[0048] Example 3

[0049] This embodiment provides a magnetic building block toy, which, in addition to the technical solutions of the above embodiments, also discloses a structure of an adjustment mechanism;

[0050] In this embodiment, the adjustment mechanism includes: an adjustment rod 501, a telescopic rod 502, a cam 503, a locking mechanism 6,

[0051] See also Figure 3 The adjusting rod 501 is arranged in the control groove 101 along the moving direction perpendicular to the track 3. One end of the adjusting rod 501 extends out of the housing 1. External force can drive the adjusting rod 501 to rotate. For details, please refer to Figure 2 A through hole 102 connected to the control groove 101 is provided on the side of the housing 1, and one end of the adjustment rod 501 passes through the through hole 102 and extends out of the housing 1;

[0052] The lower end of the telescopic rod 502 is fixed to the bottom surface of the control slot 101, and the other end of the telescopic rod 502 is connected to the bottom surface of the track 3;

[0053] The cam 503 is arranged on the adjusting rod 501, and the cam 503 contacts the bottom surface of the track 3. When the adjusting rod 501 rotates, the cam 503 is driven to rotate;

[0054] The locking mechanism 6 is used to lock the adjustment rod 501 at the current angle;

[0055] In this embodiment, please refer to Figure 3 , the contact point between the cam 503 and the bottom surface of the track 3 switches between the far center point of the cam 503 and the side surface of the cam 503, Figure 3 The distal points of the two cams 503 on the left side of the middle are in contact with the bottom surface of the track 3. At this time, the track 3 is at a higher position, that is, the second end of the track 3 extends out of the guide groove 2. Figure 3 The side surface of the cam 503 on the right side contacts the bottom surface of the track 3 . At this time, the track 3 is in a lower position, that is, the second end of the track 3 retreats into the guide groove 2 .

[0056] When the track 3 slides in the guide groove 2, the telescopic rod 502 will be extended and shortened, thereby guiding the moving direction of the track 3;

[0057] In this embodiment, in the initial state, the side surface of the cam 503 contacts the bottom surface of the track 3, and the track 3 is hidden in the guide groove 2. When the track 3 needs to be used, the rotating adjustment rod 501 drives the cam 503 to rotate, so that the contact point between the cam 503 and the track 3 moves from the side surface of the cam 503 to the distal point of the cam 503. In this process, the track 3 moves upward and extends out of the guide groove 2; when the track 3 is not needed, the rotating adjustment rod 501 drives the cam 503 to rotate, so that the contact point between the cam 503 and the track 3 moves from the distal point of the cam 503 to the side surface of the cam 503. At this time, a gap appears between the track 3 and the cam 503, and the track 3 moves downward and returns to the guide groove 2 under its own gravity.

[0058] Example 4

[0059] This embodiment provides a magnetic building block toy, which, in addition to the technical solutions of the above embodiments, also discloses a structure of a locking mechanism 6;

[0060] See also Figure 4 The locking mechanism 6 includes a locking groove 601, which is provided on the side wall of the control groove 101, and a plurality of slots 602 are provided on the side wall of the locking groove 601 at intervals along the circumferential direction;

[0061] A plurality of latch teeth 603 are provided at intervals along the circumferential direction on the outer peripheral wall near the end of one end of the adjusting rod 501. The end of the adjusting rod 501 can extend into the locking groove 601. The latch teeth 603 can engage with and disengage from the latch grooves 602 in the axial direction of the adjusting rod 501.

[0062] When the adjusting rod 501 needs to be rotated, the adjusting rod 501 is pulled out axially to separate the latch teeth 603 from the latch grooves 602. At this time, the adjusting rod 501 can be rotated. When the adjusting rod 501 is adjusted to a suitable position, the adjusting rod 501 is pushed axially into the locking groove 601 to mesh the latch teeth 603 with the latch grooves 602, thereby locking the adjusting rod 501.

[0063] See also Figure 5 The end of the adjusting rod 501 at which the latching tooth 603 is provided also has a cylindrical section, so that when the latching tooth 603 is separated from the latching groove 602, part of the adjusting rod 501 is still located in the locking groove 601, thereby ensuring the stable rotation of the adjusting rod 501;

[0064] See also Figure 5 A force block 7 is provided at one end of the adjusting rod 501 located outside the shell 1, and a pull ring 8 is provided on the force block 7; through the cooperation of the pull ring 8 and the force block 7, the adjusting rod 501 can be easily driven axially to move and rotate the adjusting rod 501; in addition, through the strip setting of the pull ring 8, the contact position of the cam 503 and the bottom surface of the track 3 can be quickly identified.

[0065] Example 5

[0066] This embodiment provides a magnetic building block toy, which, in addition to the technical solutions of the above embodiments, also optimizes the movement mode of the track 3;

[0067] See also Figure 3 The outer sleeve of the telescopic rod 502 is provided with a spring 9, and the two ends of the spring 9 are respectively connected to the bottom surface of the control groove 101 and the track 3. When the track 3 is at the lowest position, that is, the track 3 is hidden in the guide groove 2, the spring 9 is in a normal state. During the upward movement of the track 3, the spring 9 is stretched and accumulates elastic force. During the movement of the contact point between the cam 503 and the track 3 from the distal point of the cam 503 to the side of the cam 503, the elastic force of the spring 9 will pull the track 3 downward, so that the track 3 is always in contact with the cam 503. Compared with relying on the downward movement of the track 3 by its own gravity, this can prevent the track 3 from being stuck, thereby improving the stability of the magnetic building block toy structure.

[0068] The embodiments of the utility model are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive.
