Description

Technical Field

[0001] This utility model relates to the technical field of spa equipment for beauty salons, specifically a robotic arm for spa equipment. Background Technology

[0002] Spa, also known as hydrotherapy, is a relaxing and stress-relieving method that combines professional therapists, water, light, aromatherapy, music, and other elements. Spa equipment utilizes water resources in conjunction with bathing, massage, aromatherapy, and the application of skincare products to promote metabolism and satisfy the senses of taste, sight, and touch, thereby achieving a sense of well-being. Existing spa equipment generally includes a main unit, a water tank, and jets. The water tank is located on the main unit, and the jets are connected to the water tank via hoses. Current spa equipment generally uses two types of jets: the first is a fixed structure, which, once fixed, cannot be adjusted in height, thus reducing practicality; the second is a handheld type, where the jet hangs on a hook on the side of the main unit when not in use, requiring manual adjustment of the height during use. Both methods present inconvenience in operation and therefore require improvement. Utility Model Content

[0026] Example 1

[0027] Please see Figures 1-9As shown in this embodiment, a robotic arm for a spa device includes a mounting base 1 with two mounting through holes 2. A cylinder 3 and a triangular ring 4 are located at the front end of the mounting base 1. The piston rod of the cylinder 3 is connected to a cam 5. The cam 5 is hinged to the first side of the triangular ring 4, and the second side of the triangular ring 4 is hinged to one end of a swing arm 6. The end face of the swing arm 6 hinged to the triangular ring 4 abuts against the arc surface of the cam 5. The other end of the swing arm 6 is hinged to a rotating support 7 rotatably connected to the mounting base 1. A rotating arm 8 is hinged to the rear end of the mounting base 1. The lower end of the rotating arm 8 is connected to the rotating support 7, and the upper end of the rotating arm 8 is provided with a pneumatic clamp 9 for clamping the nozzle. For ease of installation, a tripod 10 is provided at the front end of the mounting base 1, and one top end of the tripod 10 is hinged to the third side of the triangular ring 4.

[0028] To ensure rotational stability, a rotating seat 11 is provided below the rotating arm 8. The rotating seat 11 is located on the side of the rotating support 7 and rotates synchronously with the rotating support 7. A positioning beam 12 is connected to the rear end of the mounting base 1. A triangular fixing beam 13 is provided at the other end of the positioning beam 12. The rotating arm 8 is hinged to the triangular fixing beam 13 via a hinge shaft 14. To further ensure rotational stability, an upper support 15 is hinged to the outer side of the upper end of the rotating arm 8. A reinforcing beam 16 is provided on the side of the upper support 15. The other end of the reinforcing beam 16 is hinged to the triangular fixing beam 13.

[0029] like Figure 9 As shown, in order to facilitate disassembly, the pneumatic clamp 9 is provided with an internal thread 17 on its side, and the upper side of the rotating arm 8 is provided with an external thread 18 that mates with the internal thread 17. The pneumatic clamp 9 and the rotating arm 8 are detachably connected, which facilitates disassembly. It should be noted that the pneumatic clamp 9 is a conventional technology in the field, so it will not be described in detail.

[0030] To improve safety, a protective cover 19 is provided on the outside of the cylinder 3. The protective cover 19 includes a protective bottom shell 191 integrally formed with the mounting base 1 and a protective upper shell 192. The protective upper shell 192 is threadedly connected to the protective bottom shell 191 by one or more locking screws 20. The outer shell of the cylinder 3 is hinged to the protective bottom shell 191 by a hinge shaft 21. In order to save costs, the protective cover 19 has a mesh structure. The above structure can facilitate disassembly in the future, and the protective cover 19 outside the cylinder 3 improves safety.

[0031] To ensure rotational stability, a rotating cover 701 is provided at the front end of the rotating support 7. The other end of the rotating cover 701 is hinged to the protective upper shell 192, and the rear end of the rotating cover 701 is in contact with the front end of the triangular ring 4.

[0032] The robotic arm designed in this structure is applied to a spa device. First, two holes are drilled at the corresponding positions on the spa device. Then, screws are passed through these holes and the mounting through-hole 2, and connected to nuts to install the device into the spa device. Next, a pneumatic clamp 9 is used to clamp the nozzle. Then, the cylinder 3 and the pneumatic input port on the pneumatic clamp 9 are connected to an external gas generator. After the gas generator is started, the cylinder 3 works, driving the cam 5 to extend and retract. At the same time, the cam 5 extends and retracts, driving the triangular ring 4 to rotate. Since the side of the cam 5 abuts against the end face of the swing arm 6, and under the synchronous action of the triangular ring 4, the swing arm 6 is affected by the installation structure. After one end of the swing arm 6 rotates, it drives the connection end of the swing arm 6 and the rotating support 7 to rotate, ultimately driving the rotating support 7 to rotate. The rotation of the rotating support 7 drives the lower end of the rotating arm 8 to rotate, ultimately allowing the upper end of the rotating arm 8 to adjust its height. Therefore, this structural design can realize the height adjustment of the spa nozzle, and it is simple to operate, easy to install and disassemble, and can be used in various types of spa devices. Meanwhile, this structure adopts a specific installation structure of cam 5, triangular ring 4, swing arm 6 and rotating support 7, which can ensure the stability of the vertical height adjustment of the upper rotating arm 8.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
