Description

Technical Field

[0001] The utility model belongs to the field of components of medical magnetic stimulation treatment equipment, in particular to a head support bracket of a magnetic stimulation instrument. Background Art

[0002] The Chinese patent "A support structure of a magnetic field stimulator" (publication number:) published on June 15, 2021, the patented technical solution includes: a substrate, a headrest, a magnetic field stimulator and an angle-adjustable connecting rod, the headrest is slidably connected to the substrate, the connecting rod is connected to the headrest, and the magnetic field stimulator is installed on the connecting rod. It connects the magnetic field stimulator to the headrest through a connecting rod. When the patient's head twists and moves, the headrest slides along the substrate under the action of the patient's head, so that the magnetic field stimulator on the connecting rod moves with the headrest. Because the headrest and the substrate slide together through the sliders and slide rails thereon, the patient can move the headrest very quickly, which makes the patient prone to symptoms of dizziness in this case. Utility Model Content

[0003] The technical problem solved by the utility model is to provide a head support bracket for a magnetic stimulator, which solves the problem that the headrest slides too fast.

[0004] In order to solve the above technical problems, the utility model adopts a technical solution including: a base plate, movable plates are respectively provided on the upper and lower parts of the base plate, an adjustment arm connected to the magnetic stimulation coil is provided on the movable plate located above the base plate, sliding columns are relatively provided on the two movable plates, one side of the two movable plates is connected to the head support, a rotating shaft is movably connected between the two movable plates, a gear is provided on the rotating shaft, a positioning hole is provided on the base plate, a rack matching the gear is provided on one side of the positioning hole, the rack is connected to a spring, the rack is located in a limiting groove, and the rotating shaft passes through the positioning hole.

[0005] Furthermore, a locking device is provided on the outer side of the rack, and the locking device includes: a push plate, and the push plate is connected to the push plate driving device.

[0006] Furthermore, the end of the sliding column is a spherical surface.

[0007] Furthermore, the upper and lower surfaces of the substrate are respectively provided with sliding plates or sliding bars.

[0008] Furthermore, a bracket is provided above the push plate driving device, a sliding bar is provided on the bracket, and the bracket is located below the upper movable plate.

[0009] Furthermore, the push plate driving device is an electric push-pull rod.

[0010] Furthermore, the sliding bar is located at the contact point between the sliding housing and the substrate.

[0011] The utility model reduces the rotation speed of the headrest by movably connecting the gear and the rack matched therewith on the base plate, and the compression meshing of the rack and the gear, thereby reducing the dizziness of the patient when turning the head. At the same time, the double-layer movable plate is used to make the sliding on the base plate more stable, avoiding the radial swinging of the adjustment arm caused by the increase in the gap between the slider and the slide rail after long-term use. Secondly, by setting a locking device, for some patients whose heads are tilted to one side and difficult to turn, or patients whose heads are constantly swinging, such as children, the headrest needs to be positioned at a fixed angle to prevent the random and disorderly movement of the headrest from causing damage to the magnetic stimulation equipment or other injuries to the patient. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a cross-sectional schematic diagram of an implementation mode of the utility model. Figure 2 It is a top view schematic diagram of an implementation mode of the utility model. DETAILED DESCRIPTION

[0013] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0014] like Figure 1 and Figure 2 The utility model shown in the figure includes: a base plate 1, on which a positioning hole 2 and a seat connecting rod 20 are provided, and the seat connecting rod 20 is used to be inserted into the docking hole of the seat. A movable plate 3 is provided on the upper and lower parts of the base plate 1. An adjustment arm 4 connected to a magnetic stimulation coil 7 is provided on the movable plate 3 located above the base plate 1, and the adjustment arm 4 is composed of two arm rods, and the two arm rods are movably connected. The angles of the two arm rods are adjusted by screwing a handle 5. One of the arm rods is connected to the base plate 1 through a spherical joint to adjust the connection angle of the arm rod connected thereto through the spherical joint. A clamping groove is provided on the other arm rod, and a tightening screw 6 is provided at the clamping groove. The tightening screw 6 is tightened to make it cooperate with the clamping groove to clamp the magnetic stimulation coil 7. Sliding columns 8 are relatively provided on the two movable plates 3 on the upper and lower parts of the base plate 1 to provide support force for the movable plates 3 arranged on the upper and lower parts, and the ends of the sliding columns 8 are spherical to reduce the contact area between the sliding columns 8 and the base plate 1, thereby facilitating the movement of the movable plate 3 on the base plate 1. At the same time, metal sliding bars 21 are respectively provided on the upper and lower surfaces of the substrate 1 . The sliding bars 21 are located below or above the sliding column 8 and in contact with the substrate 1 to reduce the wear of the sliding column 8 .

[0015] One side of the two movable plates 3 is connected to the headrest 10 through a U-shaped joint 9, so that the headrest 10 and the movable plates 3 move together. The two movable plates 3 are movably connected to the two ends of the rotating shaft 12 through bearings 11, and a gear 13 is provided on the rotating shaft 12, and the rotating shaft 12 passes through the positioning hole 2 on the base plate 1. An arc-shaped rack 15 matching the gear 13 is provided on one side of the positioning hole 2, and the rack 15 is connected to a spring 16, and the rack 15 is located in a limiting groove 17, so that the spring 16 pushes the rack 15 along the limiting groove 17 to press against the gear 15, so that the gear 13 meshing with the rack 15 forms a certain resistance when rotating, thereby reducing the rotation speed of the headrest 10 connected to the movable plate 3.

[0016] A locking device is provided on the outer side of the rack 15, and the locking device includes: a push plate 18, and the push plate 18 is connected to the push plate driving device 19. An arc-shaped bracket 14 is provided above the push plate driving device 19, and a metal sliding bar is also provided on the bracket 14. The bracket 14 is located below the upper movable plate 3. The bracket 14 includes: a column and a crossbeam 141, and the crossbeam 141 is arc-shaped, and the columns are connected to both ends of the crossbeam 141. The bracket 14 is set to prevent the movable plate 3 above it from being squeezed on the push plate driving device 19, thereby affecting the rotation of the movable plate 3. When the locking device needs to lock the angle of the head support 10, the screw rod of the push plate driving device 19 extends through the push plate 18 and is pressed against the gear 13 with the rack 15, so that the gear 13 cannot be displaced and the position of the head support 10 is fixed to meet the needs of different patients.

[0017] As an improvement of the present invention, sliding plates having an area equivalent to that of the substrate may also be arranged on the upper surface and the lower surface of the substrate.
