Description

Technical Field

[0001] This invention belongs to the field of optical detection technology, specifically a comprehensive optometry analyzer. Background Technology

[0002] A comprehensive optometry analyzer is an instrument primarily used to detect the vertex power, prism power, and axis orientation of cylindrical lenses. It can also print marks on uncut lenses and check whether the lenses are correctly mounted on the frames. It is a relatively common instrument in the field of medical eyeglass fitting.

[0003] When using an optometry analyzer to test lenses, the lens to be tested can be placed on the support frame of the optometry analyzer. Then, the lens holder of the optometry analyzer is pressed down, and the lens is pressed and fixed by the support frame and the lens holder. After that, the position of the lens is manually adjusted and the lens is focused. After focusing, the lens data can be tested by the optometry analyzer.

[0004] When using an optometry analyzer to test the data of eyeglass lenses, a lens clamp and a support frame are needed to compress and support the lenses. However, when using a lens clamp to support the lenses, the contact area between the tips of the clamp and the support frame and the lenses is small, which can cause excessive pressure on certain areas of the lenses, easily scratching them and affecting their use.

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] like Figures 1 to 6 As shown in the embodiment of the present invention, a comprehensive optometry analyzer includes a base 1; a support arm 101 is fixedly connected to the top of the base 1; a detection device 102 is slidably connected to the top of the support arm 101; an operating table 103 is installed on the top of the base 1 and on one side of the support arm 101; a fixed seat 2 is provided on the top of the operating table 103; an adjustment component is provided on the side of the fixed seat 2; a placement groove is opened on the top of the fixed seat 2; and multiple fixing blocks 3 are slidably connected inside the fixed seat 2. The bases 2 are arranged in a circular array; the fixing blocks 3 are set at the corresponding placement slots; the interior of the fixing base 2 is provided with a pull rope 6; two corresponding rotating frames 4 are fixedly connected to the side wall of the fixing base 2; a take-up roller 5 is rotatably connected between the two rotating frames 4; one end of the pull rope 6 is fixedly connected to the interior of the fixing base 2 near the rotating frame 4, and the other end of the pull rope 6 is wound around the take-up roller 5; a rope groove 7 is opened on the side of the fixing block 3 away from the placement slot; the pull rope 6 is in contact with each rope groove 7; the top of the rotating frame 4 is provided with Locking component; During operation, when the lens power needs to be tested, the lens can be placed inside the placement slot. Then, the take-up roller 5 is rotated, causing the take-up roller 5 to pull the pull rope 6. The tightening of the pull rope 6 will pull the fixing block 3 into the placement slot, thus squeezing and fixing the lens. By rotating the take-up roller 5, multiple fixing blocks 3 can be pulled together, making it easier to fix the lens. At the same time, a lens frame slot can be opened on the side of the placement slot for placing a lens frame with the lens to be tested, making the device easier to use. After the lens is placed inside the placement slot and fixed, the position of the fixing seat 2 can be adjusted by adjusting the component, so that the lens can be better focused with the detection mechanism of the machine base 1. The structural design of squeezing and fixing the lens inside the placement slot by the fixing block 3 realizes the function of clamping and fixing the edge of the lens, effectively solving the problem of easy scratching of the lens when using a pressure frame to support the lens. When the lens needs to be removed, the fixing block 3 can be reset sequentially by pulling the spring, so as to facilitate the next test.

[0033] like Figures 1 to 4As shown, the adjustment assembly includes a threaded block 8; the threaded block 8 is fixedly connected to the outer wall of the fixed base 2; a threaded rod 9 is threadedly connected to the threaded block 8; the threaded rod 9 is perpendicular to the outer wall of the support arm 101; a first fixed frame 12 is fixedly connected to the top of the operating table 103; the threaded rod 9 is rotatably connected inside the first fixed frame 12; a guide block 10 is fixedly connected to the side wall of the fixed base 2 opposite to the threaded block 8; a second fixed frame 121 is fixedly connected to the top of the machine base 1; the second fixed frame 121 is symmetrically arranged with the first fixed frame 12; a guide rod 11 is fixedly connected between the second fixed frame 121 and the outer wall of the support arm 101; the guide block 10 is slidably connected to the outer wall of the guide rod 11; the detection device 102 is slidably connected to the support arm 101. At the top position; a push block 104 is fixedly connected to the bottom of the detection device 102, and the push block 104 is slidably connected inside the support arm 101; the sliding of the push block 104 is driven by an electric push rod; during operation, when it is necessary to focus the lens inside the placement slot, the threaded rod 9 can be rotated, and the thread on the surface of the threaded rod 9 engages with the thread inside the threaded block 8, so that the fixed seat 2 slides on the top of the operating table 103, thereby allowing the fixed seat 2 to be adjusted longitudinally. At the same time, the electric push rod can be controlled to drive the push block 104 to slide, thereby allowing the detection device 102 to be adjusted laterally, and thus adjusting the lens position of the detection device 102. This allows the operator to focus the lens without touching it, making lens focusing more convenient.

[0034] like Figure 7 As shown, a rotating handle is fixedly connected inside the take-up roller 5, and the rotating handle passes through the rotating frame 4 and is rotatably connected to the take-up roller 5; a threaded frame 13 is fixedly connected to the outer wall of the fixed base 2; the threaded frame 13 is located at the top of the corresponding rotating frame 4; a locking rod 14 is threadedly connected inside the threaded frame 13; the locking rod 14 is located at the position of the rotating handle of the corresponding take-up roller 5; during operation, when the take-up roller 5 is rotated to tighten the pull rope 6, the locking rod 14 can be rotated, causing the locking rod 14 to move downward in the threaded engagement with the threaded frame 13, thereby squeezing and fixing the rotating handle at the top of the take-up roller 5. This effectively prevents the spring from pulling back the fixing block 3 after the take-up roller 5 is adjusted, thus preventing the take-up roller 5 from being pulled back, resulting in a better fixing effect of the fixing block 3 on the lens.

[0035] like Figure 1 and Figure 8As shown, a cleaning tank 15 is fixedly connected to the outer wall of the operating table 103; a placement rack 20 is slidably connected inside the cleaning tank 15; multiple through holes are opened at the bottom of the placement rack 20; a water outlet is opened on the bottom surface of the cleaning tank 15; a water guide pipe 18 is opened at the top of the cleaning tank 15; multiple spray nozzles 19 are opened at the bottom of the water guide pipe 18, and the spray nozzles 19 are arranged in a linear array at the bottom of the water guide pipe 18; a water pump is installed on the side wall of the operating table 103; the input end of the water pump is connected to a water outlet pipe 16, and the other end of the water outlet pipe 16 is connected to the cleaning tank 15; the output end of the water pump is connected to a water inlet pipe 17, and the other end of the water inlet pipe 17 is guided to the middle of the water guide pipe 18; the sliding of the placement rack 20... The movement is driven by an electric pusher cylinder. During operation, when the lens needs to be inspected, the placement rack 20 can be pushed out first by the electric pusher cylinder, and then the lens can be placed inside the placement rack 20. After placement, the placement rack 20 can be pulled into the cleaning tank 15 by the electric pusher cylinder, and then the water pump can be started to fill the water pipe 18 with water. Then, the water can be sprayed downward through the spray nozzle 19 to clean the surface of the lens, making the surface of the lens cleaner. After the water passes through the placement rack 20, it will fall into the bottom position of the cleaning tank 15 through the through hole, and then be drawn by the water pump and introduced into the position of the water pipe 18 through the water inlet pipe 17, so that the water can be recycled. At the same time, the water outlet pipe 16 can be connected by a flange, so that the water outlet pipe 16 can be quickly disassembled, making it easier to replace dirty water.

[0036] like Figure 4 and Figure 6 As shown, a fixing pad 21 is fixedly attached to the side wall of the fixing block 3; the fixing pad 21 is disposed on the side wall of the fixing block 3 near the placement groove; during operation, when the fixing block 3 squeezes and fixes the lens, the fixing block 3, which is made of rubber, fixes the lens, which can make the contact area between the fixing block 3 and the lens larger, thereby making the fixing block 3 fix the lens better. At the same time, the soft fixing pad 21 contacts the lens, which can effectively prevent the hard fixing block 3 from damaging the lens.

[0037] like Figure 6 As shown, the fixed block 3 is internally rotatably connected with anti-wear wheels 22; the anti-wear wheels 22 are provided at both corners of the side wall of the fixed block 3 away from the placement groove; the anti-wear wheels 22 are located at the corresponding positions of the rope groove 7; during operation, when the fixed block 3 is pushed by tightening the pull rope 6, the anti-wear wheels 22 at the corners of the fixed block 3 can change the sliding friction between the pull rope 6 and the fixed block 3 into rolling friction, thus reducing the wear between the pull rope 6 and the fixed block 3, and effectively preventing excessive wear between the fixed block 3 and the pull rope 6, which could easily cause the pull rope 6 to break.

[0038] like Figure 6 As shown, a positioning rod 23 is fixedly connected to the side wall of the fixed block 3 away from the placement groove; the positioning rod 23 is slidably connected to the inside of the fixed seat 2; during operation, when the fixed block 3 slides inside the fixed seat 2, the positioning rod 23 is restricted by the fixed seat 2, so that the fixed block 3 is less likely to tilt during the sliding process, making the fixed block 3 more stable during the sliding process.

[0039] like Figure 8 As shown, a blocking ball 24 is provided at the bottom of the spray nozzle 19; multiple elastic ropes are connected to the top of the blocking ball 24, and the other end of the elastic ropes is fixed to the inner wall of the spray nozzle 19; during operation, when water enters the water guide pipe 18 through the water inlet pipe 17, the blocking ball 24 makes the water flow more evenly inside the water guide pipe 18, thereby making the amount of water sprayed from each spray nozzle 19 more uniform. At the same time, the blocking ball 24 makes the water spray range larger, thereby making the water spray cleaning effect on the lens better.

[0040] like Figure 4 As shown, a positioning block 25 is fixedly connected to the end of the threaded rod 9; the positioning block 25 is rotatably connected to the inside of the support arm 101; during operation, when the threaded rod 9 rotates, the positioning block 25 is restricted by the support arm 101, which makes the threaded rod 9 more stable during rotation, and makes the effect of the threaded rod 9 pushing the threaded block 8 better.

[0041] like Figure 4 As shown, the positioning block 25 is provided with a plurality of balls 26 on its exterior; the balls 26 are in contact with the sidewalls of the positioning block 25 and the support arm 101; during operation, when the positioning block 25 rotates inside the support arm 101, by providing balls 26 between the positioning block 25 and the support arm 101, the friction between the positioning block 25 and the support arm 101 can be reduced, thereby reducing wear between the positioning block 25 and the support arm 101 and increasing the service life of the device.

[0042] During operation, when the lens's focal length needs to be tested, the lens can be placed inside the placement slot. Then, the take-up roller 5 is rotated, causing it to pull the pull rope 6. The tightening of the pull rope 6 pulls the fixing block 3 into the placement slot, thus squeezing and fixing the lens. By rotating the take-up roller 5, multiple fixing blocks 3 can be pulled together, making lens fixing more convenient. At the same time, a lens holder slot can be opened on the side of the placement slot to place a lens holder with the lens to be tested, making the device more convenient to use. After the lens is placed inside the placement slot and fixed, the position of the fixing seat 2 can be adjusted by the adjustment component, so that the lens can be better focused with the testing mechanism of the machine base 1. The structural design of squeezing and fixing the lens inside the placement slot by the fixing block 3 enables the device to clamp and fix the edge of the lens, effectively solving the problem of easy scratching of the lens when using a pressure frame to support the lens. When the lens needs to be removed, the fixing block 3 can be reset sequentially by pulling the spring, making it convenient for the next test.

[0043] When focusing is required on the lens inside the placement slot, the threaded rod 9 can be rotated. The threads on the surface of the threaded rod 9 engage with the threads inside the threaded block 8, causing the fixed seat 2 to slide on the top of the operating table 103. This allows for longitudinal adjustment of the fixed seat 2. Simultaneously, the electric push rod can be controlled to slide the push block 104, allowing for lateral adjustment of the detection device 102. This, in turn, adjusts the position of the lens of the detection device 102. As a result, when focusing the lens, the operator's hands can be removed from contact with the lens, making lens focusing more convenient.

[0044] When the take-up roller 5 is rotated to tighten the pull rope 6, the locking rod 14 can be rotated to move the locking rod 14 and the threaded engagement of the threaded bracket 13 downwards, thereby squeezing and fixing the rotating handle at the top of the take-up roller 5. This effectively prevents the spring from pulling back the fixing block 3 after the take-up roller 5 is adjusted, thus preventing the take-up roller 5 from being pulled back and making the fixing block 3 fix the lens better.

[0045] When the lens needs to be inspected, the placement rack 20 can be pushed out first by the electric push cylinder, and then the lens can be placed inside the placement rack 20. After placement, the placement rack 20 can be pulled into the cleaning tank 15 by the electric push cylinder, and then the water pump can be started to fill the water pipe 18 with water. Then, the water can be sprayed downward through the spray nozzle 19 to clean the surface of the lens, making the surface of the lens cleaner. After the water passes through the placement rack 20, it will fall into the bottom of the cleaning tank 15 through the through hole, and then be drawn by the water pump and introduced into the water pipe 18 through the water inlet pipe 17, so that the water can be recycled. At the same time, the water outlet pipe 16 can be connected by a flange, so that the water outlet pipe 16 can be quickly disassembled, making it easier to replace dirty water.

[0046] When the fixing block 3 presses and fixes the lens, the fixing block 3 made of rubber can fix the lens, which can make the contact area between the fixing block 3 and the lens larger, thus making the fixing block 3 fix the lens better. At the same time, the soft fixing pad 21 contacts the lens, which can effectively prevent the hard fixing block 3 from damaging the lens.

[0047] When the pull rope 6 is tightened to push the fixed block 3, the anti-wear wheels 22 set at the corners of the fixed block 3 can change the sliding friction between the pull rope 6 and the fixed block 3 into rolling friction, so that the wear between the pull rope 6 and the fixed block 3 is less, thereby effectively avoiding excessive wear between the fixed block 3 and the pull rope 6, which could easily cause the pull rope 6 to break.

[0048] When the fixed block 3 slides inside the fixed seat 2, the fixed seat 2 restricts the positioning rod 23, which makes the fixed block 3 less likely to tilt during the sliding process, making the fixed block 3 more stable during the sliding process.

[0049] When water enters the interior of the water guide pipe 18 through the water inlet pipe 17, the blocking ball 24 makes the water flow more evenly inside the water guide pipe 18, thus making the amount of water sprayed from each spray nozzle 19 more uniform. At the same time, the blocking ball 24 makes the water spray range larger, thus making the water spray cleaning effect on the lens better.

[0050] As the threaded rod 9 rotates, the support arm 101 restricts the positioning block 25, making the threaded rod 9 more stable during rotation and improving the effect of the threaded rod 9 in pushing the threaded block 8.

[0051] When the positioning block 25 rotates inside the support arm 101, the ball bearing 26 between the positioning block 25 and the support arm 101 reduces the friction between them, thereby reducing wear and increasing the service life of the device.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
