Description

Technical Field

[0001] This utility model relates to the field of eyeglass nose pad spacing detection technology, specifically an eyeglass nose pad spacing detection device. Background Technology

[0002] The nose pad is a component of the eyeglass frame that supports the bridge of the nose. In other words, the component that supports the bridge of the nose and keeps the eyeglass frame in a constant position in front of the eyes is called the nose pad. The nose pad is the supporting structure of the eyeglass frame on the bridge of the nose.

[0003] Currently, the common method for testing the distance between nose pads on glasses involves a worker holding the glasses with one hand and using a measuring ruler with the other. This method inevitably causes the worker's hand to shake during testing, which may lead to test failure. In addition, this testing method is relatively cumbersome. Therefore, it is necessary to optimize the nose pad distance testing device through technological innovation and design. Utility Model Content

[0004] Currently, the common method for measuring the distance between nose pads on eyeglasses involves a worker holding the glasses with one hand and using a measuring ruler with the other. This method is prone to hand wobbling, potentially leading to measurement failure, and is also cumbersome. To address these issues, this application provides a device for measuring the distance between nose pads on eyeglasses. By pulling an upward-moving block, the block, guided by a guide post, moves a movable plate. The movable plate and a baffle compress a spring, causing the movable plate to move a rectangular plate and a rubber block upwards. At this point, the temples are placed inside the rectangular groove, ensuring the nose pads are positioned on either side of the two L-shaped plates. Releasing the pulling block allows the movable plate, under the spring's action, to clamp the temples with the rectangular groove, preventing the glasses from wobbling. Simultaneously, twisting a rotating post rotates a bidirectional lead screw, which moves two movable blocks in opposite directions. These blocks move the L-shaped plates and a pointer. When the L-shaped plate contacts the nose pad, the pointer's reading is recorded, completing the measurement of the nose pad distance. The measurement process is simple and convenient.

[0005] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0006] A device for detecting the distance between nose pads on eyeglasses includes:

[0007] The base plate has support frames on both sides of its top, a fixing plate is fixed between the two support frames, and a rectangular plate is provided on each of the two support frames.

[0008] Two fixed blocks are located on both sides of the top of the base plate, and two movable blocks are provided between the two fixed blocks;

[0009] Elastic mechanism; the elastic mechanism is located on top of the fixed plate and is used to apply elastic force to the rectangular plate;

[0010] A moving mechanism, located between two fixed blocks, is used to drive the moving blocks to move.

[0011] In one possible implementation, the elastic mechanism includes a movable plate on top of a fixed plate, a baffle on top of the movable plate, a fixed post fixed to the top of the fixed plate, the fixed post passing through the movable plate and fixedly connected to the top plate, a spring sleeved outside the fixed post between the baffle and the movable plate, a guide post fixed to the top of the movable plate, the guide post passing through the baffle, a pulling block fixed to the top of the guide post, a rectangular slot on the top of the support frame, a rectangular plate fixedly connected to the bottom of the movable plate, the rectangular plate being able to enter the rectangular slot, rubber blocks fixed on both sides of the bottom of the rectangular plate, the pulling block driving the movable plate to move via the guide post, the movable plate and the baffle compressing the spring, the movable plate driving the rectangular plate and rubber blocks to move upward, at which point the temples of the glasses can be placed inside the rectangular slot, the pulling block released, the movable plate, under the action of the spring, will drive the rectangular plate and rubber blocks to cooperate with the rectangular slot to clamp the temples of the glasses, preventing the glasses from shaking.

[0012] In one possible implementation, the moving mechanism includes a bidirectional lead screw disposed between two fixed blocks. One end of the bidirectional lead screw is rotatably connected to one of the fixed blocks, and a rotating column passes through the other fixed block. The rotating column is fixedly connected to the other end of the bidirectional lead screw and can rotate on the fixed block. The two moving blocks are respectively located on the positive and negative threads of the bidirectional lead screw, and the moving blocks are threadedly connected to the bidirectional lead screw. The rotating column drives the bidirectional lead screw to rotate, and the bidirectional lead screw drives the two moving blocks to move in opposite directions.

[0013] In one possible implementation, an L-shaped plate is fixed to the top of each of the two movable blocks, so that the L-shaped plate can move between the nose pads. The movable blocks are slidably connected to the base plate through a groove. A pointer is fixed to the side of each of the two movable blocks away from the fixed plate. A scale is provided on the top of the base plate. The pointer and the scale facilitate the measurement of distance. The movable blocks can drive the L-shaped plate and the pointer to move.

[0014] In summary, this utility model has at least one of the following beneficial technical effects:

[0015] 1. By pulling the pull block upwards, the pull block can drive the moving plate to move via the guide post. The moving plate and the baffle will compress the spring, and the moving plate will drive the rectangular plate and the rubber block to move upwards. At this time, the temples of the glasses can be placed inside the rectangular groove, while ensuring that the nose pads are located on both sides of the two L-shaped plates. Then, release the pull block. Under the action of the spring, the moving plate will drive the rectangular plate and the rubber block to clamp the temples of the glasses in conjunction with the rectangular groove, preventing the glasses from shaking.

[0016] 2. By twisting the rotating column, the rotating column drives the double-acting screw to rotate. The double-acting screw drives the two moving blocks to move in opposite directions. The moving blocks can drive the L-shaped plate and the pointer to move. When the L-shaped plate contacts the nose pad, the scale indicated by the pointer is recorded to complete the measurement of the nose pad distance. The measurement process is relatively simple and convenient. Attached Figure Description

Detailed Implementation

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The instrument placement rack involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] This embodiment describes the specific structure of a device for detecting the distance between nose pads on eyeglasses, as detailed in the following reference. Figures 1-3 As shown, a device for detecting the distance between nose pads on eyeglasses includes:

[0023] The base plate 7 has support frames 6 on both sides of the top of the base plate 7. A fixing plate 18 is fixed between the two support frames 6. A rectangular plate 14 is provided on both support frames 6.

[0024] Two fixed blocks 1 are located on both sides of the top of the base plate 7, and two movable blocks 12 are provided between the two fixed blocks 1;

[0025] Elastic mechanism; the elastic mechanism is located on the top of the fixed plate 18 and is used to apply elastic force to the rectangular plate 14;

[0026] The moving mechanism is located between two fixed blocks 1 and is used to move the moving block 12.

[0027] Before measuring the distance between the nose pads of the glasses, the glasses need to be clamped and fixed. The elastic mechanism includes a movable plate 5 on the top of the fixed plate 18, a baffle 3 on the top of the movable plate 5, a fixed post 17 fixed on the top of the fixed plate 18, the fixed post 17 passing through the movable plate 5 and fixedly connected to the top plate, a spring 16 sleeved on the outside of the fixed post 17 between the baffle 3 and the movable plate 5, a guide post 15 fixed on the top of the movable plate 5, the guide post 15 passing through the baffle 3, a pulling block 4 fixed on the top of the guide post 15, a rectangular groove 2 on the top of the support frame 6, and a rectangular plate 14. The rectangular plate 14 is fixedly connected to the bottom of the movable plate 5 and can enter the rectangular groove 2. Rubber blocks 13 are fixed on both sides of the bottom of the rectangular plate 14. The pulling block 4 can drive the movable plate 5 to move upward through the guide post 15. The movable plate 5 and the baffle 3 will squeeze the spring 16. The movable plate 5 will drive the rectangular plate 14 and the rubber blocks 13 to move upward. At this time, the temples of the glasses can be placed inside the rectangular groove 2. Release the pulling block 4. Under the action of the spring 16, the movable plate 5 will drive the rectangular plate 14 and the rubber blocks 13 to cooperate with the rectangular groove 2 to clamp the temples of the glasses and prevent the glasses from shaking.

[0028] When it is necessary to measure the distance between the nose pads of eyeglasses, the moving mechanism includes a bidirectional lead screw 10 disposed between two fixed blocks 1. One end of the bidirectional lead screw 10 is rotatably connected to one of the fixed blocks 1, and a rotating column 19 passes through the other fixed block 1. The rotating column 19 is fixedly connected to the other end of the bidirectional lead screw 10 and can rotate on the fixed block 1. Two moving blocks 12 are respectively located on the positive and negative threads of the bidirectional lead screw 10. The moving blocks 12 are threadedly connected to the bidirectional lead screw 10. The rotating column 19 drives the bidirectional lead screw 10 to rotate, and the bidirectional lead screw 10 drives the two moving blocks 12 to move in opposite directions.

[0029] Meanwhile, L-shaped plates 9 are fixed to the top of both movable blocks 12, so that the L-shaped plates 9 can move between the nose pads. The movable blocks 12 and the base plate 7 are slidably connected by a sliding groove. A pointer 11 is fixed to the side of both movable blocks 12 away from the fixed plate 18. A scale 8 is provided on the top of the base plate 7. The pointer 11 and the scale 8 are convenient for measuring distance. The movable blocks 12 can drive the L-shaped plates 9 and the pointer 11 to move.

[0030] When measuring the nose pad distance, the operator first pulls the pull block 4 upwards. The pull block 4, through the guide post 15, moves the moving plate 5 upwards. The moving plate 5 and the baffle 3 compress the spring 16. The moving plate 5 moves the rectangular plate 14 and the rubber block 13 upwards. At this time, the temples can be placed inside the rectangular groove 2, while ensuring that the nose pads are located on both sides of the two L-shaped plates 9. Then, the pull block 4 is released. Under the action of the spring 16, the moving plate 5 moves the rectangular plate 14 and the rubber block 13 to clamp the temples in the rectangular groove 2. Then, the rotating post 19 is twisted. The rotating post 19 drives the bidirectional lead screw 10 to rotate. The bidirectional lead screw 10 drives the two moving blocks 12 to move in opposite directions. The moving blocks 12 can move the L-shaped plates 9 and the pointer 11. When the L-shaped plates 9 contact the nose pads, the mark 8 pointed to by the pointer 11 is recorded to complete the measurement of the nose pad distance.

[0031] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
