Description

technical field

[0001] The invention belongs to the technical field of fixing devices, and in particular relates to a novel head fixing device for ophthalmic examination. Background technique

[0002] Chinese patent (publication number CN208598365U) discloses a head fixing device for ophthalmic examination, including a bottom plate, etc.; wheels are installed at the four corners of the bottom of the bottom plate by bolts, and a lifting device is arranged in the middle of the bottom of the bottom plate. There are fixing devices on the lifting parts.

[0003] The advantage of this utility model is that the height of the fixing device is adjusted by the lifting device, and the patient's head is fixed by the fixing device, thereby achieving the effect of conveniently checking the patient's eyes without affecting the inspection.

[0004] However, due to the relatively simple structure of the fixing device, the patient's head can still move after being fixed, so that the fixing e...

Examples

Embodiment 1

[0023] see Figure 1-Figure 3 , the present invention provides a technical solution: a novel ophthalmic examination head fixation device, comprising a support base 4, a second electric telescopic rod 5 is welded in the middle of the upper surface of the support base 4, and the top end of the second electric telescopic rod 5 is arranged Fixed mechanism 6 is arranged and fixed mechanism 6 comprises drive motor 61, and the output end of drive motor 61 is welded with the spacing base 65 of rectangular parallelepiped structure, and the top of spacing base 65 is provided with fixed base 67, and the middle part of the lower surface of fixed base 67 is welded limited position. Sliding plate 66, the limit base 65 is provided with the limit chute 62 corresponding to limit slide plate 66, and the two ends of the lower surface of fixed base 67 are also provided with the third limit plate 698 corresponding to limit base 65, The middle part of the upper surface of the fixed base 67 is provi...

Embodiment 2

[0031] On the basis of Embodiment 1, in order to make the movement of the fixing device more convenient, in this embodiment, preferably, the two ends of the support base 4 are fixed with the first electric telescopic rod 3 by bolts, and the bottom of the first electric telescopic rod 3 A ground wheel 2 is provided at the end, and a first limit through hole 7 corresponding to the ground wheel 2 is opened on the support base 4;

[0032] In order to make the use of the ground wheel 2 more reliable, in this embodiment, preferably, the top of the ground wheel 2 is fixedly connected with the first electric telescopic rod 3 by welding, and the lower surface of the support base 4 is provided with an anti-slip backing plate 1 to prevent slipping. Both ends of the backing plate 1 are provided with a second limiting through hole 8 corresponding to the ground wheel 2;

[0033] When in use, the ground wheel 2 is used to move the fixing device, making it more convenient for the user to use ...
