Description

Technical Field

[0001] This utility model belongs to the field of psychological sandplay technology, and in particular relates to a portable multi-level pull-out psychological sandplay. Background Technology

[0002] Sandplay therapy is a psychotherapy and counseling technique that uses sand trays, sand figures, and other materials. It is widely used in the field of psychological counseling and therapy. By "expressing the mind through images," sandplay therapy provides people with a way to explore their inner selves and integrate themselves. It is one of the most creative and inspiring techniques in psychotherapy.

[0003] Most sandplay therapy systems have several drawbacks. For example, only a single sandplay tray can be carried at a time. Carrying multiple trays requires repeated transport, wasting time. Furthermore, when changing the sand, simply emptying the tray can scatter sand into the air, deteriorating the room environment and requiring cleaning. Therefore, we propose a portable, multi-tiered pull-out sandplay therapy system. Utility Model Content

[0004] The purpose of this invention is to provide a portable, multi-level pull-out psychological sandplay to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a portable multi-level pull-out psychological sandplay, including a shell and several psychological sandplay trays, and further including: A drive groove is formed inside the housing. Several fixing blocks are inserted and installed in the drive groove. The fixing blocks are fixedly connected to several psychological sand trays. Limiting plates are slidably installed in the drive groove and on one side of the fixing blocks. One side of the limiting plates extends into the fixing blocks and is inserted and engaged with the fixing blocks. A plurality of discharge ports are provided, each of which is located within a plurality of psychological sand trays. Each of the plurality of psychological sand trays is provided with a power chamber. Each of the plurality of power chambers is rotatably equipped with a rotating bar. The plurality of discharge ports are connected to the plurality of power chambers. The plurality of rotating bars are located at the bottom of the plurality of discharge ports. A driving assembly, located within the housing, is used to drive a plurality of limiting plates to slide. A plurality of power components are located within a plurality of psychological sand trays and are used to drive a plurality of rotating bars to rotate.

[0006] In this technical solution, when several psychological sand trays need to be extracted for use, the set drive sub-component can drive several limiting plates to slide. After the several limiting plates are separated from several fixed blocks, the psychological sand trays can be pulled out of the housing. After the several psychological sand trays are used, they are all inserted into the housing, and then the several fixed blocks are all inserted into the drive slots. The set drive sub-component can fix the position of the several fixed blocks, and finally fix the position of the several psychological sand trays. Users can carry several psychological sand trays to a designated location. The number of trays carried at one time is large, avoiding repeated handling and wasting time. When the sand in the sand tray needs to be replaced, the power unit can rotate and reset the rotating bar. After the rotating bar rotates 90°, the sand in the sand tray can be discharged from the shell through the discharge port. At the same time, the operator can shake the sand tray to accelerate the sand falling downwards. Compared with manually rotating the sand tray and pouring out the sand, the sand will not scatter into the air, making it easier to remove the sand from the sand tray. The power unit can rotate and reset the rotating bar. After the rotating bar rotates 90° and resets, the discharge port can be blocked. Finally, the sand can be poured back into the sand tray. The operation is simple and the sand will not scatter when replacing it.

[0007] In the above technical solution, the driving component further includes: A sliding plate is slidably installed in a drive groove. The sliding plate has a plurality of sliding grooves, and a sliding column is slidably installed in each of the plurality of sliding grooves. The plurality of sliding columns are respectively fixedly connected to a plurality of limiting plates. A plurality of fixed posts are fixedly installed in the drive groove. The upper ends of the plurality of fixed posts penetrate the sliding plate and are slidably connected to the sliding plate. A first spring is sleeved on each of the plurality of fixed posts. The plurality of limiting plates are slidably connected to the drive groove.

[0008] In this technical solution, when several psychological sand trays need to be removed for use, the sliding plate is first pulled upwards, and at the same time, several first springs are compressed and contracted. The sliding plate drives several sliding columns to slide through several sliding grooves, and the sliding columns drive several limiting plates to slide. After the limiting plates are detached from the fixing blocks, the psychological sand trays can be pulled out of the housing. After the psychological sand trays are used, they are inserted back into the housing, and then the fixing blocks are inserted into the drive grooves. Through the above reverse operation, the positions of the fixing blocks can be fixed, and finally the positions of the psychological sand trays can be fixed. Users can carry several psychological sand trays to a designated location, carrying a large number at a time, avoiding repeated transportation and wasting time.

[0009] In the above technical solution, the power component further includes: A sliding bar is slidably installed inside the power chamber. A guide groove is provided inside the sliding bar, and a guide post is slidably installed inside the guide groove. A connecting rod is fixedly installed at the bottom end of the guide post, and the connecting rod is fixedly connected to the rotating bar. A limiting groove is formed inside the psychological sand tray and located on one side of the sliding bar. A guide rod is fixedly installed inside the limiting groove. A limiting post is slidably installed on the guide rod. A second spring is sleeved on the guide rod. One end of the limiting post passes through the limiting groove and extends into the sliding bar. The other end of the limiting post is inserted into the sliding bar. The limiting post and the limiting groove are slidably connected. The connecting rod is rotatably connected to the power cavity.

[0010] In this technical solution, when it is necessary to replace the sand in the psychological sand tray, firstly, pull the limiting post. At the same time, the second spring is compressed and contracted. After one end of the limiting post disengages from the sliding strip, the sliding strip can be pulled to slide. The sliding strip can drive the guide post to move through the guide groove. The guide post drives the connecting rod to rotate, and the connecting rod drives the rotating strip to rotate. When the rotating strip rotates 90°, the sand in the psychological sand tray can be discharged from the shell through the discharge port. At the same time, the operator can shake the psychological sand tray to accelerate the sand falling downwards. Compared with manually rotating the psychological sand tray and pouring out the sand, the sand will not scatter into the air, making it easier to remove the sand from the psychological sand tray. Finally, pull the sliding strip to reset. The sliding strip can drive the guide post to move through the guide groove. The guide post drives the connecting rod to rotate, and the connecting rod drives the rotating strip to rotate. After the rotating strip rotates 90° and resets, under the action of the rebound force of the second spring, one end of the limiting post inserts into the sliding strip, which can fix the position of the sliding strip and block the discharge port. Finally, the sand can be poured back into the psychological sand tray. The operation is simple, and the sand will not scatter when replacing it.

[0011] In the above technical solution, further, the two ends of several first springs are respectively welded to the sliding plate and the inner wall of the drive groove, and the two ends of the second springs are respectively welded to the inner wall of the limiting groove and the limiting post.

[0012] In this technical solution, it is ensured that the first springs and the second springs will not bend during use, and that the first springs and the second springs can be used stably.

[0013] In the above technical solution, the diameter of the sliding column is adapted to the size of the sliding groove, and the diameter of the guide column is adapted to the size of the guide groove.

[0014] In this technical solution, it is ensured that the sliding column can slide stably within the sliding groove, and the guide column can slide stably within the guide groove.

[0015] In the above technical solution, the psychological sand tray is further configured in a funnel shape.

[0016] This technical solution facilitates the removal of sand from the psychological sandbox by staff.

[0017] Furthermore, in the above technical solution, a handle is fixedly installed on the top of the housing.

[0018] In this technical solution, a handle is provided to facilitate users to carry several psychological sand trays to a designated location.

[0019] The beneficial effects of this utility model are: 1. This portable, multi-tiered pull-out psychological sandplay device allows for the removal of multiple sandplays for use. A drive sub-component drives several limiting plates to slide. Once these limiting plates detach from the fixing blocks, the sandplays can be pulled out of the housing. After use, all sandplays are inserted back into the housing, and the fixing blocks are inserted into the drive slots. The drive sub-component then fixes the positions of the fixing blocks, ultimately securing the sandplays. Users can carry multiple sandplays to a designated location, allowing for larger quantities to be carried at once and avoiding the waste of time and repeated transport.

[0020] 2. This portable, multi-tiered pull-out sand tray allows for sand replacement. A power unit drives a rotating bar to rotate and reset. After the bar rotates 90°, the sand can be discharged through the discharge port. Simultaneously, the operator can shake the sand tray to accelerate the sand's descent. Compared to manually rotating the tray and emptying the sand, the sand doesn't scatter into the air, making it easier to remove. The power unit also allows the rotating bar to rotate and reset. After rotating 90° and resetting, the discharge port can be blocked, allowing sand to be poured back into the tray. The operation is simple, and sand doesn't scatter during replacement.
