Technical Field

[0001] The present application relates to the field of optometry head detection, and in particular to an optometry head detection device. Background Art

[0002] An optometrist is a device that examines the convergence of light after it enters the eye. It uses emmetropia as a standard and measures the difference in vergence between the examined eye and the emmetropia eye. Over time, optometrist readings may deviate, so regular testing is necessary to extend the life of the optometrist.

[0003] In the related art, such as the Chinese patent publication number CN210400799U, a detection device for an optometrist is disclosed, including a base, a clamping mechanism, a connecting plate and a detection device body installed on the base. The bottom of the base is provided with a placement groove, and the bottom of the placement groove is provided with a linear slide rail along the width direction of the base. The detection device body is provided on the linear slide rail. The connecting plate is fixedly installed between the base and the clamping mechanism. The clamping mechanism includes a top plate and a clamping member. The top of the top plate is provided with a threaded through hole vertically downward, and the top of the clamping member is provided with a mounting hole. A locking bolt is provided in the mounting hole, and the locking bolt passes through the mounting hole and is threadedly connected between the threaded through hole. The clamping member is provided with a clamping groove for clamping the mounting ring groove on the side away from the top plate.

[0004] Regarding the above-mentioned related technologies, the inventor believes that this detection device has a linear slide rail along the width direction of the base. If the model of the optometrist head is changed, the height of the detector cannot be aligned with the optometrist head, and the detection device needs to be replaced, which is relatively inconvenient and there is still room for improvement. Utility Model Content

[0005] In order to improve the problem that when replacing the optometrist head model, the detector height cannot be aligned with the optometrist head and the detection device needs to be replaced, which is quite inconvenient, the present application provides an optometrist head detection device.

[0006] The present application provides an optometry head detection device that adopts the following technical solutions:

[0007] A device for detecting an optometrist head includes a detection frame and a detection device body, wherein the detection device body is connected to the detection frame in a sliding manner in the horizontal direction of the detection frame, and further includes a vertical movable component, wherein the detection frame includes two vertical rods, and the vertical movable component includes a first slide rail and a movable bracket for mounting the optometrist head, wherein the number of the first slide rails is two, and the two first slide rails are arranged on the two vertical rods in a one-to-one correspondence, and the first slide rails are arranged along the height direction of the detection frame, and the two ends of the movable bracket are respectively connected to the first slide rails in a sliding manner.

[0008] By adopting the above technical solution, the optometrist head is moved in the height direction of the detection frame by sliding the movable bracket along the first slide rail, so that when the height of the detection device body cannot be aligned with the optometrist head, the height of the optometrist head can be adjusted, so that the detection device body is aligned with the optometrist head. There is no need to replace the detection device, and it is adaptable to various models of optometrist heads, thereby improving the versatility of the optometrist head detection device.

[0009] Optionally, the vertical moving assembly includes a first screw, the detection frame includes a cross bar, the two ends of the cross bar are respectively fixedly connected to the two vertical bars, the first screw is rotatably connected to the movable bracket and is fixedly connected to the movable bracket in the height direction of the detection frame, and the first screw is threadedly connected to the cross bar.

[0010] By adopting the above technical solution, the first screw drives the movable bracket to slide along the height direction of the detection frame. There is a certain friction resistance between the first screw and the movable bracket. Compared with direct sliding on the first slide rail, the degree of fixation between the two is higher, making the sliding of the movable bracket easier to control, thereby improving the precision and stability of the adjustment of the optometrist head along the height direction of the detection frame.

[0011] Optionally, the first screw rod extends to a side of the cross bar away from the movable bracket, and the vertical moving assembly further includes a first adjustment handle, which is fixedly connected to an end of the first screw rod away from the movable bracket.

[0012] By adopting the above technical solution, the first screw is driven to rotate synchronously by the first adjustment handle, the rotation radius is larger, and the force required to achieve the same rotation speed is smaller, thereby improving the convenience of users in adjusting the height of the optometrist head.

[0013] Optionally, the first adjustment handle is provided with an embedding groove for installing the first screw on the side close to the first screw, and the inner wall of the embedding groove is provided with a connecting block. The first screw is provided with a clamping groove on the side close to the first adjustment handle, and the connecting block is filled in the clamping groove. The first adjustment handle is provided with a bolt, and the bolt passes through the first adjustment handle and is threadedly connected to the first screw.

[0014] By adopting the above technical solution, the setting of the bolt connects the first adjustment handle and the first screw in the height direction of the detection frame, so that the first adjustment handle is not easily disjointed from the first screw. On the other hand, the setting of the connecting block and the clamping groove realizes the clamping between the first adjustment handle and the first screw, so that when the user turns the first adjustment handle, the first screw is simultaneously driven to rotate, thereby improving the stability of the first adjustment handle driving the first screw.

[0015] Optionally, a limiting plate is provided on the side of the first slide rail away from the cross bar, and when the movable bracket moves along the first track toward the side away from the cross bar, the movable bracket abuts against the side of the limiting plate close to the cross bar.

[0016] By adopting the above technical solution, when the mobile bracket moves along the first track toward the detector, the mobile bracket abuts against the side of the limit plate close to the cross bar, thereby limiting the moving distance of the mobile bracket and preventing the mobile bracket from continuing to move, avoiding the risk of collision between the optometrist head and the detection device body, and improving the safety of the optometrist head detection.

[0017] Optionally, the vertical moving assembly further includes a first hexagonal knob, which is threadedly connected to the moving bracket, and the screw of the first hexagonal knob presses against the first slide rail to fix the moving bracket.

[0018] By adopting the above technical solution, when the mobile bracket moves to the required position, the first hexagonal knob is rotated, and the screw of the first hexagonal knob is pressed against the first slide rail, so that the friction between the first slide rail and the mobile bracket is increased, and the sliding of the mobile bracket is further made easier to control, thereby improving the precision and stability of the adjustment of the optometrist head along the height direction of the detection frame.

[0019] Optionally, a mounting seat is provided on the side of the movable bracket close to the first screw, a circular groove is provided on the side of the mounting seat close to the movable bracket, a through hole is provided at the bottom of the circular groove for the first screw to pass through, and a limit block is provided at one end of the first screw close to the movable bracket, and the limit block abuts against the side wall of the circular groove close to the first screw.

[0020] By adopting the above technical solution, the limit block is fixedly connected to the first screw only, abutting against the side wall of the circular groove close to the first screw and the side of the movable bracket close to the cross bar, thereby realizing the rotational connection between the first screw and the movable bracket. On the other hand, the setting of the limit block also limits the relative movement of the first screw and the movable bracket along the height direction of the detection frame, so that the rotation of the first screw synchronously drives the movable bracket to move along the height direction of the detection frame, thereby improving the stability of the adjustment of the optometry head along the height direction of the detection frame.

[0021] Optionally, the detection frame also includes a base, which is perpendicular to the plane of the cross bar and the vertical bar and is fixedly connected to the ends of the two vertical bars away from the cross bar. The base is provided with a movable platform, and the movable platform is slidably connected to the base along the length direction of the cross bar. A horizontal movable component is provided on the movable platform, and the horizontal movable component includes a mounting plate and two third slide rails, and the two third slide rails are fixedly connected to the movable platform perpendicular to the length direction of the cross bar. Both sides of the mounting plate are slidably connected to the two third slide rails in a one-to-one correspondence, and the detection device body is fixedly connected to the mounting plate.

[0022] By adopting the above technical solution, the detection device body is synchronously driven to move along the length direction of the cross bar by sliding the mobile platform on the base, so that when the detection device body cannot be aligned with the optometrist head along the length direction of the cross bar, the position of the detection device body along the length direction of the cross bar can be adjusted so that the detection device body is aligned with the optometrist head along the length direction of the cross bar. On the other hand, the detection device body is synchronously driven to move along the length direction of the vertical cross bar by sliding the mounting plate on the third slide rail along the length direction of the vertical cross bar, so that when the detection device body cannot be aligned with the optometrist head along the length direction of the vertical cross bar, the position of the detection device body along the length direction of the vertical cross bar can be adjusted so that the detection device body is aligned with the optometrist head along the length direction of the vertical cross bar, thereby improving the versatility of the optometrist head detection device.

[0023] Optionally, a reinforcing rib is fixedly connected to a side of the vertical rod away from the horizontal rod, and the reinforcing rib is fixedly connected to the base.

[0024] By adopting the above technical solution, the setting of the reinforcing ribs strengthens the connection structure between the base and the two vertical rods. When the two vertical rods of the detection frame tend to tilt, the reinforcing ribs provide the vertical rods with anti-tilting support force, so that the two vertical rods of the detection frame remain in a vertical state when connected to the base, thereby improving the stability of the optometry head detection device.

[0025] Optionally, the detection frame is provided with a base.

[0026] By adopting the above technical solution, the rubber material of the base enhances the friction between the detection frame and the placement surface, making it difficult for the optometrist detection device to shift or tip over when it is in a shaking state or subjected to thrust, thereby improving the stability of the optometrist detection device.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The optometrist head is moved along the height direction of the detection frame by sliding the movable bracket along the first slide rail, so that the height of the optometrist head can be adjusted, thereby improving the versatility of the optometrist head detection device;

[0029] 2. The first screw is driven to rotate synchronously by the first adjustment handle, which requires less force to achieve the same rotation speed, thereby improving the convenience of users in adjusting the height of the optometrist head;

[0030] 3. The moving distance of the movable bracket is limited by the limit plate to avoid collision between the optometrist head and the detection device body, thereby improving the safety of optometrist head detection. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The following is combined with Figure 1-5 This application is described in further detail.

[0038] The embodiment of the present application discloses an optometry head detection device.

[0039] Reference Figure 1 The optometrist testing device includes a testing frame 1, a testing device body 2, a vertical movement assembly 3, and a horizontal movement assembly 4. The vertical movement assembly 3 is mounted on the testing frame 1 to accommodate the optometrist and allows for movement along the height of the testing frame 1. The testing device body 2 is mounted on the horizontal movement assembly 4, which is mounted on the testing frame 1 to adjust the position of the testing device body 2 relative to the testing frame 1 along its width.

[0040] Reference Figure 1The detection frame 1 includes a horizontal bar 11, a base 12 and two vertical bars 13. The two ends of the horizontal bar 11 are fixedly connected to the two vertical bars 13 respectively, and the two ends of the base 12 are fixedly connected to the ends of the two vertical bars 13 away from the horizontal bar 11. The vertical moving assembly 3 includes a mobile bracket 31, two first slide rails 33 and a first screw 32. The two first slide rails 33 are fixedly connected to the opposite sides of the two vertical bars 13 in a one-to-one correspondence. The two ends of the mobile bracket 31 are slidably connected to the two first slide rails 33 respectively, so that the mobile bracket 31 can move along the height direction of the detection frame 1. An optometrist is hung on the mobile bracket 31 for the detection device body to perform detection.

[0041] Reference Figure 1 , a first hexagonal knob 311 is threadedly connected to the movable bracket 31, wherein the number of the first hexagonal knobs 311 is two, and the two first hexagonal knobs 311 are respectively located at the two ends of the movable bracket 31. When the first hexagonal knob 311 is rotated, the screw of the first hexagonal knob 311 passes through the movable bracket 31 and is pressed against the first slide rail 33, and the movement of the movable bracket 31 along the height direction of the detection frame 1 is locked. The end of the first slide rail 33 away from the cross bar 11 is fixedly connected to the limit plate 312. When the movable bracket 31 moves to the side of the first slide rail 33 close to the limit plate 312, the movable bracket 31 abuts against the limit plate 312, preventing the movable bracket 31 from continuing to move to the side of the first slide rail 33 away from the cross bar 11.

[0042] Reference Figure 2 and Figure 3 , a mounting base 323 is fixedly connected to the mobile bracket 31. The mounting base 323 has a circular groove 3231 on the side close to the mobile bracket 31. A through hole 3232 is provided at the bottom of the circular groove 3231, and the through hole 3232 and the circular groove 3231 are coaxially arranged. The first screw 32 is passed through the through hole 3232 and extends into the circular groove 3231 to realize the rotational connection between the first screw 32 and the mobile bracket 31. The end of the first screw 32 close to the mobile bracket 31 is fixedly connected to the limiting block 321, and the limiting block 321 abuts against the bottom of the circular groove 3231, so that the first screw 32 and the mounting base 323 are relatively fixed in the height direction of the detection frame 1.

[0043] Reference Figure 1 and Figure 4The other side of the first screw rod 32 is threadedly connected to the crossbar 11. Rotating the first screw rod 32 drives the movable bracket 31 to move along the length of the first screw rod 32. The distal end of the first screw rod 32 is fixedly connected to a first adjustment handle 322. The side of the first adjustment handle 322 near the first screw rod 32 has an embedding groove 3223. A connecting block 3221 is fixed to the inner wall of the embedding groove 3223. The first screw rod 32 has a snap-fitting groove 324. The first screw rod 32 and the first adjustment handle 322 are snap-fitted. Rotating the first adjustment handle 322 drives the first screw rod 32 to rotate synchronously. The first adjustment handle 322 also has a bolt 3222, which passes through the first adjustment handle 322 and is threadedly connected to the first screw rod 32.

[0044] Reference Figure 1 The base 12 includes two short rods 121 and two second slide rails 122. The two short rods 121 are fixedly connected to the ends of the two vertical rods 13 away from the cross bar 11 in a one-to-one correspondence. The two ends of the second slide rail 122 are fixedly connected to the two short rods 121. The mobile platform 1221 and the two second slide rails 122 are both slidably connected, so that the mobile platform 1221 can move along the length direction of the cross bar 11. The two short rods 121 are fixedly connected to the reinforcing ribs 14, and the reinforcing ribs 14 are fixedly connected to the vertical rods 13 to enhance the connection strength between the base 12 and the vertical rods 13.

[0045] Reference Figure 1 The movable platform 1221 is threadedly connected to the second screw rod 1222. The two ends of the second screw rod 1222 are rotatably connected to the two short rods 121 in a one-to-one correspondence. Rotating the second screw rod 1222 drives the movable platform 1221 along the length of the second slide rail 122. One end of the second screw rod 1222 passes through the short rod 121 and extends to the side of the short rod 121 away from the movable platform 1221. One end of the second screw rod 1222 is fixedly connected to the second adjustment handle 1223. Rotating the second adjustment handle 1223 drives the second screw rod 1222 to rotate synchronously.

[0046] Reference Figure 1 The mobile platform 1221 is threadedly connected with a second hexagonal knob 1224. When the second hexagonal knob 1224 is rotated and the screw of the second hexagonal knob 1224 passes through the mobile platform 1221 and is pressed against the second slide rail 122, the movement of the mobile platform 1221 along the length direction of the crossbar 11 is locked.

[0047] Reference Figure 5The horizontal movement assembly 4 includes a mounting plate 41, a third screw 42, and two third slide rails 43. The two third slide rails 43 are fixedly connected to the mobile platform 1221. The mounting plate 41 and the two third slide rails 43 are slidably connected, allowing the mounting plate 41 to move along the length of the third slide rails 43. A connecting plate 45 is fixedly connected between the two third slide rails 43. There are two connecting plates 45, and the ends of the connecting plates 45 are respectively connected to the ends of the two third slide rails 43 in the same direction.

[0048] Reference Figure 5 The mounting plate 41 is threadedly connected to the third screw 42. The two ends of the third screw 42 rotate in a one-to-one correspondence with the two connecting plates 45. Rotating the third screw 42 drives the mounting plate 41 along the length of the third slide rail 43. One end of the third screw 42 extends through the connecting plate 45 to the side of the connecting plate 45 away from the mounting plate 41. One end of the third screw 42 is fixedly connected to the adjustment knob 421. Rotating the adjustment knob 421 causes the third screw 42 to rotate synchronously.

[0049] Reference Figure 5 The mounting plate 41 is threadedly connected with a third hexagonal knob 44. When the third hexagonal knob 44 is rotated and the screw of the third hexagonal knob 44 passes through the mounting plate 41 and is pressed against the third slide rail 43, the movement of the mounting plate 41 along the length direction of the third slide rail 43 is locked.

[0050] Reference Figure 1 The side of the detection frame 1 away from the cross bar 11 is fixedly connected with a foot 15, so that the optometrist detection mechanism is stable on the placement plane.
