DETAILED DESCRIPTION

[0024] The present invention is further described in detail below in conjunction with specific implementation methods.

[0025] The multifunctional health equipment includes a machine body and a manipulator mounted on the machine body. An operation panel and a main controller with a preset control program are installed inside the machine body. The main controller controls the connection between the operation panel and the manipulator. A quick-release assembly is installed at the end of the manipulator. Figure 1 The assembly body 1 is provided with a mounting seat 11, an upper fixing seat 12 and an annular lower fixing seat 13 from top to bottom, wherein the mounting seat 11 is connected to the end of the manipulator (not shown in the figure) by bolt connection or welding, and the mounting seat 11, the upper fixing seat 12 and the lower fixing seat 13 are fixed together by bolts. A rotating cylinder 2 is provided between the upper fixing seat 12 and the lower fixing seat 13, and the rotating cylinder 2 is sleeved on the outer side of the upper fixing seat 12 so that the upper fixing seat 12 is hidden inside. Figure 6A torsion spring 4 is provided on the top surface of the upper fixed seat 12 , the beginning end of the torsion spring 4 is connected to the upper fixed seat 12 and the end end is connected to the rotating cylinder 2 , and under the restoring force of the torsion spring 4 , the rotating cylinder 2 can rotate positively around the vertical axis relative to the upper fixed seat 12 .

[0026] See Figure 2 The lower end of the rotating cylinder 2 is hollow to form a mounting cavity 21, and a stopper 5 is provided between the rotating cylinder 2 and the upper fixing seat 12. Figure 7 , the upper part of the limiter 5 is inserted into the upper fixed seat 12 in a manner that it cannot rotate relative to the upper fixed seat 12, while the lower part is inserted into the installation cavity 21 of the rotating cylinder 2 in a manner that it can rotate relative to the rotating cylinder 2. The middle part of the limiter 5 has two symmetrically arranged limiters 51 that extend radially outward; the bottom surface of the upper fixed seat 12 has two first accommodating cavities 121 that are respectively aligned with the two limiters 51, and the top surface of the rotating cylinder 2 has two second accommodating cavities 22 that are respectively aligned with the two limiters 51. A spring 6 is provided between the limiter 5 and the upper fixed seat 12. Under the action of the spring 6 force of the spring 6, the limiter 5 drives its two limiters 51 to move downward and embed into the two second accommodating cavities 22 of the rotating cylinder 2. The rotating cylinder 2 is thus limited by the two limiters of the limiter 5 and cannot rotate around its own vertical axis. At this time, the rotating cylinder 2 is in the initial state, and the torsion spring 4 is in a compressed state / tensioned state.

[0027] See Figure 2 , the installation cavity 21 of the rotating cylinder 2 faces downward, and is connected to the lower part of the lower fixing seat 13 through the inner ring of the annular lower fixing seat 13. A mounting frame 3 is provided below the lower fixing seat 13. The operator can select one of the functional heads with different functions (not shown in the figure), and removably install the selected functional head below the mounting frame 3 by bolt connection, and then install the top of the mounting frame 3 from bottom to top into the installation cavity 21 through the inner ring of the annular lower fixing seat 13. To this end, the cavity wall of the installation cavity 21 has three locking protrusions 211 arranged circumferentially at intervals extending radially inward, and the top of the mounting frame 3 has three wedge-shaped locking blocks 31 (see FIG. 1 ) arranged circumferentially at intervals extending radially outward. Figure 1 ).See Figure 7In the process of the mounting frame 3 moving upward from the bottom to be installed in the mounting cavity 21, the top pushes upward the lower part of the stopper 5 extending into the mounting cavity 21 of the rotating cylinder 2, driving the stopper 5 and the stopper portion 51 embedded in the second accommodating cavity 22 to overcome the spring 6 force of the spring 6 and move upward. After the mounting frame 3 moves upward to its position, the stopper portion 51 of the stopper 5 completely leaves the second accommodating cavity 22 of the rotating cylinder 2 and is embedded upward into the first accommodating cavity 121 of the upper fixing seat 12. At this time, the stopper portion 51 of the stopper 5 releases the limit on the rotating cylinder 2; at the same time, the three wedge-shaped locking blocks 31 of the mounting frame 3 have all passed over the three locking protrusions 211 of the rotating cylinder 2 upward. After the limit is released, the rotating cylinder 2, under the action of the restoring force of the torsion spring 4, drives the three locking protrusions on its cavity wall to lock. The three locking protrusions 211 rotate forward together until they rotate forward to under the three wedge-shaped locking blocks 31 of the mounting frame 3 respectively, and the three locking protrusions 211 are respectively pressed upward against the three wedge-shaped locking blocks 31, and the three locking protrusions 211 and the three wedge-shaped locking blocks 31 are thus buckled together to achieve locking, and the top of the mounting frame 3 is thereby installed in the mounting cavity 21 of the rotating cylinder 2, and the functional head installed on the mounting frame 3 is then installed in the component body 1. When it is necessary to remove the mounting frame 3 from the mounting cavity 21, the operator needs to hold the lower fixing seat 13 with one hand and move the shifting block 23 on the outer side of the rotating cylinder 2 with the other hand to make the rotating cylinder 2 rotate in the opposite direction, thereby driving the three locking protrusions 211 to rotate in the opposite direction until they leave the three wedge-shaped locking blocks 31 of the mounting frame 3, and the three locking protrusions 211 and the three wedge-shaped locking blocks 31 are no longer buckled together, and the operator can remove the top of the mounting frame 3 from the mounting cavity 21 of the rotating cylinder 2, and the functional head installed on the mounting frame 3 is removed from the component body 1; when the rotating cylinder 2 rotates in the opposite direction until its two second accommodating chambers 22 are realigned with the two first accommodating chambers 121 of the upper fixing seat 12, the limiting member 5 drives its two limiting parts 51 to move downward under the spring 6 force of the spring 6, so that the two limiting parts 51 leave the two first accommodating chambers 121 and are re-embedded in the two aligned second accommodating chambers 22, and the rotating cylinder 2 is re-positioned, so that the rotating cylinder 2 is restored to its initial state.

[0028] See Figure 4 A damping buffer gear 7 is meshed at the inner wall of the top of the rotating cylinder 2, and the damping buffer gear 7 is installed on the upper fixed seat 12. When the rotating cylinder 2 rotates, the damping buffer gear 7 will be driven to rotate, that is, the rotating cylinder 2 needs to overcome the resistance of the damping buffer gear 7 during the rotation process, thereby ensuring that the rotating cylinder 2 will not rotate forward at a faster speed under the restoring force of the torsion spring 4, and the rotating cylinder 2 is not easily subjected to a large hard impact after rotating forward to the position.

[0029] See Figure 3, a locking force detection sensor switch 81 is installed on the upper fixing seat 12, and the locking force detection sensor switch 81 can be a travel switch of model TC-5610H8-T. The main controller in the body of the multifunctional health equipment controls the connection of the locking force detection sensor switch 81. The rotating cylinder 2 partially extends inward with a contact portion 24. The rotating cylinder 2 rotates forward under the reset force of the torsion spring 4. During the movement, its contact portion 24 touches the detection portion of the locking force detection sensor switch 81. The locking force detection sensor switch 81 thus detects the rotational locking force of the rotating cylinder 2 passing through, and sends the measured locking force value to the main controller. If the locking force data is higher than the preset value, the main controller believes that the rotational locking force of the rotating cylinder 2 is normal and sufficient to lock the mounting frame 3; otherwise, it is abnormal, and the main controller controls the operation panel to display an error message to remind the operator to repair the quick-release assembly in time.

[0030] See Figure 5 , an in-place detection switch 82 is installed on the upper fixing seat 12, which is located directly above the limit member 5. The in-place detection switch 82 can be a push button switch of model XKB7070-W, and the main controller in the body of the multifunctional health equipment controls the connection of the in-place detection switch 82. In the process of the mounting frame 3 being loaded into the mounting cavity 21 of the rotating cylinder 2 from bottom to top, the push limit member 5 moves upward, and after the mounting frame 3 moves into place, the top of the limit member 5 just moves upward to touch and press the in-place detection switch 82, thereby activating the in-place detection switch 82 to send an activation signal to the main controller. In the default state, the main controller controls the operation panel to display a prompt message that the mounting frame 3 is not loaded; if the main controller receives an activation signal from the in-place detection switch 82, the control operation panel displays a prompt message that the mounting frame 3 has been loaded, so that the operator can intuitively understand the loading status of the mounting frame 3 from the operation panel.

[0031] Preferably, see Figure 1 , a mounting bracket 91 extending downward is installed around the mounting seat 11, and an identifier 92 is installed at the bottom of the mounting bracket 91. The main controller in the multifunctional health equipment body controls the connection of the identifier 92. The mounting frame 3 has seven vertical through holes 32 arranged at intervals, and the functional head (not shown in the figure) is equipped with a plurality of ejectors (not shown in the figure). The number of ejectors of the functional heads with different functions is different, and after the different functional heads are installed on the mounting frame 3, the ejectors are accommodated in different vertical through holes 32 and extend above the vertical through holes 32. In this way, when the mounting frame 3 is installed in the mounting cavity 21 of the rotating cylinder 2, the ejectors extending above the vertical through holes 32 contact the identifier 92, and the identifier 92 thereby identifies the number and position of the ejectors, and sends the identification information to the main controller. The main controller determines the type of the functional head according to the identification information, and controls the movement of the manipulator in the subsequent operation according to the preset program, thereby driving the functional head to move and perform corresponding beauty, maintenance, physical therapy, massage, monitoring and other operations.

[0032] In this embodiment, the rotating cylinder 2 is used as a locking device, the three locking protrusions 211 of the rotating cylinder 2 are used as locking parts, and the three wedge-shaped locking blocks 31 of the mounting frame 3 are used as locking parts, and the torsion spring 4 is used as an elastic member. The locking part of the locking device can lock the locking part of the mounting frame 3 that has been loaded into the mounting cavity 21 under the action of the reset force of the elastic member, that is, the mounting frame can be locked into the component body. Therefore, the locking device does not need to be driven by a pneumatic or electric drive component, and there is no need to equip the drive component with an air pipe or electrical connection line. Therefore, the multifunctional large health equipment with the quick-release component occupies less space and has lower cost. In other embodiments, the locking device may not be the rotating cylinder 2, but a fixed cylinder fixedly installed between the upper fixed seat 12 and the lower fixed seat 13. Accordingly, the fixed cylinder is provided with a radially inward elastic wedge block used as a locking portion, and the mounting frame 3 is provided with a groove used as a locking portion. When the mounting frame 3 is installed into the fixed cylinder, the elastic wedge block is first pushed radially outward to make it avoid. After the mounting frame 3 passes over the elastic wedge block, the groove of the mounting frame 3 is aligned with the elastic wedge block. The elastic wedge block is reset radially inward and snapped into the groove under the action of its own reset force, thereby locking the mounting frame 3.

[0033] The above is only an implementation method of the invention, and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the invention, which still fall within the scope of patent protection.
