Description

Technical Field

[0001] The utility model relates to the technical field of rotary locking, in particular to a quick-disconnect and quick-release rotary locking device. Background Art

[0002] A rotary locking device is a mechanical device used to fix and lock rotating parts to prevent them from loosening or accidentally rotating during use. It is usually used in various machines and equipment that require high-precision rotation operations, such as machine tools, automation equipment, measuring instruments, etc. Rotating parts are usually fixed by using locking pins or locking screws. At the same time, some rotary locking devices are locked and fixed using locking washers or locking nuts.

[0003] The existing rotary locking device is usually a main structure fixed on a fixed component, and a pin and a spring that can be inserted into the hole on the rotating component are connected to the main structure. For example, the Chinese patent with the publication number CN215861429U, entitled: Rotary locking device locked by inertial force, uses the inertia principle of the brake claw. When the rotation speed suddenly increases, that is, the acceleration suddenly increases, the inertia of the brake claw overcomes the tension of the tension spring and produces a backward swinging action, so that the abutment of the brake claw contacts the inner wall of the cavity, thereby realizing the braking function. However, due to the same overall size specifications, the structure can not only only be used in conjunction with the components it is adapted to, but also due to its own structural closedness, it requires the cooperation of multiple people during installation to effectively install and adapt it with external components, thereby affecting its overall stability in use. Therefore, the present application provides a quick-release and quick-disconnect rotary locking device to meet the needs. Utility Model Content

[0004] The purpose of the present application is to provide a quick-release and quick-disassemble rotary locking device, which solves the problems of complicated installation steps and low adaptability in the prior art, and achieves the purpose of improving the overall convenience of use and adaptability.

[0006] Preferably, the interior of the accommodating cavity is fixedly connected to an installation shaft, and a mounting frame is rotatably connected to the installation shaft, and the bottoms of the two mounting frames are respectively fixedly connected to the tops of the first limiting member and the second limiting member.

[0007] Preferably, the side wall of the rotary locking body is connected to the same buffer pad via a plurality of elastic members, and the two buffer pads form an arc structure, the center of the arc structure coincides with the center of the annular structure formed by the first limiting member and the second limiting member.

[0008] Preferably, an adjustment opening is provided at the top of the mounting member, and a control adjustment member is slidably inserted into the adjustment opening, a sensor is fixedly connected to the bottom end of the control adjustment member, and a limit clamping member is provided on the control adjustment member.

[0009] Preferably, the limit engaging parts are a plurality of positioning ring bodies fixedly sleeved on the control and adjustment part, the positioning ring bodies are supported by elastic materials, and the size of the positioning ring bodies is larger than the size of the adjustment port.

[0010] Preferably, two compression springs are fixedly connected to the top of the sensor, and the free ends of the compression springs are fixedly connected to the accommodating cavity.

[0011] In summary, the technical effects and advantages of the utility model are:

[0012] 1. The utility model has a reasonable structure. Through the first limit piece and the second limit piece connected in rotation, the installation piece can be directly placed on the shaft to be fixed during installation, and the first limit piece and the second limit piece are pulled to make the first limit piece and the second limit piece rotate under force, and change their own angular position. The electromagnet can be controlled by an external controller so that the electromagnet can generate a magnetic field under the action of its control force, and then the magnetic suction plate is magnetically fixed. At this time, the magnetic attraction force between the magnetic suction plate and the electromagnet will effectively limit the position of the first limit piece and the second limit piece, so that the first limit piece and the second limit piece clamp the shaft to be fixed from both sides of the shaft, thereby completing the overall installation steps, making it more convenient and stable during installation.

[0013] 2. In the utility model, by providing a sensor, when the mounting piece is placed on the shaft to be fixed, the first limit piece and the second limit piece will rotate downward under the action of their own gravity, so that the free ends of the first limit piece and the second limit piece can be close to each other. At this time, the control adjustment piece can be directly pushed so that the bottom end of the control adjustment piece drives the sensor to move downward, so that the sensor contacts the top of the shaft to be fixed, so that the sensor transmits its contact signal to the external controller, and the controller will autonomously control the electromagnet so that the first limit piece and the second limit piece can perform autonomous installation limit, thereby improving the convenience and intelligence of the overall installation. At the same time, the setting of the limit engaging piece also increases its overall stability. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0026] Combine the following Figure 1-4 The embodiment shown describes the technical solution of the utility model:

[0027] It includes a mounting member 1, which is rotatably connected to a first limit member 5 and a second limit member 6 through a receiving cavity 2, and the mounting member 1, the first limit member 5 and the second limit member 6 are distributed in an annular structure, and the first limit member 5 and the second limit member 6 are both fixedly connected to a rotary locking body 7 inside, the free end of the first limit member 5 is fixedly connected to a magnetic plate 11 through a concave member 10, and the free end of the second limit member 6 is connected to an electromagnet 13 through a placement groove 12, the magnetic plate 11 and the electromagnet 13 are magnetically connected, and the magnetic attraction force of the magnetic plate 11 and the electromagnet 13 directly approaching each other is used to limit the position of the first limit member 5 and the second limit member 6.

[0028] During its use, the mounting member 1 can be directly placed on the shaft to be fixed, and the first limit member 5 and the second limit member 6 can be directly pulled, so that the first limit member 5 and the second limit member 6 are forced to rotate, and then change their own angular position. When it rotates to an appropriate position, the electromagnet 13 can be directly controlled by an external controller, so that the electromagnet 13 can generate a magnetic field under the action of its control force, and then the magnetic attraction plate 11 is magnetically fixed. At this time, the magnetic attraction force between the magnetic attraction plate 11 and the electromagnet 13 will effectively limit the position of the first limit member 5 and the second limit member 6, so that the first limit member 5 and the second limit member 6 clamp the shaft to be fixed from both sides of the shaft, thereby completing the overall installation steps, making it more convenient and stable during installation.

[0029] The interior of the accommodating cavity 2 is fixedly connected, and a shaft member 3 is installed, and a mounting frame 4 is rotatably connected to the mounting shaft member 3. The bottoms of the two mounting frames 4 are fixedly connected to the tops of the first limiting member 5 and the second limiting member 6 respectively.

[0030] When the first limit member 5 and the second limit member 6 are subjected to force, the external force will be transmitted to the mounting frame 4 through the top of itself, so that the mounting frame 4 rotates along the center of the mounting shaft 3 under the action of its force. At this time, the first limit member 5 and the second limit member 6 will change their own positions with the central axis of the mounting shaft 3 as the center under the action of the mounting frame 4, so that the first limit member 5 and the second limit member 6 are separated from each other or approached to each other, thereby simplifying the overall installation steps and making it more convenient during installation.

[0031] The side wall of the rotary locking body 7 is connected to the same buffer pad 9 through a plurality of elastic members 8 , and the two buffer pads 9 form an arc structure, the center of which coincides with the center of the annular structure formed by the first limiting member 5 and the second limiting member 6 .

[0032] During its use, when the first limit member 5 and the second limit member 6 are rotated and clamped from both sides, the buffer pad 9 will first contact the shaft to be fixed. At this time, the buffer pad 9 not only effectively increases the friction between itself and the shaft to be fixed, making its fixed installation more stable, but also, on the size scale of the shaft to be fixed, the buffer pad 9 can also squeeze the elastic member 8 under the action of the space occupied by the shaft to be fixed, so that the elastic member 8 is shortened under the force, and then drives the buffer pad 9 to move, adjust the space inside it, meet the installation and use of shafts to be fixed of different specifications, and improve the flexibility and convenience of its overall installation.

[0033] An adjustment opening is provided at the top of the mounting member 1 , and a control adjustment member 17 is slidably inserted into the adjustment opening. A sensor 16 is fixedly connected to the bottom end of the control adjustment member 17 , and a limit clamping member is provided on the control adjustment member 17 .

[0034] When the mounting member 1 is placed on the shaft to be fixed, the first limit member 5 and the second limit member 6 will rotate downward under the action of their own gravity, so that the free ends of the first limit member 5 and the second limit member 6 can be close to each other. At this time, the control adjustment member 17 can be directly pushed so that the bottom end of the control adjustment member 17 drives the sensor 16 to move downward, so that the sensor 16 contacts the top of the shaft to be fixed, so that the sensor 16 transmits its contact signal to the external controller, and the controller will autonomously control the electromagnet 13, so that the first limit member 5 and the second limit member 6 are autonomously installed and limited, thereby improving the convenience and intelligence of the overall installation. At the same time, the setting of the limit clamping member also increases its overall stability.

[0035] The limiting engaging member is a plurality of positioning ring bodies 18 fixedly sleeved on the control adjusting member 17 . The positioning ring bodies 18 are supported by elastic material, and the size of the positioning ring bodies 18 is larger than the size of the adjusting port.

[0036] During its use, the positioning ring body 18 will be deformed under the action of external force and the restriction of the adjustment port, thereby reducing the overall diameter, so that the positioning ring body 18 will slide along with the control adjustment member 17. When it slides to a suitable position, the force on the positioning ring body 18 disappears, and it can be reset autonomously at this time, so that it can be engaged with the adjustment port under the action of its size, thereby ensuring the stability of the position of the control adjustment member 17 and the sensor 16 during use.

[0037] Two compression springs 15 are fixedly connected to the top of the sensor 16 , and the free ends of the compression springs 15 are fixedly connected to the accommodating cavity 2 .

[0038] When the sensor 16 is moved by force, its moving force will effectively act on the compression spring 15, causing the compression spring 15 to deform under the action of its force, thereby effectively buffering the moving force of the sensor 16, making it more stable during adjustment and use.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
