[0031] This utility model proposes an optometry device, which aims to achieve a detachable connection between the first housing and the second housing through a connecting component, allowing the optometric components to be removed from the optometry box for easy maintenance of the optometry device; at the same time, the connecting component stably connects the first housing and the second housing together, ensuring the connection stability and strength between the two, and also guaranteeing the stability of the optometry device in use.

[0032] Please see Figures 1 to 5 In one embodiment of this utility model, the optometry device 10 includes:

[0033] Base 1;

[0034] The optometry assembly 2 includes an optometry box 21 and an optometer 22. The optometry box 21 includes a first housing 211 and a second housing 212. The first housing 211 is mounted on the base 1, and the second housing 212 is detachably connected to the first housing 211.

[0035] The connecting component 3 includes a first connector 31 and a second connector 32. The first connector 31 is installed on the first housing 211, and the second connector 32 is installed on the first housing 211. The first connector 31 is detachably connected to the second connector 32.

[0036] In this embodiment, the optometry device 10 includes a base 1 and an optometry component 2. The optometry component 2 includes an optometry box 21 and an optometer 22. The optometry box 21 includes a first housing 211 and a second housing 212. The first housing 211 is mounted on the base 1, while the second housing 212 is detachably mounted on the side of the first housing 211 facing away from the base 1. A receiving cavity 21a is formed between the first housing 211 and the second housing 212, and the optometer 22 is disposed within the receiving cavity 21a. It should be noted that the optometer 22 can be stably mounted within the receiving cavity 21a using screws or the like, thus facilitating assembly and disassembly. Furthermore, it should be noted that the optometer 22 is provided with multiple optical components. The optometer 22 is prior art, and this application does not limit its use.

[0037] Specifically, in order to improve the connection stability between the first housing 211 and the second housing 212, the optometry device 10 also includes a connection component 3. The connection component 3 includes a first connector 31 and a second connector 32. The first connector 31 is installed on the first housing 211, and the second connector 32 is installed on the second housing 212. The first connector 31 is detachably connected to the second connector 32, so that the second housing 212 can be stably installed on the first housing 211, thereby ensuring the connection stability between the first housing 211 and the second housing 212, and thus ensuring the stability of the optometry device 22 in use.

[0038] In one implementation, please refer to Figures 1 to 4The second connector 32 has a through slot 321 on the side opposite to the second housing 212. The first connector 31 includes a mounting bracket 311, a driving member 312, and a plug 313. The mounting bracket 311 is mounted on the first housing 211, and the driving member 312 is mounted on the mounting bracket 311 and driven to connect to the plug 313, so that the plug 313 is inserted into the through slot 321, thereby realizing the connection of the first connector 31 to the second connector 32, so as to stably install the second housing 212 on the first housing 211.

[0039] In this embodiment, to facilitate the connection between the first connector 31 and the second connector 32, the second connector 32 is provided with a through groove 321 on the side away from the second housing 212. Meanwhile, the first connector 31 includes a mounting bracket 311, a driving member 312, and a plug 313. The mounting bracket 311 is mounted on the first housing 211, and the driving member 312 is mounted on the mounting bracket 311 and driven to connect to the plug 313, so as to drive the plug 313 to be inserted into the through groove 321. In this way, the second housing 212 can be stably mounted on the first housing 211. At the same time, when the driving member 312 drives the plug 313 away from the through groove 321, the first connector 31 and the second connector 32 can be separated, so that the second housing 212 can be removed from the first housing 211, and then the optometer 22 can be stably installed in the receiving cavity 21a.

[0040] It should be noted that the through groove 321 is U-shaped.

[0041] In one implementation, please refer to Figure 3 and Figure 4 The driving component 312 includes a rotating handle 3121, a connecting rod 3122, and a driving rod 3123. The rotating handle 3121 is rotatably connected to the mounting bracket 311 and is located on the side of the mounting bracket 311 opposite to the first housing 211. The rotating handle 3121 is driven to the driving rod 3123. The driving rod 3123 passes through the mounting bracket 311 on the side opposite to the rotating handle 3121 and is driven to the connecting rod 3122. The connecting rod 3122 is driven to the plug 313. Through the cooperation between the rotating handle 3121, the driving rod 3123, and the connecting rod 3122, the plug 313 can be stably inserted into the through slot 321 or stably removed from the through slot 321.

[0042] In this embodiment, the driving component 312 includes a rotating handle 3121, a connecting rod 3122, and a driving rod 3123. The rotating handle 3121 is rotatably connected to the mounting bracket 311 and is located on the side of the mounting bracket 311 opposite to the first housing 211. The rotating handle 3121 is driven to connect to the driving rod 3123. That is, while the rotating handle 3121 is rotating, it also drives the driving rod 3123 to move. At the same time, the driving rod 3123 passes through the mounting bracket 311 on the side opposite to the rotating handle 3121 and is driven to connect to the connecting rod 3122. The connecting rod 3122 is driven to connect to the plug 313. Thus, under the drive of the rotating handle 3121, the plug 313 is smoothly moved through the linkage of the driving rod 3123 and the connecting rod 3122, so that the plug 313 can be stably inserted into the through slot 321 or stably removed from the through slot 321.

[0043] In one implementation, please refer to Figure 4 The rotating handle 3121 has an eccentric hole on the side facing the mounting bracket 311, and the drive rod 3123 is connected to the eccentric hole at the end away from the connecting rod 3122. The mounting bracket 311 has a sliding groove 3111 for the drive rod 3123 to move.

[0044] In this embodiment, to facilitate the connection between the rotating handle 3121 and the drive rod 3123, the rotating handle 3121 has an eccentric hole on the side facing the mounting bracket 311. The end of the drive rod 3123 away from the connecting rod 3122 is connected to the eccentric hole. That is, the drive rod 3123 rotates cyclically under the drive of the rotating handle 3121, driving the plug 313 to be inserted into the through slot 321, or enabling the plug 313 to be stably moved out of the through slot 321. At the same time, the mounting bracket 311 also has a sliding groove 3111 for the drive rod 3123 to move. Thus, under the drive of the rotating handle 3121, the drive rod 3123 moves within the sliding groove 3111, smoothly driving the plug 313 to move. It should be noted that the sliding groove 3111 is semi-circular.

[0045] In one implementation, please refer to Figure 4 The first connector 31 also includes a guide 314, which is installed on the side of the mounting bracket 311 away from the rotating handle 3121. The guide 314 has a guide groove for the connecting rod 3122 to slide. Under the guidance of the guide 314, the connecting rod 3122 can be smoothly driven to insert and move.

[0046] In one implementation, please refer to Figures 3 to 5The optometry device 10 also includes a locking component 4, which is installed on the mounting bracket 311 and located on one side of the rotating handle 3121 to fix or loosen the rotating handle 3121, so as to ensure that the plug 313 can be smoothly inserted into the second connector 32, thereby ensuring the stable connection between the first housing 211 and the second housing 212.

[0047] In one implementation, please refer to Figures 3 to 5 The locking assembly 4 includes a fixed base 41, a locking rod 42, a limiting rod 43, and an elastic element 44. The fixed base 41 is mounted on the mounting bracket 311 and has two oppositely arranged guide seats 411. The locking rod 42 passes between the two guide seats 411 in sequence. The limiting rod 43 is located on the side of the locking rod 42 near the rotating handle 3121. The elastic element 44 is sleeved on the locking rod 42. One side of the elastic element 44 abuts against the limiting rod 43, and the other side of the elastic element 44 abuts against the guide seat 411 away from the rotating handle 3121.

[0048] In this embodiment, the locking assembly 4 includes a fixed base 41, a locking rod 42, a limiting rod 43, and an elastic element 44. The fixed base 41 is mounted on the mounting bracket 311. The fixed base 41 is provided with two oppositely arranged guide seats 411, and the locking rod 42 is sequentially inserted between the two guide seats 411. At the same time, the limiting rod 43 is located on the side of the locking rod 42 near the rotating handle 3121. The elastic element 44 is sleeved on the locking rod 42. One side of the elastic element 44 abuts against the limiting rod 43, and the other side of the elastic element 44 abuts against the guide seat 411 away from the rotating handle 3121. Therefore, when the locking rod 42 is pushed, the locking rod 42 rebounds under the drive of the elastic element 44, and can then be stably inserted into the rotating handle 3121, thereby effectively preventing the rotating handle 3121 from rotating under the action of other external forces, so as to avoid the plug 313 from being moved out of the second connector 32, thereby preventing the separation between the first housing and the second housing 212.

[0049] In one implementation, please refer to Figure 3 The outer peripheral wall of the rotating handle 3121 is provided with a plurality of anti-slip protrusions 3121a spaced apart, and a gap 3121b is formed between two adjacent anti-slip protrusions 3121a. The locking rod 42 is provided with a plug 421 at one end near the rotating handle 3121. The plug 421 is conical. This arrangement makes it easy for the locking rod 42 to stably lock the rotating handle 3121.

[0050] In this embodiment, the outer peripheral wall of the rotating handle 3121 is provided with a plurality of anti-slip protrusions 3121a spaced apart. By providing a plurality of anti-slip protrusions 3121a, it is convenient for the operator to rotate the rotating handle 3121. At the same time, a gap 3121b is formed between two adjacent anti-slip protrusions 3121a, and the locking rod 42 is provided with a plug 421 at one end near the rotating handle 3121. The plug 421 is conical, so that the plug 421 can be stably inserted into the gap 3121b, thereby securely locking the rotating handle 3121.

[0051] In one implementation, please refer to Figure 1 The connecting components 3 are provided in multiple ways, and the multiple connecting components 3 are spaced apart at the connection between the first housing 211 and the second housing 212. By providing multiple connecting components 3, the first housing 211 and the second housing 212 can be stably connected together, ensuring the connection stability and connection strength between the two, and also ensuring the stability of the use of the optometer 22.

[0052] In one implementation, please refer to Figure 2 The first housing 211 has a plurality of spaced limiting cylinders 2111 on the side facing the second housing 212, and each limiting cylinder 2111 has a limiting hole. The second housing 212 has a plurality of spaced limiting posts 2121 on the side facing the first housing 211, and each limiting post 2121 is inserted into each limiting hole. Through the cooperation between the limiting cylinders 2111 and the limiting posts 2121, the second housing 212 can be further stably connected to the first housing 211.
