Description

Technical Field

[0001] The utility model belongs to the technical field of teaching aids, and particularly relates to a portable sandbox training teaching aid. Background Art

[0002] In order to enable students to grasp knowledge more intuitively and deeply during teaching, a sand table is needed to explain some applications. Moreover, the sand table used in teaching is not a real plate containing sand, but a plate fixed in a board or frame, which is used to teach some operations and management.

[0003] At present, the Chinese utility model with the publication number of CN212724464U discloses a multifunctional sand table combination teaching aid for warehousing and distribution, which relates to the field of sand table technology. The multifunctional sand table combination teaching aid for warehousing and distribution includes a sand table body, the four corners of the bottom of the sand table body are fixedly connected with supporting vertical plates, a square groove is provided on the top surface of the sand table body, and a limit protection component is provided on the top of the square groove. The limit protection component includes a movable horizontal plate, a limit card block and a movable cross bar. The number of the movable horizontal plate and the limit card block is set to two, and strip horizontal grooves are provided at both ends of the square groove. The movable horizontal plate is fixedly connected with movable cylinders on both sides near one end of the supporting vertical plate. The multifunctional sand table combination teaching aid for warehousing and distribution avoids the problem that the sand table teaching aid lacks certain protection, and the sand table is easily covered with a lot of dust and difficult to clean during long-term storage, which brings great trouble to the user, reduces the inconvenience of the user in cleaning the sand table, and improves the practicality of the sand table combination teaching aid.

[0004] In order to prevent the teaching aids on the top of the sandbox from accumulating dust when not in use, the existing sandbox practical training teaching aids generally use a glass cover to cover the sandbox. This also results in a certain space height between the sandbox blocks and the glass cover, which must be opened manually when in use. Otherwise, it is difficult to point to the exact block position from the top of the glass cover during teaching, which is easy to cause misunderstandings, and is therefore inconvenient for practical use. At the same time, the existing sandbox practical training teaching aids are not convenient for quickly carrying and replacing the teaching aid blocks on the sandbox according to teaching needs, so it is difficult to adapt to different teaching needs, has low portability, and cannot meet usage requirements. Utility Model Content

[0005] The purpose of the utility model is to provide a portable sandbox training teaching aid, which has the advantages of being able to carry and replace the teaching aid plate on the top of the sandbox according to teaching needs, improving portability and allowing the sandbox training teaching aid to be quickly stored to prevent dust accumulation, thereby facilitating practical use.

[0006] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a portable sandbox training teaching aid, including a support frame, the top of the support frame is fixedly connected to a fixed platform, one side of the fixed platform is fixedly connected to a fixed cylinder, one side of the inside of the fixed cylinder is fixedly installed with a motor, the output end of the motor is fixedly connected to a winding wheel rotatably connected to the fixed cylinder, both sides of the inside of the fixed platform are slidably connected with sliders, a connecting plate is fixedly connected between the two sliders, a dust shielding curtain is fixedly connected to the side of the connecting plate close to the winding wheel, the end of the dust shielding curtain away from the connecting plate is fixedly wrapped with the surface of the winding wheel, and the side of the slider away from the dust shielding curtain is fixedly connected to a spring fixedly connected to the fixed platform.

[0007] The above technical solution is adopted, by opening the cylinder to retract the sand table training teaching aid into the inside of the fixed platform when it is not in use. Then the dust-shielding curtain is unfolded and covered on the top of the sand table training teaching aid to block the top of the sand table training teaching aid, and the dust-shielding curtain can also be automatically retracted. This can not only prevent dust from accumulating on the top of the sand table training teaching aid, but also facilitate the use of the sand table training teaching aid; by twisting the threaded rod to engage with the thread of the sand table main body, and using the conical block to push the trapezoidal slider to slide outward and fit the teaching aid block, the teaching aid block is fixed to the top of the sand table main body by friction. This makes it easy to carry the teaching aid block on the sand table training teaching aid, meet the use requirements of different teaching, and improve the portability of the sand table training teaching aid.

[0008] The utility model is further configured as follows: a cylinder is fixedly installed inside the fixed platform, and a sandbox main body slidably connected to the fixed platform is arranged at the output end of the cylinder.

[0009] By adopting the above technical solution, the air cylinder is opened to drive the sand table body to slide up and down inside the fixed platform, thereby retracting the sand table body into the inside of the fixed platform.

[0010] The utility model is further configured as follows: a teaching aid block is arranged inside the sandbox body, a threaded rod threadedly connected to the sandbox body is slidably penetrated inside the teaching aid block, trapezoidal sliders slidably connected to the sandbox body are arranged on both sides of the threaded rod, and a conical stop block slidably connected to the trapezoidal slider is rotatably connected to the bottom of the threaded rod.

[0011] The adoption of the above technical solution makes it easy to carry the teaching aid sections on the sandbox training teaching aids, meet the use requirements of different teaching, and improve the portability of the sandbox training teaching aids.

[0012] The utility model is further configured as follows: the output end of the cylinder is fixedly connected with an arc-shaped joint which is slidably connected with the sandbox body, and arc-shaped magnetic plates which are magnetically attracted to each other are fixedly installed between the arc-shaped joint and the sandbox body.

[0013] By adopting the above technical solution, the sand table body can be pressed to rotate on the surface of the arc joint, driving the teaching aids block on the top to adjust the angle, and the position of the sand table body can be fixed by the mutual magnetic adsorption of the arc magnetic plates, thereby facilitating horizontal viewing teaching and improving the viewing range.

[0014] The utility model is further configured as follows: the four sides of the sandbox body, left and right sides, and front and back sides are all arc-shaped.

[0015] By adopting the above technical solution, the sandbox body will not be restricted by the inside of the fixed platform during the process of rotating the angle inside the fixed platform, thereby reducing the sliding friction.

[0016] The utility model is further configured as follows: a side of the exterior of the fixing cylinder close to the motor is opened and a heat dissipation net is fixedly installed thereon.

[0017] The adoption of the above technical solution facilitates ventilation and heat dissipation of the motor and improves working stability.

[0018] The utility model is further configured as follows: a knob is fixedly connected to the top of the threaded rod, and an anti-slip pattern is provided on the surface of the knob.

[0019] The above technical solution is adopted to improve the surface friction, making it easier to turn the knob to drive the threaded rod to rotate.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. When the sandbox training aid is not in use, open the cylinder to retract it into the fixed platform. Then unfold the dust-shielding curtain and cover it on the top of the sandbox training aid to block the top of the sandbox training aid. At the same time, the dust-shielding curtain can be automatically retracted. This can not only prevent dust from accumulating on the top of the sandbox training aid, but also facilitate the use of the sandbox training aid.

[0022] 2. By twisting the threaded rod to engage with the thread of the sand table body, and using the conical block to push the trapezoidal slider to slide outward and fit the teaching aid block, the teaching aid block is fixed on the top of the sand table body through friction. This makes it easier to carry the teaching aid block on the sand table training teaching aid, meet the use requirements of different teaching, and improve the portability of the sand table training teaching aid.
