This invention enables quick connection and disconnection of two shafts via the support frame, and ensures smooth operation after connection.

Description

Technical Field

[0001] This utility model relates to the field of mechanical connection technology, specifically a quick connection and separation bracket. Background Technology

[0002] In mechanical assembly and connection processes, cumbersome disassembly causes inconvenience and affects work efficiency in actual operation. Traditional brackets connecting the two ends of the rods consist of clamping blocks with multiple fasteners. Tightening and loosening bolts and nuts one by one is required for connection and release, a repetitive process. Sometimes, the space for assembly and disassembly is too small, preventing tools from entering. Furthermore, the clamping blocks often become stuck, causing misalignment of the two ends of the rods and resulting in jamming during operation. Therefore, the above connection mechanism needs to be optimized. Utility Model Content

[0003] This invention provides a quick-connect and disconnect bracket, aiming to improve mechanical assembly efficiency and the smooth operation of the connecting mechanism.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A quick-connect and disconnect bracket includes a main support frame installed between receiving plate I and receiving plate II; shaft I is movably installed above the main support frame, and shaft II is movably installed below the main support frame, with the adjacent parts of the two connected by a piston stop rod of a stop rod mechanism to engage a mushroom head; the piston stop rod is elastically mounted on a connecting block, which is installed at the lower end of shaft I; the upper mushroom head and the inner hole at the lower end of shaft I are movably connected with a clearance fit, and the lower threaded part of the mushroom head is threadedly connected to shaft II; between the upper mushroom head and the lower threaded part of the mushroom head is a smooth rod, on which a double cone is slidably mounted; the upper conical surface of the double cone and the lower arcuate inclined surface of the piston stop rod are movably engaged.

[0005] The distance from the upper end face of shaft II to the top of the mushroom head is less than the depth of the inner hole at the lower end of shaft I.

[0006] The bottom of the connecting block is pressed against the lower part of the inner cavity of the main support frame by an adjusting bolt, and an adjusting nut is fitted on the adjusting bolt.

[0007] The stop mechanism includes a piston stop, a spring, and a screw plug; the connecting block has a transverse through threaded hole in which the screw plug, spring, and piston stop are installed sequentially from the rear end to the front end.

[0008] This utility model can quickly connect and disconnect two shafts through a support frame. Since the arc-shaped top surface of the mushroom head can swing at a small angle in the inner hole of shaft I, the "binding" phenomenon will not occur after connection, thus achieving the purpose of smooth operation.

Detailed Implementation

[0010] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0011] Reference Figure 1 In this invention, shafts I and II are in a normal connection state, with the upper mushroom head of the mushroom head 15 blocked by the piston stop rod 4, forming a normal connection. The specific structure is as follows: A quick-connect and disconnect bracket includes a main support frame 3 installed between receiving plate I2 and receiving plate II9; shaft I1 is movably installed above the main support frame 3, and shaft II10 is movably installed below the main support frame 3, with the adjacent parts of the two connected by a piston stop rod 4 of a stop rod mechanism to hold a mushroom head 15; the piston stop rod 4 is elastically installed on a connecting block 14, and the connecting block 14 is installed on the lower end of shaft I1 by a tightening screw 16; the upper mushroom head of mushroom head 15 is movably connected to the inner hole of the lower end of shaft I1 with clearance fit, and the lower threaded part of mushroom head 15 is threadedly connected to shaft II10; between the upper mushroom head and the lower threaded part of mushroom head 15 is a smooth rod, on which a double cone 13 is slidably installed; the upper conical surface of the double cone 13 is movably engaged with the lower arcuate inclined surface of the piston stop rod 4, while the outer periphery of the double cone 13 is slidably engaged with the inner hole of the lower end of shaft I1 with clearance fit. Mushroom head 15 extends upward, pushing open piston stop rod 4 and compressing spring 5. When the upper mushroom head of mushroom head 15 enters the inner hole of shaft I1, piston stop rod is stuck at the bottom of upper mushroom head under the action of spring. At this time, when shaft II is pulled down, shaft II is connected to shaft I. When shaft II continues to push upward, piston stop rod 4 will be pushed open by movable double cone. When pulled down again, it will quickly disengage, thus achieving rapid disengagement.

[0012] The receiving plate I2 is connected to the main support frame 3 via stud I17 and nut I18, and the receiving plate II9 is ​​connected to the main support frame 3 via stud II12 and nut II11.

[0013] When connecting the lower threaded part of the mushroom head 15 to the threaded hole of shaft II 10, the distance from the upper end face of shaft II 10 or the bottom surface of the double cone 13 to the top of the mushroom head 15 should be less than the inner hole depth of the lower end of shaft I 1 to ensure that the two shafts can be quickly disengaged.

[0014] The bottom of the connecting block 14 is pressed against the lower part of the inner cavity of the main support frame 3 by an adjusting bolt 8, and an adjusting nut 7 is fitted on the adjusting bolt 8. The distance between the connecting block 14 and the lower part of the inner cavity of the main support frame 3 can be adjusted by rotating the adjusting nut 7.

[0015] The stop mechanism includes a piston stop 4, a spring 5, and a screw plug 6. The connecting block 14 has a transverse through-threaded hole, in which the screw plug 6, spring 5, and piston stop 4 are sequentially installed from rear to front. The screw plug 6 adjusts the compression of the spring 5 by screwing it into the thread of the connecting block 14. Adjusting the compression controls the extension and retraction force of the piston stop 4 for better operation. Specifically: if the spring force is too high, the screw plug can be rotated outwards to reduce the spring compression; if the spring force is too low, the screw plug can be rotated inwards to increase the spring compression. Alternatively, replacing the spring with one with a larger pitch is also a solution.

[0016] Figure 2 In the upward-moving state of the movable double cone of this utility model, due to the upward movement of shaft II, the movable double cone pushes open the piston stop rod. After being pushed open, due to the action of the spring at the rear end of the piston stop rod, the spring is compressed, and the spring preload increases. Since the movable double cone is a conical surface, the piston stop rod pushes down along the conical surface, pushing the movable double cone to the upper end of the piston stop rod, forming... Figure 2 The state.

[0017] Figure 3 In the downward movement of this utility model, shaft II is in the undisengaged state. At this time, shaft II moves downward, and the movable double cone slides on the smooth rod of mushroom head 15, and is pushed by the piston rod all the way to the bottom of the upper mushroom head of mushroom head 15; until it fits against the bottom of the upper mushroom head, forming... Figure 3 The state.

[0018] Figure 4 This is the instantaneous disengagement state of shaft II during downward movement, at which point shaft II is in... Figure 3 As the state continues to descend, because the movable double cone is inclined, it pushes the piston rod aside. At this time, the upper conical surface of the movable double cone is hidden at the bottom of the recess of the upper mushroom head. As shaft II continues to descend, it pushes aside the arc head that passes through the upper mushroom head, forming... Figure 4The instantaneous departure from the state.

[0019] Figure 5 In the downward disengagement state of shaft II of this utility model, the movable double cone, under its own weight, falls onto the end of shaft II, forming... Figure 5 Completely detached from the state.
