Technical Field
[0001] The utility model belongs to mechanical connection transmission technology and relates to a quick-connect joint with a universal adjustment function. Background Art
[0002] A quick connection mechanism is required between the connecting rods of a push-pull linkage mechanism to achieve quick disassembly and assembly. At the same time, after the connection, the transmission accuracy cannot be affected by different axial degrees and problems such as jamming cannot occur. This requires the connection mechanism between the connecting rods to have a quick connection function and a universal adjustment function. Since conventional quick connectors do not have a universal adjustment function, connectors with a universal adjustment function do not have a quick connection function. In order to achieve these two functions, it is usually necessary to configure a quick connector to achieve the connection function, and then configure a universal bearing to achieve the universal adjustment function.
[0003] However, the disadvantages of the prior art quick connector are: 1. complex structure; 2. large size. Utility Model Content

[0007] Specifically, a return spring 6 is provided between the support sleeve 4 and the sliding sleeve 5 .
[0008] Specifically, the top rod 3 and the lower connecting rod 8 are in spherical contact, so as to realize the universal adjustment function.
[0009] Specifically, push up the sliding sleeve 5, the steel ball 7 moves outward, and the lower connecting rod 8 is inserted into the supporting sleeve 4; push up the lower connecting rod 8, lift the top rod 3, slide down the sliding sleeve 5, squeeze the steel ball 7, and clamp the lower part of the ball head of the lower connecting rod 8.
[0010] Specifically, the lower connecting rod 8 and the top rod 3 are in close contact under the action of the anti-backlash spring to eliminate the transmission gap; under the action of the steel ball 7, the anti-backlash spring 2 and the top rod 3, the connecting rod and the joint are reliably connected to realize the connection and transmission of the connecting rod mechanism.
[0011] Specifically, the lower connecting rod 8 swings within a limited range between the steel ball 7 and the push rod 3, thereby achieving a universal adjustment effect.
[0012] The utility model has the advantages that the quick connection joint integrates a universal adjustment structure, the push rod and the connecting rod are in spherical contact, and the universal adjustment function is realized while realizing the quick connection function, eliminating the need for a separate universal adjustment mechanism, and has a simple structure and a small size.
