[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0031] The barber chair of the embodiment of the present invention comprises a lifting mechanism, wherein Figure 1 The lifting mechanism includes a tube body 100 and a sliding block 200. The sliding block 200 is embedded in the tube body 100 and can slide in the tube body 100. The side wall of the sliding block 200 is provided with a sliding groove 210. An abutment block 220 is slidably provided in the sliding groove 210. The abutment block 220 can slide along the radial direction of the tube body 100, and the abutment block 220 and the inner wall of the tube body 100 abut against each other.

[0032] Specifically, during the assembly process, the sliding block 200 is embedded into the tube body 100. Figure 1The sliding block 200 can slide up and down inside the tube body 100. After assembly, by adjusting the position of the abutting block 220 in the slide groove 210, the abutting block 220 and the inner wall of the tube body 100 are abutted against each other and fixed by friction. The pressure between the abutting block 220 and the tube body 100 is adjusted, thereby adjusting the friction between the two, so that the cooperation between the abutting block 220 and the tube body 100 tends to be stable, making the structure of the entire barber chair more stable and smoother to lift and lower.

[0033] Reference Figure 2 A plurality of abutment blocks 220 are arranged on the side wall of the sliding block 200. The abutment blocks 220 abut against the inner wall of the tube body 100, thereby effectively stabilizing the structure of the entire barber chair and improving the stability of use.

[0034] Reference Figure 2 and 3 In the first embodiment of the present invention, the abutment block 220 can and can only slide in the slide groove 210 along the radial direction of the tube body 100, and the abutment block 220 is provided with a groove 221, and a hexagonal nut 222 is embedded in the groove 221. The shape of the groove 221 matches the shape of the hexagonal nut 222, and the hexagonal nut 222 is inserted with an organic screw 223.

[0035] The above-mentioned abutment block 220 can and can only slide in the slide groove 210 along the radial direction of the tube body 100, which means that the abutment block 220 only has the degree of freedom in the radial direction of the tube body 100 on the slide groove 210, and can not rotate in the slide groove 210. Specifically, the abutment block 220 can be set as a cube with edges and corners, and the shape of the inner cavity of the slide groove 210 matches the shape of the abutment block 220; or a guiding mechanism is set between the abutment block 220 and the slide groove 210, such as setting the guide bar 110 and the guide groove on the abutment block 220 and the slide groove 210 respectively.

[0036] In the first embodiment, referring to Figure 3 , so that the machine screw 223 rotates, specifically, the machine screw 223 moves to the right. At this time, the nut moves to the left and abuts against the inner wall of the slide groove 210 to fix the position of the nut. By continuously adjusting the machine screw 223, the pressure between the abutment block 220 and the inner wall of the tube body 100 is adjusted, so that the cooperation between the sliding block 200 and the tube body 100 tends to be stable and the sliding is smooth, and the adjustment after assembly is completed.

[0037] In some embodiments, a push plate 224 is fixed to the end of the machine screw 223. During the feeding process of the machine screw 223, the abutment block 220 is pushed out by the push plate 224 to improve the stability of the structure.

[0038] Reference Figure 4In the second embodiment of the present invention, the abutment block 220 can and can only slide in the slide groove 210 along the radial direction of the tube body 100. The abutment block 220 is inserted with a screw 225. The abutment block 220 and the screw 225 are engaged by threads. In this embodiment, the screw 225 is directly engaged with the abutment block 220. By rotating the screw 225, the abutment block 220 slides in the slide groove 210 to adjust the pressure between the abutment block 220 and the inner wall of the tube body 100. In the second embodiment, the screw 225 directly abuts against the inner wall surface of the slide groove 210, so that the abutment block 220 moves rightward relative to the screw 225.

[0039] In order to adjust the sliding of the abutment block 220 in the first and second embodiments, the side wall of the slide groove 210 disposed on the sliding path of the abutment block 220 is provided with a through hole 230 for the hexagonal wrench to pass through.

[0040] Specifically, in the first embodiment, the hexagonal wrench passes through the through hole 230 and controls the rotation of the screw 223 to adjust the abutment block 220; while in the second embodiment, the hexagonal wrench passes through the through hole 230 and controls the rotation of the screw 225 to adjust the abutment block 220.

[0041] In some embodiments, reference Figure 2 In order to allow the hexagonal wrench to be inserted into the sliding block 200 for adjustment, the sliding block 200 is provided with a clearance position 240 for the hexagonal wrench to be inserted.

[0042] In some embodiments, a positioning groove 250 is disposed on the side wall of the sliding block 200 , and a guide bar 110 is disposed on the inner wall of the tube body 100 , and the guide bar 110 is embedded in the positioning groove 250 .

[0043] In some embodiments, the lifting mechanism further includes a base 300, and the tube body 100 is fixed to the base 300. The base 300 is placed on the ground for use.

[0044] In some embodiments, a driving device 310 is installed on the base 300, and the driving device 310 is provided with a screw 311. The driving device 310 drives the screw 311 to rotate, and the sliding block 200 is fixed with a lifting rod 320. The screw 311 is inserted into the lifting rod 320 and meshes with the lifting rod 320. Specifically, the driving device 310 includes a motor and a reduction gearbox, and the screw 311 is driven to rotate by the reduction gearbox. The screw 311 and the lifting rod 320 are meshed with each other. When the screw 311 rotates, the rotational motion is converted into the up and down motion of the lifting rod 320, thereby driving the lifting rod 320 to move up and down. Specifically, referring to Figure 1The interior of the lifting rod 320 is hollow, and the screw 311 is inserted into the interior of the lifting rod 320. The interior of the lifting rod 320 is provided with a thread, and the thread is engaged with the screw 311, saving space of the entire structure. In other embodiments, the screw 311 can also be directly driven to rotate by a motor.

[0045] In some embodiments, the top of the lifting rod 320 is provided with a mounting protrusion 321. The mounting protrusion 321 is used to install the chair surface, and the chair surface is installed on the entire lifting mechanism, and cooperates with the base 300 to make it a complete barber chair, which is convenient to use.

[0046] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
