Description

Technical Field

[0001] The invention belongs to the technical field of framing printers, and in particular relates to a framing printer that moves up and down to adjust an optical distance. Background Art

[0002] In order to reduce the time wasted on children copying questions to correct mistakes, a framing printer was invented;

[0003] But there are still some disadvantages of the current framing printer:

[0004] First, the framing is not flexible and it is easy to take pictures offset;

[0005] Secondly, you need a lot of auxiliary tools to take a picture of a complete question, or the question is beyond the light area and cannot be printed, and you need an adult to guide the shooting. Moreover, too many auxiliary tools will cause inconvenience in carrying. If an auxiliary tool is lost, you have to replace it, which requires additional financial expenses.

[0006] In view of this, we propose to move the light distance framing printer up and down to adjust it. Summary of the invention

[0007] The object of the present invention is to provide a framing printer capable of adjusting the optical distance by moving up and down, so as to solve the problems raised in the above-mentioned background technology.

[0008] In view of this, the present invention provides a framing printer capable of adjusting the optical distance by moving up and down, comprising a framing printer body, a groove being provided on one side of the framing printer body, and further comprising:

[0009] An adjustment frame, the adjustment frame is fixedly installed in the groove, and a collection groove and a first slide groove are opened on one side of the adjustment frame, and a second slide groove is opened on one side of the adjustment frame and on both sides of the first slide groove;

[0010] A rocker arm, wherein the rocker arm is arranged on one side of the first slide slot, and a shaft column is rotatably mounted on one end of the rocker arm, a main shaft on the shaft column passes through the first slide slot and a gear is rotatably mounted thereon, and two secondary shafts on the shaft column respectively pass through two second slide slots, and threaded holes are provided on the two secondary shafts on the shaft column, and screws are installed in the threads of the threaded holes;

[0011] A rack, the rack being fixedly mounted on the inner wall of the adjusting frame and meshing with the gear;

[0012] A movable groove, wherein the movable groove is provided at the bottom side of the rocker arm, and a stabilizing plate is slidably installed in the movable groove, a camera, a heat dissipation shell, a light emitter and a fixing block are fixedly installed at the bottom side of the stabilizing plate, two light-collecting shells are slidably installed in the heat dissipation shell, and the light emitter is located between the two light-collecting shells, a baffle is fixedly installed at the bottom end of the fixing block, and one end of the baffle passes through one of the light-collecting shells and is located at the bottom side of the light emitter, and a convex mirror is fixedly installed in the baffle;

[0013] A protective shell is arranged at the outlet of the movable groove.

[0014] In this technical solution, the overall structure of the viewfinder printer body is made into a swing arm that can be bent 90 degrees, and a camera and a light source are embedded inside the swing arm. A convex mirror is set under the light source, and a baffle is used to block light, so that light can be irradiated through the square convex mirror to form a square light source as shown in Figure 11;

[0015] After students unfold the rocker arm from the adjustment bracket, they can move the rocker arm so that the rocker arm drives the gear to move up and down on the rack through the shaft column to adjust the appropriate distance between the wrong question book and the camera. At the same time, students can also determine it according to the light area illuminated by the light source on the wrong question book. When students take the wrong question book, the light area will illuminate the largest area. If they need to shoot smaller questions, they only need to move the rocker arm toward the position of the wrong question book. At this time, the light area will become smaller as the distance changes. With such a simple operation, you can shoot the wrong questions you want. This solution perfectly avoids the two major problems of inaccurate shooting of the viewfinder printer body and shooting out of area. It is not only easy to operate, but also easier to carry.

[0016] In the above technical solution, the main shaft on the shaft column is slidably connected to the first slide groove, and the two secondary shafts on the shaft column are slidably connected to the two second slide grooves respectively.

[0017] In this technical solution, it is ensured that the main shaft on the shaft column can slide up and down in the first slide groove, and it is ensured that the two secondary shafts on the shaft column can slide up and down in the two second slide grooves respectively.

[0018] The above technical solution also includes:

[0019] A limit groove, the limit groove is provided on the viewfinder printer body and is located on one side of the groove, a slide plate is slidably installed in the limit groove, a blocking plate is provided at one end of the slide plate, and a slide groove three and a blocking groove are provided on the top side of the blocking plate;

[0020] A rotating shaft, wherein the rotating shaft is slidably mounted in the sliding groove three, and one end of the rotating shaft is fixed to the sliding plate;

[0021] A storage slot, which is arranged at the bottom of the framing printer body and is connected to the limit slot;

[0022] The scale line is fixedly mounted on the adjustment frame and is located on one side of one of the second slide slots.

[0023] In this technical solution, the baffle can be taken out from the storage slot and drive the slide plate to move downward in the limit slot. Then, the baffle is rotated 180° with the rotation axis as the axis. After the baffle is rotated 180°, the bottom of the baffle is placed against the desktop. At this time, the student can put the wrong answer book on the storage slot to stabilize the wrong answer book, ensuring that the student does not need to fix the wrong answer book with his hands, which is convenient for the student to use the viewfinder printer body to take pictures.

[0024] When students unfold the rocker arm from the adjustment frame, they can move the rocker arm to drive the gear to move up and down on the rack through the shaft column, and can adjust the appropriate distance between the wrong answer book and the camera according to the scale line to facilitate students' observation.

[0025] In the above technical solution, the rotating shaft and the slide plate are an integrally formed structure, the cross-sections of the rotating shaft and the slide groove three are both T-shaped structures, and the storage groove is engaged with the baffle.

[0026] In this technical solution, the structural stability of the rotating shaft and the sliding plate is ensured, and the rotating shaft is ensured not to fall off in the sliding groove three and can slide normally. After the shooting is completed, it is convenient to clip the baffle into the storage groove.

[0027] In the above technical solution, cylinders are fixedly installed on the top side of the stabilizing plate and near the four corners, and a fixing tube fixed to the inner wall of the movable groove is sleeved on the cylinder, and a spring is sleeved on the fixing tube.

[0028] In the technical solution, by setting the cylinder, the fixed tube and the spring 1, it is ensured that when the whole device vibrates, the spring 1 can always be pressed on the stabilizing plate. Even after the stabilizing plate moves in the movable groove, the stabilizing plate can return to its original position under the pressure of the spring 1, thereby ensuring the structural stability of the camera and the light-emitting body.

[0029] In the above technical solution, one end of the spring 1 is tightly welded to the inner wall of the movable groove, and the other end of the spring 1 is in contact with the stabilizing plate.

[0030] In this technical solution, the structural stability of spring one is ensured.

[0031] In the above technical solution, movable grooves are provided on the bottom side of the protective shell and near the four corners, a movable block is slidably installed in the movable groove, and one end of the movable block passes through the movable groove and extends into the rocker arm, and a plurality of springs are fixedly installed at the bottom of the movable block.

[0032] In this technical solution, when a person moves the moving block in the moving groove, the moving block can squeeze a number of springs to contract and move one end of the moving block out of the rocker arm. At this time, the protective shell can be taken out of the movable groove, making it convenient for the person to repair the damaged camera and light source.

[0033] In the above technical solution, the number of the plurality of springs 2 is at least two, a slot matching one end of the moving block is provided on the inner wall of the movable groove, and one end of the moving block is plugged and installed in the slot.

[0034] In this technical solution, it is ensured that the second spring can provide sufficient elastic force to the moving block, ensuring that one end of the moving block can be inserted into the slot, thereby enhancing the structural stability of the protective shell.

[0035] In the above technical solution, the protective shell is plugged into the storage slot, and the size of the storage slot is larger than the size of the protective shell.

[0036] In this technical solution, it is ensured that the protective shell can be stored in the storage slot.

[0037] In the above technical solution, the convex mirror has a square structure.

[0038] In this technical solution, it is ensured that the light is irradiated through the square convex mirror to form a square light source such as Fig.11 shown.

[0039] The beneficial effects of the present invention are:

[0040] The framing printer can be adjusted by moving up and down. The overall structure of the framing printer body is a swing arm that can be bent 90 degrees. A camera and a light source are embedded in the swing arm. A convex mirror is set under the light source, and a baffle is used to block the light. The light is irradiated through the square convex mirror to form a square light source, ensuring that students will not take photos offset.

[0041] After the students unfold the rocker arm from the adjustment frame, they can move the rocker arm so that the rocker arm drives the gear to move up and down on the rack through the shaft column, and can adjust the appropriate distance between the wrong question book and the camera according to the scale of the scale line. At the same time, students can also determine it according to the light area of ​​the light source shining on the wrong question book. When the students take the wrong question book, the light area will illuminate the largest area. If you need to shoot smaller questions, you only need to move the rocker arm to the position of the wrong question book. At this time, the light area will become smaller as the distance changes. Such a simple operation can take pictures of the wrong questions you want. This solution perfectly avoids the two major problems of inaccurate shooting of the framing printer body and shooting out of area. It is not only easy to operate, but also easier to carry. The overall device has flexible framing, and students can operate it by themselves, without more cumbersome operating techniques, and at the same time, no additional financial expenses are required.
