Description

Technical Field

[0001] The invention relates to the technical field of educational telegraph machines, in particular to a telegraph machine for educational experiments. Background Art

[0002] Nowadays, children's education has become particularly important. Toys are a good helper to guide children's intellectual development. Building block toys can effectively improve children's hands-on ability and thinking ability, and effectively improve children's learning potential and creativity.

[0003] Among them, the educational telegraph composed of wood chips needs to be assembled before use. However, the toys currently available on the market are generally assembled by simple socketing and clamping. During the splicing process, there will be wood splinters on the edges of the wood chips. If the wood chips are not polished before installation, the children may be stabbed by the splinters during installation. Therefore, the wood chips need to be polished before installation. The existing polishing method is generally that the user holds the wood chip in one hand and the sandpaper in the other hand, and polishes by friction between the sandpaper and the edge of the wood chip. However, this polishing method still has the problem of the user being stabbed by the splinters during the polishing process, because the hand needs to contact the wood chip and hold the wood chip steady during the polishing process, otherwise the wood chip may slide during the polishing process. When the child polishes by himself, the difficulty of polishing is further increased due to the small strength. If the parents or teachers polish the wood chips in advance, the children may lack the participation of this step, which reduces the interactivity of the entire operation. Therefore, the present application provides a telegraph for educational experiments to meet the needs. Summary of the invention

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, by setting up an auxiliary installation mechanism and a limiting fixing component, not only can the first clamp and the second clamp arranged opposite to each other be used to squeeze and fix the single-piece model before the device is combined and used, but the single-piece model can be fixed by using the structure so that the hand does not directly contact the single-piece model, and then the child is allowed to hold the sandpaper body so that the sandpaper body is wrapped and located at the edge of the single-piece model, and then the child pinches one side of the sandpaper body so that the side of the sandpaper body used for grinding and the edge of the single-piece model are repeatedly rubbed to quickly remove the wood thorns on the edge of the guide part, effectively preventing the problem of accidentally scratching the hand when grinding the single-piece model. The device also effectively increases the interactivity between the child and the parents, teachers or other friends when the device is used, and by using the limiting fixing component, the auxiliary installation mechanism is more stable in the first use state, the structure of the device is simple, easy to use and operate, and the practicability of the device is good, which is convenient for promotion and use.

[0016] By providing the first clip and the second clip in the auxiliary installation mechanism, not only can the first clip and the second clip be used flexibly in two use states by utilizing the arc structure of both the first clip and the second clip, but also in the first use state, the first clip and the second clip are in arc structures arranged opposite to each other, so that the first clip and the second clip use the limiting fixing component to make the ends of the first clip and the second clip fixedly connected to the bottom of the second base, at this time, the first clip and the second clip are close to each other and produce a squeezing tendency, the single-piece model is placed between the first clip and the second clip, and the user cooperates to force the first base and the second base closer, so that the squeezing tendency of the first clip and the second clip is further strengthened, so that the single-piece model is more stably fixed between the first clip and the second clip for grinding and use, when the first clip and the second clip are used in combination, the device has good stability in the first use state and is convenient and quick to use, and in the second use state, the password paper can be quickly installed on the frame supported by the first clip and the second clip, so that it is convenient for children to observe the password paper when using the device. The Morse code content on the upper part, the coordinated use of the structures further makes the practicality of the first clip and the second clip better, and the second lightweight groove opened on the first clip and the fourth lightweight groove opened on the second clip can not only reduce the production costs of the two, but also make the deformation effect of the first clip and the second clip better. The coordinated use of the structures effectively makes the use effect of the auxiliary installation mechanism better. The extrusion deformation of the anti-slip sheet makes the clamping and fixing effect of the first clip and the second clip on the single-piece model more firm, and the outer wall of the anti-slip sheet is rough, and the anti-slip sheet is made of rubber material. The setting of the first weakened part makes it easier for the second clip to be placed more stably at the bottom of the first clip in the second use state, and the use of the first weakened part, the second weakened part, the third weakened part and the fourth weakened part makes it easier for the first clip and the second clip to deform from these points, so that the first clip and the second clip can be quickly switched between the two states. The coordinated use of the structures further makes the use effect of the auxiliary installation mechanism and the limiting fixing component better, and the structure is simple and easy to use.

[0017] By providing the first limiting plate and the second limiting plate in the auxiliary installation mechanism, when the user brings the first base and the second base close to each other, the user can better apply force to the first base and the second base, thereby achieving a better squeezing effect of the first clamp and the second clamp, so that the single-piece model is tightly fixed between the two without displacement. The single-piece model can be fixed by utilizing the structure so that the hand does not directly contact the single-piece model, and the first limiting groove provided on the second limiting plate makes it easy to place the bottom of the password paper in the first limiting groove in the second use state, so that the password paper can be more stably placed on the device for use, thereby making it easy for children to view the password information when simulating typing the Morse code. The coordinated use of the structures effectively makes the use effect of the auxiliary installation mechanism better, and the structure is simple and easy to use.

[0018] By providing a limiting buckle and a second limiting block in the limiting fixing assembly, the limiting buckle and the second limiting block can be used to quickly fix the ends of the first clip and the second clip together, so that the first clip and the second clip can be used for grinding the single-piece model in the first use state, and the setting of the guide part can make the second limiting block more quickly inserted and fixed into the limiting buckle when inserted into the limiting buckle by the guidance of the guide part, so that the ends of the first clip and the second clip can be quickly connected and fixed together, and the limiting part is used to squeeze the second limiting block stuck in the limiting buckle. The pressure limit makes the connection between the limit buckle and the second limit block more stable, and at the same time, the hollow cavity opened in the second limit block can produce good deformation when the second limit block is squeezed, so that the second limit block can be more quickly clamped in the limit buckle, and the rebound force of the hollow cavity can be used to make the outer wall of the second limit block tightly press the inner wall of the limit buckle, and the limit buckle and the second limit block are used to limit and fix the ends of the first clip and the second clip. The coordinated use of the structures effectively makes the use effect of the limit fixing component better, and the structure is simple and easy to use.

[0019] By providing a third limit block and a clamping block in the limit fixing assembly, the third limit block and the clamping block can be used to further limit and fix the ends of the first clip and the second clip, so that the restorative elastic force of the first clip and the second clip causes the two to squeeze each other, so that the single-piece model can be more stably fixed between the two. After polishing all the individual single-piece models, and using the setting of the second limit groove and the fourth limit block, the connection between the third limit block and the clamping block is tighter, so that the first clip and the second clip can be more stably placed on the edge of the second base for use in the first use state. The coordinated use of the structures effectively makes the use effect of the limit fixing assembly better, and the structure is simple and easy to use.

[0020] In summary, the device can not only realize the grinding work of the single-piece model quickly and easily installed through the coordinated use of the auxiliary installation mechanism and the limiting extrusion mechanism and the various components therein, but also effectively enhance the interaction between people during the grinding process, thereby effectively increasing the fun of the device, and by utilizing the structural design, the auxiliary installation mechanism and the limiting extrusion mechanism and the various components therein can be quickly converted between two states, so that when the device is installed and used, it is convenient to fix the password paper on the device, so that it is convenient for children to observe the contents on the password paper and quickly tap the corresponding Morse code, and the device has a simple structure, is convenient and quick to use, and has a low production cost, good practicality, and is easy to promote and use.

In the first use state, the bottoms of the first base 8 and the second base 15 are not connected, the first clip 11 and the second clip 19 are in arc-shaped structures arranged opposite to each other, and the ends of the first clip 11 and the second clip 19 are fixedly connected by a limiting assembly, the card slot 14 is clamped and fixed in the limiting buckle 23, and the third limiting block 28 is located at the end of the card block 29, and the third limiting block 28 is fixedly connected to the card block 29, so that the first clip 11 and the second clip 19 are fixedly connected to the bottom of the second base 15 by the limiting fixing assembly; in the second use state, the second clip 19 is located at the bottom of the first clip 11, and the two are pressed and fitted against each other, and the bottoms of the first base 8 and the second base 15 are fixedly connected by a limiting extrusion mechanism, and at this time, the card block 29 is clamped in the card slot 14; The device uses an auxiliary installation mechanism and a limit fixing assembly so that before the device is used in combination, the first clamping piece 11 and the second clamping piece 19 arranged opposite to each other can be used to squeeze and fix the single-piece model 36. At this time, the hands of the parent or teacher are respectively placed on the first limit plate 9 and the second limit plate 17, and the first limit plate 9 and the second limit plate 17 are pushed to make the first clamping piece 11 and the second clamping piece 19 approach each other, so that the single-piece model 36 is tightly fixed therebetween without displacement, and the structure is used to fix the single-piece model 36 without direct contact between the hand and the single-piece model 36, and then the child is allowed to hold the sandpaper body 37, so that the sandpaper body 37 is wrapped and located at the edge of the single-piece model 36, and then the child pinches the sandpaper body 37 with his hand.

In addition, by using the setting of the anti-slip sheet 21, the single-piece model 36 is placed between the first clip 11 and the second clip 19 and contacts the anti-slip sheet 21.

The present structure can increase the supporting force of the first clip 11 and the second clip 19 by setting the reinforcing strip 22, so that the first clip 11 and the second clip 19 will not be excessively bent and broken, and the setting of the guide portion 26 makes it possible for the second limiting block 24 to be inserted into the limiting buckle 23 more quickly by guiding the guide portion 26, so that the first clip 11 and the second clip 19 The ends are quickly connected and fixed together, and the limiting portion 27 is used to squeeze and limit the second limiting block 24 clamped in the limiting buckle 23, so that the limiting buckle 23 and the second limiting block 24 are more stably connected to each other, and at the same time, the hollow cavity 25 opened in the second limiting block 24 is used to make the second limiting block 24 produce good deformation when squeezed, so that the second limiting block 24 can be clamped in the limiting buckle 23 more quickly, and the resilience of the hollow cavity 25 is used to make the outer wall of the second limiting block 24 tightly press the inner wall of the limiting buckle 23, and the second limiting groove 31 and the fourth limiting block 30 are set to make the connection between the third limiting block 28 and the clamping block 29 tighter, so that the first clip 11 and the second clip 19 are more stably placed on the edge of the second base 15 in the first use state, and the structure is simple, and the coordinated use of the structures further makes the use effect of the auxiliary installation mechanism and the limiting and fixing assembly better.

[0034] The working principle of the technical solution provided by the present invention is as follows: When in use, first align the first base 8 and the second base 15 and place them on a horizontal work surface. At this time, let the hands of the parent or teacher be respectively placed on the first limit plate 9 and the second limit plate 17, and push the first limit plate 9 and the second limit plate 17 to make the first clamp 11 and the second clamp 19 approach each other, so that the single-piece model 36 is tightly fixed therebetween without displacement, and the structure is used to prevent the hand from directly contacting the single-piece model 36, so that the single-piece model 36 can be fixed, and then let the child hold the sandpaper body 37, so that the sandpaper body 37 is wrapped and located at the edge of the single-piece model 36, and then the child pinches one side of the sandpaper body 37 with his hand, so that the side of the sandpaper body 37 used for grinding and the edge of the single-piece model 36 Repeated friction can quickly remove the wood thorns on the edge of the guide part 26. The structure is simple, which effectively prevents the problem of accidentally scratching the hands when polishing the single-piece model 36. The coordinated use of the structures also effectively increases the interactivity between children and parents, teachers or other friends when the device is used. The use of the limit fixing component makes the auxiliary installation mechanism more stable in the first use state. The limit buckle 23 and the second limit block 24 are used to limit and fix the ends of the first clip 11 and the second clip 19, and the third limit block 28 and the clamping block 29 are used to further limit and fix the ends of the first clip 11 and the second clip 19, so that the restorative force of the first clip 11 and the second clip 19 makes the two mutually The first and second clamps 11 and 19 are pressed and squeezed, so that the single-piece model 36 can be fixed more stably between the two. After grinding all the single single-piece models 36, the third limit block 28 is separated from the card block 29, and the limit buckle 23 is separated from the card slot 14. Then, the first clip 11 and the second clip 19 are rebounded to the top. The first clip 11 and the second clip 19 are naturally stretched upward and approach a hook shape in a natural state without being acted upon by external forces. The second clip 19 is placed at the bottom of the first clip 11, so that the first clip 11 limits the second clip 19, and the second limit block 24 and the first weakened portion 32 are used to further limit the second clip 19. At the same time, the card block 29 at the bottom of the second base 15 is set in the card slot 14 opened on the first base 8, so that the second clamp 19 is The first base 8 and the second base 15 are in a relatively static and stable state, and then the top of the password paper 38 is fixed in the limit buckle 23, and the bottom of the password paper 38 is placed on the side of the second limit plate 17, so that the password paper 38 is stably placed on the device for use, which can facilitate children to watch the password content on the password paper 38 when simulating the Morse code, thereby making it more convenient for the device to simulate the sending and receiving operation, and when simulating the sending and receiving of messages, the receiver model body 1 and the transmitter model body 5 are combined into one body by using an auxiliary installation mechanism, so that the side of the receiver model body 1 close to the buzzer body 3 is opposite to the transmitter model body 5, so that the receiver model body 1 and the transmitter model body 5 can be used by one person to send messages and watch the receiving situation.At the same time, the side of the receiver model body 1 close to the buzzer body 3 can be placed with the back of the transmitter model body 5, so that one person can operate the transmitter model body 5 to send a message, and the other person can watch the display light 4 on the receiver model body 1 and listen to the buzzer body 3 receiving the signal received by the receiver. The coordinated use of the structure effectively enhances the diversity of the use of the device, making the use of the device more convenient, and further increases the interactivity of the device. The auxiliary installation mechanism and the limit fixing mechanism can also facilitate the storage of the receiver model body 1 and the transmitter model body 5. The device has good practicality and low production cost. The integrated structure makes the connection between the structures tighter, and the stability is better during use. The first base is used The first lightweight groove 10 opened on the first base 8 can effectively reduce the production cost of the first base 8, and at the same time reduce the mass of the first base 8, which is convenient for carrying and using the first base 8. Similarly, the third lightweight groove 16 opened on the second base 15 can reduce the production material of the third lightweight groove 16 and reduce the mass of the third lightweight groove 16. The second lightweight groove 12 opened on the first clip 11 and the fourth lightweight groove 20 opened on the second clip 19 can not only reduce the production cost of both, but also make the deformation effect of the first clip 11 and the second clip 19 better. The first limiting groove 18 opened on the second limiting plate 17 is convenient for placing the bottom of the password paper 38 in the first limiting groove 18 in the second use state, so that the password paper 38 can be placed in the first limiting groove 18. The paper 38 is placed on the device more stably for use, so that the child can easily see the password information when simulating the Morse code. The anti-slip sheet 21 is set so that when the single-piece model 36 is placed between the first clamping piece 11 and the second clamping piece 19, the two clamping pieces are in contact with the anti-slip sheet 21. The extrusion deformation of the anti-slip sheet 21 makes the clamping and fixing effect of the first clamping piece 11 and the second clamping piece 19 on the single-piece model 36 more firm. The outer wall of the anti-slip sheet 21 is rough, and the anti-slip sheet 21 is made of rubber material. The first weakened portion 32 is set so that the second clamping piece 19 can be placed more stably at the bottom of the first clamping piece 11 in the second use state. The first weakened portion 32, the second weakened portion 33, the third weakened portion 34 and the fourth weakened portion 35 are used. The use of makes it easier for the first clip 11 and the second clip 19 to deform from these points, so that the first clip 11 and the second clip 19 can be quickly switched between two states. The coordinated use of the structures further makes the use of the auxiliary installation mechanism and the limit fixing assembly better. The reinforcement strip 22 can be provided to increase the support strength of the first clip 11 and the second clip 19, so that the first clip 11 and the second clip 19 will not be excessively bent and broken. The guide portion 26 can be used to allow the second limit block 24 to be inserted into the limit buckle 23 more quickly, thereby allowing the ends of the first clip 11 and the second clip 19 to be quickly connected and fixed together.The limiting part 27 is used to squeeze and limit the second limiting block 24 stuck in the limiting buckle 23, so that the stability of the connection between the limiting buckle 23 and the second limiting block 24 is better. At the same time, the hollow cavity 25 opened in the second limiting block 24 can produce good deformation when the second limiting block 24 is squeezed, so that the second limiting block 24 can be stuck in the limiting buckle 23 more quickly, and the rebound force of the hollow cavity 25 is used to make the outer wall of the second limiting block 24 tightly press the inner wall of the limiting buckle 23. The second limiting groove 31 and the fourth limiting block 30 are set to make the connection between the third limiting block 28 and the card block 29 tighter. The design of the device restores the working principle of the real telegraph and receiver, so that children can understand the internal structure and working principle of the telegraph well when assembling and using the device, so as to more deeply appreciate the charm of Morse code. The structure of the device is simple, and its production cost is low. The device has good practicality and educational effect, and is easy to teach and use.
