Description

Technical Field

[0001] The present invention relates to the technical field of psychological teaching auxiliary equipment, and specifically to a sand table teaching equipment for psychological teaching. Background Technique

[0002] Psychology, as a discipline that studies human psychological phenomena and the mental functions and behavioral activities influenced by them, has a very rich variety of teaching experimental equipment, and each has its own unique functions. These equipment play a crucial role in many fields such as psychological teaching, scientific research exploration, psychological counseling and treatment practice. Among many psychological teaching experimental equipment, the sand table teaching equipment has received extensive attention and application due to its unique charm and practical value. As a non-verbal expressive therapy tool, the sand table teaching equipment provides a free, safe, and protected space for the client, allowing them to freely place and shape with sand tools on the sand table, thereby intuitively showing their inner emotional world, interpersonal relationship patterns, and potential psychological conflicts. After the use of the sand table teaching equipment, teaching staff usually only collect the sand tools in the sand table, while the sand still remains in the sand table. If the sand is stored in the sand table for a long time, especially in a humid environment, it is easy to breed microorganisms such as bacteria and molds. These microorganisms will not only corrode the sand table materials and pose a threat to the health of users, such as causing skin allergies and respiratory diseases, but also the sand directly stored in the sand table is easy to mix with other substances in the sand table, such as dust and debris in the sand table, forming dirt that is difficult to clean, affecting the overall appearance of the sand table, increasing the difficulty and cost of sand table cleaning, and the sand stored in the sand table for a long time will deteriorate in quality due to moisture and caking, affecting the production effect during the sand table teaching process. For example, caked sand is difficult to shape and cannot present delicate and smooth lines and patterns.

[0013] Compared with the prior art, the present invention provides a sand table teaching device for psychology teaching, which has the following beneficial effects: 1. Through the provided sand automatic storage mechanism, after the sand table body is used, it can drive the bottom plates on both sides inside the sand table body to incline downward and form a gap therebetween, so that the sand inside the sand table body passes through the gap and flows into the sand storage box below. This not only can collect the sand into the sand storage box in time after use, avoiding the sand being exposed to the air for a long time, thus effectively reducing the breeding opportunities of bacteria and mold microorganisms and reducing the health risks caused by users contacting the contaminated sand, but also can avoid the sand being damp and caking after being stored in the sand table body for a long time, thereby helping to maintain the quality of the sand, ensuring that delicate and smooth lines and patterns can be presented during the sand table teaching process, improving the teaching effect, and through the centralized collection and storage of the sand inside the sand table body, it is convenient for teaching staff to clean the sand table body, making the sand table body easier to keep clean, reducing the difficulty and cost of cleaning, and at the same time improving the overall appearance of the sand table body; Among them, when a gap is formed between the bottom plates on both sides so that the sand flows along the gap into the sand storage box below, the sand table inside the sand table body can still be blocked inside the sand table body, avoiding the situation that teaching staff carry the sand out of the sand table body during the collection of the sand table. Teaching staff can not only collect the sand table more conveniently without worrying about the sand being carried out of the sand table body, saving the time for collecting the sand table and improving the teaching efficiency, and the sand will not be scattered or wasted due to the carrying of the sand table, thus keeping the teaching environment clean.

[0014] 2. Through the provided elastic telescopic columns and side plates, they can slide up and down in the grooves synchronously according to the changes of the bottom plate, thus always maintaining close contact with the bottom plate. This not only effectively prevents sand from leaking through the gaps when the bottom plate is tilted, ensures that the sand can smoothly flow into the sand storage box, and maintains the sealing between the sand storage box and the sand table body, but also the good sealing can prevent external moisture and water from entering the sand storage box, thereby keeping the sand dry and clean. This helps prevent the sand from getting damp and caking, extends its service life, and ensures the best usage effect during the sand table teaching process.

[0015] 3. Through the provided sand treatment mechanism, during the process of collecting the sand inside the sand table body into the lower sand storage box, it can synchronously drive the filter plate to reciprocate between the sand table body and the sand storage box to filter and clean the sand. This not only effectively removes impurities, dust, and debris in the sand, makes the sand purer, maintains the quality of the sand, and ensures the best usage effect during the sand table body teaching process, but also reduces the workload of subsequent additional cleaning of the sand and lowers the cleaning difficulty. Among them, through the provided connecting plate, during the process of driving the filter plate to reciprocate and filter the sand, it can synchronously drive the lifting plate to reciprocate up and down, drive the bottom plate to swing up and down reciprocally inside the sand table body, so that the sand tools can shake inside the sand table body, avoiding the situation where sand remains on the surface of the sand tools and blocks the gaps between the sand tools and the bottom plate. This can not only loosen and remove the sand in the gaps, keep the bottom of the sand table body unobstructed, facilitate the sand to smoothly flow from inside the sand table body into the lower sand storage box, but also maintain the cleanliness of the sand tools, extend their service life, and improve the subsequent usage effect.

[0016] 4. Through the provided first sector gear, second sector gear, and connecting shaft, during the reciprocating swing of the bottom plate, it can synchronously drive the knocking ball to knock on the bottom of the bottom plate. The knocking of the knocking ball on the bottom of the bottom plate will generate vibrations, which not only helps loosen the sand adhering to the bottom plate and makes it easier to flow into the lower sand storage box, thereby improving the fluidity of the sand and accelerating the speed of sand collection, but also the knocking vibration can prevent the sand from accumulating and blocking in the gaps between the bottom plate and the sand tools, reduce the residue of the sand inside the sand table body, and keep the sand table clean and orderly.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] A sand table teaching device for psychology teaching in this embodiment, as Figure 1 - Figure 8As shown, the sandbox teaching equipment includes a base 1 and a sandbox body 2, the sandbox body 2 is fixedly connected to the upper end surfaces on the front and rear sides of the base 1, and the upper end surfaces on the left and right sides of the base 1 are symmetrically provided with grooves 9, and a sand storage box 5 and a sand tool storage box 6 are slidably connected to the base 1, and the sand storage box 5 is located above the sand tool storage box 6, and both the sand storage box 5 and the sand tool storage box 6 can be pulled out from the base 1; a through groove 10 is provided on one side of the base 1, and a support frame 3 in an L-shape as a whole is fixedly connected to one side of the sandbox body 2, and a camera 4 is fixedly connected to the lower end surface of the horizontal part of the support frame 3, and the camera 4 is located at the center above the sandbox body 2. Through the provided camera 4, it is convenient for teaching staff to take pictures of the surface of the sandbox body 2 and transmit them to the display screen for teaching; the sandbox teaching equipment also includes an automatic sand storage mechanism 7 and a sand processing mechanism 8.

[0022] The automatic sand storage mechanism 7 is used to automatically store the sand in the sandbox body 2 into the sand storage box 5. Figure 2 As shown, the automatic sand storage mechanism 7 includes a lifting plate 703, two symmetrically arranged bottom plates 701 and two symmetrically arranged rotating shafts 704. The two bottom plates 701 are both arranged at the bottom of the sand table body 2, and the two rotating shafts 704 are respectively fixedly connected to the two bottom plates 701. The two rotating shafts 704 are both connected to the sand table body 2 for rotation. The lifting plate 703 is vertically slidably connected to the side wall on one side of the sand table body 2. When the rotating shaft 704 is rotated on the sand table body 2, the rotating shaft 704 can drive the bottom plate 701 to rotate downward inside the sand table body 2, driving the two bottom plates 701 to form a gap, so that the sand inside the sand table body 2 flows out from the inside of the sand table body 2 through the gap.

[0023] In this embodiment, Figure 2 and Figure 3 As shown, two connecting grooves 707 are symmetrically provided on the lifting plate 703, and linkage columns 708 are slidably connected in the two connecting grooves 707. Linkage plates 702 are fixedly connected to the two linkage columns 708. One end of the two linkage plates 702 away from the linkage columns 708 is fixedly connected to two rotating shafts 704 respectively. When the lifting plate 703 moves up and down, the linkage columns 708 move in the connecting grooves 707, and the linkage columns 708 drive the linkage plates 702 to rotate. When the linkage plates 702 rotate, the rotating shafts 704 are driven to rotate.

[0024] In this embodiment, Figure 4 and Figure 5As shown, a side plate 705 is provided below each bottom plate 701. The two side plates 705 are respectively connected to the two grooves 9 in a vertical sliding manner. Two elastic telescopic columns 706 are symmetrically and fixedly connected to the lower end surface of each side plate 705. The plurality of elastic telescopic columns 706 are respectively fixedly connected to the inner bottom of the two grooves 9. When the bottom plate 701 rotates downward, the bottom plate 701 pushes the side plate 705 to move downward, causing the side plate 705 to slide into the groove 9. At this time, the side plate 705 will squeeze the elastic telescopic column 706. When the bottom plate 701 rotates back to the horizontal state, the thrust received by the side plate 705 disappears. At this time, through the rebounding force of the elastic telescopic column 706, the side plate 705 can be automatically ejected from the groove 9.

[0025] In the prior art, if sand is stored in the sand table for a long time, especially in a humid environment, it is easy to breed microorganisms such as bacteria and molds. These microorganisms will not only corrode the sand table materials and pose a threat to the health of users, such as causing skin allergies and respiratory diseases, but also the sand directly stored in the sand table is easy to mix with other substances in the sand table, such as dust and debris, to form dirt that is difficult to clean, affecting the overall appearance of the sand table, increasing the difficulty and cost of cleaning the sand table, and the sand stored in the sand table for a long time will deteriorate in quality due to moisture and caking, affecting the production effect during the sand table teaching process. For example, caked sand is difficult to shape and cannot present delicate and smooth lines and patterns. Compared with the prior art, in the present application, after the sand table body 2 is used, the bottom plates 701 on both sides inside the sand table body 2 can be driven to tilt downward, and a gap is formed between the two bottom plates 701, so that the sand inside the sand table body 2 can flow through the gap into the lower sand storage box 5. This not only can timely collect the used sand into the sand storage box 5, avoiding the sand being exposed to the air for a long time, thereby effectively reducing the breeding opportunity of bacteria and mold microorganisms and reducing the health risk caused by users contacting the contaminated sand, but also can avoid the situation of moisture and caking of the sand stored in the sand table body 2 for a long time, thereby helping to maintain the quality of the sand, ensuring that the sand can present delicate and smooth lines and patterns during the sand table teaching process, improving the teaching effect, and through the centralized collection and storage of the sand inside the sand table body 2, it is convenient for teaching staff to clean the sand table body 2, making the sand table body 2 easier to keep clean, reducing the difficulty and cost of cleaning, and at the same time improving the overall appearance of the sand table body 2.

[0026] In addition, during the process of sand flowing into the lower sand storage box 5 along the gap between the two bottom plates 701, the sand tools inside the sand table body 2 can still be blocked inside the sand table body 2, avoiding the situation where teaching staff carry sand out of the sand table body 2 during the collection of sand tools. The teaching staff can collect the sand tools more conveniently and put the sand tools into the sand tool storage box 6 without worrying about the sand being carried out of the sand table body 2, saving the time for collecting sand tools, improving the teaching efficiency, and preventing the sand from being scattered or wasted due to the carrying of sand tools, thus keeping the teaching environment clean and tidy.

[0027] This embodiment also provides a sand treatment mechanism 8 for filtering and cleaning sand, as Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 8 shown. The sand treatment mechanism 8 includes a filter plate 803. The filter plate 803 is horizontally slidably connected to the base 1. The filter plate 803 is disposed between the sand table body 2 and the sand storage box 5. One side of the filter plate 803 is fixedly connected with a connecting block 812. The connecting block 812 is slidably connected to the inside of the through groove 10. When the connecting block 812 is moved left and right, the connecting block 812 drives the filter plate 803 to move left and right.

[0028] In this embodiment, as Figure 1 , Figure 6 and Figure 7 shown, the upper end surface of the connecting block 812 is fixedly connected with a frame 811. One side above the frame 811 is rotatably connected with a connecting plate 807. One end of the connecting plate 807 is rotatably connected to the center of the lower end surface of the lifting plate 703. When the frame 811 moves horizontally back and forth, the frame 811 pulls the lower end of the connecting plate 807 to move. The connecting plate 807 will reciprocally change between a vertical state and an inclined state. While the connecting plate 807 changes its state, it will pull the lifting plate 703 rotatably connected to its upper end to move up and down.

[0029] In this embodiment, as Figure 7As shown in the figure, a cylinder 810 is slidably connected inside a frame 811. One end of the cylinder 810 is fixedly connected to a dial 809. The end of the dial 809 away from the cylinder 810 is fixedly connected to a drive shaft 808. On one side of the base 1 close to the drive shaft 808, a mounting bracket 801 is fixedly connected. A drive motor 802 is fixedly connected to the mounting bracket 801. The drive shaft 808 is fixedly connected to the output end of the drive motor 802. When the drive motor 802 is turned on to drive the drive shaft 808 to rotate, the drive shaft 808 will drive the cylinder 810 to move synchronously around the drive shaft 808 through the dial 809. During this process, the cylinder 810 slides inside the frame 811, and at the same time, the cylinder 810 drives the frame 811 to move left and right, and the frame 811 drives the connecting block 812 to move left and right inside the through groove 10.

[0030] In this embodiment, as Figure 6 and Figure 8 shown, the sand treatment mechanism 8 further includes two symmetrically arranged connecting shafts 804. The two connecting shafts 804 are respectively arranged below the two rotating shafts 704. Both ends of the two connecting shafts 804 are rotatably connected to support blocks 806. A plurality of support blocks 806 are fixedly connected to the lower end surface of the sand table body 2. Equally spaced knocking balls 805 are fixedly connected to the outer surfaces of the two connecting shafts 804. A plurality of knocking balls 805 are all located below the sand table body 2. When the connecting shaft 804 rotates between the support blocks 806 to drive the knocking balls 805 to move towards the bottom plate 1, it can drive the knocking balls 805 to gradually approach the bottom plate 701 and knock on the lower end surface of the bottom plate 701.

[0031] In this embodiment, as Figure 8 shown, one end of each of the two connecting shafts 804 is fixedly connected to a first sector gear 813. Above the two first sector gears 813, a second sector gear 814 is meshed. The two second sector gears 814 are respectively fixedly connected to the outer surfaces of the two rotating shafts 704. When the rotating shaft 704 rotates, through the meshing connection of the first sector gear 813 and the second sector gear 814, the connecting shaft 804 can be driven to rotate.

[0032] Compared with the prior art, in the process of collecting the sand inside the sand table body 2 into the lower sand storage box 5, the present application can synchronously drive the filter plate 803 to move left and right reciprocally between the sand table body 2 and the sand storage box 5 to filter and clean the sand, not only effectively removing impurities, dust and debris in the sand, making the sand purer, maintaining the quality of the sand, ensuring the best use effect during the teaching process of the sand table body 2, but also reducing the workload of subsequent additional cleaning of the sand and lowering the cleaning difficulty.

[0033] In addition, through the arranged connecting plate 807, during the process of driving the filter plate 803 to reciprocate for filtering sand, the lifting plate 703 can be synchronously driven to reciprocate up and down, driving the bottom plate 701 to swing reciprocally up and down inside the sand table body 2, so that the sand tools can vibrate inside the sand table body 2, avoiding the situation that sand remains on the surface of the sand tools and the sand tools block the gap between the two bottom plates 701. This can not only loosen and remove the sand in the gap between the two bottom plates 701, facilitating the smooth flow of sand from inside the sand table body 2 into the lower sand storage box 5, but also keep the cleanliness of the sand tools, extend their service life, and improve the subsequent use effect.

[0034] It should be noted that the sand tools in this application document are made of resin material and are not easily damaged.

[0035] The working process and principle involved in the overall content of the above embodiments are as follows: After the teaching staff finishes teaching with the sand table body 2, the driving motor 802 is turned on to drive the driving shaft 808 connected to its output end to rotate. Since one end of the driving shaft 808 is connected with a dial plate 809, a cylinder 810 is installed on one side of the dial plate 809, and the cylinder 810 is slidably connected within the frame 811. Therefore, during the rotation of the driving shaft 808, the cylinder 810 can be driven by the dial plate 809 to slide within the frame 811, and the frame 811 can be toggled to move left and right by the cylinder 810. While the frame 811 is moving left and right, the connecting block 812 below it will reciprocally slide within the through slot 10. During the horizontal movement of the frame 811, the frame 811 will pull the lower end of the connecting plate 807 rotatably connected above it to move, causing the connecting plate 807 to reciprocally switch between a vertical state and an inclined state. When the connecting plate 807 moves from the vertical state to the inclined state, the connecting plate 807 will pull the lifting plate 703 to slide downward on the side wall of the sand table body 2. As the lifting plate 703 descends, the height of the communication slots 707 opened on both sides of the lifting plate 703 will uniformly change. At this time, the linkage columns 708 within the communication slots 707 will be pushed. While the linkage columns 708 horizontally move within the communication slots 707, they will simultaneously move downward synchronously with the lifting plate 703. While descending, the linkage columns 708 will toggle the rotating shaft 704 to rotate through the linkage plate 702. The rotating shaft 704 drives the bottom plate 701 to move downward, creating a gap between the two bottom plates 701. At this time, the sand inside the sand table body 2 will be affected by the downward inclination of the bottom plate 701, slide on the surface of the bottom plate 701, flow towards the gap formed between the two bottom plates 701, and fall into the sand storage box 5 below through the gap. This not only can timely collect the sand into the sand storage box 5 after use, avoiding the sand being exposed to the air for a long time, thus effectively reducing the breeding opportunities of bacteria and mold microorganisms and reducing the health risks caused by users contacting the contaminated sand, but also can avoid the situation that the sand gets damp and caked after being stored in the sand table body 2 for a long time, thereby helping to maintain the quality of the sand, ensuring that delicate and smooth lines and patterns can be presented during the sand table teaching process, improving the teaching effect. Moreover, by centrally collecting and storing the sand inside the sand table body 2, it is convenient for the teaching staff to clean the sand table body 2, making the sand table body 2 easier to keep clean, reducing the difficulty and cost of cleaning, and at the same time enhancing the overall appearance of the sand table body 2; Among them, when the connecting plate 807 rotatably connected between the lifting plate 703 and the frame 811 changes from an inclined state to a vertical state, the lifting plate 703 will rise on the side wall of the sand table body 2, and through the communication groove 707, the linkage column 708, the linkage plate 702 and the rotating shaft 704, the bottom plate 701 is toggled to rotate upward again. Since the frame 811 moves horizontally back and forth, the state of the connecting plate 807 changes reciprocally, pulling the lifting plate 703 to reciprocally rise and fall on the side wall of the sand table body 2. Therefore, the bottom plate 701 inside the sand table body 2 will reciprocally swing up and down during the sand discharging process, enabling the sand tools to shake inside the sand table body 2, avoiding the situation that sand remains on the surface of the sand tools and blocking the gaps between the bottom plate 701. This not only can loosen and remove the sand in the gaps, keep the bottom of the sand table body 2 unobstructed, facilitate the sand to smoothly flow from the inside of the sand table body 2 into the lower sand storage box 5, but also can maintain the cleanliness of the sand tools, extend their service life, and improve the subsequent use effect; During the process of sand flowing through the gap formed between the two bottom plates 701 into the lower sand storage box 5, affected by the size of the gap, the sand tools placed inside the sand table body 2 will not fall into the sand storage box 5 together with the sand, and can still block the sand tools inside the sand table body 2, avoiding the situation that teaching staff carry sand out of the sand table body 2 during the collection of sand tools. The teaching staff can not only collect the sand tools more conveniently, without worrying about the sand being carried out of the sand table body 2, saving the time for collecting sand tools and improving the teaching efficiency, but also the sand will not be scattered or wasted due to the carrying of the sand tools, thus keeping the teaching environment clean; During the reciprocating swing of the bottom plate 701, as the bottom plate 701 moves downward, the bottom plate 701 will push the side plate 705 in contact with it below into the groove 9 opened on the upper end surface of the base 1, and push the side plate 705 to squeeze the elastic telescopic column 706 connected to the inner bottom of the groove 9. It should be noted that the elastic telescopic column 706 will contract when being squeezed and can automatically rebound when the pressure disappears. When the bottom plate 701 moves upward, through the rebounding force of the elastic telescopic column 706, the side plate 705 can be automatically pushed out of the groove 9, so that the upper end surface of the side plate 705 and the lower end surface of the bottom plate 701 are always in close contact. This not only effectively prevents the sand from leaking from the gap when the bottom plate 701 is inclined, ensures that the sand can smoothly flow into the sand storage box 5, and maintains the sealing between the sand storage box 5 and the sand table body 2, but also the good sealing can prevent external moisture and water from entering the sand storage box 5, thereby keeping the sand dry and clean. This helps to prevent the sand from getting damp and caking, extends its service life, and ensures the best use effect during the sand table teaching process; During the process of the frame 811 driving the connecting block 812 to move horizontally back and forth in the through groove 10, since the connecting block 812 is connected to the filter plate 803, the connecting block 812 can drive the filter plate 803 to move horizontally back and forth synchronously. At this time, before the sand inside the sand table body 2 flows into the sand storage box 5, it will first fall above the filter plate 803. After being filtered by the filter plate 803, the sand is cleaned, effectively removing impurities, dust and debris in the sand, making the sand more pure, maintaining the quality of the sand, ensuring the best use effect during the teaching process of the sand table body 2, and reducing the workload of subsequent additional cleaning of the sand and the cleaning difficulty; While the rotating shaft 704 rotates to drive the bottom plate 701 to swing up and down reciprocally, the rotating shaft 704 drives the second sector gear 814 to rotate. The second sector gear 814 drives the first sector gear 813 meshed with it to rotate. The first sector gear 813 drives the connecting shaft 804 and the rotating shaft 704 to rotate reciprocally. For example, when the rotating shaft 704 drives the bottom plate 701 to rotate downward, the connecting shaft 804 will be driven to rotate in the opposite direction through the first sector gear 813 and the second sector gear 814. At this time, the distance between the knocking ball 805 connected to the outer surface of the connecting shaft 804 and the bottom plate 701 will gradually shorten until it knocks on the lower end surface of the bottom plate 701. The knocking of the knocking ball 805 on the bottom of the bottom plate 701 will generate vibration, which not only helps to loosen the sand adhering to the bottom plate 701, making it easier to flow into the lower sand storage box 5, thereby improving the fluidity of the sand and accelerating the speed of sand collection, but also the knocking vibration can prevent the sand from accumulating and blocking in the gap between the bottom plate 701 and the sand tools, reducing the residue of the sand inside the sand table body 2 and keeping the sand table clean and orderly; When the teaching staff needs to maintain the filter plate 803, they only need to manually slide the side plates 705 on both sides of the base 1 downward into the groove 9, and then they can directly maintain and clean the filter plate 803. When the side plates 705 are separated from the bottom plate 701, the bottom plate 701 is limited by the rotating shaft 704, the linkage plate 702, the linkage column 708 and the lifting plate 703 and will not rotate downward.
