Abstract
The utility model discloses an elliptic spiral stair which comprises a supporting frame, an elliptic cage and a universal joint, wherein the elliptic cage is provided with an elliptic cage body and a rotary pedal, the lower end of the rotary pedal is connected with the ground, and the upper end of the rotary pedal is connected with the lower end of the elliptic cage body. The universal joint is provided with a universal shell and a transmission shaft, wherein the upper end of the universal shell is connected with the supporting frame, a spherical head arranged at one end of the transmission shaft is matched with the lower end of the universal shell, and the other end of the transmission shaft is connected with the upper end of the elliptic cage body. According to the elliptic spiral stair, the elliptic cage can rotate inside the universal joint through the transmission shaft in a multidirectional mode, the lower end of the elliptic cage offsets towards the left, the right, the front and the back to form certain angles with the ground, the installation height of the elliptic cage is regulated to complete installation of the elliptic spiral stair, requirements for the installation ground of the elliptic spiral stair are greatly reduced, and work efficiency is improved.
Description
Technical field
The utility model relates to a kind of recreation facility, is specifically related to a kind of ELLIPTIC REVOLUTION ladder.
Background technology
As everyone knows, the ELLIPTIC REVOLUTION ladder is the recreation facility commonly used that children's amusement is played, and is found everywhere children in recreation ground or garden, sub-district and rotates the scene of playing in spheroid.At present, the ELLIPTIC REVOLUTION ladder includes bracing frame, oval cage, oval cage one end is connected with ground, the other end is connected with bracing frame, and oval cage and bracing frame are fixing dead, can not disassemble, oval cage setting height(from bottom) can not change, often requiring that ground is installed need be smooth, but the open air broken terrain can occur unavoidably, will cause the ELLIPTIC REVOLUTION ladder to be difficult to install.
The utility model content
In order to overcome disadvantages of background technology, a kind of ELLIPTIC REVOLUTION ladder is provided, solve the unalterable defective of oval cage setting height(from bottom).
The technical scheme that the utility model adopted: a kind of ELLIPTIC REVOLUTION ladder, include bracing frame, oval cage, universal joint, described oval cage is provided with oval cage body, rotary pedals plate, described rotary pedals plate lower end is connected with ground, rotary pedals plate upper end is connected with oval cage body lower end, described universal joint is provided with universal shell, power transmission shaft, described universal shell upper end is connected with bracing frame, described power transmission shaft one end is provided with ballhead and matches with universal shell lower end, and the power transmission shaft other end is connected with oval cage body upper end.
Described universal shell includes universal upper casing and universal lower casing, be provided with through hole in the middle of the described universal upper casing, described universal upper casing is enclosed within on the bracing frame by through hole and fixes, described universal lower casing is fixed on universal upper casing below, described universal lower casing lower end is provided with groove, universal lower casing matches with the ballhead of power transmission shaft by groove, and described power transmission shaft can multi-faceted rotation in groove.
The utility model beneficial effect: described oval cage can be by power transmission shaft multi-faceted rotation in universal shell, make oval cage lower end angled with ground to the left, right, front and rear skew, adjust oval cage setting height(from bottom) and finish the installation of ELLIPTIC REVOLUTION ladder, reduce the ELLIPTIC REVOLUTION ladder greatly to the ground requirement is installed, increase work efficiency.
Description of drawings
Fig. 1 is a three-dimensional structure diagram of the present utility model.
Fig. 2 is the cutaway view of universal joint 3 among Fig. 1.
1-bracing frame among the figure, the oval cage of 2-, 3-universal joint, the oval cage body of 4-, 5-rotary pedals plate, the universal shell of 6-, 7-power transmission shaft, the universal upper casing of 61-, the universal lower casing of 62-, 63-through hole, 64-groove, 71-ballhead.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Referring to Fig. 1, shown in Figure 2, a kind of ELLIPTIC REVOLUTION ladder, include bracing frame 1, oval cage 2, universal joint 3, described oval cage 2 is provided with oval cage body 4, rotary pedals plate 5, described rotary pedals plate 5 lower ends are connected with ground, rotary pedals plate 5 upper ends are connected with oval cage body 4 lower ends, described universal joint 3 is provided with universal shell 6, power transmission shaft 7, described universal shell 6 includes universal upper casing 61 and universal lower casing 62, be provided with through hole 63 in the middle of the described universal upper casing 61, described universal upper casing 61 is enclosed within on the bracing frame 1 by through hole 63 and fixes, described universal lower casing 62 is fixed on universal upper casing 61 belows, described universal lower casing 62 lower ends are provided with groove 64, and universal lower casing 62 is provided with ballhead 71 by groove 64 with power transmission shaft 7 one ends and matches, and power transmission shaft 7 other ends are connected with oval cage body 4 upper ends.When ground relief is installed, can pass through power transmission shaft 7 multi-faceted rotation in groove 64, make oval cage 2 lower ends angled with ground to the left, right, front and rear skew, adjust oval cage setting height(from bottom) and finish the installation of ELLIPTIC REVOLUTION ladder, reduce the ELLIPTIC REVOLUTION ladder greatly to the ground requirement is installed, increase work efficiency.
