Description

Technical Field

[0001] This invention relates to the field of English teaching devices, specifically to a situational English teaching and training device. Background Technology

[0002] With increasingly frequent global exchanges, the cultivation of practical application skills in English, as an international language, is becoming more and more important. Situational English teaching has become one of the mainstream teaching models because it can simulate real language use scenarios and improve learners' language application abilities.

[0003] A spoken English training mouth shape trainer, disclosed in Publication No. CN221960637U, offers the following benefits: It allows learners to hold a mobile phone or tablet and compare their mouth shapes using a mirror. On the one hand, current situational English teaching requires learners to carry their own mobile phones, phone stands, and pronunciation training tools, which is not only burdensome and inconvenient to store, but also results in the lack of a stable structure for the phone, making it prone to shifting when playing situational dialogues. On the other hand, traditional training lacks precise pronunciation references, making it difficult for learners to intuitively judge whether their lip shapes and mouth movements are standard, and hindering real-time correction of pronunciation deviations based on the situational content, leading to low training efficiency and poor results. Therefore, it is necessary to propose a situational English teaching training device. Summary of the Invention

[0004] To address the problems in the prior art, the present invention provides a situational English teaching and training device.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a situational English teaching and training device, including a base frame arranged in a U-shape and a top frame hinged to the base frame, wherein a mirror body is embedded in the upper part of the top frame; The top frame has a transmission cavity at its inner end. Limiting grooves are formed at both ends of the top frame laterally and longitudinally in the middle. A transmission gear is rotatably connected within the transmission cavity. The transmission gear is horizontally engaged with short L-shaped rack rods at both its upper and lower ends. One end of each short rack rod is fixedly connected to an L-shaped transverse slide rod. The transmission gear is longitudinally engaged with a long L-shaped rack rod. One end of the long rack rod is fixedly connected to a longitudinal slide rod. A longitudinal clamping plate is fixedly connected to the top of the vertical wall of each transverse slide rod. A transverse support plate is fixedly connected to the top of the vertical wall of each longitudinal slide rod. A telescopic rod is fixedly connected between the longitudinal slide rod and the limiting groove. A second spring is fixedly connected between the longitudinal slide rod and the limiting groove. The upper part of the base frame is provided with a bottom groove, and fixed blocks are fixedly connected to both sides of the bottom groove. A guide rod is fixedly connected between the fixed block and the bottom groove. A sliding rod is slidably connected to the wall of the guide rod. A first spring is fixedly connected between the sliding rod and the bottom groove. A stop plate is fixedly connected to the top of the sliding rod. The mirror body of the imitation mirror is provided with a lip-shaped reference mark, and the mirror body of the imitation mirror is provided with several ring-shaped reference marks of different sizes expanding outward from the lip-shaped reference mark as the center.

[0006] Specifically, a support member is rotatably connected to the middle of the bottom end of the base frame, and several abutment grooves are opened at both edges of the bottom end of the top frame. The inner diameter of the several abutment grooves matches the outer diameter of the support end of the support member, and the base frame and the top frame are interference-fitted together.

[0007] Specifically, the top of the mirror body is fixedly connected to a mounting component that engages with the top of the top frame. A pull strap is provided in the middle of the outer wall of the mounting component. A limit rod is fixedly connected to the bottom of the mirror body. A retaining ball is fixedly connected to the top of both ends of the limit rod.

[0008] Specifically, the top of the top frame has grooves on both sides of the mirror body with a diameter matching the limiting rod, and the top of each groove has a groove for interference fit with the ball.

[0009] Specifically, the long rack bar is located at the lower end of the two short rack bars.

[0010] Specifically, rubber gaskets are fixedly connected to the inner walls of the transverse support plate and the longitudinal clamping plate, as well as the side wall of the abutment plate.

[0011] Specifically, a connecting hole is provided through the upper end of the top frame, and the diameter and thickness of the connecting hole are greater than the diameter and thickness of the bottom plate.

[0012] One of the beneficial effects of this invention is that this device can automatically and stably fix the mobile phone, and is suitable for both portable and desktop use, improving the convenience of scenario training. When the mobile phone is placed on the horizontal support plate, its gravity can drive the vertical slide bar downwards. Through the meshing transmission of the long rack and pinion, the transmission gear and the short rack and pinion drive the vertical clamping plate to retract inwards and clamp the mobile phone. The rubber pad also prevents the mobile phone from slipping and scratching, facilitating the playback of scenario dialogue videos. When carrying, after folding the top and bottom frames, press the abutment plate. The abutment plate passes through the docking hole and pushes against the horizontal support plate. Using the same transmission principle, the entire device is tightened and clamped, preventing component wobbling and solving the problem of traditional tools requiring a separate mobile phone holder and being inconvenient to store.

[0013] The second beneficial effect of this invention is that the device can enhance the pronunciation correction effect and the prop fixation ability, thus optimizing the training experience. The lip shape reference imprint of the mirror body allows learners to calibrate the standard mouth shape in advance, and the ring-shaped reference imprint can intuitively show the dynamic changes of the mouth, helping to correct pronunciation deviations in real time by combining mobile phone content, thus solving the problem of lack of pronunciation reference in traditional training.

[0017] 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.

[0018] like Figures 1-7 As shown, the present invention provides the following technical solution: Example 1: A situational English teaching and training device includes a U-shaped base frame 1 and a top frame 2 hinged to the base frame 1. A mirror body 3 is embedded in the upper part of the top frame 2. A support member 10 is rotatably connected to the middle of the bottom end of the base frame 1. Several grooves 201 are opened at both edges of the bottom end of the top frame 2. The inner diameter of the grooves 201 matches the outer diameter of the support end of the support member 10. The base frame 1 and the top frame 2 are interlocked.

[0019] Among them, the base frame 1 support member 10, the top frame 2 abutment groove 201 and the interference snap structure: the support member 10 can rotate around the inner bottom end of the base frame 1, and its outer diameter of the support end matches the inner diameter of the abutment groove 201. After snapping, it can fix the unfolding angle of the top frame 2 and the base frame 1; the interference snap between the base frame 1 and the top frame 2 can achieve a tight closure when folded, to prevent the parts from loosening when carried, and to take into account both the stability and portability of use.

[0020] When using it, if you need to unfold it on the desktop, first release the interference fit between the base frame 1 and the top frame 2. Then, rotate the top frame 2 according to the training needs, so that it rotates around the hinge point with the base frame 1 to a suitable angle (rotate to close to 90° when using it for desktop sitting training).

[0021] After adjustment, rotate the support member 10 in the middle of the bottom of the base frame 1 and insert the support end of the support member 10 into the groove 201 at the corresponding edge of the bottom of the top frame 2 (because the inner diameter of the groove 201 matches the outer diameter of the support end of the support member 10, the angle can be fixed stably). Then place the base frame 1 on the table. The learner can conduct situational dialogue training facing the imitation mirror body 3 in the top frame 2 and observe the mouth shape and body movements through the mirror.

[0022] If you need to store and carry it, rotate the support 10 in the opposite direction to disengage it from the groove 201, and rotate and fold the top frame 2 until it fits snugly against the bottom frame 1. At this time, the bottom frame 1 and the top frame 2 are fixed by interference fit to form a compact whole, which is easy to put into a backpack or carry by hand without taking up too much space.

[0023] Example 2: The technical solution of this example, which differs from Example 1, includes: a transmission cavity 203 is provided at the inner end of the top frame 2; limit grooves 204 are provided transversely at both ends and longitudinally in the middle of the top frame 2; a transmission gear 20 is rotatably connected in the transmission cavity 203; short rack rods 21 in an L-shape are meshed with both the upper and lower ends of the transmission gear 20 transversely; one end of each short rack rod 21 is fixedly connected to a transverse slide rod 210 in an L-shape; and a long rack rod 22 in an L-shape is meshed with the transmission gear 20 longitudinally; one end of the long rack rod 22... A longitudinal slide rod 220 is fixedly connected. A longitudinal clamping plate 211 is fixedly connected to the top of the vertical wall of the transverse slide rod 210. A transverse support plate 221 is fixedly connected to the top of the vertical wall of the longitudinal slide rod 220. A telescopic rod 222 is fixedly connected between the longitudinal slide rod 220 and the limiting groove 204. A second spring 223 is fixedly connected between the longitudinal slide rod 220 and the limiting groove 204. A long rack rod 22 is located at the lower end of the two short rack rods 21. Rubber gaskets are fixedly connected to the inner walls of the transverse support plate 221 and the longitudinal clamping plate 211, as well as the side wall of the abutment plate 14.

[0024] Among them, the positional relationship between the long rack rod 22 and the short rack rod 21 is as follows: the long rack rod 22 is located at the lower end of the two short rack rods 21. It can convert the longitudinal movement of the longitudinal slide rod 220 into the lateral movement of the short rack rod 21 through meshing with the transmission gear 20, thereby driving the lateral slide rod 210 to link with the longitudinal clamping plate 211, so as to achieve stable clamping of the mobile phone or folded device. Rubber pad structure on the inner wall of the transverse support plate 221, the longitudinal clamping plate 211, and the side wall of the abutment plate 14: The rubber pad can increase the friction with the mobile phone and training props, preventing slippage during clamping; at the same time, it buffers the clamping force, preventing hard parts from scratching the mobile phone shell or prop surface, playing a protective role and extending the service life of the equipment and props; The structure of the top frame 2 docking hole 202: the diameter and thickness of the docking hole 202 are greater than the diameter and thickness of the bottom plate 14, so that the bottom plate 14 can pass through smoothly.

[0025] When in use, if used on a table: place the phone on the horizontal support plate 221 inside the top bracket 2. The phone's own weight will press down on the horizontal support plate 221, causing the vertical slide bar 220 to slide down along the limiting groove 204. At this time, the telescopic rod 222 retracts, and the second spring 223 is compressed and stores force.

[0026] During the downward movement of the longitudinal slide bar 220, the long rack bar 22 connected to it moves downward synchronously. Because the long rack bar 22 meshes longitudinally with the transmission gear 20 in the transmission cavity 203, and the long rack bar 22 is located at the lower end of the two short rack bars 21, it drives the transmission gear 20 to rotate. When the transmission gear 20 rotates, it meshes with the short rack bars 21 at the upper and lower ends of the transverse direction, causing the two short rack bars 21 to move synchronously towards the inside of the top frame 2, thereby pushing the transverse slide bar 210 to retract inward along the limiting groove 204, so that the longitudinal clamping plate 211 at the top of the transverse slide bar 210 moves closer to and clamps the sides of the mobile phone.

[0027] For carrying and use: Fold the top frame 2 and the base frame 1 together. At this time, the abutment plate 14 inside the base frame 1 will be exposed along the bottom groove 101 to the upper end of the base frame 1. Press the abutment plate 14 so that it passes through the docking hole 202 of the top frame 2 and pushes the transverse support plate 221 upward - this process is the same as the transmission principle mentioned above: after the transverse support plate 221 is subjected to force, it drives the longitudinal slide bar 220 to move along the limiting groove 204, causing the long rack rod 22 to drive the transmission gear 20 to rotate. Through the meshing action, it drives the short rack rod 21 and the transverse slide bar 210 to retract inward, and finally makes the longitudinal clamping plate 211 and the transverse support plate 221 cooperate with each other to tighten and clamp the top frame 2 and the base frame 1 in the closed state, making it convenient for carrying and use.

[0028] Example 3: The technical solution of this example, which differs from Example 1, includes: a lip-shaped reference mark 32 is provided on the mirror surface of the mirror body 3; several annular reference marks 33 of different sizes are provided on the mirror surface of the mirror body 3, expanding outward from the lip-shaped reference mark 32; a bottom groove 101 is provided through the upper end of the base frame 1; fixing blocks 11 are fixedly connected to both sides of the bottom groove 101; a guide rod 12 is fixedly connected between the fixing block 11 and the bottom groove 101; sliding rods 13 are slidably connected to the walls of the guide rod 12; a first spring 130 is fixedly connected to the sliding rod 13 and the bottom groove 101; and the top of the sliding rod 13 is fixedly... A fixed abutment plate 14 is connected to the top of the mirror body 3. A mounting piece 31 that engages with the top of the top frame 2 is fixedly connected to the top of the mirror body 3. A pull strap is provided in the middle of the outer wall of the mounting piece 31. A limit rod 34 is fixedly connected to the bottom of the mirror body 3. A retaining ball 35 is fixedly connected to the top of both ends of the limit rod 34. The top of the top frame 2 is provided with a sliding groove 301 on both sides of the mirror body 3 with a diameter matching the limit rod 34. A retaining groove 302 that is interference fit with the retaining ball 35 is provided at the top of the sliding groove 301. A docking hole 202 is provided through the upper part of the top frame 2. The diameter and thickness of the docking hole 202 are greater than the diameter and thickness of the abutment plate 14.

[0029] The structure of the imitation mirror body 3 includes the mounting component 31, the pull strap, the limiting rod 34, and the locking ball 35: the mounting component 31 achieves the initial locking between the imitation mirror body 3 and the top of the top frame 2; the pull strap facilitates the pulling, disassembly, and replacement of the imitation mirror body 3; the limiting rod 34 provides installation guidance for the imitation mirror body 3; and the locking ball 35, in conjunction with the locking groove 302, achieves secondary fixation, ensuring stable assembly of the imitation mirror body 3 and preventing displacement during training. The top frame 2 has a sliding groove 301 and a slot 302 structure: the diameter of the sliding groove 301 matches the limit rod 34, providing a precise sliding path for the limit rod 34 and ensuring the alignment and installation of the mirror body 3; the slot 302 is interference-fitted with the ball 35, which can firmly hold the limit rod 34, preventing the mirror body 3 from falling off due to collision or shaking during use, and enhancing the installation stability.

[0030] When in use, use it on a table: If you need to open the mirror body 3, first pull the strap on the outer wall of the mounting part 31, align the limiting rod 34 at the bottom of the mirror body 3 with the slide groove 301 at the top of the top frame 2, and push the limiting rod 34 to slide along the slide groove 301 until the locking balls 35 at both ends of the limiting rod 34 slide into the locking groove 302 at the top of the slide groove 301 - because the locking balls 35 and the locking groove 302 are interference fit, the mirror body 3 is stably fixed.

[0031] Before training begins, learners can first refer to the lip shape reference marks 32 on the mirror surface of the imitation mirror body 3 to adjust their own lip shape to align with the standard lip shape. This helps them master the correct mouth shape for basic pronunciations such as "a," "o," and "e," or easily mispronounced syllables such as "th" and "sh," laying a foundation for standard pronunciation in subsequent situational training. During training (such as playing situational dialogue videos or recording readings on a mobile phone), learners can visually observe the dynamic changes in the opening and closing range of their mouth and the position of their lips through several ring-shaped reference marks 33 of varying sizes centered on the lip shape reference marks 32 on the mirror surface. For example, when pronouncing the short "i" sound in "big," the mouth should be close to the inner ring-shaped reference mark 33; when pronouncing the long "a" sound in "large," the mouth needs to open to the outer ring-shaped reference mark 33. By referring to the ring-shaped reference marks 33, learners can quickly identify deviations between their own mouth movements and the standard pronunciation, and correct them in real time using the teaching content on their mobile phones to improve pronunciation accuracy.
