The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.
[0028] Example 1
[0029] Reference Figure 1 to Figure 5, is the first embodiment of the utility model, which provides an adjustment and fixing mechanism, including an adjustment component 100, which includes a bracket 101, a rotating column 102 arranged on the side wall of the bracket 101, and an adjustment component 103 arranged on the rotating column 102; and, two rotating columns 102 are arranged on the inner side wall of the bracket 101, and the rotating columns 102 are symmetrically arranged on both sides of the bracket 101, and a buckle 103a is arranged on the side of the rotating column 102 away from the bracket 101, and a gear 103b is arranged on the side of the rotating column 102 away from the buckle 103a.
[0030] Furthermore, the gear 103b is disposed inside the bracket 101, and a tooth plate 103b-1 is disposed inside the bracket 101, and the tooth plate 103b-1 cooperates with the gear 103b.
[0031] Specifically, rotating columns 102 are disposed inside both sides of the bracket 101 , and the rotating columns 102 are disposed throughout the inside and outside of the bracket 101 . Two rotating columns 102 are disposed and are symmetrically disposed on both sides of the bracket 101 .
[0032] Furthermore, a buckle 103 a is provided on the side of the rotating column 102 away from the bracket 101 , and the buckle 103 a can be fixed to prevent the connection on the rotating column 102 from falling off.
[0033] Furthermore, the bracket 101 is configured to have one end in an arc shape and two sides in a horizontal shape.
[0034] Furthermore, a gear 103b is provided on the rotating column 102 inside the bracket 101. The bracket 101 is hollow, and a tooth plate 103b-1 is provided at the bottom inside the bracket 101. The tooth plate 103b-1 is limited by the internal size of the bracket 101, so that the tooth plate 103b-1 can only move along the horizontal section of the bracket 101.
[0035] Specifically, by rotating the rotating column 102, the gear 103b on the rotating column 102 rotates and cooperates with the tooth plate 103b-1, thereby driving the movement of the tooth plate 103b-1, thereby adjusting the position of the tooth plate 103b-1, and a fixed object can be connected to the rear end of the tooth plate 103b-1, and the tightness of the back of the patient's head can be fixed by controlling the adjustment component 103.
[0036] Example 2
[0037] Reference Figure 1 to Figure 6, which is the second embodiment of the utility model. Different from the previous embodiment, it also includes a fixing assembly 200 including a second fixing bracket 202 fixedly connected to the tooth plate 103b-1, and a pad 202a is provided on the side of the second fixing bracket 202 away from the bracket 101. The first fixing bracket 201 is provided with two fixing frames 201a, and an angle is formed between the two fixing frames 201a. The fixing component 203 includes two fixing columns 203a arranged on the bracket 101, and the fixing columns 203a are symmetrically arranged on both sides of the bracket 101, and a fixing buckle 203a-1 is provided on the fixing column 203a.
[0038] Furthermore, the fixing buckle 203a-1 is arranged in an arc shape on the side away from the pad 202a, and a fixing plate 203b is arranged on the side of the bracket 101 close to the pad 202a. The fixing plate 203b is arranged on the side of the bracket 101 away from the rotating column 102, and a connecting rod 203b-1 is arranged through the fixing plate 203b, and a movable block 203b-2 is connected to one side of the connecting rod 203b-1. A connecting plate 203b-3 is arranged on the movable block 203b-2 and is connected to the fixing buckle 203a-1, a telescopic spring 203b-5 is arranged between the movable block 203b-2 and the fixed plate 203b, and a baffle 203b-4 is arranged on the side of the connecting rod 203b-1 away from the movable block 203b-2.
[0039] Furthermore, the first fixing bracket 201 is provided with two fixing frames 201a, and a fixed telescopic distance is set between the fixing frames 201a, one of the fixing frames 201a is set to be fixedly connected with the rotating column 102, and when the rotating column 102 rotates, one of the fixing frames 201a is driven to rotate, and the other fixing frame 201a is fixed at an angle with the rotating column 102, and the side of the fixing frame 201a close to the rotating column 102 that contacts each other is set to be inclined, and when the angle between the two fixing frames 201a reaches a certain size, it will be stuck, so that the angle formed between the two fixing frames 201a is fixed to the top of the patient's head.
[0040] Furthermore, the second fixing bracket 202 is connected to the toothed plate 103b-1, and the first fixing bracket 201 is rotated to drive the gear 103b on the rotating column 102 to rotate, so that the toothed plate 103b-1 drives the displacement of the second fixing bracket 202, thereby fixing it on the back side of the patient's head.
[0041] Furthermore, a fixing buckle 203a-1 is provided on the fixing column 203a, and the fixing buckle 203a-1 is rotatably connected to the fixing column 203a. The fixing buckle 203a-1 is arranged in an arc shape, and the arc of the fixing buckle 203a-1 contacts the patient's head.
[0042] Furthermore, a connecting rod 203b-1 is provided through the fixed plate 203b, a movable block 203b-2 is connected to the connecting rod 203b-1, a connecting plate 203b-3 is provided on the movable block 203b-2, the connecting plate 203b-3 is provided to contact one end of the fixed buckle 203a-1, and the side of the movable block 203b-2 in contact with the first fixed bracket 201 is provided as an inclined surface.
[0043] Furthermore, the length of the side of the fixing buckle 203a-1 away from the fixing plate 203a is set longer than the side close to the fixing plate 203a, so that only a small push of the movable block 203b-2 can cause the side of the fixing buckle 203a-1 in contact with the patient's head to be displaced significantly.
[0044] Specifically, when the first fixed support 201 is adjusted, the second fixed support 202 can be driven to be displaced. At the same time, when the first fixed support 201 contacts the movable block 203b-2, the connecting rod 203b-1 and the movable block 203b-2 are displaced. At this time, the telescopic spring 203b-5 is contracted, and the connecting plate 203b-3 drives the displacement of the fixing buckle 203a-1, so that the side of the fixing buckle 203a-1 in contact with the patient's head is contracted inward, thereby fixing the top, front and back sides of the patient's head. The bracket 101 can be set to a plastic material, and soft materials can be added inside the bracket 101 to ensure the comfort of the patient when using it.
[0045] Example 3
[0046] Reference Figure 1 to Figure 6 , which is the third embodiment of the utility model, and further provides a locking device. It includes a locking mechanism 300, which is arranged on one side of the fixing plate 203b, and includes a threaded hole 301 arranged on the fixing plate 203b and a locking bolt 302 that penetrates and is arranged on one side of the connecting rod 203b-1 and matches the threaded hole 301, and the locking bolt 302 is arranged to match and connect with the threaded hole 301.
[0047] Furthermore, when the connecting plate 203b-3 on the movable block 203b-2 contacts the fixing buckle 203a-1 and causes the fixing buckle 203a-1 to rotate on the fixing column 203a, the baffle 203b-4 is penetrated by a locking bolt 302 which cooperates with the threaded hole 301 to make the device more firmly fixed.
