DETAILED DESCRIPTION

[0021] The technical scheme of the utility model will be described clearly and completely in combination with embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0022] Please refer to Figures 1-5 The utility model provides a technical scheme:

[0023] Refer to Figure 1 An arm support mechanism installed on a seat, which is installed on one side of the seat 101 during use. Specifically, it comprises a bottom plate 201 detachably connected with the seat 101, a lifting mechanism vertically installed on the bottom plate 201, a rotating mechanism connected with the lifting mechanism, and a table plate 301 installed on the rotating mechanism. Before haircut, in order to improve the experience of customers, first adjust the arm support mechanism according to the height of the customer, until the table plate 301 is at a suitable spatial position. If the customer needs to use the mobile phone during the haircut process, he can place his arm on the table plate 301 to improve comfort.

[0024] Refer to Figure 2 Or Figure 3 In order to facilitate the installation of the bottom plate 201 on one side of the seat 101, a clamping paw structure can be designed on one side of the bottom plate 201, which can be clamped on the corresponding position on the seat 101 during installation.

[0025] Specifically, refer to Figures 1-3The lifting mechanism is used for controlling the lifting of the table board 301, and comprises a sleeve 401 slidably connected with the bottom plate 201, a rack 402 slidably connected with the sleeve 401, and an adjusting mechanism installed on the sleeve 401 and used for controlling the lifting of the rack 402. The adjusting mechanism comprises a swing sleeve 403 sleeved on the sleeve 401, a rotating disc 404 and a cam 405 oppositely installed on the swing sleeve 403, the swing sleeve 403 is rotationally connected with the sleeve 401, the rotating disc 404 and the cam 405 are both rotationally connected with the swing sleeve 403, and operation handles 701 are installed on the rotating disc 404 and the cam 405. A through hole is formed on the sleeve 401 close to the rotating disc 404, and a helical convex strip 406 is installed on the side wall of the rotating disc 404 close to the through hole. From the perspective of the rotating disc 404, when the helical convex strip 406 on the left side of the rotating disc 404 needs to be engaged with the rack 402, the cam 405 needs to be rotated, the outer periphery of the cam 405 gradually approaches the outer side wall of the sleeve 401 in the rotating process, and after abutting, the cam 405 continues to rotate in the same direction, in this process, the center of rotation of the cam 405 gradually moves away from the outer side wall of the sleeve 401, and at the same time, the helical convex strip 406 gradually approaches the rack 402. When the helical convex strip 406 is completely engaged with the rack 402, the rotating disc 404 is controlled to rotate by the operation handle 701, and the rack 402 is driven by the helical convex strip 406 to move upwards, so that the rack 402 can be lifted. When the table board 301 is stored, the outer periphery of the cam 405 is not in contact with the outer side wall of the sleeve 401, and at the same time, the helical convex strip 406 is not engaged with the rack 402, at this time, the rack 402 falls to the lowest position, which is convenient for storage. Figure 3

[0026] Figure 2 Figure 4 Figure 5 The rotating mechanism in the embodiment comprises a mounting box 501 installed at the top end of the rack 402, first and second face gears 502 and 503 both installed in the mounting box 501, and a swing rod 504 connected with the first face gear 502, the first face gear 502 is slidably connected with the mounting box 501, and the second face gear 503 is fixedly connected with the mounting box 501. The first face gear 502 is moved to the right by the elastic force of the first spring 505 in the balanced state, so that the first face gear 502 is always in engagement with the second face gear 503. When the swing rod 504 needs to be rotated, the first face gear 502 is moved to the left, and in this process, the first spring 505 is compressed. When the first face gear 502 and the second face gear 503 are separated, the swing rod 504 can be rotated. When the swing rod 504 is rotated to a suitable angle, the first face gear 502 is moved to the right until it is re-engaged with the second face gear 503, and then the swing rod 504 can remain at the current angle.

[0027] ​​​​In order to fine-tune the position of the table board 301, the table board 301 and the swing rod 504 are connected by a telescopic mechanism in the embodiment. Specifically, mainly referring to Figure 5 In order to facilitate the installation of the telescopic mechanism, the swing rod 504 is designed as a hollow structure. The telescopic mechanism comprises a support rod 601 connected with the table board 301 and a second spring 602 sleeved on the support rod 601, the top end of the second spring 602 is connected with the table board 301, and the bottom end is connected with the swing rod 504. The swing rod 504 is provided with a transverse transition groove and two longitudinal clamping grooves in communication with each other, and the extension direction of the longitudinal clamping grooves is parallel to the central axis of the swing rod 504. The bottom end of the support rod 601 extends into the swing rod 504, and a clamping rod 603 is installed at the bottom end. Figure 5 From the perspective of the view, the clamping rod 603 always has a tendency to move upward due to the elastic force of the first spring 505 in the balanced state, which makes the clamping rod 603 always be in abutment with the transverse transition groove or the corresponding longitudinal clamping groove. When fine-tuning the position of the table board 301, if the clamping rod 603 is located in the longitudinal clamping groove, press the table board 301 downward until the clamping rod 603 is located in the transverse transition groove, then rotate the table board 301 to drive the clamping rod 603 to rotate, and when the clamping rod 603 can be clamped into another longitudinal clamping groove, release the table board 301, and the clamping rod 603 can be clamped into the corresponding longitudinal clamping groove under the action of the second spring 602. If the clamping rod 603 is located in the transverse transition groove, directly rotate the table board 301 to drive the clamping rod 603 to rotate, and when the clamping rod 603 is located at other positions in the transverse transition groove, stop rotating the table board 301, and the clamping rod 603 is in abutment with the transverse transition groove under the action of the second spring 602.

[0028] The above only describes the preferred embodiments of the present application, and it should be understood that the present application is not limited to the forms disclosed herein, and should not be considered as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concepts described herein by the above teachings or related technologies or knowledge. Any modification and change made by those skilled in the art without departing from the spirit and scope of the present application shall be within the protection scope of the appended claims of the present application.
