Description

Technical Field

[0001] This utility model relates to the field of column cap technology, specifically a column cap structure for children's amusement equipment. Background Technology

[0002] Columns and end caps are common components in mechanical structures and building components. Their design and application need to meet the functions of support, sealing, and connection in specific scenarios. The design of columns and end caps for children's amusement equipment should focus on "safety protection" and take into account the environmental friendliness of materials, the impact resistance of the structure, and the stability of the connection, while also taking into account the fun of children's use and the convenience of maintenance.

[0003] Existing caps on the market have a relatively simple function, serving only as caps. Welding thermal stress can cause deformation of the column (especially thin-walled steel pipes), affecting verticality. Installation is also inconvenient, and their decorative appeal is poor for children's playground equipment. Therefore, we propose a column cap structure for children's playground equipment to solve this problem. Utility Model Content

[0004] The purpose of this utility model is to provide a column cap structure for children's amusement equipment to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a column cap structure for children's amusement equipment, comprising a column, an end cap on the top of the column, an end piece above the end cap, a groove on the top surface of the end cap, a first bolt on the inner side of the end cap, the bottom end of the end cap extending into the interior of the column, a trapezoidal block at the bottom end of the end cap, a second through hole on the bottom surface of the end cap, a first through hole on the top surface of the trapezoidal block, the inner wall of the first through hole corresponding to the inner wall of the second through hole, the diameter of the inner wall of the first through hole and the diameter of the inner wall of the second through hole both being larger than the diameter of the first bolt screw and smaller than the diameter of the first bolt head, the bottom end of the first bolt penetrating the interior of the second through hole and the interior of the first through hole and extending to the bottom of the trapezoidal block, and a nut threaded onto the outer surface of the first bolt.

[0006] A further improvement is that a hexagonal groove is provided on the inner wall of the first through hole, a washer is fitted on the outer side of the first bolt, and the nut is set inside the hexagonal groove. The outer surface of the nut is adapted to the inner wall of the hexagonal groove. By setting the bolt, nut, end cap and trapezoidal block, rotating the bolt clamps the trapezoidal block and end cap, causing the trapezoidal block to deform the end cap by squeezing it, so that the end cap is fixed to the top of the column.

[0007] A further improvement is that the inner wall of the end cap is provided with a mating groove, the outer surface of the trapezoidal block extends into the mating groove and is adapted to the inner wall of the mating groove, and the outer surface of the bottom end of the end cap is pressed and contacted with the inner wall of the column. By setting the mating groove, it is convenient to limit the trapezoidal block and prevent the trapezoidal block from rotating during the rotation of the first bolt.

[0008] A further improvement is that a first annular groove is formed on the outer surface of the end cap, and the outer surface of the top of the column extends into the first annular groove and is adapted to the inner wall of the first annular groove. By setting the first annular groove, it is convenient for the end cap to be docked and positioned with the top of the column.

[0009] A further improvement is that the end piece is a small cap, the bottom end of which extends to the inside of the end cap, and the outer surface of the small cap is provided with a protrusion. The outer surface of the protrusion is interference-fitted with the inner wall of the end cap. By providing the small cap and the elastic protrusion, the small cap is stuck inside the end cap, thus protecting the first bolt.

[0010] A further improvement is that the end piece is a connecting pipe, the outer surface of the top end of the connecting pipe is provided with a second annular groove, a decorative column and a second bolt are provided above the connecting pipe, a decorative plate is integrally provided on the top of the decorative column, the top end of the connecting pipe extends into the interior of the decorative column, and the inner wall of the second annular groove is adapted to the inner wall of the bottom end of the decorative column. By setting the first annular groove, the connecting pipe and the decorative column, the fun of the device is enhanced.

[0011] A further improvement is that a third through hole is provided on the outer surface of the connecting pipe, and the inner wall of the third through hole is adapted to the inner wall of the second through hole. The connecting pipe is sleeved on the outside of the first bolt. By providing the third through hole, it is convenient for the first bolt to connect the connecting pipe, the end cap and the trapezoidal block.

[0012] A further improvement is that threaded holes are provided on the outer surfaces of both the connecting pipe and the decorative column. The thread on the outer surface of the second bolt passes through the threaded hole and extends to the inner side of the connecting pipe. By providing threaded holes and a second bolt, it is convenient to splice the decorative column with the connecting pipe, and at the same time, it is convenient to replace different types of decorative columns to decorate the column.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This children's amusement equipment uses a column cap structure, which includes an end cap, an end piece, a small cap, a first annular groove, a trapezoidal block, a nut, a first bolt, a washer, a protrusion, a mating groove, a hexagonal groove, a first through hole, and a second through hole. When in use, the hexagonal groove limits the nut, the mating groove limits the trapezoidal block, and by rotating the first bolt, the trapezoidal block presses against the inner wall of the end cap, causing the end cap to deform. The end cap is fixed by the pressure between the end cap and the column, and the top of the end cap is sealed by the pressure between the protrusion and the end cap. In the field of amusement design, the structure of this cap adopts a modular form, and through structural optimization, it can be locked with only one screw, making installation simple.
