Description

Technical Field

[0001] The invention relates to the technical field of coupling mechanisms, in particular to a quick-release coupling mechanism. Background Art

[0002] In mechanical connections, couplings are used as a mechanical component to connect the driving shaft and the driven shaft in different mechanisms so that the two shafts can rotate together and transmit torque. Couplings usually consist of two parts, the driving end and the driven end, which are connected to the driving shaft and the driven shaft respectively. For products running at low speeds, rigid couplings are often used for connection.

[0003] The connection between the active end and the driven end of the rigid coupling is generally tightened by passing through multiple sets of bolts. If the active end and the driven end need to be separated, each bolt needs to be removed before the coupling can be separated. The disassembly and assembly process is relatively cumbersome. The patent authorization announcement number CN2011039432U and the authorization announcement number CN2014063592U both show rigid connections that are easily damaged due to frequent disassembly and assembly, and have a poor service life. Traditional rigid couplings are not suitable for some shaft connection conditions with low speed and small transmission torque but with the need for fast and frequent disassembly and assembly. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide a quick-release coupling mechanism, which can replace the traditional rigid coupling. The coupling has a compact structure, is easy to manufacture, and is convenient to disassemble and assemble. It not only ensures the connection function of the coupling, but also greatly improves the efficiency of disassembly and assembly of the coupling, and can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a quick-release coupling mechanism, comprising an active end fixedly connected to an external active shaft, the active end being a disc-shaped structure, a bottom support plate being fixed on one side of the active end, both ends of the bottom support plate being provided with grooves, a rotating ear seat being rotatably arranged in the groove at the left end of the bottom support plate through a cylindrical pin, the rotating ear seat being connected with an integrally connected clamping hoop cover, a driven end being fixed between the clamping hoop cover and the bottom support plate, the central axis of the driven end and the central axis of the active end being located on the same straight line, the inside of the groove at the left end of the bottom support plate being rotatably connected with a live bolt through another cylindrical pin, one end of the clamping hoop cover being provided with a U-shaped hole corresponding to the live bolt, the upper end of the live bolt being provided with a hexagonal cylindrical nut for pressing the end of the clamping hoop cover downward, the hexagonal cylindrical nut being used to fix the clamping hoop cover and one end of the bottom support plate so that the clamping hoop cover and the bottom support plate are clamped and fixed to the driven end.

[0006] Furthermore, mounting holes are evenly arranged at the uniform edge of the active end, and the mounting holes are distributed in a circular structure. One end of the cylindrical pin is fixedly installed in cooperation with the mounting hole, and the mounting hole is for the bolts to pass through when the active end is installed.

[0007] Furthermore, two bottom support circular holes corresponding to the cylindrical pins are provided on the bottom support plate, and the bottom support circular holes and the cylindrical pins are interference fit. The middle of the bottom support plate is a U-shaped structure, and the U-shaped structure corresponds to the outer side of the driven end. The bottom support side plates on both sides of the U-shaped structure of the bottom support plate correspond to the outer side of the driven end.

[0008] Furthermore, the middle of the clamp cover is an arc structure, and the arc is arranged corresponding to the outer side of the upper end of the driven end.

[0009] Furthermore, the driven end includes a hollow circular shaft, one end of which is provided with two chamfered surfaces corresponding to the bottom support side plates, and the other end of which is evenly provided with mounting ear plates connected to the external driven shaft.

[0010] Furthermore, a limiting protrusion is fixed on the lower end of the hollow circular shaft, and a limiting hole corresponding to the limiting protrusion is provided on the bottom plate of the bottom support.

[0011] Furthermore, a spring washer and a flat washer are provided between the lower surface of the hexagonal cylindrical nut and the upper surface of the clamp cover. The spring washer and the flat washer are stacked together from top to bottom, and the spring washer and the flat washer are sleeved onto the outer side of the movable bolt.

[0012] Compared with the prior art, the invention has the following advantages: 1. The present invention assembles the U-shaped structure of the bottom support plate at the driven end according to the angle of the mating surface, so that the bottom support side plate on the bottom support plate fits with the chamfered surface of the driven end, and the limiting protrusion of the driven end is embedded in the limiting hole on the bottom support plate, so as to prevent the driven end and the driving end from rotating.

[0013] 2. The present invention wraps the driven end by pressing down the clamp cover, and the outer side of the hollow circular shaft on the driven end is tightly attached by the bottom support plate and the clamp cover. The spring washer and the flat washer arranged under the hexagonal cylindrical nut are pressed onto the clamp cover, and the hexagonal cylindrical nut is tightened. The clamp cover presses the driven end, thereby completing the connection between the driving end and the driven end of the coupling.

[0014] 3. The separation of the present invention is carried out in the reverse order. After loosening the hexagonal cylindrical nut, the clamp cover is opened to complete the separation of the active end and the driven end. The quick-release coupling mechanism can replace the traditional rigid coupling in some shaft connection conditions with low rotation speed and small transmission torque but with the demand for fast and frequent disassembly and assembly. It has a compact structure, is easy to manufacture and convenient to disassemble and assemble, which not only ensures the connection function of the coupling, but also greatly improves the efficiency of disassembly and assembly of the coupling.
