of hinge in motion, makes that the layout of motion is tightr, and volume is more small and exquisite.

Embodiment

For better implement the utility model, the utility model is elaborated below in conjunction with Figure of description 1～Fig. 4 and specific embodiment.

Embodiment 1

Present embodiment is the knuckle joint that is used for general motion mechanism, and is as shown in Figure 1, comprises a joint 1 and an auricle 2; Joint 1 is the bathtub shape; Low promptly, the structure that both sides are high, its bottom central are provided with cylindric mandrel 3; Edge has 2 fixed holes, and fixed hole position and cylindric mandrel 3 are point-blank; Auricle 2 also is the bathtub shape, and its bottom central has the circular core axis hole 4 that matches with cylindric mandrel 3, and 2 fixed holes are also opened at auricle 2 edges, and the fixed hole position of auricle 2 is corresponding one by one with size with the position of size and joint 1 fixed hole.

During use, the mandrel 3 of joint 1 is passed the mandrel hole of Earring connector 5, again joint 1 and auricle 2 assembles relatively, mandrel 3 is inserted be positioned at the mandrel hole 4 on the auricle, again joint 1 is connected with auricle 2 usefulness bolts, thus the realization twisting.

Embodiment 2

Present embodiment is the knuckle joint that is used for the connecting rod rocking arm, and is as shown in Figure 4, comprises a joint 1 and an auricle 2; Joint 1 is the bathtub shape, and is promptly middle low, the structure that both sides are high; Its bottom is provided with cylindric mandrel 3; Edge has 2 fixed holes, fixed hole position and cylindric mandrel 3 not point-blank, its position, three places becomes an obtuse triangle; Auricle 2 also is the bathtub shape, and its bottom has the circular core axis hole 4 that matches with cylindric mandrel 3, and 2 fixed holes are also opened at auricle 2 edges, and the fixed hole position of auricle 2 is corresponding one by one with size with the position of size and joint 1 fixed hole.

The mandrel 3 of joint 1 is passed the mandrel hole of Earring connector 5, again joint 1 and auricle 2 assembles relatively, mandrel 3 is inserted be positioned at the mandrel hole 4 on the auricle, joint 1 is connected with auricle 2 usefulness bolts fixes again.Earring connector 5 is connected with pull bar 7, and joint 1 is connected with a rocking arm 6, thereby constitutes the connecting rod rocker arm body.

The utility model makes it simple in structure through bathtub shape structure is set, and is fixed, take up room for a short time, greatly reduced the space of hinge in motion, makes that the layout of motion is tightr, and volume is more small and exquisite.

Claims (1)

1. knuckle joint, it is characterized in that: comprise a joint (1) and an auricle (2), joint (1) is the bathtub shape, and cylindric mandrel (3) is arranged at the bottom of the basin, and the edge has fixed hole; Auricle (2) also is the bathtub shape, and its bottom has the mandrel hole (4) of matching with cylindric mandrel (3), and fixed hole is also opened at auricle (2) edge, and its position and size are corresponding one by one with the position and the size of the fixed hole of joint (1).
