Description

Technical Field

[0001] The utility model relates to the technical field of children's drawing boards, in particular to a fall-proof double-sided children's drawing board. Background Art

[0002] A drawing board refers to a flat board used to pad drawing paper when painting. A children's drawing board is a skateboard specially used by children. It can cultivate children's creativity and imagination, improve children's aesthetic ability, help complete the development of vision and movement, and promote the growth of children's cognitive ability.

[0003] Nowadays, most children's drawing boards are made of plastic with simple structure. The intelligence of some young children is not fully developed. They like to smash things to vent their emotions. Children's drawing boards may be directly damaged when they are hit by brushes or smashes.

[0004] According to the search, Chinese patent literature, announcement number: CN211222866U, discloses a drop-proof children's drawing board. The shock-absorbing mechanism can effectively provide shock-absorbing protection for the main body of the drawing board, and the shock-absorbing mechanism is set between the rubber inner protective ring and the outer protective ring, which can provide more effective protection for the main body of the drawing board. On the other hand, the main body of the drawing board is embedded in the embedding groove on the inner protective ring, so that when the front of the drawing board falls to the ground, the main body of the drawing board will not directly contact the ground, which can more comprehensively protect the main body of the drawing board, making it less likely to be broken and damaged, and the service life of the drawing board is longer. However, the drop-proof structure of the drop-proof children's drawing board can only be applied to round drawing boards, not to traditional square drawing boards. Round drawing boards can only be placed on the desktop for use, do not have the function of tilting, and are inconvenient to operate. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Embodiment 1:

[0032] like Figure 1-5 As shown, the utility model provides a fall-proof double-sided children's drawing board, comprising an outer frame 1 and a drawing board 2, a traction rope 3 is fixedly installed at the lower end of the outer frame 1, a limiting groove 4 is arranged inside the outer frame 1, limiting blocks 5 are fixedly installed at the upper and lower ends of the drawing board 2, one end of a spring 6 is fixedly installed on the inner side of the limiting groove 4, an inner sleeve 7 is fixedly installed on the outer side of the outer frame 1, a guide rod 8 is movably installed on the inner side of the inner sleeve 7, a movable rod 9 is fixedly installed on the outer side of the guide rod 8, one end of a spring 10 is fixedly installed inside the movable rod 9, a rubber pad 11 is fixedly installed on the lower end of the movable rod 9, and an air bag 12 is fixedly installed on the outer side of the movable rod 9.

[0033] Specifically, four outer frames 1 are provided, the upper ends of the outer frames 1 are rotatably connected by hinges, and two traction ropes 3 are provided. The advantage is that when painting, the outer frame 1 is unfolded to both sides and placed on the desktop, and the traction ropes 3 play a limiting role on the outer frame 1.

[0034] Specifically, the left and right ends of the drawing board 2 extend to the inside of the outer frame 1, and the limit blocks 5 fit the inner sides of the limit grooves 4. The advantage is that when the outer frame 1 is subjected to impact forces in the left and right directions, the outer frame 1 moves horizontally along the two ends of the drawing board 2, and the limit blocks 5 limit the two ends of the drawing board 2.

[0035] Specifically, two springs 1 6 are respectively arranged on the inner side of the limit groove 4, and the other end of the spring 1 6 is fixedly connected to the left and right ends of the drawing board 2. The advantage is that when the outer frame 1 moves toward the drawing board 2, the spring 1 6 is compressed, which plays a buffering role on the outer frame 1.

[0036] Embodiment 2:

[0037] like Figure 1-5 As shown, as an improvement to the previous embodiment, specifically, the movable rod 9 is fitted with the outer side of the outer frame 1, and the movable rod 9 extends to the bottom of the outer frame 1. The advantage is that the guide rod 8 slides up and down along the inner side of the inner sleeve 7, guiding the movable rod 9.

[0038] Specifically, two springs 10 are respectively arranged inside the movable rod 9, and the springs 10 are sleeved and installed on the outside of the guide rod 8, and the other end of the springs 10 is fixedly connected to the inner sleeve 7. The advantage is that when the movable rod 9 moves, the springs 10 are compressed, which plays a buffering role on the movable rod 9.

[0039] Specifically, four rubber pads 11 and four air bags 12 are respectively provided. The advantage is that the rubber pads 11 and the air bags 12 play a protective role on the outer side of the movable rod 9.

[0040] When in use, the outer frame 1 is unfolded to both sides and placed on the desktop. The traction rope 3 limits the outer frame 1. The drawing boards 2 on both sides can be used for drawing. When the drawing boards fall to the ground, the rubber pads 11 and the air bags 12 protect the outer sides of the movable rods 9. When the outer frame 1 is subjected to impact forces in the left and right directions, it moves horizontally along the two ends of the drawing board 2. The limit blocks 5 limit the two ends of the drawing board 2. When the outer frame 1 moves, the limit groove 4 and the spring 6 are compressed, which buffers the outer frame 1. When the movable rod 9 is subjected to impact forces in the vertical direction, the internal guide rod 8 slides up and down along the inner side of the inner sleeve 7, guiding the movable rod 9. At the same time, the internal spring 10 is compressed, which buffers the movable rod 9, avoiding direct damage to the drawing board 2 caused by the impact, and effectively improving the anti-fall performance of the children's drawing board.
