Detailed implementation manners

[0031] Next, the technical solutions of the present utility model will be described clearly and completely in conjunction with the attached drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0032] As Figure 1 shown, the present utility model provides a head bracket, and the head bracket at least includes: a base 1, an adjustment mechanism 2, a clamping mechanism, and a mounting mechanism 3.

[0033] The adjustment mechanism 2 at least includes a first electric push rod 201, a headrest plate 4, a first sliding mechanism, and a second sliding mechanism; the first electric push rod 201 is fixedly installed above the base 1, and the headrest plate 4 is connected to the first electric push rod 201; the first sliding mechanism at least includes a first slide rail 214, and the second sliding mechanism at least includes a second slide rail 206, a rack 205 arranged on the side of the second slide rail 206, a sliding member 207 sliding on the second slide rail 206, and a gear 210 connected to the sliding member 207 and meshing with the rack 205; the first sliding mechanism and the second sliding mechanism are arranged on both sides of the headrest plate 4 through a support rod 203.

[0034] As Figure 2 shown, in some embodiments, a connecting block 202 is further provided between the first electric push rod 201 and the headrest plate 4, the connecting block 202 connects the first electric push rod 201 and the headrest plate 4, and the headrest plate 4 is installed on the connecting block 202.

[0035] As Figure 3As shown in the figure, a bearing 211 and a second moving rod 212 are successively connected above the gear 210. A motor shaft 209 and a motor 208 are successively connected below the gear 210, and the motor 208 is connected to the sliding member 207. Among them, the setting of the motor 208 can make the movement of the entire head bracket more precise, avoiding many uncertain factors brought by manual movement. When moving the second moving rod 212, the moving rod 212 drives the sliding member 207 to slide on the second slide rail 206, and the gear 210 rolls on the rack 205. When moving the entire clamping mechanism and needing to fix it at a certain position, the gear 210 is relied on to be clamped at the corresponding position of the rack 205, thereby fixing the entire clamping mechanism and avoiding the continuous sliding of the entire clamping mechanism, so that the position where the head needs to be clamped cannot be positioned.

[0036] The second sliding mechanism further includes a second fixing groove 204. The second slide rail 206 is arranged in the second fixing groove 204, and the rack 205 is arranged on the side of the second fixing groove 204. The rack 205 is also located on the side of the second slide rail 206. This enables the second sliding mechanism to play the role of fixing the entire clamping mechanism by relying on the rack 205 and the gear 210 arranged on the side.

[0037] As Figure 4 shown in the figure, in addition to the first slide rail 214, the first sliding mechanism further includes a first fixing groove 213. The first slide rail 214 is arranged in the first fixing groove 213, and the first moving rod 215 is slidably arranged on the first slide rail 214. When moving the clamping mechanism, the first moving rod 215 moves back and forth on the first slide rail 214 so that the clamping mechanism reaches the position where the head needs to be clamped.

[0038] As Figure 5 shown in the figure, the clamping mechanism at least includes a connecting rod 219, a first moving rod 215 and a second moving rod 212 respectively arranged on both sides of the connecting rod 219, and a first clamping member 2171 and a second clamping member 2172 respectively arranged on the first moving rod 215 and the second moving rod 212; the first moving rod 215 is slidably arranged on the first slide rail 214, and the second moving rod 212 is connected to the gear 210. By moving the second moving rod 212, the second moving rod 212 is driven to move on the second slide rail 206.

[0039] In some embodiments, a second electric push rod 2161 is provided between the first clamping member 2171 and the first moving rod 215, and a third electric push rod is provided between the second clamping member 2172 and the second moving rod 212. By providing the electric push rods, the first clamping member 2171 and the second clamping member 2172 can be accurately pushed to appropriate positions, avoiding excessive manual pushing that may cause the first clamping member 2171 and the second clamping member 2172 to contact the wound on the head.

[0040] In some embodiments, to make the patient's head more comfortable when being clamped, a comfort pad 218 is respectively provided on the skin contact surfaces of the first clamping member 2171 and the second clamping member 2172. When the first clamping member 2171 and the second clamping member 2172 contact the corresponding positions on the head, the comfort pad 218 can prevent the relatively hard first clamping member 2172 and the second clamping member 2172 from bruising the patient's head skin.

[0041] As Figure 6 、 7 shown, the mounting mechanism 3 includes a bottom plate 306, side plates 301, a fixing plate 305, threaded holes 302, threaded rods 303, and handles 304. The side plates 301 connect the base 1 and the bottom plate 306. The threaded holes 302 are provided in the middle of the bottom plate 306. The threaded rods 303 are disposed through the threaded holes 302. The fixing plate 305 is fixed to the top of the threaded rods 303, and the handles 304 are fixed to the bottoms of the threaded rods 303. When used on a hospital bed, by rotating the handle 304, the threaded rods 303 rotate in the threaded holes 302, driving the fixing plate 305 to move closer to the base 1, clamping the bed board of the hospital bed between the base 1 and the fixing plate 305, and using the fixing plate 305 and the base 1 to mount and fix the entire head support on the hospital bed. When it is necessary to remove the entire head support, by rotating the handle 304 in the reverse direction, the threaded rods 303 are rotated, causing the fixing plate 305 to move away from the base 1, enabling the bed board of the hospital bed to disengage from between the base 1 and the fixing plate 305, thereby removing the entire head support.

[0042] In summary, the head bracket of the present utility model comprises an adjustment mechanism and a clamping mechanism. After the patient's head leans on the headrest plate, by moving the clamping mechanism, the first moving rod slides on the first slide rail, and the second moving rod slides on the second slide rail, thereby driving the first clamping member and the second clamping member to move at different positions of the head, so as to flexibly adjust the clamping position of the head. Further, the second sliding mechanism in the adjustment mechanism at least comprises a second slide rail, a rack, a gear, and a sliding member sliding on the second slide rail. When the clamping structure is moved, the whole sliding member slides on the second slide rail, and through the cooperation and meshing of the gear and the rack, the second moving rod can be flexibly fixed at a certain position, avoiding the continuous sliding of the whole clamping mechanism, and thus unable to clamp and fix the head at a fixed position. By using the head bracket of the present utility model, the clamping mechanism can be flexibly adjusted to an appropriate position on the head, avoiding bruising the wound on the patient's head.
