[0032] The following is in conjunction with the appendix Figure 1-6 The present invention will be described in further detail below.

[0033] Example: A headrest lifting structure for a shampoo bed, referring to... Figure 1 It includes a fixing plate 1, which is a metal plate. The fixing plate 1 is arranged vertically and has a U-shaped clearance opening at the top for the user's head and neck to enter.

[0034] A cylindrical through hole is provided at the bottom of the fixing plate 1 for components such as water pipes to pass through, and several smaller mounting holes are provided on the fixing plate 1 for screw fixing.

[0035] A headrest bracket 2 is provided on one side of the fixing plate 1;

[0036] The headrest support 2 is a metal rod, which includes a support rod 22. The support rod 22 is a U-shaped rod, and a vertical rod 21 is fixed to one end of the support rod 22. A second rod 23 is fixed to the other end of the support rod 22. The second rod 23 is set vertically and abuts against the fixing plate 1.

[0037] The included angle between the support rod 22 and the vertical rod 21 in the vertical plane is 90 degrees. In other embodiments, this included angle can be 85 degrees or 95 degrees.

[0038] Reference Figures 2-4 In order to control the vertical height of the headrest bracket 2, there is a locking part 3 and an unlocking part 33 on the fixing plate 1. The locking part 3 controls the vertical rod 21 to be locked and fixed, and the unlocking part 33 allows the vertical rod 21 to move freely vertically. The specific structure is as follows.

[0039] The locking component 3 is a concave structure made of metal, which is welded and fixed to the fixing plate 1. The locking component 3 forms a vertical hole 31 that runs through the top and bottom of the fixing plate 1, and the side of the locking component 3 facing away from the fixing is a downward slope 32. Therefore, the diameter of the vertical hole 31 gradually decreases from top to bottom.

[0040] The vertical rod 21 is inserted through the vertical hole 31.

[0041] The locking component 3 is provided with a locking element 33, which is a ball bearing.

[0042] Under the influence of gravity, one point of the ball abuts against the inclined plane 32, and the other point of the ball abuts against the vertical rod 21, thus achieving the locking and engagement of the two.

[0043] Its working principle is that the inclined plane 32 will give the ball a diagonal upward force, and at the same time the ball will give the vertical rod 21 a lateral force. Under the lateral force, the vertical rod 21 generates an upward static friction force, which will counteract the downward force on the headrest bracket 2, so that the headrest bracket 2 is stably fixed.

[0044] The vertical rod 21 needs to be unlocked to allow it to move freely vertically. This requires the unlocking component 33, the specific structure of which is as follows.

[0045] An unlocking component 33 slides on the fixed plate 1. The unlocking component 33 includes a sliding sleeve 42, which is also a concave structure and is located outside the locking component 3 in a surrounding manner.

[0046] A stop bar 44 is fixed on the locking member 3, and a vertical strip hole 45 is opened on the sliding sleeve 42. The stop bar 44 slides in the strip hole 45. By adopting the sliding relationship between the two, the sliding sleeve 42 can move vertically on the locking member 3.

[0047] The upper part of the sliding sleeve 42 is provided with an upper baffle 43, which is located above the vertical hole 31 and blocks the ball to restrict its slippage.

[0048] The lower part of the sliding sleeve 42 is provided with a lower baffle 46, and the upper baffle 43 is located below the vertical hole 31. The ejector pin 41 is threadedly connected to the lower baffle 46 and points to the locking member 33, which is the ball.

[0049] The unlocking mechanism works as follows: the user lifts the sliding sleeve 42 upwards, which causes the ejector pin 41 to move upwards. The ejector pin 41 then lifts the ball from bottom to top, causing the locking force between the ball and the vertical rod 21 to disappear. At this point, the user can adjust the vertical height of the vertical rod 21, which in turn adjusts the vertical height of the headrest. After adjustment, the user releases the sliding sleeve 42, causing the ball and the vertical rod 21 to re-enter the locking state, thus achieving a lock.

[0050] The advantage of this design is that it allows for multi-level height adjustment with a wide range of height adjustment options.

[0051] Reference Figure 5 When the headrest is installed in the shampoo bed 5, the fixing plate 1 is fixed in the water tank of the shampoo bed 5 with screws.

[0052] Example 2: A headrest lifting structure for a shampoo bed, which differs from Example 1 in that the fixed plate 1 is provided with a sleeve, and the sleeve has a guide hole 6. The second rod 23 slides in the guide hole 6, and the guide hole 6 restricts the second rod 23 from swaying left and right on the fixed plate 1.

[0053] Example 3: A headrest lifting structure for a shampoo bed, which differs from Example 1 or Example 2 in that the vertical rod 21 is an elastic metal rod. When the vertical rod 21 is subjected to pressure from above, it will slightly deform to squeeze the ball bearings, and will return to its original shape after the pressure is removed.

[0054] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
