Embodiment 1

[0029] A quick release interconnection device, such as Figure 1~3 As shown, it includes a retractable cylinder 3, a marble 4, a floating cylinder 5, a tension spring 6, an outer support cylinder 7, a locking seat 8, a pull rod 14 and a locking wrench 15. The shrink tube 3 and the locking seat 8 are installed on both ends of the outer support tube 7 respectively. Shrink tube 3 axial center is provided with the cavity 31 of up big and down small (with the direction close to locking seat 8 as the bottom), and this cavity 31 and shrink tube 3 are coaxial. This cavity 31 can be designed as inverted cone, funnel-shaped, also can be designed as figure 1 As shown in the stepped shape including two steps, the diameter on the side close to the locking seat 8 is smaller, and the transition between the two steps is smooth, for example, through the chamfered slope at both ends. The floating cylinder 5 is coaxially (ie, coaxial with the shrinking cylinder 3 ) arranged in the shrinking cy...

Embodiment 2

[0036] This embodiment discloses another quick-release interconnection device. The only difference between the quick-release interconnection device and the first embodiment is that it also includes a fixing seat 2, and the fixing seat 2 is provided with a through hole 19 that matches the shrinkable tube 3. , the shrink tube 3 is installed at the through hole 19 and is axially connected with the through hole 19 .

Embodiment 3

[0038] This embodiment discloses another quick-release interconnection device. The only difference between this quick-release interconnection device and Embodiment 1 is that the locking wrench 15 is replaced by a rotating nut, the pull rod 14 is designed as a screw structure, and the connection between the locking seat 8 and the rotating nut There is no connection between them, and the rotating nut is arranged on the pull rod 14. Turn the rotating nut to keep the pull rod 14 away from the shrink tube 3, so that fast interconnection and locking can be realized. Rotate the rotating nut in the opposite direction to make the pull rod 14 close to the shrink tube 3, and unlocking is realized.

[0039] The locking wrench 15 can also be replaced by other pull rod pulling mechanisms, as long as it can drive the pull rod 14 to move axially. As for the locking or unlocking of the state after connecting any device 1, it can be realized with the help of other auxiliary devices.

Abstract

The invention discloses a quickly-disassembled interconnection device. A shrinkage cylinder and a locking seat are mounted at two ends of an outer supporting cylinder respectively; a cavity is formed in the axis of the shrinkage cylinder; the inner diameter of the cavity is designed to be large in top and small in bottom; a floating cylinder is arranged in the shrinkage cylinder and extends out of the shrinkage cylinder; the shrinkage cylinder, the cavity and the floating cylinder are coaxial; a plurality of marble holes are evenly formed in the same horizontal plane of a part, located in the shrinkage cylinder, of the floating cylinder in a radial direction, and a marble is arranged in each marble hole; one end of a pulling rod is connected with the floating cylinder, and the other end of the pulling rod is connected with a pulling rod pulling mechanism; the pulling rod pulling mechanism moves so as to drive the pulling rod to move in an axial direction; the free end of the pulling rod penetrates through a bottom plate of the floating cylinder and extends into the floating cylinder; a first movable mechanism is arranged at the free end of the pulling rod and can move in an axial direction of the pulling rod; and a compression spring is arranged between the first movable mechanism and the bottom plate of the floating cylinder. According to the design, the compression amount of the compression spring can be conveniently adjusted, so that the locking strength is adjusted so as to be adapted to different loads.

Description

technical field [0001] The invention relates to a mechanical engineering component, in particular to a quick-release interconnection device. Background technique [0002] In the field of mechanical engineering, because it is difficult to directly manufacture and process mechanical equipment into a large-scale state, mechanical parts often need to be processed first and then connected. In most cases, there is a need for a portable connection between devices, so as to achieve quick installation or removal. [0003] In order to meet the above requirements, some quick-connect assemblies have been designed, such as a quick-change collet assembly proposed by CN210889641U. However, this type of quick connection assembly cannot cope with bolt bodies of different lengths, and the locking force on the bolt body can only rely on the gravity of the device, making the connection not firm enough. Contents of the invention [0004] The purpose of the present invention is to provide a q...
