[0033] The utility model will be further explained in detail in combination with the drawings.

[0034] Embodiment 1, a head bracket for washing head, refer to Figures 1-3 , including fixed plate 1, fixed plate 1 is the metal plate of Y-shaped structure as a whole, the lower end structure of fixed plate 1 is relatively wide, the lower end of fixed plate 1 is provided with a through hole, and the through hole is used for the extension of the water pipe.

[0035] Fixed plate 1 is fixed with vertical pipe 2, vertical pipe 2 is welded on fixed plate 1, and vertical pipe 2 and fixed plate 1 enclose a pipe body structure.

[0036] Vertical pipe 2 is a square tube as a whole, and two vertical pipes 2 are parallelly arranged.

[0037] Vertical pipe 2 is inserted with vertical rod 31. The upper end of the two vertical rods 31 is fixed with support rod 32;

[0038] Support rod 32 is a U-shaped rod. Support rod 32 and vertical rod 31 are integrally formed metal rod bodies, and vertical rod 31 is bent and formed at the end of support rod 32.

[0039] Vertical pipe 2 guides vertical rod 31, and vertical rod 31 moves up and down stably under the action of vertical pipe 2.

[0040] Support rod 32 is located at the upper end of vertical rod 31, so that the height adjustment of vertical rod 31 can drive the height of support rod 32.

[0041] The function of support rod 32 is to support the head of the user who lies flat.

[0042] In order to lock the vertical position of vertical rod 31, the following locking structure of cam 41 is arranged, and the specific structure is as follows.

[0043] Cam 41 is an eccentric wheel, and fixed plate 1 is fixedly provided with a rotating shaft, cam 41 is rotatably connected to fixed plate 1 through the rotating shaft, and the both ends of the rotating shaft are provided with stop blocks, so that cam 41 cannot be freely separated along the axis direction of the rotating shaft.

[0044] The side of the cam 41 is towards the vertical rod 31, the cam 41 rotates along the rotation shaft, the curved surface of the cam 41 is towards the vertical rod 31 and is attached to the vertical rod 31 until the point with larger radius extrudes the vertical rod 31, so that the vertical rod 31 is extruded between the cam 41 and the inner wall of the vertical pipe 2.

[0045] In order to facilitate the side of the cam 41 to contact the vertical rod 31, a cutout 21 is arranged on one side of the vertical pipe 2, the cutout 21 is a rectangular opening. The curved surface of the edge of the cam 41 enters the inside of the vertical pipe 2 through the cutout 21.

[0046] In order to facilitate the user to rotate the cam 41, the edge of the cam 41 is fixed with an outwardly extending swing rod 42; the swing rod 42 and the cam 41 are integrally formed metal parts.

[0047] The swing rod 42 is convenient for the user to hold and exert force with the hand.

[0048] As shown in Figure 2 , and further optimization is that the cam 41 is in extrusion locking with the vertical rod 31 at this time, and the radius of the curved surface of the cam 41 towards the vertical rod 31 gradually decreases from above the extrusion point to below, and the purpose of this design is that when the user presses on the support rod 32, the downward pressure makes the locking relationship between the vertical rod 31 and the cam 41 more firm.

[0049] If the vertical rod 31 has a downward movement trend, it will drive the cam 41 to have a downward rotation movement trend, and the upper radius of the cam 41 is larger, and the upper curved surface is more tightly extruded when it rotates downward, so that the vertical rod 31 is more tightly extruded, and the locking effect of the vertical rod 31 is more excellent.

[0050] When the vertical rod 31 is unlocked, only the swing rod 42 is rotated Figure 4 , so that the two cams 41 and the respective vertical rods 31 are separated, at this time the user can freely adjust the height of the vertical rod 31 and the support rod 32 to select the appropriate height of the support rod 32.

[0051] The installation structure of the bracket in the hair washing bed Figure 5 , the bracket is fixed on the sink by screws, the user lies on the bed plate, then the neck of the user is inserted into the sink through the fixed plate 1, and the support rod 32 supports the head of the user.

[0052] Embodiment 2, a head support for hair washing, which is different from embodiment 1 in that, referring to Figures 6-9 , the two surfaces of the vertical rod 31 clamped are flat vertical surfaces 5; one vertical surface 5 is towards the cam 41, and the other vertical surface 5 is towards the inner wall of the vertical pipe 2.

[0053] When the cam 41 presses the vertical rod 31, one vertical surface 5 of the vertical rod 31 and the inner wall of the vertical pipe 2 are in close contact with each other in the clamping state; the other vertical surface 5 of the vertical rod 31 and the edge of the cam 41 are in close contact with each other in the clamping state.

[0054] Such a design is to facilitate the pressing contact surface of the vertical rod 31 and the vertical pipe 2 and the cam 41, so that the pressing locking state is more stable.

[0055] Embodiment 3, a head bracket for washing hair, which is different from the head bracket of Embodiment 1 or Embodiment 2, wherein referring to Figure 10 , the fixed plate 1 is provided with a sliding groove 61, and the sliding groove 61 is a vertical groove;

[0056] The sliding groove 61 is slidably provided with a stop rod 62. The cross section of the sliding groove 61 is T-shaped, so that one end of the stop rod 62 cooperates with the T-shaped structure of the sliding groove 61, so that the stop rod 62 is difficult to separate from the sliding groove 61;

[0057] The lower end of the sliding groove 61 is located on one side of the locking state of the cam 41, and at this time the stop rod 62 is located on one side of the swing rod 42, and the stop rod 62 limits the swing to move to the unlocking state; that is, when the cam 41 presses the vertical rod 31, the stop rod 62 slides to one side of the swing rod 42 to limit the swing rod 42 to unlock rotation in a blocking manner. Such a design is to avoid accidental unlocking of the cam 41, which causes the sudden falling of the supporting rod 32 to cause harm to the user.

[0058] The unlocking operation is that the user can first move the stop rod 62 upward, move the stop rod 62 out of the swing rotation path, and then rotate the swing rod 42, so that the swing rotation state is obtained.

[0059] The above only describes the preferred embodiments of the present application, and the protection scope of the present application is not limited to the above-mentioned embodiments. Any technical solution falling within the scope of the present application is within the protection scope of the present application. It should be noted that for ordinary technical personnel in the technical field, some improvements and decorations without departing from the principle of the present application are also considered as the protection scope of the present application.
