Description

Technical Field

[0001] This utility model relates to the field of amusement facilities technology, and more specifically, to a sandpit amusement equipment. Background Technology

[0002] Sandpit playground equipment has always held an important position in the field of children's play. Early sandpits were relatively simple, consisting of sand piled up in a fixed area and some basic toys such as small plastic shovels and buckets. With the development of technology and the improvement of people's requirements for children's play experience, sandpit playground equipment has been continuously upgraded.

[0003] Traditional support frames are simply connected to the ground, and there is no special anti-slip fixing structure at the bottom of the equipment. The anti-slip mat is easy to shift, and children are prone to slipping on sand when getting on and off the equipment, posing a great safety hazard. The rotating shaft of the existing amusement equipment rubs directly against the sleeve without effective lubrication. After long-term use, the wear will increase, causing the bucket to jam and affecting the play experience. Utility Model Content

The fixing ring 12 is symmetrically provided with There are a first fixing member 13 and a second fixing member 14. The outer side of the first fixing member 13 and the second fixing member 14 is provided with a fixing cover 15. The fixing cover 15 and the fixing protruding ring 11 are connected by a fixing bolt 16 in a circumferential thread. The first fixing member 13 is provided with an insertion block 17 horizontally. The fixing sleeve 10 is provided with an insertion groove 18 that mates with the insertion block 17. Multiple insertion blocks 17 and insertion grooves 18 are symmetrically arranged. The second fixing member 14 is provided with an insertion rod 19 vertically. The first fixing member 13 and the fixing ring 12 are provided with insertion holes 20 that mate with the insertion rod 19. Multiple insertion rods 19 and insertion holes 20 are provided correspondingly. In this embodiment, the fixing sleeve 10 is fitted onto the rod of the support frame 3 and rests inside the fixing protrusion 11 of the anti-slip pad 9, improving the tightness of the connection between the fixing protrusion 11 and the support frame 3. Both the first fixing member 13 and the second fixing member 14 are semi-ring-shaped structures. The insertion block 17 of the first fixing member 13 is inserted into the insertion groove 18 of the fixing sleeve 10, and the insertion rod 19 of the second fixing member 14 is inserted into the insertion holes 20 of the first fixing member 13 and the fixing ring 12, thereby connecting the first fixing member 13, the second fixing member 14, the fixing ring 12, and the fixing sleeve 10. A fixing cover 15 is fitted over the outer side of the first fixing member 13, the second fixing member 14, the fixing ring 12, and the fixing sleeve 10. The fixing protruding ring 11 and the fixing cover 15 are connected and fixed by fixing bolts 16. Through the cooperation of the first fixing member 13, the second fixing member 14, the fixing ring 12, the fixing sleeve 10, and the fixing cover 15, the fixing protruding ring 11 and the anti-slip pad 9 are installed and fixed to prevent children from slipping when they get off the main body 2 of the facility. When children sit on the seat of the support frame 3, they can pull the two levers 7 to drive the connecting rod 8 to rotate, which in turn drives the bucket 4 to flip and shovel sand for fun.

[0022] Please see Figure 5As one embodiment of lubrication of the rotating shaft 5: the rotating shaft 5 is provided with axial and circumferential ball bearings 21, the rotating shaft 5 is provided with an oil injection groove 22 and a lubrication groove 23, the oil injection groove 22 is provided with a piston rod 24, one end of the piston rod 24 is provided with a piston plate 25 that cooperates with the oil injection groove 22, one end of the piston rod 24 is provided with an oil injection plate 26, a tension spring 27 is provided between the oil injection plate 26 and the rotating shaft 5, the top of the oil injection groove 22 is provided with an oil injection hole 28, a baffle 29 is provided inside the oil injection groove 22, and a compression spring 30 is provided between the baffle 29 and the oil injection groove 22.

[0023] More specifically, the area between the rotating shaft 5 and the rotating sleeve 6 is prone to wear and requires maintenance. During lubrication, the lubrication plate 26 and piston rod 24 are pulled to one side, thereby stretching the tension spring 27. At the same time, the piston rod 24 drives the piston plate 25 to move to one side, causing the baffle 29 to move to one side and compress the compression spring 30. The baffle 29 moves to one side to open the lubrication hole 28, injecting lubricating oil into the lubrication groove 22. After the injection is completed, the lubrication plate 26 is released, and the lubrication plate 26 moves downward under the elastic force of the tension spring 27. The piston moves, causing the piston rod 24 and piston plate 25 to squeeze the lubricating oil. The oil is blocked at the oil injection hole 28 by the baffle 29 under the elastic force of the compression spring 30, preventing oil leakage and lubricating oil contamination. Under pressure, the lubricating oil enters the lubrication groove 23 from the oil injection groove 22. When the rotating plate rotates, the friction between the rotating sleeve 6 and the rotating shaft 5 is reduced by the ball bearings 21. The ball bearings 21 also pick up the lubricating oil and lubricate the rotating sleeve 6 and the rotating shaft 5, reducing the wear between the rotating shaft 5 and the rotating sleeve 6.

[0024] In summary, during use or operation of the overall equipment: the fixing sleeve 10 is fitted onto the rod of the support frame 3 and placed inside the fixing protrusion 11 of the anti-slip pad 9, improving the tightness of the connection between the fixing protrusion 11 and the support frame 3. Both the first fixing member 13 and the second fixing member 14 are semi-ring-shaped structures. The insertion block 17 of the first fixing member 13 is inserted into the insertion groove 18 of the fixing sleeve 10, and the insertion rod 19 of the second fixing member 14 is inserted into the insertion holes 20 of the first fixing member 13 and the fixing ring 12, thereby securing the first fixing member 13, the second fixing member 14, the fixing ring 12, and the fixing sleeve 10. The connection is made by fitting a fixing cover 15 on the outside of the first fixing member 13, the second fixing member 14, the fixing ring 12, and the fixing sleeve 10. The fixing protruding ring 11 and the fixing cover 15 are connected and fixed by fixing bolts 16. The fixing protruding ring 11 and the anti-slip pad 9 are installed and fixed by the cooperation of the first fixing member 13, the second fixing member 14, the fixing ring 12, the fixing sleeve 10 and the fixing cover 15 to prevent children from slipping when they get off the main body 2 of the facility. When the child sits on the seat of the support frame 3, he pulls the two levers 7 to drive the connecting rod 8 to rotate, which in turn drives the bucket 4 to flip and shovel sand for fun.

[0025] The area between the rotating shaft 5 and the rotating sleeve 6 is prone to wear and requires maintenance. During lubrication, the lubrication plate 26 and piston rod 24 are pulled to one side, which stretches the tension spring 27. Simultaneously, the piston rod 24 moves the piston plate 25 to one side, causing the baffle 29 to move to one side and compress the compression spring 30. The baffle 29 moves to one side, opening the lubrication hole 28 and injecting lubricating oil into the lubrication groove 22. After injection, the lubrication plate 26 is released, and it moves downward under the elastic force of the tension spring 27. The piston rod 24 and piston plate 25 are driven to squeeze the lubricating oil. The oil is blocked at the oil injection hole 28 by the baffle 29 under the elastic force of the compression spring 30 to prevent oil leakage and lubricating oil contamination. Under pressure, the lubricating oil enters the lubrication groove 23 from the oil injection groove 22. When the rotating plate rotates, the friction between the rotating sleeve 6 and the rotating shaft 5 is reduced by the ball bearing 21. The ball bearing 21 also picks up the lubricating oil and lubricates the rotating sleeve 6 and the rotating shaft 5, reducing the wear between the rotating shaft 5 and the rotating sleeve 6.
