[0030] Reference Figure 1-5 A hand rest adjustment structure for a beauty bed includes a hand rest assembly and a swing adjustment mechanism for driving the hand rest assembly. The hand rest assembly includes a hand rest pad 1, a movable seat 2, and a swing arm 3. The swing arm 3 is mounted on the action output end of the swing adjustment mechanism. The left and right sides of the swing arm 3 are each provided with a movable guide groove 31, and the movable guide groove 31 extends from front to back.

[0031] Furthermore, the hand rest pad 1 is mounted on the top of the movable base 2. The left and right ends of the bottom of the movable base 2 are both protruded with guide connection parts 21. The two guide connection parts 21 correspond to the left and right sides of the swing arm 3 respectively. The inner side of the guide connection part 21 is provided with a guide connection block 4 that is guided and fitted in the movable guide groove 31.

[0032] Furthermore, a plurality of locking grooves 22 arranged along the movement adjustment direction are provided on the bottom of the movable seat 2, and a locking member 5 capable of being inserted into one of the locking grooves 22 to lock the position of the movable seat 2 is provided on the swing arm 3.

[0033] In this embodiment, the cooperation between the movable base 2 and the swing arm 3 allows the hand rest pad 1 on the movable base 2 to be adjusted in position as the movable base 2 moves forward and backward. After the position of the movable base 2 is determined, the locking member 5 can be used to lock it, so that the hand rest pad 1 can better support the user's arm, so that the beauty bed can better meet the needs of users of different body shapes, improve the overall user experience of the beauty bed, and promote the healthy development of the beauty industry.

[0034] In this embodiment, the guide connecting block 4 is fixed to the guide connecting part 21 by means of guide bolts, and the cross-sectional shapes of the movable guide groove 31 and the guide connecting block 4 are both T-shaped, so that the movable guide groove 31 and the guide connecting block 4 can be slidably buckled together, thereby preventing the guide connecting part 21 from opening to the left or right and causing the guide connecting block 4 to detach from the movable guide groove 31, effectively ensuring the stability of the fit between them.

[0035] In this embodiment, the palm rest pad 1 includes a palm rest base 11 and a soft cushion 12 mounted on the top and around the palm rest base 11. The top of the movable seat 2 is fixedly connected to the palm rest base 11 by a first bolt. The soft cushion 12 can be formed by wrapping a sponge with cloth on the palm rest base 11, which can improve the comfort of the user when placing his hand on the soft cushion 12.

[0036] As a preferred embodiment, covers 6 are installed at both the front and rear ends of the swing arm 3, and the covers 6 are fixed to the swing arm 3 by a second bolt. The two covers 6 are respectively arranged at the two ends of the movable guide groove 31, thereby limiting the guide connecting block 4 from sliding along the movable guide groove 31 and detaching from the swing arm 3, thereby ensuring the stability of the guide.

[0037] As a preferred embodiment, a locking seat 7 is provided in the swing arm 3, and a first guide hole 71 and a spring mounting groove 72 are provided on the locking seat 7, which are axially connected in sequence from top to bottom. The top of the swing arm 3 is provided with a top opening 33 corresponding to the first guide hole 71, and the bottom is provided with a bottom opening 34 corresponding to the spring mounting groove 72; the locking member 5 includes a locking head 51, a spring limiting portion 52 and a central axis portion 53 connected in sequence along the axial direction. The locking head 51 is guided and fitted in the first guide hole 71 and can be inserted into one of the locking grooves 22 through the top opening 33 to achieve the position of the mobile seat 2 Locking; the spring limiting portion 52 and the central axis portion 53 are located in the spring mounting groove 72, and a locking spring 8 and a limiting seat 9 for supporting the locking spring 8 are provided in the spring mounting groove 72 for keeping the locking head 51 inserted into one of the locking grooves 22. The locking spring 8 is sleeved on the central axis portion 53, and the bottom of the locking spring 8 rests on the limiting seat 9, and the top rests on the spring limiting portion 52; the limiting seat 9 is penetrated from top to bottom with a second guide hole 91 for the central axis portion 53 to guide and pass through, and the bottom of the central axis portion 53 passes through the bottom opening 34 and is installed with an operating head 10.

[0038] When the user pulls the operating head 10 downward, the locking head 51 can be moved downward out of the locking groove 22 to release the movable seat 2, allowing the user to slide and adjust the position of the movable seat 2. During this process, the locking spring 8 is compressed and stores energy; when the user releases the operating head 10, the locking spring 8 releases energy and opens to drive the locking head 51 to reset upward. At this time, if a certain locking groove 22 just corresponds to the top opening 33, the locking head 51 can be extended into the locking groove 22 under the action of the locking spring 8 to lock the position of the movable seat 2.

[0039] In this embodiment, the interior of the swing arm 3 is a swing cavity 30, and the locking seat 7 is installed in the swing cavity 30. There are two guide limit protrusions 301 protruding from the swing cavity 30, and the two guide limit protrusions 301 correspond to two movable guide grooves 31 respectively. The locking seat 7 is provided with positioning matching grooves 73 corresponding to the two guide limit protrusions 301 respectively, so that the locking seat 7 is limited to rotate in the swing cavity 30 through this structural design.

[0040] In this embodiment, the lower end of the limit seat 9 extends from the bottom opening 34, and a limit connection portion 92 is provided on its outer periphery. The limit connection portion 92 is fixedly connected to the bottom of the swing arm 3 using a third bolt, thereby completing the installation of the limit seat 9. Furthermore, the top-view cross-sectional shapes of the limit seat 9 and the spring installation slot 72 are both polygonal, preferably quadrilateral, and the top-view cross-sectional dimensions of the limit seat 9 and the spring installation slot 72 are similar. When the limit connection portion 92 is fixed to the swing arm 3, the limit seat 9 cooperates with the spring installation slot 72 to prevent the locking seat 7 from moving forward or backward, thereby completing the positioning and installation of the locking seat 7.

[0041] In this embodiment, the swing adjustment mechanism includes a supporting link 101, an installation link 102, two support links 103, and an electric push rod 104. The supporting link 101 is installed on the bottom of the swing arm 3. The front and rear ends of the supporting link 101 are respectively hinged to the upper ends of the two support links 103, and the front and rear ends of the installation link 102 are respectively hinged to the lower ends of the two support links 103. The supporting link 101, the installation link 102, and the two support links 103 form a four-bar mechanism, which is a parallel four-bar mechanism. The fixed end of the electric push rod 104 is hinged to the installation link 102, and the movable end is hinged to one of the support links 103. The electric push rod 104 is controlled by a controller. The user sends a control command to the controller through the control switch. The controller controls the electric push rod 104 to drive the four-bar mechanism to move, thereby adjusting the position of the hand rest assembly. Of course, the swing adjustment mechanism is not limited to the present embodiment. In other embodiments, the swing adjustment mechanism may also be a mechanism for driving the adjustment of the palm rest assembly using the technical solution of patent number 202320848450.0.

[0042] The above description is only a preferred embodiment of the present invention. Any technical solution that achieves the purpose of the present invention by substantially the same means shall fall within the scope of protection of the present invention.
