The height adjusting mechanism 4 mainly includes the sliding rail seat 41, the cylinder body 42, and the starting member 44. The overall structure is easy to install, has less changes to the beauty table body, has good adaptability, and can reduce production cost.
[0037] The specific structure of the cylinder body 42 is as follows: comprising a cylinder 421, an oil cylinder 422, a piston 423, a piston rod 427, and a driving rod 426. The oil cylinder 422 is installed in the cylinder 421, and divides the cylinder 421 into a gas cavity 4211 and an oil cavity 4212, and the gas cavity 4211 and the oil cavity 4212 are not communicated with each other (the function of the gas cavity 4211 is to fill gas to generate gas pressure, so as to prevent the oil in the oil cavity 4212 from leaking into the gas cavity 4211 at the front end of the oil cylinder 422). In order to ensure the sealing between the gas cavity 4211 and the oil cavity 4212, the utility model is provided with a sealing element 43 at the front end of the oil cylinder 422 to prevent oil and gas leakage (the sealing element 43 can be used to prevent the oil in the oil cavity 4212 from leaking into the gas cavity 4211). The piston 423 is installed in the oil cylinder 422 and is provided with a valve cover 424 at the front end, and a thimble 425 is further arranged in the piston 423, and the thimble 425 abuts against the valve cover 424. The valve cover 424 is normally closed to prevent the mutual flow of oil between the two sides of the piston 423 in the oil cylinder 422. More specifically, the chamber at the rear side of the piston 423 is the oil cavity 4212, the space at the front side of the piston 423 is an oil storage chamber 4221, and the valve cover 424 controls the flow passage of oil between the oil cavity 4212 and the oil storage chamber 4221. In the embodiment, an oil blocking plug 4231 is arranged in the piston 423, and an oil passing passage 4232 is further arranged at the rear side of the valve cover 424. When the valve cover 424 is opened, the oil in the side with larger oil pressure in the oil storage chamber 4221 and the oil cavity 4212 flows into the other cavity through the oil passing passage 4232. The thimble 425 is used to control the opening and closing of the valve cover 424, and a piston rod 427 is connected to the rear end of the oil blocking plug 4231 in the piston 423. The rear end of the piston rod 427 penetrates out of the cylinder 421, and a driving rod 426 penetrates into the piston rod 427 and is connected to the rear end of the thimble 425 at one end. The other end of the driving rod 426 penetrates out of the piston rod 427 and passes through the support frame 13 to drive the starting element 44. The oil blocking plug 4231 is arranged on the thimble 425. Since the rear end of the thimble 425 is connected to the piston rod 427 and the driving rod 426, the oil blocking plug 4231 is used to prevent oil from leaking onto the driving rod 426 behind the oil blocking plug 4231 during oil flow. In addition, a sealing plug 428 is fixedly arranged on the piston rod 427. The sealing plug 428 is located at the rear side of the oil cylinder 422, the cylinder 421 can slide relative to the sealing plug 428, the range of the oil cavity 4212 is limited between the sealing plug 428 and the valve cover 424, and the oil cannot leak onto the piston rod 427 at the rear side portion through the sealing plug 428.
[0038] The starting member 44 comprises a U-shaped blocking box 441 fixed outside the support frame 13, the driving rod 426 passes through the end of the support frame 13 and is placed in the blocking box 441, a handle 443 penetrates into the blocking box 441 and is located behind the driving rod 426, the middle part of the blocking box 441 transversely passes through a pivot 445, the pivot 445 transversely passes through and is fixed at the front section of the handle 443, the handle 443 is pivoted in the blocking box 441 through the pivot 445, and the front end of the handle 443 located in the blocking box 441 is provided with an abutting piece 442 which can abut against the driving rod 426 after the handle 443 is rotated. In the embodiment, the first through hole 444 is arranged on each side surface of the blocking box 441, the second through hole (not shown in the figure) is arranged on the two sides of the handle 443 corresponding to the first through hole 444, the pivot 445 passes through the first through hole 444 and the second through hole so that the abutting piece 442 is pivoted in the blocking box 441, and the angle of the abutting piece 442 can be adjusted by rotating the handle 443 to abut against the driving rod 426.
[0039] The working principle of the height adjusting mechanism 4 is as follows:
[0040] The valve cover 424 is in a normally closed state due to the oil pressure, and the valve cover 424 can be kept open only when the driving rod 426 keeps abutting, and the ejector pin 425 can keep the valve cover 424 open. When the valve cover 424 is open, the oil storage chamber 4221 and the oil cavity 4212 are in communication with each other, so that the oil can flow between the oil storage chamber 4221 and the oil cavity 4212 through the oil passage 4232 on the piston 423 and the gap between the piston 423 and the oil cylinder 422.
[0041] When it is necessary to adjust the height of the table board 11, the user lifts the handle 443 to change the angle of the abutting piece 442, the end of the driving rod 426 penetrating out of the support frame 13 is abutted, the driving rod 426 is displaced forward after being abutted by the abutting piece 442, and the ejector pin 425 moves forward under the action of the driving rod 426 to open the valve cover 424. Since the oil storage chamber 4221 and the oil cavity 4212 can communicate with each other only when the valve cover 424 is open, and the oil can flow in the two chambers, the cylinder body 42 can move only when the valve cover 424 is open, that is, the second table leg member 122 can slide in the slide rail seat 41; at this time, the user can select to raise or lower the height of the table board, and in this process, the angle between the two table leg members changes, the second table leg member 122 slides in the slide rail seat 41 to drive the entire cylinder body 42 to move forward and backward. Since the valve cover 424 is in an open state, the pressure in each chamber in the cylinder body 42 can be kept in a balanced state through the flow of the oil along with the movement of the cylinder body 42, and at this time, the height of the table board can be raised or lowered smoothly.
[0042] When the table board 11 is adjusted to a suitable height, the user presses down the handle 443, the driving rod 426 is not pressed, the valve cover 424 is closed due to the oil pressure, the oil no longer flows, at this time the pressure of each chamber in the cylinder body 42 is in a balanced state, the cylinder body 42 cannot move any more, therefore the second table leg part 122 cannot slide in the slide rail seat 41, the crossing angle between the two table leg parts cannot be changed, and the height of the table board 11 is locked.
[0043] Therefore, the user can adjust the height of the table board 11 through the height adjusting mechanism 4, and adjust the height of the pet on the table to the most suitable working height of the user, so that the user does not need to bend down to work and the working burden is reduced. In addition, the height of the table board 11 can be adjusted and locked only by lifting or pressing down the handle 443, so that the use is simple and convenient, and the user can adjust immediately.
[0044] The above is only one embodiment of the utility model, and does not limit the utility model, and any modification, equivalent replacement and improvement within the spirit and principle of the utility model should be included in the protection scope of the utility model.
