Description

Technical Field

[0001] This utility model relates to the field of barber chair technology, specifically a barber chair with an adjustable base. Background Technology

[0002] A barber chair is a specialized chair used in barbershops, hair salons, and medical hairdressing facilities for customers to get their hair cut. It combines the needs of the hairdresser with the comfort of the customer. In particular, to ensure that the hairdressing requirements of customers of different heights are met and that the customer is comfortable during the haircut, barber chairs are generally equipped with an adjustable base.

[0003] A Chinese utility model patent with authorization announcement number CN214341196U discloses a height-adjustable seat, including a base. Multiple support sleeves are vertically fixed on the base, and lifting rods are telescopically arranged within the support sleeves. A support plate is fixedly connected to the upper end of all the lifting rods. A backrest is fixedly connected to the support plate, and a support rod is fixedly connected to the lower surface of the support plate. Multiple first pads and multiple second pads are movably arranged on the base, with the first and second pads staggered, supporting the support rods. This utility model changes the seat height by altering the number of first and second pads below the support rods. Compared to the existing technology that uses cylinders for adjustment, this method is safer and more reliable, effectively preventing user safety hazards caused by cylinder aging and damage leading to explosions.

[0004] Currently, traditional barber chairs have the following problems:

[0005] To reduce costs and ensure safety, existing barber chairs typically use mechanical height adjustment instead of pneumatic cylinders for seat height adjustment, thus retaining the lifting function while reducing maintenance costs and the probability of damage. However, traditional mechanical height adjustment requires pressing or stepping on the chair to reposition the chair after each adjustment, which is inconvenient for the barber. Furthermore, without repositioning the chair, the barber needs to apply significant force to support both the chair and the customer, posing a safety risk. Utility Model Content

[0006] The purpose of this invention is to provide a barber chair with an adjustable base to solve the problems mentioned in the background art.

[0007] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0027] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0028] Please see Figures 1-5 A barber chair with an adjustable base includes a seat 10; a self-locking lifting adjustment structure 30 installed at the center of the bottom of the seat 10 by screws; a hydraulic buffer cylinder 40 installed at the inner bottom of the self-locking lifting adjustment structure 30 and extending to the outer side; and a base plate 50 installed at the bottom of the output end of the hydraulic buffer cylinder 40. The self-locking lifting adjustment structure 30 includes a gear lifting assembly 301 installed at the center of the bottom of the seat 10; and a self-locking turntable assembly 302 installed on the side of the gear lifting assembly 301 and driven by the gear lifting assembly 301. The hydraulic buffer cylinder 40 is installed at the inner bottom of the gear lifting assembly 301.

[0029] In practical use, the above-described solution allows for manual assembly of the chair seat 10, self-locking height adjustment structure 30, hydraulic buffer cylinder 40, and base plate 50 during the barber chair assembly process. When the height of the chair seat 10 needs adjustment, the barber uses their knees to press down or lift the gear lifting assembly 301, achieving height adjustment of the chair seat 10 through toothed engagement. Simultaneously, after each adjustment, the self-locking turntable assembly 302 operates. The internal linkage structure of the self-locking turntable assembly 302 limits and locks the gear lifting assembly 301 after each adjustment, ensuring safety and stability during chair seat 10 position adjustments.

[0030] For details, please refer to the following: Figure 2 Handles 20 are installed on both sides of the top of the seat 10, and the outer side of the top of the seat 10 is covered with a soft pad made of rubber material that is installed by screws.

[0031] For details, please refer to the following: Figure 3 and Figure 4 The gear lifting assembly 301 includes: an upper mounting base 3011 mounted on the center of the bottom of the seat 10 by screws; a toothed metal slide rod 3012 mounted on the center of the bottom of the upper mounting base 3011; a metal sleeve 3013 movably disposed on the outside of the toothed metal slide rod 3012; a lower sleeve 3014 mounted on the bottom of the metal sleeve 3013; a movable gear 3015 meshing with the side of the toothed metal slide rod 3012 and movably connected inside the metal sleeve 3013; and a movable push rod 3016 connected to the shaft end of the movable gear 3015.

[0032] In this design, a protrusion 30121 protruding outward is installed on the side of the toothed metal slide bar 3012 away from the tooth surface. The protrusion 30121 extends into the interior of the metal sleeve 3013 and is slidably connected to the metal sleeve 3013.

[0033] It should be noted that the shaft end of the movable gear 3015 is also connected to a self-locking turntable assembly 302 that is away from the movable push rod 3016. The self-locking turntable assembly 302 is movably disposed on the outside of the metal sleeve 3013. The lower sleeve 3014 has a hydraulic buffer cylinder 40 that extends to the outside installed inside.

[0034] This utility model discloses a barber chair with an adjustable base. When the chair seat 10 needs to be adjusted in height, the barber's knees will press or lift the movable push rod 3016, causing the movable gear 3015 connected to the movable push rod 3016 to rotate. When the movable gear 3015 rotates, the toothed metal slide rod 3012, which is meshed with its side, will move up and down inside the metal sleeve 3013, causing the top of the metal sleeve 3013 to move up and down through the chair seat 10 mounted on the upper mounting base 3011.

[0035] For details, please refer to the following: Figure 4 and Figure 5 The self-locking turntable assembly 302 includes: a movable turntable 3021 movably connected to the outer side of the shaft end of the movable gear 3015 and mounted on the outer side of the metal sleeve 3013; a cam arm 3022 connected to the shaft end of the movable gear 3015 and movably disposed on the side of the movable turntable 3021; ​​and a limiting protrusion 3023 rotatably connected to the cam arm 3022 and abutting against the outer wall of the movable turntable 3021.

[0036] This utility model discloses a barber chair with an adjustable base. When the movable gear 3015 rotates, the cam arm 3022 mounted on its outer side rotates, driving the limiting protrusion 3023, which is eccentrically connected to the cam arm 3022, to move within the recessed portion of the outer wall of the movable turntable 3021. When the limiting protrusion 3023 moves to the inner side of the recessed portion of the outer wall of the movable turntable 3021, it limits the rotation of the movable gear 3015 through a meshing connection. When the limiting protrusion 3023 moves to the outer side of the recessed portion of the outer wall of the movable turntable 3021, it can rotate freely.

[0037] It should be noted that a return spring is provided on the inner side of the connection between the cam arm 3022 and the limiting protrusion 3023.

[0038] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
